feat(cli): --min-frames override for low-traffic / debug environments

Adds a `--min-frames N` flag to `wifi-densepose calibrate` that overrides
the ADR-135 tier minimum (default 600 frames at 20 Hz for HT20).

Motivation: validated end-to-end against a live ESP32-S3 on COM9, freshly
re-provisioned with target-ip = 192.168.1.50 (this host). The firmware
emits CSI at roughly 0.5 Hz in the current quiet RF environment (most
UDP packets are 0xC511_0006 status, not 0xC511_0001 CSI). Waiting 20 min
to collect 600 frames at install time is operator-hostile; raising the
firmware's CSI rate is a separate concern.

When `--min-frames > 0`, the CLI prints a WARN line stating the override
relaxes the phase-concentration guarantee and should not be used in
production. ADR-135 defaults are preserved unchanged.

Live-hardware validation with `--min-frames 10` over 32 s captured 10
real CSI frames from the ESP32, finalised a baseline-real.bin (860 B)
with correct magic 0xCA1B_0001, version 1, tier HT20, and 52 active
subcarriers. End-to-end pipeline confirmed against real hardware, not
just synthetic UDP.

+
+| Field | Value |
+|-------|-------|
+| **Status** | Proposed |
+| **Date** | 2026-05-25 |
+| **Deciders** | ruv |
+| **Codename** | **HOMECORE-ASSIST** |
+| **Relates to** | [ADR-126](ADR-126-ruview-native-ha-port-master.md) (HOMECORE master), [ADR-127](ADR-127-homecore-state-machine-rust.md) (HOMECORE-CORE), [ADR-130](ADR-130-homecore-rest-websocket-api.md) (HOMECORE-API), [ADR-124](ADR-124-rvagent-mcp-ruvector-npm-integration.md) (SENSE-BRIDGE) |
+| **Tracking issue** | TBD |
+| **Crate** | `v2/crates/homecore-assist` |
+
+---
+
+## 1. Context
+
+Home Assistant's Assist pipeline (`homeassistant/components/assist_pipeline/`) provides
+voice-to-intent-to-response processing. It chains:
+
+1. **STT** (speech-to-text) — Whisper, cloud, or satellite
+2. **NLU** (natural language understanding) — intent recognition via regex/slots
+3. **Intent handler** — maps intent to a HA service call
+4. **TTS** (text-to-speech) — synthesises the response for the caller
+
+HA's intent model (`homeassistant/helpers/intent.py`) is keyword/regex based. Every
+intent is a named template with slot definitions and a handler that dispatches to HA
+services. The built-in intents (`homeassistant/components/conversation/default_agent.py`)
+cover `HassTurnOn`, `HassTurnOff`, `HassLightSet`, `HassNevermind`, `HassCancelAll`,
+`HassGetState`, `HassGetWeather`, and many others.
+
+HOMECORE needs a wire-compatible Assist pipeline so that:
+- The HA iOS/Android companion app's "Assist" button works against HOMECORE.
+- The HOMECORE-API WebSocket `assist` command (ADR-130 §2.2) has a handler.
+- The ruflo agent toolchain (ADR-124) can provide LLM-grade intent disambiguation as a
+  drop-in upgrade path for the P1 regex recognizer.
+
+### 1.1 Ruflo integration approach
+
+Ruflo's agent runner exposes an MCP-over-stdio interface (`node ruflo-agent.js`).
+HOMECORE-ASSIST manages a long-lived subprocess (Q3 Windows concern below), sends
+utterance JSON, and receives intent JSON back. In P1 we ship only the trait surface
+and a `NoopRunner` stub; the real subprocess management is P2.
+
+### 1.2 Ruvector semantic intent matching (P2)
+
+`ruvector-core` provides embedding + cosine-similarity primitives. P2 will add a
+`SemanticIntentRecognizer` that embeds the utterance and compares it to a HNSW index
+of intent exemplars, falling back to the P1 regex recognizer when similarity < 0.75.
+This is the mechanism that allows "dim the lights" to match `HassLightSet` without an
+explicit regex entry.
+
+---
+
+## 2. Design
+
+### 2.1 Module layout (`v2/crates/homecore-assist/`)
+
+| Module | Contents |
+|--------|----------|
+| `intent` | `IntentName` newtype, `Intent` (name + slots), `IntentResponse` (speech + optional card + optional data) |
+| `recognizer` | `IntentRecognizer` trait; `RegexIntentRecognizer` (P1); `SemanticIntentRecognizer` stub (P2) |
+| `handler` | `IntentHandler` trait; built-in handlers: `HassTurnOn`, `HassTurnOff`, `HassLightSet`, `HassNevermind`, `HassCancelAll` |
+| `runner` | `RufloRunner` trait + `RufloRunnerOpts`; `NoopRunner` (P1 stub); real subprocess runner (P2) |
+| `pipeline` | `AssistPipeline`: wires recognizer → handler → response; exposes `async fn process(utterance, language) -> IntentResponse` |
+
+### 2.2 Built-in intent handlers (P1)
+
+| Handler | HA service call | Slot |
+|---------|-----------------|------|
+| `HassTurnOn` | `homeassistant.turn_on` / `light.turn_on` / `switch.turn_on` | `entity_id` |
+| `HassTurnOff` | `homeassistant.turn_off` / `light.turn_off` / `switch.turn_off` | `entity_id` |
+| `HassLightSet` | `light.turn_on` | `entity_id`, `brightness` (0–255), `color_name` |
+| `HassNevermind` | — (no-op, returns acknowledgement) | — |
+| `HassCancelAll` | — (fires `homeassistant_stop_all_scripts` domain event) | — |
+
+### 2.3 IntentResponse
+
+```rust
+pub struct IntentResponse {
+    pub speech: String,
+    pub card: Option<Card>,
+    pub data: Option<serde_json::Value>,
+}
+
+pub struct Card {
+    pub title: String,
+    pub content: String,
+}
+```
+
+### 2.4 RufloRunner trait
+
+```rust
+#[async_trait]
+pub trait RufloRunner: Send + Sync + 'static {
+    async fn spawn(&mut self, opts: RufloRunnerOpts) -> Result<(), AssistError>;
+    async fn send_request(&self, payload: serde_json::Value) -> Result<RufloResponse, AssistError>;
+    async fn shutdown(&mut self) -> Result<(), AssistError>;
+}
+```
+
+`RufloResponse` is `{ intent: Option<Intent>, speech: Option<String> }`.
+
+### 2.5 Pipeline
+
+```rust
+pub struct AssistPipeline<R, H> {
+    recognizer: R,
+    handler: H,
+    runner: Option<Box<dyn RufloRunner>>,
+}
+
+impl<R: IntentRecognizer, H: IntentHandler> AssistPipeline<R, H> {
+    pub async fn process(&self, utterance: &str, language: &str, hc: &HomeCore)
+        -> Result<IntentResponse, AssistError>;
+}
+```
+
+---
+
+## 3. Questions & Answers
+
+### Q1 — Why not reuse HA's existing `homeassistant.helpers.intent` via PyO3?
+
+PyO3 bridges add a GIL lock on every cross-language call; the Assist pipeline processes
+hundreds of short utterances per day from voice satellites. A native Rust recognizer is
+simpler and faster. Python HA can still connect as an external integration via MQTT or
+the HOMECORE WebSocket API.
+
+### Q2 — How does `RegexIntentRecognizer` handle ambiguity?
+
+Patterns are tried in registration order; the first match wins. Slot extraction uses
+named capture groups. A future P2 upgrade can run all patterns, score them by slot
+completeness, and return the highest-scoring match.
+
+### Q3 — Windows subprocess teardown (ruflo runner subprocess on Windows)
+
+`tokio::process::Child` on Windows does not automatically kill the child process when
+the `Child` struct is dropped — `SIGTERM` is not a Windows concept, and `TerminateProcess`
+is not called automatically. Options for P2:
+
+1. Call `child.start_kill()` in a `Drop` impl (requires a `Runtime` handle — tricky in sync Drop).
+2. Wrap `Child` in an `Arc<Mutex<Option<Child>>>` and call `kill()` in an `async fn shutdown()`.
+3. Use a Windows job object to bind the subprocess lifetime to the parent process.
+
+**P2 decision**: implement option 2 (explicit `async shutdown()`) + register a `tokio::signal`
+handler for `Ctrl+C` / `SIGINT` that calls `shutdown()` before exit. Document the Windows caveat
+in the crate README and in `runner.rs`. Job object approach (option 3) is deferred to P3 only
+if option 2 proves insufficient in fleet testing.
+
+### Q4 — Why is `SemanticIntentRecognizer` a P2 stub?
+
+The ruvector HNSW index requires the vector store to be populated at startup with intent
+exemplars. That startup path requires deciding on a serialization format (HNSW index files
+vs. an in-memory array at compile time), which intersects with ADR-084 (RabitQ) and ADR-067
+(ruvector v2.0.5). P2 will define the exemplar format and populate the index.
+
+---
+
+## 4. Consequences
+
+- **Positive**: HOMECORE-API `assist` WebSocket command gets a functional backend.
+- **Positive**: Ruflo LLM pipelines can upgrade intent matching by swapping the `RufloRunner` impl.
+- **Positive**: P1 ships with zero new heavy dependencies (no subprocess spawning, no ML runtime).
+- **Negative**: Regex matching has limited coverage; long-tail utterances will return "I'm not sure".
+- **Deferral**: ruvector semantic recognizer and real subprocess runner both land in P2.

+
+## 1. Context
+
+### 1.1 The Gap
+
+Searching for `CIR`, `channel_impulse`, and `ifft` across the entire Rust workspace (`v2/crates/**`) and Python source (`archive/v1/src/**`) finds zero production code that computes a per-link Channel Impulse Response from CSI. The only `IFFT` call in production is in `wifi-densepose-mat/src/ml/vital_signs_classifier.rs:386`, which applies a bandpass `fft → freq_mask → ifft` to a 1-D vital-sign time series — unrelated to channel sounding.
+
+This is a concrete absence in a codebase that already documents CIR extensively. Four research documents propose CIR as the next major signal-processing tier:
+
+- `docs/research/sota-surveys/ruview-multistatic-fidelity-sota-2026.md` — bandwidth → multipath separability table; explicit `Δτ = 1/BW` formula; states "at 20 MHz the entire room collapses into a single CIR cluster."
+- `docs/research/architecture/ruvsense-multistatic-fidelity-architecture.md` — proposes `ruvector-solver::NeumannSolver` for sparse CIR recovery (Section 2.1); uses `link_gates[i].is_coherent(cir)` in pseudocode (line 583); shows CIR as Stage 2 in the pipeline diagram (Section 4.1).
+- `docs/research/rf-topological-sensing/02-csi-edge-weight-computation.md` — gives `h_ij(τ,t) = IFFT{H_ij(f_k,t)}`, lists RMS delay spread, tap count, and dominant-tap ratio as edge-weight features, and describes ESPRIT for multipath decomposition.
+- ADR-042 — calls for complex-valued CIR in the coherent diffraction tomography path.
+
+Three relevant ADRs are Proposed but unimplemented: ADR-029 (RuvSense multistatic, where `reconstruct_cir()` is referenced in pseudocode but never written), ADR-030 (persistent field model, where CIR baseline subtraction is central), ADR-042 (CHCI, where coherent phase is the primary input).
+
+### 1.2 Hardware Tiers in Scope
+
+| Tier | Device | Bandwidth | Usable subcarriers | Native CIR resolution | Min path separation | Ranging |
+|------|--------|-----------|--------------------|-----------------------|---------------------|---------|
+| A-HE | ESP32-C6, HE-LTF (802.11ax HE-SU/MU/TB) | 20 MHz | ~242 | 50 ns | 15 m | No |
+| A | ESP32-S3, HT20 | 20 MHz | 56 | 50 ns | 15 m | No |
+| B | ESP32-S3, HT40 | 40 MHz | 114 | 25 ns | 7.5 m | Yes |
+| C | Nexmon BCM43455c0 (Pi 5/4/3B+) via rvCSI | 80 MHz | ≥256 | 12.5 ns | 3.75 m | Yes |
+
+Sub-Nyquist sparse recovery (see Section 2) can push native resolution by approximately 3× for sufficiently sparse channels. The ADR-029 research document explicitly targets HT40 (Tier B) as the primary deployment mode for RuvSense.
+
+**Preferred deployment ordering:** Tier A-HE (ESP32-C6 as STA against an 11ax AP) is the preferred Tier A target — 4.7× more active subcarriers than S3 HT20 at identical bandwidth yields a statistically stronger ISTA solve and higher `dominant_tap_ratio` stability under noise, without any additional hardware cost. Tier A (S3 HT20) is the fallback when no 11ax AP is present. Tier B (S3 HT40) is selected when sub-room ranging is required. Tier C (Nexmon Pi install) is used when maximum resolution is needed and a dedicated Pi sensing node is deployed.
+
+Tier A-HE and Tier A share identical native CIR resolution (50 ns / 15 m path separation) and are both non-ranging. Tier A-HE's advantage is **statistical, not numerical**: because Φ is a normalised DFT submatrix with G = 3K, the condition number κ(Φ) ≈ 1 identically across all tiers (σ² ≈ 3 uniformly — see §2.3 for the derivation). The real gain is measurement SNR: 4.7× more independent frequency observations average down noise by √(242/52) ≈ **2.16×**, producing fewer ghost taps and tighter dominant-tap peaks under realistic ESP32 noise levels.
+
+### 1.3 Why CIR Now
+
+The multistatic coherence gate in `ruvsense/multistatic.rs` currently operates on frequency-domain amplitude and phase vectors. The pseudocode in the architecture document calls `link_gates[i].is_coherent(cir)` — passing a CIR, not a raw CSI frame. Without CIR, the coherence gate cannot distinguish a direct-path tap fade from a reflected-path arrival. Without CIR, `ruvsense/tomography.rs` cannot isolate the direct-path component for ranging, and `wifi-densepose-mat/src/localization/triangulation.rs` cannot perform time-of-arrival triangulation. This ADR closes that gap with a single, well-bounded implementation decision.
+
+---
+
+## 2. Decision
+
+### 2.1 Chosen Algorithm: ISTA with a DFT Dictionary (L1-Regularized Sparse CIR Recovery)
+
+The primary CIR estimator is **ISTA** (Iterative Shrinkage-Thresholding Algorithm) with an L1 penalty and a delay-domain DFT dictionary, implemented by wrapping the existing `ruvector-solver::NeumannSolver`. This is not zero-padded IFFT. It is compressed sensing recovery that super-resolves the delay domain beyond the Nyquist limit.
+
+The problem: given the measured frequency-domain CSI vector `H ∈ ℂ^K` (K = 56 or 114 or 256 subcarriers), find the sparse delay-domain representation `x ∈ ℂ^G` (G > K, a finer delay grid) such that:
+
+```
+minimise  ‖H - Φx‖₂²  +  λ‖x‖₁
+```
+
+where `Φ ∈ ℂ^{K×G}` is a sub-DFT dictionary matrix with columns `φ_g = [1, e^{-j2πΔf·τ_g}, …, e^{-j2π(K-1)Δf·τ_g}]^T`, and `τ_g` are the delay-grid points spaced at `1/(G·Δf)`. For ESP32-S3 HT20 with K=56, Δf=312.5 kHz, and G=168 (3× oversampling), the effective delay resolution improves from 50 ns to 17 ns (path separation ~5 m), without any additional hardware.
+
+ISTA is already the algorithmic pattern used in `ruvsense/tomography.rs` for voxel-space reconstruction. The `ruvector_solver::NeumannSolver` is already wired into the workspace and used in `fresnel.rs:280` and `train/subcarrier.rs:225`. There is no new dependency.
+
+### 2.2 Why Not the Alternatives
+
+The table below is the decision record, not a menu of supported options.
+
+| Algorithm | Verdict | Key reason rejected |
+|-----------|---------|---------------------|
+| **Zero-padded IFFT** | Rejected | Sidelobe leakage of -13 dB contaminates adjacent taps; no super-resolution; unacceptable for ranging in rooms where taps are 5-15 m apart. CIRSense (arXiv:2510.11374) independently confirms this by showing standard IFFT requires ≥160 MHz for reliable tap separation in indoor rooms — our ESP32 hardware cannot provide that bandwidth. |
+| **ISTA / L1 (this ADR)** | **Chosen** | Directly reuses `NeumannSolver`; matches pattern in `tomography.rs`; well-understood convergence in 20-50 iterations at K=56; λ is the single tunable hyperparameter; super-resolves by 3× over Nyquist; no eigendecomposition cost. |
+| **OMP / CoSaMP** | Rejected | Greedy order matters when taps are correlated (specular + body reflection within one Nyquist bin). OMP commits to a tap permanently on each iteration; early wrong choices degrade the remaining solution irreversibly. ISTA's continuous shrinkage avoids this. ISTA and OMP yield similar results at high SNR; at low SNR (NLOS links, distant nodes) ISTA is measurably better per Chronos (NSDI 2016) and the pulse-shape paper (arXiv:2306.15320). |
+| **MUSIC / Root-MUSIC / ESPRIT** | Rejected | Requires building a spatial-smoothed covariance matrix `R = (1/(K-L+1)) Σ h_i h_i^H` and then full eigendecomposition. On the aggregator this is O(L³) per link per frame. With 12 links at 20 Hz, this is 240 eigendecompositions/s of 20×20 Hermitian matrices — feasible, but not worth the complexity when ISTA achieves comparable resolution at far lower cost. MUSIC also requires knowing the number of paths P in advance; ISTA does not. MUSIC is superior for angle-of-arrival estimation (its original purpose in SpotFi) but not for the delay-domain CIR that this ADR targets. |
+| **SAGE / CLEAN** | Rejected | Iterative deconvolution methods that require a point-spread function model. CLEAN (radio astronomy origin) works well when the PSF is known and shift-invariant — neither holds for 56-subcarrier WiFi with hardware-specific IQ imbalance. SAGE is theoretically optimal but the E-step requires per-path complex amplitude updates, making implementation significantly more complex than ISTA for comparable output quality at our SNR regimes. |
+| **Neural/deep CIR** | Rejected | No trained model, no paired CIR ground truth in this codebase, and the neural approach requires offline training data that matches each deployment's multipath structure. The 2024-2025 literature on neural CIR (arXiv:2601.06467 "Neuro-Wideband" paper) requires extrapolation across ≥200 MHz — not applicable to 20 MHz ESP32 inputs. Add after a training dataset is collected; not as the initial implementation. |
+| **Treat ESP32-C6 HE-LTF as identical to ESP32-S3 HT20 for CIR purposes** | Rejected | Ignores the 4.7× subcarrier count difference (242 vs 52 K_active). Note that κ(Φ) ≈ 1 identically across tiers (Φ is a normalised DFT submatrix; σ² = G/K = 3 uniformly), so the gain is not numerical conditioning — it is statistical: 4.7× more independent frequency observations suppress noise by 2.16×, producing fewer ghost taps and higher `dominant_tap_ratio` stability. This is a free accuracy improvement that requires only correct pilot masking (a separate `HE20_PILOT_INDICES` constant) and a per-tier `CirConfig`. Treating the C6 as a slow S3 silently discards the largest available accuracy improvement without any hardware change. |
+
+### 2.3 Per-Bandwidth Strategy
+
+There is one algorithm for all tiers, parameterised by bandwidth. The question of whether CIR is worth computing at all is answered by the SOTA survey: "at 20 MHz the entire room collapses into a single CIR cluster." This is not a reason to skip CIR at 20 MHz — it is a reason to be precise about what CIR at 20 MHz provides.
+
+| Tier | K_active subcarriers | G delay bins (3×) | Effective delay res. | Path sep. | Recommended λ | Iterations |
+|------|---------------------|--------------------|---------------------|-----------|----------------|------------|
+| A-HE (HE20, ESP32-C6) | 242 | 726 | ~17 ns | ~5 m | 0.03 | 32 |
+| A (HT20, ESP32-S3) | 52 | 168 | ~17 ns | ~5 m | 0.05 | 30 |
+| B (HT40, ESP32-S3) | 108 | 342 | ~9 ns | ~2.7 m | 0.03 | 35 |
+| C (HT80, Nexmon) | 242 | 768 | ~4 ns | ~1.2 m | 0.02 | 40 |
+
+Tier A-HE uses 802.11ax HE-LTF subcarrier spacing (78.125 kHz in HE-SU 20 MHz) and 802.11ax pilot pattern (8 pilot subcarriers per 802.11ax spec, distinct from the HT20 pilot pattern at ±7, ±21). The resulting K_active matches Tier C in count (242 vs ≥242) but spans only 20 MHz — same native resolution, substantially better statistical SNR from measurement averaging. Tier A-HE is the preferred substrate for ADR-029 RuvSense nodes whenever a compatible AP is present. ADR-110 (Accepted, v0.7.0-esp32) is the firmware substrate that delivers HE-LTF PPDU classification (`csi_collector.c`, frame bytes 18–19), TWT wake slots (`c6_twt.c`), and 802.15.4 epoch timestamps (`c6_timesync_get_epoch_us()`).
+
+**Sensing matrix condition number — κ(Φ) ≈ 1 by construction:** Φ is a normalised DFT submatrix with columns `φ_g = e^{-j2πΔf·τ_g}·(1/√K)` and G = 3K. When active subcarrier indices are uniformly distributed (as they are for all standard 802.11 tier configurations), Φ Φ^H ≈ (G/K)·I = 3·I. Empirical power iteration (100 iterations, both extremes) confirms σ²_max ≈ σ²_min ≈ 3.000 and κ(Φ) = σ_max/σ_min ≈ **1.00 across all tiers** (HT20, HT40, HE20, HE40). The condition number does not improve with K. The Tier A-HE benefit is therefore purely statistical: 4.7× more independent frequency observations suppress noise by √(K_HE/K_HT) = √(242/52) ≈ **2.16×**, not via a better-conditioned linear system.
+
+Minimum viable bandwidth for useful CIR: **both Tier A-HE and Tier A (20 MHz) are useful** for presence-based features (tap count, RMS delay spread, dominant-tap ratio) and for coherence gating. Neither is useful for sub-room ranging (>5 m path separation floor). Tier B (40 MHz) opens direct-path triangulation at room scale. The SOTA survey states this explicitly in the bandwidth-separability table.
+
+The ADR does not gate CIR on bandwidth — it gates downstream consumers. The coherence gate in `multistatic.rs` works at any tier. The ToF triangulation path in `triangulation.rs` is gated behind a minimum bandwidth check (`if cir.bandwidth_hz < 40e6 { return None }`).
+
+#### 2.3a Soft-AP HE Caveat
+
+IDF v5.4 soft-AP does **not** advertise HE capabilities. When the ESP32-C6 is configured as a soft-AP, connecting stations negotiate at 802.11bgn rates and the C6 receives HT-LTF frames, not HE-LTF. The 242-subcarrier HE-LTF sensing matrix is only available when the **C6 operates as a STA associated to an external 802.11ax (Wi-Fi 6) AP**.
+
+This constraint is explicitly noted in `firmware/esp32-csi-node/main/c6_softap_he.c:163`:
+
+```c
+// IDF v5.4 soft-AP does not advertise HE; STAs associate at 11bgn.
+// HE-LTF CSI (242 subcarriers) requires STA mode against an 11ax AP.
+// See: https://github.com/espressif/esp-idf/issues/XXXXX
+```
+
+The same constraint applies to iTWT validation (WITNESS-LOG-110 §A0.6): TWT setup also requires STA mode. Operators deploying ESP32-C6 nodes expecting Tier A-HE SNR benefit must ensure an 11ax AP is in range. If no 11ax AP is available, the firmware falls back to HT20 association (Tier A); the `CirEstimator` detects this from frame byte 18–19 PPDU type (provided by ADR-110's `csi_collector.c`) and selects the appropriate `CirConfig` automatically.
+
+#### 2.3b Measured Performance (2026-05-28, release build, 1× shared `CirEstimator`)
+
+All figures are Criterion median latency on an x86 aggregator (single-threaded). The `CirEstimator` instance is shared across all links in the multi-link scenario (one `Send + Sync` shared reference).
+
+**Latency per `estimate()` call:**
+
+| Config | K_active | G | Single estimate | 12-link sequential | Amortised per-link | Constructor |
+|--------|----------|---|-----------------|--------------------|--------------------|-------------|
+| HT20 (Tier A) | 52 | 156 | 2.72 ms | 17.69 ms | ~1.47 ms | 422 µs |
+| HT40 (Tier B) | 114 | 342 | 13.43 ms | 74.35 ms | ~6.20 ms | 2.03 ms |
+| HE20 (Tier A-HE) | 242 | 726 | 3.20 ms | — | est. ~3 ms | — |
+| HE40 (future) | 484 | 1452 | 9.71 ms | — | est. ~6 ms | — |
+
+Notable: **HE20 (3.20 ms) is faster than HT40 (13.43 ms)** despite 2.1× higher K. This is because ISTA convergence is iteration-count-dominated, and HE20's 4.7× more measurements per iteration tighten the residual faster — HE20 converges in ~32 iters vs HT40's 35+. The naive "more subcarriers = more compute" intuition does not hold when iterations to convergence also decrease.
+
+**Cycle-budget verdict at 20 Hz RuvSense target (50 ms cycle):**
+
+| Scenario | Time used / 50 ms budget | Verdict |
+|----------|--------------------------|---------|
+| HT20, 1 link | 5% | comfortable |
+| HE20, 1 link | 6% | comfortable |
+| HT40, 1 link | 27% | tight |
+| HT20, 12-link multistatic | 35% | OK |
+| **HT40, 12-link multistatic** | **149%** | **exceeds budget** |
+
+HT40 at 12-link multistatic (74 ms / 50 ms cycle) **does not fit the 20 Hz budget** on a single aggregator thread. Mitigation: either (a) parallel-per-link execution across aggregator cores (divides to ~6.2 ms wall-clock at 12 cores), or (b) reduce super-resolution from G = 3K to G = 2K (cuts matrix size by 33%, reducing latency to approximately 9–10 ms sequential). Tier A-HE on C6 fits comfortably even at 12 links sequential (~38 ms, 77% budget) and trivially when parallelised.
+
+**Memory — `Vec<Complex32>` allocation per `CirEstimator::new()`:**
+
+| Config | Φ matrix size |
+|--------|--------------|
+| HT20 (Tier A) | 65 KB |
+| HT40 (Tier B) | 312 KB |
+| HE20 (Tier A-HE) | 1.4 MB |
+| HE40 (future) | 5.6 MB |
+
+Sharing one `CirEstimator` instance across all same-tier links is **mandatory at HE20 and above**. Per-link instantiation at 12 HE20 links would consume 12 × 1.4 MB = 16.8 MB for sensing matrices alone, which is unacceptable on an embedded aggregator. The `Arc<CirEstimator>` pattern (one instance per tier, cloned `Arc` per link thread) is the intended deployment.
+
+### 2.4 Pilot and Null Carrier Handling
+
+ESP32-S3 CSI delivers 64 OFDM tones, of which:
+- 6 are null (DC subcarrier + edge guards, indices ±28 to ±32 in HT20): **set to complex zero** before forming `H`.
+- 4 are pilot subcarriers (indices ±7, ±21 in HT20): **excluded from the L1 optimisation** by masking the corresponding rows in `Φ`. The pilot tones carry known symbols with hardware-added phase noise; including them injects systematic error into the delay estimate. Their indices are available from `CsiFrame.metadata.antenna_config` indirectly, but for ESP32-S3 the pilot indices are standardised per 802.11n HT20 and are hard-coded as constants in the `CirEstimator`.
+
+The resulting effective `K` passed to the solver is 56 − 4 = **52 active data subcarriers** for HT20 (Tier A). For HT40, 114 − 6 = **108 active** (Tier B). For Nexmon HT80, pilots are masked per 802.11n spec (≈14 pilots), leaving ≈242 active (Tier C).
+
+**Tier A-HE (ESP32-C6, HE-LTF):** 802.11ax HE-SU 20 MHz uses a 256-tone FFT with 242 data+pilot subcarriers (±121 around DC), of which **8 are pilot subcarriers** per IEEE 802.11ax-2021 Table 27-47 (HE-SU 20 MHz pilot locations differ from HT20; the 8 pilots are at ±7, ±21, ±43, ±57 in the 0-based 0..255 indexing). After masking 8 pilots, K_active = **242** (not 248; the remaining 6 tones outside ±121 are also null/guard). These pilot indices are distinct from the HT20 constants and are hard-coded as a separate `HE20_PILOT_INDICES` constant in `cir.rs`. The PPDU type field from ADR-110's `csi_collector.c` (frame bytes 18–19) identifies the frame as HE-SU/HE-MU/HE-TB and selects the correct pilot mask at runtime.
+
+This pilot-exclusion step happens inside `CirEstimator::estimate()` before the solver runs. The `Cir` output struct always reports the full `G` delay bins; the caller does not need to know about the masking.
+
+### 2.5 Phase Sanitization Order
+
+**CIR estimation runs after `phase_sanitizer.rs` and after `ruvsense/phase_align.rs`.**
+
+Justification: the ISTA solver minimises `‖H - Φx‖₂²` in the complex domain. If `H` contains hardware-induced phase offsets (SFO, CFO, LO noise), the solver will attempt to fit those offsets as phantom multipath taps at small delays, creating ghost peaks near τ=0. The `PhaseSanitizer` removes 2π discontinuities and z-score outliers. The `phase_align.rs` LO offset estimator removes the inter-packet carrier phase random walk (circular mean of the static-subcarrier phasor). Only after both stages is `H` a clean estimate of the environmental channel transfer function.
+
+The ordering is: raw CSI frame → `phase_sanitizer.rs` → `phase_align.rs` (if multi-antenna or multi-packet) → `CirEstimator::estimate()` → `Cir`.
+
+For single-packet, single-antenna Tier A inputs where `phase_align.rs` is unavailable, the `CirEstimator` applies conjugate multiplication (`H[k] * conj(H_ref[k])`) using the static-environment reference frame stored in `CirEstimator::reference_csi`. This is the same cancellation approach used in `csi_ratio.rs` (ADR-014).
+
+### 2.6 Proposed Rust API

+
+**Design decisions within the API:**
+
+- `Vec<Complex32>` not `ndarray`: The sensing matrix and tap vector are kept as flat `Vec<Complex32>` to avoid pulling `ndarray` into the hot path. The existing `NeumannSolver` in `ruvector_solver` operates on `CsrMatrix<f32>`, which the ISTA wrapper will construct from the real/imag split of `Φ`.
+- **No owned FFT plan**: The 802.11 subcarrier grid is small enough (K ≤ 256) that a reused plan via `rustfft::FftPlanner` provides no measurable benefit over construction per call at 20 Hz update rate.
+- **`Send + Sync`**: The estimator is stateless per `estimate()` call except for `reference_csi`, which is updated only from the control path (single writer). Use a `RwLock<Option<Vec<Complex32>>>` in the actual implementation for multi-threaded aggregators.
+- **Multi-antenna**: Incoherent-average across antennas (magnitudes averaged, not complex). Coherent averaging requires phase-calibrated antennas (ADR-042 CHCI path); this ADR targets the incoherent case available from current ESP32 hardware.
+
+### 2.7 Downstream Consumers
+
+**`ruvsense/multistatic.rs` — coherence gate moves to tap-delay domain**
+
+The existing `CoherenceGate` in `ruvsense/coherence_gate.rs` operates on raw frequency-domain amplitude/phase vectors from `FusedSensingFrame`. Add an overload:
+
+```rust
+impl CoherenceGate {
+    /// Gate using CIR tap magnitudes instead of raw subcarrier amplitudes.
+    /// More robust: tap magnitude changes are isolated to specific delay bins
+    /// rather than spread across all subcarriers.
+    pub fn update_cir(&mut self, cir: &Cir, pose: &Pose) -> GateDecision { /* … */ }
+}
+```
+
+The coherence metric becomes: compare the tap magnitude vector `|taps|` against the running Welford mean/variance of tap magnitudes. A tap that gains or loses power (body entering a delay bin) produces a coherence drop on that specific delay, rather than modulating all 56 subcarriers simultaneously. This reduces false gates from broadband interference.
+
+The `reconstruct_cir()` call site in the `process_cycle()` pseudocode (architecture doc, line 578) is the implementation target:
+
+```rust
+// In multistatic.rs RuvSenseAggregator::process_cycle():
+let cirs: Vec<Cir> = self.link_buffers.iter()
+    .map(|buf| self.cir_estimator.estimate(buf.latest_sanitized_frame()))
+    .collect::<Result<Vec<_>, _>>()?;
+
+let coherent_links: Vec<(usize, &Cir)> = cirs.iter().enumerate()
+    .filter(|(i, cir)| self.link_gates[*i].is_cir_coherent(cir))
+    .collect();
+```
+
+**Tier A-HE additional inputs in `multistatic.rs`** (P1 follow-ups, not blocking this ADR):
+
+- **802.15.4 epoch timestamp**: When the link source is a Tier A-HE ESP32-C6 node (identified by PPDU type from ADR-110), the frame carries a sub-100 µs epoch from `c6_timesync_get_epoch_us()`. In `process_cycle()`, attach this epoch to the `CsiFrame` metadata so that multi-link CIR estimates can be temporally aligned to a shared 802.15.4 reference rather than the aggregator's local clock. This is required for coherent multi-link CIR phase comparison (CHCI path, ADR-042) but is not required for the incoherent coherence gate or `dominant_tap_ratio` features. Mark as `// TODO(ADR-134 P1): attach c6 802.15.4 epoch` in the implementation stub.
+
+- **TWT wake-slot ID for frame independence**: ADR-110's TWT schedule assigns each C6 node a dedicated wake slot (slot ID from `c6_twt.c`). When frames arrive from different TWT slots, the inter-frame CSI phase is independently sampled — the ISTA per-frame independence assumption holds exactly. When a node misses a TWT slot and re-transmits in a later slot, the independence assumption breaks and the `dominant_tap_ratio` estimate for that frame should be down-weighted. Wire `twt_slot_id` from the frame metadata into `CoherenceGate::update_cir()` to detect and down-weight retransmitted frames. Mark as `// TODO(ADR-134 P1): consume twt_slot_id` in the stub.
+
+**Cycle-budget constraint on HT40 multi-link (see §2.3b for measurements)**
+
+Measured latency shows HT40 at 12-link multistatic takes ~74 ms, exceeding the 50 ms cycle budget at 20 Hz. The `RuvSenseAggregator::process_cycle()` implementation must not invoke `CirEstimator::estimate()` for all Tier B links sequentially on the main cycle thread. Required: dispatch CIR estimation across Rayon threadpool workers (`par_iter()` over link buffers) when tier == HT40. Tier A-HE at 12 links sequential (~38 ms) fits within budget and does not require parallelisation, though it benefits from it. Tier A at 12 links sequential (18 ms) has comfortable headroom. Add a `CYCLE_BUDGET_WARNING` log at DEBUG level if a sequential estimate run exceeds 45 ms.
+
+**`wifi-densepose-ruvector/src/viewpoint/coherence.rs` — no change to phase-phasor logic**
+
+The existing `CrossViewpointAttention` in `viewpoint/coherence.rs` computes a differential phasor coherence score in the frequency domain. CIR does not replace this — it augments it. The phase-phasor metric remains the primary edge weight for viewpoint fusion because it is more sensitive to small motions (body within a Fresnel zone). CIR-derived features (tap count, RMS delay spread) become secondary features passed to the attention mechanism as geometric priors, not replacements for phasor coherence.
+
+**`wifi-densepose-mat/src/localization/triangulation.rs` — conditional direct-path ToF**
+
+When `cir.ranging_valid` is true (Tier B or C), the dominant tap's ToF `cir.dominant_tap_tof_s()` is a candidate direct-path range measurement. The triangulation module already imports `ruvector_solver::NeumannSolver` for TDoA solving. Wire in the CIR ToF as an additional observation:
+
+```rust
+// In triangulation.rs, within the TDoA system builder:
+if let Some(tof) = cir.dominant_tap_tof_s() {
+    let range_m = tof * SPEED_OF_LIGHT;
+    // Add as an additional row in the TDoA linear system.
+    // Weight by dominant_tap_ratio (high ratio = reliable LOS measurement).
+    tdoa_builder.add_range(link_id, range_m, cir.dominant_tap_ratio);
+}
+```
+
+This is a conditional enhancement. Tier A (20 MHz) links contribute no ranging; Tier B/C links contribute one ranging measurement each. The existing TDoA solver handles mixed inputs because it is already weighted least-squares via NeumannSolver.
+
+**`wifi-densepose-vitals` — CIR provides marginal improvement only for heartbeat**
+
+For breathing detection (`bvp.rs`, `ruvsense/breathing.rs`): breathing produces a periodic modulation of the direct-path tap magnitude at 0.15–0.5 Hz. Filtering `|cir.taps[dominant_tap_idx]|` through the existing bandpass pipeline is equivalent to doing the same on the peak-subcarrier amplitude — no architectural change needed. The existing Fresnel model (`fresnel.rs`) already models this at the subcarrier level.
+
+For heartbeat detection at 0.8–2.0 Hz: CIR provides a minor SNR benefit by isolating the direct-path tap from multipath interference. This is a marginal improvement in Tier A/B. At Tier C (Nexmon, 80 MHz), isolated direct-path taps become more stable and the heartbeat band SNR improvement is measurable (~2 dB). CIR integration with vitals is therefore: **pass `cir.taps[cir.dominant_tap_idx]` magnitude time series to the existing vital-sign pipeline as an additional input stream**. No new module in `wifi-densepose-vitals` is needed for this ADR; it is a one-line addition to the aggregator's vitals path.
+
+### 2.8 Feature Gating
+
+New Cargo feature: `cir` in `wifi-densepose-signal/Cargo.toml`.
+
+```toml
+[features]
+default = ["cir"]
+
+cir = ["ruvector-solver"]
+```
+
+`ruvector-solver` is already in the workspace (used by `fresnel.rs` and `train/subcarrier.rs`). The feature gate does not add a new dependency — it conditionally compiles `ruvsense/cir.rs`. The feature is **default-on** because:
+
+1. It adds no new crate dependencies.
+2. The `CirEstimator` is zero-cost if never instantiated — the sensing matrix is only allocated on `CirEstimator::new()`.
+3. Downstream consumers (`multistatic.rs`, `triangulation.rs`) will conditionally compile their CIR branches with `#[cfg(feature = "cir")]`.
+
+### 2.9 Test Plan
+
+**Tier 1 — Deterministic synthetic channel (unit test, no hardware)**
+
+Inject a known two-tap channel: direct path at τ₁ = 30 ns with complex amplitude α₁ = 0.8e^{jπ/4}, reflected path at τ₂ = 80 ns with α₂ = 0.3e^{j3π/4}. Compute the expected CSI vector `H[k] = α₁·e^{-j2πk·Δf·τ₁} + α₂·e^{-j2πk·Δf·τ₂}` for K=56, Δf=312.5 kHz. Pass to `CirEstimator::estimate()`. Assert:
+- `cir.active_tap_count` is 2 (with noise_floor = -25 dB relative to α₁ power).
+- `cir.tap_delays_s[cir.dominant_tap_idx]` is within one delay bin of τ₁ = 30 ns.
+- `cir.dominant_tap_ratio` > 0.7 (direct path dominates).
+- The second peak delay is within one delay bin of τ₂ = 80 ns.
+
+This test must be deterministic (no random seed) and must pass under `cargo test --workspace --no-default-features --features cir`. It follows the pattern established by `verify.py` for the Python pipeline.
+
+**Tier 2 — Phase corruption robustness**
+
+Same two-tap channel but add a random per-subcarrier phase ramp (SFO) and a constant phase offset (CFO). Without sanitization: assert the test fails (ghost tap at τ=0 from CFO). With `phase_sanitizer.rs` applied before `estimate()`: assert the same pass conditions as Tier 1. This validates the ordering decision in Section 2.5.
+
+**Tier 3 — Per-bandwidth regression (unit test)**
+
+For K ∈ {56, 114, 256} with the two-tap channel, assert that the dominant-tap delay estimate error is < 1 delay bin, confirming the 3× super-resolution holds across all tiers.
+
+**Tier 4 — Real hardware capture (integration test, COM9)**
+
+Using the existing ESP32-S3 on COM9 (ruvzen), capture 200 CSI frames in a static room (no motion). Assert:
+- `cir.active_tap_count` is consistent across frames (variance < 1 tap count over 200 frames).
+- `cir.dominant_tap_ratio` > 0.5 (LOS dominant path present).
+- `cir.rms_delay_spread_s` is in the range [10 ns, 200 ns] (reasonable for a room).
+
+This test documents expected tap statistics for the ADR-028 witness bundle (see Section 2.10). The test is gated behind `#[cfg(feature = "hardware-test")]` and is not run in CI.
+
+**Tier 5 — Tier A-HE hardware bench (integration test, COM12)**
+
+Using the ESP32-C6 on COM12 (ruvzen, `MR60BHA2` sensor slot — see CLAUDE.local.md hardware table) associated to an 11ax AP, capture 600 CSI frames (30 seconds at 20 Hz) in the same static room used for Tier 4. Assert:
+- `cir.active_tap_count` is consistent across frames (variance < 1 tap count over 600 frames).
+- `cir.dominant_tap_ratio` > 0.5 (same threshold as Tier 4).
+- `cir.dominant_tap_ratio` averaged over 600 frames is ≥ 20% higher than the Tier 4 S3 baseline from the same room and session — confirming the statistical SNR gain (√(242/52) ≈ 2.16×) from K_active=242 vs K_active=52 (not a conditioning improvement; κ(Φ) ≈ 1 at both tiers).
+- Frame metadata shows PPDU type = HE-SU (not HT20), confirming the C6 is receiving HE-LTF frames (not falling back to Tier A).
+
+This test is gated behind `#[cfg(feature = "hardware-test")]` and is not run in CI. It validates the Tier A-HE preference claim and provides the baseline for any future ADR targeting C6-specific optimisations.
+
+### 2.10 Witness and Proof
+
+Per ADR-028, any new signal stage receives a witness entry. The witness additions for CIR:
+
+**WITNESS-LOG-028.md** — add two rows:
+
+| Row | Capability | Evidence | Hash |
+|-----|-----------|----------|------|
+| W-34 | CIR sparse recovery (synthetic 2-tap, HT20) | `cargo test cir::tests::two_tap_recovery -- --nocapture` output + tap delay error < 1 bin | SHA-256 of stdout |
+| W-35 | CIR phase-ordering correctness | `cargo test cir::tests::phase_corruption_rejected` passes with sanitizer, fails without | SHA-256 of test binary |
+
+**`verify.py` extension**: Add a `cir_recovery_check()` function that feeds the same synthetic two-tap channel through `CirEstimator` via a Python ctypes/cffi shim, computes the dominant-tap delay, and asserts < 1 bin error. Hash the function output and compare to `expected_features.sha256`. This integrates CIR into the deterministic proof chain.
+
+The `source-hashes.txt` in the witness bundle adds the SHA-256 of `ruvsense/cir.rs` alongside the existing firmware binaries.
+
+---
+
+## 3. Consequences
+
+### 3.1 Positive
+
+- **Coherence gate precision**: The `multistatic.rs` coherence gate can now isolate motion to specific delay bins. A body walking across one end of a room no longer corrupts the coherence score of the direct-path tap, eliminating false gate triggers on multi-node links.
+- **Direct-path ranging (Tier B/C)**: At 40 MHz and above, the dominant-tap ToF provides a real range measurement for TDoA triangulation, closing a gap in `triangulation.rs` that currently estimates position from angle-of-arrival only.
+- **Reuses `NeumannSolver`**: Zero new crate dependencies. The ISTA loop wraps the existing solver interface exactly as `fresnel.rs` and `subcarrier.rs` do.
+- **Foundation for ADR-030 and ADR-042**: The persistent field model (ADR-030) requires a per-link CIR baseline for perturbation extraction. The coherent diffraction tomography (ADR-042) requires complex CIR as input. Both are unblocked by this ADR.
+- **Test-harness compatible**: The synthetic test channel plugs directly into the `verify.py` proof infrastructure without new tooling.
+
+### 3.2 Negative
+
+- **Memory cost**: Measured `Vec<Complex32>` allocation per `CirEstimator::new()`: HT20 = 65 KB, HT40 = 312 KB, HE20 = 1.4 MB (see §2.3b). Sharing one `Arc<CirEstimator>` per tier across all same-tier links is mandatory at HE20+; per-link instantiation at 12 HE20 links costs 16.8 MB for sensing matrices alone.
+- **Latency — HT40 12-link budget breach**: Measured median `estimate()` latency: HT20 = 2.72 ms, HT40 = 13.43 ms, HE20 = 3.20 ms (see §2.3b for full table). HT40 at 12-link multistatic sequential = 74.35 ms, which exceeds the 50 ms cycle budget at 20 Hz. HT20 (17.69 ms) and HE20 (est. ~38 ms) both fit. CIR runs on the aggregator, not the ESP32. HT40 multistatic requires Rayon parallelisation (see §2.7). An ESP32-S3 or ESP32-C6 at 240 MHz cannot run any multi-link CIR recovery in the 50 ms budget.
+- **New test fixture**: The two-tap synthetic test requires a `Complex32` construction helper and a tolerance-aware tap-peak detector — ~50 lines of test utility code.
+- **Phase ordering is a hard precondition**: If a caller invokes `CirEstimator::estimate()` on an unsanitized frame, the result is silently wrong (ghost taps, not an error). The `CirError::UnsanitizedPhase` variant provides a partial guard via a heuristic check (phase variance > 10 rad² across subcarriers suggests unsanitized SFO/CFO), but this is not a proof of correctness.
+
+### 3.3 Risks
+
+| Risk | Probability | Impact | Mitigation |
+|------|-------------|--------|------------|
+| `NeumannSolver` convergence at low K with high noise | Medium | Ghost taps in HT20 when channel has few paths and low SNR | κ(Φ) ≈ 1 by construction (normalised DFT submatrix, G = 3K), so numerical ill-conditioning is not the risk. The risk is low SNR at K=52 (2.16× weaker than K=242 at same noise floor). Mitigate with Tikhonov diagonal regularisation (`A + λI`) inside the sensing matrix build step, same as `fresnel.rs:269`, which absorbs residual noise not addressed by measurement averaging. |
+| Dominant-tap ambiguity when LOS is blocked (NLOS-only links) | High at long NLOS ranges | `dominant_tap_idx` points to a reflected path, not direct path | `dominant_tap_ratio` < 0.3 flags this; `ranging_valid` logic gates on ratio > 0.5 |
+| ISTA step-size instability at high λ | Low | Oscillating tap magnitudes across frames | Bound λ to `[1e-4, 0.2]` in `CirConfig` validation; add a step-size line search in the first iteration |
+| ESP32 hardware delivers amplitude-only CSI (no complex) for some firmware versions | Low | `CirError::NoComplexData` at runtime | Firmware audit: `wifi_csi_info_t.buf` in ESP-IDF 5.4 delivers I/Q; document minimum firmware version in `hardware/esp32/README.md` |
+
+---
+
+## 4. Rationale and Comparison to Alternative Designs
+
+### 4.1 Why Not Compute CIR in Python (`archive/v1/`)
+
+The Python pipeline in `archive/v1/src/` is frozen. ADR-011 established that new signal stages go into the Rust workspace, not into the Python archive. The Python proof (`verify.py`) validates the pipeline hash, not the algorithm; its `cir_recovery_check()` extension calls the compiled Rust binary, not Python CIR code.
+
+### 4.2 Why Not Rely on rvCSI Exclusively
+
+`vendor/rvcsi` (ADR-095/096) provides a `CsiFrame`/`CsiWindow`/`CsiEvent` schema and Nexmon adapter, but the published `rvcsi-dsp` crate does not currently implement CIR estimation (as of May 2026 — confirmed by crate source). Even when rvCSI adds CIR, the WiFi-DensePose workspace needs CIR as a first-class type integrated with `CsiFrame` (the `wifi-densepose-core` type), not as a foreign struct requiring FFI translation on every frame at 20 Hz. rvCSI's CIR, when published, can be accepted as an alternative input source by converting to `Cir` at the adapter boundary; the downstream consumers in `multistatic.rs` and `triangulation.rs` will not need to change.
+
+### 4.3 Why Not Frequency-Domain Only Forever
+
+The three research documents (SOTA survey, architecture, edge-weight computation) all converge on the same conclusion: frequency-domain CSI features are sufficient for presence and coarse gesture, but insufficient for:
+
+1. **Tap-isolated coherence gating** (the multistatic coherence gate confounds body motion with environmental drift when both appear as broadband subcarrier modulations).
+2. **Direct-path ranging** (subcarrier phase slope gives bearing, not range, unless combined with a CIR ToF).
+3. **Field normal modes** (ADR-030 requires a per-link CIR baseline to extract structural perturbations from environmental drift).
+
+Deferring CIR indefinitely means these three capabilities remain permanently gated behind the current frequency-domain accuracy ceiling. CIRSense (arXiv:2510.11374, October 2025) independently validates that CIR-domain features yield 3× higher accuracy with 4.5× better computational efficiency compared to raw CSI features for respiration monitoring — the canonical WiFi sensing task in this codebase.
+
+---
+
+## 5. Related ADRs
+
+| ADR | Relationship |
+|-----|-------------|
+| ADR-014 (SOTA Signal Processing) | **Extended**: CIR adds a 7th signal module alongside the 6 in ADR-014 |
+| ADR-017 (RuVector Signal+MAT) | **Enables**: ADR-017's coherence gate pseudocode references CIR; now implementable |
+| ADR-029 (RuvSense Multistatic) | **Unblocks**: `reconstruct_cir()` stub in `process_cycle()` now has a concrete implementation |
+| ADR-030 (Persistent Field Model) | **Prerequisite fulfilled**: baseline CIR per link is required for perturbation extraction |
+| ADR-042 (Coherent Human Channel Imaging) | **Foundation layer**: CHCI's coherent diffraction tomography consumes `Cir` as primary input |
+| ADR-095/096 (rvCSI) | **Complementary**: rvCSI provides the Nexmon adapter for Tier C; CIR estimation runs on top |
+| ADR-028 (ESP32 Capability Audit) | **Witness extended**: two new rows W-34, W-35 added to `WITNESS-LOG-028.md` |
+| ADR-110 (ESP32-C6 Firmware Extension) | **Substrate**: HE-LTF PPDU classification (frame bytes 18–19), TWT wake slots (`c6_twt.c`), and 802.15.4 epoch timestamps (`c6_timesync_get_epoch_us()`) — all shipped in v0.7.0-esp32. Tier A-HE `CirConfig` depends on PPDU type from ADR-110 for automatic tier detection. |

+Searching across the Rust workspace (`v2/crates/**`) for `BaselineCalibration`, `empty_room`, `static_baseline`, and `calibrate` finds no production module that captures an empty-room CSI reference and stores it for real-time subtraction. The closest existing code is `ruvsense/field_model.rs`, which runs an SVD decomposition of calibration frames to extract electromagnetic eigenmodes for ADR-030's drift detection tier. That is a layer above what this ADR addresses: before eigenmodes can be reliably computed, each link needs a per-subcarrier statistical baseline that removes hardware-induced gain bias and environment-fixed multipath from the sensing signal.
+
+The absence is consequential. Three production issues trace directly to missing baseline calibration:
+
+- **False motion triggers** from environmental loading: thermal expansion of walls, HVAC vibration, and furniture reflections cause slow CSI amplitude drift that sits below the motion threshold but corrupts long-window variance estimates. The `ruvsense/coherence_gate.rs` coherence check cannot distinguish this drift from a slowly approaching person.
+- **Phase-coherent algorithms degrade silently**: `CirEstimator` (ADR-134) assumes that the phase-cleaned CSI `H` represents the environmental channel. Without baseline subtraction, `H` also contains the fixed-geometry direct path and primary reflections from walls and furniture. The ISTA solver correctly fits these as low-delay taps, but they consume regularisation budget that should be reserved for body-perturbed taps. `dominant_tap_ratio` is systematically inflated, making NLOS-body detection harder.
+- **Multi-node coherence scores are not comparable**: Without a per-link baseline, the amplitude scale of one ESP32-S3 link at 2.4 GHz differs from another at 5 GHz even in the same room, because RSSI, antenna gain, and cable loss vary per node. Multistatic fusion in `ruvsense/multistatic.rs` applies attention weighting that implicitly assumes comparable amplitude scales across links. Hardware normalization (`hardware_norm.rs`) resamples to a canonical subcarrier grid and applies z-score normalization using population statistics — but those statistics are computed from the full signal including environmental-loading drift, not from a known-empty reference.
+
+ADR-030 (Persistent Field Model, Proposed) describes the SVD-decomposition tier and assumes calibration data exists. ADR-134 (CIR, Proposed) documents at §2.5 that `CirEstimator::set_reference_csi()` should be called "with averaged quiescent frames" — but does not specify how those frames are collected, persisted, or invalidated. This ADR closes that gap.
+
+### 1.2 What "Baseline" Means Here
+
+An empty-room baseline is a per-subcarrier statistical summary of the channel transfer function `H(f_k)` when the room contains no people. It captures:
+
+- The static environment geometry: direct path, wall and furniture reflections, resonances.
+- Hardware-specific gain offsets per subcarrier, which are stable across reboots on the same ESP32 unit.
+- Long-term ambient drift not corrected by `phase_sanitizer.rs` (which operates per-frame, not across frames).
+
+What a baseline is **not**: it is not a calibration for inter-packet phase noise (CFO/SFO), which `phase_sanitizer.rs` and `phase_align.rs` already handle. Those two stages must run before baseline comparison.
+
+### 1.3 Hardware Context
+
+| Tier | Device | Port | Active subcarriers | Bandwidth | Baseline memory (host) |
+|------|--------|------|--------------------|-----------|------------------------|
+| A | ESP32-S3 | COM9 | 52 (HT20) | 20 MHz | ~7 KB per link |
+| A-HE | ESP32-C6 | COM12 | 242 (HE20, STA mode against 11ax AP) | 20 MHz | ~31 KB per link |
+| B | ESP32-S3 | COM9 | 108 (HT40) | 40 MHz | ~14 KB per link |
+
+All hardware runs ADR-110 v0.7.0-esp32 firmware. ESP32-C6 on COM12 provides `c6_timesync_get_epoch_us()` (±100 µs 802.15.4 epoch) for multi-node capture synchronization. The C6 falls back to HT20 when no 802.11ax AP is present; the calibration module detects this from `CsiMetadata.bandwidth_mhz` and selects the appropriate subcarrier mask.
+
+NVS flash budget: ESP32-S3 has 8 MB flash / 4 MB data partition (ADR-028 confirmed). A full Tier A-HE HE20 baseline (242 subcarriers × 4 stats × f32 = ~3.9 KB) fits comfortably in NVS. The NVS key namespace is `ruvcal` with key `b_<link_id>`. Device-side NVS storage is **optional** — the host holds the authoritative baseline in a TOML file and pushes it to device NVS only when fleet-wide simultaneous capture is configured. See Section 2.4.
+
+### 1.4 Pipeline Position
+
+```
+Raw CSI frame
+  → phase_sanitizer.rs  (SFO/CFO removal, per-frame)
+  → phase_align.rs      (LO phase offset, multi-antenna)
+  → CalibrationRecorder::record()   ← NEW (calibration mode only)
+  → BaselineCalibration::subtract() ← NEW (runtime mode)
+  → CirEstimator::estimate()        (ADR-134)
+  → multistatic.rs / motion.rs / vitals
+```
+
+During calibration mode, the `CalibrationRecorder` accumulates frames. At runtime, `BaselineCalibration::subtract()` removes the static environment before the signal enters any downstream consumer. CIR estimation and coherence gating both receive baseline-subtracted CSI.
+
+---
+
+## 2. Decision
+
+### 2.1 Captured Statistics: Minimum Sufficient Set
+
+The baseline captures per-subcarrier **amplitude mean and variance** plus per-subcarrier **circular phase mean and circular variance** (concentration parameter `κ` from the von Mises model). No per-link spatial covariance matrix is captured.
+
+**Amplitude statistics (per subcarrier k, per spatial stream s):**
+- `amp_mean[s][k]`: Welford running mean of `|H[s][k]|`.
+- `amp_m2[s][k]`: Welford M2 accumulator for variance. Variance is `m2 / (n - 1)`.
+
+**Phase statistics (per subcarrier k, per spatial stream s, after sanitization and LO removal):**
+- `phase_sin_mean[s][k]`, `phase_cos_mean[s][k]`: running means of `sin(φ)` and `cos(φ)`. The circular mean is `atan2(phase_sin_mean, phase_cos_mean)`.
+- `phase_circular_variance[s][k]`: `1 - sqrt(phase_sin_mean² + phase_cos_mean²)`, the standard estimator of circular dispersion (Mardia & Jupp, 2000). Range is [0, 1]; 0 = perfectly concentrated, 1 = maximally dispersed.
+
+**What is rejected and why:**
+
+| Statistic | Verdict | Reason |
+|-----------|---------|--------|
+| Per-link spatial covariance (K×K Hermitian) | Rejected | For K=242 (HE20), the full covariance matrix is 242×242×8 bytes = 469 KB per link. Not warranted for a calibration baseline: ADR-030's field model already computes spatial covariance from calibration frames for the eigenmode decomposition. This ADR's baseline is the input to ADR-030, not a substitute for it. |
+| Higher-order moments (skewness, kurtosis) | Rejected | Non-Gaussian amplitude distributions on WiFi subcarriers arise primarily from Rician fading; skewness does not improve motion/person detection at any currently deployed tier. |
+| Cross-subcarrier covariance | Rejected | Same argument as spatial covariance. Off-diagonal entries of the subcarrier covariance encode correlated fading but require 52²/2 = 1,352 entries per stream for HT20 alone, and their incremental value over per-subcarrier variance is not supported by the literature for presence detection. |
+| Time-domain correlation function | Rejected | Belongs to CIR estimation (ADR-134), not to baseline calibration. |
+
+The chosen set — amplitude mean/variance and circular phase mean/variance — is the minimum that enables three downstream operations:
+1. Static-environment subtraction for motion detectors (amplitude mean).
+2. Drift scoring against a known reference (amplitude z-score relative to baseline variance).
+3. Phase-coherent baseline for `CirEstimator::set_reference_csi()` (circular mean gives the expected phase vector for the static environment).
+
+### 2.2 Algorithm: Welford Online, Not Batched
+
+The calibration recorder uses **Welford's online algorithm** (Welford, 1962) for both amplitude and phase statistics. This is the same `WelfordStats` struct already implemented in `ruvsense/field_model.rs` — the calibration module imports it directly.
+
+The alternative — batched mean-of-N (accumulate all frames in memory, compute offline) — is rejected on two grounds:
+
+1. **Memory**: 60 seconds of HE20 frames at 20 Hz = 1,200 frames × 242 subcarriers × 2 streams × 16 bytes = ~9.3 MB of raw complex data. On an embedded aggregator or the Raspberry Pi 5 (cognitum-v0, 8 GB) this is acceptable, but it requires allocating the full buffer before calibration begins, blocking streaming. Welford's algorithm requires O(K × S) state regardless of frame count.
+2. **Streaming interoperability**: Welford allows the recorder to emit a live `deviation_from_partial_baseline()` score that the operator can monitor in real time during calibration, giving feedback that the room is truly empty. Batched computation cannot do this.
+
+For circular phase statistics, Welford's algorithm cannot be applied directly to phase angles (wrap-around violates the linear update assumption). Instead the recorder maintains running sums of `sin(φ)` and `cos(φ)` — a standard technique equivalent to Welford on the unit-circle projection (Fisher, 1993). This is numerically equivalent to the maximum-likelihood estimator for the von Mises concentration parameter under the assumption of a unimodal phase distribution, which holds for a static empty room (no multipath ambiguity).
+
+### 2.3 Capture Duration: 30 Seconds Default, Configurable
+
+The default capture duration is **30 seconds** at the standard 20 Hz sensing rate, yielding 600 frames per spatial stream per subcarrier.
+
+**Justification against alternatives:**
+
+- **60 seconds** (common in the SOTA literature, including Domino arXiv:2509.13807): provides better statistical stability for the circular phase estimate at the cost of doubling operator wait time. With 600 frames, the standard error of the mean amplitude per subcarrier is `σ / √600 < 0.002 × σ` — negligible for sensing purposes at any tier.
+- **10 seconds / 200 frames**: the minimum for a Welford estimate to reach asymptotic variance at typical ESP32 CSI SNR. At 200 frames the circular variance estimate `1 - R̄` has a standard deviation of ~0.04 (Fisher, 1993, Eq. 3.24), corresponding to roughly ±0.04 rad² uncertainty in phase concentration. This is acceptable for amplitude-only downstream stages but degrades the phase-coherent CIR reference. Not the default.
+- **Per-link tradeoff**: a 12-link multistatic room requires 30 s of guaranteed emptiness. Longer captures reduce the practical window in which recalibration is feasible (e.g., during a 30-minute care visit). The 30-second default is the shortest duration that produces a phase-concentration estimate with standard deviation < 0.02 rad².
+
+The `--duration` CLI flag accepts any value from 10 to 600 seconds. Values below 10 seconds are rejected with an error; values above 300 seconds emit a warning.
+
+### 2.4 Persistence Format
+
+**Host-side: TOML**
+
+The authoritative baseline on the host (aggregator, cognitum-v0, or ruvzen Windows box) is stored as a TOML file at the path specified by `--output`. The format is human-readable so operators can inspect and manually flag a stale baseline. Fields are:
+
+```toml
+[meta]
+schema_version = 1
+captured_at_utc = "2026-05-28T14:32:00Z"
+device_id = "esp32s3-com9"
+bandwidth_mhz = 20
+tier = "A"          # A | A-HE | B
+n_streams = 1
+n_subcarriers = 52
+frame_count = 600
+
+[[stream]]
+stream_idx = 0
+
+[stream.amp_mean]   # length = n_subcarriers
+values = [0.421, 0.418, ...]
+
+[stream.amp_variance]
+values = [0.0012, 0.0009, ...]
+
+[stream.phase_cos_mean]
+values = [0.871, 0.864, ...]
+
+[stream.phase_sin_mean]
+values = [0.122, 0.134, ...]
+
+[stream.phase_circular_variance]
+values = [0.031, 0.028, ...]
+```
+
+TOML is chosen over JSON (no comments, awkward for large arrays), bincode (not human-inspectable, format stability risks across serde versions), and rkyv (zero-copy but requires unsafe and pinned schema). The TOML files are small (Tier A: ~8 KB, Tier A-HE: ~40 KB) and load in < 1 ms at runtime. The `toml` crate is already in the workspace (`wifi-densepose-sensing-server/Cargo.toml`).
+
+**Device NVS: little-endian binary**
+
+When `--push-nvs` is passed, the CLI additionally serialises the baseline into a compact binary format and writes it to the device's NVS partition under namespace `ruvcal`, key `b_0` (stream 0). The binary format:
+
+```
+Offset   Size   Field
+0        4      Magic: 0xCA1_1_BA5E (LE u32)
+4        2      Schema version: 1 (LE u16)
+6        2      n_subcarriers (LE u16)
+8        1      n_streams
+9        1      tier (0=A, 1=A-HE, 2=B)
+10       4      frame_count (LE u32)
+14       4×K×S  amp_mean (f32 LE, K×S packed, stream-major)
+14+4KS   4×K×S  amp_variance (f32 LE)
+14+8KS   4×K×S  phase_cos_mean (f32 LE)
+14+12KS  4×K×S  phase_sin_mean (f32 LE)
+14+16KS  4×K×S  phase_circular_variance (f32 LE)
+```
+
+For Tier A (K=52, S=1): total = 14 + 5×52×4 = 1,054 bytes. Well within NVS single-key limits (4,000 bytes default). For Tier A-HE (K=242, S=1): 14 + 5×242×4 = 4,854 bytes — slightly above the default NVS 4,000 byte limit per key. **Resolution**: use two NVS keys (`b_0_amp` for amplitude stats, `b_0_phase` for phase stats), each 2,434 bytes. The CLI serialises to two keys when K×S×4 > 1,980 bytes.
+
+Host and device use different formats because TOML is not parsed on the ESP32 and the binary format would be awkward to inspect on the host. The CLI handles both directions; no device code changes are required.
+
+### 2.5 Stale-Baseline Detection
+
+A baseline becomes stale when the static channel has changed significantly enough that baseline-subtracted frames no longer represent motion-only signals. The two causes are:
+- **Environmental loading**: furniture moved, new appliances added, HVAC pattern change.
+- **Hardware state change**: device rebooted and auto-gain-control settled at a different level; antenna cable degraded.
+
+Detection uses the **Welford z-score of recent frames against the baseline amplitude mean**. At runtime, the `CalibrationDeviationScore` computed by `BaselineCalibration::deviation()` returns a per-subcarrier z-score `z[k] = (|H_live[k]| - amp_mean[k]) / sqrt(amp_variance[k])`. The staleness check aggregates this over time:
+
+```
+drift_score(t) = mean_over_k( median_over_window_W( |z[k,t']|² )  for t' in [t-W, t] )
+```
+
+where the inner `median` operates over a rolling window of W frames. `median` is used instead of `mean` because a single person present during an otherwise empty period should not be flagged as staleness — median suppresses transient occupancy outliers.
+
+**Parameters:**
+- `W = 300 frames` (15 seconds at 20 Hz): long enough to average out occupancy transients, short enough to detect a furniture-rearrangement event within half a minute.
+- Staleness threshold: `drift_score > 4.0`. This corresponds to a mean squared z-score of 4 across all subcarriers, i.e., the amplitude is on average 2σ above the calibration baseline across most subcarriers. This threshold was validated by the field_model.rs team: the `BaselineExpired` error in `field_model.rs` fires at a similar magnitude of environmental shift.
+
+When `drift_score > 4.0` is sustained for `3 × W = 900 frames` (45 seconds), the system emits a `BaselineDrift` event (see §2.6). A single window above threshold triggers a `BaselineWarn` log only.
+
+The 3-window confirmation guard prevents false staleness calls during extended occupied periods (e.g., a person sitting still for 10 minutes will raise z-scores, but is not an indicator of environmental change).
+
+### 2.6 Recalibration Trigger
+
+**Default behaviour: operator-initiated.**
+
+The system does not recalibrate automatically. The operator issues `wifi-densepose calibrate --port COM9 --duration 30 --output baseline.toml` from a terminal, or calls `POST /api/calibrate` on the cognitum-v0 appliance dashboard (`http://cognitum-v0:9000`). Automatic recalibration is a configurable option, not the default, for the following reason: automatic recalibration requires confidence that the room is empty at the time of recalibration. There is no reliable mechanism in the current codebase to verify room emptiness from CSI alone (it is the very thing being calibrated), so automatic recalibration risks capturing an occupied baseline and silently degrading sensing accuracy.
+
+**Configurable modes (all off by default):**
+
+| Mode | Config key | Condition |
+|------|-----------|-----------|
+| Drift-triggered | `recalibrate_on_drift = true` | `drift_score > 4.0` sustained 45 s AND `drift_score < drift_score + 2σ` (i.e., the drift has stabilised, suggesting the room reached a new static state, not that someone is walking around) |
+| Periodic | `recalibrate_period_hours = N` | Every N hours; captures a reference frame silently; requires `--background` mode |
+| API-triggered | always available | `POST /api/calibrate` with optional `duration_secs` body parameter |
+
+When drift-triggered recalibration is enabled, it waits for `drift_score` to plateau (derivative < 0.1 per 30-frame window) before starting capture, using this as a heuristic that the room has stabilised in a new static configuration (furniture moved to a final position, not a person in transit).
+
+The `CalibrationDeviationScore::drift_score` field is published on the sensing WebSocket at `ws://localhost:8765` as a standard sensing field so the cognitum-v0 dashboard and Home Assistant integration (ADR-115) can expose baseline health.
+
+### 2.7 Multi-Tier PHY Handling
+
+An ESP32-C6 may associate as HT20 (Tier A) when no 802.11ax AP is in range, or as HE20 (Tier A-HE) when one is available. The two modes produce different subcarrier counts (52 vs 242 K_active) and different pilot patterns. They are **not interchangeable baselines**.
+
+**Decision: one baseline file per PHY tier per link. Tier change invalidates the existing baseline.**
+
+When the aggregator receives a frame from a C6 link and `CsiMetadata.bandwidth_mhz` and the PPDU type (from ADR-110's `csi_collector.c` frame byte 18–19) indicate a tier different from the currently loaded baseline, `BaselineCalibration::subtract()` returns `CalibrationError::TierMismatch { expected, actual }`. The aggregator logs this at WARN level and falls back to no-baseline-subtraction mode for that link until the operator recalibrates.
+
+The rationale for invalidation rather than interpolation: interpolating a 52-subcarrier baseline to 242 subcarriers (or vice versa) requires assumptions about per-subcarrier correlation that are not validated in this codebase. The hardware-norm resample path (`hardware_norm.rs`) uses Catmull-Rom for subcarrier grid normalisation, but that normalises across hardware types at the same tier — not across tier transitions on the same device.
+
+In practice, tier transitions are rare: they occur when the AP is rebooted (dropping 802.11ax), when the C6 moves out of 11ax AP range, or when the operator changes the AP. The operator is expected to recalibrate after a tier change.
+
+### 2.8 Fleet-Wide Simultaneous Capture
+
+The operator can calibrate the full multistatic array with a single command:
+
+```
+wifi-densepose calibrate --all-nodes --duration 30 --output baselines/
+```
+
+This issues a simultaneous capture barrier across all configured nodes using the 802.15.4 epoch from ADR-110 (`c6_timesync_get_epoch_us()` on C6 nodes; local clock interpolated to 802.15.4 domain for S3 nodes).
+
+**Protocol skeleton:**
+
+1. The CLI sends a `CalibrateStart { start_epoch_us, duration_ms }` UDP control packet to each node's UDP control port (default 5006). Nodes begin accumulating frames from `start_epoch_us` for `duration_ms` milliseconds, tagging each with the 802.15.4 epoch. S3 nodes use their local hardware timer; C6 nodes use `c6_timesync_get_epoch_us()`.
+2. The aggregator simultaneously opens a UDP receive socket per node and applies `CalibrationRecorder::record()` to each incoming frame. Frame ordering within the window is irrelevant because Welford statistics are commutative.
+3. At `start_epoch_us + duration_ms + 500 ms` (500 ms guard for last-frame arrival), the CLI finalises each `CalibrationRecorder`, serialises each `BaselineCalibration` to `baselines/<device_id>.toml`, and optionally pushes NVS binary to each device.
+4. A summary JSON `baselines/summary.json` lists each node, tier, frame count, and the mean `drift_score` relative to any previous baseline, allowing the operator to spot nodes that were occupied during calibration.
+
+Fleet capture requires that all C6 nodes are associated (not in AP setup mode). Seed nodes that have not yet been provisioned (`seed-2` through `seed-5` from CLAUDE.local.md fleet table) are skipped with a warning. `cognitum-seed-1` is the only fully provisioned seed as of this writing.
+
+The 802.15.4 timesync barrier is optional for calibration accuracy (Welford statistics are order-independent) but is required when the calibration baseline will also be used to compute the inter-node phase alignment for ADR-042's CHCI path.
+
+### 2.9 Proposed Rust API

+
+**Design decisions within the API:**
+
+- `record()` takes `&mut self`, not `&self` with interior mutability. The recording path is inherently single-threaded (one receiver loop per link). Interior mutability would add `Mutex` overhead for no benefit.
+- `subtract()` takes `&mut CsiFrame` and modifies `frame.data` in place. It does not modify `frame.amplitude` or `frame.phase` — callers that read `frame.amplitude` downstream are expected to call `CsiFrame::recompute_amplitude_phase()` (a new method to be added to `wifi_densepose_core::types::CsiFrame`) or to use `frame.data` directly.
+- `to_nvs_bytes()` / `from_nvs_bytes()` are fallible via `panic!` for magic mismatch but return `Result` for truncation. This matches the pattern in `csi.rs::parse_esp32_vitals()`.
+- `BaselineCalibration` is `Clone` because the CLI needs to hold one copy while pushing NVS and another while writing TOML.
+
+### 2.10 CLI Surface
+
+The `wifi-densepose calibrate` subcommand is added to `wifi-densepose-cli/src/lib.rs` as a new `Commands::Calibrate(CalibrateCommand)` variant.
+
+```
+wifi-densepose calibrate [OPTIONS]
+
+OPTIONS:
+    --port <PORT>         Serial port or UDP address of the ESP32 node
+                          (e.g., COM9 on Windows, /dev/ttyS8 on WSL).
+                          For fleet mode, omit and use --all-nodes.
+    --duration <SECS>     Capture duration in seconds [default: 30]
+    --output <PATH>       Path to write the TOML baseline file

+    --tier <TIER>         Expected PHY tier: A | A-HE | B
+                          [default: detected from first frame]
+    --push-nvs            After capturing, serialise to NVS binary and
+                          write to device flash via the provisioning tool.
+    --all-nodes           Fleet mode: capture from all configured nodes

+                          baseline at --output and print the drift score.
+```
+
+**Defaults justified:**
+
+- `--duration 30`: justified in §2.3.
+- `--output baseline_<device_id>.toml`: the device ID is embedded in the first received `CsiMetadata.device_id`. The operator does not need to specify it for single-node mode.
+- `--tier detected`: the first frame's `bandwidth_mhz` and PPDU type (for C6) determine the tier. The flag exists for cases where the operator wants to force Tier A even if the device is capable of Tier A-HE (e.g., to pre-generate a fallback baseline).
+
+### 2.11 Downstream Consumers
+
+| Consumer | What it receives | Change required |
+|----------|-----------------|-----------------|
+| `ruvsense/multistatic.rs` | Baseline-subtracted `CsiFrame.data` via `BaselineCalibration::subtract()` | `MultistaticConfig` gains a `baseline: Option<Arc<BaselineCalibration>>` field; `process_cycle()` calls `subtract()` on each node's latest frame before passing to the attention gate |
+| `ruvsense/cir.rs` (ADR-134) | Static-environment reference via `BaselineCalibration::reference_csi_vector()` passed to `CirEstimator::set_reference_csi()` | No API change to `CirEstimator`; the aggregator setup path calls `set_reference_csi()` at startup if a baseline file is present |
+| `motion.rs` | `CalibrationDeviationScore.rms_amplitude_z` as a primary motion signal | Replaces the existing amplitude variance threshold with a baseline-relative z-score; threshold changes from an absolute amplitude variance to `rms_amplitude_z > 3.0` |
+| `features.rs` | `CalibrationDeviationScore` fields available as additional features | `SignalFeatures` gains `baseline_rms_z: Option<f32>` and `baseline_drift_score: Option<f32>` fields; `None` when no baseline is loaded |
+| `wifi-densepose-vitals` | No change | Breathing and heart-rate detection filters operate in the 0.15–2.0 Hz band; slow baseline drift is below 0.001 Hz and is already filtered. The vital-sign pipeline benefits marginally from baseline subtraction at the amplitude level but this is not required for the current implementation. |
+| `ruvsense/field_model.rs` | Calibration frames passed through `CalibrationRecorder` before SVD decomposition | The field model now takes baseline-subtracted frames as input. The Welford mean accumulator in `field_model.rs::FieldModelBuilder` is superseded for the per-subcarrier-mean step — the calibration module handles it. `FieldModelBuilder` ingests `BaselineCalibration` directly to skip its internal mean step. |
+
+**CIR interaction detail**: ADR-134's §2.5 specifies that the `CirEstimator` applies conjugate multiplication using `reference_csi` for single-antenna fallback. `BaselineCalibration::reference_csi_vector()` produces the correct complex reference vector: `amp_mean[s][k] × exp(j × atan2(phase_sin_mean, phase_cos_mean))`. This is more accurate than the previously described approach of averaging quiescent frames on the fly, because the baseline uses 600 frames (30 s) rather than a small number of recent frames, reducing the noise on the reference vector by a factor of ~√600/√10 ≈ 7.7× compared to a 0.5 s on-the-fly average.
+
+### 2.12 Test Plan
+
+**Tier 1 — Deterministic synthetic stationary channel (unit test)**
+
+Generate a synthetic CSI frame representing a static 2-tap channel (direct path + one wall reflection, identical parameters to the ADR-134 Tier 1 test): `H[k] = α₁·e^{-j2πkΔf·τ₁} + α₂·e^{-j2πkΔf·τ₂}`. Add zero-mean Gaussian amplitude noise (σ = 0.02 × |α₁|) and constant phase offset δ = π/8 per subcarrier (simulating LO drift already corrected by `phase_align.rs`). Feed 600 copies of this frame to `CalibrationRecorder`. Call `finalize()`. Assert:
+
+- `baseline.amp_mean[0][k]` is within 2σ/√600 of `|α₁·e^{-j2πkΔf·τ₁} + α₂·e^{-j2πkΔf·τ₂}|` for all k.
+- `baseline.phase_circular_variance[0][k]` < 0.005 (highly concentrated — noise σ = 0.02 does not produce meaningful phase variance).
+- `CalibrationDeviationScore.rms_amplitude_z` for the same static frame is < 1.0 (not flagged as motion).
+
+**Tier 2 — Perturbation detection (unit test)**
+
+Same baseline. Inject one frame with amplitude perturbed at 10 random subcarriers by +3σ (simulating a person present). Assert `rms_amplitude_z > 3.0` and that the perturbed subcarrier indices are among the top-10 `|amplitude_z|` entries in `CalibrationDeviationScore`.
+
+**Tier 3 — TOML round-trip (unit test)**
+
+Serialise the Tier 1 baseline to `to_toml()`, deserialise with `from_toml()`, assert field-level equality to within f32 precision.
+
+**Tier 4 — NVS binary round-trip (unit test)**
+
+Same as Tier 3 using `to_nvs_bytes()` / `from_nvs_bytes()`. Assert magic word `0xCA11BA5E` at offset 0 and schema version = 1.
+
+**Tier 5 — Stale-baseline detection (unit test)**
+
+Start with the Tier 1 baseline. Feed 900 frames with amplitude uniformly increased by `5σ` at all subcarriers (simulating furniture moved). Assert that `CalibrationDeviationScore.baseline_stale` becomes `true` at or before frame 900.
+
+**Tier 6 — Real hardware capture (integration test, COM9)**
+
+Using the ESP32-S3 on COM9 (ruvzen), capture a 30-second baseline in a static empty room. Then capture 200 live frames in the same room (still empty). Assert:
+- `CalibrationDeviationScore.rms_amplitude_z` < 2.0 for all 200 frames.
+- `CalibrationDeviationScore.drift_score` < 1.0.
+- Walking through the room during the live phase: at least 10 consecutive frames show `rms_amplitude_z > 3.0`.
+
+This test is gated behind `#[cfg(feature = "hardware-test")]` and is not run in CI.
+
+**Tier 7 — Determinism proof (CI-compatible)**
+
+To extend the ADR-028 witness proof chain: using the same synthetic 600-frame stream from Tier 1, compute the SHA-256 of `to_nvs_bytes()` output. Record this hash in `archive/v1/data/proof/expected_features.sha256` under the key `calibration_nvs_baseline_v1`. The `verify.py` extension function `calibration_baseline_check()` regenerates the same 600-frame synthetic stream, runs `CalibrationRecorder`, serialises, and asserts the hash matches. This makes the calibration algorithm deterministic end-to-end, consistent with the ADR-028 proof methodology.
+
+### 2.13 Witness / Proof
+
+Per ADR-028, the following rows are added to `docs/WITNESS-LOG-028.md`:
+
+| Row | Capability | Evidence | Hash |
+|-----|-----------|----------|------|
+| W-36 | CalibrationRecorder Welford correctness (synthetic 600-frame stationary) | `cargo test calibration::tests::stationary_baseline -- --nocapture` | SHA-256 of amp_mean output |
+| W-37 | BaselineCalibration NVS binary round-trip | `cargo test calibration::tests::nvs_round_trip` passes | SHA-256 of serialised bytes |
+| W-38 | Drift detection fires within 900 frames (synthetic 5σ perturbation) | `cargo test calibration::tests::stale_detection` | SHA-256 of test binary |
+
+`source-hashes.txt` in the witness bundle gains `SHA-256(ruvsense/calibration.rs)`.
+
+---
+
+## 3. Consequences
+
+### 3.1 Positive
+
+- **Motion detector reliability**: replacing absolute amplitude variance thresholds with baseline-relative z-scores reduces false positives from HVAC and thermal drift. The `rms_amplitude_z > 3.0` threshold is scale-invariant across hardware tiers.
+- **CIR quality improvement**: `CirEstimator` receives a 600-frame static reference rather than a 10-frame rolling average. Ghost taps near τ=0 from the dominant static path are suppressed earlier in the ISTA solve, freeing regularisation budget for body-perturbed taps. Effective `dominant_tap_ratio` dynamic range increases by the ratio `√600/√10 ≈ 7.7×` in reference SNR — the ISTA warm-start quality directly improves.
+- **Multi-node amplitude comparability**: after baseline subtraction, each link's `CsiFrame.data` is zero-centred on the static environment. Multistatic attention weighting can use amplitude magnitude directly without per-link gain normalisation.
+- **ADR-030 field model simplification**: `FieldModelBuilder` no longer needs its own per-subcarrier Welford mean pass; it consumes the finished `BaselineCalibration` and proceeds directly to SVD. Duplicate code is removed.
+- **Fleet-wide recalibration is one command**: the `--all-nodes` flag with 802.15.4 epoch sync enables house-wide calibration in a single 30-second window, closing the operational gap for multi-room deployments.
+
+### 3.2 Negative
+
+- **Calibration ceremony required at install**: operators must capture a 30-second empty-room baseline before the system produces reliable motion scores. Systems shipped without a baseline fall back to uncalibrated mode (no `subtract()` call, absolute variance thresholds). This is not a regression — the current code has no baseline — but it is a new operational step.
+- **Baseline invalidated by furniture changes**: any significant room change (moved sofa, new TV) requires recalibration. The `drift_score > 4.0` alarm notifies the operator, but does not self-heal.
+- **Two NVS keys for Tier A-HE**: the 4,854-byte HE20 baseline does not fit in a single default NVS key. The two-key scheme (`b_0_amp` / `b_0_phase`) adds complexity to the device-side NVS reader if that is ever implemented. For the current scope (host-side reader only), this is not a practical problem.
+- **New `recompute_amplitude_phase()` method needed on `CsiFrame`**: `subtract()` modifies `frame.data` but `frame.amplitude` and `frame.phase` become stale. The method is simple (`amplitude = data.mapv(|c| c.norm()); phase = data.mapv(|c| c.arg())`) but it adds one public API surface to `wifi-densepose-core`.
+
+### 3.3 Risks
+
+| Risk | Probability | Impact | Mitigation |
+|------|-------------|--------|------------|
+| Operator captures baseline with person present | Medium (single-person household) | Silently corrupted baseline; baseline-subtracted frames look like a "hole" where the person was | The CLI prints real-time `rms_amplitude_z` during capture; high z-scores (>2.0) during capture trigger a WARNING banner. Post-capture, `--drift-check` compares against a previous baseline to flag anomalies |
+| Tier change (HT20 → HE20) invalidates baseline mid-session | Medium (C6 nodes near AP boundary) | `TierMismatch` error at runtime; system falls to uncalibrated mode | `TierMismatch` logged at WARN; operator notified via WebSocket event; auto-recalibration configurable |
+| Phase circular variance underestimated for subcarriers with multimodal phase distribution (two equally strong reflected paths at ±π/2) | Low (requires geometric coincidence) | `phase_circular_variance` near 1.0; phase reference from `reference_csi_vector()` is noisy for those subcarriers | `phase_circular_variance > 0.5` per-subcarrier is flagged in the TOML with a comment; CIR estimator down-weights the corresponding rows in Φ by masking them (same mechanism as pilot exclusion in §2.4 of ADR-134) |
+| ESP32-S3 auto-gain-control shifts between baseline capture and runtime | Low (AGC settles within 5 frames) | Amplitude mean baseline offset; all `amp_z` scores biased | AGC-locked mode (`esp_wifi_set_csi_config` with `rx_chain` pin) is available in firmware v0.7.0; recommend enabling for dedicated sensing nodes via `provision.py --pin-agc` flag |
+
+---
+
+## 4. Rationale and Comparison to Alternative Designs
+
+### 4.1 Why Not "Skip Calibration, Rely on Differential Signals Only"
+
+The dominant approach in academic WiFi sensing papers (2018–2022) is to use differential or conjugate-product CSI — dividing each frame by a running average of recent frames — rather than an explicit empty-room baseline. This avoids the calibration ceremony at the cost of three concrete problems in this codebase:
+
+- **Differential signals accumulate bias under environmental loading**. A piece of furniture that moves over 10 minutes produces a slow CSI drift that appears as a 10-minute "motion" event in a conjugate-product system with a 1-second window, or becomes invisible in a system with a 1-hour window. There is no window size that eliminates environmental loading without also suppressing slow human motion (a resting person's micromotion is < 0.01 Hz). The IEEE Transactions 2024 paper "Experimental Evaluation of Long-Term Concept Drift and Its Mitigation in WiFi CSI Sensing" (IEEE Xplore document 10975920) demonstrates that concept drift from environmental factors causes systematic accuracy degradation over hours to days, which no differential window eliminates.
+- **Differential signals cannot be compared across nodes**. Multi-node coherence scoring requires a shared zero-mean reference. If each node has its own differential reference (its own recent history), drift rates differ across nodes and coherence scores are not interpretable.
+- **`CirEstimator` requires an absolute complex reference**. ADR-134 §2.5 describes conjugate multiplication: `H[k] * conj(H_ref[k])`. The `H_ref` in that context must be a stable, long-term static reference to avoid ghost taps — not a 0.5-second recent average, which still contains transient motion in active households.
+
+### 4.2 Why Not "Calibrate at Factory, Ship Coefficients"
+
+Per-device factory calibration would require: (a) a known-geometry, electromagnetically clean test chamber per device, and (b) the firmware to store calibration at production time. ESP32 hardware calibration (PHY RF calibration, `esp_phy_store_cal_data_to_nvs`) is a different concept — it corrects transmit chain IQ imbalance, not the per-room environmental channel. Room geometry is not known at factory. Per-room baseline is the only physically meaningful calibration for ambient sensing applications.
+
+### 4.3 Why Not "Use a Neural Network-Learned Baseline"
+
+Neural baseline subtraction (training a denoising autoencoder on empty-room CSI) has been proposed in several transfer learning papers. The objection from ADR-134 §2.2 for neural CIR applies equally here: there is no paired empty-room dataset for this codebase, and the feature distribution of "empty room" is inherently location-specific. A neural baseline trained in one room may produce negative subtraction values in a different room's frequency-selective geometry. The per-subcarrier Welford mean is a degenerate (optimal) estimator under Gaussian noise: it requires no training data, has a closed-form convergence guarantee, and generalises perfectly to any room because it operates on that room's own captures.
+
+### 4.4 Why Welford Over Exponential Moving Average (EMA)
+
+EMA (`mean_new = α × x + (1 − α) × mean_old`) is simpler to implement and provides continuous adaptation but has two drawbacks for a calibration baseline:
+
+- **α is a free parameter** with no principled setting. Too small an α causes slow adaptation (baseline lags environmental loading); too large adapts immediately to occupancy (person present → person absorbed into baseline → false negative forever).
+- **EMA variance** requires a separate squared-error accumulator and is less numerically stable than Welford at finite precision.
+
+Welford provides the exact sample variance in a single pass with no free parameters and no numerical issues. The existing `WelfordStats` in `field_model.rs` is reused directly. The only EMA advantage (continuous adaptation without a discrete recalibrate event) is a liability here: the baseline must be stable while the room is occupied and only updated on explicit operator command.
+

+
+## 5. Related ADRs
+
+| ADR | Relationship |
+|-----|-------------|
+| ADR-014 (SOTA Signal Processing) | **Extended**: calibration baseline subtraction becomes the zeroth stage of the signal pipeline, before any feature extraction |
+| ADR-028 (ESP32 Capability Audit) | **Witness extended**: three new rows W-36 through W-38 added to `WITNESS-LOG-028.md`; calibration NVS binary hash added to `source-hashes.txt` |
+| ADR-029 (RuvSense Multistatic) | **Enables**: `MultistaticConfig.baseline` field unblocks amplitude-comparable multi-node coherence scoring |
+| ADR-030 (Persistent Field Model) | **Simplified**: `FieldModelBuilder` no longer computes its own per-subcarrier Welford mean; it ingests `BaselineCalibration` as input |
+| ADR-110 (ESP32-C6 Firmware Extension) | **Substrate**: 802.15.4 epoch from `c6_timesync_get_epoch_us()` enables fleet-wide simultaneous capture barrier (§2.8); PPDU type (frame bytes 18–19) enables automatic tier detection for C6 nodes |
+| ADR-115 (Home Assistant Integration) | **Consumer**: `CalibrationDeviationScore.drift_score` and `baseline_stale` are published on the WebSocket stream and picked up by the HA MQTT publisher as `sensor.wifi_baseline_drift` and `binary_sensor.wifi_baseline_stale` |
+| ADR-134 (First-Class CIR Support) | **Prerequisite improved**: `BaselineCalibration::reference_csi_vector()` replaces the on-the-fly quiescent-frame average described in ADR-134 §2.5; CIR ghost taps from the static environment are suppressed more reliably |

+## 1. Color Palette
+
+The entire UI is dark-only. There is no light mode and no `prefers-color-scheme` media query anywhere in the stylesheet. Every surface is drawn from a tight family of near-black navy blues with two accent hues: a cool teal (`--primary`) and a green (`--accent`).
+
+### Core tokens (hex conversions from HSL source)
+
+| CSS variable | HSL value | Hex | Role |
+|---|---|---|---|
+| `--background` | `220 25% 6%` | `#0b0e13` | Page background, modal overlay base |
+| `--foreground` | `210 20% 92%` | `#e6eaee` | Body text, headings |
+| `--primary` | `185 80% 50%` | `#19d4e5` | Teal — active nav underline, CTA borders, ring focus, brand slash |
+| `--primary-foreground` | `220 25% 6%` | `#0b0e13` | Text on filled primary buttons |
+| `--accent` | `142 70% 50%` | `#26d867` | Green — secondary CTA, success state, deploy button text |
+| `--accent-foreground` | `220 25% 6%` | `#0b0e13` | Text on filled accent buttons |
+| `--secondary` | `220 20% 14%` | `#1c212a` | Button fill, pill-tab background |
+| `--card` | `220 20% 10%` | `#14171e` | Card surface (also popover) |
+| `--surface-elevated` | `220 20% 12%` | `#181c24` | Slightly elevated card variant |
+| `--surface-overlay` | `220 20% 8%` | `#111318` | Modal scrim, sticky navbar |
+| `--muted` | `220 15% 15%` | `#20242b` | Muted chip backgrounds, scrollbar track |
+| `--muted-foreground` | `215 15% 55%` | `#7b899d` | Secondary text, labels, timestamps |
+| `--border` | `220 15% 18%` | `#272b34` | All borders (at 50% opacity by default) |
+| `--destructive` | `0 65% 50%` | `#d22c2c` | Error state, danger button |
+| `--ring` | `185 80% 50%` | `#19d4e5` | Focus ring (same hue as primary) |
+
+### Semantic status colors (inline, not variables)
+
+| State | Color | Hex | Usage |
+|---|---|---|---|
+| Online / success | `hsl(142 70% 50%)` | `#26d867` | `.badge.online`, `.dot.up`, `.heat-cell.up` |
+| Warning | `hsl(38 80% 60%)` | `#e69940` | `.badge.unpaired`, `.hero-dot.warn`, banner backgrounds |
+| Error / offline | `hsl(0 65% 50%)` | `#d22c2c` | `.badge.offline`, `.badge.danger`, `.dot.down` |
+| Info (log line) | `hsl(205 80% 65%)` | `#4db8f5` | Log viewer `.info` class |
+| Paired | `hsl(185 80% 50%)` | `#19d4e5` | `.badge.paired` (same as primary) |

+
+## 2. Typography
+
+### Font families
+
+The CSS declares two font families via CSS custom properties:
+
+- `--font-display: 'Outfit', system-ui, sans-serif` — all headings, nav items, buttons, card titles, KPI values. Outfit is a modern geometric sans loaded locally (no Google Fonts outbound call; the source comment says "ship from local chrome.css fallback").
+- `--font-mono: 'JetBrains Mono', monospace` — timestamps, port numbers, version strings, table cells, log output, KPI labels, chip text.
+
+### Type scale
+
+| Token name / usage | Size | Weight | Notes |
+|---|---|---|---|
+| Hero title (`h1.hero-title`) | `clamp(1.5rem, 2.4vw, 2.1rem)` | 600 | Fluid, capped at ~33.6px |
+| Page h1 (`.page`) | `1.5rem` (24px) | 600 | All inner pages |
+| Section heading (`.row-h h2`) | `1.125rem` (18px) | 700 | Section openers on Cogs/Dashboard |
+| Card title (`.card-title`) | `0.9375rem` (15px) | 600 | |
+| Body / button | `0.8125rem` (13px) | 400/500 | Default body, nav links, buttons |
+| Secondary body / lede | `0.875rem` (14px) | 400 | Page lede text |
+| Small label | `0.75rem` (12px) | 400–600 | Table cells, modal sub-text |
+| Micro label | `0.6875rem` (11px) | 600 | Section eyebrows, uppercase KPI labels, badge text |
+| Mono micro | `0.625rem` (10px) | 400 | Heatmap cells, chip category text |
+
+Letter-spacing: `0.1em` on section eyebrows (`.section h2`), `0.08em` on filter-rail headings and chip category text, `-0.02em` on all `h1–h4` display headings. Line-height for body is `1.5`; lede text uses `1.45`.
+
+---
+
+## 3. Layout Primitives
+
+### Page shell
+
+```
+┌─────────────────────────────────────────────────────────┐
+│  .appbar  (sticky, z-50, backdrop-filter:blur(8px))     │
+│  [brand-mark] [brand-text] [nav links scrollable]       │
+├─────────────────────────────────────────────────────────┤
+│  .wrap  (max-width: 1400px, padding: 1.5rem 1.25rem)   │
+│    ┌── .hero (full-width, gradient bg, radial accents) │
+│    ├── .kpi-grid  (auto-fill, min 170px columns)       │
+│    ├── .section > h2 (eyebrow) + content               │
+│    └── .grid / .grid-2 / .grid-3  (auto-fit)          │
+├─────────────────────────────────────────────────────────┤
+│  footer.appfoot  (border-top, centered text)           │
+└─────────────────────────────────────────────────────────┘
+```
+
+**Appbar:** `position: sticky; top: 0; z-index: 50`. Background is the page background at 90% opacity with 8px blur backdrop-filter, so the page content bleeds through. Nav links overflow-scroll horizontally with a right-fade mask gradient.
+
+**Active nav state:** primary-colored text + a 2px bottom border line (`::after` pseudo-element) positioned at bottom: -2px of the link. Hover reveals secondary background fill on the link.
+
+**Content wrap:** max-width 1400px, centered, 1.25rem horizontal padding. Inner page sections are separated by margin-bottom spacing in multiples of 0.75rem (base unit = 12px at 16px root).
+
+### Cogs page: app-store sub-navigation
+
+The Cogs page adds a sticky secondary nav bar (`.subnav`) at `top: 3.25rem` (just below the appbar). Tabs are borderless buttons with a 2px bottom underline indicator when active. A `flex: 1` spacer pushes a gear icon to the right edge.
+
+### Card patterns
+
+Three card variants, all sharing the same surface gradient and border:
+
+1. **Standard card (`.card`)** — `background: var(--gradient-card)` (linear 180deg from `--surface-elevated` to `--surface-overlay`), 1px border at 50% opacity, `--radius` (0.75rem), `box-shadow` 8px/32px dark drop shadow.
+2. **KPI card (`.kpi`)** — 38px icon square left + text right, same gradient, 1rem/1.125rem padding, smaller vertical rhythm.
+3. **Empty-state card (`.empty-card`)** — dashed 1px border (instead of solid), centered text, optional compact variant. The headline in `.empty-card h3` uses the primary teal, body explains what to do next.
+
+### Spacing rhythm
+
+Base unit is 4px. Gaps between grid items are universally `0.75rem` (12px). Card padding is `1.25rem` (20px) for standard, `0.875rem` (14px) for compact. Section margin-bottom is `1.5rem` (24px). The hero section uses `1.75rem` (28px) horizontal padding.
+
+---
+
+## 4. Component Vocabulary
+
+### Navigation components
+
+- **Appbar** — sticky top bar with brand + horizontal nav links. Brand mark is a 32px rounded SVG icon square.
+- **Nav link** — 0.4rem × 0.7rem padding, 0.4rem radius, transitions on color + background. Active state: primary text + 2px underline pseudo-element. Mobile: wraps below brand row at 720px.
+- **Sub-nav / secondary tab bar** (`.subnav`) — app-store style horizontal tab strip, sticky under appbar. Used exclusively on Cogs.
+- **Pill tabs** (`.pill-tabs` + `.pill-tab`) — smaller rounded-rect tab group for in-card filter switching. Active state fills with primary color.
+- **Page tabs** (`.page-tabs`) — used on Analytics for domain view switching. Underline-style, same pattern as sub-nav but at content level.
+
+### Card & data display
+
+- **Card** (`.card`) — base data container with gradient surface, subtle border, shadow.
+- **KPI tile** (`.kpi`, `.kpi-tile`) — metric display with icon, label (uppercase micro mono), large value, and optional sub-line. Two variants: `.kpi` (icon-left layout) and `.kpi-tile` (stack layout, used on Seeds/Edge/AIDefence).
+- **Node card** (`.node`) — cluster member card with mono metadata rows. Key-value pairs in `.node-meta` with dimmed label prefix (`.l` class).
+- **Cog card** (`.cog`) — product-catalog card with emoji icon, name, description, category chips, and a "Get" pill button. Hover lifts 2px with primary glow border.
+- **Pick card** (`.pick-card`) — horizontal-scroll featured card (220px fixed width), snap-scroll container. Smaller emoji + name + category + pill CTA.
+- **Category tile small** (`.cat-tile-sm`) — 180px min-width grid item, emoji + name + count.
+- **Category tile large** (`.cat-tile-big`) — 16:9 aspect-ratio card, full-bleed with gradient per category.
+- **Nav tile** (`.nav-tile`) — dashboard home navigation card with icon square, title, description, and a chevron arrow that translates +2px on hover.
+- **Architecture action card** (`.arch-card`, `.arch-action-card`) — setup wizard launcher cards on the dashboard.
+
+### Status & feedback
+
+- **Badge** (`.badge`) — pill with 1px border, 11px mono text. Variants: `role-master` (teal), `role-worker` (green), `online` (green), `offline` (red), `unknown` (muted), `paired` (teal), `unpaired` (amber), `danger` (red).
+- **Dot** (`.dot`) — 8px circle status indicator. `.up` glows green with box-shadow, `.down` is red, default is muted gray.
+- **Hero dot** (`.hero-dot`) — 7px circle in the dashboard hero status row. Same three states: `.ok` (green glow), `.warn` (amber glow), `.down` (red glow).
+- **Op-pill** (`.op-pill`) — "operational status" pill with colored dot inside. Used in dashboard architecture hub.
+- **AI pill / status chip** (`.pill` on AIDefence, `.md-badge` in cluster) — inline classification badge at 0.68rem. States: `.ok`, `.warn`, `.bad`.
+- **Chip** (`.chip`) — tiny category/difficulty label, all-caps, 0.5625rem, pill-shaped. Category-colored variants (`.cat-ai`, `.cat-health`, `.cat-security`, etc.) each get a hue-appropriate 15% opacity background.
+
+### Actions
+
+- **Button** (`.btn`) — 0.5rem × 0.875rem padding, 0.4rem radius, secondary fill. Variants: `.primary` (filled teal, 600 weight, box-shadow), `.outline` (transparent fill), `.danger` (red tint), `.sm` (compact).
+- **Hero button** (`.hero-btn`) — slightly larger, display-font, 0.9rem padding, glass-effect dark fill. `.primary` variant uses the green accent gradient.
+- **Pill CTA** (`.get`, `.pget`) — full pill-radius (9999px), primary-tint background at rest, fills solid on hover. Used on cog cards and pick cards.
+- **Gear button** (`.gear-btn`) — icon-only square button, transparent at rest, border appears on hover.
+- **Context menu** (`.ctx-menu`) — dark card dropdown (min-width 180px), each item is a full-width button with secondary hover fill.
+- **Copy button** (`.copy-btn`) — positioned absolute in `.copy-row`, 0.7rem opacity at rest, `.copied` state turns green/accent.
+
+### Forms & inputs
+
+- **Input** — all `<input>`, `<textarea>`, `<select>` inherit dark theme globally. Focus ring: 2px solid primary at 30% opacity (`box-shadow: 0 0 0 2px hsl(var(--ring) / 0.3)`). Checkboxes and radios use `accent-color: hsl(var(--primary))`.
+- **Collapsible section** (`.coll`, `.coll-h`, `.coll-body`) — used in Settings page. Header row is clickable with `user-select: none`. Body `display: none` by default, revealed on expand.
+- **Key-value row** (`.kv`) — 3-column grid (160px label | 1fr value | auto action) for settings display.
+- **Filters rail** (`.filters-rail`) — sticky sidebar on Cogs/Apps tab. Sticky at `top: 7rem` (below both navbars). Contains checkboxes, a range input, and a reset button.
+- **Range input** — native `<input type="range">` styled with `accent-color: hsl(var(--primary))`.
+
+### Data visualization
+
+- **Heatmap** (`.heatmap`) — CSS grid of 14px × variable cells. 60 time columns, label column at 90px. Cell states: `up` (green 70%), `down` (red 70%), `empty` (muted 30%).
+- **Bar chart** (`.bar-list` + `.bar-row` + `.bar-fill`) — horizontal bar list, 3-col grid (120px label | 1fr bar | 30px value). Bar fill transitions width in 0.3s.
+- **uPlot time-series** (`.uplot-host`) — 200px height host container; actual charting via uPlot library.
+- **Three.js 3D** — importmap for `three` + `OrbitControls` in Analytics page, for 3D sensor visualization.
+- **Log box** (`pre.logbox`) — monospace pre-formatted block, max-height 30rem, overflow-y scroll. Dark background on dark background gives subtle separation via border.
+- **OTA row table** (`.ota-row`) — 3-col grid (160px | 80px | 1fr) for firmware OTA records.
+
+### Overlays
+
+- **Modal** (`.modal-bg` + `.modal`) — fixed inset, 70% opacity blur-backdrop scrim. Modal itself is card-surfaced, max-width 560px. Result states: `.modal-result.ok` (green tint) and `.modal-result.err` (red tint).
+- **Detail modal** (`.detail-modal-bg` + `.detail-modal`) — larger variant (max 820px, 2rem padding) used on Cog detail view. Header has emoji, name, meta chips; sections below are tabbed.
+- **Keyboard shortcut tag** (`.kb`) — small monospace tag with secondary background, used inline in Settings and Tailscale pages to show keyboard shortcuts.
+
+---
+
+## 5. Iconography
+
+All icons are inline SVG, 24×24 viewBox, `fill: none`, `stroke: currentColor`, `stroke-width: 2`. The path geometry is **Lucide Icons** — confirmed by comparing the Sun/gear/shield/grid/activity paths against Lucide's source. Key examples observed:
+
+- Sun/rays (brand mark, dashboard hero)
+- Settings/gear (nav, subnav gear button)
+- Activity/pulse (KPI signal icon)
+- Bar chart 3 (analytics KPI)
+- Grid 2×2 (cluster/cog layout)
+- Shield with checkmark (AIDefence)
+- House (home nav tile)
+- Book-open (guide nav)
+
+No external icon font is used. Every icon is self-contained in the HTML at point of use — no sprite sheet.
+
+---
+
+## 6. Dark Mode
+
+The design is **dark-only**. There is no `prefers-color-scheme: light` media query in `v0-chrome.css` or any page-level stylesheet. The color system is entirely designed around the dark palette above. The source comments explicitly note that `fonts.googleapis.com` is blocked for Tailnet isolation, reinforcing that this is an always-dark appliance UI, not a consumer product that needs theming.
+
+Surface hierarchy (light to dark, within the dark palette):
+1. `--surface-elevated` (`#181c24`) — slightly lighter card variant
+2. `--card` (`#14171e`) — standard card
+3. `--surface-overlay` (`#111318`) — modal/sticky appbar base
+4. `--background` (`#0b0e13`) — page root
+
+The appbar uses `background: hsl(var(--background) / 0.9)` + `backdrop-filter: blur(8px)` so content underneath bleeds through as a translucency effect.
+
+---
+
+## 7. Notable Interactions
+
+- **Nav hover:** 150ms color + background transition, no translate. Active state uses a 2px pseudo-element underline that animates in via opacity.
+- **Nav link active press:** `transform: translateY(1px)` on `:active` at 50ms — very subtle tactile response.
+- **Card hover:** `transform: translateY(-2px)` at 200ms on cards and cog items. Border shifts from `--border/0.5` to `primary/0.4` on hover. On the nav tiles, box-shadow deepens.
+- **Hero button hover:** `transform: translateY(-1px)` + border-color shift to primary at 70%.
+- **Pick card hover:** translateY(-2px) + primary-glow box-shadow.
+- **Focus ring:** 2px solid primary at 30% opacity as box-shadow — uses `outline: none` everywhere and replaces it with the ring shadow. nav links use `outline: 2px solid hsl(var(--primary)/0.6); outline-offset: 1px` for focus-visible.
+- **Bar fill animation:** `transition: width 0.3s` on bar chart fill elements for data-load entrance.
+- **Modal backdrop:** `backdrop-filter: blur(4px)` on modal scrim, `blur(6px)` on the Cog detail modal.
+- **Copy button feedback:** `.copied` state class swaps border and text to accent green, visible for a short duration (JS-controlled).
+- **Pill CTA:** Background fills from 15% opacity teal to 100% solid on hover — a strong affordance for primary actions.
+- **Scroll fade mask:** The nav bar has `mask-image: linear-gradient(to right, black calc(100% - 24px), transparent)` to fade out the rightmost item, hinting at horizontal scroll.
+- **Cogs hero carousel:** Paginator dots expand from 0.55rem circles to 1.5rem pill shape (border-radius 0.4rem) when active — a distinctive indicator pattern.
+
+---
+
+## 8. HA-Parity Opportunities
+
+For ADR-131 P2, the following comparisons are relevant between this design and Home Assistant's frontend (`home-assistant-main`):
+
+| HOMECORE component | Cognitum V0 pattern | HA equivalent | Better reference |
+|---|---|---|---|
+| KPI metric card | `.kpi` — icon + label + value | `ha-statistic-card`, `sensor-badge` | **Cognitum** — cleaner dense layout; HA's is more verbose |
+| Status badge/pill | `.badge` + `.chip` — pill with 1px border | `ha-label-badge`, `state-badge` | **HA** — HA has more state variants and i18n built in |
+| Dark surface cards | `--gradient-card` linear gradient | HA uses flat `var(--card-background-color)` | **Cognitum** — gradient gives depth HA lacks |
+| Toggle/switch | `accent-color` native checkbox | HA `ha-switch` (Material) | **HA** — purpose-built, accessible, animated |
+| Navigation | Horizontal sticky nav, underline indicator | HA sidebar (vertical) | Neither — HOMECORE needs a new shell; Cognitum's horizontal bar is appropriate for appliance context |
+| Heatmap timeline | CSS grid `.heatmap` | No HA equivalent | **Cognitum** — take this pattern directly |
+| Bar chart | CSS-only `.bar-fill` bar list | HA uses Recharts | **Cognitum** — zero-dep CSS bars good for simple metrics; use for small cards |
+| Time-series chart | uPlot `.uplot-host` | HA uses ApexCharts / Recharts | **HA** — ApexCharts has more features, better RTL support |
+| Modal | `.modal-bg` blur-backdrop | HA `ha-dialog` (Material) | **HA** — a11y and focus-trap already solved |
+| Toast / alert banner | `.modal-result.ok/err` inline result + `.cl-banner.warn/err` | HA `ha-alert` | **HA** — HA's alerts are more composable |
+| Focus ring | `box-shadow` ring pattern | HA uses `:focus-visible` outline | **HA** — HA's approach has better browser compatibility |
+| Chip (category) | `.chip.cat-*` per-category color mapping | HA `ha-chip` | **Cognitum** — the category-specific hue mapping is richer |
+
+---
+
+## 9. Design Tokens for HOMECORE-FRONTEND P1
+
+Concrete CSS variable names and starting values for the TypeScript+WASM frontend to adopt. These follow the Cognitum V0 source directly, adjusted where needed for HOMECORE context.
+

+}
+```
+
+**Notes for P1 implementation:**
+
+- Adopt Outfit + JetBrains Mono from Google Fonts in development; ship local fallbacks for production (Tailnet appliances block outbound font requests per the Cognitum source comment).
+- The `--hc-ring` focus approach should be implemented as `box-shadow: 0 0 0 2px hsl(var(--hc-ring) / 0.3)` combined with `outline: none` — matches Cognitum's pattern and avoids the offset-gap issue in Firefox.
+- Add `--hc-gradient-hero` and `--hc-gradient-glow` when the dashboard hero section is built; keep them out of the P1 design-token foundation to avoid premature complexity.
+- The `--hc-warning` amber is not in the Cognitum `:root` block (it is inline throughout) — elevating it to a token is a deliberate improvement for HOMECORE.

+# HOMECORE Security Audit — Iter-10
+
+**Branch**: `feat/adr-126-homecore-impl`  
+**Audit date**: 2026-05-25  
+**Scope**: 8 new crates + integration binary (iter-1 through iter-9)  
+**Auditor**: Security-audit agent (claude-sonnet-4-6)
+
+---
+
+## Executive Summary
+
+HOMECORE's Rust codebase is structurally sound but ships with two pre-production
+placeholders that are critical blockers for any production deployment: the HTTP
+bearer-token validator accepts **any non-empty string as a valid token**, and the
+WebSocket auth handshake does the same. Every protected endpoint is therefore fully
+open to unauthenticated attackers who can reach port 8123.
+
+`cargo audit` flagged **18 advisories** across three dependency trees. Two are
+Critical (CVSS 9.0): both are Wasmtime sandbox-escape bugs in the Winch and
+Cranelift compiler backends (RUSTSEC-2026-0095/0096). SQLx 0.7.4 carries a
+binary-protocol misinterpretation bug (RUSTSEC-2024-0363). The Wasmtime
+version must be upgraded before any WASM plugin is loaded in production.
+
+Additional findings: `CorsLayer::permissive()` allows cross-origin requests from
+any domain; the HAP service record hardcodes a predictable setup code and a
+broadcast MAC address; `hc_log` writes plugin output directly to `eprintln!`
+without going through `tracing`; and the WS `subscribe_events` command has no
+per-connection subscription cap, enabling a resource-exhaustion DoS.
+

+| HC-01 | **Critical** | Bearer auth accepts any non-empty token (REST) | `homecore-api/src/auth.rs:25` and `rest.rs` (all handlers) | `BearerAuth::from_headers` returns `Ok` for any non-empty string. All REST endpoints (`/api/config`, `/api/states`, `/api/services`, `call_service`) are fully open to any caller. | Implement a token store in P2 before deployment. Until then, enforce network-level ACL so port 8123 is unreachable from untrusted networks. |
+| HC-02 | **Critical** | WebSocket auth handshake accepts any non-empty token | `homecore-api/src/ws.rs:61–68` | The WS `auth` phase validates only that `access_token` is non-empty. After passing this check the client reaches the full command loop including `call_service`. An attacker sending `{"type":"auth","access_token":"x"}` gets a fully authenticated session. | Same as HC-01; block at network until real token store is wired. |
+| HC-03 | **Critical** | Wasmtime 25.0.3 — sandbox-escape via Winch backend (RUSTSEC-2026-0095) | `homecore-plugins/Cargo.toml` | The Winch compiler backend in Wasmtime 25.0.3 allows a sandboxed WASM plugin to perform out-of-sandbox memory writes (CVSS 9.0). | Upgrade `wasmtime` to `>=36.0.7` or `>=42.0.2`. |
+| HC-04 | **Critical** | Wasmtime 25.0.3 — sandbox-escape via miscompiled heap access on aarch64 Cranelift (RUSTSEC-2026-0096) | `homecore-plugins/Cargo.toml` | Miscompiled guest heap access in Cranelift's aarch64 backend enables sandbox escape (CVSS 9.0). Production Pi 5 targets are aarch64. | Upgrade `wasmtime` to `>=36.0.7` or `>=42.0.2`. |
+| HC-05 | **High** | `CorsLayer::permissive()` allows all cross-origin requests | `homecore-api/src/app.rs:25` | `CorsLayer::permissive()` sets `Access-Control-Allow-Origin: *` and allows all methods and headers. Any webpage on any origin can make authenticated API calls using a stored bearer token (when HC-01/02 are fixed). | Replace with an explicit allowlist: `CorsLayer::new().allow_origin(expected_origin).allow_methods([GET, POST])`. |
+| HC-06 | **High** | SQLx 0.7.4 — binary protocol misinterpretation (RUSTSEC-2024-0363) | `homecore-recorder/Cargo.toml` | Truncating/overflowing casts in SQLx 0.7.4's binary protocol handling can cause values to be misread. Although HOMECORE only uses SQLite (not MySQL/Postgres), the vulnerable codepath is in the shared crate. | Upgrade `sqlx` to `>=0.8.1`. |
+| HC-07 | **High** | No per-connection subscription cap on WS `subscribe_events` | `homecore-api/src/ws.rs:237–295` | A single authenticated WS connection can call `subscribe_events` in an unbounded loop. Each subscription spawns a Tokio task and takes one broadcast receiver slot. With the bus capacity at 4096 slots, a malicious client can exhaust OS thread/task resources before the bus fills. | Add a per-connection subscription ceiling (e.g., 50). Reject further `subscribe_events` commands with `"too_many_subscriptions"`. |
+| HC-08 | **High** | Hardcoded HAP setup code and broadcast MAC in production binary | `homecore-server/src/main.rs:113–114`, `homecore-hap/src/bridge.rs:143–144` | The integration binary hard-codes `setup_code: "123-45-678"` and `device_id: "AA:BB:CC:DD:EE:FF"`. When real HAP pairing lands in P2 any attacker on the local network can pair with the bridge using the published setup code; the broadcast MAC address is also invalid per the HAP specification. | Generate a random setup code and a locally administered unicast MAC at startup (or require them as CLI arguments). Never use a known-fixed setup code. |
+| HC-09 | **Medium** | Wasmtime 25.0.3 — 11 additional medium/low CVEs | `homecore-plugins/Cargo.toml` | RUSTSEC-2025-0046, -0118, -2026-0020, -0021, -0085, -0086, -0087, -0088, -0089, -0091, -0092, -0093, -0094 affect resource exhaustion, host data leakage, OOB reads/writes, and panics. All are fixed in wasmtime `>=36.0.7`. | Same fix as HC-03/04: upgrade wasmtime. |
+| HC-10 | **Medium** | `hc_log` writes plugin output via `eprintln!` bypassing structured logging | `homecore-plugins/src/wasmtime_runtime.rs:297` | Plugin log messages are written directly to stderr via `eprintln!`, bypassing the `tracing` subscriber. This means: (a) log level filtering does not apply to plugin output; (b) log aggregation pipelines (e.g., JSON structured logs) miss plugin messages. A verbose or malicious plugin can flood stderr. | Replace `eprintln!` with `tracing::debug!/info!/warn!/error!` using the already-imported `LogLevel`. |
+| HC-11 | **Medium** | No size bound on `set_state` body or `attributes` JSON | `homecore-api/src/rest.rs:95–108`, `ws.rs:222–235` | `POST /api/states/:entity_id` and the WS `call_service` / `get_states` paths accept a `serde_json::Value` body with no size limit beyond Axum's default (2 MB). Specially crafted deeply-nested JSON can cause quadratic parse time or high-memory allocation during serialization. | Apply `axum::extract::DefaultBodyLimit::max(65536)` on the route or globally; validate JSON depth before accepting. |
+| HC-12 | **Medium** | `rsa 0.9.10` — Marvin Attack timing side-channel (RUSTSEC-2023-0071) | transitive via `sqlx-mysql 0.7.4` | The `rsa` crate's decryption is vulnerable to timing-based key recovery. Pulled in by `sqlx-mysql` even though HOMECORE only uses SQLite. No fix is available upstream. | Add `sqlx` features `sqlite` only (remove `mysql`/`postgres` from the feature list) to avoid pulling in `sqlx-mysql` and the `rsa` transitive dependency. |
+| HC-13 | **Medium** | `shlex 0.1.1` — shell-injection via quote API (RUSTSEC-2024-0006) | transitive via `wasm3-sys 0.3.0 → wasm3 0.3.1 → homecore-plugins` | `shlex`'s quote function can produce unsafe shell strings. Pulled in by the `wasm3` build system. Not directly callable from HOMECORE Rust code but present in the binary's dependency tree. | Upgrade `shlex` to `>=1.3.0` or drop the `wasm3` dependency if `WasmtimeRuntime` is the production path. |
+| HC-14 | **Low** | No TLS on the HTTP/WS listener | `homecore-server/src/main.rs:122–128` | The Axum listener binds plain TCP (`axum::serve`). Bearer tokens and all home automation data are transmitted in cleartext. On LAN deployments an attacker with ARP poisoning can intercept credentials. | Add `rustls`/`axum-server` TLS termination or document that a TLS-terminating reverse proxy (nginx/Caddy) is required. |
+| HC-15 | **Low** | Migration CLI performs no symlink/traversal check on `.storage/` path | `homecore-migrate/src/storage.rs:36–37`, `main.rs:14–32` | `HaStorageDir::file_path` calls `self.path.join(name)` where `name` comes from hard-coded constants, so exploitation requires the `--storage` argument itself to point outside the intended tree. There is no `Path::canonicalize` + prefix check. While the current filenames are constants, if P2 makes `name` data-driven the surface widens. | Add `path.canonicalize()` + assert prefix after computing `file_path` if the name ever becomes user-controlled. Document this as a P2 gate. |
+| HC-16 | **Low** | `AutomationEngine` uses `eprintln!` for action errors | `homecore-automation/src/engine.rs:93–95, 105` | Action errors and lag notices are emitted via `eprintln!`, not `tracing::warn!`. Same issues as HC-10: bypasses structured logging. | Replace with `tracing::warn!`/`tracing::error!`. |
+| HC-17 | **Informational** | WS `call_service` authorization is contingent on fixing HC-01/HC-02 | `homecore-api/src/ws.rs:222–235` | `call_service` (including destructive calls such as `homeassistant.restart`) sits behind the WS auth handshake. Once HC-01 and HC-02 are fixed this path is properly guarded. No additional change needed here beyond those fixes. | No action required beyond HC-02. |
+| HC-18 | **Informational** | `hc_state_subscribe` accumulates entity strings without eviction | `homecore-plugins/src/wasmtime_runtime.rs:263–268` | The `PluginStoreData.subscriptions` Vec grows without bound if a plugin repeatedly subscribes to the same entity. There is no deduplication. This is a plugin-local memory leak, not a sandbox escape. | Deduplicate on insert: `if !caller.data().subscriptions.contains(&eid)`. |
+
+---
+
+## Negative-Result Section (Surfaces Checked and Found Clean)
+
+**SQL injection (homecore-recorder/src/db.rs)**: All queries use `sqlx::query`
+with positional `?` bind parameters. No `format!`-constructed SQL was found in
+any path (`record_state`, `record_event`, `get_state_history`, `search_semantic`,
+`apply_schema`). Clean.
+
+**WS bearer token in logs/error messages**: The bearer token is extracted and
+immediately discarded after the non-empty check at ws.rs:62. It is not passed
+to any `tracing` macro, `eprintln!`, or error-display path. The `access_token`
+field is not part of any `Debug`-derived struct that enters a log path. Clean.
+
+**REST bearer token in logs/error messages**: `BearerAuth(token)` is `Debug`
+but no handler logs it or includes it in an error response. `ApiError` variants
+do not capture the token. Clean.
+
+**WASM linear-memory buffer overflow in `hc_state_get`/`hc_state_set`**: The
+`read_str` helper validates `len < 0` and `len > MAX_ABI_BUFFER_BYTES (65536)`
+before slicing, and uses `mem.get(ptr..ptr+len)?` which cannot panic. In
+`hc_state_get` phase 3, the write is guarded by `json_bytes.len() > out_cap`
+before attempting the slice. The `call_export_str` host-to-guest path also uses
+`.get_mut(ptr..ptr+len).ok_or_else(...)` rather than unchecked indexing. No
+buffer-overflow vector identified in the host ABI.
+
+**WASM JSON ABI escape**: Plugins receive and emit plain UTF-8 JSON strings via
+the linear-memory ABI. The host deserializes attribute JSON with
+`serde_json::from_str` and defaults to `{}` on parse failure — no panic path.
+No mechanism for a plugin to escape the Cranelift JIT sandbox via the JSON layer
+alone was identified; the sandbox-escape risk is in the Cranelift/Winch compiler
+backends (HC-03/04).
+
+**Path traversal in homecore-migrate**: All `.storage/` filenames are currently
+hard-coded constants (`"core.entity_registry"`, `"core.device_registry"`, etc.)
+in the Rust source. The `--storage` and `--config-dir` arguments are user-supplied
+but refer to the directory root, not individual filenames. No user-controlled
+string is concatenated into a file path. Clean at P1 scope (noted as a P2 gate in HC-15).
+
+**DoS via event-bus flood from a plugin**: A WASM plugin can call `hc_state_set`
+in a tight loop. Each call fires a `broadcast::Sender::send` on the system channel
+(capacity 4096). When the channel is full, `send` returns 0 (receivers are
+dropped/lagged) but does not block or panic. Lagged receivers are notified via
+`RecvError::Lagged`. The state machine itself does not back-pressure the sender.
+The flood can cause the recorder and automation engine to lag, but it cannot crash
+the host process. Noted as design-level concern; acceptable for P1.
+
+**Secrets leakage in homecore-migrate InspectSecrets**: The CLI correctly prints
+`<redacted>` for secret values and only logs key names.
+
+---
+
+## Critical-Path Remediation List (Required Before Production Deployment)
+
+The following items MUST be resolved before `homecore-server` is reachable from
+any untrusted network:
+
+1. **HC-01 + HC-02 (Critical)** — Implement the token store and validate bearer
+   tokens in both `BearerAuth::from_headers` and the WS `handle_socket` auth
+   phase. Until this is done every REST and WS endpoint is completely open.
+
+2. **HC-03 + HC-04 (Critical)** — Upgrade `wasmtime` in `homecore-plugins/Cargo.toml`
+   from `25.0.3` to `>=36.0.7` (or `>=42.0.2`). The current version has two
+   confirmed CVSS-9.0 sandbox-escape bugs; loading any third-party WASM plugin
+   on the current version cannot be considered safe.
+
+3. **HC-06 (High)** — Upgrade `sqlx` from `0.7.4` to `>=0.8.1` to eliminate the
+   binary-protocol misinterpretation bug.
+
+4. **HC-05 (High)** — Replace `CorsLayer::permissive()` with an explicit
+   origin allowlist before any browser-accessible deployment.
+
+5. **HC-08 (High)** — Replace the hardcoded HAP setup code and broadcast MAC
+   address with randomly generated values before P2 real HAP pairing lands.
+
+6. **HC-07 (High)** — Add per-connection subscription limit to the WS command
+   loop before exposing the server to untrusted LAN clients.

+# @ruvnet/homecore-frontend
+
+HOMECORE web UI — built with Lit 3, TypeScript, and Vite.
+Design system mirrors the cognitum-v0 / v0-appliance dashboard (ADR-131).
+
+## Quick start
+
+```bash
+cd frontend
+npm install
+npm run dev          # http://localhost:5173
+```
+
+The Vite dev server proxies `/api` → `http://localhost:8123`, so you need a
+`homecore-api-server` (or the `wifi-densepose-sensing-server` crate) running on `:8123`.
+
+## Scripts
+
+| Script | Description |
+|--------|-------------|
+| `npm run dev` | Start Vite dev server on port 5173 |
+| `npm run build` | TypeScript compile + Vite production bundle → `dist/` |
+| `npm run lint` | ESLint on `src/` |
+| `npm test` | Vitest unit tests (3 suites, jsdom) |
+
+## Package layout
+
+```
+frontend/
+  src/
+    api/
+      client.ts        # fetch + WebSocket client (REST + WS)
+      types.ts         # TypeScript types matching homecore-api JSON shapes
+    components/

+  tsconfig.json
+  vitest.config.ts
+```
+
+## Design system
+
+Colors, typography, and components mirror the cognitum-v0 dashboard
+(`http://cognitum-v0:9000/`). Dark-only; no light-mode. Key tokens:
+
+- `--hc-primary` `#19d4e5` — teal (active nav, focus ring, CTA borders)
+- `--hc-accent` `#26d867` — green (success, secondary CTA)
+- `--hc-bg` `#0b0e13` — near-black navy page root
+- Font: Outfit (display) + JetBrains Mono (mono)
+- Icons: Lucide (SVG, `stroke: currentColor`, no icon font)
+
+See `docs/design/HOMECORE-FRONTEND-design-recon.md` for the full recon.
+
+## Architecture notes
+
+- Components are standard Lit `LitElement` custom elements — compatible with
+  any HTML page and with Home Assistant's Lit-based frontend.
+- The REST client uses `fetch`; the WS client uses `WebSocket`. Both accept a
+  bearer token and are fully typed against the Rust `homecore-api` JSON shapes.
+- WASM: `vite.config.ts` enables `.wasm` asset import. Hook up via dynamic
+  `import('/path/to/module.wasm?init')` when WASM bindings are ready.

+
+Wire-compatible Axum REST + WebSocket server that mirrors Home Assistant's `/api/` routes. Ships a standalone binary (`homecore-api-server`) and a library for embedding in other applications.
+
+## What this crate does
+
+`homecore-api` provides the HTTP boundary layer for HOMECORE. It wires Axum routes to the `homecore` state machine, exposing:
+
+- **GET `/api/states`** — list all entity states
+- **GET `/api/states/:entity_id`** — fetch a single entity's state + attributes
+- **POST `/api/states/:entity_id`** — update an entity's state and attributes
+- **GET `/api/services`** — list registered services
+- **POST `/api/services/:domain/:service`** — call a service with arguments
+- **GET `/api/websocket`** — upgrade to WebSocket for real-time state + event streaming
+- **Bearer token authentication** — validates long-lived access tokens from a token store
+
+All routes return HA-compatible JSON and validate `Authorization: Bearer <token>` headers (except the WS upgrade, which validates the token as a query param for browser compatibility).
+
+## Features
+
+- **HA-compatible JSON schema** — `/api/states` returns `[{"entity_id": "...", "state": "...", "attributes": {...}}]` matching HA exactly
+- **REST CRUD operations** — GET, POST, DELETE entities with automatic `last_updated` and `last_changed` timestamps
+- **WebSocket streaming** — subscribe to state changes in real-time with topic-based filtering (`type:state_changed`, etc.)
+- **Explicit CORS allowlist** — configurable via `HOMECORE_CORS_ORIGINS` env var (audit fix HC-05); defaults to `localhost:5173` (frontend dev), `localhost:8123` (HA port)
+- **Bearer token validation** — long-lived tokens stored in memory (upgrade to Redis/SQLite in P2)
+- **Error responses as JSON** — 400/401/404/500 with `{"error": "...", "message": "..."}` envelopes
+- **Request tracing** — tower-http TraceLayer logs all requests (configurable via `RUST_LOG`)
+
+## Capabilities
+
+| Capability | Method | Endpoint | Returns |
+|------------|--------|----------|---------|
+| List all entities | GET | `/api/states` | `[{entity_id, state, attributes, last_changed, ...}]` |
+| Get single entity | GET | `/api/states/:entity_id` | `{entity_id, state, attributes, last_changed, ...}` or 404 |
+| Set entity state | POST | `/api/states/:entity_id` | updated state object |
+| Delete entity | DELETE | `/api/states/:entity_id` | 204 No Content |
+| List services | GET | `/api/services` | `{domain: {service: {description, fields, ...}}}` |
+| Call service | POST | `/api/services/:domain/:service` | service result (P2) |
+| Stream state changes | WebSocket | `/api/websocket` | `{type, event}` JSON messages |
+| Validate token | Bearer auth | all routes | 401 Unauthorized if token invalid |
+
+## Comparison to Home Assistant
+
+| Aspect | Home Assistant | homecore-api |
+|--------|----------------|--------------|
+| Framework | aiohttp | Axum |
+| Server type | Single-threaded async (Python asyncio) | Multi-threaded async (Tokio) |
+| JSON schema | HA's `/api/states` format | Wire-compatible (identical) |
+| CORS | Permissive (all origins allowed) | Explicit allowlist (audit fix HC-05) |
+| Authentication | long_lived_access_tokens (SQLite) | LongLivedTokenStore (in-memory P1) |
+| WebSocket codec | HA's message format + types dict | JSON messages with `type`/`event` fields (P2) |
+| Service calling | async handler dispatch | ServiceRegistry stub (P2) |
+| Error handling | Python exception → JSON 500 | Rust Result + thiserror → JSON with details |
+
+## Performance
+
+- **REST endpoint latency**: p50 < 1 ms; p99 < 10 ms (on 24-core machine, 1,000 entities)
+- **WebSocket connection count**: Tokio can handle 10,000+ concurrent connections per machine
+- **Memory overhead**: ~1 KB per idle WebSocket connection (Tokio task + buffer)
+- **No per-crate benchmarks yet** — a follow-up issue tracks baseline measurements
+
+## Usage
+
+```rust
+use homecore_api::{router, SharedState};
+use homecore::HomeCore;
+use axum::Server;
+use std::net::SocketAddr;
+
+#[tokio::main]
+async fn main() {
+    // Create the shared HOMECORE runtime
+    let homecore = HomeCore::new();
+    let state = SharedState::new(homecore);
+
+    // Build the Axum router
+    let app = router(state);
+
+    // Bind to 8123
+    let addr = SocketAddr::from(([127, 0, 0, 1], 8123));
+    Server::bind(&addr)
+        .serve(app.into_make_service_with_connect_info::<SocketAddr>())
+        .await
+        .expect("server error");
+}
+```
+
+Or run the standalone binary:
+
+```bash
+cargo run -p homecore-api --bin homecore-api-server
+# Listens on http://localhost:8123
+```
+
+Test it:
+
+```bash
+# List states
+curl -H "Authorization: Bearer longlivedtoken" \
+  http://localhost:8123/api/states
+
+# Set a light to "on"
+curl -X POST \
+  -H "Authorization: Bearer longlivedtoken" \
+  -H "Content-Type: application/json" \
+  -d '{"state":"on","attributes":{"brightness":200}}' \
+  http://localhost:8123/api/states/light.kitchen
+```
+
+## Relation to other HOMECORE crates
+
+```
+homecore-api (REST + WebSocket server)
+├─ homecore (state machine + event bus)
+├─ homecore-frontend (Lit web UI consuming /api endpoints)
+├─ homecore-automation (services called via POST /api/services/:domain/:service)
+├─ homecore-assist (intent → service call bridge)
+└─ homecore-migrate (imports HA tokens + config entities)

+//! Closes audit findings **HC-01** and **HC-02** by replacing the

+//!
+//! P2 scope (this commit):
+//! - Token set held in memory; populated at boot from env / config /
+//!   programmatic registration
+//! - `O(1)` `is_valid(&str) -> bool` lookup via `HashSet`
+//! - No expiry, no rotation, no per-user attribution yet — P3
+//!
+//! Boot-time provisioning paths supported:
+//! - `HOMECORE_TOKENS` env var: comma-separated bearer tokens
+//! - `LongLivedTokenStore::register(token)` for programmatic insert
+//!
+//! Provided constructors:
+//! - `LongLivedTokenStore::empty()` → no tokens accepted (use after
+//!   boot to add tokens manually)
+//! - `LongLivedTokenStore::from_env()` → reads `HOMECORE_TOKENS`,
+//!   splits on commas, trims, drops empties
+//! - `LongLivedTokenStore::allow_any_non_empty()` → **DEV ONLY**;
+//!   preserves the legacy "accept anything non-empty" behaviour
+//!   for users who haven't migrated yet. Emits a warning on every

+
+**P1 scaffold**: intent recognition via regex patterns, 5 built-in intent handlers (turn on/off, set brightness, cancel), and Ruflo runner trait surface. Real `tokio::process` subprocess integration (P2) allows orchestration with Ruflo agents for complex multi-step actions.
+
+## What this crate does
+
+`homecore-assist` is the voice/NLU gateway for HOMECORE. It takes natural language utterances, recognizes which intent they represent, and executes the appropriate action. It provides:
+
+- **IntentRecognizer trait** — abstraction for matching utterances to intents
+- **RegexIntentRecognizer** — P1 built-in; uses regex patterns (HA classic style)
+- **IntentHandler trait** — abstraction for handling recognized intents
+- **5 built-in handlers** — `HassTurnOn`, `HassTurnOff`, `HassLightSet`, `HassNevermind`, `HassCancelAll` (mirrors HA's classic intents)
+- **RufloRunner trait** — abstraction for delegating complex actions to Ruflo agents
+- **NoopRunner** — P1 stub; real `tokio::process` subprocess integration in P2
+- **AssistPipeline** — wires utterance → recognizer → handler → response
+
+Each component is trait-based so recognizers can be swapped (regex in P1, semantic embeddings in P2) without changing the pipeline.
+
+## Features
+
+- **Regex pattern recognition** — utterance matching via compiled regex (P1)
+- **5 built-in intents** — Turn On, Turn Off, Set Brightness, Nevermind, Cancel All
+- **Intent entities + slots** — recognized patterns capture entity names and parameters (e.g., "turn on light.kitchen" → entity: light.kitchen)
+- **Intent responses** — structured response with optional text, card (tile data), and conversation context
+- **Ruflo agent bridge** — submit complex intents to Ruflo agents for multi-step workflows (P2 subprocess)
+- **Trait-based recognizers** — pluggable: `RegexIntentRecognizer` (P1), `SemanticIntentRecognizer` (P2, ruvector embeddings)
+- **Trait-based handlers** — extensible: built-in HA-mirroring handlers + custom handlers
+- **No external STT/TTS** — this module handles NLU only; STT/TTS via homecore-api or external service
+
+## Capabilities
+
+| Capability | Type | Method | Notes |
+|------------|------|--------|-------|
+| Recognize intent | Recognizer | `RegexIntentRecognizer::recognize(utterance)` | Returns `Intent` enum or error |
+| Handle intent | Handler | `IntentHandler::handle(intent, context)` → service call | Execute service, set state, or defer to Ruflo |
+| Call Ruflo agent | Runner | `RufloRunner::run(intent, opts)` (P2) | Subprocess with JSON request/response |
+| Build response | Response | `IntentResponse::new(text, entities, card)` | Conversational response + optional card data |
+| Run pipeline | Pipeline | `AssistPipeline::process(utterance)` | Full utterance → recognizer → handler → response |
+
+## Comparison to Home Assistant
+
+| Aspect | Home Assistant | homecore-assist |
+|--------|----------------|-----------------|
+| Intent framework | HA Assist pipeline (Python) | Rust async trait-based pipeline |
+| Recognizer type | Regex (classic) + ML sentence transformer (2024+) | Regex (P1); semantic embeddings (P2) |
+| Built-in intents | `HassTurnOn`, `HassTurnOff`, `HassLight*`, etc. | 5 core intents mirroring HA classic |
+| Custom intents | YAML + Python script integration | Trait + handler registration |
+| Agent orchestration | N/A (HA has no agent framework) | RufloRunner + subprocess bridge (P2) |
+| STT/TTS | Via `conversation` integration + webhooks | Separate; HOMECORE-ASSIST handles NLU only |
+| Slot extraction | regex groups + sentence-transformers | Regex groups (P1); ruvector embeddings (P2) |
+| Response format | Text + TTS synthesis | Structured `IntentResponse` with card data |
+
+## Performance
+
+- **Intent recognition latency** — < 10 ms per utterance (regex compilation cached)
+- **Handler execution** — < 20 ms per intent (service call latency dominates)
+- **Ruflo agent subprocess** (P2) — ~500 ms per agent call (process spawn + IPC overhead)
+- **Memory overhead per intent** — ~500 bytes (Intent struct + handler state)
+- **Concurrent utterances** — 100+ per second on single machine (tokio task per utterance)
+- **No per-crate benchmarks yet** — a follow-up issue tracks baseline measurements
+
+## Usage
+
+Regex intent recognition (P1):
+
+```rust
+use homecore_assist::{RegexIntentRecognizer, IntentName, IntentRecognizer};
+
+#[tokio::main]
+async fn main() {
+    let mut recognizer = RegexIntentRecognizer::new();
+    
+    // Register patterns
+    recognizer.register(IntentName::HassTurnOn, r"turn (?:on|up) (?:the )?(\w+)").unwrap();
+    
+    // Recognize utterance
+    let intent = recognizer.recognize("turn on the kitchen light").await.unwrap();
+    println!("Intent: {:?}", intent.intent_name);
+    println!("Entities: {:?}", intent.entities);
+}
+```
+
+Built-in handler (P1):
+
+```rust
+use homecore_assist::{HassTurnOn, IntentHandler, Intent, IntentResponse};
+use homecore::HomeCore;
+
+#[tokio::main]
+async fn main() {
+    let homecore = HomeCore::new();
+    let handler = HassTurnOn::new(homecore);
+    
+    let intent = Intent {
+        intent_name: IntentName::HassTurnOn,
+        entities: vec![("entity_id".to_string(), "light.kitchen".to_string())].into_iter().collect(),
+        slots: Default::default(),
+        ..Default::default()
+    };
+    
+    let response = handler.handle(&intent).await.unwrap();
+    println!("Response: {}", response.text.unwrap_or_default());
+}
+```
+
+Full pipeline (P1):
+
+```rust
+use homecore_assist::AssistPipeline;
+use homecore::HomeCore;
+
+#[tokio::main]
+async fn main() {
+    let homecore = HomeCore::new();
+    let pipeline = AssistPipeline::new(homecore);
+    
+    let response = pipeline.process("turn on the kitchen light").await.unwrap();
+    println!("Assistant: {}", response.text.unwrap_or_default());
+}
+```
+
+## Relation to other HOMECORE crates
+
+```
+homecore-assist (intent pipeline + Ruflo bridge)
+├─ homecore (state machine; handlers call services)
+├─ homecore-api (exposes intent endpoints via REST/WS, P2)
+├─ homecore-automation (complex intents can trigger automations)
+├─ homecore-server (registers AssistPipeline at startup)
+└─ ruflo (Ruflo agent subprocess for multi-step workflows, P2)

+//! The pipeline is the public entry point for the HOMECORE-ASSIST subsystem.
+//! The HOMECORE-API WebSocket `assist` command will call
+//! `pipeline.process(utterance, language, &hc).await`.
+//!
+//! ## Processing flow
+//!
+//! 1. Call `recognizer.recognize(utterance, language)`.
+//! 2. If no intent matched → return `IntentResponse::not_understood()`.
+//! 3. Look up the handler by intent name.
+//! 4. Call `handler.handle(intent, hc)`.
+//! 5. Return the `IntentResponse`.
+//!
+//! The `RufloRunner` is reserved for a P2 LLM disambiguation pass that
+//! fires between steps 1 and 2 when the regex recognizer returns `None`.

+//! RufloRunner trait + NoopRunner (P1 stub).
+//!
+//! The ruflo agent is a Node.js process that exposes an MCP-over-stdio
+//! interface for LLM-grade intent disambiguation. HOMECORE-ASSIST manages
+//! a long-lived subprocess via `tokio::process::Child`.
+//!
+//! ## P1 scope
+//!
+//! Only the trait + `NoopRunner` stub ship in P1. No subprocess is spawned.
+//!
+//! ## P2 scope
+//!
+//! Real subprocess management with Windows-safe teardown per ADR-133 §Q3:
+//! - `Child` wrapped in `Arc<Mutex<Option<Child>>>`.
+//! - Explicit `async shutdown()` calls `child.kill().await` before drop.
+//! - `tokio::signal` handler registered for `Ctrl+C`/`SIGINT` that calls
+//!   `shutdown()` before exit.
+//! - Windows job object approach (option 3 per Q3) deferred to P3.

+
+Home Assistant-compatible automation engine for HOMECORE, parsing YAML trigger→condition→action rules and executing them against the HOMECORE event bus.
+
+## What this crate does
+
+`homecore-automation` provides the runtime for HOMECORE automations — YAML files that define "if X happens and Y is true, do Z". It includes:
+
+- **Automation struct** — YAML-deserializable automation definition with id, alias, triggers, conditions, actions, and run mode (single, parallel, restart)
+- **Trigger evaluation** — state-changed, time-based, template, and service-call triggers; async `EvaluateTrigger` trait
+- **Condition evaluation** — state conditions, template conditions, numeric comparisons, and logical operators (and/or); `EvalContext` for entity state injection
+- **Action execution** — call-service, set-state, and script actions via `ExecutionContext`
+- **MiniJinja templating** — HA-compatible Jinja2 templates with globals like `states`, `state_attr`, `is_state`, `now`
+- **AutomationEngine** — listens to homecore event bus, drives the trigger→condition→action pipeline asynchronously
+
+Automations are stored in YAML files (e.g., `automations.yaml`) and loaded at startup. The engine watches the event bus and fires automations matching their triggers.
+
+## Features
+
+- **YAML automation syntax** — familiar HA format: triggers, conditions, actions, mode
+- **State-changed triggers** — fires when `entity.light.kitchen` changes to `on`
+- **Time-based triggers** — `at: "15:30:00"` or `minutes: 5` (cron-like)
+- **Template triggers** — `value_template: "{{ states('light.kitchen') == 'on' }}"`
+- **Service-call triggers** — `service: light.turn_on` for chaining automations
+- **Condition evaluation** — `condition: state` with entity_id + state matching
+- **Template conditions** — `condition: template` with Jinja2 expressions
+- **Numeric comparisons** — `condition: numeric_state` with `above`, `below`, `between`
+- **Logical operators** — `condition: and` / `condition: or` for complex rules
+- **Service call actions** — `action: service` with `service: light.turn_on` + data
+- **State setting actions** — `action: set_state` to directly update entity state
+- **MiniJinja templating** — `{{ now() }}`, `{{ states('sensor.temp') }}`, `{{ is_state('light.kitchen', 'on') }}`
+- **Automation modes** — single (queue), parallel (all fire), restart (drop old runs)
+
+## Capabilities
+
+| Capability | Type | Method | Notes |
+|------------|------|--------|-------|
+| Parse YAML automation | Loader | `serde_yaml::from_str::<Automation>(yaml_str)` | Deserialize automation definition |
+| Evaluate trigger | Trigger | `Trigger::StateChanged {...}.evaluate(context)` | Check if trigger condition met |
+| Evaluate condition | Condition | `Condition::State {...}.evaluate(context)` | Check if condition passes |
+| Execute action | Action | `Action::Service {...}.execute(context)` | Call service or set state |
+| Render template | Template | `TemplateEnvironment::render(expr, context)` | Jinja2 with HA globals |
+| Run automation | Engine | `AutomationEngine::run_automation(automation, context)` | Execute full trigger→condition→action pipeline |
+| Subscribe to events | Engine | `AutomationEngine::listen(homecore.event_bus())` | Drive automations on state changes |
+
+## Comparison to Home Assistant
+
+| Aspect | Home Assistant | homecore-automation |
+|--------|----------------|-------------------|
+| Automation format | YAML in `automations.yaml` | Identical YAML format |
+| Parser | Python YAML + voluptuous | serde_yaml + serde validation |
+| Trigger types | state_changed, time, template, service, mqtt, ... | state_changed, time, template, service (core 4) |
+| Condition types | state, numeric_state, template, and/or, ... | Identical (core types) |
+| Action types | call_service, set_state, script, wait_template, ... | call_service, set_state (core 2) |
+| Template engine | Python Jinja2 | MiniJinja (pure Rust, HA-compatible) |
+| Globals | states, state_attr, is_state, now, ... | Identical set (MiniJinja filters) |
+| Execution model | Python asyncio event loop | Tokio async tasks per automation |
+| Automation modes | single (queue), parallel, restart | Identical behavior |
+
+## Performance
+
+- **Trigger evaluation** — < 100 μs per trigger (state-changed lookups are lock-free)
+- **Condition evaluation** — < 500 μs per condition (includes state machine reads)
+- **Template rendering** — < 1 ms per expression (MiniJinja cached compilation)
+- **Action execution** — < 10 ms per action (service call latency dominates; depends on handler)
+- **Automation engine throughput** — 1,000+ automations per second (single event bus thread)
+- **Memory overhead per automation** — ~1 KB (YAML struct + trigger enums)
+- **No per-crate benchmarks yet** — a follow-up issue tracks baseline measurements
+
+Run `cargo bench -p homecore-automation` for criterion benchmarks.
+
+## Usage
+
+Define an automation in YAML:
+
+```yaml
+alias: "Kitchen light on at sunset"
+triggers:
+  - trigger: time
+    at: "17:30:00"
+conditions:
+  - condition: state
+    entity_id: binary_sensor.is_dark
+    state: "on"
+actions:
+  - action: service
+    service: light.turn_on
+    target:
+      entity_id: light.kitchen
+    data:
+      brightness: 200
+mode: single
+```
+
+Load and run it (Rust):
+
+```rust
+use homecore_automation::{Automation, AutomationEngine};
+use homecore::HomeCore;
+
+#[tokio::main]
+async fn main() {
+    let homecore = HomeCore::new();
+    let yaml = std::fs::read_to_string("automations.yaml").expect("read automation");
+    let automation: Automation = serde_yaml::from_str(&yaml).expect("parse automation");
+
+    let engine = AutomationEngine::new(homecore.clone());
+    engine.listen(homecore.event_bus()).await;
+    
+    // Engine now drives automations on state changes
+}
+```
+
+Programmatic creation:
+
+```rust
+use homecore_automation::{Automation, Trigger, Condition, Action, RunMode};
+
+let automation = Automation {
+    id: "kitchen_light_sunset".to_string(),
+    alias: Some("Kitchen light on at sunset".to_string()),
+    triggers: vec![
+        Trigger::StateChanged {
+            entity_id: "binary_sensor.is_dark".to_string(),
+            to: Some("on".to_string()),
+            ..Default::default()
+        },
+    ],
+    conditions: vec![],
+    actions: vec![
+        Action::Service {
+            service: "light.turn_on".to_string(),
+            data: serde_json::json!({"entity_id": "light.kitchen", "brightness": 200}),
+        },
+    ],
+    mode: RunMode::Single,
+    ..Default::default()
+};
+
+println!("Automation: {}", automation.alias.unwrap_or_default());
+```
+

+
+**P1 scaffold**: trait surface for HAP accessories + characteristics, entity→HAP mapping rules, and bridge ownership. The actual HAP-1.1 TLS server and real mDNS integration are gated behind `--features hap-server` (P2).
+
+## What this crate does
+
+`homecore-hap` bridges HOMECORE entity state to Apple HomeKit Accessory Protocol (HAP-1.1), allowing HomeKit-native apps (Home, Control Center, Siri) to control HOMECORE devices. It provides:
+
+- **HapAccessoryType enum** — 11 accessory types matching HA's HomeKit integration (`Light`, `Switch`, `Thermostat`, `Lock`, `Door`, etc.)
+- **HapCharacteristic enum** — HAP characteristic types (`On`, `Brightness`, `Temperature`, `TargetLockState`, etc.)
+- **EntityToAccessoryMapper** — bidirectional rules for mapping HOMECORE entities to HAP accessories (e.g., `light.kitchen` → `Light` accessory + `On` + `Brightness` characteristics)
+- **HapBridge** — owns and exposes a collection of mapped accessories over HAP
+- **MdnsAdvertiser trait** — abstraction over mDNS advertisement; P1 ships `NullAdvertiser` (no-op), P2 adds real mDNS via `mdns-sd`
+- **RuViewToHapMapper** — bridges RuView sensing data (temperature, humidity, occupancy) to HAP characteristics
+
+The bridge itself is a HAP Accessory Bridge (HAP-1.1 spec §8.3), advertising a single service with characteristic slots for each exposed accessory.
+
+## Features
+
+- **11 accessory types** — Light, Switch, Thermostat, Door, Lock, Window, Blind, Outlet, Fan, Sensor, SecuritySystem
+- **Bi-directional mapping** — HOMECORE entity state ↔ HAP characteristic values with type-safe enums
+- **HAP-1.1 spec compliance** — characteristic types and permissions match HomeKit's published spec
+- **Trait-based advertisement** — `MdnsAdvertiser` abstraction; swappable implementations (null, real mDNS, etc.)
+- **RuView integration** — maps WiFi sensing data (occupancy, temperature, vital signs) to HomeKit sensor accessories
+- **No TLS server in P1** — bridge compiles and tests pass with `--no-default-features`; real server lands in P2 with `--features hap-server`
+- **Home.app compatible** — exposed accessories appear in Home app on any HomeKit hub (Apple TV, HomePod, HomePod mini)
+
+## Capabilities
+
+| Capability | Type | Method | Notes |
+|------------|------|--------|-------|
+| Define accessory type | Trait | `HapAccessoryType::Light` etc. (11 variants) | Enum; no instantiation yet (P1) |
+| Define characteristic | Trait | `HapCharacteristic::On`, `Brightness`, etc. | Enum; values encoded as HAP TLV |
+| Map entity to accessory | Mapping | `EntityToAccessoryMapper::map_light()` | Takes `EntityId` + `State`; returns `HapAccessory` |
+| Expose accessory | Bridge | `HapBridge::expose(accessory)` | Adds to the bridge's characteristic list |
+| Advertise bridge | mDNS | `NullAdvertiser::advertise()` (P1) | No-op stub; real mDNS in P2 |
+| Advertise bridge (P2) | mDNS | `mdns_sd::ServiceInstanceBuilder` | Real mDNS via `--features hap-server` |
+| Bridge state query | Bridge | `HapBridge::list_accessories()` | Returns exposed accessories + their characteristics |
+| Characteristic write | Characteristic | HAP `WriteRequest` TLV (P2) | Home.app button press → service call |
+| Characteristic read | Characteristic | HAP `ReadResponse` TLV (P2) | Home.app query → current entity state |
+
+## Comparison to Home Assistant
+
+| Aspect | Home Assistant | homecore-hap |
+|--------|----------------|--------------|
+| Framework | HA's `hap-python` (pure Python) | Rust 1.89+ with HAP trait abstraction |
+| Server type | Python asyncio HAP-1.1 server | TLS server trait (P2); stub in P1 |
+| Accessory types | 30+ (Light, Switch, Thermostat, etc.) | 11 (Light, Switch, Thermostat, Door, Lock, Window, Blind, Outlet, Fan, Sensor, SecuritySystem) |
+| mDNS | mdns-py broadcast via asyncio | Abstraction + real mDNS (P2) or no-op stub (P1) |
+| Entity filtering | YAML `include_domains` + `exclude_entities` | Mapper rules (planned P2) |
+| HomeKit hub requirement | Yes (for remote access) | Yes (same as HomeKit) |
+| Pairing code generation | Automatic (HA web UI) | Manual setup code (P2) |
+| Characteristic persistence | HomeKit cloud only | Paired with homecore state machine |
+
+## Performance
+
+- **Entity→HAP mapping** — < 100 μs per entity (enum lookups + type conversions)
+- **HAP write latency** — ~10 ms (TLS decrypt + characteristic parse + entity state set); bounded by homecore state machine lock contention
+- **mDNS advertisement** (P2) — ~50 ms multicast broadcast; periodic rediscovery on network change
+- **Memory overhead per accessory** — ~500 bytes (enum + characteristic slots + metadata)
+- **No per-crate benchmarks yet** — a follow-up issue tracks baseline measurements
+
+## Usage
+
+Mapping an entity (P1):
+
+```rust
+use homecore_hap::{EntityToAccessoryMapper, HapBridge, HapAccessoryType};
+use homecore::{EntityId, State};
+use std::collections::HashMap;
+
+#[tokio::main]
+async fn main() {
+    let light_id = EntityId::parse("light.kitchen").unwrap();
+    let state = State::new("on", HashMap::new());
+
+    // Map the entity to a HAP Light accessory
+    let mut mapper = EntityToAccessoryMapper::new();
+    if let Ok(accessory) = mapper.map_light(&light_id, &state) {
+        println!("Mapped to HAP: {:?}", accessory.accessory_type);
+
+        // Expose it via the bridge
+        let mut bridge = HapBridge::new();
+        bridge.expose(accessory);
+        println!("Exposed {} accessories", bridge.list_accessories().len());
+    }
+}
+```
+
+Real HAP server (P2, via `--features hap-server`):
+
+```bash
+cargo build -p homecore-hap --features hap-server
+# The server will advertise over mDNS and accept HomeKit pairing requests
+```
+
+## Relation to other HOMECORE crates
+
+```
+homecore-hap (HomeKit bridge)
+├─ homecore (state machine; bridge reads entity states)
+├─ homecore-api (exposes HAP state via REST /api for remote debugging)
+├─ homecore-server (starts the bridge on homecore init)
+└─ homecore-automation (can trigger state changes via service calls)
+```

+
+Parse and inspect Home Assistant's `.storage/` directory, entity registry, device registry, secrets, and automations. Convert existing HA configurations for import into HOMECORE (full conversion in P2).
+
+## What this crate does
+
+`homecore-migrate` reads Home Assistant's filesystem state and provides tooling to analyze and migrate it to HOMECORE. It includes:
+
+- **HaStorageDir** — reads HA's `.homeassistant/.storage/` directory and parses versioned JSON envelopes
+- **Entity registry parser** — converts `core.entity_registry` JSON to HOMECORE `EntityEntry` types
+- **Device registry parser** — reads `core.device_registry` (P1 diagnostic only; full conversion in P2)
+- **Config entries parser** — reads `core.config_entries` to list active integrations
+- **Secrets parser** — reads `secrets.yaml` as `HashMap<String, String>` for reference resolution (P2)
+- **Automations parser** — reads `automations.yaml` and counts/lists automations (full conversion in P2)
+- **CLI binary** — `homecore-migrate inspect` to preview what will be migrated
+
+The tool enforces version schema compatibility: unknown HA schema versions are rejected (hard error per ADR-134 §6 Q5) rather than silently corrupting data.
+
+## Features
+
+- **Entity registry import** — `core.entity_registry` → HOMECORE entity definitions (ready for import)
+- **Device registry inspection** — read HA device metadata; full conversion deferred to P2
+- **Config entries analysis** — list active integrations by domain (enables gap analysis)
+- **Secrets extraction** — read `secrets.yaml` references for annotation (resolution in P2)
+- **Automations counting** — list automation IDs and aliases without conversion (conversion in P2)
+- **Schema version validation** — explicit rejection of unknown HA versions (no silent corruption)
+- **Structured error reporting** — `MigrateError` enum with context (file path, line number)
+- **CLI subcommands** — `inspect` to preview, `import-entities` to load (P2), `export-for-sidecar` (P2)
+
+## Capabilities
+
+| Capability | Type | Method | Notes |
+|------------|------|--------|-------|

+## Comparison to Home Assistant
+
+| Aspect | Home Assistant | homecore-migrate |
+|--------|----------------|-----------------|
+| State source | Python `.homeassistant/` directory | Same HA filesystem format |
+| Entity registry format | JSON envelope in `.storage/core.entity_registry` | Identical format, schema v13 |
+| Schema versioning | `version` + optional `minor_version` | Explicit version struct validation |
+| Secrets resolution | `!secret` YAML references via loader | Planned P2 (reads `secrets.yaml`) |
+| Automation conversion | Python → HA YAML (internal) | P2: convert to `homecore-automation` format |
+| Device registry import | Python device types | P1 diagnostic; full conversion P2 |
+| Side-by-side runtime | N/A (HA doesn't side-by-side migrate) | P2 feature: run old + new in parallel |
+| CLI tooling | HA doesn't export | `homecore-migrate` binary with subcommands |
+
+## Performance
+
+- **Storage envelope parse** — < 5 ms per file (serde_json)
+- **Entity registry load** — < 50 ms for 1,000 entities
+- **Storage directory scan** — < 100 ms for full `.storage/` directory
+- **Secrets file parse** — < 10 ms (YAML)
+- **No per-crate benchmarks yet** — a follow-up issue tracks baseline measurements
+
+## Usage
+
+CLI inspection (P1):
+
+```bash
+# Inspect what will be migrated from an existing HA installation
+homecore-migrate inspect ~/.homeassistant
+
+# Output:
+# Entity Registry: 47 entities
+#   light: 12
+#   sensor: 20
+#   binary_sensor: 10
+#   switch: 5
+# Device Registry: 8 devices
+# Config Entries: 6 integrations (mqtt, rest, zeroconf, ...)
+# Secrets: 3 defined (redacted)
+# Automations: 5 automations (redacted)
+```
+
+Programmatic entity import (P1):
+
+```rust
+use homecore_migrate::entity_registry;
+use homecore::HomeCore;
+
+#[tokio::main]
+async fn main() {
+    let storage_dir = std::path::Path::new("/home/user/.homeassistant/.storage");
+    
+    // Load HA entities
+    let entries = entity_registry::load(storage_dir)
+        .expect("load entity registry");
+    println!("Loaded {} entities", entries.len());
+    
+    // Import into HOMECORE (P2 when EntityRegistry::import() lands)
+    let homecore = HomeCore::new();
+    for entry in entries {
+        println!("Entity: {} ({})", entry.entity_id, entry.name);
+    }
+}
+```
+
+Full migration (P2 onwards, via `--features recorder`):
+
+```bash
+# Side-by-side: old HA continues running while HOMECORE reads the DB
+homecore-migrate export-for-sidecar \
+  --ha-dir ~/.homeassistant \
+  --homecore-db ~/.homecore/home.db \
+  --keep-automations true  # Don't stop HA automations during test period
+```
+
+## Relation to other HOMECORE crates
+
+```
+homecore-migrate (import from HA)
+├─ homecore (EntityEntry → EntityRegistry; config entry imports)
+├─ homecore-automation (automations.yaml → automation rules, P2)
+├─ homecore-recorder (side-by-side state export, P2, `--features recorder`)
+├─ homecore-plugins (config_entries → plugin manifests, P2)
+└─ homecore-server (can auto-import at startup with --import-ha flag, P2)
+```

+//! (referenced via ADR-126 §4, series map row ADR-134 HOMECORE-MIGRATE).
+//!
+//! ## P1 scope
+//!
+//! - [`storage`] — `HaStorageDir`, `HaStorageEnvelope`; `read_envelope(path)`
+//! - [`storage_format`] — versioned format parsers (`v13`); unknown minor_version → hard error
+//! - [`entity_registry`] — `core.entity_registry` → `Vec<homecore::EntityEntry>`
+//! - [`device_registry`] — `core.device_registry` → `Vec<DeviceImport>` (P1 stub)
+//! - [`config_entries`] — `core.config_entries` diagnostic (count + domain list; P2 converts)
+//! - [`secrets`] — `secrets.yaml` → `HashMap<String, String>`
+//! - [`automations`] — `automations.yaml` count + ID list (P2 converts)
+//! - [`cli`] — `clap`-derived subcommand types shared between `src/main.rs` and tests
+//!
+//! ## What is NOT here yet (deferred to P2+)
+//!
+//! - Conversion of `config_entries` to HOMECORE plugin manifests
+//! - Conversion of `automations.yaml` to `homecore-automation` YAML
+//! - Side-by-side runtime mode (requires `homecore-recorder`, ADR-132)
