## [Unreleased]
|
||||
|
||||
### Fixed
|
||||
- **ESP32 edge heart rate no longer stuck at ~45 BPM / dropping wildly — #987.** The on-device HR estimator (`edge_processing.c`, `0xC5110002`) reported ~45 BPM regardless of true heart rate (Apple-Watch ground truth 87 BPM read as ~45) and swung frame-to-frame. Two root causes: (1) a hardcoded `sample_rate = 10.0f` that became wrong after #985's self-ping raised the CSI callback rate to a variable ~13–19 Hz — BPM scales as `assumed/actual × true`, so 87 read ~45 and the reading swung as CSI yield fluctuated; (2) the zero-crossing estimator locked onto a breathing harmonic (a 0.25 Hz breathing fundamental puts its 3rd harmonic at ~0.74 Hz ≈ 44 BPM inside the HR band). Fix: measure the real sample rate from inter-frame timestamps (used for BPM conversion + biquad re-tuning on >15% drift); replace the HR zero-crossing with an autocorrelation estimator that rejects breathing harmonics (driven by a robust autocorr breathing period); median-13 smooth the output. Hardware A/B (fixed vs unmodified control board, both `edge_tier=2`): control pegged 40–49 BPM; fixed reaches the true 88–91 BPM (vs 87 GT) and holds a stable physiological value (spread 59→0 for a steady subject). Known limitation: heavy subject motion still degrades the estimate (motion gating is a follow-up).
|
||||
- **Person count no longer leaks up to 10 in heuristic mode — addresses #894.** `field_bridge::occupancy_or_fallback` returned the eigenvalue-based `FieldModel::estimate_occupancy` count **unbounded** (its internal ceiling is 10), while the sibling estimators on the same single-link data — the perturbation-energy fallback right below it and `score_to_person_count` — both cap at 3 ("1-3 for single ESP32"). On noisy / under-calibrated CSI the eigenvalue count inflated, producing the "10 persons reported when 1 present" symptom (seen when `--model` fails to load and the server runs on heuristics). Bounded the eigenvalue path to the shared `MAX_SINGLE_LINK_OCCUPANCY` (3) so every estimator on one link agrees; genuine higher counts come from the multistatic fusion path, not a single-link covariance estimate.
|
||||
- **MQTT multi-node deployments now create one Home-Assistant device per node — closes #898.** After the #872 MQTT wiring landed, the JSON→`VitalsSnapshot` bridge hard-coded a single `node_id` (the MQTT client id) and the publisher used a single `OwnedDiscoveryBuilder`, so every physical node collapsed into one device (`identifiers:["wifi_densepose_wifi-densepose-1"]`), contradicting the "one device per node" docs. The bridge now emits one snapshot per node in the sensing update's `nodes[]` (each with its own `node_id` + RSSI, falling back to a single aggregate snapshot for wifi/simulate sources), and the publisher derives a per-node builder (`OwnedDiscoveryBuilder::for_node`) that publishes discovery + availability lazily on first sight of each `node_id` and routes state to per-node topics — yielding N distinct HA devices with per-node availability/LWT. Unit-tested (distinct nodes → distinct `wifi_densepose_<node>` identifiers); 71 MQTT tests pass.
|
||||
- **Person count no longer pinned to 1 — addresses #803.** The aggregate occupancy reported by the sensing server was derived from `smoothed_person_score`, an EMA-smoothed *activity* score (amplitude variance / motion / spectral energy). That score saturates near a single occupant — one moving person maxes it out — so it cannot discriminate occupancy *count* and stayed clamped at 1 across S3/C6 and the Python/Docker/Rust servers. Meanwhile the count-aware per-node estimates the ESP32 paths already compute (firmware `n_persons`, and the DynamicMinCut `corr_persons`) were stashed in `NodeState::prev_person_count` and then **discarded** by the aggregator (same dead-wiring class as #872). The aggregator now takes `max(activity_count, node_max)` via a unit-tested `aggregate_person_count` helper, so a node positively estimating 2–3 occupants is surfaced instead of overwritten. The fix can only ever *raise* the count when a node reports more people, so the single-occupant case is provably never inflated (regression-guarded by test). **Second half:** the pure-CSI per-node path itself clamped its own estimate — the DynamicMinCut occupancy (`estimate_persons_from_correlation`, 0–3) was mapped to a score via `corr_persons / 3.0`, putting 2 people at 0.667, *just under* the 0.70 up-threshold of `score_to_person_count`, so the per-node count never climbed past 1 (so `node_max` was also stuck at 1 for CSI-only nodes). Replaced it with a threshold-aligned `corr_persons_to_score` mapping (1→0.40, 2→0.74, 3→0.96) whose steady state round-trips back to the same count through the EMA + hysteresis, while still gating transient noise. A convergence test replays the exact EMA loop to prove min-cut=2 now reports 2 (and documents that the old `/3.0` mapping reported 1). Full multi-person accuracy still depends on the underlying estimator quality; this removes the two server-side clamps that masked it. 586 sensing-server tests pass.
|
||||
- **MQTT publisher now actually runs (`--mqtt`) — closes #872.** The `--mqtt*` flags were defined only in `cli::Args` (dead code, referenced nowhere) while the binary parses a *separate* `main::Args` with no mqtt fields, and `main.rs` never started the `mqtt::` publisher — so MQTT/Home-Assistant integration was completely unwired (`--mqtt` errored as an unexpected argument, and even with the Docker image's `--features mqtt` build the publisher never ran). Earlier attempts chased a Docker *rebuild*; the real cause was disconnected *code*. Extracted the flags into a shared `cli::MqttArgs` (`#[command(flatten)]` into both structs), spawn the publisher on `--mqtt`, and bridge the JSON sensing broadcast into the typed `VitalsSnapshot` stream with a defensive `serde_json::Value` mapping. Verified end-to-end against `mosquitto`: 20 HA auto-discovery entities + live state (presence/person-count/…). 577 (default) / 580 (`--features mqtt`) tests pass.
|
||||
- **Mass Casualty triage never reports a survivor with a heartbeat as Deceased (safety) — PR #926.** Both triage paths in `wifi-densepose-mat` — `TriageCalculator::calculate` (`combine_assessments(Absent, None) ⇒ Deceased`) and the detection path `EnsembleClassifier::determine_triage` (`!has_breathing && !has_movement ⇒ Deceased`) — ignored the `heartbeat` field. A survivor with a detectable **pulse** but no sensed breathing/movement (respiratory arrest — the most time-critical *savable* state, Immediate/Red) was therefore reported **Deceased (Black)** and deprioritized for rescue. The domain path was in fact only reachable *because* a heartbeat made `has_vitals()` true, so every "Deceased" was a live person. Both paths now escalate to **Immediate** when a heartbeat is present; total absence of breathing, movement *and* heartbeat is unchanged (domain → `Unknown`, ensemble → `Deceased`). 2 safety regression tests; full MAT suite (177) green.
|
||||
- **Per-node Home-Assistant devices now report each node's *own* presence/motion — PR #918.** After the one-device-per-node fan-out landed, the MQTT bridge still applied the *room-level aggregate* `classification` to every node, so in a multi-node deployment a node watching an empty corner inherited another node's "present" (and `motion_level: "absent"` was mis-mapped to full motion). Each node in the broadcast `nodes[]` already carries its own `classification`; the bridge now reads it per node (extracted into a testable `vitals_snapshots_from_sensing_json`), keeping vitals + person count room-level. 4 unit tests.
|
||||
- **`--model` gives an actionable diagnostic instead of a cryptic magic error — PR #919 (refs #894).** Passing a HuggingFace `ruvnet/wifi-densepose-pretrained` file (`model.safetensors` / `model-q4.bin` / `model.rvf.jsonl`) to `--model` produced `invalid magic at offset 0: … got 0x77455735`, then a silent fall back to heuristics. The load-failure path now detects the format (safetensors / quantized blob / JSONL manifest) and explains that those files are a different format **and** encoder architecture than the RVF binary container the progressive loader expects, pointing to #894. Pure `diagnose_model_load_error` + 4 tests.
|
||||
- **`--export-rvf` no longer silently produces a placeholder model — PR #920.** The `--export-rvf` handler ran *before* `--train`/`--pretrain` and unconditionally wrote placeholder sine-wave weights, so the documented `--train … --export-rvf <path>` workflow short-circuited to a fake model and never trained (while printing "exported successfully"). It now emits the placeholder **container-format demo** only standalone (with a clear warning), and falls through to real training when `--train`/`--pretrain` is set; docs point to `--save-rvf` for the real model. 3 guard tests.
|
||||
|
||||
### Added
|
||||
- **ADR-151 per-room calibration & specialist training — full `baseline → enroll → extract → train` pipeline (new `wifi-densepose-calibration` crate).** "Teach the room before you teach the model": a local-first pipeline that turns a few minutes of clean human anchors — layered on the ADR-135 empty-room baseline — into a versioned bank of small, room-calibrated specialists for **presence, posture, breathing, heartbeat, restlessness, and anomaly**. Stages: guided enrollment with an adaptive quality gate (event-sourced `EnrollmentSession`, re-prompts bad anchors); feature extraction (autocorrelation periodicity in breathing/HR bands + variance/motion); six small specialists (learned threshold / nearest-prototype / band-limited periodicity / novelty); a `SpecialistBank` with baseline-drift **STALE** invalidation; and a `MixtureOfSpecialists` runtime with presence short-circuit + anomaly veto + confidence gating. Specialists are statistical heads today (runnable + hardware-validated); the frozen ADR-150 HF RF Foundation Encoder backbone is the documented upgrade path.
|
||||
- **CLI:** `enroll` / `train-room` / `room-status` / `room-watch`, plus the Stage-1 `calibrate-serve` HTTP API (CORS-enabled: `POST /start`, `GET /status`, `POST /stop`, `GET /result`, `GET /baselines`, `GET /health`) and a firewall-free `scripts/csi-udp-relay.py` for local Windows ESP32 testing without admin.
|
||||
- **Multistatic fusion (ADR-029):** `MultiNodeMixture` fuses several co-located nodes (each with its own room-calibrated bank) into one room state — presence OR'd across nodes, posture/breathing/heartbeat from the highest-confidence node, a single implausible node vetoes the room's vitals. Driven via `room-watch --node-bank N:path` (repeatable), which groups live frames by `node_id` and fuses. Same-room only; cross-room is federation (ADR-105).
|
||||
- **Validated on live ESP32-S3 (COM8, `edge_tier=0` raw CSI):** baseline capture (120 frames → 52-subcarrier baseline); the real parser → feature-extraction → mixture runtime detecting breathing (~16–31 BPM); and the multistatic ingest grouping/fusing by node-id end-to-end. Full multi-anchor enrollment accuracy requires the operator to perform the poses; true 2-node fusion + phase-based breathing + RVF/HNSW storage are noted follow-ups. 54 tests pass (35 calibration + 19 CLI).
|
||||
- **WiFi-CSI pose: efficiency frontier + per-room calibration service** (ADR-150 §3.2–3.6). Two beyond-SOTA results on the MM-Fi benchmark, plus the deployment mechanism that resolves real-world generalization:
|
||||
- **Efficiency frontier** — a **75 K-param model beats published SOTA** (74.3% vs MultiFormer 72.25% torso-PCK@20); every config from `micro` up is Pareto-dominant (smaller *and* more accurate than prior work). Shipped a deployable **int4 edge model (~20 KB, verified 74.08%, 0.135 ms single-thread CPU)** — published at [`ruvnet/wifi-densepose-mmfi-pose/edge`](https://huggingface.co/ruvnet/wifi-densepose-mmfi-pose). See [`docs/benchmarks/wifi-pose-efficiency-frontier.md`](docs/benchmarks/wifi-pose-efficiency-frontier.md).
|
||||
- **Generalization solved by few-shot calibration** — zero-shot cross-subject (~64%) and cross-environment (~10%) are *not* closeable by algorithms (CORAL, DANN, instance-norm, contrastive foundation-pretraining all tested, all failed) or by more training subjects (saturates ~64%). But **~100–200 labeled in-room samples recover SOTA-level pose**: cross-subject 64→76%, **cross-environment 10→73% (60% from just 5 samples)** — deployable as a **~11 KB per-room LoRA adapter** on a frozen shared base. Full empirical chain in ADR-150 §3.2–3.6.
|
||||
- **Calibration service (complete, both model paths, cross-language verified)** — `aether-arena/calibration/`: `calibrate.py` (transformer model, `.npz` adapter) + `infer.py` (verified 3.09%→74.29% on an unseen MM-Fi room), **and `cog_calibrate.py`** which fits a `fc1.a/fc1.b/fc2.a/fc2.b` **safetensors** adapter for the deployed cog conv+MLP model (`pose_v1.safetensors`). Consumed by the Rust product engine: `InferenceEngine::with_adapter()` + `cog-pose-estimation run --config <cfg> --adapter <room.safetensors>`. Self-contained regression tests for both Python producers (`test_calibration.py`, `test_cog_calibration.py`) **plus a cross-language Rust integration test** that loads a real `cog_calibrate.py`-generated adapter fixture and asserts it activates + changes engine output. All green.
|
||||
- **Windows workspace build + test now green** (cross-platform fixes). `wifi-densepose-worldmodel` imported `tokio::net::UnixStream` unconditionally, so `cargo build/test --workspace` failed to compile on Windows (E0432) — now the OccWorld Unix-socket bridge is `#[cfg(unix)]`-gated with a clear non-unix fallback. And `wifi-densepose-bfld`'s `readme_quickstart_uses_canonical_public_api` test checked a multi-line `pipeline\n .process` needle that never matched on a CRLF checkout — now normalizes line endings. Result: **2,682 workspace tests pass / 0 fail on Windows** (the pre-merge gate was previously unrunnable there).
|
||||
- **`ruview-swarm` crate (ADR-148)** — drone swarm control system with hierarchical-mesh topology, Raft consensus, MAPPO multi-agent reinforcement learning, and CSI sensing integration. 14 modules: topology (Raft/Gossip/Mesh), formation control (virtual-structure/leader-follower/Reynolds flocking), RRT-APF path planning, auction+FNN task allocation, MARL actor + PPO training loop, security (MAVLink v2 HMAC-SHA256 signing, UWB anti-spoofing, geofencing, Remote ID, FHSS anti-jamming), 10-state fail-safe machine, and SwarmOrchestrator. ITAR-gated coordination features (USML Category VIII(h)(12)) behind `itar-unrestricted` feature.
|
||||
- **Ruflo integration for `ruview-swarm`** — feature-gated (`ruflo`) AI-agent capability layer connecting to the claude-flow daemon: AgentDB mission memory (`memory_store`/`memory_search`), HNSW pattern learning (`agentdb_pattern-store`/`-search`), AIDefence MAVLink message scanning, and SONA intelligence trajectory hooks. `RufloBackend` trait with `HttpRufloBackend` (JSON-RPC 2.0) and `MockRufloBackend` implementations.

### Security
|
||||
- **ESP32 OTA upload now fails closed when no PSK is provisioned** (#596 audit finding — critical, **breaking change for unprovisioned nodes**). `ota_check_auth()` previously returned `true` when `s_ota_psk[0] == '\0'`, so a freshly-flashed node would accept attacker-controlled firmware over plain HTTP on port 8032 from any host on the WiFi. No Secure Boot V2, no signed-image verification — a single LAN call could brick or backdoor a node. The fix rejects every OTA upload until a PSK is written to NVS (the OTA HTTP server still starts so operators can run `provision.py --ota-psk <hex>` over USB-CDC without reflashing). **Operators affected**: any deployment that relied on the unauthenticated OTA endpoint working out of the box now needs to provision a PSK before subsequent OTA pushes will succeed. Boot-time `ESP_LOGW` makes the new posture visible.
|
||||
- **Bearer-token auth accepts the scheme case-insensitively (RFC 6750) — PR #929.** `require_bearer` parsed the `Authorization` header with a case-sensitive `strip_prefix("Bearer ")`, so a *correct* `RUVIEW_API_TOKEN` sent as `Authorization: bearer <token>` (or `BEARER`, or with extra whitespace) was rejected with a confusing 401 — needless friction when enabling auth. The scheme is now matched with `eq_ignore_ascii_case` (per RFC 6750 §2.1 / RFC 7235 §2.1); the token compare is unchanged — still exact and constant-time (`ct_eq`) — so a wrong token or a non-Bearer scheme (`Basic …`) still returns 401. Audited the surrounding code while here: `ct_eq` correctly rejects length mismatch (no prefix-auth bypass) and the middleware fails closed. New `accepts_case_insensitive_bearer_scheme` test.
|
||||
- **Path-traversal vulnerabilities patched in five sensing-server endpoints** (closes #615 — critical). New `wifi_densepose_sensing_server::path_safety::safe_id()` enforces `[A-Za-z0-9._-]` only (no leading `.`, max 64 chars) before any user-controlled identifier reaches a `format!()` building a filesystem path.

# AetherArena ("AA") — The Official Spatial-Intelligence Benchmark
|
||||
|
||||
> **Public leaderboard. Private evaluation split. Open scorer. Signed results.**
|
||||
|
||||
AetherArena is a **standalone, project-agnostic benchmark** for camera-free **spatial intelligence** — pose, presence, occupancy, tracking, and vitals from RF/WiFi (and, over time, mmWave / UWB / radar / lidar / multimodal). It is **not** a single-vendor leaderboard: any team, framework, or sensing modality can enter, and every entrant — including the RuView baseline that donated the seed scorer — is scored by the identical, open, pinned harness.
|
||||
|
||||
Specified in [ADR-149](../docs/adr/ADR-149-public-community-leaderboard-huggingface.md) (Accepted).
|
||||
|
||||
Canonical home: **`ruvnet/aether-arena`** + a Hugging Face Space (deploy pending — see `STATUS`).
|
||||
|
||||
---
|
||||
|
||||
## Why
|
||||
|
||||
WiFi/RF spatial sensing has no shared yardstick — papers self-report against inconsistent splits and metrics, with **no accounting for latency, reproducibility, or privacy leakage**. AA fixes the *measurement*, not just the models: a single deterministic scorer, a private held-out split nobody can train on, and a signed result ledger that can't be silently edited.
|
||||
|
||||
## What gets measured (v0)
|
||||
|
||||
| Category | Metric | Status |
|
||||
|----------|--------|--------|
|
||||
| **Pose** | PCK@0.2 (all / torso), OKS | Ranked |
|
||||
| **Presence** | accuracy, FP/FN | Ranked |
|
||||
| **Edge latency** | p50 / p95 / p99 ms | Ranked |
|
||||
| **Determinism** | proof-hash pass/fail | Ranked (gate) |
|
||||
| Tracking (MOTA) | — | activates when multi-person clips land |
|
||||
| Vitals (BPM err) | — | activates when paired vitals ground truth lands |
|
||||
| **Privacy leakage** | membership-inference ∈ [0,1] | **gated — not ranked** until the attacker ships |
|
||||
| Cross-room | degradation ratio | coming soon |
|
||||
|
||||
The headline rank is the **category metric**; an optional `arena_score = quality × latency_factor × privacy_factor × determinism_gate` is exposed alongside (never instead) so accuracy can't win at any cost. See ADR-149 §2.5.
|
||||
|
||||
## How scoring works
|
||||
|
||||
The scorer is RuView's **already-published** `wifi-densepose-train` acceptance harness (`ruview_metrics` + ADR-145 `ablation`), run in a pinned sandbox. **You submit a model, not predictions** — predictions on data you hold prove nothing. Your model is scored against a **private** MM-Fi held-out split (CC BY-NC 4.0; Wi-Pose excluded for redistribution reasons), and one **signed, append-only** row is written to the results ledger with a determinism proof hash.
|
||||
|
||||
Submission lifecycle: `submitted → validated → quarantined → smoke_scored → full_scored → published` (or `rejected` with a reason). The model only ever runs inside a no-network, read-only-FS sandbox.
|
||||
|
||||
## Submit (when the Space is live)
|
||||
|
||||
1. Write a manifest: [`schema/aa-submission.toml`](schema/aa-submission.toml).
|
||||
2. Push your model artifact (`.safetensors` / `.rvf` / LoRA adapter) + manifest to the Space.
|
||||
3. Watch it move through the lifecycle; your signed row appears on the board.
|
||||
|
||||
## Verify it's fair (you don't have to trust us)
|
||||
|
||||
See [`VERIFY.md`](VERIFY.md) — run the **open scorer** locally on the **public smoke split**, reproduce the determinism hash, and confirm RuView's own entries were scored by the identical path. That five-step check is the launch gate (ADR-149 §7).
|
||||
|
||||
## Neutrality
|
||||
|
||||
AA is a neutral commons. The scorer is open and versioned; any metric change is a public `harness_version` bump that **re-scores all entries**. RuView donated the seed harness and enters as one baseline — it gets no special treatment (ADR-149 §2.8).

## Benchmark-first posture (per user direction)
|
||||
- **No placeholder numbers on the board.** The ledger seeds to genesis only; every result is a real scoring-pipeline witness. RuView gets no seeded baseline.
|
||||
- **Witness chain** = `inputs_sha256` (binds witness to exact inputs) + `proof_sha256` (cross-platform-stable score hash) + the append-only hash-chained ledger. Repeatability analysis (`--repeat N`) proves the proof hash is identical across runs.
|
||||
|
||||
## Blockers / decisions needed
|
||||
- **HF deploy (M6)** — token is in GCP Secret Manager (`HUGGINGFACE_API_KEY`); creating the public `ruvnet/aether-arena` Space still wants explicit go.
|
||||
- **MM-Fi is CC BY-NC** → AA must stay non-commercial / legally distinct from the commercial RuView product.
|

- **Private MM-Fi split (M5)** — needs the dataset pulled + a held-out split assembled before real public scoring replaces the smoke fixture.

# Verifying AetherArena (you don't have to trust us)
|
||||
|
||||
AA's credibility rests on a stranger being able to reproduce a score and see that the rules are fair. This is the **launch gate** (ADR-149 §7): v0 does not ship until all five checks below pass for someone with no insider access.

|
||||
|
||||
## The open scorer
|
||||
|
||||
The scoring engine is a pure-Rust, GPU-free binary: `aa_score_runner` in `wifi-densepose-train`. It runs the real `ruview_metrics` pose-acceptance harness on a fixed fixture and emits a cross-platform-stable SHA-256 **determinism proof**.
|
||||
|
||||
### Reproduce the determinism hash locally
|
||||
|
||||
```bash
|
||||
cd v2
|
||||
# Verify the committed expected hash still matches (this is the CI gate):
|
||||
cargo run -q -p wifi-densepose-train --bin aa_score_runner --no-default-features
|
||||
# → prints the witness (inputs_sha256 + proof_sha256) and "VERDICT: PASS"
|
||||
|
||||
# See the witness row as JSON:
|
||||
cargo run -q -p wifi-densepose-train --bin aa_score_runner --no-default-features -- --json
|
||||
```
|
||||
|
||||
### Witness chain — proof + repeatability analysis
|
||||
|
||||
Every score is a **witness**: `inputs_sha256` (binds it to the exact inputs scored)
|
||||
+ `proof_sha256` (cross-platform-stable hash of the quantised score) + `harness_version`.
|
||||
Witnesses are recorded in an **append-only, hash-chained ledger** (each row references
|
||||
the previous row's hash), so a silent edit to any past row breaks the chain.
|
||||
|
||||
```bash
|
||||
# Repeatability: run the scorer K times, confirm ONE identical proof hash:
|
||||
cd v2
|
||||
cargo run -q -p wifi-densepose-train --bin aa_score_runner --no-default-features -- --repeat 16
|
||||
# → {"repeatability":{"runs":16,"unique_proof_hashes":1,"repeatable":true,...}}
|
||||
|
||||
# Real model scoring (score predictions against an eval split):
|
||||
cargo run -q -p wifi-densepose-train --bin aa_score_runner --no-default-features -- \
|
||||
--split ../aether-arena/fixtures/smoke_split.json \
|
||||
--pred ../aether-arena/fixtures/smoke_pred.json --json
|
||||
|
||||
# Verify the witness ledger chain is intact (tamper-evident):
|
||||
cd ../aether-arena/ledger && python3 ledger_tools.py verify
|
||||
# → "OK: N rows, chain intact" (edit any row and it reports the broken link)
|
||||
```
|
||||
|
||||
The expected hash is committed at [`fixtures/expected_score.sha256`](fixtures/expected_score.sha256). Same harness version + same fixture → same hash on glibc / MSVC / Apple. If your local run prints `VERDICT: PASS`, you have reproduced the scorer.
|
||||
|
||||
### What happens if the scoring maths changes
|
||||
|
||||
Any edit to `ruview_metrics.rs`, `ablation.rs`, or `aa_score_runner.rs` moves the hash and **fails the CI gate** (`.github/workflows/aether-arena-harness.yml`) until the maintainer regenerates and reviews:
|
||||
|
||||
```bash
|
||||
cargo run -p wifi-densepose-train --bin aa_score_runner --no-default-features -- --generate-hash \
|
||||
> aether-arena/fixtures/expected_score.sha256
|
||||
```
|
||||
|
||||
So a scorer change is always a reviewed, public diff — never silent. That's `harness_version` pinning + `determinism_gate` in action (ADR-149 §2.4–§2.5).
|
||||
|
||||
## The five-step acceptance test (v0 launch gate)
|
||||
|
||||
A stranger must be able to:
|
||||
|
||||
1. **Submit** a model (artifact + `schema/aa-submission.toml`) with no insider help.
|
||||
2. **Get a deterministic score** — same model + same `harness_version` → same numbers.
|
||||
3. **See the signed row** appended to the public results ledger.

# RuView Calibration Service (reference implementation)
|
||||
|
||||
Turn a **shared WiFi-CSI pose base model** into a room-specific one with a **30-second labeled
|
||||
calibration** and a **~11 KB per-room LoRA adapter**. This is the deployable resolution of the
|
||||
cross-subject / cross-environment generalization problem (full study: [ADR-150 §3.3–3.6](../../docs/adr/ADR-150-rf-foundation-encoder.md)).
|
||||
|
||||
## Why
|
||||
|
||||
Zero-shot WiFi pose generalizes poorly to a **new room or new person** — an unseen room can drop a
|
||||
strong model to near-random. But that gap is **not** algorithmically closeable (CORAL, DANN,
|
||||
instance-norm, contrastive foundation-pretraining all failed) and **not** closeable by collecting
|
||||
more subjects (saturates ~64%). It **is** closeable, cheaply, at deployment time: a handful of
|
||||
labeled frames from the actual room pin down its multipath instantly.
|
||||
|
||||
| Deployment case | Zero-shot | + in-room calibration |
|
||||
|-----------------|----------:|----------------------:|
|
||||
| Same room, new person (cross-subject) | 64% | **76%** (200 samples) |
|
||||
| **New room + new person (cross-environment)** | **~10%** | **60% @ 5 samples → 73% @ 200** |
|
||||
|
||||
**Verified demo (this code, source-only base on an unseen MM-Fi room E04):**
|
||||
`zero-shot 3.09% → after 200-sample calibration 74.29%` (+71 pts).
|
||||
|
||||
## How it works
|
||||
|
||||
A frozen shared **base** (transformer + temporal attention pool + skeleton-graph head, the published
|
||||
[`ruvnet/wifi-densepose-mmfi-pose`](https://huggingface.co/ruvnet/wifi-densepose-mmfi-pose)) plus a
|
||||
tiny **LoRA adapter** (rank 8 on the input projection + pose head — **11,200 params ≈ 11 KB int8 /
|
||||
22 KB fp16**) fitted per room. Thousands of room-adapters hang off one base.
|
||||
|
||||
## Usage
|
||||
|
||||
```bash
|
||||
# 1) Capture a short labeled clip in the deployment room -> calib.npz {X:[N,3,114,10], Y:[N,17,2]}
|
||||
# (~100–200 samples recommended; below ~20 the adapter can underperform zero-shot)
|
||||
|
||||
# 2) Fit the per-room adapter (~11 KB):
|
||||
python calibrate.py --base pose_mmfi_best.pt --data calib.npz --out room.adapter.npz
|
||||
|
||||
# 3) Run calibrated inference (base + room adapter):
|
||||
python infer.py --base pose_mmfi_best.pt --adapter room.adapter.npz --data frames.npz --out kp.npy
|
||||
# omit --adapter to run the uncalibrated (zero-shot) base
|
||||
```
|
||||
|
||||
`X` is CSI amplitude `[N, 3 antennas, 114 subcarriers, 10 frames]` (per-sample standardization is
|
||||
applied internally). `Y` is `[N,17,2]` COCO keypoints in `[0,1]`.
|
||||
|
||||
## Calibration budget (measured, rank-8 LoRA, 3 seeds — ADR-150 §3.5)
|
||||
|
||||
| Labeled samples/room | cross-subject | cross-environment |
|
||||
|---------------------:|--------------:|------------------:|
|
||||
| 0 (zero-shot) | 64% | ~10% |
|
||||
| 5 | — | 60% |
|
||||
| 20 | 66% | 66% |
|
||||
| 50 | 70% | 70% |
|
||||
| 200 | 72% | 73% |
|
||||
|
||||
Knee at ~50 samples (~70%); **below ~20 samples the adapter can hurt** (too few to fit reliably).
|
||||
|
||||
## Two models, two producers (not interchangeable)
|
||||
|
||||
Adapters are **model-specific**. There are two calibration producers here:
|
||||
|
||||
| Producer | Target model | Input | Adapter format | Consumer |
|
||||
|----------|--------------|-------|----------------|----------|
|
||||
| `calibrate.py` | MM-Fi **transformer** (`pose_mmfi_best.pt`, 3×114×10) | `[N,3,114,10]` | `.npz` (`proj`/`head` LoRA) | this Python `infer.py` |
|
||||
| `cog_calibrate.py` | cog **conv+MLP** (`pose_v1.safetensors`, 56×20) | `[N,56,20]` | `.safetensors` (`fc1.a`/`fc1.b`/`fc2.a`/`fc2.b`) | Rust `cog-pose-estimation run --adapter` |
|
||||
|
||||
```bash
|
||||
# Produce a cog-format per-room adapter for the deployed Rust pose engine:
|
||||
python cog_calibrate.py --base pose_v1.safetensors --data calib.npz --out room.safetensors
|
||||
# then in the cog runtime:
|
||||
cog-pose-estimation run --config <cfg> --adapter room.safetensors
|
||||
```
|
||||
|
||||
Same LoRA *mechanism* (ADR-150 §3.5), different architecture and key layout — an adapter from one
|
||||
producer will not load into the other model.
|
||||
|
||||
## Notes
|
||||
|
||||
- **Calibration only helps when the base hasn't already seen the room.** The published flagship was
|
||||
trained on MM-Fi `random_split`, so calibrating it on an MM-Fi subject is a near-no-op (it already
|
||||
saw them); for a genuinely new real-world room it is zero-shot and calibration applies. To
|
||||
*reproduce the demo* on a held-out MM-Fi room, train a source-only base (exclude the target
|
||||
environment) — see `ADR-150 §3.6` and the few-shot harness in `aether-arena/staging/`.
|
||||
- Adapter is saved fp16 (~22 KB); quantize to int8 for the ~11 KB on-device form.
|
||||
- Inference is real-time on CPU (the 75 K-param `micro` variant runs in 0.135 ms single-thread x86;
|
||||
see [`docs/benchmarks/wifi-pose-efficiency-frontier.md`](../../docs/benchmarks/wifi-pose-efficiency-frontier.md)).

The field's standard yardstick for camera-free **spatial intelligence** (pose, presence,
|

occupancy, tracking, vitals) from RF/WiFi and, over time, mmWave / UWB / multimodal.
|

|

- **Project-agnostic** — any team, framework, or modality enters; RuView donated the seed
|
||||
scorer and is scored like everyone else.
|

- **Benchmark-first** — the board starts empty; every row is a real scoring-pipeline
|
||||
**witness** (`inputs_sha256` + `proof_sha256` + `harness_version`) in an append-only,
|
||||
hash-chained, tamper-evident ledger.
|
||||
- **Reproducible** — the scorer is open; reproduce any proof hash + repeatability locally.

**AetherArena** is the official, project-agnostic **Spatial-Intelligence Benchmark** —
|
||||
camera-free pose, presence, occupancy, tracking, and vitals from RF/WiFi (and, over
|
||||
time, mmWave / UWB / radar / multimodal). It is **not** a single-vendor board: any
|
||||
team, framework, or modality enters, and every entrant — including the RuView baseline
|
||||
that donated the seed scorer — is scored by the identical, open, pinned harness.
|
||||
|
||||
The scorer reuses RuView's released `wifi-densepose-train` acceptance harness
|
||||
(`ruview_metrics` + ablation). You submit a **model, not predictions**; it is scored
|
||||
against a **private** MM-Fi held-out split; one **witness** row (inputs hash + proof
|
||||
hash + harness version) is appended to a **hash-chained, tamper-evident ledger**.
|
||||
|
||||
**For industry:** a vendor-neutral, auditable way to compare RF-sensing models on equal
|
||||
footing — the same standardized splits, the same metric definition, the same signed,
|
||||
reproducible ledger. No more "trust our number on our split." Vendors, labs, and startups
|
||||
all submit through one pipeline and are scored identically.
|
||||
|
||||
**Generalization Track (roadmap):** the headline isn't a single in-domain number — it's a
|
||||
battery of honest tracks: MM-Fi `random_split` (in-domain), `cross_subject` (unseen people),
|
||||
cross-room, cross-device, and confidence-calibration (ECE). Cross-subject is the real
|
||||
deployment frontier and is treated as the flagship hard benchmark.
|
||||
|
||||
Spec: ADR-149. v0 ranks **pose, presence, edge-latency, determinism**. Tracking &
|
||||
vitals activate when their ground truth lands; **privacy-leakage** is gated until the
|
||||
membership-inference attacker ships. Source + the open scorer:

|

1. Write a manifest — [`schema/aa-submission.toml`](https://github.com/ruvnet/RuView/blob/main/aether-arena/schema/aa-submission.toml):
|
||||
declare your model ref, category, the ADR-145 feature set (F0 CSI … F3 BFLD), and the tensor I/O contract.
|
||||
2. Provide your model artifact (`.safetensors` / `.rvf` / LoRA adapter).
|
||||
3. It moves through `submitted → validated → quarantined → smoke_scored → full_scored → published`,
|
||||
scored in a no-network, read-only sandbox against the private split.

4. Your signed witness row appears on the leaderboard.

```bash

# repeatability — N runs, one identical proof hash:

cargo run -q -p wifi-densepose-train --bin aa_score_runner --no-default-features -- --repeat 16

# ADR-149: AetherArena ("AA") — The Official Spatial-Intelligence Benchmark (Hugging Face)

> **Scope note:** AetherArena is a **standalone, project-agnostic benchmark** for spatial intelligence — open to *any* project, team, or modality, not a RuView-branded board. RuView contributes the initial scoring harness and enters as one baseline among others; it gets no special treatment. This ADR lives in the RuView repo only because RuView is donating the seed harness — the benchmark itself is independent.

|

---
|
||||
|
||||
## 1. Context
|
||||
|
||||
### 1.1 The Gap
|
||||
|
||||
RuView has a mature, deterministic evaluation surface but **no public face for it**. Two assets already exist:
|
||||
|
||||
1. **A grading harness.** `wifi-densepose-train/src/ruview_metrics.rs` rolls pose (PCK@0.2 / OKS / torso jitter / p95 error), tracking (MOTA / ID-switches / fragmentation), and vitals (breathing/heartbeat BPM error + SNR) into a `RuViewAcceptanceResult` with a `RuViewTier` (`Fail` / `Bronze` / `Silver` / `Gold`). ADR-145's `src/ablation.rs` extends this with presence accuracy, localization error, FP/FN, latency p50/p95/p99, a privacy-leakage score ∈ `[0,1]`, and cross-room degradation, under a determinism binding inherited from the ADR-011 proof harness.
|
||||
|
||||
2. **A determinism substrate.** `proof.rs` (`PROOF_SEED=42`) SHA-256-hashes model outputs against an expected hash, so a scored run is reproducible and tamper-evident.
|
||||
|
||||
What is missing is a **public, multi-entrant ranking**. As surveyed in ADR-015 and `docs/research/sota-surveys/sota-wifi-sensing-2025.md`, the WiFi-sensing field has **no hosted live leaderboard** the way vision has COCO/EvalAI — researchers self-report numbers against public *datasets* (MM-Fi, Wi-Pose, Person-in-WiFi, Widar3.0) in papers, with inconsistent splits, metrics, and no privacy or latency accounting. RuView's own pose number (PCK@20 ≈ 2.5% with proxy labels, target 35%+ per ADR-079) is currently self-reported on a private validation set and is not comparable to the MM-Fi SOTA (MultiFormer 0.7225).
|
||||
|
||||
### 1.2 The Opportunity
|
||||
|
||||
The harness that already gates RuView releases is exactly the engine a community leaderboard needs: a single, deterministic, privacy- and latency-aware scoring function. Publishing it as an open leaderboard:
|
||||
|
||||
- Establishes **AetherArena as the field's standard yardstick** for spatial intelligence, with RuView's `RuViewTier` + ADR-145 metric set contributed as its initial basis (pose + tracking + vitals + **privacy-leakage** + latency + determinism — a combination no existing benchmark scores). The standard is AA's; RuView donates the seed.
|
||||
- Draws **any project, framework, or modality** to submit and rank — a cross-project community flywheel, not a RuView-only one (RuView's `wifi-densepose-pretrained` is merely the first baseline).
|
||||
- Forces the harness to harden: a public, neutral scorer must be reproducible by strangers, resistant to gaming, and runnable on a fixed held-out split nobody can train on.
|
||||
|
||||
### 1.3 Constraints & Risks Up Front
|
||||
|
||||
- **Leakage of the held-out split** is the existential risk for any leaderboard. The eval data must be private; submitters provide a model, not predictions on data they hold.
|
||||
- **Compute cost.** Scoring a submission runs inference over the eval set; an HF Space on free CPU may be too slow for the Candle/`tch` pipeline. Tiering of compute (CPU smoke vs GPU full score) is required.
|
||||
- **Privacy / consent of the eval data.** MM-Fi and Wi-Pose carry their own licenses; we can host *derived* CSI features and scores but must respect redistribution terms (ADR-015 already tracks this).
|
||||
- **Trust.** A `RuViewTier` badge is only meaningful if the scoring is deterministic and the leaderboard cannot be silently edited — the ADR-011 proof hash and a signed results ledger address this.
|
||||
|
||||
---
|
||||
|
||||
## 2. Decision
|
||||
|
||||
**Create AetherArena ("AA") — the official, project-agnostic Spatial-Intelligence Benchmark: a public, open-entry leaderboard for camera-free spatial perception (pose, presence, occupancy, tracking, vitals) as a standalone repo `ruvnet/aether-arena` paired with a Hugging Face Space. The scoring engine is seeded by RuView's existing `ruview_metrics` + ADR-145 ablation harness, contributed as a neutral scorer; v0 evaluates against a private MM-Fi held-out split.**
|
||||
|
||||
AA is **not a RuView leaderboard**. It is the field's missing standard yardstick for spatial intelligence — open to any team, framework, or sensing modality. The RF medium is the v0 input and RuView donates the seed harness + a baseline entry, but the benchmark is independent and RuView is scored like every other entrant. The metric surface — pose, presence, tracking, occupancy/world-model, latency, determinism, and later privacy — is modality-agnostic, leaving room to grow to mmWave / UWB / radar / lidar / multimodal entrants and other projects.
|
||||
|
||||
The leaderboard does **not** fork or re-implement the scoring logic. It is a thin orchestration + presentation layer over the published `wifi-densepose-cli` scorer, so the public number a model earns is identical to the number RuView uses internally to gate releases. **This makes the leaderboard governance, not marketing.**
|
||||
|
||||
The whole design reduces to a precise four-part structure:
|
||||
|
||||
> **Public leaderboard. Private evaluation split. Open scorer. Signed results.**
|
||||
|
||||
- **Public leaderboard** — anyone can see the ranking and submit.
|
||||
- **Private evaluation split** — the held-out data is never published; it cannot be trained on or overfit.
|
||||
- **Open scorer** — the scoring code is the published `wifi-densepose-cli`; a stranger can rerun it locally on a public *smoke* split and reproduce the logic.
|
||||
- **Signed results** — every score is an append-only, signed ledger row with a determinism proof hash; ranks cannot be silently edited.
|
||||
|
||||
### 2.1 Name — DECIDED: `ruvnet/aether-arena` ("AA")
|
||||
|
||||
**Locked.** Canonical repo + HF Space: **`ruvnet/aether-arena`**, branded **AetherArena** with the short form **"AA"**.
|
||||
|
||||
- **"Aether"** = the classical all-pervading medium — fitting for RF/ambient spatial perception, and broader than "Ether"/CSI/WiFi so the benchmark can grow to mmWave, UWB, and multimodal spatial-intelligence entrants without a rename.
|
||||
- **"Arena"** = open competitive entry.
|
||||
- HF Space title: *AetherArena (AA) — the spatial-intelligence benchmark for RF perception.*
|
||||
- `ruvnet/wifi-densepose-leaderboard` is kept only as a discoverability/topic alias that redirects to AA.
|
||||
|
||||
(Rejected: `csi-arena` — jargon; `rf-bench` — generic/collision; `wifi-densepose-leaderboard` as the primary — ties the brand to one capability.)

leaderboard.parquet ◄────────────────────┘ │ privacy-leakage, cross-room
|
||||
(HF dataset, append-only, └─ emit result + SHA-256 proof
|
||||
one signed row per submission)
|
||||
```
|
||||
|
||||
1. **Submission contract.** A submitter pushes a model artifact (`model.safetensors` / `.rvf` / LoRA adapter) plus a `ruview-arena.toml` manifest declaring: input feature set (which ADR-145 `FeatureSet` it consumes — F0 CSI / F1 CIR / F2 Doppler / F3 BFLD), tensor I/O contract, license, and optional category (pose / presence / tracking / vitals / multi-task).
|
||||
2. **Scoring.** The Space runs the **published `wifi-densepose-cli`** in a pinned container against a **private held-out split** of MM-Fi / Wi-Pose (and RuView's own paired-capture set per ADR-079). Output is the existing `RuViewAcceptanceResult` + the ADR-145 scalar set, plus the ADR-011 SHA-256 reproducibility hash.
|
||||
3. **Ledger.** Each scored submission appends **one signed row** to an append-only HF dataset (`ruvnet/aether-arena-results`, Parquet): `{submitter, model_ref, category, feature_set, tier, pck20, oks, mota, vitals_bpm_err, latency_p50, latency_p95, privacy_leakage, cross_room_deg, proof_sha256, scored_at, harness_version}`. Append-only + signed = no silent edits.
|
||||
4. **Presentation.** Gradio leaderboard with category tabs (Pose / Presence / Tracking / Vitals / Edge-latency / **Privacy**), `RuViewTier` badges, and a "privacy-respecting" filter (leakage ≤ threshold) — the differentiator no other WiFi benchmark has.
|
||||
|
||||
### 2.2.1 Submission Lifecycle (quarantine before scoring)
|
||||
|
||||
A submission is an untrusted artifact, so it moves through an explicit state machine — artifacts are isolated and validated **before** any scoring touches the private split. This is both the abuse-handling boundary and the UI flow:
|
||||
|
||||
| State | Meaning |
|
||||
|-------|---------|
|
||||
| `submitted` | manifest received, job queued |
|
||||
| `validated` | schema, license, and artifact type accepted |
|
||||
| `quarantined` | artifact scanned; loaded into the sandbox (network disabled, read-only FS, runtime prepared) |
|
||||
| `smoke_scored` | passes the **public** smoke split (cheap CPU correctness check) |
|
||||
| `full_scored` | **private** held-out split score produced |
|
||||
| `published` | signed row appended to the ledger; appears on the board |
|
||||
| `rejected` | failed a gate — terminal, with a machine-readable reason |
|
||||
|
||||
Only `quarantined` → `smoke_scored` → `full_scored` ever runs the model, always inside the sandbox of §2.4. A failure at any gate transitions to `rejected` with a reason rather than silently dropping.
|
||||
|
||||
### 2.3 Categories & Metrics (reuse, do not invent)
|
||||
|
||||
| Category | Primary metric (existing) | Source |
|
||||
|----------|---------------------------|--------|
|
||||
| Pose | PCK@20, OKS | `ruview_metrics::evaluate_joint_error` |
|
||||
| Tracking | MOTA, ID-switches | `ruview_metrics::evaluate_tracking` |
|
||||
| Vitals | breathing/HR BPM error, SNR | `ruview_metrics::evaluate_vital_signs` |
|
||||
| Presence | accuracy, FP/FN | ADR-145 `ablation.rs` |
|
||||
| Edge latency | p50 / p95 / p99 ms | ADR-145 `LatencyProfile` |
|
||||
| **Privacy** | leakage score ∈ `[0,1]` (membership-inference) | ADR-145 §10 |
|
||||
| Cross-room | degradation ratio | ADR-027 / ADR-145 |
|
||||
| Overall | `RuViewTier` Bronze/Silver/Gold + `arena_score` (§2.5) | `determine_tier()` |
|
||||
|
||||
### 2.3.1 Phased Launch — v0 ships narrow
|
||||
|
||||
**A narrow leaderboard that works beats a broad one with half-real metrics.** v0 ranks only categories whose metric is fully implemented and reproducible-by-strangers today; the rest are visible as **"coming soon" / gated** and are **not ranked** until their metric is real.
|
||||
|
||||
| Category | v0 status | Gate to activate |
|
||||
|----------|-----------|------------------|
|
||||
| Presence | **Ranked** | — (implemented) |
|
||||
| Pose (PCK@20 / OKS) | **Ranked** | — (implemented) |
|
||||
| Edge latency (p50/p95/p99) | **Ranked** | — (implemented) |
|
||||
| Determinism proof | **Ranked** (pass/fail gate) | — (ADR-011, implemented) |
|
||||
| Tracking (MOTA) | Optional in v0 | enough multi-person eval clips in the private split |
|
||||
| Vitals (BPM error) | Optional in v0 | paired vital-sign ground truth in the split |
|
||||
| **Privacy leakage** | **Coming soon — gated, not ranked** | ADR-145 §10 membership-inference attacker implemented + published |
|
||||
| Cross-room generalization | Coming soon | multi-room held-out split assembled (ADR-027) |
|
||||
|
||||
**v0 launch language (explicit, to stay honest and non-contradictory):** *AetherArena v0 starts with pose, presence, edge latency, and deterministic reproducibility. Tracking and vitals are activated when sufficient ground-truth clips are available. Privacy-leakage and cross-room generalization remain gated until their evaluation attacks and splits are implemented and published.* Shipping a "privacy leaderboard" claim before the attacker exists would be an easy and deserved attack on our credibility.
|
||||
|
||||
### 2.4 Threat Model
|
||||
|
||||
The leaderboard is only credible if its failure modes cannot be hidden. Explicit threats and the control that neutralizes each:
|
||||
|
||||
| Threat | Control |
|
||||
|--------|---------|
|
||||
| Model exfiltrates / phones home the eval data | Scorer container runs with **no network, read-only eval FS, resource caps** (sandboxed) |
|
||||
| Submitter overfits the public split | **Private held-out split** — never published; scoring runs on data the submitter has never seen |
|
||||
| Model fingerprints / detects the eval set | **Seasonal rotation** of a fraction of the held-out split (mirrors ADR-120 hash rotation) |
|
||||
| Maintainer silently edits a score / rank | **Witness chain**: append-only, hash-chained ledger (`ledger/ledger_tools.py`) — each row references the prior row's hash, so any edit breaks every subsequent link and `verify` fails |
|
||||
| A score can't be reproduced / hides nondeterminism | **Witness + repeatability analysis**: each score is a witness (`inputs_sha256` binding it to the exact inputs + `proof_sha256` of the quantised result + `harness_version`); `aa_score_runner --repeat N` runs the harness N× and fails if it ever produces ≥2 distinct proof hashes |
|
||||
| Scorer version drift changes ranks invisibly | **`harness_version` pinned per witness**; a scorer change moves the proof hash and fails the CI determinism gate until regenerated + reviewed |
|
||||
| Slow model brute-forces accuracy | **Latency is a ranked axis** (p50/p95/p99) with hard caps + the `latency_factor` in `arena_score` |
|
||||
| "Gold accuracy, leaks identity" win | **Privacy is a (gated) axis**; once active, `privacy_factor` penalizes leakage in `arena_score` |
|
||||
| Malicious model artifact (RCE in the scorer) | Untrusted artifact loaded in the sandboxed container only; pinned, minimal runtime; no host mounts |
|
||||
|
||||
### 2.5 Overall Score (anti-"accuracy-at-any-cost")
|
||||
|
||||
Categories are ranked independently (tabs), **and** an optional headline `arena_score` composes them so a model cannot win on raw accuracy while being slow, leaky, or non-reproducible:
|
||||
|
||||
```
|
||||
arena_score = quality_score × latency_factor × privacy_factor × determinism_gate
|
||||
```
|
||||
|
||||
| Component | Rule |
|
||||
|-----------|------|
|
||||
| `quality_score` | normalized blend of PCK@20 / OKS / MOTA / vitals for the category, ∈ `[0,1]` |
|
||||
| `latency_factor` | `1.0` if p95 ≤ target; decays smoothly above target (edge viability) |
|
||||
| `privacy_factor` | `1.0 − privacy_leakage` once the Privacy axis is active; **fixed at `1.0` in v0** (privacy gated/unranked) |
|
||||
| `determinism_gate` | `1.0` if the ADR-011 proof hash matches; **`0` if it fails** — a non-reproducible run cannot rank at all |
|
||||
|
||||
The multiplicative form means any single hard failure (non-deterministic, or — later — high leakage) collapses the headline score, even at SOTA accuracy. In v0, `privacy_factor` is pinned to `1.0` so the headline number is honest about what is actually measured.
|
||||
|
||||
**`arena_score` is a gate, not the only headline.** Multiplicative composites are great for gating but can hide *why* a model lost, and invite "your formula is biased" arguments. So the board ranks **category performance first** and exposes the composite alongside, never instead:
|
||||
|
||||
| Surface | What it shows |
|
||||
|---------|---------------|
|
||||
| **Primary rank** | the category metric (e.g. PCK@20 for Pose) — this is the sort key per tab |
|
||||
| **Integrity badge** | determinism proof pass/fail |
|
||||
| **Edge badge** | p95 latency band |
|
||||
| **Overall score** | `arena_score` as an *optional* governance-weighted composite |
|
||||
|
||||
> The leaderboard ranks category performance first, then exposes `arena_score` as a governance-weighted composite so accuracy, latency, reproducibility, and privacy are visible rather than collapsed into a single opaque number.
|
||||
|
||||
### 2.6 Dataset Legality (investigated — resolved for v0)
|
||||
|
||||
Confirmed against ADR-015 §dataset-licenses:
|
||||
|
||||
| Dataset | License | What AA may do |
|
||||
|---------|---------|----------------|
|
||||
| **MM-Fi** | **CC BY-NC 4.0** | ✅ v0 eval source. Non-commercial use + derivatives **permitted with attribution**. AA may host *derived* CSI features and scores; raw frames stay in the private split. AA must be operated **non-commercially** and carry MM-Fi attribution. |
|
||||
| **Wi-Pose** | **"Research use"** (no clean redistribution grant) | ⚠️ **Not hosted.** Pulled privately into the scorer only, never redistributed; or deferred until terms are clarified with the authors. **Dropped from v0.** |
|
||||
| Person-in-WiFi-3D | semi-public access | Future candidate (post-v0), pending access terms. |
|
||||
|
||||
**v0 decision:** evaluate on a **private MM-Fi held-out split only** (CC BY-NC, attributed, non-commercial; expose only license-permitted derived features). Wi-Pose is removed from v0 and revisited if/when redistribution is cleared. This keeps the existential "can we even host this" risk at zero for launch.
|
||||
|
||||
> **Non-commercial caveat to watch:** CC BY-NC means AA itself, and the eval-data use, must remain non-commercial. Because AA also showcases the (commercial) RuView appliance, keep AA legally distinct and non-commercial, or seek an MM-Fi commercial grant before any paid tier. Flagged for the maintainer.
|
||||
|
||||
### 2.7 Non-Gameability Is a Launch Gate
|
||||
|
||||
Per the explicit directive, AA does not launch unless the harness is demonstrably hard to game. The controls (private split §2.4, seasonal rotation §2.4, model-not-prediction submission §2.2, sandbox §2.4, pinned `harness_version` §2.4, signed append-only ledger §2.3-§2.4, multiplicative `arena_score` §2.5, `determinism_gate=0` on proof-hash failure §2.5) are **not optional hardening — they are acceptance criteria** (see §7). A v0 that can be topped by overfitting a public split, a non-reproducible run, or a silently edited row is, by definition, not ready.
|
||||
|
||||
### 2.8 Neutrality & Governance (because it's "official" and cross-project)
|
||||
|
||||
The hardest credibility problem for an *official* benchmark seeded by one entrant: **"RuView built the scorer, so of course RuView wins."** If AA is to be the field's standard rather than RuView marketing, neutrality must be structural, not promised:
|
||||
|
||||
| Neutrality risk | Control |
|
||||
|-----------------|---------|
|
||||
| RuView's entry gets special treatment | RuView is submitted through the **same** public pipeline (§2.2.1) and scored by the **same** pinned scorer as everyone else; its rows carry the same proof hash and are independently re-runnable on the smoke split. |
|
||||
| RuView tunes the metric to favor its models | The scorer is **open and versioned**; any metric change is a public `harness_version` bump that **re-scores all entries**, not just new ones. Metric changes go through a public changelog. |
|
||||
| "Official" is self-declared | AA is positioned as a **neutral commons**: separate repo/Space identity, contribution guide, and an explicit invitation for other projects + dataset authors to co-own splits and metrics. RuView is the *donor of the seed harness*, not the owner of the standard. |
|
||||
| Benchmark used as RuView ad | Keep AA legally + brand-distinct (ties into the CC BY-NC non-commercial caveat, §2.6); the README leads with the standard, not the product. |
|
||||
| Single-vendor capture | Roadmap to a multi-org steering/eval committee once ≥N external projects enter; split rotation + metric proposals are public. |
|
||||
|
||||
The test for neutrality is the same as §7's acceptance test: a stranger from *another project* can submit, reproduce the score, and see that RuView's own entries were scored by the identical, open, pinned path.
|
||||
|
||||
---
|
||||
|
||||
## 3. Consequences
|
||||
|
||||
### 3.1 Positive
|
||||
- A real, comparable public number for RuView (and everyone else) on MM-Fi / Wi-Pose, scored by a privacy- and latency-aware harness no other WiFi benchmark offers.
|
||||
- Community flywheel: external models/adapters get ranked, feeding `ruvnet/wifi-densepose-pretrained`.
|
||||
- Forces the harness to be reproducible-by-strangers, which strengthens internal release gating too.
|
||||
|
||||
### 3.2 Negative / Costs
|
||||
- **New repo + HF Space to maintain**, incl. a scoring container and queue. Ongoing compute cost (mitigate: CPU smoke-score on submit, batched GPU full-score on a schedule).
|
||||
- **Dataset licensing** must be cleared for hosting derived MM-Fi / Wi-Pose features (ADR-015 owns this; may require contacting dataset authors).
|
||||
- **Abuse surface** (malicious model artifacts run in the scorer) — must sandbox the container (no network, read-only eval data, resource caps).
|
||||
|
||||
### 3.3 Neutral
|
||||
- The scoring logic stays in `wifi-densepose-train`/`-cli`; the leaderboard is presentation only, so it does not bloat the core workspace.
|
||||
|
||||
---
|
||||
|
||||
## 4. Alternatives Considered
|
||||
|
||||
1. **Submit RuView to existing venues only (MM-Fi GitHub, Papers-with-Code).** Lower effort, but no privacy/latency axes, no live entry, and RuView doesn't own the standard. *Complementary, not exclusive — we should still post MM-Fi numbers.*
|
||||
2. **A static numbers page in the RuView README.** Zero infra, but not multi-entrant and not a leaderboard.
|
||||
3. **EvalAI / Kaggle competition.** Stronger anti-gaming infra, but heavyweight, time-boxed, and off-brand vs an always-open HF Space next to the model.
|
||||
|
||||
---
|
||||
|
||||
## 5. Open Questions
|
||||
|
||||
1. **Eval data hosting** — can we redistribute derived MM-Fi / Wi-Pose CSI features under their licenses, or must scoring pull the raw datasets the submitter cannot see? (Owner: ADR-015 follow-up.)
|
||||
2. **Compute budget** — free HF CPU Space, ZeroGPU, or a self-hosted scorer on the GCloud A100/L4 fleet (`cognitum-20260110`)?
|
||||
3. **Name lock** — confirm `aether-arena` vs `wifi-densepose-leaderboard`.
|
||||
4. **Season cadence** — does the held-out split rotate monthly, and do we keep an all-time + per-season board?
|
||||
5. **Privacy-leakage attack** — ship the membership-inference attacker (ADR-145 §10 is currently a *defined-but-unimplemented* metric) before launch, or launch with privacy as a "coming soon" axis?
|
||||
|
||||
---
|
||||
|
||||
## 6. Implementation Sketch (if accepted)
|
||||
|
||||
- **P1** — Stand up `ruvnet/aether-arena` repo + skeleton Gradio HF Space; define `ruview-arena.toml` submission contract; publish a **public smoke split** a stranger can score locally.
|
||||
- **P2** — Containerize `wifi-densepose-cli score` as the pinned, sandboxed scorer (no network, read-only FS, caps); wire the signed append-only Parquet ledger + `determinism_gate`.
|
||||
- **P3 — v0 LAUNCH (narrow).** Clear + load the private MM-Fi / Wi-Pose held-out split; activate **Presence, Pose, Edge-latency, Determinism** categories; seed the board with RuView's own `wifi-densepose-pretrained` baseline (honest current PCK@20). Tracking/Vitals optional. Privacy + Cross-room shown as **gated / coming soon**.
|
||||
- **P4** — *(post-launch, gated)* Implement the ADR-145 §10 privacy-leakage membership-inference attacker; only then activate + rank the **Privacy** category and switch `privacy_factor` on in `arena_score`.
|
||||
- **P5** — Assemble the multi-room split → activate **Cross-room**. Submit RuView's MM-Fi number to Papers-with-Code in parallel (alternative #1).
|
||||
|
||||
## 7. Acceptance Test (definition of done for v0)
|
||||
|
||||
v0 launches **only when a stranger can:**
|
||||
|
||||
1. **Submit** a model (artifact + `ruview-arena.toml`) through the Space with no insider help,
|
||||
2. **Get a deterministic score** back (same model + same harness version → same numbers),
|
||||
3. **See the signed row** appended to the public results ledger,
|
||||
4. **Rerun the scorer locally** on the public *smoke* split and reproduce the logic, and
|
||||
5. **Understand why the rank is fair** — private split, open scorer, pinned version, proof hash — from the docs alone.
|
||||
|
||||
If any of these five fails, v0 is not ready.
|
||||
|
||||
## 8. Suggested Announcement (draft)
|
||||
|
||||
> **I'm proposing AetherArena** — a public leaderboard for WiFi sensing, RF perception, and ambient intelligence.
|
||||
>
|
||||
> The problem with this field is not just model quality. It is *measurement* quality. Most WiFi-sensing work reports numbers against datasets with inconsistent splits, inconsistent metrics, and almost no accounting for latency, privacy leakage, reproducibility, or edge viability.
|
||||
>
|
||||
> AetherArena fixes that. Models are submitted, scored in a pinned sandboxed container against **private** held-out MM-Fi and Wi-Pose splits, and written to a **signed append-only** results ledger. The scoring engine reuses the same RuView harness we use internally: pose, presence, tracking, vitals, latency, cross-room degradation, deterministic proof hashes — and, once its attacker ships, privacy leakage.
|
||||
>
|
||||
> The goal is not to make RuView look good. The goal is to make the *category* measurable. If ambient intelligence is going to move from demos to infrastructure, it needs public numbers, reproducible commands, private eval splits, and failure modes that cannot be hidden.

# ADR-150: RuView RF Foundation Encoder — pose-preserving, subject/room/device-invariant CSI embedding
|
||||
|
||||
| Field | Value |
|
||||
|-------|-------|
|
||||
| **Status** | Proposed |
|
||||
| **Date** | 2026-05-30 |
|
||||
| **Deciders** | ruv |
|
||||
| **Codebase target** | New `wifi-densepose-rfencoder` (or `nn/src/rf_foundation.rs`) + training in `wifi-densepose-train`; consumed by the MM-Fi pose head and the AetherArena Generalization Track (ADR-149) |
|
||||
| **Relates to** | ADR-024 (Contrastive CSI Embedding / AETHER), ADR-027 (Cross-Environment Domain Generalization / MERIDIAN), ADR-134 (CIR), ADR-135 (calibration + coherence gate), ADR-145 (Ablation/Eval Harness), ADR-149 (AetherArena benchmark) |
|
||||
|
||||
---
|
||||
|
||||
## 1. Context
|
||||
|
||||
AetherArena now has a published, metric- and protocol-matched MM-Fi result: **81.63% torso-PCK@20 in-domain (random_split), exceeding MultiFormer's 72.25%** ([#876](https://github.com/ruvnet/RuView/issues/876)). But the **leakage-free cross-subject** number collapses to **~11.6% torso-PCK** (27% under the looser bbox metric). That gap is the real deployment frontier — homes, elder care, festivals, unseen bodies.
|
||||
|
||||
Naïve fixes already tested and **failed**: a subject-adversarial (DANN) embedding did not move cross-subject (baseline 27.26% → DANN 27.54% bbox; torso 11.57%). Bigger capacity *hurt* (transformer cross-subject 24.8% < conv 27.3%) — extra parameters overfit seen subjects.
|
||||
|
||||
**Conclusion:** a *generic* "better feature vector" will not help. The lever is an embedding trained for the **right invariance** — one that preserves pose while removing subject, room, and device signatures, and that *exposes* channel instability rather than hiding it.
|
||||
|
||||
### 1.1 Why DANN failed (and the corrected rule)
|
||||
|
||||
Subject identity is partly **entangled with valid pose evidence** — body scale, limb proportions, gait, RF scattering. Blindly erasing subject info also erases information the pose decoder needs. The corrected rule:
|
||||
|
||||
> **Remove subject identity only after preserving pose geometry.** Supervised *pose-contrast across subjects* beats naïve adversarial identity removal.
|
||||
|
||||
The frontier objective is **not** `same-subject = positive`. It is:
|
||||
|
||||
> **same pose across different subjects = positive; different pose = negative.**
|
||||
|
||||
## 2. Decision
|
||||
|
||||
**Build the RuView RF Foundation Encoder: a self-supervised, pose-preserving, subject/room/device-invariant RF representation for CSI (extensible to CIR, ADR-134, and BFLD).** Positioned as a **platform primitive**, not a benchmark trick.
|
||||
|
||||
### 2.1 What the embedding must keep / remove
|
||||
|
||||
| Signal | Action | Why |
|
||||
|--------|--------|-----|
|
||||
| Pose geometry | **Keep** | target signal |
|
||||
| Limb-motion deltas | **Keep** | strong temporal cue |
|
||||
| Subject identity | **Remove** (post-pose) | causes overfit |
|
||||
| Static room multipath | **Remove** | breaks transfer |
|
||||
| Device-specific phase artifacts | **Remove** | breaks cross-hardware |
|
||||
| Antenna-layout quirks | **Normalize** | deployment portability |
|
||||
| Channel instability | **Expose separately** | confidence gating / anti-hallucination |
|
||||
|
||||
### 2.2 Architecture
|
||||
|
||||
```
|
||||
CSI frame sequence
|
||||
→ physics normalization (antenna geometry, subcarrier stability, phase-unwrap quality, room-impulse structure)
|
||||
→ masked CSI encoder (SSL: learn channel structure from unlabeled CSI — 150k home + 320k MM-Fi frames)
|
||||
→ temporal contrastive encoder (motion continuity)
|
||||
→ skeleton-aware pose decoder (graph head — anatomical constraints, GraphPose-Fi style, arXiv 2511.19105)
|
||||
→ confidence + coherence head (mincut / spectral coherence as RF-integrity signal)
|
||||
```
|
||||
|
||||
### 2.3 Training objectives (loss stack)
|
||||
|
||||
```
|
||||
L_total = L_pose
|
||||
+ 0.20 · L_masked_csi # learn channel structure (unlabeled)
|
||||
+ 0.10 · L_temporal_contrast # motion continuity
|
||||
+ 0.20 · L_pose_contrast # same-pose-across-subjects = positive ← the frontier
|
||||
+ 0.05 · L_subject_decorrelation # remove identity only where it conflicts with pose
|
||||
+ 0.10 · L_coherence # predict when RF evidence is weak
|
||||
```
|
||||
|
||||
Invariant target:
|
||||
```
|
||||
embedding ≈ pose + motion + channel-coherence
|
||||
embedding ≠ subject-identity + static-room-signature + device-artifact
|
||||
```
|
||||
|
||||
### 2.4 The RuView differentiator — auditable RF perception that knows when it's wrong
|
||||
|
||||
The coherence head gates pose confidence by **channel coherence**: when multipath structure changes (mincut / spectral coherence drop), the model flags low RF integrity instead of hallucinating a pose. This is the **anti-hallucination** component most WiFi-pose papers lack, and it turns RuView from a model into sensing infrastructure. (Ties to ADR-135 coherence gate.)
|
||||
|
||||
## 3. Experiment plan — three variants, frozen-decoder test
|
||||
|
||||
Same split, same decoder, same seed set; only the embedding changes.
|
||||
|

|
||||

|

|

### 3.1 Expected gains (estimate)
|
||||
|
||||
| Method | cross-subject torso-PCK gain |
|
||||
|--------|------------------------------|
|
||||
| Naïve embedding | 0–2 |
|
||||
| DANN adversarial | 0–3 (high collapse risk) — *empirically ~0* |
|
||||
| Masked CSI pretrain | +3–8 |
|
||||
| Pose-contrastive | +5–12 |
|
||||
| Physics-norm + SSL + graph decoder | +10–20 |
|
||||
| + more subject-diverse paired data | +20 |
|
||||
|
||||
Plausible trajectory: 11.6% → **20–25% near term**, **30–40% with enough subject/environment diversity**. That is a stronger research claim than squeezing random-split from 81.6% → 88%.
|
||||
|
||||
### 3.2 Empirical findings (2026-05-31) — measured, not estimated
|
||||
|
||||
The near-term algorithmic estimates in §3.1 were **tested directly on the official MM-Fi
|
||||
cross-subject split** (256,608 train / 64,152 test, same TF pipeline). Measured results:
|
||||
|
||||
| Method | §3.1 estimate | **Measured** | Verdict |
|
||||
|--------|--------------:|-------------:|---------|
|
||||
| Baseline (in-harness) | — | 63.13% (doc TTA 64.04) | reference |
|
||||
| Mixup | n/a | **+0.7** → 63.79% | ✅ small |
|
||||
| Mixup + TTA + 3-seed ensemble | n/a | **+0.9** → **64.92%** | ✅ **best** |
|
||||
| Per-antenna instance-norm + SpecAugment | n/a | **−4.6** → 58.52% | ❌ destroys cross-antenna pose structure |
|
||||
| **Pose-contrastive foundation pretrain** | **+5 to +12** | **−2.3** → 62.65% | ❌ **refuted** |
|
||||
| DANN adversarial | ~0 | ~0 | ❌ (as predicted) |
|
||||
|
||||
**Why pose-contrastive pretraining fails — the key finding.** The supervised-contrastive
|
||||
pretraining loss (positives = same pose-cluster, spanning subjects) **never left the
|
||||
uniform-similarity floor `ln(B)`** — across cluster granularities K∈{48,256}, batch sizes
|
||||
{768,1024}, and 3 seeds. The same encoder trivially aligns *temporally-adjacent* frames
|
||||
(temporal-triplet SSL reached 82%), so the optimizer works; it simply **cannot pull same-pose
|
||||
CSI from different subjects together — that invariance is not present in the data to be learned.**
|
||||
|
||||
**Implication for this ADR.** The 18-pt in-domain↔cross-subject gap (83.6% → best 64.9%) is
|
||||
**fundamental subject-distribution shift in CSI, not an algorithmic gap.** No invariance-learning
|
||||
method tested moves it; only variance-reduction (mixup + ensemble) gives <1 pt. This **promotes
|
||||
"more subject-diverse paired data" (§3.1 last row, §6 alt 3) from complementary to the *primary*
|
||||
lever** and **demotes pure-SSL-on-existing-data** as a near-term cross-subject win. The encoder is
|
||||
still worth building for masked-CSI representation reuse and the coherence integrity head, but the
|
||||
cross-subject acceptance gate (§4, ≥6 pts) is **unlikely to be met without new multi-subject
|
||||
capture** (fleet: `cognitum-seed-1` + multi-room, see `CLAUDE.local.md`). Recommend re-scoping
|
||||
phase 1 around data collection before further loss-stack engineering.
|
||||
|
||||
### 3.3 Subject-scaling study (2026-05-31) — capture *diversity*, not *volume*
|
||||
|
||||
Before committing to capture, we measured **how cross-subject accuracy scales with the number of
|
||||
training subjects** (fixed held-out test subjects, official split, mixup+TTA):
|
||||
|
||||
| N subjects | 4 | 8 | 12 | 16 | 20 | 24 | 32 |
|
||||
|-----------:|--:|--:|---:|---:|---:|---:|---:|
|
||||
| xsubj-PCK@20 | 36.7 | 57.7 | 58.3 | 61.1 | 62.7 | 63.3 | **63.7** |
|
||||
|
||||
The curve **saturates**: 4→8 subjects = **+21 pts**, but 24→32 = **+0.45 pts**. Asymptote ≈ 64–65%,
|
||||
still ~19 pts under in-domain. **Key correction to the "more data" recommendation:** simply capturing
|
||||
*more people from the same distribution* will **not** close the gap — subject-count returns vanish
|
||||
past ~16–20 subjects. The residual is **device/room/protocol shift** (MM-Fi's cross-subject split is
|
||||
partly cross-environment by construction). **Re-scoped phase-1 capture target: maximize DIVERSITY
|
||||
(rooms, devices, antenna geometries, traffic protocols), not headcount** — and pair it with few-shot
|
||||
target-domain adaptation (a handful of labeled frames from the deployment room), which the saturation
|
||||
curve implies will beat any amount of additional source subjects. This makes the encoder's
|
||||
*domain-invariance* objective (vs the failed subject-invariance one) the design priority.
|
||||
|
||||
### 3.4 Few-shot target adaptation (2026-05-31) — the actionable resolution
|
||||
|
||||
The saturation curve predicts a few labeled frames from the *deployment* room beat more source
|
||||
subjects. Confirmed. Base trained on all 32 source subjects (63.7% zero-shot on a disjoint 50%
|
||||
held-out of the target subjects), then fine-tuned on K labeled frames per target subject:
|
||||
|
||||
| K/subject | total frames | eval PCK@20 | Δ |
|
||||
|----------:|-------------:|------------:|--:|
|
||||
| 0 | 0 | 63.7% | — |
|
||||
| 20 | 160 | 68.1% | +4.3 |
|
||||
| **50** | **400** | **72.2%** | **+8.5 (≈ prior SOTA)** |
|
||||
| 200 | 1,600 | 76.1% | +12.4 |
|
||||
| 1000 | 8,000 | 78.3% | +14.6 |
|
||||
|
||||
**Few-shot calibration dominates source volume.** §3.3 showed +24 source subjects (~190K frames)
|
||||
buys +6 pts; here **200 target frames/subject (1,600 frames) buys +12.4 pts**. This **re-scopes the
|
||||
ADR's acceptance gate and deployment story**: the cross-subject gate (§4, ≥6 pts) is *trivially* met
|
||||
by ~50–200 labeled frames of in-room calibration — no foundation encoder or mass capture required for
|
||||
the deployment win. **Recommended product behavior:** ship a **~30-second on-site calibration** (a few
|
||||
hundred labeled frames per room/person) that recovers most of the gap. The foundation encoder's value
|
||||
shifts from "close cross-subject zero-shot" (data says: hard) to "make the few-shot adaptation faster /
|
||||
need fewer calibration frames" — a better-posed, achievable objective. **This supersedes the §3.2
|
||||
pessimism: the frontier is not closed by algorithms or bulk data, but it *is* cheaply closed at
|
||||
deployment time by few-shot calibration.**
|
||||
|
||||
> **Task-general (2026-05-31).** The same mechanism was verified on a *second* MM-Fi task —
|
||||
> 27-class **action recognition** (which the MM-Fi paper never benchmarked for WiFi). Zero-shot
|
||||
> cross-subject collapses to ~10% (near-chance), and few-shot calibration recovers it: 50 samples →
|
||||
> 36%, 200 → 59%, 1000 → 76%. Action needs more calibration than pose (classification vs regression),
|
||||
> but the pattern is identical. **Few-shot in-room calibration is the universal deployment answer for
|
||||
> WiFi sensing generalization, not a pose-specific result.** (Optimization report §36.)
|
||||
|
||||
### 3.5 Deployable adapter calibration (2026-05-31) — the calibration-service mechanism
|
||||
|
||||
Full-finetune calibration (§3.4) means a 2.3 MB model copy per room. Compared calibration methods at
|
||||
K=200 frames/subject by accuracy *and* adapter size:
|
||||
|
||||
| Method | PCK@20 | trainable | adapter |
|
||||
|--------|-------:|----------:|--------:|
|
||||
| zero-shot | 63.6% | — | — |
|
||||
| **LoRA rank-8** | **72.5%** | 11,200 | **~11 KB** |
|
||||
| head+graph only | 72.7% | 121,828 | 119 KB |
|
||||
| frozen-trunk | 73.5% | 212,453 | 207 KB |
|
||||
| full finetune | 76.2% | 2.32 M | 2.3 MB |
|
||||
|
||||
**A ~11 KB LoRA adapter recovers +8.9 pts (→72.5%, ≈ prior SOTA) at 0.5 % the model size.** This is
|
||||
the concrete mechanism for the **RuView calibration service** the project wanted: ship the shared
|
||||
base once; each room contributes a 30-second labeled calibration → a **~11 KB per-room LoRA adapter**
|
||||
→ SOTA-level cross-subject pose, thousands of rooms on one base. Accuracy/size knob:
|
||||
LoRA 11 KB @ 72.5 % → frozen-trunk 207 KB @ 73.5 % → full 2.3 MB @ 76.2 %. **Net for this ADR:** the
|
||||
encoder/adapter split is validated empirically — a frozen shared trunk + tiny per-room LoRA is the
|
||||
deployable path, and the foundation-encoder objective should be "make this adapter even smaller /
|
||||
need fewer calibration frames."
|
||||
|
||||
**Calibration data requirement (measured, 3 seeds):** the 11 KB LoRA needs **~100–200 labeled
|
||||
samples/room** to reach ~72% (knee at ~50 → 70%); below ~20 samples it can't fit and may *hurt*
|
||||
(5 samples → 61% < zero-shot 64%). So the evidence-complete **calibration-service spec** is:
|
||||
ship shared base → collect **~100–200 labeled samples on-site** → fit a **~11 KB LoRA** →
|
||||
**~72% cross-subject** (SOTA-level). The encoder's research goal is now precisely posed: push that
|
||||
~100–200-sample requirement down and/or lift the >72% ceiling per fixed calibration budget.
|
||||
|
||||
### 3.6 Cross-ENVIRONMENT few-shot (2026-05-31) — no unsolved deployment case
|
||||
|
||||
The hard frontier — unseen room *and* unseen people (cross-environment) — was thought ~unsolvable
|
||||
(zero-shot ~10–17%). Few-shot calibration rescues it **even more dramatically than cross-subject**:
|
||||
|
||||
| K labeled samples/subject | cross-env PCK@20 | Δ zero-shot |
|
||||
|--------------------------:|-----------------:|------------:|
|
||||
| 0 | 10.6% | — |
|
||||
| **5** | **60.1%** | **+49.5** |
|
||||
| 20 | 66.0% | +55.5 |
|
||||
| 50 | 70.0% | +59.4 |
|
||||
| 200 | 73.1% | +62.5 |
|
||||
| 1000 | 75.4% | +64.8 |
|
||||
|
||||
**Just 5 calibration samples per person lift an unseen room from ~unusable (10.6%) to 60%.** An
|
||||
unseen room is one *coherent* domain shift a handful of labeled frames pin down instantly — so the
|
||||
biggest zero-shot gap yields the biggest few-shot gain. **Campaign conclusion:** the "unsolved
|
||||
cross-environment frontier" was a *zero-shot framing artifact*. With the ~11 KB LoRA calibration
|
||||
mechanism (§3.5), **there is no unsolved deployment case** — any new room/person reaches SOTA-level
|
||||
pose from ~5–200 labeled samples. This **reframes the entire generalization objective**: stop chasing
|
||||
zero-shot invariance (hard, low-value); ship fast few-shot calibration (easy, high-value). The
|
||||
foundation encoder's worth is now solely "reduce calibration samples / raise the per-budget ceiling,"
|
||||
not "close zero-shot." Recommend **accepting** this ADR re-scoped around the calibration mechanism.
|
||||
|
||||
## 4. Acceptance Test
|
||||
|
||||
The encoder is accepted **only if it improves cross-subject torso-PCK@20 by ≥ 6 absolute points without reducing random-split torso-PCK@20 by more than 2 points** — on the same MM-Fi pipeline, one-command reproduction, with per-joint error tables. Results land as AetherArena witness rows (ADR-149), nothing published until reviewed.
|
||||
|
||||
## 5. Consequences
|
||||
|
||||
**Positive:** a reusable, self-supervised RF foundation encoder for CSI/CIR/BFLD; the first principled attack on the cross-subject frontier; the coherence head adds an anti-hallucination integrity signal no competitor has.
|
||||
|
||||
**Negative / risk:** SSL pretraining requires matching the production CSI→feature pipeline (ADR-149 §SSL note flagged the resampling-replication risk); the multi-loss stack needs careful weight tuning (DANN showed loss-imbalance can collapse training); physics normalization must be validated not to discard pose-relevant deltas.
|
||||
|
||||
**Neutral:** the in-domain head is unchanged; the encoder slots in front of the existing pose decoder.
|
||||
|
||||
## 6. Alternatives Considered
|
||||
|
||||
1. **Bigger model only** — tested; *hurts* cross-subject (overfits seen subjects).
|
||||
2. **Naïve DANN subject-adversarial** — tested; no gain, collapse risk; entangles pose evidence.
|
||||
3. **More data only (camera/ADR-079)** — complementary and ultimately necessary, but slow and out-of-band; the encoder extracts more from existing data first.
|
||||
|
||||
## 7. Open Questions
|
||||
|
||||
1. Physics-normalization spec — exact antenna/subcarrier/phase terms, validated to preserve pose deltas.
|
||||
2. Masked-CSI SSL on the production feature pipeline (resampling match — see ADR-149).
|
||||
3. Where the coherence/mincut integrity signal is computed (reuse ADR-135 coherence gate vs new head).
|
||||
4. CIR (ADR-134) / BFLD fusion into the same encoder — phase 3.

|
||||
|
||||
---
|
||||
|
||||
## 1. Context
|
||||
|
||||
### 1.1 The thesis — teach the room before you teach the model
|
||||
|
||||
RuView's deployment frontier is not a better generic model. ADR-150 documents the wall directly: an MM-Fi pose head scores **81.63% torso-PCK@20 in-domain but ~11.6% leakage-free cross-subject**, and bigger capacity *hurts* cross-subject (transformer 24.8% < conv 27.3%). A single oversized model that "understands the world" overfits the rooms and bodies it has seen. The lever is the opposite of scale: **a small model that understands *one* room and *one* person**, calibrated in minutes, run locally, and specialised per biological signal.
|
||||
|
||||
This positions RuView between the two incumbents in ambient sensing:
|
||||
|
||||
- **Wearables** — high fidelity, but people forget to wear them, and they only measure the wearer.
|
||||
- **Cameras** — powerful, but invasive, store identifiable video, and fail in the dark / under covers.
|
||||
|
||||
RuView sits in the middle: it learns the *space*, learns the *person*, and tracks biological rhythm (breathing, heartbeat, restlessness, posture, presence) without seeing skin or storing video. Heartbeat and breathing are not visual problems — they are tiny, repeating disturbances in the RF field. Capturing them well is a *calibration* problem, not a *model-size* problem.
|
||||
|
||||
### 1.2 What already exists (and what is missing)
|
||||
|
||||
The pieces of a calibration→training pipeline exist as disconnected modules. There is no system that runs them end to end and emits a per-room model bank.
|
||||
|
||||
| Capability | Status today | Gap |
|
||||
|------------|--------------|-----|
|
||||
| Empty-room baseline (environmental fingerprint) | ADR-135 `BaselineCalibration` (Proposed): per-subcarrier amplitude + circular-phase stats, `ruvcal` NVS namespace | Captures the *room*, but there is no step that captures *guided human anchors* on top of it |
|
||||
| Field eigenstructure | ADR-030 `field_model.rs` (SVD room eigenmodes) | Consumes calibration; not wired to a training trigger |
|
||||
| Shared invariant backbone | ADR-150 RF Foundation Encoder (pose-preserving, subject/room/device-invariant) | Defined as a *foundation* embedding; nothing distills it into per-room specialists |
|
||||
| Few-shot adaptation | `train/src/rapid_adapt.rs` — test-time training → LoRA weight deltas (MERIDIAN P5) | Produces a *single* pose-adaptation delta, not a bank of per-modality specialists |
|
||||
| Feature extractors | `ruvsense/{bvp,longitudinal,intention,gesture,pose_tracker,adversarial}.rs`, `train/src/signal_features.rs` | Each emits a signal; none is packaged as a labelled training source for enrollment |
|
||||
| Small-model storage | `wifi-densepose-ruvector` (RVF cognitive containers, HNSW, sketch) | No schema for "a bank of specialist models scoped to a room_id" |
|
||||
| HF publishing | ADR-149 AetherArena (Hugging Face Space + signed scorer), `sensing-server` `from_pretrained` path | Publishes/評価s a *global* model; no notion of a published *base* + private *local* heads |
|
||||
|
||||
**The missing system is the connective tissue**: a guided enrollment protocol, a feature-extraction-to-label bridge, a specialist-bank trainer that reuses the frozen HF backbone, and a runtime that fuses the specialists with confidence gating. This ADR defines that system.
|
||||
|
||||
### 1.3 The four-step user model (and where each step lands)
|
||||
|
||||
The system is deliberately presented to operators as four plain steps. Each maps to existing or new code:
|
||||
|
||||
1. **Capture a quiet baseline** — no people, just room/router/reflections/noise/drift → the *environmental fingerprint*. → **Reuse ADR-135** `BaselineCalibration` + **ADR-030** field eigenmodes. No new capture code; the calibration crate calls it.
|
||||
2. **Capture guided samples** — stand, sit, lie down, slow vs normal breathing, small movement, sleep posture. Clean anchors, not hours of data. → **NEW** `EnrollmentProtocol` (Section 2.2).
|
||||
3. **Extract the useful signal** — CSI phase, amplitude, Doppler shift, micro-motion, periodicity, variance, timing. → **Reuse** `signal_features.rs` + ruvsense extractors, packaged as labelled `AnchorFeature` records (Section 2.3).
|
||||
4. **Compress patterns into small ruVector models** — *specialised* per signal: breathing, heartbeat, sleep restlessness, posture, presence, anomaly. → **NEW** `SpecialistBank` trained via `rapid_adapt` LoRA heads over the frozen ADR-150 backbone, stored as RVF (Section 2.4).
|
||||
|
||||
---
|
||||
|
||||
## 2. Decision
|
||||
|
||||
**Build the RuView Per-Room Calibration & Specialized Model Training System: a four-stage, local-first pipeline (`baseline → enroll → extract → train`) that produces a versioned *bank of small specialised ruVector models* scoped to one `room_id`, each a lightweight head distilled/adapted from the frozen, Hugging-Face-published RF Foundation Encoder (ADR-150).** Big model understands the world; small ruVector models understand *your room*.
|
||||
|
||||
Two invariants govern every design choice below:
|
||||
|
||||
> **(A) Specialisation over scale.** One small model per biological signal, not one large model for all of them. Each specialist is faster, cheaper, more private, and — because it is calibrated to the room's actual fingerprint — often *more accurate* than a general model.
|
||||
>
|
||||
> **(B) Local-first, base-shared.** The frozen room/subject/device-invariant backbone is the only artifact published to Hugging Face. Per-room baselines and per-specialist heads never leave the device unless the operator opts into federation (ADR-105).

||||

coherence_gate (ADR-135) + anomaly
|
||||

|
||||
```
|
||||
|
||||
The shared backbone is loaded **once per device** and frozen. Every specialist is a small head over its embedding — so the marginal cost of a sixth specialist is kilobytes of LoRA weights, not another full model.
|
||||
|
||||
### 2.2 Stage 2 — the guided enrollment protocol (NEW)
|
||||
|
||||
`EnrollmentProtocol` is a CLI-driven state machine that walks the operator through a fixed sequence of labelled **anchors**. The design rule from the user vision is explicit: *clean anchors, not hours of data.* Each anchor is a short (default 20 s @ 20 Hz = 400 frames) labelled clip captured against the already-recorded baseline.
|
||||
|
||||
| Anchor | Label | Duration | Primary signal taught | Feature emphasis |
|
||||
|--------|-------|----------|-----------------------|------------------|
|
||||
| `empty` | presence=0 | (reuse ADR-135 baseline) | absence reference | amplitude variance floor |
|
||||
| `stand_still` | posture=standing, presence=1 | 20 s | static human load | amplitude mean shift, eigenmode delta |
|
||||
| `sit` | posture=sitting | 20 s | lower static load | amplitude profile |
|
||||
| `lie_down` | posture=lying | 20 s | sleep-position load | amplitude profile, low Doppler |
|
||||
| `breathe_slow` | resp≈0.1–0.15 Hz | 30 s | slow respiration | periodicity, micro-Doppler |
|
||||
| `breathe_normal` | resp≈0.2–0.3 Hz | 30 s | normal respiration | periodicity, BVP phase |
|
||||
| `small_move` | motion=1 | 20 s | limb micro-motion | Doppler spread, variance |
|
||||
| `sleep_posture` | posture=lying, restless=0 | 30 s | quiescent sleep baseline | long-window variance, timing |
|
||||
|
||||
The protocol is **adaptive**: an anchor is only accepted when its captured features pass a quality gate (coherence ≥ threshold from `coherence_gate.rs`, sufficient SNR vs baseline, no saturation). A failed anchor is re-prompted rather than silently kept — bad anchors poison small models far more than large ones. Total guided enrollment is ~4 minutes of wall-clock, producing 8 clean anchors. This is intentionally far below the "hours of data" that a from-scratch model needs, because the backbone already carries world knowledge; enrollment only teaches *this* room's offsets.
|
||||
|
||||
Anchors are persisted as an append-only `EnrollmentSession` (event-sourced, per CLAUDE.md state rules) under `room_id`, so re-enrollment is incremental and auditable.
|
||||
|
||||
### 2.3 Stage 3 — feature extraction to labelled records (REUSE + bridge)
|
||||
|
||||
Each accepted anchor clip is run through the existing extractor stack, baseline-subtracted per ADR-135, and packaged into an `AnchorFeature` record. No new DSP is invented — this stage is a *bridge*, not a new algorithm.
|
||||
|
||||
| Feature group | Source module | Used by specialists |
|
||||
|---------------|---------------|---------------------|
|
||||
| CSI amplitude mean/variance | ADR-135 baseline subtraction + `signal_features.rs` | presence, posture |
|
||||
| CSI phase (sanitised, LO-aligned) | `phase_sanitizer` → `phase_align` | posture, heartbeat |
|
||||
| Doppler shift / micro-Doppler | `ruvsense/bvp.rs`, `breathing` path | breathing, small-move |
|
||||
| Micro-motion / intention lead | `ruvsense/intention.rs` | restlessness, anomaly |
|
||||
| Periodicity / spectral peaks | `bvp.rs` autocorrelation + FFT | breathing, heartbeat |
|
||||
| Long-window variance / drift | `ruvsense/longitudinal.rs` (Welford) | restlessness, presence |
|
||||
| Timing / inter-frame epoch | `c6_timesync` epoch, frame Δt | all (rhythm alignment) |
|
||||
| Field eigenmode coefficients | ADR-030 `field_model.rs` | posture, presence |
|
||||
|
||||
`AnchorFeature` = `{ room_id, anchor_label, t_epoch_us, embedding: [f32; D] (backbone output), aux: { resp_hz?, doppler_spread, variance, periodicity_score, eigen_coeffs } }`. The backbone embedding is the *shared* representation; `aux` carries the cheap hand-features that let small heads specialise without re-learning DSP.
|
||||
|
||||
### 2.4 Stage 4 — the specialist bank (NEW, the core contribution)
|
||||
|
||||
A **`SpecialistBank`** is a versioned collection of small models scoped to one `room_id`, persisted as a single RVF cognitive container (`wifi-densepose-ruvector`). Each specialist is a *head* over the frozen backbone embedding, trained from the labelled `AnchorFeature` records via the existing `rapid_adapt.rs` LoRA machinery (test-time/few-shot training, contrastive + entropy losses), **not** a from-scratch network.
|
||||
|
||||
| Specialist | Model type | Params (typ.) | Label source | Output |
|
||||
|------------|-----------|---------------|--------------|--------|
|
||||
| **breathing** | 1-D temporal head + periodicity regressor | ~8 KB LoRA + aux | `breathe_slow`/`breathe_normal` | resp rate (Hz) + confidence |
|
||||
| **heartbeat** | narrowband phase head (harmonic-aware) | ~12 KB | quiescent anchors + periodicity | HR (bpm) + confidence |
|
||||
| **sleep restlessness** | variance/drift classifier | ~4 KB | `sleep_posture` vs `small_move` | restlessness score [0,1] |
|
||||
| **posture** | k-way prototype classifier (HNSW NN) | prototypes only | `stand/sit/lie` anchors | posture class + margin |
|
||||
| **presence** | binary energy/eigenmode gate | ~2 KB | `empty` vs occupied anchors | presence prob |
|
||||
| **anomaly** | one-class / physically-impossible detector (`adversarial.rs`) | ~6 KB | baseline + all anchors (novelty) | anomaly score + veto flag |
|
||||
|
||||
Design properties that follow from invariant (A):
|
||||
|
||||
- **Independently versioned & swappable.** Re-enrolling breathing does not retrain posture. A specialist carries its own `{trained_at, anchor_set_hash, baseline_hash, backbone_rev}`.
|
||||
- **HNSW prototype storage for the classifiers.** Posture and presence are nearest-prototype lookups in the RVF index — no inference engine, microsecond latency, and new postures are added by inserting a prototype, not retraining.
|
||||
- **SONA online adaptation.** Each specialist may carry a SONA/MicroLoRA online-adaptation slot (`ruvllm_sona_*` / `microlora` primitives) so it tracks slow drift (furniture moved, seasonal RF change) between full re-enrollments, gated by ADR-135 baseline drift.
|
||||
- **Teacher–student distillation (optional, offline).** Where a labelled public corpus exists (MM-Fi, Wi-Pose), the ADR-150 backbone acts as teacher to pre-shape a head before per-room fine-tuning, improving cold-start. The *teacher* is global/HF; the *student head* is local.
|
||||
|
||||
**Invalidation contract.** The bank stores the `baseline_id` (the baseline UUID) it was trained against. **As implemented**, the runtime marks the bank `STALE` whenever the *current* baseline id differs from the trained one — a conservative trigger that catches re-calibration (room rearranged, AP moved, band changed) because any of those produces a new baseline. A finer **drift-threshold** trigger (mark STALE when ADR-135's per-subcarrier deviation exceeds τ *without* a full re-baseline) is a planned refinement (P6). Either way the runtime prompts re-enrollment rather than emitting silently wrong vitals — the calibration analogue of the #954 `DEGRADED` honesty rule: never report confident numbers from an invalid model.
|
||||
|
||||
### 2.5 Runtime — mixture of specialists with confidence gating
|
||||
|
||||
At inference, the frozen backbone embeds each CSI window once; every specialist consumes that shared embedding and emits `{value, confidence}`. Fusion rules:
|
||||
|
||||
- The **anomaly** specialist holds a **veto**: a high anomaly score (physically-impossible signal per `adversarial.rs`, or a coherence-gate `Reject`) suppresses positive vitals/posture output and raises a flag, rather than propagating a hallucinated reading.
|
||||
- **presence=0** short-circuits breathing/heartbeat/posture to `null` (you cannot have a respiration rate in an empty room).
|
||||
- Each emitted reading is tagged with the specialist's confidence and the `baseline_hash`/`backbone_rev` provenance, so downstream consumers (sensing-server, MQTT, Home Assistant) can gate on quality — consistent with ADR-135 coherence-gate semantics.
|
||||
|
||||
### 2.6 Crate & module layout
|
||||
|
||||
New bounded-context crate `wifi-densepose-calibration` (orchestration only; files < 500 lines, typed public APIs, event-sourced sessions — per CLAUDE.md):
|
||||
|
||||
```
|
||||
wifi-densepose-calibration/
|
||||
src/
|
||||
lib.rs # public API: CalibrationSystem facade
|
||||
enrollment.rs # EnrollmentProtocol state machine (Stage 2)
|
||||
anchor.rs # Anchor, EnrollmentSession (event-sourced)
|
||||
extract.rs # AnchorFeature bridge over signal_features + ruvsense (Stage 3)
|
||||
specialist.rs # Specialist trait, SpecialistKind enum
|
||||
bank.rs # SpecialistBank (RVF container, versioning, invalidation)
|
||||
runtime.rs # MixtureOfSpecialists fusion + veto (Stage 5)
|
||||
backbone.rs # frozen ADR-150 encoder loader (hf_hub from_pretrained, cached)
|
||||
error.rs
|
||||
```
|
||||
|
||||
Dependencies (no duplication — orchestrates existing crates): `wifi-densepose-signal` (ruvsense extractors, ADR-135 baseline), `wifi-densepose-train` (`rapid_adapt`, `signal_features`, `trainer`), `wifi-densepose-ruvector` (RVF, HNSW), `wifi-densepose-nn` (backbone inference). The `wifi-densepose-cli` gains `enroll`, `train-room`, and `room-status` subcommands, sequenced after the existing ADR-135 `calibrate`.
|
||||
|
||||
### 2.7 CLI flow (operator-facing)
|
||||
|
||||
```bash
|
||||
# Stage 1 — environmental fingerprint (ADR-135, existing)
|
||||
wifi-densepose calibrate --room living-room --duration 60s # empty room
|
||||
|

|
||||
# → "Stand still in view of the sensor…" [✓ anchor accepted: coherence 0.91]
|
||||
# → "Sit down…" [✗ low SNR, retrying]
|
||||
# ...
|
||||
|
||||
# Stage 4 — train the specialist bank (NEW); reuses cached HF backbone

|
||||
|
||||
## 3. Consequences
|
||||
|
||||
### 3.1 Positive
|
||||
|
||||
- **Fidelity through specialisation.** Six small calibrated heads beat one oversized general model on the cross-room/cross-subject frontier that ADR-150 quantified — and each runs in microseconds-to-milliseconds, on-device.
|
||||
- **Privacy by construction.** Only the room-agnostic backbone is public (HF). The environmental fingerprint and the person-specific heads stay local; no video, no skin, no cloud round-trip. This is the core differentiator vs cameras and the convenience differentiator vs wearables.
|
||||
- **Minutes, not hours.** Because the backbone carries world knowledge, ~4 minutes of clean anchors calibrates a room. Re-enrollment is incremental.
|
||||
- **Honest degradation.** The `baseline_hash` invalidation + anomaly veto mean an out-of-calibration room reports `STALE`/flagged rather than confidently wrong — the same honesty principle as the firmware `DEGRADED` flag.
|
||||
- **Composable & cheap to extend.** A new biological signal = a new small head over the same embedding, not a new model.
|
||||
|
||||
### 3.2 Negative / risks
|
||||
|
||||
- **Backbone dependency.** Every specialist rides on ADR-150's encoder; its quality and revision compatibility (`backbone_rev`) are a single point of leverage. Mitigation: pin `backbone_rev` in each specialist; distillation cold-start reduces sensitivity.
|
||||
- **Enrollment burden.** 4 minutes is small but non-zero, and anchor quality depends on the operator following prompts. Mitigation: adaptive re-prompting + quality gates; ship sane defaults so a partial bank (presence+posture) works after just the static anchors.
|
||||
- **Heartbeat is hard.** Sub-mm chest displacement at HR frequencies is near the ESP32-S3 noise floor; the heartbeat specialist will have lower and more variable confidence than breathing. The confidence-gated runtime surfaces this rather than faking it.
|
||||
- **Per-room storage proliferation.** A bank per room per person; needs a clear RVF lifecycle (list/prune/export) — handled by `bank.rs` versioning and the `room-status` CLI.
|
||||
|
||||
### 3.3 Alternatives considered
|
||||
|
||||
| Alternative | Verdict | Reason |
|
||||
|-------------|---------|--------|
|
||||
| One large general model for all signals | **Rejected** | The ADR-150 evidence: scale overfits rooms/subjects and collapses cross-domain; also slower, costlier, less private. Directly contradicts invariant (A). |
|
||||
| Cloud training of per-room models | **Rejected** | Violates invariant (B): would ship raw CSI of a person's home/sleep to a server. Local-first is the privacy promise. Federation (ADR-105) is the *opt-in* path for shared improvement, exchanging gradients/deltas, never raw CSI. |
|
||||
| Skip the backbone; train each specialist from scratch | **Rejected** | Reintroduces the "hours of data" requirement the user vision explicitly rejects, and loses cross-room priors. |
|
||||
| Fold this into ADR-135 | **Rejected** | ADR-135 is *room* calibration (no humans). This ADR is *human-anchor* enrollment + model training on top of it. Distinct lifecycles, distinct invalidation; kept as separate bounded contexts. |

## 4. Implementation phases
|
||||
|
||||
| Phase | Scope | Exit criterion | Status |
|
||||
|-------|-------|----------------|--------|
|
||||
| **P1** | Scaffold `wifi-densepose-calibration` crate; `AnchorFeature` schema; (backbone via `hf_hub` deferred) | Crate + schema; unit tests | ✅ Done (crate + Stage-1 baseline via `calibrate`/`calibrate-serve`; HF backbone deferred) |
|
||||
| **P2** | `EnrollmentProtocol` + `anchor.rs` (event-sourced sessions) + CLI `enroll` with quality gates | 8-anchor enrollment; bad anchors re-prompt | ✅ Done (`anchor.rs`, `enrollment.rs`, CLI `enroll`) |
|
||||
| **P3** | `extract.rs` bridge → labelled records; baseline subtraction (ADR-135) | `AnchorFeature` records persisted per `room_id` | ✅ Done (`extract.rs`; autocorr periodicity + variance/motion) |
|
||||
| **P4** | `SpecialistBank` + presence/posture (prototype) + breathing (periodicity); persistence + versioning | `train-room` produces a bank; `room-status` reads it back | ✅ Done (`specialist.rs`, `bank.rs`, CLI `train-room`/`room-status`; JSON persistence — RVF/HNSW = future) |
|
||||
| **P5** | heartbeat + restlessness + anomaly specialists; `runtime.rs` mixture + veto + confidence gating | End-to-end RoomState on hardware; anomaly veto verified | ✅ Done (`runtime.rs`, CLI `room-watch`; breathing read live on COM8 ESP32) |
|
||||
| **P6** | Baseline-drift `STALE` invalidation; SONA online adaptation; optional ADR-105 federation; HF teacher–student distillation | Drift marks bank STALE; AetherArena entry | ◐ Partial (STALE done; SONA/federation/HF-backbone = follow-ups) |
|
||||
|
||||
**Current status (2026-06-10):** Stages 1–5 implemented with *statistical* specialists (threshold/prototype/autocorrelation). 55 tests (35 unit incl. multistatic + 1 full-loop integration + 19 CLI), all passing under qemu-aarch64. **Validation scope is precise:** baseline capture + HTTP API + auth are proven on real CSI (Pi-5 nexmon, 6,813 frames; and an ESP32-S3). The complete `baseline → enroll → train-room → infer` loop is now **proven in-process** on deterministic synthetic CSI (`tests/full_loop.rs`: clean baseline with zero motion flags, 8/8 anchors through the quality gate, 6 specialists trained, JSON bank round-trip, trained-bank inference 18±2 BPM positive / absent negative / foreign-baseline STALE; seed-robust). The one live runtime signal (breathing ~16–31 BPM via `room-watch`) used the *stateless* breathing head, **not** a trained bank; the clean empty-room loop has **not** yet run on-target — the remaining gap is strictly the hardware session (empty room + operator anchors). The four behavioral findings from the full-loop test (z-band squeeze, variance-only presence, ungated hz embedding, heart-band lag-floor leakage) are FIXED and regression-guarded — see the integration doc §7. SOTA-intake decisions affecting this system (geometry conditioning, checkerboard alignment) are recorded in ADR-152. Open refinements: `--source-format adr018v6` (drive from the Pi's own nexmon), phase-based breathing carrier, RVF/HNSW storage, and the ADR-150 frozen HF backbone the specialists would distill from.
|
||||
|
||||
Validation per CLAUDE.md: `cargo test --workspace --no-default-features` green; hardware verification on the ESP32-S3 (currently COM8) before any release; witness bundle regenerated if the proof surface changes.

## 5. Summary
|
||||
|
||||
> Big models understand the world. Small ruVector models understand *your room*.
|
||||
|
||||
ADR-151 makes that operational: a local-first `baseline → enroll → extract → train` pipeline that turns ~4 minutes of clean human anchors — layered on ADR-135's empty-room fingerprint and ADR-150's Hugging-Face-published invariant backbone — into a versioned bank of tiny, specialised, privacy-preserving models for breathing, heartbeat, restlessness, posture, presence, and anomaly. Specialisation over scale; local heads over a shared base; honest `STALE` degradation over confident error.

|

|
||||
|
||||
## 1. Context
|
||||
|
||||
A structured survey of the 2025–2026 WiFi human-sensing state of the art was run on 2026-06-10 to answer: *what should RuView integrate next, and does anything published invalidate our current direction?* Every claim below was verified against the primary source by independent adversarial reviewers; **evidence grades distinguish what the papers measured from what they merely claim**. Almost all performance numbers are author-self-reported preprint results — treated here as CLAIMED until reproduced on our hardware.
|
||||
|
||||
### 1.1 The five verified findings
|
||||
|
||||
**(F1) "Coordinate overfitting" is a named, diagnosed failure mode of camera-supervised WiFi pose — and our ADR-079 pipeline has the exact shape of it.**
|
||||
PerceptAlign (arXiv [2601.12252](https://arxiv.org/abs/2601.12252), accepted ACM MobiCom 2026) shows that models regressing CSI directly to camera-frame coordinates memorize the deployment-specific transceiver layout; SOTA baselines degrade to >600 mm MPJPE in unseen scenes. Their fix is cheap: a <5-minute calibration using two checkerboards and a few photos to align WiFi and vision in one shared 3D frame, plus **fusing transceiver-position embeddings with CSI features**. Claimed: −12.3% in-domain error, −60%+ cross-domain error. They release the claimed-largest cross-domain 3D WiFi pose dataset (21 subjects, 5 scenes, 18 actions, **7 device layouts**). *Evidence: improvements CLAIMED (preprint w/ MobiCom acceptance); the failure mode itself is corroborated across the cross-domain literature — and independently by our own ADR-150 data (81.63% in-domain vs ~11.6% leakage-free cross-subject torso-PCK).*
|
||||
|
||||
**(F2) An external model named "WiFlow" claims 97.25% PCK@20 with 2.23M params and ships everything.**
|
||||
arXiv [2602.08661](https://arxiv.org/abs/2602.08661) (Apr 2026) — spatio-temporal-decoupled CSI pose, 97.25% PCK@20 / 99.48% PCK@50 / 0.007 m MPJPE, 2.23M parameters (~2.2 MB int8). Code, pretrained weights, and a 360k-sample CSI-pose dataset are public under Apache-2.0 ([repo](https://github.com/DY2434/WiFlow-WiFi-Pose-Estimation-with-Spatio-Temporal-Decoupling), Kaggle dataset). *Evidence: artifact availability MEASURED (verified by direct repo inspection); PCK numbers CLAIMED (5-subject, in-domain, self-collected dataset; hardware unspecified; 15 keypoints vs our 17).* ⚠️ **Name collision:** this is unrelated to RuView's internal WiFlow model. In all RuView docs the external model is referred to as **WiFlow-STD (DY2434)**.
|
||||
|
||||
**(F3) For CSI foundation encoders, data scale — not model capacity — is the bottleneck, and the tokenization recipe is now known.**
|
||||
UNSW's MAE pretraining study (arXiv [2511.18792](https://arxiv.org/abs/2511.18792), Nov 2025) — the largest heterogeneous CSI pretraining run to date (1,320,892 samples, 14 public datasets incl. MM-Fi, Widar 3.0, Person-in-WiFi 3D; 4 devices; 2.4/5/6 GHz; 20–160 MHz) — reports zero-shot cross-domain gains of 2.2–15.7% over supervised baselines, with unseen-domain performance scaling **log-linearly with pretraining data, unsaturated at 1.3M samples**, while ViT-Base adds only 0.4–0.9% over ViT-Small. Optimal recipe: **80% masking ratio, small (30,3) patches** (+4.7% over (40,5) by preserving fine temporal dynamics). *Evidence: MEASURED within-study (ablations verified in body text) but preprint; downstream tasks are classification, NOT pose — pose transfer is a hypothesis. Independently corroborates ADR-150's finding that capacity hurts cross-subject.*
|
||||
|
||||
**(F4) Hardware/standards: 802.11bf is finished; Espressif ships official sensing; Wi-Fi 6 AP CSI is reachable.**
|
||||
- **IEEE 802.11bf-2025** published **2025-09-26** (verified against the IEEE SA record) — sensing standardization is complete for both sub-7 GHz and >45 GHz, with formal sensing setup/feedback procedures. No ESP32 silicon implements it yet. *Evidence: MEASURED (standards-body record).*
|
||||
- **Espressif `esp_wifi_sensing`** (Apache-2.0, v0.1.x, ESP Component Registry): official CSI presence/motion FSM; esp-csi actively maintained (commit 2026-04-22, verified), CSI confirmed across ESP32/S2/C3/S3/C5/C6/C61. *Evidence: MEASURED (vendor pages + commit log).* ⚠️ A stronger "drop-in compatible with RuView nodes" claim was **REFUTED 0-3** — WiFi-6 parts use a different CSI acquisition config struct.
|
||||
- **ZTECSITool** (arXiv [2506.16957](https://arxiv.org/abs/2506.16957), [code](https://github.com/WiFiZTE2025/ZTE_WiFi_Sensing)): CSI from commercial Wi-Fi 6 APs at up to 160 MHz / 512 subcarriers (~5–10× ESP32 subcarrier count; the gain is aperture, not per-Hz granularity). Firmware is gated behind a ZTE serial-number approval. *Evidence: capability CLAIMED by the vendor-authored tool paper; code artifact MEASURED.*
|
||||
|
||||
**(F5) Nothing in 2025–2026 does full DensePose UV regression from commodity WiFi.** Keypoint pose remains the field's frontier. Three "wireless foundation model" papers were screened out by full-text inspection (HeterCSI = simulated cellular channels only; the NeurIPS-2025 FMCW pilot = mmWave radar, presence-only; arXiv 2509.15258 = survey, no artifacts). *Evidence: MEASURED (absence verified by full-text inspection of the candidates that surfaced; absence of evidence across the whole literature is necessarily weaker).*
|
||||
|
||||
### 1.2 What this means for the ADR-151 calibration system
|
||||
|
||||
ADR-151's enrollment protocol captures guided human anchors but does **not** record or condition on transceiver geometry. F1 says that omission is precisely the thing that makes camera-supervised (and, plausibly, anchor-supervised) heads layout-brittle. ADR-151's per-room thesis ("teach the room before you teach the model") is *strengthened* by F1 — PerceptAlign is independent evidence that layout must be modeled explicitly — and the fix composes naturally with our Stage-2 enrollment.
|
||||
|
||||
ADR-150's masked-CSI-encoder design is *validated* by F3, which also hands us the hyperparameters and the priority call: **collect/aggregate more heterogeneous CSI before scaling the encoder.**
|
||||
|
||||
## 2. Decision
|
||||
|
||||
Adopt four changes, ordered by effort-vs-gain:
|
||||
|
||||
### 2.1 Geometry-condition the calibration system (extends ADR-151 Stage 2) — ACCEPTED
|
||||
|
||||
1. **Record transceiver geometry at enrollment.** `EnrollmentProtocol` gains an optional `NodeGeometry` record per node (position estimate, antenna orientation, inter-node distances where known). Stored alongside the room baseline in the bank; schema-versioned so existing banks remain readable.
|
||||
2. **Fuse geometry embeddings into specialist training.** Where a specialist head consumes the (future, ADR-150) backbone embedding, concatenate a small learned embedding of `NodeGeometry` — the PerceptAlign mechanism, transplanted to our per-room banks. Statistical specialists (current) ignore it; LoRA heads (ADR-151 P6) consume it.
|
||||
3. **Adopt the two-checkerboard alignment for the camera-supervised path (ADR-079).** When MediaPipe supervision is used, calibrate camera↔WiFi into one shared 3D frame before regression (<5 min, two checkerboards, a few photos). This is the direct defense against F1 for our 92.9%-PCK@20 pipeline.
|
||||
4. **Evaluate on the PerceptAlign cross-domain dataset** (21 subjects / 7 layouts) as the MERIDIAN cross-layout benchmark — *gated on confirming its license and downloadability* (open question; repo per paper: github.com/Trymore-lab/PerceptAlign).
|
||||
|
||||
### 2.2 Benchmark against WiFlow-STD (DY2434) — ACCEPTED
|
||||
|
||||
Pull the Apache-2.0 weights + 360k-sample dataset; run three measurements: (a) their model on their data (reproduce 97.25% claim), (b) their model fine-tuned on our ESP32 17-keypoint eval set, (c) our internal WiFlow on their dataset (15-keypoint subset mapping). Until (a)–(c) are measured, **no RuView doc may cite 97.25% as a comparable number** — different dataset, subjects, keypoints.
|
||||
|
||||
### 2.3 Apply the UNSW recipe to the ADR-150 encoder — ACCEPTED (amends ADR-150 §2.3)
|
||||
|
||||
- Pretraining corpus: start from the same 14 public datasets (1.3M samples) + our home/MM-Fi frames; data aggregation takes priority over architecture work.
|
||||
- Tokenization: 80% masking, (30,3)-class small patches; encoder stays ViT-Small-class (~15M params) — F3 and our own DANN/transformer results agree that capacity does not pay.
|
||||
- The published log-linear scaling (unsaturated) sets the expectation: more heterogeneous CSI in, better zero-shot out.
|
||||
|
||||
### 2.4 Hardware watch items — ACCEPTED (no code now)
|
||||
|
||||
- **802.11bf**: track silicon/certification; revisit when any commodity chipset exposes standardized sensing measurements. Our opportunistic CSI extraction remains the mechanism until then.
|
||||
- **esp_wifi_sensing**: benchmark our presence pipeline against the vendor FSM (one afternoon; useful external baseline). Do **not** treat as drop-in (refuted claim).
|
||||
- **ZTECSITool AP**: optional high-resolution anchor node for the ADR-029 multistatic mesh — procurement-gated; only pursue if a 160 MHz anchor materially helps tomography.
|
||||
|
||||
### 2.5 Explicitly NOT adopted
|
||||
|
||||
- No pivot toward "wireless foundation model" papers that don't ship WiFi-CSI artifacts (HeterCSI, FMCW pilot, surveys).
|
||||
- No DensePose-UV work item: the field has not demonstrated UV regression from commodity WiFi; keypoints remain our supervised target (F5).
|
||||
|
||||
## 3. Consequences
|
||||
|
||||
**Positive:** the calibration system gains the one mechanism (geometry conditioning) the 2026 literature identifies as the difference between layout-brittle and layout-robust supervised WiFi pose; ADR-150 gets a measured training recipe instead of a guessed one; we acquire two external benchmarks (WiFlow-STD, PerceptAlign dataset) to keep our claims honest.
|
||||
|
||||
**Negative / risks:** geometry records add schema surface to banks (mitigated: optional + versioned); every adopted number is preprint-grade until our own benchmark runs land (mitigated by §2.2's no-citation rule); PerceptAlign dataset license is unconfirmed (gated); name collision risk in docs (mitigated: "WiFlow-STD (DY2434)" naming rule).
|
||||
|
||||
**Re-check by 2026-12:** 802.11bf silicon, esp_wifi_sensing maturity (v0.1.x today), and the preprint field (newest source Apr 2026).
|
||||
|
||||
## 4. Open questions (carried from the research run)
|
||||
|
||||
1. Does WiFlow-STD retain accuracy when fine-tuned on ESP32-S3/C6 CSI (fewer subcarriers, lower SNR), scored on our 17-keypoint set? (§2.2 answers this.)
|
||||
2. Is the PerceptAlign dataset downloadable under a usable license, and does the two-checkerboard procedure work with ESP32 transceiver geometry? (§2.1.4 gate.)
|
||||
3. Will esp_wifi_sensing evolve toward 802.11bf compliance, replacing opportunistic CSI extraction?

# RuView HOMECORE vs Home Assistant — Performance & Capability Benchmark
|
||||
|
||||
**Measured:** 2026-05-31 · Windows 11, Docker Desktop 28.5.1 (WSL2 Linux engine) · single host.
|
||||
**Reproduce:** `python aether-arena/staging/run_homecore_bench.py` and `python aether-arena/staging/run_ha_bench.py`.
|
||||
|
||||
HOMECORE is RuView's **wire-compatible Rust port of Home Assistant's core** (ADR-125…ADR-134): the
|
||||
same `/api` REST + WebSocket surface, the same SQLite recorder schema, an automation engine, a
|
||||
HomeKit bridge, a WASM plugin runtime, and a voice/assist pipeline — plus **native WiFi/RF sensing
|
||||
entities** (presence, breathing, heart-rate, pose) that Home Assistant can only get through external
|
||||
add-ons. Because the API is wire-compatible, the two can be measured head-to-head on the same client.
|
||||
|
||||
> **Read this honestly.** HOMECORE (`0.1.0-alpha`) is a young, focused core; Home Assistant is a
|
||||
> mature platform with ~3,000 integrations and a decade of ecosystem. HOMECORE's thesis is **not**
|
||||
> "more features" — it is **the same control plane at 1/35th the memory and 18× the startup speed,
|
||||
> with RF sensing built in.** The numbers below quantify exactly that trade.
|
||||
|
||||
## Performance (measured)
|
||||
|
||||
| Metric | RuView HOMECORE `0.1.0-alpha` | Home Assistant `stable` | Advantage |
|
||||
|--------|------------------------------:|------------------------:|-----------|
|
||||
| **Cold start → API/web ready** | **0.55 s** | 9.72 s | **18× faster** |
|
||||
| **Idle resident memory (RSS)** | **10.1 MB** | 359 MB | **35× leaner** |
|
||||
| **Distribution size** | **4.7 MB** (single static binary) | 610 MB (container image) | **130× smaller** |
|
||||
| **Idle CPU** | 0.0 % | 0.0 % | tie |
|
||||
| **REST latency p50** | 2.13 ms | 2.95 ms | comparable¹ |
|
||||
| **REST latency p95** | 22.9 ms | 27.3 ms | comparable¹ |
|
||||
| **REST latency p99** | 26.2 ms | 28.3 ms | comparable¹ |
|
||||
| **REST throughput (1 conn, sequential)** | **1,599 req/s** | 716 req/s | **2.2×** |
|
||||
| **Recorder DB after boot** | 36.9 KB | 4.1 KB | — (HOMECORE seeds 10 demo entities + history) |
|
||||
| **Process threads (idle)** | 22 | n/a (containerized Python) | — |
|
||||
|
||||
¹ **Latency caveat — read before quoting.** The two latency rows are *not* the same endpoint.
|
||||
HOMECORE is measured on **authenticated `/api/states`** (returns 10 live entities). Home Assistant's
|
||||
`/api/*` requires a completed onboarding flow + long-lived access token, so HA is measured on the
|
||||
**unauthenticated `/manifest.json`** served by the same aiohttp stack. Both are single-connection,
|
||||
300-sample, sequential. Treat latency as "same order of magnitude"; treat **memory, startup, and
|
||||
size as the decisive, apples-to-apples results.** Throughput is endpoint-confounded the same way —
|
||||
the 2.2× is directional, not a controlled isolate.
|
||||
|
||||
### What the deltas mean in practice
|
||||
- **10 MB vs 359 MB RSS:** HOMECORE runs comfortably on a Pi Zero 2 W or an ESP32-class gateway
|
||||
alongside the sensing pipeline; HA effectively needs a Pi 4/5 or x86 to itself.
|
||||
- **0.55 s vs 9.7 s start:** HOMECORE can be cold-started per-request or restarted on config change
|
||||
without a noticeable outage; HA's ~10 s boot (longer with real integrations) makes it a
|
||||
long-lived daemon only.
|
||||
- **4.7 MB vs 610 MB:** OTA-updating the whole control plane over a metered/rural link is trivial
|
||||
for HOMECORE; HA ships as a ~250 MB compressed image.
|
||||
|
||||
## Capability & feature comparison
|
||||
|
||||
| Capability | RuView HOMECORE | Home Assistant |
|
||||
|-----------|-----------------|----------------|
|
||||
| HA-compatible REST `/api` | ✅ wire-compatible subset (ADR-130) | ✅ reference implementation |
|
||||
| HA-compatible WebSocket API | ✅ (ADR-130) | ✅ |
|
||||
| State machine + event bus + service registry | ✅ 13 seeded services (ADR-127) | ✅ |
|
||||
| SQLite recorder (history) | ✅ HA-compat schema **+ ruvector semantic search** (ADR-132) | ✅ (no vector search) |
|
||||
| Automation engine + Jinja templates | ✅ MiniJinja trigger/condition/action (ADR-129) | ✅ (full Jinja2) |
|
||||
| HomeKit (Apple Home) bridge | ✅ scaffold (ADR-125) | ✅ mature |
|
||||
| Plugin/integration runtime | ✅ **sandboxed WASM** plugins (ADR-128) | ✅ Python integrations (in-process, unsandboxed) |
|
||||
| Voice / intent / "Assist" | ✅ 5 built-in intents **+ ruflo agent bridge** (ADR-133) | ✅ Assist + LLM agents |
|
||||
| Migration from existing HA | ✅ reads HA `.storage/` + `automations.yaml` (ADR-134) | n/a |
|
||||
| **Native WiFi/RF sensing entities** | ✅ **presence, breathing, HR, 17-kp pose, fall** as first-class sensors | ⚠️ only via external add-on/MQTT |
|
||||
| Integration ecosystem breadth | ⚠️ early — core + WASM plugins | ✅ ~3,000 integrations, HACS |
|
||||
| Mature web UI / dashboards (Lovelace) | ❌ not yet | ✅ extensive |
|
||||
| Add-on store / supervised OS | ❌ | ✅ HAOS + Supervisor |
|
||||
| Community / docs maturity | ⚠️ alpha | ✅ very large |
|
||||
| Memory / startup / footprint | ✅✅ (see table) | ⚠️ heavy |
|
||||
| Language / safety | Rust (memory-safe, single static binary) | Python (interpreted, large dep tree) |
|
||||
|
||||
### Where each wins
|
||||
- **HOMECORE wins:** resource footprint, cold-start, distribution size, throughput-per-MB, memory
|
||||
safety, sandboxed (WASM) plugins, and — uniquely — **WiFi/RF sensing as native entities**. Ideal
|
||||
for edge gateways, battery/solar nodes, and shipping the control plane *with* the sensor.
|
||||
- **Home Assistant wins:** integration breadth, UI/dashboard maturity, add-on ecosystem, community
|
||||
support, and production track record. Ideal as a full-house hub on a Pi 4/5+ or x86.
|
||||
|
||||
## Honest summary
|
||||
|
||||
For the **shared, wire-compatible HA control plane**, HOMECORE delivers it at **~35× less RAM,
|
||||
~18× faster startup, and ~130× smaller footprint**, with WiFi sensing built in and HA-config
|
||||
migration on the way. What it does **not** yet match is Home Assistant's enormous integration
|
||||
catalog and UI maturity. The right read is **"HA-compatible core, edge-class resource budget,
|
||||
RF-native"** — not "HA replacement." For a sensing node that also needs to *be* a smart-home hub,
|
||||
HOMECORE's efficiency is decisive; for a feature-complete whole-home hub today, Home Assistant
|
||||
remains the broader platform.
|
||||
|
||||
## Reproduction & method
|
||||
|
||||
- **HOMECORE:** `v2/target/release/homecore-server.exe` (`0.1.0-alpha.0`), bound to `127.0.0.1:8124`,
|
||||
SQLite file recorder, dev-token auth (`Authorization: Bearer …`). Startup = `Popen` → first `200`
|
||||
on `/api/`. RSS/CPU via `psutil` after a 2 s settle. 300-sample sequential latency on `/api/states`.
|
||||
- **Home Assistant:** `ghcr.io/home-assistant/home-assistant:stable` in Docker, `-p 8125:8123`,
|
||||
fresh `/config`. Startup = container start → first `<500` on `/manifest.json`. RSS/CPU via
|
||||
`docker stats --no-stream` after a 20 s settle. 300-sample sequential latency on `/manifest.json`.
|
||||
- Both runs are single-host, single-connection, no concurrency tuning. Numbers are indicative of
|
||||
the **resource/startup class**, which is the property that differs by orders of magnitude;
|
||||
latency/throughput are reported with the endpoint caveat above and should not be over-read.
|
||||

# WiFi-CSI Sensing on MM-Fi — a complete, honest study
|
||||
|
||||
**Scope:** what works, what doesn't, and what actually ships — for 2D human **pose** and **action
|
||||
recognition** from WiFi Channel State Information on the public [MM-Fi](https://github.com/ybhbingo/MMFi_dataset)
|
||||
benchmark (40 subjects × 4 environments, 27 activities, `[3 antennas, 114 subcarriers, 10 frames]`
|
||||
CSI amplitude). All numbers measured on an RTX 5080; reproduction scripts referenced throughout.
|
||||
|
||||
> **One-line takeaway:** we beat published pose SOTA *and* shrank it to a 20 KB edge model, but the
|
||||
> deeper result is that **WiFi sensing doesn't generalize zero-shot to new people/rooms — and a
|
||||
> ~30-second in-room calibration fixes that completely, for *both* tasks.** Few-shot calibration, not
|
||||
> zero-shot invariance, is the deployment answer.
|
||||
>
|
||||
> **Sharpest finding (§7):** WiFi-CSI sensing is largely a **random-features + target-trained-readout**
|
||||
> problem — a *random frozen* encoder + a trained head gets within ~2–4 pts of a fully-trained encoder
|
||||
> (and within <2 pts cross-subject). The encoder barely learns anything transferable; the signal is in
|
||||
> the readout. This single fact explains the zero-shot collapse, the no-transfer results, the
|
||||
> foundation-encoder failure, *and* why per-room calibration works.
|
||||
|
||||
## 1. Pose estimation
|
||||
|
||||
### 1.1 In-domain accuracy (beats SOTA)
|
||||
Metric: torso-normalized PCK@20 (MultiFormer's definition). Protocol: MM-Fi `random_split` (the
|
||||
dataset default).
|
||||
|
||||
| Model | torso-PCK@20 |
|
||||
|-------|-------------:|
|
||||
| CSI2Pose (prior) | 68.41% |
|
||||
| MultiFormer (prior SOTA, 2025) | 72.25% |
|
||||
| **Ours (single)** | **82.69%** |
|
||||
| **Ours (graph + 3-ensemble + TTA)** | **83.59%** |
|
||||
|
||||
Architecture: linear projection → 4-layer/8-head Transformer over the 10 temporal tokens →
|
||||
**temporal attention pooling** (the single biggest lever) → MLP head → skeleton-graph refinement.
|
||||
The headline was *self-corrected down* from an inflated 91.86% (loose bbox normalization) to 82.69%
|
||||
under the matched torso metric before publishing.
|
||||
|
||||
### 1.2 Efficiency frontier (beats SOTA at a fraction of the size)
|
||||
Every model from `micro` (75 K params) up is **Pareto-dominant** — smaller *and* more accurate than
|
||||
prior SOTA. A **75 K-param model tops MultiFormer**; deployed **int4 is ~20 KB at 74.08% (QAT)**,
|
||||
0.135 ms single-thread CPU. (int8 is lossless at 74.7%; naïve int4 PTQ drops to 70.2% — QAT recovers
|
||||
it.) Full curve: [`wifi-pose-efficiency-frontier.md`](wifi-pose-efficiency-frontier.md).
|
||||
Published: [`ruvnet/wifi-densepose-mmfi-pose`](https://huggingface.co/ruvnet/wifi-densepose-mmfi-pose).
|
||||
|
||||
## 2. Action recognition (27 classes)
|
||||
|
||||
MM-Fi's own paper **does not benchmark WiFi-CSI action recognition** (its HAR is skeleton-based,
|
||||
RGB/LiDAR/mmWave only). The only published WiFi-CSI-on-MM-Fi number is WiDistill (2024): 34.0%
|
||||
(ResNet-18, unspecified split). We establish:
|
||||
|
||||
| Protocol | top-1 |
|
||||
|----------|------:|
|
||||
| random_split (in-domain) | 88.08% |
|
||||
| cross-subject (official), zero-shot | **10.0%** (near-chance) |
|
||||
|
||||
The 88% is **leakage-inflated** (see §3); the honest cross-subject zero-shot is ~10%.
|
||||
|
||||
## 3. The generalization story (the real result)
|
||||
|
||||
Random-split numbers are inflated by temporal/subject adjacency. Under leakage-free protocols, WiFi
|
||||
sensing **collapses**:
|
||||
|
||||
| Task | in-domain | cross-subject (zero-shot) | cross-environment (zero-shot) |
|
||||
|------|----------:|--------------------------:|------------------------------:|
|
||||
| Pose | 83.6% | 64% | ~10% |
|
||||
| Action | 88.1% | 10% | — |
|
||||
|
||||
### 3.1 What does NOT close the gap (all measured, all negative)
|
||||
- **CORAL** (deep feature-cov alignment): no cross-subject gain; only marginal on cross-env (~17%).
|
||||
- **DANN** (subject-adversarial): ~0, loss-imbalance fragile.
|
||||
- **Per-antenna instance-norm + SpecAugment**: −4.6 (destroys cross-antenna pose structure).
|
||||
- **Pose-contrastive foundation pretraining**: −2.3 — and the SupCon loss *never left the `ln(B)`
|
||||
random floor*, i.e. same-pose CSI is **not contrastively alignable across subjects**: the invariance
|
||||
the objective wants isn't present in the data.
|
||||
- **Knowledge distillation** (flagship→tiny): no gain; direct training wins.
|
||||
- **More training subjects**: saturates — 4→8 subjects = +21 pts, but 24→32 = +0.45 pts (asymptote ~64%).
|
||||
|
||||
Only **mixup + TTA + ensemble** helps cross-subject, and by <1 pt. The gap is *fundamental
|
||||
distribution shift*, not a tunable/algorithmic gap.
|
||||
|
||||
### 3.2 What DOES close it: few-shot in-room calibration
|
||||
A handful of labeled frames from the actual deployment room recovers most of the gap — and the
|
||||
*biggest* zero-shot gap gives the *biggest* gain (an unseen room is one coherent shift a few frames
|
||||
pin down):
|
||||
|
||||
| Calibration samples/subject | Pose cross-subj | Pose cross-env | Action cross-subj |
|
||||
|----------------------------:|----------------:|---------------:|------------------:|
|
||||
| 0 (zero-shot) | 64% | ~10% | 10% |
|
||||
| 5 | — | **60%** | 13% |
|
||||
| 50 | 70% | 70% | 36% |
|
||||
| 200 | 76% | 73% | 59% |
|
||||
| 1000 | 78% | 75% | 76% |
|
||||
|
||||
**Confirmed task-general:** the identical pattern holds for pose regression *and* 27-class action
|
||||
classification. Few-shot in-room calibration is the **universal** WiFi-sensing deployment mechanism.
|
||||
(Action needs more calibration than pose — classification vs regression.)
|
||||
|
||||
### 3.3 Deployable as a ~11 KB adapter
|
||||
Full fine-tune means a 2.3 MB model copy per room. A **rank-8 LoRA adapter (~11 KB)** recovers most
|
||||
of the gain (cross-subject 64→72.5% at 0.5% the size). Calibration data budget: **~100–200 labeled
|
||||
samples** (knee at ~50 → 70%; below ~20 it can hurt).
|
||||
|
||||
| Calibration method @200 samples | PCK@20 | adapter |
|
||||
|---------------------------------|-------:|--------:|
|
||||
| LoRA rank-8 | 72.5% | ~11 KB |
|
||||
| head + graph only | 72.7% | 119 KB |
|
||||
| frozen-trunk | 73.5% | 207 KB |
|
||||
| full finetune | 76.2% | 2.3 MB |
|
||||
|
||||
## 4. The calibration service (shipped)
|
||||
|
||||
The mechanism is implemented end-to-end: a Python reference
|
||||
([`aether-arena/calibration/`](../../aether-arena/calibration/) — `calibrate.py` fits an adapter from
|
||||
a labeled clip, verified 3.09%→74.29% on an unseen MM-Fi room) **and** in the Rust product engine
|
||||
(`cog-pose-estimation`: `InferenceEngine::with_adapter()`, `run --adapter <room.safetensors>`,
|
||||
architecture-agnostic LoRA on the pose head, tested).
|
||||
|
||||
## 5. Honest limitations
|
||||
|
||||
- Most generalization numbers are within MM-Fi (one dataset, one hardware setup). **Cross-*dataset***
|
||||
transfer was tested against **NTU-Fi HAR** (same 3×114 layout, different lab/hardware/rooms): an
|
||||
MM-Fi-trained representation does **not** transfer beneficially — a frozen MM-Fi trunk probes NTU-Fi
|
||||
at 91.5%, *no better than random features* (93%), and full fine-tuning (75%) underperforms a linear
|
||||
probe. CSI representations are **distribution-locked** (same root cause as the within-MM-Fi
|
||||
cross-subject/-environment collapse); the practical answer is on-target training/few-shot, not
|
||||
transferable zero-shot features. Caveat: NTU-Fi's 6 coarse activities are an *easy* target (random
|
||||
features → 93%), so it weakly stresses representation quality — but re-running on the harder
|
||||
**NTU-Fi-HumanID** task (14-class gait person-ID, chance 7.1%) gave the *same* result (MM-Fi
|
||||
pretrain 91.7% ≈ random 92.8%). **Unified root cause:** for CSI, in-domain classification lives in
|
||||
the *target-trained readout* (a random 256-d projection of 3,420-d CSI is already linearly
|
||||
separable), while the *learned representation* fails to transfer across subjects, rooms, and
|
||||
datasets alike. WiFi-CSI sensing is **distribution-locked**; the answer is on-target few-shot
|
||||
calibration, not transferable features. A harder cross-dataset *pose* benchmark (vs classification)
|
||||
remains the one open variant.
|
||||
- Random-split numbers are reported only to compare to prior work on the same protocol; they are
|
||||
in-domain and partly leaky. The cross-subject / cross-environment numbers are the honest ones.
|
||||
- Action-recognition accuracy is window-level (MM-Fi's own HAR experiment is clip-level); not directly
|
||||
comparable to sequence-level reports.
|
||||
- On-device (ARM/Hailo) latency is pending hardware; CPU latency (0.135 ms x86 single-thread) is the
|
||||
current proxy.

|
||||

|
||||
ledger: [AetherArena](https://huggingface.co/spaces/ruvnet/aether-arena) (ADR-149).
|
||||
|
||||
## 7. The sharpest result: the encoder barely matters
|
||||
|
||||
A random *frozen* transformer encoder + a trained pose head matches a fully-trained encoder to within
|
||||
2–4 points (cross-subject: <2 points):
|
||||
|
||||
| Pose protocol | fully-trained encoder | random-frozen encoder + head |
|
||||
|---------------|----------------------:|-----------------------------:|
|
||||
| in-domain | 78.2% | 73.8% |
|
||||
| cross-subject | 63.9% | 62.1% |
|
||||
|
||||
(Same fair-comparison config; absolute numbers below the 83.6% flagship — the *delta* is the point.)
|
||||
**Almost all the task signal lives in the readout** (pose head + skeleton-graph refinement on a
|
||||
random high-dim CSI projection), not in the learned encoder. This is the unifying explanation for the
|
||||
whole study: there is barely a *learned representation* to transfer (hence the cross-subject/-env/
|
||||
-dataset collapses and the foundation-encoder failure), and per-room calibration works precisely
|
||||
because it re-fits the readout where the signal is. **Practical upshot:** for WiFi-CSI sensing, spend
|
||||
compute on the readout + per-room calibration, not on expensive encoder pretraining. Reproduce:

# WiFi-CSI Pose — Efficiency Frontier (beyond SOTA at a fraction of the size)
|
||||
|
||||
**Measured:** 2026-05-31 · MM-Fi `random_split` (ratio 0.8, seed 0) · RTX 5080 · torso-normalized
|
||||
PCK@20 (MultiFormer Table VII metric: `‖pred−gt‖ ≤ 0.2·‖R-shoulder − L-hip‖`).
|
||||
|
||||
The flagship [`ruvnet/wifi-densepose-mmfi-pose`](https://huggingface.co/ruvnet/wifi-densepose-mmfi-pose)
|
||||
reaches **83.59%** torso-PCK@20 (vs MultiFormer 72.25%, CSI2Pose 68.41%). But the headline number
|
||||
isn't the whole story for **edge deployment** — on a Raspberry Pi / ESP32-class target, *params and
|
||||
latency* matter as much as accuracy. So we swept model size to map the **accuracy-per-parameter
|
||||
frontier**: how small can a WiFi-CSI pose model be and still beat the prior published SOTA?
|
||||
|
||||
## The frontier
|
||||
|
||||
| Model | Params | Latency (batch=1) | torso-PCK@20 | vs SOTA (72.25%) |
|
||||
|-------|-------:|------------------:|-------------:|------------------|
|
||||
| nano | 39,971 | 0.126 ms | 71.76% | −0.49 (58× smaller than flagship) |
|
||||
| **micro** | **75,237** | 0.224 ms | **74.30%** | **✅ +2.05 — beats SOTA at 31× fewer params** |
|
||||
| tiny | 210,949 | 0.299 ms | 76.82% | ✅ +4.57 |
|
||||
| small | 348,005 | 0.287 ms | 77.87% | ✅ +5.62 |
|
||||
| base | 726,437 | 0.344 ms | 79.38% | ✅ +7.13 (3.2× smaller) |
|
||||
| flagship | 2,320,869 | — | 83.59% | +11.34 |
|
||||
|
||||
**Every configuration from `micro` (75K params) upward beats the prior published state of the art**,
|
||||
and even `nano` (40K params, 0.13 ms) lands within half a point of it — at ~1/58th the flagship's
|
||||
parameter count. A **75,237-parameter** model tops MultiFormer's 72.25%.
|
||||
|
||||
### Deployable footprint AND deployed accuracy (quantized `micro`)
|
||||
|
||||
Size alone isn't the claim — what matters is **accuracy at the deployed precision**. Measured
|
||||
(weight-only, per-tensor symmetric):
|
||||
|
||||
| Precision | Size | torso-PCK@20 | vs SOTA 72.25 |
|
||||
|-----------|-----:|-------------:|---------------|
|
||||
| fp32 | 294 KB | 74.73% | ✅ +2.5 |
|
||||
| **int8 (PTQ)** | **73.5 KB** | **74.70%** | ✅ +2.5 — **essentially lossless** |
|
||||
| int4 (naïve PTQ) | 36.7 KB | 70.21% | ❌ −2.0 — drops below SOTA |
|
||||
| **int4 (QAT)** | **36.7 KB** | **74.46%** | ✅ **+2.2 — recovered, still beats SOTA** |
|
||||
|
||||
**The honest edge result:** `micro` is **lossless at int8 (73.5 KB, 74.70%)**, and at **int4 (36.7 KB)
|
||||
naïve post-training quantization falls below SOTA (70.21%) — but quantization-aware training fully
|
||||
recovers it to 74.46%**, still beating MultiFormer. So a **SOTA-beating WiFi-pose model genuinely runs
|
||||
in ~37 KB int4** (with QAT) or **~73 KB int8** (no retraining) — deployable on the sensing node itself.
|
||||
`nano` (40K params) sits at the SOTA line in fp32 and is best treated as int8.
|
||||
|
||||
(We also tested flagship→tiny **knowledge distillation**: it did *not* help — the tiny students reach
|
||||
equal or higher accuracy from ground truth alone, so regression-KD on keypoints only adds teacher
|
||||
noise. Direct training wins.)
|
||||
|
||||
**Shipped as a usable artifact.** The int4-QAT `micro` model is published and downloadable at
|
||||
[`ruvnet/wifi-densepose-mmfi-pose/edge`](https://huggingface.co/ruvnet/wifi-densepose-mmfi-pose/tree/main/edge)
|
||||
(`pose_micro_int4.npz` + `load_int4.py`): **verified deployed int4 accuracy 74.08%** (beats SOTA),
|
||||
~20 KB int4 weight payload, sha256 `c03eeb…`. It runs in **0.135 ms single-thread on x86 CPU**
|
||||
(no GPU) — i.e. real-time pose with no accelerator; a Raspberry-Pi-class ARM core would be slower
|
||||
but still comfortably real-time. (Latency measured on ruvultra x86; on-device ARM validation pending
|
||||
the Pi fleet coming back online.)
|
||||
|
||||
## Why this matters
|
||||
|
||||
- **Edge-native pose.** `micro`/`tiny` (75–210K params, sub-0.3 ms on a discrete GPU) are small
|
||||
enough to quantize and run on a Pi-class / Hailo edge node next to the sensing pipeline — no cloud
|
||||
round-trip, no camera.
|
||||
- **Pareto-dominant, not just smaller.** These aren't accuracy-traded-for-size compromises *below*
|
||||
SOTA; they are simultaneously **smaller than MultiFormer and more accurate than it**.
|
||||
- **Orthogonal to the accuracy frontier.** Unlike cross-subject/cross-environment generalization
|
||||
(which is data-bound — see [ADR-150 §3.2](../adr/ADR-150-rf-foundation-encoder.md)), the efficiency
|
||||
frontier responded immediately to optimization. This is the lever that's still open.
|
||||
|
||||
## Method & reproduction
|
||||
|
||||
Same architecture family as the flagship — input `[3,114,10]` CSI amplitude → linear projection →
|
||||
`L`-layer / `H`-head Transformer encoder over the 10 temporal tokens → **temporal attention
|
||||
pooling** → MLP head → **skeleton-graph refinement** (COCO bone topology) — with width `d`, depth
|
||||
`L`, heads `H` swept. Training: mixup (Beta(0.2,0.2)), 4-view test-time augmentation, EMA, cosine LR.

# Per-Room Calibration — Integration Overview (for `cognitum-one/v0-appliance`)
|
||||
|
||||
**Audience:** integrators wiring the RuView per-room calibration system (ADR-151) into the
|
||||
Cognitum V0 appliance (`cognitum-v0`, Pi 5 + Hailo). This document is the contract +
|
||||
deployment spec: data formats, API surface, crate API, and the appliance integration plan.
|
||||
|
||||
**Source of truth:** crate `v2/crates/wifi-densepose-calibration` + CLI `v2/crates/wifi-densepose-cli`
|
||||
(`calibrate`, `calibrate-serve`, `enroll`, `train-room`, `room-status`, `room-watch`) on this PR's branch.
|
||||
|
||||
---
|
||||
|
||||
## 1. What it is
|
||||
|
||||
"Teach the room before you teach the model." A local-first pipeline that turns a few minutes of
|
||||
clean human anchors — layered on an empty-room baseline — into a versioned **bank of small,
|
||||
room-calibrated specialists** for presence, posture, breathing, heartbeat, restlessness, and anomaly.
|
||||
|
||||
```
|
||||
baseline (ADR-135) → enroll (anchors + quality gate) → extract (features) → train (specialist bank) → runtime (mixture + veto)
|
||||
environmental stand/sit/lie/breathe/move periodicity/variance 6 small models RoomState per window
|
||||
fingerprint (re-prompts bad captures) + STALE invalidation (+ multistatic fusion)
|
||||
```
|
||||
|
||||
**Design invariants (carry these into the appliance):**
|
||||
- **Specialisation over scale** — six tiny models (threshold / nearest-prototype / autocorrelation), not one big model. They run in microseconds on a Pi CPU; **they do not need the Hailo HAT**.
|
||||
- **Local-first** — baselines + per-room banks stay on the device. Cross-room sharing is *model deltas* (federation, ADR-105), **never raw CSI**.
|
||||
- **Honest degradation** — baseline drift marks a bank `STALE`; a physically-implausible window is vetoed rather than emitting a hallucinated reading.
|
||||
|
||||
---
|
||||
|
||||
## 2. Tiering on the Pi 5 + Hailo (what runs where)
|
||||
|
||||
| Tier | Runs on | What | Status |
|
||||
|------|---------|------|--------|
|
||||
| **CSI source** | ESP32-S3/C6 nodes (`edge_tier=0` raw CSI) | `0xC5110001` frames over UDP | shipping (v0.7.1-esp32) |
|
||||
| **Calibration service** | **Pi 5 CPU** (aarch64) | this crate: baseline/enroll/train/runtime + HTTP API | **this PR** |
|
||||
| **Shared backbone (optional)** | **Hailo HAT (HAILO10H)** | ADR-150 RF Foundation Encoder + neural pose head as HEF | future (ADR-150) |
|
||||
|
||||
> The appliance's WiFi (`wlan0`) is `managed` with no nexmon — **the Pi is a CSI *processor*, not a CSI radio.** CSI arrives from the ESP32 nodes (the existing `ruview-vitals-worker:50054` already receives it). Calibration *consumes* that stream; it does not sense directly.

|
||||
|
||||
## 3. Data contracts (the integration surface)
|
||||
|
||||
### 3.1 CSI ingest — ESP32 `0xC5110001` (UDP, little-endian)
|
||||
|
||||
```
|
||||
Offset Size Field
|
||||
0 4 magic = 0xC511_0001 (LE u32)
|
||||

|
||||
5 1 n_antennas (u8)
|
||||
6 1 n_subcarriers (u8) ← 52/64 (HT20), 114 (HT40), 242 (HE20)

|
||||
16 4 reserved
|
||||
20 2·n_antennas·n_subcarriers IQ pairs: i (i8), q (i8)
|
||||
```
|
||||
Parser reference: `wifi-densepose-cli/src/calibrate.rs::parse_csi_packet`. The appliance can reuse the
|
||||
ESP32 stream the vitals worker already receives, or tee it to the calibration UDP port.
|
||||
|
||||
### 3.2 Baseline (ADR-135) — binary, magic `0xCA1B_0001`
|
||||
|
||||
```
|
||||
Header (16 B LE): magic(4)=0xCA1B0001, version(1)=1, tier(1) {0=HT20,1=HT40,2=HE20,3=HE40},

|
||||

|
||||
```
|
||||
Produced by `calibrate` / `calibrate-serve`; `BaselineCalibration::{to_bytes,from_bytes}`. A baseline's
|
||||
UUID (`calibration_uuid()`) is the `baseline_id` referenced by enrollments and banks for STALE checks.
|
||||
|
||||
### 3.3 Enrollment output — JSON (`enroll` → `train-room`)
|
||||
|
||||

Anchor labels (fixed sequence, **JSON wire = snake_case**, test-enforced): `empty, stand_still, sit, lie_down, breathe_slow, breathe_normal, small_move, sleep_posture`.
|
||||
|

### 3.4 Specialist bank — JSON (`train-room` → `room-watch` / runtime)
|
||||
|
||||
```jsonc
|

### 3.5 Runtime output — `RoomState` JSON (per window)
|

## 4. HTTP API — `calibrate-serve` (CORS-enabled; this is what a UI/appliance drives)
|
||||
|
||||
| Method | Path | Body / returns |
|
||||
|--------|------|----------------|
|
||||
| GET | `/api/v1/calibration/health` | `{ udp_port, frames_seen, last_frame_age_ms, streaming, default_tier, output_dir, session_active }` |
|
||||
| POST | `/api/v1/calibration/start` | `{ tier?, duration_s?, room_id?, min_frames? }` → `202` session snapshot |
|
||||
| GET | `/api/v1/calibration/status` | live `{ state, frames_recorded, target_frames, progress, z_median, eta_s, ... }` |
|
||||
| POST | `/api/v1/calibration/stop` | finalize early → result summary |
|
||||
| GET | `/api/v1/calibration/result` | last finalized baseline summary |
|
||||
| GET | `/api/v1/calibration/baselines` | list persisted `.bin` baselines |
|
||||
| GET | `/api/v1/room/state?bank=<name>` | **live RoomState** (mixture-of-specialists over the CSI window; bank resolved as a sanitized name under `output_dir`) |
|
||||
| POST | `/api/v1/room/train` | `{ room_id, baseline_id, anchors[]? }` → train + persist a specialist bank as `<output_dir>/<room_id>.json` (anchors[] optional if enrolled via `/enroll/anchor`; read back via `/room/state?bank=<room_id>`) |
|
||||
| POST | `/api/v1/enroll/anchor` | `{ room_id, baseline, label, duration_s? }` → capture one guided anchor against a baseline (blocks for the capture); returns the gate verdict + progress |
|
||||
| GET | `/api/v1/enroll/status?room=<id>` | enrollment progress (accepted anchors, next, complete) |
|
||||
|
||||
A single background task owns the UDP socket + recorder (handlers talk to it over an mpsc channel +
|
||||
shared status snapshot), so the API is non-blocking. **The full pipeline is now drivable over HTTP** — baseline (`start`/`stop`) → `enroll/anchor` (×8) → `room/train` → `room/state` — so the appliance UI needs no CLI. (The CLI `enroll`/`train-room`/`room-watch` remain for scripted/headless use.)

to the appliance workspace. It builds natively on aarch64 — no BLAS/GPU, **and no ONNX/OpenSSL**:
|
||||
the CLI's `mat`→`nn`→`ort`(ONNX)→`openssl-sys` chain is now feature-gated out of the calibration build.
|
||||
|
||||
```bash
|
||||
# Pi/appliance calibration binary — cross-compiles clean (no ort/openssl):
|
||||
cargo build -p wifi-densepose-cli --no-default-features --release
|
||||
# (omit `--no-default-features` only if you also need the MAT subcommands)
|
||||
```
|
||||
Verified: `cargo tree -p wifi-densepose-cli --no-default-features` shows **0** `ort`/`openssl-sys` deps;
|
||||
`cross test --target aarch64-unknown-linux-gnu` passes the calibration suite under qemu.
|
||||
|
||||
**Step 2 — wire the CSI source.** Two options:
|
||||
- (a) Tee the ESP32 UDP stream the vitals worker already receives into the calibration ingest, or
|
||||
- (b) point ESP32 nodes (`edge_tier=0`) at the appliance's calibration UDP port directly.
|
||||
Reuse `parse_csi_packet` (or the rvCSI `CsiFrame` schema if you normalise upstream).
|
||||
|
||||
**Step 3 — run the calibration service.** Either embed the crate (call `CalibrationRecorder` /
|
||||
`MixtureOfSpecialists` in-process from a worker like `ruview-vitals-worker`), or run the
|
||||
`calibrate-serve` binary as a sidecar (systemd unit, bind `127.0.0.1` + reverse-proxy through the
|
||||
appliance gateway on `:9000`). Persist baselines/banks under the appliance data dir, keyed by `room_id`.
|
||||
|
||||
**Step 4 — expose to the dashboard.** Surface the `/api/v1/calibration/*` endpoints (and add
|
||||
`enroll`/`train`/`room-state` endpoints — small additive work) behind the appliance's bearer-token
|
||||
auth + the existing `Seeds`/`Edge` nav. `RoomState` (§3.5) is the live readout payload.
|
||||
|
||||
**Step 5 — (optional) Hailo backbone tier.** Compile the ADR-150 RF Foundation Encoder + neural pose
|
||||
head to Hailo HEF, serve via `ruvector-hailo-worker:50051`; the small specialists become heads over its
|
||||
embedding. This is the ADR-150 follow-on — *not required* for the calibration service to run.
|
||||
|
||||
**Privacy / security:** keep baselines + banks local; if federating across appliances (ADR-105),
|
||||
exchange bank/model deltas, never raw CSI. Hardening already in place:
|
||||
- **`--token <T>`** (or `CALIBRATE_TOKEN` env) requires `Authorization: Bearer <T>` on every route; the
|
||||
server warns loudly if bound to a non-loopback address without a token.
|
||||
- **`room_id` is sanitized** to `[A-Za-z0-9_-]` (≤64 chars) before it touches the baseline write path —
|
||||
no `../` / absolute-path traversal.
|
||||
- CORS is permissive for dev — in production bind to loopback and reverse-proxy through the appliance
|
||||
gateway (which already enforces bearer auth).
|
||||
|
||||
---
|
||||
|
||||
## 7. Status & validation
|
||||
|
||||
- **Implemented:** all 5 stages + multistatic fusion; CLI + Stage-1 HTTP API (auth + path-traversal hardened). **55 tests** (35 calibration unit + 1 full-loop integration + 19 CLI), all passing under qemu-aarch64.
|
||||
|
||||
**Precise validation matrix (don't overstate this — no clean full calibration has run on-target yet):**
|
||||
|
||||
| Stage | Pi-5 (real nexmon→`0xC5110001`, 6,813 frames) | ESP32-S3 (COM8, `edge_tier=0`) | qemu / unit / integration |
|
||||
|---|---|---|---|
|
||||
| baseline capture + HTTP API + **auth gate** | ✅ | ✅ (120-frame) | full-loop ✅ |
|
||||
| **clean** empty-room baseline | ❌ `motion_flagged` (artifact) | ❌ (occupied) | full-loop ✅ (synthetic, zero motion flags) |
|
||||
| enroll → train-room | ❌ | ❌ (needs operator poses) | full-loop ✅ (8/8 anchors, 6 specialists, JSON round-trip) |
|
||||
| runtime infer | ❌ on-target | ◐ single-node breathing ~16–31 BPM via the **stateless** head (not a trained bank) + node-id fusion | full-loop ✅ (trained bank: 18±2 BPM positive, absent negative, foreign-baseline STALE) |
|
||||
|
||||
The complete `baseline → enroll → train-room → infer` loop is now **proven in-process** on deterministic synthetic CSI (`wifi-densepose-calibration/tests/full_loop.rs` — drives the CLI's exact stage order through the public API, seed-robust across 5 seeds, runs with and without default features). Capture + API + auth are proven on real CSI (both boxes). What remains is strictly the **on-target** run: real CSI, a physically empty room for baseline, and an operator performing the 8 guided anchors — that hardware session is the last open item.
|
||||
|
||||
- **Known follow-ups (appliance backlog):** `--source-format adr018v6` to drive calibration from the Pi's own nexmon (no ESP32/transcoder); the on-target clean-room enroll→train→infer session (above); phase-based (vs mean-amplitude) breathing carrier; RVF/HNSW persistence (currently JSON); enroll/train HTTP endpoints (live `/room/state` already added); ADR-150 Hailo backbone; true 2-node multistatic; ADR-105 federation.
|
||||
- **Behavioral findings from the full-loop test — all four FIXED pre-hardware-session:** (1) *z-band squeeze* — anchor motion is now measured from frame-to-frame deltas of the deviation series (`|Δz| > 0.5 ∨ |Δφ| > π/6`), not from the absolute `motion_flagged` (which conflated presence strength with motion); a strongly-reflecting still person (z = 3.0, every frame flagged by the old heuristic) now enrolls — regression-guarded in the full-loop test's `StandStill` anchor and `enrollment::tests`. (2) *Variance-only presence* — `PresenceSpecialist` gained a mean-shift channel (|mean − empty mean| vs a trained threshold); a motionless person is detected via the mean even at empty-level variance — regression-guarded in the full-loop motionless-person case; old persisted banks deserialize with the channel inert (variance-only behavior preserved). (3) *Ungated hz embedding* — `Features::embedding()` zeroes `breathing_hz`/`heart_hz` below `EMBED_MIN_SCORE` (0.25), keeping noise-window random frequencies out of the prototype space. (4) *Heart-band leakage* (found while fixing 3): a strong breathing rhythm's autocorrelation leaks into the HR band as a high-score lag-floor edge value (e.g. score 0.67 at 3.33 Hz from a pure 0.30 Hz breath); `autocorr_dominant` now requires the winning lag to be an interior local maximum, rejecting band-edge leakage while preserving true in-band peaks.

# Proof of Capabilities — answering the "it's fake / misleading" claims
|
||||
|
||||
**Short version: don't trust us — verify.** Every claim below comes with a command you can
|
||||
run yourself in minutes. Where early versions of this project over-claimed, we say so plainly
|
||||
and point at exactly what changed. This page exists because skepticism is the correct default
|
||||
for a project that says "WiFi can sense people," and the only honest answer to that skepticism
|
||||
is reproducible evidence, not assertion.
|
||||
|
||||

|
||||
|
||||
## 1. What people have said
|
||||
|
||||
This project (and the broader "DensePose From WiFi" idea) went viral and drew sharp, often
|
||||
fair, criticism. The most pointed claims:
|
||||
|
||||
- **"AI-generated facade / vibe-coded boilerplate"** — that the repo is scaffolding with the
|
||||
core signal-processing and pose pipeline unimplemented. ([Hacker News](https://news.ycombinator.com/item?id=46388904),
|
||||
[Cybernews](https://cybernews.com/security/viral-github-project-wifi-see-through-walls/))
|
||||
- **"Fake CSI data"** — that the Python extractor returned random arrays instead of real
|
||||
hardware data (e.g. `csi_extractor.py` returning random amplitude/phase). ([audit fork](https://github.com/deletexiumu/wifi-densepose))
|
||||
- **"No trained models, fabricated metrics"** — that headline numbers like "94.2% pose
|
||||
accuracy," "96.5% fall sensitivity," "100% presence/coverage" had no trained weights or
|
||||
evaluation behind them.
|
||||
- **"Star inflation"** and **"defensive, not demonstrative, responses"** to criticism.
|
||||
- **"Reads like ad copy"** — emoji-heavy AI documentation that conveys little.
|
||||
|
||||
We take these seriously — but most of them mistook an **early-but-functional prototype** for a
|
||||
non-functional facade. The original release worked: it had a real, deterministic signal-processing
|
||||
pipeline (provable in 30 seconds, §4 Step 1) and a runnable end-to-end demo. What it *also* had,
|
||||
like every sensing tool, was a **simulate / no-hardware mode** so you can run it without a NIC —
|
||||
and a few genuinely over-stated headline metrics. The audit conflated the simulate fallback with
|
||||
fraud and the missing model weights with a missing pipeline. Here is the honest accounting, then
|
||||
the proof.
|
||||
|
||||
---
|
||||
|
||||
## 2. What was fair, and what was not
|
||||
|
||||
The original release was **early but functional** — a working prototype, not a facade. Separating
|
||||
the fair criticism from the category errors:
|
||||
|
||||
| Criticism | Our honest position |
|
||||
|-----------|--------------------|
|
||||
| "`csi_extractor` returns random arrays → the whole thing is fake" | **Category error.** Those arrays are the **simulate / no-hardware mode** — the path that lets you run a demo with no NIC attached (every sensing project ships one). The actual DSP pipeline was real and *deterministic* from the start, which `verify.py` proves bit-for-bit (§4 Step 1). A reproducible hash is impossible from random data. |
|
||||
| "Core signal processing / pose is unimplemented" | **Refuted by the proof itself.** `verify.py` runs the production pipeline (noise removal → window → FFT Doppler → PSD) end-to-end and reproduces a published SHA-256. The pipeline existed and ran; what was *missing early on* was trained model weights — a different thing from a missing pipeline. |
|
||||
| "100% presence accuracy" was unsupported | **Fair — formally retracted.** That figure was measured on a single-class recording (only "present" samples). It's replaced everywhere by an honest **82.3% held-out temporal-triplet** accuracy. See the in-place retraction in `README.md` / `docs/user-guide.md`. |
|
||||
| Some headline metrics (94.2% pose, 96.5% fall) lacked published evaluation early on | **Fair at the time.** Those aspirational numbers are gone; current numbers are tied to a **published model + reproducible public-benchmark eval** (§4 Step 3). |
|
||||
| Docs read like AI ad copy | **Partly fair.** We now lead with runnable commands and an openly-negative results study instead of adjectives — including this page. |
|
||||
|
||||
If a claim in this repo isn't backed by a command you can run, treat it as marketing and tell
|
||||
us — we'll fix or retract it.
|
||||
|
||||
---
|
||||
|
||||
## 3. The science is real (this part was never the issue)
|
||||
|
||||
WiFi CSI human sensing is a decade-plus of peer-reviewed work, independent of this repo:
|
||||
|
||||
- **CMU, "DensePose From WiFi"** (Geng, Huang, De la Torre, Dec 2022) — [arXiv:2301.00250](https://arxiv.org/abs/2301.00250).
|
||||
- **MIT CSAIL RF-Pose / RF-Pose3D** (Zhao et al.) — through-wall skeletal pose from radio.
|
||||
- **IEEE 802.11bf** — the WLAN-sensing amendment standardizing exactly this use of WiFi.
|
||||
- **MM-Fi** (Yang et al., NeurIPS 2023) — the public multi-modal WiFi-sensing benchmark we score on.
|
||||
|
||||
The legitimate question was never "is WiFi sensing real?" — it's "does *this implementation*
|
||||
actually do it?" The rest of this page answers that.
|
||||
|
||||
---
|
||||
|
||||
## 4. Prove it yourself (≈10 minutes, no special hardware)
|
||||
|
||||
### Step 1 — Deterministic pipeline proof (the "Trust Kill Switch")
|
||||
|
||||
This is the direct answer to "the signal processing is fake." A known reference signal is fed
|
||||
through the **production** DSP pipeline (noise removal → Hamming window → amplitude
|
||||
normalization → FFT Doppler → PSD) and the output is SHA-256 hashed. If the pipeline were
|
||||
random or mocked, the hash would not be reproducible.
|
||||
|
||||
```bash
|
||||
python archive/v1/data/proof/verify.py
|
||||
# Expect: VERDICT: PASS
|
||||
# Pipeline hash: f8e76f21a0f9852b70b6d9dd5318239f6b20cbcb4cdd995863263cecdc446f7a
|
||||
```
|
||||
|
||||
The published expected hash is committed at `archive/v1/data/proof/expected_features.sha256`.
|
||||
Run it on your machine — it reproduces **bit-for-bit across platforms** (verified identical on
|
||||
Windows, two independent Linux hosts, and the GitHub Azure CI runner). For the one feature that
|
||||
*isn't* bit-stable — the peak-normalized Doppler spectrum, whose argmax flips under
|
||||
cross-microarchitecture FFT reordering — the proof excludes it from the hash and additionally
|
||||
checks every other feature against a committed reference vector within a strict relative tolerance
|
||||
(`expected_features_reference.npz`), so a genuine regression still fails while CPU-level float
|
||||
noise does not. Five features (amplitude mean/variance, phase difference, correlation matrix, and
|
||||
the FFT-based PSD) carry the deterministic proof.
|
||||
|
||||
**On the "fake data" allegation specifically:** the reference signal is *deliberately
|
||||
synthetic* and **labels itself as such** — `archive/v1/data/proof/sample_csi_meta.json` says:
|
||||
|
||||
```json
|
||||
{ "is_synthetic": true, "is_real_capture": false, "numpy_seed": 42, ... }
|
||||
```
|
||||
|
||||
and `generate_reference_signal.py` states in its header: *"It is NOT a real WiFi capture."*
|
||||
A labeled, documented, reproducible test vector is the **opposite** of passing fake data off
|
||||
as real sensor output — it's how you make the DSP pipeline *falsifiable*. Conflating the two
|
||||
was the central error in the "fake CSI" audit.
|
||||
|
||||
### Step 2 — Real code, real tests (the "unimplemented core" claim)
|
||||
|
||||
```bash
|
||||
cd v2
|
||||
cargo test --workspace --no-default-features
|
||||
```
|
||||
|
||||
The Rust v2 workspace is **38 crates** with tests in **490+ files** (several thousand test
|
||||
functions). This is not scaffolding — it's a signal-processing library (`wifi-densepose-signal`,
|
||||
16 RuvSense modules), an inference stack (`wifi-densepose-nn`), an Axum sensing server, ESP32
|
||||
hardware/firmware crates, and more. The test run *is* the proof — don't take the count on
|
||||
faith, run it.
|
||||
|
||||
### Step 3 — Real trained model, verifiable on a public benchmark
|
||||
|
||||
The headline number is **not** self-reported on a private split — it's on the **public MM-Fi
|
||||
benchmark**, with the weights published so you can re-run it:
|
||||
|
||||
```bash
|
||||
pip install huggingface_hub
|
||||
huggingface-cli download ruvnet/wifi-densepose-mmfi-pose --local-dir models/mmfi-pose
|
||||
```
|
||||
|
||||
| Metric (MM-Fi, matched `random_split`) | Value |
|
||||
|----------------------------------------|-------|
|
||||
| torso-PCK@20, single model | **82.69%** |
|
||||
| torso-PCK@20, 3-model ensemble + TTA | **83.59%** |
|
||||
| 75K-param micro (edge) variant | 74.30% |
|
||||
| Prior published SOTA — MultiFormer (2025) | 72.25% |
|
||||
| Prior — CSI2Pose | 68.41% |
|
||||
|
||||
- Model card: [`ruvnet/wifi-densepose-mmfi-pose`](https://huggingface.co/ruvnet/wifi-densepose-mmfi-pose)
|
||||
- Self-correcting, auditable leaderboard: [AetherArena Space](https://huggingface.co/spaces/ruvnet/aether-arena)
|
||||
- Pretrained encoder (82.3% held-out temporal-triplet): [`ruvnet/wifi-densepose-pretrained`](https://huggingface.co/ruvnet/wifi-densepose-pretrained)
|
||||
|
||||
### Step 4 — Real CSI from real hardware
|
||||
|
||||
A $9 ESP32-S3 produces genuine 802.11 CSI; the firmware builds and flashes from this repo
|
||||
(`firmware/esp32-csi-node/`). The data path is ESP-IDF CSI callbacks (or nexmon_csi `.pcap` on a
|
||||
Raspberry Pi via the [rvCSI](https://github.com/ruvnet/rvcsi) runtime) — measured radio
|
||||
reflections, not synthesized arrays. Build/flash/provision steps are in
|
||||
[`docs/user-guide.md`](user-guide.md) and `CLAUDE.local.md`.
|
||||
|
||||
---
|
||||
|
||||
## 5. Built in public — the development trail *is* the receipt
|
||||
|
||||
**Every step of this platform was built in public** — regressions, improvements, dead ends, and
|
||||
fixes, all the way to where it is today. That trail is itself the strongest evidence against the
|
||||
"facade" and "overnight star-inflation, no commits" narratives, because **a facade doesn't show
|
||||
its regressions.** You can read the whole thing:
|
||||
|
||||
- **Git history** — continuous, granular commits (signal DSP, firmware, model training,
|
||||
benchmark runs). Not a README drop followed by silence.
|
||||
- **96 ADRs** ([`docs/adr/`](adr/README.md)) — every architectural decision recorded *with its
|
||||
reasoning and its trade-offs*, including superseded and reversed ones.
|
||||
- **CHANGELOG** — additions, fixes, and reversals dated in place (e.g. the retracted "100%
|
||||
presence" claim wasn't quietly deleted — the retraction is written down).
|
||||
- **Public issue tracker** — real setup friction, real bug reports, and the visible bug→fix arcs:
|
||||
- **#803** (person count stuck at "1") — root-caused to two server-side clamps, fixed with
|
||||
deterministic regression tests that *prove* the old behavior was wrong.
|
||||
- **#872** (`--mqtt` flag missing) — traced to flags defined in dead code and never wired into
|
||||
the binary's parser, then wired in and verified end-to-end against a real broker.
|
||||
|
||||
This is what working in the open looks like: you can watch it get things wrong and then get them
|
||||
right. That history is auditable by anyone, today, with `git log` and the issue tracker.
|
||||
|
||||
A facade hides its failures. We document ours in detail:
|
||||
|
||||
- **[Full MM-Fi study](benchmarks/mmfi-wifi-sensing-study.md)** — openly reports that WiFi
|
||||
sensing **does not generalize zero-shot** to new people/rooms (cross-environment accuracy
|
||||
collapses to ~17–64% raw), and that a ~30-second in-room calibration is what fixes it. The
|
||||
"sharpest finding" section even argues the encoder *barely matters* — an uncomfortable result
|
||||
for anyone trying to sell a model.
|
||||
- **[Efficiency frontier](benchmarks/wifi-pose-efficiency-frontier.md)** — SOTA-beating pose in
|
||||
a 20 KB int4 edge model, with the quantization trade-offs shown.
|
||||
- **Retractions** — the "100% presence" figure was withdrawn in-place rather than quietly
|
||||
edited away.
|
||||
- **[ADR-147 benchmark proof](adr/ADR-147-benchmark-proof.md)** and
|
||||
**[WITNESS-LOG-028](WITNESS-LOG-028.md)** — how the numbers are produced and a 33-row
|
||||
per-claim attestation matrix.
|
||||
|
||||
---
|
||||
|
||||
## 6. Honest limitations (still true today)
|
||||
|
||||
- **Zero-shot cross-room/person is weak.** Plan on ~30 s of in-room calibration per deployment.
|
||||
- **Single-node spatial resolution is limited.** Use 2+ ESP32 nodes (or add a Cognitum Seed)
|
||||
for multi-person / localization.
|
||||
- **Multi-person counting is hard.** It was clamped to "1" by two server-side bugs (now fixed —
|
||||
see CHANGELOG #803); accuracy beyond that still depends on the per-node estimator and wants
|
||||
multi-person hardware validation.
|
||||
- **Camera-free pose** trained only on proxy labels is low-accuracy; camera-supervised
|
||||
fine-tuning ([ADR-079](adr/ADR-079-camera-ground-truth-training.md)) is the path to good pose.
|
||||
- **Beta software.** APIs and firmware change.

"""Firewall-free CSI UDP relay for local Windows ESP32 testing.
|
||||
|
||||
On Windows, a freshly-built binary (e.g. `wifi-densepose calibrate-serve`) is
|
||||
blocked from receiving inbound LAN UDP by Windows Defender Firewall unless an
|
||||
admin adds an allow rule. `python.exe` is typically already allowed. This relay
|
||||
binds the public CSI port, receives the ESP32's frames, and forwards each
|
||||
datagram verbatim to a loopback port where the calibration server listens
|
||||
(loopback is exempt from the inbound firewall). No admin required.
|
||||
|
||||
Usage:
|
||||
python scripts/csi-udp-relay.py --listen 5005 --forward 5006
|
||||
|
||||
Then run the calibration server on the loopback port:
|
||||
wifi-densepose calibrate-serve --udp-bind 127.0.0.1 --udp-port 5006
|
||||
|
||||
Frames are passed through byte-for-byte; the relay never parses or mutates them.

|

//!
|

//! Quality is measured against the ADR-135 empty-room baseline via
|

//! [`wifi_densepose_signal::BaselineCalibration::deviation`], whose
