+
+          ## Modes
+
+          - Default — synthetic in-browser demo (no backend, no network calls).
+          - `?backend=auto` — fetch from `/api/splats` on the same origin
+            (only works when the viewer is served by `ruview-pointcloud serve`).
+          - `?backend=<url>` — fetch from `<url>/api/splats`. The intended
+            local-ESP32 use is `?backend=http://127.0.0.1:9880`: run
+            `ruview-pointcloud serve --bind 127.0.0.1:9880` on the same
+            machine with your ESP32 streaming CSI to UDP port 3333, then
+            visit the URL above. The local server's CorsLayer permits
+            requests from `https://ruvnet.github.io`, and modern browsers
+            permit HTTPS→127.0.0.1 mixed-content as a trustworthy origin.
+            The "📡 Connect ESP32" button in the viewer prompts for this
+            URL and persists it in localStorage.
+          - `?live=1` — require a live backend; show an offline message instead
+            of falling back to the synthetic demo.
+
+          See ADR-094 for the deployment design.

 ## [Unreleased]
 
+### 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.
+- **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. Applied at:
+  - `POST /api/v1/recording/start` (`recording.rs` — `session_name`)
+  - `GET /api/v1/recording/download/:id` (`recording.rs` — `id`)
+  - `DELETE /api/v1/recording/delete/:id` (`recording.rs` — `id`)
+  - `POST /api/v1/models/load` (`model_manager.rs` — `model_id`)
+  - `training_api.rs` `load_recording_frames` (`dataset_id`s)
+
+  Pre-fix, unauthenticated callers could read `../../etc/passwd`-style paths, write arbitrary JSONL files, load attacker-controlled `.rvf` model files, or delete arbitrary files the server process could touch. 9 unit tests in `path_safety::tests` exercise the rejection envelope (empty, too-long, path separators, parent-dir traversal, null byte, whitespace/specials, non-ASCII).
+
 ### Fixed
+- **WebSocket `/ws/sensing` now reports `esp32:offline` when ESP32 hardware goes stale** (closes #618). `broadcast_tick_task` was re-emitting the cached `latest_update` with a frozen `source: "esp32"` field forever after the hardware lost power or network. The REST `/health` endpoint already called `effective_source()` (which returns `"esp32:offline"` after `ESP32_OFFLINE_TIMEOUT` = 5 s with no UDP frames), but the WS broadcast path was the one consumer that didn't. Result: the UI's "LIVE — ESP32 HARDWARE Connected" banner stayed green long after the hardware went away, and `vital_signs`/`features`/`classification` re-broadcasted the last-seen values indefinitely. Fix: clone the cached `latest_update` per tick, overwrite `source` with `s.effective_source()`, then serialize and broadcast. UI can now switch to an offline state on the same 5-second budget the REST surface uses.
+- **Proof replay (`archive/v1/data/proof/verify.py`) is now cross-platform deterministic** (closes #560). Three changes together: (1) `features_to_bytes()` now `np.round(.., HASH_QUANTIZATION_DECIMALS=6)`s each feature array before packing as little-endian f64, collapsing ULP-level drift from scipy.fft pocketfft SIMD reordering; (2) the `Verify Pipeline Determinism` workflow pins `OMP_NUM_THREADS=1`, `OPENBLAS_NUM_THREADS=1`, `MKL_NUM_THREADS=1`, `VECLIB_MAXIMUM_THREADS=1`, `NUMEXPR_NUM_THREADS=1` — multi-threaded BLAS reductions were a deeper source of non-determinism than SIMD reordering, and 6-decimal quantization alone wasn't enough across Azure VM microarchitectures; (3) `expected_features.sha256` regenerated under the new conditions. CI now passes the determinism check (same hash across consecutive runs on canonical Linux x86_64 CI runner: `667eb054c44ac510342665bf9c93d608868a8ead948ae8774b2796ebce6f8fe7`). `scripts/probe-fft-platform.py` updated to mirror `HASH_QUANTIZATION_DECIMALS=6` for cross-machine spot-checks.
+- **`archive/v1/src/services/pose_service.py:223` calls the right method on `PhaseSanitizer`** (closes #612). The call was `self.phase_sanitizer.sanitize(phase_data)`, but `PhaseSanitizer`'s full-pipeline entry point is named `sanitize_phase()` (`unwrap_phase` + `remove_outliers` + `smooth_phase` chained, see `archive/v1/src/core/phase_sanitizer.py:266`). The shorter `sanitize` name doesn't exist on the class, so any path that reached this branch raised `AttributeError` and crashed the pose service mid-frame.
+- **`adaptive_classifier.rs:94` no longer panics on NaN feature values** (closes #611).
+  `sorted.sort_by(|a, b| a.partial_cmp(b).unwrap())` returned `None` and panicked
+  whenever a single `NaN` reached the classifier from real ESP32 hardware (silent
+  DSP div-by-zero, empty buffer). One bad frame killed the entire sensing-server
+  process. Swapped for `unwrap_or(Ordering::Equal)`, matching the pattern the
+  same file already used at lines 149-150 and 155. Per-frame hot path; this was
+  a real production crash vector.
+- **Completed the #611 NaN-panic audit across the sensing-server crate** (follow-up
+  to #613). The original audit grepped for the literal `partial_cmp(b).unwrap()`
+  and missed seven additional production sites that use comparator variants
+  (`partial_cmp(b.1).unwrap()`, `partial_cmp(&variances[b]).unwrap()`). All share
+  the same crash class — a single `NaN` in CSI-derived state panics the whole
+  sensing-server. Fixed:
+  - `adaptive_classifier.rs:205` — `AdaptiveModel::classify()` argmax over softmax
+    probs. **Same per-frame hot path as #611**; NaN flows through normalise →
+    logits → softmax and still reaches this site even after the #613 IQR fix.
+  - `adaptive_classifier.rs:480, 500` — training-loop argmax in `train()`
+    (training/per-class accuracy reporting).
+  - `main.rs:2446, 2449` and `csi.rs:602, 605` — variance-based source/sink
+    selection in `count_persons_mincut`. The outer `unwrap_or((0, &0))` only
+    catches an empty iterator; it cannot rescue a comparator panic.
+
+  Remaining `partial_cmp(...).unwrap()` sites in the workspace are all inside
+  `#[cfg(test)]` / `#[test]` blocks (`spectrogram.rs:269`, `depth.rs:234`,
+  `connectivity.rs:477`, `vital_signs.rs:737`) where inputs are controlled.
+- **`ui/utils/pose-renderer.js` no longer divides by zero** when two render frames land in the same `performance.now()` tick (issue #519 Bug 2). `deltaTime` is now `Math.max(currentTime - lastFrameTime, 1)` before the `1000 / deltaTime` division, capping displayed FPS at 1000 — far above any real render rate, but finite so the EMA `averageFps = averageFps * 0.9 + fps * 0.1` no longer poisons itself to `Infinity` on a single zero-dt tick.
+
+### Removed
+- **Stub crates `wifi-densepose-api`, `wifi-densepose-db`, `wifi-densepose-config`** (closes #578).
+  Each was a single-line doc-comment placeholder with an empty `[dependencies]`
+  section and zero references from any source file or `Cargo.toml`. The names
+  were reserved early for an envisioned REST/database/config split that never
+  materialised; the functionality they would provide is covered today by
+  `wifi-densepose-sensing-server` (Axum REST/WS), per-crate config + CLI args,
+  and the project's real-time-only (no-persistent-state) posture. Removing them
+  from the workspace prevents `cargo` from listing dead crates and shipping
+  empty published artifacts. If any of these names is needed in the future,
+  they can be reintroduced with a real implementation.
+
+### Added
+- **Real-time CSI introspection / low-latency tap on `wifi-densepose-sensing-server` (ADR-099).**
+  New `wifi_densepose_sensing_server::introspection` module wires
+  [midstream](https://github.com/ruvnet/midstream)'s `temporal-attractor` (Lyapunov +
+  regime classification) and `temporal-compare` (DTW pattern matching) as a
+  **parallel tap** alongside RuView's existing event pipeline — no replacement,
+  no behaviour change to the existing `/ws/sensing` fan-out or `wifi-densepose-signal`
+  DSP. Two new endpoints (off by default, enabled via `--introspection`):
+  - `GET /ws/introspection` — newline-delimited JSON snapshots streamed at the CSI
+    frame rate. Each snapshot carries `frame_count`, `regime` (Idle / Periodic /
+    Transient / Chaotic / Unknown), `lyapunov_exponent`, `attractor_dim`,
+    `attractor_confidence`, `regime_changed` (boolean — flips on the first frame
+    after a regime transition), and `top_k_similarity[]` (highest-scoring
+    signature matches against a per-deployment library).
+  - `GET /api/v1/introspection/snapshot` — single-shot JSON snapshot, auth-gated
+    when `RUVIEW_API_TOKEN` is set.
+  Per-frame `update()` budget measured at **0.041 ms p99** on the I5 bench
+  (~24× under ADR-099 D4's 1 ms target). Shape-match latency on a 1-D
+  mean-amplitude L1 stand-in: **5 frames** (3.20× ratio vs the 16-frame event-path
+  floor). ADR-099 D8 honestly amended — the aspirational 10× bar is contingent on
+  ADR-208 Phase 2 multi-dim NPU embeddings; this release ships the tap off-by-default
+  while the foundation lands. 8 lib tests + 5 latency/regression tests (`tests/introspection_latency.rs`,
+  including a 200-frame noise warm-up → 10-frame motion-ramp signature benchmark).
+- **Opt-in bearer-token auth on `wifi-densepose-sensing-server`'s `/api/v1/*` HTTP surface (closes #443).**
+  New `wifi_densepose_sensing_server::bearer_auth` module: when the
+  `RUVIEW_API_TOKEN` env var is set, every request whose path begins with
+  `/api/v1/` must carry an `Authorization: Bearer <token>` header (constant-time
+  compared) or the server responds `401 Unauthorized`. When the variable is
+  unset or empty the middleware is a no-op — the long-standing LAN-only
+  deployment posture is preserved, so this is a binary deployment-time switch
+  with **no default behaviour change**. `/health*`, `/ws/sensing`, and the
+  `/ui/*` static mount are intentionally never gated (orchestrator probes +
+  local browsers). Startup logs which mode is active and warns when auth is on
+  with a `0.0.0.0` bind. 8 unit tests on the middleware (lib test count 191 → 199).
+  Resolves the security audit raised in #443.
+
+### Changed
+- **Docker image: build-time guard for the UI assets, plus a CI workflow that
+  rebuilds and pushes on every change (closes #520, #514).** `docker/Dockerfile.rust`
+  now `RUN`s a guard after `COPY ui/` that fails the build if any of
+  `index.html` / `observatory.html` / `pose-fusion.html` / `viz.html` / the
+  `observatory/` / `pose-fusion/` / `components/` / `services/` directories are
+  missing, so a stale image can never be silently produced again. New
+  `.github/workflows/sensing-server-docker.yml` builds the image on push to
+  `main` (paths-filtered) and on `v*` tags and pushes to both
+  `docker.io/ruvnet/wifi-densepose` and `ghcr.io/ruvnet/wifi-densepose` with
+  `latest` + `vX.Y.Z` + `sha-<short>` tags, then smoke-tests the published
+  artifact: `/health`, `/api/v1/info`, the observatory + pose-fusion UI assets,
+  and the `RUVIEW_API_TOKEN` auth path (no token → 401, wrong → 401, correct
+  → 200). Uses `DOCKERHUB_USERNAME` / `DOCKERHUB_TOKEN` repo secrets for the
+  Docker Hub push; ghcr.io uses the workflow's `GITHUB_TOKEN`.
+- **rvCSI moved to its own repo and is now vendored as a submodule.** The 9 `rvcsi-*`
+  crates (`rvcsi-core`/`-dsp`/`-events`/`-adapter-file`/`-adapter-nexmon`/`-ruvector`/
+  `-runtime`/`-node`/`-cli` — added inline in #542) now live in
+  [`github.com/ruvnet/rvcsi`](https://github.com/ruvnet/rvcsi): published to crates.io
+  as `rvcsi-* 0.3.x`, to npm as `@ruv/rvcsi`, with a Claude Code plugin marketplace and
+  a RuView-style README. RuView vendors it under `vendor/rvcsi` (alongside
+  `vendor/ruvector` / `vendor/midstream` / `vendor/sublinear-time-solver`) and no longer
+  carries inline copies in `v2/crates/`; consumers depend on the published crates (or the
+  submodule's `crates/rvcsi-*` paths). `v2/Cargo.toml`, `CLAUDE.md`, and the README docs
+  table updated accordingly. The ADRs (ADR-095, ADR-096), PRD, and DDD model stay in
+  `docs/` here as the design record of the incubation.
+
+### Fixed
+- **README: corrected the camera-supervised pose-accuracy claim.** The README stated
+  "92.9% PCK@20" for camera-supervised training; that figure does not appear in
+  ADR-079 and is ~2.6× the ADR's own success target (>35% PCK@20). ADR-079 phases
+  P7 (data collection), P8 (training + evaluation on real paired data) and P9
+  (cross-room LoRA) are still `Pending`, so no measured camera-supervised PCK@20 has
+  been published. README now states the proxy-supervised baseline (≈2.5%) and the
+  ADR-079 target (35%+), and notes the eval phases are pending. Surfaced by the
+  PowerPlatePulse training-pipeline audit (2026-05-11); 6 remaining audit findings
+  tracked in the PR.
+- **rvCSI `BaselineDriftDetector`: drift thresholds are now scale-relative, not absolute.**
+  The detector compared `mean_amplitude` against its EWMA baseline with absolute
+  thresholds (`anomaly_threshold = 1.0`, `drift_threshold = 0.15`) — fine for the
+  synthetic unit tests (amplitudes ≈ 1.0), but raw ESP32 CSI is `int8` I/Q with
+  amplitudes up to ~128, so the window-to-window RMS distance is routinely 5–50 ≫ 1.0
+  and `AnomalyDetected` fired on ~96 % of windows (319/331 on a real node-1 capture).
+  Drift is now `‖current − baseline‖₂ / ‖baseline‖₂` (a fraction, with an `eps` floor
+  for a degenerate near-zero baseline), so one tuning works across raw-`int8` ESP32,
+  `int16`-scaled Nexmon, and baseline-subtracted streams alike — `AnomalyDetected`
+  drops to 40/331 on the same data, the existing detector tests still pass, and a
+  `baseline_drift_is_scale_invariant_no_anomaly_storm` regression test was added.
+  ADR-095 D13 / ADR-096 §2.1, §5 updated. Surfaced by an end-to-end test against
+  real ESP32 CSI (a 7,000-frame node-1 capture; transcoder at
+  `scripts/esp32_jsonl_to_rvcsi.py`).

+- **rvCSI — edge RF sensing runtime (design + first implementation).** New subsystem **rvCSI**: a Rust-first / TypeScript-accessible / hardware-abstracted edge RF sensing runtime that normalizes WiFi CSI from Nexmon, ESP32, Intel, Atheros, file and replay sources into one validated `CsiFrame` schema, runs reusable DSP, emits typed confidence-scored events, and bridges to RuVector RF memory, an MCP tool server and a TS SDK.
+  - **Design docs:** `docs/prd/rvcsi-platform-prd.md` (purpose, users, success criteria, FR1–FR10, NFRs, system architecture, data model); `docs/adr/ADR-095-rvcsi-edge-rf-sensing-platform.md` (the 15 architectural decisions: Rust core, C-at-the-boundary, TS SDK via napi-rs, normalized schema, validate-before-FFI, CSI-as-temporal-delta, RuVector as RF memory, replayability, detection≠decision, local-first, read-first/write-gated MCP, mandatory quality scoring, versioned calibration, plugin adapters); `docs/adr/ADR-096-rvcsi-ffi-crate-layout.md` (crate topology, the napi-c shim record format & contract, the napi-rs Node surface, build/test invariants); `docs/ddd/rvcsi-domain-model.md` (7 bounded contexts: Capture, Validation, Signal, Calibration, Event, Memory, Agent — with aggregates, invariants, context map and domain services). Indexed in `docs/adr/README.md` and `docs/ddd/README.md`.
+  - **Crates** (9 new `v2/crates/rvcsi-*` workspace members): `rvcsi-core` (normalized `CsiFrame`/`CsiWindow`/`CsiEvent` schema, `AdapterProfile`, `CsiSource` plugin trait, id newtypes + `IdGenerator`, `RvcsiError`, the `validate_frame` pipeline + quality scoring; `forbid(unsafe_code)`); `rvcsi-adapter-nexmon` — the **napi-c** seam: `native/rvcsi_nexmon_shim.{c,h}` (the only C in the runtime — allocation-free, bounds-checked, ABI `1.1`), compiled via `build.rs`+`cc`, handling **two byte formats** — the compact self-describing "rvCSI Nexmon record", and the **real nexmon_csi UDP payload** (the 18-byte `magic 0x1111 · rssi · fctl · src_mac · seq · core/stream · chanspec · chip_ver` header + `nsub` int16 I/Q samples, the modern BCM43455c0/4358/4366c0 export read by CSIKit/`csireader.py`), with a Broadcom d11ac **chanspec decoder** (channel/bandwidth/band) — plus a pure-Rust **libpcap reader** (classic `.pcap`, all byte-order/timestamp-resolution magics, Ethernet/raw-IPv4/Linux-SLL link types) and a **Nexmon-chip / Raspberry-Pi-model registry** (`NexmonChip` / `RaspberryPiModel` — including the **Raspberry Pi 5** (CYW43455/BCM43455c0, same wireless as the Pi 4 — 20/40/80 MHz, 2.4+5 GHz, 64/128/256 subcarriers), the Pi 3B+/4/400, and the Pi Zero 2 W (BCM43436b0); `nexmon_adapter_profile` / `raspberry_pi_profile` build the per-chip `AdapterProfile`; `chip_ver` words auto-resolve to a chip). Wrapped by a documented `ffi` module and two `CsiSource`s: `NexmonAdapter` (record buffers) and `NexmonPcapAdapter` (real nexmon_csi UDP inside a `tcpdump -i wlan0 dst port 5500 -w csi.pcap` capture — the pcap timestamp stamps each frame; the chip is auto-detected from `chip_ver`, overridable via `.with_pi_model(Pi5)` / `.with_chip(...)`). `rvcsi-dsp` (DC removal, phase unwrap, smoothing, Hampel/MAD filter, sliding variance, baseline subtraction, motion-energy/presence/confidence features, heuristic breathing-band estimate, non-destructive `SignalPipeline`); `rvcsi-events` (`WindowBuffer`, the `EventDetector` trait + presence/motion/quality/baseline-drift state machines, `EventPipeline`; the baseline-drift detector uses **scale-relative** thresholds — drift as a fraction of the baseline's RMS magnitude — so one tuning works across raw-`int8` ESP32, `int16`-scaled Nexmon, and baseline-subtracted streams alike); `rvcsi-adapter-file` (the `.rvcsi` JSONL capture format, `FileRecorder`, `FileReplayAdapter` deterministic replay); `rvcsi-ruvector` (deterministic window/event embeddings, `cosine_similarity`, the `RfMemoryStore` trait, `InMemoryRfMemory` + `JsonlRfMemory` — a standin until the production RuVector binding); `rvcsi-runtime` (the no-FFI composition layer: `CaptureRuntime` = `CsiSource` + `validate_frame` + `SignalPipeline` + `EventPipeline`, plus one-shot helpers `summarize_capture`/`decode_nexmon_records`/`decode_nexmon_pcap`/`summarize_nexmon_pcap`/`events_from_capture`/`export_capture_to_rf_memory`); `rvcsi-node` — the **napi-rs** seam (a `["cdylib","rlib"]` Node addon, `build.rs` runs `napi_build::setup()`; thin `#[napi]` wrappers over `rvcsi-runtime` — `nexmonDecodeRecords`/`nexmonDecodePcap` (with optional `chip`)/`inspectNexmonPcap`/`decodeChanspec`/`nexmonChipName`/`nexmonProfile`/`nexmonChips`/`inspectCaptureFile`/`eventsFromCaptureFile`/`exportCaptureToRfMemory` + an `RvcsiRuntime` streaming class; everything that crosses to JS is a validated/normalized struct serialized to JSON); `rvcsi-cli` (the `rvcsi` binary: `record` (Nexmon-dump *or* `--source nexmon-pcap [--chip pi5]` → `.rvcsi`), `inspect`, `inspect-nexmon`, `nexmon-chips`, `decode-chanspec`, `replay`, `stream`, `events`, `health`, `calibrate` v0-baseline, `export ruvector`). Plus the `@ruv/rvcsi` npm package (`package.json`/`index.js`/`index.d.ts`/`README`/`__test__`) alongside `rvcsi-node` — a curated JS surface that parses the addon's JSON into plain `CsiFrame`/`CsiWindow`/`CsiEvent`/`SourceHealth`/`CaptureSummary`/`NexmonPcapSummary`/`DecodedChanspec` objects, with a lazy native-addon load.
+  - **Tests:** 169 across the rvcsi crates (core 29, dsp 28, events 19 — incl. a baseline-drift scale-invariance regression, adapter-file 20 + 1 doctest, adapter-nexmon 28 — round-tripping through the C shim and synthetic libpcap files, incl. Pi 5 / chip-detection, ruvector 20 + 1 doctest, runtime 13, cli 10), 0 failures; all rvcsi crates build together and are clippy-clean (`rvcsi-node` under `deny(clippy::all)`); `forbid(unsafe_code)` everywhere except `rvcsi-adapter-nexmon` (FFI, every `unsafe` block documented). Also exercised end-to-end against a real 7,000-frame ESP32 node-1 capture (transcoded with `scripts/esp32_jsonl_to_rvcsi.py` — the stand-in for the not-yet-shipped `record --source esp32-jsonl`): `rvcsi inspect`/`replay`/`calibrate`/`events` all run on real hardware data. Not yet wired in: live radio capture, `rvcsi-adapter-esp32` (live serial/UDP ESP32 source), the WebSocket daemon (`rvcsi-daemon`), the MCP tool server (`rvcsi-mcp`), and the legacy nexmon *packed-float* CSI export — follow-ups on top of these crates.
+- **`wifi-densepose-train`: `signal_features` module — wires `wifi-densepose-signal` into the training pipeline.** `wifi-densepose-signal` was previously a phantom dependency of `wifi-densepose-train` (listed in `Cargo.toml`, never imported). New `wifi_densepose_train::signal_features::extract_signal_features` (and `CsiSample::signal_features()`) run a windowed CSI observation's centre frame through `wifi_densepose_signal::features::FeatureExtractor`, producing a fixed-length (`FEATURE_LEN = 12`) amplitude/phase/PSD feature vector — the hook for a future vitals / multi-task supervision head (breathing- and heart-rate-band power are read off the PSD summary). The vector is produced on demand and not yet fed back into the loss. Surfaced by the 2026-05-11 training-pipeline audit (findings #1 "vitals features absent from training" and #2 "`wifi-densepose-signal` ghost dep").
+- **`wifi-densepose-train`: `TrainingConfig` subcarrier-layout presets + a real-loader integration test.** New `TrainingConfig::for_subcarriers(native, target)` plus named presets `ht40_192()` (≈192-sc ESP32 HT40 → 56) and `multiband_168()` (168-sc ADR-078 multi-band mesh → 56), so non-MM-Fi CSI shapes are first-class instead of requiring manual `native_subcarriers`/`num_subcarriers` overrides; field docs now list the supported source counts and the multi-NIC mapping. New `tests/test_real_loader.rs` round-trips synthetic CSI through `.npy` files → `MmFiDataset::discover`/`get` (including the subcarrier-interpolation branch and the empty-root case) — exercising the on-disk loader path the deterministic `verify-training` proof intentionally bypasses. Addresses training-pipeline audit findings #6 (56-sc/1-NIC config default) and #7 (multi-band mesh not in config); the #4 concern ("proof uses synthetic data") is reframed — the proof *should* use a reproducible source, and this test covers the real loader it skips.
+
+### Fixed
+- **HuggingFace `MODEL_CARD.md`: marked the PIR/BME280 environmental-sensor ground-truth path as planned, not implemented** (training-pipeline audit finding #3) — the card presented PIR/BME280 weak-label fine-tuning as a current capability; there is no env-sensor ingestion in the training pipeline today.
+- **README: corrected the camera-supervised pose-accuracy claim** (audit finding #5; see PR #535) — "92.9% PCK@20" → the ADR-079 target (35%+; proxy baseline 35.3%), noting P7/P8/P9 are pending.
+
+### Added
+- **`RollingP95` adaptive feature normalizer** (`v2/crates/wifi-densepose-sensing-server`) —
+  Streaming P95 estimator (600-sample / ~30 s sliding window) that self-calibrates
+  feature normalization to whatever distribution the deployment produces. Replaces
+  fixed-scale denominators (`variance/300`, `motion/250`, `spectral/500`) which saturated
+  when live ESP32 values exceeded those limits, collapsing dynamic range to zero.
+  Cold-start (<60 samples) falls back to the legacy denominators so day-0 behaviour
+  is preserved. Deployment-neutral: no hardcoded values. (ADR-044 §5.2)
+
+- **`dedup_factor` runtime configuration API** (`v2/crates/wifi-densepose-sensing-server`) —
+  Exposes the multi-node person-count deduplication divisor at runtime via REST:
+  - `GET  /api/v1/config/dedup-factor` — read current value.
+  - `POST /api/v1/config/dedup-factor` — set value (clamped 1.0–10.0, persisted).
+  - `POST /api/v1/config/ground-truth` — auto-tunes `dedup_factor` from a known
+    person count (`{"count": N}`); derives optimal divisor from current node-sum.
+  Config is persisted to `data/config.json` and reloaded on restart. (ADR-044 §5.3)
+
+- **`nvsim` crate — deterministic NV-diamond magnetometer pipeline simulator** (ADR-089) —
+  New standalone leaf crate at `v2/crates/nvsim` modeling a forward-only
+  magnetic sensing path: scene → source synthesis (Biot–Savart, dipole,
+  current loop, ferrous induced moment) → material attenuation
+  (Air/Drywall/Brick/Concrete/Reinforced/SteelSheet) → NV ensemble
+  (4 〈111〉 axes, ODMR linear-readout proxy, shot-noise floor per
+  Wolf 2015 / Barry 2020) → 16-bit ADC + lock-in demodulation →
+  fixed-layout `MagFrame` records → SHA-256 witness. Six-pass build
+  per `docs/research/quantum-sensing/15-nvsim-implementation-plan.md`.
+  50 tests, ~4.5 M samples/s on x86_64 (4500× the Cortex-A53 1 kHz
+  acceptance gate), pinned reference witness
+  `cc8de9b01b0ff5bd97a6c17848a3f156c174ea7589d0888164a441584ec593b4`
+  for byte-equivalence regression. WASM-ready by construction
+  (zero `std::time/fs/env/process/thread`); builds cleanly for
+  `wasm32-unknown-unknown`. ADR-090 (Proposed, conditional) tracks the
+  optional Lindblad/Hamiltonian extension if AC magnetometry, MW power
+  saturation, hyperfine spectroscopy, or pulsed protocols become required.
+
+### Fixed
+- **WebSocket broadcast handler now handles Lagged events gracefully and sends periodic ping keepalives to prevent dashboard disconnects** —
+  `handle_ws_client` and `handle_ws_pose_client` in `wifi-densepose-sensing-server`
+  were treating `RecvError::Lagged` as a fatal error, causing instant disconnect
+  when clients fell behind the 256-frame broadcast buffer at 10 Hz ingest.
+  Clients would reconnect, immediately lag again, and rapid-cycle every 2–4 s.
+  `Lagged` now continues (drops missed frames, logs debug) rather than breaking.
+  Added 30 s ping keepalive on the sensing handler to prevent proxy idle timeouts.

 ### Fixed
-- **`provision.py` esptool v5 compat** (#391) — Stale `write_flash` (underscore) syntax in the dry-run manual-flash hint now uses `write-flash` (hyphenated) for esptool >= 5.x. The primary flash command was already correct.
+- **Firmware: SPI flash cache crash under high CSI callback pressure** (RuView#396, #397) — ESP32-S3 nodes crashed in `cache_ll_l1_resume_icache` / `wDev_ProcessFiq` after ~2400 callbacks when the promiscuous filter admitted DATA frames at 100–500 Hz. Fixed by narrowing the filter mask to `WIFI_PROMIS_FILTER_MASK_MGMT` (~10 Hz beacons), adding a 50 Hz early callback rate gate (`CSI_MIN_PROCESS_INTERVAL_US`) that drops excess callbacks before any processing work, and enabling `CONFIG_ESP_WIFI_EXTRA_IRAM_OPT=y` as defense-in-depth. Stability validated with a 4-min-per-node soak.
+- **Firmware: `filter_mac` / `node_id` clobber by WiFi driver init** (#232, #375, #385, #386, #390, #397) — `g_nvs_config` can be corrupted during `wifi_init_sta()` on some devices (confirmed on `80:b5:4e:c1:be:b8`), reverting `node_id` to the Kconfig default and producing garbage MAC-filter reads in the CSI callback (100–500 Hz). New `csi_collector_set_node_id()` API called from `app_main()` **before** `wifi_init_sta()` captures both fields into module-local statics (`s_node_id`, `s_filter_mac`, `s_filter_mac_set`). `csi_collector_init()` now runs a canary that distinguishes "early≠g_nvs_config" (corruption confirmed) from a no-op match. All CSI runtime paths use the defensive copies exclusively.
+- **Firmware: `edge_processing` sample rate mismatch** (#397) — `estimate_bpm_zero_crossing()` was called with a hard-coded `sample_rate = 20.0f`, but MGMT-only promiscuous delivers ~10 Hz. Breathing and heart-rate reports were 2× too high. Corrected to `10.0f` with an explicit comment tying it to the callback rate.
+- **`provision.py` esptool command form** (#391, #397) — ESP-IDF v5.4 bundles `esptool 4.10.0`, which only accepts `write_flash` (underscore). Standalone `pip install esptool` v5.x accepts both forms but prefers `write-flash`. #391 switched to `write-flash` which broke the documented ESP-IDF Python venv flow; #397 reverts to `write_flash` (works with both esptool 4.x and 5.x) with an inline comment warning future maintainers not to "re-fix" it.
+- **`provision.py` esptool v5 dry-run hint** (#391) — Stale `write_flash` (underscore) syntax in the dry-run manual-flash hint now uses `write-flash` (hyphenated) for esptool >= 5.x. The primary flash command was already correct.
 - **`provision.py` silent NVS wipe** (#391) — The script replaces the entire `csi_cfg` NVS namespace on every run, so partial invocations were silently erasing WiFi credentials and causing `Retrying WiFi connection (10/10)` in the field. Now refuses to run without `--ssid`, `--password`, and `--target-ip` unless `--force-partial` is passed. `--force-partial` prints a warning listing which keys will be wiped.
 - **Firmware: defensive `node_id` capture** (#232, #375, #385, #386, #390) — Users on multi-node deployments reported `node_id` reverting to the Kconfig default (`1`) in UDP frames and in the `csi_collector` init log, despite NVS loading the correct value. The root cause (memory corruption of `g_nvs_config`) has not been definitively isolated, but the UDP frame header is now tamper-proof: `csi_collector_init()` captures `g_nvs_config.node_id` into a module-local `s_node_id` once, and `csi_serialize_frame()` plus all other consumers (`edge_processing.c`, `wasm_runtime.c`, `display_ui.c`, `swarm_bridge_init`) read it via the new `csi_collector_get_node_id()` accessor. A canary logs `WARN` if `g_nvs_config.node_id` diverges from `s_node_id` at end-of-init, helping isolate the upstream corruption path. Validated on attached ESP32-S3 (COM8): NVS `node_id=2` propagates through boot log, capture log, init log, and byte[4] of every UDP frame.

+    q: 'Is this a real simulator or a mockup?',

+  },
+  {
+    q: 'Why does my "Recovered |B|" sit much higher than "Predicted |B|" in the Ghost Murmur demo?',
+    a: 'The recovered value reads the simulator\'s ADC quantization floor, not the actual magnetic signal. With COTS-default sensor noise (~300 pT/√Hz) and 16-bit ADC at ±10 µT FS, anything below ~1 pT vanishes into ~2 nT of digitization residual. That\'s the lesson — the press claim sits far below this floor at any meaningful range.',
+  },
+  {
+    q: 'Can I run my own scene?',
+    a: 'Yes. Press ⌘K to open the command palette and pick "New scene…". You get five fields (name, dipole moment, distance, ferrous toggle, mains toggle); the dashboard builds the JSON and pushes it via <code>client.loadScene()</code>.',
+  },
+  {
+    q: 'Does any of my data leave the browser?',
+    a: 'No. WASM mode is local-only — the worker, the WASM binary, and the IndexedDB persistence all live in your browser. The optional WS transport (off by default) talks to a host of your choosing.',
+  },
+  {
+    q: 'What does the witness mismatch (red ✗) mean?',
+    a: 'The current build of nvsim produced a SHA-256 that doesn\'t match the constant pinned at compile time. Possible causes: a different Rust toolchain, a dependency version drift, a manual edit to a physics constant, or an honest bug. Audit the diff against ADR-089 §5.',
+  },
+  {
+    q: 'Why are the Inspector / Witness rail buttons there if there\'s already a right-side inspector?',
+    a: 'The right-side inspector is the compact live view; the rail buttons open a full-width version with bigger charts, an explainer header, reference-scene metadata cards, and (on Witness) a "what this verifies" panel. Both stay in sync — the right rail is for glancing, the main area is for diving in.',
+  },
+  {
+    q: 'Why is there an "App Store" if this is a magnetometer simulator?',
+    a: 'Because nvsim is one tile in a larger sensing platform. The catalog lists every hot-loadable WASM edge module RuView ships — medical, security, building, retail, industrial, signal, learning, autonomy. The simulators (nvsim today, more in future) are first-class entries in the same catalog.',

+      <p>The defining commitment is <b>determinism</b>: same <code>(scene, config, seed)</code> →
+        byte-identical SHA-256 witness across browsers, OSes, and transports. Press the
+        <kbd>Verify witness</kbd> button on the Witness tab to assert this live.</p>
+      <p>The codebase is open source (Apache-2.0 OR MIT). Find it on GitHub:
+        <code>github.com/ruvnet/RuView</code>. Decisions are documented in ADRs 089 (nvsim),

+        092 (this dashboard), 093 (UX gap analysis).</p>

 **Symptom:** Plugging into the right USB-C port (when facing the board with USB-C toward you) shows no serial device on the host.
 
 **Fix:** Use the left USB-C port. On most ESP32-S3-DevKitC boards, the left port is the USB-to-UART bridge (CP2102/CH340) used for flashing and serial monitor. The right port is the native USB (USB-JTAG) which requires different drivers and isn't used by the RuView firmware.

+
+## 9. Docker Desktop on Windows drops UDP from multiple ESP32 nodes
+
+**Symptom:** Two or more ESP32 nodes are flashed, provisioned, and visibly transmit on the network — `tcpdump`/Wireshark on the Windows host shows datagrams from every node — but inside the Docker container only one source IP arrives. `/api/v1/sensing/latest` shows a single node and the live UI freezes or only tracks one body. Reported in #374 (4-node bench) and reproduced in #386 (6-node demo, RuView v0.7.0).
+
+**Root cause:** Docker Desktop on Windows runs the engine inside a WSL2 / Hyper-V VM. Inbound UDP from the host LAN is forwarded through `vpnkit` / `vEthernet` and the multi-source-IP datagrams are demultiplexed onto a single virtual socket. The first source-IP "wins"; subsequent unique sources are silently dropped at the VM boundary. This is a Docker Desktop limitation, not a sensing-server bug — `host.docker.internal` and `--network host` do not help (host networking is not implemented for the Linux engine on Windows).
+
+**Fix:** Run the bundled UDP relay on the host so every forwarded datagram arrives from the same loopback source IP, which Docker passes through unchanged.
+
+```powershell
+# 1. Start the relay (PowerShell or any terminal)
+python scripts/udp-relay.py --listen-port 5005 --forward-port 5006
+
+# 2. Edit docker/docker-compose.yml — change the ESP32 UDP mapping from
+#       - "5005:5005/udp"
+#    to
+#       - "5006:5005/udp"
+
+# 3. Bring the stack up
+docker compose -f docker/docker-compose.yml up
+```
+
+ESP32 nodes still target the host on `--target-ip <host>:5005` — no firmware re-provisioning is needed. The relay is `scripts/udp-relay.py` (stdlib only, no extra deps). Verify with `--verbose` that each node's source IP appears at least once before forwarding stabilises on a single ephemeral relay port.
+
+**Prevention:** Linux and macOS hosts are unaffected; the relay only needs to run on Docker Desktop for Windows. If Docker Desktop ships per-source UDP forwarding (tracked at [docker/for-win#1144](https://github.com/docker/for-win/issues/1144) and related), this workaround can be retired.
+
+**Prior art:** PR #413 (`txhno`) proposed a docs-only writeup of the same workaround; this entry supersedes it.
+
+---
+
+## 10. `404` on the visualization page when running sensing-server
+
+**Symptom:** `sensing-server` starts cleanly, logs `HTTP server listening on http://localhost:3000`, but loading `http://localhost:3000/` (or `/ui/index.html`) returns `404 Not Found`. Reported in #188.
+
+**Root cause:** The default `--ui-path ../../ui` is resolved relative to the binary's *current working directory*, not the binary location. When the binary is launched from anywhere other than `crates/wifi-densepose-sensing-server/`, the relative path doesn't reach the UI assets and Axum's static file handler returns 404.
+
+**Fix:** Pass an absolute UI path, run the binary from the crate directory, or use the Docker image (which bundles the UI under `/app/ui`).
+
+```bash
+# Option A — absolute path (recommended for production)
+sensing-server --source esp32 --udp-port 5005 --http-port 3000 \
+  --ws-port 3001 --ui-path /absolute/path/to/ui
+
+# Option B — run from the crate dir (works for local dev / cargo run)
+cd v2/crates/wifi-densepose-sensing-server
+cargo run -- --source esp32
+
+# Option C — Docker (no path config needed)
+docker compose -f docker/docker-compose.yml up sensing-server
+```
+
+**Prevention:** Track future work in #188 to fall back to a path resolved relative to the executable when the cwd-relative path doesn't exist, so the binary works regardless of where it's launched.
+
+---
+
+## 11. Boot loop on `--edge-tier 1` or `--edge-tier 2`
+
+**Symptom:** ESP32-S3 boots normally with `--edge-tier 0`, but flashing the same firmware with `--edge-tier 1` or `2` produces a boot loop. Serial output reaches `cpu_start` and `heap_init`, then resets repeatedly. Reported in #438 against firmware `v0.4.3.1-esp32-3-g66e2fa083-dir`.
+
+**Root cause:** Edge tiers 1 and 2 enable the on-device DSP pipeline on Core 1. In the affected build, the `edge_dsp` task ran a tight per-frame loop without yielding, so the FreeRTOS task watchdog tripped on Core 1 and panicked. Tier 0 is passthrough only and doesn't activate the pipeline, so the watchdog never fires there.
+
+**Fix:** Flash the [v0.4.3.1-esp32](https://github.com/ruvnet/RuView/releases/tag/v0.4.3.1-esp32) release or later — the DSP task yield fixes have shipped on `main` since the build in the report.
+
+```bash
+# Verify what version you're on (look for "App version" in serial output on boot)
+python -m serial.tools.miniterm COM7 115200
+# Expect: "App version: v0.4.3.1-esp32" or higher
+```
+
+If the boot loop persists on a release build, capture a full serial trace including the watchdog backtrace and reopen #438 with the new build hash.

+
+## Context
+
+`docs/research/quantum-sensing/14-nv-diamond-sensor-simulator.md` surveyed
+the state of NV-diamond magnetometry hardware and software in 2026 and
+landed on a "lean toward skip" verdict for a RuView NV-simulator absent a
+hardware target. That verdict was honest: the COTS NV-diamond noise floor
+(~300 pT/√Hz at the Element Six DNV-B1 price point) is 1–2 orders of
+magnitude worse than QuSpin OPMs at similar cost, so a *biomagnetic-grade*
+NV simulator would be choosing the wrong modality.
+
+The user nonetheless chose to build the simulator, with two non-biomagnetic
+use cases in mind:
+
+1. **Forward simulation for ferrous-anomaly / metallic-object detection** —
+   where NV-diamond's vector readout and unshielded-room operation matter
+   more than absolute sensitivity, and the 1–10 nT range relevant to
+   detecting steel rebar / vehicles / firearms is well within COTS reach.
+2. **Open-source educational + reference implementation** — no published
+   open-source end-to-end NV pipeline simulator exists (`14.md` §2.2 gap).
+   QuTiP covers spin Hamiltonians; Magpylib covers analytic dipole +
+   Biot–Savart; nothing covers source → propagation → ODMR → ADC → witness
+   in one tool.
+
+`docs/research/quantum-sensing/15-nvsim-implementation-plan.md` produced
+the executable build spec — six passes, one module per pass, each pass
+shippable independently with a measured acceptance gate.
+
+## Decision
+
+Build `nvsim` as a **standalone Rust leaf crate** at `v2/crates/nvsim/`
+implementing the six-pass plan in doc 15. The crate is deliberately
+independent of the rest of the RuView workspace — no internal dependencies
+on `wifi-densepose-core`, `wifi-densepose-signal`, or `wifi-densepose-mat`,
+because the simulator is generally useful outside RuView's WiFi-CSI
+context (magnetic-anomaly modelling, NV-physics teaching, COTS sensor
+noise-floor sanity checks).
+
+Six-pass implementation:
+
+1. **Scaffold + scene + frame** — `Scene`, `DipoleSource`, `CurrentLoop`,
+   `FerrousObject`, `EddyCurrent` aggregate types; `MagFrame` 60-byte
+   binary record with magic `0xC51A_6E70`.
+2. **Source synthesis** — closed-form analytic dipole + numerical
+   Biot–Savart over current loops + linearly-induced ferrous moment
+   (Jackson 3e §5.4–5.6; Cullity & Graham 2e §2; Magpylib reference
+   per Ortner & Bandeira 2020).
+3. **Propagation** — per-material attenuation table (Air, Drywall,
+   Brick, ConcreteDry, ReinforcedConcrete, SheetSteel) with
+   conjectural defaults explicitly flagged where no primary source
+   exists at RuView geometry.
+4. **NV ensemble sensor** — Lorentzian ODMR lineshape at FWHM ≈ 1 MHz,
+   shot-noise floor `δB ∝ 1/(γ_e · C · √(N · t · T₂*))`, T₂ decay
+   envelope, 4-axis 〈111〉 crystallographic projection with
+   closed-form `(AᵀA) = (4/3)I` LSQ inversion. Defaults match Barry
+   et al. *Rev. Mod. Phys.* 92 (2020) Table III for COTS bulk diamond.
+5. **Digitiser + pipeline** — 16-bit signed ADC at ±10 µT FS,
+   1st-order IIR anti-alias at f_s/2.5, lockin demod at f_mod = 1 kHz
+   with f_s/1000 LP cutoff, end-to-end `Pipeline::run_with_witness`
+   producing a deterministic SHA-256 over the frame stream.
+6. **Proof bundle + criterion bench** — *pending next iteration*.
+
+Determinism is the load-bearing property: same `(scene, config, seed)`
+must produce byte-identical output across runs and machines. Underwritten
+by ChaCha20-seeded shot noise (no global PRNG state, no time-of-day
+field, no allocator randomness in the hot path) and verified in the
+test suite.
+
+## Consequences
+
+### Positive
+
+- **Open-source end-to-end NV pipeline simulator now exists** — closes
+  the gap `14.md` §2.2 identified.
+- **Deterministic CI gate**: any future change to the physics constants
+  shifts the SHA-256 witness, surfacing as a test failure rather than
+  silent drift.
+- **Honest physics**: every formula cited (Jackson, Doherty, Barry, Wolf,
+  Cullity & Graham, Ortner & Bandeira); every conjectural default flagged
+  in code; the Wolf 2015 sanity-floor test is the canary that fires if
+  anyone silently changes the ensemble constants.
+- **Standalone leaf**: no internal RuView dependencies, so anyone outside
+  RuView can use the crate as-is. RuView integrations land behind opt-in
+  feature flags.
+- **Forward-simulation niche filled**: gives DSP / ML engineers a known-
+  answer-key stream for regression replay without sourcing a magnetic
+  anomaly chamber.
+
+### Negative / risks
+
+- **Wrong modality risk**: per `14.md`, NV-diamond at COTS price points
+  is 1–2 orders of magnitude worse than OPM in the biomagnetic band.
+  Anyone using nvsim as a stand-in for biomagnetic sensing will get
+  optimistic noise-floor numbers relative to what the same money buys
+  in QuSpin OPMs. Mitigated by the Wolf 2015 sanity-floor test and
+  the README's explicit "if you need fT-floor sensitivity, this is
+  the wrong starting point" caveat.
+- **Conjectural propagation defaults**: drywall / brick / dry-concrete
+  loss values are conjectural; no systematic primary source exists for
+  residential-wall magnetic-field penetration loss at RuView geometry.
+  Flagged in code and in `15.md` §2.2; the `HEAVY_ATTENUATION` flag
+  surfaces this to downstream consumers.
+- **No pulsed-protocol simulation**: Rabi nutation, Hahn echo, dynamical
+  decoupling are out of scope. If a use case needs them, the Lindblad
+  extension lives in **ADR-090** (Proposed, conditional).
+- **Maintenance debt**: 1,800+ LoC of crystallographically-correct
+  physics code is non-trivial to maintain. Mitigated by the
+  Barry-2020-anchored test suite — drift in the constants surfaces
+  as a test failure within ~ms.
+
+### Neutral
+
+- ESP32-S3 firmware is **untouched** by this work — `nvsim` is host-side
+  only. Existing firmware tags (`v0.6.2-esp32`) continue to ship
+  unchanged.
+- The crate uses workspace-pinned dependencies (`ndarray`, `serde`,
+  `thiserror`, `rand`, `rand_chacha`, `sha2`); no new top-level
+  dependencies added.
+- ADR-086 (edge novelty gate, firmware track) is independent of this
+  ADR — its `0xC51A_6E70` `MagFrame` magic is distinct from ADR-018's
+  CSI magic and ADR-084's sketch magic.

+  suite. Whether that lives in-tree or as a separately-tagged release
+  artifact is a Pass-6 design choice.

+
+## Context
+
+[ADR-089](ADR-089-nvsim-nv-diamond-simulator.md)'s `nvsim::sensor` module
+implements a **leading-order linear-readout proxy** for NV-ensemble
+magnetometry per Barry et al. *Rev. Mod. Phys.* 92, 015004 (2020) §III.A.
+That paper validates the proxy as adequate for ensemble magnetometers in
+the **linear regime** — which is the CW-ODMR regime RuView's actual
+use case operates in. The Wolf 2015 sanity-floor test confirms the
+implementation matches published bulk-diamond results within 4×.
+
+What the proxy does *not* model:
+
+- **Pulsed protocols**: Rabi nutation, Hahn echo, CPMG / XY-N dynamical
+  decoupling sequences.
+- **Microwave-power saturation**: line-broadening at high CW MW power.
+- **Hyperfine structure**: ¹⁴N (I=1) and ¹⁵N (I=½) nuclear spin couplings
+  to the NV electronic spin.
+- **Coherent control**: Ramsey-style phase-accumulation experiments,
+  spin-echo magnetometry.
+
+For RuView's CW-ODMR ensemble use case (ferrous-anomaly detection,
+metallic-object screening), none of these matter — Barry 2020 §III.A is
+explicit that the linear-readout proxy is adequate. For *future* use cases
+that involve pulsed protocols (e.g., AC-magnetometry via Hahn echo to push
+sensitivity past the T₂* floor), they would matter.
+
+This ADR documents that decision-tree explicitly: **the Lindblad solver is
+not built unless and until a pulsed-protocol use case opens**.
+
+## Decision
+
+Defer the full Hamiltonian + Lindblad solver to a **conditional, opt-in
+feature gate** named `lindblad` on the `nvsim` crate. Default-off so that
+the existing fast linear-readout path stays the default and the build /
+test budget is unaffected. The ADR is **Proposed** — actual implementation
+happens only if a triggering use case meets the gate below.
+
+### Trigger conditions for promoting to Accepted
+
+This ADR transitions from Proposed → Accepted when **any one** of the
+following is true:
+
+1. A use case needs **AC magnetometry**: a Hahn-echo or CPMG / XY-N
+   dynamical-decoupling protocol where the answer cannot be approximated
+   by the linear proxy because T₂* is no longer the relevant timescale.
+2. A use case needs **microwave-power saturation modelling**: the
+   simulator is asked to predict the ODMR contrast as a function of MW
+   drive amplitude, which the linear proxy does not capture.
+3. A use case needs **hyperfine spectroscopy**: the simulator is asked to
+   reproduce the ¹⁴N or ¹⁵N hyperfine triplet visible in high-resolution
+   ODMR scans, which the linear proxy collapses.
+4. A use case needs **pulsed quantum-sensing protocols** more broadly:
+   Ramsey, spin-echo magnetometry, double-quantum coherence, etc.
+
+If none of those triggers, the linear proxy is sufficient and this ADR
+remains Proposed indefinitely.
+
+### Why the deferral is the right call today
+
+- **Adequacy validated by primary source.** Barry 2020 §III.A explicitly
+  validates the linear-readout proxy for ensemble magnetometers in the
+  linear regime. nvsim's existing `sensor.rs` matches Wolf 2015 within 4×.
+  We're not under-modelling — we're correctly-modelling.
+- **3–7 days of focused work.** The implementation cost is non-trivial:
+  density-matrix RK4 integrator over a 3-level (or 9-level with hyperfine)
+  Hilbert space, careful sign / basis / normalisation conventions,
+  validation against a published QuTiP reference script. The downside of
+  building it pre-emptively is paying that cost without a downstream
+  consumer.
+- **No current downstream consumer.** RuView's MAT (Mass Casualty
+  Assessment) consumer needs CW-ODMR ferrous anomaly detection, not
+  pulsed protocols. ADR-066 swarm-bridge (proposed) is similarly
+  CW-amplitude-only.
+- **Not blocked.** When a triggering use case appears, the work is well-
+  scoped and the build path is documented (see Implementation below).
+  Deferral is reversible at any time.
+
+### Why we don't just delegate to QuTiP
+
+QuTiP is the obvious off-the-shelf option and is what `15.md` §6 originally
+proposed deferring to. Two reasons we'd prefer an in-tree Rust
+implementation if we ever build it:
+
+1. **Determinism**. QuTiP runs in Python with potentially non-deterministic
+   ODE solver scheduling depending on threading, BLAS backend, and
+   NumPy version. nvsim's whole-pipeline determinism — same seed →
+   byte-identical witness — would be much harder to maintain across the
+   Python boundary.
+2. **CI integration**. The Rust workspace's `cargo test --workspace
+   --no-default-features` already runs in seconds. Adding QuTiP would
+   pull a Python dependency into CI and slow the gate.
+
+If a triggering use case opens but the cost-benefit doesn't justify in-
+tree implementation, an external QuTiP harness with cached fixture
+outputs is a viable fallback.
+
+## Consequences
+
+### Positive
+
+- **No premature engineering.** 3–7 days of work not spent on a feature
+  with no consumer; that time goes to Pass 6 of nvsim and to ADR-066
+  swarm-bridge work that has actual downstream demand.
+- **Honest scope.** ADR-089's README and the `nvsim::sensor` module
+  docstrings already say what's *not* modelled. ADR-090 is the
+  formal accountability for that boundary.
+- **Reversible.** All four trigger conditions are observable; if any
+  fires, the ADR moves to Accepted and the work begins.
+
+### Negative / risks
+
+- **Risk of premature commitment if triggers fire.** If pulsed-protocol
+  use cases emerge late in the project (e.g., a contributor wants
+  Hahn-echo magnetometry for academic-paper reproducibility), the 3–7-day
+  cost lands at an inconvenient time. Mitigated by the work being
+  well-scoped and bench-bounded — see Implementation.
+- **Documentation debt.** Every nvsim contributor should be aware that
+  pulsed protocols are out of scope. This ADR is the canonical reference
+  but its Proposed status means contributors might not read it. Mitigated
+  by the README's explicit "out of scope" section linking to this ADR.
+
+### Neutral
+
+- The existing linear-readout proxy is already feature-flag-free and
+  always-on; no API changes when ADR-090 lands. The Lindblad path is
+  additive.
+
+## Implementation (when triggered)
+
+If this ADR transitions to Accepted, the implementation is:
+
+1. **Add `lindblad` feature to `nvsim/Cargo.toml`** — opt-in, default-off.
+   Pulls `ndarray` (already a dep) + `num-complex` (already a workspace
+   dep) for complex-matrix algebra.
+2. **`src/lindblad.rs`** — new module, ≤ 600 LoC:
+   - `NvHamiltonian` — D·Sz² + γ_e·B·S + E·(Sx²−Sy²) on the m_s ∈ {−1, 0, +1}
+     ground-state basis. Optional ¹⁴N or ¹⁵N hyperfine extension.
+   - `LindbladOps` — collapse operators for T₁ (population relaxation,
+     L_∓ between m_s levels) and T₂ (pure dephasing on m_s = ±1).
+   - `LindbladIntegrator::rk4_step(rho, dt)` — fourth-order Runge-Kutta
+     time-step on the density matrix.
+   - `Pulse` enum — supports CW, square, Gaussian-shaped MW pulses.
+3. **`src/lindblad_protocols.rs`** — new module, ≤ 400 LoC:
+   - `Rabi::run` — fixed MW amplitude sweep, returns nutation curve.
+   - `HahnEcho::run` — π/2 — τ — π — τ — π/2 detection sequence.
+   - `Cpmg::run` — repeated π pulses for dynamical decoupling.
+4. **Validation suite** — mandatory before merging:
+   - Reproduce a published QuTiP reference Rabi curve (e.g., from a
+     Doherty 2013 supplementary script) within 1% per-bin error.
+   - Reproduce a Hahn-echo decay against published T₂ measurement
+     within 5%.
+   - Reproduce hyperfine triplet splitting against measured A_∥ /
+     A_⊥ values from Doherty 2013 §3.4.
+5. **Benchmarks** — criterion target: ≥ 100 Hz simulated Rabi-curve
+   evaluation on x86_64 (10× slower than the linear proxy is acceptable).
+6. **README + ADR update** — promote ADR-089's README "not yet shipped"
+   section to include the new pulsed-protocol capabilities, and move
+   this ADR to Accepted with the merge commit.
+
+Estimated effort: **3–7 days of focused work**, dominated by validation
+not implementation.
+
+## Validation (Proposed → Accepted)
+
+This ADR is **Proposed** until any of the four trigger conditions in §"
+Trigger conditions" fires. When that happens:
+
+1. Open a follow-up issue stating which trigger fired and which use case
+   needs Lindblad.
+2. The implementation §1–6 above defines the build.
+3. Acceptance moves on the validation-suite criteria in step 4 (1% Rabi
+   curve, 5% Hahn-echo decay, hyperfine triplet match).
+4. Merge promotes this ADR Proposed → Accepted with the new measured
+   numbers.
+
+## Open questions
+
+- **Which Rust complex-matrix library is the right substrate?** Three
+  candidates: (a) `ndarray` + `num-complex` (already workspace deps; lowest
+  surface area but unergonomic for matrix algebra); (b) `nalgebra` with
+  `ComplexField` trait (richer matrix algebra, +1 workspace dep);
+  (c) `faer` (more recent, focused on numerics performance, +1 workspace
+  dep). Decide at trigger time based on which best supports the Lindblad
+  RK4 step ergonomically and which version-pinning matches the workspace
+  conservatism.
+- **Is hyperfine modelling in v1 or v2?** A pure 3-level NV ground-state
+  Hamiltonian is sufficient for Rabi and Hahn echo. ¹⁴N hyperfine triplet
+  needs 9-level Hilbert space (3 m_s × 3 m_I), 9× more matrix work. v1
+  could ship with hyperfine off behind a sub-feature; v2 enables it.
+- **Should the Lindblad solver back-validate the linear proxy?** Once
+  Lindblad exists, it could be used to measure the proxy's error
+  envelope across operating points and tighten or loosen the existing
+  Wolf 2015 4× sanity floor accordingly. This is the strongest scientific
+  reason to build Lindblad even without an immediate use case — but
+  "validate the proxy" is itself the use case, so still meets trigger #4.
+
+## Related
+
+- **ADR-089** — nvsim NV-diamond simulator. The crate this extension
+  attaches to.
+- **ADR-018** — CSI binary frame format. Lindblad output would still flow
+  through the existing `MagFrame` (`0xC51A_6E70`) shape; pulsed-protocol
+  results add to the per-frame metadata, not a new frame format.
+- **ADR-028** — ESP32 capability audit. Lindblad is host-side only; ESP32
+  firmware untouched.
+- **ADR-066** — Swarm bridge. If the simulator is used for swarm-routed
+  AC-magnetometry experiments, this ADR's outputs flow through that
+  channel.

+
+## 1. Context
+
+### 1.1 Why this question now
+
+On Good Friday 3 April 2026 the press reported a CIA system called "Ghost Murmur"
+— a Lockheed Skunk Works NV-diamond + AI sensor reportedly used in the recovery
+of an F-15E pilot in southern Iran. President Trump publicly suggested detection
+ranges in the "tens of miles" against a single human heartbeat. RuView shipped
+a research spec (`16-ghost-murmur-ruview-spec.md`) which (a) reality-checked the
+press claims against published physics, (b) mapped the *honestly-scoped* version
+onto the existing RuView three-tier mesh, and (c) explicitly deferred one
+modality — high-power and sub-THz coherent radar — as out of scope. From §6.3
+of that spec:
+
+> 77 GHz automotive radars at higher power and 100–200 GHz coherent sub-THz
+> radars **can** resolve cardiac micro-Doppler at 50–500 m in clear LOS. These
+> are not COTS at the $15 price point and are not in the RuView stack today.
+> They are also subject to ITAR / export-control review and **explicitly out of
+> scope** for this open-source project.
+
+That sentence is the trigger for this ADR. We need a written, citable record of
+*why* the decision is "out of scope today", what would change the decision,
+and — crucially — what shape any future research entry into this band would
+take, given that even the research itself touches dual-use territory.
+
+### 1.2 What gap a higher-frequency / higher-power tier would close
+
+RuView's existing modality coverage (per the CLAUDE.md crate table):
+
+| Modality | Crate / ADR | Honest LOS range for HR | Through-wall HR |
+|---|---|---|---|
+| WiFi CSI 2.4/5/6 GHz | `wifi-densepose-signal`, ADR-014, ADR-029 | 1–3 m (presence to 30 m) | 1 wall, weak |
+| 60 GHz FMCW (MR60BHA2) | `wifi-densepose-vitals`, ADR-021 | 1–10 m | drywall only |
+| NV-diamond magnetometer | `nvsim` (simulator), ADR-089/090 | <1 m (gradiometric, shielded) | n/a |
+
+The ceiling of this stack on cardiac micro-Doppler in clear line-of-sight is
+**~10 m** (60 GHz tier, ADR-021 / spec §6.1). A higher-frequency / higher-power
+tier would, in principle, close the 10–500 m gap that the published radar
+literature has already explored. The two candidate bands:
+
+1. **77–81 GHz at higher than typical commercial EIRP** — the same band as
+   automotive radar, where the FCC ceiling is 50 dBm average / 55 dBm peak EIRP
+   under 47 CFR §95.M, and where published academic work has measured HR at
+   ranges beyond the typical 1–3 m used by COTS automotive sensors.
+2. **100–200 GHz coherent sub-THz radar** — where λ ≈ 1.5–3 mm gives
+   sub-millimetre chest-wall displacement resolution and where atmospheric
+   transmission windows at 94 GHz, 140 GHz, and 220 GHz make stand-off sensing
+   physically possible (with caveats on humidity, antenna gain, and integration
+   time).
+
+This ADR examines both bands — the SOTA, the COTS reality, the regulatory
+envelope, the physics ceiling, the export-control posture, and the open-source
+ethics — and lands at a build / research / skip recommendation per row.
+
+## 2. SOTA: 77–81 GHz automotive radar at higher power
+
+### 2.1 Current COTS chips at the $20–$200 price point
+
+The 76–81 GHz band is now densely populated with single-chip CMOS / SiGe
+transceivers. Representative parts:
+
+| Chip | Vendor | Tx / Rx | IF BW | Notes |
+|---|---|---|---|---|
+| AWR1843 | Texas Instruments | 3 Tx / 4 Rx | up to ~10 MHz IF | Single-chip 76–81 GHz with on-die DSP, MCU, radar accelerator. Long-range automotive ACC, AEB. ([TI AWR1843](https://www.ti.com/product/AWR1843)) |
+| AWR2243 | Texas Instruments | 3 Tx / 4 Rx | up to ~20 MHz IF | Cascadable for higher angular resolution (up to 12 Tx / 16 Rx with multi-chip cascade). ([TI AWR2243](https://www.ti.com/product/AWR2243)) |
+| BGT60 family | Infineon | 1–3 Tx / 1–4 Rx | Several MHz IF | 60 GHz primarily; BGT24 family at 24 GHz. Smaller, lower power, gesture / presence focus. |
+| TEF82xx | NXP | up to 4 Tx / 4 Rx | several MHz IF | Automotive-grade 76–81 GHz. |
+
+COTS evaluation boards (TI AWR1843BOOST, AWR2243 cascade kits) sit in the
+$300–$3,000 range; single-board production costs trend toward $20–$100 at
+volume. None of these chips is, by itself, export-controlled at typical
+configurations — the band is allocated for civilian automotive use under FCC
+Part 95 Subpart M and ETSI EN 301 091 in Europe.
+
+**EIRP envelope**: 47 CFR §95.M (and the historical §15.253 it replaced) caps
+the 76–81 GHz band at **50 dBm average / 55 dBm peak EIRP** measured in 1 MHz
+RBW ([Federal Register notice 2017](https://www.federalregister.gov/documents/2017/09/20/2017-18463/permitting-radar-services-in-the-76-81-ghz-band),
+[eCFR 47 CFR Part 95 Subpart M](https://www.ecfr.gov/current/title-47/chapter-I/subchapter-D/part-95/subpart-M)).
+That is roughly 100 W EIRP average, 316 W peak. COTS automotive radars
+typically operate well below this — single-digit dBm transmit power is
+multiplied by ~25–30 dBi antenna gain to land at 33–40 dBm EIRP.
+
+### 2.2 What "higher power" actually means in regulatory terms
+
+Three regulatory paths exist for an open-source project that wants to push
+beyond typical commercial deployment power:
+
+1. **Stay inside FCC Part 95 §95.M caps (50 dBm avg / 55 dBm peak EIRP)** —
+   licence-by-rule, no application, no individual approval. The headroom from
+   typical automotive EIRP (~33–40 dBm) to the cap (50 dBm avg) is real:
+   ~10 dB of additional EIRP is available *without changing licence class*,
+   purely by using a higher-gain dish or higher Tx power within the existing
+   chip. This is the upper bound of "stand-off radar that is still part-95
+   legal".
+2. **FCC Part 5 experimental licence** — needed for transmit power, antenna
+   gain, or duty-cycle that exceeds §95.M. Application-based, time-bounded,
+   non-renewable beyond limits. Typical academic radar ranges (e.g. the
+   long-range cardiac measurements in §2.3 below) operate under this regime.
+3. **No US authorisation at all** — only legal as receive-only, or as a
+   simulator. Any unlicensed transmission above §95.M at 76–81 GHz is a
+   prohibited emission under 47 CFR §15.5 / §95.335.
+
+For an *open-source mesh node* shipping to anonymous users worldwide, only
+path (1) is defensible. Anything that requires an individual experimental
+licence cannot be "ship a binary and let people flash it".

+  ([PMC9104941](https://pmc.ncbi.nlm.nih.gov/articles/PMC9104941/))
+
+The most cited *long-range* radar cardiac measurement is at 24 GHz, not 77 GHz:
+
+- **Massagram, W., Lubecke, V. M., Høst-Madsen, A., Boric-Lubecke, O. (2013).
+  "Parametric Study of Antennas for Long Range Doppler Radar Heart Rate
+  Detection."** *IEEE EMBC* / republished in *PMC*.
+  ([PMC4900816](https://pmc.ncbi.nlm.nih.gov/articles/PMC4900816/),
+  [PubMed 23366747](https://pubmed.ncbi.nlm.nih.gov/23366747/)) —
+  measured human HR at distances of **1, 3, 6, 9, 12, 15, 18, 21 m** and
+  respiration to **69 m** with a PA24-16 antenna at **24 GHz CW Doppler**.
+  This is the ceiling reference for "what's achievable with serious antenna
+  gain in clear LOS, low band, with subject cued and stationary".
+
+We could not find an equivalent peer-reviewed cardiac measurement at 77 GHz
+*beyond ~5 m* with a verifiable antenna gain × power × integration-time
+budget. The work that exists at 77 GHz is overwhelmingly bench-scale (≤ 2 m).
+This is itself informative: it suggests that *the open published frontier at
+77 GHz beyond 5 m is sparse*, not because it's impossible, but because the
+research community working at automotive bands has been focused on automotive
+problems (collision avoidance, in-cabin occupancy) where 5 m suffices, and
+because higher-range cardiac work has historically used 24 GHz where the
+antenna size for a given gain is more practical.
+
+### 2.4 Detection range as a function of antenna gain × power × integration time
+
+The radar equation for chest-wall displacement detection scales roughly as:
+
+```
+SNR ∝ (P_t · G_t · G_r · σ_chest) / (R^4 · k T B · NF) · √(t_int / T_coh)
+```
+
+where σ_chest ≈ 10⁻³–10⁻² m² for the cardiac scatterer at 77 GHz, NF ≈ 10–15 dB
+on COTS chips, and integration time t_int is bounded by T_coh ≈ 0.5–1 s
+(physiological coherence — the heart period itself).
+
+Doubling range requires 12 dB of system gain (4-th power dependence on R,
+two-way). At the part-95 §95.M ceiling (50 dBm avg EIRP) and a generous 30 dB
+antenna gain (a ~30 cm dish at 77 GHz), the addressable HR detection range in
+clear LOS is roughly **15–30 m for a stationary cued subject**, dropping to
+3–10 m for an uncued subject in light clutter. Pushing to 100 m+ in an open
+field would require either (a) a much larger antenna (60+ cm dish), (b)
+out-of-band EIRP beyond §95.M (experimental licence territory), or (c) much
+longer integration (incompatible with cardiac coherence times).
+
+The 2013 Massagram paper achieves 21 m at 24 GHz with a high-gain antenna
+under tightly controlled conditions. Pushing the same setup to 77 GHz with
+the same antenna *aperture* would actually help (smaller beamwidth, same
+free-space path loss), but the chest-wall RCS at 77 GHz is comparable, and
+clutter / multipath are much harsher. We have **no public reference** for a
+77 GHz cardiac measurement at 21 m that we could find with the same rigour.
+
+### 2.5 Cost ceiling for an open-source mesh node
+
+An open-source mesh node spec implies "ships in a kit, does not require
+individual licensing, fits the existing PoE / mini-PC edge model". That
+implies:
+
+- Single-chip transceiver at $20–$100 BOM.
+- Antenna assembly at $50–$200 (high-gain dish or printed array).
+- Mini-PC or Pi 5 host at $80.
+- Total under $500 to be plausible.
+
+The chip cost is already met by COTS. The antenna and host are met. The
+bottleneck is *not* hardware cost — it is regulatory exposure, dual-use
+ethics, and the fact that the addressable range at part-95 ceilings (15–30 m)
+is *only marginally beyond* what the existing 60 GHz tier already does for
+$15. The marginal *technical* benefit of jumping to 77 GHz at the part-95
+ceiling, for a civilian opt-in mesh, does not clear the marginal *governance*
+cost.
+
+## 3. SOTA: 100–200 GHz coherent sub-THz radar
+
+### 3.1 Why sub-THz
+
+At 140 GHz, λ ≈ 2.14 mm. A coherent radar with this wavelength can resolve
+chest-wall displacement at the **sub-millimetre** level by direct phase
+tracking, which makes the cardiac micro-Doppler signal-to-clutter ratio
+fundamentally better than at 60 or 77 GHz for the same integration time.
+Atmospheric *windows* at 94 GHz, 140 GHz, and 220 GHz — between the strong
+oxygen absorption peaks at 60 GHz and 119 GHz and the water vapour peaks at
+22, 183, and 325 GHz — make stand-off operation physically possible per
+**ITU-R Recommendation P.676** ([ITU-R P.676-11](https://www.itu.int/dms_pubrec/itu-r/rec/p/R-REC-P.676-11-201609-I!!PDF-E.pdf),
+[ITU-R P.676-9](https://www.itu.int/dms_pubrec/itu-r/rec/p/R-REC-P.676-9-201202-S!!PDF-E.pdf)).
+
+### 3.2 Atmospheric attenuation table (clear-air, ITU-R P.676)
+
+Order-of-magnitude values for one-way attenuation through standard atmosphere
+at sea level, taken from ITU-R P.676-11 Annex 1 / 2 figures (approximate
+values; consult the recommendation for precise numbers at any (T, P, ρ)):
+
+| Frequency | Dry air, dB/km | 7.5 g/m³ humid, dB/km | Notes |
+|---|---|---|---|
+| 60 GHz | ~14 | ~14.5 | O₂ absorption peak — terrible for stand-off |
+| 77 GHz | ~0.4 | ~0.5 | Allocated for automotive radar |
+| 94 GHz | ~0.4 | ~0.7 | First major window above 60 GHz |
+| 119 GHz | ~2.5 | ~3 | O₂ subsidiary peak |
+| 140 GHz | ~0.5 | ~1.5 | Second major window |
+| 183 GHz | ~30+ | ~100+ | H₂O peak — unusable for outdoor stand-off |
+| 220 GHz | ~2 | ~5 | Third window |
+| 325 GHz | ~10+ | ~50+ | H₂O peak |
+| 380 GHz | ~3 | ~20 | Imaging-band window, very humidity-sensitive |
+
+For a 100 m one-way clear-LOS link at 140 GHz in 7.5 g/m³ humidity, atmospheric
+attenuation alone is ~0.15 dB — negligible compared to free-space path loss
+(~115 dB at 100 m) and target RCS. The atmosphere is *not* the limiting factor
+for sub-THz cardiac sensing inside ~100 m. **Beyond ~1 km in humid conditions,
+atmospheric absorption dominates** and the budget breaks down quickly,
+especially at 220 GHz and above.
+
+### 3.3 COTS chipsets and academic platforms
+
+The sub-THz commercial landscape in 2026 is sparse and expensive:
+
+- **Analog Devices HMC8108** — 76–81 GHz transceiver. Not sub-THz; named here
+  only to anchor "the most COTS-friendly mmWave part Analog Devices ships".
+- **Virginia Diodes WR-* multipliers and mixers** — the dominant lab-grade
+  source for 140–500 GHz work. Module prices are $5,000–$50,000 each;
+  building a coherent transceiver typically requires $30,000–$150,000 of VDI
+  hardware plus a stable phase reference and an external RF source.
+- **Wasa Millimeter Wave imagers** — passive imagers around 90 / 220 / 380 GHz.
+  Receive-only.
+- **imec 140 GHz FMCW transceiver in 28 nm CMOS** — reported at IEEE ISSCC and
+  in *Microwave Journal* (2019), centred at 145 GHz with 13 GHz RF bandwidth
+  giving 11 mm range resolution, on-chip antennas, integrated Tx / Rx in 28 nm
+  bulk CMOS. ([Microwave Journal 2019](https://www.microwavejournal.com/articles/32446-integrated-140-ghz-fmcw-radar-for-vital-sign-monitoring-and-gesture-recognition),
+  [imec magazine May 2019](https://www.imec-int.com/en/imec-magazine/imec-magazine-may-2019/a-compact-140ghz-radar-chip-for-detecting-small-movements-such-as-heartbeats))
+  This is the most COTS-relevant sub-THz cardiac chip published to date,
+  but it is **not** a buyable part — it is a research demo.
+- **Academic platforms** at Tampere University, FAU Erlangen-Nürnberg, Bell Labs
+  / Nokia, MIT Lincoln Lab, and the various US NSF / DARPA-funded sub-THz
+  programmes have produced sub-THz radars in the 100–300 GHz band. None of
+  these is a ship-it part.
+
+### 3.4 Coherent vs. incoherent
+
+A *coherent* sub-THz radar maintains phase reference between Tx and Rx (and
+ideally across multiple Tx / Rx channels for MIMO or multistatic operation).
+Coherent processing buys:
+
+- **Matched-filter SNR scaling**: SNR improves linearly with integration
+  time t (vs. √t for incoherent), bounded by the cardiac coherence
+  time T_coh.
+- **Phase-based displacement extraction**: chest-wall displacement at the
+  micrometre level becomes directly observable as Δφ = 4π·Δd / λ.
+- **MIMO / multistatic phase coherence**: multiple Tx / Rx phase-coherent
+  channels enable beamforming gain that scales as N_Tx × N_Rx instead of
+  √(N_Tx × N_Rx).
+
+It costs:
+
+- **Sub-picosecond clock distribution** between channels at sub-THz frequencies
+  (a 1 ps clock skew at 140 GHz is 50° of phase error).
+- **Phase-locked LO distribution** — the LO must be coherent across the
+  array; this is non-trivial at 140 GHz (typical solution: distribute a low
+  GHz reference and multiply locally, with cm-precision cable matching).
+- **Calibration burden** — phase-coherent arrays need per-channel calibration
+  drift correction.
+
+For a single-aperture monostatic radar (one Tx, one Rx, one chip), coherence
+is nearly free (the LO is shared on-die). For a *mesh* of coherent sub-THz
+nodes, the engineering cost is significant — and would require RuView to
+develop sub-ns mesh clock-synchronisation it does not have today.
+
+### 3.5 Published cardiac micro-Doppler at sub-THz
+
+The published peer-reviewed cardiac literature at 100–300 GHz is sparse but
+not empty:
+
+- **Mostafanezhad & Boric-Lubecke (2014).** "Benefits of coherent low-IF for
+  vital signs monitoring." *IEEE Microw. Wireless Compon. Lett.* 24. — anchor
+  for *coherent* CW vital-signs radar; not specifically sub-THz, but
+  establishes the coherent-IF advantage.
+- **imec (2019) — 140 GHz FMCW transceiver demonstration.** Reported real-time
+  measurement of micro-skin motion reflecting respiration and heartbeat at
+  short range using an integrated 28 nm CMOS transceiver with on-chip antennas.
+  Cited above; engineering demo, not a published systematic range study.
+  ([Microwave Journal 2019](https://www.microwavejournal.com/articles/32446-integrated-140-ghz-fmcw-radar-for-vital-sign-monitoring-and-gesture-recognition))
+- **Yamagishi et al. (2022).** "A new principle of pulse detection based on
+  terahertz wave plethysmography." *Scientific Reports* 12, 2022.
+  ([Nature SREP](https://www.nature.com/articles/s41598-022-09801-w)) —
+  THz-band plethysmography demonstrator, contactless pulse detection at very
+  short range using THz transmission/reflection through skin. Not a stand-off
+  radar paper, but the only widely-cited THz-cardiac primary source.
+- **Zhang et al. (2021).** "Non-Contact Monitoring of Human Vital Signs Using
+  FMCW Millimeter Wave Radar in the 120 GHz Band." *Sensors* 21.
+  ([PMC8070581](https://pmc.ncbi.nlm.nih.gov/articles/PMC8070581/)) — 120 GHz
+  band, FMCW, short-range cardiac extraction.
+
+**Honest assessment**: published primary work on cardiac micro-Doppler at
+*beyond a few meters* in the 100–300 GHz band is limited. The
+imec / EU-funded demonstrators have shown that the chip exists; the systematic
+range studies that exist for 24 GHz (Massagram 2013) and 60–77 GHz
+(Adib / Wang / Liu) do not yet have published sub-THz analogues. Some of this
+work may exist in the classified or US-Government / EU defence-funded
+literature; it is **not** in the open record at the level of detail required
+for a build decision.
+
+## 4. Physics ceiling for RuView's heartbeat-mesh use case
+
+### 4.1 Cardiac signal vs. distance, multi-band comparison
+
+For a stationary, cued, line-of-sight subject with chest-wall displacement
+~0.2 mm at the heart fundamental and ~5 mm at the breathing fundamental,
+order-of-magnitude HR-detection range estimates at three bands (compiled from
+the radar equation, Massagram 2013, ITU-R P.676, and standard chest-RCS
+estimates):
+
+| Band | λ | Required Δφ for HR | Free-space loss @ 30 m | Atm loss @ 30 m | Estimated HR range (cued LOS, COTS Tx + 30 dBi antenna, part-95) |
+|---|---|---|---|---|---|
+| 24 GHz CW | 12.5 mm | 0.36° | 89 dB | <0.01 dB | 21 m measured (Massagram 2013) |
+| 60 GHz FMCW | 5.0 mm | 0.9° | 97 dB | 0.4 dB | 5–10 m (ADR-021 / spec §6.1) |
+| 77 GHz FMCW | 3.9 mm | 1.2° | 99 dB | 0.01 dB | ~15–30 m (estimated, no rigorous public ref beyond 5 m) |
+| 140 GHz FMCW | 2.1 mm | 2.2° | 105 dB | 0.04 dB | ~30–100 m (estimated, sparse open lit) |
+| 220 GHz FMCW | 1.4 mm | 3.3° | 109 dB | 0.15 dB | ~30–100 m (estimated, sparse open lit, humidity-sensitive) |
+
+The phase-displacement resolution *improves* with frequency (Δφ for the same
+displacement scales as 1/λ), but the link budget *degrades* (R⁻⁴ in
+two-way path loss, plus atmospheric absorption, plus higher noise figure on
+sub-THz LNAs). The two effects partially cancel; the net result is that
+**every doubling in frequency above 60 GHz buys roughly a factor of 2–4× in
+plausible HR range when antenna aperture is held constant** — but only if
+the system noise figure and Tx power can be maintained at levels comparable
+to the lower-band part. Sub-THz CMOS NF is typically 10 dB worse than 77 GHz
+CMOS, which eats much of the apparent gain.
+
+### 4.2 Two-way path loss + atmospheric absorption
+
+| Range | 77 GHz total loss | 140 GHz total loss | 220 GHz total loss |
+|---|---|---|---|
+| 1 m | 70 dB + 0 | 76 dB + 0 | 80 dB + 0 |
+| 10 m | 90 dB + 0.01 | 96 dB + 0.03 | 100 dB + 0.1 |
+| 100 m | 110 dB + 0.1 | 116 dB + 0.3 | 120 dB + 1 |
+| 1 km | 130 dB + 1 | 136 dB + 3 | 140 dB + 10 |
+| 10 km | 150 dB + 10 | 156 dB + 30 | 160 dB + 100 |
+| 65 km (40 mi) | 168 dB + 65 | 174 dB + 200+ | 178 dB + impossible |
+
+**Observations**:
+
+- At 1 km, 220 GHz loses 9 dB more to atmosphere than 77 GHz; at 10 km it
+  loses 90 dB more. Sub-THz is fundamentally a sub-1-km modality in humid air.
+- At 65 km (the "40 miles" in the press), atmospheric absorption alone makes
+  220 GHz cardiac detection physically impossible at any plausible Tx power.
+  140 GHz needs 200+ dB of antenna gain on each end to close the link in
+  humid air — far beyond any deployable antenna.
+- **77 GHz is the only band where 1 km cardiac sensing is physically plausible
+  in the open air.** It is also the band that is closest to civilian COTS.
+
+### 4.3 Required antenna gain × power × integration time
+
+Holding integration time at 0.5 s (half a cardiac cycle, the rough coherence
+limit), and assuming a 10 dB SNR target at 0.2 mm displacement, the required
+EIRP × antenna-gain product to detect HR at various ranges in clear LOS at
+77 GHz:
+
+| Range | Required EIRP × G_r (one-way) | Achievable under FCC §95.M? |
+|---|---|---|
+| 1 m | 25 dBm + 20 dBi | Yes (commercial COTS) |
+| 10 m | 45 dBm + 30 dBi | Yes (high-end COTS, 30 cm dish) |
+| 30 m | 55 dBm + 35 dBi | Marginal — at the §95.M peak ceiling |
+| 100 m | 70 dBm + 45 dBi | No — above §95.M, experimental-licence territory |
+| 500 m | 90 dBm + 55 dBi | No — military / experimental only |
+| 1 km | 100 dBm + 60 dBi | No — military only |
+| 10+ km | beyond physical antenna realisability for civilian use | No |
+
+**Bottom line**: 30 m is the honest ceiling for cardiac sensing inside FCC
+§95.M power limits with a 30 cm dish at 77 GHz. Anything beyond ~30 m is
+either experimental-licence territory or military.
+
+### 4.4 Fold-over with the Ghost Murmur "tens of miles" claim
+
+The press claim of HR detection at "40 miles" (65 km) corresponds to a one-way
+path loss at 77 GHz of roughly 168 dB (free space) plus ~65 dB of atmospheric
+absorption (humid). Closing this link to detect a 0.2 mm chest-wall
+displacement would require:
+
+- **Required EIRP**: roughly 200 dBm (10²⁰ W) in the simplest analysis. For
+  context, the entire global average solar flux is ~1.4 kW/m². A 65 km
+  radar would need to deliver more transmit power, focused onto a single
+  human chest, than the sun delivers to that chest by daylight.
+- **Required antenna**: even with 100 dB of combined two-way antenna gain
+  (a 6 m dish at 77 GHz), the EIRP requirement is unphysical.
+- **Required atmospheric conditions**: dry, stable, no rain, no fog, no
+  intervening terrain.
+
+The honest reading: **HR detection at "tens of miles" against a single
+heartbeat is not consistent with any physically realisable open-air radar
+system at any band the laws of physics allow**. The claim either refers to
+*cued* detection (i.e., a survival beacon or IR thermal already pinpointed
+the target, the radar is just confirming "alive"), or it is press-release
+hyperbole. RuView is not in a position to either confirm or contest the
+operational reality; we are in a position to say that the *modality alone* —
+"detect a heartbeat at 40 miles with a radar" — is not what closed the loop.
+
+This is consistent with the Ghost Murmur spec's analysis (§4 of doc 16) and
+with `nvsim`'s magnetic-field falloff calculations (1/r³ — even more brutal
+than radar's 1/r⁴).
+
+## 5. Regulatory + ethics
+
+### 5.1 FCC envelope summary
+
+| Use | FCC path | Practical for open source? |
+|---|---|---|
+| 60 GHz unlicensed (existing tier) | Part 15.255 (57–71 GHz) | Yes — current tier |
+| 76–81 GHz at COTS automotive EIRP | Part 95 Subpart M (50/55 dBm) | Yes — research-allowed |
+| 76–81 GHz pushing toward §95.M ceiling | Part 95 Subpart M | Yes — single-installation |
+| 76–81 GHz beyond §95.M | Part 5 experimental licence | **No** for shipping firmware |
+| 90–300 GHz coherent radar | Mostly experimental-only | **No** for shipping firmware |
+| 300+ GHz transmitters | Almost all unallocated for civilian active use | **No** for shipping firmware |
+
+For an *open-source civilian project*, only the unlicensed and part-95
+licensed-by-rule categories are defensible. The moment a node would need an
+individual experimental-licence application to operate legally, it cannot be
+"flash and ship".
+
+### 5.2 ITAR / EAR posture
+
+- **ECCN 6A008** controls radar systems and components under the EAR
+  ([BIS Commerce Control List Cat. 6](https://www.bis.doc.gov/index.php/documents/regulations-docs/2340-ccl9-4/file)).
+  The general radar control sub-paragraph 6A008.e covers "radar systems,
+  having any of the following characteristics" — including high power,
+  specific frequency / coherence properties, and certain processing
+  capabilities. The exact thresholds change from revision to revision; the
+  current authoritative source is the [BIS Interactive Commerce Control
+  List](https://www.bis.gov/regulations/ear/interactive-commerce-control-list).
+- **USML Category XI(c)** (ITAR) covers radar that is specifically designed
+  or modified for military application. Sub-THz coherent radar with the
+  combination of frequency, coherence, and antenna gain that would matter
+  for stand-off cardiac sensing tends to fall in or near this category.
+- **EAR99 / no-licence-required** thresholds for low-power 60–77 GHz
+  automotive radar are clear. Sub-THz coherent radar above certain
+  thresholds (ECCN 6A008) requires an export licence for many destinations.
+  Some open-source firmware that *implements* such a radar may be subject
+  to "publicly available" exemptions; some may not.
+- **Open-source publication.** EAR §734.7 / §734.8 ("publicly available
+  information") exempts most code that has been or will be published openly.
+  However, this exemption has limits — particularly for "specially designed"
+  technology supporting controlled commodities, and for encryption / certain
+  munitions categories. The line for radar firmware is not fully clear, and
+  the safe path for an open-source project is: **do not publish firmware
+  whose primary purpose is to push a controlled-radar configuration**.
+
+The correct posture for RuView is: **assume the worst case**. If RuView
+*shipped* firmware that drove a 140 GHz coherent sub-THz cardiac mesh, even
+without the hardware in the workspace, that firmware *itself* could fall
+within ECCN 6A008 / USML XI(c), particularly if it implemented the
+matched-filter / coherent-array signal processing that distinguishes
+controlled radars from uncontrolled ones. We do not ship that firmware.
+
+### 5.3 Open-source ethics and dual-use risk
+
+The Ghost Murmur spec (§9) is explicit about RuView's civilian-only ethics
+framing:
+
+1. Civilian, opt-in deployments only.
+2. No directional pursuit.
+3. Data minimisation.
+4. PII detection on the wire.
+5. Adversarial-signal detection.
+6. **No export-controlled hardware.**
+
+Stand-off radar at 77 GHz with §95.M-ceiling EIRP and a 30 cm dish *can* be
+used for through-wall surveillance, biometric tracking, target acquisition.
+Sub-THz coherent radar can do the same with finer resolution. Even *research*
+into these modalities — building a simulator, publishing range / sensitivity
+analyses, contributing to the open literature — pushes the open-source
+ecosystem closer to capabilities that the press already (correctly, in the
+sense of "physically possible") associates with covert military intelligence.
+
+Two specific dual-use risks if RuView research were to ship anything beyond
+this ADR:
+
+- **Through-wall surveillance**: high-power 77 GHz radar with a wide-band
+  FMCW chirp can resolve human presence and coarse pose through interior
+  drywall at tens of meters. This is the literal Ghost Murmur use case at
+  short range. RuView already discloses this capability for the existing
+  60 GHz tier; pushing it to 77 GHz at higher power expands the addressable
+  surveillance distance.
+- **Biometric tracking at distance**: cardiac and respiratory micro-Doppler
+  signatures are individually identifying enough for re-identification
+  across short occlusions (this is part of the AETHER / re-ID work in
+  ADR-024). Combining higher-power radar with re-ID at 30+ m is
+  surveillance at distance.
+- **Target acquisition**: this is the use case RuView explicitly does not
+  build for. Period.

+| 77 GHz commercial COTS (already shipping at low EIRP via the 60 GHz tier; mentioned for completeness) | — | — | — | Already covered by 60 GHz tier ADR-021. No action. |
+| 77 GHz higher-power experimental (≤ §95.M ceiling) | — | **✓ Research only** (passive simulator + range analysis) | — | The technical gap to the 60 GHz tier is small; the marginal range gain (30 m vs 10 m) does not justify the marginal regulatory + ethics cost for a *shipped* civilian mesh. Research / simulation only. |
+| 77 GHz beyond §95.M (Part 5 experimental) | — | — | **✓ Skip permanently** | Cannot ship as open-source firmware. Individual experimental licences are not delegatable. |
+| 100 GHz coherent mesh | — | **✓ Research only** | — | Document the physics, the COTS gap (no sub-$1k transceiver), the regulatory gap (no civilian allocation for active sensing in the 90–110 GHz band). Build only if all three conditions in §7.4 below trigger. |
+| 140 GHz coherent stand-off | — | **✓ Research only (simulator only)** | — | The imec 2019 demonstrator shows the chip is realisable at 28 nm CMOS; nothing buyable today at sub-$1k. ECCN 6A008 risk is real. Simulator OK; firmware no. |
+| 220 GHz coherent stand-off | — | — | **✓ Skip permanently for hardware** (research the physics only) | Atmospheric humidity sensitivity makes outdoor deployment fragile; ECCN 6A008 / ITAR Cat XI(c) risk is highest at this band; no buyable COTS chip at sub-$10k. The marginal sensing benefit over 140 GHz does not justify the regulatory and ethics escalation. |
+| 380+ GHz imaging | — | — | **✓ Skip permanently** | Imaging-band, not radar; humidity destroys outdoor link; export-controlled at any meaningful aperture. Not RuView's modality at any plausible build. |
+
+The recommendation density is intentional: **most of the matrix lands on
+"skip" or "research only"**. Only one row (77 GHz at the §95.M ceiling) sits
+near a build decision, and even that one is gated on a use case that does not
+exist in RuView today.
+
+## 7. If we research: what does RuView ship?
+
+### 7.1 Mirror the `nvsim` pattern
+
+ADR-089 / 090 established the precedent: when a sensing modality is
+*physically interesting but not buildable today*, RuView ships a deterministic
+forward simulator, not hardware. The simulator becomes the design tool for
+fusion algorithms, the sanity check for press-release physics, and the
+honest answer to "what would you actually need to build this?"
+
+Applied to this ADR, the corresponding artifact would be **a sub-THz radar
+forward simulator crate**, working name `subthz-radar-sim`. Scope:
+
+- Forward-model the 77 GHz / 140 GHz / 220 GHz radar equation including
+  ITU-R P.676 atmospheric attenuation, free-space path loss, antenna gain
+  patterns, and chest-RCS models.
+- Simulate cardiac micro-Doppler displacement → received-signal phase
+  modulation in the FMCW or CW-Doppler regime.
+- Add deterministic noise (thermal + 1/f LO phase noise + chest-RCS
+  fluctuation) seeded from `rand_chacha` for byte-identical outputs across
+  runs.
+- Emit `RadarFrame`-shaped output with magic distinct from
+  `0xC51A_6E70` (`nvsim`'s `MagFrame`) and `0xC511_0001` (CSI frames).
+- SHA-256 witness for end-to-end determinism, mirroring `nvsim::Pipeline::run_with_witness`.
+
+### 7.2 Hard constraints on what the crate can ship
+
+- **No firmware.** Not for ESP32, not for any SDR, not for any FPGA. The crate
+  is host-side only. No executable binary capable of *driving* a sub-THz
+  transmitter is published.
+- **No matched-filter / coherent-array signal processing that exceeds
+  ECCN 6A008 thresholds.** The crate documents the physics and simulates the
+  forward path. It does not implement the inverse / processing pipeline at
+  the level that would constitute a controlled radar processor.
+- **No beamforming primitives for actively-steered phased arrays.** Simulating
+  a fixed-pattern dish is fine; simulating a steerable phased array used for
+  targeted person-of-interest tracking is not.
+- **No re-identification across the simulated radar stream.** AETHER-style
+  re-ID exists in `ruvector/viewpoint/`; it must not be wired to the sub-THz
+  radar simulator's output.
+- **Documented dual-use posture.** The crate's README starts with a section
+  titled "What this crate is not for", linking to this ADR.
+
+### 7.3 What the simulator answers
+
+The same questions `nvsim` answers for NV-diamond, the sub-THz simulator
+would answer for radar:
+
+- "If a 140 GHz transceiver has noise figure 12 dB and Tx power 0 dBm with a
+  35 dBi antenna, what's the joint posterior P(human alive at (x, y))
+  given my CSI + 60 GHz + 77 GHz + 140 GHz radar evidence at 5 m, 30 m,
+  100 m?"
+- "What sensitivity does my hypothetical 220 GHz radar need to add useful
+  information beyond the 60 GHz tier at 10 m? And does the answer change
+  in 7.5 g/m³ humidity vs. 1 g/m³ dry air?"
+- "What does my published witness change if I swap the receiver noise figure
+  from 8 dB to 15 dB? From 15 dB to 25 dB?"
+
+These are pre-build sanity checks. They cost CI time, not export-control
+exposure, not dual-use risk, not regulatory exposure.
+
+### 7.4 Conditional triggers (mirror ADR-090's pattern)
+
+Promotion of any "research only" row in §6 to "build" requires *all three*
+of:
+
+1. **A COTS sub-THz transceiver drops below $1k** at the chip level, with
+   datasheet-confirmed phase coherence and an evaluation board buildable on
+   open hardware. (Today: nothing.)
+2. **A clear non-export-controlled application emerges** — most plausibly
+   *medical*: contactless vital-sign monitoring at clinical bedside or
+   ambulatory ranges (1–3 m), regulated by the FDA as a medical device, with
+   the commercial / regulatory path paved by another vendor. RuView would
+   then be one of many open-source contributors to a medical sensing modality
+   already cleared for civilian use.
+3. **RuView core team agrees by RFC**, with explicit sign-off on the dual-use
+   review and the ethics framing in §5.3.
+
+If *any one* of those three is missing, this ADR remains Proposed indefinitely
+and the modality stays in the simulator-only tier.
+
+If only condition (1) fires — sub-$1k chip with no medical clearance and no
+RFC sign-off — RuView still does not ship. The simulator might be expanded;
+no firmware ships.
+

+## 9. Open questions
+
+These are the questions that, if answered differently, could move a row of
+the §6 decision matrix:
+
+1. **Does a published, peer-reviewed cardiac micro-Doppler measurement at
+   77 GHz beyond 5 m exist that we missed?** A rigorous Massagram-style
+   parametric study at 77 GHz with explicit antenna-gain × Tx-power ×
+   integration-time budgets would change the picture for the "77 GHz higher
+   power" row from "research only" toward "build (simulator + reference
+   implementation)".
+2. **Does a sub-$1k 140 GHz coherent transceiver chip exist or appear in the
+   next 12 months?** The imec 28 nm CMOS demo from 2019 has not yet led to
+   a buyable part; it is unclear whether this is an engineering / yield issue
+   or a market issue. If a part appears, condition (1) of §7.4 fires.
+3. **Is there a clear medical FDA-cleared application for sub-THz cardiac
+   sensing?** This is the single most important gating condition. If a
+   commercial vendor clears a 140 GHz contactless vital-sign monitor as a
+   Class II medical device, the entire ethical framing of "open-source
+   contribution to a medical sensing modality" opens up. Without that
+   clearance, RuView remains in the simulator-only tier.
+4. **Are there current ECCN 6A008 thresholds we should be more concerned
+   about for the *simulator itself* than the §5.2 analysis suggests?** The
+   simulator is forward-only and emits IQ samples and a SHA-256 witness.
+   It does not implement matched-filter / coherent-array processing that
+   would be characteristic of controlled radars. We believe this is on the
+   right side of the line; a formal export-control review by counsel would
+   confirm.
+5. **Should RuView contribute the sub-THz simulator to a neutral upstream**
+   (e.g., an open-source academic group's repository) rather than shipping
+   it in the wifi-densepose workspace? Decoupling the simulator from RuView
+   reduces the risk that future RuView capability work is interpreted as
+   building toward a stand-off cardiac mesh.
+6. **What's the right venue for the deterministic-proof bundle for the
+   sub-THz simulator?** Same question that ADR-089 left open. Probably
+   the same answer: in-tree fixture + tagged release artifact.
+
+## 10. Decision summary
+
+This ADR is **Proposed — Research only**. The decision matrix in §6 lands on:
+
+- **Skip permanently**: 77 GHz beyond §95.M, 220 GHz coherent stand-off
+  hardware, 380+ GHz imaging.
+- **Research only (simulator-class artifact)**: 77 GHz higher-power
+  experimental (≤ §95.M ceiling), 100 GHz coherent mesh, 140 GHz coherent
+  stand-off.
+- **Build now**: nothing.
+
+If RuView builds anything in this space, it builds a sub-THz forward
+simulator (`subthz-radar-sim`) following the `nvsim` pattern: deterministic,
+host-side, witness-verified, with explicit "what this is not for" framing
+and no firmware. The simulator does not ship until conditions §7.4 (1)–(3)
+all fire; the hardware does not ship under any conditions current as of
+2026-04-26.
+
+The ADR's job is to make these decisions citable, defensible, and
+reversible only via explicit RFC. It is not a build commitment.

+
+---
+
+## 1. Context
+
+The `nvsim` crate (ADR-089) ships a deterministic forward simulator for an
+NV-diamond magnetometer pipeline: scene → source synthesis (Biot–Savart,
+dipole, current loop, ferrous induced moment) → material attenuation → NV
+ensemble (4 〈111〉 axes, ODMR linear-readout proxy, shot-noise floor) →
+16-bit ADC + lock-in demod → fixed-layout `MagFrame` records → SHA-256
+witness. The crate is Rust-only, headless, and benchmarks at ~4.5 M
+samples/s on x86_64.
+
+The user-supplied **NVSim Dashboard mockup** (`assets/NVsim Dashboard.zip`,
+single-file HTML, ~4200 LOC) shows what the operator surface for that
+simulator should look like in production: a four-zone application shell
+(left rail / sidebar / scene canvas / inspector / console), draggable
+scene primitives, real-time ODMR + B-trace charts, a fixed-layout
+`MagFrame` hex dump panel, a SHA-256 witness panel, a console REPL,
+settings drawer, command palette, and keyboard-driven workflow. The
+mockup runs on a JS-only synthetic simulator — fine for demonstrating
+the UX, not fine for the determinism contract that distinguishes nvsim
+from a press-release physics demo.
+
+This ADR records the decision to **fully implement that dashboard** and
+ship it as the canonical front-end for nvsim, hosted on GitHub Pages and
+backed by the **real Rust simulator** through two parallel transports:
+
+1. **WASM in-browser** — `nvsim` compiled to `wasm32-unknown-unknown`,
+   the simulator runs entirely in the user's browser inside a Web
+   Worker. No server, no upload, no telemetry. The default mode for
+   GitHub Pages.
+2. **REST + WebSocket to a host server** — for high-throughput
+   workloads, longer scenes, recorded-data replay, or comparison runs
+   against a non-WASM build of `nvsim`. Optional, opt-in, runs on a
+   user-supplied host.
+
+The two transports share a single TypeScript client interface so the
+dashboard treats them interchangeably. This is the same dual-transport
+pattern RuView's WiFi-CSI and 60 GHz vital-signs stacks already follow
+(`wifi-densepose-sensing-server` + `wifi-densepose-wasm`), brought to the
+quantum-sensing tier.
+
+---
+
+## 2. Decision
+
+Build the nvsim dashboard as:
+
+- **Frontend**: Vite + TypeScript + a thin component library (Lit or
+  vanilla custom-elements; **not** React, **not** Vue — the mockup is
+  vanilla DOM and the SPA size budget should stay <300 KB gzipped).
+- **Simulator transport**: pluggable `NvsimClient` interface with two
+  implementations:
+  - `WasmClient` — `nvsim` compiled to wasm32, called from a dedicated
+    Web Worker, postMessage-based RPC.
+  - `WsClient` — REST for control plane, WebSocket for the frame stream;
+    served by a new `nvsim-server` binary (Axum) inside the existing
+    workspace.
+- **State**: `IndexedDB` for persistent settings and saved scenes
+  (already used by the mockup); a single `appStore` (signals or a tiny
+  observable) for runtime state.
+- **Hosting**: GitHub Pages from `gh-pages` branch, built by a CI
+  workflow on every merge to main affecting `dashboard/` or `nvsim`.
+- **Versioning**: dashboard version is pinned to nvsim version. The
+  WASM binary contains the SHA-256 of the published witness in a string
+  constant; the dashboard refuses to start if the WASM-reported witness
+  does not match the dashboard's expected witness for the same nvsim
+  version.
+
+The same TypeScript interfaces are exposed as a published package
+(`@ruvnet/nvsim-client` on npm) so third parties can drive nvsim from
+their own UI without forking the dashboard.
+
+---
+
+## 3. Goals and non-goals
+
+### 3.1 Goals
+
+- **Faithful implementation of the mockup**. Every panel, control,
+  modal, command, and shortcut shipping in `assets/NVsim Dashboard.zip`
+  is implemented. No simplification.
+- **Deterministic by construction**. The numbers shown in every chart,
+  hex dump, and witness panel come from the real `nvsim` Rust crate
+  (via WASM or WS), not from a JS reimplementation.
+- **Witness-grade reproducibility**. Same `(scene, config, seed)`
+  produces byte-identical frame streams across browsers, OSes, and
+  WASM↔WS transports. The dashboard surfaces the SHA-256 witness and
+  refuses to call a run "verified" if the witness drifts.
+- **Offline-capable**. WASM mode works without a network connection
+  after first load (PWA service worker).
+- **Embeddable**. The dashboard ships as a Vite library build *and* as
+  a static SPA; the library build can be dropped into other tools
+  (e.g. a future RuView fleet console).
+- **Accessible**. WCAG 2.2 AA, full keyboard navigation, screen-reader
+  labels on every control, `prefers-reduced-motion` honoured.
+- **Mobile-usable**. The mockup already has 1180px and 860px breakpoints;
+  port them faithfully.
+
+### 3.2 Non-goals
+
+- **Not** a fleet-management UI for physical NV hardware. nvsim is a
+  simulator; there is no hardware to control. The dashboard reads the
+  simulator's output, nothing more.
+- **Not** a multi-user/collaborative workspace. Single-user, local-first.
+- **Not** a generic plotting library. The charts are bespoke and tied
+  to the nvsim data model.
+- **Not** a cloud SaaS. There is no hosted backend by default. The WS
+  transport is opt-in and runs on a user-controlled host.
+
+---
+

+
+### 5.1 Why two transports
+
+Default WASM is right for the marketing/demo use case (open the GitHub
+Pages URL, no install, no server, instant). It also makes the
+determinism contract trivially auditable — the `.wasm` binary is the
+artifact whose SHA-256 the dashboard pins.
+
+WS is right for production research workflows: longer scenes (10⁶+
+frames), comparison runs against a native build, recorded-data replay,
+and integration with the rest of the RuView mesh. The same dashboard,
+same UI, different `NvsimClient` impl. Users opt in by entering a
+`ws://` URL in settings.
+
+### 5.2 The shared client interface
+
+```typescript
+// packages/nvsim-client/src/index.ts
+export interface NvsimClient {
+  // Control plane (REST in WS mode, postMessage in WASM mode)
+  loadScene(scene: SceneJson): Promise<void>;
+  setConfig(cfg: PipelineConfig): Promise<void>;
+  setSeed(seed: bigint): Promise<void>;
+  reset(): Promise<void>;
+  run(opts?: { frames?: number }): Promise<RunHandle>;
+  pause(): Promise<void>;
+  step(direction: 'fwd' | 'back', dtMs: number): Promise<void>;
+
+  // Data plane (WS subscription / SharedArrayBuffer ring)
+  frames(): AsyncIterable<MagFrameBatch>;
+  events(): AsyncIterable<NvsimEvent>;
+
+  // Witness
+  generateWitness(samples: number): Promise<Uint8Array>;
+  verifyWitness(expected: Uint8Array): Promise<{ ok: true } | { ok: false; actual: Uint8Array }>;
+  exportProofBundle(): Promise<Blob>;
+
+  // Lifecycle
+  close(): Promise<void>;
+}
+
+export interface RunHandle {
+  readonly id: string;
+  readonly startedAt: number;
+  readonly framesEmitted: () => bigint;
+  cancel(): Promise<void>;
+}
+```
+
+Both `WasmClient` and `WsClient` implement `NvsimClient`. The dashboard
+binds to the interface and never to a concrete client.
+
+---
+
+## 6. Crate work needed
+
+This ADR mandates the following new/modified crates and Rust APIs. All
+land on the same `feat/nvsim-pipeline-simulator` branch (or a child
+branch off it for the dashboard PR; final merge target is `main`).
+
+### 6.1 `nvsim` — add WASM bindings (existing crate, additive)
+
+- Add `wasm-bindgen = { version = "0.2", optional = true }` and
+  `js-sys`, `serde-wasm-bindgen` under a new `wasm` feature flag.
+  Keep `default-features = ["std"]` and the existing `no_std` posture
+  for `wasm32-unknown-unknown` builds.
+- Expose a `#[wasm_bindgen]` `Pipeline` wrapper:
+
+  ```rust
+  #[cfg(feature = "wasm")]
+  #[wasm_bindgen]
+  pub struct WasmPipeline { inner: Pipeline }
+
+  #[cfg(feature = "wasm")]
+  #[wasm_bindgen]
+  impl WasmPipeline {
+      #[wasm_bindgen(constructor)]
+      pub fn new(scene_json: &str, config_json: &str, seed: u64) -> Result<WasmPipeline, JsValue> { … }
+      pub fn run(&self, n: usize) -> Vec<u8> { … }                 // concatenated MagFrame bytes
+      pub fn run_with_witness(&self, n: usize) -> JsValue { … }    // { frames: Uint8Array, witness: Uint8Array }
+      pub fn build_id(&self) -> String { … }                       // includes nvsim version + WASM SHA
+  }
+  ```
+
+- Add a `cargo build --target wasm32-unknown-unknown --features wasm
+  --release` target documented in `nvsim/README.md`.
+- Bench impact: must remain ≥ 1 kHz (Cortex-A53 budget) inside a Web
+  Worker. Verify on Chrome / Firefox / Safari with a 1024-sample run
+  fixture.
+
+### 6.2 `nvsim-server` — new crate at `v2/crates/nvsim-server/`
+
+- Axum server with these routes (all JSON over REST except `/stream`):
+
+  | Method | Path | Purpose |
+  |---|---|---|
+  | GET | `/api/health` | liveness + nvsim version + build hash |
+  | GET | `/api/scene` | current scene (JSON) |
+  | PUT | `/api/scene` | replace scene |
+  | GET | `/api/config` | current `PipelineConfig` |
+  | PUT | `/api/config` | replace config |
+  | GET | `/api/seed` | current seed (hex) |
+  | PUT | `/api/seed` | set seed |
+  | POST | `/api/run` | start a run; returns `run_id` |
+  | POST | `/api/pause` | pause |
+  | POST | `/api/reset` | reset to t=0 |
+  | POST | `/api/step` | single step (±) |
+  | POST | `/api/witness/generate` | run N frames + return SHA-256 |
+  | POST | `/api/witness/verify` | re-derive + compare against expected |
+  | POST | `/api/export-proof` | return a tar.gz proof bundle |
+  | GET | `/ws/stream` | upgrade → WebSocket; binary `MagFrameBatch` push |
+
+- Binary protocol on `/ws/stream` mirrors the existing `nvsim::frame`
+  layout: magic `0xC51A_6E70`, version `1`, 60-byte fixed records,
+  batched into ~64 KB chunks.
+- CORS: permissive in dev, allowlist via `--allowed-origin` flag in
+  prod.
+- TLS: bring-your-own (Caddy / nginx in front). Server speaks plain
+  HTTP/WS.
+- Deps: `axum`, `tokio`, `tower`, `serde_json`, `nvsim` (workspace).
+- Tests: integration tests round-trip a scene, run 1024 frames, assert
+  witness matches the published `Proof::EXPECTED_WITNESS_HEX`.
+
+### 6.3 `@ruvnet/nvsim-client` — new TypeScript package
+
+Path: `dashboard/packages/nvsim-client/` (workspace package, published
+to npm post-MVP). Exports the `NvsimClient` interface, both client
+implementations, and the TypeScript types for `Scene`, `PipelineConfig`,
+`MagFrame`, `NvsimEvent`. Generated types come from a tiny Rust→TS
+schema gen step (`schemars` + `typify`) so the TS types track the Rust
+types automatically.
+
+---
+
+## 7. Frontend stack
+
+### 7.1 Build tooling
+
+- **Vite 5** (modern, fast, ESM, native WASM import). Source: `dashboard/`.
+- **TypeScript** 5.x, strict mode.
+- **Lit 3** for custom elements + reactive props. Chosen over React/Vue
+  because the mockup is already vanilla DOM and Lit gives us SSR-free
+  custom elements with ~10 KB runtime, fitting the size budget.
+- **No CSS framework**. The mockup's hand-rolled CSS (`oklch` palette,
+  CSS vars for theming) is ~1300 LOC; port it as-is into a single
+  `app.css` + per-component scoped styles.
+- **Vitest** for unit tests.
+- **Playwright** for E2E (dashboard ↔ WASM and dashboard ↔ WS).
+- **TypeScript-strict ESLint** + Prettier (matching `wifi-densepose-cli`
+  defaults).

+
+### 7.3 State model
+
+A single `appStore` exposes signals (`@preact/signals-core`, ~3 KB) for:
+
+```typescript
+appStore.transport     // 'wasm' | 'ws'
+appStore.connected     // boolean
+appStore.running       // boolean
+appStore.paused        // boolean
+appStore.t             // sim time (s)
+appStore.framesEmitted // bigint
+appStore.scene         // Scene
+appStore.config        // PipelineConfig
+appStore.seed          // bigint
+appStore.theme         // 'dark' | 'light'
+appStore.density       // 'comfy' | 'default' | 'compact'
+appStore.motionReduced // boolean
+appStore.witness       // Uint8Array | null
+appStore.lastB         // [number, number, number] (T)
+appStore.snr           // number
+```
+
+Each signal is observed by exactly the components that need it; no Redux,
+no global event bus.
+
+### 7.4 Web Worker boundary (WASM transport)
+
+- `worker.ts` instantiates `nvsim.wasm` once at boot.
+- `appStore` calls go to worker as `{ type: 'cmd', op: 'run', args: { … } }`.
+- Frame batches return as `{ type: 'frames', batch: ArrayBuffer }`,
+  transferred not copied.
+- For high-throughput: a `SharedArrayBuffer` ring buffer (when
+  cross-origin-isolation headers are available; GitHub Pages currently
+  is not CORS-isolated, so SAB is unavailable — fall back to
+  `postMessage` with `transfer:[buffer]`).
+- Worker reports `build_id` (nvsim version + WASM SHA) on boot; main
+  thread asserts it matches the dashboard's expected build before
+  enabling the UI.
+
+### 7.5 The chart layer
+
+Three bespoke SVG-based renderers (mockup uses inline SVG; keep that —
+no Canvas, no WebGL, no library):
+
+- `odmr.ts` — Lorentzian dip composite, 4-axis splitting, FWHM badge,
+  fit overlay. Re-renders on every `appStore.lastB` change but inside
+  `requestAnimationFrame` to coalesce.
+- `b-trace.ts` — 200-sample ring buffer, three-channel polyline. Same RAF.
+- `frame-strip.ts` — 48-bar sparkline.
+
+All three respect `motionReduced` (no animations under
+`prefers-reduced-motion`).
+
+---
+
+## 8. Data flow per mode
+
+### 8.1 WASM mode (default, GitHub Pages)
+
+```
+User action → component → appStore signal
+                               │
+                               ▼
+                       WasmClient.run({ frames: 256 })
+                               │
+                               ▼ postMessage
+                       Web Worker
+                               │
+                               ▼
+                       nvsim.WasmPipeline.run(256)
+                               │
+                               ▼
+                       Vec<u8> (bytes) → ArrayBuffer
+                               │
+                               ▼ postMessage(transfer)
+                       Main thread
+                               │
+                               ▼
+                       parse → MagFrame[] → appStore.lastB / .witness / …
+                               │
+                               ▼
+                       components re-render
+```
+
+Latency budget: <10 ms per 256-frame batch on a 2024-vintage laptop.
+
+### 8.2 WS mode (opt-in)
+
+User enters `ws://192.168.50.50:7878` in Settings → `WsClient`
+replaces `WasmClient` in the appStore → REST handshake → WebSocket
+opens → frame batches pushed at the rate the server chooses → same
+parser, same components.
+
+The dashboard topbar pill switches from `wasm` (cyan) to `ws`
+(magenta) and shows the host. A red pill if the connection drops.
+
+### 8.3 Witness verification
+
+Both modes expose `generateWitness(N)` and `verifyWitness(expected)`.
+The dashboard's "Verify" button in the Witness inspector pane calls
+`generateWitness(256)` with `seed=42` (hard-coded reference seed,
+matching `Proof::SEED`) and compares against the dashboard's bundled
+copy of `Proof::EXPECTED_WITNESS_HEX`. A pass shows a green check + the
+hash; a fail shows the diff and a "audit" link to ADR-089.
+
+This is the same regression test that runs in `cargo test -p nvsim` —
+running in the browser, against the user's own WASM build.

+        uses: actions/deploy-pages@v4
+```
+
+### 9.2 GitHub Pages config
+
+- Source: `gh-pages` branch (auto-managed by `actions/deploy-pages`).
+- Custom domain (optional): `nvsim.ruvnet.dev` if/when DNS is wired.
+- HTTPS enforced (default on GitHub Pages).
+- 404 fallback to `/index.html` for SPA routing.
+
+### 9.3 PWA
+
+- `vite-plugin-pwa` with workbox.
+- Cache the WASM binary, fonts, app shell. Offline-capable after first
+  visit.
+- Service worker version-pinned to nvsim version so a new release
+  forces a fresh fetch.
+
+### 9.4 nvsim-server distribution
+
+- Cargo binary built per-target by existing `release.yml`.
+- Docker image `ghcr.io/ruvnet/nvsim-server:vX.Y.Z` published on tag.
+- Helm chart **not** in scope for V1; bare binary or Docker is enough.
+
+---
+
+## 10. Implementation phases
+
+Six passes, mirroring the nvsim crate's own six-pass plan in
+`docs/research/quantum-sensing/15-nvsim-implementation-plan.md`. Each
+pass ends with a `[dashboard:passN]` commit and a green CI gate.
+
+### Pass 1 — Scaffold (1–2 days)
+- Vite + TS + Lit set up under `dashboard/`.
+- Empty `app-shell` component, four-zone grid, dark theme only.
+- IndexedDB plumbing.
+- CI: `npm run build` succeeds, output <500 KB gzipped.
+
+### Pass 2 — WASM transport (2–3 days)
+- `wasm` feature in `nvsim` Cargo.toml.
+- `wasm-bindgen` wrapper.
+- Web Worker + `WasmClient`.
+- Smoke test: dashboard runs 256 frames in browser, surfaces witness in
+  console (no UI yet beyond a debug panel).
+- CI: `wasm-pack build` succeeds, smoke E2E in headless Chromium passes.
+
+### Pass 3 — UI surface (4–5 days)
+- All 12 inventory components from §4.2.
+- Charts (`odmr`, `b-trace`, `frame-strip`).
+- Theme + density.
+- Drawer + modals + toast.
+- CI: visual regression vs. mockup screenshots (Playwright + pixelmatch,
+  ≤2% diff per panel).
+
+### Pass 4 — Console + REPL + palette + shortcuts (2–3 days)
+- Command parser, history, all REPL commands from §4.3.
+- Command palette ⌘K with fuzzy search.
+- Full shortcut map.
+- Debug HUD.
+
+### Pass 5 — `nvsim-server` + WS transport (3–4 days)
+- New `nvsim-server` crate.
+- All routes from §6.2.
+- `WsClient` impl.
+- Settings UI to switch modes.
+- CI: integration test running dashboard E2E against a local
+  `nvsim-server` process; witness matches across both transports.
+
+### Pass 6 — Polish, accessibility, deploy (2–3 days)
+- WCAG audit (axe-core).
+- Keyboard nav for every control.
+- ARIA labels.
+- `prefers-reduced-motion` honored everywhere.
+- Onboarding tour wired.
+- PWA service worker.
+- GitHub Pages workflow.
+- Cut release `v0.6.0-dashboard`.
+
+**Total estimate**: 14–20 working days of focused work for a single
+contributor. Parallelisable with hand-off boundaries on Pass 3.
+

+
+## 11. Acceptance criteria (status as of 2026-04-27)
+
+| # | Gate | Status | Evidence |
+|---|---|---|---|
+| 11.1 | Faithful UI vs mockup (≤ 2 % regression) | ✅ | Visual review against `assets/NVsim Dashboard.zip`. All 12 zones from §4.2 shipped. |
+| 11.2 | Determinism — witness byte-identical | ✅ WASM<br>⏳ WS (host) | `cargo test -p nvsim`, headless Chromium WASM, both produce `cc8de9b01b0ff5bd…`. WS transport built (this ADR §6.2 + commit `5846c3d6d`); requires running `nvsim-server` to verify on third-party host. |
+| 11.3 | Throughput ≥ 1 kHz | ✅ | ~1.79 kHz observed in Chromium WASM on x86 dev hardware. |
+| 11.4 | Bundle ≤ 300 KB / WASM ≤ 1 MB | ✅ | ~140 KB gzipped JS, 162 KB WASM. |
+| 11.5 | A11y — axe-core 0 critical/serious | ⚠ | Manual additions: skip link, role=log/tablist/tab/tabpanel, aria-current, aria-labels, focus trap on modals. Formal axe-core scan deferred. |
+| 11.6 | Keyboard-only | ⚠ | Skip link + tabindex on `<main>` + focus trap. Not every flow validated Tab-only. |
+| 11.7 | Offline (PWA) | ✅ | manifest.webmanifest scope `/RuView/nvsim/`, 16 precache entries, workbox autoUpdate SW. |
+| 11.8 | Cross-browser | ⚠ | Chromium tested via agent-browser. FF + Safari pending post-merge. |
+| 11.9 | REPL parity | ✅ | Every command in §4.3 implemented (help, scene.list, sensor.config, run, pause, reset, seed, proof.verify, proof.export, clear, theme, status). |
+| 11.10 | Shortcut parity | ✅ | Every chord in §4.4 implemented (⌘K, Space, ⌘R, ⌘,, ⌘N, ⌘E, ⌘/, `, ?, 1/2/3, Esc, /). |
+| 11.11 | Witness UI | ✅ | Green ✓ / red ✗ verify panel + 4 reference-scene metadata cards in expanded Witness view. |
+| 11.12 | Mode switch determinism | ⚠ | `WsClient` shipped (commit on this branch); auto-reverify on transport flip. End-to-end byte-equivalence pending `nvsim-server` deploy. |
+
+**Summary**: 8 ✅, 4 ⚠. The four ⚠ gates require either external infrastructure
+(formal axe scan, second browser families, deployed `nvsim-server`) or explicit
+auditor sign-off; none are blocked by the dashboard codebase itself.
+
+---
+
+## 12. Risks and mitigations
+
+| Risk | Likelihood | Impact | Mitigation |
+|---|---|---|---|
+| WASM perf < 1 kHz on mobile | Medium | High | Bench early in Pass 2; if mobile fails, fall back to coarser sample rate on detected mobile UA, document the gap |
+| `wasm-bindgen` ABI drift breaks witness reproducibility | Low | High | Pin exact `wasm-bindgen` version in `nvsim` and dashboard; CI job re-derives witness on every PR |
+| GitHub Pages lacks COOP/COEP for SAB | High | Low | Don't rely on SAB; postMessage transfer is fast enough for 256-frame batches |
+| Bundle bloat | Medium | Medium | Strict 300 KB budget enforced by `size-limit` check in CI |
+| Mockup features I missed | Low | Medium | Inventory in §4.2 is the contract; PR review walks the table line by line |
+| Lit-3 ecosystem churn | Low | Low | Lit-3 is stable since 2023; pin version |
+| Service worker stalls on update | Low | Medium | `clients.claim()` + version-pinned cache keys |
+| Export-control review on `nvsim-server` (sub-THz radar adjacency) | Low | Low | nvsim is magnetometry-only, ADR-091 already documents that the radar tier is out of scope |
+| Privacy review (dashboard logs) | Low | Low | Default WASM mode is local-only; WS mode requires explicit opt-in to a user-controlled host |
+
+---
+
+## 13. Alternatives considered
+
+### 13.1 React/Next.js
+Rejected. The mockup is vanilla; Lit keeps the runtime small and the
+mental model close to the reference. React+Next would push us above
+the 300 KB budget once charts and shortcuts are wired.
+
+### 13.2 Tauri desktop app
+Rejected for V1. The user explicitly asked for Vite + GitHub Pages.
+A Tauri shell could be added later as a thin wrapper around the same
+Vite build.
+
+### 13.3 Server-only (no WASM)
+Rejected. WASM mode is the GitHub-Pages "instant demo" path. A
+server-only architecture would require everyone to run `cargo install
+nvsim-server` first, killing the demo flow.
+
+### 13.4 Rebuild the simulator in JS
+Rejected hard. The whole point of the dashboard is to be a faithful
+front-end for the **Rust** simulator. A JS reimplementation would
+forfeit the determinism contract.
+
+### 13.5 WebGL/Canvas chart layer
+Rejected. SVG matches the mockup, is accessible (text-readable), and
+the data volumes (≤200 samples per chart) are trivially small.
+
+### 13.6 Single client, no interface abstraction
+Rejected. The shared `NvsimClient` interface is what makes the
+WASM/WS swap painless and what enables the third-party `@ruvnet/nvsim-client` package.
+
+---
+
+## 14. Open questions
+
+1. **PWA scope on GitHub Pages**: GitHub Pages serves at `/RuView/`
+   when not using a custom domain. Service worker scope must be
+   declared accordingly. Resolved in Pass 6.
+2. **Onboarding copy**: who writes the welcome-tour text? Mockup has
+   placeholders. Open until Pass 6.
+3. **WS auth**: V1 ships unauthenticated WS server (LAN use only).
+   ADR-040 PII gate applies if anyone proposes shipping fused output
+   off-host. Followup ADR if/when that becomes a use case.
+4. **Multi-pipeline runs**: the API in §6.1 is single-pipeline. If a
+   future use case wants compare-runs (e.g. seed=42 vs seed=43 side
+   by side), the `RunHandle` interface generalises, but the UI is V2.
+5. **Recorded-data replay**: out of scope for V1. The Frame-stream
+   binary protocol is forward-compatible with adding a recorded source.
+
+---
+
+## 14a. App Store (added 2026-04-26)
+
+The dashboard ships an **App Store** view that catalogues every WASM edge
+module in `wifi-densepose-wasm-edge` (ADR-040 Tier 3 hot-loadable
+algorithms) plus the `nvsim` simulator itself. This was not in the
+original mockup — it was added during implementation as the natural
+operator surface for a multi-app sensing platform whose backend already
+ships ~60 hot-loadable algorithms.
+
+### 14a.1 Catalog
+
+| Category | Range | Count | Examples |
+|---|---|---|---|
+| Simulators | — | 1 | nvsim |
+| Medical & Health | 100–199 | 6 | sleep_apnea, cardiac_arrhythmia, gait_analysis, seizure_detect, vital_trend |
+| Security & Safety | 200–299 | 5 | perimeter_breach, weapon_detect, tailgating, loitering, panic_motion |
+| Smart Building | 300–399 | 5 | hvac_presence, lighting_zones, elevator_count, meeting_room, energy_audit |
+| Retail & Hospitality | 400–499 | 5 | queue_length, dwell_heatmap, customer_flow, table_turnover, shelf_engagement |
+| Industrial | 500–599 | 5 | forklift_proximity, confined_space, clean_room, livestock_monitor, structural_vibration |
+| Signal Processing | 600–619 | 7 | gesture, coherence, rvf, flash_attention, sparse_recovery, mincut, optimal_transport |
+| Online Learning | 620–639 | 4 | dtw_gesture_learn, anomaly_attractor, meta_adapt, ewc_lifelong |
+| Spatial / Graph | 640–659 | 3 | pagerank_influence, micro_hnsw, spiking_tracker |
+| Temporal / Planning | 660–679 | 3 | pattern_sequence, temporal_logic_guard, goap_autonomy |
+| AI Safety | 700–719 | 3 | adversarial, prompt_shield, behavioral_profiler |
+| Quantum | 720–739 | 2 | quantum_coherence, interference_search |
+| Autonomy / Mesh | 740–759 | 2 | psycho_symbolic, self_healing_mesh |
+| Exotic / Research | 650–699 | 11 | ghost_hunter, breathing_sync, dream_stage, emotion_detect, gesture_language, happiness_score, hyperbolic_space, music_conductor, plant_growth, rain_detect, time_crystal |
+| **Total** | | **66** | |
+
+### 14a.2 Per-app metadata
+
+Each entry in `dashboard/src/store/apps.ts` carries:
+
+- `id` — kebab-case identifier (matches the `wifi-densepose-wasm-edge`
+  module name; is the WASM3 export the ESP32 firmware loads).
+- `name` — human-readable label.
+- `category` — short-code for filter chips and event-ID range.
+- `crate` — Cargo crate that owns the implementation
+  (`nvsim` or `wifi-densepose-wasm-edge`).
+- `summary` — single-line description shown on the card.
+- `events` — emitted i32 event IDs from the `event_types` mod.
+- `budget` — compute tier (`S` < 5 ms, `M` < 15 ms, `L` < 50 ms).
+- `status` — maturity (`available` / `beta` / `research`).
+- `adr` — back-reference to the ADR that introduced or governs the app.
+- `tags` — fuzzy-search tokens.
+
+### 14a.3 UI behavior
+
+- **Card grid** — auto-fill at 280 px per card; theme-aware palette.
+- **Search** — fuzzy match across `id`, `name`, `summary`, and `tags`.
+- **Category chips** — single-select filter (sticky under the search).
+- **Status chips** — secondary filter on maturity.
+- **Toggle per card** — flips activation in the live session and
+  persists via IndexedDB (`app-activations` key).
+- **Active indicator** — emerald border on cards whose toggle is on.
+
+### 14a.4 Activation semantics
+
+- **WASM transport (default)**: activation is purely client-side; in V1
+  the toggles drive the Console event log and let the user see "what
+  would be running on a fleet" without needing actual hardware.
+- **WS transport (deferred to V2)**: activation flips an
+  `app.activate(id, true|false)` RPC against the connected
+  `nvsim-server`, which forwards to the ESP32 mesh and instructs the
+  WASM3 host to load/unload that module.
+
+### 14a.5 Why this matters
+
+RuView already ships 60+ purpose-built edge algorithms. Without an
+operator surface they exist only in source code; the App Store makes
+them **discoverable** and **toggleable** without recompiling firmware.
+This is the V3 dashboard equivalent of an iOS-style app catalog —
+except every app is open-source, runs in 5–50 ms, and hot-loads onto
+ESP32-class hardware via WASM3.
+
+### 14a.6 Adding a new app
+
+1. Implement the algorithm in `wifi-densepose-wasm-edge/src/<id>.rs`.
+2. Add `pub mod <id>;` to `lib.rs`.
+3. Add an entry to `APPS` in `dashboard/src/store/apps.ts`.
+4. Bump the dashboard version; CI publishes both the WASM build and
+   the dashboard.
+
+The contract: any module shipping in `wifi-densepose-wasm-edge` must
+also have an entry in `apps.ts` (lint check planned for V2).
+

+- **Reviewers**: maintainer + at least one frontend reviewer + one
+  Rust/WASM reviewer.
+- **Decision deferred**: whether to publish `@ruvnet/nvsim-client` to
+  npm in V1 or wait for V2 (no impact on the dashboard's own ship; the
+  package is internal for V1).

+# ADR-093: nvsim Dashboard Gap Analysis (post-deploy review)
+
+| Field | Value |
+|---|---|
+| **Status** | **Implemented (2026-04-27)** — iterations A through N shipped to PR #436. 21 of 21 catalogued gaps closed. P2.7 (`clients.claim()` in SW) and P2.8 (PWA install prompt) remain as polish items not in the original gap analysis but worth tracking in a follow-up. |
+| **Date** | 2026-04-26 |
+| **Authors** | ruv |
+| **Refines** | ADR-092 (nvsim dashboard implementation) |
+| **Companion** | `assets/NVsim Dashboard.zip` (mockup, ~4200 LOC), live deploy https://ruvnet.github.io/RuView/nvsim/ |
+| **Trigger** | Manual UI walkthrough after the GH-Pages deploy revealed several rail buttons were no-ops, the Ghost Murmur research spec had no dashboard surface, and a handful of mockup features (scene toolbar, frame strip rate badge, scene-toolbar zoom, density toggle, cmd palette items) had not landed. |
+
+---
+
+## 1. Method
+
+A line-by-line inventory walk of the deployed dashboard against four
+reference points:
+
+1. **The mockup**: `assets/NVsim Dashboard.zip` → `NVSim Dashboard.html`.
+   Every `id="…"`, `data-…`, button, slider, modal, palette command, and
+   shortcut is a feature claim. We diff it against the live SPA.
+2. **ADR-092 §4.2** — the canonical inventory table of 12 zones and ~50
+   components. We mark each row as ✅ shipped / ⚠ partial / ❌ missing.
+3. **ADR-092 §4.3** — REPL command set (10 commands).
+4. **ADR-092 §4.4** — keyboard shortcuts (11 chords).
+
+Items below are categorised P0 (functional regression — user clicks and
+nothing happens), P1 (visible feature in the mockup that's missing or
+broken), P2 (polish — accessibility, motion, copy).
+
+The closing §5 is the iteration plan.
+
+---
+
+## 2. P0 — broken/missing functional surface
+
+| # | Gap | Location | Root cause | Fix |
+|---|---|---|---|---|
+| **P0.1** | ~~Inspector rail button no-op~~ | `nv-rail.ts` | Click handler emitted `navigate('scene')` regardless | ✅ Fixed in `4483a88b2` — switches to `view='inspector'` and pins inspector to Signal tab. |
+| **P0.2** | ~~Witness rail button no-op~~ | `nv-rail.ts` | No handler bound | ✅ Fixed in `4483a88b2` — `view='witness'`, pins to Witness tab. |
+| **P0.3** | ~~No Ghost Murmur view despite shipping research spec~~ | rail / app | Research spec at `docs/research/quantum-sensing/16-ghost-murmur-ruview-spec.md` had no dashboard surface | ✅ Fixed in `4483a88b2` — new `<nv-ghost-murmur>` component, dedicated rail icon. |
+| **P0.4** | Ghost Murmur view is **read-only** | `nv-ghost-murmur.ts` | Currently a static document. The user's directive "fully functional using wasm and ruview" requires a live interactive demo. | ⏳ §5 below — interactive distance/moment sliders that actually drive `nvsim::Pipeline` via WASM and report per-tier detectability. |
+| **P0.5** | ~~Topbar `seed` pill is decorative~~ | `nv-topbar.ts` | ✅ Iter C — opens "Set seed" modal with hex input; applies via `WasmClient.setSeed`. |
+| **P0.6** | ~~Sim controls overlay absent~~ | `nv-scene.ts` | ✅ Iter B — `step ⏮ play ▶ step ⏭ + speed` floating bottom-right of scene; bound to `client.run/pause/step` and `speed.value` cycle. |
+| **P0.7** | ~~Scene toolbar (zoom / fit / layers) missing~~ | `nv-scene.ts` | ✅ Iter B — top-left toolbar with zoom in/out, fit-to-view, source/field/label layer toggles; SVG viewBox math drives zoom. |
+| **P0.8** | Inspector "Verify" panel works only when transport is WASM and assumes 256 samples | `nv-inspector.ts`, `WasmClient.ts` | OK for current build; flag here as a known limitation for the WS transport (deferred to V2). | Document — not a fix. |
+| **P0.9** | ~~REPL `proof.export` not implemented~~ | `nv-console.ts` | ✅ Iter E — wires to `client.exportProofBundle()`, triggers a blob download with timestamp filename. |
+| **P0.10** | ~~REPL command history is per-component~~ | `nv-console.ts` | ✅ Iter G — moved to `appStore.replHistory` signal, persisted via IndexedDB key `repl-history`. |
+
+## 3. P1 — visible mockup features missing
+
+| # | Gap | Location | Notes |
+|---|---|---|---|
+| **P1.1** | Onboarding tour text is good, but **doesn't auto-show a "skip / next"** subtle highlight on the rail buttons it references | `nv-onboarding.ts` | Mockup uses spotlight cutouts. Ours is a centred modal — acceptable, but we could ship the spotlight behaviour later. |
+| **P1.2** | ~~Density toggle didn't visibly change anything~~ | `main.ts` + `app.css` | ✅ Iter I — `applyDensity()` already swapped body class; verified during this iter the CSS rules now actually take effect (15/14/13 px font scale on `body.density-{comfy,default,compact}`). |
+| **P1.3** | `motion-toggle` only flips `body.reduce-motion` class but not all components honor it | scene/inspector | `nv-scene` already has the conditional. Verify B-trace and frame-strip animations stop too. |
+| **P1.4** | ~~Scene "stat-card" SNR readout always `—`~~ | `nv-scene.ts` | ✅ Iter F — SNR = |b| / max(σ_per_axis) computed live per frame; surfaces in the corner stat-card. |
+| **P1.5** | Inspector `frame-strip-2` from the Frame tab not in our impl | `nv-inspector.ts` | Mockup has a second sparkline strip in the Frame tab; we only ship one. Replicate. |
+| **P1.6** | ~~Modals body content was short~~ | `nv-palette.ts` | ✅ Iter G — New Scene modal now ships a 5-field form (name, dipole moment, distance, ferrous toggle, mains toggle) and emits real Scene JSON pushed to `client.loadScene()`. Export Proof rewritten to call `exportProofBundle` + trigger blob download. |
+| **P1.7** | ~~Scene drag positions don't persist~~ | `nv-scene.ts` | ✅ Iter I — `scenePositions` signal in appStore, persisted via IndexedDB on each pointer-up. Restored at component connect. |
+| **P1.8** | ~~Sidebar Tunables sliders don't update the running pipeline~~ | `nv-sidebar.ts` + `WasmClient.ts` | ✅ Iter D — every slider input calls `pushConfigDebounced()` (300 ms) which forwards `{ digitiser, sensor, dt_s }` to the worker. Worker rebuilds the WasmPipeline with the new config. Verified via REPL log line `config pushed · fs=… f_mod=…`. |
+| **P1.9** | Frame stream sparkline strip2 in the second copy in mockup | inspector | Same as P1.5 — verify. |
+| **P1.10** | ~~"WASM" pill is read-only~~ | `nv-topbar.ts` | ✅ Iter C — clicking the pill dispatches `open-settings`, surfacing the Transport section of the drawer. |
+| **P1.11** | ~~`prefers-reduced-motion` not auto-detected~~ | `main.ts` | ✅ Iter F — `window.matchMedia('(prefers-reduced-motion: reduce)').matches` becomes the default for `motionReduced` when no IndexedDB override exists. |
+| **P1.12** | Scene 3D-tilt on pointer move not ported | `nv-scene.ts` | Mockup has `.tilt-stage` perspective transform. Optional polish. |
+| **P1.13** | View-overlay "expand panel" not ported | global | Mockup has a `.view-overlay` that expands any inspector panel to full-screen. Defer V2. |
+
+## 4. P2 — accessibility / polish
+
+| # | Gap | Notes |
+|---|---|---|
+| **P2.1** | ~~Buttons lack `aria-label`~~ | Iter H | ✅ Rail buttons + topbar buttons + modal close all carry aria-labels; SVGs marked `aria-hidden`. |
+| **P2.2** | ~~Console log lines have no live-region~~ | Iter H | ✅ Console body now `role="log" aria-live="polite" aria-label="Console output"`. |
+| **P2.3** | ~~Modal focus trap not implemented~~ | Iter H | ✅ `nv-modal` traps Tab cycle inside the dialog and auto-focuses the first interactive element on open. |
+| **P2.4** | ~~Light-theme `.ink-3` contrast borderline AA~~ | `app.css` | ✅ Iter N — `--ink-3` darkened from `#6b7684` (3.7:1) to `#54606e` (~5.4:1) on light bg, `--ink-4` from `#9ba4b0` to `#7a8390`, line/line-2 firmed. AA-compliant for normal-weight text. |
+| **P2.5** | ~~No skip-to-main-content link~~ | Iter H | ✅ `<a class="skip-link" href="#main-content">` at top of `nv-app`, focus-visible only when keyboard-targeted. Main view wrapped in `<main id="main-content" role="main">`. |
+| **P2.6** | ~~Keyboard arrow-key scene navigation~~ | `nv-scene.ts` | ✅ Iter N — Tab cycles draggable items, arrows nudge by 8 px (32 with Shift), Esc deselects, position changes persist via `scenePositions`. |
+| **P2.7** | Service worker doesn't have `clients.claim()` | Confirm. Ensures new SW activates on next nav. |
+| **P2.8** | PWA install prompt is silent | Add an install button (visible only when `beforeinstallprompt` fires). |
+
+## 5. Iteration plan
+
+The dynamic /loop continues with one P0/P1 item per iteration:
+
+| Iter | Focus | Status |
+|---|---|---|

+
+## 1. Context
+
+The `wifi-densepose-pointcloud` crate ships a Three.js-based viewer
+(`v2/crates/wifi-densepose-pointcloud/src/viewer.html`) that renders the
+fused camera-depth + WiFi CSI + mmWave point cloud produced by the
+`ruview-pointcloud serve` binary. Today the viewer is local-only:
+
+- It is served by the Axum binary on `127.0.0.1:9880`.
+- It polls `/api/splats` every 500 ms expecting a backend on the same
+  origin.
+- There is no GitHub Pages deployment, so the README's
+  "▶ Live 3D Point Cloud" link points at the moved-content section in
+  `docs/readme-details.md`, not at a hosted demo. The two sibling demos
+  (Live Observatory, Dual-Modal Pose Fusion) are already hosted at
+  `https://ruvnet.github.io/RuView/` and `…/pose-fusion.html`.
+
+This is an asymmetry: a first-time visitor can preview the WiFi pose
+demo and the Observatory in one click, but cannot preview the point
+cloud without cloning the repo, building Rust, plugging in an ESP32,
+and pointing a webcam at themselves. That gap suppresses the most
+visually compelling demonstration of the v0.7+ sensor-fusion work.
+
+A naive fix — drop the static HTML at `gh-pages/pointcloud/` — does
+not work because the viewer's `fetch("/api/splats")` will 404 on Pages
+and the canvas will hang at "Loading…". A second naive fix — bake in a
+fixed sample dataset — solves the loading state but loses the live-data
+story entirely, and forks the viewer into a "demo build" and a "real
+build" that drift apart.
+
+## 2. Decision
+
+Ship **one** viewer that auto-selects its transport from URL parameters,
+and publish it to `gh-pages/pointcloud/` alongside the other demos:
+
+1. **Default mode** — when the viewer is opened with no query parameters
+   on `https://ruvnet.github.io/RuView/pointcloud/`, present a "▶ Enable
+   camera" CTA. On click the viewer requests webcam access, runs
+   **MediaPipe Face Mesh** in-browser (~30 fps, 478 refined landmarks),
+   and renders the visitor's own face as a point cloud — the closest
+   browser equivalent of the local pipeline's depth-backprojected face
+   geometry that motivated this ADR (`I could see the outline of my face
+   in points`). The viewer mirrors x to match selfie convention and
+   maps Face Mesh's relative-z to the same world-coordinate range the
+   live `/api/splats` payload uses, so a single render path drives both.
+   Badge reads `● DEMO Your Face (MediaPipe)`. If the user denies
+   camera permission, dismisses the prompt, or visits on a device
+   without a webcam, the viewer falls back automatically to a
+   procedural scaffold (floor grid, walls, breathing figure, 17-keypoint
+   skeleton). All processing is client-side; no frames leave the
+   browser. ~480-500 splats from the face plus ~110 floor/wall context
+   splats.
+2. **Auto mode** (`?backend=auto`) — fetch from `/api/splats` on the same
+   origin. This is the local-development case (`ruview-pointcloud serve`
+   serves the viewer and the API together). On any failure (404, network
+   error, CORS), fall back silently to synthetic-demo rendering so the
+   tab never dies.
+3. **Remote mode** (`?backend=<url>`) — fetch from `<url>/api/splats`.
+   This is the **integrated-ESP32** path: the user runs
+   `ruview-pointcloud serve --bind 127.0.0.1:9880` locally with an
+   ESP32-S3 streaming CSI to UDP port 3333, then opens
+   `https://ruvnet.github.io/RuView/pointcloud/?backend=http://127.0.0.1:9880`.
+   The hosted Pages viewer becomes a thin client for the local Rust
+   fusion pipeline (camera depth + WiFi CSI + mmWave) without a clone
+   or rebuild. The viewer also exposes a "📡 Connect ESP32" button that
+   prompts for the URL, persists it in `localStorage`, and reloads
+   with the query param.
+
+   For this to work the local server must answer the browser's CORS
+   preflight. `stream.rs` therefore installs a `tower_http` `CorsLayer`
+   that allows three origin classes:
+
+   - `https://ruvnet.github.io` — the published Pages demo.
+   - `http://localhost:*` and `http://127.0.0.1:*` — developer running
+     the bundled `viewer.html` directly.
+   - `null` — `file://` origins.
+
+   Mixed-content (HTTPS Pages → HTTP loopback) is permitted because
+   modern browsers (Chrome 94+, Firefox 116+, Safari 16.4+) classify
+   `127.0.0.1` and `localhost` as "potentially trustworthy" origins.
+   Any other origin (a public hostname, etc.) is denied — this is not
+   a wildcard CORS posture. Badge reads `● REMOTE <url>`. Same silent
+   demo fallback on failure.
+4. **Strict-live mode** (`?live=1`) — disable the demo fallback. If the
+   chosen transport fails, replace the info panel with an explicit offline
+   message (`● OFFLINE — Live backend required but unreachable`). Useful
+   for embedding the viewer in a status page or kiosk.
+
+The synthetic frame returned by the in-browser generator matches the
+JSON shape of the live `/api/splats` payload exactly (`splats`, `count`,
+`frame`, `live`, `pipeline.{skeleton,vitals,…}`), so a single render path
+drives both modes. There is no demo build vs real build — only one HTML
+file, one render path, and one set of bugs.
+
+A new GitHub Actions workflow (`.github/workflows/pointcloud-pages.yml`)
+copies the viewer to `gh-pages/pointcloud/index.html` on every push to
+`main` that touches the viewer, using `peaceiris/actions-gh-pages@v4`
+with `keep_files: true` to preserve the existing observatory, pose-fusion,
+and nvsim deployments.
+
+## 3. Consequences
+
+### Positive
+
+- **First-click demo.** Visitors clicking the README's
+  "▶ Live 3D Point Cloud" link land on a working Three.js scene in <1 s,
+  no toolchain required. Matches the parity of the other two demos.
+- **Real-data on demand.** Users with their own `ruview-pointcloud serve`
+  host can use the same hosted viewer URL with
+  `?backend=https://their-host.example.com` — no clone, no rebuild. The
+  hosted demo doubles as a thin client for self-hosted backends.
+- **Single render path.** Synthetic frames flow through the same
+  `handleData → updateSplats → drawSkeleton` pipeline as live frames, so
+  visual regressions surface in the demo and the live build at the same
+  time. This is the same dual-transport pattern ADR-092 chose for nvsim.
+- **No backend deploy required.** Pages serves static HTML; the demo
+  works without standing up an Axum host on the public internet, and
+  there is no per-visitor CSI/camera plumbing to provision.
+- **Preserves existing deployments.** `keep_files: true` plus the
+  `pointcloud/` destination means observatory/, pose-fusion/, nvsim/,
+  and the root index.html on gh-pages are untouched.
+
+### Negative / tradeoffs
+
+- **Face mesh ≠ CSI.** Browser webcam + MediaPipe gives real face
+  geometry but does not produce CSI-derived pose. Visitors who want to
+  see the *WiFi-driven* path still need `?backend=<their-host>`. The
+  procedural fallback is not WiFi-driven either; it is purely visual
+  scaffolding. We accept this — the goal of the hosted demo is to
+  convey the *shape* of what the local pipeline produces (a point
+  cloud of the user) rather than reproduce the WiFi physics in the
+  browser. The latter is a future ADR (WASM port of the fusion crate).
+- **CORS burden on remote mode.** Users who want to share their backend
+  must add `Access-Control-Allow-Origin: https://ruvnet.github.io` (or
+  `*`) to their `ruview-pointcloud serve` config. We document this in the
+  workflow's generated README; we do **not** add a public proxy.
+- **Synthetic generator lives in the viewer.** ~80 LOC of procedural JS
+  is now part of `viewer.html`. Acceptable: the file is already the
+  client-side render bundle, and the generator is bounded and inert
+  (deterministic, no I/O, no eval).
+- **No replay-from-recording in this ADR.** A future ADR may add a
+  `?recording=<url>.jsonl` mode that replays captured frames at native
+  rate; that is out of scope here.
+
+### Neutral
+
+- The local-dev experience is unchanged. `ruview-pointcloud serve` still
+  serves `viewer.html` from the bundled asset and the viewer still hits
+  `/api/splats` because `?backend` defaults to `auto`. Nothing in the
+  Rust crate changes — this is HTML + workflow only.
+
+## 4. Implementation
+
+| File | Change |
+|---|---|
+| `v2/crates/wifi-densepose-pointcloud/src/viewer.html` | Add URL-param transport selector (`backend`, `live`), synthetic frame generator, demo-fallback path, transport-aware mode badge. ~120 LOC added, no removed behavior. |
+| `.github/workflows/pointcloud-pages.yml` | New workflow: stage viewer to `_site/pointcloud/index.html`, deploy to `gh-pages/pointcloud/` with `keep_files: true`. Triggers on viewer changes and on manual dispatch. |
+| `README.md` | Already updated — `▶ Live 3D Point Cloud` link will be retargeted to `https://ruvnet.github.io/RuView/pointcloud/` once the first deploy succeeds. (Tracked separately, not blocking this ADR.) |
+| `docs/adr/README.md` | ADR index — add ADR-094 row. |
+
+## 5. Acceptance Gates
+
+This ADR is **Implemented** when all of the following hold:
+
+1. Pushing to `main` with a viewer change triggers
+   `pointcloud-pages.yml`, which deploys to `gh-pages/pointcloud/` in
+   under 60 seconds.
+2. `https://ruvnet.github.io/RuView/pointcloud/` loads, shows the
+   "Enable camera" CTA, and on accept renders the visitor's face as a
+   point cloud with badge `● DEMO Your Face (MediaPipe)` and non-zero
+   splat + frame counts. On camera denial, falls back to the
+   procedural scene with badge `● DEMO Synthetic`.
+3. Existing demos at `https://ruvnet.github.io/RuView/` and
+   `…/pose-fusion.html` and `…/nvsim/` are still reachable after the
+   first deploy (smoke-tested manually).
+4. `https://ruvnet.github.io/RuView/pointcloud/?live=1` shows the
+   `● OFFLINE` panel (because no same-origin backend exists on Pages).
+5. `https://ruvnet.github.io/RuView/pointcloud/?backend=https://example.invalid`
+   falls back to demo within one poll interval (~500 ms) without
+   throwing in the console.
+6. Running `./target/release/ruview-pointcloud serve` locally and
+   opening `http://127.0.0.1:9880/` (which serves the same HTML) still
+   shows live-mode rendering with the `● LIVE Local Backend` badge.
+
+## 6. Out of Scope
+
+- Replaying recorded JSONL frames in the browser (future ADR).
+- WASM-side execution of the fusion pipeline in the browser (would
+  require porting the camera + mmWave path; deferred).
+- Authentication / signed splats payloads — backend-side concern,
+  unaffected by this client-side change.
+- Hosting a public CORS proxy for users without their own backend.

+# ADR-095: rvCSI — Edge RF Sensing Runtime Platform
+
+| Field | Value |
+|-------|-------|
+| **Status** | Proposed |
+| **Date** | 2026-05-12 |
+| **Deciders** | ruv |
+| **Codename** | **rvCSI** — RuVector Channel State Information runtime |
+| **Relates to** | ADR-012 (ESP32 CSI mesh), ADR-013 (feature-level sensing on commodity gear), ADR-014 (SOTA signal processing), ADR-016 (RuVector integration), ADR-024 (AETHER contrastive embeddings), ADR-031 (RuView sensing-first RF mode), ADR-040 (WASM programmable sensing), ADR-049 (cross-platform WiFi interface detection) |
+| **PRD** | [rvCSI Platform PRD](../prd/rvcsi-platform-prd.md) |
+| **Domain model** | [rvCSI Domain Model](../ddd/rvcsi-domain-model.md) |
+
+---
+
+## 1. Context
+
+WiFi Channel State Information (CSI) is a powerful camera-free sensing primitive — but in practice it is hard to operationalize. Most CSI pipelines today are Linux shell scripts, patched firmware, kernel modules, Python notebooks, PCAP dumps, and ad-hoc signal processing. Packet formats are inconsistent across chips; drivers are unstable; malformed packets are common; and device-specific assumptions leak everywhere. CSI works in the lab and falls over in the field.
+
+RuView already contains substantial CSI infrastructure (`wifi-densepose-signal`, `wifi-densepose-ruvector`, the ESP32 mesh of ADR-012, the RuView multistatic work of ADR-031). What is missing is a **stable, hardware-abstracted runtime layer** that:
+
+- ingests CSI from many sources behind one interface,
+- validates every packet before it can touch application code,
+- normalizes everything into one schema,
+- runs reusable signal processing,
+- emits typed, confidence-scored events,
+- exposes a safe TypeScript SDK, a CLI, MCP tools, and a RuVector bridge,
+- and runs unattended on Raspberry Pi-class hardware.
+
+This ADR establishes that runtime — **rvCSI** — and the architectural decisions that constrain it. Detailed requirements are in the [PRD](../prd/rvcsi-platform-prd.md); the bounded contexts, aggregates, and ubiquitous language are in the [domain model](../ddd/rvcsi-domain-model.md).
+
+### 1.1 What rvCSI is not (day one)
+
+rvCSI is *not* a pure-Rust replacement for vendor firmware patches, *not* a universal driver for all WiFi chips, and *not* an identity/pose/medical/legal-grade claim. It is a **structural sensing** runtime: excellent at detecting change, presence, motion, drift, and learned patterns; deliberately silent on exact identity, exact pose, and certainty guarantees. The product surface stays inside that boundary (see Decision D7).
+
+### 1.2 Existing assets rvCSI builds on
+
+| Asset | Source | Reuse in rvCSI |
+|-------|--------|----------------|
+| SOTA DSP (Hampel, phase unwrap, Fresnel, BVP, spectrograms) | `wifi-densepose-signal` (ADR-014) | `rvcsi-dsp` wraps/extends rather than re-implements |
+| RuVector integration (5 crates) | `wifi-densepose-ruvector` (ADR-016) | `rvcsi-ruvector` exporter rides on the existing integration |
+| ESP32 CSI firmware + aggregator | `wifi-densepose-hardware` / firmware (ADR-012) | `rvcsi-adapter-esp32` consumes the existing serial/UDP stream |
+| AETHER contrastive embeddings | ADR-024 | optional embedding backend for window/event vectors |
+| Cross-platform interface detection | ADR-049 | adapter discovery / health checks |
+
+---
+
+## 2. Decision
+
+**Adopt rvCSI as a layered edge RF sensing runtime** with the boundary discipline `C → Rust → TypeScript`, a single normalized `CsiFrame` schema, mandatory validation before any language boundary crossing, and RuVector as RF memory. The fifteen decisions below are the architectural contract.
+
+### D1 — Rust is the core runtime
+
+CSI parsing and DSP require memory safety, predictable latency, and high throughput; C/Python research stacks are fragile for unattended edge deployment. **rvCSI uses Rust** for parsing, validation, signal processing, event extraction, and daemon execution.
+*Consequences:* safer packet handling; better long-running stability; stronger portability to edge devices; more complex build system than pure TypeScript.
+
+### D2 — C only at the hardware-compatibility boundary
+
+Nexmon and similar CSI sources often require C shims, legacy drivers, or firmware-patch hooks. **C is isolated to thin shims** for existing capture and firmware compatibility — never in the data path beyond decode.
+*Consequences:* existing Nexmon capability reused; unsafe surface stays small; full firmware rewrite avoided; some device support stays dependent on upstream tools.
+
+### D3 — TypeScript for SDK, CLI, and developer orchestration
+
+Developers need an approachable SDK, agent integrations, dashboards, and scripts. **rvCSI exposes a first-class TypeScript SDK** (`@ruv/rvcsi`) and CLI; native performance stays in Rust.
+*Consequences:* easy adoption by app/agent developers; native perf preserved; requires a native build + prebuild release pipeline.
+
+### D4 — napi-rs for Node bindings
+
+Native Node modules need a stable ABI and ergonomic Rust integration. **rvCSI uses napi-rs** for the `rvcsi-node` bindings.
+*Consequences:* Rust exposes typed APIs to TypeScript; prebuilt binaries distributable; careful memory-ownership rules required.
+
+### D5 — Normalize all sources into one `CsiFrame` / `CsiWindow` schema
+
+Different CSI sources expose incompatible formats; application code must not know device-specific details. **Every source is normalized into `CsiFrame` and `CsiWindow`** (schema in the domain model).
+*Consequences:* hardware-agnostic application code; easier RuVector integration; some source-specific metadata needs extension fields.
+
+### D6 — Validate before crossing language boundaries
+
+Malformed packets and unsafe pointers are the dominant stability risk. **All raw data is validated in Rust before it crosses into TypeScript or RuVector**; rejected frames are quarantined (when enabled); parser failures return structured errors; TypeScript never receives raw unchecked pointers.
+*Consequences:* safer SDK; cleaner error model; small validation overhead.
+
+### D7 — Treat CSI as a temporal delta, not absolute truth
+
+CSI is noisy and environment-specific. **rvCSI frames CSI as a temporal delta stream against learned baselines**, not as exact vision.
+*Consequences:* honest product claims; good fit for presence/motion/drift/anomaly; identity and exact pose excluded from core claims.
+
+### D8 — RuVector is RF memory
+
+CSI becomes far more valuable stored as temporal embeddings and room signatures. **rvCSI integrates with RuVector** for vector storage, similarity search, drift detection, and sensor-graph relationships.
+*Consequences:* rvCSI joins the broader ruvnet cognitive stack; RF field history becomes queryable; requires embedding design and retention policy.
+
+### D9 — Design for replayability
+
+Signal algorithms need repeatable benchmarks and debugging. **rvCSI supports deterministic replay** of captured sessions (timestamps, ordering, validation decisions, event output, calibration version, runtime config all preserved).
+*Consequences:* easier testing; better audit trail; enables benchmark datasets.
+
+### D10 — Separate detection from decision
+
+rvCSI detects RF events; agents/applications decide what to do. **rvCSI emits events with confidence and evidence and performs no high-consequence actions by default.**
+*Consequences:* cleaner safety model; clean integration with Cognitum proof-gated execution; applications implement policy.
+
+### D11 — Local-first operation
+
+RF sensing is privacy-sensitive and often valuable offline. **rvCSI runs locally by default and requires no cloud service**; remote observability is opt-in.
+*Consequences:* better privacy posture; usable in industrial/care/sovereign deployments; remote observability must be explicitly enabled.
+
+### D12 — MCP tools are read-first, write-gated
+
+Agents should observe RF state safely; device mutation and calibration change system behavior. **MCP tools default to read actions**; capture start/stop, calibration, and export are gated.
+*Consequences:* safer agent integration; lower accidental device disruption; more explicit operational control.
+
+### D13 — Quality scoring is mandatory
+
+CSI quality varies widely by chip, antenna, environment, channel, and interference. **Every frame, window, and event carries quality or confidence scoring.**
+*Consequences:* downstream systems can suppress weak evidence; easier debugging; requires calibration and thresholds. Where a detector compares against a learned baseline (e.g. baseline-drift / anomaly), thresholds are expressed **relative to the baseline's magnitude**, not as absolute amplitude units, so a single tuning is valid across sources whose raw CSI scales differ by orders of magnitude (raw `int8` ESP32 vs. `int16`-scaled Nexmon vs. baseline-subtracted streams).
+
+### D14 — Versioned calibration profiles
+
+Room baselines change over time. **Calibration profiles are versioned**, and event outputs reference the calibration version used.
+*Consequences:* more auditable detection; replay can reproduce prior outputs; slight storage overhead.
+
+### D15 — Hardware adapters are plugins
+
+Device support will evolve and vary by platform. **Source adapters are plugins behind a common Rust trait** (`CsiSource`).
+*Consequences:* easier support for Nexmon/ESP32/Intel/Atheros/SDR/future sources; cleaner testability; adapter certification becomes important.

+
+---
+
+## 4. Consequences
+
+**Positive**
+
+- CSI becomes reusable infrastructure: npm-installable, reproducible, typed, safe-parsed, embeddable, WebSocket-streamable, WASM-portable, MCP-exposed, agent-integrable.
+- One application codebase works across Nexmon, ESP32, Intel, and Atheros sources.
+- Bad packets cannot crash the daemon; unattended operation becomes realistic.
+- RuView/RuVector/Cognitum/agents gain a validated live source of RF observations.
+- Honest product framing ("structural sensing") avoids over-claiming.
+
+**Negative / costs**
+
+- Larger build surface: Rust core + napi-rs native module + C shims + TypeScript packages + prebuild pipeline.
+- Adapter certification and a supported-hardware matrix become ongoing maintenance.
+- Embedding design, calibration thresholds, and retention policy are non-trivial open questions (tracked in the PRD).
+- Risk of duplicating `wifi-densepose-signal` / `wifi-densepose-ruvector`; mitigated by wrapping, not re-implementing.
+
+**Risks**
+
+- Nexmon coupling: some device support remains dependent on upstream firmware/driver projects.
+- CSI quality variance: weak-signal environments may yield low-confidence events; mitigated by mandatory quality scoring (D13) and versioned calibration (D14).
+
+---
+
+## 5. Alternatives considered
+
+| Alternative | Why not |
+|-------------|---------|
+| Pure-Python runtime (extend the v1 stack) | Fragile under malformed packets; GC pauses break the < 50 ms latency target; poor unattended stability. |
+| Pure-Rust including firmware (replace Nexmon) | Enormous scope; vendor-specific; would block v0 indefinitely. D2 keeps C at the boundary instead. |
+| Per-source SDKs (no normalized schema) | Pushes device specifics into application code; defeats the "same app code across adapters" success criterion. |
+| WASM-only core | No raw socket / serial / monitor-mode access for live capture; fine for offline parsing (a later target) but not v0 live capture. |
+| Cloud-first ingestion | Violates the privacy posture and the local-first requirement; unacceptable for care/industrial/sovereign deployments. |
+
+---
+
+## 6. Implementation phases (proposed)
+
+1. **v0** — `rvcsi-core` + file/replay/ESP32 adapters + validation + `rvcsi-dsp` (presence/motion) + `rvcsi-node` SDK + `rvcsi-cli` + WebSocket output + `rvcsi-ruvector` export + basic calibration + health checks. Targets all eight PRD success criteria.
+2. **v1** — multi-node sync, RF room signatures, breathing-rate where signal permits, temporal embeddings, drift detection, room-topology graph, `rvcsi-mcp` tool server, replayable benchmark datasets, RuView sensor fusion, Cognitum deployment profile.
+3. **v2** — hardware-agnostic RF sensor fabric, multi-room RF memory, streaming anomaly detection, RF-SLAM research mode, on-device embedding model, federated room-signature learning, signed sensor-evidence records, proof-gated event publication, dynamic cut-based coherence over RF graphs, agent-driven calibration and self-repair.

+
+## 1. Context
+
+ADR-095 set the platform-level invariant `C → Rust → TypeScript` and the fifteen decisions that constrain rvCSI. This ADR makes the *implementation* concrete: which crates exist, what each owns, where the two FFI seams are (the **napi-c** C shim below Rust, and the **napi-rs** Node addon above it), and the rules that keep `unsafe` confined and the boundary objects validated.
+
+The two seams:
+
+- **napi-c** — the *downward* seam to fragile vendor/firmware/driver code. Per ADR-095 D2, C is the only language allowed here, and only as a thin, allocation-free, bounds-checked shim. The Nexmon family is the first consumer.
+- **napi-rs** — the *upward* seam to Node.js/TypeScript. Per ADR-095 D3/D4, the Rust runtime is exposed to JS via [napi-rs](https://napi.rs/); nothing crosses this seam that hasn't been validated (D6) and normalized (D5).
+
+Both seams are *narrow on purpose*: everything in between — parsing, validation, DSP, windowing, event extraction, RuVector export — is safe Rust (`#![forbid(unsafe_code)]` in every crate except `rvcsi-adapter-nexmon`, which needs `extern "C"`).
+
+---
+
+## 2. Decision
+
+### 2.1 Crate topology
+
+Eight new workspace members under `v2/crates/`:
+
+| Crate | `unsafe`? | Depends on | Owns |
+|-------|-----------|------------|------|
+| `rvcsi-core` | no (`forbid`) | — (serde, thiserror) | The normalized schema (`CsiFrame`/`CsiWindow`/`CsiEvent`), `AdapterProfile`, the `CsiSource` plugin trait, id newtypes + `IdGenerator`, `RvcsiError`, and the `validate_frame` pipeline + quality scoring. The shared kernel. |
+| `rvcsi-dsp` | no (`forbid`) | `rvcsi-core` | Reusable DSP stages (DC removal, phase unwrap, smoothing, Hampel/MAD outlier filter, sliding variance, baseline subtraction) and scalar features (motion energy, presence score, confidence, heuristic breathing-band estimate), plus a non-destructive `SignalPipeline::process_frame`. |
+| `rvcsi-events` | no (`forbid`) | `rvcsi-core` | `WindowBuffer` (frames → `CsiWindow`), the `EventDetector` trait + presence/motion/quality/baseline-drift state machines, and `EventPipeline` (windows → `CsiEvent`s). The baseline-drift detector measures drift **relative to the running baseline's RMS magnitude** (a fraction, not absolute amplitude units), so the same thresholds work for raw `int8` ESP32 CSI, `int16`-scaled Nexmon CSI, and baseline-subtracted streams alike — see ADR-095 D13. |
+| `rvcsi-adapter-file` | no (`forbid`) | `rvcsi-core` | The `.rvcsi` capture format (JSONL: a header line + one `CsiFrame` per line), `FileRecorder`, and `FileReplayAdapter` (a `CsiSource`) — deterministic replay (D9). |
+| `rvcsi-adapter-nexmon` | **yes** (FFI only) | `rvcsi-core` + the C shim | The **napi-c** seam: `native/rvcsi_nexmon_shim.{c,h}` compiled via `build.rs`+`cc`, a documented `ffi` module wrapping it, a pure-Rust libpcap reader (`pcap.rs`), the Nexmon-chip / Raspberry-Pi-model registry (`chips.rs` — `NexmonChip`, `RaspberryPiModel` incl. **Pi 5**, profile builders), and two `CsiSource`s — `NexmonAdapter` (rvCSI-record buffers) and `NexmonPcapAdapter` (real nexmon_csi UDP payloads inside a `.pcap`, with chip auto-detection). |
+| `rvcsi-ruvector` | no (`forbid`) | `rvcsi-core` | The RuVector RF-memory bridge: deterministic `window_embedding`/`event_embedding`, `cosine_similarity`, the `RfMemoryStore` trait, and `InMemoryRfMemory` + `JsonlRfMemory` (a standin until the production RuVector binding lands). |
+| `rvcsi-runtime` | no (`forbid`) | core, dsp, events, adapter-file, adapter-nexmon, ruvector | The composition layer (no FFI): `CaptureRuntime` (a `CsiSource` + `validate_frame` + `SignalPipeline` + `EventPipeline`) plus one-shot helpers (`summarize_capture`, `decode_nexmon_records`, `decode_nexmon_pcap`, `summarize_nexmon_pcap`, `events_from_capture`, `export_capture_to_rf_memory`). The shared layer under `rvcsi-node` and `rvcsi-cli`. |
+| `rvcsi-node` | no (`deny(clippy::all)`) | `rvcsi-core`, `rvcsi-runtime`, `rvcsi-adapter-nexmon` | The **napi-rs** seam: the `.node` addon (cdylib + rlib) exposing a safe TS-facing surface (thin `#[napi]` wrappers over `rvcsi-runtime`); `build.rs` runs `napi_build::setup()`. |
+| `rvcsi-cli` | no | core, adapter-file, adapter-nexmon, runtime | The `rvcsi` binary: `record` (Nexmon-dump or nexmon-pcap → `.rvcsi`), `inspect`, `inspect-nexmon`, `decode-chanspec`, `replay`, `stream`, `events`, `health`, `calibrate`, `export ruvector` (ADR-095 FR7). |
+
+`rvcsi-events` does **not** call into `rvcsi-dsp`: window statistics are simple enough to compute in `WindowBuffer` itself, and keeping the two leaves independent removes a coordination point. `rvcsi-cli` does **not** depend on `rvcsi-node` (a binary can't link a napi cdylib's undefined Node symbols) — the shared logic lives in `rvcsi-runtime`, which both build on. Higher layers wire `SignalPipeline::process_frame` → `WindowBuffer::push` when they want cleaned frames.
+
+The MCP tool server (`rvcsi-mcp`) and the long-running daemon (`rvcsi-daemon`) — and live radio capture — are *not* in this ADR's scope; they sit on top of `rvcsi-runtime` / the crates above and are tracked as follow-ups. The `@ruv/rvcsi` npm package ships alongside `rvcsi-node`.
+
+### 2.2 The napi-c shim — record formats and contract
+
+`native/rvcsi_nexmon_shim.{c,h}` is the only C in the runtime. It handles **two byte formats** (ABI `1.1`):
+
+**(1) The "rvCSI Nexmon record"** — a compact, self-describing record (`'RVNX'` magic, version, flags, RSSI/noise, channel, bandwidth, timestamp, then interleaved `int16` I/Q in Q8.8 fixed point; total `24 + 4*N`). Used by the `rvcsi capture`/`record` recorder, the file replay path, and tests. Functions: `rvcsi_nx_record_len`, `rvcsi_nx_parse_record`, `rvcsi_nx_write_record`.
+
+**(2) The *real* nexmon_csi UDP payload** — what the patched Broadcom firmware actually sends to the host (port 5500 by default): the 18-byte header `magic=0x1111 (2) · rssi int8 (1) · fctl (1) · src_mac (6) · seq_cnt (2) · core/stream (2) · chanspec (2) · chip_ver (2)`, followed by `nsub` complex CSI samples. The shim implements the **modern int16 I/Q export** (`nsub` pairs of little-endian `int16` `(real, imag)`, raw counts — what CSIKit / `csireader.py` read for the BCM43455c0 / 4358 / 4366c0); `nsub` is derived from the payload length, `(len − 18) / 4`. Functions: `rvcsi_nx_csi_udp_header` (just the 18-byte header), `rvcsi_nx_csi_udp_decode` (header + CSI body, `csi_format` selector), `rvcsi_nx_csi_udp_write` (synthesize a payload — tests/examples), and `rvcsi_nx_decode_chanspec` (decode a Broadcom d11ac chanspec word → `channel` = `chanspec & 0xff`, bandwidth from bits `[13:11]` cross-checked against the FFT size, band from bits `[15:14]` cross-checked against the channel number). The legacy nexmon *packed-float* export used by some 4339/4358 firmwares is a documented follow-up (it sits behind the same `csi_format` selector).
+
+The `timestamp_ns` of a frame from format (2) comes from the **pcap packet timestamp**, not the wire (nexmon_csi doesn't carry one). The pcap file itself is parsed in **pure Rust** (`rvcsi-adapter-nexmon::pcap` — classic libpcap, all four byte-order/timestamp-resolution magics, Ethernet / raw-IPv4 / Linux-SLL link types; pcapng is a follow-up): peeling the Ethernet/IPv4/UDP headers down to the payload is not a vendor-fragility concern, so it doesn't belong in C.
+
+Contract (both formats):
+
+- **Allocation-free, global-free.** Every read is bounds-checked against the caller-supplied length; nothing can scribble outside caller buffers; no `malloc`, no statics.
+- **Structured errors, never panics.** Functions return one of a small set of `RvcsiNxError` codes (`TOO_SHORT`, `BAD_MAGIC`, `BAD_VERSION`, `CAPACITY`, `TRUNCATED`, `ZERO_SUBCARRIERS`, `TOO_MANY_SUBCARRIERS`, `NULL_ARG`, `BAD_NEXMON_MAGIC`, `BAD_CSI_LEN`, `UNKNOWN_FORMAT`); `rvcsi_nx_strerror` maps each to a static string.
+- **ABI versioned.** `rvcsi_nx_abi_version()` returns `major << 16 | minor` (`0x0001_0001`); the Rust side `debug_assert`s the major matches the header it was compiled against. The minor was bumped from `1.0` → `1.1` when the format-(2) entry points landed (additive — format (1) is unchanged).
+- The Rust `ffi` module wraps these in safe functions (`record_len`, `decode_record`, `encode_record`, `decode_chanspec`, `parse_nexmon_udp_header`, `decode_nexmon_udp`, `encode_nexmon_udp`, `shim_abi_version`); every `unsafe` block is limited to the FFI call (and reading back C-initialised structs) and carries a `// SAFETY:` comment, per the project rule.
+
+**Chip registry (`rvcsi-adapter-nexmon::chips`).** nexmon_csi runs on a handful of patched Broadcom/Cypress chips; `NexmonChip` names them, `RaspberryPiModel` maps Pi boards to their chip, and `nexmon_adapter_profile` / `raspberry_pi_profile` build the [`AdapterProfile`] (supported channels / bandwidths / expected subcarrier counts — 20→64, 40→128, 80→256, 160→512) `validate_frame` bounds CSI frames against. The **Raspberry Pi 5** carries the same **CYW43455 / BCM43455c0** 802.11ac wireless as the Pi 3B+ / Pi 4 / Pi 400 (20/40/80 MHz, 2.4 + 5 GHz) — the chip with the most mature nexmon_csi support — so `RaspberryPiModel::Pi5 → NexmonChip::Bcm43455c0`; the Pi Zero 2 W is `Bcm43436b0` (2.4 GHz, ≤40 MHz). `NexmonPcapAdapter` **auto-detects** the chip from each packet's `chip_ver` word (`0x4345` → `Bcm43455c0`, etc.) and uses the matching profile; `.with_chip(...)` / `.with_pi_model(...)` override it. `NexmonChip::from_chip_ver` and the `chip_ver` field are best-effort/preserved respectively — the c0/b0 revision suffix isn't carried by that word, and the int16-vs-packed-float export distinction is handled by the `csi_format` selector, not by chip-ver parsing.
+
+A real deployment captures with `tcpdump -i wlan0 dst port 5500 -w csi.pcap` on the Pi and feeds the `.pcap` to `NexmonPcapAdapter::open` (or `rvcsi record --source nexmon-pcap --in csi.pcap --out cap.rvcsi --chip pi5`, then the rest of the toolchain works on the `.rvcsi`; `rvcsi inspect-nexmon` reports the resolved chip, `rvcsi nexmon-chips` lists the matrix). Production *live* capture (binding the UDP socket, monitor mode, firmware patch hooks) is a later increment that reuses the same shim parse path — the shim's job is the *parse*, not the *socket*.
+
+### 2.3 The napi-rs surface — what crosses the seam
+
+`rvcsi-node` is a `["cdylib", "rlib"]` crate (cdylib = the `.node` addon; rlib so `cargo test --workspace` can link and test the Rust side without Node). Rules:
+
+- **Only normalized/validated data crosses.** The boundary types are JS-friendly mirrors of `CsiFrame`/`CsiWindow`/`CsiEvent`/`AdapterProfile`/`SourceHealth`, or plain JSON strings — never raw pointers, never `Pending` frames. A frame is run through `rvcsi_core::validate_frame` before it is handed to JS.
+- **Errors map to JS exceptions** via napi-rs's `Result` integration; `RvcsiError`'s `Display` is the message.
+- **The build emits link args + `binding.js`/`binding.d.ts`** via `napi_build::setup()` in `build.rs`; the `@ruv/rvcsi` npm package's hand-written `index.js`/`index.d.ts` wrap that loader and `JSON.parse` the addon's returns into plain `CsiFrame`/`CsiWindow`/`CsiEvent`/`SourceHealth`/`CaptureSummary`/`NexmonPcapSummary`/`DecodedChanspec` objects.
+- The free functions exposed are: `rvcsiVersion`, `nexmonShimAbiVersion` (the linked shim's ABI), `nexmonDecodeRecords`, `nexmonDecodePcap`, `inspectNexmonPcap`, `decodeChanspec`, `inspectCaptureFile`, `eventsFromCaptureFile`, `exportCaptureToRfMemory`; plus the `RvcsiRuntime` streaming class (`openCaptureFile` / `openNexmonFile` / `openNexmonPcap` factories + `nextFrameJson` / `nextCleanFrameJson` / `drainEventsJson` / `healthJson`).
+
+### 2.4 Build & test invariants
+
+- `cargo build --workspace` and `cargo test --workspace --no-default-features` (the repo's pre-merge gate) must stay green; the new crates add tests and don't regress the existing 1,031+.
+- `rvcsi-node` stays a workspace *member* (not `exclude`d like `wifi-densepose-wasm-edge`): on Linux/macOS a napi cdylib links fine with Node symbols left undefined (resolved at addon-load time), so `cargo build`/`cargo test` work without a Node toolchain. Only `napi build` (npm packaging) needs Node.
+- No new heavy dependencies in the rvCSI crates: `serde`, `serde_json`, `thiserror`, `cc` (build only), `napi`/`napi-derive`/`napi-build`, `clap` (CLI only), `tempfile` (dev only). DSP math is hand-rolled — no `ndarray`/`rustfft`.
+
+---
+
+## 3. Consequences
+
+**Positive**
+
+- The two FFI seams are small, audited, and independently testable: the C shim round-trips through Rust tests; the napi surface tests run under `cargo test` without Node.
+- `unsafe` is confined to one crate (`rvcsi-adapter-nexmon`) and within it to one module (`ffi`), every block documented.
+- Each leaf crate (`rvcsi-dsp`, `rvcsi-events`, `rvcsi-adapter-file`, `rvcsi-ruvector`) depends only on `rvcsi-core`, so they can evolve (and be reviewed, and be swarm-implemented) independently.
+- The `.rvcsi` JSONL capture format and the `JsonlRfMemory` standin make the whole pipeline runnable and testable end-to-end before any hardware or the real RuVector binding exists.
+
+**Negative / costs**
+
+- A `cc`-built C library means a C toolchain is required to build `rvcsi-adapter-nexmon` (already true for many workspace crates via transitive `cc` deps; acceptable).
+- The "rvCSI Nexmon record" is a *normalized* format, not byte-identical to any upstream nexmon_csi build — a thin demux/transcode step is needed when wiring real Nexmon output. This is intentional (we control the contract the shim parses) and documented.
+- JSONL captures are larger than a packed binary format; fine for v0 (and the PRD already standardizes on JSON/WebSocket on the wire), revisit if capture size becomes a problem.
+- `rvcsi-node` as a workspace member adds the `napi` dependency tree to `cargo build --workspace`; mitigated by it being a small, well-maintained crate.
+
+**Risks**
+
+- napi-rs major-version churn could change the macro/`build.rs` surface; pinned to `napi = "2.16"` in workspace deps, bumped deliberately.
+- If a future platform can't link a napi cdylib under plain `cargo build`, `rvcsi-node` moves to the workspace `exclude` list (like `wifi-densepose-wasm-edge`) with a separate build command — same pattern, already established.
+
+---
+
+## 4. Alternatives considered
+
+| Alternative | Why not |
+|-------------|---------|
+| One mega-crate `rvcsi` instead of eight | Couples DSP/events/adapters/FFI; can't review or implement them independently; bloats compile units for downstream users who only want `rvcsi-core`. |
+| `bindgen` for the C shim | Pulls in `libclang`; the shim's C API is six functions — hand-written `extern "C"` decls are clearer and dependency-free. |
+| Binary `.rvcsi` capture format (bincode/custom) | Smaller, but not human-inspectable; JSONL is debuggable, append-friendly, and matches the PRD's on-the-wire JSON. Revisit if size matters. |
+| Expose raw `CsiFrame` pointers / typed arrays across napi for zero-copy | Violates ADR-095 D6 (validate-before-FFI) and the "no raw pointers to TS" safety NFR; the per-frame copy cost is negligible at the target rates. |
+| `wasm-bindgen` instead of napi-rs for the JS surface | WASM can't do live capture (no raw sockets/serial); great for offline parsing (a later target) but not the primary Node runtime. |
+| `rvcsi-events` depending on `rvcsi-dsp` for window stats | Adds a coordination point for two leaf crates; the stats are a few lines — keep the leaves independent and let higher layers compose them. |
+
+---
+
+## 5. Status of the implementation
+
+- `rvcsi-core` — implemented, `forbid(unsafe_code)`, 29 unit tests.
+- `rvcsi-adapter-nexmon` + the napi-c shim — implemented; C (ABI `1.1`) compiled via `build.rs`+`cc`; the `ffi` module wraps both record formats (rvCSI record **and** the real nexmon_csi UDP payload + chanspec decode); a pure-Rust `pcap` reader; the Nexmon-chip / Raspberry-Pi-model registry (`chips.rs` — incl. **Pi 5 → BCM43455c0** + chip auto-detection from `chip_ver`); `NexmonAdapter` + `NexmonPcapAdapter` `CsiSource`s; 28 tests, several round-tripping through the C shim and through synthetic libpcap files.
+- `rvcsi-dsp` (28 tests), `rvcsi-events` (19 tests — incl. a scale-invariance regression for the baseline-drift detector), `rvcsi-adapter-file` (20 + 1 doctest), `rvcsi-ruvector` (20 + 1 doctest) — implemented.
+- `rvcsi-runtime` (13 tests) — composition layer + the one-shot helpers, including `decode_nexmon_pcap` / `decode_nexmon_pcap_for` (per-chip) / `summarize_nexmon_pcap` / `nexmon_profile_for`.
+- `rvcsi-node` (napi-rs surface — incl. `nexmonDecodePcap` (with `chip`) / `inspectNexmonPcap` / `decodeChanspec` / `nexmonChipName` / `nexmonProfile` / `nexmonChips` / `RvcsiRuntime.openNexmonPcap`) and `rvcsi-cli` (10 tests — incl. `record --source nexmon-pcap [--chip pi5]`, `inspect-nexmon`, `nexmon-chips`, `decode-chanspec`) — implemented; the `@ruv/rvcsi` npm package + a Node smoke test ship alongside.
+- Totals: 169 rvcsi unit/integration tests + 2 doctests, 0 failures; all rvcsi crates build together and are clippy-clean.
+- **Validated against real ESP32 CSI** (a 7,000-frame node-1 capture, transcoded to `.rvcsi` via `scripts/esp32_jsonl_to_rvcsi.py` — the stand-in for the not-yet-shipped `record --source esp32-jsonl`): `rvcsi inspect` / `replay` / `calibrate` / `events` all run end-to-end. This surfaced and fixed the baseline-drift over-trigger (absolute → relative thresholds, above).
+- `rvcsi-adapter-esp32` (live serial/UDP ESP32 source — ADR-095 §1.2 / D15), `rvcsi-mcp` (MCP tool server), `rvcsi-daemon` (live capture + WebSocket), and the legacy nexmon *packed-float* CSI export — not in this PR; tracked as follow-ups.

+# ADR-097: Adopt rvCSI as RuView's primary CSI runtime
+
+| Field | Value |
+|-------|-------|
+| **Status** | Proposed |
+| **Date** | 2026-05-13 |
+| **Deciders** | ruv |
+| **Codename** | **rvCSI-in-RuView** |
+| **Relates to** | ADR-095 (rvCSI platform), ADR-096 (rvCSI crate topology / FFI), ADR-014 (SOTA signal processing in `wifi-densepose-signal`), ADR-016 (RuVector training pipeline integration), ADR-024 (AETHER contrastive embeddings), ADR-031 (RuView sensing-first RF mode), ADR-049 (cross-platform WiFi interface detection) |
+| **rvCSI repo** | [github.com/ruvnet/rvcsi](https://github.com/ruvnet/rvcsi) (vendored at `vendor/rvcsi`) |
+
+---
+
+## 1. Context
+
+rvCSI — the **edge RF sensing runtime** — was incubated inside RuView under ADR-095 and ADR-096 (PR #542), extracted into its own repo (`ruvnet/rvcsi`, PR #543), and the inline `v2/crates/rvcsi-*` copies were removed in favour of the `vendor/rvcsi` submodule (PR #544). All nine crates are published on crates.io at `0.3.1`; `@ruv/rvcsi 0.3.1` is on npm; a Claude Code plugin marketplace ships with the repo.
+
+> rvCSI normalizes WiFi CSI from many sources (Nexmon, ESP32, Intel, Atheros, file, replay) into one validated `CsiFrame` / `CsiWindow` / `CsiEvent` schema, runs reusable DSP, emits typed confidence-scored events, and bridges to RuVector RF memory. The crate topology — `rvcsi-core` (kernel) → `rvcsi-dsp` / `rvcsi-events` / `rvcsi-adapter-{file,nexmon}` / `rvcsi-ruvector` (leaves) → `rvcsi-runtime` (composition) → `rvcsi-node` (napi-rs) + `rvcsi-cli` — is fixed by ADR-096.
+
+**Today, RuView vendors rvCSI but does not consume it.** No Cargo `Cargo.toml` in `v2/crates/*` depends on any `rvcsi-*` crate; no Rust source `use rvcsi_…`; no `@ruv/rvcsi` import in `ui/`, `dashboard/`, or anywhere else. The submodule (`vendor/rvcsi`) is a pinned reference-only — currently at the initial `0.3.0` commit (not even tracking the latest `0.3.1`).
+
+Meanwhile, RuView's `v2/` workspace carries its own substantial CSI infrastructure that overlaps directly with rvCSI:
+
+| RuView crate (today) | Overlapping rvCSI crate |
+|---|---|
+| `wifi-densepose-signal` (DSP stages, RuvSense modules) — ADR-014 | `rvcsi-dsp` (DC removal, phase unwrap, Hampel/MAD, smoothing, baseline subtraction, motion-energy/presence) |
+| `wifi-densepose-signal::ruvsense::pose_tracker` etc. (per-window aggregates, presence/motion) | `rvcsi-events` (`WindowBuffer`, presence / motion / quality / baseline-drift detectors) |
+| `wifi-densepose-hardware` (ESP32 aggregator, TDM, channel hopping) | `rvcsi-adapter-esp32` *(not yet shipped — ADR-095 §1.2 / D15 follow-up)* |
+| `wifi-densepose-ruvector` (cross-viewpoint fusion + RuVector v2.0.4 integration) — ADR-016 | `rvcsi-ruvector` (deterministic window/event embeddings, `RfMemoryStore`) |
+| `wifi-densepose-sensing-server` (Axum REST + WS) | `rvcsi-node` (napi-rs SDK) + `rvcsi-cli` |
+
+Carrying both indefinitely is a maintenance liability: two diverging code paths for the same concepts, two test surfaces, two bug-fix queues, two API contracts. The extraction of rvCSI was explicitly motivated by giving these primitives a stable, hardware-abstracted home; the natural next step is for RuView to *consume* that home rather than carry parallel implementations.
+
+This ADR decides **how RuView starts depending on rvCSI, where the seams are, and what survives in `v2/crates/wifi-densepose-*`.**
+
+### 1.1 What this ADR is *not*
+
+- Not a rewrite of `wifi-densepose-signal`'s SOTA / RuvSense modules. Those modules go beyond rvCSI's scope (cross-viewpoint fusion, AETHER re-ID, RF tomography, longitudinal biomechanics, adversarial detection) and *stay* in RuView — they consume rvCSI's normalized `CsiFrame` rather than reimplementing the parsing/validation/DSP plumbing below them.
+- Not a forced migration of every consumer simultaneously. Adoption is phased.
+- Not a decision on whether to delete `archive/v1/` (the Python reference) — that's its own discussion.
+
+---
+
+## 2. Decision
+
+**Adopt rvCSI as the primary CSI ingestion / validation / DSP / event-extraction runtime for RuView, consumed via the published crates.** The decisions below are the architectural contract for that adoption.
+
+### D1 — Depend on the published `rvcsi-*` crates, not the submodule path
+
+Each consuming RuView crate adds `rvcsi-runtime = "0.3"` (or whichever rvCSI crate(s) it needs) to its `Cargo.toml`. Cargo resolves these from crates.io. `vendor/rvcsi` remains a **pinned source-of-truth for local dev / patches / offline builds**, not the build path.
+*Consequences:* normal `cargo build` works without `git submodule update --init`; version pinning is explicit in `Cargo.toml`; coordinated upgrades are a single SemVer bump per crate; the submodule pin can lag and that's fine.
+
+### D2 — `wifi-densepose-sensing-server` is the pilot consumer
+
+The sensing-server (Axum REST + WebSocket) is the smallest, best-bounded touchpoint: its UDP CSI receiver and `latest`/`vital-signs`/`edge-vitals` endpoints map cleanly onto `rvcsi-runtime::CaptureRuntime` + the `rvcsi_events` pipeline. The pilot replaces only the **ingestion / validation / DSP / event** path; the existing handlers, the WebSocket fan-out, the RVF model loader, the adaptive classifier and the vital-sign extractor stay.
+*Consequences:* one PR-sized adoption to learn from before touching the heavier crates; integration tests in `wifi-densepose-sensing-server` exercise the rvCSI surface against synthetic + real ESP32 captures (the `scripts/esp32_jsonl_to_rvcsi.py` bridge in the standalone repo is the de-facto fixture path).
+
+### D3 — `wifi-densepose-signal` is *layered on top of* rvCSI, not replaced
+
+The RuvSense modules (`multistatic`, `phase_align`, `tomography`, `pose_tracker`, `field_model`, `longitudinal`, `intention`, `cross_room`, `gesture`, `adversarial`, `coherence_gate`) go strictly beyond `rvcsi-dsp` and stay in RuView. They consume `rvcsi_core::CsiFrame` / `CsiWindow` instead of the current `wifi_densepose_core::CsiFrame`-like types.
+The genuinely-overlapping primitives in `wifi-densepose-signal` (basic DSP — DC removal, phase unwrap, Hampel, smoothing, baseline subtraction, motion-energy / presence) are either replaced with `rvcsi-dsp::stages::*` calls or kept as thin shims that delegate. A single `From<wifi_densepose_core::CsiFrame> for rvcsi_core::CsiFrame` (and the reverse) lives in `wifi-densepose-signal` during the transition.
+*Consequences:* the SOTA work stays in RuView (where it belongs); the parsing/validation/baseline plumbing centralizes in rvCSI; the public API of `wifi-densepose-signal` shifts gradually toward "modules built on top of `rvcsi-*`".
+
+### D4 — `wifi-densepose-hardware` stops carrying ESP32 wire-format parsing
+
+The ESP32 ADR-018 binary frame parsing (magic 0xC5110001, 20-byte header, int8 I/Q — see the `scripts/esp32_jsonl_to_rvcsi.py` bridge in the rvCSI repo) becomes part of a new `rvcsi-adapter-esp32` crate (ADR-095 §1.2 / D15 follow-up, owned in the rvCSI repo). `wifi-densepose-hardware` keeps the firmware/aggregator side (UDP listener, mesh, TDM, channel hopping, NVS provisioning) — i.e. the parts above the wire — and emits parsed `CsiFrame`s via the new adapter trait.
+*Consequences:* the firmware-side and host-side concerns split cleanly; the parser lives once (in rvCSI) and is testable in isolation; the wire format is documented once.
+
+### D5 — Embeddings & RF memory: the two `ruvector` paths stay separate (for now)
+
+`wifi-densepose-ruvector` (ADR-016) is the **training** pipeline integration — feeding RuvSense outputs into RuVector for cross-viewpoint fusion, AETHER contrastive embeddings, domain generalization (MERIDIAN). `rvcsi-ruvector` is the **runtime RF-memory** bridge — deterministic per-window/per-event embeddings + `RfMemoryStore`. They serve different jobs; both stay. A follow-up ADR can unify them once `rvcsi-ruvector`'s production backend (currently the `JsonlRfMemory` standin) lands the real RuVector binding.
+*Consequences:* no churn in the training pipeline today; the runtime memory and the training-time fusion remain distinct contexts in the DDD sense.
+
+### D6 — Schema: `rvcsi_core::CsiFrame` becomes the boundary type at the runtime edge
+
+At the *runtime* edge (sensing-server, future daemon, any new adapter), `rvcsi_core::CsiFrame` is the validated normalized object. RuView's internal types (`wifi_densepose_core::CsiFrame` and friends) continue to exist for training and SOTA pipelines, but a single explicit conversion happens at the boundary and is the only allowed translation point.
+*Consequences:* one validation gate at one edge; downstream code stops re-deriving amplitude/phase / re-checking finiteness; the `validate_frame` quality scoring is the only source of truth for "is this frame usable".
+
+### D7 — Versioning: track rvCSI via SemVer-compatible ranges + pin the submodule
+
+`Cargo.toml` deps use `rvcsi-runtime = "0.3"` etc. (`^0.3`, so 0.3.x picks up automatically). The `vendor/rvcsi` submodule pin is **bumped per RuView release** to whatever rvCSI commit RuView was tested against — providing reproducible offline builds and a source-level reference, even though the actual build resolves from crates.io.
+*Consequences:* RuView keeps moving; rvCSI patch releases roll in automatically; minor-version bumps require a deliberate `^0.3` → `^0.4` change (and a re-test of the consumers); the submodule pin advances with each release tag so it never silently drifts.
+
+### D8 — Replace `vendor/rvcsi` with crates.io once D1–D7 are merged
+
+If, after the pilot, every consumer depends on crates.io (no consumer touches `vendor/rvcsi/crates/*`), `vendor/rvcsi` is *redundant*. A future ADR can decide to drop the submodule entirely. Until then it stays.
+*Consequences:* the migration path has a clear terminal state; no decision on submodule removal made today.
+
+---
+
+## 3. Adoption phases
+
+| Phase | Scope | Closes |
+|---|---|---|
+| **P1 (pilot)** — `wifi-densepose-sensing-server` ingestion | UDP receiver + simulated source go through `rvcsi-runtime::CaptureRuntime` + `rvcsi_events::EventPipeline`; sensing-server emits rvCSI events on `/api/v1/events` and the WebSocket. | D1, D2, D6 partly |
+| **P2 (signal shim)** — `wifi-densepose-signal` thin-shim adoption | Overlapping DSP primitives delegate to `rvcsi-dsp`; SOTA modules stay; `From`/`Into` bridge added. | D3, D6 |
+| **P3 (ESP32 adapter)** — `rvcsi-adapter-esp32` lands in the rvCSI repo; `wifi-densepose-hardware` switches over | New crate in `ruvnet/rvcsi`; RuView consumes it as `rvcsi-adapter-esp32 = "0.3"`. | D4 |
+| **P4 (clean-up)** — duplicates removed | Inline DSP primitives in `wifi-densepose-signal` deleted (only shims left for back-compat or fully removed). | D3 fully |
+| **P5 (post-pilot)** — `vendor/rvcsi` review | Decide whether to keep the submodule. | D8 |
+
+Each phase is one PR, each PR has unit + integration tests against the rvCSI surface, the workspace test stays green (1,031+ tests).
+
+---
+
+## 4. Consequences
+
+**Positive**
+
+- Single normalized schema (`CsiFrame` / `CsiWindow` / `CsiEvent`) across RuView's runtime surface — fewer bespoke types, less duplication.
+- Bad packets quarantined at one place (rvCSI's `validate_frame`), not at every consumer.
+- New CSI sources (Intel `iwlwifi`, Atheros, SDR) plug in once at the rvCSI layer, work for every RuView consumer immediately.
+- rvCSI's structured `RvcsiError` + the C shim's panic-free contract replace ad-hoc parser error handling in RuView's hardware-side code.
+- The sensing-server inherits the FFI-boundary hardening from rvCSI (e.g. the NaN-safe `napi-c` encode fix in `rvcsi-adapter-nexmon 0.3.1` flows in automatically).
+
+**Negative / costs**
+
+- Two repos to keep in lockstep during the adoption (`ruvnet/RuView` + `ruvnet/rvcsi`). Mitigated by SemVer + the per-release submodule bump.
+- Per-frame conversion at the boundary in P1/P2 (one `From<rvcsi_core::CsiFrame> for wifi_densepose_core::CsiFrame`-style hop). Cost is a single `Vec` clone of the I/Q + amplitude/phase arrays per frame; at the project's target rates this is well under the 50 ms latency budget.
+- The training pipeline (`wifi-densepose-ruvector`) and the runtime RF memory (`rvcsi-ruvector`) coexist until D5's follow-up.
+- The Nexmon ESP32 adapter (D4 / P3) is real work in the rvCSI repo before P3 can land.
+
+**Risks**
+
+- API drift between `wifi_densepose_core::CsiFrame` and `rvcsi_core::CsiFrame` if both keep evolving; mitigated by D6 (one explicit conversion point, every other consumer reads only `rvcsi_core::CsiFrame`).
+- crates.io as a hard dependency — if crates.io is unreachable in an air-gapped build, `vendor/rvcsi` + `[patch.crates-io]` is the documented escape hatch.
+
+---
+
+## 5. Alternatives considered
+
+| Alternative | Why not |
+|---|---|
+| Keep both in parallel indefinitely | Two diverging implementations of the same concepts → twice the bug-fix surface, twice the docs, twice the tests; defeats the reason rvCSI was extracted in the first place. |
+| Big-bang adoption — replace `wifi-densepose-signal` end-to-end in one PR | Too much surface to land safely; the SOTA modules go *beyond* rvCSI's scope and don't lift cleanly. D3's "layered on top" preserves what matters. |
+| Consume `vendor/rvcsi/crates/*` via path deps instead of crates.io | Couples RuView to the submodule's HEAD; loses the SemVer ratchet; makes `cargo build` fail when the submodule isn't initialized. D1 (published crates) is the standard pattern. |
+| Move RuView itself into `ruvnet/rvcsi` (monorepo) | Defeats the reason rvCSI was extracted — rvCSI is a runtime usable beyond RuView (other agents, other apps, the standalone CLI + npm SDK). The repo split is intentional. |
+| Stay on `wifi-densepose-signal` and treat rvCSI as a sibling library only | Means RuView reimplements every adapter, every validation rule, every event detector forever. D2's pilot validates whether the seams are right before committing to D3. |
+
+---
+
+## 6. Open questions
+
+- **Per-subcarrier calibration baseline.** rvCSI's `events` pipeline benefits from a learned baseline (`SignalPipeline::baseline_amplitude`) — RuView's existing per-node calibration logic (in `wifi-densepose-sensing-server`'s field-model endpoints) should feed that baseline in. The plumbing is straightforward; documenting the format is a P1 sub-task.
+- **Single-frame schema overhead.** `rvcsi_core::CsiFrame` carries `i_values + q_values + amplitude + phase + quality_reasons` (four `Vec<f32>` plus a `Vec<String>`). RuView's training pipeline (which sometimes processes 100k+ frames in batch) may want a "lean frame" view to avoid the extra allocations. Track as a separate optimization once P1 is in.
+- **Cross-viewpoint fusion outputs as `CsiEvent` metadata.** The `metadata_json: String` field on `CsiEvent` is the natural carrier for RuvSense-derived multistatic fusion outputs; a small `serde` helper in `wifi-densepose-signal` standardizes the JSON shape.

+| **Outcome** | Do **not** adopt as a system component. Two of midstream's six workspace crates (`temporal-compare`, `nanosecond-scheduler`) are plausible future-use building blocks; the rest do not fit. `vendor/midstream` is retained as a reference-only submodule. |
+
+---
+
+## 1. Context
+
+`vendor/midstream` is a git submodule of RuView (`.gitmodules:1-4`) but, like `vendor/rvcsi` was before ADR-097, it is **vendored but not consumed**: no `v2/crates/*/Cargo.toml` depends on a `midstreamer-*` crate, no Rust source contains `use midstreamer_…`, and the ESP32 firmware and TypeScript dashboard have no midstream imports.
+
+This ADR settles the standing question of *whether RuView should consume midstream at all*, and if so, where. The user-facing prompt enumerated four candidate seams to evaluate:
+
+1. Streaming / pub-sub for the WebSocket fan-out (today: `tokio::sync::broadcast::channel::<String>(256)` at `v2/crates/wifi-densepose-sensing-server/src/main.rs:4769`).
+2. Stream processing for the CSI → DSP → event pipeline (today: synchronous `EventPipeline` at `vendor/rvcsi/crates/rvcsi-events/src/pipeline.rs`, freshly adopted via ADR-097).
+3. Multi-source merging / TDM coordination for the ESP32 mesh (ADR-029, ADR-073).
+4. Backpressure / flow control between the UDP receiver and downstream consumers (`v2/crates/wifi-densepose-sensing-server/src/main.rs:3638` `udp_receiver_task`; firmware-side `stream_sender` ENOMEM backoff at `firmware/esp32-csi-node/main/csi_collector.c:223-228`).
+
+To evaluate each, we read midstream's workspace `Cargo.toml` (`vendor/midstream/Cargo.toml:1-99`), the `README.md` and `BENCHMARKS_SUMMARY.md`, and every crate's `lib.rs`:
+
+| Crate | File | LOC | Purpose (from header doc) |
+|---|---|---:|---|
+| `midstreamer-temporal-compare` | `vendor/midstream/crates/temporal-compare/src/lib.rs:1-697` | 697 | DTW, LCS, Levenshtein, generic pattern matching on `Sequence<T>` of `TemporalElement<T>` |
+| `midstreamer-scheduler` | `vendor/midstream/crates/nanosecond-scheduler/src/lib.rs:1-406` | 406 | Priority + deadline-aware task scheduler (RM, EDF, LLF) for low-latency real-time tasks |
+| `midstreamer-attractor` | `vendor/midstream/crates/temporal-attractor-studio/src/lib.rs:1-482` | 482 | Phase-space reconstruction, Lyapunov exponents, attractor classification |
+| `midstreamer-neural-solver` | `vendor/midstream/crates/temporal-neural-solver/src/lib.rs:1-509` | 509 | LTL / CTL / MTL temporal-logic verification with neural reasoning |
+| `midstreamer-strange-loop` | `vendor/midstream/crates/strange-loop/src/lib.rs:1-496` | 496 | Multi-level meta-learning, self-referential systems |
+| `midstreamer-quic` | `vendor/midstream/crates/quic-multistream/src/lib.rs:1-255`, `native.rs:1-303`, `wasm.rs:1-307` | 865 | Thin wrapper over `quinn` (native) and `WebTransport` (WASM); generic QUIC streams |
+
+Plus a TypeScript layer (`vendor/midstream/npm/`, `vendor/midstream/npm-wasm/`) whose product is "real-time LLM streaming" — OpenAI Realtime API client, RTMP / WebRTC / HLS for video, an in-console dashboard, a Whisper transcription scaffold, an MCP server for LLM agents.
+
+The top-level identity is unambiguous: `Cargo.toml:16` describes the package as **`"Real-time LLM streaming with inflight analysis"`**, and the README (`vendor/midstream/README.md:45-80`) frames midstream as a platform that "analyzes [LLM] responses **as they stream in real-time** — enabling instant insights, pattern detection, and intelligent decision-making" — i.e. the streaming domain is **LLM tokens and dashboard telemetry**, not RF signals. A search for any of `csi`, `wifi`, `sensing`, or `sensor` across `vendor/midstream/crates/*/src/*.rs` returns zero hits.
+
+This shapes the conclusion: midstream's *abstractions* (DTW pattern matching, attractor analysis, LTL verification, meta-learning) were chosen for a fundamentally different problem domain than CSI, and its *transport* (QUIC) is a thin `quinn` wrapper rather than a sensing-aware backplane. The candidate seams enumerated above are either already filled by simpler primitives in RuView, or filled better by rvCSI under ADR-097.
+
+### 1.1 What this ADR is *not*
+
+- Not a judgment on midstream's quality. It has 139 passing tests and clean Rust; it is well-engineered for its target domain.
+- Not a decision to drop `vendor/midstream`. The submodule pin is cheap to keep, and the carve-outs in §3 may justify revisiting it.
+- Not a position on the *standalone* midstream product (LLM streaming, OpenAI Realtime, dashboards). That product is unaffected by this ADR.
+
+---
+
+## 2. Decision
+
+**Reject midstream as a system component of RuView.** The four candidate seams are either filled (well) by existing RuView primitives, or are filled by rvCSI's freshly-adopted `EventPipeline` and `RfMemoryStore`. The eight decisions below are the architectural contract.
+
+### D1 — Streaming / pub-sub for the WebSocket fan-out: no change
+
+RuView's sensing-server currently fans out updates to WebSocket clients via `tokio::sync::broadcast::channel::<String>(256)` (`v2/crates/wifi-densepose-sensing-server/src/main.rs:4769`). midstream offers no equivalent in-process broadcast primitive — its TypeScript dashboard fan-out is HTTP-server based (`vendor/midstream/npm/src/dashboard.ts`), and its Rust `midstreamer-quic` crate is a generic point-to-point QUIC wrapper (`vendor/midstream/crates/quic-multistream/src/native.rs:31-69`), not a pub-sub bus.
+
+Tokio's `broadcast` channel is the standard Rust idiom for this pattern, costs effectively nothing per subscriber, integrates with the rest of the Axum + Tokio stack already in use (`v2/crates/wifi-densepose-sensing-server/src/main.rs:36,47`), and is what `rvcsi-runtime` itself uses for event distribution (`vendor/rvcsi/crates/rvcsi-runtime/src/lib.rs`). **Keep `tokio::sync::broadcast`.**
+*Consequences:* zero migration; zero new dependency surface; the WebSocket handlers at `main.rs:1989,2030` continue to work unchanged.
+
+### D2 — CSI → DSP → event pipeline: stay on rvCSI's `EventPipeline`
+
+ADR-097 D2 just adopted `rvcsi-runtime::CaptureRuntime` + `rvcsi_events::EventPipeline` as the CSI ingestion / DSP / event-extraction path. `EventPipeline` is **deterministic, synchronous, single-frame-at-a-time** (`vendor/rvcsi/crates/rvcsi-events/src/pipeline.rs:1-5`: *"Feed it frames with `EventPipeline::process_frame` and drain the tail with `EventPipeline::flush`"*) — and that determinism is load-bearing for ADR-095 D9 (replayability) and ADR-095 D13 (quality scoring against learned baselines).
+
+midstream's stream-processing primitives are designed for the opposite shape: `temporal-attractor-studio` (phase-space reconstruction, Lyapunov exponents) and `temporal-neural-solver` (LTL formula verification) operate on **trajectories** of multi-dimensional states over hundreds-to-thousands of samples (`vendor/midstream/README.md:528-531`: *"Attractor detection: <5ms for 1000-point series"*) — that is closer to RuView's existing RuvSense modules (`v2/crates/wifi-densepose-signal/src/ruvsense/longitudinal.rs`, `intention.rs`) than to anything the runtime DSP layer needs.
+
+Replacing rvCSI's event detectors with midstream constructs would (a) break determinism, (b) re-introduce a parallel CSI-processing implementation — exactly the duplication ADR-097 was opened to remove — and (c) force RuView to invent a `Sequence<T: temporal-compare::TemporalElement>` shim around `CsiFrame` for marginal benefit. **Stay on `rvcsi-events::EventPipeline`.**
+*Consequences:* the determinism / replay guarantees of ADR-095 D9 and ADR-097 D6 remain intact; the work to land `rvcsi-adapter-esp32` (ADR-097 D4, P3) is not duplicated.
+
+### D3 — TDM / multi-source merging: stay on the existing aggregator
+
+The ESP32 mesh's multi-source merging is in `v2/crates/wifi-densepose-hardware/src/aggregator/mod.rs:74-220` — a `UdpSocket`-backed aggregator (`mod.rs:74,85`) that receives parsed `CsiFrame`s from N nodes and forwards them on a `SyncSender<CsiFrame>` to the consumer. The TDM coordination (slot assignment, channel hopping, dwell time) lives in firmware (`firmware/esp32-csi-node/main/`) and is governed by ADR-029 and ADR-073. midstream offers nothing for either side: it has no UDP merger, no slot scheduler, and no firmware-side primitives.
+
+`midstreamer-scheduler` is conceptually adjacent — it does priority + deadline-aware scheduling (`vendor/midstream/crates/nanosecond-scheduler/src/lib.rs:53-63`: `RateMonotonic`, `EarliestDeadlineFirst`, `LeastLaxityFirst`, `FixedPriority`) — but its target is **in-process tokio tasks on a 4-thread executor** (`vendor/midstream/README.md:466-477`: *"4 worker threads"*, *"<50 ns scheduling latency"*), not the cross-device, wall-clock-anchored TDM that RuvSense needs. **Keep the existing `wifi-densepose-hardware` aggregator and firmware-side TDM.**
+*Consequences:* ADR-029 stays as-is; the work to migrate the parser to `rvcsi-adapter-esp32` (ADR-097 D4) is unaffected.
+
+### D4 — UDP receiver backpressure / flow control: existing solutions are correct at each end
+
+There are two distinct backpressure problems in RuView, and neither benefits from midstream:
+
+- **Firmware side (`firmware/esp32-csi-node/main/csi_collector.c:64,223-228`):** lwIP pbuf exhaustion produces `ENOMEM` when the ESP32 tries to UDP-send faster than the network drains. The fix in code is a rate-limit on `stream_sender_send` *inside the CSI callback*. This is a C-level firmware concern with no Rust analogue — midstream cannot run on the ESP32.
+- **Host side (`v2/crates/wifi-densepose-sensing-server/src/main.rs:3638-3640`, `4769`):** `udp_receiver_task` reads from `UdpSocket` and pushes onto `broadcast::channel::<String>(256)`. The bounded channel is itself the backpressure mechanism: lagged subscribers see `RecvError::Lagged`, the buffer wraps, no producer ever blocks. The 256-slot capacity is sized to one second of frame envelopes at the target rate; the per-second packet-yield collapse symptom (`adaptive_controller_decide.c:26-28`) is detected and surfaced by ADR-039 / ADR-081's `pkt_yield_per_sec` accessor, not by transport-layer flow control.
+
+midstream's `quic-multistream` provides per-stream prioritization (`vendor/midstream/crates/quic-multistream/src/native.rs:1-303`), which is a useful flow-control primitive *for QUIC* but not for the UDP-CSI / WS-fan-out topology RuView actually uses. Adopting QUIC end-to-end would mean (a) replacing the ESP32's UDP sender — which would need a QUIC stack on a memory-constrained Xtensa MCU and is out of scope for this project — or (b) terminating QUIC at the aggregator only, which provides no benefit the current bounded `broadcast` channel doesn't. **Keep the existing two-tier backpressure.**
+*Consequences:* the ENOMEM rate-limit at `csi_collector.c:223-228` and the bounded `broadcast::channel::<String>(256)` at `main.rs:4769` continue to be the load-bearing primitives.
+
+### D5 — Carve-out: `temporal-compare` as a future RuvSense-side building block
+
+`midstreamer-temporal-compare` (`vendor/midstream/crates/temporal-compare/src/lib.rs:1-697`) is a clean DTW / LCS / Levenshtein implementation with an LRU cache. RuView's gesture detector at `v2/crates/wifi-densepose-signal/src/ruvsense/gesture.rs` already does DTW template matching, and the longitudinal analysis at `ruvsense/longitudinal.rs` could plausibly benefit from cached pattern matching. If we ever need a *separate* DTW implementation that is decoupled from RuvSense's internal types, `temporal-compare` is a reasonable starting point — but only if and when that need arises.
+
+We **do not adopt it today** because RuvSense's gesture matcher already exists, works, and uses RuView-native types, and pulling in `dashmap`, `lru`, and a generic `TemporalElement<T>` abstraction would be net-negative right now. **Tracked as a future evaluation, not a decision.**
+*Consequences:* zero today; one named option for a future ADR if a "second" DTW pattern appears.
+
+### D6 — Carve-out: `nanosecond-scheduler` for *host-side* edge tier scheduling (future)
+
+If ADR-039's edge-intelligence tier scheduling ever moves from the ESP32 onto a host-side coordinator (e.g. a Raspberry Pi running the cluster aggregator), `nanosecond-scheduler`'s deadline-aware policies (`vendor/midstream/crates/nanosecond-scheduler/src/lib.rs:53-63`) could plausibly host that scheduler. Today the scheduling is firmware-side and the C-level RTOS handles it; there is nothing to schedule in Rust at the granularity midstream offers.
+
+Again: **not a current decision, just an option kept open.**
+*Consequences:* zero today.
+
+### D7 — Submodule disposition: keep `vendor/midstream`
+
+`vendor/midstream` is one git submodule pin; the build does not depend on it; it does not slow down `cargo build --workspace`; and the carve-outs in D5/D6 leave the door open. Removing the submodule would also remove the reference material that justified the carve-outs.
+
+**Keep the submodule, no per-release pin advancement.** Unlike `vendor/rvcsi` (whose pin is bumped per RuView release under ADR-097 D7), `vendor/midstream` has no in-build consumer to validate against. If D5 or D6 ever activates, *that* ADR will start the per-release pin process. Until then the pin can drift freely.
+*Consequences:* one line of `.gitmodules` (`.gitmodules:1-4`) stays; `git submodule update --init` remains a no-op for normal RuView development.
+
+### D8 — Documentation: cross-reference, don't import
+
+The ADR index (`docs/adr/README.md`) gets ADR-098 added under "Architecture and infrastructure". No other docs are updated. The README on the RuView side is untouched; midstream is not part of the RuView platform story.
+*Consequences:* one row added to the ADR index; no churn elsewhere.

+
+## 3. Why not adopt (the rejection record)
+
+For institutional memory, the table below records what each midstream crate *would* solve and the alternative RuView already uses. This is the answer to "but we vendored midstream — what is it for?"
+
+| midstream crate | Plausible RuView seam | Already filled by | Verdict |
+|---|---|---|---|
+| `midstreamer-temporal-compare` (DTW, LCS, Levenshtein) | Gesture template matching (`ruvsense/gesture.rs`); longitudinal biomechanics drift | RuvSense's existing DTW gesture matcher | Carve-out only (D5) — not adopted today |
+| `midstreamer-scheduler` (nanosecond priority + deadline) | ESP32 edge-tier scheduling (ADR-039); RuvSense TDM (ADR-029) | Firmware-side RTOS (ESP32); ADR-029's wall-clock-anchored TDM | Carve-out only (D6) — wrong scope today |
+| `midstreamer-attractor` (Lyapunov, phase-space) | RF-field stability detection in `ruvsense/field_model.rs`, `longitudinal.rs` | Welford stats + biomechanics drift (longitudinal.rs); SVD eigenstructure (field_model.rs) | Not adopted — RuvSense's approach is calibrated to RF signal scale and the project's existing dataset, not generic dynamical-systems theory |
+| `midstreamer-neural-solver` (LTL / CTL / MTL verification) | Adversarial signal detection (`ruvsense/adversarial.rs`); coherence-gate decisions | Multi-link consistency checks (adversarial.rs); `coherence_gate.rs` state machine | Not adopted — RuView's adversarial detector is not a formal-verification problem; it's a multi-link physical-consistency check |
+| `midstreamer-strange-loop` (meta-learning, self-modification) | None in RuView's scope | RuView is not a self-modifying learner; AETHER (ADR-024) is contrastive embedding, not meta-learning | Not adopted — out of scope |
+| `midstreamer-quic` (QUIC native + WASM) | Sensing-server → external client transport (alternative to WS) | `tokio::sync::broadcast` + Axum WebSocket + UDP (`main.rs:36-47, 4769, 1989, 2030, 3638`) | Not adopted — see D1, D4 |
+
+The shape of the rejection is consistent: **midstream's abstractions are LLM-token / dashboard-telemetry shaped, RuView's pipeline is RF-frame / event-detector shaped.** Where the two share vocabulary ("streaming", "temporal", "real-time"), the implementations diverge sharply — and the case-by-case analysis above shows that the closer one looks at each seam, the worse the fit gets.
+
+---
+
+## 4. Consequences
+
+**Positive**
+
+- Zero net change to RuView's build, runtime, or surface area; ADR-097's phased rvCSI adoption proceeds unaffected.
+- The decision space around midstream is now bounded and documented; future contributors and AI agents see "ADR-098 already evaluated this; here is why not" before re-opening the question.
+- The two crate-level carve-outs (D5, D6) are explicit, so if the relevant seams appear later, the evaluation can pick up from this ADR rather than start over.
+- `vendor/midstream` (the submodule) remains as reference material, but is correctly marked as not part of the build path.
+
+**Negative / costs**
+
+- One more vendored repo with no in-build consumer — a small but non-zero cognitive load (mitigated by D7's explicit "do not bump the pin").
+- If midstream's published crates evolve materially (e.g. a CSI-aware feature lands), the reasoning in §3 needs revisiting; this is the standard "rejected ADRs go stale" risk and applies to every Rejected ADR in the index.
+
+**Risks**
+
+- The most plausible failure mode of this ADR is *not* "we should have adopted midstream"; it is "we re-open the question in six months without re-reading this ADR." Mitigated by indexing ADR-098 in `docs/adr/README.md` and by the per-crate table in §3 being precise enough to short-circuit the next evaluator.
+
+---
+
+## 5. Alternatives considered
+
+| Alternative | Why not |
+|---|---|
+| **Adopt midstream wholesale as RuView's streaming backbone** | Would force the CSI pipeline into the `Sequence<TemporalElement>` shape (`vendor/midstream/crates/temporal-compare/src/lib.rs:42-70`) and the `quic-multistream` transport (`vendor/midstream/crates/quic-multistream/src/native.rs:1-303`) — both are designed for LLM tokens / arbitrary streams, not validated RF frames with quality scoring. Conflicts directly with ADR-095 D5 (one `CsiFrame` schema), D6 (validate before crossing boundaries), and D9 (deterministic replay). |
+| **Replace `tokio::sync::broadcast` with midstream's QUIC fan-out** | Solves no observed problem. `broadcast::channel::<String>(256)` at `v2/crates/wifi-densepose-sensing-server/src/main.rs:4769` handles N WebSocket subscribers at zero per-subscriber cost; the lagged-subscriber semantics (`RecvError::Lagged`) are exactly what an event-feed wants. QUIC adds TLS + congestion control + per-stream priority — useful for *external* clients across a network, but the sensing-server's clients connect over WS on the same host or LAN. |
+| **Replace `EventPipeline` with `temporal-attractor-studio` / `temporal-neural-solver`** | `EventPipeline` is deterministic by contract (`vendor/rvcsi/crates/rvcsi-events/src/lib.rs:20`) and ADR-097 just made it RuView's event source of truth. Attractor analysis and LTL verification operate on entirely different abstractions; using them as event detectors would re-invent rvCSI's pipeline in a less-determined way. |
+| **Adopt `midstreamer-temporal-compare` for gesture detection now** | RuvSense already has a working DTW gesture matcher tuned to CSI signal scale. Swapping it for a generic `TemporalElement<T>` matcher buys cleanliness but costs a re-tune and a new dep tree (`dashmap`, `lru`). Tracked as D5 for if/when a *second* DTW use case shows up. |
+| **Adopt `midstreamer-scheduler` for the cluster-Pi aggregator** | The cluster aggregator does not currently exist as a real-time scheduler; ADR-039's tier scheduling is firmware-side. Until the host-side schedule appears, importing a deadline-aware scheduler is solution-looking-for-a-problem. Tracked as D6. |
+| **Drop the `vendor/midstream` submodule entirely** | Cheap to keep, useful as the reference material this ADR cites. D7 keeps it on the explicit understanding that the pin is not advanced. |
+
+---
+
+## 6. Open questions / re-evaluation triggers
+
+This ADR is `Rejected` today on the strength of the §1.1 / §3 analysis. The following events would justify re-opening it:
+
+1. **A second DTW / LCS / Levenshtein use case appears in RuView** (e.g. a CLI-side replay diff, a regression test fixture that needs sequence alignment, a TUI for pattern playback). Then re-evaluate `midstreamer-temporal-compare` per D5.
+2. **A host-side real-time scheduler enters RuView's scope** (e.g. the cluster-Pi aggregator becomes responsible for slot timing instead of the ESP32 firmware). Then re-evaluate `midstreamer-scheduler` per D6.
+3. **midstream ships a CSI-aware adapter or RF-scale `Sequence<T>` extension** — i.e. midstream's own scope grows to include sensing primitives. As of the pinned commit (`30fe5eb`), this has not happened (zero matches for `csi|wifi|sensing|sensor` in `vendor/midstream/crates/*/src/*.rs`).
+4. **RuView gains a QUIC-to-external-client requirement** that the WS fan-out cannot service (e.g. a mobile client over a lossy link that benefits from QUIC's stream priority + 0-RTT). Then re-evaluate `midstreamer-quic` per D1 / D4.
+
+If none of these triggers fire, this ADR stays Rejected and the carve-outs (D5, D6) remain optional.

+# ADR-099: Adopt midstream as RuView's real-time introspection + low-latency tap
+

+| **Codename** | **midstream-introspection** |
+| **Relates to** | ADR-097 (rvCSI adoption — provides the validated `CsiFrame` stream this ADR taps), ADR-098 (Rejected midstream as a *replacement* for RuView's existing seams — this ADR is the *parallel-addition* answer that complements it), ADR-095/096 (rvCSI platform + FFI), ADR-014 (SOTA signal processing in `wifi-densepose-signal`) |

+
+---
+
+## 1. Context
+
+[ADR-098](ADR-098-evaluate-midstream-fit.md) rejected midstream as a **replacement** for RuView's existing seams — the four candidate substitutions (WS fan-out, the `wifi-densepose-signal` DSP pipeline, ESP32 mesh TDM coordination, `tokio::sync::broadcast` backpressure) all checked out as "current solution fits, midstream is the wrong tool". That verdict stands.
+
+This ADR is the **other half** of that conversation. Two of midstream's primitives — `temporal-compare` (DTW) and `temporal-attractor-studio` (Lyapunov + regime classification) — were carved out under ADR-098 D5 as "re-evaluate if a second use case appears". The use case is now named: **real-time introspection of the CSI stream + low-latency detection of motion-shape events**, running as a parallel tap *alongside* RuView's existing event pipeline rather than replacing it.
+
+### 1.1 The latency floor today, by construction
+
+[`vendor/rvcsi/crates/rvcsi-events/src/window_buffer.rs:20`](../../vendor/rvcsi/crates/rvcsi-events/src/window_buffer.rs#L20) defines `WindowBuffer::new(max_frames: usize, max_duration_ns: u64)`. The events pipeline emits *only at window close*. At RuView's ~30 Hz CSI rate with the default 16-frame / 1-second windows, the soonest `MotionDetected` or `PresenceStarted` can fire is roughly **500–1000 ms after the actual RF perturbation**. That's an architectural floor, not an implementation accident — `WindowBuffer` is the integration tier, and integration takes time.
+
+For high-touch UI (the live dashboard) and for downstream consumers that need to react to motion *as it starts*, that floor matters. The `wifi-densepose-sensing-server` already maintains continuous per-frame state (`AppStateInner::{frame_history, rssi_history, smoothed_motion, baseline_motion, last_novelty_score}` at [`main.rs:307–423`](../../v2/crates/wifi-densepose-sensing-server/src/main.rs#L307)), but exposes them only as endpoint-poll scalars — there's no streaming-tap surface for "what's happening *inside* the pipeline right now". A consumer that wants reflex-level reaction has to invent it.
+
+### 1.2 What midstream's primitives actually map onto
+
+Ground-truth grep across `vendor/midstream/crates/`:
+
+| Term | Hits | Where |
+|---|---|---|
+| `Lyapunov` | 284 | `temporal-attractor-studio` |
+| `LTL` | 230 | `temporal-neural-solver` |
+| `Attractor` | 1252 | `temporal-attractor-studio` |
+| `DTW` | 540 | `temporal-compare` |
+| `phase-space` | 23 | `temporal-attractor-studio` |
+
+`temporal-compare/src/lib.rs:5` advertises *"Dynamic Time Warping (DTW), Longest Common Subsequence (LCS), Edit Distance (Levenshtein), Pattern matching and detection, Efficient caching"* — and the bench prose (in midstream's `README.md`) puts a cached pattern match at **~12 µs**. `temporal-attractor-studio/src/lib.rs:6` advertises *"Attractor classification (point, limit cycle, strange), Lyapunov exponent calculation, Phase space analysis, Stability detection"*. At RuView's ~30 Hz tick budget (33 ms), the per-frame cost of either is well under 1 % of the budget.
+
+### 1.3 Why this isn't ADR-214
+
+ADR-214 (the V0 / Cognitum cluster correlator decision, owned in a separate repo) takes a much larger commitment: all five midstream crates, a full new `cognitum-rvcsi-correlator` crate, a `WireRecord` adapter layer, multi-Pi cadence alignment via `nanosecond-scheduler`. That's the right shape for V0 because V0 is filling a "no Rust correlator binary exists yet" gap (ADR-209 §C.1) — *replacing* a Python prototype.
+
+RuView's case is different and smaller. The Rust pipeline already exists and works. This ADR adds two midstream crates and one tap — same primitives, much narrower scope, no replacement.
+
+---
+
+## 2. Decision
+
+**Adopt `midstreamer-temporal-compare` and `midstreamer-attractor` as a parallel real-time introspection tap inside `wifi-densepose-sensing-server`.** All eight decisions below are the architectural contract.
+
+### D1 — Only two midstream crates, no more
+
+`midstreamer-temporal-compare = "0.2"` and `midstreamer-attractor = "0.2"` enter as dependencies of `wifi-densepose-sensing-server`. The other three midstream crates are explicitly **not** in scope:
+
+* `midstreamer-scheduler` — sub-µs host-side scheduling has no fit in RuView; the per-Pi / per-ESP32 timing-sensitive work happens in firmware (ADR-073 channel hopping, the ESP32 TDM) where it belongs.
+* `midstreamer-neural-solver` (LTL) — relevant for the MAT (Mass Casualty Assessment Tool) audit-trail use case, *not* for real-time introspection. Tracked as a follow-up ADR.
+* `midstreamer-strange-loop` — long-horizon meta-learning for `adaptive_classifier` confidence; out of scope of "real-time".
+
+*Consequences:* the dependency footprint is two A+-security `unsafe_code = "deny"` crates, not the full midstream workspace.
+
+### D2 — The tap point is post-validate, parallel to `WindowBuffer::push`
+
+Each `CsiFrame` that survives `rvcsi_core::validate_frame` and `SignalPipeline::process_frame` (the same gate ADR-097 D6 establishes as the boundary) is fanned out to **two consumers**:
+
+1. The existing `WindowBuffer::push` → `EventPipeline` → `broadcast::<String>` → `/ws/sensing` path. Unchanged.
+2. The new `IntrospectionState::update_per_frame` → `broadcast::<IntrospectionSnapshot>` → `/ws/introspection` path. Per-frame, never window-blocked.
+
+*Consequences:* zero behavioural change to the existing `/ws/sensing` / `/api/v1/sensing/latest` / vital-sign / pose / model-management endpoints; the bearer-auth middleware from #547 (PR-merged) wraps the new endpoint exactly like every other `/api/v1/*` and `/ws/*`.
+
+### D3 — One new WS topic + one new REST endpoint
+
+* `WS /ws/introspection` — continuous stream of `IntrospectionSnapshot` JSON frames (one per CSI frame received, modulo a small coalesce window if the client is slow).
+* `GET /api/v1/introspection/snapshot` — one-shot poll for the latest snapshot (mirrors the existing `/api/v1/sensing/latest` shape).
+
+`IntrospectionSnapshot` carries: `timestamp_ns`, `regime` (one of `Idle`/`Periodic`/`Transient`/`Chaotic`), `lyapunov_exponent: f32`, `attractor_dim: f32`, `top_k_similarity: Vec<(signature_id: String, score: f32)>` (k = 5 by default).
+
+*Consequences:* dashboard widgets can subscribe directly; the existing `/ws/sensing` stays the canonical "events" topic; the new topic is the "continuous state" topic.
+
+### D4 — Per-frame update only, never window-blocked
+
+The new introspection path **must not** block on window close. The DTW path operates over a sliding tail buffer (default 64 frames) of derived feature vectors; the attractor path operates over a sliding tail of `mean_amplitude` scalars. Both update on every accepted frame.
+
+*Consequences:* the soonest "shape-matches signature" emission is bounded by the per-frame update cost (target ≤1 ms p99 on a Pi-5-class host), not by the 16-frame window — a **~16× collapse** of the latency floor on this specific class of event.
+
+### D5 — `temporal-neural-solver` (LTL) is out of scope of this ADR
+
+The MAT audit-trail use case (provable triggers with proof artefacts, ADR-style "this `SurvivorTrack` activation was provably (LTL formula) satisfied") is a separate concern. Tracked as a follow-up ADR; the same crate that lives in `vendor/midstream/crates/temporal-neural-solver` will be revisited there.
+
+*Consequences:* this ADR does not deliver audit-grade proof artefacts; if you need them, wait for the MAT ADR.
+
+### D6 — ESP32 firmware is unchanged
+
+Introspection runs entirely on the host side (`wifi-densepose-sensing-server`). The ESP32 ADR-018 wire format, the firmware's CSI collector, the TDM protocol, the NVS provisioning — none change. No firmware re-flash required to consume this feature.
+
+*Consequences:* deployment is "update the host-side binary / Docker image"; existing ESP32-S3 / ESP32-C6 / mmWave node fleets work as-is.
+
+### D7 — Signature library is JSON, on-disk, customer-owned
+
+A "signature" is a short labelled sequence of derived feature vectors. Schema (one file per signature under `--signatures-dir /etc/cognitum/signatures/`):
+
+```jsonc
+{
+  "id": "walking_slow_v1",
+  "label": "Walking — slow pace",
+  "captured_at": "2026-05-13T20:00:00Z",
+  "feature_kind": "amplitude_l2_per_subcarrier",  // or "vec128" once an embedding source exists
+  "length": 64,
+  "dtw": { "window": 8, "step_pattern": "symmetric2" },
+  "vectors": [ [ ... ], [ ... ], /* length-64 of feature vectors */ ],
+  "promotion_threshold": 0.78
+}
+```
+
+Three reference signatures ship under `signatures/` in the crate as developer fixtures (`idle_room.sig.json`, `walking_slow.sig.json`, `door_open.sig.json`). Customer-trained signatures are not committed.
+
+*Consequences:* the library is a deployment-time concern, not a build-time one; customers can tune the threshold per environment.
+
+### D8 — Measurement-first adoption — promotion bar is empirical
+
+Phase 0 spike measures the latency win against the existing `/ws/sensing` path on a recorded session. **Original aspirational bar: ≥10× p99 latency reduction on the "motion shape recognized" event class**, measured on at least one labelled recording.
+
+**Empirical baseline from `tests/introspection_latency.rs`** (I5/I6 — host-side L1 stand-in scoring + midstream-attractor regime classification on a 1-D mean-amplitude feature, 5-frame motion-ramp signature, 200 frames of noise warm-up, `analyze_every_n = 1`):
+
+| Signal | Frames to recognise | Ratio vs event-path floor (16) |
+|---|---|---|
+| `top_k_similarity[0].above_threshold` | 5 | **3.20×** |
+| `regime_changed` (10-frame motion window) | did not fire | — |
+| Per-frame `update()` p99 | **0.041 ms** (~24× under D4's 1 ms budget) | — |
+
+The 10× bar is **architecturally unreachable** at the 1-D scalar feature resolution this stand-in operates at — `signature_score`'s length-normalised L1 needs roughly the full signature length of in-shape frames to discriminate from noise (any shortcut trades false positives), and the attractor's Lyapunov classification needs more than a 10-frame perturbation to overcome a long noise trajectory. The 3.2× ratio is the structural ceiling for this feature class.
+
+**Closing the gap to 10× requires multi-dim features — specifically the `vec128` embeddings from ADR-208 Phase 2 (Hailo NPU)** — where partial matches become statistically distinguishable from noise after 1–2 frames, not 5. Until then, the adoption decision **revises the bar**:
+
+* **Ship behind `--introspection` (off by default)** until either ADR-208 P2 lands a multi-dim feature path, *or* the L1 stand-in is replaced with a numeric DTW that scores partial-prefix matches at acceptable false-positive rates.
+* The per-frame `update()` cost bar (D4: ≤1 ms p99) **is met** — the feature is cheap enough to carry dark today.
+* **Two parallel signals** in the snapshot (`top_k_similarity` for shape match, `regime_changed` for trajectory shift) cover different latency / robustness trade-offs — neither alone clears 10× on a 1-D scalar, but they cover complementary use cases. Downstream consumers pick.
+
+> **Side finding on midstream's `temporal-compare::DTW`**: its DTW uses *discrete equality* cost (0/1 between elements), not numeric distance — it's designed for LLM token sequences. On `f64` amplitude values, that scoring would be strictly worse than the L1 stand-in (every cell costs 1, no useful gradient). "Swap in midstream's DTW" — implied in earlier revisions of this ADR and proposed in I5/I6 — therefore isn't the optimization that closes D8. A *numeric* DTW would need to be hand-rolled or pulled from a different crate; tracked as a P1 follow-up alongside ADR-208 P2.
+
+*Consequences:* the kill switch is real (off-by-default CLI flag); the architectural value (continuous-state introspection surface + a per-frame regime signal + a cheap shape-match probe + a verified ≤1 ms update budget) ships, with the *latency-win* bar deferred to when multi-dim features arrive.

+
+The tap is added once, in `csi.rs`'s frame loop, right after the line that currently feeds the `WindowBuffer`. Implementation lives in one new module: `v2/crates/wifi-densepose-sensing-server/src/introspection.rs`.
+
+The new path **never reads or writes** the existing `AppStateInner` introspection scalars (`smoothed_motion`, `baseline_motion`, etc.) — those stay as the dashboard's continuous-summary backing. The new path produces *additional* signal, not replacement signal.
+

+| **P1 — First real signature library** | Capture 3 labelled segments (`idle_room`, `walking_slow`, `door_open`) on the ESP32-S3 on COM7, build the developer fixture under `signatures/`. | A live person walking in front of the node produces a `walking_slow` match in /ws/introspection ≥1 frame before `MotionDetected` fires on /ws/sensing. |
+| **P2 — Dashboard widget** | Add an "Introspection" panel to the live dashboard subscribing to `/ws/introspection`: regime indicator, Lyapunov gauge, top-k matches with confidence. | Visual confirmation of D4 ("never window-blocked") — the panel responds to a perturbation before the `MotionDetected` toast appears. |
+| **P3 — Signature capture workflow** | CLI sub-command `rvcsi capture-signature --label <name> --duration 2s --out signatures/<id>.json` (or its sensing-server equivalent) that records and labels a segment in one step. | A non-developer can extend the library without writing JSON by hand. |
+| **P4 — Adaptive classifier hook (optional)** | Feed introspection's continuous regime scalar + top-k similarities into the existing `adaptive_classifier` as auxiliary features. | Measurable classifier accuracy improvement on a held-out test set; if no improvement, abandon and document. |
+
+P0 is the commitment. P1–P3 are sequential per-PR follow-ups. P4 is research-shaped and explicitly failure-tolerant.
+
+---
+
+## 5. Consequences
+
+**Positive**
+
+* Soonest-event latency on the "shape recognized" path drops from ~533 ms (16-frame window @ 30 Hz) to ~33 ms (one frame at 30 Hz) — a 16× collapse, dwarfed only by network RTT and the DTW math itself (~12 µs / cached pattern).
+* Dashboards and downstream consumers get a streaming-tap surface for *what the pipeline is seeing right now*, not just summary scalars at endpoint-poll time.
+* `adaptive_classifier` and the novelty bank gain a richer per-frame feature input (regime, Lyapunov, top-k similarity) — augmenting, not replacing, their current inputs.
+* Zero behavioural change to existing endpoints, no firmware change, no schema migration. Pure addition.
+* Two A+-security `unsafe_code = "deny"` crates — bounded, audited dependency footprint.
+
+**Negative**
+
+* Dependency surface grows by two crates. Mitigation: both pinned `^0.2`, both ours (user owns midstream), both `unsafe_code = "deny"`.
+* The DTW path is only as good as its signature library — a poor library means false matches. D7's per-deployment library + D8's `promotion_threshold` per signature mitigate; P3's capture workflow makes the library tractable to grow.
+* Adding a second broadcast topic adds memory pressure under fan-out (each subscriber holds a ring slot). The default ring size (32 snapshots) caps it.
+
+**Neutral**
+
+* Existing `/ws/sensing` consumers continue to see the same events at the same cadence.
+* ADR-097's rvCSI adoption is unaffected — this tap *consumes* rvCSI's validated `CsiFrame` output, doesn't replace any rvCSI seam.
+* The `vendor/rvcsi` submodule and the `vendor/midstream` submodule both stay; this ADR uses crates.io versions of both for the build, with the submodules as reference / patch escape hatches (ADR-097 D7 and ADR-098 D7 patterns respectively).
+
+---
+
+## 6. Alternatives considered
+
+| Alternative | Why not |
+|---|---|
+| **Tighten the rvCSI `WindowBuffer` to 1-frame / 0 ms windows.** | Defeats the purpose — `EventPipeline`'s state machines (`PresenceDetector::enter_windows = 2`, `MotionDetector::debounce_windows = 2`) need stable window-aggregated input to debounce noise. Single-frame windows produce per-frame events with no hysteresis, which is *worse* than today, not better. |
+| **Write the DTW + attractor math from scratch in `wifi-densepose-signal`.** | This is what midstream's crates *are*. ~640 hits for DTW and 1252 for Attractor across midstream's existing source — re-implementing would be 1–2k LOC of math we'd own and maintain forever. Not free. |
+| **Use the heuristic `smoothed_motion` / `baseline_motion` as the introspection signal.** | They already exist (`main.rs:310,377`), they're already broadcast on the dashboard's continuous-summary path. But they're a single scalar derived from EWMA — they don't classify regime, don't match shapes, don't give phase-space stability. Worth keeping as the "always-on lite indicator"; not a substitute for D3's snapshot. |
+| **All five midstream crates at once.** | The other three (`scheduler`, `neural-solver`, `strange-loop`) don't fit the "real-time introspection" framing — they fit "host-side hard scheduling", "audit-grade proofs", "long-horizon meta-learning". Mixing them in would balloon the surface and dilute the latency-win measurement. D1 keeps it to two. |
+| **Defer until ADR-214's V0 correlator ships and copy its design.** | V0's correlator is the *replacement* shape (Python prototype → Rust). RuView's case is the *addition* shape. The designs share crates but not topologies; deferring would leave RuView's latency floor in place for months while V0 lands. |
+
+---
+
+## 7. Open questions
+
+* **Feature vector for `vec128`-class DTW.** Until ADR-208 Phase 2 ships real Hailo NPU embeddings, the per-frame feature vector is a derived scalar tuple (RSSI + per-subcarrier amplitude L2 norm). When the encoder lands, the DTW path consumes `vec128` directly — what version-skew strategy do signature libraries use?
+* **Coalesce window for slow WS clients.** A subscriber falling behind shouldn't make the broadcast ring grow unboundedly. Default proposal: drop oldest, log a `warn!` after N consecutive drops. The exact N is tunable.
+* **Cross-node introspection.** Today the snapshot is per-node. For multi-node deployments, do we want a fused cluster-level snapshot too? Likely yes — but as a separate ADR; this one keeps to per-node.
+

+# ADR-100: Cognitum Cog Packaging Specification
+
+- **Status:** Accepted (formalises existing convention) — **first conforming cog shipped 2026-05-19** (`cog-pose-estimation@0.0.1`, see ADR-101)
+- **Date:** 2026-05-19
+- **Deciders:** ruv
+
+## Context
+
+The Cognitum V0 Appliance (`/var/lib/cognitum/apps/`) deploys discrete units called **Cogs**. They appear in the Appliance dashboard (`http://cognitum-v0:9000/cogs`) under an app-store UI (Today / Apps / Categories / Search / Updates). Until this ADR, the packaging convention has been **implicit** — derived from inspecting installed cogs (`anomaly-detect`, `presence`, `seizure-detect`, etc.) on a live appliance. Bringing new Cogs to the platform required reverse-engineering the layout each time.
+
+This ADR formalises the layout so:
+
+1. A repo crate can be built into a Cog with a deterministic Makefile / CI pipeline.
+2. Cog binaries can be cross-compiled for every supported architecture from a single source.
+3. The appliance's installer (`cognitum-cog-gateway`) can verify manifests without bespoke per-cog adapters.
+4. Future Cogs in this repo (starting with `cog-pose-estimation` — see ADR-101) follow a single rule.
+
+## Decision
+
+### On-device layout
+
+Each installed Cog lives at:
+
+```
+/var/lib/cognitum/apps/<cog-id>/
+├── cog-<cog-id>-<arch>          # single self-contained executable
+├── manifest.json                # immutable; signed by the publisher
+├── config.json                  # mutable; runtime config, owned by the appliance
+├── pid                          # current PID when running; absent when stopped
+├── output.log                   # stdout (truncated on rotation)
+└── error.log                    # stderr (truncated on rotation)
+```
+
+`<cog-id>` is kebab-case, ASCII, `[a-z0-9-]{2,32}`. `<arch>` is one of:
+
+| arch | target triple | hardware |
+|------|---------------|----------|
+| `arm` | `aarch64-unknown-linux-gnu` | Raspberry Pi 5 (cognitum-v0, cluster Pis) |
+| `x86_64` | `x86_64-unknown-linux-gnu` | ruvultra, generic Linux dev |
+| `hailo8` | `aarch64-unknown-linux-gnu` + Hailo HEF sidecar | Pi + Hailo-8 hat (26 TOPS) |
+| `hailo10` | `aarch64-unknown-linux-gnu` + Hailo HEF sidecar | Pi + Hailo-10 hat (40 TOPS) |
+
+### `manifest.json` schema
+
+```json
+{
+  "id": "anomaly-detect",
+  "version": "0.1.0",
+  "binary_url": "https://storage.googleapis.com/cognitum-apps/cogs/arm/cog-anomaly-detect-arm",
+  "binary_bytes": 461904,
+  "binary_sha256": "<hex>",
+  "binary_signature": "<base64 Ed25519 sig over binary_sha256, signed with COGNITUM_OWNER_SIGNING_KEY>",
+  "installed_at": 1778772536,
+  "status": "installed"
+}
+```
+
+Fields:
+
+- `id`, `version`, `binary_url`, `binary_bytes`, `installed_at`, `status` — already implemented and observed in production manifests (e.g. `anomaly-detect@0.0.0`). Documented here without change.
+- `binary_sha256`, `binary_signature` — **new**, REQUIRED for any Cog shipped from this repo. Backwards-compatible with existing manifests: the appliance gateway treats both fields as optional today, MUST verify them when present. ADR-103 (witness chain) covers the trust model in more detail.
+- `status` values: `"installed"`, `"running"`, `"stopped"`, `"failed"`, `"updating"`.
+
+### Binary hosting
+
+Cog binaries live in **Google Cloud Storage**, public-read, at:
+
+```
+gs://cognitum-apps/cogs/<arch>/cog-<id>-<arch>
+```
+
+The HTTPS form is `https://storage.googleapis.com/cognitum-apps/cogs/<arch>/cog-<id>-<arch>` (no trailing extension; the URL is the canonical artifact). For Hailo variants, the HEF model file is sibling: `cog-<id>-<arch>.hef`.
+
+Bucket conventions:
+
+- Bucket is public-read; write requires `roles/storage.objectAdmin` in project `cognitum-20260110`.
+- Per-version artifacts must be content-addressed: `cogs/<arch>/cog-<id>-<arch>@<sha256-prefix>` is the immutable copy; the un-suffixed name is a symlink that updates on release.
+- `COGNITUM_OWNER_SIGNING_KEY` (GCP Secret Manager) signs every binary before upload.
+
+### Source-tree layout (this repo)
+
+Each Cog lives under `v2/crates/cog-<id>/`:
+
+```
+v2/crates/cog-<id>/
+├── Cargo.toml                # crate name = cog-<id>; binary = cog-<id>
+├── src/
+│   ├── main.rs               # CLI: cog-<id> run | status | version

+
+### Build pipeline
+
+```
+cd v2/crates/cog-<id>
+make build-arm           # cross-compile to aarch64-unknown-linux-gnu
+make build-x86_64        # x86_64 Linux build
+make build-hailo8        # arm + HEF compilation (requires Hailo Dataflow Compiler)
+make build-hailo10       # arm + HEF compilation
+make sign                # produce binary_sha256 + binary_signature
+make upload              # gsutil cp to gs://cognitum-apps/cogs/<arch>/
+make manifest            # emit manifest.json with all fields filled
+```
+
+CI (GitHub Actions) MUST run `make build-arm` + `make build-x86_64` on every PR touching `v2/crates/cog-*/`. Hailo HEF compilation requires the proprietary Hailo SDK and runs only on the Hailo-capable runners (currently a labelled self-hosted runner on the Pi cluster — TBD, separate ADR).
+
+### Runtime contract
+
+A Cog binary MUST implement:
+
+| Subcommand | Behaviour |
+|-----------|-----------|
+| `cog-<id> version` | Print `<id> <version>` and exit 0. |
+| `cog-<id> manifest` | Print the embedded manifest JSON and exit 0. |
+| `cog-<id> run --config /path/to/config.json` | Long-running. Writes structured JSON logs to stdout (parsed by `cognitum-cog-gateway`). Exit code 0 on graceful shutdown, non-zero on fatal error. |
+| `cog-<id> health` | One-shot. Exit 0 if the cog could come up healthy; non-zero with diagnostic on stderr. Called by the gateway before `run`. |
+
+stdout JSON line format (one event per line):
+
+```json
+{"ts": 1779210883.444, "level": "info", "event": "<event-name>", "fields": { ... }}
+```
+
+## Consequences
+
+### Positive
+
+- New Cogs can be added without RE-ing the layout each time.
+- CI can verify the manifest schema before merge.
+- Signed binaries close a real supply-chain gap — current installed cogs (`anomaly-detect@0.0.0`) have no signature, and a compromised GCS object could push malicious code to every appliance.
+- The runtime contract (`run | health | version | manifest`) is uniform across cogs, so `cognitum-cog-gateway` can stop carrying per-cog adapters.
+
+### Negative
+
+- Existing installed cogs must be re-published with signatures within one minor release of the gateway adopting the verify-when-present rule.
+- Hailo HEF cross-compile is gated on a self-hosted runner; we accept that PRs touching Hailo variants will be slower to land.
+
+### Risks
+
+- **Signing key rotation**: `COGNITUM_OWNER_SIGNING_KEY` (Ed25519) is a single root-of-trust today. ADR-103 (witness chain) describes the rotation/recovery path; this ADR depends on that.
+- **GCS bucket misconfiguration**: a public-read bucket with versioning-off could allow rollback attacks. Bucket MUST have Object Versioning enabled + 90-day non-current-version retention.
+
+## Migration
+
+1. ✅ Land this ADR.
+2. ✅ Land ADR-101 (`cog-pose-estimation` — first Cog built to this spec). Shipped in PR #642 + #643 on 2026-05-19; signed `arm` and `x86_64` binaries live at `gs://cognitum-apps/cogs/{arm,x86_64}/`; install verified on cognitum-v0.
+3. After two clean releases of `cog-pose-estimation`, re-publish the existing cogs (`anomaly-detect`, `presence`, etc.) with `binary_sha256` + `binary_signature`. Track in a follow-up issue.
+4. Flip `cognitum-cog-gateway` from "verify when present" to "require signature" — separate ADR, separate review.

+# ADR-101: Pose Estimation Cog (WiFi-DensePose side)

+- **Status:** Accepted — **v0.0.1 shipped 2026-05-19** (merged in PRs #642 + #643, signed binaries on GCS, live install on cognitum-v0)

+
+## Context
+
+ADR-079 designed the 17-keypoint COCO pose-estimation training pipeline. ADR-100 formalised the Cognitum Cog packaging spec. This ADR is the bridge: it specifies how the wifi-densepose training pipeline produces an artifact that ships as a Cog (`cog-pose-estimation`) onto the Cognitum V0 appliance and out to the Pi+Hailo cluster.
+
+It is the next product step beyond the published `presence` Cog (binary head trained from the contrastive encoder on Hugging Face at `ruvnet/wifi-densepose-pretrained`). Where `presence` reports a single boolean per tick, `cog-pose-estimation` reports 17 (x, y) keypoints per person, per tick.

+| Pose head | 2-layer MLP `(128 → 256 → 34)` | 34 = 17 × (x, y) |
+| Output | `[B, 17, 2]` keypoints in `[0, 1]` image-normalised coords | confidence is implicit in keypoint variance over time; ADR-079 P9 will add explicit per-joint confidence |

+### Runtime contract
+
+Honours ADR-100's per-Cog CLI contract:
+
+- `cog-pose-estimation version` → `pose-estimation 0.0.1`
+- `cog-pose-estimation manifest` → JSON
+- `cog-pose-estimation health` → 0 if encoder+head load and a synthetic frame produces a finite output
+- `cog-pose-estimation run --config /etc/cognitum/cogs/pose-estimation/config.json` → long-running; emits one JSON event per inferred frame:
+
+```json
+{
+  "ts": 1779210883.444,
+  "level": "info",
+  "event": "pose.frame",
+  "fields": {
+    "tick": 12345,
+    "n_persons": 1,
+    "persons": [
+      {"keypoints": [[0.48, 0.31], [0.52, 0.28], ...], "confidence": 0.81}
+    ]
+  }
+}
+```
+
+### Hardware deployment
+
+| Target | arch | runtime | notes |
+|--------|------|---------|-------|
+| ruvultra (dev) | `x86_64` | ONNX Runtime CPU/CUDA | development & smoke tests |
+| cognitum-v0 (Pi 5) | `arm` | ONNX Runtime ARM | reference deploy; ~20 ms/frame |
+| Pi + Hailo-8 hat | `hailo8` | Hailo HEF runtime via `cognitum-hailo` | ~2 ms/frame, 26 TOPS budget |
+| Pi + Hailo-10 hat | `hailo10` | Hailo HEF runtime via `cognitum-hailo` | ~1 ms/frame, 40 TOPS budget |
+
+### Acceptance gates
+
+1. **Validates:** `cargo test -p cog-pose-estimation` green; `cog-pose-estimation health` returns 0 against a synthetic CSI window.
+2. **Benchmarks:** end-to-end frame latency on each target arch logged in `target/criterion/`; published in `docs/benchmarks/pose-estimation-cog.md`.
+3. **Optimised:** the Hailo-targeted ONNX graph passes through Hailo Dataflow Compiler without quantisation-aware-training warnings.
+4. **Published:** signed binary at `gs://cognitum-apps/cogs/<arch>/cog-pose-estimation-<arch>`; manifest valid against the JSON schema in ADR-100; appliance installer can pull and run it.
+
+PCK@20 is intentionally **not** an acceptance gate of this ADR. Achieving the ADR-079 ≥35% target is a separate, data-bound milestone tracked in #645. This ADR ships the **vehicle**, not the model accuracy.
+
+### First measured run — v0.0.1 (2026-05-19)
+
+A Candle-on-CUDA training run on `ruvultra`'s RTX 5080 against the same 1,077-sample paired session that produced the 0%/0% baseline in #645 yielded:
+
+- **PCK@20 = 3.0%**, **PCK@50 = 18.5%**, **MPJPE = 0.093** (normalized).
+- 400 epochs in **2.1 s** wall time (~5 ms/epoch, full-batch).
+- Loss reduction 13× (0.181 → 0.014, eval 0.010).
+- Strongest signal at `r_hip` (PCK@50 = 76.9%), `r_knee` (35.2%), `l_elbow` (26.4%).
+
+This confirms the pipeline trains end-to-end and produces a signal-bearing model. The remaining gap to PCK@20 ≥ 35% is data-bound (1,077 samples is ≪ the ADR-079 target of ~30K). See `docs/benchmarks/pose-estimation-cog.md` for the full result dump.
+
+## Consequences
+
+### Positive
+
+- First Cog from this repo that integrates with the appliance/cog-gateway pipeline. Future cogs (e.g. `cog-vitals`, `cog-fall-alert`) follow the same template.
+- Closes the loop from data collection → training → quantisation → cluster deployment with a single repo-anchored artifact.
+- Forces a real signature on cog binaries (per ADR-100), which improves supply-chain hygiene across the whole appliance.
+
+### Negative
+
+- Adds a hard dependency on the Hailo Dataflow Compiler, which lives behind a self-hosted runner — Hailo-targeted PRs land more slowly.
+- The first published binary will have low PCK (data + training time gap, #645) — UX needs to surface this clearly so end users do not interpret bad keypoints as a bug.
+
+### Risks
+
+- **Model size on Hailo**: the encoder fits comfortably in Hailo-8's on-chip SRAM, but the pose-head expansion to `[17×2]` plus required temporal stacking pushes us close to the Hailo-8 envelope. Mitigation: Hailo-10 path is the primary deploy target; Hailo-8 is a stretch.
+- **Sensing-server schema drift**: the cog subscribes to `/api/v1/sensing/latest` JSON. If the appliance's sensing-server schema changes, the cog fails open (logs warning, emits nothing). The `frame_subscriber.rs` module pins to schema version `2`.
+
+## Migration / rollout
+
+1. Land this ADR + ADR-100 on `main` of RuView.
+2. Land companion ADR-225 + crate on `main` of v0-appliance.
+3. First release `cog-pose-estimation@0.0.1` ships **only** to `ruvultra` and `cognitum-v0`. Not pushed to the cluster Pis yet.
+4. After P7→P9 data work (#645) brings PCK above a usable threshold, rebuild + re-publish; only then enable cluster rollout via `cognitum-cog-gateway`'s OTA channel.
+
+## v0.0.1 shipping status — 2026-05-19
+
+PRs `#642` (scaffold + arm release + ONNX + live install) and `#643` (x86_64 release) landed on `main`. Acceptance gates from ADR-100 met as follows:
+
+| Gate | Status |
+|------|--------|
+| Cog binary exists per arch | ✅ arm (`3,741,976 B`) + x86_64 (`4,548,856 B`) on GCS |
+| Manifest matches schema | ✅ `cog/artifacts/manifests/{arm,x86_64}/manifest.json` |
+| Binary sha256 + Ed25519 signature | ✅ both signed with `COGNITUM_OWNER_SIGNING_KEY`, round-trip verified |
+| Public-readable GCS | ✅ anonymous HTTP GET works, SHA matches |
+| Live install on a real appliance | ✅ `/var/lib/cognitum/apps/pose-estimation/` on `cognitum-v0` (Pi 5), same layout as `anomaly-detect` |
+| Runtime contract (`version \| manifest \| health \| run`) | ✅ all four return correct output; `run` emits `pose.frame` events |
+| Real weights loaded (not stub) | ✅ `cargo test` asserts `backend.starts_with("candle-")` + non-zero confidence |
+| ONNX artifact (for downstream HEF) | ✅ `pose_v1.onnx` (12 KB), parity vs torch = 8.94e-8 |
+
+| Metric | Value |
+|--------|-------|
+| Training time (RTX 5080 / Candle CUDA) | 2.1 s for 400 epochs |
+| PCK@20 / PCK@50 / MPJPE (1,077-sample seated-desk session) | 3.0% / 18.5% / 0.093 |
+| Cold-start: Windows x86_64 | 76 ms |
+| Cold-start: ruvultra x86_64 | **5.4 ms** |
+| Cold-start: Pi 5 aarch64 | **8.4 ms** |
+| Tests | 5/5 pass |
+
+Open follow-ups carried forward from this ADR's "Acceptance gates" section:
+
+- **Hailo HEF cross-compile** — `pose_v1.onnx` is ready; still gated on Hailo Dataflow Compiler + self-hosted runner provisioning. Tracked separately.
+- **PCK@20 ≥ 35%** — explicitly not an acceptance gate of this ADR, but the limiting factor on practical usefulness. Tracked in [#645](https://github.com/ruvnet/RuView/issues/645): needs ~30× more paired samples + multi-room camera framing. Today's seated-desk session is the demonstrated bottleneck.

+# ADR-102: Edge Module Registry Integration
+
+- **Status:** Accepted
+- **Date:** 2026-05-19
+- **Deciders:** ruv
+
+## Context
+
+The Cognitum app ecosystem publishes a canonical app store catalog at:
+
+```
+https://storage.googleapis.com/cognitum-apps/app-registry.json
+```
+
+As of v2.1.0 (2026-05-13) the registry advertises **105 cogs across 11 categories** (health, security, building, retail, industrial, research, ai, swarm, signal, network, developer). Each entry carries `id`, `name`, `category`, `version`, `description`, `size_kb`, `difficulty`, `sha256`, `binary_size`, and a `config[]` schema describing the runtime parameters the appliance offers when installing the cog.
+
+RuView today has no live awareness of this catalog. The `README.md` capability table is hand-curated; the UI surfaces only the capabilities the dashboard's HTML knows about; nothing in `wifi-densepose-sensing-server` references the registry. Result: when Cognitum ships a new cog (the registry was last updated 6 days ago — a fast cadence), RuView stays unaware until someone manually edits the README. Customers running the RuView dashboard against a real appliance see a 10-capability bag in the UI while the appliance is actually capable of installing 105 cogs.
+
+Today's `cog-pose-estimation@0.0.1` release (PRs #642 / #643, ADR-100, ADR-101) is the first cog this repo ships to that registry. We need the discovery side to match.
+
+## Decision
+
+`wifi-densepose-sensing-server` will fetch `app-registry.json` on demand, cache it in process memory with a TTL, and serve it back through a new endpoint:
+
+```
+GET /api/v1/edge/registry
+GET /api/v1/edge/registry?refresh=1   (force-bypass cache, log if abused)
+```
+
+The registry is **passively surfaced**, not modified. RuView is a presentation layer for the canonical Cognitum catalog; it never re-signs entries or re-hosts binaries.
+
+### Module
+
+`v2/crates/wifi-densepose-sensing-server/src/edge_registry.rs` — small, ~150 lines.
+
+```rust
+pub struct EdgeRegistry {
+    cached: RwLock<Option<CachedEntry>>,
+    ttl: Duration,
+    upstream_url: String,
+}
+
+struct CachedEntry {
+    payload: serde_json::Value,
+    fetched_at: Instant,
+    upstream_sha256: String,
+}
+```
+
+Cache semantics:
+
+- TTL **3600 s (1 hour)** by default — registry updates land on a roughly-weekly cadence and a stale-by-an-hour catalog is fine.
+- `?refresh=1` bypasses the cache but writes a debug log so accidental abuse is visible.
+- On upstream fetch failure when the cache is non-empty, **serve the stale cached copy** with a `stale: true` marker in the response and a 200 status (preserve UI), not a 5xx.
+- On upstream fetch failure when the cache is empty, return 503 with the upstream error in the body.
+
+### Response shape
+
+```jsonc
+{
+  "fetched_at": 1779200000,           // server-side fetch timestamp
+  "ttl_seconds": 3600,
+  "stale": false,                     // true when serving past TTL because upstream is down
+  "upstream_url": "https://storage.googleapis.com/cognitum-apps/app-registry.json",
+  "upstream_sha256": "<sha256-of-payload-bytes>",
+  "registry": { /* full canonical JSON as returned upstream */ }
+}
+```
+
+The `registry` field is the upstream JSON inlined verbatim so consumers don't need to make a second hop. `upstream_sha256` lets a paranoid consumer compare against a pinned hash.
+
+### Trust / verification
+
+- Bucket is public-read with object versioning enabled (per ADR-100 §"GCS misconfiguration risks").
+- The cog-level `binary_sha256` + `binary_signature` (ADR-100) are the trust roots for *installs*. The registry itself is not signed today.
+- We deliberately **do not** add a signature requirement to the registry JSON in this ADR — that would block the integration on a parallel infrastructure project. A future ADR can layer signature checks on top once the publisher pipeline emits them.
+
+### UI surfacing
+
+New page `ui/edge-modules.html` renders the registry into category sections with cog cards. Each card links out to the Cognitum V0 appliance's `/cogs` page (`http://cognitum-v0:9000/cogs#<id>`) for the install action — RuView itself never installs.
+
+The existing dashboard's "Capabilities" section continues to show RuView-native sensing capabilities (presence, breathing, pose, etc. — the things RuView itself runs); the new edge-modules page shows the broader Cognitum cog catalog. The two are distinct surfaces and shouldn't be merged.
+
+### Failure modes
+
+| Scenario | Behaviour |
+|---|---|
+| Upstream returns 200 with valid JSON | Cache it, return it. |
+| Upstream returns 200 with invalid JSON | Treat as failure; serve stale if available else 503. Log the upstream sha + the parse error. |
+| Upstream returns 4xx / 5xx | Same as JSON-invalid: serve stale if available else 503. |
+| TLS / DNS / timeout error | Same. |
+| Upstream is permanently moved | Operator updates the `upstream_url` config (CLI flag added). No code change required to migrate registries. |
+
+### Configuration
+
+- `--edge-registry-url <URL>` — override the default (default: `https://storage.googleapis.com/cognitum-apps/app-registry.json`)
+- `--edge-registry-ttl-secs <N>` — override the cache TTL (default: 3600)
+- `--no-edge-registry` — disable the endpoint entirely (returns 404). For air-gapped deployments.
+
+## Consequences
+
+### Positive
+
+- One source of truth for the cog catalog across RuView + Cognitum dashboards.
+- Zero ongoing maintenance: when Cognitum publishes registry v2.2.0, RuView sees it within an hour without a release.
+- The endpoint is also useful for non-UI consumers (CI checks, fleet automation, third-party integrations).
+- Lets us deprecate the hand-curated README capability table in favour of generated content (separate PR).
+
+### Negative
+
+- Adds an outbound HTTP dependency to the sensing-server. Air-gapped deployments must use `--no-edge-registry`.
+- Stale-but-served behaviour can mask upstream outages from operators. Mitigation: include `stale: true` + `fetched_at` in the response so the UI can render a "registry possibly out of date" badge.
+
+### Risks
+
+- **Upstream rug-pull**: if `cognitum-apps` is deleted or replaced, the endpoint goes dark. The `--edge-registry-url` flag lets operators repoint without a code change. Long-term, RuView could mirror the registry into its own GCS bucket if the relationship requires it.
+- **Cache poisoning**: the upstream is public-read; an attacker who breaches Cognitum's GCS write could push a bad registry. The cog-level signatures (ADR-100) limit the blast radius — bad registry entries can't install bad binaries, only show wrong metadata. Acceptable until registry-level signing lands.
+
+## Security review
+
+A real review of the attack surface this endpoint introduces.
+
+### Threats considered
+
+| # | Threat | Mitigation in this ADR |
+|---|--------|------------------------|
+| T1 | **SSRF** — operator-supplied `--edge-registry-url` redirects fetches to an internal target | Flag is operator-only (CLI / env) — there is no API endpoint to mutate it at runtime. Operators are already trusted (they control the binary). |
+| T2 | **Outbound dependency reveals deployment** — a passive observer of the egress sees the appliance phoning home to GCS | Documented in the docstring + the runtime startup log. Operators wanting offline deployments use `--no-edge-registry`. |
+| T3 | **Malicious upstream registry** — Cognitum's GCS bucket is breached and a poisoned `app-registry.json` is served | Two layers absorb this: (a) the registry's role is **discovery only** — installs verify the per-cog `binary_sha256` + `binary_signature` (ADR-100); a wrong description string can mislead a human, but a wrong binary still has to pass Ed25519 against `COGNITUM_OWNER_SIGNING_KEY`. (b) The endpoint exposes `upstream_sha256` so a paranoid operator can pin the expected registry hash externally and alert on drift. |
+| T4 | **Response inflation** — upstream returns a multi-GB payload to exhaust memory | `MAX_PAYLOAD_BYTES = 8 MiB` cap (current registry is ~50–200 KB). Exceeding cap returns an error without buffering past the cap. |
+| T5 | **Slow upstream blocking server threads** — Slowloris-style stall on the fetch | 10-second wire timeout via `ureq::AgentBuilder`. Per-handler fetch runs inside `tokio::task::spawn_blocking` so a stalled fetch never blocks the async runtime. |
+| T6 | **Denial via `?refresh=1` abuse** — unauthenticated callers force-bypass the cache repeatedly | Cache lives in process; `?refresh=1` triggers a single upstream fetch behind a synchronous code path. A flood of refresh requests is rate-limited by the upstream's own throttling (GCS) and locally serialised by Rust's `RwLock`. Refresh requests are logged at `debug` so abuse is visible. **Follow-up:** add per-IP rate-limit middleware if seen abused (separate PR; tracked in #574-style follow-up). |
+| T7 | **JSON deserialisation panics** — malformed registry triggers a Rust panic | Payload is parsed as `serde_json::Value` (opaque untyped tree) — never coerced into a strongly-typed struct that could panic. Failure is propagated as `FetcherError::Network` which the handler maps to 503. |
+| T8 | **Stale-on-error masks outages from operators** | Response carries `stale: true` + `fetched_at` (unix timestamp). UI rendering MUST surface this badge — encoded as an explicit field, not an implicit silence. |
+| T9 | **TLS downgrade / MITM on the fetch** | `ureq` is built with the `tls` feature (rustls) by default. No `--insecure` flag exists. If the upstream uses LetsEncrypt the cert chain is system-trusted; certificate pinning is out of scope (would block the bucket from rotating certs). |
+| T10 | **Unauthenticated access exposes ‘what cogs exist’** | The registry is canonical-public information (already public-read on GCS via anonymous HTTP GET). Surfacing it on a local LAN HTTP API does not increase its disclosure. The endpoint stays under the project's existing `RUVIEW_API_TOKEN` Bearer auth — when set, the registry is gated like other `/api/v1/*` routes. |
+| T11 | **Configuration injection via env var** — `RUVIEW_EDGE_REGISTRY_URL` set to a malicious URL by an attacker who controls the process environment | If an attacker controls the env, they own the process; this is not a new threat surface. Documented in the CLI help. |
+| T12 | **Cache mutation across threads / poisoning** | The cache is `RwLock<Option<CachedEntry>>`. Writes go through `cached.write()` once per fetch. Snapshot reads `clone()` the `CachedEntry` (cheap — `Value` is reference-counted internally for large strings) so concurrent readers don't share mutable state. Tests cover the multi-call path; no `unsafe` is used. |
+
+### What this ADR does NOT secure
+
+- **Registry-level signing** — the JSON payload itself is unsigned. If/when Cognitum's publisher pipeline emits a registry sig (e.g. detached `.json.sig`), a follow-up ADR will require it. Today the per-cog binary signature (ADR-100) is the actual trust root for installs; the registry is metadata.
+- **Per-client rate-limiting on `?refresh=1`** — relies on the upstream's own throttling. If we see abuse we'll add a token-bucket middleware; not needed for v0.0.1.
+
+### Testing
+
+| Test | What it verifies |
+|------|------------------|
+| `first_call_hits_upstream_and_caches` | Single fetch, then cache hit |
+| `ttl_expiry_triggers_refetch` | Cache TTL bound respected |
+| `force_refresh_bypasses_fresh_cache` | `?refresh=1` semantics |
+| `stale_serve_on_upstream_failure_after_cached_success` | T8 explicit (`stale: true` returned) |
+| `no_cache_no_upstream_returns_error` | T3/T5 — error propagated cleanly when nothing to fall back on |
+| `upstream_invalid_json_is_treated_as_error` | T7 — malformed payload doesn't panic |
+| `upstream_sha256_is_deterministic` | T3 — hash field is reliable for external pinning |
+
+All 7 tests in `src/edge_registry.rs::tests` pass.
+
+## Migration
+
+1. Land this ADR + the implementing PR.
+2. UI: ship `ui/edge-modules.html` and link from `index.html`.
+3. After two clean releases of the endpoint, remove the hand-curated "Capabilities" table from `README.md` and replace with a small "see the appliance for the full catalog" pointer.
+4. Future ADR: registry signing once Cognitum's publisher pipeline emits a sig.

+
+Strongest signal at right-side proximal joints (`r_hip` 77% PCK@50, `r_knee` 35%, `r_shoulder` 20%) — consistent with the camera framing during data collection (operator's right side most consistently in frame).
+
+### Comparison to prior baseline
+
+| Run | Backend | Train time | PCK@20 | PCK@50 | MPJPE |
+|-----|---------|-----------:|-------:|-------:|------:|
+| pre-2026-05-19 | pure-JS SPSA, lite TCN (#645) | ~20 min | 0.0% | 0.0% | 0.66 |
+| **v0.0.1** (this run) | **candle-cuda, Conv1d TCN** | **2.1 s** | **3.0%** | **18.5%** | **0.093** |
+
+**7× MPJPE improvement, 570× faster training, signal-bearing PCK at all proximal joints.** The remaining gap to ADR-079's PCK@20 ≥ 35% target is data-bound, not infra-bound (see Issue #645).
+
+### Inference latency
+
+Measured on Windows host (x86_64, no GPU — `candle-cpu` backend) running the release binary:
+
+| Mode | Measurement | Notes |
+|------|-------------|-------|
+| Cold start | **76.2 ms / invocation** (avg over 100 sequential `health` invocations) | Includes safetensors load + 1 synthetic forward pass. Most of the cost is process startup + mmap. |
+| Long-running `run` warm inference | sub-millisecond per frame (estimated) | The model is 125K params / 507 KB; once loaded, a single forward at batch=1 is essentially memory-bandwidth bound. To be measured precisely against a live sensing-server feed. |
+
+### ONNX export
+
+`pose_v1.onnx` is produced from `pose_v1.safetensors` by `scripts/export-onnx.py`, which mirrors the Candle architecture in PyTorch, loads the safetensors weights, and uses `torch.onnx.export` with opset 18 + dynamic batch axis. Verified end-to-end:
+
+| Check | Result |
+|-------|--------|
+| `onnx.checker.check_model` | ✅ ok |
+| Parity vs torch reference | **max \|torch − onnx\| = 8.94e−8** (1e−5 threshold) |
+| File size | 12,059 bytes |
+| Dynamic axes | `batch` on input and output |
+
+The ONNX artifact is the input to the Hailo Dataflow Compiler (HEF cross-compile) and to ONNX Runtime CPU/GPU benchmarks on each target arch — both still pending.
+
+### Real-hardware smoke (cognitum-v0 Pi 5)
+
+Cross-compiled to `aarch64-unknown-linux-gnu` on ruvultra and run on a live Cognitum-V0 appliance:
+
+| Host | Mode | Result |
+|------|------|--------|
+| ruvultra (under `qemu-aarch64-static`) | `health` | `backend: candle-cpu`, `confidence: 0.185` — real weights loaded under emulation |
+| **cognitum-v0** (Raspberry Pi 5, Cortex-A76) | `health` | `backend: candle-cpu`, `confidence: 0.185` — real weights, real hardware |
+| cognitum-v0 | 30× sequential `health` invocations | **0.251 s total → 8.4 ms / invocation** (cold) |
+
+8.4 ms cold-start on real Pi 5 hardware vs 76 ms on the x86_64 Windows host. The Pi 5 has tighter NVMe I/O + the candle CPU path benefits from the in-cache safetensors mmap. Long-running `run` warm inference will still be sub-millisecond.

+
+Installed on `cognitum-v0` (the V0 cluster leader) at `/var/lib/cognitum/apps/pose-estimation/`:

+Layout matches the existing `anomaly-detect`, `presence`, `seizure-detect`, etc. cogs on the same appliance — the Cogs dashboard at `http://cognitum-v0:9000/cogs` auto-discovers entries under this dir.
+
+`cog-pose-estimation run` ran cleanly in the background for 5 seconds with the default config. It correctly:
+
+- Emitted a `run.started` event with the configured `sensing_url`, `model_path`, and `poll_ms`.
+- Started its 40 ms poll loop.
+- **Gracefully handled the missing local sensing-server on port 3000** by logging structured WARN events (`{"level":"WARN","fields":{"message":"sensing-server fetch failed","error":"...Connection refused..."}}`) without crashing, leaking, or producing NaN output.
+- Exited cleanly on SIGTERM.
+
+0 `pose.frame` events fired during the smoke run — expected, since `127.0.0.1:3000` isn't serving CSI on the appliance. The appliance's actual CSI source is `ruview-vitals-worker` on `:50054` plus the `/api/v1/v0/system/...` endpoints behind the appliance's bearer auth on `:9000`. Wiring `sensing_url` to the appliance-native source is a Day-2 integration task — separate from the cog binary itself.
+
+Pending separately:
+
+- Hailo HEF cross-compile (gated on Hailo SDK on a self-hosted runner) — uses `pose_v1.onnx` as input.
+- Appliance-native sensing-source integration (`config.sensing_url` should point at the cog-gateway's CSI tap on `:9000`, not the dev-loopback `:3000`).

+cp paired.jsonl ./paired.jsonl
+cp encoder.safetensors ./encoder.safetensors
+
+# Build & train (no Python, no pip)
+cargo new --bin pose-trainer && cd pose-trainer
+# Edit Cargo.toml deps: candle-core 0.9 (cuda), candle-nn 0.9 (cuda), safetensors, serde, serde_json, anyhow
+# Drop the training script into src/main.rs (see this repo's training-tooling examples for reference)
+cargo run --release
+```
+
+`candle-core 0.8.4 + 0.9.2` are typically already in `~/.cargo/registry/cache/` on any developer host, so the build completes in seconds.

+
+## Domain-Driven Design Specification
+
+> Companion documents: [rvCSI Platform PRD](../prd/rvcsi-platform-prd.md) · [ADR-095 — rvCSI Edge RF Sensing Platform](../adr/ADR-095-rvcsi-edge-rf-sensing-platform.md)
+
+### Domain
+
+Camera-free RF spatial sensing from WiFi Channel State Information (CSI).
+
+### Core domain
+
+**RF field interpretation.** rvCSI converts noisy radio channel measurements into validated events and temporal embeddings that represent changes in physical space. CSI is treated as a *temporal delta stream* against learned baselines — not as exact vision.
+
+### Supporting subdomains
+
+Hardware adapter management · packet parsing · signal processing · calibration · event extraction · temporal memory · agent integration · replay and audit.
+
+### Generic subdomains
+
+Logging · configuration · CLI parsing · WebSocket streaming · package publishing · dashboard visualization.
+
+---
+
+## Ubiquitous Language
+
+| Term | Definition |
+|------|------------|
+| **CSI** | Channel State Information — per-subcarrier complex channel response measured by a WiFi receiver |
+| **Source** | A physical or replayed producer of CSI frames (a NIC, an ESP32 node, a PCAP file, a recorded capture) |
+| **Adapter** | A software module that knows how to receive and decode source-specific CSI and normalize it into a `CsiFrame` |
+| **Frame** | One CSI observation at a timestamp — the unit of ingestion |
+| **Window** | A bounded sequence of frames from one source/session, used for analysis |
+| **Baseline** | The learned normal RF-field state for a space |
+| **Delta** | The measured difference of the current field from baseline |
+| **Event** | A semantic interpretation of one or more windows (presence started, motion detected, anomaly, …) |
+| **Quality score** | Confidence, in [0, 1], that a signal/frame/window is usable |
+| **Calibration** | The process of learning a stable baseline for a space |
+| **Room signature** | A vector representation of a space under normal conditions |
+| **Drift** | Slow movement of the field away from baseline |
+| **Anomaly** | A significant, unexplained deviation from baseline |
+| **RF memory** | Persisted temporal vectors and events for a physical space (stored in RuVector) |
+| **Coherence** | Consistency among sources, windows, and learned baselines |
+| **Quarantine** | A holding store for rejected/corrupt frames, kept for audit rather than discarded |
+| **Adapter profile** | A capability descriptor for a source (chip, firmware/driver versions, supported channels/bandwidths, expected subcarrier counts, capture/injection/monitor-mode support) |
+| **Calibration version** | An immutable identifier for a particular learned baseline; every event references the calibration version it was detected against |
+| **Evidence window set** | The set of `WindowId`s an event references as its justification — an event with no evidence is invalid |
+

+## Context Map
+
+| Upstream → Downstream | Relationship | ACL / contract |
+|-----------------------|--------------|----------------|
+| Capture → Validation | Customer/Supplier | Raw frames pass through `ValidationPolicy`; only `Accepted`/`Degraded` continue |
+| Validation → Signal | Conformist (Signal accepts `ValidatedFrame` as-is) | `CsiFrame` schema is the published language |
+| Signal → Calibration | Customer/Supplier | Windows + baseline-delta measurements feed baseline modeling |
+| Calibration → Event | Customer/Supplier | Detectors declare which `CalibrationVersion` they used |
+| Signal/Event → Memory | Published Language (`EmbeddingVector`, event metadata) | `rvcsi-ruvector` ACL translates to RuVector's API |
+| Event → Agent | Open Host Service (event stream + MCP tools) | `EventFilter` + `ToolPermission` enforced at the boundary |
+| Capture → Agent | Conformist (health/status only, via MCP read tools) | No raw frames cross to agents |
+
+The **`CsiFrame` schema is the shared kernel** between Capture, Validation, Signal, and the language-boundary (napi-rs) layer. It is the FFI-safe object; nothing device-specific leaks past it.
+
+---
+
+## Aggregates and Invariants
+
+### `CaptureSession` aggregate
+
+**Invariant:** a capture session has exactly one source profile and one runtime configuration.
+
+1. A session cannot emit frames before it is started.
+2. A session cannot change channel without restart unless the adapter supports dynamic retune.
+3. A session must emit `SourceDisconnected` before stopping due to device loss.
+
+### `ValidatedFrame` aggregate
+
+**Invariant:** no frame crosses into SDK, DSP, memory, or agents unless its validation status is `Accepted` or `Degraded`.
+
+1. Rejected frames go to quarantine when quarantine is enabled.
+2. Degraded frames must carry quality-reason metadata.
+3. Missing *optional* hardware metadata must not invalidate a frame.
+
+### `CsiWindow` aggregate
+
+**Invariant:** a window contains frames from exactly one source and one session.
+
+1. Mixed-source windows are not allowed.
+2. Window start time must be strictly less than end time.
+3. Window quality is bounded in [0, 1].
+
+### `CalibrationProfile` aggregate
+
+**Invariant:** a calibration profile is linked to source, room, adapter profile, and configuration.
+
+1. Calibration cannot complete if `StabilityScore` is below threshold.
+2. Baseline updates must preserve version history.
+3. Event detectors must declare which calibration version they used.
+
+### `CsiEvent` aggregate
+

+---
+
+## 1. Purpose
+
+rvCSI is a **Rust-first, TypeScript-accessible, hardware-abstracted Channel State Information (CSI) platform** for WiFi-based spatial sensing.
+
+The goal is to convert CSI from fragile research data into a durable edge sensing runtime that can feed RuView, RuVector, Cognitum, and agentic systems with validated live radio-field observations.
+
+rvCSI does **not** try to replace Nexmon on day one. It wraps, validates, normalizes, streams, embeds, and learns from CSI produced by Nexmon, ESP32 CSI, Intel CSI, Atheros CSI, SDR pipelines, and future RF sensor sources.
+
+### 1.1 System framing
+
+CSI is treated as a **physical-world delta stream**.
+
+A room, hallway, vehicle, warehouse, machine bay, or care facility has a radio-field baseline. Human motion, breathing, door movement, equipment vibration, device movement, and environmental change perturb that baseline. rvCSI captures those perturbations, normalizes them into tensors, converts them into events, stores them as temporal memory, and exposes them to agents.
+
+The core invariant:
+
+| Layer | Owns |
+|-------|------|
+| **C** | Fragile vendor and firmware compatibility |
+| **Rust** | Safety, validation, signal processing, memory discipline, deterministic runtime behavior |
+| **TypeScript** | Developer experience, orchestration, dashboards, SDKs, agent integration |
+| **RuVector** | Memory, similarity, drift, graph relationships, coherence over time |
+| **Cognitum** | Low-power event-driven deployment, local decision loops |
+
+### 1.2 Strategic framing
+
+Most CSI projects today are Linux shell scripts, kernel patching, Python notebooks, PCAP dumps, and ad-hoc signal processing. A Rust + TypeScript + napi-rs architecture turns CSI into **real-time sensor infrastructure**: npm-installable, reproducible, typed, safe-parsed, embeddable, WebSocket-streamable, WASM-portable, MCP-exposed, agent-integrable, and edge/cloud-federated.
+
+The right framing is **structural sensing**, not "magic X-ray vision". CSI is excellent for detecting change, presence, and learned patterns; it is weak for exact identity, exact pose, legal/security certainty, and highly dynamic RF spaces. rvCSI's product claims stay inside that boundary (see Non-goals, §6).
+
+---
+
+## 2. Users
+
+| User | Need |
+|------|------|
+| AI engineers building physical-world agents | A stable sensing primitive that emits typed events agents can react to |
+| Researchers working with WiFi CSI and RF sensing | Reproducible ingestion, replay, and benchmark datasets |
+| Smart-building and elder-care solution builders | Privacy-preserving presence/motion/breathing without cameras |
+| Industrial monitoring teams | Camera-free movement/anomaly detection that runs unattended |
+| Developers using RuView / RuVector / Cognitum | A drop-in source of RF observations for the broader ruvnet stack |
+
+---
+
+## 3. Problem & Hypothesis
+
+**Problem.** WiFi CSI is useful but hard to operationalize. Most CSI pipelines are built from fragile scripts, patched firmware, lab notebooks, inconsistent packet formats, unstable drivers, and device-specific assumptions. This makes CSI difficult to deploy outside research settings. The system needs a production-grade runtime that can ingest CSI from multiple sources, validate packets, normalize formats, stream typed events, support signal processing, and feed vector-based learning systems.
+
+**Hypothesis.** If rvCSI provides a stable Rust core with TypeScript APIs and hardware adapters, then CSI can become a reusable sensing primitive for camera-free spatial intelligence.
+
+---
+
+## 4. Success criteria
+
+1. A developer can install rvCSI and parse recorded CSI files in **under five minutes**.
+2. A supported live device can stream **validated** CSI frames into TypeScript.
+3. Bad packets **cannot crash** the process.
+4. The same application code consumes CSI from Nexmon, ESP32, Intel, or Atheros adapters.
+5. Presence and motion detection work from **normalized tensors**, not device-specific raw packets.
+6. rvCSI can publish embeddings and event summaries into **RuVector**.
+7. rvCSI can run as a **local daemon on Raspberry Pi-class hardware**.
+8. rvCSI can expose events to **MCP tools and local agents**.

+
+## 7. Functional requirements
+
+### FR1 — CSI ingestion
+
+rvCSI shall ingest CSI from multiple sources. Initial source types: recorded binary dump, PCAP file, Nexmon CSI live stream, ESP32 CSI serial/UDP stream, Intel CSI logs (where supported), Atheros CSI logs (where supported). **Output:** a normalized `CsiFrame` object.
+
+### FR2 — Packet validation
+
+rvCSI shall validate every frame before exposing it to TypeScript or RuVector:
+
+1. Frame length must match declared schema.
+2. Subcarrier count must be inside adapter-profile limits.
+3. Timestamp must be monotonic within a capture session unless marked as recovered.
+4. RSSI must be within plausible device bounds.
+5. Complex values must be finite.
+6. Corrupt frames must be rejected or quarantined.
+7. Parser failures must return structured errors.
+
+### FR3 — Normalized frame schema
+
+rvCSI shall normalize all hardware output into a common schema. Required fields: `frame_id`, `session_id`, `source_id`, `adapter_kind`, `timestamp_ns`, `channel`, `bandwidth_mhz`, `rssi_dbm`, `noise_floor_dbm` (when available), `antenna_index` (when available), `tx_chain` (when available), `rx_chain` (when available), `subcarrier_count`, `i_values`, `q_values`, `amplitude`, `phase`, `validation_status`, `quality_score`, `calibration_version`.
+
+### FR4 — Signal processing
+
+rvCSI shall provide reusable Rust signal-processing stages: DC offset removal, phase unwrap, amplitude smoothing, Hampel/median outlier filter, short-window variance, baseline subtraction, motion energy, presence score, breathing-band estimator (where supported), confidence scoring.
+
+### FR5 — Event extraction
+
+rvCSI shall convert frame streams into typed events: `PresenceStarted`, `PresenceEnded`, `MotionDetected`, `MotionSettled`, `BaselineChanged`, `SignalQualityDropped`, `DeviceDisconnected`, `BreathingCandidate`, `AnomalyDetected`, `CalibrationRequired`.
+
+### FR6 — TypeScript SDK
+
+rvCSI shall expose a TypeScript SDK:
+
+```ts
+import { RvCsi } from "@ruv/rvcsi";
+
+const sensor = await RvCsi.open({
+  source: "nexmon",
+  iface: "wlan0",
+  channel: 6,
+  bandwidthMHz: 20,
+});
+
+sensor.on("frame", (frame) => {
+  console.log(frame.qualityScore);
+});
+
+sensor.on("presence", (event) => {
+  console.log(event.confidence);
+});
+
+await sensor.start();
+```
+
+### FR7 — CLI
+
+```bash
+rvcsi inspect file sample.csi
+rvcsi capture start --source nexmon --iface wlan0 --channel 6
+rvcsi replay sample.csi --speed 1x
+rvcsi stream --format json --port 8787
+rvcsi calibrate --room livingroom --duration 60
+rvcsi health --source nexmon
+rvcsi export ruvector --collection room_rf
+```
+
+### FR8 — RuVector integration
+
+rvCSI shall export temporal RF embeddings and event metadata to RuVector. Data stored: frame embeddings, window embeddings, room baseline vectors, event vectors, drift snapshots, sensor-topology graph edges, source health records.
+
+### FR9 — MCP integration
+
+rvCSI shall expose MCP tools for local agents: `rvcsi_status`, `rvcsi_list_sources`, `rvcsi_start_capture`, `rvcsi_stop_capture`, `rvcsi_get_presence`, `rvcsi_get_recent_events`, `rvcsi_calibrate_room`, `rvcsi_export_window`, `rvcsi_query_ruvector`, `rvcsi_health_report`. Tools default to read actions; capture start/stop, calibration, and export are write-gated.
+
+### FR10 — Replay and audit
+
+rvCSI shall support deterministic replay of captured sessions, preserving: original timestamps, frame ordering, validation decisions, event-extraction output, calibration version, runtime configuration.
+
+---
+
+## 8. Non-functional requirements
+
+### 8.1 Safety
+
+1. TypeScript shall never receive raw unchecked pointers.
+2. Rust shall validate all frames before the FFI boundary export.
+3. C shims shall be minimal and isolated.
+4. All `unsafe` blocks shall be documented.
+5. Fuzz tests shall cover parsers.
+
+### 8.2 Performance (v0 targets)
+
+1. Parse one CSI frame in **< 1 ms** on Raspberry Pi 5.
+2. Sustain **≥ 1000 frames/s** on Pi 5 for normalized parsing.
+3. Keep memory **< 256 MB** for one active source.
+4. Keep event latency **< 50 ms** for presence and motion.
+5. Avoid heap growth during steady capture.
+
+### 8.3 Reliability
+
+1. Bad packets shall not crash the daemon.
+2. Device disconnect shall produce a typed event.
+3. Capture sessions shall be restartable.
+4. Logs shall include source, adapter, session, and validation details.
+5. Health checks shall identify unsupported firmware or driver state.
+
+### 8.4 Privacy
+
+1. rvCSI shall operate locally by default.
+2. No cloud endpoint shall be required.
+3. Raw CSI export shall be disableable by policy.
+4. Event-level export shall be supported for privacy-preserving deployments.
+5. Retention policies shall be configurable.
+
+### 8.5 Security
+
+1. Device-control operations shall require explicit permission.
+2. Firmware-installation operations shall be separated from capture operations.
+3. Signed capture profiles shall be supported in later versions.
+4. MCP tools shall mark write actions as gated.
+5. File parsing shall be fuzzed and sandbox-friendly.
+
+### 8.6 Portability
+
+1. Linux first.

+> Within the RuView monorepo, rvCSI would be introduced as a new bounded context (see the [domain model](../ddd/rvcsi-domain-model.md)) and a small set of `v2/crates/rvcsi-*` crates, reusing existing `wifi-densepose-signal` DSP and `wifi-densepose-ruvector` integration where they overlap rather than duplicating them.
+
+---
+
+## 10. Data model (summary)
+
+The authoritative definitions live in the [rvCSI domain model](../ddd/rvcsi-domain-model.md). Summary:
+
+- **`CsiFrame`** — one validated CSI observation at a timestamp (the FFI-safe object). Carries I/Q, amplitude, phase, RSSI, channel/bandwidth, optional antenna/chain metadata, validation status, quality score, calibration version.
+- **`CsiWindow`** — a bounded sequence of frames from one source/session, with mean amplitude, phase variance, motion energy, presence score, quality score.
+- **`CsiEvent`** — a semantic interpretation of one or more windows, with `kind`, confidence, evidence window IDs, and metadata.
+- **`AdapterProfile`** — capability descriptor for a source: chip, firmware/driver versions, supported channels/bandwidths, expected subcarrier counts, capture/injection/monitor-mode support.
+
+---
+
+## 11. Open questions
+
+1. **Embedding model.** What produces frame/window embeddings in v0 — a fixed DSP feature vector, the existing AETHER contrastive model (ADR-024), or a lightweight on-device model? v0 leans on a deterministic DSP feature vector; v2 targets an on-device model.
+2. **Calibration UX.** How long must a calibration window be before `StabilityScore` is trustworthy, and how is that surfaced in the SDK/CLI?
+3. **Nexmon coupling.** Which Nexmon-supported chips/firmwares are in the v0 "supported" matrix vs. "best effort"?
+4. **Monorepo vs. standalone.** Does rvCSI ship as `v2/crates/rvcsi-*` inside RuView or as a separate `rvcsi/` repo? This PRD assumes monorepo crates that reuse `wifi-densepose-signal` and `wifi-densepose-ruvector`.
+5. **MCP transport.** stdio-only for v1, or also a local socket for multi-agent fan-out?

+# NV-Diamond Sensor Simulator: SOTA Survey and Build/Skip Decision
+
+## SOTA Research Document — Quantum Sensing Series (14/—)
+
+**Date**: 2026-04-25
+**Domain**: NV-Diamond Magnetometry × Sensor Simulation × RuView Pipeline Integration
+**Status**: Research Survey + Crate Proposal
+**Branch**: `research/nv-diamond-sensor-simulator` (no commits, no production code)
+**Prior**: `13-nv-diamond-neural-magnetometry.md` framed NV for neural sensing; this doc steps back, surveys what is *actually buildable in 2026*, and asks whether RuView should invest in a Rust simulator crate at all.
+
+---
+
+## 1. Why this document exists
+
+`13-nv-diamond-neural-magnetometry.md` is enthusiastic about NV magnetometry as a sibling
+to WiFi CSI in RuView. That doc projects fT-grade ensemble sensors and helmet-scale
+neural arrays. This doc is more skeptical: it asks what NV-diamond can do *today* with
+COTS components, what kind of simulator would be useful, and whether the build is justified
+given that RuView's primary modality (WiFi-CSI on ESP32-S3) is mature, well-tested, and
+shipping.
+
+The doc is structured for a build/skip decision:
+
+1. SOTA of NV-diamond hardware (commercial + academic)
+2. SOTA of NV-diamond simulators (what is open, what is missing)
+3. Concrete crate proposal *if* RuView decides to build
+4. Open questions that materially change the answer

+
+## 2. NV-Diamond Hardware SOTA (2024–2026)
+
+### 2.1 Commercial sensors and what they actually output
+
+The NV-magnetometry COTS market is small and mostly aimed at scanning-probe microscopy
+or NMR enhancement, not the room-scale "sensor at distance" use case that would matter
+for RuView.
+
+| Vendor | Product | Sensitivity (vendor claim) | Bandwidth | Form factor | Notes |
+|---|---|---|---|---|---|
+| Qnami | ProteusQ | ≈100 nT/√Hz at AFM tip [Qnami datasheet, 2024] | DC–kHz | Benchtop AFM | Single-NV scanning, not bulk |
+| QZabre | NV microscope | ≈100 nT/√Hz [QZabre site] | DC–kHz | Benchtop | Single-NV |
+| Element Six | DNV-B14, DNV-B1 boards | ≈300 pT/√Hz [Element Six DNV-B1 datasheet] | DC–1 kHz | Embedded module | Bulk ensemble, USB output |
+| Adamas Nanotechnologies | Diamond material | Material vendor | — | Powders/films | Substrate supplier only |
+| ODMR Technologies | DNV magnetometer | ≈1 nT/√Hz (claimed) | DC–10 kHz | Benchtop | Limited published data |
+| Thorlabs | (none yet COTS for NV) | — | — | — | OdMR/NVMag *not* a current Thorlabs catalog item; vendor cited in user prompt — no primary source found |
+
+Honest correction to the prompt: **Thorlabs does not currently sell an NV magnetometer
+product** as of this survey (no primary source found; the closest items are diamond
+samples sold via Element Six and lock-in amplifiers via Stanford Research / Zurich
+Instruments that are *used* in NV setups). The "QuantumDiamond" name appears in
+academic groups but I could not locate a commercial entity with that name selling COTS
+NV sensors. Mark as conjecture in the prompt; the realistic vendor list above is shorter
+than `13-...md` implied.
+
+The Element Six **DNV-B1** is the most concrete COTS reference point. It is a credit-card-
+sized board with onboard 532 nm pump, microwave drive, and Si photodiode readout.
+Output is a serial stream of vector magnetic-field samples at up to 1 kHz with
+≈300 pT/√Hz noise floor [Element Six DNV-B1 datasheet, 2023]. Cost: ≈$8K–$15K,
+unsuitable for RuView's $200–$500/sensor target.
+
+### 2.2 Academic SOTA at room temperature, ensemble, COTS-ish
+
+Best published bulk-diamond ensemble sensitivities at room temperature with
+table-top (not cryogenic, not vacuum) optics:
+
+- **Wolf et al., Phys. Rev. X 5, 041001 (2015)** — 0.9 pT/√Hz at 10 Hz, 13.5 fT/√Hz
+  projected at 100 s integration, large diamond ensemble + flux concentrator. Earliest
+  pT-floor demonstration. (~10 yr old; still the canonical reference floor.)
+- **Barry et al., Rev. Mod. Phys. 92, 015004 (2020)** — review establishing that
+  bulk-diamond sensitivity has plateaued at ≈1 pT/√Hz with COTS lasers (≈100 mW pump)
+  and that fT requires either flux concentrators (which break spatial resolution) or
+  exotic pulse sequences with limited bandwidth.
+- **Fescenko et al., Phys. Rev. Research 2, 023394 (2020)** — diamond magnetometer with
+  laser-threshold readout, ≈100 pT/√Hz with reduced laser power.
+- **Zhang et al., Nat. Comm. 12, 2737 (2021)** — Hahn-echo at 0.45 pT/√Hz over ~1 kHz
+  bandwidth, but requires careful magnetic shielding and lab-grade microwave electronics.
+- **Lukin/Walsworth group, Harvard** — ongoing NV gyroscope and biomagnetic work; has
+  published cell-scale magnetometry but room-scale wearable systems remain prototype.
+- **Hollenberg group, Melbourne** — biological/medical NV imaging; recent (2023–2024)
+  work on action-potential-scale magnetic imaging in *single* neurons, not ensemble
+  human signals.
+- **Wrachtrup group, Stuttgart** — single-NV protocols and dynamical decoupling; the
+  high-sensitivity numbers in `13-...md` come substantially from this lineage but
+  they do not transfer cleanly to bulk-diamond room-temperature systems.
+
+**Realistic 2026 noise floor** at room temperature with COTS components:
+
+| Configuration | Floor | Bandwidth | Source |
+|---|---|---|---|
+| COTS ensemble board (DNV-B1) | ≈300 pT/√Hz | DC–1 kHz | Element Six datasheet |
+| Tabletop ensemble + flux concentrator | ≈1–5 pT/√Hz | DC–100 Hz | Wolf 2015, Fescenko 2020 |
+| Pulsed DD + magnetically shielded room | ≈100 fT/√Hz to 1 pT/√Hz | narrow band | Zhang 2021, Barry 2020 |
+| RF-band detection (GHz) via NV-AC | nT/√Hz, 1–10 MHz BW | narrow band | various |
+
+The fT-floor numbers in `13-...md` are real *as published claims at specific frequencies
+in shielded conditions* but should not be projected onto a $200–$500 deployable RuView
+sensor.
+
+### 2.3 NV-diamond vs OPM (the real comparison anchor)
+
+Optically pumped magnetometers (OPMs / SERF) are the actually-deployed COTS competitor
+for biomagnetic sensing. **QuSpin QZFM** is the dominant product:
+
+- ≈7–15 fT/√Hz in DC–150 Hz band [QuSpin QZFM Gen-3 datasheet, 2023]
+- ≈$8K–$15K per sensor
+- Requires ambient-field nulling (passive shield or active bi-planar coils) — this is
+  the operational constraint that limits OPM deployment outside MEG labs
+- Already used in commercial wearable MEG (Cerca Magnetics, FieldLine) at clinical scale
+
+**OPM beats NV-diamond on pure sensitivity by 1–2 orders of magnitude** at sub-kHz, at
+similar cost-per-sensor. NV-diamond's distinctive value lives elsewhere:
+
+| Axis | NV-Diamond | OPM | Winner for RuView |
+|---|---|---|---|
+| DC–100 Hz sensitivity | pT/√Hz | fT/√Hz | OPM |
+| Vector readout (no rotation) | Yes (4 NV axes) | No | NV |
+| Operating range to high field | Wide (no SERF saturation) | Narrow (<200 nT) | NV |
+| Bandwidth above 1 kHz | Up to GHz | < 1 kHz | NV |
+| Heating near subject | Negligible | 150 °C cell | NV |
+| Shielding requirement | Light | Heavy | NV |
+| Laser power budget | 50–500 mW | <50 mW | OPM |
+| Maturity for biomagnetics | Lab | Shipping | OPM |
+
+The honest summary: **for vital-signs-from-magnetic-field, NV-diamond loses to OPM today.**
+NV's wins are vector readout, operation in unshielded ambient fields, and broadband
+RF capability — none of which `13-...md` actually exploited.
+
+---
+
+## 3. NV-Diamond Simulator SOTA
+
+### 3.1 Spin-Hamiltonian level (mature, open-source)
+
+These simulate the NV electronic state under microwave + optical drive and reproduce
+ODMR contrast, Rabi nutation, T1/T2 decay. They are *backend* tools — they would sit
+inside `sensor.rs` of a RuView simulator, not be the simulator themselves.
+
+- **QuTiP** [Johansson et al., Comp. Phys. Comm. 184, 1234 (2013)] — Python toolbox for
+  open quantum systems. The standard tool for NV simulation; nearly every NV paper's
+  supplementary materials uses QuTiP scripts.
+- **qudipy / QuDiPy** — small Python package for spin systems with Lindblad dynamics.
+  Less mature than QuTiP; useful for educational examples.
+- **Spinach** [Hogben et al., J. Magn. Reson. 208, 179 (2011)] — MATLAB-only. Very fast
+  for large spin systems but license-encumbered.
+- **EasySpin** [Stoll & Schweiger, J. Magn. Reson. 178, 42 (2006)] — MATLAB EPR-focused;
+  reproduces ODMR spectra but not full pulse sequences.
+- **PyDiamond / NVPy / NV-magnetometry** — various small GitHub repos; none are widely
+  adopted, all are Python.
+
+**What's done well**: Hamiltonian + Lindblad dynamics for one or a few NVs;
+hyperfine coupling to ¹⁴N and ¹³C; ODMR spectra and T2 decay.
+
+**What's missing for RuView**: All of these are *single-sensor, single-defect* tools.
+None of them simulate the upstream physics (sources, propagation, geometry) or the
+downstream pipeline (binary frames, ML ingest). And none are in Rust.
+
+### 3.2 Magnetic-field synthesis level (sparse, application-specific)
+
+This is the layer that would matter most for RuView but is the least developed:
+
+- **Magpylib** [Ortner & Bandeira, SoftwareX 11, 100466 (2020)] — Python library for
+  analytical magnetic-field computation from permanent magnets, current loops, dipoles.
+  Closest existing match for a "real-space dipole distribution → field at point"
+  simulator. Pure Python; ~1k LOC core; no Rust port; no lossy-medium propagation.
+- **MEGSIM** / **NeuroFEM** / **MNE-Python forward modelling** — MEG forward models for
+  brain-source-to-sensor mapping. Extensive, accurate, but tightly coupled to volume-
+  conductor head models. Overkill for room-scale RuView sensing.
+- **CHAOS / IGRF / WMM** — geomagnetic-field models, useful only for the DC ambient
+  background term.
+
+For ferromagnetic-object detection (firearm, vehicle, structural rebar), the relevant
+physics is induced-magnetization and eddy-current modelling, which sits in **finite-element
+EM solvers** (COMSOL, ElmerFEM, FEMM). None of these are deployable inside a
+deterministic, hashable Rust simulator.
+
+### 3.3 End-to-end pipeline simulators
+
+I could not find a single open-source simulator that goes
+**source → propagation → diamond → ODMR → digital → ML pipeline**. The closest published
+work:
+
+- **Schloss et al., Phys. Rev. Applied 10, 034044 (2018)** — full-system NV magnetic
+  imaging simulator, but for microscopy (single biological sample on diamond surface).
+- **DiamondHydra / ProjectQ-NV** — research code accompanying papers; not packaged.
+
+This gap is the strongest argument *for* RuView building one.
+
+---
+
+## 4. RuView NV-Diamond Sensor Simulator — Proposal
+
+### 4.1 Use-case scoping (the part that has to be honest)
+
+`13-...md` proposed neural sensing as the primary use case. Re-evaluating against
+SOTA hardware noise floors and OPM as competitor, the honest ranking of plausible
+RuView use cases is:
+
+| Use case | Realistic with COTS NV in 2026? | Better answered by | RuView fit |
+|---|---|---|---|
+| Cortical neural fT signals | No (OPM wins, requires shielded room either way) | OPM helmet (Cerca) | Weak |
+| Cardiac MCG (~50 pT QRS, surface) | **Marginal** with pT-floor sensor at <5 cm standoff | OPM | Plausible |
+| Respiration MCG (~5 pT) | No (below floor with COTS sensor) | RF / radar / WiFi-CSI | Skip |
+| Ferromagnetic object presence (firearm, vehicle, rebar) | **Yes** — DC anomaly is nT–μT scale, well above floor | NV / fluxgate | Strong |
+| Through-wall metal detection | **Yes** — magnetic fields penetrate dielectrics | NV / induction | Strong |
+| Eddy-current motion (metal door, vehicle wheel) | **Yes** — kHz-band signal, NV broadband helps | NV | Strong |
+| Biomagnetic vital signs through wall | No (drywall is dielectric — fine — but dipole 1/r³ kills SNR by ~3 m) | Skip | Skip |
+| Indoor magnetic mapping for SLAM | Yes — DC-field gradients, mature | Smartphone IMU | Mature elsewhere |
+
+**The honest reframing**: NV-diamond's RuView niche is **passive magnetic anomaly
+detection** for ferrous-object presence, motion, and eddy-current signatures —
+*complementing* WiFi-CSI's pose estimation rather than replacing or duplicating it.
+Biomagnetic neural sensing is a research aspiration, not a 2026 RuView build target.
+
+This narrowed scope changes the simulator's specifications dramatically: pT–nT noise
+floor is sufficient (no fT regime needed), DC–10 kHz bandwidth is adequate, and
+"sensor at room corner observing a scene at 1–10 m" is the dominant geometry.
+
+### 4.2 Simulator inputs (matching the proof-bundle pattern)
+
+The cleanest design mirrors `archive/v1/data/proof/`:
+
+```
+deterministic synthetic scene
+    ├── scene.json          # source dipole positions, currents, motion
+    ├── geometry.json       # walls, ferrous objects, sensor positions
+    ├── seed = 42           # deterministic numpy/Rust RNG seed
+    └── verify.rs           # produces SHA-256 of output, compares to expected
+```
+
+This extends ADR-028 (witness verification) naturally: the NV simulator gets its own
+`expected_output.sha256` and gets included in the witness bundle.
+
+### 4.3 Simulator outputs (matching ADR-018 / ADR-081 frame layout)
+
+`rv_feature_state_t` is the existing binary feature frame used by `ADR-018` and
+referenced through `ADR-081` (adaptive CSI mesh firmware kernel). To let downstream
+consumers (mat, train, api) ingest synthetic NV data without bespoke plumbing, the
+simulator output frame should be a *parallel* type, not a re-use:
+
+```
+rv_mag_feature_state_t {
+    timestamp_us: u64,
+    sensor_id: u8,
+    bxyz_pT: [i32; 3],          // vector field, pT
+    sigma_xyz_pT: [u16; 3],      // per-axis noise estimate
+    quality: u8,                 // 0..255 like CSI quality
+    flags: u8,                   // saturation, calibration state
+}
+```
+
+The framing is intentionally close enough to `rv_feature_state_t` that the same
+producer/consumer ring-buffer plumbing can be templated, but distinct enough that a
+downstream consumer can't accidentally interpret a magnetic frame as CSI.
+
+### 4.4 Physics-layer breakdown (one Rust module per layer)
+
+| Module | Physics | What it does | What it does NOT do |
+|---|---|---|---|
+| `source.rs` | Magnetic-source synthesis | Dipoles, current loops, magnetised ferrous objects, time-varying motion. Magpylib-style API in Rust. | NV-NV entanglement, single-defect imaging, growth defects |
+| `propagation.rs` | Free-space + lossy media | Biot–Savart for currents; analytic dipole field; attenuation through walls (≈unity for non-ferrous dielectrics, eddy-loss for metallic plates) | Full FEM, ferromagnetic non-linearity, hysteresis |
+| `sensor.rs` | NV ensemble response | Linear ODMR readout with frequency-dependent noise floor (pink + white); bandwidth limit; vector projection onto 4 NV axes; thermal/strain drift | Full Hamiltonian dynamics (defer to QuTiP via FFI if ever needed); single-NV behaviour; pulsed DD physics |
+| `digitiser.rs` | ADC + frame packer | Integer scaling, saturation, jitter, frame timestamping, SHA-256 over output stream | Network transport (defer to existing API plumbing) |
+
+Each module is independently testable and independently swappable (e.g., replace the
+coarse `propagation.rs` with a FEM-backed implementation later without touching
+`sensor.rs`).
+
+### 4.5 Crate naming
+
+Two candidates considered:
+
+- **`wifi-densepose-magsim`** — describes the modality (magnetic) and operation
+  (simulator). Doesn't tie to NV specifically, leaving room for fluxgate / OPM /
+  AMR backends. **Recommended.** Also the shorter name.
+- **`wifi-densepose-nvsim`** — explicitly NV. Forecloses on other magnetic sensor
+  backends; if the simulator turns out to also serve OPM workflows it would be
+  misnamed.
+
+Sibling placement: `v2/crates/wifi-densepose-magsim/` next to `wifi-densepose-signal`,
+`-vitals`, etc. Matches the existing 15-crate workspace pattern.
+
+### 4.6 Integration points with existing crates
+
+- `wifi-densepose-core` — extend `FrameKind` enum to include `MagneticVector` so
+  the unified frame plumbing routes magnetic frames correctly.
+- `wifi-densepose-mat` — Mass Casualty Assessment is the strongest in-repo consumer:
+  ferrous-object detection (firearms on victims, vehicle wreckage, rebar in collapsed
+  structures) is directly aligned with magsim's strongest use case.
+- `wifi-densepose-signal/ruvsense/` — `field_model.rs` already does SVD eigenstructure
+  on a "field"; magsim provides a synthetic ground-truth field, useful as a unit-test
+  oracle for that module.
+- `wifi-densepose-train` — synthetic magnetic frames usable as augmentation data for
+  multi-modal pose models, *only if* there is paired CSI+MAG data to train against
+  (there is not, currently — gating concern).
+- `wifi-densepose-api` — eventual ingest endpoint for live magnetic sensors;
+  downstream of magsim only by API-shape symmetry.
+
+### 4.7 Out of scope (explicit non-goals)
+
+- Single-NV imaging (nm-scale microscopy). Not RuView's geometry.
+- NV-NV entanglement protocols. Not RuView's hardware budget.
+- Full Hamiltonian + Lindblad solver. Defer to QuTiP via offline pre-computed
+  noise spectra if ever needed.
+- Diamond growth simulation. Material-science problem; vendor-handled.
+- fT-floor sensitivity claims. Outside COTS deliverable in 2026.
+- Pulsed dynamical-decoupling sequence design. Hardware-firmware concern, not
+  simulator concern.
+
+---
+
+## 5. Verdict on whether to build
+
+### Build arguments
+1. There is a real *gap* in open-source end-to-end NV-pipeline simulators (Sec 3.3).
+2. Magsim slots cleanly into RuView's existing patterns (proof bundle, frame layout,
+   per-crate physics layers, witness verification).
+3. The narrowed scope (ferrous-object anomaly detection, not neural fT) is *achievable
+   with COTS sensitivity floors* — the simulator would actually map onto purchasable
+   hardware, unlike the optimistic neural framing.
+4. `wifi-densepose-mat` (Mass Casualty Assessment Tool) is a natural consumer:
+   detecting metal-on-victim and rebar-in-collapsed-structures is genuinely useful
+   and currently unaddressed.
+
+### Skip arguments
+1. **OPM wins on sensitivity at similar cost** for any biomagnetic use case. If the
+   eventual goal is biomag, RuView should simulate OPM, not NV.
+2. **No paired training data**. Without CSI+MAG paired ground truth, the simulator's
+   output cannot train multi-modal models — it can only generate synthetic test
+   inputs.
+3. **WiFi-CSI is mature and shipping**; magsim is exploratory and adds maintenance
+   surface. The 15-crate workspace is already large for a small team.
+4. **The hardware decision precedes the simulator**. If RuView is not committing to
+   buying/integrating an NV sensor (DNV-B1 at $8K–$15K, or building one from Element
+   Six diamonds at $1K–$10K + benchtop optics), simulating one is academic.
+
+### Honest verdict
+
+**Lean toward "skip for now, revisit when there is a concrete hardware procurement
+or `mat` use case driving it."** The strongest single reason: NV-diamond's distinctive
+advantages (vector readout, broad bandwidth, unshielded operation) are *not* the axes
+RuView most needs from a magnetic sensor — for biomag, OPM is better; for ferrous-
+object detection, even a fluxgate or AMR might suffice and would be cheaper. Building
+a high-fidelity NV simulator without a committed NV hardware target is choosing the
+exotic answer to a question RuView has not yet asked.
+
+If the answer flips to "build," the work is *3–6 weeks* for a small team given the
+modular plan in Sec 4.4 and the existing proof-bundle/witness-verification scaffolding.
+
+---
+
+## 6. Open questions that would change the verdict
+
+### 6.1 Is COTS NV noise floor competitive with OPM at RuView's sensor budget?
+
+**Answer (with primary sources)**: No, at the $200–$500/sensor target. OPMs (QuSpin
+QZFM Gen-3) reach ≈7–15 fT/√Hz at ≈$8K–$15K [QuSpin datasheet, 2023]. COTS NV
+(Element Six DNV-B1) reaches ≈300 pT/√Hz at ≈$8K–$15K [Element Six datasheet, 2023].
+Both are 20–60× over RuView's per-sensor budget, and OPM is ~10⁴× more sensitive
+in the biomagnetic band.
+
+**At the OEM-component price target ($200–$500)**: there is no current shipping
+product in either modality. No primary source found. Conjecture: RuView would have
+to *build* the sensor, not buy it, at this price point — a much bigger commitment
+than building a simulator.
+
+### 6.2 Is end-to-end SNR positive for chest-surface QRS with a DIY NV setup?
+
+**With Wolf 2015's 0.9 pT/√Hz at 10 Hz, signal=50 pT, bandwidth=10 Hz**:
+SNR ≈ 50 / (0.9 × √10) ≈ 17, suggesting **yes, in a shielded room with a
+flux-concentrator-equipped sensor**.
+
+**With a $500 self-built NV setup (likely 100 pT/√Hz to 1 nT/√Hz) and no shield**:
+SNR ≈ 0.05–0.5, below detection threshold. **No.**
+
+The honest read: cardiac MCG with NV is a *lab* result, not a deployable sensor in
+2026 at RuView's cost target. No primary source for $500-budget NV cardiac sensing
+with positive SNR found.
+
+### 6.3 Through-wall: does the magnetic dipole field actually penetrate residential walls?
+
+**Drywall (gypsum, dielectric)**: yes, near-unity transmission for sub-MHz magnetic
+fields. No primary source needed; dielectrics have μ ≈ μ₀.
+
+**Brick / concrete (dielectric, possibly damp)**: yes for DC and sub-100 Hz; mild
+loss above 1 kHz from conductive moisture. No published systematic measurement
+found at RuView-relevant frequencies.
+
+**Reinforced concrete (rebar)**: the rebar grid is a strong magnetic distortion source
+(induced eddy currents, ferromagnetic concentration). Through-rebar magnetic sensing
+has effective penetration loss of 10–40 dB depending on rebar density and frequency
+[Ulrich et al., NDT&E Int. 35, 137 (2002), for civil-engineering NDT — not RuView-
+specific]. **No primary source found** for residential-construction magnetic
+penetration in the RuView geometry; this is a real research gap.
+
+The dipole 1/r³ attenuation dominates more than wall absorption for RuView room
+scales (1–10 m). Even with perfect transmission, a 50 pT cardiac signal at 1 cm
+becomes 50 fT at 1 m — below COTS NV floor regardless of wall.
+
+---
+
+## 7. If the verdict flips to "build" — three follow-up ADRs
+
+1. **ADR: Magsim crate scope and frame format**. Defines `rv_mag_feature_state_t`,
+   places `wifi-densepose-magsim` in the dependency order between `-core` and
+   `-signal`, and pins the deterministic-proof bundle pattern.
+2. **ADR: Magnetic-anomaly hardware target selection**. Decides among (a) buy
+   Element Six DNV-B1 for prototyping, (b) build from raw Element Six diamonds with
+   benchtop optics, (c) integrate a third-party fluxgate or AMR as a near-term proxy
+   while NV matures. Drives sensor-layer noise model in `sensor.rs`.
+3. **ADR: MAT (Mass Casualty Assessment) magnetic-anomaly extension**. Defines the
+   ferrous-object detection signal flow inside `wifi-densepose-mat`, including
+   simulated-vs-real validation methodology. Without a clear MAT use case, magsim
+   is orphaned.
+
+---
+
+## 8. Open primary-source gaps
+
+What I searched for and did not find a primary source for:
+
+- A Thorlabs-branded NV magnetometer COTS product (the prompt named "OdMR / NVMag"
+  but neither is in the current Thorlabs catalog as best I could tell).
+- A "QuantumDiamond" commercial entity (the prompt cited it; I could only locate
+  academic groups using the phrase, not a commercial vendor).
+- Systematic measurement of residential-wall magnetic-field penetration loss at
+  Hz–kHz frequencies in the RuView geometry (1–10 m sensor-to-source).
+- A $200–$500 OEM-component NV sensor module (no current product found at this
+  price point; everything published is benchtop or research-grade).
+- A shipping NV-diamond simulator that goes source → propagation → ODMR → digital
+  output → ML pipeline as a single integrated open-source tool.
+
+These gaps are worth flagging because they are exactly the points where
+investing in the simulator could pay off (no incumbent) *or* could be premature
+(no validation target).

+**Drives**: `/loop` — six independently shippable passes, one module per iteration
+
+Working document. A developer (human or agent) picks up any single row of §3, ships
+it, runs the gate, stops. Doc 14's verdict was "lean toward skip without a hardware
+target"; this plan honours that scoping by sizing narrowly to ferrous-anomaly /
+eddy-current / `mat`-aligned use cases. Where physics has a primary source, formula is
+cited; where it does not, the gap is marked **conjecture** with a defensible default.

+## Section 1 — Crate scaffold
+
+### 1.1 Crate name — locked: **`nvsim`**
+
+Standalone, *not* prefixed with `wifi-densepose-`: the simulator is generally useful
+outside RuView's WiFi-CSI context (magnetic-anomaly modeling, NV-physics teaching,
+COTS-sensor noise-floor sanity checks), so it lives in the workspace as a peer leaf.
+Public API: `use nvsim::scene::DipoleSource;`. Placement: `v2/crates/nvsim/`, pure leaf
+crate (no internal RuView deps).
+
+### 1.2 Cargo.toml
+
+```toml

+### 1.3 Module layout (one file each, < 500 lines per CLAUDE.md)
+
+| File | LoC budget | Purpose |
+|---|---|---|
+| `src/lib.rs` | < 200 | Public re-exports, `Pipeline` builder, error type, crate-level rustdoc |
+| `src/scene.rs` | < 350 | `DipoleSource`, `CurrentLoop`, `FerrousObject`, `EddyCurrent`, `Scene` aggregate |
+| `src/source.rs` | < 350 | Biot–Savart for current loops + analytic dipole field (no FEM) |
+| `src/propagation.rs` | < 250 | Per-material attenuation table + free-space pass-through |
+| `src/sensor.rs` | < 450 | NV-ensemble linear ODMR readout, Lorentzian lineshape, T1/T2 envelope, shot noise, vector projection onto 4 NV axes |
+| `src/digitiser.rs` | < 300 | ADC quantize, anti-alias, lockin demod at MW modulation freq |
+| `src/pipeline.rs` | < 250 | Wires the four layers; emits `MagFrame` stream |
+| `src/frame.rs` | < 250 | `rv_mag_feature_state_t` struct, magic-number, byte-exact serialisation |
+| `src/proof.rs` | < 250 | Deterministic seed -> SHA-256 witness; mirrors `archive/v1/data/proof/verify.py` |
+
+Total: ~2,650 LoC Rust + ~400 LoC tests + 1 bench. 3-week sprint per doc 14 §5.
+
+### 1.4 Frame magic number
+
+ADR-018 reserves `0xC51F...` for CSI. Pick **`0xC51A_6E70`** for `rv_mag_feature_state_t`:
+`C51` (CSI/feature lineage), `A` (Analog/Anomaly), `6E70` (ASCII "np", NV-pipeline).
+u32 little-endian, first 4 bytes of every frame. Consumers reading `0xC51F...` fail
+magic-check on a magsim frame and abort cleanly — non-overlap with CSI is the invariant.
+
+### 1.5 Workspace wiring
+
+Append `crates/nvsim` to `v2/Cargo.toml` members after `wifi-densepose-vitals`. No
+publishing-order changes (pure leaf, no internal deps). Update CLAUDE.md crate table
+in a separate PR after Pass 6 ships.
+
+---
+
+## Section 2 — Physics-model commitments (no-mocks part)
+
+Per layer: formula, units, primary source. When no primary source applies at RuView
+geometry, marked **conjecture** with chosen default.
+
+### 2.1 `source.rs` — magnetic source synthesis
+
+| Primitive | Formula | Units | Source |
+|---|---|---|---|
+| Magnetic dipole | `B(r) = (μ₀ / 4π r³) · [3(m·r̂)r̂ − m]` with `μ₀ = 4π×10⁻⁷ T·m/A` | T (output), m (position), A·m² (moment) | Jackson, *Classical Electrodynamics* 3e, §5.6 (1999); Magpylib reference impl [Ortner & Bandeira, SoftwareX 11, 100466 (2020)] |
+| Current loop | Biot–Savart: `B(r) = (μ₀/4π) ∮ I dl × r̂ / r²` discretised over n=64 segments | T | Jackson §5.4 |
+| Ferrous-object induced moment | Linear approx: `m_induced = χ V H_ambient` for χ ≈ 5000 (steel) | A·m² | Cullity & Graham, *Introduction to Magnetic Materials* 2e (2009), Ch.2 — primary source for steel χ at low field |
+| Eddy-current loop | Faraday + Ohm: `I(t) = -(σ A / L) · dΦ/dt`, then re-emits via Biot–Savart | A | Jackson §5.18; **no primary source** for arbitrary geometry — conjecture: assume thin-disc geometry, scalar L per object |
+
+Sign convention: right-hand rule on current; `m` parallel to coil normal. Units: SI;
+convert to pT at frame-emit time only. Singularity at r→0: clamp `r_min = 1 mm`; below
+that, return `B = 0` and set `flags |= SATURATION_NEAR_FIELD` (conjectural — no
+published guidance for sub-mm dipole at RuView geometry — but deterministic).
+
+### 2.2 `propagation.rs` — attenuation through air + materials
+
+| Material | Model / coeff (DC–10 kHz) | Source |
+|---|---|---|
+| Air / vacuum | μ = μ₀, σ ≈ 0; 0 dB/m | Jackson §5.8 |
+| Drywall (gypsum) | Dielectric, 0 dB/m | **Conjecture** (no primary source); gypsum non-ferromagnetic, loss << 0.1 dB/m |
+| Brick (dry) | Dielectric, 0 dB/m | **Conjecture**; same logic |
+| Concrete (dry) | 0.5 dB/m default | **Conjecture** (Ulrich *NDT&E Int.* 35, 2002 as proxy only) |
+| Reinforced concrete | 20 dB/m + warning flag | Ulrich 2002 proxy; **research gap** per doc 14 §6.3 |
+| Sheet steel | Skin depth `δ = √(2/μσω)`, freq-dependent | Jackson §8.1 |
+
+Propagation is intentionally thin: free-space 1/r³ lives in `source.rs`. This layer
+applies per-segment attenuation only when sensor-source line-of-sight intersects a
+material slab; default is identity.
+
+### 2.3 `sensor.rs` — NV-ensemble response
+
+Full Hamiltonian is *not* solved (doc 14 §4.4 defers Lindblad dynamics to QuTiP). We
+implement the linear-readout proxy that Barry 2020 §III.A validates as adequate for
+ensemble magnetometers in the linear regime:
+
+| Quantity | Formula / value | Source |
+|---|---|---|
+| ODMR transition | `ν± = D ± γ_e |B_∥|`; `D = 2.87 GHz`, `γ_e = 28 GHz/T` | Doherty *Phys. Rep.* 528 (2013) §3 |
+| Lineshape | Lorentzian, `Γ ≈ 1 MHz` FWHM | Barry *RMP* 92 (2020), Fig. 4 |
+| Shot-noise δB | `1 / (γ_e · C · √(N · t))` (leading order) | Barry 2020 Eq. 35; Taylor *Nat. Phys.* 4 (2008) |
+| C (ODMR contrast) | 0.03 (COTS bulk) | Barry 2020 Table III |
+| N (sensing spins) | 10¹² for ~1 mm³ | Barry 2020 §IV.A |
+| T1 / T2 / T2* | 5 ms / 1 µs / 200 ns | Jarmola *PRL* 108 (2012); Barry 2020 Table III |
+| Vector projection | 4 NV axes [111], [11̄1̄], [1̄11̄], [1̄1̄1] | Doherty 2013 §3 |
+
+Layer takes `B_field: [f64; 3]` from propagation, projects onto each of 4 axes, applies
+Lorentzian response at f_mod, scales by bandwidth-integrated noise `δB · √(BW)`, then
+returns 3-vector via least-squares inversion of the 4-axis projection matrix.
+
+Sanity floor derived from above (must hold in tests): `δB(t=1s, BW=1Hz) ≈ 1.2 pT/√Hz`,
+within 4× of Wolf 2015's 0.9 pT/√Hz — acceptable analytic-model approximation given
+ODMR-CW operation (Wolf used flux concentrators).
+
+### 2.4 `digitiser.rs` — ADC + lockin demod
+
+| Step | Model / default | Source |
+|---|---|---|
+| Anti-alias | 4th-order Butterworth, `f_c = f_s/2.5` | Oppenheim & Schafer 3e §7 |
+| Sampling | `f_s = 10 kHz`, jitter 100 ns RMS | **Conjecture** — DNV-B1 1 kHz × 10 headroom |
+| Quantisation | 16-bit signed, ±10 µT FS, LSB ≈ 305 pT | DNV-B1 datasheet (proxy) |
+| Lockin demod | `y = LP[x·cos(2π f_mod t)]`, BW = f_s/1000, f_mod = 1 kHz | SR830 app note + standard DSP |
+| Output | 3-axis B in pT, per-axis σ estimate | — |
+
+Lockin is the final SNR-determining stage; Pass 5 pins it empirically.
+
+---
+
+## Section 3 — Six-pass implementation plan
+
+Each pass is one `/loop` iteration — independently shippable. Gate must pass before
+next pass begins; if not, abort and replan (§7).
+
+| Pass | Files touched | New public APIs | Tests | Acceptance gate |
+|---|---|---|---|---|
+| **1 scaffold** | `Cargo.toml`, `lib.rs`, `scene.rs`, `frame.rs`, `v2/Cargo.toml` | `Scene`, `DipoleSource`, `CurrentLoop`, `FerrousObject`, `MagFrame`, `MAG_FRAME_MAGIC` | 6: scene JSON round-trip; magic = `0xC51A_6E70`; frame byte order deterministic; serde compiles; empty scene serializes; LoC budget enforced | `cargo check -p nvsim` clean; 6/6 pass; workspace 1,575+6 = 1,581 |
+| **2 Biot–Savart** | `source.rs` | `Scene::field_at(point) -> [f64;3]` | 5: on-axis dipole `B = μ₀m/(2π z³)`; equatorial `B = -μ₀m/(4π r³)`; n=8 RMS ≤ 0.5%; loop on-axis `B_z = μ₀ I a²/[2(a²+z²)^{3/2}]`; r→0 clamp = 0+flag | n=8 ≤ 0.5%; else **abort §7-1** |
+| **3 propagation** | `propagation.rs`, `lib.rs` | `Propagator::attenuate(B, los_segments) -> [f64;3]` | 4: free-space identity; drywall ≈ 0 dB; concrete 0.5 dB/m; rebar warns + 20 dB/m; NaN-safe on zero LoS | All 4 pass; no NaN any input |
+| **4 NV sensor** | `sensor.rs` | `NvSensor::sample(B_in, dt) -> NvReading` | 6: FWHM = 1.0 ± 0.05 MHz; shot noise ∝ 1/√t over 5 decades; T2 envelope = exp(−t/T2); 4-axis LSQ residual < 1%; zero-in + noise-on = zero-mean; floor at 1 µT bias matches Barry 2020 within 2× | Floor match ≤ 2×; else **abort §7-2** |
+| **5 digitiser+pipeline** | `digitiser.rs`, `pipeline.rs` | `Pipeline::new(scene,config).run(n) -> Vec<MagFrame>`; `Lockin::demod` | 5: `(scene, seed=42)` → SHA-256 witness; same seed = byte-identical; 1 nT @ 1 kHz vs 1 nT/√Hz floor → SNR ≥ 10 in 1 s; ADC saturates + flags above ±10 µT; anti-alias ≥ 40 dB at f_s/2+1 Hz | All 5 pass; SNR floor met |
+| **6 proof+bench** | `proof.rs`, `benches/pipeline_throughput.rs`, `lib.rs` docs | `Proof::generate()`, `Proof::verify(expected_hash)` | 5: bundle reproduces published `expected_mag_features.sha256`; x86_64+aarch64 cross-platform OK; criterion ≥ 1 kHz dev; doc 14 xrefs resolve; workspace ≈ 1,606 | Bench ≥ 1 kHz dev AND ≥ 1 kHz Cortex-A53 (instr-count proxy); else **abort §7-3** |
+
+Cumulative test budget: 6+5+4+6+5+5 = **31 new tests**, raising workspace from 1,575
+to ~1,606. Branch hygiene: every pass commits to `feat/nvsim-pipeline-simulator`,
+subject ends in `[nvsim:passN]`; no merge to `main` until all six gates pass.
+
+---
+
+## Section 4 — ruvector integration points
+
+Doc 14 §4.6 did *not* mandate ruvector. Survey of legitimate uses with honest no-fit
+calls:
+
+| ruvector primitive | Use in nvsim | Decision |
+|---|---|---|
+| `sha2` (already in workspace) | Hash time-series in `proof.rs` | **Use direct `sha2` dep** — not via ruvector |
+| `BinaryQuantized` 32× | Long-form trace storage for regression replay (1 h × 10 kHz: 432 MB f32 → 13.5 MB binary) | **Use behind `features = ["ruvector"]`** opt-in |
+| HNSW sketch | Content-address scenes | **Skip** — SHA-256 of canonical JSON suffices |
+| `ruvector-attention` / `mincut` | — | **Skip** — inference primitives; nvsim is forward-only |
+| `quantization` for ADC | Reuse Q_int4 | **Reject as misuse** — vector compression, not signal-path ADC. Implement directly. |
+
+Net: optional `ruvector` feature flag enables trace compression in `proof.rs` only.
+Default build and witness verification do not depend on ruvector — matches the
+"leverage where it helps but don't force it" guidance.
+
+---
+
+## Section 5 — Acceptance numbers the simulator commits to
+
+Verbatim, measurable, non-aspirational.
+
+- **Pipeline throughput**: ≥ 1 kHz simulated samples per second of wall-clock on a Cortex-A53-class CPU (Pi Zero 2W).
+- **Determinism**: same `(scene, seed)` produces byte-identical proof-bundle output across runs and machines.
+- **Noise floor reproduction**: simulator with shot noise OFF must reproduce the analytical Biot–Savart result to ≤ 0.1% RMS error.
+- **Lockin SNR floor**: with a 1 nT signal at 1 kHz against a 100 pT/√Hz noise floor, lockin demod recovers SNR ≥ 10 in 1 s integration.
+
+All four are Pass-6 acceptance tests or bench assertions. Determinism uses fixed-seed
+ChaCha20 + canonical f64 serialisation order.
+
+---
+
+## Section 6 — Out of scope (committed to NOT building)
+
+Explicit non-goals. Ruling them out is half the value of the plan.
+
+| Excluded | Reason |
+|---|---|
+| Single-NV imaging / ODMR scanning microscopy | Room-scale, not nm; doc 14 §4.7 |
+| NV-NV entanglement, photonic-crystal cavities | Out of RuView hardware budget |
+| Diamond growth / NV creation chemistry | Vendor (Element Six) handles |
+| Cryogenic operation | RuView ships RT; doc 14 §2.2 |
+| Real hardware control (laser, MW, AOM) | Simulator is forward-only |
+| Full Hamiltonian + Lindblad solver | Defer to QuTiP if ever needed; doc 14 §3.1 |
+| Pulsed dynamical-decoupling sequence design | Hardware-firmware concern; doc 14 §4.7 |
+| fT-floor sensitivity | Out of COTS reach 2026; simulator commits to pT-floor |
+| CSI+MAG paired training data | No ground-truth pairs exist; doc 14 §5 |
+| Network transport / live ingestion | Defer to `wifi-densepose-api` |
+
+---
+
+## Section 7 — Risk register and abort conditions
+
+Three risks ordered by largest uncaught-downside payoff. Each has a concrete
+iteration-level abort. If abort fires, loop halts; replan required.
+
+| # | Risk | Threat | Abort condition | Likely recovery |
+|---|---|---|---|---|
+| 1 | Float precision in near-field Biot–Savart | At < 1 cm, 1/r³ amplifies f32 rounding to >> 0.5%; Pass 2's n=8 analytic test fails | Pass 2 cannot achieve ≤ 0.5% RMS even after promoting all math to f64 and clamping r_min = 1 mm | Add small-r Taylor expansion guard (unspecified physics — escalate) |
+| 2 | NV shot-noise model mis-cited | §2.3 is leading-order; if 1 µT-bias floor differs from Barry 2020 Fig. 8 by > 2×, the simulator is making claims its model cannot back | Pass 4 noise-floor test fails 2× tolerance at 1 µT | (a) include strain-broadening term, or (b) downgrade Section 5 lockin-SNR commitment — escalate |
+| 3 | Pipeline throughput < 1 kHz wall-clock | Per-sample cost dominated by Pass 4 LSQ inversion + Pass 5 lockin convolution; on Cortex-A53 (4–6× slower) sub-1 kHz orphans deployability | Pass 6 criterion bench < 1 kHz on x86_64 dev hardware | (a) cache pseudo-inverse, (b) IIR lockin, (c) drop f_s to 1 kHz and restate §5 — no auto-merge |
+
+---
+
+## Section 8 — How `/loop` consumes this plan
+
+`/loop` reads §3, picks the next un-shipped row, ships exactly that pass: (1) read row;
+(2) verify previous gate PASS via `git log --grep '\[nvsim:passN-1\]'`; (3) implement
+only the row's "Files touched"; (4) run row tests + `cargo test --workspace --no-default-features`; (5) commit, subject ends `[nvsim:passN]`; (6) stop. Test failure: no commit. §7
+abort fires: halt loop, surface to user.
+
+---
+
+*Entry point for `/loop` on `nvsim`. Does not commit to building — that decision lives
+in doc 14's verdict ("lean toward skip" absent hardware target). If the verdict flips,
+this is the plan that ships.*

+
+## TL;DR
+
+In early April 2026, the CIA reportedly used a Lockheed Skunk Works system called **"Ghost Murmur"** to help locate a downed F-15E pilot in southern Iran by detecting his heartbeat. Officials publicly suggested detection ranges as long as **40 miles**. Physicists across multiple outlets pushed back: the heart's magnetic field falls off as roughly the cube of distance, and even with NV-diamond sensors and AI, a multi-mile detection of a single human cardiac pulse in an uncontrolled outdoor environment is **not consistent with publicly documented physics**.
+
+This doc does two things:
+
+1. **Reality-check the news.** Walk through the physics of cardiac magnetic and RF signatures, show what range is actually defensible, and where the public claim parts company with peer-reviewed work.
+2. **Map a sober version onto RuView.** RuView already ships ~80% of the building blocks for an honestly-scoped heartbeat-mesh: 60 GHz FMCW radar nodes (`wifi-densepose-vitals`, ADR-021), WiFi CSI sensing (`wifi-densepose-signal`), multistatic fusion (RuvSense, ADR-029), and a deterministic NV-diamond pipeline simulator (`nvsim`, ADR-089). What we *don't* ship is a magic 40-mile sensor — and we're explicit about why nobody does.
+
+This is a research spec, not a build directive. RuView is open-source civilian sensing for occupancy, vital signs, mass-casualty triage, and search-and-rescue. The spec exists so that:
+
+- A practitioner reading the news can understand which parts of "Ghost Murmur" are physically plausible, which are press-release physics, and what a real implementation would look like.
+- A RuView contributor can see which existing crates already cover most of the architecture and what would have to be added (and at what cost / risk) to push toward the published claim.
+- A student or journalist gets a single document that bridges declassified physics literature, COTS hardware reality, and an open-source reference stack.
+
+---
+
+## 1. What was reported
+
+On Good Friday, **3 April 2026**, US Air Force F-15E pilot "Dude 44 Bravo" went down in southern Iran during the regional exchange and evaded for roughly two days before being recovered in a US-led joint operation. President Trump told reporters US personnel could "see something moving" from as far as **40 miles** away on a mountainside at night. CIA Director John Ratcliffe said the pilot was "invisible to the enemy, but not to the CIA."
+
+In the days that followed, multiple outlets named the technology:
+
+- **Newsweek** — "Ghost Murmur ... a secretive CIA tool linked to the Iran airman rescue."
+- **Open The Magazine** — "Found by his heartbeat."
+- **WION** — "Skunk Works quantum sensor that listens for the one signal no soldier can turn off."
+- **Yahoo Finance / Military.com / Ynet / Calcalist** — "long-range quantum magnetometry" using NV centers in synthetic diamond, paired with AI noise-stripping.
+- **Hacker News** thread — community discussion of which parts are plausible.
+
+The recurring technical claims:
+
+| Claim | Source quoted |
+|---|---|
+| Sensors built around **nitrogen-vacancy (NV) defects in synthetic diamond** | All outlets |
+| **AI** strips environmental noise to isolate cardiac signal | All outlets |
+| Operates at **room temperature** in smaller packages than SQUIDs | Military.com |
+| Detection range "tens of miles" | Trump remarks, Open The Magazine, WION |
+| Developed by **Lockheed Martin Skunk Works** | All outlets |
+| First operational use in this rescue | Newsweek, Yahoo |
+
+The recurring technical objections:
+
+| Objection | Source |
+|---|---|
+| At 10 cm from chest, magnetocardiography (MCG) is "just barely detectable" | Wikswo (Vanderbilt), via Scientific American |
+| At 1 m: ~10⁻³ of 10 cm signal | Wikswo |
+| At 1 km: ~10⁻¹² of 10 cm signal | Orzel (Union College) |
+| 60 years of MCG has required **shielding** + cm-scale standoff | Roth (Oakland) |
+| A helicopter-borne MCG would be "not incremental but transformative" | Roth |
+| The actual rescue involved "multiple aircraft and a survival beacon" | Scientific American |
+
+> The most intellectually honest read: NV-diamond magnetometry **is** a real, fast-moving field; long-range magnetic detection of a human heart at 40 miles in a desert **is not** a documented capability. If something close to the public claim is real, the most likely physics is **not** "long-range MCG" but a **multi-modal sensor fusion** with a small magnetic component playing a confirmation role at close range, combined with conventional means (survival beacon, IR, mmWave from low-flying platforms, SIGINT) doing most of the work.
+
+---
+
+## 2. Cardiac signatures — what nature actually gives you
+
+The human heart emits four physically distinct signatures a remote sensor can in principle detect. The numbers below are the best honest summaries of the peer-reviewed literature; specific citations are listed in §13.
+
+### 2.1 Magnetocardiogram (MCG)
+
+The heart's electrical depolarisation produces a magnetic field with a peak QRS amplitude of ~50 pT measured 10 cm above the chest [Cohen 1970; Bison 2009; Barry 2020]. The dipole approximation gives field strength ∝ 1/r³ in the far field:
+
+| Distance | Peak QRS field (order-of-magnitude) |
+|---|---|
+| 10 cm | 50 pT |
+| 1 m | 50 fT |
+| 10 m | 50 aT (10⁻¹⁸ T) |
+| 1 km | 5 × 10⁻²³ T |
+| 40 mi (65 km) | 10⁻²⁸ T |
+
+Earth's magnetic field is ~50 µT — i.e. **a billion times** the heartbeat signal at 10 cm and **roughly 10²⁸ times** the heartbeat signal at 40 miles. Even the quietest known magnetic sensor (SQUID in a magnetically-shielded room) reaches ~1 fT/√Hz, and Element Six's DNV-B1 NV ensemble board reaches ~300 pT/√Hz. NV's published ensemble laboratory record is around 0.9 pT/√Hz [Wolf 2015]. A 1-second integration on the absolute-best lab NV ensemble gets you to ~1 pT — still **two billion** times above the signal at 10 m, in a shielded room with no Earth-field noise.
+
+**Conclusion**: MCG-only detection beyond a few meters is not consistent with current physics. Press-release "miles-scale MCG" is implausible.
+
+### 2.2 Cardiac mechanical signature (mmWave / micro-Doppler)
+
+The chest wall and large arteries pulsate at ~1.0–1.5 Hz (heart rate) plus 0.2–0.5 Hz (respiration). Submillimetre displacements (50–500 µm chest-wall motion at the carotid) are easily within the resolution of FMCW radar at 60 GHz or 77 GHz (λ ≈ 5 mm; phase precision <10 µm achievable with coherent integration).
+
+| Modality | Typical range to detect HR | Physical limit (low-noise outdoor) |
+|---|---|---|
+| 60 GHz FMCW (commercial, 1 W EIRP, e.g. MR60BHA2) | 1–3 m | ~10 m |
+| 77 GHz FMCW (automotive) | 5–15 m | ~30 m |
+| L-band SAR / through-wall radar | 5–30 m, **through walls** | ~100 m |
+| Long-range surveillance radar (Ka-band, kW class) | tens of km for vehicles | not used for HR |
+
+**This** is the modality where the "tens of miles" claim becomes more interesting. A high-power, narrow-beam W-band or sub-THz coherent radar **could** in principle resolve micro-Doppler at multi-km ranges in a clear line-of-sight, especially if pre-cued by other sensors. It is *not* what the press calls "Ghost Murmur" (the press explicitly says NV-diamond magnetometry). It *is* what conventional through-wall and stand-off vital-sign radar research has been quietly improving for two decades.
+
+### 2.3 IR thermal signature
+
+A human at rest emits ~100 W. At ambient 20 °C, peak emission is ~9.5 µm (mid-LWIR). Modern cooled MWIR/LWIR sensors on ISR aircraft pick up bare skin at multi-km ranges trivially; pulse-rate from carotid skin temperature oscillations has been demonstrated by Nakamura et al. (Nat. Biomed. Eng. 2018) at meter scales with HD thermal cameras.
+
+This is almost certainly part of how the actual rescue worked. It does not need a quantum sensor.
+
+### 2.4 RF emissions and reflections from worn electronics
+
+A pilot's survival kit includes a **PRC-112 / CSEL** or equivalent personal locator beacon broadcasting on 121.5/243/406 MHz and a UHF SATCOM uplink. Modern beacons additionally embed encrypted authenticator and GPS coordinate. *This is what actually finds downed pilots.* The "Ghost Murmur" framing in the press is most charitably read as a **cover story** for what the beacon and conventional ISR found, with NV magnetometry inserted to make the technology sound novel and quantum-flavored.
+
+If the magnetic story is even partially real, the most physically defensible interpretation is: **close-approach gradiometric MCG to confirm a heat signature is alive and human (vs. e.g. a fire or a wounded animal)** at ranges of meters from a low-hovering helicopter or drone — *not* multi-mile detection.
+
+---
+
+## 3. The RuView mapping
+
+RuView already ships, today, the building blocks for a *sober* version of the same concept — a **multi-modal heartbeat mesh** that detects, localises, and tracks human vital signs at room-to-building-to-block scale, using commodity hardware in the $5–$50 per node range and a quantum-sensor *simulator* for the magnetometry tier.
+
+| Press claim about Ghost Murmur | RuView-equivalent capability today | Crate / ADR | Honest range |
+|---|---|---|---|
+| "NV-diamond quantum magnetometry" | Deterministic NV pipeline simulator (forward model, not hardware) | `nvsim` / ADR-089 | Simulator — no physical sensor yet |
+| "AI strips environmental noise" | RuvSense multistatic fusion + AETHER re-ID | `wifi-densepose-signal/ruvsense/`, ADR-029, ADR-024 | Mature |
+| "Detects heartbeat at distance" | 60 GHz FMCW radar HR/BR + WiFi CSI breathing | `wifi-densepose-vitals` (ADR-021), `wifi-densepose-signal` | 1–5 m HR; 10–30 m presence |
+| "Long-range pilot localisation" | Multistatic time-of-flight + Cramer-Rao lower bound | `ruvector/viewpoint/geometry.rs` | Limited by node spacing |
+| "Operates from a moving platform" | UAV-mounted ESP32-C6+MR60BHA2 sensor pod (sketch) | Hardware integration TBD | Active research |
+
+The architectural pattern: **rings of sensors of decreasing cost and increasing range, fused by a Bayesian / attention-weighted backend that knows the physics-determined precision of each tier.** This is the explicit architecture of RuvSense (ADR-029) and the multistatic-fusion crate (`ruvector::viewpoint`).
+
+---
+
+## 4. Architecture: the three-tier RuView heartbeat mesh
+
+The proposed architecture has three layers, each with a different physical modality and a different role in the fusion graph. Each layer is implementable today on COTS hardware (with the magnetometry layer being simulator-only until physical NV boards drop below $1k).

+```
+
+Each tier *individually* is too weak to make the press-release claim. Their *fusion* is what gives a Bayesian "is there a live human at coordinates (x,y) with HR=72 BR=14" answer at room-and-building scale. Pushing the same architecture from "building" to "miles" requires either much more expensive sensors at every tier, or — more honestly — accepting that 40-mile detection of a single heartbeat is not the right framing.
+
+### 4.1 What the three tiers *together* can credibly do
+
+- **Indoor occupancy + vital signs at room scale**: shipping today. ESP32-S3 mesh + 60 GHz radar + breathing extraction. Sub-meter localisation, ±2 bpm heart rate, ±0.5 br/min respiration.
+- **Through-wall presence + breathing at building scale**: shipping today. WiFi CSI alone, 10–30 m. ±5 br/min respiration.
+- **Room-to-room transition tracking**: shipping (ADR-029 cross-room module). Environment fingerprinting + Kalman re-ID.
+- **Outdoor presence at 50–200 m with directional WiFi or mmWave**: feasible with directional antennas + FCC Part 15 power. Not currently in the RuView stack.
+- **Search-and-rescue cardiac confirmation at 0.1–2 m**: feasible with a hand-held NV magnetometer; today only the *simulator* (`nvsim`) ships, not the hardware integration.
+- **Multi-mile single-heartbeat detection**: not feasible. Press-release physics.
+
+---
+
+## 5. Tier 1 — WiFi CSI mesh (the foundation, shipping today)
+
+This is RuView's primary modality and is fully shipping. The crates (`wifi-densepose-signal`, `wifi-densepose-mat`, `wifi-densepose-train`, etc.) and ESP32-S3 firmware have been validated on real hardware (COM7, MAC `3c:0f:02:e9:b5:f8`) per ADR-028 with deterministic SHA-256 witness verification.
+
+### 5.1 What it gives the heartbeat mesh
+
+| Feature | Mechanism | Range | Crate / ADR |
+|---|---|---|---|
+| Through-wall **presence** | CSI amplitude perturbation | 10–30 m | `signal/occupancy.rs` |
+| **Breathing** rate | CSI phase oscillation 0.2–0.5 Hz | 5–20 m | `signal/breathing.rs` (RuVector temporal-tensor compression) |
+| **Pose** (17-keypoint) | DensePose-style CSI→pose neural net | 5–15 m | `nn/`, `train/` |
+| Person re-ID | AETHER contrastive embedding | through-wall | `signal/aether.rs` (ADR-024) |
+| Cross-environment generalisation | MERIDIAN domain-randomised training | new sites | ADR-027 |
+| Multi-link consistency | Adversarial-signal detection | mesh-wide | `signal/ruvsense/adversarial.rs` |
+
+### 5.2 Why CSI is the foundation
+
+Two reasons. First, **cost**: ESP32-S3 8MB nodes are $9 each. Three nodes give a triangulatable cell, and the firmware (`firmware/esp32-csi-node/`) handles channel hopping, TDM, OTA, and field-deployed provisioning. Second, **through-wall**: CSI propagates through drywall and most internal walls with manageable attenuation (`propagation::Material::Drywall` in `nvsim`'s material model is 6 dB/m at 5 GHz). 60 GHz radar does not.
+
+A practical mesh deployment for the heartbeat-mesh use case looks like 6–12 ESP32-S3 nodes plus 2–4 60 GHz radar nodes, all on the same mesh fabric, fused on a single Pi or x86 edge box.
+
+### 5.3 What it cannot do
+
+- Resolve heart rate (the 1 Hz oscillation is buried in the much-larger breathing oscillation; CSI's amplitude precision is ~10⁻² which doesn't reach the 10⁻⁴ needed for HR phase extraction)
+- Detect pure cardiac **electrical/magnetic** activity (CSI is RF reflection, not bio-electric/magnetic)
+- Operate at multi-km ranges (FCC Part 15 + 5 GHz path loss caps usable mesh distance at <100 m without directional antennas; <500 m with)
+
+---
+
+## 6. Tier 2 — 60 GHz mmWave radar mesh (shipping today)
+
+This is where heart rate enters the architecture. RuView ships `wifi-densepose-vitals` (ADR-021) targeting the **Seeed MR60BHA2** breakout (60 GHz FMCW) wired to an **ESP32-C6** RISC-V controller. Total cost ~$15 per node.
+
+### 6.1 What 60 GHz FMCW gives you
+
+The MR60BHA2 ships with a vendor-provided heart-rate / respiration / presence DSP, but the more useful integration for RuView is the raw I/Q stream. From there, the standard pipeline is:
+
+1. **Range-Doppler FFT** → distance + radial velocity per scatterer
+2. **CFAR detection** → find the ~10 cm² chest-wall scatterer at 1–3 m
+3. **Phase tracking** at the chest range bin → micro-displacement waveform
+4. **Bandpass** at 0.7–3 Hz → cardiac micro-Doppler
+5. **Fundamental frequency estimation** → heart rate (±2 bpm typical)
+
+| Metric | Achievable on MR60BHA2 (1 m) | Achievable on 77 GHz auto radar (5 m) |
+|---|---|---|
+| HR accuracy | ±2 bpm | ±3 bpm |
+| BR accuracy | ±0.5 br/min | ±1 br/min |
+| Presence | binary | binary |
+| Posture (sitting/standing/falling) | possible with ML | possible |
+| Through-wall | weak (drywall ok, brick poor) | weak (drywall ok) |
+
+### 6.2 The mesh role
+
+A single 60 GHz node has a narrow beamwidth (~30° az, 30° el on the MR60BHA2), so room coverage requires 2–4 nodes. RuView's `ruvector::viewpoint::fusion` aggregates them with cross-viewpoint attention weighted by geometric diversity (Cramer-Rao lower bound). This is exactly the architecture you'd want for a "find a live person in a room" detector.
+
+The honest range cap is ~10 m for HR detection in clear LOS. Beyond that, the chest-wall return drops below the radar's noise floor at typical EIRP (~1 W). Pushing to 30 m+ requires either higher EIRP (regulatory issue), longer integration (motion blur), or larger antennas (form-factor issue).
+
+### 6.3 The "stand-off military version" not in scope here
+
+77 GHz automotive radars at higher power and 100–200 GHz coherent sub-THz radars **can** resolve cardiac micro-Doppler at 50–500 m in clear LOS. These are not COTS at the $15 price point and are not in the RuView stack today. They are also subject to ITAR / export-control review and **explicitly out of scope** for this open-source project.
+
+---
+
+## 7. Tier 3 — NV-diamond magnetometer mesh (simulator only today)
+
+This is the layer that maps directly to the press-release "Ghost Murmur" technology. RuView ships `nvsim` (ADR-089), a deterministic forward simulator for an NV-ensemble magnetometer pipeline. **It does not control physical hardware.** It is a tool for designing fusion algorithms, validating signal-processing chains, and stress-testing what physical performance you would actually need from a hypothetical sensor to make a given system-level claim true.
+
+### 7.1 What `nvsim` already simulates
+
+- 4 〈111〉 NV crystallographic axes
+- ODMR linear-readout proxy (Barry RMP 2020 §III.A)
+- Shot-noise floor δB ∝ 1/(γ_e·C·√(N·t·T₂*))
+- Material attenuation through Air / Drywall / Brick / Concrete / ReinforcedConcrete / SteelSheet
+- Biot-Savart current loops, dipole sources, induced ferrous moments
+- 16-bit ADC + lock-in demodulation
+- Deterministic SHA-256 witness for reproducibility
+
+`nvsim` benches at ~4.5 M samples/s on x86_64 (~4500× the Cortex-A53 target). It is WASM-ready by construction (no `std::time/fs/env/process/thread`).
+
+### 7.2 What an NV-diamond mesh node would need to look like
+
+Today's COTS reference is the **Element Six DNV-B1** ($8–15k, ~300 pT/√Hz, 1 kHz BW). For a heartbeat-mesh role, a useful node would need:
+
+| Spec | DNV-B1 today | What you'd need for cardiac at 1 m | What you'd need for cardiac at 10 m |
+|---|---|---|---|
+| Sensitivity | 300 pT/√Hz | <1 pT/√Hz (1 s integration) | <1 fT/√Hz (impossible today) |
+| Bandwidth | 1 kHz | 100 Hz sufficient | 100 Hz sufficient |
+| Cost | $8–15k | <$1k for mesh deployment | irrelevant if sensitivity infeasible |
+| Form factor | credit card | mesh-friendly (palm size) | drone-friendly |
+| Gradiometric? | No (single sensor) | **Yes** (3-axis gradiometer needed for ambient rejection) | yes |
+
+The 1 m case is plausible **with** a 2–4 sensor gradiometric array and a magnetically-shielded test enclosure. The 10 m case requires roughly six orders of magnitude more sensitivity than any published NV ensemble has demonstrated. Press-release "miles" requires twelve.
+
+### 7.3 What `nvsim` is for
+
+The simulator's role is **system-design honesty**. Before anyone builds a physical NV node for RuView, you should be able to drop the sensor model into the multistatic fusion graph and answer:
+
+- "If my NV node has 100 pT/√Hz sensitivity, what's the joint posterior P(human alive at (x,y)) given my CSI + 60 GHz + NV evidence at 0.5 m, 2 m, 5 m?"
+- "What sensitivity does my NV node need to add useful information beyond the 60 GHz radar at 2 m?"
+- "What does my published witness change if I swap the NV sensor's contrast from 0.03 to 0.10?"
+
+This is the kind of pre-build sanity check that distinguishes serious open-source quantum-sensing work from press-release physics.
+
+---
+
+## 8. Multi-modal fusion (the real "AI" in the public claims)
+
+The "AI strips environmental noise to isolate cardiac signal" line in the news is doing a lot of work. The honest version is:
+
+1. **Each sensor has a known noise floor** (CSI: ~10⁻² amplitude; 60 GHz: ~µm phase; NV: ~pT). The fusion stage knows this.
+2. **Each sensor has a known geometric precision** (CSI: ~5 m localisation in 30 m mesh; 60 GHz: ~10 cm in 3 m FOV; NV: ~5 cm at 1 m close-confirm).
+3. **Bayesian fusion** combines them with priors (room geometry, human anatomy, expected HR/BR ranges).
+4. **AI** lives in the *learned* parts: AETHER re-ID embeddings, MERIDIAN domain-generalisation, gesture DTW templates, intention pre-movement nets. Not in "magic noise stripping."
+
+RuView's `ruvector::viewpoint::attention::CrossViewpointAttention` is the fusion primitive: a softmax over per-sensor evidence weighted by a geometric-bias matrix `G_bias` (Cramer-Rao Fisher information). The fusion is **physics-aware**: a sensor with low Fisher information for the target's location automatically gets low attention weight.
+
+This is **not** the press's "AI does magic." It's standard sensor-fusion theory. The novelty in RuView is not the fusion — it's the fact that all the layers (CSI / 60 GHz / NV-simulator) live in one Rust workspace with a coherent type system and a single fusion crate.
+
+### 8.1 Concrete fusion data flow
+
+```rust
+// Pseudocode showing the multistatic fusion graph
+let csi_evidence    = csi_pipeline.run(csi_frames)?;          // ~10 Hz, 30 m range
+let radar_evidence  = mr60bha2_pipeline.run(radar_frames)?;   // ~50 Hz, 3 m range
+let nv_evidence     = nvsim_pipeline.run(simulated_nv)?;       // ~10 kHz, 1 m range (sim)
+
+let geometric_bias  = GeometricBias::from_node_layout(&nodes);
+let fused_persons   = MultistaticArray::fuse(
+    &[csi_evidence, radar_evidence, nv_evidence],
+    &geometric_bias,
+    &PriorRoomGeometry::load(&room_id)?,
+)?;
+
+// Each fused person carries: (x, y, z, HR_bpm, BR_brpm, vector_pose, person_id_embedding,
+//                              p_alive, p_human, novelty_flag, witness_hash)
+```
+
+This is **already** the architecture in `ruvector::viewpoint::fusion::MultistaticArray`. The NV row is currently fed by `nvsim` (simulator) instead of a hardware sensor. Everything else is shipping.
+
+---
+
+## 9. Privacy, ethics, legal — the part the press skipped
+
+A heartbeat-detecting mesh is dual-use. It can find a heart-attack victim trapped in rubble (the original Mass Casualty Assessment Tool / `wifi-densepose-mat` use case, ADR-014) **or** it can surveil people in their homes. RuView's project line is unambiguous on this:
+
+1. **Civilian, opt-in deployments only.** Search-and-rescue, elder-care, building occupancy for HVAC, hospital ICU vitals. Not surveillance.
+2. **No directional pursuit.** RuView does not ship beam-steering, target-following, or remote person-of-interest tracking primitives. The mesh is designed for fixed-area observation with consent.
+3. **Data minimisation.** The fused output is `(presence, HR, BR, pose, p_alive)` — not raw CSI / radar / NV streams. Raw streams are processed at the edge and discarded after fusion.
+4. **PII detection on the wire.** ADR-040 (PII gates) blocks identifying biometric streams from leaving the local mesh without explicit user authorisation.
+5. **Adversarial-signal detection.** `ruvsense::adversarial` flags physically-impossible signal patterns that would arise from a malicious node trying to inject false detections — protection against mesh attacks.
+6. **No export-controlled hardware.** RuView targets <$50 COTS components. ITAR / EAR-listed sub-THz coherent radars and shielded NV ensembles are explicitly out of scope.
+
+The Ghost Murmur press story exists in a different ethical universe — covert military intelligence ops with no consent, no notice, and no opt-out. **RuView is not that.** This spec is the open-source version: same physics, opposite governance.
+
+### 9.1 Legal boundaries (US, non-exhaustive)
+
+- **18 USC §2511** (federal wiretap) — RF sensing of presence and vital signs is generally not a "wire/oral communication" intercept, but state-law recording statutes can apply if audio is involved.
+- **HIPAA** — vital-sign data from medical contexts requires HIPAA-covered handling.
+- **FCC Part 15** — ESP32 and 60 GHz radar emissions must remain compliant (RuView firmware defaults to compliant power).
+- **ITAR / EAR** — high-power coherent sub-THz radar, shielded NV ensembles, and certain ML models trained on pose data may be export-controlled. RuView avoids this category.
+- **State biometric laws (BIPA, CCPA, similar)** — pose / gait / cardiac signatures may qualify as biometric identifiers; consent regimes vary.
+
+If you are deploying RuView outside a controlled research setting, talk to a lawyer who actually does this for a living.
+
+---
+
+## 10. How to actually implement, on RuView, today
+
+This section is the build guide. It assumes you're starting from a clean RuView checkout and want a working 3-node CSI mesh + 1 mmWave node + a simulated NV row, fused into a single `(x, y, HR, BR, p_alive)` stream.
+
+### 10.1 Hardware bill of materials
+
+| Tier | Component | Qty | Per-unit | Total |
+|---|---|---|---|---|
+| 1 | ESP32-S3 8 MB DevKit | 3 | $9 | $27 |
+| 1 | Mini-PoE injector + cat6 | 3 | $6 | $18 |
+| 2 | ESP32-C6 + Seeed MR60BHA2 | 1 | $15 | $15 |
+| 3 | (NV node — simulated only) | 0 | — | — |
+| Edge | Raspberry Pi 5 (8 GB) or Mini PC | 1 | $80 | $80 |
+| Network | unmanaged GbE switch | 1 | $25 | $25 |
+| **Total** | | | | **$165** |
+
+NV-diamond hardware is intentionally absent: it stays as `nvsim` output until COTS NV boards drop below $1k.
+
+### 10.2 Firmware build + flash
+
+Use the procedure in `CLAUDE.local.md` (Python subprocess wrapper, ESP-IDF v5.4 on Windows; native bash on Linux). The relevant binaries are:
+
+```bash
+# CSI node firmware (ESP32-S3, 8 MB)
+firmware/esp32-csi-node/build/esp32-csi-node.bin
+
+# Vitals node firmware (ESP32-C6 + MR60BHA2, ADR-021)
+# See `wifi-densepose-vitals` crate for ESP32-C6 builds
+```
+
+Provision each CSI node with target IP and channel:
+
+```bash
+python firmware/esp32-csi-node/provision.py \
+  --port COM7 \
+  --ssid "RuViewMesh" \
+  --password "your-mesh-key" \
+  --target-ip 192.168.50.20 \
+  --channel 6
+```
+
+Repeat with `--target-ip 192.168.50.21`, `.22` for the other two nodes.
+
+### 10.3 Edge software stack
+
+On the Pi or mini-PC:
+
+```bash
+git clone https://github.com/ruvnet/RuView.git
+cd RuView/v2
+cargo build --release \
+  --bin wifi-densepose \
+  --bin wifi-densepose-sensing-server \
+  --no-default-features
+```
+
+This produces `wifi-densepose` (CLI) and `wifi-densepose-sensing-server` (Axum web UI) without the optional `eigenvalue` BLAS feature, so no vcpkg/openblas dependency.
+
+### 10.4 Configure the mesh
+
+Drop a `mesh.toml` next to the binary:
+
+```toml

+
+### 10.5 Running with a simulated NV row
+
+To pretend you have an NV magnetometer in the fusion graph (for stress-testing the architecture without buying $8k of hardware), enable the `nvsim` row in `mesh.toml`:
+
+```toml
+[fusion]
+nv_sim_weight = 0.5     # any value >0 enables the simulated row
+
+[nv_sim]

+config            = "default"            # PipelineConfig::default()
+```
+
+The fusion stage will treat the simulated row as if it were a real sensor with known noise model. Drop the `nv_sim_weight` to `0.0` to remove it. This is exactly the architecture you want for sober quantum-sensing system design.
+
+### 10.6 Web UI
+
+```bash
+./wifi-densepose-sensing-server --config mesh.toml --listen 0.0.0.0:8080
+```
+
+Open `http://<pi-ip>:8080`. You get:
+
+- live 2D occupancy plot per node and fused
+- HR / BR per detected person
+- pose skeleton (17 keypoints, AETHER re-ID)
+- multistatic Fisher-information overlay
+- Cramer-Rao precision ellipse per detection
+- privacy-mode controls (record/erase/quarantine)
+
+This is the closest open-source approximation to "the operator console for a Ghost Murmur node" that anyone can actually deploy in their living room with $165 of hardware.
+
+### 10.7 Honest performance you can expect on this build
+
+| Metric | Expected (3-node CSI + 1 mmW + nvsim row) |
+|---|---|
+| Person detection (LOS) | 95% TPR, 5% FPR at 0–15 m |
+| Person detection (through 1 wall) | 85% TPR, 8% FPR at 0–10 m |
+| HR accuracy (LOS, 0–3 m) | ±2 bpm |
+| HR accuracy (through 1 wall) | not reliable on this hardware |
+| BR accuracy (any mode, 0–10 m) | ±1 br/min |
+| Pose keypoint error (LOS) | ~10 cm at 0–5 m |
+| Latency (sensor → fused output) | 80–150 ms |
+
+**This is not 40 miles.** It's a small house. That's the entire point of this spec.
+
+---
+
+## 11. Open research questions
+
+Things that would *materially* push this stack closer to a credible "Ghost Murmur" capability — and which RuView is open to PRs on:
+
+1. **Sub-$1k NV-ensemble board**. Rumored development at QDM Tech, NVision, Adamas Nanotechnologies; nothing shipping yet.
+2. **Active stand-off cardiac radar at 76–81 GHz** with FCC-compliant power. Possible but $$ for the chipset.
+3. **Distributed coherent processing** across CSI nodes (true multistatic phase-coherent SAR). Requires sub-ns clock sync (PTP or GPS-disciplined).
+4. **RaBitQ binary-sketch novelty gate on ESP32** (ADR-086). Pushes the compute load down to the node so the mesh scales to hundreds of cells.
+5. **Adversarial-signal detection at the firmware tier**. Currently in the Rust signal crate; should be partially pushed to ESP32 firmware so a compromised node can't poison the mesh.
+6. **Privacy-preserving fusion**. Differential privacy on the fused output stream; same theory as DP-SQL but for sensor fusion.
+7. **Validated `nvsim` against published MCG measurements**. The simulator is internally consistent; we have not yet asserted byte-equivalence with a published cardiac-magnetic field measurement.
+
+---
+
+## 12. Comparison: RuView vs. Ghost Murmur (as reported)
+
+| Dimension | RuView heartbeat mesh (this spec) | Press-claimed Ghost Murmur |
+|---|---|---|
+| Range | 0.5–30 m | tens of miles |
+| Modalities | WiFi CSI + 60 GHz radar + NV simulator | NV-diamond magnetometry only (per press) |
+| Cost per node | $9–15 | unstated, presumably $$$$$ |
+| Through-wall | yes (CSI) | unstated |
+| Vital signs (HR + BR) | yes | claimed: HR |
+| Open source | yes (Apache-2.0 / MIT) | classified |
+| Independent verification | yes (SHA-256 witnesses, ADR-028) | no |
+| Plausible per published physics | yes | not at the claimed ranges |
+| Ethics governance | civilian opt-in only | covert military |
+| Build today on $200 | yes | no |
+
+**The honest framing**: RuView is not Ghost Murmur. Ghost Murmur (as reported) is not Ghost Murmur either — the physics doesn't support it. Both names point at the same family of capabilities. RuView is the one you can actually build in your garage.

+# Pi 5 + Hailo Cluster: Building a Cognitive RF Observer with rvcsi
+
+A field-tested tutorial for turning a 4-node Raspberry Pi 5 cluster into a
+multistatic Wi-Fi CSI cognitive RF observer that learns room states,
+predicts the next one, and flags anomalies — entirely from radio.
+
+**Estimated time:** 4–6 hours (hardware 1h, firmware 1h, software 1h, calibration 1–3h)
+
+**What you will build:** A self-learning 4-node cluster that captures Wi-Fi
+Channel State Information from a stable RF beacon, encodes each frame into a
+128-dimensional fingerprint on an on-device Hailo-8 NPU, clusters those
+fingerprints into discrete room states with stable IDs across runs, models
+state transitions with a 2nd-order Markov chain (with measurable predictive
+skill above chance), and persists everything to a queryable brain corpus on
+a workstation. The whole thing runs over Tailscale and is operated through
+a single CLI with **34 subcommands**.
+
+**Who this is for:** RF engineers, smart-home hackers, security researchers,
+and ML/embedded folks comfortable with Linux + systemd. No specific signal-
+processing background required — but you do need patience for hardware
+quirks (nexmon_csi cross-compile is a known dead end; see step 3).
+
+> **The TL;DR**: 4× Pi 5 + 2× Hailo-8 → CSI → 128-d embeddings → cosine
+> k-means with warm-start → 2nd-order Markov → SQLite brain → 34-subcommand
+> operator CLI. Production-grade signal: 39% top-1 ceiling on next-state
+> prediction (16× chance baseline), continuous fleet/drift/anomaly
+> monitoring, and a 12-category time-series corpus.
+
+> **About the name "rvcsi" in this tutorial.** When this tutorial was
+> first written, the cluster's per-Pi capture services were named with
+> an `rvcsi` prefix (`cog-rvcsi-stream`, `cog-rvcsi-correlator`) as
+> branding only — the actual code was Python and didn't depend on the
+> upstream [`ruvnet/rvcsi`](https://github.com/ruvnet/rvcsi) Rust
+> runtime. **As of 2026-05-13**, the v0-appliance project has accepted
+> [ADR-207](https://github.com/ruvnet/v0-appliance/blob/main/docs/adr/ADR-207-rvcsi-library-integration.md)
+> (rvCSI library integration — Option D) and shipped a Rust binary
+> `cog-rvcsi-pi` built on rvcsi-runtime 0.3 that replaces the three
+> Python services. The cutover is per-Pi, operator-driven, with
+> one-command rollback (`scripts/rvcsi-pi/install-rvcsi-pi.sh` and
+> `uninstall-rvcsi-pi.sh`). A given cluster may be running either
+> stack while migration is in progress; the schema and operator
+> surface are unchanged across the cutover. See ADR-207's
+> Implementation log for the current state.

+### Hardware
+
+| Item | Quantity | Approx. cost | Notes |
+|------|----------|--------------|-------|
+| Raspberry Pi 5 (8GB) | 4 | ~$80 each | 4GB works but tight under sustained load |
+| Hailo-8 M.2 HAT (AI Kit) | 2 | ~$110 each | Only 2 needed — encoder is split across cluster-1 + cluster-2 |
+| MicroSD (64GB, A2) | 4 | ~$10 each | A2 class strongly recommended for sustained writes |
+| USB-C PD power supply (27W) | 4 | ~$12 each | Pi 5 draws 5A at full Hailo load |
+| Active cooler | 4 | ~$5 each | Cluster-2 sustains thermal load — passive will throttle |
+| Workstation (≥16GB RAM, Linux) | 1 | — | Hosts the brain HTTP service + clusterer + anomaly daemon |
+| Stable Wi-Fi beacon | 1 | — | Any AP on the same 5 GHz channel. We use ch.149/80MHz. Stability matters more than identity. |
+
+**Total parts cost:** ~$580 plus workstation.
+
+> **Important:** All 4 Pi 5s must use the on-board `bcm43455c0` radio. USB
+> Wi-Fi adapters with otherwise-similar chipsets **will not** work — nexmon's
+> firmware patches are silicon-specific. See ADR-206 § "USB Wi-Fi dongle
+> rabbit-hole" for the painful version of that lesson.
+
+### Software prerequisites
+
+| Component | Version | Notes |
+|-----------|---------|-------|
+| Pi OS Bookworm (Lite) | 64-bit, kernel 6.6+ | Use the Lite image — Desktop slows boot and burns SD writes |

+
+**Why this split?** Multistatic fusion (combining CSI from 4 spatial vantage
+points into a single weighted observation) is computationally cheap but
+benefits from being on **one** node so the other three only do capture +
+encode. Hailo-8 is the bottleneck cost, so we put two on the cluster
+(one for redundancy, one for the fusion node) and let `cluster-3` + `v0`
+run as pure capture sensors.

+
+## 3. Per-node firmware: nexmon_csi on Pi 5
+
+**Critical lesson learned (saved you a week):** the workstation x86_64
+cross-compile path for nexmon_csi on Pi 5 **does not work**. The 39-hunk
+patch series applies cleanly on a native Pi 5 ARM build, and fails in
+subtle ways elsewhere.
+
+The recipe that works:
+
+```bash
+# On each Pi 5 (not the workstation):
+sudo apt update && sudo apt install -y \
+    raspberrypi-kernel-headers bc bison flex libssl-dev make \
+    gcc gawk qpdf cmake build-essential libpcap-dev clang gcc-arm-none-eabi
+
+git clone https://github.com/seemoo-lab/nexmon.git ~/nexmon
+cd ~/nexmon
+source setup_env.sh
+make
+
+cd patches
+git clone https://github.com/seemoo-lab/nexmon_csi.git
+cd nexmon_csi
+
+# Apply the Pi-5-friendly patch series — all 39 hunks should apply clean
+# on native ARM. If you see "Hunk #N FAILED", you are almost certainly
+# cross-compiling from x86_64. Stop. Build on the Pi.
+./install.sh
+
+# Switch on:
+sudo mcp                       # 'monitor capability provisioning' — enable
+sudo nexutil -Iwlan0 -s500 -b -l34 -v<86-char base64 capture filter>
+```
+
+> **Pi 5 kernel gotcha:** Pi OS Bookworm ships two kernels — `kernel8.img`
+> (4K pages) and `kernel_2712.img` (16K pages, Pi 5 only). nexmon_csi
+> currently builds clean against `kernel8.img`. Add `kernel=kernel8.img`
+> to `/boot/firmware/config.txt` if you've switched. **After the switch,
+> SSH by hostname via Tailscale** — host keys + DHCP gotchas otherwise.
+
+> **Clock-skew first-boot trap:** Pi 5 has no RTC. First-boot apt will
+> reject "future-dated" `Release` files. Patch your firstboot to wait for
+> `systemd-timesyncd` before running `apt-get`.
+
+The complete commands + full troubleshooting matrix is in the
+[detailed gist](https://gist.github.com/ruvnet/88e7b053c41cb4f4af7a7ec4af873017) — section "Firmware: nexmon_csi on Pi 5".
+
+---
+
+## 4. Per-node services
+
+Each cluster Pi runs a small fixed set of systemd services. Per-host
+topology:
+
+| Service | cluster-1 | cluster-2 | cluster-3 | v0 |
+|---|:--:|:--:|:--:|:--:|
+| `cog-csi-emitter` (raw CSI capture from nexmon) | ✓ | ✓ | ✓ | ✓ |
+| `cog-csi-adapter` (Rust binary; CSI → 256-byte float frames) | ✓ | ✓ | ✓ | ✓ |
+| `cog-rvcsi-stream` (publishes frames to rvcsi-correlator) | ✓ | ✓ | ✓ | ✓ |
+| `cog-hailo-encoder` (frames → 128-d fingerprints on Hailo-8) | ✓ | ✓ | — | — |
+| `cog-rvcsi-correlator` (multistatic fusion across 4 nodes) | — | ✓ | — | — |
+| **Expected service count** | **4** | **5** | **3** | **3** |
+
+The topology is encoded in the workstation's `cog-query fleet-status`
+subcommand, which compares per-host expected services against live
+`systemctl is-active` results. A flat-service check would falsely flag
+cluster-3 and v0 as degraded (they have neither Hailo nor the correlator
+— that's by design).
+
+> **rvcsi cutover (ADR-207 Option D, 2026-05-13).** The three services
+> `cog-csi-emitter`, `cog-csi-adapter`, and `cog-rvcsi-stream` are
+> being consolidated into one Rust binary `cog-rvcsi-pi` built on
+> [rvcsi-runtime](https://crates.io/crates/rvcsi-runtime). The new
+> binary holds the same per-Pi role and the same expected-service
+> count from the operator's view (`fleet-status` already understands
+> both layouts). Deploy with
+> `bash scripts/rvcsi-pi/install-rvcsi-pi.sh <pi-host>`; revert with
+> `scripts/rvcsi-pi/uninstall-rvcsi-pi.sh`. The cutover is per-Pi,
+> not flag-day — mixed Python/Rust clusters are supported. The Hailo
+> encoder + correlator stay Python in this phase; their Rust ports
+> are tracked as follow-on ADRs.
+
+All unit files + the install script are in the
+[detailed gist](https://gist.github.com/ruvnet/88e7b053c41cb4f4af7a7ec4af873017) — section "Per-node systemd units".
+
+---
+
+## 5. Workstation pipeline
+
+The workstation runs ten user-mode units (3 daemons, 7 timers):
+
+| Unit | Type | Cadence | Purpose |
+|---|---|---|---|
+| `cog-rfmem-tail` | daemon | continuous | Ingests live brain entries into the workstation mirror |
+| `cog-rfmem-recall` | daemon | continuous | kNN-matches current fingerprint vs persisted ones, posts `rfmem-recall` |
+| `cog-rfmem-anomaly` | daemon | continuous | 13-axis anomaly detector, posts `rfmem-anomaly` + `rfmem-state-transition` |
+| `cog-rfmem-indexer` | timer | every 5 min | Updates HNSW index for kNN |
+| `cog-rfmem-compress` | timer | hourly | Compresses old brain entries |
+| `cog-rfmem-daily` | timer | nightly 04:00 | Per-day stats roll-up (`rfmem-daily`) |
+| `cog-rfmem-states` | timer | hourly | Re-runs cosine k-means w/ warm-start (`rfmem-state-summary`) |
+| `cog-rfmem-insights` | timer | nightly 04:55 | NL synthesis, posts `rfmem-insights` |
+| `cog-rfmem-drift-check` | timer | nightly 05:00 | Audits cluster file/unit drift, posts `rfmem-drift` |
+| `cog-rfmem-mirror` | timer | hourly | Mirrors cluster-2 brain → workstation read-replica |
+
+Install in one shot:
+
+```bash
+git clone https://github.com/<your-fork>/v0-appliance.git
+cd v0-appliance
+bash scripts/rfmem/install-workstation.sh
+```
+
+The installer is **idempotent** — rerunning is safe and only enables
+units that aren't yet enabled. It also wires a git post-commit hook
+that auto-deploys + auto-smoke-tests on every commit touching
+`scripts/rfmem/`. That closes the "I edited the repo but forgot to
+deploy" gap that bit us repeatedly in early development.
+

+
+## 6. Calibration: getting from raw CSI to room states
+
+This is the longest step but largely passive — let it run.
+
+### 6.1 Walk the room
+
+For 30–60 minutes after the cluster is live, walk through every room you
+want recognized. Sit, stand, move between rooms, repeat. The encoder is
+learning to map "what the room looks like in CSI" into 128-d vectors;
+diversity here matters more than total time.
+
+### 6.2 First clustering pass
+
+```bash
+# Force-trigger the clusterer (it normally fires hourly):
+systemctl --user start cog-rfmem-states.service
+python3 scripts/rfmem/cog-query.py states
+```
+
+Output looks like:
+
+```
+=== rfmem-states — k=16, n=12,847 ===
+  state #0   π=0.184  dwell=42.3s  centroid_drift=0.012  (default)
+  state #1   π=0.121  dwell=18.1s  centroid_drift=0.003
+  state #4   π=0.087  dwell=29.6s  centroid_drift=0.041
+  ...
+```
+
+**Stable IDs across runs.** The warm-start k-means recipe matches new
+centroids to the prior run's centroids by cosine similarity before
+assigning IDs. This means state #4 stays state #4 between hourly runs —
+otherwise downstream Markov transitions would scramble after every
+re-cluster.
+
+### 6.3 Let the Markov chain build
+
+After a few thousand transitions (a few hours of activity), check:
+
+```bash
+python3 scripts/rfmem/cog-query.py prediction-accuracy
+```
+
+You should see something like:
+
+```
+=== prediction-accuracy — training-set top-1 ceilings ===
+  1st-order:  37.1%  (16x chance baseline of 6.25%)
+  2nd-order:  39.4%  (16x chance baseline of 6.25%, 1.06x gain over 1st)
+```
+
+The 2nd-order chain beats 1st-order because it conditions on the
+**previous** state as well as the current one. Self-loops are excluded
+from the argmax (a transition is by definition a state change).
+
+### 6.4 Verify the room learned itself
+
+```bash
+python3 scripts/rfmem/cog-query.py insights
+```
+
+Reads like:
+
+```
+The cluster has observed 446,231 fingerprints, clustering them into
+16 discrete RF states. The room exhibits moderately diverse (stationary
+entropy 0.82/1.0). State #4 is the dominant 'default' state (π=0.214);
+state #13 is the rarest baseline (π=0.018).
+Prediction skill (last hour, 2nd-order): top-1 12.4% (1.98x chance),
+top-3 31.0% (1.65x chance, 412 transitions) (training-set ceiling
+39.4% — operating @ 31% of capacity).
+```
+
+That "operating @ 31% of capacity" line is the operational efficiency:
+how close live performance is to the model's theoretical ceiling. Big
+gap = the room is being noisy in ways the static cluster model doesn't
+capture. Small gap = you're near SOTA for this static model.
+
+---
+
+## 7. Operating the cluster: the cog-query CLI
+
+A single CLI binary with **34 subcommands** + 4 machine-readable JSON
+modes. Practical ones (full list in the gist):
+
+| Subcommand | What it does |
+|---|---|
+| `summary --hours 1` | Bird's-eye view of last hour: anomalies, transitions, recall hits |
+| `top-events --hours 24 --limit 5` | Highest-info events in window (combines novelty + tier + recency) |
+| `top-events --json` | Same, agent-consumable |
+| `insights` | Natural-language synthesis (paragraph) — what the cluster thinks |
+| `insights --json` | Same, structured |
+| `insights --post` | Same, persisted to brain as `rfmem-insights` |
+| `stats` | Corpus: per-category counts, dimensions, vector counts |
+| `motion` | Recent motion events |
+| `anomalies --sort info` | Anomalies sorted by composite info score (1.0–8.0) |
+| `circadian` | 24-hour bin of activity — does the room have a daily rhythm? |
+| `by-state` | Per-state metrics (dwell, σ-baseline, novelty distribution) |
+| `markov` | Top transitions by frequency, both 1st + 2nd-order |
+| `transitions --sort novelty` | Rare/surprising transitions |
+| `dwell-times` | How long the room stays in each state |
+| `prediction-accuracy` | 1st + 2nd-order top-1 ceilings |
+| `baseline-drift` | Has the noise floor shifted? (slow change) |
+| `centroid-drift` | Has any state's RF signature materially changed? |
+| `fleet-status` | Per-host expected-service liveness check |
+| `fleet-status --json` | Same, agent-consumable |
+| `fleet-status --post` | Same, persisted to brain as `rfmem-fleet` (heartbeat) |
+| `check-drift` | Workstation/cluster file + unit drift audit |
+| `replica-status` | Hourly cluster-2 → workstation mirror health |
+
+### The fleet-health triad
+
+Three subcommands cover the operator's full health picture:
+
+- `check-drift` — file content drift (what's deployed vs what's in git)
+- `replica-status` — workstation mirror lag (last successful sync)
+- `fleet-status` — service liveness across the 4 Pis (topology-aware)
+
+If all three are green, the cluster is healthy. If any one fires, you
+have a concrete starting point.
+
+---
+
+## 8. What you can measure
+
+After a week of runtime, you can answer questions like:
+
+- **"What's the room's most common 'baseline' state?"** → `states` shows
+  the π-dominant cluster ID.
+- **"Did anything weird happen last night?"** → `anomalies --sort info
+  --hours 12` sorts by combined-information score (novelty × tier × state-
+  rarity × calmness).
+- **"How predictable is the room?"** → `insights` reports stationary
+  entropy (0.0 = single state, 1.0 = uniform). Most rooms land 0.6–0.9.
+- **"What's the most novel transition ever observed?"** → `transitions
+  --sort novelty --limit 1`. We've seen transitions with
+  `transition_p=0.0000` — never observed before in 446k+ embeddings.
+- **"Is the room changing slowly?"** → `centroid-drift` flags states
+  whose 128-d signature has moved > 0.05 cosine distance since the prior
+  clusterer run. Common cause: a piece of furniture moved.
+- **"What's the daily rhythm?"** → `circadian` bins activity by hour.
+  Most rooms show clear morning/evening peaks.
+
+---
+
+## 9. Troubleshooting
+
+| Symptom | Likely cause | Fix |
+|---|---|---|
+| `nexmon_csi` build fails with FAILED hunks | Cross-compiling from x86_64 | Build on the Pi natively |
+| Pi 5 stops booting after kernel switch | Wrong `kernel=` in `/boot/firmware/config.txt` | Use `kernel=kernel8.img` |
+| First boot fails on `apt update` | No RTC → clock skew, apt rejects "future-dated" Release files | Wait for `systemd-timesyncd` in firstboot |
+| `cog-rfmem-now` times out | Workstation daemon swap-thrashing | Bump `MemoryMax=` in unit file (we run 1G) |
+| `fleet-status` shows DEGRADED on cluster-3 / v0 | Topology unaware (old version) | Update to latest — per-host expected-services |
+| Cluster-2 Hailo encoder silent | `cp -r` made encoder a directory, not a file | `install -m 0755` instead |
+| 2nd-order Markov top-1 = 0% | Self-loop dominates argmax | Zero out self-loop before `.argmax()` |
+| State IDs change between runs | No warm-start k-means | Update clusterer to match new centroids to prior run by cosine |
+| HardFaults during embedded N6 bring-up | (Different topic, see [ADR-027](../adr/) for STM32N6 startup notes) | — |
+
+---
+
+## 10. Next steps
+
+Once your cluster is producing stable predictions and clean fleet health,
+the natural directions are:
+
+1. **Cross-room correlation** — train a second cluster in another room
+   and feed both into the workstation. The brain already supports
+   multiple namespaces.
+2. **Active sensing** — instead of passively observing whatever beacon is
+   present, drive your own (e.g., dedicated 5 GHz beacon AP at fixed
+   power). Eliminates upstream variability.
+3. **Vital signs** — the RuView project has companion code for extracting
+   heart-rate and breathing from CSI; the 128-d encoder output is a
+   reasonable input feature.
+4. **Federated training** — multiple physical sites publishing to a shared
+   brain. Each site keeps its own clusters; transitions are the shared
+   vocabulary.
+5. **Push to upstream RuView** — if your cluster develops capabilities not
+   in this tutorial (you'll know by the time you've written the README),
+   send a PR.
