ruv 8f927aaedb feat(server): per-node state pipeline for multi-node sensing (ADR-068, #249)
Replaces the single shared state pipeline with per-node HashMap<u8, NodeState>.
Each ESP32 node now gets independent:
- frame_history (temporal analysis)
- smoothed_person_score / prev_person_count
- smoothed_motion / baseline / debounce state
- vital sign detector + smoothing buffers
- RSSI history

Multi-node aggregation:
- Person count = sum of per-node counts for active nodes (seen <10s)
- SensingUpdate.nodes includes all active nodes
- estimated_persons reflects cross-node aggregate

Single-node deployments behave identically (HashMap has one entry).
Simulated data path unchanged for backward compatibility.

Closes #249
Refs #237, #276, #282

ruv 635c152e61 docs(adr): ADR-068 per-node state pipeline for multi-node sensing (#249)
Documents the architectural change from single shared state to per-node
HashMap<u8, NodeState> in the sensing server. Includes scaling analysis
(256 nodes < 13 MB), QEMU validation plan, and aggregation strategy.

## [Unreleased]
### Fixed
- **Ghost skeletons in live UI with multi-node ESP32 setups** (#420, ADR-082) —
`tracker_bridge::tracker_to_person_detections` documented itself as filtering
to `is_alive()` tracks but in fact passed every non-Terminated track to the
WebSocket stream. `Lost` tracks — kept inside `reid_window` for
re-identification but not currently observed — were rendering as phantom
skeletons, accumulating to 22-24 with 3 nodes × 10 Hz CSI while
`estimated_persons` correctly reported 1. Added
`PoseTracker::confirmed_tracks()` (Tentative + Active only) and rewired the
bridge to use it. Lost tracks remain in the tracker for re-ID; they just
no longer ship to the UI. Regression test:
`test_lost_tracks_excluded_from_bridge_output`.
- **Rust workspace build with `--no-default-features` on Windows** (#366, #415) —
`wifi-densepose-mat`, `wifi-densepose-sensing-server`, and `wifi-densepose-train`
all depended on `wifi-densepose-signal` with default features enabled, which
pulled `ndarray-linalg``openblas-src` → vcpkg/system-BLAS through the entire
workspace. `--no-default-features` at the workspace root then could not opt out
of BLAS, breaking `cargo build` / `cargo test` on Windows without vcpkg. All
three consumers now declare `wifi-densepose-signal = { ..., default-features = false }`,
so `cargo test --workspace --no-default-features` builds cleanly without
vcpkg/openblas. Validated: 1,538 tests pass, 0 fail, 8 ignored.
- **`signal` test `test_estimate_occupancy_noise_only` failed without `eigenvalue`** —
The test unwrapped the `NotCalibrated` stub returned when the BLAS-backed
`estimate_occupancy` is compiled out. Gated with `#[cfg(feature = "eigenvalue")]`
so it only runs when the real implementation is available.
## [v0.6.2-esp32] — 2026-04-20
Firmware release cutting ADR-081 and the Timer Svc stack fix discovered during
on-hardware validation. Cut from `main` at commit pointing to this entry.
Tested on ESP32-S3 (QFN56 rev v0.2, MAC `3c:0f:02:e9:b5:f8`), 30 s continuous
run: no crashes, 149 `rv_feature_state_t` emissions (~5 Hz), medium/slow ticks
firing cleanly, HEALTH mesh packets sent.
### Fixed
- **Firmware: Timer Svc stack overflow on ADR-081 fast loop** — `emit_feature_state()` runs inside the FreeRTOS Timer Svc task via the fast-loop callback; it calls `stream_sender` network I/O which pushes past the ESP-IDF 2 KiB default timer stack and panics ~1 s after boot. Bumped `CONFIG_FREERTOS_TIMER_TASK_STACK_DEPTH` to 8 KiB in `sdkconfig.defaults`, `sdkconfig.defaults.template`, and `sdkconfig.defaults.4mb`. Follow-up (tracked separately): move heavy work out of the timer daemon into a dedicated worker task.
- **Firmware: `adaptive_controller.c` implicit declaration** (#404) — `fast_loop_cb` called `emit_feature_state()` before its static definition, triggering `-Werror=implicit-function-declaration`. Added a forward declaration above the first use.
### Changed
- **CI: firmware build matrix (8MB + 4MB)** — `firmware-ci.yml` now matrix-builds both the default 8MB (`sdkconfig.defaults`) and 4MB SuperMini (`sdkconfig.defaults.4mb`) variants, uploading distinct artifacts and producing variant-named release binaries (`esp32-csi-node.bin` / `esp32-csi-node-4mb.bin`, `partition-table.bin` / `partition-table-4mb.bin`).
### Added
- **ADR-081: Adaptive CSI Mesh Firmware Kernel** — New 5-layer architecture
(Radio Abstraction Layer / Adaptive Controller / Mesh Sensing Plane /
On-device Feature Extraction / Rust handoff) that reframes the existing
ESP32 firmware modules as components of a chipset-agnostic kernel. ADR
in `docs/adr/ADR-081-adaptive-csi-mesh-firmware-kernel.md`. Goal: swap
one radio family for another without changing the Rust signal /
ruvector / train / mat crates.
- **Firmware: radio abstraction vtable (`rv_radio_ops_t`)** — New
`firmware/esp32-csi-node/main/rv_radio_ops.{h}` defines the
chipset-agnostic ops (init, set_channel, set_mode, set_csi_enabled,
set_capture_profile, get_health), profile enum
(`RV_PROFILE_PASSIVE_LOW_RATE` / `ACTIVE_PROBE` / `RESP_HIGH_SENS` /
`FAST_MOTION` / `CALIBRATION`), and health snapshot struct.
`rv_radio_ops_esp32.c` provides the ESP32 binding wrapping
`csi_collector` + `esp_wifi_*`. A second binding (mock or alternate
chipset) is the portability acceptance test for ADR-081.
- **Firmware: `rv_feature_state_t` packet (magic `0xC5110006`)** — New
60-byte compact per-node sensing state (packed, verified by
`_Static_assert`) in `firmware/esp32-csi-node/main/rv_feature_state.h`:
motion, presence, respiration BPM/conf, heartbeat BPM/conf, anomaly
score, env-shift score, node coherence, quality flags, IEEE CRC32.
Replaces raw ADR-018 CSI as the default upstream stream (~99.7%
bandwidth reduction: 300 B/s at 5 Hz vs. ~100 KB/s raw).
- **Firmware: mock radio ops binding for QEMU** — New
`firmware/esp32-csi-node/main/rv_radio_ops_mock.c`, compiled only when
`CONFIG_CSI_MOCK_ENABLED`. Satisfies ADR-081's portability acceptance
test: a second `rv_radio_ops_t` binding compiles and runs against the
same controller + mesh-plane code as the ESP32 binding.
- **Firmware: feature-state emitter wired into controller fast loop** —
`adaptive_controller.c` now emits one 60-byte `rv_feature_state_t` per
fast tick (default 200 ms → 5 Hz), pulling from the latest edge vitals
and controller observation. This is the first end-to-end Layer 4/5
path for ADR-081.
- **Firmware: `csi_collector_get_pkt_yield_per_sec()` /
`_get_send_fail_count()` accessors** — Expose the CSI callback rate
and UDP send-failure counter so the ESP32 radio ops binding can
populate `rv_radio_health_t.pkt_yield_per_sec` and `.send_fail_count`,
closing the adaptive controller's observation loop.
- **Firmware: host-side unit test suite for ADR-081 pure logic** — New
`firmware/esp32-csi-node/tests/host/` (Makefile + 2 test files + shim
`esp_err.h`). Exercises `adaptive_controller_decide()` (9 test cases:
degraded gate on pkt-yield collapse + coherence loss, anomaly > motion,
motion → SENSE_ACTIVE, aggressive cadence, stable presence →
RESP_HIGH_SENS, empty-room default, hysteresis, NULL safety) and
`rv_feature_state_*` helpers (size assertion, IEEE CRC32 known
vectors, determinism, receiver-side verification). 33/33 assertions
pass. Benchmarks: decide() 3.2 ns/call, CRC32(56 B) 614 ns/pkt
(87 MB/s), full finalize() 616 ns/call. Pure function
`adaptive_controller_decide()` extracted to
`adaptive_controller_decide.c` so the firmware build and the host
tests share a single source-of-truth implementation.
- **Scripts: `validate_qemu_output.py` ADR-081 checks** — Validator
(invoked by ADR-061 `scripts/qemu-esp32s3-test.sh` in CI) gains three
checks for adaptive controller boot line, mock radio ops
registration, and slow-loop heartbeat, so QEMU runs regression-gate
Layer 1/2 presence.
- **Firmware: ADR-081 Layer 3 mesh sensing plane** — New
`firmware/esp32-csi-node/main/rv_mesh.{h,c}` defines 4 node roles
(Anchor / Observer / Fusion relay / Coordinator), 7 on-wire message
types (TIME_SYNC, ROLE_ASSIGN, CHANNEL_PLAN, CALIBRATION_START,
FEATURE_DELTA, HEALTH, ANOMALY_ALERT), 3 authorization classes
(None / HMAC-SHA256-session / Ed25519-batch), `rv_node_status_t`
(28 B), `rv_anomaly_alert_t` (28 B), `rv_time_sync_t`,
`rv_role_assign_t`, `rv_channel_plan_t`, `rv_calibration_start_t`.
Pure-C encoder/decoder (`rv_mesh_encode()` / `rv_mesh_decode()`) with
16-byte envelope + payload + IEEE CRC32 trailer; convenience encoders
for each message type. Controller now emits `HEALTH` every slow-loop
tick (30 s default) and `ANOMALY_ALERT` on state transitions to ALERT
or DEGRADED. Host tests: `test_rv_mesh` exercises 27 assertions
covering roundtrip, bad magic, truncation, CRC flipping, oversize
payload rejection, and encode+decode throughput (1.0 μs/roundtrip
on host).
- **Rust: ADR-081 Layer 1/3 mirror module** — New
`crates/wifi-densepose-hardware/src/radio_ops.rs` mirrors the
firmware-side `rv_radio_ops_t` vtable as the Rust `RadioOps` trait
(init, set_channel, set_mode, set_csi_enabled, set_capture_profile,
get_health) and provides `MockRadio` for offline testing.
Also mirrors the `rv_mesh.h` types (`MeshHeader`, `NodeStatus`,
`AnomalyAlert`, `MeshRole`, `MeshMsgType`, `AuthClass`) and ships
byte-identical `crc32_ieee()`, `decode_mesh()`, `decode_node_status()`,
`decode_anomaly_alert()`, and `encode_health()`. Exported from
`lib.rs`. 8 unit tests pass; `crc32_matches_firmware_vectors`
verifies parity with the firmware-side test vectors
(`0xCBF43926` for `"123456789"`, `0xD202EF8D` for single-byte zero),
and `mesh_constants_match_firmware` asserts `MESH_MAGIC`,
`MESH_VERSION`, `MESH_HEADER_SIZE`, and `MESH_MAX_PAYLOAD` match
`rv_mesh.h` byte-for-byte. Satisfies ADR-081's portability
acceptance test: signal/ruvector/train/mat crates are untouched.
- **Firmware: adaptive controller** — New
`firmware/esp32-csi-node/main/adaptive_controller.{c,h}` implements
the three-loop closed-loop control specified by ADR-081: fast
(~200 ms) for cadence and active probing, medium (~1 s) for channel
selection and role transitions, slow (~30 s) for baseline
recalibration. Pure `adaptive_controller_decide()` policy function is
exposed in the header for offline unit testing. Default policy is
conservative (`enable_channel_switch` and `enable_role_change` off);
Kconfig surface added under "Adaptive Controller (ADR-081)".
### Fixed
- **`provision.py` esptool v5 compat** (#391) — Stale `write_flash` (underscore) syntax in the dry-run manual-flash hint now uses `write-flash` (hyphenated) for esptool >= 5.x. The primary flash command was already correct.
- **`provision.py` silent NVS wipe** (#391) — The script replaces the entire `csi_cfg` NVS namespace on every run, so partial invocations were silently erasing WiFi credentials and causing `Retrying WiFi connection (10/10)` in the field. Now refuses to run without `--ssid`, `--password`, and `--target-ip` unless `--force-partial` is passed. `--force-partial` prints a warning listing which keys will be wiped.
- **Firmware: defensive `node_id` capture** (#232, #375, #385, #386, #390) — Users on multi-node deployments reported `node_id` reverting to the Kconfig default (`1`) in UDP frames and in the `csi_collector` init log, despite NVS loading the correct value. The root cause (memory corruption of `g_nvs_config`) has not been definitively isolated, but the UDP frame header is now tamper-proof: `csi_collector_init()` captures `g_nvs_config.node_id` into a module-local `s_node_id` once, and `csi_serialize_frame()` plus all other consumers (`edge_processing.c`, `wasm_runtime.c`, `display_ui.c`, `swarm_bridge_init`) read it via the new `csi_collector_get_node_id()` accessor. A canary logs `WARN` if `g_nvs_config.node_id` diverges from `s_node_id` at end-of-init, helping isolate the upstream corruption path. Validated on attached ESP32-S3 (COM8): NVS `node_id=2` propagates through boot log, capture log, init log, and byte[4] of every UDP frame.

- **No detection from edge vitals (#323)** — Server now generates `sensing_update` from Tier 2+ vitals packets.
- **RSSI byte offset mismatch (#332)** — Server parsed RSSI from wrong byte (was reading sequence counter).
- **Stack overflow risk** — Moved 4KB of BPM scratch buffers from stack to static storage.

## **See through walls with WiFi** ##
## **See through walls with WiFi + Ai** ##
**Turn ordinary WiFi into a sensing system.** Detect people, measure breathing and heart rate, track movement, and monitor rooms — through walls, in the dark, with no cameras or wearables. Just physics.
**Perceive the world through signals.** No cameras. No wearables. No Internet. Just physics.
### π RuView is a WiFi sensing platform that turns radio signals into spatial intelligence.
### π RuView is an edge AI perception system that learns directly from the environment around it.
Every WiFi router already fills your space with radio waves. When people move, breathe, or even sit still, they disturb those waves in measurable ways. RuView captures these disturbances using Channel State Information (CSI) from low-cost ESP32 sensors and turns them into actionable data: who's there, what they're doing, and whether they're okay.
Instead of relying on cameras or cloud models, it observes whatever signals exist in a space such as WiFi, radio waves across the spectrum, motion patterns, vibration, sound, or other sensory inputs and builds an understanding of what is happening locally.
**What it senses:**
- **Presence and occupancy** — detect people through walls, count them, track entries and exits
- **Vital signs** — breathing rate and heart rate, contactless, while sleeping or sitting
- **Activity recognition** — walking, sitting, gestures, falls — from temporal CSI patterns
- **Environment mapping** — RF fingerprinting identifies rooms, detects moved furniture, spots new objects
- **Sleep quality** — overnight monitoring with sleep stage classification and apnea screening
Built on top of [RuVector](https://github.com/ruvnet/ruvector/) Self Learning Vector Memory system and [Cognitum.One](https://Cognitum.One) , the project became widely known for its implementation of WiFi DensePose — a sensing technique first explored in academic research such as Carnegie Mellon University's *DensePose From WiFi* work. That research demonstrated that WiFi signals can be used to reconstruct human pose.
Built on [RuVector](https://github.com/ruvnet/ruvector/) and [Cognitum Seed](https://cognitum.one), RuView runs entirely on edge hardware — an ESP32 mesh (as low as $9 per node) paired with a Cognitum Seed for persistent memory, cryptographic attestation, and AI integration. No cloud, no cameras, no internet required.
RuView extends that concept into a practical edge system. By analyzing Channel State Information (CSI) disturbances caused by human movement, RuView reconstructs body position, breathing rate, heart rate, and presence in real time using physics-based signal processing and machine learning.
The system learns each environment locally using spiking neural networks that adapt in under 30 seconds, with multi-frequency mesh scanning across 6 WiFi channels that uses your neighbors' routers as free radar illuminators. Every measurement is cryptographically attested via an Ed25519 witness chain.
Unlike research systems that rely on synchronized cameras for training, RuView is designed to operate entirely from radio signals and self-learned embeddings at the edge.
RuView also supports pose estimation (17 COCO keypoints via the WiFlow architecture), trained entirely without cameras using 10 sensor signals — a technique pioneered from the original *DensePose From WiFi* research at Carnegie Mellon University.
The system runs entirely on inexpensive hardware such as an ESP32 sensor mesh (as low as ~$1 per node). Small programmable edge modules analyze signals locally and learn the RF signature of a room over time, allowing the system to separate the environment from the activity happening inside it.
Because RuView learns in proximity to the signals it observes, it improves as it operates. Each deployment develops a local model of its surroundings and continuously adapts without requiring cameras, labeled data, or cloud infrastructure.
In practice this means ordinary environments gain a new kind of spatial awareness. Rooms, buildings, and devices begin to sense presence, movement, and vital activity using the signals that already fill the space.

> [!NOTE]
> **CSI-capable hardware recommended.** Presence, vital signs, through-wall sensing, and all advanced capabilities require Channel State Information (CSI) from an ESP32-S3 ($9) or research NIC. The Docker image runs with simulated data for evaluation. Consumer WiFi laptops provide RSSI-only presence detection.
> **CSI-capable hardware required.** Pose estimation, vital signs, and through-wall sensing rely on Channel State Information (CSI) — per-subcarrier amplitude and phase data that standard consumer WiFi does not expose. You need CSI-capable hardware (ESP32-S3 or a research NIC) for full functionality. Consumer WiFi laptops can only provide RSSI-based presence detection, which is significantly less capable.

### Real-Time Dense Point Cloud (NEW)
RuView now generates **real-time 3D point clouds** by fusing camera depth + WiFi CSI + mmWave radar. All sensors stream simultaneously into a unified spatial model.
| Sensor | Data | Integration |
|--------|------|-------------|
| **Camera** | MiDaS monocular depth (GPU) | 640×480 → 19,200+ depth points per frame |
| **ESP32 CSI** | ADR-018 binary frames (UDP) | RF tomography → 8×8×4 occupancy grid |
| **WiFlow Pose** | 17 COCO keypoints from CSI | Skeleton overlay on point cloud |
| **Vital Signs** | Breathing rate from CSI phase | Stored in ruOS brain every 60s |
| **Motion** | CSI amplitude variance | Adaptive capture rate (skip depth when still) |
**Quick start:**
```bash
cd v2
cargo build --release -p wifi-densepose-pointcloud
./target/release/ruview-pointcloud serve --bind 127.0.0.1:9880
# Open http://localhost:9880 for live 3D viewer
```
**CLI commands:**
```bash
ruview-pointcloud demo # synthetic demo
ruview-pointcloud serve --bind 127.0.0.1:9880 # live server + Three.js viewer
ruview-pointcloud capture --output room.ply # capture to PLY
ruview-pointcloud train # depth calibration + DPO pairs
ruview-pointcloud cameras # list available cameras
ruview-pointcloud csi-test --count 100 # send test CSI frames
ruview-pointcloud fingerprint office --seconds 5 # record named CSI room fingerprint
```
The HTTP/viewer server defaults to **loopback (`127.0.0.1`)** — exposing live camera/CSI/vitals on `0.0.0.0` is an explicit opt-in. Brain URL defaults to `http://127.0.0.1:9876` and is overridable via `RUVIEW_BRAIN_URL` env var or the `--brain` flag on `serve`/`train`.
The pose overlay currently uses an **amplitude-energy heuristic** (`heuristic_pose_from_amplitude`) rather than trained WiFlow inference — real ONNX/Candle inference is tracked as a follow-up.
**Performance:** 22ms pipeline, 905 req/s API, 40K voxel room model from 20 frames.
**Brain integration:** Spatial observations (motion, vitals, skeleton, occupancy) sync to the ruOS brain every 60 seconds for agent reasoning.
See [PR #405](https://github.com/ruvnet/RuView/pull/405) for full details.
### What's New in v0.7.0
<details>
<summary><strong>Camera Ground-Truth Training — 92.9% PCK@20</strong></summary>
**v0.7.0 adds camera-supervised pose training** using MediaPipe + real ESP32 CSI data:
| Capability | What it does | ADR |
|-----------|-------------|-----|
| **Camera ground-truth collection** | MediaPipe PoseLandmarker captures 17 COCO keypoints at 30fps, synced with ESP32 CSI | [ADR-079](docs/adr/ADR-079-camera-ground-truth-training.md) |
| **ruvector subcarrier selection** | Variance-based top-K reduces input by 50% (70→35 subcarriers) | ADR-079 O6 |
| **Stoer-Wagner min-cut** | Person-specific subcarrier cluster separation for multi-person training | ADR-079 O8 |
| **Scalable WiFlow model** | 4 presets: lite (189K) → small (474K) → medium (800K) → full (7.7M params) | ADR-079 |
```bash
# Collect ground truth (camera + ESP32 simultaneously)
python scripts/collect-ground-truth.py --duration 300 --preview
python scripts/record-csi-udp.py --duration 300
# Align CSI windows with camera keypoints
node scripts/align-ground-truth.js --gt data/ground-truth/*.jsonl --csi data/recordings/*.csi.jsonl
# Train WiFlow model (start lite, scale up as data grows)
node scripts/train-wiflow-supervised.js --data data/paired/*.jsonl --scale lite
# Evaluate
node scripts/eval-wiflow.js --model models/wiflow-real/wiflow-v1.json --data data/paired/*.jsonl
```
**Result: 92.9% PCK@20** from a 5-minute data collection session with one ESP32-S3 and one webcam.
| Metric | Before (proxy) | After (camera-supervised) |
|--------|----------------|--------------------------|
| PCK@20 | 0% | **92.9%** |

[**rUv Neural**](v2/crates/ruv-neural/README.md) is a 12-crate Rust ecosystem that extends RuView's signal processing into brain network topology analysis. It transforms neural magnetic field measurements from quantum sensors (NV diamond magnetometers, optically pumped magnetometers) into dynamic connectivity graphs, using minimum cut algorithms to detect cognitive state transitions in real time. The ecosystem includes crates for signal processing (`ruv-neural-signal`), graph construction (`ruv-neural-graph`), HNSW-indexed pattern memory (`ruv-neural-memory`), graph embeddings (`ruv-neural-embed`), cognitive state decoding (`ruv-neural-decoder`), and ESP32/WASM edge targets. Medical and research applications include early neurological disease detection via topology signatures, brain-computer interfaces, clinical neurofeedback, and non-invasive biomedical sensing -- bridging RuView's RF sensing architecture with the emerging field of quantum biomedical diagnostics.

# Archive
Frozen, no-longer-active components of RuView preserved for historical
reference, reproducibility, and load-bearing legacy paths the active
codebase still depends on.
## What lives here
| Path | What it is | Why it's archived | Still load-bearing? |
|------|------------|-------------------|---------------------|
| `v1/` | Original Python implementation of RuView (CSI processing, hardware adapters, services, FastAPI) | Superseded by the Rust workspace at `v2/`; ~810× slower in benchmarks. Kept rather than deleted because the deterministic proof bundle (`v1/data/proof/`) is part of the pre-merge witness verification process per ADR-011 / ADR-028. | **Yes — for the proof bundle only.** Active code lives in `v2/`. |
## What "archived" means
- **Do not add new features here.** New work goes in `v2/`.
- **Do not refactor or modernize the archived code beyond what is
strictly necessary** to keep the load-bearing paths working. The
Python proof bundle is intentionally frozen so that its SHA-256
reproducibility holds across releases (per ADR-028's witness
verification requirement).
- **Bug fixes inside archived code are allowed** when the bug affects a
still-load-bearing path (currently: only the Python proof). All
other "bugs" in archived code are out-of-scope — they are part of
the historical record and any fix would unnecessarily churn the
witness hashes.
- **CI continues to verify the load-bearing paths.**
`.github/workflows/verify-pipeline.yml` runs the Python proof on
every push and PR; if you change anything inside `archive/v1/src/`
or `archive/v1/data/proof/`, expect the determinism check to flag
it.
## Quick reference for the load-bearing paths
```bash
# Run the deterministic Python proof (must print VERDICT: PASS)
python archive/v1/data/proof/verify.py
# Regenerate the expected hash (only if numpy/scipy version legitimately changed)
python archive/v1/data/proof/verify.py --generate-hash
# Run the full Python test suite (legacy, still maintained)
cd archive/v1&& python -m pytest tests/ -x -q
```
## Why we keep `v1/` rather than delete it
1. **Trust kill-switch.** The proof at `v1/data/proof/verify.py` feeds
a known reference signal through the full pipeline and hashes the
output. If the active code's behavior drifts, the hash changes and
CI fails. This is what stops accidental regression in the science
layer of the codebase.
2. **Witness verification.** ADR-028's witness-bundle process bundles
the proof, the rust workspace test results, and firmware hashes
into a tarball recipients can self-verify. Removing v1 would break
that chain.
3. **Historical reference.** ADR-011 documents the "no mocks in
production code" decision; the original violations and their fixes
live in this Python codebase. The ADRs reference these paths.
If the time comes to retire the proof bundle (e.g., a Rust port of
the proof exists and the Python version is no longer canonical), the
right move is a single follow-up that simultaneously: ports the
witness-bundle process, updates `verify-pipeline.yml`, and either
deletes `archive/v1/` or moves it to a separate read-only repository.
That decision belongs in its own ADR.

# RuView Troubleshooting Guide
Known issues and fixes from the rebase-to-upstream branch (upstream #301).
---
## 1. Node not appearing in /api/v1/nodes
**Symptom:** ESP32-S3 node associates with WiFi, LED blinks, but no CSI frames arrive at the server. Node missing from `/api/v1/spatial/nodes`.
**Root cause:** After USB flash, the node enters a limping state where WiFi associates but the UDP CSI sender silently fails. The SoftAP + mDNS stack initializes but the CSI callback never fires.
**Fix:** Power cycle the node (unplug USB, wait 2s, replug). If that doesn't work, send DTR reset via serial: `python -m serial.tools.miniterm --dtr 0 COMx 115200` then Ctrl+C.
**Prevention:** Firmware 0.8.0+ includes a watchdog that detects zero CSI frames for 30s and triggers a software reset automatically. Nodes 1-10 are still on old firmware and lack this recovery (OTA-vs-BLE chicken-and-egg; see issue #6).
---
## 2. Person count stuck at 1
**Symptom:** `estimated_persons` always returns 1 regardless of how many people are in the room.
**Root cause (ADR-044):** Eight converging bugs:
1. `score_to_person_count` had a ceiling of 3
2. `fuse_multi_node_features` used `.max()` instead of sum — N identical readings collapsed to 1
3. Four `.max(1)` clamps forced minimum count to 1 even when absent
4. `field_model.estimate_occupancy` capped at `.min(3)`
5. Normalization saturated (dividing by hardcoded thresholds instead of adaptive p95)
6. No field model auto-calibration — eigenvalue path never activated
7. Vitals-path clamps were asymmetric
8. Tomography produced one blob (CC=1) so dedup gave wrong count
**Fix applied (Waves 1-3):**
- Wave 1 (`9cc5f604`): ceiling 3→10, `.max()` → sum/3 aggregation, softened `.max(1)` clamps
- Wave 2 (`306f1262`): RollingP95 adaptive normalization, field_model 30s auto-calibration, vitals clamp symmetry
- Wave 3 (`c3df375a`+`0d4bfb09`+`6ac70ddf`): CC flood-fill infrastructure, lambda 0.1→5.0, threshold 0.01→0.15, CC>1 gate
**Current state:** `estimated_persons` = 6-8 for 5 bodies (3 humans + 2 dogs). Overcounts because the sum/3 dedup factor is a guess. Tomography still produces one blob (CC=1), so the CC path doesn't activate. Runtime-configurable lambda would help tune without redeployment.
---
## 3. Heart rate / breathing rate jitter
**Symptom:** HR and BR readings jump wildly between frames. BR CV was 23.3%, HR CV was 12.9%.
**Root cause (ADR-045):** 11 ESP32 nodes each compute independent vitals. The server used last-write-wins — whichever node's UDP packet arrived last overwrote the global vitals. At ~20 fps per node, this meant vitals randomly interleaved from different vantage points every 50ms.
**Fix applied (`46fbc061`):** Best-node selection. Each node's vitals are smoothed independently via median filter + EMA. The node with the highest combined `breathing_confidence + heartbeat_confidence` is selected as authoritative. Result: BR CV 23.3% → 12.6%, HR CV 12.9% → 11.6%.
**Known limitation:** The `wifi-densepose-vitals` crate has a superior 4-stage pipeline (bandpass → Hilbert envelope → autocorrelation → peak detection) but is not yet wired into the sensing server. The current `VitalSignDetector` uses a simpler FFT approach with 4 BPM frequency resolution.
---
## 4. Signal quality shows 50% always
**Symptom:** The dashboard signal quality gauge was always stuck at ~50%.
**Root cause:** Signal quality was a hardcoded placeholder value, not derived from actual CSI data.
**Fix applied:** ADR-044 Wave 2 replaced the fake gauge with RollingP95 adaptive normalization. The UI honesty pass (`b2070ab4`) added beta tags to unvalidated metrics, replaced the fake gauge with per-node pill indicators, and surfaced the actual per-node signal data.
---
## 5. Dashboard freezes every 2-4 seconds
**Symptom:** The spatial view and dashboard would freeze, then reconnect, creating a visible stutter every 2-4 seconds.
**Root cause:** The WebSocket broadcast channel's `recv()` returned `Err(Lagged)` when a client fell behind. The server treated this as a fatal error and dropped the connection. The client immediately reconnected, creating a connect/disconnect cycle.
**Fix applied (`581daf4f`):**
- Server: `Lagged` error → `continue` (skip missed frames instead of disconnecting)
- Server: 30s ping/pong keepalive to prevent Caddy proxy idle timeouts
- Result: 154 frames over 8 seconds sustained, zero disconnects

## 6. OTA update crashes at 59%
**Symptom:** OTA firmware update via `/api/v1/firmware/download` progresses to ~59% then the node crashes with `StoreProhibited` on Core 1.
**Root cause:** NimBLE BLE advertising/scanning runs on Core 1. During OTA, the HTTP client also runs on Core 1. BLE and OTA compete for stack space, and the BLE scan callback triggers a memory access violation during the OTA write.
**Fix:**
1. Stop NimBLE advertising and scanning before calling `esp_https_ota_begin()`
2. Increase httpd stack from 4KB to 8KB (`CONFIG_HTTPD_MAX_REQ_HDR_LEN` and task stack)
3. Resume BLE after OTA completes or fails
**Caveat:** Nodes running old firmware (1-10) can't receive this fix via OTA because the crash happens during the OTA itself. These nodes must be USB-flashed with firmware 0.8.0+ first, then future OTA updates will work. Node 11 was USB-flashed with the watchdog firmware and can receive OTA updates.
---
## 7. Can't SSH to babycube via LAN
**Symptom:** `ssh thyhack@10.0.10.10` hangs at banner exchange. Ping works, TCP port 22 is open, but SSH never completes the handshake.
**Workaround:** Use the Tailscale IP instead:
```
ssh thyhack@100.90.238.87
```
**Not the cause:** CrowdSec. The 10.0.0.0/8 range is whitelisted in CrowdSec (`cscli decisions list` shows no active decisions for LAN IPs). The banner hang occurs before any authentication attempt, so it's not a firewall block.
**Suspected cause:** Unknown. Possibly MTU/fragmentation issue on the LAN segment, or a network stack bug in the babycube's NIC driver. The Tailscale overlay network (WireGuard UDP) bypasses whatever is causing the LAN TCP issue.
---
## 8. Right USB-C port doesn't work on some ESP32-S3 boards
**Symptom:** Plugging into the right USB-C port (when facing the board with USB-C toward you) shows no serial device on the host.
**Fix:** Use the left USB-C port. On most ESP32-S3-DevKitC boards, the left port is the USB-to-UART bridge (CP2102/CH340) used for flashing and serial monitor. The right port is the native USB (USB-JTAG) which requires different drivers and isn't used by the RuView firmware.

# ADR-044: Geospatial Satellite Integration
## Status
Accepted
## Context
RuView generates real-time 3D point clouds from camera + WiFi CSI, but these exist in a local coordinate frame with no geographic reference. Integrating free satellite imagery, terrain elevation, and map data provides environmental context that enables the ruOS brain to reason about the physical world beyond the room.
## Decision
### Data Sources (all free, no API keys)
| Source | Data | Resolution | Update | Format |
|--------|------|-----------|--------|--------|
| EOX Sentinel-2 Cloudless | Satellite tiles | 10m | Static mosaic | XYZ/JPEG |
| SRTM GL1 (NASA) | Elevation/DEM | 30m (1-arcsec) | Static | Binary HGT |
| Overpass API (OSM) | Buildings, roads | Vector | Real-time | JSON |
| ip-api.com | IP geolocation | ~1km | Per-request | JSON |
| Sentinel-2 STAC | Temporal satellite | 10m | Every 5 days | COG/STAC |
| Open Meteo | Weather | Point | Hourly | JSON |
### Architecture
Pure Rust implementation in `wifi-densepose-geo` crate. No GDAL/PROJ/GEOS — coordinate transforms implemented directly (~250 LOC). Tile caching on disk at `~/.local/share/ruview/geo-cache/`.
### Coordinate System
- WGS84 for geographic coordinates
- ENU (East-North-Up) as the bridge between local sensor frame and world
- Local sensor frame: camera origin, +Z forward, +Y up
### Temporal Awareness
Nightly scheduled fetch of Sentinel-2 latest imagery + OSM diffs + weather.
Changes detected via image comparison and stored as brain memories for
contrastive learning.
### Brain Integration
Geospatial context stored as brain memories:
- `spatial-geo`: location, elevation, nearby landmarks
- `spatial-change`: detected changes in satellite/OSM data
- `spatial-weather`: current conditions + forecast
- `spatial-season`: vegetation index, snow cover, seasonal patterns
- `spatial-local`: hyperlocal web context from Common Crawl WET
### Extended Data Sources (via ruvector WET/Common Crawl)
| Source | Data | Use |
|--------|------|-----|
| Common Crawl WET | Web text near location | Local business info, reviews, events |
| Wikidata | Structured knowledge | Building names, POI descriptions |
| NASA FIRMS | Active fire (3-hour) | Safety alerts |
| USGS Earthquakes | Seismic events | Safety context |
| OpenAQ | Air quality (PM2.5) | Environmental health |
| Overture Maps | Building footprints (Meta/MS) | Higher quality than OSM |
The ruvector brain server has existing `web_ingest` + Common Crawl support.
WET files filtered by geographic URL patterns provide hyperlocal context.
## Consequences
### Positive
- Agent gains environmental awareness beyond the room
- Temporal data enables seasonal calibration of CSI sensing
- Change detection finds construction, vegetation, weather effects
- All data sources are genuinely free with no API keys
### Negative
- Initial data fetch requires internet (~2MB tiles + ~25MB DEM)
- Cached data becomes stale (mitigated by nightly refresh)
- IP geolocation has ~1km accuracy (mitigated by manual override)

## Context
The wifi-densepose project has two hardware components that need to work as an integrated sensing pipeline:
1. **ESP32-S3** (COM9 / 192.168.1.105) — Captures WiFi CSI at 100 Hz, runs dual-core DSP pipeline (phase extraction, subcarrier selection, breathing/heart rate estimation, presence/fall detection), and sends ADR-018 binary frames via UDP.
2. **Cognitum Seed** (USB / 169.254.42.1 / 192.168.1.109) — A Pi Zero 2 W edge intelligence appliance running firmware v0.8.1. It provides:
- **RVF vector store** — Append-only binary format with content-addressed IDs, kNN queries (cosine/L2/dot), and kNN graph with boundary analysis
- **Witness chain** — SHA-256 tamper-evident audit trail for every write operation
- **Ed25519 custody** — Device-bound keypair for cryptographic attestation
- **Sensor pipeline** — 5 sensors (reed switch, PIR, vibration, ADS1115 4-ch ADC, BME280), 13 drift detectors, anti-spoofing
- **Cognitive container** — Spectral graph analysis with Stoer-Wagner min-cut fragility scoring
- **MCP proxy** — 114 tools via JSON-RPC 2.0 for AI assistant integration
- **Thermal governor** — DVFS management with zone-based frequency scaling
- **Temporal coherence** — Phase boundary detection across vector store evolution
- **Swarm sync** — Epoch-based delta replication between peers
- **Reflex rules** — 3 rules (fragility alarm, drift cutoff, HD anomaly indicator)
- **98 HTTPS API endpoints** with per-client bearer token authentication
### Current State

| ESP32 → Seed pipeline | **Validated** | Bridge on host laptop, UDP 5006 → HTTPS ingest (see Validation Results) |
### Gap Analysis (from Arena Physica research)
Arena Physica's approach (Heaviside-0 forward model, Marconi-0 inverse diffusion) demonstrates that neural surrogates for Maxwell's equations are production-viable. Our research identified that:
1. **Physics-informed intermediate supervision** — Evaluating pipeline stages independently catches failures that end-to-end metrics miss
2. **Vector embeddings for EM fields** — Storing CSI features as vectors enables similarity search for environment fingerprinting and anomaly detection
3. **Witness chain for sensing integrity** — Tamper-evident audit trails are critical for healthcare/safety applications (fall detection, vital signs)
4. **Edge compute for inference** — Pi Zero 2 W can run ~2.5M parameter models at 10+ Hz with INT8 quantization
### Problem
There is no pipeline connecting ESP32 CSI sensing to the Cognitum Seed's vector store. The ESP32 sends raw CSI frames to the Rust sensing-server (typically running on a laptop/desktop), but cannot leverage the Seed's:
- Persistent vector storage with kNN search
- Cryptographic witness chain for data integrity
- Cognitive container for structural analysis
- Sensor fusion with environmental sensors (BME280 temperature/humidity, PIR motion)
- Swarm sync for multi-Seed deployments
## Decision
Build a three-stage pipeline connecting ESP32 CSI capture to Cognitum Seed RVF storage:

### Stage 1: ESP32 Feature Vector Extraction
The ESP32 edge processing pipeline (Core 1) already computes all signals needed. We add a compact 8-dimensional feature vector extracted from the existing DSP outputs:
| Dimension | Feature | Source | Range |
|-----------|---------|--------|-------|
| 0 | Presence score | `s_presence_score / 10.0` (clamped) | 0.01.0 |
| 1 | Motion energy | `s_motion_energy / 10.0` (clamped) | 0.01.0 |
| 2 | Breathing rate | `s_breathing_bpm / 30.0` (clamped) | 0.01.0 |
| 3 | Heart rate | `s_heartrate_bpm / 120.0` (clamped) | 0.01.0 |
| 4 | Phase variance (mean) | Top-K subcarrier Welford variance mean | 0.01.0 |
| 5 | Person count | `n_active_persons / 4.0` (clamped) | 0.01.0 |
| 6 | Fall detected | Binary: 1.0 if `s_fall_detected`, else 0.0 | 0.0 or 1.0 |
| 7 | RSSI (normalized) | `(s_latest_rssi + 100) / 100` (clamped) | 0.01.0 |
This maps directly to the Seed's store dimension of 8, enabling kNN queries like "find the 10 most similar sensing states to the current one."
**Packet format** (magic `0xC5110003`, defined as `edge_feature_pkt_t` in `edge_processing.h`):
```c
typedef struct __attribute__((packed)) {
uint32_t magic; // EDGE_FEATURE_MAGIC = 0xC5110003
uint8_t node_id; // ESP32 node identifier
uint8_t reserved; // alignment padding
uint16_t seq; // sequence number
int64_t timestamp_us; // microseconds since boot
float features[8]; // 8-dim normalized feature vector (32 bytes)
} edge_feature_pkt_t; // Total: 48 bytes (static_assert enforced)
```
**Transmission rate:** 1 Hz (one feature vector per second, aggregated from 100 Hz CSI). This keeps UDP bandwidth under 50 bytes/s per node and avoids overwhelming the Seed's vector store.
### Stage 2: Seed-Side RVF Ingest
A lightweight Rust service on the Seed (or a Python bridge script) listens for feature packets on UDP port 5006 and ingests them via the Seed's REST API:
```bash
# Ingest a feature vector with metadata
curl -sk -X POST https://169.254.42.1:8443/api/v1/store/ingest \
-H "Authorization: Bearer $TOKEN" \
-H "Content-Type: application/json" \
-d '{
"vectors": [[0, [0.85, 0.3, 0.52, 0.65, 0.4, 0.78, 0.1, -0.45]]],
"metadata": {
"node_id": 1,
"type": "csi_feature",
"timestamp": 1775166970
}
}'
```
**Batching:** Accumulate 10 vectors (10 seconds) per ingest call to reduce HTTP overhead (`--batch-size 10` default in `seed_csi_bridge.py`; also supports time-based flushing via `--flush-interval`). At 1 vector/second per node, a 4-node mesh generates 14,400 vectors/hour (345,600/day). Daily compaction is required to stay within the Seed's 100K vector working set (see Storage Budget).
**Witness chain:** Each ingest automatically appends a witness entry, providing a tamper-evident record of all sensing data. The epoch increments monotonically, and the SHA-256 chain can be verified at any time via `POST /api/v1/witness/verify`.
### Stage 3: Cognitive Analysis & Sensor Fusion
Once CSI feature vectors are in the RVF store, the Seed's existing subsystems activate:
1. **kNN Graph** — Rebuilt every 10 seconds. Similar sensing states cluster together. Anomalous states (intruder, fall, unusual breathing) appear as outliers.
2. **Boundary Analysis** — Stoer-Wagner min-cut computes a fragility score (0.01.0). High fragility indicates the vector space is splitting — a regime change in the environment (door opened, person entered/left, HVAC state change).
3. **Temporal Coherence** — Phase boundary detection across the vector store timeline identifies when the environment transitions between states (occupied → empty, day → night, normal → abnormal).
4. **Reflex Rules** — Three pre-configured rules fire automatically:
- `fragility_alarm` (threshold 0.3) → relay actuator for presence alert
- `drift_cutoff` (threshold 1.0) → cutoff when sensor drift detected
- `hd_anomaly_indicator` (threshold 200) → PWM brightness for anomaly severity
5. **Sensor Fusion** — The Seed's BME280 (temperature/humidity/pressure) and PIR sensor provide environmental ground truth that correlates with CSI features:
- PIR motion validates CSI presence detection
- Temperature changes correlate with occupancy
- Humidity changes correlate with breathing detection fidelity
6. **MCP Integration** — AI assistants can query the full pipeline via the 114-tool MCP proxy:
```json
{"method": "tools/call", "params": {"name": "seed.memory.query", "arguments": {"vector": [0.8, 0.5, 0.4, 0.6, 0.3, 0.7, 0.1, -0.3], "k": 5}}}
```
### ESP32 Provisioning
The ESP32's existing NVS provisioning system supports configuring the Seed as the target:
```bash
python firmware/esp32-csi-node/provision.py \
--port COM9 \
--target-ip 192.168.1.20 \
--target-port 5006 \
--node-id 1
```
Note: `--target-ip` is the host laptop (192.168.1.20), not the Seed IP, because the bridge runs on the host and forwards to the Seed via HTTPS (see Known Issue 4).
No firmware recompilation needed — the `stream_sender` module reads target IP/port from NVS at boot.
### Data Flow Rates
| Path | Rate | Size | Bandwidth |
|------|------|------|-----------|
| CSI capture → ring buffer | 100 Hz | ~400 B | 40 KB/s (internal) |
| Edge DSP → sensing-server | 100 Hz | ~200 B | 20 KB/s (existing) |
| Edge DSP → Seed features | 1 Hz | 48 B | 48 B/s (new) |
| Seed ingest (batched) | 0.1 Hz | ~500 B | 50 B/s (HTTP) |
| Seed kNN graph rebuild | 0.1 Hz | internal | — |
| Seed witness chain | per batch | 32 B hash | — |
### Storage Budget
| Timeframe | Vectors/node | 4 nodes | RVF size | RAM |
|-----------|-------------|---------|----------|-----|
| 1 hour | 3,600 | 14,400 | ~580 KB | ~6 MB |
| 24 hours | 86,400 | 345,600 | ~14 MB | ~140 MB |
| 7 days | 604,800 | 2,419,200 | ~97 MB | exceeds |
**Compaction policy:** Run `POST /api/v1/store/compact` daily at 03:00, retaining only the last 24 hours of vectors. Archive older vectors to USB drive via `POST /api/v1/store/export` before compaction.
**Dimension reduction:** For deployments exceeding 100K vectors, reduce feature extraction rate to 0.1 Hz (one vector per 10 seconds) or increase compaction frequency.
## Validation Results
**Live hardware test performed 2026-04-02.**
### Hardware Under Test
| Component | Port | IP | Firmware | WiFi | RSSI |
|-----------|------|----|----------|------|------|
| ESP32-S3 (8MB) | COM9 | 192.168.1.105 | v0.5.2 | ruv.net (ch 5) | -34 dBm |
| Cognitum Seed | USB | 169.254.42.1 / 192.168.1.109 | v0.8.1 | ruv.net | — |
| Host laptop | — | 192.168.1.20 | — | ruv.net | — |
Seed device_id: `ecaf97dd-fc90-4b0e-b0e7-e9f896b9fbb6`. Pairing token issued to `wifi-densepose-claude`.
### Pipeline Validated
1. **UDP streaming** -- 211 packets captured in 15 seconds:
- 196 raw CSI frames (magic `0xC5110001`)
- 15 vitals frames (magic `0xC5110002`)
2. **Bridge pipeline** -- 20 vitals packets (`0xC5110002`) parsed, converted to 8-dim feature vectors via the bridge's `parse_vitals_packet()` fallback path, ingested in 4 batches of 5 vectors each (`--batch-size 5`). The native `0xC5110003` feature packet path is implemented in firmware but was not exercised in this validation run (firmware was v0.5.2; the `send_feature_vector()` addition requires a reflash).
3. **RVF ingest** -- All 20 vectors accepted by Seed. Epochs advanced 88 to 91. Witness chain verified valid (193 entries, SHA-256 chain intact).
4. **Seed sensors** -- BME280, PIR, reed switch, ADS1115, vibration sensor all present and healthy.
### Live Vital Signs Captured
| Metric | Observed Range | Expected | Notes |
|--------|---------------|----------|-------|
| Presence score | 1.41 -- 14.92 | 0.0 -- 1.0 | **Needs normalization** (see Known Issues) |
| Motion energy | 1.41 -- 14.92 | 0.0 -- 1.0 | Same raw value as presence score |
| Breathing rate | 19.8 -- 33.5 BPM | 12 -- 25 BPM | Plausible but slightly high |
| Heart rate | 75.3 -- 99.1 BPM | 60 -- 100 BPM | Plausible range |
| RSSI | -43 to -72 dBm | -30 to -80 dBm | Normal |
| Fall detected | No | — | Correct (no falls occurred) |
| n_persons | 4 | 1 | **Miscalibrated** (see Known Issues) |
### Known Issues Found
1. **`presence_score` exceeds 1.0 in vitals packets** -- Raw values range 1.41 to 14.92 in the vitals packet (`0xC5110002`). The bridge's vitals-to-feature conversion clamps to 1.0 for dim 0 and divides by 10.0 for dim 1 (`motion_energy / 10.0`), but dim 0 clamps without scaling. **Note:** The firmware's native feature vector (`0xC5110003`) already normalizes correctly by dividing `s_presence_score` by 10.0 (see `edge_processing.c` line 657). This issue only affects the vitals-packet fallback path in the bridge.
2. **`n_persons = 4` with 1 person present** -- The multi-person counting algorithm is miscalibrated for single-occupancy scenarios. The per-node state pipeline (ADR-068) may mitigate this when the baseline is properly trained, but the raw edge count is unreliable.
3. **Content-addressed vector IDs cause deduplication** -- Similar feature vectors hash to the same ID, causing the Seed to silently drop duplicates. **Fixed in bridge:** `seed_csi_bridge.py` now uses `_make_vector_id()` which generates a SHA-256 hash of `node_id:timestamp_us:seq_counter`, producing unique 32-bit IDs. This was observed during validation and fixed before the final test run.
4. **Bridge runs on host, not Seed** -- The ESP32 target IP must be the host laptop (192.168.1.20), not the Seed IP. The bridge script on the host forwards to the Seed via HTTPS. This adds a hop but avoids running a UDP listener on the Pi Zero 2 W.
5. **PIR GPIO read returned 404** -- `GET /api/v1/sensor/gpio/read?pin=6` returned 404. The PIR endpoint may require a different pin number or endpoint format. Ground-truth validation against PIR is deferred to Phase 3.
## Implementation Plan
### Phase 1: ESP32 Feature Extraction (firmware change) -- DONE
Implemented as `send_feature_vector()` in `edge_processing.c` (lines 644-699) and `edge_feature_pkt_t` in `edge_processing.h` (lines 112-124). The function reads from static globals (`s_presence_score`, `s_motion_energy`, `s_breathing_bpm`, `s_heartrate_bpm`, subcarrier Welford variance, person tracker, fall flag, RSSI) and normalizes each dimension to 0.0-1.0 with clamping.
Called at the same 1 Hz cadence as `send_vitals_packet()` in Step 13 of the edge processing pipeline (line 855). The compressed frame magic was reassigned from `0xC5110003` to `0xC5110005` to free up `0xC5110003` for feature vectors (`EDGE_COMPRESSED_MAGIC` in `edge_processing.h` line 29).
### Phase 2: Seed Ingest Bridge (Python script on host) -- DONE
Implemented as `scripts/seed_csi_bridge.py`. The bridge:
1. Listens on UDP port 5006 (configurable via `--udp-port`)
2. Accepts all three packet formats: `0xC5110003` (ADR-069 features), `0xC5110002` (vitals, converted to 8-dim), and `0xC5110001` (raw CSI, minimal features)
3. Generates unique vector IDs via SHA-256 hash of `node_id:timestamp:seq` (avoids content-addressed deduplication -- see Known Issue 3)
4. Batches vectors (default 10, configurable via `--batch-size`) with time-based flush fallback (`--flush-interval`)
5. POSTs to Seed's `/api/v1/store/ingest` with bearer token
6. Supports `--validate` mode (kNN query + PIR comparison after each batch)
7. Supports `--stats` mode (print Seed status, boundary, coherence, graph)
8. Supports `--compact` mode (trigger store compaction)
### Phase 3: Validation & Ground Truth -- BLOCKED
Use the Seed's PIR sensor as ground truth for presence detection:
1. Query PIR state: `GET /api/v1/sensor/gpio/read?pin=6`
2. Compare with CSI presence score (feature dim 0)
3. Log agreement/disagreement rate
4. Use kNN to find historical vectors matching current PIR state → validate CSI accuracy
**Status:** The bridge implements `--validate` mode with PIR comparison (see `_run_validation()` in `seed_csi_bridge.py`). However, the PIR endpoint returned 404 during validation (Known Issue 5). This phase is blocked until the correct PIR API endpoint is identified.
### Phase 4: Multi-Node Mesh (addresses #348)
Deploy 3 ESP32 nodes, each sending feature vectors to the bridge host (which forwards to the Seed):
- Node 1 (lobby): `--node-id 1 --target-ip 192.168.1.20 --target-port 5006`
- Node 2 (hallway): `--node-id 2 --target-ip 192.168.1.20 --target-port 5006`
- Node 3 (room): `--node-id 3 --target-ip 192.168.1.20 --target-port 5006`
All nodes target the host laptop (192.168.1.20) where the bridge script runs. The bridge batches and forwards all nodes' vectors to the Seed via HTTPS. The Seed's kNN graph naturally clusters vectors by node and by sensing state. Cross-node analysis via boundary fragility detects when a person moves between zones.
## Security Considerations
1. **Bearer token** — All write operations require the pairing token. Token stored as SHA-256 hash on device.
2. **TLS** — All API calls over HTTPS (port 8443) with device-provisioned CA certificate.
3. **Witness chain** — Every ingest is cryptographically chained. Tampering detection via `POST /api/v1/witness/verify`.
4. **Ed25519 attestation** — Device identity bound to hardware keypair. Attestation includes epoch, vector count, and witness head.
5. **Anti-spoofing** — Sensor pipeline has entropy-based spoofing detection (min 0.5 bits entropy, streak threshold 3).
6. **USB-only pairing** — Pairing window can only be opened from USB interface (169.254.42.1), not from WiFi.
## Hardware Bill of Materials

## Risks
| Risk | Likelihood | Impact | Mitigation |
|------|-----------|--------|------------|
| Pi Zero thermal throttling at sustained ingest | Medium | Performance degrades | Thermal governor already manages DVFS; 1 Hz ingest is minimal load |
| WiFi congestion with ESP32 CSI + UDP | Low | Lost packets | Feature vectors are 48 bytes at 1 Hz; negligible vs CSI traffic |
| RVF store exceeds RAM at high vector count | Medium | OOM | Compaction policy + dimension reduction + daily export |
| Bearer token exposure | Low | Unauthorized writes | TLS encryption + USB-only pairing + token hashing |
| ESP32 NVS corruption | Low | Config lost | NVS is wear-leveled flash with CRC; re-provision via USB |
## Consequences
### Positive
- ESP32 CSI features become persistent, searchable, and cryptographically attested
- kNN similarity search enables environment fingerprinting and anomaly detection
- PIR + BME280 provide ground truth for CSI validation
- MCP proxy enables AI assistants to query sensing state directly
- Witness chain provides audit trail for healthcare/safety applications
- Architecture aligns with Arena Physica's insight: store embeddings, not raw signals
### Negative
- Additional firmware packet type (48 bytes, trivial)
- Bridge script needed on Seed or host machine
- Daily compaction required for long-running deployments
- Bearer token must be managed (stored securely, rotated if compromised)
### Neutral
- Existing sensing-server pipeline unchanged (ESP32 still sends to port 5005)
- Seed's existing sensors continue operating independently
- Target IP/port configurable via NVS provisioning (no recompilation for deployment changes)
- Firmware recompilation needed once to add `send_feature_vector()` (Phase 1), but subsequent node deployments only need provisioning

# ADR-070: Self-Supervised Pretraining from Live ESP32 CSI + Cognitum Seed
| Field | Value |
|------------|----------------------------------------------------------|
| Status | Accepted |
| Date | 2026-04-02 |
| Authors | rUv, claude-flow |
| Drivers | README limitation "No pre-trained model weights provided"|
| Related | ADR-069 (Cognitum Seed pipeline), ADR-027 (MERIDIAN), ADR-024 (AETHER contrastive), ADR-015 (MM-Fi dataset) |
## Context
The README lists "No pre-trained model weights are provided; training from scratch is required" as a known limitation. Users must collect their own CSI dataset and train from scratch, which is a significant barrier to adoption.
We now have the infrastructure to generate pre-trained weights directly from live hardware:
- **2 ESP32-S3 nodes** (COM8 node_id=2 at 192.168.1.104, COM9 node_id=1 at 192.168.1.105) streaming CSI + vitals + 8-dim feature vectors at 1 Hz each
- **Cognitum Seed** (Pi Zero 2 W) with RVF vector store, kNN search, witness chain, and environmental sensors (BME280, PIR, vibration)
- **Recording API** in sensing-server (`POST /api/v1/recording/start`) that saves CSI frames to `.csi.jsonl`
- **Self-supervised training** via `rapid_adapt.rs` (contrastive TTT + entropy minimization)
- **AETHER contrastive embeddings** (ADR-024) for environment-independent representations
### Why Self-Supervised?
No cameras or labels are needed. The system learns from:
1. **Temporal coherence** — Frames close in time should have similar embeddings (positive pairs), frames far apart should differ (negative pairs)
2. **Multi-node consistency** — The same person seen from 2 nodes should produce correlated features, different people should produce decorrelated features
3. **Cognitum Seed ground truth** — PIR sensor, BME280 environment changes, and kNN cluster transitions provide weak supervision without human labeling
4. **Physical constraints** — Breathing 6-30 BPM, heart rate 40-150 BPM, person count 0-4, RSSI physics
## Decision
Implement a 4-phase pretraining pipeline that collects CSI from 2 ESP32 nodes, stores feature vectors in the Cognitum Seed, and produces distributable pre-trained weights.
### Phase 1: Data Collection (30 min)
Capture labeled scenarios using the sensing-server recording API and Cognitum Seed:
| Scenario | Duration | Label | Activity |
|----------|----------|-------|----------|
| Empty room | 5 min | `empty` | No one present, establish baseline |
| 1 person stationary | 5 min | `1p-still` | Sit at desk, normal breathing |
| 1 person walking | 5 min | `1p-walk` | Walk around room, varied paths |
| 1 person varied | 5 min | `1p-varied` | Stand, sit, wave arms, turn |
| 2 people | 5 min | `2p` | Both moving in room |
| Transitions | 5 min | `transitions` | Enter/exit room, appear/disappear |
**Data rate per scenario:**
- 2 nodes × 100 Hz CSI = 200 frames/sec = 60,000 frames per 5 min
- 2 nodes × 1 Hz features = 2 vectors/sec = 600 vectors per 5 min
- Total: 360,000 CSI frames + 3,600 feature vectors per collection run
**Cognitum Seed role:**
- Stores all feature vectors with witness chain attestation
- PIR sensor provides binary presence ground truth
- BME280 tracks environmental conditions during collection
- kNN graph clusters naturally emerge from the vector distribution
### Phase 2: Contrastive Pretraining
Train a contrastive encoder on the collected CSI data:
```
Input: Raw CSI frame (128 subcarriers × 2 I/Q = 256 features)
TCN temporal encoder (3 layers, kernel=7)
Projection head → 128-dim embedding
Contrastive loss (InfoNCE):
positive: frames within 0.5s window from same node
negative: frames >5s apart or from different scenario
cross-node positive: same timestamp, different node
```
**Self-supervised signals:**
- Temporal adjacency (frames within 500ms = positive pair)
- Cross-node agreement (same person seen from 2 viewpoints)
- PIR consistency (embedding should cluster by PIR state)
- Scenario boundary (embeddings should shift at label transitions)
### Phase 3: Downstream Head Training
Attach lightweight heads for each task:
| Head | Architecture | Output | Supervision |
|------|-------------|--------|-------------|
| Presence | Linear(128→1) + sigmoid | 0.0-1.0 | PIR sensor (free) |
| Person count | Linear(128→4) + softmax | 0-3 people | Scenario labels |
| Activity | Linear(128→4) + softmax | still/walk/varied/empty | Scenario labels |
| Vital signs | Linear(128→2) | BR, HR (BPM) | ESP32 edge vitals |
### Phase 4: Package & Distribute
Produce distributable artifacts:
| Artifact | Format | Size | Description |
|----------|--------|------|-------------|
| `pretrained-encoder.onnx` | ONNX | ~2 MB | Contrastive encoder (TCN backbone) |
| `pretrained-heads.onnx` | ONNX | ~100 KB | Task-specific heads |
| `pretrained.rvf` | RVF | ~500 KB | RuVector format with metadata |
| `room-profiles.json` | JSON | ~10 KB | Environment calibration profiles |
| `collection-witness.json` | JSON | ~5 KB | Seed witness chain attestation proving data provenance |
Include in GitHub release alongside firmware binaries. Users download and run:
```bash
# Use pre-trained model (no training needed)
cargo run -p wifi-densepose-sensing-server -- --model pretrained.rvf --http-port 3000
```

## Data Collection Protocol
### Step 1: Start Seed ingest (background)
```bash
export SEED_TOKEN="your-token"
python scripts/seed_csi_bridge.py \
--seed-url https://169.254.42.1:8443 --token "$SEED_TOKEN" \
--udp-port 5006 --batch-size 10 --validate &
```
### Step 2: Start sensing-server with recording
```bash
cargo run -p wifi-densepose-sensing-server -- \
--source esp32 --udp-port 5006 --http-port 3000
```
### Step 3: Record each scenario
```bash
# Empty room (leave room for 5 min)
curl -X POST http://localhost:3000/api/v1/recording/start \
-H 'Content-Type: application/json' \
-d '{"session_name":"pretrain-empty","label":"empty","duration_secs":300}'
# 1 person stationary (sit at desk for 5 min)
curl -X POST http://localhost:3000/api/v1/recording/start \
-d '{"session_name":"pretrain-1p-still","label":"1p-still","duration_secs":300}'
# ... repeat for each scenario
```
### Step 4: Verify with Seed
```bash
python scripts/seed_csi_bridge.py --token "$SEED_TOKEN" --stats
# Should show 3,600+ vectors from the collection run
```
## Risks
| Risk | Likelihood | Impact | Mitigation |
|------|-----------|--------|------------|
| 2 nodes insufficient for spatial diversity | Medium | Lower pretraining quality | Place nodes 3-5m apart at different heights |
| PIR sensor has limited range | Low | Weak presence labels | BME280 temp changes + kNN clusters as backup |
| Contrastive pretraining collapses | Low | Useless embeddings | Temperature scheduling, hard negative mining |
| Model too large for ESP32 inference | N/A | N/A | Inference on host/Seed, not on ESP32 |
| Room-specific overfitting | Medium | Poor generalization | MERIDIAN domain randomization (ADR-027), LoRA adaptation |
## Consequences
### Positive
- Users get working model out of the box — no training needed
- Witness chain proves data provenance (when/where/which hardware)
- Pre-trained encoder transfers to new environments via LoRA fine-tuning
- Removes the #1 adoption barrier from the README
### Negative
- 30 min of manual data collection per pretraining run
- Pre-trained weights are room-specific without adaptation
- ONNX runtime dependency for inference

# ADR-071: ruvllm Training Pipeline for CSI Sensing Models
- **Status**: Proposed
- **Date**: 2026-04-02
- **Deciders**: ruv
- **Relates to**: ADR-069 (Cognitum Seed CSI Pipeline), ADR-070 (Self-Supervised Pretraining), ADR-024 (Contrastive CSI Embedding / AETHER), ADR-016 (RuVector Training Pipeline)
## Context
The WiFi-DensePose project needs a training pipeline to convert collected CSI data
(`.csi.jsonl` frames from ESP32 nodes) into deployable models for presence detection,
activity classification, and vital sign estimation.
Previous ADRs established the data collection protocol (ADR-070) and Cognitum Seed
inference target (ADR-069). What was missing was the actual training, refinement,
quantization, and export pipeline connecting raw CSI recordings to deployable models.
### Why ruvllm instead of PyTorch

The ruvllm package (`@ruvector/ruvllm` v2.5.4) provides the complete training
lifecycle in a single dependency: contrastive pretraining, task head training,
LoRA refinement, EWC consolidation, quantization, and SafeTensors/RVF export.
No Python dependency means the entire pipeline runs on the same Node.js runtime
as the Cognitum Seed inference engine.
## Decision
Use ruvllm's `ContrastiveTrainer`, `TrainingPipeline`, `LoraAdapter`, `EwcManager`,
`SafeTensorsWriter`, and `ModelExporter` for the complete CSI model training lifecycle.
### Training Phases
The pipeline executes five sequential phases:
#### Phase 1: Contrastive Pretraining
Learns an embedding space where temporally and spatially similar CSI states are close
and dissimilar states are far apart.
- **Encoder architecture**: 8-dim CSI feature vector -> 64-dim hidden (ReLU) -> 128-dim embedding (L2-normalized)
- **Loss functions**: Triplet loss (margin=0.3) + InfoNCE (temperature=0.07)
- **Triplet strategies**:
- Temporal positive: frames within 1 second (same environment state)
- Temporal negative: frames >30 seconds apart (different state)
- Cross-node positive: same timestamp from different ESP32 nodes (same person, different viewpoint)
- Cross-node negative: different timestamp + different node
- Hard negatives: frames near motion energy transition boundaries
- **Hyperparameters**: 20 epochs, batch size 32, hard negative ratio 0.7
- **Implementation**: `ContrastiveTrainer.addTriplet()` + `.train()`
#### Phase 2: Task Head Training
Trains supervised heads on top of the frozen embedding for specific sensing tasks.
- **Presence head**: 128 -> 1 (sigmoid), threshold at presence_score > 0.3
- **Activity head**: 128 -> 3 (softmax: still/moving/empty), derived from motion_energy thresholds
- **Vitals head**: 128 -> 2 (linear: breathing BPM, heart rate BPM), normalized targets
- **Implementation**: `TrainingPipeline.addData()` + `.train()` with cosine LR scheduler,
early stopping (patience=5), and quality-weighted MSE loss
#### Phase 3: LoRA Refinement
Per-node LoRA adapters for room-specific adaptation without forgetting the base model.
- **Configuration**: rank=4, alpha=8, dropout=0.1
- **Per-node training**: Each ESP32 node gets its own LoRA adapter trained on
node-specific data with reduced learning rate (0.5x base)
- **Implementation**: `LoraManager.create()` for each node, `TrainingPipeline` with
`LoraAdapter` passed to constructor
#### Phase 4: Quantization (TurboQuant)
Reduces model size for edge deployment with minimal quality loss.
| Bit Width | Compression | Typical RMSE | Target Device |
|-----------|-------------|-------------|---------------|
| 8-bit | 4x | <0.001 | Cognitum Seed (Pi Zero) |
| 4-bit | 8x | <0.01 | Standard edge inference |
| 2-bit | 16x | <0.05 | ESP32-S3 feature extraction |
- **Method**: Uniform affine quantization with scale/zero-point per tensor
- **Quality validation**: RMSE between original fp32 and dequantized weights
#### Phase 5: EWC Consolidation
Elastic Weight Consolidation prevents catastrophic forgetting when the model
is later fine-tuned on new room data or updated CSI conditions.
- **Fisher information**: Computed from training data gradients
- **Lambda**: 2000 (base), 3000 (per-node)
- **Tasks registered**: Base pretraining + one per ESP32 node
- **Implementation**: `EwcManager.registerTask()` for each training phase

## Consequences
### Positive
- **Zero Python dependency**: The entire training and inference pipeline runs on
Node.js, eliminating Python/CUDA/pip dependency management on training and
deployment targets.
- **Integrated lifecycle**: Contrastive pretraining, task heads, LoRA refinement,
EWC consolidation, and quantization in a single script using one library.
- **Edge-first**: 2-bit quantization enables running the encoder on ESP32-S3.
4-bit quantization fits comfortably on Cognitum Seed Pi Zero.
- **Continual learning**: EWC protection means the model can be updated with new
room data without losing previously learned patterns.
- **Per-node adaptation**: LoRA adapters allow room-specific fine-tuning with
minimal storage overhead (rank-4 adapter ~2KB per node).
- **HuggingFace compatibility**: SafeTensors export enables sharing models on the
HuggingFace Hub and loading in other frameworks.
- **Reproducibility**: Seeded encoder initialization and deterministic data pipeline
ensure reproducible training runs.
### Negative
- **No GPU acceleration**: ruvllm's JS training loop does not use GPU compute.
For the small model sizes in CSI sensing (8->64->128), this is acceptable
(~seconds on M4 Pro), but would not scale to large vision models.
- **Simplified backpropagation**: The LoRA backward pass and contrastive training
use approximate gradient updates rather than full automatic differentiation.
Sufficient for the target model sizes but not equivalent to PyTorch autograd.
- **Quantization is post-training only**: No quantization-aware training (QAT).
For 4-bit and 8-bit this produces acceptable quality loss; 2-bit may need
QAT in future if quality degrades.
### Risks
- **Quality ceiling**: The simplified training may produce lower accuracy than a
PyTorch-trained equivalent. Mitigated by: (a) the model is small enough that
the training loop converges quickly, (b) SONA adaptation can compensate at
inference time, (c) we can switch to PyTorch for training only if needed
while keeping ruvllm for inference.
- **ruvllm API stability**: The library is at v2.5.4 with active development.
Mitigated by vendoring the package in `vendor/ruvector/npm/packages/ruvllm/`.

## Camera-Free Supervision
### Motivation
Traditional WiFi-based pose estimation (WiFlow, Person-in-WiFi) requires camera-supervised
training: a camera captures ground-truth poses during CSI collection, and the model learns
to map CSI to those poses. This creates a deployment paradox — the camera is needed for
training but the whole point of WiFi sensing is to avoid cameras.
The camera-free pipeline (`scripts/train-camera-free.js`) replaces camera supervision with
10 sensor signals from the Cognitum Seed and 2 ESP32 nodes, generating weak labels through
sensor fusion.
### 10 Supervision Signals (No Camera)
| # | Signal | Source | Provides |
|---|--------|--------|----------|
| 1 | PIR sensor | Seed GPIO 6 | Binary presence ground truth |
| 2 | BME280 temperature | Seed I2C 0x76 | Occupancy proxy (temp rises with people) |
| 3 | BME280 humidity | Seed I2C 0x76 | Breathing confirmation / zone |
| 4 | Cross-node RSSI | 2 ESP32 nodes | Rough XY position (differential triangulation) |
| 5 | Vitals stability | ESP32 CSI | HR/BR variance indicates activity level |
| 6 | Temporal CSI patterns | ESP32 CSI | Periodic=walking, stable=sitting, flat=empty |
| 7 | kNN cluster labels | Seed vector store | Natural groupings in embedding space |
| 8 | Boundary fragility | Seed Stoer-Wagner | Regime change detection (entry/exit/activity) |
| 9 | Reed switch | Seed GPIO 5 | Door open/close events |
| 10 | Vibration sensor | Seed GPIO 13 | Footstep detection |
### Camera-Free Training Phases
The pipeline extends the base 5 phases with camera-free-specific phases:
```
Phase 0: Multi-Modal Data Collection
├── UDP port 5006 → ESP32 CSI features + vitals
├── HTTPS → Seed sensor embeddings (45-dim, every 100ms)
├── HTTPS → Seed boundary/coherence (every 10s)
└── Build synchronized MultiModalFrame timeline
Phase 1: Weak Label Generation
├── Presence: PIR || CSI_presence > 0.3 || temp_rising > 0.1°C/min
├── Position: RSSI differential → 5×5 grid (25 zones)
├── Activity: CSI variance + FFT periodicity → stationary/walking/gesture/empty
├── Occupancy: max(node1_persons, node2_persons) validated by temp
├── Body region: upper/lower subcarrier groups → which body part moves
├── Entry/exit: reed_switch + PIR transition + boundary fragility spike
├── Breathing zone: humidity change rate → person location
└── Pose proxy: 5-keypoint coarse pose from RSSI + subcarrier asymmetry + vibration
Phase 2: Enhanced Contrastive Pretraining
├── Base triplets (temporal, cross-node, transition, scenario boundary)
├── Sensor-verified negatives: PIR=0 vs PIR=1 must differ
├── Activity boundary: before/after fragility spike must differ
└── Cross-modal: CSI embedding ≈ Seed embedding for same state
Phase 3: Pose Proxy Training (5-keypoint)
├── Head: RSSI centroid between 2 nodes
├── Hands: per-subcarrier variance asymmetry (left/right from 2 nodes)
├── Feet: vibration sensor + RSSI ground reflection
└── Skeleton physics constraints (anthropometric bone length limits)
Phase 4: 17-Keypoint Interpolation
├── Shoulders = 0.3 × head + 0.7 × hands
├── Elbows = midpoint(shoulder, hand)
├── Hips = midpoint(head, feet)
├── Knees = midpoint(hip, foot)
├── Face = derived from head position
└── Iterative bone length constraint projection (3 iterations)
Phase 5: Self-Refinement Loop (3 rounds)
├── Run inference on all collected data
├── Keep predictions where temporal consistency confidence > 0.8
├── Use as pseudo-labels for next training round
└── Decaying learning rate per round (diminishing returns)
```
### Seed API Endpoints Used
| Endpoint | Data | Collection Rate |
|----------|------|----------------|
| `GET /api/v1/sensor/stream` | SSE sensor readings | Continuous (100ms) |
| `GET /api/v1/sensor/embedding/latest` | 45-dim sensor embedding | Per-frame |
| `GET /api/v1/boundary` | Fragility score | Every 10s |
| `GET /api/v1/coherence/profile` | Temporal phase boundaries | Every 10s |
| `GET /api/v1/store/query` | kNN similarity search | On demand |
| `POST /api/v1/boundary/recompute` | Trigger analysis | On regime change |
### Graceful Degradation
The pipeline works with or without the Cognitum Seed:
| Mode | Signals | Pose Quality |
|------|---------|-------------|
| Full (Seed + 2 ESP32) | 10 signals | 5-keypoint trained, 17-keypoint interpolated |
| CSI-only (2 ESP32) | 3 signals (RSSI, vitals, temporal) | Coarser position/activity only |
| Single node | 2 signals (vitals, temporal) | Presence + activity only |
When the Seed API is unreachable, the pipeline automatically falls back to
CSI-only training, producing the same output format (SafeTensors, HuggingFace,
quantized) with reduced label quality.
### Output Format
Same as the base pipeline (SafeTensors + HuggingFace compatible), plus:
| File | Description |
|------|-------------|
| `pose-decoder.json` | 5-keypoint pose decoder weights |
| `model.rvf.jsonl` | Extended with `camera_free_supervision` record |
| `training-metrics.json` | Includes weak label stats and multi-modal triplet counts |
### Usage
```bash
# Full pipeline with Seed
node scripts/train-camera-free.js \
--data data/recordings/pretrain-*.csi.jsonl \
--seed-url https://169.254.42.1:8443 \
--output models/csi-camerafree-v1
# CSI-only (no Seed)
node scripts/train-camera-free.js \
--data data/recordings/pretrain-*.csi.jsonl \
--no-seed \
--output models/csi-camerafree-v1
# With benchmark

# ADR-072: WiFlow Pose Estimation Architecture
- **Status**: Proposed
- **Date**: 2026-04-02
- **Deciders**: ruv
- **Relates to**: ADR-071 (ruvllm Training Pipeline), ADR-070 (Self-Supervised Pretraining), ADR-024 (Contrastive CSI Embedding / AETHER), ADR-069 (Cognitum Seed CSI Pipeline)
## Context
The WiFi-DensePose project needs a neural architecture that can convert raw CSI amplitude
data into 17-keypoint COCO pose estimates. The existing `train-ruvllm.js` pipeline uses a
simple 2-layer FC encoder (8 -> 64 -> 128) that produces contrastive embeddings for
presence detection but cannot output spatial keypoint coordinates.
We evaluated published WiFi-based pose estimation architectures:
| Architecture | Params | Input | Key Innovation | Publication |
|-------------|--------|-------|---------------|-------------|
| **WiFlow** | 4.82M | 540x20 | TCN + AsymConv + Axial Attention | arXiv:2602.08661 |
| WiPose | 11.2M | 3x3x30x20 | 3D CNN + heatmap regression | CVPR 2021 |
| MetaFi++ | 8.6M | 114x30x20 | Transformer + meta-learning | NeurIPS 2023 |
| Person-in-WiFi 3D | 15.3M | Multi-antenna | Deformable attention + 3D | CVPR 2024 |
WiFlow is the lightest published SOTA architecture, designed specifically for commercial
WiFi hardware. Its key advantage is operating on CSI amplitude only (no phase), which
is critical for ESP32-S3 where phase calibration is unreliable.
### Why WiFlow
1. **Lightest SOTA**: 4.82M parameters at original scale; our adaptation targets ~2.5M
2. **Amplitude-only**: Discards phase, which is noisy on consumer hardware
3. **Published architecture**: Fully specified in arXiv:2602.08661, reproducible
4. **Temporal modeling**: TCN with dilated causal convolutions captures motion dynamics
5. **Efficient attention**: Axial attention reduces O(H^2W^2) to O(H^2W + HW^2)
6. **Proven on commercial WiFi**: Validated on commodity Intel 5300 and Atheros hardware
## Decision
Implement the WiFlow architecture in pure JavaScript (ruvllm native) with the following
adaptations for our ESP32 single TX/RX deployment.
### Architecture Overview
```
CSI Amplitude [128, 20]
|
Stage 1: TCN (Dilated Causal Conv)
dilation = (1, 2, 4, 8), kernel = 7
128 -> 256 -> 192 -> 128 channels
|
Stage 2: Asymmetric Conv Encoder
1xk conv (k=3), stride (1,2)
[1, 128, 20] -> [256, 8, 20]
|
Stage 3: Axial Self-Attention
Width (temporal): 8 heads
Height (feature): 8 heads
|
Decoder: Adaptive Avg Pool + Linear
[256, 8, 20] -> pool -> [2048] -> [17, 2]
|
17 COCO Keypoints [x, y] in [0, 1]
```
### Our Adaptation vs Original WiFlow
| Aspect | WiFlow Original | Our Adaptation | Reason |
|--------|----------------|----------------|--------|
| Input channels | 540 (18 links x 30 SC) | 128 (1 TX x 1 RX x 128 SC) | Single ESP32 link |
| Time steps | 20 | 20 | Same |
| TCN channels | 540 -> 256 -> 128 -> 64 | 128 -> 256 -> 192 -> 128 | Proportional reduction |
| Spatial blocks | 4 (stride 2) | 4 (stride 2) | Same |
| Attention heads | 8 | 8 | Same |
| Parameters | 4.82M | ~1.8M | Fewer input channels |
| Input type | Amplitude only | Amplitude only | Same |
| Output | 17 x 2 | 17 x 2 | Same |
### Parameter Budget Breakdown
| Stage | Parameters | % of Total |
|-------|-----------|------------|
| TCN (4 blocks, k=7, d=1,2,4,8) | ~969K | 54% |
| Asymmetric Conv (4 blocks, 1x3, stride 2) | ~174K | 10% |
| Axial Attention (width + height, 8 heads) | ~592K | 33% |
| Pose Decoder (pool + linear -> 17x2) | ~70K | 4% |
| **Total** | **~1.8M** | **100%** |
### Loss Function
```
L = L_H + 0.2 * L_B
L_H = SmoothL1(predicted, target, beta=0.1)
L_B = (1/14) * sum_b (bone_length_b - prior_b)^2
```
14 bone connections enforce anatomical constraints:
- Nose-eye (x2): 0.06
- Eye-ear (x2): 0.06
- Shoulder-elbow (x2): 0.15
- Elbow-wrist (x2): 0.13
- Shoulder-hip (x2): 0.26
- Hip-knee (x2): 0.25
- Knee-ankle (x2): 0.25
- Shoulder width: 0.20
All lengths normalized to person height.
### Training Strategy (Camera-Free Pipeline)
Since we have no ground-truth pose labels from cameras, training proceeds in three phases:
#### Phase 1: Contrastive Pretraining
- Temporal triplets: adjacent windows are positive pairs, distant windows are negative
- Cross-node triplets: same-time windows from different ESP32 nodes are positive
- Uses ruvllm `ContrastiveTrainer` with triplet + InfoNCE loss
- Learns a representation where similar CSI states cluster together
#### Phase 2: Pose Proxy Training
- Generate coarse pose proxies from vitals data:
- Person detected (presence > 0.3): place standing skeleton at center
- High motion: perturb limb positions proportional to motion energy
- Breathing: add micro-oscillation to torso keypoints
- Train with SmoothL1 + bone constraint loss
- Confidence-weighted updates (higher presence = stronger gradient)
#### Phase 3: Self-Refinement (Future)
- Multi-node consistency: same person seen from different nodes should produce
consistent pose after geometric transform
- Temporal smoothness: adjacent frames should produce similar poses
- Bone constraint tightening: gradually reduce tolerance
### Integration with Existing Pipeline
```
train-ruvllm.js (ADR-071) train-wiflow.js (ADR-072)
| |
| 8-dim features | 128-dim raw CSI amplitude
| -> 128-dim embedding | -> 17x2 keypoint coordinates
| -> presence/activity/vitals | -> bone-constrained pose
| |
+-- ContrastiveTrainer -----+------+
+-- TrainingPipeline -------+------+
+-- LoRA per-node ----------+------+
+-- TurboQuant quantize ----+------+
+-- SafeTensors export -----+------+
```
Both pipelines share the ruvllm infrastructure; WiFlow adds the deeper architecture
for direct pose regression while the simple encoder handles embedding tasks.
### Performance Targets
| Metric | Target | Notes |
|--------|--------|-------|
| PCK@20 | > 80% | On lab data with 2+ nodes |
| Forward latency | < 50ms | Pi Zero 2W at INT8 |
| Model size (INT8) | < 2 MB | TurboQuant |
| Bone violation rate | < 10% | 50% tolerance |
| Temporal jitter | < 3cm | Exponential smoothing |
### Risk Assessment
| Risk | Severity | Mitigation |
|------|----------|------------|
| Single TX/RX has less spatial info than 18 links | High | 2-node multi-static compensates; cross-node fusion from ADR-029 |
| Camera-free labels are coarse | Medium | Bone constraints enforce anatomy; contrastive pretrain provides structure |
| Pure JS too slow for real-time | Medium | INT8 quantization; axial attention is O(H^2W+HW^2) not O(H^2W^2) |
| Overfitting with ~5K frames | Medium | Temporal augmentation + noise + cross-node interpolation |
| Phase not available (amplitude-only) | Low | WiFlow was designed amplitude-only; not a limitation |
## Consequences
### Positive
- Proven SOTA architecture adapted to our hardware constraints
- Pure JavaScript implementation runs everywhere ruvllm runs (Node.js, browser WASM)
- Bone constraints enforce physically plausible outputs even with noisy inputs
- Shares training infrastructure with existing ruvllm pipeline
- Modular: each stage (TCN, AsymConv, Axial, Decoder) is independently testable
### Negative
- ~1.8M parameters is 193x larger than simple CsiEncoder (9,344 params)
- Forward pass is slower (~50ms vs <1ms for simple encoder)
- Camera-free training will produce lower accuracy than supervised WiFlow
- No ground-truth PCK evaluation possible without camera labels
- Axial attention is O(N^2) within each axis, limiting scalability
### Neutral
- FLOPs dominated by TCN (~48%) due to dilated convolutions
- INT8 quantization brings model to ~1.7MB, viable for edge deployment
- Architecture is fixed (no NAS); future work could explore lighter variants

# ADR-073: Multi-Frequency Mesh Scanning
| Field | Value |
|-------------|--------------------------------------------|
| **Status** | Proposed |
| **Date** | 2026-04-02 |
| **Authors** | ruv |
| **Depends** | ADR-018 (binary frame), ADR-029 (channel hopping), ADR-039 (edge processing), ADR-060 (channel override) |
## Context
The current WiFi-DensePose deployment uses 2 ESP32-S3 nodes operating on a single WiFi channel (channel 5, 2432 MHz). A scan of the office environment reveals 9 WiFi networks across 6 distinct channels (1, 3, 5, 6, 9, 11), each broadcasting continuously. These neighbor networks are free RF illuminators whose signals pass through the room and interact with objects, people, and walls.
**Current single-channel limitations:**
1. **19% null subcarriers** — metal objects (desk, monitor frame, filing cabinet) create frequency-selective fading that blocks specific subcarriers on channel 5. These nulls are permanent blind spots in the RF map.
2. **No frequency diversity** — objects that are transparent at 2432 MHz may be opaque at 2412 MHz or 2462 MHz, and vice versa. A metal mesh that blocks one wavelength (122.5 mm at 2432 MHz) may pass another (124.0 mm at 2412 MHz) due to the mesh aperture-to-wavelength ratio.
3. **Single-perspective CSI** — both nodes see the same 52-64 subcarriers on the same channel. The subcarrier indices map to the same frequency bins, providing no spectral diversity.
4. **Neighbor illuminator waste** — 6 other APs broadcast continuously in the room. Their signals pass through walls, furniture, and people, creating CSI-measurable reflections that we currently ignore because we only listen on channel 5.
## Decision
Implement interleaved multi-frequency channel hopping across the 2 ESP32-S3 nodes, scanning 6 WiFi channels to build a wideband RF map of the room.
### Channel Allocation Strategy
The 2.4 GHz ISM band has 3 non-overlapping 20 MHz channels (1, 6, 11) and several partially-overlapping channels between them. We allocate channels to maximize both spectral coverage and illuminator exploitation:
```
Node 1: ch 1, 6, 11 (non-overlapping, full band coverage)
Node 2: ch 3, 5, 9 (interleaved, near neighbor APs)
```
**Rationale for this split:**
| Channel | Freq (MHz) | Node | Neighbor Illuminators | Purpose |
|---------|------------|------|----------------------------------------------|-----------------------------------|
| 1 | 2412 | 1 | (none visible, but lower freq = better penetration) | Low-frequency penetration |
| 3 | 2422 | 2 | conclusion mesh (signal 44) | Exploit neighbor AP as illuminator |
| 5 | 2432 | 2 | ruv.net (100), Cohen-Guest (100), HP LaserJet (94) | Primary channel, strongest illuminators |
| 6 | 2437 | 1 | Innanen (signal 19) | Center band, non-overlapping |
| 9 | 2452 | 2 | NETGEAR72 (42), NETGEAR72-Guest (42) | Exploit dual NETGEAR illuminators |
| 11 | 2462 | 1 | COGECO-21B20 (100), COGECO-4321 (30) | High-frequency, strong illuminators |
Each node dwells on a channel for 250 ms (configurable), collects 3-4 CSI frames, then hops to the next. The 3-channel rotation completes in 750 ms, giving ~1.3 full rotations per second.
### Physics Basis
At 2.4 GHz, WiFi wavelength ranges from 122.0 mm (ch 14, 2484 MHz) to 124.0 mm (ch 1, 2412 MHz). While this is a narrow range (~2%), the effect on multipath is significant:
1. **Frequency-selective fading**: multipath reflections create constructive/destructive interference patterns that vary with frequency. A 2 cm path length difference produces a null at 2432 MHz but constructive interference at 2412 MHz.
2. **Diffraction around objects**: Huygens-Fresnel diffraction depends on wavelength. Objects smaller than ~lambda/2 (61 mm) scatter differently across the band. Common office objects (monitor bezels, chair legs, cable bundles) are in this range.
3. **Material transparency**: some materials (wire mesh, perforated metal, PCB ground planes) have frequency-dependent transmission. A monitor's EMI shielding mesh with 5 mm apertures blocks 2.4 GHz signals but the exact attenuation varies with frequency due to slot antenna effects.
4. **Subcarrier orthogonality**: OFDM subcarriers on different channels are in different frequency bins. A null on subcarrier 15 of channel 5 does not imply a null on subcarrier 15 of channel 1, because they map to different absolute frequencies.
### Null Diversity Mechanism
```
Channel 5 subcarriers: ▅▆█▇▅▃▁_▁▃▅▆█▇▅▃▁_▁▃▅▆█▇▅▃
^ null (metal desk)
Channel 1 subcarriers: ▃▅▆█▇▅▃▅▆█▇▅▃▅▆█▇▅▃▅▆█▇▅▃▅▃
^ resolved! Different freq = different null pattern
Channel 11 subcarriers: ▅▃▁_▁▃▅▆█▇▅▃▅▆▅▃▁_▁▃▅▆█▇▅▃▅
^ null here instead (shifted by frequency offset)
```
By fusing subcarrier data across channels, nulls that exist on one channel are filled by non-null data from other channels. The remaining nulls (present on ALL channels) represent truly opaque objects — large metal surfaces that block all 2.4 GHz frequencies.
### Wideband View
Single channel: ~52-64 subcarriers (20 MHz bandwidth)
Multi-channel (6 channels): ~312-384 effective subcarrier observations (120 MHz coverage)
This is not simply 6x the resolution (the subcarrier spacing within each channel is the same), but it provides:
- 6x the spectral diversity for null mitigation
- 6x the illuminator variety (different APs = different signal paths)
- Frequency-dependent scattering signatures for material classification
## Integration
### Firmware (already supported)
The channel hopping infrastructure is already implemented in the ESP32 firmware (ADR-029):
```c
// csi_collector.h — already exists
void csi_collector_set_hop_table(const uint8_t *channels, uint8_t hop_count, uint32_t dwell_ms);
void csi_collector_start_hop_timer(void);
```
The ADR-018 binary frame header already includes the channel/frequency field at bytes [8..11], so the server-side parser can distinguish frames from different channels without any firmware changes.
### Provisioning Commands
```bash
# Node 1 (COM7): non-overlapping channels 1, 6, 11
python firmware/esp32-csi-node/provision.py --port COM7 \
--ssid "ruv.net" --password "..." --target-ip 192.168.1.20 \
--hop-channels 1,6,11 --hop-dwell-ms 250
# Node 2 (COM_): interleaved channels 3, 5, 9
python firmware/esp32-csi-node/provision.py --port COM_ \
--ssid "ruv.net" --password "..." --target-ip 192.168.1.20 \
--hop-channels 3,5,9 --hop-dwell-ms 250
```
Note: `--hop-channels` and `--hop-dwell-ms` require provision.py support for writing these values to NVS. If not yet implemented, the firmware's `csi_collector_set_hop_table()` can be called directly from the main init code with compile-time constants.
### Server-Side Processing
Three new Node.js scripts consume the multi-channel CSI data:
| Script | Purpose |
|--------|---------|
| `scripts/rf-scan.js` | Single-channel live RF room scanner with ASCII spectrum |
| `scripts/rf-scan-multifreq.js` | Multi-channel scanner with null diversity analysis |
| `scripts/benchmark-rf-scan.js` | Quantitative benchmark of multi-channel performance |
All scripts parse the ADR-018 binary UDP format and use the frequency field to separate frames by channel.
### Cognitum Seed Integration
The Cognitum Seed vector store (ADR-069) currently stores 1,605 vectors from single-channel CSI. With multi-frequency scanning:
1. **Per-channel feature vectors**: store separate 8-dim feature vectors for each channel, tagged with channel number. This increases the vector count to ~9,630 (6 channels x 1,605).
2. **Wideband feature vector**: concatenate or average per-channel features into a 48-dim wideband vector for richer kNN search. Objects that are ambiguous on one channel may be clearly distinguishable in the wideband representation.
3. **Null-aware embeddings**: encode null subcarrier patterns as part of the feature vector. The null pattern itself is informative — a consistent null at subcarrier 15 across all channels indicates a large metal object, while a null only on channel 5 indicates a frequency-dependent scatterer.
## Performance Targets
| Metric | Single-Channel Baseline | Multi-Channel Target | Method |
|--------|------------------------|---------------------|--------|
| Subcarrier count | ~52-64 | ~312-384 (6x) | 6 channels x 52-64 subcarriers |
| Null gap | 19% | <5% | Null diversity across channels |
| Position resolution | ~30 cm | ~15 cm | sqrt(6) improvement from independent observations |
| Per-channel FPS | 12 fps | ~4 fps | 250 ms dwell x 3 channels = 750 ms rotation |
| Total FPS (all channels) | 12 fps | ~12 fps per node (4 fps x 3 channels) |
| Wideband rotation | N/A | ~1.3 Hz | Full 3-channel rotation in 750 ms |
## Risks
### Per-Channel Sample Rate Reduction
Channel hopping reduces the per-channel sample rate from 12 fps (single channel) to approximately 4 fps per channel (250 ms dwell, 3 channels). This affects:
- **Vitals extraction**: breathing rate (0.1-0.5 Hz) requires at least 2 fps (Nyquist). At 4 fps per channel, this is met. Heart rate (0.8-2.0 Hz) requires at least 4 fps, which is marginal. Mitigation: keep one channel as "primary" with longer dwell for vitals, or fuse phase data across channels.
- **Motion tracking**: 4 fps is sufficient for walking speed (<2 m/s) but insufficient for fast gestures. If gesture recognition is needed, reduce to 2-channel hopping or increase dwell rate.
### Channel Hopping Latency
`esp_wifi_set_channel()` takes ~1-5 ms on ESP32-S3. During the transition, no CSI frames are captured. At 250 ms dwell, this is <2% overhead.
### AP Disconnection
Channel hopping may cause the ESP32 to lose connection to the home AP (ruv.net on channel 5) when dwelling on other channels. The STA reconnects automatically, but there may be brief UDP packet loss. Mitigation: the firmware already handles this gracefully — CSI collection works in promiscuous mode regardless of STA connection state.
### Increased Server Load
2 nodes x 3 channels x 4 fps = 24 frames/second total UDP traffic. Each frame is ~150-200 bytes (20-byte header + 64 subcarriers x 2 bytes I/Q). Total: ~4.8 KB/s — negligible.
## Alternatives Considered
1. **5 GHz channels**: ESP32-S3 supports 5 GHz CSI, and the shorter wavelength (60 mm) provides better spatial resolution. Rejected because: (a) no 5 GHz APs visible in the current environment, so no free illuminators; (b) 5 GHz has worse wall penetration, reducing the effective sensing volume.
2. **More nodes**: adding a 3rd or 4th ESP32 node would increase spatial diversity without channel hopping. Rejected for now due to cost, but this is complementary — more nodes + channel hopping would give both spatial and spectral diversity.
3. **Wider bandwidth (HT40)**: using 40 MHz channels doubles subcarrier count per channel. Rejected because: (a) HT40 requires a secondary channel, reducing available channels for hopping; (b) many neighbor APs use HT20, so their illumination only covers 20 MHz.
## SNN Integration (ADR-074)
Multi-frequency scanning produces subcarrier data across 6 channels, creating temporal patterns that are well-suited for spiking neural network processing. ADR-074 introduces an SNN with STDP learning that consumes the multi-channel CSI stream.
**Key interactions with multi-frequency data:**
1. **Null diversity as SNN input**: subcarriers that are null on one channel but active on another produce a distinctive spike pattern (spikes only during certain channel dwells). STDP learns to associate these cross-channel patterns with specific objects or zones — something a single-channel SNN cannot do.
2. **Channel-interleaved temporal coding**: because each node dwells on 3 channels in a 750ms rotation, the SNN receives subcarrier data in a repeating temporal pattern (ch1 → ch2 → ch3 → ch1 ...). The SNN's LIF membrane dynamics integrate spikes across the rotation, naturally performing cross-channel fusion through temporal summation. A hidden neuron that receives spikes from subcarrier 15 on channel 1 AND subcarrier 15 on channel 6 will fire more strongly than one receiving either alone.
3. **Expanded input mode**: on the server (not constrained by ESP32 memory), the SNN can use 384 input neurons (6 channels x 64 subcarriers) instead of 128. This provides maximum spectral diversity per frame but requires ~150 KB of weight storage. The `snn-csi-processor.js` script supports this via the `--hidden` flag to scale the network.
4. **Illuminator fingerprinting**: different neighbor APs have different beamforming patterns and power levels. The SNN learns which subcarrier patterns belong to which illuminator, enabling it to distinguish AP-specific signatures from human-caused perturbations. This is especially useful for the NETGEAR dual-AP setup on channel 9, where two illuminators from different positions create stereo-like RF coverage.

# ADR-074: Spiking Neural Network for CSI Sensing
| Field | Value |
|-------------|--------------------------------------------|
| **Status** | Proposed |
| **Date** | 2026-04-02 |

## Context
The current WiFi-DensePose CSI sensing pipeline uses two approaches for interpreting subcarrier data:
1. **Static thresholds** — presence detection fires when subcarrier variance exceeds a fixed value. This works in calibrated environments but fails when the RF landscape changes (furniture moved, new objects, temperature drift). Recalibration requires manual intervention or batch retraining.
2. **Batch-trained FC encoder** — the neural network in `wifi-densepose-nn` maps CSI frames to 8-dimensional feature vectors. It requires labeled training data, offline training epochs, and model deployment. The encoder cannot adapt to a new environment without collecting new data and retraining.
Neither approach handles online adaptation. When an ESP32 node is deployed in a new room, the first hours produce noisy, unreliable output until the thresholds are tuned or a model is trained. In disaster scenarios (ADR MAT), there is no time for calibration.
**Spiking Neural Networks (SNNs)** offer an alternative. Unlike traditional ANNs that process continuous values in batch mode, SNNs communicate through discrete spike events and learn online via Spike-Timing-Dependent Plasticity (STDP). This is a natural fit for CSI data:
- CSI subcarrier amplitudes are temporal signals sampled at 12-22 fps
- Amplitude changes (not absolute values) carry the information about motion, breathing, and presence
- STDP learns temporal correlations between subcarriers without labels
- Event-driven processing means idle rooms (no motion) consume near-zero compute
The `@ruvector/spiking-neural` package (vendored at `vendor/ruvector/npm/packages/spiking-neural/`) provides production-ready LIF neurons, STDP learning, lateral inhibition, and SIMD-optimized vector math in pure JavaScript with zero dependencies.
## Decision
Integrate `@ruvector/spiking-neural` into the CSI sensing pipeline as an online unsupervised pattern learner that runs alongside the existing FC encoder. The SNN provides real-time adaptation while the FC encoder provides stable baseline predictions.
### Network Architecture
```
CSI Frame (128 subcarriers)
|
v
[ Rate Encoding ] -----> 128 input neurons (one per subcarrier)
| amplitude delta -> spike rate
v
[ LIF Hidden Layer ] ---> 64 hidden neurons (tau=20ms)
| STDP learns subcarrier correlations
| lateral inhibition -> sparse codes
v
[ LIF Output Layer ] ---> 8 output neurons
|
v
presence | motion | breathing | heart_rate | phase_var | persons | fall | rssi
```
**Layer parameters:**
| Layer | Neurons | tau (ms) | v_thresh (mV) | Function |
|-------|---------|----------|---------------|----------|
| Input | 128 | N/A | N/A | Rate-coded spike generation from subcarrier deltas |
| Hidden | 64 | 20.0 | -50.0 | STDP learns correlated subcarrier groups |
| Output | 8 | 25.0 | -50.0 | Each neuron specializes in one sensing modality |
**Synapse parameters:**
| Connection | Count | a_plus | a_minus | w_init | Lateral Inhibition |
|------------|-------|--------|---------|--------|-------------------|
| Input -> Hidden | 8,192 | 0.005 | 0.005 | 0.3 | No |
| Hidden -> Output | 512 | 0.003 | 0.003 | 0.2 | Yes (strength=15.0) |
Total synapses: 8,704. At 4 bytes per weight, this is 34 KB — fits in ESP32 SRAM.
### Input Encoding
CSI amplitudes are converted to spike rates using rate coding:
1. Compute per-subcarrier amplitude: `amp[i] = sqrt(I[i]^2 + Q[i]^2)` from the ADR-018 binary frame
2. Compute amplitude delta from previous frame: `delta[i] = |amp[i] - prev_amp[i]|`
3. Normalize deltas to [0, 1] range: `norm[i] = min(delta[i] / max_delta, 1.0)`
4. Feed `norm` to `rateEncoding(norm, dt, max_rate)` which produces Poisson spikes
Higher amplitude changes produce more spikes. Static subcarriers (no motion) produce few or no spikes. This is the key energy advantage: an empty room generates almost no spikes, so the SNN does almost no work.
### STDP Learning Rule
STDP strengthens connections between neurons that fire together (within a time window) and weakens connections between neurons that fire out of sync:
- **LTP (Long-Term Potentiation)**: if a presynaptic neuron fires before a postsynaptic neuron within 20ms, the weight increases by `a_plus * exp(-dt/tau_stdp)`
- **LTD (Long-Term Depression)**: if a postsynaptic neuron fires before a presynaptic neuron, the weight decreases by `a_minus * exp(-dt/tau_stdp)`
Over time, this causes the hidden layer neurons to specialize. Subcarriers that consistently change together (e.g., subcarriers 10-20 affected by a person walking through zone A) become strongly connected to the same hidden neuron. Different motion patterns activate different hidden neuron clusters.
### Lateral Inhibition (Winner-Take-All)
The output layer uses lateral inhibition with strength 15.0. When one output neuron fires, it suppresses all others. This forces each output neuron to specialize in a distinct pattern:
- Output 0: presence (any subcarrier activity above baseline)
- Output 1: motion (widespread subcarrier changes, high spike rate)
- Output 2: breathing (periodic 0.1-0.5 Hz modulation on chest-area subcarriers)
- Output 3: heart rate (periodic 0.8-2.0 Hz modulation, lower amplitude than breathing)
- Output 4: phase variance (phase instability across subcarriers)
- Output 5: person count (number of distinct active subcarrier clusters)
- Output 6: fall (sudden high-amplitude burst followed by silence)
- Output 7: RSSI trend (overall signal strength change)
The neuron-to-label mapping is not fixed by training. Instead, the mapping is discovered by observing which output neuron fires most for each known condition during an optional calibration phase. If no calibration is available, the output is reported as raw spike counts per output neuron, and downstream consumers (Cognitum Seed, SONA) interpret the patterns.
### Integration with Existing Pipeline
The SNN does not replace the FC encoder. It runs in parallel:
```
CSI Frame ----+----> FC Encoder --------> 8-dim feature vector (stable, trained)
|
+----> SNN (STDP) --------> 8-dim spike rate vector (adaptive, online)
|
+----> SONA Adapter -------> Weighted fusion of both signals
```
SONA (Self-Optimizing Neural Architecture) receives both signals and learns which source is more reliable for each output dimension. In a new environment where the FC encoder has not been retrained, SONA automatically weights the SNN output higher because it adapts faster. As the FC encoder is retrained on local data, SONA shifts weight back toward it.
### Energy and Compute Budget
| Metric | FC Encoder | SNN (STDP) | Ratio |
|--------|-----------|------------|-------|
| Compute per frame (idle room) | 8,192 MACs | ~50 spike events | ~160x less |
| Compute per frame (active room) | 8,192 MACs | ~500 spike events | ~16x less |
| Memory | 34 KB weights | 34 KB weights | Equal |
| Adaptation | Offline retraining | Online, continuous | SNN wins |
| Stability | High (frozen weights) | Lower (weights drift) | FC wins |
| Latency to first useful output | Hours (needs training data) | ~30 seconds | SNN wins |
The SNN's event-driven nature means it processes only spikes, not every subcarrier on every frame. In an idle room with no motion, subcarrier deltas are near zero, spike rates drop to near zero, and the SNN consumes negligible compute. This is ideal for battery-powered or thermally constrained deployments (ESP32, Cognitum Seed Pi Zero).
### Deployment Targets
| Platform | Runtime | Notes |
|----------|---------|-------|
| Node.js server | `require('@ruvector/spiking-neural')` | Primary. Receives UDP frames, runs SNN. |
| Cognitum Seed (Pi Zero) | Node.js ARM | 34 KB model fits. ~0.06ms per step at 100 neurons. |
| ESP32-S3 (WASM) | wasm3 interpreter | Optional. SNN weights exported as flat Float32Array. |
| Browser | WebAssembly or JS | Via `wifi-densepose-wasm` crate's JS bindings. |
### Multi-Channel SNN (ADR-073 Integration)
With multi-frequency mesh scanning (ADR-073), the SNN input expands:
- **Single-channel mode**: 128 input neurons (64 subcarriers x 2 for I/Q or amplitude/phase)
- **Multi-channel mode**: 128 input neurons, but the subcarrier index rotates across channels. Each channel's subcarriers map to the same neuron indices, but at different time slots. The SNN's temporal dynamics naturally integrate cross-channel information because STDP operates across time.
Alternatively, for maximum spectral diversity, a wider SNN (384 input neurons for 6 channels x 64 subcarriers) can be used on the server where memory is not constrained.
## Performance Targets
| Metric | Target | Method |
|--------|--------|--------|
| SNN step latency | <0.1ms | 128-64-8 network, ~8,700 synapses |
| STDP convergence | <30 seconds | ~360 frames at 12 fps, patterns stabilize |
| Output accuracy (after adaptation) | >80% | Compared to manually labeled ground truth |
| Memory footprint | <50 KB | Weights + neuron state |
| Idle room spike rate | <10 spikes/frame | Event-driven: near-zero compute when nothing moves |
| Adaptation to new environment | <2 minutes | STDP relearns subcarrier correlations |
## Risks
### Weight Drift
STDP learning never stops. In a stable environment, weights can slowly drift as the network over-fits to the current RF landscape. Mitigation: implement weight decay (multiply all weights by 0.999 per second) and clamp weights to [w_min, w_max].
### Output Neuron Reassignment
If the RF environment changes significantly (new furniture, different room), output neurons may reassign their specialization. The mapping from output neuron index to label (presence, motion, etc.) may change. Mitigation: periodically log the output neuron activity and detect reassignment events. Downstream consumers should use the spike pattern, not the neuron index, for classification.
### Interference with FC Encoder
If SONA naively averages the SNN and FC encoder outputs, a poorly adapted SNN could degrade overall accuracy. Mitigation: SONA uses confidence-weighted fusion. The SNN output includes a confidence signal (total spike count / expected spike count). Low confidence = low weight.
### STDP Learning Rate Sensitivity
If `a_plus` and `a_minus` are too high, the SNN oscillates and never converges. If too low, adaptation takes too long. The default values (0.005 and 0.003) are conservative. The script includes a `--learning-rate` flag for tuning.
## Alternatives Considered
1. **Online gradient descent on FC encoder** — backprop through the FC network with each new frame. Rejected because: (a) requires a loss function, which requires labels; (b) continuous gradient updates on a small model lead to catastrophic forgetting of the pretrained representations.
2. **Adaptive thresholds only** — replace fixed thresholds with exponentially-weighted moving averages. Rejected because: (a) single-variable thresholds cannot capture multi-subcarrier correlations; (b) no representation learning — each subcarrier is still processed independently.
3. **Reservoir computing (Echo State Network)** — use a fixed random recurrent network as a temporal feature extractor. Partially viable, but: (a) requires a linear readout layer trained with labels; (b) the random reservoir does not adapt to the specific RF environment.
4. **Train SNN with supervision** — use surrogate gradient methods to train the SNN on labeled data. Rejected because: (a) defeats the purpose of online unsupervised learning; (b) the `@ruvector/spiking-neural` package does not implement surrogate gradients.
## Implementation
The integration is implemented in `scripts/snn-csi-processor.js`, a standalone Node.js script that:
1. Receives live CSI frames via UDP (port 5006, ADR-018 binary format)
2. Decodes subcarrier I/Q data and computes amplitude deltas
3. Feeds deltas through rate encoding into the SNN
4. Applies STDP learning on every frame (online, unsupervised)
5. Maps output neuron spike counts to sensing labels
6. Prints real-time ASCII visualization of SNN activity
7. Optionally forwards learned patterns to Cognitum Seed

# ADR-075: Min-Cut Based Person Separation from Subcarrier Correlation
- **Status:** Proposed
- **Date:** 2026-04-02
- **Issue:** #348`n_persons` always reports 4 regardless of actual occupancy
- **Depends on:** ADR-016 (RuVector integration), ADR-041 (person tracking), ADR-073 (multifrequency mesh scan)
## Context
### The Bug
Issue #348 reports that the ESP32 firmware's multi-person counting always reports
`n_persons = 4`. The root cause is in the WASM edge module
`sig_mincut_person_match.rs`, which uses a fixed `MAX_PERSONS = 4` constant and a
threshold-based variance classifier to populate person slots. The classifier bins
subcarriers into "dynamic" vs "static" using a single fixed variance threshold
(`DYNAMIC_VAR_THRESH = 0.15`). In practice:
1. The threshold is miscalibrated for real-world CSI data — almost any room with
multipath reflections pushes a majority of subcarriers above 0.15 variance.
2. The subcarrier-to-person assignment uses a greedy Hungarian-lite matcher that
fills all 4 slots once there are >= 4 dynamic subcarriers (which is nearly
always the case).
3. There is no mechanism to determine how many independent movers exist — the
algorithm assumes all 4 slots should be filled.
### Prior Art
The Rust crate `ruvector-mincut` (vendored at `vendor/ruvector/crates/ruvector-mincut/`)
implements a full dynamic min-cut algorithm with O(n^{o(1)}) amortized update time,
Stoer-Wagner exact min-cut, and online edge insert/delete. It is already integrated
in the training pipeline (`wifi-densepose-train/src/metrics.rs`) via
`DynamicPersonMatcher`.
### WiFi Sensing Insight
When a person moves through a room, they perturb the Fresnel zones of specific
subcarrier frequencies. Subcarriers whose Fresnel zones overlap the person's body
change **together** — their amplitudes are temporally correlated. When two people
move independently, they create two **separate** groups of correlated subcarriers.
This correlation structure forms a natural graph partitioning problem.
## Decision
Replace the fixed-threshold person counter with a spectral min-cut algorithm
operating on the subcarrier temporal correlation graph. This runs in the bridge
script (`scripts/mincut-person-counter.js`) or on Cognitum Seed, and feeds the
corrected person count back to the feature vector before ingest.
### Algorithm
1. **Sliding window accumulation**: Maintain the last 2 seconds of subcarrier
amplitude data (~40 frames at 20 fps). Each frame provides a 64-element
amplitude vector (one per subcarrier).
2. **Pairwise Pearson correlation**: For all subcarrier pairs (i, j), compute
the Pearson correlation coefficient over the sliding window:
```
r(i,j) = cov(amp_i, amp_j) / (std(amp_i) * std(amp_j))
```
This produces a 64x64 correlation matrix.
3. **Graph construction**: Build a weighted undirected graph:
- **Nodes** = subcarriers (64 for single-antenna ESP32-S3, up to 128 for dual)
- **Edges** = pairs with |r(i,j)| > 0.3 (correlation threshold)
- **Weight** = |r(i,j)| (correlation strength)
- Discard null subcarriers (amplitude consistently near zero)
- Expected: ~1500-2500 edges for 64 active subcarriers
4. **Iterative Stoer-Wagner min-cut**: Apply the Stoer-Wagner algorithm to find
the global minimum cut. If the min-cut weight is below a separation threshold
(empirically 2.0), the cut represents a real boundary between independent
movers. Split the graph at the cut and recurse on each partition.
5. **Person count**: The number of partitions after all valid cuts = number of
independent movers = person count. A single connected component with high
internal correlation and no low-weight cut = 1 person (or 0 if variance is
also low).
6. **Empty room detection**: If the total variance across all subcarriers is
below a noise floor threshold, report 0 persons regardless of graph structure.
### Stoer-Wagner Algorithm
Stoer-Wagner finds the exact global minimum cut of an undirected weighted graph
in O(V * E) time using a sequence of "minimum cut phases":
```
function stoerWagner(G):
best_cut = infinity
while |V(G)| > 1:
(s, t, cut_of_phase) = minimumCutPhase(G)
if cut_of_phase < best_cut:
best_cut = cut_of_phase
best_partition = partition induced by t
merge(s, t) // contract vertices s and t
return best_cut, best_partition
function minimumCutPhase(G):
A = {arbitrary start vertex}
while A != V(G):
z = vertex most tightly connected to A
// "most tightly connected" = max sum of edge weights to A
add z to A
s = second-to-last vertex added
t = last vertex added (most tightly connected)
cut_of_phase = sum of weights of edges incident to t
return (s, t, cut_of_phase)
```
For V=64 subcarriers and E~2000 edges, this runs in ~8 million operations,
well under 1ms on modern hardware and under 10ms even on ESP32-S3.
### Integration Points
```
ESP32 Node 1 ──UDP 5006──┐
├──> mincut-person-counter.js ──> corrected n_persons
ESP32 Node 2 ──UDP 5006──┘ │
├──> seed_csi_bridge.py (feature dim 5 override)
└──> csi-graph-visualizer.js (debug view)
```
The person counter runs as a standalone Node.js process alongside the existing
`rf-scan.js` and `seed_csi_bridge.py` bridge scripts. It can also replay
recorded `.csi.jsonl` files for offline analysis.
## Alternatives Considered
### 1. Threshold-based peak counting (current, broken)
Count subcarriers with variance above a threshold, then cluster by proximity.
**Problem:** threshold is environment-dependent, miscalibrates easily, and
cannot distinguish correlated from independent motion.
### 2. PCA / spectral clustering on correlation matrix
Compute eigenvectors of the correlation matrix; the number of large eigenvalues
indicates the number of independent sources. **Problem:** requires choosing an
eigenvalue gap threshold, which is as fragile as the current variance threshold.
Also does not give per-person subcarrier assignments.
### 3. Min-cut on correlation graph (this ADR)
**Advantages:**
- Directly models the physical structure (Fresnel zone groupings)
- Threshold-free person counting (cut weight is a natural separation metric)
- Produces per-person subcarrier groups as a side effect
- Stoer-Wagner is simple to implement (~100 lines) and runs in polynomial time
- Already validated in Rust via `ruvector-mincut` integration
## Performance
| Metric | Value |
|--------|-------|
| Graph size | V=64, E~2000 |
| Stoer-Wagner complexity | O(V * E) = O(128,000) per cut |
| Iterative cuts (max 4) | O(512,000) total |
| Wall time (Node.js) | < 5 ms per 2-second window |
| Wall time (Rust/WASM) | < 0.5 ms |
| Memory | ~32 KB for correlation matrix + graph |
| Sliding window | 2 seconds = ~40 frames * 64 subcarriers * 8 bytes = 20 KB |
## Consequences
### Positive
- Fixes #348: person count now reflects actual independent movers
- Robust across environments (no per-room threshold calibration)
- Per-person subcarrier groups enable per-person feature extraction
- Graph visualization aids debugging and room mapping
- Algorithm is well-understood (Stoer-Wagner, 1997)
### Negative
- Adds a new process to the sensing pipeline
- 2-second latency for person count changes (sliding window)
- Correlation-based: cannot detect stationary persons (no motion = no signal)
- Assumes independent motion — two people walking in sync may be counted as one
### Migration
1. Deploy `scripts/mincut-person-counter.js` alongside existing bridge
2. Override feature vector dimension 5 (`n_persons`) with corrected count
3. Once validated, port Stoer-Wagner to C for direct ESP32-S3 firmware integration
4. Deprecate the fixed-threshold `PersonMatcher` in `sig_mincut_person_match.rs`

# ADR-076: CSI Spectrogram Embeddings via CNN + Graph Transformer
| Field | Value |
|-------------|--------------------------------------------|
| **Status** | Proposed |
| **Date** | 2026-04-02 |
| **Authors** | ruv |
| **Depends** | ADR-018 (binary frame), ADR-024 (AETHER contrastive embeddings), ADR-029 (RuvSense), ADR-069 (Cognitum Seed bridge), ADR-073 (multi-frequency mesh scan) |
## Context
The current CSI processing pipeline extracts an 8-dimensional hand-crafted feature vector per frame: mean amplitude, amplitude variance, max amplitude, mean phase, phase variance, bandwidth, spectral centroid, and RSSI. These features are effective for basic presence detection and room fingerprinting but discard the rich spatial-frequency structure present in the raw subcarrier data.
A single CSI frame from an ESP32-S3 contains 64 subcarriers (or 128 in HT40 mode), each with I/Q components. When stacked over time, 20 consecutive frames form a **64x20 subcarrier-by-time matrix** — effectively a grayscale spectrogram image. This matrix encodes:
1. **Frequency-selective fading** — metal objects create persistent null zones at specific subcarrier indices (visible as dark vertical stripes)
2. **Doppler signatures** — human motion produces time-varying amplitude patterns across subcarriers (visible as horizontal wave patterns)
3. **Multipath structure** — room geometry creates characteristic interference patterns unique to each environment
4. **Activity fingerprints** — walking, sitting, breathing, and falling produce distinct 2D texture patterns in the subcarrier-time matrix
These 2D structural patterns are invisible to the 8-dim feature vector, which collapses all subcarrier information into scalar statistics. A CNN embedding can preserve this spatial structure.
### Existing Vendor Libraries
**@ruvector/cnn** (v0.1.0) provides:
- WASM-based CNN feature extraction (~5ms per 224x224 image, ~900KB model)
- Configurable embedding dimension (default 512, we use 128 for compact storage)
- L2-normalized embeddings with cosine similarity search
- Contrastive training via InfoNCE and triplet loss
- SIMD-optimized layer operations (batch norm, global average pooling, ReLU)
- Works in both Node.js and browser environments
**ruvector-graph-transformer** provides:
- Sublinear O(n log n) graph attention via LSH bucketing and PPR sampling
- Proof-gated mutation substrate for verified computations
- Temporal causal attention with Granger causality (relevant for CSI time series)
- Manifold attention on product spaces S^n x H^m x R^k
**@ruvector/graph-wasm** (v2.0.2) provides:
- Neo4j-compatible property graph database in WASM
- Node/edge creation with arbitrary properties and embeddings
- Hyperedge support for multi-node relationships
- Cypher query language
### Current Limitations of 8-dim Features
| Limitation | Impact |
|------------|--------|
| No subcarrier-level information | Cannot distinguish frequency-selective vs broadband fading |
| No temporal pattern encoding | Walking gait (periodic) looks identical to random motion (aperiodic) |
| No 2D structure | Room fingerprint reduced to 8 numbers; two rooms with similar statistics are indistinguishable |
| No cross-subcarrier correlation | Cannot detect standing waves, node patterns, or multipath clusters |
| Poor kNN discrimination | 8 dimensions provides limited hypersphere surface area for separating environments |
## Decision
Treat the CSI subcarrier-by-time matrix as a grayscale spectrogram image and apply CNN embedding to produce a 128-dimensional representation that preserves 2D spatial-frequency structure. Use a graph transformer to fuse embeddings across multiple ESP32 nodes.

```
### Step 1: CSI-to-Spectrogram Conversion
Each ESP32 transmits CSI frames via UDP in ADR-018 binary format. The `iq_hex` field contains I/Q pairs for each subcarrier (2 bytes per subcarrier: I + Q as unsigned 8-bit values).
```
Amplitude[sc] = sqrt(I[sc]^2 + Q[sc]^2)
```
A sliding window of 20 frames produces a 64x20 matrix. Normalization to 0-255 grayscale:
```
pixel[sc][t] = clamp(255 * (amplitude[sc][t] - min) / (max - min), 0, 255)
```
Where `min` and `max` are computed over the entire 64x20 window for per-window contrast normalization. This ensures the CNN sees the relative structure regardless of absolute signal strength (which varies with distance, TX power, and environmental absorption).
### Step 2: CNN Embedding
The 64x20 grayscale matrix is resized to the CNN's expected input size (224x224 via nearest-neighbor upsampling, since we want to preserve the discrete subcarrier structure rather than blur it with bilinear interpolation). The input is replicated across 3 channels (RGB) since @ruvector/cnn expects RGB input.
Configuration:
- **Input**: 224x224x3 (upsampled from 64x20, grayscale replicated to RGB)
- **Embedding dimension**: 128 (reduced from default 512 for compact storage and faster kNN)
- **Normalization**: L2-enabled (cosine similarity = dot product on unit sphere)
- **Latency**: ~5ms per window on modern hardware
The 128-dim embedding encodes the 2D structure of the spectrogram: null zones, Doppler patterns, multipath signatures, and activity textures.
### Step 3: Graph Transformer for Multi-Node Fusion
With 2 ESP32 nodes (generalizable to N), we construct a graph:
```
Nodes: {Node_1, Node_2}
Edges: {(Node_1, Node_2, weight=cross_correlation)}
Node features: 128-dim CNN embedding per node
```
The graph attention mechanism learns which node is more informative for each prediction:
1. **Query/Key/Value** from each node's 128-dim embedding
2. **Edge weight** = Pearson cross-correlation between the two nodes' raw amplitude vectors (captures how much their CSI observations agree)
3. **Attention score** = softmax(Q_i * K_j / sqrt(d) + edge_weight_bias)
4. **Output** = weighted sum of value vectors
This produces a fused 128-dim vector that combines both nodes' perspectives, automatically weighting the node with cleaner signal (higher SNR, less fading) more heavily.
**Generalization to 3+ nodes**: Adding a third ESP32 adds one node and 2 edges to the graph. The attention mechanism handles variable-size graphs without architecture changes.
### Step 4: Storage and Search
The fused 128-dim embedding is stored in Cognitum Seed (ADR-069) alongside the existing 8-dim features:
| Store | Dimension | Content | Use Case |
|-------|-----------|---------|----------|
| `csi-features` | 8-dim | Hand-crafted statistics | Fast presence detection |
| `csi-spectrograms` | 128-dim | CNN spectrogram embedding | Environment fingerprinting, anomaly detection |
| `csi-spectrograms-fused` | 128-dim | Graph-fused multi-node embedding | Cross-viewpoint room signature |
kNN search on the 128-dim store finds past spectrograms that "look like" the current one:
- **Environment fingerprinting**: "What room does this RF pattern match?"
- **Cross-room transfer**: "Which training room is most similar to this deployment room?"
- **Anomaly detection**: Low similarity to all known patterns = unknown environment or novel activity
- **Temporal segmentation**: Similarity drops = activity transition boundaries
### Comparison: 8-dim vs 128-dim vs Combined
| Property | 8-dim hand-crafted | 128-dim CNN | Combined |
|----------|-------------------|-------------|----------|
| Subcarrier structure | Lost | Preserved | Both available |
| Temporal patterns | Lost | Preserved (20-frame window) | Both |
| Computation | ~0.1ms | ~5ms | ~5ms |
| Storage per vector | 32 bytes | 512 bytes | 544 bytes |
| kNN discrimination | Low (8-dim curse) | High (128-dim surface) | Highest |
| Interpretability | High (named features) | Low (learned) | Mixed |
| Training required | No | Optional (pre-trained works) | Optional |
| Multi-node fusion | Average/max | Graph attention | Graph attention |
### Contrastive Training (Optional Enhancement)
The CNN embedding works out-of-the-box with the pre-trained weights. For domain-specific improvements, contrastive training with CSI data:
1. **Positive pairs**: Same room, different time windows (should embed similarly)
2. **Negative pairs**: Different rooms or different activities (should embed differently)
3. **Loss**: InfoNCE with temperature 0.07 (standard SimCLR)
4. **Augmentation**: Time-shift (slide window by 1-5 frames), subcarrier dropout (zero 10% of rows), amplitude jitter (multiply by uniform [0.8, 1.2])
This teaches the CNN that "same room at different times" should produce similar embeddings, while "different rooms" should produce different embeddings.
## Consequences
### Positive
1. **Richer representation**: 128 dimensions capture 2D structure that 8 dimensions cannot
2. **Environment fingerprinting**: kNN on spectrograms can distinguish rooms that look identical in 8-dim feature space
3. **Activity detection**: Temporal patterns (gait periodicity, breathing frequency) are encoded in the spectrogram texture
4. **Multi-node fusion**: Graph attention automatically weights the most informative node, improving robustness to single-node occlusion or interference
5. **Incremental adoption**: 128-dim store operates alongside 8-dim store; no migration needed
6. **Browser-compatible**: WASM-based CNN runs in the sensing-server UI for live visualization
### Negative
1. **5ms latency per window**: Acceptable for 1.3 Hz update rate (750ms rotation from ADR-073), but constrains real-time applications
2. **900KB model download**: One-time cost, cached after first load
3. **128-dim storage**: 16x more bytes per vector than 8-dim; mitigated by the fact that we store one embedding per 20-frame window (not per frame)
4. **Opaque embeddings**: Unlike named 8-dim features, CNN embeddings are not human-interpretable
5. **Input size mismatch**: 64x20 matrix must be upsampled to 224x224; nearest-neighbor preserves structure but wastes computation on padded regions
### Risks and Mitigations
| Risk | Mitigation |
|------|------------|
| CNN embeddings not discriminative enough for CSI | Contrastive fine-tuning on CSI spectrograms; fall back to 8-dim if 128-dim kNN recall is worse |
| Graph transformer overhead for 2-node graph | Lightweight attention (single head, no MLP); O(1) for 2 nodes |
| Upsampling artifacts from 64x20 to 224x224 | Nearest-neighbor preserves discrete structure; consider training a smaller CNN on native 64x20 input |
| WASM initialization delay | Call `init()` at server startup, not per-request |

# ADR-077: Novel RF Sensing Applications
**Status:** Accepted
**Date:** 2026-04-02
**Authors:** ruv
**Depends on:** ADR-018 (CSI binary protocol), ADR-073 (multifrequency mesh scan), ADR-075 (MinCut person separation), ADR-076 (CSI spectrogram embeddings)
## Context
The existing ESP32 CSI + Cognitum Seed infrastructure collects rich multi-modal data:
- 2 ESP32-S3 nodes streaming CSI at ~22 fps each (64-128 subcarriers, channel hopping ch 1/3/5/6/9/11)
- Vitals extraction: breathing rate, heart rate, motion energy, presence score (1 Hz per node)
- 8-dimensional feature vectors per frame
- Cognitum Seed with BME280 (temp/humidity/pressure), PIR, reed switch, vibration sensor
No new hardware is required. All 6 applications below derive novel insights from data already being collected via the ADR-018 binary protocol over UDP port 5006.
## Decision
Implement 6 novel RF sensing applications as standalone Node.js scripts that process live UDP or replayed `.csi.jsonl` recordings.
---
## Application 1: Sleep Quality Monitoring
### Input
Breathing rate (BR) and heart rate (HR) time series from vitals packets (0xC5110002), sampled at ~1 Hz per node over 6-8 hours.
### Algorithm
Sliding window analysis (5-minute windows, 1-minute stride) classifying sleep stages:
| Stage | BR (BPM) | BR Variance | HR Pattern | Motion |
|-------|----------|-------------|------------|--------|
| **Deep (N3)** | 6-12 | Very low (<2.0) | Slow, regular | None |
| **Light (N1/N2)** | 12-18 | Moderate (2.0-8.0) | Normal | Minimal |
| **REM** | 15-25 | High (>8.0), irregular | Elevated | Eyes only (low CSI motion) |
| **Awake** | >18 or <6 | Any | Variable | Moderate-high |
Each 5-minute window is scored by:
1. Compute BR mean and variance within the window
2. Compute HR mean and coefficient of variation (CV)
3. Compute motion energy mean (from vitals `motion_energy` field)
4. Classify stage using threshold hierarchy: Awake > REM > Light > Deep
### Output
- Real-time sleep stage classification
- ASCII hypnogram (time vs. stage)
- Summary: total sleep time, sleep efficiency (TST / time in bed), time per stage
- Optional JSON for health app integration
### Validation
Overnight recording (`overnight-1775217646.csi.jsonl`, 113k frames, ~40 min) should show:
- Transition from active (awake) to resting states
- Decreased motion energy over time
- BR stabilization in sleeping segments
### Clinical Relevance
Consumer-grade sleep tracking without wearables. RF-based sensing avoids compliance issues (forgotten wristbands, dead batteries). Not diagnostic; informational only.
---
## Application 2: Breathing Disorder Screening (Apnea Detection)
### Input
Breathing rate time series from vitals packets at ~1 Hz.
### Algorithm
Detect respiratory events in the BR time series:
| Event | Definition | Duration |
|-------|-----------|----------|
| **Apnea** | BR drops below 3 BPM (effective cessation) | >= 10 seconds |
| **Hypopnea** | BR drops > 50% from 5-min rolling baseline | >= 10 seconds |
Scoring:
1. Maintain 5-minute rolling baseline BR (exponential moving average)
2. Flag apnea when BR < 3 BPM for >= 10 consecutive seconds
3. Flag hypopnea when BR < 50% of baseline for >= 10 consecutive seconds
4. Compute AHI (Apnea-Hypopnea Index) = total events / hours monitored
| AHI | Severity |
|-----|----------|
| < 5 | Normal |
| 5-15 | Mild |
| 15-30 | Moderate |
| > 30 | Severe |
### Output
- Per-event log: type (apnea/hypopnea), start time, duration, BR during event
- Hourly AHI and overall AHI
- Severity classification
- Alert on severe events (consecutive apneas > 30s)
### Clinical Relevance
Pre-screening tool for obstructive sleep apnea (OSA). Provides motivation for clinical polysomnography referral. Not a diagnostic device; informational pre-screen only.
---
## Application 3: Emotional State / Stress Detection
### Input
Heart rate time series from vitals packets at ~1 Hz.
### Algorithm
Heart Rate Variability (HRV) analysis:
1. **RMSSD** (Root Mean Square of Successive Differences):
- Compute successive HR differences within 5-minute windows
- RMSSD = sqrt(mean(diff^2))
- High RMSSD = high vagal tone = relaxed
- Low RMSSD = sympathetic dominance = stressed
2. **LF/HF Ratio** (via FFT on 5-minute HR windows):
- LF band: 0.04-0.15 Hz (sympathetic + parasympathetic)
- HF band: 0.15-0.40 Hz (parasympathetic)
- High LF/HF (> 2.0) = stressed
- Low LF/HF (< 1.0) = relaxed
3. **Stress Score** (0-100):
- `score = 50 * (1 - RMSSD_norm) + 50 * LF_HF_norm`
- Where `RMSSD_norm` = RMSSD / max_expected_RMSSD (capped at 1.0)
- And `LF_HF_norm` = min(LF_HF / 4.0, 1.0)
### Output
- Real-time stress score (0-100)
- RMSSD and LF/HF ratio per window
- ASCII trend chart over hours
- Activity context correlation (motion level vs. stress)
### Validation
- Periods of activity (walking, working) should correlate with higher stress scores
- Quiet rest should show lower scores
- Sleeping should show lowest scores (high HRV, low LF/HF)
---
## Application 4: Gait Analysis / Movement Disorder Detection
### Input
- Motion energy time series from vitals packets
- CSI phase variance from raw CSI frames (0xC5110001)
- Cross-node RSSI from vitals packets
### Algorithm
1. **Cadence Extraction**: FFT on motion_energy within 5-second sliding windows
- Walking cadence: dominant frequency 0.8-2.0 Hz (normal: ~1.0 Hz = 120 steps/min)
- Running: > 2.0 Hz
- Stationary: no dominant peak
2. **Stride Regularity**: Autocorrelation of motion_energy
- Regular walking: strong autocorrelation peak at step period
- Irregularity score = 1 - (peak_height / baseline)
3. **Asymmetry Detection**: Compare motion energy oscillation between two ESP32 nodes
- Symmetric gait: both nodes see similar oscillation period and amplitude
- Asymmetry index = |period_node1 - period_node2| / mean_period
4. **Tremor Detection**: High-frequency phase variance analysis
- Compute phase variance per subcarrier in 2-second windows
- Tremor band: 3-8 Hz component in phase variance time series
- Parkinsonian tremor: 4-6 Hz, resting
- Essential tremor: 5-8 Hz, action
### Output
- Cadence (steps/min)
- Stride regularity score (0-1)
- Asymmetry index (0 = symmetric, 1 = highly asymmetric)
- Tremor score and dominant frequency
- Walking vs. stationary classification
### Validation
Overnight data should show clear stationary periods with no cadence detected. Any walking segments should show cadence in the 0.8-2.0 Hz range.
---
## Application 5: Material/Object Change Detection
### Input
Per-subcarrier amplitude from raw CSI frames (0xC5110001).
### Algorithm
1. **Baseline Establishment** (first 10 minutes or configurable):
- Record mean amplitude per subcarrier (Welford online mean)
- Record null pattern: which subcarriers are below null threshold (amplitude < 2.0)
2. **Change Detection** (sliding 30-second windows):
- Compare current null pattern to baseline
- New nulls appearing = new metal object blocking RF path
- Existing nulls disappearing = metal object removed
- Null position shifted = object moved
- Amplitude change without null change = non-metal material (wood, water, glass)
3. **Material Classification** heuristic:
- Metal: sharp null (amplitude drops to near 0 on specific subcarriers)
- Water/human: broad amplitude reduction across many subcarriers
- Wood/plastic: minimal amplitude change, mostly phase shift
- Glass: frequency-selective (affects higher subcarriers more)
### Output
- Change events with timestamp, type (add/remove/move), affected subcarrier range
- Estimated material category
- Null pattern delta visualization (ASCII)
- Event timeline for monitoring
### Validation
Overnight data has 19% null baseline. Changes in null pattern over the recording period indicate environment changes (doors opening/closing, person entering/leaving).
---
## Application 6: Room Environment Fingerprinting
### Input
- 8-dimensional feature vectors from feature packets (0xC5110003)
- Motion energy and presence score from vitals packets
### Algorithm
1. **Online Clustering** using running k-means (k=5, updateable centroids):
- Each incoming 8-dim feature vector is assigned to nearest centroid
- Centroid updated via exponential moving average (alpha=0.01)
- New cluster created if distance to all centroids exceeds threshold
2. **State Labeling** (heuristic from vitals correlation):
- Cluster with lowest motion_energy = "empty/sleeping"
- Cluster with highest motion_energy = "active/walking"
- Intermediate clusters = "resting", "working", "transitional"
3. **Transition Tracking**:
- Build state transition matrix (from_state -> to_state counts)
- Detect anomalous transitions (rare in historical data)
4. **Daily Profile**:
- Aggregate state durations per hour
- Compare across days for routine detection
### Output
- Current room state and confidence
- State timeline (ASCII)
- Transition matrix
- Daily pattern profile
- Anomaly score (deviation from established daily pattern)
### Validation
Overnight recording should show 2-3 stable clusters corresponding to activity periods at different times. Transitions should be infrequent and correspond to real behavioral changes.

## Implementation
All scripts share common infrastructure:
- ADR-018 binary packet parsing (same as rf-scan.js, mincut-person-counter.js)
- JSONL replay via readline interface
- Live UDP via dgram
- Pure Node.js, no external dependencies
- CLI: `--replay <file>` for offline, `--port <N>` for live, `--json` for programmatic output
| Script | Primary Packets | Key Algorithm |
|--------|----------------|---------------|
| `sleep-monitor.js` | vitals (0xC5110002) | BR/HR window classification |
| `apnea-detector.js` | vitals (0xC5110002) | BR pause detection, AHI scoring |
| `stress-monitor.js` | vitals (0xC5110002) | HRV RMSSD + FFT LF/HF |
| `gait-analyzer.js` | vitals + raw CSI | FFT cadence + phase tremor |
| `material-detector.js` | raw CSI (0xC5110001) | Null pattern baseline + delta |
| `room-fingerprint.js` | feature (0xC5110003) + vitals | Online k-means clustering |
## Consequences
### Positive
- 6 new sensing applications from existing hardware (zero additional cost)
- All offline-capable via JSONL replay (no live hardware needed for development)
- Pure JS, no native dependencies, runs on any platform with Node.js
- Each script is standalone and composable
### Negative
- Vitals accuracy depends on ESP32 CSI quality (RSSI, multipath)
- HRV analysis at 1 Hz HR sampling is coarse compared to ECG
- Material classification is heuristic, not definitive
- Sleep staging without EEG is approximate (consumer-grade accuracy)
### Risks
- Users may misinterpret health-related outputs as clinical diagnoses
- Mitigation: all scripts include disclaimers in output headers

| **Date** | 2026-04-02 |
| **Authors** | ruv |
| **Depends** | ADR-018 (binary frame), ADR-029 (channel hopping), ADR-073 (multi-frequency mesh scan) |
## Context
ADR-073 established multi-frequency mesh scanning: 2 ESP32-S3 nodes hopping across 6 WiFi channels (1, 3, 5, 6, 9, 11) with 9 neighbor WiFi networks as passive illuminators. This ADR defines 5 sensing applications that are **unique to multi-frequency mesh scanning** and impossible with single-channel WiFi sensing.
### Why Multi-Frequency is Required
Single-channel WiFi sensing captures CSI on one frequency (e.g., channel 5 at 2432 MHz). This provides amplitude and phase across ~52-64 OFDM subcarriers within a 20 MHz bandwidth. Multi-frequency mesh scanning extends this to 6 channels spanning 2412-2462 MHz (50 MHz total), with each channel providing independent multipath observations. The applications below exploit the frequency dimension that single-channel sensing cannot access.
### Available Infrastructure

## Decision
Implement 5 multi-frequency-specific sensing applications, each as a standalone Node.js script in `scripts/`.

## Application 1: RF Tomographic Imaging
### Principle
Each WiFi channel "sees" through the room differently because multipath interference patterns are frequency-dependent. A 2 cm path length difference produces a null at 2432 MHz but constructive interference at 2412 MHz. With 6 channels x 2 nodes, we have 12 independent RF path observations through the room.
RF tomography back-projects attenuation along each transmitter-receiver path. Where paths overlap with high attenuation, there is an absorbing object (person, furniture, wall). Where paths show low attenuation, the space is clear.
### Algorithm
```
For each CSI frame:
1. Compute path attenuation = RSSI_free_space - RSSI_measured
2. For each cell in a 10x10 room grid:
a. Compute the cell's distance to the TX->RX line (perpendicular distance)
b. Weight contribution by 1/distance (cells near the path contribute more)
3. Accumulate weighted attenuation across all frames, channels, and node pairs
4. Normalize: cells with high accumulated attenuation = absorbers (people/objects)
```
Uses the Algebraic Reconstruction Technique (ART) for iterative refinement, or simple backprojection for real-time display.
### Resolution
- Theoretical: ~lambda/2 = 6 cm (at 2.4 GHz)
- Practical with 2 nodes: ~20 cm (limited by node geometry)
- Frequency diversity gain: sqrt(6) improvement over single-channel = ~2.4x
### Why Single-Channel Cannot Do This
Single-channel provides only 1 frequency observation per path. Frequency-selective fading means a single channel may show zero attenuation through a person (if the path happens to be at a constructive interference point). Multiple channels provide independent attenuation measurements through the same spatial path, enabling reliable detection.
### Script
`scripts/rf-tomography.js`

## Application 2: Passive Bistatic Radar
### Principle
Neighbor WiFi APs transmit continuously and uncontrollably. The ESP32 nodes capture CSI from these transmissions, which includes phase and amplitude modulated by objects in the room. Each neighbor AP acts as a free "illuminator of opportunity" at a known position and frequency.
This is the same principle used by military passive radar systems (e.g., the Ukrainian Kolchuga, Czech VERA-NG) that use FM radio and TV transmitters to detect aircraft without emitting any signals themselves. Here we use WiFi APs instead of broadcast towers, and detect people instead of aircraft.
### Algorithm
```
For each neighbor AP (identified by BSSID/channel):
1. Track CSI phase progression across consecutive frames
2. Compute Doppler shift: fd = d(phase)/dt / (2*pi)
- Positive Doppler = target moving toward the AP
- Negative Doppler = target moving away
3. Compute range from subcarrier phase slope:
- tau = d(phase)/d(subcarrier_freq) / (2*pi)
- range = c * tau (where c = speed of light)
4. Build range-Doppler map per AP
5. Fuse multi-static detections:
- Each AP provides a range ellipse (locus of constant TX->target->RX delay)
- Intersection of 3+ ellipses = target position
```
### Multi-Static Geometry
With 3+ neighbor APs as transmitters and 2 ESP32 receivers, we have 6+ bistatic pairs. Each pair constrains the target to an ellipse. The intersection provides 2D position.
```
AP1 (ch5) AP2 (ch11)
\ /
\ TARGET /
\ /|\ /
\ / | \ /
ESP32_1 ---*--+--*--- ESP32_2
/ \ | / \
/ \|/ \
/ TARGET \
/ \
AP3 (ch3) AP4 (ch9)
```
### Why Single-Channel Cannot Do This
Single-channel only captures CSI from APs on that one channel. With channel 5, you see ruv.net and Cohen-Guest, but miss COGECO-21B20 (ch11), conclusion mesh (ch3), NETGEAR72 (ch9). Multi-frequency scanning captures illumination from all 9 APs across 6 channels, providing the geometric diversity needed for position triangulation.
### Script
`scripts/passive-radar.js`

## Application 3: Frequency-Selective Material Classification
### Principle
Different materials interact with 2.4 GHz WiFi signals differently, and critically, their absorption/reflection varies with frequency:
| Material | Attenuation Pattern | Frequency Dependence |
|----------|--------------------|--------------------|
| Metal | Total reflection, deep null | Frequency-flat (blocks all equally) |
| Water/Human body | Strong absorption | Increases with frequency (dielectric loss ~ f^2) |
| Wood | Mild attenuation | Increases with frequency (moisture content) |
| Glass | Low attenuation | Nearly frequency-flat |
| Drywall | Low-moderate attenuation | Slight frequency dependence |
| Concrete | Moderate-high attenuation | Increases with frequency |
### Algorithm
```
For each subcarrier index i across all channels:
1. Measure attenuation A(i, ch) on each channel
2. Compute frequency selectivity:
- Flat ratio = std(A across channels) / mean(A across channels)
- Slope = linear regression of A vs frequency
3. Classify:
- Flat ratio < 0.1 AND high attenuation -> Metal
- Flat ratio < 0.1 AND low attenuation -> Glass/Air
- Positive slope (A increases with freq) AND high A -> Water/Human
- Positive slope AND moderate A -> Wood
- High variance across channels -> Complex scatterer
```
### Physics Basis
At 2.4 GHz, water's complex permittivity is epsilon_r = 77 - j10. The imaginary component (loss) increases with frequency within the WiFi band. Metal is a perfect conductor regardless of frequency. Glass (epsilon_r ~ 6 - j0.1) has negligible loss at all WiFi frequencies.
The 50 MHz span (2412-2462 MHz) is only ~2% of the carrier frequency, but this is sufficient to detect the frequency-dependent absorption signature of water-bearing materials (human body, wet wood, potted plants) versus frequency-flat materials (metal, glass).
### Why Single-Channel Cannot Do This
Material classification requires measuring how attenuation varies with frequency. A single channel provides only one frequency point -- there is no frequency axis to measure against. Multi-frequency scanning provides 6 frequency points spanning 50 MHz, enabling slope and variance computation.
### Script
`scripts/material-classifier.js`
---
## Application 4: Through-Wall Motion Detection
### Principle
Lower WiFi frequencies penetrate walls better than higher frequencies. At 2.4 GHz, wall attenuation for a standard drywall+stud partition is approximately:
| Channel | Freq (MHz) | Drywall Loss (dB) | Concrete Loss (dB) |
|---------|------------|-------------------|-------------------|
| 1 | 2412 | 2.5 | 8.0 |
| 6 | 2437 | 2.6 | 8.3 |
| 11 | 2462 | 2.7 | 8.6 |
The absolute differences are small (~0.2 dB), but with 6 channels we can:
1. **Baseline the wall's frequency-dependent attenuation profile** during a calibration period (no one behind the wall)
2. **Detect changes above baseline** that indicate motion behind the wall
3. **Weight lower channels more heavily** since they have better through-wall SNR
4. **Cross-validate** across channels: real through-wall motion appears on all channels (with frequency-dependent amplitude), while interference/noise typically appears on only one channel
### Algorithm
```
Calibration phase (60 seconds, no motion behind wall):
For each channel ch:
baseline_mean[ch] = mean(CSI amplitude over calibration)
baseline_std[ch] = std(CSI amplitude over calibration)
Detection phase:
For each frame on channel ch:
1. Compute deviation = |current_amplitude - baseline_mean[ch]| / baseline_std[ch]
2. Channel weight = f(penetration_quality[ch])
3. Per-channel score = deviation * weight
Fused score = weighted sum across channels
Alert if fused_score > threshold for N consecutive frames
```
### Why Single-Channel Cannot Do This
Single-channel through-wall detection suffers from high false-positive rates because it cannot distinguish wall effects from motion. With multi-frequency, we can:
1. Characterize the wall's frequency response during calibration
2. Subtract the wall effect per channel
3. Cross-validate detections across channels (real motion is coherent across frequencies; noise is not)
The frequency diversity provides a ~2.4x improvement in detection SNR (sqrt(6) independent observations).
### Script
`scripts/through-wall-detector.js`
---
## Application 5: Device Fingerprinting via RF Emissions
### Principle
Every electronic device has unique RF characteristics visible in the WiFi spectrum. When a device transmits (or even when its internal oscillators radiate EMI), it modulates nearby WiFi signals in device-specific ways:
- **WiFi APs**: each AP has unique transmit power, phase noise, and clock drift characteristics
- **Printers**: the HP M255 LaserJet creates specific subcarrier patterns when printing (motor EMI)
- **Microwave ovens**: 2.45 GHz magnetron radiates across channels 8-11, creating distinctive wideband interference
- **Bluetooth devices**: 2.4 GHz frequency-hopping creates transient spikes across channels
### Algorithm
```
Learning phase:
For each known device (from WiFi scan SSID/BSSID correlation):
1. Record CSI patterns when device is active vs inactive
2. Compute per-channel signature:
- Mean amplitude profile across subcarriers
- Variance profile (active devices increase variance on specific subcarriers)
- Phase noise characteristics
3. Store signature as device fingerprint
Detection phase:
For each analysis window:
1. Compute current CSI profile per channel
2. Correlate against stored fingerprints
3. Report device activity: "HP printer active (confidence 0.87)"
```
### Multi-Frequency Advantage
Different devices affect different channels:
- HP printer (ch5): affects subcarriers 20-40 on channel 5 during print jobs
- NETGEAR72 router (ch9): creates clock-drift correlated phase patterns on channel 9
- Microwave: broadband interference strongest on channels 9-11
Single-channel sensing only sees devices that affect that one channel. Multi-frequency scanning observes the full 2412-2462 MHz band, detecting device activity regardless of which channel the device operates on.
### Script
`scripts/device-fingerprint.js`
---
## Implementation
### Shared Infrastructure
All 5 scripts share common infrastructure:
| Component | Detail |
|-----------|--------|
| Packet format | ADR-018 binary (UDP) or .csi.jsonl (replay) |
| IQ parsing | `parseIqHex()` for JSONL, `parseCSIFrame()` for binary UDP |
| Channel assignment | From binary freq field, or simulated round-robin for legacy JSONL |
| Node positions | Configurable, default: Node 1 at (0,0), Node 2 at (3,0) meters |
| Visualization | ASCII Unicode block characters and box drawing |
### Scripts
| Script | Application | Lines | Key Algorithm |
|--------|------------|-------|---------------|
| `scripts/rf-tomography.js` | RF Tomographic Imaging | ~500 | ART backprojection |
| `scripts/passive-radar.js` | Passive Bistatic Radar | ~500 | Range-Doppler + multi-static fusion |
| `scripts/material-classifier.js` | Material Classification | ~450 | Frequency-selective attenuation analysis |
| `scripts/through-wall-detector.js` | Through-Wall Detection | ~400 | Baselined multi-channel anomaly detection |
| `scripts/device-fingerprint.js` | Device Fingerprinting | ~450 | Per-channel signature correlation |
### Data Requirements
- **Live mode**: UDP port 5006, 2 ESP32 nodes channel-hopping per ADR-073
- **Replay mode**: `--replay <file.csi.jsonl>` with overnight recordings
- **Calibration**: through-wall detector requires 60s calibration with `--calibrate`
## Performance Targets
| Application | Latency | Update Rate | Accuracy Target |
|-------------|---------|-------------|-----------------|
| RF Tomography | <100ms per frame | 1 Hz image update | 20 cm spatial resolution |
| Passive Radar | <200ms per frame | 2 Hz range-Doppler | 1 m range, 0.1 m/s velocity |
| Material Classification | <500ms per window | 0.5 Hz classification | 70% correct material ID |
| Through-Wall Detection | <100ms per frame | 2 Hz detection | 90% true positive, <10% false positive |
| Device Fingerprinting | <1s per window | 0.2 Hz activity update | 80% correct device ID |
## Risks
### Limited Frequency Span
The 50 MHz span (2412-2462 MHz) is only 2% of the carrier frequency. Material classification accuracy depends on the attenuation slope being measurable within this narrow range. Mitigation: use long averaging windows (5-10 seconds) to improve SNR of frequency-dependent measurements.
### Node Geometry
2 nodes provide limited spatial diversity for tomographic imaging. The backprojection is essentially 1D along the node-to-node axis, with poor resolution perpendicular to it. Mitigation: neighbor APs provide additional geometric diversity for passive radar mode.
### Legacy Data Compatibility
Overnight recordings (`data/recordings/overnight-*.csi.jsonl`) were captured before multi-frequency scanning was deployed and lack channel/frequency fields. Scripts simulate channel assignment for replay. Full multi-frequency data requires re-recording with channel hopping enabled.
### Phase Calibration
Passive radar requires accurate phase tracking across consecutive frames. ESP32 CSI phase includes a random offset per channel hop that must be removed. Mitigation: use phase-difference between consecutive frames rather than absolute phase.
## Alternatives Considered
1. **5 GHz multi-frequency**: rejected -- no 5 GHz APs visible in environment, no free illuminators.
2. **UWB (ultra-wideband)**: rejected -- ESP32-S3 does not support UWB. Would require additional hardware (DW1000/DW3000 modules).
3. **Dedicated radar hardware**: rejected -- multi-frequency WiFi sensing achieves similar capabilities using existing infrastructure at zero additional cost.

# ADR-079: Camera Ground-Truth Training Pipeline
- **Status**: Accepted
- **Date**: 2026-04-06
- **Deciders**: ruv
- **Relates to**: ADR-072 (WiFlow Architecture), ADR-070 (Self-Supervised Pretraining), ADR-071 (ruvllm Training Pipeline), ADR-024 (AETHER Contrastive), ADR-064 (Multimodal Ambient Intelligence), ADR-075 (MinCut Person Separation)
## Context
WiFlow (ADR-072) currently trains without ground-truth pose labels, using proxy poses
generated from presence/motion heuristics. This produces a PCK@20 of only 2.5% — far
below the 30-50% achievable with supervised training. The fundamental bottleneck is the
absence of spatial keypoint labels.
Academic WiFi pose estimation systems (Wi-Pose, Person-in-WiFi 3D, MetaFi++) all train
with synchronized camera ground truth and achieve PCK@20 of 40-85%. They discard the
camera at deployment — the camera is a training-time teacher, not a runtime dependency.
ADR-064 already identified this: *"Record CSI + mmWave while performing signs with a
camera as ground truth, then deploy camera-free."* This ADR specifies the implementation.
### Current Training Pipeline Gap
```
Current: CSI amplitude → WiFlow → 17 keypoints (proxy-supervised, PCK@20 = 2.5%)
Heuristic proxies:
- Standing skeleton when presence > 0.3
- Limb perturbation from motion energy
- No spatial accuracy
```
### Target Pipeline
```
Training: CSI amplitude ──→ WiFlow ──→ 17 keypoints (camera-supervised, PCK@20 target: 35%+)
Laptop camera ──→ MediaPipe ──→ 17 COCO keypoints (ground truth)
(time-synchronized, 30 fps)
Deploy: CSI amplitude ──→ WiFlow ──→ 17 keypoints (camera-free, trained model only)
```
## Decision
Build a camera ground-truth collection and training pipeline using the laptop webcam
as a teacher signal. The camera is used **only during training data collection** and is
not required at deployment.

```
### Component 1: `scripts/collect-ground-truth.py`
Single Python script that orchestrates synchronized capture from the laptop camera
and the ESP32 CSI stream.
**Dependencies:** `mediapipe`, `opencv-python`, `requests` (all pip-installable, no GPU)
**Capture flow:**
```python
# Pseudocode
camera = cv2.VideoCapture(0) # Laptop webcam
sensing_api = "http://localhost:3000" # Sensing server
# Start CSI recording via existing API
requests.post(f"{sensing_api}/api/v1/recording/start")
while recording:
frame = camera.read()
t = time.time_ns() # Nanosecond timestamp
# MediaPipe Pose: 33 landmarks → map to 17 COCO keypoints
result = mp_pose.process(frame)
keypoints_17 = map_mediapipe_to_coco(result.pose_landmarks)
confidence = mean(landmark.visibility for relevant landmarks)
# Write to ground-truth JSONL (one line per frame)
write_jsonl({
"ts_ns": t,
"keypoints": keypoints_17, # [[x,y], ...] normalized [0,1]
"confidence": confidence, # 0-1, used for loss weighting
"n_visible": count(visibility > 0.5),
})
# Optional: show live preview with skeleton overlay
if preview:
draw_skeleton(frame, keypoints_17)
cv2.imshow("Ground Truth", frame)
# Stop CSI recording
requests.post(f"{sensing_api}/api/v1/recording/stop")
```
**MediaPipe → COCO keypoint mapping:**
| COCO Index | Joint | MediaPipe Index |
|------------|-------|-----------------|
| 0 | Nose | 0 |
| 1 | Left Eye | 2 |
| 2 | Right Eye | 5 |
| 3 | Left Ear | 7 |
| 4 | Right Ear | 8 |
| 5 | Left Shoulder | 11 |
| 6 | Right Shoulder | 12 |
| 7 | Left Elbow | 13 |
| 8 | Right Elbow | 14 |
| 9 | Left Wrist | 15 |
| 10 | Right Wrist | 16 |
| 11 | Left Hip | 23 |
| 12 | Right Hip | 24 |
| 13 | Left Knee | 25 |
| 14 | Right Knee | 26 |
| 15 | Left Ankle | 27 |
| 16 | Right Ankle | 28 |
### Component 2: Time Alignment (`scripts/align-ground-truth.js`)
CSI frames arrive at ~100 Hz with server-side timestamps. Camera keypoints arrive at
~30 fps with client-side timestamps. Alignment is needed because:
1. Camera and sensing server clocks differ (typically < 50ms on LAN)
2. CSI is aggregated into 20-frame windows for WiFlow input
3. Ground-truth keypoints must be averaged over the same window
**Alignment algorithm:**
```
For each CSI window W_i (20 frames, ~200ms at 100Hz):
t_start = W_i.first_frame.timestamp
t_end = W_i.last_frame.timestamp
# Find all camera keypoints within this time window
matching_keypoints = [k for k in camera_data if t_start <= k.ts <= t_end]
if len(matching_keypoints) >= 3: # At least 3 camera frames per window
# Average keypoints, weighted by confidence
avg_keypoints = weighted_mean(matching_keypoints, weights=confidences)
avg_confidence = mean(confidences)
paired_dataset.append({
csi_window: W_i.amplitudes, # [128, 20] float32
keypoints: avg_keypoints, # [17, 2] float32
confidence: avg_confidence, # scalar
n_camera_frames: len(matching_keypoints),
})
```
**Clock sync strategy:**
- NTP is sufficient (< 20ms error on LAN)
- The 200ms CSI window is 10x larger than typical clock drift
- For tighter sync: use a handclap/jump as a sync marker — visible spike in both
CSI motion energy and camera skeleton velocity. Auto-detect and align.
**Output:** `data/recordings/paired-{timestamp}.jsonl` — one line per paired sample:
```json
{"csi": [128x20 flat], "kp": [[0.45,0.12], ...], "conf": 0.92, "ts": 1775300000000}
```
### Component 3: Supervised Training (`scripts/train-wiflow-supervised.js`)
Extends the existing `train-ruvllm.js` pipeline with a supervised phase.
**Phase 1: Contrastive Pretrain (reuse ADR-072)**
- Same as existing: temporal + cross-node triplets
- Learns CSI representation without labels
- 50 epochs, ~5 min on laptop
**Phase 2: Supervised Keypoint Regression (NEW)**
- Load paired dataset from Component 2
- Loss: confidence-weighted SmoothL1 on keypoints
```
L_supervised = (1/N) * sum_i [ conf_i * SmoothL1(pred_i, gt_i, beta=0.05) ]
```
- Only train on samples where `conf > 0.5` (discard frames where MediaPipe lost tracking)
- Learning rate: 1e-4 with cosine decay
- 200 epochs, ~15 min on laptop CPU (1.8M params, no GPU needed)
**Phase 3: Refinement with Bone Constraints**
- Fine-tune with combined loss:
```
L = L_supervised + 0.3 * L_bone + 0.1 * L_temporal
L_bone = (1/14) * sum_b (bone_len_b - prior_b)^2 # ADR-072 bone priors
L_temporal = SmoothL1(kp_t, kp_{t-1}) # Temporal smoothness
```
- 50 epochs at lower LR (1e-5)
- Tighten bone constraint weight from 0.3 → 0.5 over epochs
**Phase 4: Quantization + Export**
- Reuse ruvllm TurboQuant: float32 → int8 (4x smaller, ~881 KB)
- Export via SafeTensors for cross-platform deployment
- Validate quantized model PCK@20 within 2% of full-precision
### Component 4: Evaluation Script (`scripts/eval-wiflow.js`)
Measure actual PCK@20 using held-out paired data (20% split).
```
PCK@k = (1/N) * sum_i [ (||pred_i - gt_i|| < k * torso_length) ? 1 : 0 ]
```
**Metrics reported:**
| Metric | Description | Target |
|--------|-------------|--------|
| PCK@20 | % of keypoints within 20% torso length | > 35% |
| PCK@50 | % within 50% torso length | > 60% |
| MPJPE | Mean per-joint position error (pixels) | < 40px |
| Per-joint PCK | Breakdown by joint (wrists are hardest) | Report all 17 |
| Inference latency | Single window prediction time | < 50ms |
### Optimization Strategy
#### O1: Curriculum Learning
Train easy poses first, hard poses later:
| Stage | Epochs | Data Filter | Rationale |
|-------|--------|-------------|-----------|
| 1 | 50 | `conf > 0.9`, standing only | Establish stable skeleton baseline |
| 2 | 50 | `conf > 0.7`, low motion | Add sitting, subtle movements |
| 3 | 50 | `conf > 0.5`, all poses | Full dataset including occlusions |
| 4 | 50 | All data, with augmentation | Robustness via noise injection |
#### O2: Data Augmentation (CSI domain)
Augment CSI windows to increase effective dataset size without collecting more data:
| Augmentation | Implementation | Expected Gain |
|-------------|----------------|---------------|
| Time shift | Roll CSI window by ±2 frames | +30% data |
| Amplitude noise | Gaussian noise, sigma=0.02 | Robustness |
| Subcarrier dropout | Zero 10% of subcarriers randomly | Robustness |
| Temporal flip | Reverse window + reverse keypoint velocity | +100% data |
| Multi-node mix | Swap node CSI, keep same-time keypoints | Cross-node generalization |
#### O3: Knowledge Distillation from MediaPipe
Instead of raw keypoint regression, distill MediaPipe's confidence and heatmap
information:
```
L_distill = KL_div(softmax(wifi_heatmap / T), softmax(camera_heatmap / T))
```
- Temperature T=4 for soft targets (transfers inter-joint relationships)
- WiFlow predicts a 17-channel heatmap [17, H, W] instead of direct [17, 2]
- Argmax for final keypoint extraction
- **Trade-off:** Adds ~200K params for heatmap decoder, but improves spatial precision
#### O4: Active Learning Loop
Identify which poses the model is worst at and collect more data for those:
```
1. Train initial model on first collection session
2. Run inference on new CSI data, compute prediction entropy
3. Flag high-entropy windows (model is uncertain)
4. During next collection, the preview overlay highlights these moments:
"Hold this pose — model needs more examples"
5. Re-train with augmented dataset
```
Expected: 2-3 active learning iterations reach saturation.
#### O6: Subcarrier Selection (ruvector-solver)
Variance-based top-K subcarrier selection, equivalent to ruvector-solver's sparse
interpolation (114→56). Removes noise/static subcarriers before training:
```
For each subcarrier d in [0, dim):
variance[d] = mean over samples of temporal_variance(csi[d, :])
Select top-K by variance (K = dim * 0.5)
```
**Validated:** 128 → 56 subcarriers (56% input reduction), proportional model size reduction.
#### O7: Attention-Weighted Subcarriers (ruvector-attention)
Compute per-subcarrier attention weights based on temporal energy correlation with
ground-truth keypoint motion. High-energy subcarriers that covary with skeleton
movement get amplified:
```
For each subcarrier d:
energy[d] = sum of squared first-differences over time
weight[d] = softmax(energy, temperature=0.1)
Apply: csi[d, :] *= weight[d] * dim (mean weight = 1)
```
**Validated:** Top-5 attention subcarriers identified automatically per dataset.
#### O8: Stoer-Wagner MinCut Person Separation (ruvector-mincut / ADR-075)
JS implementation of the Stoer-Wagner algorithm for person separation in CSI, equivalent
to `DynamicPersonMatcher` in `wifi-densepose-train/src/metrics.rs`. Builds a subcarrier
correlation graph and finds the minimum cut to identify person-specific subcarrier clusters:
```
1. Build dim×dim Pearson correlation matrix across subcarriers
2. Run Stoer-Wagner min-cut on correlation graph
3. Partition subcarriers into person-specific groups
4. Train per-partition models for multi-person scenarios
```
**Validated:** Stoer-Wagner executes on 56-dim graph, identifies partition boundaries.
#### O9: Multi-SPSA Gradient Estimation
Average over K=3 random perturbation directions per gradient step. Reduces variance
by sqrt(K) = 1.73x compared to single SPSA, at 3x forward pass cost (net win for
convergence quality):
```
For k in 1..K:
delta_k = random ±1 per parameter
grad_k = (loss(w + eps*delta_k) - loss(w - eps*delta_k)) / (2*eps*delta_k)
grad = mean(grad_1, ..., grad_K)
```
#### O10: Mac M4 Pro Training via Tailscale
Training runs on Mac Mini M4 Pro (16-core GPU, ARM NEON SIMD) via Tailscale SSH,
using ruvllm's native Node.js SIMD ops:
| | Windows (CPU) | Mac M4 Pro |
|---|---|---|
| Node.js | v24.12.0 (x86) | v25.9.0 (ARM) |
| SIMD | SSE4/AVX2 | NEON |
| Cores | Consumer laptop | 12P + 4E cores |
| Training | Slow (minutes/epoch) | Fast (seconds/epoch) |
#### O5: Cross-Environment Transfer
Train on one room, deploy in another:
| Strategy | Implementation |
|----------|---------------|
| Room-invariant features | Normalize CSI by running mean/variance |
| LoRA adapters | Train a 4-rank LoRA per room (ADR-071) — 7.3 KB each |
| Few-shot calibration | 2 min of camera data in new room → fine-tune LoRA only |
| AETHER embeddings | Use contrastive room-independent features (ADR-024) as input |
The LoRA approach is most practical: ship a base model + collect 2 min of calibration
data per new room using the laptop camera.
### Data Collection Protocol
Recommended collection sessions per room:
| Session | Duration | Activity | People | Total CSI Frames |
|---------|----------|----------|--------|-----------------|
| 1. Baseline | 5 min | Empty + 1 person entry/exit | 0-1 | 30,000 |
| 2. Standing poses | 5 min | Stand, arms up/down/sides, turn | 1 | 30,000 |
| 3. Sitting | 5 min | Sit, type, lean, stand up/sit down | 1 | 30,000 |
| 4. Walking | 5 min | Walk paths across room | 1 | 30,000 |
| 5. Mixed | 5 min | Varied activities, transitions | 1 | 30,000 |
| 6. Multi-person | 5 min | 2 people, varied activities | 2 | 30,000 |
| **Total** | **30 min** | | | **180,000** |
At 20-frame windows: **9,000 paired training samples** per 30-min session.
With augmentation (O2): **~27,000 effective samples**.
Camera placement: position laptop so the camera has a clear view of the sensing area.
The camera FOV should cover the same space the ESP32 nodes cover.
### File Structure
```
scripts/
collect-ground-truth.py # Camera capture + MediaPipe + CSI sync
align-ground-truth.js # Time-align CSI windows with camera keypoints
train-wiflow-supervised.js # Supervised training pipeline
eval-wiflow.js # PCK evaluation on held-out data
data/
ground-truth/ # Raw camera keypoint captures
gt-{timestamp}.jsonl
paired/ # Aligned CSI + keypoint pairs
paired-{timestamp}.jsonl
models/
wiflow-supervised/ # Trained model outputs
wiflow-v1.safetensors
wiflow-v1-int8.safetensors
training-log.json
eval-report.json
```
### Privacy Considerations
- Camera frames are processed **locally** by MediaPipe — no cloud upload
- Raw video is **never saved** — only extracted keypoint coordinates are stored
- The `.jsonl` ground-truth files contain only `[x,y]` joint coordinates, not images
- The trained model runs on CSI only — no camera data leaves the laptop
- Users can delete `data/ground-truth/` after training; the model is self-contained
## Consequences
### Positive
- **10-20x accuracy improvement**: PCK@20 from 2.5% → 35%+ with real supervision
- **Reuses existing infrastructure**: sensing server recording API, ruvllm training, SafeTensors
- **No new hardware**: laptop webcam + existing ESP32 nodes
- **Privacy preserved at deployment**: camera only needed during 30-min training session
- **Incremental**: can improve with more collection sessions + active learning
- **Distributable**: trained model weights can be shared on HuggingFace (ADR-070)
### Negative
- **Camera placement matters**: must see the same area ESP32 nodes sense
- **Single-room models**: need LoRA calibration per room (2 min + camera)
- **MediaPipe limitations**: occlusion, side views, multiple people reduce keypoint quality
- **Time sync**: NTP drift can misalign frames (mitigated by 200ms windows)
### Risks
| Risk | Probability | Impact | Mitigation |
|------|-------------|--------|------------|
| MediaPipe keypoints too noisy | Low | Medium | Filter by confidence; MediaPipe is robust indoors |
| Clock drift > 100ms | Low | High | Add handclap sync marker detection |
| Single camera can't see all poses | Medium | Medium | Position camera centrally; collect from 2 angles |
| Model overfits to one room | High | Medium | LoRA adapters + AETHER normalization (O5) |
| Insufficient data (< 5K pairs) | Low | High | Augmentation (O2) + active learning (O4) |
## Implementation Plan
| Phase | Task | Effort | Status |
|-------|------|--------|--------|

## Baseline Benchmark
Proxy-pose baseline (no camera supervision, standing skeleton heuristic):
```
PCK@10: 11.8%
PCK@20: 35.3%
PCK@50: 94.1%
MPJPE: 0.067
Latency: 0.03ms/sample
```
Per-joint PCK@20: upper body (nose, shoulders, wrists) at 0% — proxy has no spatial
accuracy for these. Camera supervision targets these joints specifically.

# ADR-080: QE Analysis Remediation Plan
- **Status:** Proposed
- **Date:** 2026-04-06
- **Source:** [QE Analysis Gist (2026-04-05)](https://gist.github.com/proffesor-for-testing/a6b84d7a4e26b7bbef0cf12f932925b7)
- **Full Reports:** [proffesor-for-testing/RuView `qe-reports` branch](https://github.com/proffesor-for-testing/RuView/tree/qe-reports/docs/qe-reports)
## Context
An 8-agent QE swarm analyzed ~305K lines across Rust, Python, C firmware, and TypeScript on 2026-04-05. The overall score was **55/100 (C+) — Quality Gate FAILED**. This ADR captures the findings and establishes a remediation plan.
## Decision
Address the 15 prioritized issues from the QE analysis in three waves: P0 (immediate), P1 (this sprint), P2 (this quarter).
## P0 — Fix Immediately
### 1. Rate Limiter Bypass (Security HIGH)
- **Location:** `archive/v1/src/middleware/rate_limit.py:200-206`
- **Problem:** Trusts `X-Forwarded-For` without validation. Any client bypasses rate limits via header spoofing.
- **Fix:** Validate forwarded headers against trusted proxy list, or use connection IP directly.
### 2. Exception Details Leaked in Responses (Security HIGH)
- **Location:** `archive/v1/src/api/routers/pose.py:140`, `stream.py:297`, +5 endpoints
- **Problem:** Stack traces visible regardless of environment.
- **Fix:** Wrap with generic error responses in production; log details server-side only.
### 3. WebSocket JWT in URL (Security HIGH, CWE-598)
- **Location:** `archive/v1/src/api/routers/stream.py:74`, `archive/v1/src/middleware/auth.py:243`
- **Problem:** Tokens in query strings visible in logs/proxies/browser history.
- **Fix:** Use WebSocket subprotocol or first-message auth pattern.
### 4. Rust Tests Not in CI
- **Problem:** 2,618 tests across 153K lines of Rust — zero run in any GitHub Actions workflow. Regressions ship undetected.
- **Fix:** Add `cargo test --workspace --no-default-features` to CI. 1-2 hour task.
### 5. WebSocket Path Mismatch (Bug)
- **Location:** `ui/mobile/src/services/ws.service.ts:104` constructs `/ws/sensing`, but `constants/websocket.ts:1` defines `WS_PATH = '/api/v1/stream/pose'`.
- **Problem:** Mobile WebSocket silently fails.
- **Fix:** Align paths. Verify which endpoint the server actually serves.
## P1 — Fix This Sprint
| # | Issue | Location | Impact |
|---|-------|----------|--------|
| 6 | God file: 4,846 lines, CC=121 | `sensing-server/src/main.rs` | Untestable monolith |
| 7 | O(L×V) voxel scan per frame | `ruvsense/tomography.rs:345-383` | ~10ms wasted; use DDA ray march |
| 8 | Sequential neural inference | `wifi-densepose-nn inference.rs:334-336` | 2-4× GPU latency penalty |
| 9 | 720 `.unwrap()` in Rust | Workspace-wide | Each = potential panic in RT paths |
| 10 | 112KB alloc/frame in Python | `csi_processor.py:412-414` | Deque→list→numpy every frame |
## P2 — Fix This Quarter
| # | Issue | Impact |
|---|-------|--------|
| 11 | 11/12 Python modules have zero unit tests (12,280 LOC) | Services, middleware, DB untested |
| 12 | Firmware at 19% coverage (WASM runtime, OTA, swarm) | Security-critical code untested |
| 13 | MAT screen auto-falls back to simulated data | Disaster responders could monitor fake data |
| 14 | Token blacklist never consulted during auth | Revoked tokens remain valid |
| 15 | 50ms frame budget never benchmarked | Real-time requirement unverified |
## Bright Spots
- 79 ADRs (exceptional governance)
- Witness bundle system (ADR-028) with SHA-256 proof
- 2,618 Rust tests with mathematical rigor
- Daily security scanning (Bandit, Semgrep, Safety)
- Ed25519 WASM signature verification on firmware
- Clean mobile state management with good test coverage
## Full QE Reports (9 files, 4,914 lines)
| Report | What it covers |
|--------|---------------|
| `EXECUTIVE-SUMMARY.md` | Top-level synthesis with all scores and priority matrix |
| `00-qe-queen-summary.md` | Master coordination, quality posture, test pyramid |
| `01-code-quality-complexity.md` | Cyclomatic complexity, code smells, top 20 hotspots |

## Consequences
- **P0 fixes** eliminate 3 security vulnerabilities and 2 functional bugs
- **P1 fixes** improve performance, reliability, and maintainability
- **P2 fixes** close coverage gaps and harden the system for production
- Target score improvement: 55 → 75+ after P0+P1 completion

# ADR-081: Adaptive CSI Mesh Firmware Kernel
| Field | Value |
|-------------|-----------------------------------------------------------------------|
| **Status** | Accepted — Layers 1/2/3/4/5 implemented and host-tested; mesh RX path and Ed25519 signing tracked as Phase 3.5 polish |
| **Date** | 2026-04-19 |
| **Authors** | ruv |
| **Depends** | ADR-018, ADR-028, ADR-029, ADR-031, ADR-032, ADR-039, ADR-066, ADR-073 |
## Context
RuView's firmware grew bottom-up. ADR-018 defined a binary CSI frame, ADR-029
added channel hopping and TDM, ADR-039 added a tiered edge-intelligence
pipeline, ADR-040 added programmable WASM modules, ADR-060 added per-node
channel and MAC overrides, ADR-066 added a swarm bridge to a coordinator, and
ADR-073 added multifrequency mesh scanning. Each one was a sound local
decision. Together they produced a firmware that works on ESP32-S3 but is
**implicitly coupled** to that chipset through `csi_collector.c` calling
`esp_wifi_*` directly and through hard-coded assumptions about the WiFi driver
callback shape.
This is a problem for three reasons:
1. **Portability.** Espressif exposes CSI through an official driver API. On
locked Broadcom and Cypress chips, projects like Nexmon achieve the same
thing by patching the firmware blob — but only for specific chip and
firmware build combinations. Future RuView nodes will likely span both
models plus eventually a custom silicon path. Today, none of the modules
above can be reused unchanged on any non-ESP32 chip.
2. **Adaptivity.** The current firmware reacts to configuration, not to
conditions. Channel hop intervals, edge tier, vitals cadence, top-K
subcarriers, fall threshold, and power duty are all read from NVS at boot
and never revisited. There is no closed-loop control: if a channel becomes
congested, if motion spikes, if inter-node coherence drops, or if the
environment is stable enough to coast at lower cadence, nothing changes
onboard. The adaptive classifier in `wifi-densepose-sensing-server` does
adapt — but only on the host side, after the data has already traversed the
network at fixed rate.
3. **Mesh as an afterthought.** ADR-029 wired in a `TdmCoordinator` and ADR-066
added a swarm bridge to a Cognitum Seed, but there is no first-class node
role enumeration (anchor / observer / fusion-relay / coordinator), no
role-assignment protocol, no `FEATURE_DELTA` message type, no
coordinator-driven channel plan, and no automatic role re-election when a
node drops. Multi-node deployments today are stitched together by manual
per-node NVS provisioning.
The hard truth is that the firmware hack — getting raw CSI off a radio — is
not the moat. The moat is **adaptive control, multi-node fusion, compact
state encoding, persistent memory, and contrastive reasoning on top of the
radio layer**. The current architecture does not name those layers, so they
get reinvented inline by every new ADR.
## Decision
Adopt a **5-layer adaptive RF sensing kernel** as the canonical RuView
firmware architecture, and refactor the existing modules to fit underneath
it. The five layers, top to bottom:
```
┌─────────────────────────────────────────────────────────────────────────┐
│ Layer 5 — Rust handoff │
│ Two streams only: feature_state (default) and debug_csi_frame (gated) │
└─────────────────────────────────────────────────────────────────────────┘
┌─────────────────────────────────────────────────────────────────────────┐
│ Layer 4 — On-device feature extraction │
│ 100 ms motion, 1 s respiration, 5 s baseline windows │
│ Emits compact rv_feature_state_t (magic 0xC5110006) │
└─────────────────────────────────────────────────────────────────────────┘
┌─────────────────────────────────────────────────────────────────────────┐
│ Layer 3 — Mesh sensing plane │
│ Roles: Anchor / Observer / Fusion relay / Coordinator │
│ Messages: TIME_SYNC, ROLE_ASSIGN, CHANNEL_PLAN, CALIBRATION_START, │
│ FEATURE_DELTA, HEALTH, ANOMALY_ALERT │
└─────────────────────────────────────────────────────────────────────────┘
┌─────────────────────────────────────────────────────────────────────────┐
│ Layer 2 — Adaptive controller │
│ Fast loop ~200 ms — packet rate, active probing │
│ Medium loop ~1 s — channel selection, role changes │
│ Slow loop ~30 s — baseline recalibration │
└─────────────────────────────────────────────────────────────────────────┘
┌─────────────────────────────────────────────────────────────────────────┐
│ Layer 1 — Radio Abstraction Layer (rv_radio_ops_t vtable) │
│ ESP32 binding, future Nexmon binding, future custom silicon binding │
└─────────────────────────────────────────────────────────────────────────┘
```
### Layer 1 — Radio Abstraction Layer
A single function-pointer vtable, `rv_radio_ops_t`, defined in
`firmware/esp32-csi-node/main/rv_radio_ops.h`:
```c
typedef struct {
int (*init)(void);
int (*set_channel)(uint8_t ch, uint8_t bw);
int (*set_mode)(uint8_t mode); /* RV_RADIO_MODE_* */
int (*set_csi_enabled)(bool en);
int (*set_capture_profile)(uint8_t profile_id);
int (*get_health)(rv_radio_health_t *out);
} rv_radio_ops_t;
```
Capture profiles, named not numbered:
| Profile | Intent |
|--------------------------------|-------------------------------------------------------|
| `RV_PROFILE_PASSIVE_LOW_RATE` | Default idle: minimum cadence, presence only |
| `RV_PROFILE_ACTIVE_PROBE` | Inject NDP frames at high rate |
| `RV_PROFILE_RESP_HIGH_SENS` | Quietest channel, longest window, vitals-only |
| `RV_PROFILE_FAST_MOTION` | Short window, high cadence |
| `RV_PROFILE_CALIBRATION` | Synchronized burst across nodes |
Two bindings ship in this ADR:
- **ESP32 binding** (`rv_radio_ops_esp32.c`) wraps `csi_collector.c`,
`esp_wifi_set_channel()`, `esp_wifi_set_csi()`, and
`csi_inject_ndp_frame()`.
- **Mock binding** (`rv_radio_ops_mock.c`) wraps `mock_csi.c` so QEMU
scenarios can exercise the controller and mesh plane without a radio.
A third binding (Nexmon-patched Broadcom) is reserved but not implemented
here.
### Layer 2 — Adaptive controller
`firmware/esp32-csi-node/main/adaptive_controller.{c,h}`. A single FreeRTOS
task with three cooperating timers:
| Loop | Period | Inputs | Outputs |
|--------|---------|------------------------------------------------------------------------|------------------------------------------------------|
| Fast | ~200 ms | packet yield, retry/drop rate, motion score | cadence (vital_interval_ms), active vs passive probe |
| Medium | ~1 s | CSI variance, RSSI median, channel occupancy, inter-node agreement | channel selection (via radio ops), role transitions |
| Slow | ~30 s | drift profile (Stable/Linear/StepChange), respiration confidence | baseline recalibration, switch to delta-only mode |
The controller publishes its decisions through the radio ops vtable
(`set_capture_profile`, `set_channel`) and through the mesh plane
(`CHANNEL_PLAN`, `ROLE_ASSIGN`). Default policy is conservative and matches
today's behavior; aggressive adaptation is opt-in via Kconfig.
### Layer 3 — Mesh sensing plane
Extends `swarm_bridge.c` with explicit node roles (Anchor / Observer /
Fusion relay / Coordinator) and a 7-message type protocol:
| Message | Cadence | Sender(s) | Purpose |
|----------------------|--------------------|------------------|-----------------------------------------------|
| `TIME_SYNC` | 100 ms | Anchor | Reuse ADR-032 `SyncBeacon` (28 bytes, HMAC) |
| `ROLE_ASSIGN` | event-driven | Coordinator | Node ID → role mapping |
| `CHANNEL_PLAN` | event-driven | Coordinator | Per-node channel + dwell schedule |
| `CALIBRATION_START` | event-driven | Coordinator | Synchronized calibration burst |
| `FEATURE_DELTA` | 110 Hz | Observer / Relay | Compact feature delta (see Layer 4) |
| `HEALTH` | 1 Hz | All | `rv_node_status_t` (see below) |
| `ANOMALY_ALERT` | event-driven | Observer | Phase-physics violation, multi-link mismatch |
Node status payload:
```c
typedef struct __attribute__((packed)) {
uint8_t node_id[8];
uint64_t local_time_us;
uint8_t role;
uint8_t current_channel;
uint8_t current_bw;
int8_t noise_floor_dbm;
uint16_t pkt_yield;
uint16_t sync_error_us;
uint16_t health_flags;
} rv_node_status_t;
```
Time-sync target is an engineering goal, not a guaranteed constant — it
depends on the clock quality of the chosen radio family. The first
acceptance test (Phase 2) measures it on real hardware.
### Layer 4 — On-device feature extraction
Defined in `firmware/esp32-csi-node/main/rv_feature_state.h`. Single
on-the-wire packet, **60 bytes packed** (verified by `_Static_assert` and
host unit test), magic `0xC5110006` (next free after ADR-039's
`0xC5110002`, ADR-069's `0xC5110003`, ADR-063's `0xC5110004`, and ADR-039's
compressed `0xC5110005`):
```c
#define RV_FEATURE_STATE_MAGIC 0xC5110006u
typedef struct __attribute__((packed)) {
uint32_t magic; /* RV_FEATURE_STATE_MAGIC */
uint8_t node_id;
uint8_t mode; /* RV_PROFILE_* identifier */
uint16_t seq; /* monotonic per-node sequence */
uint64_t ts_us; /* node-local microseconds */
float motion_score;
float presence_score;
float respiration_bpm;
float respiration_conf;
float heartbeat_bpm;
float heartbeat_conf;
float anomaly_score;
float env_shift_score;
float node_coherence;
uint16_t quality_flags;
uint16_t reserved;
uint32_t crc32; /* IEEE polynomial over bytes [0..end-4] */
} rv_feature_state_t;
_Static_assert(sizeof(rv_feature_state_t) == 60,
"rv_feature_state_t must be 60 bytes on the wire");
```
Three windows feed it: 100 ms (motion), 1 s (respiration), 5 s (baseline /
env shift). Each `rv_feature_state_t` represents the most recent state of
all three; mode field tells the receiver which window dominates this
update.
`rv_feature_state_t` does not replace ADR-039's `edge_vitals_pkt_t`
(0xC5110002) or ADR-063's `edge_fused_vitals_pkt_t` (0xC5110004). Those
remain the wire format for vitals-specific consumers. `rv_feature_state_t`
is the **default upstream payload** for the sensing pipeline; vitals
packets are now an alternate emission mode for backward compatibility.
### Layer 5 — Rust handoff
The Rust side sees only two streams from a node:
1. **`feature_state` stream** — `rv_feature_state_t`, default-on, 110 Hz.
2. **`debug_csi_frame` stream** — ADR-018 raw frames (magic 0xC5110001),
default-off, opt-in via NVS or `CHANNEL_PLAN`. Used for calibration,
debugging, training-set capture.
The Rust handoff is mirrored as a trait in
`crates/wifi-densepose-hardware/src/radio_ops.rs` so test harnesses (and
eventually the Rust-side controller for centralized coordinator nodes) can
swap radio backends without touching `wifi-densepose-signal`,
`wifi-densepose-ruvector`, `wifi-densepose-train`, or
`wifi-densepose-mat`. Rust-side mirror trait is **out of scope for the
firmware-only PR** that ships this ADR; tracked as Phase 4 follow-up.
## State Machine
```
BOOT → SELF_TEST → RADIO_INIT → TIME_SYNC → CALIBRATION → SENSE_IDLE
↓ ↑
SENSE_ACTIVE
ALERT
DEGRADED
```
Transitions:
- **CALIBRATION** on boot, on role change, on sustained inter-node
disagreement.
- **SENSE_ACTIVE** when motion or anomaly score crosses threshold.
- **DEGRADED** when packet yield, sync quality, or memory pressure drops
below threshold; falls back to ADR-039 Tier-0 raw passthrough as the
last-resort survivable mode.
## Data budgets
| Stream | Default rate | Notes |
|-------------------------|-----------------------------|----------------------------------------------|
| Raw capture (internal) | 50200 pps per observer | Stays on-device unless debug stream enabled |
| `rv_feature_state_t` | 110 Hz per node | Default upstream |
| `ANOMALY_ALERT` | event-driven | Burst-bounded |
| Debug ADR-018 raw CSI | 0 (off by default) | Burst-only via `CHANNEL_PLAN` debug flag |
ADR-039 measured raw CSI at ~5 KB/frame and ~100 KB/s per node. The default
upstream with ADR-081's 60-byte `rv_feature_state_t` at 5 Hz is **300 B/s
per node — a 99.7% reduction**. A 50-node deployment at 5 Hz fits in
15 KB/s total, easily carried by a single-AP backhaul.
## Channel planning policy
Codified rules — these are constraints on the controller, not just defaults:
- Keep one anchor on a stable channel; observers distributed across the
least-congested channels.
- Rotate **one** observer at a time. Never change all nodes simultaneously.
- Pin `RV_PROFILE_RESP_HIGH_SENS` to the quietest stable channel for the
duration of a respiration window.
- Use a short active burst on a quiet channel for calibration, then return
to passive capture.
This generalizes the per-deployment policy in ADR-073 ("node 1: ch 1/6/11,
node 2: ch 3/5/9") into a controller-driven plan that the coordinator can
publish via `CHANNEL_PLAN`. IEEE 802.11bf is the standards direction this
points toward.
## Security & integrity
- Every `FEATURE_DELTA` carries node id, monotonic seq, ts_us, and CRC32
(IEEE polynomial), per the struct above.
- Every control message (`ROLE_ASSIGN`, `CHANNEL_PLAN`, `CALIBRATION_START`)
carries sender role, epoch, replay window index, and authorization class,
reusing the HMAC-SHA256 + 16-frame replay window from ADR-032
(`secure_tdm.rs`).
- Optional Ed25519 signature at session/batch granularity for signed
`CHANNEL_PLAN` and `CALIBRATION_START` messages, reusing the
ADR-040/RVF Ed25519 path already shipping in firmware.
## Reuse map (do not rewrite)

## Measured performance
Host-side benchmarks (`firmware/esp32-csi-node/tests/host/`), x86-64,
gcc `-O2`, 2026-04-19. Numbers are illustrative of algorithmic cost on
a modern CPU; on-target ESP32-S3 Xtensa LX7 at 240 MHz is ~510×
slower for bit-by-bit CRC and broadly comparable for the decide
function after inlining.
| Operation | Cost per call | Notes |
|---------------------------------------------|---------------------|-------------------------------------|
| `adaptive_controller_decide()` | **3.2 ns** (host) | O(1) policy, 9 branches evaluated |
| `rv_feature_state_crc32()` (56 B hashed) | **612 ns** (host) | 87 MB/s — bit-by-bit IEEE CRC32 |
| `rv_feature_state_finalize()` (full) | **592 ns** (host) | CRC-dominated |
| `rv_mesh_encode_health()` + `_decode()` | **1010 ns** (host) | Full roundtrip, hdr+payload+CRC |
Projected on-target cost at 5 Hz cadence:
| Budget | Value |
|--------------------------------------------|---------------------|
| Controller fast-loop tick work (ESP32-S3) | < 10 μs (est.) |
| CRC32 per feature packet (ESP32-S3) | ~36 μs (est.) |
| Feature-state emit cost @ 5 Hz | ~30 μs/sec (0.003%) |
| UDP send cost (existing stream_sender) | — unchanged — |
**Bandwidth:**
| Mode | Rate |
|---------------------------------------------|-------------|
| Raw ADR-018 CSI (pre-ADR-081) | ~100 KB/s |
| ADR-039 compressed CSI (Tier 1) | ~5070 KB/s |
| ADR-039 vitals packet (32 B @ 1 Hz) | 32 B/s |
| **ADR-081 feature state (60 B @ 5 Hz)** | **300 B/s** |
**Memory:**
| Component | Static RAM |
|---------------------------------------------|---------------------|
| Controller state (s_cfg + s_last_obs + …) | ~80 bytes |
| Feature-state emit packet (stack, per tick) | 60 bytes |
| CRC lookup table | 0 (bit-by-bit) |
| Three FreeRTOS software timers | ~3 × 56 B overhead |
**Tests:**
| Suite | Assertions | Result |
|---------------------------------------------|-----------:|------------|
| `test_adaptive_controller` (host C) | 18 | **PASS** |
| `test_rv_feature_state` (host C) | 15 | **PASS** |
| `test_rv_mesh` (host C) | 27 | **PASS** |
| `radio_ops::tests` (Rust) | 8 | **PASS** |
| **Total** | **68** | **68/68** |
| QEMU validator (`ADR-061` pipeline) | +3 checks | hooked |
Cross-language parity: the Rust `crc32_ieee()` is verified against the
same known vectors used by the C test (`0xCBF43926` for `"123456789"`,
`0xD202EF8D` for a single zero byte), and the `mesh_constants_match_firmware`
test asserts `MESH_MAGIC`, `MESH_VERSION`, `MESH_HEADER_SIZE`, and
`MESH_MAX_PAYLOAD` match the C header byte-for-byte. Any drift between
the two implementations fails CI.
## New components this ADR authorizes
| New file | Purpose |

## Roadmap
| Phase | Scope | Status |
|-------|--------------------------------------------|--------------------------------------------------|
| 1 | Single supported-CSI node + features → Rust | Largely done via ADR-018, ADR-039 |
| 2 | 3-node Seed v2 mesh + time-sync + plan | Partially done (ADR-029, ADR-066, ADR-073) |
| 3 | Adaptive controller, delta reporting, DEGRADED | **This ADR** authorizes the firmware skeleton |
| 4 | Cross-chipset bindings (Nexmon, custom) | Reserved; gated by Phase 3 stability |
## Acceptance criteria
1. **Portability gate.** A second `rv_radio_ops_t` binding (mock or
alternate chipset) compiles and runs the controller + mesh plane code
unchanged. The signal/ruvector/train/mat crates compile against a Rust
mirror trait without modification.
2. **Mesh resilience benchmark.** A 3-node prototype maintains stable
`presence_score` and `motion_score` when one observer changes channel
or drops out for 5 seconds.
3. **Default upstream is compact.** Raw ADR-018 CSI is off by default; the
default upstream is `rv_feature_state_t` at 110 Hz.
4. **Integrity.** Every `FEATURE_DELTA` carries node id, seq, ts_us, CRC32.
Every control message carries epoch + replay-window + authorization
class, verified against ADR-032's existing HMAC machinery.
## Consequences
### Positive
- The firmware hack is no longer the moat. The 5 layers are explicit and
separately testable.
- Default upstream bandwidth drops ~99% vs. raw ADR-018, making 50+ node
deployments practical.
- A documented vtable + Kconfig surface gates new features ("which layer
does this belong in?") instead of letting them accrete inline.
- Adaptive control of cadence, channel, and role becomes a first-class
firmware concern — the user-facing knob ("be smarter when busy, save
power when idle") finally has a home.
### Negative
- An abstraction tax on the single-chipset case: `rv_radio_ops_t` is a
vtable for a family currently of size 1.
- Adds ~58 KB SRAM for controller state and the new feature-state ring.
- Requires re-routing existing `swarm_bridge` traffic through the mesh
plane message types over time (incremental, not breaking).
### Neutral
- This ADR introduces no new dependencies, no new networking stacks, and
no new hardware requirements.
- ADR-039, ADR-063, ADR-066, ADR-069, ADR-073 are **not superseded**; they
are reframed as components of Layer 3 / Layer 4.
## Verification
```bash
# Host-side C unit tests (no ESP-IDF, no QEMU required)
cd firmware/esp32-csi-node/tests/host
make check
# → test_adaptive_controller: 18/18 pass, decide() = 3.2 ns/call
# → test_rv_feature_state: 15/15 pass, CRC32(56 B) = 612 ns/pkt
# → test_rv_mesh: 27/27 pass, HEALTH roundtrip = 1.0 µs
# Rust-side radio_ops trait + mesh decoder tests
cd v2
cargo test -p wifi-densepose-hardware --no-default-features --lib radio_ops
# → 8 passed; verifies MockRadio, CRC32 parity with firmware vectors,
# HEALTH encode/decode roundtrip, bad-magic/short/CRC rejection,
# and that MESH_MAGIC/VERSION/HEADER_SIZE match rv_mesh.h
# QEMU end-to-end (requires ESP-IDF + qemu-system-xtensa, see ADR-061)
bash scripts/qemu-esp32s3-test.sh

# ADR-082: Pose Tracker Confirmed-Track Output Filter
| Field | Value |
|-------------|-----------------------------------------------------------------------|
| **Status** | Accepted — implemented in commit landing this ADR |
| **Date** | 2026-04-25 |
| **Authors** | ruv |
| **Issue** | [#420 — "24 ghost people in the UI with 3× ESP32-S3 nodes"](https://github.com/ruvnet/RuView/issues/420) |
| **Depends** | ADR-026 (track lifecycle), ADR-024 (AETHER re-ID embeddings) |
## Context
Multiple users running the Rust sensing server with 3 ESP32-S3 nodes have
reported the same symptom: the live UI renders 2224 phantom skeletons that
flicker at high rate, while `GET /api/v1/sensing/latest` correctly reports
`estimated_persons: 1`. The problem is reproducible across both Docker and
native deployments and is independent of the firmware MGMT-only mitigation
shipped for #396.
The two-number contradiction (1 in the snapshot, ~24 in the WebSocket stream)
narrows the bug to the path that produces `update.persons`. That path is
`tracker_bridge::tracker_update``tracker_bridge::tracker_to_person_detections`
→ WebSocket frame.
### Pose tracker lifecycle (per ADR-026)
`signal::ruvsense::pose_tracker::TrackLifecycleState` has four states:
```
Tentative -> Active -> Lost -> Terminated
```
The state machine and its predicates:
| State | `is_alive()` | `accepts_updates()` | Meaning |
|--------------|--------------|---------------------|---------|
| `Tentative` | true | true | New detection, < 2 confirmed hits |
| `Active` | true | true | Confirmed track, currently observed |
| `Lost` | **true** | false | Confirmed track, missed `loss_misses` updates, still inside `reid_window` |
| `Terminated` | false | false | Removed on next `prune_terminated()` |
`PoseTracker::active_tracks()` filters by `is_alive()`, which means it returns
`Tentative Active Lost` — every track that has not yet been Terminated.
### Root cause
`crates/wifi-densepose-sensing-server/src/tracker_bridge.rs` exposes the
tracker output to the WebSocket stream via:
```rust
/// Convert active PoseTracker tracks back into server-side PersonDetection values.
///
/// Only tracks whose lifecycle `is_alive()` are included.
pub fn tracker_to_person_detections(tracker: &PoseTracker) -> Vec<PersonDetection> {
tracker
.active_tracks()
.into_iter()
.map(|track| { /* ... */ })
.collect()
}
```
The doc comment is correct as a description of `is_alive()`, but `is_alive()`
is the wrong gate for *rendering*. `Lost` tracks have not received a
measurement in `loss_misses` ticks; they are kept around only so the
re-identification machinery can attempt to match them when a similar
detection reappears within `reid_window`. They are not currently observed and
must not appear as live skeletons in the UI.
With 3 ESP32-S3 nodes streaming CSI at ~10 Hz each, `derive_pose_from_sensing`
emits a per-node detection every tick. Detections that fall outside the
Mahalanobis gate (cost ≥ 9.0) cannot match an existing track, so a new
`Tentative` track is created and the previous one ages into `Lost`. With
`reid_window ≈ 30` ticks (~3 s at 10 Hz), up to 30 ticks × 3 nodes ≈ 90
phantom Lost tracks can co-exist before any of them reach `Terminated`.
The actually-observed-now person is one of them; the other ~2289 are ghosts.
The snapshot endpoint `/api/v1/sensing/latest` reads `estimated_persons` from
the multistatic eigenvalue counter (`signal::ruvsense::field_model`), which
operates on the CSI data directly and reports 1. The WebSocket stream reads
`update.persons`, which is the unfiltered `is_alive()` set — hence the
22-vs-1 mismatch.
This is a documentation/implementation discrepancy in `tracker_bridge`, not a
flaw in the lifecycle state machine itself.
## Decision
Introduce a **confirmed-track filter** at the bridge boundary that returns
only tracks the UI is meant to render:
* `Active` — confirmed and currently observed; always render.
* `Tentative` — confirmed for the *current* tick (created or matched this
cycle); render so first-frame visibility latency stays at one tick.
* `Lost`**never** render. They exist only to support re-ID over the
`reid_window` and have, by definition, not been observed for at least
`loss_misses` ticks.
* `Terminated` — never render (already excluded by `is_alive()`).
### Naming
Add `PoseTracker::confirmed_tracks()` — the name reflects "tracks the system
is currently confirming a person is present at this position." Keep
`active_tracks()` unchanged so callers that legitimately need the re-ID set
(re-identification, soft-confidence overlays, debug UIs) still have it.
The bridges public surface stays the same; only the internal accessor
swaps. WebSocket consumers see the corrected `update.persons` automatically.
### Why include `Tentative`
A walking persons first detection lands in `Tentative` until two consecutive
hits arrive (~0.1 s at 10 Hz). Excluding `Tentative` makes the UI
under-render by one tick on every entry; the gain (filtering out spurious
single-detection ghosts) is real but small relative to the much larger Lost
problem and isnt worth the visible latency. If single-tick ghosts become
the dominant complaint after this ADR ships, escalate to `Active`-only and
revisit `birth_hits` calibration.
## Consequences
### Positive
* `update.persons.length` matches `estimated_persons` within ±1 (Tentative
vs. Active hand-off frame) under steady state. #420 closed.
* No change to the lifecycle state machine, no change to `reid_window` or
`loss_misses`, no change to the WebSocket schema. Pure filter at egress.
* `PoseTracker::active_tracks()` keeps its semantics for re-ID consumers;
this avoids breaking ADR-024 (AETHER) call sites.
### Negative / risks
* Existing test `test_tracker_update_stable_ids` exercises three sequential
identical-person updates and asserts the ID is stable across all three.
Filtering Lost out doesnt affect it (the track stays in `Tentative`
`Active`, never Lost during the test). Confirmed by reading the test;
no regression expected.
* Single-tick `Tentative` exposure means very-spurious one-frame detections
*can* still flicker briefly. Acceptable trade-off as discussed above.
### Neutral
* `prune_terminated()` and the existing transition logic
(`predict_all``mark_lost``terminate`) are unchanged.
## Implementation
1. **`signal::ruvsense::pose_tracker`** — add:
```rust
/// Tracks the UI is meant to render: Tentative + Active.
/// Excludes Lost (re-ID candidates) and Terminated.
pub fn confirmed_tracks(&self) -> Vec<&PoseTrack> {
self.tracks
.iter()
.filter(|t| matches!(
t.lifecycle,
TrackLifecycleState::Tentative | TrackLifecycleState::Active
))
.collect()
}
```
2. **`sensing-server::tracker_bridge`** — change
`tracker_to_person_detections` to call `tracker.confirmed_tracks()` and
update the doc comment to describe the new contract.
3. **Regression test** in `tracker_bridge.rs::tests`:
* Drive a track to `Active` over two updates.
* Submit empty detections for `loss_misses + 1` predict cycles to push
the track to `Lost`.
* Assert `tracker_update(... empty ...)` returns an empty `Vec`.
4. **Validation**: workspace tests + ESP32-S3 on COM7 streaming round-trip.
## Validation
* `cargo test --workspace --no-default-features` — must stay green
(≥ 1,538 passed, 0 failed; new regression test adds one).
* Live verification on ESP32 setup: WebSocket `update.persons.length`
must equal `estimated_persons` ± 1 in steady state.

# ADR-083: Per-Cluster Pi Compute Hop
| Field | Value |
|----------------|--------------------------------------------------------------------------------------|
| **Status** | Proposed — pending field evidence on three-tier proposal scope |
| **Date** | 2026-04-26 |
| **Authors** | ruv |
| **Supersedes** | — |
| **Refines** | ADR-028 (capability audit), ADR-081 (5-layer kernel), ADR-066 (swarm bridge) |
| **Companion** | `docs/research/architecture/three-tier-rust-node.md`, `docs/research/architecture/decision-tree.md`, `docs/research/sota/2026-Q2-rf-sensing-and-edge-rust.md` |
## Context
ADR-028 established the per-node BOM at ~$9 (ESP32-S3 8MB) — ~$15 with a
mmWave sensor — and ADR-081 framed the firmware as a 5-layer adaptive
kernel running entirely on a single ESP32-S3 die. Both decisions are
correct for the **per-node** dimension; deployments that fit the
"sensor talks UDP to a server somewhere" shape work fine on this stack.
The three-tier-node research exploration
(`docs/research/architecture/three-tier-rust-node.md`) raised a separate
question: **what changes when a deployment scales past one or two rooms,
and where should the heavy compute live?** The exploration's answer
("dual ESP32-S3 + Pi Zero 2W per node") is one shape, but the
companion decision-tree (`decision-tree.md` §1, §3 L3, §5) identifies a
materially cheaper path: keep today's single-S3 sensor node unchanged
and add **one Pi per cluster of 36 sensor nodes**. The 2026-Q2 SOTA
survey (`sota/2026-Q2-rf-sensing-and-edge-rust.md`) confirms that the
load this path needs to carry — model inference, QUIC backhaul, and a
real secure-boot story — fits comfortably on a Pi-class SoC, while the
load it doesn't need to carry — CSI capture, ISR-precise wake control —
is exactly what the ESP32-S3 already does well.
The three things this ADR is about, all of which the current single-S3
deployment shape pushes onto the cloud or onto every individual node:
1. **Per-deployment ML inference.** WiFlow / DT-Pose / GraphPose-Fi
class models (410M params, 0.51.5 GFLOPs) want a Cortex-A53-class
target. The ESP32-S3 cannot host these; the cloud can but only at
the cost of round-trip latency. A per-cluster Pi inference hop is
the natural home.
2. **QUIC backhaul.** `quinn` + `rustls` is mature on Linux but does
not run on ESP32-class hardware in any production-grade form
(SOTA §5). A Pi terminating QUIC for a cluster gives every sensor
node QUIC's loss/handoff/multiplex properties without porting QUIC
to the MCU.
3. **Secure-boot anchor for OTA.** ESP-IDF Secure Boot V2 covers each
sensor node, but cluster-wide policy (which model is current, which
sensor MCU image is canary, what is the rollout ring) needs a
higher-trust local store. A Pi running buildroot + dm-verity +
signed FIT is a defensible anchor without the BOM hit of CM4 / Pi 5
(the latter is its own decision; see ADR-085 sketch below and
decision-tree.md L6).
The cluster-Pi shape does **not** require any change to ADR-028 or
ADR-081. The sensor node continues to be a single-MCU ESP32-S3 running
the 5-layer kernel. Everything new lives at the cluster boundary.
## Decision
Adopt **a per-cluster Pi hop** as the canonical RuView mid-scale
deployment shape. A "cluster" is **36 ESP32-S3 sensor nodes within
WiFi mesh range of one Pi**.
Specifically:
1. **Sensor nodes are unchanged.** They continue to run the ADR-081
5-layer kernel on a single ESP32-S3, emit `rv_feature_state_t`
packets (60 byte, ~5 Hz, ~300 B/s) over UDP, and connect via
ESP-WIFI-MESH or direct WiFi to the cluster Pi.
2. **Each cluster has exactly one Pi** acting as:
- **Sensor aggregator**: ingests UDP from all cluster sensor
nodes, runs feature-level fusion (multistatic + viewpoint
attention from the existing `wifi-densepose-ruvector` crate).
- **ML inference target**: hosts the WiFi-pose model and runs
inference at the cluster boundary, not on each sensor MCU.
- **QUIC client to the cloud / gateway**: terminates QUIC mTLS,
batches cluster-level events.
- **OTA + secure-boot anchor for its sensor nodes**: holds signed
manifests, stages canary rollouts, owns provisioning state.
3. **Cluster Pi SoC choice is deferred** to a future ADR (sketched
below as ADR-085). The acceptable candidates are Pi Zero 2W, Pi 4,
Pi 5, and CM4. The decision tree's L6 distinguishes these by
secure-boot threat model; this ADR does not pre-commit.
4. **The single-node deployment shape is not deprecated.** A
home-lab / single-room / development deployment can still run a
single ESP32-S3 talking UDP directly to the existing
`wifi-densepose-sensing-server`, no Pi required. The cluster Pi
becomes the recommended shape for fleets ≥ 3 sensor nodes.
### Boundary contract
The cluster Pi exposes two interfaces:
| Interface | Direction | Schema |
|------------------------|-------------------|-----------------------------------------------------------------------|
| **UDP `rv_feature_state_t` ingest** | sensor → Pi | Existing 60-byte packed struct from ADR-081 (magic `0xC5110006`) |
| **QUIC mTLS uplink** | Pi → gateway/cloud | New: cluster-level event envelope (CBOR), batched, ~10 KB/min upper bound |
Sensor → Pi is **the same wire as today's sensor → server**. Cluster Pi
uplink is **new** and is what the existing `wifi-densepose-sensing-server`
becomes — relocated from the user's laptop / container to the cluster
node. Concretely: the sensing server already exists in
`crates/wifi-densepose-sensing-server`; it cross-compiles to ARMv7 /
AArch64 today via `cargo build --target aarch64-unknown-linux-gnu`. The
relocation is a deployment change, not a re-implementation.
### Three-tier vs cluster hop
This ADR's cluster-Pi shape is the L3-hybrid path in
`decision-tree.md` §2 — **not** the full three-tier (dual-MCU + per-node
Pi) shape. It captures most of the value (ML, QUIC, secure-boot anchor)
at minimal BOM impact. The full three-tier shape remains the long-term
exploration target, blocked behind L4 (no_std CSI maturity) and L2
(per-node ISR-jitter evidence).
## Consequences
### Positive
- **Pose-grade ML on edge becomes deployable**, not just possible. A
Pi (any of the eligible SoCs) hosts WiFlow-class models with
≤ 100 ms latency per cluster, vs ≥ 1 s round-trip if pose runs in the
cloud (SOTA §1, §3).
- **QUIC arrives without an MCU port.** `quinn` + `rustls` runs on the
Pi as it does on a server (SOTA §5). The sensor MCU keeps UDP — the
cheapest, highest-tested wire it already speaks.
- **Cluster-level secure boot becomes coherent.** Per-sensor Secure
Boot V2 + flash encryption (ADR-028 baseline) is unchanged. The Pi
buildroot + dm-verity image is the cluster trust anchor and signs
the OTA manifests for its sensors. The cluster-level threat model is
expressible without per-sensor BOM regression.
- **No PCB respin.** Sensor nodes are bit-for-bit identical to today's
ADR-028 baseline. The cluster Pi is a separate device on the cluster
WiFi (and / or Ethernet, if available).
- **Deployment cost scales sub-linearly with sensor count.** One
$25$60 Pi per 36 sensor nodes adds ~$5$20 per sensor amortized,
vs ~$25$50 per sensor for the per-node-Pi shape.
### Negative
- **The cluster Pi is a new piece of infrastructure to provision,
monitor, and update.** It is the right place for cluster-level
responsibilities, but it is not free; it adds a Linux box to every
multi-room deployment. Mitigated by buildroot images and the
existing OTA tooling story (see Implementation §4).
- **Cluster Pi failure takes the cluster offline** (sensor nodes
cannot uplink without a working aggregator on the WiFi LAN). For
high-availability deployments, this ADR is the floor; an HA-pair
cluster Pi would be a follow-up.
- **One more network hop on the sensing path.** Sensor → Pi → cloud
adds ~520 ms over Sensor → cloud (depending on link quality).
Pose latency budgets are 100s of ms, so this is well inside spec.
### Neutral
- ADR-028 (capability audit), ADR-081 (5-layer kernel), and ADR-066
(swarm bridge) are unchanged. This ADR adds a new device class above
the sensor; it does not modify the sensor itself.
- The home-lab single-node shape continues to work; this ADR adds a
recommended path for fleets, it does not deprecate the existing one.
## Implementation
The implementation is intentionally light because most of the pieces
already exist; the ADR is largely about formalizing where they live.
1. **Cluster-Pi cross-compile target.** Add to
`rust-port/wifi-densepose-rs/.cargo/config.toml` (or the equivalent
per-crate target spec) an `aarch64-unknown-linux-gnu` target so
`wifi-densepose-sensing-server` builds for Pi 4 / 5 / CM4 by
default. Also retain `armv7-unknown-linux-gnueabihf` for Pi Zero 2W
compatibility while the Pi-SoC decision (ADR-085 sketch) is open.
2. **Cluster-Pi service unit.** Add a systemd unit file under
`firmware/cluster-pi/` (new directory) that runs
`wifi-densepose-sensing-server` with the cluster's UDP/QUIC ports
and drops privileges. Buildroot integration is a separate ADR if
the SoC choice goes to Pi Zero 2W (where there's no RPi-OS path).
3. **QUIC uplink module.** Add `wifi-densepose-sensing-server` a
feature-gated `quic-uplink` module using `quinn` + `rustls`. The
feature is **off by default** in the home-lab shape and on for the
cluster Pi.
4. **OTA + signed-manifest flow.** Out of scope for this ADR; tracked
as I4 in `decision-tree.md` §4. The cluster Pi's role is to *hold*
the manifest store, not to define the manifest format. Use the
existing ADR-066 swarm bridge channel for OTA staging.
5. **Documentation update.** README's hardware-table gains a
"Cluster compute" row. CLAUDE.md gets a one-paragraph cluster-Pi
section under Architecture. User-guide gets a cluster-deployment
section.
6. **Validation.** A 3-sensor cluster + 1 Pi fixture in the lab.
Pass criteria: end-to-end CSI → cluster fusion → cloud ingest;
measured latency under 100 ms per cluster; cluster Pi reboot
without sensor data loss > 5 s; OTA staging round-trip across all
sensors in the cluster.
## Validation
This ADR is **proposed**, not accepted. Acceptance requires:
1. The cluster-Pi `wifi-densepose-sensing-server` cross-compiles
cleanly on `aarch64-unknown-linux-gnu` and `armv7-unknown-linux-gnueabihf`
targets with the existing workspace tests passing.
2. A 3-sensor + 1-Pi field test demonstrates ≥ 4 hours stable
end-to-end CSI → fusion → cloud round-trip with latency
≤ 100 ms per cluster and zero phantom-skeleton regressions
(ADR-082 holds across the new uplink).
3. The cluster-Pi ↔ sensor secure-boot story is approved alongside
ADR-085's SoC choice.
When the above pass, this ADR moves from **Proposed** → **Accepted**
and the README + CLAUDE.md are updated to reflect cluster-Pi as the
recommended fleet-shape.
## Related ADRs (current and proposed)
- **ADR-028** (Accepted) — ESP32 capability audit. Single-node BOM
baseline. Unchanged by this ADR.
- **ADR-029** (Proposed) — RuvSense multistatic sensing mode. Pairs
naturally with cluster-Pi: cluster Pi is the natural home for
multi-sensor fusion.
- **ADR-066** — Swarm bridge to coordinator. The cluster-Pi is the
per-cluster swarm coordinator endpoint.
- **ADR-081** (Accepted) — 5-layer adaptive CSI mesh firmware kernel.
Unchanged by this ADR.
- **ADR-082** (Accepted) — Pose tracker confirmed-track output filter.
Holds across UDP and QUIC uplinks identically.
- **Future ADR (sketched in `decision-tree.md` L4)**`no_std` CSI
capture maturity benchmark. Gates the dual-MCU shape; not required
for the cluster-Pi shape proposed here.
- **Future ADR (sketched in `decision-tree.md` L6)** — Cluster-Pi SoC
choice (Pi Zero 2W vs CM4 vs Pi 5). Pure secure-boot decision.
## Open questions
- **Cluster size sweet spot.** "36 nodes" is a planning estimate. The
3-sensor lab fixture in §Implementation will inform whether the
upper bound is closer to 4, 6, or 8 in practice.
- **Cluster-Pi failure semantics.** Default behavior: sensor MCUs hold
the last 60 s of feature packets in RAM and replay on reconnect.
HA-pair cluster Pi is a separate ADR if needed.
- **Mesh control-plane interaction.** If the deployment moves to
Thread (decision-tree.md L5), the cluster Pi may need a Thread
Border Router role. This ADR doesn't pre-commit; it's compatible
with both ESP-WIFI-MESH and Thread futures.

# ADR-084: RaBitQ Similarity Sensor for CSI / Pose / Memory Routing
| Field | Value |
|----------------|-----------------------------------------------------------------------------------------|
| **Status** | Proposed |
| **Date** | 2026-04-26 |
| **Authors** | ruv |
| **Refines** | ADR-024 (AETHER re-ID embeddings), ADR-027 (cross-environment domain generalization), ADR-076 (CSI spectrogram embeddings), ADR-081 (5-layer firmware kernel) |
| **Companion** | ADR-083 (per-cluster Pi compute hop) |
| **Implements** | `vendor/ruvector/crates/ruvector-core/src/quantization.rs::BinaryQuantized` |
## Context
RuView's signal pipeline already produces several **dense float
embeddings** at different layers:
- AETHER 128-d re-ID embeddings on each `PoseTrack` (ADR-024)
- 64256-d CSI spectrogram embeddings (ADR-076)
- per-room field-model eigenmode vectors (ADR-030)
- per-frame multistatic fused vectors (ADR-029)
Every one of these eventually answers the same shape of question:
**"have I seen something like this before?"** Today the answer is
computed by full float dot-product / Mahalanobis comparisons against a
candidate set. That cost grows linearly with stored vectors and
quadratically when used inside dynamic-mincut graph maintenance,
re-identification re-scoring, and cross-environment domain detection.
The vendored `ruvector-core` crate already ships a 1-bit quantization
(`BinaryQuantized`, 32× compression, SIMD popcnt + hamming distance)
that is functionally equivalent to the **RaBitQ** family of binary
sketches: a vector is reduced to one bit per dimension, compared via
hamming distance, and used as a coarse pre-filter before full
precision refinement. The same module also exposes `ScalarQuantized`
(int8, 4×) and `ProductQuantized` (PQ, 816×), so the tiered
quantization story is already implemented; the *deployment pattern* is
not.
The user observation that motivates this ADR: **RaBitQ-style sketches
are not just a vector compression trick — they are a cheap similarity
sensor.** Used as a sensor, they unlock:
- always-on novelty / anomaly gating that wakes heavy CNNs only on
meaningful change
- cluster-Pi memory routing (which shard / room / model to query first)
- cross-node mesh exchange of compressed sketches instead of raw vectors
- privacy-preserving event logs (sketches, not reconstructable signals)
This ADR formalizes the deployment pattern across the RuView stack and
commits to `ruvector::quantization::BinaryQuantized` as the canonical
implementation.
## Decision
Adopt **RaBitQ-style binary sketches as a first-class, cheap
similarity sensor** at four points in the RuView pipeline:
1. **CSI / pose embedding hot-cache filter** at the cluster Pi.
2. **Drift / novelty sensor** between live observation and a
per-room normal-state bank.
3. **Mesh-exchange compression** between sensor nodes when reporting
cross-cluster events.
4. **Privacy-preserving event log** at the cluster Pi and gateway.
The canonical pattern at every point is:
```text
dense embedding ──► RaBitQ sketch ──► hamming/popcnt compare
├──► candidate set (top-K)
└──► novelty score (0..1)
┌── below threshold ──► emit summary, no escalation
└── above threshold ──► full-precision refinement
├──► ruvector mincut / HNSW
├──► AETHER re-ID rescoring
└──► pose model / CNN wake
```
### Implementation home
- **Sketch type and SIMD primitives**:
`vendor/ruvector/crates/ruvector-core/src/quantization.rs::BinaryQuantized`
— already implemented, already SIMD-accelerated (NEON on aarch64,
POPCNT on x86_64). Re-export through a new
`crates/wifi-densepose-ruvector/src/sketch.rs` module so consumers in
`signal`, `train`, `mat`, and `sensing-server` see a stable
RuView-flavored API and don't bind directly to the vendor crate.
- **Per-room normal-state bank**: lives at the cluster Pi (ADR-083),
not on the sensor MCU. Sensor MCUs continue to emit dense embeddings
in the existing `rv_feature_state_t` packet shape; sketching happens
on the Pi where the candidate bank is.
- **Sketch versioning**: each sketch carries a 16-bit `sketch_version`
field so the Pi can tell incompatible sketches apart when an
embedding model upgrades. Bumped on every embedding-model change.
### Where the sensor sits in the pipeline
| Pipeline stage | Today (full float) | With RaBitQ similarity sensor |
|---|---|---|
| AETHER re-ID match | full 128-d cosine on every active track × candidate | hamming pre-filter to top-K, then full cosine on K |
| Mincut subcarrier selection | full graph re-evaluation | sketch-flagged "likely-changed" boundary edges, full mincut on those |
| CSI room fingerprint | trained classifier on full embedding | sketch hamming to per-room sketch, classifier on miss |
| Field-model novelty (ADR-030) | residual-energy threshold | sketch novelty as second gate before SVD redo |
| Mesh / inter-cluster sync | dense embedding broadcast | sketch broadcast; full vector only on miss |
| Event log retention | full embedding stored | sketch + witness hash stored; raw embedding ephemeral |
In every row, the **decision boundary is unchanged** — full precision
still owns the final answer. The sketch is a sensor that only gates
which comparisons run, not what they decide.
### Acceptance criterion (per the source proposal)
The system-level acceptance test is:
> RaBitQ should reduce compare cost by **8× to 30×** while preserving
> top-k decisions well enough that full refinement changes **fewer
> than 10%** of final results.
Concretely, this means:
- Sketch compare must be measurably **8× cheaper** than the float
comparison it replaces (criterion-bench in `signal/`).
- Top-K candidate set chosen by sketch must contain ≥ 90% of the
candidates the full-float pass would have picked (offline replay
against recorded CSI).
- End-to-end pose / re-ID accuracy must regress by **less than 1
percentage point** vs the full-float baseline on the existing
evaluation set.
If any of these three fail, the sensor is rolled back at that point in
the pipeline and the failing site reverts to full float; the rest of
the pipeline keeps using sketches. This is point-by-point, not
all-or-nothing.
## Consequences
### Positive
- **Cheaper hot path everywhere a "have I seen this" question lives.**
AETHER re-ID, mincut maintenance, room fingerprinting, novelty
detection, mesh sync, and event-log retention all run a 32×-smaller,
popcnt-friendly comparison first.
- **Always-on anomaly gating becomes affordable.** The CNN / pose
model only wakes when sketch novelty crosses a threshold. Energy
budget per node drops materially in steady-state quiet rooms.
- **Privacy story improves.** Event logs and inter-cluster mesh
traffic carry sketches and witness hashes, not reconstructable
embeddings. The 1-bit quantization is *not* invertible to the
original CSI.
- **Composes cleanly with ADR-083.** The cluster Pi is the natural
home for the sketch bank; sensor MCUs remain unchanged.
- **No new dependency.** `BinaryQuantized` is already in the vendored
`ruvector-core` and already SIMD-accelerated.
### Negative / risks
- **Sketch quality depends on embedding distribution.** Pure 1-bit
sign quantization (which `BinaryQuantized` implements) works best
when the embedding space is roughly zero-centered and isotropic.
AETHER and CSI spectrogram embeddings need to be benchmarked for
this assumption; if either fails, a randomized rotation
(Johnson-Lindenstrauss / RaBitQ-paper-style) must be added before
sketching. Out-of-scope for this ADR; tracked as a follow-up if
the acceptance test fails.
- **Top-K coverage degrades for small candidate sets.** With < 16
candidates, the sketch compare can pick the wrong K. Site-by-site
fallback to full float is part of the rollout plan.
- **Sketch-version skew during model upgrades.** A model change
invalidates all stored sketches; the cluster Pi must re-sketch the
candidate bank when `sketch_version` bumps. Cost is bounded but
non-zero.
### Neutral
- ADR-024, ADR-027, ADR-029, ADR-030, ADR-076 are unchanged in
*what* they compute. They gain a sketch pre-filter at the comparison
step.
- ADR-082's confirmed-track output filter is upstream of the sketch
layer; it stays correct.
## Implementation
The implementation lands in five passes, each independently testable.
Every pass is gated by the acceptance criterion above; if any fail,
that site rolls back and the rest continue.
1. **`wifi-densepose-ruvector::sketch` module.** Re-export
`BinaryQuantized` plus a thin RuView-flavored API
(`Sketch::from_embedding`, `Sketch::distance`, `SketchBank::topk`).
Add `sketch_version: u16` and `embedding_dim: u16` fields to the
public type. Criterion benches: sketch ↔ float compare-cost ratio.
2. **AETHER re-ID pre-filter.** In
`wifi-densepose-signal/src/ruvsense/pose_tracker.rs`, before
computing the full 128-d cosine across active tracks × candidates,
sketch both sides and reduce to top-K via hamming. Bench: re-ID
pass time per frame, ID-stability under cross-room transitions.
3. **Cluster-Pi novelty sensor.** In
`wifi-densepose-sensing-server`, maintain a per-room
`SketchBank` of "normal-state" sketches; on each incoming
`rv_feature_state_t`, compute embedding sketch, score novelty
against the bank, and emit `novelty_score` as a new field on the
WebSocket update envelope. Heavy CNN wake gate uses this score.
4. **Mesh-exchange compression.** Inter-cluster broadcasts (the
ADR-066 swarm-bridge channel) carry sketch + witness instead of
the full embedding when novelty is low. Full embedding only
exchanged when novelty crosses threshold.
5. **Privacy-preserving event log.** Event log table on the cluster
Pi stores `(sketch_bytes, sketch_version, novelty_score,
witness_sha256)` instead of raw embeddings. Existing log readers
are unchanged in API; only the storage layer rewrites.
Each pass adds tests: a property test (sketch ↔ float top-K agreement
≥ 90%), a criterion bench (≥ 8× compare cost reduction), and an
end-to-end accuracy regression test (< 1 pp drop).
## Validation
This ADR is **proposed**, not accepted. Acceptance requires the three
acceptance numbers above to hold on **at least three of the five
implementation passes** (the sites where the bulk of the load sits:
AETHER re-ID, cluster-Pi novelty, and event log). The mesh-exchange
and mincut prefilter passes are nice-to-haves; they can ship
afterward if their per-site numbers hold.
Validation runs against:
- the existing 1,539-test workspace suite (must stay green)
- a new `tests/integration/rabitq_sketch_pipeline.rs` integration test
driving recorded CSI through the full pipeline with and without
sketches, comparing top-K decisions and end-to-end pose accuracy
- ESP32-S3 on COM7 — sensor MCU unchanged; sketch happens at the
cluster Pi, so this validation is a smoke test that the
sensor → Pi UDP path still works after the cluster Pi gains the
sketch bank
## Related
- **ADR-024** (Accepted) — AETHER re-ID embeddings. Primary consumer
of the sketch pre-filter.
- **ADR-027** (Accepted) — Cross-environment domain generalization
(MERIDIAN). Per-room sketch bank is the natural data structure for
domain detection.
- **ADR-030** (Proposed) — RuvSense persistent field model. Sketch
novelty is the cheap second gate before SVD recompute.
- **ADR-066** — Swarm bridge to coordinator. Inter-cluster sketch
exchange.
- **ADR-076** (Accepted) — CSI spectrogram embeddings. Sketch

- **ADR-081** (Accepted) — 5-layer adaptive CSI mesh firmware kernel.
Sensor MCU unchanged by this ADR; sketches happen at the cluster Pi.
- **ADR-083** (Proposed) — Per-cluster Pi compute hop. Defines the
device class that hosts the sketch bank.
## Open questions
- **Does `BinaryQuantized` need a randomized rotation pre-pass for
RuView's embedding distributions?** Pure sign quantization assumes
zero-centered, isotropic embeddings. If AETHER / spectrogram
distributions are skewed (likely for spectrogram), add a
`randomized_rotation` pre-pass following the original RaBitQ paper
(Gao & Long, SIGMOD 2024). Decided after pass-1 benchmark.
- **Sketch dimension target.** Default to the embedding's native
dimension (128 for AETHER, 256 for spectrogram). Higher-dimensional
sketches (Johnson-Lindenstrauss-projected to 512) trade compute for
recall; benchmark before committing.
- **Per-room vs per-deployment sketch banks.** Defaulting to per-room
for novelty detection. Cross-room re-ID may want a shared bank;
decide once cross-room AETHER traces are available.

# WiFi-DensePose: See Through Walls with WiFi + AI
**Detect people, track movement, and measure breathing -- through walls, without cameras, using a $27 sensor kit.**
| | |
|---|---|
| **License** | MIT |
| **Framework** | ONNX Runtime |
| **Hardware** | ESP32-S3 ($9) + optional Cognitum Seed ($15) |
| **Training** | Self-supervised contrastive learning (no labels needed) |
| **Privacy** | No cameras, no images, no personally identifiable data |
---
## What is this?
This model turns ordinary WiFi signals into a human sensing system. It can detect whether someone is in a room, count how many people are present, classify what they are doing, and even measure their breathing rate -- all without any cameras.
**How does it work?** Every WiFi router constantly sends signals that bounce off walls, furniture, and people. When a person moves -- or even just breathes -- those bouncing signals change in tiny but measurable ways. WiFi chips can capture these changes as numbers called *Channel State Information* (CSI). Think of it like ripples in a pond: drop a stone and the ripples tell you something happened, even if you cannot see the stone.
This model learned to read those "WiFi ripples" and figure out what is happening in the room. It was trained using a technique called *contrastive learning*, which means it taught itself by comparing thousands of WiFi signal snapshots -- no human had to manually label anything.
The result is a small, fast model that runs on a $9 microcontroller and preserves complete privacy because it never captures images or audio.
---
## What can it do?
| Capability | Accuracy | What you need | Notes |

| **Breathing rate** | +/- 2 BPM | 1x ESP32-S3 ($9) | Best when person is sitting or lying still |
| **Heart rate estimate** | +/- 5 BPM | 1x ESP32-S3 ($9) | Experimental -- less accurate during movement |

## Quick Start
### Install
```bash
pip install onnxruntime numpy
```
### Run inference
```python
import onnxruntime as ort
import numpy as np
# Load the encoder model
session = ort.InferenceSession("pretrained-encoder.onnx")
# Simulated 8-dim CSI feature vector from ESP32-S3
# Dimensions: [amplitude_mean, amplitude_std, phase_slope, doppler_energy,
# subcarrier_variance, temporal_stability, csi_ratio, spectral_entropy]
features = np.array(
[[0.45, 0.30, 0.69, 0.75, 0.50, 0.25, 0.00, 0.54]],
dtype=np.float32,
)
# Encode into 128-dim embedding
result = session.run(None, {"input": features})
embedding = result[0] # shape: (1, 128)
print(f"Embedding shape: {embedding.shape}")
print(f"First 8 values: {embedding[0][:8]}")
```
### Run task heads
```python
# Load the task heads model
heads = ort.InferenceSession("pretrained-heads.onnx")
# Feed the embedding from the encoder
predictions = heads.run(None, {"embedding": embedding})
presence_score = predictions[0] # 0.0 = empty, 1.0 = occupied
person_count = predictions[1] # estimated count (float, round to int)
activity_class = predictions[2] # [still, walking, exercise, fallen]
vitals = predictions[3] # [breathing_bpm, heart_bpm]
print(f"Presence: {presence_score[0]:.2f}")
print(f"People: {int(round(person_count[0]))}")
print(f"Activity: {['still', 'walking', 'exercise', 'fallen'][activity_class.argmax()]}")
print(f"Breathing: {vitals[0][0]:.1f} BPM")
print(f"Heart: {vitals[0][1]:.1f} BPM")
```

## Model Architecture
```
+-- Presence (binary)
|
WiFi signals --> ESP32-S3 --> 8-dim features --> Encoder (TCN) --> 128-dim embedding --> Task Heads --+-- Person Count
(CSI) (on-device) (~2.5M params) (~100K) |
+-- Activity (4 classes)
|
+-- Vitals (BR + HR)
```
### Encoder
- **Type:** Temporal Convolutional Network (TCN)
- **Input:** 8-dimensional feature vector extracted from raw CSI
- **Output:** 128-dimensional embedding
- **Parameters:** ~2.5M
- **Format:** ONNX (runs on any platform with ONNX Runtime)
### Task Heads
- **Type:** Small MLPs (multi-layer perceptrons), one per task
- **Input:** 128-dim embedding from the encoder
- **Output:** Task-specific predictions (presence, count, activity, vitals)
- **Parameters:** ~100K total across all heads
- **Format:** ONNX
### Feature extraction (runs on ESP32-S3)
The ESP32-S3 captures raw CSI frames at ~100 Hz and computes 8 summary features per window:
| Feature | Description |
|---|---|
| `amplitude_mean` | Average signal strength across subcarriers |
| `amplitude_std` | Variation in signal strength (movement indicator) |
| `phase_slope` | Rate of phase change across subcarriers |
| `doppler_energy` | Energy in the Doppler spectrum (velocity indicator) |
| `subcarrier_variance` | How much individual subcarriers differ |
| `temporal_stability` | Consistency of signal over time (stillness indicator) |
| `csi_ratio` | Ratio between antenna pairs (direction indicator) |
| `spectral_entropy` | Randomness of the frequency spectrum |
---
## Training Data
### How it was trained
This model was trained using **self-supervised contrastive learning**, which means it learned entirely from unlabeled WiFi signals. No cameras, no manual annotations, and no privacy-invasive data collection were needed.
The training process works like this:
1. **Collect** raw CSI frames from ESP32-S3 nodes placed in a room
2. **Extract** 8-dimensional feature vectors from sliding windows of CSI data
3. **Contrast** -- the model learns that features from nearby time windows should produce similar embeddings, while features from different scenarios should produce different embeddings
4. **Fine-tune** task heads using weak labels from environmental sensors (PIR motion, temperature, pressure) on the Cognitum Seed companion device
### Data provenance
- **Source:** Live CSI from 2x ESP32-S3 nodes (802.11n, HT40, 114 subcarriers)
- **Volume:** ~360,000 CSI frames (~3,600 feature vectors) per collection run
- **Environment:** Residential room, ~4x5 meters
- **Ground truth:** Environmental sensors on Cognitum Seed (PIR, BME280, light)
- **Attestation:** Every collection run produces a cryptographic witness chain (`collection-witness.json`) that proves data provenance and integrity
### Witness chain
The `collection-witness.json` file contains a chain of SHA-256 hashes linking every step from raw CSI capture through feature extraction to model training. This allows anyone to verify that the published model was trained on data collected by specific hardware at a specific time.
---
## Hardware Requirements
### Minimum: single-node sensing ($9)
| Component | What it does | Cost | Where to get it |
|---|---|---|---|
| ESP32-S3 (8MB flash) | Captures WiFi CSI + runs feature extraction | ~$9 | Amazon, AliExpress, Adafruit |
| USB-C cable | Power + data | ~$3 | Any electronics store |
This gets you: presence detection, motion classification, breathing rate.
### Recommended: dual-node sensing ($18)
Add a second ESP32-S3 to enable cross-node signal fusion for better accuracy and person counting.
### Full setup: sensing + ground truth ($27)
| Component | What it does | Cost |
|---|---|---|
| 2x ESP32-S3 (8MB) | WiFi CSI sensing nodes | ~$18 |
| Cognitum Seed (Pi Zero 2W) | Runs inference + collects ground truth | ~$15 |
| USB-C cables (x3) | Power + data | ~$9 |
| **Total** | | **~$27** |
The Cognitum Seed runs the ONNX models on-device, orchestrates the ESP32 nodes over USB serial, and provides environmental ground truth via its onboard PIR and BME280 sensors.

### RuVector format (.rvf)
The `.rvf` file contains pre-computed embeddings in RuVector format, used by the RuView application for advanced multi-node fusion and cross-viewpoint pose estimation. You only need this if you are using the full RuView pipeline. For basic inference, the ONNX files are sufficient.
---
## How to use with RuView
[RuView](https://github.com/ruvnet/RuView) is the open-source application that ties everything together: firmware flashing, real-time sensing, and a browser-based dashboard.
### 1. Flash firmware to ESP32-S3
```bash
git clone https://github.com/ruvnet/RuView.git
cd RuView
# Flash firmware (requires ESP-IDF v5.4 or use pre-built binaries from Releases)
# See the repo README for platform-specific instructions
```
### 2. Download models
```bash
pip install huggingface_hub
huggingface-cli download ruvnet/wifi-densepose-pretrained --local-dir models/
```
### 3. Run inference
```bash
# Start the CSI bridge (connects ESP32 serial output to the inference pipeline)
python scripts/seed_csi_bridge.py --port COM7 --model models/pretrained-encoder.onnx
# Or run the full sensing server with web dashboard
cargo run -p wifi-densepose-sensing-server
```
### 4. Adapt to your room
The model works best after a brief calibration period (~60 seconds of no movement) to learn the baseline signal characteristics of your specific room. The `room-profiles.json` file contains example profiles; the system will create one for your environment automatically.
---
## Limitations
Be honest about what this technology can and cannot do:
- **Room-specific.** The model needs a short calibration period in each new environment. A model calibrated in a living room will not work as well in a warehouse without re-adaptation.
- **Single room only.** There is no cross-room tracking. Each room needs its own sensing node(s).
- **Person count accuracy degrades above 4.** Counting works well for 1-3 people, becomes unreliable above 4 in a single room.
- **Vitals require stillness.** Breathing and heart rate estimation work best when the person is sitting or lying down. Accuracy drops significantly during walking or exercise.
- **Heart rate is experimental.** The +/- 5 BPM accuracy is a best-case figure. In practice, cardiac sensing via WiFi is still a research-stage capability.
- **Wall materials matter.** Metal walls, concrete reinforced with rebar, or foil-backed insulation will significantly attenuate the signal and reduce range.
- **WiFi interference.** Heavy WiFi traffic from other devices can add noise. The system works best on a dedicated or lightly-used WiFi channel.
- **Not a medical device.** Vital sign estimates are for informational and research purposes only. Do not use them for medical decisions.
---
## Use Cases
- **Elder care:** Non-invasive fall detection and activity monitoring without cameras
- **Smart home:** Presence-based lighting and HVAC control
- **Security:** Occupancy detection through walls
- **Sleep monitoring:** Breathing rate tracking overnight
- **Research:** Low-cost human sensing for academic experiments
- **Disaster response:** The MAT (Mass Casualty Assessment Tool) uses this model to detect survivors through rubble via WiFi signal reflections
---
## Ethical Considerations
WiFi sensing is a privacy-preserving alternative to cameras, but it still detects human presence and activity. Consider these points:
- **Consent:** Always inform people that WiFi sensing is active in a space.
- **No biometric identification:** This model cannot identify *who* someone is -- only that someone is present and what they are doing.
- **Data minimization:** Raw CSI data is processed on-device and only summary features or embeddings leave the sensor. No images, audio, or video are ever captured.
- **Dual use:** Like any sensing technology, this can be misused for surveillance. We encourage transparent deployment and clear signage.

### 2.2 Test Pyramid Shape Analysis
```
Ideal Pyramid Actual Shape Assessment
/\ /\
/E2E\ / 8 \ E2E: CRITICALLY THIN
/------\ /----\
/ Integ. \ / 148 \ Integration: THIN
/----------\ /--------\
/ Unit \ / 3,142 \ Unit: HEALTHY base
-------------- --------------
```
**Pyramid Ratio (unit : integration : e2e):**
- Actual: **394 : 19 : 1**
- Healthy target: **70 : 20 : 10** (percentage)
- Actual percentage: **95.3% : 4.5% : 0.2%**
**Verdict:** The pyramid is severely bottom-heavy. Unit tests are plentiful (good), but integration and E2E layers are dangerously thin relative to the project's complexity. For a multi-crate, multi-service system with hardware integration, the integration layer should be 3-4x larger, and E2E should be 10-20x larger.

**Key finding:** Python unit tests concentrate heavily on CSI extraction and processing (the hardware layer). 11 of 12 source modules have zero dedicated unit test files. The 322 unit test functions map almost entirely to `hardware/csi_extractor.py` and related signal processing code.
### 2.5 Mobile UI Test Coverage
The mobile UI has 25 test files with 202 test cases, covering:
- **Stores:** poseStore (21), matStore (18), settingsStore (13) -- good state management coverage
- **Components:** SignalBar, GaugeArc, ConnectionBanner, SparklineChart, OccupancyGrid, StatusDot, HudOverlay -- 7 components tested
- **Hooks:** useServerReachability, useRssiScanner, usePoseStream -- 3 hooks tested
- **Services:** api (14), ws (7), simulation (10), rssi (6) -- good service layer coverage
- **Screens:** MAT (4), Live (4), Vitals (5), Zones (6), Settings (6) -- all main screens tested
- **Utils:** ringBuffer (20), urlValidator (13), colorMap (9) -- thorough utility testing
**Assessment:** Mobile testing is the strongest layer relative to its codebase size. Good breadth across stores, components, services, and screens.
### 2.6 Firmware Test Coverage
| Test Type | Count | Coverage |
|-----------|-------|----------|
| Fuzz harnesses | 3 | `fuzz_csi_serialize.c`, `fuzz_edge_enqueue.c`, `fuzz_nvs_config.c` |
| Unit tests | 0 | No structured unit testing framework |
| Integration tests | 0 | No automated hardware-in-the-loop tests |
**Assessment:** The firmware has fuzz testing (a positive for security-critical embedded code), but lacks structured unit tests. The 9,445 lines of C code for a safety-relevant embedded system (disaster survivor detection via MAT) warrant stronger test coverage.

## 3. Cross-Cutting Quality Concerns
### 3.1 Code Complexity and Maintainability
| Metric | Value | Threshold | Status |
|--------|-------|-----------|--------|
| AQE quality score | 37/100 | >70 | FAIL |
| Cyclomatic complexity (avg) | 24.09 | <15 | FAIL |
| Maintainability index | 24.35 | >50 | FAIL |
| Security score | 85/100 | >80 | PASS |
**Large file risk (>500 lines in Rust src/):**
| File | Lines | Risk |
|------|-------|------|
| `sensing-server/src/main.rs` | 4,846 | Monolith risk -- nearly 10x the 500-line guideline |
| `sensing-server/src/training_api.rs` | 1,946 | High complexity |
| `wasm/src/mat.rs` | 1,673 | Hard to test, 0 tests in crate |
| `train/src/metrics.rs` | 1,664 | Complex math, needs exhaustive testing |
| `signal/src/ruvsense/pose_tracker.rs` | 1,523 | Critical path, well-tested |
| `mat/src/integration/csi_receiver.rs` | 1,401 | Integration boundary |
| `mat/src/integration/hardware_adapter.rs` | 1,360 | Hardware boundary, audit needed |
24 Rust source files exceed 500 lines, violating the project's own `CLAUDE.md` guideline.
### 3.2 Error Handling Quality (Rust)
| Pattern | Count | Assessment |
|---------|-------|------------|
| `Result<>` returns | 450 | Good -- idiomatic error handling in use |
| `.unwrap()` calls | 720 | HIGH RISK -- 720 potential panic points in production code |
| `.expect()` calls | 35 | Acceptable -- provides context on failure |
| `panic!()` calls | 1 | Good -- minimal explicit panics |
| `unsafe` blocks | 340 | NEEDS AUDIT -- high count for an application-level project |
**Critical concern:** The 720 `.unwrap()` calls represent potential runtime panics. In a system processing real-time WiFi CSI data for pose estimation (and mass casualty assessment), an unwrap failure could crash the entire pipeline. Each call should be reviewed and converted to proper error propagation with `?` operator or explicit error handling.
The 340 `unsafe` blocks are high for a project that is not a systems-level library. These need a focused audit to verify memory safety invariants are upheld, especially in signal processing and hardware interaction code.
### 3.3 Security Posture
| Check | Result | Details |
|-------|--------|---------|
| Hardcoded secrets in Python | 0 found | Clean |
| SQL injection risk (f-string SQL) | 0 found | Clean -- likely using parameterized queries |
| Python `eval()` usage | 2 calls | Safe -- both are PyTorch `model.eval()` (inference mode), not Python eval |
| Firmware buffer overflow risk | 0 `strcpy`/`sprintf` | Clean -- uses safe string functions |
| CI security scanning | Active | Bandit, Semgrep, Safety in dedicated workflow, runs daily |
| Dependency scanning | Active | Safety checks in CI |
**Security assessment: GOOD.** The project follows secure coding practices. The dedicated security-scan workflow with daily scheduling is a strong indicator of security maturity. No critical vulnerabilities detected in static analysis patterns.
### 3.4 Documentation Quality
| Metric | Value | Assessment |
|--------|-------|------------|
| Rust `///` doc comments | 11,965 | Strong |
| Rust `//!` module docs | 3,512 | Strong |
| Rust `pub fn` with docs | 1,781 / 3,912 (45.5%) | Moderate -- 54.5% of public functions lack doc comments |
| Python functions with docstrings | ~543 / ~801 (67.8%) | Good |
| Python classes with docstrings | ~121 / ~150 (80.7%) | Strong |
| ADRs | 79 | Excellent governance |
| TODO/FIXME markers | 1 (Python), 0 (Rust) | Clean -- no deferred technical debt markers |
### 3.5 CI/CD Pipeline Coverage
| Workflow | Trigger | Scope |
|----------|---------|-------|
| `ci.yml` | Push/PR to main, develop, feature/* | Python quality (Black, Flake8, MyPy), security (Bandit, Safety) |
| `cd.yml` | (deployment) | Production deployment |
| `security-scan.yml` | Push/PR + daily cron | SAST with Bandit, Semgrep; dependency scanning with Safety |
| `firmware-ci.yml` | Push/PR | ESP32 firmware build verification |
| `firmware-qemu.yml` | Push/PR | ESP32 QEMU emulation tests |
| `desktop-release.yml` | Release | Desktop application packaging |
| `verify-pipeline.yml` | Push/PR | Deterministic proof verification |
| `update-submodules.yml` | Manual/scheduled | Git submodule sync |
**Gap:** No CI workflow runs `cargo test --workspace` for the Rust codebase. The 2,618+ Rust tests appear to run only locally. This is a significant gap -- the largest and most critical codebase has no automated CI test execution.
---
## 4. Recommendations Matrix
| # | Recommendation | Priority | Effort | Impact | Domain |
|---|---------------|----------|--------|--------|--------|
| R1 | **Add Rust workspace tests to CI** -- Create a GitHub Actions workflow that runs `cargo test --workspace --no-default-features`. The 2,618 Rust tests are the project's primary safety net but run only locally. | CRITICAL | Low (1-2 days) | Very High | CI/CD |
| R2 | **Reduce `.unwrap()` calls** -- Audit and convert the 720 `.unwrap()` calls in Rust production code to proper `?` error propagation. Prioritize crates in the real-time pipeline: `signal`, `mat`, `hardware`, `sensing-server`. | CRITICAL | High (2-3 weeks) | Very High | Reliability |
| R3 | **Audit `unsafe` blocks** -- Review all 340 `unsafe` blocks. Document safety invariants for each. Consider using `unsafe_code` lint to flag new additions. | CRITICAL | Medium (1-2 weeks) | High | Security |
| R4 | **Add Python unit tests for untested modules** -- 11 of 12 Python source modules have zero unit tests. Priority targets: `api/` (3,694 LOC), `services/` (3,038 LOC), `database/` (1,715 LOC), `middleware/` (1,798 LOC). | HIGH | Medium (2-3 weeks) | High | Coverage |
| R5 | **Add integration tests for 7 Rust crates** -- `wifi-densepose-core`, `wifi-densepose-hardware`, `wifi-densepose-nn`, `wifi-densepose-ruvector`, `wifi-densepose-vitals`, `wifi-densepose-wifiscan`, `wifi-densepose-cli` have unit tests but no integration test directory. | HIGH | Medium (2 weeks) | High | Coverage |
| R6 | **Break up `sensing-server/src/main.rs`** (4,846 lines) -- Extract route handlers, middleware, and configuration into separate modules. This single file is nearly 10x the project's 500-line guideline. | HIGH | Medium (1 week) | Medium | Maintainability |
| R7 | **Add E2E tests** -- Only 1 E2E test file exists (`test_healthcare_scenario.py` with 8 tests). For a system with REST API, WebSocket streaming, hardware integration, and mobile clients, E2E coverage is critically insufficient. | HIGH | High (3-4 weeks) | Very High | Coverage |
| R8 | **Add tests to `wifi-densepose-wasm`** (1,805 LOC, 0 tests) -- This crate contains MAT WebAssembly bindings used in browser deployment. Zero test coverage for a user-facing interface is unacceptable. | HIGH | Low (3-5 days) | Medium | Coverage |
| R9 | **Add firmware unit tests** -- Adopt a C unit test framework (Unity, CMock, or CTest) for the 9,445 lines of ESP32 firmware. The fuzz harnesses are a good start but do not substitute for structured unit tests. | MEDIUM | Medium (2 weeks) | Medium | Coverage |
| R10 | **Improve Rust public API documentation** -- 54.5% of `pub fn` declarations lack doc comments. Add `#![warn(missing_docs)]` to crate lib.rs files to enforce documentation. | MEDIUM | Medium (1-2 weeks) | Medium | Documentation |
| R11 | **Add `rustfmt.toml`** -- No Rust formatting configuration found. Add workspace-level `rustfmt.toml` and enforce in CI with `cargo fmt --check`. | LOW | Low (1 day) | Low | Consistency |
| R12 | **Reduce cyclomatic complexity** -- Average complexity of 24.09 is well above the 15 threshold. Target the 24 files over 500 lines for refactoring. | MEDIUM | High (3-4 weeks) | High | Maintainability |
---
## 5. Overall Quality Score
### 5.1 Scoring Methodology
Weighted scoring across 8 dimensions, each rated 0-100:
| Dimension | Weight | Score | Weighted | Rationale |
|-----------|--------|-------|----------|-----------|
| Unit test coverage | 20% | 68 | 13.6 | 3,142 unit tests is strong for Rust/mobile, but Python modules severely undertested |
| Integration test coverage | 15% | 32 | 4.8 | Only 7 of 19 Rust crates have integration tests; Python integration tests exist but skip core modules |
| E2E test coverage | 10% | 8 | 0.8 | 1 E2E file with 8 tests for a multi-platform system is critically insufficient |
| Security posture | 15% | 82 | 12.3 | Strong CI security scanning, clean code patterns, daily Bandit/Semgrep/Safety; offset by 340 unsafe blocks needing audit |
| Code quality / complexity | 15% | 35 | 5.3 | AQE score 37/100, 720 unwraps, 24 oversized files, high cyclomatic complexity |
| CI/CD maturity | 10% | 55 | 5.5 | 8 workflows is good breadth, but missing Rust test execution in CI is a major gap |
| Documentation | 10% | 78 | 7.8 | 79 ADRs, strong docstrings in Python, moderate Rust doc coverage, witness bundles |
| Architecture governance | 5% | 90 | 4.5 | Exemplary ADR practice, DDD bounded contexts, deterministic verification pipeline |

### 5.3 Summary Assessment
**Strengths:**
- Exceptional architecture governance with 79 ADRs and deterministic verification (witness bundles)
- Strong Rust unit test count (2,618) with good distribution across signal processing and training crates
- Mature security CI pipeline with daily scheduled scanning (Bandit, Semgrep, Safety)
- Mobile UI has the best test-to-code ratio in the entire project
- No hardcoded secrets, no unsafe string operations in firmware, clean security patterns
**Critical Gaps:**
- Rust tests do not run in CI -- the 2,618 tests are only a local safety net
- 720 `.unwrap()` calls create panic risk in production signal processing pipelines
- 340 `unsafe` blocks need formal audit with documented safety invariants
- 11 of 12 Python source modules have zero unit tests
- Only 8 E2E test functions for a multi-platform, multi-service system
- `sensing-server/main.rs` at 4,846 lines is a monolith risk
**Path to Release Readiness (target: 75/100):**
1. Add Rust CI workflow (+10 points to CI maturity)
2. Add Python unit tests for top 4 untested modules (+8 points to unit coverage)
3. Audit and reduce `.unwrap()` count by 50% (+5 points to code quality)
4. Add 5+ E2E test scenarios (+4 points to E2E coverage)
5. Add integration tests to `core`, `hardware`, `nn` crates (+5 points to integration coverage)

# Code Quality and Complexity Analysis Report
**Project:** wifi-densepose (ruview)
**Date:** 2026-04-05
**Analyzer:** QE Code Complexity Analyzer v3
**Scope:** Full codebase -- Rust, Python, C firmware, TypeScript/React Native
---
## Executive Summary
This report analyzes code complexity across the entire wifi-densepose project --
153,139 lines of Rust, 21,399 lines of Python, 7,987 lines of C firmware, and
7,457 lines of TypeScript/React Native. The analysis identified **231 Rust
functions with cyclomatic complexity > 10**, a single 4,846-line Rust file that
constitutes the most critical hotspot in the entire codebase, and systematic
code duplication patterns that inflate maintenance cost.
### Key Findings
| Metric | Rust | Python | C Firmware | TypeScript |
|--------|------|--------|------------|------------|
| Source files | 379 | 63 | 32 | 71 |
| Total lines | 153,139 | 21,399 | 7,987 | 7,457 |

| Max nesting > 4 | 215 (3.2%) | 7 (0.8%) | 4 (2.8%) | 2 (2.1%) |
### Overall Quality Score: 62/100 (MODERATE)
The Python and TypeScript codebases are well-structured. The Rust codebase has
pockets of extreme complexity concentrated in the sensing server, and the C
firmware has proportionally the highest rate of complex functions.

| Rank | CC | Lines | Depth | Function | File | Line |
|------|-----|-------|-------|----------|------|------|
| 1 | 121 | 776 | 8 | `main` | sensing-server/src/main.rs | 4070 |

| 20 | 31 | 125 | 5 | `process_frame` | wasm-edge/src/ret_dwell_heatmap.rs | 116 |
### 1.3 Critical Hotspot: `sensing-server/src/main.rs` (4,846 lines)
This is the single worst file in the entire codebase. At 4,846 lines, it is
**9.7x the project's 500-line guideline** and contains:
**God Object: `AppStateInner`** (lines 424-525)
- 40+ fields spanning unrelated concerns: vital signs, recording state, training
state, adaptive model, per-node state, field model calibration, model management
- Violates Single Responsibility Principle -- mixes signal processing state,
application lifecycle, network I/O, and persistence concerns
**Monolithic `main()` function** (lines 4070-4846)
- CC=121, 776 lines, nesting depth 8
- Handles CLI dispatch (benchmark, export, pretrain, embed, build-index, train,
server startup) all in one function
- Should be decomposed into at least 8 separate command handlers
**`udp_receiver_task()` function** (lines 3504-3926)
- CC=66, 422 lines, nesting depth 8
- Handles three different packet types (vitals 0xC511_0002, WASM 0xC511_0004,
CSI 0xC511_0001) in a single monolithic match chain
- Each branch duplicates the full sensing update construction and broadcast logic
**Systematic Code Duplication (6 instances):**
- `smooth_and_classify` / `smooth_and_classify_node` -- identical logic, differs
only in operating on `AppStateInner` vs `NodeState` (could use a trait)
- `smooth_vitals` / `smooth_vitals_node` -- same pattern, identical algorithm
duplicated for `AppStateInner` vs `NodeState`
- `SensingUpdate` construction -- built identically in 6 different places
(WiFi task, WiFi fallback, simulate task, ESP32 CSI handler, ESP32 vitals
handler, broadcast tick)
- Person count estimation -- repeated in WiFi, ESP32, and simulate paths
### 1.4 Code Smell: `wasm-edge` Vendor Modules
The `wifi-densepose-wasm-edge` crate contains 68 files (28,888 lines), with
nearly every module implementing a `process_frame` function following the same
pattern. At least 20 of these have CC > 25. This is a textbook case for:
- Extracting a common `process_frame` trait with shared scaffolding
- Using a generic signal pipeline builder
### 1.5 Oversized Rust Files (> 500 lines, violating project guideline)
92 Rust files exceed the 500-line guideline. The worst offenders:
| Lines | File |
|-------|------|
| 4,846 | sensing-server/src/main.rs |
| 1,946 | sensing-server/src/training_api.rs |
| 1,673 | wasm/src/mat.rs |
| 1,664 | train/src/metrics.rs |
| 1,523 | signal/src/ruvsense/pose_tracker.rs |
| 1,498 | sensing-server/src/embedding.rs |
| 1,430 | ruvector/src/crv/mod.rs |
| 1,401 | mat/src/integration/csi_receiver.rs |
| 1,360 | mat/src/integration/hardware_adapter.rs |
| 1,346 | signal/src/ruvsense/field_model.rs |
### 1.6 Dependency Analysis
No circular dependencies detected. The dependency graph is clean and follows
the documented crate publishing order. Maximum depth is 3 (CLI -> MAT -> core/signal/nn).
---
## 2. Python Codebase (21,399 lines, 63 files)
### 2.1 Overall Assessment: GOOD
The Python codebase is significantly better structured than the Rust codebase.
Only 16 functions (1.8%) exceed CC=10, and no function exceeds CC=20. The code
follows clean separation of concerns with distinct layers (api, services, core,
hardware, middleware, sensing).
### 2.2 Top 10 Most Complex Python Functions
| Rank | CC | Lines | Depth | Function | File | Line |
|------|-----|-------|-------|----------|------|------|
| 1 | 19 | 90 | 4 | `estimate_poses` | services/pose_service.py | 491 |
| 2 | 18 | 126 | 6 | `_print_text_status` | commands/status.py | 350 |
| 3 | 15 | 72 | 4 | `websocket_events_stream` | api/routers/stream.py | 156 |
| 4 | 14 | 100 | 3 | `health_check` | database/connection.py | 349 |
| 5 | 14 | 47 | 3 | `get_overall_health` | services/health_check.py | 384 |
| 6 | 13 | 52 | 3 | `_authenticate_request` | middleware/auth.py | 236 |
| 7 | 13 | 64 | 4 | `_handle_preflight` | middleware/cors.py | 89 |
| 8 | 13 | 84 | 4 | `websocket_pose_stream` | api/routers/stream.py | 69 |
| 9 | 13 | 65 | 4 | `generate_signal_field` | sensing/ws_server.py | 236 |
| 10 | 13 | 74 | 6 | `create_collector` | sensing/rssi_collector.py | 770 |
### 2.3 Files Exceeding 500 Lines
| Lines | File | Concern |
|-------|------|---------|
| 856 | services/pose_service.py | Pose estimation service -- acceptable for a service class |
| 843 | sensing/rssi_collector.py | RSSI collection with 3 collector implementations |
| 772 | tasks/monitoring.py | Background monitoring tasks |
| 640 | database/connection.py | Database connection management |
| 620 | cli.py | CLI command handler |
| 610 | tasks/backup.py | Backup task logic |
| 598 | tasks/cleanup.py | Cleanup task logic |
| 519 | sensing/ws_server.py | WebSocket server |
| 515 | hardware/csi_extractor.py | CSI data extraction |
| 510 | commands/status.py | Status reporting |
| 504 | middleware/error_handler.py | Error handling middleware |
### 2.4 Observations
- **Well-typed**: Uses type hints consistently throughout
- **Clean separation**: API routers, services, core, and middleware are distinct
- **Moderate nesting**: Only 7 functions (0.8%) exceed nesting depth 4
- **Minor concern**: `_print_text_status` (CC=18, 126 lines) in `commands/status.py`
is essentially a large formatting function that could be split into per-component
formatters
---
## 3. C Firmware (7,987 lines, 32 files)
### 3.1 Overall Assessment: MODERATE
The C firmware has the highest proportion of complex functions (15.2% with CC>10).
This is partly expected for embedded C, but several functions warrant attention.
### 3.2 Top 10 Most Complex C Functions
| Rank | CC | Lines | Depth | Function | File | Line |
|------|-----|-------|-------|----------|------|------|
| 1 | 59 | 314 | 3 | `nvs_config_load` | nvs_config.c | 19 |

| 6 | 21 | 136 | 3 | `rvf_parse` | rvf_parser.c | 33 |
| 7 | 19 | 119 | 3 | `wasm_runtime_load` | wasm_runtime.c | 442 |
| 8 | 18 | 84 | 3 | `send_vitals_packet` | edge_processing.c | 554 |
| 9 | 17 | 74 | 4 | `update_multi_person_vitals` | edge_processing.c | 474 |
| 10 | 17 | 34 | 3 | `ld2410_feed_byte` | mmwave_sensor.c | 274 |
### 3.3 Critical Hotspot: `nvs_config_load` (CC=59, 314 lines)
This function in `nvs_config.c` has the highest complexity of any C function.
It loads 30+ configuration parameters from NVS flash storage, each with its own
error handling and default-value fallback. This is a classic case for:
- Table-driven configuration loading with a descriptor array
- Macro-based parameter definition to eliminate repetition
### 3.4 `edge_processing.c` (1,067 lines)
This is the only C file exceeding 1,000 lines. It implements the full dual-core
CSI processing pipeline (11 processing stages). The `process_frame` function
(CC=40, 185 lines) combines phase extraction, variance tracking, subcarrier
selection, bandpass filtering, BPM estimation, presence detection, and fall
detection in a single function.
### 3.5 Stack Safety Concern
The code documents that `process_frame` + `update_multi_person_vitals` combined
used 6.5-7.5 KB of the 8 KB task stack, necessitating static scratch buffers.
This indicates the functions are pushing resource limits and should be
decomposed for safety margin.
---
## 4. TypeScript/React Native (7,457 lines, 71 files)
### 4.1 Overall Assessment: GOOD
The UI codebase is the cleanest in the project. Only 3 functions exceed CC=10,
no file exceeds 1,000 lines, and the component architecture follows React
best practices with proper separation of screens, components, stores, and services.
### 4.2 Critical Hotspot: `GaussianSplatWebView.web.tsx` (CC=70, 747 lines)
This is the only significant complexity hotspot in the TypeScript codebase.
The `GaussianSplatWebViewWeb` component (CC=70, 467 lines) manages:
- Three.js scene initialization and teardown
- Multi-person skeleton rendering with DensePose-style body parts
- Signal field visualization
- Animation loop management
- Frame data parsing and keypoint mapping
This component should be decomposed into:
- A Three.js scene manager (initialization, camera, lighting, animation)
- A skeleton renderer (body parts, keypoints, bones)
- A signal field renderer (grid, heatmap)
- A data adapter (frame parsing, person mapping)
### 4.3 Well-Structured Patterns
- **Zustand stores** (`poseStore.ts`, `matStore.ts`, `settingsStore.ts`): Clean
state management with proper typing
- **Custom hooks** (`useMatBridge`, `useOccupancyGrid`, `useGaussianBridge`):
Good separation of WebSocket logic from UI components
- **Component decomposition**: Screens are split into sub-components
(AlertCard, SurvivorCounter, MetricCard, etc.)

## 6. Code Smell Catalog
### 6.1 God Class / God File
| Smell | Location | Severity |
|-------|----------|----------|
| God File | sensing-server/main.rs (4,846 lines) | CRITICAL |
| God Object | `AppStateInner` (40+ fields) | CRITICAL |
| God Function | `main()` (776 lines, CC=121) | CRITICAL |
| God Function | `udp_receiver_task()` (422 lines, CC=66) | HIGH |
### 6.2 Duplicated Code
| Pattern | Instances | Lines Duplicated | Severity |
|---------|-----------|-----------------|----------|
| `smooth_and_classify` / `smooth_and_classify_node` | 2 | ~50 per copy | HIGH |
| `smooth_vitals` / `smooth_vitals_node` | 2 | ~50 per copy | HIGH |
| `SensingUpdate {}` construction | 6 | ~40 per instance | HIGH |
| Person count estimation pattern | 3+ | ~15 per instance | MEDIUM |
| `frame_history` capacity check | 6+ | ~3 per instance | LOW |
| `tracker_bridge::tracker_update` call pattern | 5 | ~5 per instance | MEDIUM |
Estimated duplicated code in `main.rs` alone: **~450 lines** (9.3% of file).
### 6.3 Deep Nesting (> 4 levels)
215 Rust functions exceed 4 levels of nesting. The worst cases:
- `main()`: 8 levels (lines 4070-4846)
- `udp_receiver_task()`: 8 levels (lines 3504-3926)
- Multiple `process_frame` in wasm-edge: 7-8 levels
### 6.4 Long Parameter Lists (> 5 parameters)
43 Rust functions have more than 5 parameters. Notable:
- `process_frame` variants in wasm-edge: 5-7 parameters each
- `extract_features_from_frame`: 3 parameters but returns a 5-tuple
### 6.5 Repetitive Vendor Modules (wasm-edge)
The `wifi-densepose-wasm-edge` crate has 68 files following a near-identical
pattern. At least 35 have a `process_frame` function with CC > 20. A trait-based
or macro-based approach would reduce this to a fraction of the code.

---
## 8. Refactoring Recommendations
### Priority 1: CRITICAL -- sensing-server/main.rs Decomposition
**Estimated effort:** 3-5 days
**Impact:** Reduces maintenance cost for the most-changed file in the project
1. **Extract `AppStateInner` into bounded contexts:**
- `SensingState` -- frame history, features, classification
- `VitalSignState` -- HR/BR smoothing, detector, buffers
- `RecordingState` -- recording lifecycle, file handles
- `TrainingState` -- training status, config
- `ModelState` -- loaded model, progressive loader, SONA profiles
- `NodeRegistry` -- per-node states, pose tracker, multistatic fuser
2. **Extract command handlers from `main()`:**
- `run_benchmark()` (lines 4082-4089)
- `run_export_rvf()` (lines 4092-4142)
- `run_pretrain()` (lines 4145-4247)
- `run_embed()` (lines 4250-4312)
- `run_build_index()` (lines 4315-4357)
- `run_train()` (lines 4360-end)
- `run_server()` -- the remaining server startup
3. **Extract `SensingUpdate` builder:**
Create a `SensingUpdateBuilder` that encapsulates the repeated 6-instance
construction pattern.
4. **Unify node vs global variants via trait:**
```rust
trait SmoothingState {
fn smoothed_motion(&self) -> f64;
fn set_smoothed_motion(&mut self, v: f64);
// ... etc
}
impl SmoothingState for AppStateInner { ... }
impl SmoothingState for NodeState { ... }
```
Then a single `smooth_and_classify<S: SmoothingState>()` replaces both copies.
5. **Extract `udp_receiver_task` into packet-type handlers:**
- `handle_vitals_packet()`
- `handle_wasm_packet()`
- `handle_csi_frame()`
### Priority 2: HIGH -- C Firmware `nvs_config_load` Table-Driven Refactor
**Estimated effort:** 1 day
**Impact:** Reduces CC from 59 to approximately 5
Replace the 314-line sequential NVS load with a descriptor table:
```c
typedef struct {
const char *key;
nvs_type_t type;
void *dest;
size_t size;
const void *default_val;
} nvs_param_desc_t;
static const nvs_param_desc_t params[] = {
{"node_id", NVS_U8, &cfg->node_id, 1, &(uint8_t){1}},
// ... 30+ entries
};
```
### Priority 3: HIGH -- wasm-edge `process_frame` Trait Extraction
**Estimated effort:** 2-3 days
**Impact:** Reduces 28,888 lines by an estimated 30-40%
Define a common trait:
```rust
trait WasmEdgeModule {
fn name(&self) -> &str;
fn init(&mut self, config: &ModuleConfig);
fn process_frame(&mut self, ctx: &mut FrameContext) -> Vec<WasmEvent>;
}
```
Extract shared signal processing (phase extraction, variance tracking, BPM
estimation) into reusable pipeline stages.
### Priority 4: MEDIUM -- GaussianSplatWebView.web.tsx Decomposition
**Estimated effort:** 1 day
**Impact:** Reduces CC from 70 to approximately 10-15 per component
Split into:
- `SceneManager` -- Three.js initialization, camera, lighting
- `SkeletonRenderer` -- body parts, keypoints, bones
- `SignalFieldRenderer` -- grid, heatmap visualization
- `useFrameAdapter` -- data parsing hook
### Priority 5: MEDIUM -- `edge_processing.c` Pipeline Decomposition
**Estimated effort:** 1-2 days
**Impact:** Reduces `process_frame` CC from 40 to ~10; improves stack safety
Split into stage functions:
```c
static void stage_phase_extract(frame_ctx_t *ctx);
static void stage_variance_update(frame_ctx_t *ctx);
static void stage_subcarrier_select(frame_ctx_t *ctx);
static void stage_bandpass_filter(frame_ctx_t *ctx);
static void stage_bpm_estimate(frame_ctx_t *ctx);
static void stage_presence_detect(frame_ctx_t *ctx);
static void stage_fall_detect(frame_ctx_t *ctx);
```
### Priority 6: LOW -- Python Status Formatter Decomposition
**Estimated effort:** 0.5 days
**Impact:** Reduces `_print_text_status` CC from 18 to ~5 per formatter
Split `_print_text_status` (126 lines) into per-component formatters:
`_format_api_status`, `_format_hardware_status`, `_format_streaming_status`, etc.
---
## 9. Quality Gate Recommendations
### Proposed Complexity Thresholds for CI/CD
| Metric | Warn | Fail | Current Violations |
|--------|------|------|--------------------|
| File size | > 500 lines | > 1,000 lines | 92 warn, 25 fail |
| Function CC | > 15 | > 25 | ~150 warn, ~74 fail |
| Function lines | > 50 | > 100 | ~360 warn, ~94 fail |
| Nesting depth | > 4 | > 6 | ~215 warn, ~30 fail |
| Parameter count | > 5 | > 7 | ~43 warn, ~10 fail |
### Recommended Immediate Actions
1. **Block new functions with CC > 25** in CI (addresses future growth)
2. **Block new files exceeding 500 lines** (enforces project guideline)
3. **Add complexity linting** via `cargo clippy` with custom lints or `complexity-rs`
4. **Prioritize the sensing-server decomposition** -- it is the single largest
contributor to technical debt in the project

## Appendix A: Methodology
### Metrics Calculated
- **Cyclomatic Complexity (CC):** McCabe's cyclomatic complexity counting
decision points (if, else if, match, for, while, boolean operators, match arms)
- **Cognitive Complexity:** Approximated via nesting depth and CC combination
- **Function Length:** Raw line count from function signature to closing brace
- **Nesting Depth:** Maximum brace/indent depth within function body
- **Parameter Count:** Number of non-self parameters
- **File Size:** Total lines including comments and blank lines
### Tools Used
- Custom Python AST analysis for Python files
- Custom regex-based analysis for Rust, C, and TypeScript files
- AST parsing provides higher accuracy for Python; regex-based analysis may
slightly overcount CC for Rust (e.g., match arms in comments) but provides
consistent cross-language comparison
### Limitations
- CC for Rust match arms counted via `=>` may include non-decision match arms
- TypeScript analysis captures top-level and exported functions but may miss
deeply nested callbacks
- C analysis requires function signatures to start at column 0
- Dead code detection is heuristic-only (unused imports not checked at scale)

# Security Review Report -- wifi-densepose
**Date:** 2026-04-05
**Reviewer:** QE Security Reviewer (V3)
**Scope:** Full codebase -- Python API, Rust crates, ESP32 C firmware
**Severity Weights:** CRITICAL=3, HIGH=2, MEDIUM=1, LOW=0.5, INFORMATIONAL=0.25
**Weighted Finding Score:** 19.25 (minimum required: 3.0)
---
## Executive Summary
This security review examined all security-sensitive code across the wifi-densepose project: the Python FastAPI backend (authentication, rate limiting, CORS, WebSocket, API endpoints), Rust workspace crates (API, DB, config, WASM), and ESP32-S3 C firmware (NVS credentials, OTA update, WASM upload, swarm bridge, UDP streaming).
**Recommendation: CONDITIONAL PASS** -- No critical data-exfiltration or remote code execution vulnerabilities were found in the production code paths. However, 3 HIGH severity findings and several MEDIUM issues require remediation before any production deployment. The codebase demonstrates solid security awareness in many areas (constant-time OTA PSK comparison, Ed25519 WASM signature verification, parameterized queries via SQLAlchemy/sqlx, bcrypt password hashing), but gaps remain in WebSocket security, rate limiting bypass vectors, and firmware transport encryption.
---
## Vulnerability Summary
| Severity | Count | Categories |
|----------|-------|------------|
| CRITICAL | 0 | -- |
| HIGH | 3 | Auth bypass, information disclosure, IP spoofing |
| MEDIUM | 7 | CORS, token lifecycle, transport security, memory growth |
| LOW | 5 | Deprecated APIs, logging, configuration hardening |
| INFORMATIONAL | 3 | Best practice improvements |
---
## Detailed Findings
### HIGH-001: WebSocket Authentication Token Passed in URL Query String (CWE-598)
**Severity:** HIGH
**OWASP:** A07:2021 -- Identification and Authentication Failures
**Files:**
- `archive/v1/src/api/routers/stream.py:74` (WebSocket `token` query parameter)
- `archive/v1/src/middleware/auth.py:243` (fallback to `request.query_params.get("token")`)
- `archive/v1/src/api/middleware/auth.py:173` (`request.query_params.get("token")`)
**Description:**
JWT tokens are accepted via URL query parameters for WebSocket connections. URL parameters are logged in web server access logs, browser history, proxy logs, and HTTP Referer headers. This creates multiple credential leakage vectors.
```python
# archive/v1/src/api/routers/stream.py:74
token: Optional[str] = Query(None, description="Authentication token")
```
```python
# archive/v1/src/middleware/auth.py:243
if request.url.path.startswith("/ws"):
token = request.query_params.get("token")
```
**Impact:** JWT tokens may be captured from server logs, proxy caches, or browser history, enabling session hijacking.
**Remediation:**
1. Use the WebSocket `Sec-WebSocket-Protocol` header to pass tokens during the upgrade handshake.
2. Alternatively, require clients to send the token as the first WebSocket message after connection, then authenticate before processing further messages.
3. If query parameter tokens must be supported during a transition, ensure all web server and reverse proxy log configurations redact the `token` parameter.
---
### HIGH-002: Rate Limiter Trusts X-Forwarded-For Header Without Validation (CWE-348)
**Severity:** HIGH
**OWASP:** A05:2021 -- Security Misconfiguration
**File:** `archive/v1/src/middleware/rate_limit.py:200-206`
**Description:**
The `_get_client_ip` method trusts the `X-Forwarded-For` header without any validation. An attacker can spoof this header to bypass IP-based rate limiting entirely by rotating forged IP addresses on each request.
```python
# archive/v1/src/middleware/rate_limit.py:200-206
def _get_client_ip(self, request: Request) -> str:
forwarded_for = request.headers.get("X-Forwarded-For")
if forwarded_for:
return forwarded_for.split(",")[0].strip()
real_ip = request.headers.get("X-Real-IP")
if real_ip:
return real_ip
return request.client.host if request.client else "unknown"
```
**Impact:** Complete rate limiting bypass for unauthenticated requests. An attacker can send unlimited requests by setting arbitrary `X-Forwarded-For` values.
**Remediation:**
1. Only trust `X-Forwarded-For` when the application is deployed behind a known reverse proxy. Configure a trusted proxy allowlist.
2. Use the uvicorn/Starlette `--proxy-headers` flag only when behind a trusted proxy, and strip these headers at the edge.
3. Consider using a middleware like `starlette.middleware.trustedhost.TrustedHostMiddleware` and validating the number of proxy hops.
---
### HIGH-003: Error Responses Leak Internal Exception Details in Non-Production (CWE-209)
**Severity:** HIGH
**OWASP:** A09:2021 -- Security Logging and Monitoring Failures
**Files:**
- `archive/v1/src/api/routers/pose.py:140-141` -- `detail=f"Pose estimation failed: {str(e)}"`
- `archive/v1/src/api/routers/pose.py:176-177` -- `detail=f"Pose analysis failed: {str(e)}"`
- `archive/v1/src/api/routers/stream.py:297` -- `detail=f"Failed to get stream status: {str(e)}"`
- All exception handlers in `archive/v1/src/api/routers/stream.py` (lines 326, 351, 404, 442, 463)
- `archive/v1/src/middleware/error_handler.py:101-104` -- traceback in development mode
**Description:**
Multiple API endpoints directly interpolate Python exception messages into HTTP error responses. While the global error handler in `error_handler.py` correctly suppresses details in production, the per-endpoint `HTTPException` handlers bypass this and always expose `str(e)` regardless of environment.
```python
# archive/v1/src/api/routers/pose.py:140-141
raise HTTPException(
status_code=500,
detail=f"Pose estimation failed: {str(e)}"
)
```
**Impact:** Internal error messages (including database connection strings, file paths, stack traces, and library-specific error codes) are exposed to unauthenticated callers. This aids reconnaissance for targeted attacks.
**Remediation:**
1. Replace all endpoint-level `detail=f"...{str(e)}"` patterns with a generic message: `detail="Internal server error"`.
2. Log the full exception server-side with `logger.exception()`.
3. Rely on the centralized `ErrorHandler` class for all error formatting, which already has production-safe behavior.
---
### MEDIUM-001: CORS Allows Wildcard Origins with Credentials in Development (CWE-942)
**Severity:** MEDIUM
**OWASP:** A05:2021 -- Security Misconfiguration
**Files:**
- `archive/v1/src/config/settings.py:33-34` -- defaults: `cors_origins=["*"]`, `cors_allow_credentials=True`
- `archive/v1/src/middleware/cors.py:255-256` -- development config combines `allow_origins=["*"]` + `allow_credentials=True`
**Description:**
The default settings allow CORS from all origins (`*`) with credentials (`allow_credentials=True`). Per the CORS specification, `Access-Control-Allow-Origin: *` cannot be used with `Access-Control-Allow-Credentials: true`. However, the `CORSMiddleware` implementation echoes the requesting origin header verbatim, effectively granting credentialed access from any origin.
```python
# archive/v1/src/middleware/cors.py:255-256 (development_config)
"allow_origins": ["*"],
"allow_credentials": True,
```
The `validate_cors_config` function at line 354 correctly flags this combination but is only advisory -- it does not prevent the configuration from being applied.
**Impact:** Any website can make authenticated cross-origin requests to the API when running in development mode. If development defaults leak to production, this becomes a credential theft vector via CSRF-like attacks.
**Remediation:**
1. Change the default `cors_origins` to `[]` (empty list) and require explicit configuration.
2. Make `validate_cors_config` enforce the rule by raising an exception rather than returning warnings.
3. In the `CORSMiddleware.__init__`, reject the combination of `allow_credentials=True` with wildcard origins at construction time.
---
### MEDIUM-002: WebSocket Connections Lack Message Size Limits (CWE-400)
**Severity:** MEDIUM
**OWASP:** A04:2021 -- Insecure Design
**Files:**
- `archive/v1/src/api/routers/stream.py:127-128` -- `message = await websocket.receive_text()` with no size limit
- `archive/v1/src/api/websocket/connection_manager.py` -- no `max_size` configuration
**Description:**
WebSocket endpoints accept incoming messages of arbitrary size. The `receive_text()` call at `stream.py:127` has no size limit, allowing a client to send extremely large messages that consume server memory.
Additionally, the `ConnectionManager` does not enforce a maximum number of connections. An attacker could open thousands of WebSocket connections to exhaust server resources.
**Impact:** Denial of service through memory exhaustion or connection pool exhaustion.
**Remediation:**
1. Configure `websocket.accept(max_size=...)` or use Starlette's `WebSocket` `max_size` parameter (default is 16 MB -- reduce to 64 KB or less for control messages).
2. Add a maximum connection limit in `ConnectionManager.connect()` and reject new connections when the limit is reached.
3. Implement per-client message rate limiting in the WebSocket handler.
---
### MEDIUM-003: Token Blacklist Uses Periodic Full Clear Instead of Per-Token Expiry (CWE-613)
**Severity:** MEDIUM
**OWASP:** A07:2021 -- Identification and Authentication Failures
**File:** `archive/v1/src/api/middleware/auth.py:246-252`
**Description:**
The `TokenBlacklist` class clears all blacklisted tokens every hour, regardless of their actual expiry time. This means:
1. A revoked token could be re-usable after the next hourly clear.
2. Tokens revoked just before a clear cycle have nearly zero effective blacklist time.
```python
# archive/v1/src/api/middleware/auth.py:246-252
def _cleanup_if_needed(self):
now = datetime.utcnow()
if (now - self._last_cleanup).total_seconds() > self._cleanup_interval:
self._blacklisted_tokens.clear() # Clears ALL tokens
self._last_cleanup = now
```
Furthermore, the `TokenBlacklist` is not consulted in the `AuthMiddleware.dispatch()` or `AuthenticationMiddleware._authenticate_request()` flows -- the `token_blacklist` global instance exists but is never checked during token validation.
**Impact:** Token revocation (logout) is not enforceable. A stolen JWT remains valid until its natural expiry.
**Remediation:**
1. Store each blacklisted token with its `exp` claim timestamp. Only remove entries whose `exp` has passed.
2. Integrate the blacklist check into `_verify_token()` / `verify_token()` so that blacklisted tokens are rejected.
3. For production, replace the in-memory set with a Redis-backed store for cross-process consistency.

### MEDIUM-004: OTA Update Endpoint Has No Authentication by Default (CWE-306)
**Severity:** MEDIUM
**OWASP:** A07:2021 -- Identification and Authentication Failures
**File:** `firmware/esp32-csi-node/main/ota_update.c:44-49`
**Description:**
The OTA firmware update endpoint (`POST /ota` on port 8032) has authentication disabled unless an OTA pre-shared key (PSK) is manually provisioned into NVS. The `ota_check_auth` function returns `true` when no PSK is configured, allowing unauthenticated firmware uploads.
```c
// firmware/esp32-csi-node/main/ota_update.c:44-49
static bool ota_check_auth(httpd_req_t *req)
{
if (s_ota_psk[0] == '\0') {
/* No PSK provisioned -- auth disabled (permissive for dev). */
return true;
}
...
}
```
The firmware logs a warning about this (`ESP_LOGW(..., "OTA authentication DISABLED")`), but it is the default state for all new devices.
**Impact:** Any device on the same network can flash arbitrary firmware to the ESP32 without authentication, enabling persistent compromise of the sensing node.
**Remediation:**
1. Require PSK provisioning as part of the mandatory device setup flow. Reject OTA uploads if no PSK is provisioned (fail-closed).
2. Alternatively, require physical button press confirmation for OTA updates when no PSK is set.
3. Document the PSK provisioning step prominently in the deployment guide.

### MEDIUM-005: ESP32 UDP CSI Stream Has No Encryption or Authentication (CWE-319)
**Severity:** MEDIUM
**OWASP:** A02:2021 -- Cryptographic Failures
**File:** `firmware/esp32-csi-node/main/stream_sender.c:66-106`
**Description:**
CSI data frames are transmitted via plain UDP (`SOCK_DGRAM, IPPROTO_UDP`) with no encryption, authentication, or integrity protection. An attacker on the same network segment can:
1. Eavesdrop on CSI data (potentially revealing occupancy/activity information).
2. Inject forged CSI frames to manipulate pose estimation.
3. Replay captured frames.
```c
// firmware/esp32-csi-node/main/stream_sender.c:92-93
int sent = sendto(s_sock, data, len, 0,
(struct sockaddr *)&s_dest_addr, sizeof(s_dest_addr));
```
**Impact:** CSI data exposure and injection on the local network. The severity is moderated by the fact that CSI data requires specialized knowledge to interpret, but the UDP transport provides zero confidentiality for the sensor data.
**Remediation:**
1. Implement DTLS (Datagram TLS) for the UDP stream, using mbedTLS which is already available in ESP-IDF.
2. At minimum, add HMAC authentication to each frame using a pre-shared key to prevent injection.
3. Consider adding a sequence number and replay window to detect replayed frames.

### MEDIUM-006: Swarm Bridge Seed Token Transmitted in Cleartext HTTP (CWE-319)
**Severity:** MEDIUM
**OWASP:** A02:2021 -- Cryptographic Failures
**File:** `firmware/esp32-csi-node/main/swarm_bridge.c:211-229`
**Description:**
The swarm bridge HTTP client configuration does not enforce TLS. The `esp_http_client_config_t` struct at line 211 specifies only `.url` and `.timeout_ms` without setting `.transport_type = HTTP_TRANSPORT_OVER_SSL` or `.cert_pem`. If the `seed_url` uses `http://` rather than `https://`, the Bearer token is transmitted in cleartext.
```c
// firmware/esp32-csi-node/main/swarm_bridge.c:211-216
esp_http_client_config_t http_cfg = {
.url = url,
.method = HTTP_METHOD_POST,
.timeout_ms = SWARM_HTTP_TIMEOUT,
};
```
```c
// firmware/esp32-csi-node/main/swarm_bridge.c:226-229
if (s_cfg.seed_token[0] != '\0') {
char auth_hdr[80];
snprintf(auth_hdr, sizeof(auth_hdr), "Bearer %s", s_cfg.seed_token);
esp_http_client_set_header(client, "Authorization", auth_hdr);
}
```
**Impact:** Bearer token can be sniffed on the local network, enabling unauthorized access to the Cognitum Seed ingest API.
**Remediation:**
1. Validate that `seed_url` starts with `https://` in `swarm_bridge_init()` and reject `http://` URLs.
2. Configure TLS certificate verification in the HTTP client config.
3. Consider certificate pinning for the Seed server.
---
### MEDIUM-007: In-Memory Rate Limiter Does Not Bound Memory Growth (CWE-400)
**Severity:** MEDIUM
**OWASP:** A04:2021 -- Insecure Design
**Files:**
- `archive/v1/src/api/middleware/rate_limit.py:28-29` -- `self.request_counts = defaultdict(lambda: deque())`
- `archive/v1/src/middleware/rate_limit.py:132` -- `self._sliding_windows: Dict[str, SlidingWindowCounter] = {}`
**Description:**
Both rate limiter implementations store per-client sliding window data in unbounded in-memory dictionaries. An attacker sending requests from many spoofed IPs (see HIGH-002) can create millions of entries, each containing a `deque` of timestamps. The cleanup tasks run only periodically (every 5 minutes or on-demand) and cannot keep pace with a high-rate attack.
**Impact:** Memory exhaustion denial of service through rate limiter state amplification.
**Remediation:**
1. Cap the total number of tracked clients (e.g., 100,000 entries). Use an LRU eviction policy.
2. Use a fixed-size data structure (e.g., a counter array with hash bucketing) instead of per-client deques.
3. For production, use Redis-backed rate limiting with automatic key expiry.
---
### LOW-001: Test Script Contains Hardcoded Placeholder Secret (CWE-798)
**Severity:** LOW
**OWASP:** A07:2021 -- Identification and Authentication Failures
**File:** `v1/test_auth_rate_limit.py:26`
**Description:**
A test script in the repository contains a hardcoded JWT secret key placeholder:
```python
SECRET_KEY = "your-secret-key-here" # This should match your settings
```
While marked with a comment indicating it should be changed, this file is checked into the repository and could be mistaken for a real configuration.
**Impact:** Low -- this is a test file, not production configuration. However, if a developer copies this value into production settings, JWT tokens become trivially forgeable.
**Remediation:**
1. Replace with an environment variable reference: `SECRET_KEY = os.environ.get("SECRET_KEY", "")`.
2. Add a validation check that fails if the secret is the placeholder value.
---
### LOW-002: User Information Exposed in Response Headers (CWE-200)
**Severity:** LOW
**OWASP:** A01:2021 -- Broken Access Control
**Files:**
- `archive/v1/src/middleware/auth.py:298-299` -- `response.headers["X-User"] = user_info["username"]` and `response.headers["X-User-Roles"] = ",".join(user_info["roles"])`
- `archive/v1/src/api/middleware/auth.py:111` -- `response.headers["X-User-ID"] = request.state.user.get("id", "")`
**Description:**
Authenticated user information (username, roles, user ID) is included in HTTP response headers. These headers are visible to any intermediary (CDN, reverse proxy, browser extensions) and in browser developer tools.
**Impact:** Information disclosure of user identity and authorization roles to intermediaries and client-side code.
**Remediation:**
1. Remove `X-User`, `X-User-Roles`, and `X-User-ID` response headers, or restrict them to internal/debug environments only.
2. If needed for debugging, use a configuration flag to enable these headers.
---
### LOW-003: Deprecated `datetime.utcnow()` Usage (CWE-1235)
**Severity:** LOW
**Files:** Throughout the Python codebase (auth.py, rate_limit.py, connection_manager.py, pose_stream.py, error_handler.py, stream.py)
**Description:**
`datetime.utcnow()` is deprecated in Python 3.12+ in favor of `datetime.now(datetime.timezone.utc)`. While not a security vulnerability per se, timezone-naive datetimes can cause token expiry comparison bugs in environments where the system clock timezone differs from UTC.
**Remediation:**
Replace all instances of `datetime.utcnow()` with `datetime.now(datetime.timezone.utc)`.
---
### LOW-004: JWT Algorithm Not Restricted to Asymmetric in Production (CWE-327)
**Severity:** LOW
**OWASP:** A02:2021 -- Cryptographic Failures
**File:** `archive/v1/src/config/settings.py:30` -- `jwt_algorithm: str = Field(default="HS256")`
**Description:**
The default JWT algorithm is HS256 (HMAC-SHA256), a symmetric algorithm. This means the same secret is used for both signing and verification, requiring the secret to be distributed to every service that needs to verify tokens. For multi-service architectures, asymmetric algorithms (RS256, ES256) are preferred.
Additionally, the `jwt_algorithm` setting is not validated against a safe algorithm allowlist, leaving open the possibility of configuration to `none` (no signature).
**Remediation:**
1. Validate `jwt_algorithm` against an allowlist of safe algorithms: `["HS256", "HS384", "HS512", "RS256", "RS384", "RS512", "ES256", "ES384", "ES512"]`.
2. Explicitly reject the `none` algorithm.
3. For production deployments with multiple services, recommend RS256 or ES256.
---
### LOW-005: No Password Complexity Validation (CWE-521)
**Severity:** LOW
**OWASP:** A07:2021 -- Identification and Authentication Failures
**File:** `archive/v1/src/middleware/auth.py:115` -- `create_user()` method
**Description:**
The `create_user()` method accepts any password without minimum length, complexity, or entropy requirements. Test credentials in `v1/test_auth_rate_limit.py:21-23` demonstrate weak passwords ("admin123", "user123").
**Remediation:**
1. Enforce minimum password length (12+ characters).
2. Check passwords against a common-password blocklist.
3. Require mixed character classes or calculate entropy.
---
### INFORMATIONAL-001: Rust API, DB, and Config Crates Are Stubs
**Files:**
- `v2/crates/wifi-densepose-api/src/lib.rs` -- `//! WiFi-DensePose REST API (stub)`
- `v2/crates/wifi-densepose-db/src/lib.rs` -- `//! WiFi-DensePose database layer (stub)`
- `v2/crates/wifi-densepose-config/src/lib.rs` -- `//! WiFi-DensePose configuration (stub)`
**Description:**
The Rust API, database, and configuration crates contain only single-line stub comments. No security review of Rust API endpoints, database queries, or configuration handling was possible because no implementation exists. The `wifi-densepose-sensing-server` crate contains the actual Rust server implementation.
**Note:** The sensing server (`crates/wifi-densepose-sensing-server/src/main.rs`) was checked for SQL injection patterns, CORS issues, and authentication concerns. No SQL injection risks were found (no string-formatted queries). The server appears to use in-memory data structures rather than a database.
---
### INFORMATIONAL-002: Rust `unsafe` Blocks in WASM Edge Crate
**Files:** `v2/crates/wifi-densepose-wasm-edge/src/*.rs` (multiple files)
**Description:**
The `wifi-densepose-wasm-edge` crate contains approximately 40 `unsafe` blocks, primarily for:
1. Writing to static mutable event arrays (`static mut EVENTS: [...]`)
2. Raw pointer casts for `repr(C)` struct serialization in `rvf.rs`
These patterns are common in `no_std` WASM edge environments where heap allocation is unavailable. The static event arrays use a fixed-size pattern (`EVENTS[..n]`) that prevents out-of-bounds writes as long as `n` is bounded correctly. Visual inspection of the bounds checks suggests they are correct, but formal verification or fuzzing of the bounds logic is recommended.
The main workspace crate (`wifi-densepose-train`) explicitly notes it avoids `unsafe` blocks.
---
### INFORMATIONAL-003: ESP32 Firmware C Code Uses Safe String Handling
**Files:** `firmware/esp32-csi-node/main/*.c`
**Description:**
The firmware codebase consistently uses `strncpy` with explicit null termination, `snprintf` (not `sprintf`), and proper bounds checking throughout. No instances of `strcpy`, `strcat`, `sprintf`, or `gets` were found. Buffer sizes are defined via `#define` constants. The `rvf_parser.c` performs thorough size validation before any pointer arithmetic.
This is a positive finding reflecting good security practices.
---
## Dependency Analysis
### Python Dependencies (`requirements.txt`)
| Package | Version Spec | Risk |
|---------|-------------|------|
| `python-jose[cryptography]>=3.3.0` | MEDIUM -- python-jose has had JWT confusion vulnerabilities. Consider migrating to `PyJWT` or `authlib`. |
| `paramiko>=3.0.0` | LOW -- SSH library. Ensure latest minor version for CVE patches. |
| `fastapi>=0.95.0` | LOW -- Version floor is old. Pin to latest stable for security patches. |
**Recommendation:** Run `pip audit` or `safety check` against the locked dependency file (`archive/v1/requirements-lock.txt`) to identify known CVEs.
### Rust Dependencies (`Cargo.toml`)
| Crate | Version | Notes |
|-------|---------|-------|
| `sqlx 0.7` | OK -- uses parameterized queries by design. |
| `axum 0.7` | OK -- current major version. |
| `wasm-bindgen 0.2` | OK -- standard WASM interface. |
**Recommendation:** Run `cargo audit` against `Cargo.lock` to check for known advisories.
---
## Positive Security Practices Observed
The following areas demonstrate security-conscious design:
1. **OTA PSK constant-time comparison** (`firmware/esp32-csi-node/main/ota_update.c:66-72`): Uses XOR-accumulator pattern to prevent timing attacks on authentication.
2. **WASM signature verification** (`firmware/esp32-csi-node/main/wasm_upload.c:112-137`): Ed25519 signature verification is enabled by default (`wasm_verify=1`). Unsigned uploads are rejected unless explicitly disabled via Kconfig.
3. **RVF build hash validation** (`firmware/esp32-csi-node/main/rvf_parser.c:126-137`): SHA-256 hash of the WASM payload is verified against the manifest before loading, preventing tampered module execution.
4. **Password hashing with bcrypt** (`archive/v1/src/middleware/auth.py:21`): Proper use of `passlib` with `bcrypt` scheme.
5. **Protected user fields** (`archive/v1/src/middleware/auth.py:139`): `update_user()` prevents modification of `username`, `created_at`, and `hashed_password`.
6. **Production error suppression** (`archive/v1/src/middleware/error_handler.py:214-218`): The centralized error handler correctly suppresses internal details in production mode.
7. **No hardcoded secrets in source** (verified via entropy-based search across entire repository): No API keys, passwords, or tokens found in source files (the test script placeholder at `test_auth_rate_limit.py:26` is marked as requiring replacement).
8. **`.env` file excluded via `.gitignore`** (`.gitignore:171`): Environment files are properly excluded from version control.
9. **C string safety** (all `firmware/esp32-csi-node/main/*.c`): Consistent use of `strncpy`, `snprintf`, and null-termination guards. No unsafe C string functions.
10. **NVS input validation** (`firmware/esp32-csi-node/main/nvs_config.c`): Bounds checking on all NVS-loaded values (channel range, dwell time minimums, array index clamping).

# Performance Analysis Report -- WiFi-DensePose
**Report ID**: QE-PERF-003
**Date**: 2026-04-05
**Analyst**: QE Performance Reviewer (V3, chaos-resilience domain)
**Scope**: Rust signal processing, NN inference, Python pipeline, ESP32 firmware
**Files Examined**: 32 source files across 4 codebases
**Weighted Finding Score**: 14.25 (minimum threshold: 2.0)
---
## Executive Summary
The WiFi-DensePose codebase is a real-time sensing system targeting 20 Hz output (50 ms budget per frame). The analysis identified **4 CRITICAL**, **6 HIGH**, **8 MEDIUM**, and **5 LOW** performance findings across Rust signal processing, neural network inference, Python pipeline, and ESP32 firmware. The most impactful issues are: (1) an O(n*K*S) top-K selection in the ESP32 firmware hot path, (2) O(L * V) tomographic weight computation on every frame, (3) serial batch inference in the NN crate, and (4) excessive heap allocation in the Python CSI pipeline's Doppler extraction. Estimated combined latency savings from addressing CRITICAL and HIGH findings: 15-40 ms per frame (30-80% of the 50 ms budget).

### FINDING PERF-R01: Tomography Weight Matrix -- O(L * nx * ny * nz) per Link [CRITICAL]
**File**: `v2/crates/wifi-densepose-signal/src/ruvsense/tomography.rs`
**Lines**: 345-383 (`compute_link_weights`)
The `compute_link_weights` function iterates over every voxel in the grid for every link to compute Fresnel-zone intersection weights:
```rust
for iz in 0..config.nz {
for iy in 0..config.ny {
for ix in 0..config.nx {
// point_to_segment_distance per voxel
let dist = point_to_segment_distance(...);
if dist < fresnel_radius {
weights.push((idx, w));
}
}
}
}
```
**Impact**: With default grid 8x8x4 = 256 voxels and 12 links, this is 3,072 distance calculations at construction time. However, if the grid is scaled to 16x16x8 = 2,048 voxels with 24 links, this becomes 49,152 calculations. Each involves a sqrt() and 6 multiplications.
**Impact on ISTA Solver (lines 264-307)**: The reconstruct() method runs up to 100 iterations, each computing O(L * average_weights_per_link) for forward pass and the same for gradient accumulation. With dense weight matrices, this dominates the frame budget.
**Severity**: CRITICAL -- Blocks real-time operation at higher grid resolutions.
**Recommendation**:
1. Use Bresenham-style ray marching (3D DDA) instead of brute-force voxel scan -- reduces from O(V) to O(max(nx,ny,nz)) per link.
2. Precompute weight matrix once, store as CSR sparse format for cache-friendly iteration.
3. Use FISTA (Fast ISTA) with Nesterov momentum for 2-3x faster convergence.
**Estimated Savings**: 5-10x for weight computation, 2-3x for solver convergence.
---
### FINDING PERF-R02: Multistatic Fusion -- sin()/cos() per Subcarrier per Node [HIGH]
**File**: `v2/crates/wifi-densepose-signal/src/ruvsense/multistatic.rs`
**Lines**: 287-298 (`attention_weighted_fusion`)
```rust
for (n, (&amp, &ph)) in amplitudes.iter().zip(phases.iter()).enumerate() {
let w = weights[n];
for i in 0..n_sub {
fused_amp[i] += w * amp[i];
fused_ph_sin[i] += w * ph[i].sin(); // transcendental per element
fused_ph_cos[i] += w * ph[i].cos(); // transcendental per element
}
}
```
**Impact**: With N=4 nodes and S=56 subcarriers, this is 448 sin() + 448 cos() = 896 transcendental function calls per frame at 20 Hz = 17,920/sec. On typical hardware, each sin/cos takes ~20ns, totaling ~18 us/frame. Not blocking by itself, but avoidable.
**Severity**: HIGH -- Unnecessary CPU in hot path.
**Recommendation**:
1. Use `sincos()` or `(ph.sin(), ph.cos())` as a single call where the compiler can fuse.
2. Pre-compute sin/cos of phase vectors before the fusion loop using SIMD (via `packed_simd` or `std::simd`).
3. Alternative: Store phase as phasor (sin, cos) pairs throughout the pipeline, avoiding conversion entirely.
**Estimated Savings**: 2-3x for phase fusion, eliminates transcendental calls.
---
### FINDING PERF-R03: Pose Tracker find_track -- Linear Search [MEDIUM]
**File**: `v2/crates/wifi-densepose-signal/src/ruvsense/pose_tracker.rs`
**Lines**: 546-553
```rust
pub fn find_track(&self, id: TrackId) -> Option<&PoseTrack> {
self.tracks.iter().find(|t| t.id == id)
}
```
**Impact**: Linear O(T) search for each track lookup. With T <= 10 tracks in typical usage, this is negligible. However, `active_tracks()` and `active_count()` also do full scans with `filter()`.
**Severity**: MEDIUM -- Low impact at current scale, but would degrade with many tracks.
**Recommendation**: Use a `HashMap<TrackId, usize>` index for O(1) lookup if track count grows beyond 20.
---
### FINDING PERF-R04: Multistatic FusedSensingFrame -- Deep Clone of node_frames [HIGH]
**File**: `v2/crates/wifi-densepose-signal/src/ruvsense/multistatic.rs`
**Line**: 222
```rust
Ok(FusedSensingFrame {
...
node_frames: node_frames.to_vec(), // deep clone of all MultiBandCsiFrame structs
...
})
```
**Impact**: Each `MultiBandCsiFrame` contains `Vec<CanonicalCsiFrame>` with amplitude and phase vectors. With N=4 nodes, each containing 3 channels of 56 subcarriers, this clones 4 * 3 * 56 * 2 * 4 bytes = 5,376 bytes of float data plus Vec heap allocations. At 20 Hz = 107 KB/s of unnecessary heap churn.
**Severity**: HIGH -- Unnecessary allocation in the hottest path.
**Recommendation**:
1. Accept `Vec<MultiBandCsiFrame>` by move instead of borrowing then cloning.
2. Alternatively, use `Arc<[MultiBandCsiFrame]>` for zero-copy sharing.
3. Use a pre-allocated buffer pool with frame recycling.
**Estimated Savings**: Eliminates ~5 KB allocation + copy per frame.

### FINDING PERF-R05: Coherence Score -- Efficient but exp() in Hot Loop [LOW]
**File**: `v2/crates/wifi-densepose-signal/src/ruvsense/coherence.rs`
**Lines**: 224-252 (`coherence_score`)
```rust
for i in 0..n {
let var = variance[i].max(epsilon);
let z = (current[i] - reference[i]).abs() / var.sqrt();
let weight = 1.0 / (var + epsilon);
let likelihood = (-0.5 * z * z).exp(); // exp() per subcarrier
weighted_sum += likelihood * weight;
weight_sum += weight;
}
```
**Impact**: 56 exp() calls per frame at 20 Hz = 1,120/sec. Each exp() ~10ns = ~11 us total. Additionally, sqrt() per iteration.
**Severity**: LOW -- Under 15 us total, within budget.
**Recommendation**: Use fast_exp approximation or lookup table for the Gaussian kernel if profiling shows this as a bottleneck. Could also batch with SIMD.
---
### FINDING PERF-R06: Gesture DTW -- O(N * M) per Template [MEDIUM]
**File**: `v2/crates/wifi-densepose-signal/src/ruvsense/gesture.rs`
**Lines**: 288-328 (`dtw_distance`)
The DTW implementation uses the Sakoe-Chiba band constraint (good), but allocates two full Vec<f64> per call:
```rust
let mut prev = vec![f64::INFINITY; m + 1]; // heap allocation
let mut curr = vec![f64::INFINITY; m + 1]; // heap allocation
```
With T templates and band_width=5, complexity is O(T * N * band_width * feature_dim). The feature_dim inner loop (euclidean_distance) is also not vectorized.
**Impact**: For 5 templates, 20 frames, 8 features, band_width=5: 5 * 20 * 5 * 8 = 4,000 operations per classification. Acceptable for on-demand use but costly if called every frame.
**Severity**: MEDIUM -- Acceptable for on-demand, but allocation should be eliminated.
**Recommendation**:
1. Pre-allocate DTW scratch buffers in the GestureClassifier struct.
2. Use SmallVec or stack arrays for typical sequence lengths.
3. Consider early termination: if partial DTW cost exceeds current best, abort.
---
### FINDING PERF-R07: Field Model Covariance -- O(S^2) Memory [MEDIUM]
**File**: `v2/crates/wifi-densepose-signal/src/ruvsense/field_model.rs`
**Line**: 330 (`covariance_sum: Option<Array2<f64>>`)
The full covariance matrix for SVD is S x S where S = number of subcarriers. With S=56, this is 56 * 56 * 8 = 25 KB -- reasonable. But the diagonal_fallback (lines 338-383) creates unnecessary intermediate allocations.
**Severity**: MEDIUM -- Calibration-phase only, but the fallback path allocates on every call.
**Recommendation**: Pre-allocate the indices vector in the struct to avoid repeated allocation during fallback.
---
### FINDING PERF-R08: Multiband Duplicate Frequency Check -- O(N^2) [LOW]
**File**: `v2/crates/wifi-densepose-signal/src/ruvsense/multiband.rs`
**Lines**: 126-135
```rust
for i in 0..self.frequencies.len() {
for j in (i + 1)..self.frequencies.len() {
if self.frequencies[i] == self.frequencies[j] {
return Err(...);
}
}
}
```
**Impact**: With N=3 channels, this is 3 comparisons. Negligible.
**Severity**: LOW -- N is tiny (3-6 channels max).
**Recommendation**: No action needed at current scale. If N grows, use a HashSet.
---
### FINDING PERF-R09: Adversarial Detector -- Potential O(L^2) Consistency Check [MEDIUM]
**File**: `v2/crates/wifi-densepose-signal/src/ruvsense/adversarial.rs`
**Lines**: 147+
The multi-link consistency check compares energy ratios across all links. With L=12 links, the pairwise comparison (if implemented) would be O(L^2) = 144. Combined with the four independent checks (consistency, field model, temporal, energy), this runs on every frame.
**Severity**: MEDIUM -- O(L^2) with L=12 is acceptable, but should be monitored if link count grows.
**Recommendation**: Document maximum supported link count. Consider using pre-sorted energy lists for O(L log L) consistency checking.

## 2. Rust Neural Network Inference
### Files Analyzed
| File | Lines | Role |

| `wifi-densepose-nn/src/tensor.rs` | 100+ | Tensor abstraction |

### FINDING PERF-NN01: Serial Batch Inference [CRITICAL]
**File**: `v2/crates/wifi-densepose-nn/src/inference.rs`
**Lines**: 334-336
```rust
pub fn infer_batch(&self, inputs: &[Tensor]) -> NnResult<Vec<Tensor>> {
inputs.iter().map(|input| self.infer(input)).collect()
}
```
**Impact**: Batch inference is implemented as sequential single-input calls. This completely negates GPU batching benefits and prevents ONNX Runtime from parallelizing across batch dimensions. For batch_size=4, this is 4x the latency of a properly batched inference.
**Severity**: CRITICAL -- Defeats the purpose of batch inference.
**Recommendation**:
1. Concatenate inputs along batch dimension into a single tensor.
2. Run a single backend.run() call with the batched tensor.
3. Split output tensor back into individual results.
**Estimated Savings**: 2-4x latency reduction for batched inference.
---
### FINDING PERF-NN02: Async Stats Update Spawns Tokio Task per Inference [HIGH]
**File**: `v2/crates/wifi-densepose-nn/src/inference.rs`
**Lines**: 311-315
```rust
let stats = self.stats.clone();
tokio::spawn(async move {
let mut stats = stats.write().await;
stats.record(elapsed_ms);
});
```
**Impact**: Every single inference call spawns a new Tokio task just to record timing statistics. At 20 Hz inference rate, this creates 20 tasks/second, each acquiring an RwLock write guard. The task creation overhead (~1-5 us) and lock contention are unnecessary.
**Severity**: HIGH -- Unnecessary async overhead in synchronous hot path.
**Recommendation**:
1. Use `AtomicU64` for total count and `AtomicF64` (or a lock-free accumulator) for timing.
2. Alternatively, use `try_write()` and skip stats update if lock is contended.
3. Best: Use a thread-local accumulator with periodic flush.
---
### FINDING PERF-NN03: Tensor Clone in run_single [MEDIUM]
**File**: `v2/crates/wifi-densepose-nn/src/inference.rs`
**Lines**: 122
```rust
fn run_single(&self, input: &Tensor) -> NnResult<Tensor> {
let mut inputs = HashMap::new();
inputs.insert(input_names[0].clone(), input.clone()); // full tensor clone
```
**Impact**: The default `run_single` implementation clones the entire input tensor to put it into a HashMap. For a [1, 256, 64, 64] tensor of f32, that is 4 MB of data copied unnecessarily.
**Severity**: MEDIUM -- 4 MB copy at 20 Hz = 80 MB/s of unnecessary bandwidth.
**Recommendation**: Accept input by value (move semantics) or use a reference-counted tensor.
---
### FINDING PERF-NN04: WiFiDensePosePipeline -- Two Sequential Inferences [MEDIUM]
**File**: `v2/crates/wifi-densepose-nn/src/inference.rs`
**Lines**: 389-413
```rust
pub fn run(&self, csi_input: &Tensor) -> NnResult<DensePoseOutput> {
let visual_features = self.translator_backend.run_single(csi_input)?;
let outputs = self.densepose_backend.run(inputs)?;
```
**Impact**: The pipeline runs two separate inference calls sequentially: CSI-to-visual translator, then DensePose head. If each takes 10-15 ms, total is 20-30 ms -- consuming 40-60% of the 50 ms frame budget on inference alone.
**Severity**: MEDIUM -- Architectural constraint, but pipelining is possible.
**Recommendation**:
1. Implement pipeline parallelism: while frame N's DensePose runs, start frame N+1's translator.
2. Consider fusing the two models into a single ONNX graph for optimized execution.
3. Profile to determine actual bottleneck -- translator or DensePose head.

## 3. Python Real-Time Pipeline

### FINDING PERF-PY01: Doppler Feature Extraction -- list() Conversion of deque [CRITICAL]
**File**: `archive/v1/src/core/csi_processor.py`
**Lines**: 412-414
```python
cache_list = list(self._phase_cache) # O(n) copy of entire deque
phase_matrix = np.array(cache_list[-window:]) # another copy
```
**Impact**: Every frame converts the entire phase_cache deque (up to 500 entries) to a list, then slices and converts to numpy. With 500 entries of 56-element arrays, this copies ~112 KB per frame. At 20 Hz, that is 2.2 MB/s of unnecessary Python object creation and GC pressure.
**Severity**: CRITICAL -- Major allocation in the hot path.
**Recommendation**:
1. Use a pre-allocated numpy circular buffer instead of a deque of arrays.
2. Maintain a write pointer and wrap around, avoiding all list/deque conversions.
3. Implementation sketch:
```python
class CircularBuffer:
def __init__(self, max_len, feature_dim):
self.buf = np.zeros((max_len, feature_dim), dtype=np.float32)
self.idx = 0
self.count = 0
```
**Estimated Savings**: Eliminates ~112 KB allocation per frame, reduces GC pressure by >90%.
---
### FINDING PERF-PY02: CSI Preprocessing Creates 3 New CSIData Objects per Frame [HIGH]
**File**: `archive/v1/src/core/csi_processor.py`
**Lines**: 118-377
The preprocessing pipeline creates a new CSIData object at each step:
```python
cleaned_data = self._remove_noise(csi_data) # new CSIData + dict merge
windowed_data = self._apply_windowing(cleaned_data) # new CSIData + dict merge
normalized_data = self._normalize_amplitude(windowed_data) # new CSIData + dict merge
```
Each CSIData construction copies metadata via `{**csi_data.metadata, 'key': True}`, creating a new dict each time.
**Impact**: 3 CSIData allocations + 3 dict merges + 3 numpy array operations per frame. The dict merges create O(n) copies of the metadata dictionary each time.
**Severity**: HIGH -- Unnecessary object churn in hot path.
**Recommendation**:
1. Mutate arrays in-place instead of creating new CSIData objects.
2. Use a mutable processing context that carries arrays through the pipeline.
3. Accumulate metadata flags in a separate lightweight structure.
---
### FINDING PERF-PY03: Correlation Matrix -- Full np.corrcoef on Every Frame [MEDIUM]
**File**: `archive/v1/src/core/csi_processor.py`
**Lines**: 391-395
```python
def _extract_correlation_features(self, csi_data: CSIData) -> np.ndarray:
correlation_matrix = np.corrcoef(csi_data.amplitude)
return correlation_matrix
```
**Impact**: `np.corrcoef` computes the full NxN correlation matrix where N = number of antennas (typically 3). For 3x3, this is fast. However, if amplitude has shape (num_antennas, num_subcarriers) = (3, 56), corrcoef computes 3x3 matrix -- acceptable. But if amplitude is (56, 3) or another shape, this could produce a 56x56 matrix, which involves O(56^2 * 3) = 9,408 operations per frame.
**Severity**: MEDIUM -- Depends on actual amplitude shape; could be 100x more expensive than expected.
**Recommendation**: Validate and document the expected shape. If only antenna-pair correlations are needed, compute them directly without the full matrix.
---
### FINDING PERF-PY04: WebSocket Broadcast -- Sequential Send to All Clients [MEDIUM]
**File**: `archive/v1/src/api/websocket/connection_manager.py`
**Lines**: 230-264
```python
async def broadcast(self, data, stream_type=None, zone_ids=None, **filters):
for client_id in matching_clients:
success = await self.send_to_client(client_id, data) # sequential await
```
**Impact**: Each WebSocket send is awaited sequentially. With 10 connected clients and ~1 ms per send, broadcast takes ~10 ms per frame -- 20% of the frame budget spent on I/O serialization.
**Severity**: MEDIUM -- Scales linearly with client count.
**Recommendation**: Use `asyncio.gather()` to send to all clients concurrently:
```python
tasks = [self.send_to_client(cid, data) for cid in matching_clients]
results = await asyncio.gather(*tasks, return_exceptions=True)
```
**Estimated Savings**: Reduces broadcast from O(N * latency) to O(latency).
---
### FINDING PERF-PY05: get_recent_history -- Copies Entire History [LOW]
**File**: `archive/v1/src/core/csi_processor.py`
**Lines**: 284-297
```python
def get_recent_history(self, count: int) -> List[CSIData]:
if count >= len(self.csi_history):
return list(self.csi_history) # full copy
else:
return list(self.csi_history)[-count:] # full copy then slice
```
**Impact**: Both branches create a full list copy of the deque before potentially slicing. With 500 entries, this creates a list of 500 references unnecessarily.
**Severity**: LOW -- Only called on-demand, not in hot path.
**Recommendation**: Use `itertools.islice` for the windowed case, or index directly into the deque.
---
## 4. ESP32 Firmware
### Files Analyzed
| File | Lines | Role |
|------|-------|------|
| `firmware/esp32-csi-node/main/csi_collector.c` | 421 | CSI callback + channel hopping |
| `firmware/esp32-csi-node/main/edge_processing.c` | 1000+ | On-device DSP pipeline |

### FINDING PERF-FW01: Top-K Subcarrier Selection -- O(K * S) with K=8, S=128 [HIGH]
**File**: `firmware/esp32-csi-node/main/edge_processing.c`
**Lines**: 301-330 (`update_top_k`)
```c
for (uint8_t ki = 0; ki < k; ki++) {
double best_var = -1.0;
uint8_t best_idx = 0;
for (uint16_t sc = 0; sc < n_subcarriers; sc++) {
if (!used[sc]) {
double v = welford_variance(&s_subcarrier_var[sc]);
if (v > best_var) {
best_var = v;
best_idx = (uint8_t)sc;
}
}
}
s_top_k[ki] = best_idx;
used[best_idx] = true;
}
```
**Impact**: Runs K=8 passes over S=128 subcarriers = 1,024 iterations with `welford_variance()` call each (2 divisions). On ESP32-S3 at 240 MHz with no FPU for doubles, each division takes ~50 cycles, totaling ~102,400 cycles = ~427 us per call. This runs on every frame at 20 Hz.
**Severity**: HIGH -- 427 us is nearly 1% of the 50 ms frame budget, and double-precision division on ESP32 is expensive.
**Recommendation**:
1. Use `float` instead of `double` for variance -- ESP32-S3 has single-precision FPU.
2. Pre-compute variances into a float array, then find top-K with a single partial sort.
3. Use `nth_element`-style partial sort (O(S + K log K) instead of O(K * S)).
4. Cache variance values and only recompute when Welford count changes.
**Estimated Savings**: 5-10x by switching to float + partial sort.
---
### FINDING PERF-FW02: Static Memory Layout -- Large BSS Usage [MEDIUM]
**File**: `firmware/esp32-csi-node/main/edge_processing.c`
**Lines**: 224-287
The module declares substantial static arrays:
| Variable | Size | Notes |
|----------|------|-------|
| `s_subcarrier_var[128]` | 128 * 24 = 3,072 bytes | Welford structs (mean, m2, count) |
| `s_prev_phase[128]` | 512 bytes | float array |
| `s_phase_history[256]` | 1,024 bytes | float array |
| `s_breathing_filtered[256]` | 1,024 bytes | float array |
| `s_heartrate_filtered[256]` | 1,024 bytes | float array |
| `s_scratch_br[256]` | 1,024 bytes | float array |
| `s_scratch_hr[256]` | 1,024 bytes | float array |
| `s_prev_iq[1024]` | 1,024 bytes | delta compression |
| `s_person_br_filt[4][256]` | 4,096 bytes | per-person BR filter |
| `s_person_hr_filt[4][256]` | 4,096 bytes | per-person HR filter |
| Ring buffer (16 slots * 1024+) | ~17 KB | SPSC ring |
| **Total BSS** | **~34 KB** | |
**Impact**: ESP32-S3 has 512 KB SRAM. This module alone uses ~34 KB (6.6%). Combined with WiFi stack (~50 KB), FreeRTOS (~20 KB), and other modules, total RAM usage may approach limits on 4MB flash variants.
**Severity**: MEDIUM -- Acceptable on 8MB variant, may be tight on 4MB SuperMini.
**Recommendation**:
1. Reduce `EDGE_PHASE_HISTORY_LEN` from 256 to 128 on 4MB builds (saves ~6 KB).
2. Consider using `EDGE_MAX_PERSONS=2` on constrained builds (saves ~4 KB).
3. Add build-time assertion for total BSS usage.
---
### FINDING PERF-FW03: CSI Callback Rate Limiting -- Correct but Coarse [LOW]
**File**: `firmware/esp32-csi-node/main/csi_collector.c`
**Lines**: 177-195
```c
int64_t now = esp_timer_get_time();
if ((now - s_last_send_us) >= CSI_MIN_SEND_INTERVAL_US) {
int ret = stream_sender_send(frame_buf, frame_len);
```
**Impact**: Rate limiting at 50 Hz (20 ms interval) is correct. The `memcpy` at line 175 (`csi_serialize_frame`) runs on every callback even if the frame will be rate-skipped. With callbacks firing at 100-500 Hz in promiscuous mode, this wastes 80-90% of serialization effort.
**Severity**: LOW -- memcpy of ~300 bytes is ~1 us, acceptable.
**Recommendation**: Move rate limit check before serialization to skip unnecessary work:
```c
int64_t now = esp_timer_get_time();
if ((now - s_last_send_us) < CSI_MIN_SEND_INTERVAL_US) {
s_rate_skip++;
return; // skip serialization entirely
}
```
---
### FINDING PERF-FW04: atan2f() per Subcarrier in Phase Extraction [LOW]
**File**: `firmware/esp32-csi-node/main/edge_processing.c`
**Lines**: 134-139
```c
static inline float extract_phase(const uint8_t *iq, uint16_t idx)
{
int8_t i_val = (int8_t)iq[idx * 2];
int8_t q_val = (int8_t)iq[idx * 2 + 1];
return atan2f((float)q_val, (float)i_val);
}
```
**Impact**: Called for each subcarrier (up to 128) per frame. atan2f on ESP32-S3 takes ~100 cycles with FPU = ~0.4 us per call. 128 calls = ~51 us per frame. Acceptable.
**Severity**: LOW -- Within budget.
**Recommendation**: If profiling reveals this as a bottleneck, use a CORDIC-based atan2 approximation (10-20 cycles instead of 100).
---
### FINDING PERF-FW05: Lock-Free Ring Buffer -- Correct but Not Power-of-2 [LOW]
**File**: `firmware/esp32-csi-node/main/edge_processing.c`
**Lines**: 55-56
```c
uint32_t next = (s_ring.head + 1) % EDGE_RING_SLOTS;
```
`EDGE_RING_SLOTS = 16` which IS a power of 2 (good), but the code uses `%` instead of `& (EDGE_RING_SLOTS - 1)`. The compiler should optimize this for power-of-2 constants, but it is not guaranteed on all optimization levels.
**Severity**: LOW -- Compiler likely optimizes this.
**Recommendation**: Use explicit bitmask for clarity and guaranteed optimization:
```c
uint32_t next = (s_ring.head + 1) & (EDGE_RING_SLOTS - 1);
```
---
## 5. Cross-Cutting Concerns
### FINDING PERF-XC01: Missing Parallelism in Multistatic Pipeline [HIGH]
**File**: `v2/crates/wifi-densepose-signal/src/ruvsense/mod.rs`
**Lines**: 183-232
The `RuvSensePipeline` orchestrator processes stages sequentially. The multiband fusion and phase alignment stages for each node are independent and could run in parallel using Rayon:
```
Node 0: multiband -> phase_align \
Node 1: multiband -> phase_align }-> multistatic fusion -> coherence -> gate
Node 2: multiband -> phase_align /
Node 3: multiband -> phase_align /
```
**Impact**: With 4 nodes, sequential processing takes 4x the single-node latency. Parallelization could reduce this to 1x (assuming available cores).
**Severity**: HIGH -- Linear scaling with node count in time-critical path.
**Recommendation**: Use `rayon::par_iter` for per-node multiband + phase_align stages. Only the multistatic fusion (which requires all nodes) remains sequential.
---
### FINDING PERF-XC02: No Pre-allocated Buffer Pool [MEDIUM]
Across the Rust codebase, many functions allocate fresh Vec<> for intermediate results that are immediately consumed and dropped. Examples:
- `multistatic.rs` line 249: `let mut mean_amp = vec![0.0_f32; n_sub];`
- `multistatic.rs` line 287-289: 3 Vecs for fusion output
- `tomography.rs` line 246: `let mut x = vec![0.0_f64; self.n_voxels];`
- `tomography.rs` line 266: `let mut gradient = vec![0.0_f64; self.n_voxels];` (per iteration!)
- `gesture.rs` line 297-298: 2 Vecs per DTW call
**Impact**: Repeated allocation/deallocation causes allocator pressure and potential cache pollution. The gradient vector in tomography is allocated 100 times (once per ISTA iteration).
**Severity**: MEDIUM -- Cumulative impact on latency and GC pressure.
**Recommendation**:
1. Pre-allocate scratch buffers in the parent struct.
2. Use `Vec::clear()` + `Vec::resize()` instead of `vec![]` to reuse capacity.
3. For the ISTA gradient, allocate once outside the loop.

## 6. Performance Budget Analysis
### 50 ms Frame Budget Breakdown (20 Hz target)
| Stage | Current Est. | Optimized Est. | Finding |
|-------|-------------|----------------|---------|
| CSI Callback + Serialize | 1 ms | 0.5 ms | FW03 |
| Multiband Fusion (4 nodes) | 2 ms | 0.5 ms | XC01 |
| Phase Alignment | 1 ms | 1 ms | OK |
| Multistatic Fusion | 3 ms | 1 ms | R02, R04 |
| Coherence Scoring | 0.5 ms | 0.5 ms | R05 (OK) |
| Coherence Gating | <0.1 ms | <0.1 ms | OK |
| NN Translator Inference | 10-15 ms | 10-15 ms | NN04 |
| NN DensePose Inference | 10-15 ms | 10-15 ms | NN04 |
| Pose Tracking Update | 1 ms | 1 ms | R03 (OK) |
| Adversarial Check | 0.5 ms | 0.5 ms | R09 (OK) |
| WebSocket Broadcast | 5-10 ms | 1 ms | PY04 |
| Python Doppler Extraction | 3-5 ms | 0.5 ms | PY01 |
| **Total** | **37.5-54 ms** | **26.5-41 ms** | |
### Verdict
Current total is **borderline** -- the system may exceed the 50 ms budget under load with 4+ nodes and 10+ WebSocket clients. After applying the CRITICAL and HIGH recommendations, the budget drops to **26.5-41 ms**, providing 9-23 ms of headroom.

## 8. Patterns Checked (Clean Justification)
The following patterns were checked and found to be well-implemented:
| Pattern | Files Checked | Status |
|---------|--------------|--------|
| Unbounded buffers | csi_processor.py, edge_processing.c | CLEAN -- deque maxlen, ring buffer bounded |
| Lock contention | connection_manager.py, inference.rs | MINOR -- RwLock in NN stats (noted in NN02) |
| Blocking in async | pose_service.py, connection_manager.py | CLEAN -- all I/O properly awaited |
| Data structure choice | pose_tracker.rs, coherence.rs | CLEAN -- appropriate for current scale |
| Memory safety (ESP32) | edge_processing.c | CLEAN -- bounds checks, copy_len clamped |
| CSI rate limiting | csi_collector.c | CLEAN -- 20ms interval, well-documented |
| Phase unwrapping | edge_processing.c, phase_align.rs | CLEAN -- correct 2*pi wrap handling |
| Welford stability | field_model.rs, edge_processing.c | CLEAN -- numerically stable f64 accumulation |
| SPSC ring correctness | edge_processing.c | CLEAN -- memory barriers, single-producer |
| Kalman covariance | pose_tracker.rs | CLEAN -- diagonal approximation appropriate |

# Test Suite Analysis Report
**Project:** wifi-densepose (ruview)
**Date:** 2026-04-05
**Analyst:** QE Test Architect (V3)
**Scope:** All test suites across Python (v1), Rust (v2), and Mobile (ui/mobile)
---
## Executive Summary
The wifi-densepose project contains **3,353 total test functions** across three technology stacks:
| Stack | Test Functions | Files | Frameworks |
|-------|---------------|-------|------------|
| Rust (inline + integration) | 2,658 | 292 source files + 16 integration test files | `#[test]`, Rust built-in |
| Python (archive/v1/tests/) | 491 | 30 test files | pytest, pytest-asyncio |
| Mobile (ui/mobile) | 204 | 25 test files | Jest, React Testing Library |
| **Total** | **3,353** | **363** | |
### Overall Quality Score: 6.5/10
**Strengths:** Comprehensive Rust coverage, strong domain-specific signal processing validation, well-structured Python TDD suites.
**Critical Weaknesses:** Massive test duplication in Python CSI extractor tests, over-reliance on mocks in integration tests, several E2E/performance tests use mock objects that defeat the testing purpose, and mobile tests are predominantly smoke tests with shallow assertions.
---
## 1. Python Test Suite Analysis (archive/v1/tests/)
### 1.1 Test Distribution
| Category | Files | Test Functions | % of Total |
|----------|-------|---------------|------------|
| Unit | 14 | 325 | 66.2% |
| Integration | 11 | 109 | 22.2% |
| Performance | 2 | 26 | 5.3% |
| E2E | 1 | 8 | 1.6% |
| Fixtures/Mocks | 3 | 23 (helpers) | 4.7% |
| **Total** | **31** | **491** | **100%** |
**Pyramid Assessment:** 66:22:7 (unit:integration:e2e+perf) -- Slightly integration-light but within acceptable bounds.
### 1.2 Critical Finding: Massive Test Duplication
The CSI extractor module has **five** test files testing nearly identical functionality:
1. `test_csi_extractor.py` -- 16 tests (original, older API)
2. `test_csi_extractor_tdd.py` -- 18 tests (TDD rewrite)
3. `test_csi_extractor_tdd_complete.py` -- 20 tests (expanded TDD)
4. `test_csi_extractor_direct.py` -- 38 tests (direct imports)
5. `test_csi_standalone.py` -- 40 tests (standalone with importlib)
**Total: 132 tests across 5 files for a single module.**
These files test the same validation logic repeatedly. For example, the "empty amplitude" validation test appears in 4 of the 5 files with nearly identical code:
- `test_csi_extractor_tdd_complete.py:171-188` -- `test_validation_empty_amplitude`
- `test_csi_extractor_direct.py:293-310` -- `test_validation_empty_amplitude`
- `test_csi_standalone.py:305-322` -- `test_validate_empty_amplitude`
- `test_csi_extractor_tdd.py:166-181` -- `test_should_reject_invalid_csi_data`
The same pattern repeats for empty phase, invalid frequency, invalid bandwidth, invalid subcarriers, invalid antennas, SNR too low, and SNR too high -- each duplicated 3-4 times.
**Impact:** ~90 redundant tests. This inflates the test count by approximately 18% and creates a maintenance burden where changes to the CSI extractor require updating 4-5 test files.
**Recommendation:** Consolidate to a single test file (`test_csi_extractor.py`) using the `test_csi_standalone.py` approach (importlib-based, most comprehensive). Delete the other four files.
Similarly, there are duplicate suites for:
- Phase sanitizer: `test_phase_sanitizer.py` (7 tests) + `test_phase_sanitizer_tdd.py` (31 tests)
- Router interface: `test_router_interface.py` (13 tests) + `test_router_interface_tdd.py` (23 tests)
- CSI processor: `test_csi_processor.py` (6 tests) + `test_csi_processor_tdd.py` (25 tests)
### 1.3 Test Naming Conventions
Two competing conventions are used:
**Convention A (older tests):** `test_<action>_<condition>` (imperative)
```python
# test_csi_extractor.py:46
def test_extractor_initialization_creates_correct_configuration(self, ...):
```
**Convention B (TDD tests):** `test_should_<behavior>` (BDD-style)
```python
# test_csi_extractor_tdd.py:64
def test_should_initialize_with_valid_config(self, ...):
```
**Assessment:** Convention B is more descriptive and follows London School TDD naming. The project should standardize on one convention. Convention A is used in 6 files; Convention B in 8 files.
### 1.4 AAA Pattern Adherence
**Good examples:**
`test_csi_extractor.py:62-74` follows AAA with explicit comments:
```python
def test_start_extraction_configures_monitor_mode(self, ...):
# Arrange
mock_router_interface.enable_monitor_mode.return_value = True
# Act
result = csi_extractor.start_extraction()
# Assert
assert result is True
```
`test_sensing.py` follows AAA implicitly without comments but with clean structure throughout all 45 tests. This file is the best-written test file in the Python suite.
**Poor examples:**
`test_csi_processor_tdd.py:168-182` mixes arrangement with assertion:
```python
def test_should_preprocess_csi_data_successfully(self, csi_processor, sample_csi_data):
with patch.object(csi_processor, '_remove_noise') as mock_noise:
with patch.object(csi_processor, '_apply_windowing') as mock_window:
with patch.object(csi_processor, '_normalize_amplitude') as mock_normalize:
mock_noise.return_value = sample_csi_data
mock_window.return_value = sample_csi_data
mock_normalize.return_value = sample_csi_data
result = csi_processor.preprocess_csi_data(sample_csi_data)
assert result == sample_csi_data
```
This is a 5-level deep `with` block that obscures the test's intent.
### 1.5 Mock Usage Analysis
**Over-mocking (Critical):**
The TDD test files suffer from severe over-mocking. In `test_csi_processor_tdd.py:168-182`, the preprocessing test mocks out `_remove_noise`, `_apply_windowing`, and `_normalize_amplitude` -- the very functions being tested. The test only verifies that the mocks were called, not that the pipeline works correctly. Compare with `test_csi_processor.py:56-61`:
```python
def test_preprocess_returns_csi_data(self, csi_processor, sample_csi):
result = csi_processor.preprocess_csi_data(sample_csi)
assert isinstance(result, CSIData)
```
This test actually exercises the real code and validates the output type.
**Over-mocking count:** 14 of 25 tests in `test_csi_processor_tdd.py` mock internal methods rather than collaborators. This violates the London School TDD principle -- London School mocks *collaborators*, not the system under test's own private methods.
Similarly in `test_phase_sanitizer_tdd.py`, 12 of 31 tests mock internal methods (`_detect_outliers`, `_interpolate_outliers`, `_apply_moving_average`, `_apply_low_pass_filter`).
**Appropriate mock usage:**
`test_router_interface.py` correctly uses `@patch('paramiko.SSHClient')` to mock the SSH external dependency. This is textbook London School TDD -- mocking the collaborator (SSH client) to test the router interface's behavior.
`test_esp32_binary_parser.py:129-177` uses a real UDP socket with `threading.Thread` for the mock server -- excellent integration test design that avoids over-mocking.
### 1.6 Edge Case Coverage
**Excellent edge case coverage:**
`test_sensing.py` (45 tests) provides outstanding edge case coverage:
- Constant signals (`test_constant_signal_features`, line 327)
- Too few samples (`test_too_few_samples`, line 339)
- Cross-receiver agreement (`test_cross_receiver_agreement_boosts_confidence`, line 513)
- Confidence bounds checking (`test_confidence_bounded_0_to_1`, line 501)
- Multi-frequency band isolation (`test_band_isolation_multi_frequency`, line 308)
- Empty band power (`test_band_power_zero_for_empty_band`, line 697)
- Platform availability detection with mocked proc filesystem (lines 716-807)
`test_esp32_binary_parser.py` covers:
- Valid frame parsing (line 72)
- Frame too short (line 98)
- Invalid magic number (line 103)
- Multi-antenna frames (line 111)
- UDP timeout (line 179)
**Poor edge case coverage:**
`test_densepose_head.py` lacks tests for:
- Batch size of 0
- Non-square input sizes
- Very large batch sizes (memory limits)
- NaN/Inf in input tensors
- Half-precision (float16) inputs
`test_modality_translation.py` lacks tests for:
- Gradient clipping behavior
- Learning rate sensitivity
- Numerical stability with extreme values
### 1.7 Test Isolation
**Shared state issues:**
`test_sensing.py` -- The `SimulatedCollector` tests are well-isolated using seeds, but `TestCommodityBackend.test_full_pipeline` (line 592) directly accesses `collector._buffer` (private attribute). If the internal buffer implementation changes, this test breaks.
`test_csi_processor_tdd.py:326-354` -- Tests manipulate `csi_processor._total_processed`, `_processing_errors`, and `_human_detections` directly. These are private attributes and the tests are coupled to implementation details.
**No test order dependencies found.** All test files use proper fixture setup via `@pytest.fixture` or `setup_method`.
### 1.8 Flakiness Indicators
**Timing-dependent tests:**
- `test_phase_sanitizer.py:89-95` -- Asserts processing time `< 0.005` (5ms). This is fragile on CI with variable load.
- `test_csi_processor.py:93-98` -- Asserts preprocessing time `< 0.010` (10ms). Same concern.
- `test_csi_pipeline.py:202-222` -- Asserts pipeline processing `< 0.1s`. Better but still fragile.
**Non-deterministic tests:**
- `test_densepose_head.py:256-267` -- Training mode dropout test asserts outputs are different. With very small dropout rates or specific random seeds, outputs could occasionally match. The `atol=1e-6` tolerance is tight.
- `test_modality_translation.py:145-155` -- Same dropout randomness concern.
**Network-dependent tests:**
- `test_esp32_binary_parser.py:129-177` -- Uses real UDP sockets with `time.sleep(0.2)`. Could fail under network congestion or slow CI.
- `test_esp32_binary_parser.py:179-206` -- UDP timeout test with `timeout=0.5`. Race condition possible.
### 1.9 E2E and Performance Test Quality
**E2E tests (`test_healthcare_scenario.py`):**
This 735-line file defines its own mock classes (`MockPatientMonitor`, `MockHealthcareNotificationSystem`) rather than using the actual system. This makes it a **component integration test**, not a true E2E test. The test names include "should_fail_initially" comments suggesting TDD red-phase artifacts that were never cleaned up:
```python
# Line 348
async def test_fall_detection_workflow_should_fail_initially(self, ...):
```
Despite the names, these tests actually pass (they test the mock objects successfully). The naming is misleading.
**Performance tests (`test_inference_speed.py`):**
All 14 tests use `MockPoseModel` with `asyncio.sleep()` simulating inference time. These tests measure sleep accuracy, not actual inference performance. They are **simulation tests**, not performance tests. Every assertion like `assert inference_time < 100` is testing asyncio scheduling, not model performance.
**Recommendation:** Either rename these to "simulation tests" or replace `MockPoseModel` with actual model inference.
### 1.10 Test Infrastructure Quality
**Fixtures (`archive/v1/tests/fixtures/csi_data.py`):**
Well-designed `CSIDataGenerator` class (487 lines) with:
- Multiple scenario generators (empty room, single person, multi-person)
- Noise injection (`add_noise`)
- Hardware artifact simulation (`simulate_hardware_artifacts`)
- Time series generation
- Validation utilities (`validate_csi_sample`)
**Mocks (`archive/v1/tests/mocks/hardware_mocks.py`):**
Comprehensive mock infrastructure (716 lines) including:
- `MockWiFiRouter` with realistic CSI streaming
- `MockRouterNetwork` for multi-router scenarios
- `MockSensorArray` for environmental monitoring
- Factory functions (`create_test_router_network`, `setup_test_hardware_environment`)
These are well-engineered but used in only 1-2 test files. The E2E test defines its own mocks instead of using these.
---
## 2. Rust Test Suite Analysis
### 2.1 Test Distribution
| Category | Test Count | Source |
|----------|-----------|--------|
| Inline unit tests (`#[cfg(test)]`) | ~2,600 | 292 source files |
| Integration tests (`crates/*/tests/`) | ~58 | 16 integration test files |
| **Total** | **~2,658** | |
The Rust suite is the largest by far, with 1,031+ tests confirmed passing per the project's pre-merge checklist.
### 2.2 Integration Test Quality
**`wifi-densepose-train/tests/test_losses.rs` (18 tests):**
Excellent test quality. Key observations:
- All tests use deterministic data (no `rand` crate, no OS entropy) -- explicitly documented in the module docstring (line 9).
- Feature-gated behind `#[cfg(feature = "tch-backend")]` with a fallback test (line 447) that ensures compilation when the feature is disabled.
- Tests validate mathematical properties, not just "it doesn't crash":
- `gaussian_heatmap_peak_at_keypoint_location` (line 55) -- Verifies the peak value and location
- `gaussian_heatmap_zero_outside_3sigma_radius` (line 84) -- Validates every pixel in the heatmap
- `keypoint_heatmap_loss_invisible_joints_contribute_nothing` (line 229) -- Tests visibility masking
- Clear naming convention: `<function_name>_<expected_behavior>`
**`wifi-densepose-signal/tests/validation_test.rs` (10 tests):**
Outstanding validation tests that prove algorithm correctness against known mathematical results:
- `validate_phase_unwrapping_correctness` (line 17) -- Creates a linearly increasing phase from 0 to 4pi, wraps it, then validates unwrapping reconstructs the original.
- `validate_amplitude_rms` (line 58) -- Uses constant-amplitude data where RMS equals the constant.
- `validate_doppler_calculation` (line 89) -- Computes expected Doppler shift from physics (2 * v * f / c) and validates the implementation matches.
- `validate_complex_conversion` (line 171) -- Round-trip test: amplitude/phase to complex and back.
- `validate_correlation_features` (line 250) -- Uses perfectly correlated antenna data to validate correlation > 0.9.
These tests demonstrate mathematical rigor rarely seen in signal processing codebases.
**`wifi-densepose-mat/tests/integration_adr001.rs` (6 tests):**
Clean integration tests for the disaster response pipeline:
- Deterministic breathing signal generator (16 BPM sinusoid at 0.267 Hz)
- Triage logic verification with explicit expected outcomes per breathing pattern
- Input validation (mismatched lengths, empty data)
- Determinism verification test (line 190) -- runs generator twice and asserts bitwise equality
### 2.3 Inline Test Patterns
The 292 source files with `#[cfg(test)]` modules show consistent patterns:
**Builder pattern testing** is common across crates:
```rust
CsiData::builder()
.amplitude(amplitude)
.phase(phase)
.build()
.unwrap()
```
**Feature-gated tests** prevent compilation failures when optional dependencies are unavailable. The `tch-backend` feature gate pattern is well-applied.
### 2.4 Missing Rust Test Coverage
Based on the crate list and test file analysis:
- `wifi-densepose-api` -- No integration tests for API routes found
- `wifi-densepose-db` -- No database integration tests found
- `wifi-densepose-config` -- No configuration edge case tests found
- `wifi-densepose-wasm` -- No WASM-specific tests beyond budget compliance
- `wifi-densepose-cli` -- No CLI integration tests found
These gaps are less concerning for crates that are primarily thin wrappers, but the API and DB crates warrant integration testing.
---
## 3. Mobile Test Suite Analysis (ui/mobile)
### 3.1 Test Distribution
| Category | Files | Tests | % |
|----------|-------|-------|---|
| Components | 7 | 33 | 16.2% |
| Screens | 5 | 25 | 12.3% |
| Hooks | 3 | 13 | 6.4% |
| Services | 4 | 37 | 18.1% |
| Stores | 3 | 52 | 25.5% |
| Utils | 3 | 42 | 20.6% |
| Test Utils/Mocks | 2 | 2 | 1.0% |
| **Total** | **27** | **204** | **100%** |
### 3.2 Component Test Quality
**Shallow smoke tests dominate.** Most component tests only verify rendering without crashing:
`GaugeArc.test.tsx:28-63` -- All 4 tests follow the same pattern:
```typescript
it('renders without crashing', () => {
const { toJSON } = renderWithTheme(<GaugeArc ... />);
expect(toJSON()).not.toBeNull();
});
```
This verifies the component doesn't throw, but doesn't test:
- Visual output correctness (arc calculation, text rendering)
- Prop-driven behavior changes
- Accessibility attributes
- Edge cases (value > max, negative values, value = 0)
**Better examples:**
`ringBuffer.test.ts` (20 tests) -- Comprehensive boundary testing:
- Zero capacity (line 21)
- Negative capacity (line 25)
- NaN capacity (line 29)
- Infinity capacity (line 33)
- Overflow behavior (line 46)
- Copy semantics (line 67)
- Min/max without comparator (line 98, 129)
`matStore.test.ts` (18 tests) -- Good state management tests:
- Initial state verification (lines 69-87)
- Upsert idempotency (lines 97-107)
- Multiple distinct entities (lines 109-113)
- Selection and deselection (lines 187-197)
### 3.3 Service Test Quality
`api.service.test.ts` (14 tests) -- Well-structured service tests:
- URL building edge cases (trailing slash, absolute URLs, empty base)
- Error normalization (Axios errors, generic errors, unknown errors)
- Retry logic verification (3 total calls, recovery on second attempt)
This is the best-tested service in the mobile suite.
### 3.4 Hook Test Quality
`usePoseStream.test.ts` (4 tests) -- Minimal hook tests:
- Only verifies module exports and store shape
- Cannot test actual hook behavior without rendering context
- Line 20-38: Tests the store, not the hook
**Missing:** No `renderHook()` usage from `@testing-library/react-hooks`. Hooks should be tested with the `renderHook` utility.
### 3.5 Missing Mobile Test Coverage
- No gesture interaction tests
- No navigation flow tests
- No dark/light theme switching tests
- No offline/error state rendering tests
- No accessibility (a11y) tests
- No snapshot tests for UI regression
- No WebSocket reconnection logic tests
---
## 4. Cross-Cutting Analysis
### 4.1 Test Pyramid Balance
| Layer | Python | Rust | Mobile | Project Total | Ideal |
|-------|--------|------|--------|---------------|-------|
| Unit | 66% | ~98% | 62% | ~92% | 70% |
| Integration | 22% | ~2% | 20% | ~5% | 20% |
| E2E/Perf | 7% | ~0% | 0% | ~1% | 10% |
| System/Acceptance | 5% (mocked) | 0% | 18% (screens) | ~2% | -- |
**Assessment:** The pyramid is top-heavy on unit tests due to the massive Rust inline test suite. Integration and E2E layers are weak across the board.
### 4.2 Duplicate Coverage Map
| Module | Files Testing It | Redundant Tests |
|--------|-----------------|-----------------|
| CSI Extractor | 5 Python files | ~90 |
| Phase Sanitizer | 2 Python files | ~7 |
| Router Interface | 2 Python files | ~13 |
| CSI Processor | 2 Python files | ~6 |
| **Total redundant** | | **~116** |
### 4.3 Test Gap Analysis
**Untested or under-tested areas:**
| Component | Gap Description | Risk |
|-----------|----------------|------|
| REST API (Python) | `test_api_endpoints.py` exists but uses mocks for all HTTP | High |
| WebSocket streaming | `test_websocket_streaming.py` exists but no real connection | High |
| ESP32 firmware | C code has no automated tests | Critical |
| Database layer (Rust) | No integration tests for `wifi-densepose-db` | Medium |
| Cross-crate integration | No tests validating crate dependency chains | Medium |
| Configuration validation | `wifi-densepose-config` has minimal test coverage | Low |
| WASM edge deployment | Only budget compliance tests | Medium |
| Mobile navigation | No screen transition tests | Medium |
| Mobile WebSocket | `ws.service.test.ts` exists but limited coverage | High |
### 4.4 Test Maintenance Burden
**High maintenance cost files:**
1. `archive/v1/tests/mocks/hardware_mocks.py` (716 lines) -- Complex mock infrastructure that must evolve with the production code. Any hardware interface change requires updating this file.
2. `archive/v1/tests/fixtures/csi_data.py` (487 lines) -- Rich data generation but duplicates some logic from the production `SimulatedCollector`.
3. The 5 CSI extractor test files collectively contain ~3,000 lines of test code for a single module. Merging to one file would reduce this to ~600 lines.
**Brittle test indicators:**
- Tests that access private attributes (`_buffer`, `_total_processed`, etc.): 8 occurrences
- Tests with magic number assertions (`< 0.005`, `< 0.010`): 5 occurrences
- Tests with `asyncio.sleep()` for synchronization: 12 occurrences
---
## 5. Specific File-Level Findings
### 5.1 Best Test Files (Exemplary Quality)
| File | Why It's Good |
|------|---------------|
| `archive/v1/tests/unit/test_sensing.py` | 45 tests with mathematical rigor, known-signal validation, domain-specific edge cases, cross-receiver agreement, band isolation. No mocks for core logic. |
| `archive/v1/tests/unit/test_esp32_binary_parser.py` | Real UDP socket testing, struct-level binary validation, ADR-018 compliance. Tests actual I/Q to amplitude/phase math. |
| `v2/.../tests/validation_test.rs` | Physics-based validation (Doppler, phase unwrapping, spectral analysis). Tests prove algorithm correctness, not just non-failure. |
| `v2/.../tests/test_losses.rs` | Deterministic data, feature-gated, tests mathematical properties (zero loss for identical inputs, non-zero for mismatched). |
| `ui/mobile/.../utils/ringBuffer.test.ts` | Comprehensive boundary testing (NaN, Infinity, 0, negative, overflow). Tests copy semantics. |
### 5.2 Worst Test Files (Needs Improvement)
| File | Issues |
|------|--------|
| `archive/v1/tests/performance/test_inference_speed.py` | Tests `asyncio.sleep()` accuracy, not model performance. `MockPoseModel` simulates inference with sleep. |
| `archive/v1/tests/e2e/test_healthcare_scenario.py` | Not a real E2E test -- defines its own mock classes. Test names contain stale "should_fail_initially" text. |
| `archive/v1/tests/unit/test_csi_processor_tdd.py` | 14/25 tests mock the SUT's own private methods. Tests verify mock calls, not behavior. |
| `archive/v1/tests/unit/test_phase_sanitizer_tdd.py` | 12/31 tests mock internal methods. Same anti-pattern as csi_processor_tdd. |
| `ui/mobile/.../components/GaugeArc.test.tsx` | All 4 tests are `expect(toJSON()).not.toBeNull()` -- smoke tests with no behavioral verification. |
---
## 6. Recommendations
### Priority 1: Eliminate Duplication (Effort: Low, Impact: High)
1. **Consolidate CSI extractor tests** into a single file. Retain `test_csi_standalone.py` (most comprehensive), delete the other four. This removes ~90 redundant tests and ~2,400 lines of duplicate code.
2. **Consolidate TDD pairs** -- Merge `test_phase_sanitizer.py` into `test_phase_sanitizer_tdd.py`, `test_router_interface.py` into `test_router_interface_tdd.py`, `test_csi_processor.py` into `test_csi_processor_tdd.py`.
### Priority 2: Fix Mock Anti-Patterns (Effort: Medium, Impact: High)
3. **Replace internal-method mocking** in `test_csi_processor_tdd.py` and `test_phase_sanitizer_tdd.py` with real execution tests. Mock only external collaborators (SSH, hardware, network).
4. **Replace `MockPoseModel`** in performance tests with actual model inference or clearly label these as "simulation tests."
### Priority 3: Add Missing Test Coverage (Effort: High, Impact: High)
5. **Add real integration tests** for the REST API and WebSocket endpoints using `httpx.AsyncClient` or similar.
6. **Add Rust integration tests** for `wifi-densepose-api`, `wifi-densepose-db`, and `wifi-densepose-cli` crates.
7. **Upgrade mobile component tests** from smoke tests to behavioral tests with prop variation, user interaction, and accessibility checks.
### Priority 4: Reduce Flakiness Risk (Effort: Low, Impact: Medium)
8. **Remove or widen timing assertions** in `test_phase_sanitizer.py:89` and `test_csi_processor.py:93`. Use `pytest-benchmark` for performance measurement, not inline time assertions.
9. **Add retry logic to UDP socket tests** in `test_esp32_binary_parser.py` or use mock sockets for unit-level testing.
### Priority 5: Standardize Conventions (Effort: Low, Impact: Low)
10. **Standardize test naming** to `test_should_<behavior>` (BDD-style) across all Python tests.
11. **Add pytest markers** consistently: `@pytest.mark.unit`, `@pytest.mark.integration`, `@pytest.mark.slow` for performance tests.

## 1. Executive Summary
The WiFi-DensePose system demonstrates strong architectural foundations with a well-structured FastAPI backend, a mature React Native mobile app, and a comprehensive CLI. However, the quality experience is uneven across touchpoints, with several gaps that impact different user personas in distinct ways.
### Key Findings
**Strengths:**
- Comprehensive error handling middleware with structured error responses, request IDs, and environment-aware detail levels (`archive/v1/src/middleware/error_handler.py`)
- Robust WebSocket reconnection with exponential backoff and automatic simulation fallback in the mobile app (`ui/mobile/src/services/ws.service.ts`)
- Well-designed health check architecture with component-level status, readiness probes, and liveness endpoints (`archive/v1/src/api/routers/health.py`)
- Strong input validation on API models with Pydantic, including range constraints and clear field descriptions (`archive/v1/src/api/routers/pose.py`)
- Persistent settings with AsyncStorage in the mobile app, surviving app restarts (`ui/mobile/src/stores/settingsStore.ts`)
- Server URL validation with test-before-save workflow in mobile settings (`ui/mobile/src/screens/SettingsScreen/ServerUrlInput.tsx`)
**Critical Issues:**
- API documentation is disabled in production (`docs_url=None`, `redoc_url=None` when `is_production=True`), leaving production API consumers without discoverability (in `archive/v1/src/api/main.py` line 146-148)
- No user-facing progress indicator during calibration -- the calibration endpoint returns an estimated duration but there is no polling endpoint progress beyond percentage (`archive/v1/src/api/routers/pose.py` lines 320-361)
- Rate limit responses lack a human-readable `Retry-After` message body; the client receives a bare `"Rate limit exceeded"` string with retry information only in HTTP headers (`archive/v1/src/middleware/rate_limit.py` line 323)
- CLI `status` command uses emoji/Unicode characters that break in terminals without UTF-8 support (`archive/v1/src/commands/status.py` lines 360-474)
- Mobile app `MainTabs.tsx` passes an inline arrow function as the `component` prop to `Tab.Screen` (line 130), causing unnecessary re-renders on every parent render cycle
**Top 3 Recommendations:**
1. Add a separate production API documentation URL (e.g., `/api-docs`) with authentication, rather than removing docs entirely
2. Implement a WebSocket-based calibration progress stream or add a polling endpoint that returns step-by-step progress
3. Add a `--no-emoji` CLI flag or auto-detect terminal capabilities to avoid broken status output

## 3. User Journey Analysis by Persona
### 3.1 Developer Persona
**Journey**: Clone repo -> Set up environment -> Build -> Run tests -> Develop -> Submit PR
| Step | Success Rate | Pain Level | Bottleneck |
|------|-------------|------------|------------|
| Clone & orient | Moderate | MEDIUM | Multiple codebases (Python v1, Rust, firmware, mobile) with no single entry point guide |
| Environment setup | Low | HIGH | Requires Python + Rust toolchain + Node.js + ESP-IDF for full development |
| Build Python API | Moderate | MEDIUM | Dependency management not containerized for easy onboarding |
| Run Rust tests | High | LOW | `cargo test --workspace --no-default-features` works reliably (1,031+ tests) |
| Run Python tests | Moderate | MEDIUM | Requires database setup, Redis optional but affects behavior |
| Contribute to mobile | Moderate | MEDIUM | Expo/React Native setup is standard but undocumented within this repo |
**Key Findings:**
- `CLAUDE.md` is comprehensive for AI agents but not optimized for human developers; it mixes agent configuration with build instructions
- No `CONTRIBUTING.md` file exists
- Build commands are scattered: Python uses `pip`, Rust uses `cargo`, mobile uses `npm`, firmware uses ESP-IDF
- Test commands differ between `npm test`, `cargo test`, and `python -m pytest` with no unified runner
- The pre-merge checklist in `CLAUDE.md` has 12 items, which is thorough but creates friction for external contributors
### 3.2 Operator Persona
**Journey**: Install -> Configure -> Start server -> Monitor -> Troubleshoot
| Step | Success Rate | Pain Level | Bottleneck |
|------|-------------|------------|------------|
| Install | Low | HIGH | No single installation script or Docker Compose for the full stack |
| Configure | Moderate | MEDIUM | Config file path must be specified; no `--init` to generate default config |
| Start server | Moderate | MEDIUM | `wifi-densepose start` works but database must be initialized first |
| Monitor status | High | LOW | `wifi-densepose status --detailed` provides comprehensive output |
| Stop server | High | LOW | Both graceful and force-stop options available |
| Troubleshoot | Low | HIGH | Error messages reference internal exceptions; no runbook or FAQ |
**Key Findings:**
- The CLI offers `start`, `stop`, `status`, `db init/migrate/rollback`, `config show/validate/failsafe`, `tasks run/status`, and `version` -- a reasonable command set
- However, there is no `wifi-densepose init` command to scaffold a working configuration from scratch
- The `config validate` command checks database, Redis, and directory availability -- good for operators
- The `config failsafe` command showing SQLite fallback status is a strong resilience feature
- Missing: log rotation configuration, log level adjustment at runtime, and a `wifi-densepose doctor` self-diagnosis command
### 3.3 End-User Persona (Mobile App User)
**Journey**: Open app -> Connect to server -> View live data -> Check vitals -> Manage zones -> Configure settings
| Step | Success Rate | Pain Level | Bottleneck |
|------|-------------|------------|------------|
| Open app | High | LOW | Clean initial load with loading spinners |
| Connect to server | Moderate | MEDIUM | Default URL is `localhost:3000` which will not work on physical devices |
| View live data | High | LOW | Simulation fallback ensures something is always displayed |
| Check vitals | High | LOW | Gauges, sparklines, and classification render smoothly |
| Manage zones | Moderate | LOW | Heatmap visualization is functional |
| Configure settings | High | LOW | Server URL validation, test connection, save workflow is solid |
**Key Findings:**
- The default `serverUrl` in `settingsStore.ts` is `http://localhost:3000`, which will fail on a physical device where the server runs on a different machine; a first-run setup wizard would improve this
- Connection state management is well-implemented with three visible states: `LIVE STREAM`, `SIMULATED DATA`, and `DISCONNECTED` via `ConnectionBanner.tsx`
- The simulation fallback (`generateSimulatedData()`) activates automatically when WebSocket connection fails, ensuring the app never shows a blank screen
- The MAT (Mass Casualty Assessment Tool) screen seeds a training scenario on first load, which may confuse users who expect a clean state
- `ErrorBoundary` provides crash recovery with a "Retry" button, but the error message is the raw JavaScript error (`error.message`) without user-friendly context

## 4. API Experience Analysis
### 4.1 Endpoint Structure (Score: 82/100)
The API follows RESTful conventions with clear resource paths:
```
GET /health/health - System health
GET /health/ready - Readiness probe
GET /health/live - Liveness probe
GET /health/metrics - System metrics (auth required for detailed)
GET /health/version - Version info
GET /api/v1/pose/current - Current pose estimation
POST /api/v1/pose/analyze - Custom analysis (auth required)
GET /api/v1/pose/zones/{zone_id}/occupancy - Zone occupancy
GET /api/v1/pose/zones/summary - All zones summary
POST /api/v1/pose/historical - Historical data (auth required)
GET /api/v1/pose/activities - Recent activities
POST /api/v1/pose/calibrate - Start calibration (auth required)
GET /api/v1/pose/calibration/status - Calibration status
GET /api/v1/pose/stats - Statistics
WS /api/v1/stream/pose - Real-time pose stream
WS /api/v1/stream/events - Event stream
```
**Issues Found:**
- `GET /health/health` is redundant path nesting; the health router is mounted at `/health` prefix, making the full path `/health/health`. This should be `/health` (root of the health router) or the prefix should be `/` for the health router
- `POST /api/v1/pose/historical` uses POST for a read operation. While this is common for complex queries, it violates REST conventions. A `GET` with query parameters or a `POST /api/v1/pose/query` would be clearer
- The root endpoint (`GET /`) exposes feature flags (`authentication`, `rate_limiting`) which could leak security posture information
### 4.2 Error Handling (Score: 85/100)
The `ErrorHandler` class in `archive/v1/src/middleware/error_handler.py` is well-designed:
**Strengths:**
- Structured error responses with consistent format: `{ "error": { "code": "...", "message": "...", "timestamp": "...", "request_id": "..." } }`
- Request ID tracking via `X-Request-ID` header for debugging
- Environment-aware: tracebacks included in development, hidden in production
- Specialized handlers for HTTP, validation, Pydantic, database, and external service errors
- Custom exception classes (`BusinessLogicError`, `ResourceNotFoundError`, `ConflictError`, `ServiceUnavailableError`) with domain context
**Issues Found:**
- The `ErrorHandlingMiddleware` class exists but is commented out (line 432-434 in `error_handler.py`), meaning errors are handled by `setup_error_handling()` exception handlers instead. The middleware class and the exception handlers use different `ErrorHandler` instances, creating potential inconsistency if one is changed without the other
- The `_is_database_error()` check uses string matching on module names (line 355-373), which is fragile. `"ConnectionError"` will match `aiohttp.ConnectionError` (an external service error), not just database connection errors
- Error responses do not include a `documentation_url` field that could guide users to relevant docs
### 4.3 Rate Limiting UX (Score: 72/100)
**Strengths:**
- Dual algorithm support: sliding window counter and token bucket
- Per-endpoint rate limiting with per-user differentiation
- Standard `X-RateLimit-*` headers on all responses
- `Retry-After` header on 429 responses
- Health/docs/metrics paths exempted from rate limiting
- Configurable presets for development, production, API, and strict modes
**Issues Found:**
- The 429 response body is `"Rate limit exceeded"` (a plain string). No structured error response with the `ErrorResponse` format is used. The rate limit middleware raises `HTTPException` directly rather than using `CustomHTTPException` or `ErrorResponse`
- No information about which rate limit bucket was exhausted (per-IP vs per-user vs per-endpoint)
- No rate limit dashboard or endpoint to check current rate limit status without making a request
- The `RateLimitConfig` presets (development, production, api, strict) are defined but there is no CLI command or API endpoint to switch between them
### 4.4 WebSocket Experience (Score: 80/100)
**Strengths:**
- Connection confirmation message with client ID and configuration on connect
- Structured message protocol with `type` field (`ping`, `update_config`, `get_status`)
- Invalid JSON is handled gracefully with an error message back to client
- Stale connection cleanup every 60 seconds with 5-minute timeout
- Zone-based and stream-type-based filtering for broadcasts
- Client-side config updates without reconnection via `update_config` message
**Issues Found:**
- Authentication is checked _after_ `websocket.accept()` (line 80-93 in `stream.py`), meaning unauthenticated clients briefly hold a connection before being closed. This wastes resources and leaks the existence of the endpoint
- The `handle_websocket_message` function handles unknown message types with an error, but does not suggest valid message types: `"Unknown message type: foo"` should list valid options
- No heartbeat/keepalive mechanism initiated from the server. The client must send ping messages. If the client does not ping, the connection will be considered stale after 5 minutes even if data is flowing
- Close codes are not documented for clients to handle reconnection logic
### 4.5 API Documentation & Discoverability (Score: 58/100)
**Issues Found:**
- Swagger UI (`/docs`) and ReDoc (`/redoc`) are **disabled in production** (line 146-148 of `main.py`): `docs_url=settings.docs_url if not settings.is_production else None`
- No alternative documentation hosting for production environments
- The `GET /` root endpoint and `GET /api/v1/info` endpoint provide feature information but no link to documentation
- Pydantic models have good `Field(description=...)` annotations, which would generate useful OpenAPI docs -- but only visible in development
- No API changelog or versioning documentation beyond the `version` field
---
## 5. CLI Experience Analysis
### 5.1 Command Structure (Score: 70/100)
The CLI uses Click with a nested group structure:
```
wifi-densepose [--config FILE] [--verbose] [--debug]
start [--host] [--port] [--workers] [--reload] [--daemon]
stop [--force] [--timeout]
status [--format text|json] [--detailed]
db
init [--url]
migrate [--revision]
rollback [--steps]
tasks
run [--task cleanup|monitoring|backup]
status
config
show
validate
failsafe [--format text|json]
version
```
**Strengths:**
- Logical grouping of commands (server, db, tasks, config)
- Global options `--config`, `--verbose`, `--debug` available on all commands
- `--daemon` mode with PID file management and stale PID detection
- JSON output format option on `status` and `failsafe` for scripting
**Issues Found:**
- No shell completion support (Click supports it but it is not configured)
- No `init` or `setup` command to generate a default configuration file
- No `logs` command to tail or search server logs
- The `tasks status` subcommand shadows the parent `status` command in Click's namespace (line 347-348 in `cli.py` defines `def status(ctx):` under the `tasks` group), which works but creates confusion
- No `--quiet` option for scripting (opposite of `--verbose`)
- Error output goes through `logger.error()` which depends on logging configuration; if logging is misconfigured, errors are silently lost
### 5.2 Error Messages (Score: 60/100)
**Issues Found:**
- Errors from `start` command show the raw exception: `"Failed to start server: {e}"` where `{e}` is the Python exception string
- No suggestion for common failure scenarios. For example, if the database connection fails during `start`, the error is `"Database connection failed: [psycopg2 error]"` with no guidance like "Check your DATABASE_URL setting" or "Run 'wifi-densepose db init' first"
- The `config validate` command outputs check-style messages (`"X Database connection: FAILED - {e}"`) which is helpful, but the X and checkmark characters use Unicode that may not render in all terminals
- The `stop` command handles "Server is not running" gracefully, which is good
- Missing: error codes that users could search for in documentation
### 5.3 Help Text (Score: 65/100)
**Strengths:**
- Each command has a one-line description
- Options have help text and defaults documented
**Issues Found:**
- No examples in help text. The argparse `epilog` pattern used in `provision.py` is good practice but is not used in the Click CLI
- No `--help` examples showing common workflows like "Start a development server", "Deploy to production", or "Initialize a fresh installation"
- Command descriptions are terse: `"Start the WiFi-DensePose API server"` does not mention prerequisites
### 5.4 Configuration Workflow (Score: 68/100)
**Strengths:**
- `config show` displays the full configuration without secrets
- `config validate` checks database, Redis, and directory access
- `config failsafe` shows SQLite fallback and Redis degradation status
- Settings can be loaded from a file via `--config` flag
**Issues Found:**
- No `config init` to generate a template configuration file
- No `config set KEY VALUE` to modify individual settings
- No environment variable listing showing which variables affect configuration
- The `config show` output dumps JSON but does not annotate which values are defaults vs user-configured
---
## 6. Mobile App UX Analysis
### 6.1 Screen Flow Architecture (Score: 82/100)
The app uses a bottom tab navigator with five screens:
```
Live (wifi icon) -> Vitals (heart) -> Zones (grid) -> MAT (shield) -> Settings (gear)
```
**Strengths:**
- Lazy loading of all screens with `React.lazy` and suspense fallbacks showing loading indicator with screen name
- Fallback placeholder screens for any screen that fails to load: `"{label} screen not implemented yet"` with a "Placeholder shell" subtitle
- MAT screen badge showing alert count in the tab bar
- Icon mapping is clear and semantically appropriate
**Issues Found:**
- `MainTabs.tsx` line 130: `component={() => <Suspended component={component} />}` creates a new function reference on every render. This should be refactored to a stable component reference to prevent unnecessary tab re-renders
- No deep linking support for navigating directly to a screen from a notification or external URL
- No screen transition animations configured; the default tab switch is abrupt
- Tab labels use `fontFamily: 'Courier New'` which may not be available on all devices, with no fallback font specified
### 6.2 Connection Handling (Score: 88/100)
The WebSocket connection strategy in `ws.service.ts` is well-designed:
**Strengths:**
- Exponential backoff reconnection: delays of 1s, 2s, 4s, 8s, 16s
- Maximum 10 reconnection attempts before falling back to simulation
- Simulation mode provides continuous data display even when disconnected
- Connection status propagated to all screens via Zustand store
- Clean disconnect with close code 1000
- Auto-connect on app mount via `usePoseStream` hook
- URL validation before attempting connection
**Issues Found:**
- When reconnecting, the simulation timer starts immediately during the backoff delay, which means the user briefly sees "SIMULATED DATA" then "LIVE STREAM" then potentially "SIMULATED DATA" again if the reconnect fails. This creates a flickering experience
- No user notification when switching between live and simulated modes beyond the banner color change
- The WebSocket URL construction in `buildWsUrl()` hardcodes the path `/ws/sensing`, but the API server expects `/api/v1/stream/pose`. This path mismatch (`WS_PATH = '/api/v1/stream/pose'` in `constants/websocket.ts` vs `/ws/sensing` in `ws.service.ts`) is a potential connection failure point
- No explicit ping/pong keepalive from the client; relies on the WebSocket protocol's built-in mechanism
### 6.3 Loading & Error States (Score: 78/100)
**Strengths:**
- `LoadingSpinner` component with smooth rotation animation using `react-native-reanimated`
- `ErrorBoundary` wraps the LiveScreen with crash recovery
- LiveScreen shows a dedicated error state with "Live visualization failed", the error message, and a "Retry" button
- Retry increments a `viewerKey` to force component remount
- `ConnectionBanner` provides three distinct visual states with semantic colors (green/amber/red)
**Issues Found:**
- The `ErrorBoundary` shows `error.message` directly, which may be a technical JavaScript error string like `"Cannot read property 'x' of undefined"`. A user-friendly message mapping would improve the experience
- No timeout handling on loading states. If the GaussianSplat WebView never fires `onReady`, the loading spinner displays indefinitely
- The VitalsScreen shows `N/A` for features when no data is available, but the gauges (`BreathingGauge`, `HeartRateGauge`) behavior at zero/null values is not guarded in the screen code
- No skeleton loading states; screens jump from blank to fully rendered
### 6.4 State Management (Score: 85/100)
**Strengths:**
- Zustand stores are well-structured with clear separation: `poseStore` (real-time data), `settingsStore` (configuration), `matStore` (MAT data)
- `settingsStore` uses `persist` middleware with AsyncStorage for cross-session persistence
- `poseStore` uses a `RingBuffer` for RSSI history, capping at 60 entries to prevent memory growth
- Clean `reset()` method on `poseStore` to clear all state
**Issues Found:**
- `poseStore` is not persisted, so all historical data is lost on app restart. For a monitoring application, this is a significant gap
- The `handleFrame` method updates 6 state properties atomically in one `set()` call, which is correct, but the `rssiHistory` is computed from a module-level `RingBuffer` that exists outside the store, creating a potential synchronization issue during hot reload
- No state migration strategy for `settingsStore` -- if the schema changes between app versions, persisted state may cause errors
### 6.5 Server Configuration UX (Score: 82/100)
The `ServerUrlInput` component in the Settings screen provides:
**Strengths:**
- Real-time URL validation with `validateServerUrl()` showing error messages inline
- "Test Connection" button that measures and displays response latency
- Visual feedback: border turns red on invalid URL, test result shows checkmark/X with timing
- "Save" button separated from "Test" to allow testing before committing
**Issues Found:**
- Default server URL `http://localhost:3000` will never work on a physical device. The first-run experience should prompt for the server address or attempt auto-discovery via mDNS/Bonjour
- No QR code scanner to configure server URL (common in IoT companion apps)
- Test result is ephemeral -- it disappears when navigating away and returning
- No validation of port range or IP address format beyond URL syntax
- Save does not confirm success to the user; the connection simply restarts silently
---
## 7. Developer Experience (DX) Analysis
### 7.1 Build Process (Score: 65/100)
**Issues Found:**
- Four separate build systems: Python (`pip`/`poetry`), Rust (`cargo`), Node.js (`npm`), and ESP-IDF for firmware
- No unified `Makefile`, `Taskfile`, or `just` file to abstract build commands
- `CLAUDE.md` lists build commands but they are mixed with AI agent configuration
- Docker support is mentioned in the pre-merge checklist but no `docker-compose.yml` for local development was found
- The Rust workspace has 15 crates with a specific publishing order -- this dependency chain is documented but not automated
### 7.2 Testing Experience (Score: 72/100)
**Strengths:**
- Rust workspace has 1,031+ tests with a single command: `cargo test --workspace --no-default-features`
- Deterministic proof verification via `python archive/v1/data/proof/verify.py` with SHA-256 hash checking
- Mobile app has comprehensive test coverage with tests for components, hooks, screens, services, stores, and utilities
- Witness bundle verification with `VERIFY.sh` providing 7/7 pass/fail attestation
**Issues Found:**
- No unified test runner across codebases
- Python test command (`python -m pytest tests/ -x -q`) requires proper environment setup first
- Mobile tests require additional setup (`jest`, React Native testing libraries)
- No integration test suite that tests the full stack (API + WebSocket + Mobile)
- No test coverage reporting configured for the Python codebase
### 7.3 Documentation Quality (Score: 62/100)
**Strengths:**
- 43 Architecture Decision Records (ADRs) in `docs/adr/`
- Domain-Driven Design documentation in `docs/ddd/`
- Comprehensive hardware audit in ADR-028 with witness bundle
- User guide at `docs/user-guide.md`
**Issues Found:**
- No quickstart guide for first-time contributors
- `CLAUDE.md` is 500+ lines but is primarily an AI agent configuration file, not a developer guide
- No API reference documentation beyond the auto-generated Swagger (which is disabled in production)
- No architecture diagram showing how the Python API, Rust core, mobile app, and ESP32 firmware interact
- Missing: changelog is referenced in the pre-merge checklist but its location is not specified
### 7.4 Error Messages for Developers (Score: 70/100)
**Strengths:**
- FastAPI validation errors return field-level details with type, message, and location
- Rust crate errors use typed error types (`wifi-densepose-core`)
- Middleware error handler includes traceback in development mode
**Issues Found:**
- Python API errors in handlers use f-string formatting with raw exception messages: `f"Pose estimation failed: {str(e)}"`. These are user-facing but contain internal details
- No error code catalog or error reference documentation
- Startup validation errors print checkmarks but do not provide remediation steps
### 7.5 Configuration Management (Score: 68/100)
**Strengths:**
- Pydantic `Settings` class with environment variable support
- Configuration file loading via `--config` CLI flag
- Database failsafe with SQLite fallback
- Redis optional with graceful degradation
**Issues Found:**
- No `.env.example` or `.env.template` file to guide environment variable setup
- No configuration schema documentation beyond code inspection
- Sensitive settings (database URL, JWT secret) are validated but error messages do not specify which environment variables to set
- The `config show` command redacts secrets but does not explain where secrets should be configured
---
## 8. Hardware Integration UX Analysis
### 8.1 ESP32 Provisioning Flow (Score: 65/100)
The `provision.py` script in `firmware/esp32-csi-node/` handles WiFi credential and mesh configuration:
**Strengths:**
- Clear `--help` text with usage examples in the argparse epilog
- Parameter validation: TDM slot/total must be specified together, channel ranges validated, MAC format validated
- `--dry-run` option to generate binary without flashing
- Fallback CSV generation when NVS binary generation fails, with manual flash instructions
- Password masked in output: `"WiFi Password: ****"`
- Multiple NVS generator discovery methods (Python module, ESP-IDF bundled script)
**Issues Found:**
- No auto-detection of serial port. The `--port` is required, but users may not know which port their ESP32 is on. A `--port auto` option using `serial.tools.list_ports` would help
- No verification step after flashing to confirm the provisioned values were written correctly
- Error when `esptool` or `nvs_partition_gen` is not installed is a raw Python exception. A friendlier message like `"Required tool 'esptool' not found. Install with: pip install esptool"` would be better
- The script name is `provision.py` but it is invoked as `python firmware/esp32-csi-node/provision.py`, which is a long path. A CLI subcommand like `wifi-densepose hw provision` would integrate better
- 22 command-line arguments is overwhelming; grouped parameter presets (e.g., `--profile basic`, `--profile mesh`, `--profile edge`) would simplify common use cases
- No interactive mode for guided provisioning
### 8.2 Serial Monitoring (Score: 55/100)
**Issues Found:**
- Serial monitoring is done via `python -m serial.tools.miniterm COM7 115200`, which is a raw tool with no structured log parsing
- No custom monitoring tool that parses ESP32 output, highlights errors, or shows CSI data visualization
- No documentation on what serial output to expect during normal operation vs error conditions
- Baud rate (115200) must be known; no auto-baud detection
### 8.3 Firmware Update Process (Score: 60/100)
**Issues Found:**
- Firmware flashing uses `idf.py flash` which requires the full ESP-IDF toolchain
- No OTA (Over-The-Air) update workflow documented for field deployments
- The `ota_data_initial.bin` is listed in the release process but OTA update instructions are not provided
- No firmware version reporting from the device to verify the update was successful
- 8MB and 4MB builds require different `sdkconfig.defaults` files with manual copying

## 9. Cross-Cutting Quality Concerns
### 9.1 Error Handling Quality Across Touchpoints (Score: 73/100)
| Touchpoint | Error Format | User Guidance | Recovery Path |
|------------|-------------|---------------|---------------|
| API REST | Structured JSON with code, message, request_id | No documentation links | Retry logic needed by client |
| API WebSocket | JSON `{ type: "error", message: "..." }` | Lists valid message types: No | Reconnect |
| CLI | Logger output to stderr | No remediation suggestions | Exit code 1 |
| Mobile | `ErrorBoundary` with retry, `ConnectionBanner` | Raw error messages | Retry button, reconnect |
| Provisioning | Python exceptions | Fallback CSV on failure | Manual flash instructions |
**Key Gap**: Error message styles differ between API (structured JSON) and CLI (logger strings). A unified error taxonomy would improve consistency.
### 9.2 Feedback Loops (Score: 72/100)
| Action | Feedback Mechanism | Timeliness | Quality |
|--------|-------------------|------------|---------|
| API request | HTTP status + response body | Immediate | Good |
| WebSocket connect | `connection_established` message | Immediate | Good |
| CLI start | Log messages to stdout | Real-time | Adequate |
| CLI stop | "Server stopped gracefully" | After completion | Good |
| Calibration start | Returns `calibration_id` and `estimated_duration_minutes` | Immediate | Incomplete (no progress stream) |
| Mobile connect | Banner color change | ~1s delay | Good |
| Firmware flash | `print()` statements | Real-time | Adequate |
| Settings save | No confirmation | Silent | Poor |
### 9.3 Recovery Paths (Score: 68/100)
| Failure Scenario | Recovery Path | Automated? | Documentation |
|-----------------|---------------|------------|---------------|
| Database connection fails | SQLite failsafe fallback | Yes | `config failsafe` command |
| Redis unavailable | Continues without Redis, logs warning | Yes | Mentioned in startup output |
| WebSocket disconnects | Exponential backoff reconnection, simulation fallback | Yes | Not documented |
| Stale PID file | Detected and cleaned up on `start`/`stop` | Yes | Not documented |
| API server crash | No automatic restart | No | No systemd/supervisor config |
| Mobile app crash | `ErrorBoundary` with retry | Partial | Not documented |
| Firmware flash fails | Fallback CSV with manual instructions | Partial | Inline help |
| Calibration fails | No documented recovery | No | Not documented |
### 9.4 Accessibility (Score: 45/100)
**Issues Found:**
- Mobile app uses hardcoded hex colors throughout (e.g., `'#0F141E'`, `'#0F6B2A'`, `'#8A1E2A'`) with no high-contrast mode support
- No `accessibilityLabel` or `accessibilityRole` props on interactive components in the mobile app
- `ConnectionBanner` relies on color alone to distinguish states (green/amber/red). The text labels (`LIVE STREAM`, `SIMULATED DATA`, `DISCONNECTED`) help, but there is no screen reader announcement on state change
- CLI status output uses emoji (checkmarks, X marks, weather symbols) as semantic indicators with no text-only fallback
- API documentation (when available) has no known accessibility testing
- No ARIA landmarks or roles in the sensing server web UI (if any)
- Font sizes are fixed in the mobile theme with no dynamic type/accessibility sizing support

## 10. Oracle Problems Detected
### Oracle Problem 1 (HIGH): Production API Documentation vs Security
**Type**: User Need vs Business Need Conflict
- **User Need**: API consumers need documentation to discover and integrate with endpoints
- **Business Need**: Hiding Swagger/ReDoc in production reduces attack surface
- **Conflict**: Disabling docs entirely (`docs_url=None` when `is_production=True`) leaves production API consumers without any discoverability mechanism
**Failure Modes:**
1. Developers working against production endpoints cannot discover available APIs
2. Third-party integrators have no self-service documentation
3. Internal teams must maintain separate documentation that can drift from the actual API
**Resolution Options:**
| Option | User Score | Security Score | Recommendation |
|--------|-----------|---------------|----------------|
| Keep docs disabled | 20 | 95 | Current state |
| Auth-gated docs endpoint | 85 | 80 | Recommended |
| Separate docs site from OpenAPI spec export | 90 | 90 | Best but more effort |
| Rate-limited docs with no auth | 70 | 60 | Compromise |
### Oracle Problem 2 (MEDIUM): Simulation Fallback vs Data Integrity
**Type**: User Experience vs Data Accuracy Conflict
- **User Need**: The app should always show something; blank screens feel broken
- **Business Need**: Users should know when they are seeing real vs simulated data
- **Conflict**: Automatic simulation fallback means users may not realize they lost their real data feed
**Failure Modes:**
1. Operator monitors "activity" that is actually simulated, missing real events
2. MAT (Mass Casualty Assessment) screen shows simulated survivor data during a real incident
3. Vitals screen displays simulated breathing/heart rate data, creating false confidence
**Resolution Options:**
| Option | UX Score | Safety Score | Recommendation |
|--------|---------|-------------|----------------|
| Current: auto-simulate with banner | 80 | 50 | Risky for safety-critical screens |
| Disable simulation on MAT/Vitals screens | 60 | 85 | Recommended |
| Prominent modal overlay for simulated mode | 70 | 80 | Good compromise |
| Require user confirmation to enter simulation | 55 | 90 | Safest |
### Oracle Problem 3 (MEDIUM): WebSocket Path Mismatch
**Type**: Missing Information / Implementation Inconsistency
- **Evidence**: The mobile app's `ws.service.ts` constructs the WebSocket URL as `/ws/sensing` (line 104), while `constants/websocket.ts` defines `WS_PATH = '/api/v1/stream/pose'`. The API server serves WebSocket on `/api/v1/stream/pose` (stream router). These paths do not match.
- **Impact**: The actual connection behavior depends on which path the sensing server uses (the lightweight Axum server may use `/ws/sensing`), but the inconsistency creates confusion and potential silent connection failures
- **Resolution**: Align the WebSocket paths across the mobile app and server, or make the path configurable

## 12. Heuristic Scoring Summary
### Problem Analysis (H1)
| Heuristic | Score | Finding |
|-----------|-------|---------|
| H1.1: Understand the Problem | 75/100 | The system addresses WiFi-based pose estimation well but the quality experience varies significantly across touchpoints. The core problem (sensing and display) is well-solved; the surrounding experience (setup, configuration, debugging) needs work. |
| H1.2: Identify Stakeholders | 70/100 | Three personas (developer, operator, end-user) are implicitly served but not explicitly designed for. The mobile app targets end-users well; the CLI targets operators adequately; developer experience is the weakest. |
| H1.3: Define Quality Criteria | 65/100 | Health checks define "healthy/degraded/unhealthy" but no SLA or quality thresholds are documented. Rate limits are configurable but default values are not justified. |
| H1.4: Map Failure Modes | 72/100 | Database failsafe, Redis degradation, and WebSocket reconnection cover major failure modes. Missing: calibration failure recovery, firmware flash failure recovery, mobile app state corruption. |
### User Needs (H2)
| Heuristic | Score | Finding |
|-----------|-------|---------|
| H2.1: Task Completion | 78/100 | Core tasks (view live data, check vitals, manage zones) are completable. Setup tasks (install, configure, provision) have friction. |
| H2.2: Error Recovery | 68/100 | Some automated recovery (database failsafe, WebSocket reconnect). Missing recovery paths for calibration failure and firmware issues. |
| H2.3: Learning Curve | 60/100 | Steep onboarding across four codebases. No quickstart guide. Mobile app is the most intuitive touchpoint. |
| H2.4: Feedback Clarity | 72/100 | API provides structured feedback. CLI provides log-style feedback. Mobile provides visual feedback. Calibration progress is the biggest gap. |
| H2.5: Consistency | 70/100 | Error formats differ between API (JSON) and CLI (logger). Mobile is internally consistent. Naming conventions mostly aligned. |
### Business Needs (H3)
| Heuristic | Score | Finding |
|-----------|-------|---------|
| H3.1: Reliability | 76/100 | Health checks, failsafes, and reconnection strategies demonstrate reliability focus. No documented SLAs or uptime targets. |
| H3.2: Security Posture | 72/100 | Authentication framework exists but JWT validation is not implemented. Rate limiting is configurable. Production docs are hidden. Secrets redacted in config output. |
| H3.3: Scalability | 68/100 | Multi-worker support, WebSocket connection management, per-endpoint rate limiting. No load testing results or capacity planning documented. |
| H3.4: Maintainability | 74/100 | Well-separated crates, clear module boundaries, typed interfaces. Pre-merge checklist ensures documentation updates. ADR process is mature. |
### Balance (H4)
| Heuristic | Score | Finding |
|-----------|-------|---------|
| H4.1: UX vs Security | 65/100 | Production API docs disabled for security, but no alternative provided. Authentication errors are informative without leaking implementation details. |
| H4.2: Simplicity vs Capability | 68/100 | Provisioning script has 22 parameters. CLI has good grouping but missing convenience features. API has comprehensive endpoints. |
| H4.3: Consistency vs Flexibility | 72/100 | Error handling is structured but not uniform across touchpoints. Settings are flexible (env vars + config file + CLI flags). |
### Impact (H5)
| Heuristic | Score | Finding |
|-----------|-------|---------|
| H5.1: Visible Impact (GUI/UX) | 76/100 | Mobile app provides clear visual states. CLI status output is detailed. API responses are informative. |
| H5.2: Invisible Impact (Performance) | 70/100 | `cpu_percent(interval=1)` in health check blocks for 1 second per request. Rate limiting uses async locks correctly. RingBuffer prevents memory growth. |
| H5.3: Safety Impact | 62/100 | MAT screen auto-simulation is a safety concern. Simulated vitals data could mislead operators. No data provenance indicator beyond the connection banner. |
| H5.4: Data Integrity | 72/100 | Pydantic validation on all inputs. Zone ID existence checks. Time range validation on historical queries. Deterministic proof verification for core pipeline. |
### Creativity (H6)
| Heuristic | Score | Finding |
|-----------|-------|---------|
| H6.1: Novel Testing Approaches | 68/100 | Witness bundle verification is creative. Deterministic proof with SHA-256 is strong. No mutation testing or property-based testing. |
| H6.2: Alternative Perspectives | 65/100 | The simulation fallback is creative but creates oracle problems. Database failsafe is a pragmatic solution. |
| H6.3: Cross-Domain Insights | 70/100 | WiFi CSI for pose estimation is inherently cross-domain (RF + computer vision + IoT). The mobile app's GaussianSplat visualization is innovative. |

# SFDIPOT Product Factors Assessment: wifi-densepose
**Assessment Date:** 2026-04-05
**Assessor:** QE Product Factors Assessor (HTSM v6.3)
**Framework:** James Bach's Heuristic Test Strategy Model -- Product Factors (SFDIPOT)
**Scope:** Full wifi-densepose system -- Rust workspace (18 crates, 153k LoC), Python v1 (105 files, 39k LoC), ESP32 firmware (48 files, 1.6k LoC), CI/CD pipelines (8 workflows)
**Test Count:** 2,618 Rust `#[test]` functions + 33 Python test files
---
## Executive Summary
The wifi-densepose project is an ambitious WiFi-based human pose estimation system spanning five deployment targets (server, desktop, WASM/browser, ESP32 embedded, mobile). This SFDIPOT assessment identifies **47 risk areas** across all seven product factors. The highest concentration of risk lies in **Time** (real-time processing constraints with no latency testing), **Platform** (6 target architectures with limited cross-platform validation), and **Interfaces** (multiple protocol boundaries with incomplete contract testing).
**Overall Risk Rating: HIGH** -- The system's safety-critical use case (Mass Casualty Assessment Tool) combined with multi-platform deployment and real-time signal processing demands rigorous testing that is currently only partially in place.
### Risk Heat Map
| Factor | Risk | Confidence | Test Coverage | Key Concern |
|--------|------|------------|---------------|-------------|
| **Structure** | MEDIUM | High | Good | 18 crates well-organized; MAT lib.rs at 626 lines pushes limit |
| **Function** | HIGH | High | Moderate | Vital signs extraction, pose estimation accuracy unvalidated in production conditions |
| **Data** | MEDIUM | High | Moderate | Proof-of-reality system strong; CSI data integrity across protocols untested |
| **Interfaces** | HIGH | Medium | Low | REST API stub in Rust; Python/Rust boundary undefined; ESP32 serial protocol loosely coupled |
| **Platform** | HIGH | Medium | Low | 6 deployment targets; ESP32 original/C3 excluded but not enforced at build level |
| **Operations** | MEDIUM | Medium | Low | No Dockerfile; firmware OTA path defined but unvalidated end-to-end |
| **Time** | CRITICAL | High | Very Low | 20 Hz target; no latency benchmarks; concurrent multi-node processing untested |

## S -- Structure
### What the product IS
#### S1: Code Integrity
**Finding:** The Rust workspace is well-structured with 18 crates following Domain-Driven Design bounded contexts. The `wifi-densepose-core` crate uses `#![forbid(unsafe_code)]` and provides clean trait abstractions (`SignalProcessor`, `NeuralInference`, `DataStore`). The crate dependency graph has a clear publish order documented in CLAUDE.md.
**Risk: MEDIUM**
- The `wifi-densepose-mat` lib.rs is 626 lines, exceeding the project's own 500-line limit specified in CLAUDE.md. The `DisasterResponse` struct owns 8 fields including an `Arc<dyn EventStore>`, making it a coordination bottleneck.
- The `wifi-densepose-wasm-edge` crate is excluded from the workspace (`exclude = ["crates/wifi-densepose-wasm-edge"]`), meaning `cargo test --workspace` does not exercise it. This creates a coverage gap for edge deployment code (662 lines).
- The `wifi-densepose-api` Rust crate is a 1-line stub (`//! WiFi-DensePose REST API (stub)`), while the Python v1 has a full FastAPI implementation. This implies the Rust port's API surface is incomplete.
**Test Ideas:**
| # | Priority | Test Idea | Automation |
|---|----------|-----------|------------|
| S-01 | P1 | Build `wifi-densepose-wasm-edge` separately (`cargo build -p wifi-densepose-wasm-edge --target wasm32-unknown-unknown`) and run any embedded tests to confirm they pass outside the workspace test run | Integration |
| S-02 | P2 | Measure cyclomatic complexity of `DisasterResponse::scan_cycle` which spans 80+ lines with nested borrows and conditional event emission -- flag if complexity exceeds 15 | Unit |
| S-03 | P2 | Run `cargo check --workspace --all-features` to surface feature-flag interaction issues across all 18 crates that are hidden by `--no-default-features` in CI | Integration |
| S-04 | P3 | Count lines per file across all crates; flag any `.rs` file exceeding the 500-line project policy | Lint/CI |
#### S2: Dependencies
**Finding:** The workspace has 30+ external crate dependencies including heavy ones: `tch` (PyTorch FFI), `ort` (ONNX Runtime), `ndarray-linalg` with `openblas-static`, and 7 `ruvector-*` crates from crates.io. The `ruvector` dependency comment notes "Vendored at v2.1.0 in vendor/ruvector; using crates.io versions until published" -- suggesting a version mismatch risk between vendored and published code.
**Risk: MEDIUM**
- `ort = "2.0.0-rc.11"` is a release candidate. RC dependencies in production code carry API stability risk.
- `ndarray-linalg` with `openblas-static` forces a specific BLAS implementation that may conflict on certain platforms (ARM, WASM).
- The `tch-backend` feature flag gates the entire training pipeline. If a developer enables it without libtorch installed, the build fails without a clear error path.
**Test Ideas:**
| # | Priority | Test Idea | Automation |
|---|----------|-----------|------------|
| S-05 | P1 | Run `cargo audit` to detect known vulnerabilities in the 30+ dependencies, particularly `ort` RC and `tch` FFI bindings | CI/Unit |
| S-06 | P2 | Build the workspace on ARM64 (aarch64-unknown-linux-gnu) to confirm `openblas-static` compiles; the current CI only runs x86_64 | Integration |
| S-07 | P2 | Toggle `tch-backend` feature on `wifi-densepose-train` without libtorch installed; confirm error message is actionable, not a cryptic linker failure | Human Exploration |
#### S3: Non-Executable Files
**Finding:** 43+ ADR documents, proof data files (`sample_csi_data.json`, `expected_features.sha256`), NVS configuration files for ESP32. The proof-of-reality system uses a published SHA-256 hash of pipeline output as a trust anchor.
**Risk: LOW**
- The `expected_features.sha256` file is the single point of truth for pipeline integrity. If it is regenerated incorrectly (e.g., with a different numpy version), the proof becomes meaningless.
**Test Ideas:**
| # | Priority | Test Idea | Automation |
|---|----------|-----------|------------|
| S-08 | P0 | Run `python archive/v1/data/proof/verify.py` in CI on every PR that touches `archive/v1/src/core/` or `archive/v1/src/hardware/` to catch proof-breaking changes | CI |
| S-09 | P2 | Pin numpy/scipy versions in requirements.txt and confirm `verify.py --generate-hash` produces the same hash across Python 3.10, 3.11, and 3.12 | Integration |
---
## F -- Function
### What the product DOES
#### F1: Application -- Core Capabilities
**Finding:** The system advertises five core capabilities:
1. CSI extraction from ESP32 hardware
2. Signal processing (noise removal, phase sanitization, feature extraction, Doppler)
3. Human presence detection and pose estimation (17-keypoint COCO format)
4. Vital signs extraction (breathing rate, heart rate)
5. Mass casualty assessment (survivor detection through debris)
The Python v1 CSI processor (`csi_processor.py`) implements a complete pipeline from raw CSI frames through feature extraction to human detection. The Rust port replicates and extends this with 14 RuvSense modules for multistatic sensing.
**Risk: HIGH**
- The human detection confidence calculation in `_calculate_detection_confidence` uses hardcoded binary thresholds (`> 0.1`, `> 0.05`, `> 0.3`) with fixed weights (`0.4`, `0.3`, `0.3`). These are not calibrated against ground truth data.
- The temporal smoothing factor (`smoothing_factor = 0.9`) means the system takes ~10 frames to respond to a presence change. For a 20 Hz system, that is 500ms of latency injected by design -- acceptable for presence but too slow for pose tracking.
- The `EnsembleClassifier` in the MAT crate combines breathing, heartbeat, and movement classifiers but there are no integration tests validating that the ensemble confidence actually correlates with real survivor detection.
**Test Ideas:**
| # | Priority | Test Idea | Automation |
|---|----------|-----------|------------|
| F-01 | P0 | Feed 100 known-good CSI frames (from `sample_csi_data.json`) through the full Python pipeline and assert detection confidence is within expected range (0.7-0.95 for human-present frames) | Unit |
| F-02 | P0 | Feed 100 CSI frames of background noise (no human present) and confirm detection confidence stays below threshold (< 0.3); false positive rate must be < 5% | Unit |
| F-03 | P1 | Measure temporal smoothing convergence: inject a step change from no-human to human-present and count frames until confidence exceeds threshold; assert < 15 frames at 20 Hz | Unit |
| F-04 | P1 | Run the MAT `EnsembleClassifier` with synthetic vital signs at confidence boundary (0.49, 0.50, 0.51) and confirm correct accept/reject behavior at the `confidence_threshold` boundary | Unit |
| F-05 | P2 | Inject CSI data with `amplitudes.len() != phases.len()` into `DisasterResponse::push_csi_data` and confirm the error path returns `MatError::Detection` with descriptive message | Unit |
#### F2: Calculation Accuracy
**Finding:** The signal processing pipeline involves FFT (via `rustfft` and `scipy.fft`), correlation matrices, bandpass filtering, zero-crossing analysis, autocorrelation, and SVD decomposition. These are numerically sensitive operations.
**Risk: HIGH**
- The Doppler extraction in Python uses `scipy.fft.fft` with `n=64` bins on a sliding window of cached phase values. The normalization divides by `max_val` which can amplify noise when the max is near zero.
- The vital signs extractor (`BreathingExtractor`, `HeartRateExtractor`) uses bandpass filtering in specific Hz ranges (0.1-0.5 Hz for breathing, 0.8-2.0 Hz for heart rate). These filter boundaries are physiologically reasonable but have no tolerance handling for edge cases (e.g., athlete with 40 bpm resting heart rate = 0.67 Hz, below the 0.8 Hz lower bound).
**Test Ideas:**
| # | Priority | Test Idea | Automation |
|---|----------|-----------|------------|
| F-06 | P0 | Generate a synthetic CSI signal with known Doppler shift (e.g., 2 Hz sinusoidal phase modulation) and confirm the Doppler extraction peak is within +/- 0.5 Hz of the injected frequency | Unit |
| F-07 | P1 | Feed the `HeartRateExtractor` a signal at 0.67 Hz (40 bpm, athletic resting rate) and confirm it is either detected correctly or reported as `VitalEstimate::unavailable` -- not misclassified as breathing | Unit |
| F-08 | P1 | Test Doppler normalization edge case: when `max_val` approaches zero (< 1e-12), confirm division does not produce NaN or Inf values | Unit |
| F-09 | P2 | Compare Python `scipy.fft.fft` output against Rust `rustfft` output for the same 64-element input vector; assert difference < 1e-6 per bin | Integration |
#### F3: Error Handling
**Finding:** The Rust crates use `thiserror` with per-crate error enums (`MatError`, `SignalError`, `RuvSenseError`) that chain properly. The Python code uses custom exception classes (`CSIProcessingError`, `DatabaseConnectionError`). Both handle errors with descriptive messages.
**Risk: MEDIUM**
- The Python `CSIProcessor.process_csi_data` catches all exceptions with a blanket `except Exception as e` and wraps them in `CSIProcessingError`. This loses the original exception type and stack trace from the caller's perspective.
- The Rust `scan_cycle` method silently discards event store errors with `let _ = self.event_store.append(...)`. In a disaster response context, losing domain events could mean missing survivor detections.
**Test Ideas:**
| # | Priority | Test Idea | Automation |
|---|----------|-----------|------------|
| F-10 | P1 | Make the `InMemoryEventStore` return an error on `append()` and confirm `scan_cycle` either propagates the error or logs it at WARN+ level -- not silently discard it | Unit |
| F-11 | P2 | Inject a `numpy.linalg.LinAlgError` in the correlation matrix computation and confirm the error chain preserves the original exception type through `CSIProcessingError` | Unit |
#### F4: Security
**Finding:** The Python API implements authentication middleware (`AuthMiddleware`), rate limiting (`RateLimitMiddleware`), CORS configuration, and trusted host middleware for production. Settings require a `secret_key` field. The dev config endpoint redacts sensitive fields containing "secret", "password", "token", "key", "credential", "auth".
**Risk: MEDIUM**
- The `secret_key` field uses `Field(...)` (required) but there is no validation on minimum key length or entropy.
- CORS defaults to `["*"]` which is permissive. While overridable, the default is risky if deployed without configuration.
- The readiness check at `/health/ready` hardcodes `ready = True` with a comment "Basic readiness - API is responding" and `checks["hardware_ready"] = True` regardless of actual hardware state. This defeats the purpose of a readiness probe.
**Test Ideas:**
| # | Priority | Test Idea | Automation |
|---|----------|-----------|------------|
| F-12 | P0 | Set `secret_key` to a 3-character string and confirm the application either rejects it at startup or logs a security warning | Unit |
| F-13 | P1 | Submit a request to `/health/ready` when `pose_service` is `None` and confirm `ready` is reported as `False`, not hardcoded `True` | Integration |
| F-14 | P1 | Set `environment=production` and confirm `/docs`, `/redoc`, and `/openapi.json` endpoints return 404, not the Swagger UI | E2E |
| F-15 | P2 | Send 101 requests within the rate limit window and confirm the 101st is rejected with HTTP 429 | Integration |
#### F5: State Transitions
**Finding:** The system has multiple state machines:
- `DeviceStatus`: ACTIVE -> INACTIVE -> MAINTENANCE -> ERROR
- `SessionStatus`: ACTIVE -> COMPLETED / FAILED / CANCELLED
- `ProcessingStatus`: PENDING -> PROCESSING -> COMPLETED / FAILED
- ESP32 firmware: WiFi connecting -> connected -> CSI streaming
- RuvSense `TrackLifecycleState`: lifecycle for pose tracks
- MAT `ZoneStatus`: Active scan zones
**Risk: MEDIUM**
- The database models define valid states via `CheckConstraint` but do not enforce transition rules (e.g., can a device go from ERROR directly to ACTIVE without going through MAINTENANCE?).
**Test Ideas:**
| # | Priority | Test Idea | Automation |
|---|----------|-----------|------------|
| F-16 | P1 | Attempt to transition `DeviceStatus` from ERROR to ACTIVE directly and confirm the system either prevents it or logs the anomaly | Unit |
| F-17 | P2 | Simulate a `Session` that is in COMPLETED status and attempt to add new CSI data to it; confirm it is rejected | Unit |
---
## D -- Data
### What the product PROCESSES
#### D1: Input Data
**Finding:** The system ingests CSI frames from multiple sources:
- ESP32 ADR-018 binary protocol (UDP)
- Serial port data via `serialport` crate
- Sample JSON data (`sample_csi_data.json` with 1,000 synthetic frames)
- `CsiData` Python dataclass: amplitude (ndarray), phase (ndarray), frequency, bandwidth, num_subcarriers, num_antennas, snr, metadata
The Rust `Esp32CsiParser::parse_frame` takes raw bytes and returns structured `CsiFrame` with amplitude/phase arrays.
**Risk: MEDIUM**
- The Python `CSIData` dataclass accepts arbitrary-shaped numpy arrays for amplitude and phase. There is no validation that `amplitude.shape == (num_antennas, num_subcarriers)`.
- The ESP32 parser returns `ParseError::InsufficientData { needed, got }` but there is no handling for malformed data that has the right length but corrupt content (e.g., all-zero subcarrier data).
**Test Ideas:**
| # | Priority | Test Idea | Automation |
|---|----------|-----------|------------|
| D-01 | P1 | Create a `CSIData` with `amplitude.shape = (3, 64)` but `num_antennas = 2` and confirm the processor rejects or reshapes it | Unit |
| D-02 | P1 | Feed the ESP32 parser a correctly-sized but all-zero byte buffer and confirm it either rejects the frame (quality check) or marks `quality_score` as degraded | Unit |
| D-03 | P2 | Feed the ESP32 parser a buffer with valid header but truncated subcarrier data; confirm `ParseError::InsufficientData` | Unit |
| D-04 | P2 | Test boundary: exactly 256 subcarriers (MAX_SUBCARRIERS constant) and 257 subcarriers -- confirm correct handling | Unit |
#### D2: Data Persistence
**Finding:** The Python v1 uses SQLAlchemy with PostgreSQL (primary) and SQLite (failsafe fallback). The database schema includes 6 tables: `devices`, `sessions`, `csi_data`, `pose_detections`, `system_metrics`, `audit_logs`. The `csi_data` table stores amplitude and phase as `FloatArray` columns with a unique constraint on `(device_id, sequence_number, timestamp_ns)`.
**Risk: MEDIUM**
- Storing raw CSI amplitude/phase arrays as database columns (FloatArray) is expensive. At 20 Hz with 56 subcarriers, that is 2,240 floats/second per device stored to PostgreSQL. No data retention policy or archival strategy is documented.
- The SQLite fallback uses `NullPool` which means no connection reuse. Under load, this could exhaust file handles.
- The `audit_logs` table tracks changes but there is no mention of log rotation or size limits.
**Test Ideas:**
| # | Priority | Test Idea | Automation |
|---|----------|-----------|------------|
| D-05 | P1 | Insert 100,000 CSI frames (simulating ~83 minutes of data at 20 Hz) into the database and measure query performance for time-range retrievals | Integration |
| D-06 | P1 | Trigger PostgreSQL failover to SQLite and confirm: (a) no data loss during transition, (b) API continues responding, (c) health endpoint reports "degraded" not "healthy" | Integration |
| D-07 | P2 | Insert CSI data with duplicate `(device_id, sequence_number, timestamp_ns)` and confirm the unique constraint fires with an appropriate error message | Unit |
| D-08 | P3 | Run 1,000 concurrent SQLite connections via the NullPool fallback and monitor for "database is locked" errors | Integration |
#### D3: Proof Data Integrity
**Finding:** The proof-of-reality system (`archive/v1/data/proof/verify.py`) is a deterministic pipeline verification tool. It feeds 1,000 synthetic CSI frames through the production CSI processor, hashes the output with SHA-256, and compares against a published hash. This is a strong engineering practice.
**Risk: LOW**
- The proof only exercises the Python v1 pipeline. The Rust port has no equivalent proof-of-reality check.
- The proof uses `seed=42` for synthetic data generation. If `numpy.random` changes its RNG implementation across versions, the proof breaks without any pipeline code change.
**Test Ideas:**
| # | Priority | Test Idea | Automation |
|---|----------|-----------|------------|
| D-09 | P0 | Run `verify.py` with `--audit` flag to scan for mock/random patterns in the codebase that could compromise pipeline integrity | CI |
| D-10 | P1 | Create an equivalent proof-of-reality test for the Rust `wifi-densepose-signal` crate: feed the same 1,000 frames through `CsiProcessor::new(config)` and assert deterministic output | Unit |
---
## I -- Interfaces
### How the product CONNECTS
#### I1: REST API
**Finding:** The Python v1 exposes a FastAPI application with three router groups:
- `/health/*` -- Health, readiness, liveness, metrics, version (5 endpoints)
- `/api/v1/pose/*` -- Pose estimation endpoints
- `/api/v1/stream/*` -- Streaming endpoints
The Rust `wifi-densepose-api` crate is a 1-line stub. The `wifi-densepose-mat` crate has its own `api` module with an Axum router (`create_router, AppState`).
**Risk: HIGH**
- Two separate API implementations (Python FastAPI for v1, Rust Axum for MAT) with no shared contract or OpenAPI schema. A consumer cannot rely on interface consistency.
- The Python API's general exception handler returns a generic "Internal server error" for all unhandled exceptions in production, but logs the full traceback. If logs are not monitored, 500 errors go unnoticed.
- No API versioning enforcement: the prefix is configurable via `settings.api_prefix` but defaults to `/api/v1`. There is no v2 migration path documented.
**Test Ideas:**
| # | Priority | Test Idea | Automation |
|---|----------|-----------|------------|
| I-01 | P0 | Export OpenAPI spec from the Python FastAPI app and validate it against the actual endpoint behavior using Schemathesis or Dredd | E2E |
| I-02 | P1 | Send malformed JSON to every POST endpoint and confirm each returns HTTP 422 with validation error details, not 500 | Integration |
| I-03 | P1 | Hit the MAT Axum API and the Python FastAPI health endpoints in parallel and confirm they use compatible response schemas | Integration |
| I-04 | P2 | Send a request with `Content-Type: text/xml` to a JSON endpoint and confirm HTTP 415 Unsupported Media Type, not a 500 crash | Integration |
#### I2: WebSocket Protocol
**Finding:** The Python v1 has a WebSocket subsystem (`connection_manager.py`, `pose_stream.py`) for real-time pose data streaming. The connection manager tracks active connections and provides stats.
**Risk: MEDIUM**
- No WebSocket protocol specification (message format, heartbeat interval, reconnection policy).
- The `connection_manager.shutdown()` is called during cleanup but there is no graceful disconnect message sent to connected clients.
**Test Ideas:**
| # | Priority | Test Idea | Automation |
|---|----------|-----------|------------|
| I-05 | P1 | Connect 100 WebSocket clients simultaneously and confirm: (a) all receive pose data, (b) connection stats are accurate, (c) no memory leak over 60 seconds | Integration |
| I-06 | P1 | Disconnect a WebSocket client abruptly (TCP reset) and confirm the server cleans up the connection without leaking resources | Integration |
| I-07 | P2 | Send a malformed message over WebSocket and confirm the server rejects it without disconnecting the client | Integration |
#### I3: ESP32 Serial/UDP Protocol
**Finding:** The ESP32 firmware uses ADR-018 binary format for CSI frames sent over UDP. The firmware includes WiFi reconnection logic with exponential retry (up to MAX_RETRY=10), NVS configuration persistence, OTA update capability, and WASM runtime support.
The Rust `Esp32CsiParser` parses the binary frames from UDP bytes.
**Risk: HIGH**
- The ADR-018 binary protocol has no version field visible in the main.c header. If the protocol format changes, there is no way for the receiver to detect version mismatch.
- The UDP transport is fire-and-forget. There is no acknowledgment, no sequence gap detection documented in the receiver, and no backpressure mechanism.
- The `stream_sender.c` sends to a hardcoded or NVS-configured target IP. If the aggregator moves, the sensor is stranded until re-provisioned.
**Test Ideas:**
| # | Priority | Test Idea | Automation |
|---|----------|-----------|------------|
| I-08 | P0 | Inject a CSI frame with a future/unknown protocol version byte and confirm the parser returns `ParseError` with a version mismatch message, not a crash | Unit |
| I-09 | P1 | Send 1,000 UDP CSI frames at 20 Hz from a simulated ESP32 and measure packet loss rate at the aggregator; assert < 1% loss on loopback | Integration |
| I-10 | P1 | Simulate network partition: stop sending UDP frames for 5 seconds, then resume. Confirm the aggregator recovers without manual intervention | Integration |
| I-11 | P2 | Send a UDP frame from a spoofed MAC address and confirm the aggregator either rejects or flags it (ADR-032 security hardening) | Integration |
#### I4: Inter-Crate Boundaries (Rust)
**Finding:** The Rust workspace has clear crate boundaries with `pub use` re-exports. The core traits (`SignalProcessor`, `NeuralInference`, `DataStore`) define contracts. However, some inter-crate communication uses concrete types rather than trait objects.
**Risk: MEDIUM**
- `wifi-densepose-mat` depends on `wifi-densepose-signal::SignalError` directly via `#[from]`. This couples the MAT error hierarchy to Signal internals.
- The `wifi-densepose-train` crate conditionally compiles 5 modules (`losses`, `metrics`, `model`, `proof`, `trainer`) behind the `tch-backend` feature. This means the training crate's public API surface changes dramatically based on feature flags.
**Test Ideas:**
| # | Priority | Test Idea | Automation |
|---|----------|-----------|------------|
| I-12 | P1 | Build `wifi-densepose-mat` with `wifi-densepose-signal` at a different version (e.g., mock a breaking change in `SignalError`) and confirm the type error is caught at compile time | Unit |
| I-13 | P2 | Compile `wifi-densepose-train` with and without `tch-backend` and diff the public API symbols; document the feature-gated surface area | Integration |
#### I5: CLI Interface
**Finding:** The Rust CLI (`wifi-densepose-cli`) provides subcommands for MAT operations: `mat scan`, `mat status`, `mat survivors`, `mat alerts`. Built with `clap` derive macros.
**Risk: LOW**
- CLI is narrowly scoped to MAT operations. No CLI for CSI data capture, signal processing, or model training.
**Test Ideas:**
| # | Priority | Test Idea | Automation |
|---|----------|-----------|------------|
| I-14 | P2 | Run `wifi-densepose --help`, `wifi-densepose mat --help`, and confirm all documented subcommands are present and help text is accurate | E2E |
| I-15 | P3 | Run `wifi-densepose mat scan --zone ""` (empty zone name) and confirm a user-friendly error, not a panic | Unit |
---
## P -- Platform
### What the product DEPENDS ON
#### P1: Multi-Platform Build Targets
**Finding:** The project targets 6 platforms:
1. **Linux x86_64** -- Primary development/server platform (CI runs here)
2. **Windows** -- ESP32 firmware build requires special MSYSTEM env var stripping
3. **macOS** -- CoreWLAN WiFi sensing (ADR-025), `mac_wifi.swift` in sensing module
4. **ESP32-S3** -- Xtensa dual-core, 8MB/4MB flash variants
5. **WASM (wasm32-unknown-unknown)** -- Browser deployment via wasm-pack
6. **Desktop** -- `wifi-densepose-desktop` crate (52 lines in lib.rs, minimal)
Explicitly unsupported: ESP32 (original) and ESP32-C3 (single-core, cannot run DSP pipeline).
**Risk: HIGH**
- The CI workflow (`ci.yml`) only runs on `ubuntu-latest`. No Windows, macOS, or ARM64 CI jobs for the Rust crates.
- The macOS CoreWLAN integration (`mac_wifi.swift`) exists in the Python sensing module but there are no tests or build validation for it.
- The `openblas-static` dependency in `ndarray-linalg` does not compile on `wasm32-unknown-unknown`, yet `wifi-densepose-signal` depends on it. This means any crate depending on `signal` cannot target WASM without feature gating.
- The firmware CI (`firmware-ci.yml`, `firmware-qemu.yml`) exists but the `verify-pipeline.yml` suggests a separate verification path.
**Test Ideas:**
| # | Priority | Test Idea | Automation |
|---|----------|-----------|------------|
| P-01 | P0 | Add macOS and Windows CI runners for `cargo test --workspace --no-default-features` to catch platform-specific compilation failures | CI |
| P-02 | P1 | Build `wifi-densepose-wasm` with `wasm-pack build --target web` in CI and confirm it produces a valid `.wasm` binary under 5 MB | CI |
| P-03 | P1 | Flash the 4MB firmware variant to an ESP32-S3 and confirm it boots, connects to WiFi, and streams CSI frames within 30 seconds | Hardware/Human |
| P-04 | P2 | Attempt to build the firmware for ESP32 (original, non-S3) and confirm the build fails with a clear error message about single-core incompatibility | Integration |
#### P2: External Software Dependencies
**Finding:** The system depends on:
- PostgreSQL (primary database)
- Redis (caching, rate limiting -- optional)
- libtorch (PyTorch C++ backend -- optional via `tch-backend` feature)
- ONNX Runtime (`ort` crate)
- OpenBLAS (via `ndarray-linalg`)
- ESP-IDF v5.4 (firmware toolchain)
- wasm-pack (WASM build tool)
**Risk: MEDIUM**
- The PostgreSQL-to-SQLite failsafe is a good design but the SQLite fallback does not support all PostgreSQL features (e.g., `UUID` columns, array types via `StringArray`/`FloatArray`). The `model_types.py` file likely provides compatibility shims but this is an untested assumption.
- Redis is marked optional but the `RateLimitMiddleware` likely depends on it for distributed rate limiting. If Redis is down and rate limiting is enabled, what happens?
**Test Ideas:**
| # | Priority | Test Idea | Automation |
|---|----------|-----------|------------|
| P-05 | P1 | Start the API with `redis_enabled=True` but Redis unavailable, and `redis_required=False`. Confirm the API starts, rate limiting degrades gracefully, and health reports "degraded" | Integration |
| P-06 | P1 | Insert a `Device` record via SQLite fallback with a UUID primary key and StringArray capabilities column; confirm round-trip read matches the write | Integration |
| P-07 | P2 | Run the full Python test suite on Python 3.12 (the CI uses 3.11) to catch forward-compatibility issues | CI |
#### P3: Hardware Compatibility
**Finding:** Supported hardware:
- ESP32-S3 (8MB flash) at ~$9
- ESP32-S3 SuperMini (4MB flash) at ~$6
- ESP32-C6 + Seeed MR60BHA2 (60 GHz FMCW mmWave) at ~$15
- HLK-LD2410 (24 GHz FMCW presence sensor) at ~$3
The ESP32-S3 is the primary sensing node. The mmWave sensors are auxiliary.
**Risk: MEDIUM**
- The 4MB flash variant (`sdkconfig.defaults.4mb`) may not have room for OTA + WASM runtime + display driver. Partition table conflicts are plausible but not tested in CI.
- The mmWave sensor integration (`mmwave_sensor.c`) exists in firmware but there are no tests validating the serial protocol parsing for the MR60BHA2 radar.
**Test Ideas:**
| # | Priority | Test Idea | Automation |
|---|----------|-----------|------------|
| P-08 | P1 | Build 4MB firmware with OTA + WASM + display all enabled and confirm the binary fits within the 4MB flash partition | CI |
| P-09 | P2 | Send synthetic MR60BHA2 serial output to the `mmwave_sensor.c` parser and confirm correct heart rate / breathing rate extraction | Unit |
---
## O -- Operations
### How the product is USED
#### O1: Deployment Model
**Finding:** No Dockerfile exists (only `.dockerignore`). CI includes `cd.yml` (continuous deployment) but deployment target is unknown. The firmware has a documented flash process using `idf.py` and a provisioning script (`provision.py`).
**Risk: HIGH**
- Without a Dockerfile, the Python v1 API has no standardized deployment. Server setup is manual and environment-specific.
- The firmware OTA update mechanism (`ota_update.c`) exists but the end-to-end update path (build -> sign -> distribute -> apply -> verify) is undocumented.
- No Kubernetes manifests, systemd service files, or other deployment automation.
**Test Ideas:**
| # | Priority | Test Idea | Automation |
|---|----------|-----------|------------|
| O-01 | P1 | Create a Docker image for the Python v1 API and confirm it starts, responds to `/health/live`, and connects to a PostgreSQL container | Integration |
| O-02 | P1 | Test the firmware OTA path: build a new firmware image, host it on HTTP, trigger OTA from the device, and confirm the device reboots with the new version | Hardware/Human |
| O-03 | P2 | Run `wifi-densepose mat scan` on a freshly provisioned ESP32-S3 and confirm end-to-end data flow from sensor to CLI output | E2E/Human |
#### O2: Monitoring and Observability
**Finding:** The Python API provides comprehensive health checks (`/health/health`, `/health/ready`, `/health/live`), system metrics (CPU, memory, disk, network via `psutil`), and per-component health status. The Rust crates use `tracing` for structured logging.
**Risk: MEDIUM**
- The health check calls `psutil.cpu_percent(interval=1)` which blocks for 1 second. This makes the health endpoint slow and potentially a bottleneck under load.
- The system metrics endpoint is available to unauthenticated users at `/health/metrics`. Only "detailed metrics" require authentication.
- There is no distributed tracing (e.g., OpenTelemetry) for correlating requests across the Python API, ESP32 firmware, and potential Rust services.
**Test Ideas:**
| # | Priority | Test Idea | Automation |
|---|----------|-----------|------------|
| O-04 | P1 | Call `/health/health` 10 times concurrently and confirm total response time is < 15 seconds (not 10x the 1-second cpu_percent block) | Integration |
| O-05 | P2 | Confirm `/health/metrics` does not expose PII, database credentials, or internal IP addresses in the response body | Security/E2E |
#### O3: User Workflows
**Finding:** Primary user workflows:
1. Researcher: Configure sensors -> Collect CSI data -> Train model -> Evaluate
2. Disaster responder: Deploy sensors -> Start MAT scan -> Monitor survivors -> Triage
3. Developer: Clone repo -> Build -> Run tests -> Submit PR
**Risk: MEDIUM**
- The disaster responder workflow is safety-critical. A false negative (missing a survivor) has life-or-death consequences. The system should have explicit false negative rate metrics but none are defined.
- The developer workflow requires installing OpenBLAS, potentially libtorch, and ESP-IDF v5.4. No `devcontainer.json` or `nix-shell` to standardize the development environment.
**Test Ideas:**
| # | Priority | Test Idea | Automation |
|---|----------|-----------|------------|
| O-06 | P0 | Run the complete developer setup workflow from a clean Ubuntu 22.04 VM: clone, install deps, `cargo test --workspace --no-default-features`, `python archive/v1/data/proof/verify.py` -- measure total setup time and document any manual steps | Human Exploration |
| O-07 | P1 | Simulate a MAT scan with 5 survivors at varying signal strengths (strong, weak, borderline) and confirm the triage classification matches expected START protocol categories | Integration |
#### O4: Extreme Use
**Finding:** No load testing, stress testing, or chaos engineering infrastructure exists.
**Risk: HIGH**
- The system targets disaster response scenarios where multiple ESP32 nodes stream simultaneously. The aggregator's behavior under 10+ concurrent node streams is unknown.
- The database writes CSI data at 20 Hz per device. With 10 devices, that is 200 inserts/second of array data into PostgreSQL.
**Test Ideas:**
| # | Priority | Test Idea | Automation |
|---|----------|-----------|------------|
| O-08 | P1 | Simulate 10 ESP32 nodes streaming at 20 Hz to the aggregator and measure: packet loss, processing latency per frame, memory growth over 5 minutes | Performance |
| O-09 | P2 | Fill the CSI history deque to `max_history_size=500` and confirm the oldest entry is evicted, not causing an OOM | Unit |
---
## T -- Time
### WHEN things happen
#### T1: Real-Time Processing
**Finding:** The RuvSense pipeline targets 20 Hz output (50ms per TDMA cycle). The vital signs extraction uses sample rates of 100 Hz with 30-second windows. The CSI processor uses configurable `sampling_rate`, `window_size`, and `overlap`.
**Risk: CRITICAL**
- No latency benchmarks exist anywhere in the codebase. The 20 Hz target implies each frame must be processed in < 50ms including multi-band fusion, phase alignment, multistatic fusion, coherence gating, and pose tracking. This budget has never been measured.
- The Python `process_csi_data` method is `async` but all the numpy operations inside are synchronous and CPU-bound. The `await` is cosmetic -- it does not yield to the event loop during computation.
- The Doppler extraction iterates over the phase cache on every call. With `max_history_size=500`, this means constructing a 500-element numpy array from a deque on each frame.
**Test Ideas:**
| # | Priority | Test Idea | Automation |
|---|----------|-----------|------------|
| T-01 | P0 | Benchmark the Rust `RuvSensePipeline` end-to-end latency for a single frame with 4 nodes and 56 subcarriers; assert total processing time < 50ms on x86_64 | Benchmark |
| T-02 | P0 | Benchmark the Python `CSIProcessor.process_csi_data` method for a single frame and assert it completes in < 25ms (leaving budget for I/O and networking) | Benchmark |
| T-03 | P1 | Profile the Doppler extraction path with `max_history_size=500`: measure time spent in `list(self._phase_cache)` and `np.array(cache_list[-window:])` | Benchmark |
| T-04 | P1 | Run the Python CSI processor with `asyncio.run()` and confirm it does not block the event loop for > 10ms per frame; use `asyncio.get_event_loop().slow_callback_duration` | Integration |
#### T2: Concurrency
**Finding:** The Rust system uses `tokio` for async runtime with `features = ["full"]`. The Python API uses FastAPI (async) with uvicorn workers. The ESP32 firmware uses FreeRTOS tasks. The `DisasterResponse::running` flag uses `AtomicBool` for thread-safe scanning control.
**Risk: HIGH**
- The `DisasterResponse` struct is not `Send + Sync` safe by default (it contains `dyn EventStore` behind an `Arc`, but the struct itself is not wrapped in a `Mutex`). If `start_scanning` is called from multiple threads, the mutable self-reference causes a data race.
- The Python `get_database_manager` uses a module-level global `_db_manager` with no thread-safety protection. With multiple uvicorn workers, each worker gets its own instance (process isolation), but within a single worker, concurrent requests could race on initialization.
- The ESP32 firmware uses FreeRTOS event groups for WiFi state but the CSI callback runs in the WiFi driver context. If the callback takes too long (e.g., edge processing), it blocks WiFi reception.
**Test Ideas:**
| # | Priority | Test Idea | Automation |
|---|----------|-----------|------------|
| T-05 | P0 | Run `cargo test` under Miri (or ThreadSanitizer) for the `wifi-densepose-mat` crate to detect data races in `DisasterResponse` | CI |
| T-06 | P1 | Call `DatabaseManager.initialize()` concurrently from 10 async tasks and confirm only one initialization occurs (no double-init race) | Integration |
| T-07 | P1 | Measure the CSI callback execution time on ESP32 and confirm it completes in < 1ms to avoid blocking the WiFi driver | Hardware/Benchmark |
| T-08 | P2 | Start and stop `DisasterResponse::start_scanning` from two different tokio tasks simultaneously and confirm no panic or deadlock | Unit |
#### T3: Scheduling and Timeouts
**Finding:** The MAT scan interval is configurable (`scan_interval_ms`, default 500ms, minimum 100ms). The database connection pool has `pool_timeout=30s` and `pool_recycle=3600s`. Redis has `socket_timeout=5s` and `connect_timeout=5s`.
**Risk: MEDIUM**
- The ESP32 WiFi reconnection has `MAX_RETRY=10` but no backoff strategy. Ten rapid reconnection attempts could flood the AP.
- No timeout on the `scan_cycle` method itself. If detection takes longer than `scan_interval_ms`, cycles overlap without back-pressure.
- The `pool_recycle=3600` means database connections are recycled every hour. In a long-running deployment, this causes periodic connection churn.
**Test Ideas:**
| # | Priority | Test Idea | Automation |
|---|----------|-----------|------------|
| T-09 | P1 | Set `scan_interval_ms=100` (minimum) and run a scan cycle that takes 200ms to complete; confirm the system does not accumulate a backlog of overlapping cycles | Unit |
| T-10 | P2 | Simulate 10 WiFi disconnects in rapid succession on ESP32 and confirm the retry counter increments correctly and stops at MAX_RETRY=10 | Integration/Hardware |
| T-11 | P2 | Keep the API running for 2 hours and confirm database pool recycling does not cause request failures during connection rotation | Integration |

## Suggestions for Exploratory Test Sessions
### Exploratory Test Sessions: Structure
1. **Session: Crate Dependency Graph Walk** -- Starting from `wifi-densepose-cli`, trace every transitive dependency and look for diamond dependencies, version conflicts, or unnecessary coupling between crates that should be independent.
2. **Session: Feature Flag Combinatorics** -- Systematically toggle feature flags on `wifi-densepose-train` (tch-backend on/off) and `wifi-densepose-core` (std/serde/async) and build each combination. Look for compilation failures, missing exports, or confusing error messages.
### Exploratory Test Sessions: Function
3. **Session: Detection Confidence Calibration** -- Feed the CSI processor a sequence of frames that transitions from empty room to one person to two people. Observe how the confidence score evolves. Look for oscillation, slow convergence, or failure to distinguish scenarios.
4. **Session: MAT Disaster Scenario Walkthrough** -- Set up a full MAT scan with 3 zones, inject synthetic CSI data representing 5 survivors at varying depths (0.5m, 2m, 5m). Observe triage classification, alert generation, and event store entries. Look for missing events or incorrect triage.
### Exploratory Test Sessions: Data
5. **Session: Database Failover Chaos** -- Start the API with PostgreSQL, insert data, kill PostgreSQL, observe failover to SQLite, insert more data, restart PostgreSQL, and examine whether the system recovers. Look for data loss, schema incompatibilities, or stuck states.
6. **Session: Proof of Reality Deep Dive** -- Run `verify.py --verbose` and `verify.py --audit` on a fresh checkout. Modify one line of `csi_processor.py` (e.g., change a threshold) and re-run verify. Look for how quickly the hash changes and whether the error message identifies what changed.
### Exploratory Test Sessions: Interfaces
7. **Session: API Fuzzing Marathon** -- Use `schemathesis` or `restler` against the running FastAPI application for 30 minutes. Focus on edge cases: empty bodies, huge payloads (10 MB JSON), unicode in string fields, negative numbers in integer fields. Track every 500 response.
8. **Session: ESP32 Protocol Mismatch Hunt** -- Capture real UDP traffic from an ESP32-S3, modify bytes at various offsets, and feed them to the `Esp32CsiParser`. Look for panics, undefined behavior, or incorrect but accepted frames.
### Exploratory Test Sessions: Platform
9. **Session: macOS CoreWLAN Availability** -- On a macOS machine, attempt to use the `mac_wifi.swift` sensing module. Look for compilation issues, missing entitlements, or WiFi permission dialogs that block unattended operation.
10. **Session: WASM in Browser** -- Build `wifi-densepose-wasm` and load it in Chrome, Firefox, and Safari. Call `MatDashboard` methods from the JavaScript console. Look for WASM memory limits, missing `web-sys` features, or browser-specific failures.
### Exploratory Test Sessions: Operations
11. **Session: First-Time Setup Experience** -- Follow the README as a new developer on a clean Ubuntu 22.04 VM. Document every step that fails, every missing dependency, and every confusing error. Measure total time from `git clone` to first passing test.
12. **Session: Firmware Provisioning End-to-End** -- Use the `provision.py` script to configure a real ESP32-S3 with WiFi credentials. Monitor serial output. Disconnect and reconnect. Look for edge cases in NVS persistence, WiFi credential storage, and recovery from bad configuration.
### Exploratory Test Sessions: Time
13. **Session: Latency Budget Profiling** -- Instrument the Rust `RuvSensePipeline` with `tracing` spans on each stage (multiband, phase_align, multistatic, coherence, pose_tracker). Run 1,000 frames and produce a flame graph. Identify which stage consumes the most of the 50ms budget.
14. **Session: Concurrent Scanning Stress** -- Start `DisasterResponse::start_scanning` with `continuous_monitoring=true` and `scan_interval_ms=100`. While scanning, call `push_csi_data` from a separate thread at 200 Hz. Look for data races, queue overflow, or missed scans.
---
## Clarifying Questions
Suggestions based on general risk patterns and analysis of the existing codebase:
### Structure
1. What is the intended relationship between the Python v1 API and the Rust `wifi-densepose-api` stub? Is the Rust API planned to replace Python, or will they coexist?
2. Why is `wifi-densepose-wasm-edge` excluded from the workspace? Are its tests run in a separate CI job, or are they not run at all?
### Function
3. What is the acceptable false positive rate for human detection? What is the acceptable false negative rate for MAT survivor detection? These are not documented anywhere.
4. The `HeartRateExtractor` bandpass filter starts at 0.8 Hz (48 bpm). Is this intentional, given that athletic resting heart rates can be 40 bpm (0.67 Hz)?
5. The `smoothing_factor` of 0.9 introduces ~500ms lag at 20 Hz. Is this acceptable for the pose tracking use case, or should it be configurable per-mode?
### Data
6. What is the data retention policy for CSI frames in PostgreSQL? At 20 Hz per device, storage grows at ~2.7 GB/day per device (estimated). Who is responsible for archival?
7. Is there a plan to create a Rust-equivalent proof-of-reality test to ensure the Rust signal processing pipeline matches the Python pipeline output?
### Interfaces
8. Does the ADR-018 binary protocol include a version byte? If the firmware and server are at different protocol versions, how is this detected?
9. What is the WebSocket message format for pose data streaming? Is it documented in an ADR or schema file?
10. Is there authentication on the UDP CSI data stream, or can any device on the network inject frames into the aggregator?
### Platform
11. Is ARM64 (e.g., Raspberry Pi 4/5) a supported deployment target for the server? If so, has `openblas-static` been validated on ARM64?
12. Are there plans for an Android or iOS mobile app, or is the `wifi-densepose-desktop` crate the only non-server deployment target?
### Operations
13. Is there a Docker image on Docker Hub as mentioned in the pre-merge checklist? If so, what is the image name and how is it built?
14. What is the firmware signing process for OTA updates? Is there a code-signing key, and how is it managed?
15. Who monitors the `/health/health` endpoint in production? Is there an alerting integration (PagerDuty, Opsgenie, etc.)?
### Time
16. Has the 20 Hz (50ms per frame) latency budget ever been measured on actual hardware with real CSI data? What is the measured P99 latency?
17. What happens when `scan_cycle` takes longer than `scan_interval_ms`? Does the next cycle start immediately, or is there a backlog mechanism?
18. The ESP32 CSI callback runs in the WiFi driver context. What is the maximum allowed execution time before WiFi reception is impacted?

## Priority Summary: Top 10 Actions
1. **T-01/T-02 (P0):** Benchmark real-time processing latency against the 50ms budget. The entire system's viability depends on this.
2. **F-01/F-02 (P0):** Establish baseline false positive/negative rates for human detection with known test data.
3. **T-05 (P0):** Run ThreadSanitizer on the MAT crate to detect data races in the multi-threaded scanning path.
4. **P-01 (P0):** Add macOS and Windows CI runners. A 6-platform project tested on 1 platform is a risk multiplier.
5. **I-08 (P0):** Add protocol version detection to the ESP32 parser to prevent silent data corruption from version mismatches.
6. **S-08/D-09 (P0):** Ensure proof-of-reality runs on every PR touching the signal processing pipeline.
7. **F-12 (P0):** Validate that weak secrets are rejected at startup, not silently accepted.
8. **O-06 (P0):** Document and automate the developer setup experience. A system this complex needs reproducible environments.
9. **F-04 (P1):** Test MAT ensemble classifier at confidence boundaries. In disaster response, boundary behavior determines life-or-death decisions.
10. **I-01 (P0):** Generate and validate OpenAPI contract. Two API implementations (Python + Rust) without a shared contract will inevitably diverge.

## P0 -- Fix Immediately (Security + CI)
| # | Issue | File(s) | Impact |
|---|-------|---------|--------|
| 1 | **Rate limiter bypass** -- trusts `X-Forwarded-For` without validation | `archive/v1/src/middleware/rate_limit.py:200-206` | Any client can bypass rate limits via header spoofing |
| 2 | **Exception details leaked** in HTTP responses regardless of environment | `archive/v1/src/api/routers/pose.py:140`, `stream.py:297`, +5 others | Stack traces visible to attackers |
| 3 | **WebSocket JWT in URL** -- tokens visible in logs, browser history, proxies | `archive/v1/src/api/routers/stream.py:74`, `archive/v1/src/middleware/auth.py:243` | Token exposure (CWE-598) |
| 4 | **Rust tests not in CI** -- 2,618 tests in largest codebase never run in pipeline | No `cargo test` in any GitHub Actions workflow | Regressions ship undetected |
| 5 | **WebSocket path mismatch** -- mobile app sends to wrong endpoint | `ui/mobile/src/services/ws.service.ts:104` vs `constants/websocket.ts:1` | Mobile WebSocket connections fail silently |
## P1 -- Fix This Sprint (Performance + Code Health)
| # | Issue | File(s) | Impact |
|---|-------|---------|--------|
| 6 | **God file: 4,846 lines, CC=121** -- sensing-server main.rs | `crates/wifi-densepose-sensing-server/src/main.rs` | Untestable, unmaintainable monolith |
| 7 | **O(L*V) tomography voxel scan** per frame | `ruvsense/tomography.rs:345-383` | ~10ms wasted per frame; use DDA ray march for 5-10x speedup |
| 8 | **Sequential neural inference** -- defeats GPU batching | `wifi-densepose-nn inference.rs:334-336` | 2-4x latency penalty |
| 9 | **720 `.unwrap()` calls** in Rust production code | Across entire Rust workspace | Each is a potential panic in real-time/safety-critical paths |
| 10 | **Python Doppler: 112KB alloc per frame** at 20Hz | `archive/v1/src/core/csi_processor.py:412-414` | Converts deque -> list -> numpy every frame |
## P2 -- Fix This Quarter (Coverage + Safety)
| # | Issue | File(s) | Impact |
|---|-------|---------|--------|
| 11 | **11/12 Python modules untested** -- only CSI extraction has unit tests | `archive/v1/src/services/`, `middleware/`, `database/`, `tasks/` | 12,280 LOC with zero unit tests |
| 12 | **Firmware at 19% coverage** -- WASM runtime, OTA, swarm bridge untested | `firmware/esp32-csi-node/main/wasm_runtime.c` (867 LOC) | Security-critical code with no tests |
| 13 | **MAT simulation fallback** -- disaster tool auto-falls back to simulated data | `ui/mobile/src/screens/MATScreen/index.tsx` | Risk of operators monitoring fake data during real incidents |
| 14 | **Token blacklist never consulted** during auth | `archive/v1/src/api/middleware/auth.py:246-252` | Revoked tokens remain valid |
| 15 | **50ms frame budget never benchmarked** -- no latency CI gate | No benchmark harness exists | Real-time requirement is aspirational, not verified |
## P3 -- Technical Debt
| # | Issue | Impact |
|---|-------|--------|
| 16 | 340 `unsafe` blocks need formal safety audit | Potential UB in production |
| 17 | 5 duplicate CSI extractor test files (~90 redundant tests) | Maintenance burden |
| 18 | Performance tests mock inference with `asyncio.sleep()` | Tests measure scheduling, not performance |
| 19 | CORS wildcard + credentials default | Browser security weakened |
| 20 | ESP32 UDP CSI stream unencrypted | CSI data interceptable on LAN |
