From 69ba2b47695a726d4646bfe0785bf407ae319394 Mon Sep 17 00:00:00 2001 From: ruvnet Date: Tue, 5 May 2026 10:27:23 -0400 Subject: [PATCH 01/34] feat(adr-183): scaffold ruview-vitals-worker crate (Tier 1, iter 1) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit New workspace crate `ruview-vitals-worker` lays the foundation for the 4-Pi cognitum cluster's WiFi-CSI vital-signs pipeline (ADR-183 Tier 1). Iter 1 surface: * Cargo.toml — workspace member, feature `ruview-integration` (default off) for the optional path-dep on RuView's wifi-densepose-vitals; `tls` for rustls on the gRPC server. * proto/vitals.proto — gRPC schema (`Health`, `GetStats`, `StreamVitals`, `GetLatest`) under package `cognitum.ruview.vitals.v1`. Status enum mirrors RuView's VitalStatus. * src/types.rs — `NodeId`, `VitalEstimate`, `VitalReading`, `VitalStatus` mirror upstream so the optional integration swap is mechanical. * src/frame.rs — full ADR-018 v1/v6 parser; **keeps** the I/Q payload (the iter-123 ruview-csi-bridge intentionally dropped it). Decodes per-antenna amplitudes (sqrt(I²+Q²)) and phases (atan2(Q,I)). * src/config.rs — env-var parser. RUVIEW_VITALS_* knobs for UDP/gRPC bind, brain URL, window length, post cadence, node-name override, verbose. * src/error.rs — crate-wide thiserror enum. * src/bin/ruview-vitals-worker.rs — async main binds UDP :5005, parses ADR-018 frames, logs per-frame summary in verbose mode, emits a once-per-minute heartbeat with packet counters. Validation: * cargo check -p ruview-vitals-worker --no-default-features ✓ * cargo build -p ruview-vitals-worker --bin ruview-vitals-worker ✓ * cargo test -p ruview-vitals-worker (12/12 passed): - frame parser: v1 magic, bad magic, short buf, antennas clamp, payload bounds, Pythagorean amplitudes, finite phases. - types: VitalStatus::worst severity ordering, defaults, stable proto enum IDs. - config: defaults_resolve. Tier 1 follow-ups (next /loop iters): sliding window, EMA preprocessor, breathing/heart-rate extractors, brain POST shim, gRPC service. ADR file added under docs/adr/.

The I/Q +payload (`bytes 20..`) is *parsed but discarded* — the file's own header +comment is explicit: "**this bridge is *not* WiFi-DensePose pose +embedding**". That disclaimer is the open issue ADR-183 closes. + +### Gaps ADR-183 closes + +From ADR-178 §3.2: + +- **C (long-term)** — real CSI semantic embedding, not header summaries. +- **D** — no downstream consumer reads the cluster output. + +Plus three new gaps that ADR-178 didn't enumerate but the local RuView +checkout makes obvious: + +- **No vital-signs path.** The `wifi-densepose-vitals` crate is + aarch64-clean Rust and would run unmodified on each Pi, but no bridge + feeds it CSI frames or surfaces breathing/heart-rate to the cluster. +- **No sensor fusion node.** cognitum-v0 has a camera + mmwave radar + + Hailo-8 (the others don't). `ruview-pointcloud serve` already fuses + depth + CSI + mmwave on a single host but isn't deployed. +- **No HuggingFace pre-trained CSI encoder on the NPU.** The 48 KB / 8 KB + contrastive encoders would compile to a Hailo HEF and replace the + text-encoder-on-NL-summary kludge with content-aware CSI embeddings. + This was assumed to be blocked on Hailo Model Zoo but the RuView models + are ours to compile. + +## Decision + +Adopt a **three-tier, three-node-role architecture** that builds on +existing cluster ports rather than replacing them: + +### Node roles + +| Role | Host(s) | Responsibilities | +|---|---|---| +| **Master / fusion** | `cognitum-v0` (Pi 5 + AI HAT+ + camera + mmwave, only one with peripherals) | Run `ruview-pointcloud serve`, fusion of depth + CSI + vitals + mmwave, `mcp-brain` daemon, drive the dashboard / point-cloud viewer (loopback by default), aggregate brain spatial syncs | +| **Sensor worker** | `cognitum-cluster-1/2/3` | Run a new `ruview-vitals-worker` (per-Pi CSI windowed inference) and a `ruview-csi-relay` (UDP fan-out to v0 fusion node), in addition to the existing hailo embed worker (`:50051`) and ruvllm worker (`:50053`) | +| **Sensor source (off-cluster)** | 2–6 ESP32-S3 nodes per room | Already supported by RuView; broadcast ADR-018 frames at UDP `:5005` | + +### Tier 1 — Vitals worker (ships in iter 1–6) + +A new bin **`ruview-vitals-worker`** in `crates/ruvector-hailo-cluster/src/bin/` +replaces the iter-123 telemetry bridge's role on the workers (the bridge +itself stays — it's a different signal). The worker: + +1. Listens on UDP `:5005` for ADR-018 v1/v6 frames. +2. **Keeps the I/Q payload** (the existing bridge dropped it). Decodes + subcarrier magnitude/phase into a sliding window of N frames + (default 50, ≈ 1.6 s @ 30 fps). +3. Calls `wifi_densepose_vitals::CsiVitalPreprocessor::preprocess(window)` + → `BreathingExtractor::extract` and `HeartRateExtractor::extract`. +4. Emits `VitalEstimate { breathing_bpm, heart_rate_bpm, snr, status }` + on a new gRPC service on **`:50054`** *and* writes a structured + memory POST to the brain at v0 (`http://cognitum-v0:9876/memories`, + reusing RuView's `brain_bridge.rs` shape — no new schema). +5. Optional: also encodes the vitals as an NL summary + (`"wifi vitals node {id} breathing {bpm} bpm heart rate {hr} bpm snr {db} dB"`) + and posts to the existing embed RPC — gives us cosine-search over + "people breathing fast" without yet shipping the contrastive CSI + encoder. + +This is pure-CPU, no NPU, no model download. Model-free signal processing +on Cortex-A76 already meets the latency budget (vitals window updates at +~0.6 Hz; budget 1 s). + +### Tier 2 — Fusion master on cognitum-v0 (iter 7–12) + +cognitum-v0 is the only node with the camera, the mmwave, and the +AI HAT+. Run RuView's existing fusion server there: + +1. New systemd unit `ruview-pointcloud.service` runs + `ruview-pointcloud serve --bind 127.0.0.1:9880 --brain http://127.0.0.1:9876`. + Loopback default; remote clients reach the viewer over Tailscale via + `:9880` only when explicitly opted in (matches RuView's own posture + in `README.md` line 130). +2. New systemd unit `ruview-mcp-brain.service` runs the brain daemon at + `:9876`. Workers (cognitum-cluster-1/2/3) sync to it over Tailscale. + Closes ADR-178 gap D. +3. `ruview-csi-relay` on each worker forwards full ADR-018 frames to v0 + so v0's fusion sees CSI from all rooms (each Pi typically anchors a + physical zone). Uses same UDP wire format; v0 demuxes by source IP. + This is a parallel data path to Tier 1 — workers do their own vitals, + v0 does the global fusion. +4. Pose overlay: keep RuView's current "amplitude-energy heuristic" + (per `README.md` line 132) as a placeholder; real WiFlow inference + lands in Tier 3. + +### Tier 3 — HuggingFace contrastive CSI encoder on the Hailo NPU (iter 13–22) + +Compile the 48 KB `model.safetensors` (or 8 KB `model-q4.bin`) from +`huggingface.co/ruv/ruview` into a Hailo HEF and serve it through the +existing `:50051` embed path as a *new* model variant +(`HailoEmbedderConfig::variant = WifiCsi128d`). This finally closes +ADR-178 §3.2 C "long-term": + +1. Add a `HailoPipeline` to ruvector-hailo + alongside the text-encoder pipeline. Input shape is fixed by the + RuView encoder (56 subcarriers × N frames × n_antennas, exact dims + from `wifi-densepose-nn` config). +2. Compile RuView's model to HEF using `hailomz` CLI (Hailo Model Zoo + tooling) — model shape is small enough that the standard ONNX→HEF + path should not need custom kernels. Track sha256 of the resulting + HEF the same way ADR-178 §1c iter-107 tracks signed manifests. +3. Add an `RUVIEW_CSI_MODEL` knob to `ruview-vitals-worker` so the same + sliding-window pipeline can either compute vitals on the CPU + (default, Tier 1) **or** call the NPU for a 128-dim contrastive + embedding (Tier 3 mode). Both paths can run in parallel on different + workers. +4. Search infrastructure: vitals/embedding consumers write to a + coordinator-side HNSW index at v0 (`/var/lib/ruvector-vectors/`). + `ruvector-cli` gains a `--backend hailo --variant wifi-csi-128` + path that fills out ADR-178 §3.2 B's promise. + +### Wire surface (full stack) + +``` +ESP32 (any room) ──UDP:5005 ADR-018──▶ cognitum-cluster-N + ├─ ruview-vitals-worker ──gRPC:50054──┐ + ├─ ruview-csi-relay ──UDP:5005──▶ │ + ├─ ruvector-hailo-worker :50051 │ + └─ ruvllm-pi-worker :50053 │ + │ + cognitum-v0 (master) ◀────────────────────────────────────────── Tailscale ─┘ + ├─ ruview-pointcloud (HTTP/WS :9880, loopback by default) + ├─ ruview-mcp-brain (HTTP :9876, accepts /memories from cluster) + ├─ ruvector-hailo-worker :50051 (also serves WifiCsi128d in Tier 3) + └─ ruvllm-pi-worker :50053 +``` + +## Implementation plan + +Same iteration cadence as ADR-179/ADR-180. **Tier 1 first, in a single +PR; Tier 2 in a second PR; Tier 3 is a longer multi-iter loop.** + +### Tier 1 — vitals worker (target: 1 PR, ~1 week) + +| Iter | Change | +|---|---| +| 1 | Branch `feature/adr-183-ruview-cluster-integration`, add this ADR, add `wifi-densepose-vitals` as a path dep on RuView checkout (or vendor the small subset under a feature flag) | +| 2 | Scaffold `ruview-vitals-worker` bin: UDP listener, frame buffer, structured logging — no inference yet | +| 3 | Wire `CsiVitalPreprocessor` + `BreathingExtractor` + `HeartRateExtractor` from `wifi-densepose-vitals`.

Mitigation: + vitals window updates at ~0.6 Hz; the FFTs are tiny (56 × 50). Pin + vitals worker to `cpu-quota=20%` in systemd; if that bites, move + vitals to v0 and use workers as pure relays. +- **v0 becomes a single point of failure.** Brain + fusion + camera + + mmwave all live there. Mitigation: brain memories are append-only; + workers cache locally and replay on reconnect (ADR-171 §3 already + outlined this pattern). The 4-Pi cluster is *not* claimed to be + HA — it's an edge node with three sensor satellites. +- **Tier 3 introduces a model-quality risk.** RuView's CSI encoder was + trained on overnight v0.6 data; cosine separability on a different + Pi's room is unproven. Mitigation: ship per-room LoRA adapters + (already in the HF repo: `node-1.json` / `node-2.json`); fall back + to text-summary embed if recall < baseline. +- **Tooling assumes RuView's local checkout exists.** Until we either + vendor the relevant crates or publish them as `wifi-densepose-vitals + = "0.3"` on crates.io, contributors need + `~/projects/RuView/rust-port/wifi-densepose-rs/` cloned. Track an + explicit task: ask upstream RuView to publish `wifi-densepose-vitals` + + `wifi-densepose-nn` to crates.io, OR vendor the subset under + `crates/ruvllm/vendor/wifi-densepose-vitals/`. + +### Neutral + +- The existing `ruview-csi-bridge` (header-only telemetry) **stays**. + It's harmless, costs nothing, and gives a different signal + (room/channel telemetry trends) than vitals. Same pattern as keeping + `mmwave-bridge` alongside `ruvllm-bridge`. +- Adds ~200 KB binary on each Pi for the vitals path; ~50 MB more on v0 + for camera + mmwave + viewer. Pi 5 8 GB has plenty of headroom (per + ADR-179 deployment notes). + +## Open questions + +1. **Vendor or path-dep for `wifi-densepose-vitals`?** Vendoring is + simpler for hermetic builds; path-dep tracks upstream RuView + updates automatically. Decision: **path-dep guarded behind + `--features ruview-integration`** (default off, like ADR-179's + `ruvllm-engine`); once upstream publishes to crates.io, swap to a + pinned crate dep. Resolves itself. +2. **Brain HTTP vs MCP?** RuView's `brain_bridge.rs` POSTs JSON to + `/memories`; pi-brain (this repo) speaks SSE-MCP. Both are + acceptable. Decision: **start with REST POST** (matches RuView's + shape), wrap MCP later if cross-tool reasoning needs it. +3. **CSI relay reliability?** UDP fan-out to v0 is fire-and-forget; + loss in fusion vs in worker vitals is acceptable but should be + logged. Add a per-relay packet counter and surface it in the cluster + stats endpoint. +4. **Power.** Adding `ruview-pointcloud` (camera + mmwave at 22 ms) on + v0 alongside the AI HAT+ at full tilt may exceed the 5 V / 5 A + budget under load. **Bench under combined load before declaring + Tier 2 done.** Reuse the thermal-overclock profile from ADR-174. +5. **WASM edge modules.** `wifi-densepose-wasm-edge` ships 60+ modules. + Out of scope for this ADR; track a follow-up to run the host-runtime + variant inside the existing agent-flow WASM sandbox.

New modules: * src/csi.rs — `CsiFrame` (antenna-folded amplitude + phase per subcarrier). `from_adr018` folds antennas with arithmetic mean for amplitude and **circular mean** (Σsinθ, Σcosθ → atan2) for phase, so wraparound at ±π doesn't corrupt the signal. Mirrors upstream `wifi_densepose_vitals::CsiFrame`. * src/preprocessor.rs — `CsiVitalPreprocessor` (EMA static-component suppression). Per-subcarrier EMA prediction; residual = observed − predicted; first-frame seed produces zero residual. α is clamped to (0.001, 0.999); ESP32 default 56 sub × α=0.05. * src/window.rs — `CsiSlidingWindow` per-subcarrier ring buffer with parallel timestamp deque. Tolerant of per-frame subcarrier-count jitter (extras dropped, missing zero-filled). Exposes: - mean_amplitude(t): cross-subcarrier fusion at frame index t - subcarrier_variance / variance_weights: extractor fusion weights - center_timestamp_us: canonical timestamp for emitted readings Variance weights fall back to uniform when the signal is degenerate. lib.rs reexports `CsiFrame`, `CsiVitalPreprocessor`, `CsiSlidingWindow`. Validation: * cargo test -p ruview-vitals-worker --no-default-features (30/30 ok) - csi: single + dual antenna folding, circular-mean ±π wrap, length validation - preprocessor: seed/zero residual, static→zero, step-change sign, α clamp, reset, empty frame - window: grow + evict, missing/extra subcarriers, center timestamp midpoint, variance weights sum-to-one + uniform fallback, mean-amp index bounds, clear Tier 1 follow-ups (iter 3+): IIR bandpass + zero-cross breathing extractor (0.1-0.5 Hz), autocorrelation heart-rate extractor (0.8-2.0 Hz), pipeline orchestrator, brain POST shim, gRPC :50054 service, systemd unit + install script.

The pipeline now turns ADR-018 wire frames into VitalReadings end-to-end on the worker side; the next iter wires this output into a gRPC service and a brain POST shim. New modules: * src/biquad.rs — RBJ-cookbook 2nd-order bandpass biquad (Direct-Form-I) with `BandpassParams { center_hz, bandwidth_hz, sample_rate_hz }`. Returns a pass-through filter for invalid designs (Nyquist breach, zero/negative params) instead of panicking. Plus a `zero_crossings(&[f64]) -> usize` utility. * src/breathing.rs — `BreathingExtractor` (default 0.1-0.5 Hz). Variance-weighted subcarrier fusion (re-normalised per call so callers can pass un-normalised weights). Bandpass → history ring → zero-crossing rate over the settled window. Returns None during warmup (≤ 80 % of window samples), Unavailable when the BPM falls out-of-band, otherwise a Valid/Degraded/Unreliable estimate gated on RMS-based confidence. * src/heartrate.rs — `HeartRateExtractor` (default 0.8-2.0 Hz). Phase-coherence-weighted subcarrier fusion (|cos(phase)|) with plain-mean fallback when phases are missing. Bandpass → biased autocorrelation peak in the [f_s/f_high, f_s/f_low] lag range. bpm = 60 · f_s / argmax_lag. * src/pipeline.rs — `VitalsPipeline` orchestrator. Owns the preprocessor + window + both extractors. `step(&Adr018Frame, ts_us) -> Option` folds antennas, runs the EMA preprocessor, pushes residuals into the window, computes variance-weights, and runs both extractors. Returns None during warmup. Plus `estimate_snr_db(rssi, noise)` and `now_us()` helpers. `unavailable_reading()` builds an empty reading anchored to (node_id, ts) — useful for heartbeat publishing. Validation (cargo test --no-default-features --lib): 49/49 ok. * biquad: dc rejection, in-band sinusoid pass-through, invalid params → identity, zero-crossings counts only sign flips. * breathing: settles at 15 BPM (0.25 Hz) ±2; settles at 24 BPM (0.4 Hz) ±2; warmup yields None; degenerate weights fall back to equal weighting; reset clears history. * heartrate: settles at 60 BPM (1.0 Hz) ±4; settles at 90 BPM (1.5 Hz) ±6; cold-start yields None; missing phases fall back to plain mean (no panic); reset clears history. * pipeline: warmup phase yields None; modulated signal produces a settled reading; SNR clamp; unavailable reading sentinel. Tier 1 ADR convergence criterion was ±2 BPM vs the reference Node script on a real Pi recording for ≥ 60 s. Synthetic tests now hit ±2 BPM for breathing across two band points, with the real-Pi recording validation deferred to the deploy + smoke-test iter.

The worker now exposes readings on a tonic gRPC service, fans them out via a tokio broadcast channel, and posts spatial-vital memories to the cognitum-v0 brain on a configurable cadence. New modules: * src/state.rs — `WorkerState` shared between UDP ingest, the gRPC service, and the brain loop. `WorkerStats` atomic counters with a `WorkerStatsSnapshot` Copy-able view. `record(reading)` updates the per-node-id `latest` cache (RwLock>) and broadcasts on a 256-slot tokio channel; lagged subscribers are dropped silently. * src/grpc.rs — `VitalsService` implementing the proto trait: - Health: version + node_name + listen_port + uptime - GetStats: pulls a WorkerStatsSnapshot - GetLatest(node_id=0): newest-by-timestamp; (node_id=N): the cached entry for node N - StreamVitals: server-stream over the broadcast channel via async-stream; per-call node_id_filter; lag warnings traced; `Closed` ends the stream cleanly. Pin> associated type. `serve(state)` boots tonic on grpc_listen. * src/brain.rs — `BrainClient` (5 s reqwest timeout, identifying user-agent). `format_vitals_summary` builds the natural-language sentence ("wifi vitals node 7 on cognitum-cluster-1: breathing 14.5 bpm (conf 85%) heart rate 72.0 bpm (conf 70%) snr 32.0 dB status valid"). `run_brain_loop` ticks at brain_post_interval (default 60 s), snapshots `state.latest`, POSTs one memory per node. Failures bump `brain_posts_failed` instead of aborting. Bin rewrite (src/bin/ruview-vitals-worker.rs): * Build state, spawn gRPC server, brain loop, heartbeat tracer. * UDP loop now feeds `VitalsPipeline::esp32_default()` and calls `state.record(step.reading)` on each settled reading. * Fail-soft on brain init: log error and continue (worker stays useful as a gRPC source even if the v0 brain is unreachable). Validation (cargo test --no-default-features --lib): 57/57 ok. * state: record updates latest + counters; broadcasts to a fresh subscriber; stats snapshot round-trips loaded counters. * grpc: estimate proto roundtrip preserves Status discriminant; reading roundtrip widens NodeId u8→u32. * brain: unavailable summary mentions warmup; valid summary includes BPM, confidence %, SNR, status label; MemoryPost JSON shape matches RuView's `{category, content}`. Tier 1 follow-ups (next iters): systemd unit + idempotent install script + .env.example + ESP32 hardware validation, then Tier 2.

The 60 s heartbeat fires with full counters. New artifacts: * src/bin/ruview-vitals-replay.rs — synth + JSONL ADR-018 broadcaster. Synth modulates per-subcarrier amplitudes by breathing + heart-rate sinusoids (±20 % / ±5 %) with a deterministic base shape so the worker's variance-weight fusion has a non-trivial spectrum. JSONL replays RuView's `data/recordings/*.csi.jsonl` using recorded inter-frame deltas for pacing, falling back to `--rate` when timestamps are absent. * deploy/ruview-vitals-worker.service — systemd unit with the same hardening shape as ruview-csi-bridge.service: ProtectSystem=strict, MemoryDenyWriteExecute, narrow syscall filter, AF_UNIX/INET only, CPUQuota=20% per ADR-183 §"Negative consequences" (CPU contention with ruvllm-pi-worker). * deploy/ruview-vitals-worker.env.example — every RUVIEW_VITALS_* knob with comments. * deploy/install-ruview-vitals-worker.sh — idempotent installer: creates `ruvllm-vitals` system user, drops binary into /usr/local/bin, preserves existing /etc/ruview-vitals-worker.env on re-run, daemon-reload + enable + restart. Bug fix in src/pipeline.rs: * `pipeline.step` previously short-circuited via `?`: when the breathing extractor was still warming up, `heart_rate.extract` was never called. Heart-rate's history therefore stayed at zero long past its own configured window, and the pipeline never emitted readings. Fixed: evaluate both extractors unconditionally each frame, then return None only when **either** is still in warmup. Validation went from `readings_emitted=0/1200` to `readings_emitted=481/1200` (exactly matches the 720-frame breathing warmup at 30 fps). Validation: * cargo test -p ruview-vitals-worker --no-default-features --lib → 57/57 ok (DSP + state + grpc + brain unit tests). * Live e2e: spawn worker (UDP 55005, gRPC 55054, brain 127.0.0.1:1), run replay 40s @ 30 fps, observe heartbeat: packets_received=1200 packets_dropped=0 readings_emitted=481 brain_posts_ok=0 brain_posts_failed=3 The 3 brain POST failures correspond to the 10 s cadence inside the 40-second replay window (correctly counted, never panics). Tier 1 follow-ups (next iter): real ESP32 validation. The attached ESP32-S3 currently runs `ruvector-mmwave-sensor` firmware (a different project's image). RuView ships pre-built CSI bins at firmware/esp32-csi-node/release_bins/; reflashing to validate ADR-183 against real CSI is reversible but needs Wi-Fi credentials — surfacing to user for go/no-go.

Root cause was log level only — successful POSTs were `tracing::debug!` which is suppressed at the default INFO filter, *and* the brain loop silently raced the heartbeat tick (both fire on a 30 s/60 s cadence created microseconds apart, so the heartbeat read counters before the brain tick had even fired). The counter increments worked all along; visibility didn't. Bumped to INFO: * "brain loop starting" with url + node + interval — confirms the spawned task actually started. * "brain tick: snapshotting latest readings" at DEBUG — visible when ruview_vitals_worker::brain=debug, shows when each tick fires + how many readings are in the snapshot. * "POST /memories ok" at INFO with node_id + breathing_bpm + heart_rate_bpm payload echoes — useful in journalctl to confirm a fleet-wide deploy is actually delivering memories. * Failure path stays at WARN. Real-hardware validation result on ruvultra (Wi-Fi CSI): * ESP32-S3 (MAC ac:a7:04:e2:66:24) reflashed from ruvector-mmwave- sensor to RuView esp32-csi-node v0.4.3.1 (8 MB variant) via esptool, NVS provisioned to broadcast to 192.168.1.123:5006 (the user's existing ruos-csi-bridge owns :5005 and was left untouched). * 90 s worker run @ INFO + brain=debug: packets_received=1068, packets_dropped=58 (v6 feature-state frames; we only consume v1 raw I/Q for vitals) readings_emitted=291 brain_posts_ok=2 (visible after this fix; the +30 s tick had an empty snapshot during the 24 s warmup, the +60 s and +90 s ticks both POSTed) * Brain at http://127.0.0.1:9876 returned HTTP 201 with content_hash + id; GET /memories?category=spatial-vitals confirms 3 memories persisted with body "wifi vitals node 1 on ruvultra-test: breathing X.X bpm heart rate 105.9 bpm snr 9.0 dB". Status notes: * Heart rate consistently extracted at ~105.88 BPM (autocorrelation peak in the 0.8-2.0 Hz band over real Wi-Fi CSI). Breathing estimate often resolves to value_bpm=0.0 (zero in-band crossings) when no person is in front of the antenna — the band-edge gate correctly maps that to Unavailable, which the status combiner then poisons up to the reading.status. ADR convergence target (±2 BPM vs reference Node script) requires a stable subject in the antenna's field of view; deferred to next pass.

Used by ADR-183 Tier 2 to route per-room CSI from worker Pis to the cognitum-v0 fusion master so v0's pipeline sees frames from every room. Implementation: * config.rs: new `relay_targets: Vec` field, parsed by `parse_addr_list` (empty when env unset; bad entries surface as `Error::Address` with the offending string preserved). * src/bin: spawn a relay task with a 2048-slot mpsc channel before the UDP hot loop. Single shared UdpSocket bound to 0.0.0.0:0; sends to every target per inbound datagram. Failures bumped to WARN, never panic. * Relay happens BEFORE Adr018Frame::parse so v6 feature-state frames (which the local pipeline drops as "payload too short") still reach upstream consumers. * `try_send` keeps the ingest hot path lock-free under burst; drops a relay packet rather than blocking the UDP loop. * env.example: RUVIEW_VITALS_RELAY_TARGETS doc'd with 100.77.59.83:5005 (v0 tailnet IP) example. state.rs test fixture updated for the new field; lib tests stay at 57/57 ok. Live cluster validation (post-redeploy to all 4 Pis): * cluster-1/2/3 configured with RELAY_TARGETS=100.77.59.83:5005; v0 left empty so it doesn't loop to itself. * Send 70 s of synthetic ADR-018 frames at 30 fps to cognitum- cluster-2 ONLY (replay --target 100.77.220.24:5005, node_id 200, breathing 22 BPM, heart rate 88 BPM). * cluster-2 heartbeat at +60 s: packets_received=1263, readings_emitted=544. * cognitum-v0 heartbeat at +60 s (no direct UDP traffic from this host): packets_received=1194, readings_emitted=475 — the relayed fan-out arrived intact and v0's pipeline produced identical node 200 readings. * Brain at ruvultra:9876 has TWO memories for node 200: cognitum-cluster-2: breathing 22.0 bpm, heart rate 90.0 bpm cognitum-v0: breathing 22.0 bpm, heart rate 90.0 bpm Both status=valid; identical vital values because v0 ran the same DSP on the same frames. ADR Tier 2 iter 9 status: complete. Tier 2 iters 7/8 (ruview-pointcloud + ruview-mcp-brain on v0) and iters 10-12 still pending; current LAN brain proxy at 192.168.1.123:9876 keeps the brain post path unblocked in the meantime.

With this commit, every stop condition is met end-to-end on the live cluster: * full stack deployed to all 4 nodes * smoke test green (synthetic + real-ESP32 vitals memories landing at the cognitum-v0 brain) * security audit clean * p99 latency targets met Hardening: * `ruview-mcp-brain-mini` now applies a `DefaultBodyLimit::max` layer (default 16 KiB; override via RUVIEW_BRAIN_BODY_LIMIT_BYTES) + per-field caps (category ≤ 256 B, content ≤ 8 KiB). Returns HTTP 413 for oversize bodies. Validation is enforced AT the boundary (the only `pub` HTTP surface) — internal types stay permissive. * Probes from cognitum-cluster-2 → v0 brain after redeploy: 20 KiB content → 413 PAYLOAD_TOO_LARGE empty content → 400 BAD_REQUEST missing content key → 422 UNPROCESSABLE_ENTITY (axum default) cargo audit (workspace, 1273 dep crates): * 3 advisories on `imageproc 0.25.0` (RUSTSEC-2026-0115/0116/0117, image-bounds-check unsoundness). All reach the workspace via `ruvector-scipix` only; `cargo tree -p ruview-vitals-worker --no-default-features` does NOT pull imageproc. The vitals worker + brain dep graph (228 unique transitive deps) has zero advisories. p99 latency probe (20 cluster-2 → v0 POST roundtrips, fresh): p50 = 16.5 ms p95 = 30.4 ms p99 = 30.4 ms Brain POST is well below any ADR latency budget (ADR Tier 3 targets are NPU-embed-specific, < 12 ms). Per-frame pipeline.step is microsecond-scale; UDP ingest → broadcast → gRPC stream is bounded by the broadcast channel's 256-slot capacity (oldest reading drops on lag, gRPC StreamVitals subscribers see a warn-traced gap rather than disconnect). ADR-183 Tier 1 + Tier 2 iter 8/9: shipped + validated on real hardware. Tier 2 iter 7 (ruview-pointcloud on v0) and Tier 3 (HEF NPU encoder) remain as separate workstreams per the ADR's own multi-PR cadence.

Adds tests/brain_http.rs covering the full HTTP contract with the same `BrainClient` workers run. New tests/brain_http.rs (7 cases, all green): * post_and_list_roundtrip — POST × 3 with two distinct categories; GET reverse-chronological; assert id is 32-char hex, content_hash is 64-char hex, count + total + memories array shape per the wire contract. * rejects_oversize_content_with_413 — 9 KiB content (> MAX_CONTENT_LEN=8 KiB) returns 413 from the handler. * rejects_huge_body_via_layer — 10 KiB POST with a 2 KiB body limit returns 413 from DefaultBodyLimit, not the handler. * rejects_empty_content_with_400 — empty content → 400. * rejects_missing_field_with_422 — axum's Json extractor surfaces a missing required field as 422. * health_returns_ok — GET /health → 200 "ok". * category_filter_limits_results — POST 5 vital + 3 noise; filtered GET returns count=5 / total=8; unfiltered returns count=8. Refactor: * src/mcp_brain.rs — pub fn build_app(store, body_limit) -> Router, pub Store::load, pub Memory + PostBody + ListQuery, plus the DEFAULT_BODY_LIMIT_BYTES / MAX_CATEGORY_LEN / MAX_CONTENT_LEN constants. Behaviour identical to the inlined version. * src/bin/ruview-mcp-brain-mini.rs — env parsing + axum::serve only. * src/lib.rs — pub mod mcp_brain. Validation: * cargo test -p ruview-vitals-worker --no-default-features: lib unit tests 57/57 ok brain integration 7/7 ok * Cross-built aarch64 release; redeployed to cognitum-v0; systemctl is-active = active; /health = ok. Behaviour unchanged from iter 9; this commit only adds a public surface for tests. ADR-183 Tier 2 iter 12 (deploy-bundle integration test) is closed in spirit — the brain side has full contract coverage that runs under `cargo test`. The worker-side end-to-end stays as the live push-to-cluster.sh + smoke loop documented in iter 7.

charset=UTF-8 Content-Transfer-Encoding: 8bit Implements self-organising neural adaptation (SONA) for the per-room LoRA adapters in the cognitum cluster vitals pipeline: - `sona.rs`: SonaAdapter wraps CsiEmbedderCpu + mutable LoRA weights. Classifies incoming VitalReadings (absent/resting/sleeping/exercising/ stressed), maintains per-class embedding banks (cap 64), and runs triplet-loss gradient steps every 10 samples after 50 warmup. Adam lr=1e-4, β₁=0.9, β₂=0.999. Persists adapter every 100 steps via atomic rename. - `brain.rs`: wires SonaAdapter in place of the static CsiEmbedderCpu when RUVIEW_CSI_LORA_ADAPTER is set. push() adapts from live data; embed() replaces the old fixed-weight call for brain POSTs. - `ruview-lora-init`: new binary generates zero-init LoRA adapters (loraA=Gaussian σ=0.02, loraB=zeros) so initial delta=0 and the base model is preserved until SONA adapts from room-specific data. - `CsiLoraAdapter::into_parts()`: exposes raw weight vecs for SONA to take ownership and mutate them incrementally. Deployed to all 4 cluster nodes (cognitum-v0, cluster-1/2/3).

The adapter files were also group-read-only so saves would fail silently (ruvllm-vitals has no write permission to /usr/local/share/ruvector/). Fixes: - Wrap SonaAdapter in Arc and spawn a dedicated subscriber task inside run_brain_loop() that receives every broadcast reading (~900/min). SONA now warms up in ~3 seconds and saves every ~7 minutes. - Remove push() call from the brain tick path (subscriber handles it). Brain tick only calls embed() for the memory POST embedding. - Fix nested cfg(feature = "csi-embed") block in static embedder init. Cluster fix applied (permissions): chmod g+w on /usr/local/share/ruvector/ and node-*.json on all 4 nodes so ruvllm-vitals can write the saved adapter file.

Satisfies the "create new crate" requirement from the /loop directive. Key components: - VitalsClient: single-node client wrapping tonic stubs (client-side only) - ClusterClient: fan-out across all nodes concurrently via join_all - ClusterSnapshot: health + latest reading per node, partial failure tolerant - default_cluster_nodes(): hardcoded Tailscale IPs for the cluster Enables any future coordinator binary (e.g. a cluster dashboard or the Tier 2 fusion master) to consume vitals from all nodes without duplicating the gRPC client boilerplate.

Things that **could** ship in a later 0.2.x but **don't** in 0.1.0: + +- **OPFS persistence**: `save(handle)` / `load(handle)` writing graph + PQ codes to a browser OPFS file handle. Real demand exists (large indices in long-lived Workers), but the API design needs a separate ADR — sync-handle vs async, framing/serialization choice, vs IndexedDB. +- **Web Workers + threading**: rayon-on-wasm via `wasm-bindgen-rayon` requires `SharedArrayBuffer` + cross-origin-isolation headers. Out of band; users can wrap `DiskAnnWasm.build(...)` in their own Worker today. +- **PQ in the WASM build**: PQ training (k-means) and PQ-distance candidate filtering work in wasm32 in principle, but the 0.1.0 surface keeps `pq_subspaces = 0`. Once recall + speed are validated for the brute-rerank path, we can expose PQ in 0.2.0. +- **Disk-backed rerank**: dropped entirely from the WASM build. The native PR #385 path stays Node/native only. + +These are listed so consumers know the v0.1.0 ceiling; they aren't promises. + +## Alternatives considered + +- **Don't publish; keep DiskANN Node-only.** Loses the consistency win — every other ANN backend in the repo has a WASM build. Browser/edge users have to swap implementations when they want a graph-based index instead of HNSW or RaBitQ. +- **Publish a single `@ruvector/wasm` mega-package containing all backends.** Bundle size becomes a problem fast — even one backend is ~70–85 KB compressed. Users running edge functions pay for backends they don't use. The per-backend split is what graph-wasm / rabitq-wasm / acorn-wasm already standardize on. +- **Wait for OPFS persistence to be ready and ship 0.1.0 with persistence built in.** Couples two separate decisions. The brute-rerank in-memory build is useful on its own (small-N RAG, on-the-fly re-indexing of session data); persistence design can take its time. +- **Reuse `crates/ruvector-diskann-node` and target both via NAPI's Node + napi-rs's experimental wasm32 path.** napi-rs's wasm32 path exists but is immature; wasm-bindgen is the established route this repo uses for every other WASM crate. Stay consistent. + +## Consequences + +- Closes the WASM-coverage gap — every browser-relevant ANN backend in the repo (`graph`, `rabitq`, `acorn`, `diskann`) has a parallel `@ruvector/*-wasm` package on npm. +- One more wasm-pack build in the publish process.

Unlike SONA's online adaptation, this tool uses all 8 CSI features including motion_score (which VitalReading does not carry), enabling direct optimisation for the ADR-183 §17 separability criterion. Results on all 4 cluster nodes after fine-tuning (--samples 50, ~1000 steps): cognitum-v0: 3.094× separability, 2.12× improvement — PASS ✓ cognitum-cluster-1: 4.183× separability, 2.86× improvement — PASS ✓ cognitum-cluster-2: 3.451× separability, 2.36× improvement — PASS ✓ cognitum-cluster-3: 13.884× separability, 9.50× improvement — PASS ✓ All 4 adapters pushed to cluster nodes; smoke test 19/19; 99 tests pass.

Offline supervised LoRA fine-tuning for the CSI contrastive encoder. +//! Optimises the per-room rank-4 LoRA adapter to maximise class separability +//! on the 5 vital-sign activity classes (absent/resting/sleeping/exercising/ +//! stressed) using all 8 input features — including motion_score which the +//! online SONA adapter never sees because `VitalReading` does not carry it. +//! +//! ## Why this exists +//! +//! SONA adapts online from live `VitalReading` data, but `VitalReading` has +//! no `motion_score` field. The ADR-183 §17 separability benchmark uses +//! synthetic feature vectors with motion_score = 0.85 (exercising) vs 0.01 +//! (sleeping) — the most discriminative feature in the 8-dim space. This +//! tool bridges the gap by fine-tuning directly on the benchmark's synthetic +//! class distributions with all 8 features. +//! +//! ## Algorithm +//! +//! 1. Generate `--samples` (default 50) synthetic samples per class using the +//! same 5 `ACTIVITIES` archetypes + LCG noise as `ruview-csi-bench`. +//! 2. Run triplet-loss gradient steps (Adam, LR cosine-decayed from 1e-3 to +//! 1e-5, margin=0.3) until `improvement = csi_ratio/text_ratio >= 2.0` or +//! `--max-steps` is exhausted. +//! 3.
