docs(adr): ADR-180 — through-wall camera↔CSI hand-off demo ("Behind the Wall")

Proposed design for the HTML demo: camera-supervised CSI model infers a full
skeleton, hands off camera→RF when you walk behind a wall, and keeps inferring
the skeleton through the wall (S3 + C6 mmWave + Pi5 nexmon multistatic fusion +
AETHER re-ID). Dead-reckoning Kalman smoother (reuses pose_tracker.rs) keeps the
figure fluid through dropped CSI with bounded extrapolation → LOST, never a
phantom. Honesty mechanism: a far-side camera (cognitum-v0) provides ground
truth behind the wall so the through-wall skeleton PCK is MEASURED + published
(metric-locked, ADR-173), not claimed. Reuses ADR-079 supervision, the
multistatic fuser, the calibration crate, and the Observatory UI — new code is a
hand-off module + dead-reckoning smoother + a single-file HTML viewer.

+#
+# HONEST SCOPE (read this before assuming this gates on timing):
+#   * The `bench-compile` job is a REAL, HARD-FAILING regression gate. It runs
+#     `cargo bench --no-default-features --no-run`, which type-checks and links
+#     EVERY criterion bench in the v2/ workspace without running a single
+#     measurement. Benches are not part of `cargo test`, so they silently
+#     bit-rot when a public API they call changes — this job catches that the
+#     moment it happens. This is the part of this workflow that can fail a PR.
+#
+#   * The `bench-fast-run` job runs a small, curated subset of pure-CPU benches
+#     in criterion "quick mode" (short warm-up / measurement / 10 samples) and
+#     is INFORMATIONAL ONLY (`continue-on-error: true`). It does NOT gate on
+#     timing. Wall-clock timings on shared GitHub-hosted runners vary by
+#     2-3x run-to-run (noisy neighbours, CPU throttling, no pinned frequency),
+#     so a hard ">X ms" threshold here would flake constantly and teach
+#     everyone to ignore it. We deliberately do not pretend to do timing
+#     regression-gating we cannot deliver reliably. The numbers are surfaced in
+#     the job log + uploaded as an artifact for humans to eyeball trends.
+#
+# WHY NO criterion --baseline COMPARE GATE:
+#   criterion's `--save-baseline` / `--baseline` compare is the textbook
+#   regression mechanism, but it only produces a trustworthy verdict when the
+#   baseline and the candidate were measured on the SAME hardware under the SAME
+#   conditions. GitHub-hosted runners give neither (the baseline commit and the
+#   PR commit land on different physical machines). Committing a baseline JSON
+#   measured on one runner and comparing a different runner against it would
+#   manufacture false regressions. If/when these benches run on a dedicated,
+#   frequency-pinned self-hosted runner, a `--baseline` compare with a generous
+#   (>2x) noise floor becomes honest and can be added then. Until then,
+#   compile-verify + informational-run is the honest gate.

+# PROOF — reproduce every claim, or find the one we can't yet
+
+This project (RuView / wifi-densepose) has been publicly called "AI slop" and
+"fake." This document is the answer: **a skeptic can clone the repo, run one
+script, and have every headline claim either verified on their own machine or
+shown — explicitly — as "CLAIMED, not yet reproduced (here's exactly what it
+needs)."** Nothing below is asserted without a command you can run.
+
+```bash
+git clone https://github.com/ruvnet/RuView && cd RuView
+bash scripts/prove.sh          # core gate + the anti-slop assertion tests
+bash scripts/prove.sh --full   # also attempt the feature-gated subset
+```
+
+`prove.sh` exits 0 only if every **non-gated** claim passes. Gated claims never
+fail the run; they print the prerequisite (a GPU, a dataset, real hardware, a
+trained checkpoint) so you can reproduce them yourself.
+
+## Grading
+
+- **MEASURED** — reproduced on our hardware, with the exact command recorded, and
+  pinned by a test that *fails on the pre-fix code*. `prove.sh` re-runs these.
+- **CLAIMED** — cited from a source, or measured by the source, but not
+  reproduced in this repo's automated harness.
+- **DATA-GATED / HARDWARE-GATED** — the *code path* is real and tested, but the
+  *accuracy/throughput claim* needs data or hardware we don't ship. We never
+  fabricate the number; the code carries a typed error or a `weights_trained`/
+  provenance flag instead.
+
+## The hard gate (run on any machine with Rust + Python)
+

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

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

+
+## The open scorer
+
+The scoring engine is a pure-Rust, GPU-free binary: `aa_score_runner` in `wifi-densepose-train`. It runs the real `ruview_metrics` pose-acceptance harness on a fixed fixture and emits a cross-platform-stable SHA-256 **determinism proof**.
+
+### Reproduce the determinism hash locally
+
+```bash
+cd v2
+# Verify the committed expected hash still matches (this is the CI gate):
+cargo run -q -p wifi-densepose-train --bin aa_score_runner --no-default-features
+# → prints the witness (inputs_sha256 + proof_sha256) and "VERDICT: PASS"
+
+# See the witness row as JSON:
+cargo run -q -p wifi-densepose-train --bin aa_score_runner --no-default-features -- --json
+```
+
+### Witness chain — proof + repeatability analysis
+
+Every score is a **witness**: `inputs_sha256` (binds it to the exact inputs scored)
++ `proof_sha256` (cross-platform-stable hash of the quantised score) + `harness_version`.
+Witnesses are recorded in an **append-only, hash-chained ledger** (each row references
+the previous row's hash), so a silent edit to any past row breaks the chain.
+
+```bash
+# Repeatability: run the scorer K times, confirm ONE identical proof hash:
+cd v2
+cargo run -q -p wifi-densepose-train --bin aa_score_runner --no-default-features -- --repeat 16
+# → {"repeatability":{"runs":16,"unique_proof_hashes":1,"repeatable":true,...}}
+
+# Real model scoring (score predictions against an eval split):
+cargo run -q -p wifi-densepose-train --bin aa_score_runner --no-default-features -- \
+  --split ../aether-arena/fixtures/smoke_split.json \
+  --pred  ../aether-arena/fixtures/smoke_pred.json --json
+
+# Verify the witness ledger chain is intact (tamper-evident):
+cd ../aether-arena/ledger && python3 ledger_tools.py verify
+# → "OK: N rows, chain intact"   (edit any row and it reports the broken link)
+```
+
+The expected hash is committed at [`fixtures/expected_score.sha256`](fixtures/expected_score.sha256). Same harness version + same fixture → same hash on glibc / MSVC / Apple. If your local run prints `VERDICT: PASS`, you have reproduced the scorer.
+
+### What happens if the scoring maths changes
+
+Any edit to `ruview_metrics.rs`, `ablation.rs`, or `aa_score_runner.rs` moves the hash and **fails the CI gate** (`.github/workflows/aether-arena-harness.yml`) until the maintainer regenerates and reviews:
+
+```bash
+cargo run -p wifi-densepose-train --bin aa_score_runner --no-default-features -- --generate-hash \
+  > aether-arena/fixtures/expected_score.sha256
+```
+
+So a scorer change is always a reviewed, public diff — never silent. That's `harness_version` pinning + `determinism_gate` in action (ADR-149 §2.4–§2.5).
+
+## The five-step acceptance test (v0 launch gate)
+
+A stranger must be able to:
+
+1. **Submit** a model (artifact + `schema/aa-submission.toml`) with no insider help.
+2. **Get a deterministic score** — same model + same `harness_version` → same numbers.
+3. **See the signed row** appended to the public results ledger.
+4. **Rerun the scorer locally** on the public smoke split and reproduce the logic (the command above).
+5. **Understand why the rank is fair** — private split, open scorer, pinned version, proof hash — from these docs alone.
+
+If any step fails, v0 is not ready.
+
+## Current status
+
+- ✅ Step 4 (rerun the open scorer locally, reproduce the hash) — **works today** via `aa_score_runner`.
+- ✅ CI harness gate runs the scorer on every PR.
+- ⏳ Steps 1–3, 5 (HF Space submission flow + signed ledger) — in progress; require the HF Space deploy (needs an HF token / maintainer authorization).

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

+Each row is hash-chained to the previous one: ``row_hash = sha256(canonical_row

+# AetherArena ("AA") — The Official Spatial-Intelligence Benchmark
+
+> Public leaderboard. Private evaluation split. Open scorer. Signed results.
+
+The field's standard yardstick for camera-free **spatial intelligence** (pose, presence,
+occupancy, tracking, vitals) from RF/WiFi and, over time, mmWave / UWB / multimodal.
+
+- **Project-agnostic** — any team, framework, or modality enters; RuView donated the seed
+  scorer and is scored like everyone else.
+- **Benchmark-first** — the board starts empty; every row is a real scoring-pipeline
+  **witness** (`inputs_sha256` + `proof_sha256` + `harness_version`) in an append-only,
+  hash-chained, tamper-evident ledger.
+- **Reproducible** — the scorer is open; reproduce any proof hash + repeatability locally.
+
+Spec: [ADR-149](https://github.com/ruvnet/RuView/blob/main/docs/adr/ADR-149-public-community-leaderboard-huggingface.md).
+Source + open scorer: https://github.com/ruvnet/RuView/tree/main/aether-arena
+
+Non-commercial (CC BY-NC 4.0): the v0 eval split derives from MM-Fi (CC BY-NC); AA is operated non-commercially.

+ABOUT = """
+**AetherArena** is the official, project-agnostic **Spatial-Intelligence Benchmark** —
+camera-free pose, presence, occupancy, tracking, and vitals from RF/WiFi (and, over
+time, mmWave / UWB / radar / multimodal). It is **not** a single-vendor board: any
+team, framework, or modality enters, and every entrant — including the RuView baseline
+that donated the seed scorer — is scored by the identical, open, pinned harness.
+
+The scorer reuses RuView's released `wifi-densepose-train` acceptance harness
+(`ruview_metrics` + ablation). You submit a **model, not predictions**; it is scored
+against a **private** MM-Fi held-out split; one **witness** row (inputs hash + proof
+hash + harness version) is appended to a **hash-chained, tamper-evident ledger**.
+
+**For industry:** a vendor-neutral, auditable way to compare RF-sensing models on equal
+footing — the same standardized splits, the same metric definition, the same signed,
+reproducible ledger. No more "trust our number on our split." Vendors, labs, and startups
+all submit through one pipeline and are scored identically.
+
+**Generalization Track (roadmap):** the headline isn't a single in-domain number — it's a
+battery of honest tracks: MM-Fi `random_split` (in-domain), `cross_subject` (unseen people),
+cross-room, cross-device, and confidence-calibration (ECE). Cross-subject is the real
+deployment frontier and is treated as the flagship hard benchmark.
+
+Spec: ADR-149. v0 ranks **pose, presence, edge-latency, determinism**. Tracking &
+vitals activate when their ground truth lands; **privacy-leakage** is gated until the
+membership-inference attacker ships. Source + the open scorer:
+https://github.com/ruvnet/RuView/tree/main/aether-arena
+"""
+
+SUBMIT = """
+### Submit a model
+
+1. Write a manifest — [`schema/aa-submission.toml`](https://github.com/ruvnet/RuView/blob/main/aether-arena/schema/aa-submission.toml):
+   declare your model ref, category, the ADR-145 feature set (F0 CSI … F3 BFLD), and the tensor I/O contract.
+2. Provide your model artifact (`.safetensors` / `.rvf` / LoRA adapter).
+3. It moves through `submitted → validated → quarantined → smoke_scored → full_scored → published`,
+   scored in a no-network, read-only sandbox against the private split.
+4. Your signed witness row appears on the leaderboard.
+
+**You submit a model, never predictions** — predictions on data you hold prove nothing.
+"""
+
+VERIFY = """
+### Verify it's fair (you don't have to trust us)
+
+The scorer is open and reproducible. Reproduce the determinism proof + repeatability locally:
+
+```bash
+git clone https://github.com/ruvnet/RuView && cd RuView/v2
+# determinism gate (same as CI):
+cargo run -q -p wifi-densepose-train --bin aa_score_runner --no-default-features
+# repeatability — N runs, one identical proof hash:
+cargo run -q -p wifi-densepose-train --bin aa_score_runner --no-default-features -- --repeat 16
+# verify the append-only witness ledger chain:
+cd ../aether-arena/ledger && python3 ledger_tools.py verify
+```
+
+A stranger must be able to: submit → get a deterministic score → see the signed row →
+rerun the scorer locally → understand why the rank is fair. That is the launch gate (ADR-149 §7).

+# Edge-Latency Benchmark Results — ADR-163
+
+Converting **CLAIMED** edge latency budgets into **MEASURED-on-host** numbers,
+closing the measurement debt flagged by Milestones 5/6 (ADR-159 / ADR-160).
+Benches + docs only — **no production-code behavior changed**.
+
+## The honest caveat, up front (read before citing any number)
+
+Two distinct gaps separate every number below from the figure it is converting:
+
+1. **Host ≠ ESP32.** The wasm-edge skill modules document budgets *"on ESP32-S3
+   WASM3"* (e.g. `exo_time_crystal`: "H (<10 ms)"). These benches run **native
+   x86_64 on a development laptop**, not the Xtensa/WASM3 target. A native host
+   median is an **upper bound on the algorithm's work**, not the ESP32 number.
+   WASM3 interpretation on a ~240 MHz Xtensa core is typically 1–2 orders of
+   magnitude slower than native `-O` host code, so a host median far under the
+   budget **does NOT prove the ESP32 meets it.** *The ESP32 figure is NOT
+   reproduced here — it needs hardware.*
+
+2. **Bench ≠ the doc-claimed measurement.** For the cogs, the manifest cites a
+   **cold-start** number (`cold_start_ms_avg`, weight-load included); these
+   benches measure **steady-state** per-frame `infer` (warm, weights resident).
+   Different measurements; we report both, labelled.
+
+Grades (per `benchmarks/wiflow-std/RESULTS.md` / ADR-152 vocabulary):
+- **MEASURED-on-host** — reproduced in this repo on the machine below, exact
+  command recorded. NOT the ESP32 / NOT the cold-start figure.
+- **CLAIMED (ESP32)** — the doc budget; UNMEASURED on hardware here.
+
+## Machine
+
+| | |
+|---|---|
+| Host | `ruvzen` (Windows 11, this dev box) |
+| CPU | Intel Core Ultra 9 285H |
+| Toolchain | `cargo 1.91.1`, `--release` (opt-level per crate profile) |
+| Bench harness | criterion 0.5 (`time: [low **median** high]` reported below) |
+| Date | 2026-06-12 |
+
+Run-to-run spread on this box is non-trivial (criterion's low/high bracket the
+median by a few %); the medians below are single-session captures with the smoke
+settings `--warm-up-time 1 --measurement-time 2` (wasm-edge) / `3` (cogs). Re-run
+for your own machine — the absolute numbers are host-specific.
+
+---
+
+## T1 — wasm-edge `process_frame` hot paths (ADR-160 deferred item → DONE host)
+
+The crate is **excluded from the v2 workspace**; bench from the crate dir.
+
+```bash
+cd v2/crates/wifi-densepose-wasm-edge
+cargo bench --features std -- --warm-up-time 1 --measurement-time 2
+# med_seizure_detect is medical-experimental-gated:
+cargo bench --features std,medical-experimental -- --warm-up-time 1 --measurement-time 2 med_seizure
+```
+
+| Hot path (M6-audit-named) | Bench id | Host median | Grade | Doc budget (CLAIMED, ESP32) |
+|---|---|---|---|---|
+| `exo_time_crystal` 256-pt × 128-lag autocorrelation (full buffer) | `exo_time_crystal::process_frame[autocorr_256x128]` | **17.3 µs** | MEASURED-on-host | "H (<10 ms) on ESP32-S3 WASM3" — **NOT reproduced here (needs hardware)** |
+| `exo_ghost_hunter` empty-room periodicity + hidden-breathing | `exo_ghost_hunter::process_frame[empty_room_periodicity]` | **1.44 µs** | MEASURED-on-host | research/exotic; no firm ESP32 figure — host proxy only |
+| `sec_weapon_detect` per-subcarrier Welford (MAX_SC=32) | `sec_weapon_detect::process_frame[per_sc_welford]` | **0.42 µs** (420 ns) | MEASURED-on-host | research-grade; calibration-gated — host proxy only |
+| `med_seizure_detect` clonic-phase rhythm path (steady-state frame) | `med_seizure_detect::process_frame[clonic_rhythm]` | **0.10 µs** (105 ns) | MEASURED-on-host (feature-gated) | doc budget "S (<5 ms) on ESP32"; **NOT reproduced here** |
+
+Reading these honestly:
+
+- `exo_time_crystal` at **17.3 µs host** is the only one whose host cost is even
+  in the same *thousandths* of its 10 ms ESP32 budget — it does the most work
+  (~32K MACs/frame). 17.3 µs native says the algorithm is cheap; it says
+  **nothing** about whether WASM3-on-Xtensa lands under 10 ms. A naïve
+  host→ESP32 extrapolation (assume 100× interpreter+clock penalty) would put it
+  near ~1.7 ms, comfortably under — **but that is an extrapolation, not a
+  measurement**, and is recorded here only to show the host number is not
+  obviously in tension with the budget. ESP32 figure: **UNMEASURED**.
+- `med_seizure_detect`'s 105 ns is the **steady-state** per-frame cost; the
+  expensive clonic autocorrelation only fires when the state machine is in the
+  clonic phase, so this is a lower-bound on the heavy path, not the worst case.
+  It is still a real, committed host datapoint.
+- The pre-existing `tests/budget_compliance.rs` already asserts the L/S/H
+  wall-clock tiers (25 passing tests); these criterion benches add the
+  regression-grade, reproducible median that ADR-160 deferred.
+
+---
+
+## T2 — cog steady-state inference latency (ADR-159/160 deferred item → DONE)
+
+Cog crates are normal workspace members; bench from `v2/`. Real weights
+(`count_v1.safetensors` / `pose_v1.safetensors`) ship in-repo under each cog's
+`cog/artifacts/`, so the bench measures the **real Candle CPU forward**, not the
+stub (the bench `assert!`s `backend().starts_with("candle-")`).
+
+```bash
+cd v2
+cargo bench -p cog-person-count  --no-default-features --bench infer_bench -- --warm-up-time 1 --measurement-time 3
+cargo bench -p cog-pose-estimation --no-default-features --bench infer_bench -- --warm-up-time 1 --measurement-time 3
+```
+
+| Cog | Bench id | Host median (steady-state infer, CPU) | Grade | Manifest cold-start (CLAIMED, different measurement + machine) |
+|---|---|---|---|---|
+| cog-person-count | `cog_person_count::infer[cpu_real_weights_steady_state]` | **305 µs** (idle box) | MEASURED-on-host | — (person-count manifest carries comparable provenance) |
+| cog-pose-estimation | `cog_pose_estimation::infer[cpu_real_weights_steady_state]` | **305 µs** (idle box) | MEASURED-on-host | `cold_start_ms_avg: 5.4` (30 invocations, **ruvultra/RTX 5080 host**, candle 0.9 cpu) — **cold-start, NOT steady-state; NOT this machine** |
+
+> Spread caveat (observed, honest): both medians above were captured with the box
+> otherwise idle. A re-run of the validate-form command *while a second cargo job
+> was loading the same cores* gave 385 µs (person-count) / 973 µs (pose) —
+> the criterion low/high bracket widens to ~0.34–1.18 ms under contention. The
+> 305 µs figures are the idle-box datapoints; the absolute number is host- and
+> load-dependent (the ~10× pose swing is core contention, not a code change).
+
+Reading these honestly:
+
+- **Steady-state ≠ cold-start.** The pose manifest's `5.4 ms` folds in one-time
+  weight load / mmap / first-forward allocation. This bench warms the engine
+  first and times only the recurring per-frame forward, on a *different
+  machine*. The two numbers are not comparable and we do not claim this bench
+  reproduces the 5.4 ms manifest figure.
+- Both cogs share the same conv encoder; person-count adds a count head +
+  confidence head, pose adds a 256-wide MLP head. The host steady-state cost is
+  dominated by the three dilated Conv1d layers (56→64→128→128) shared by both —
+  which is why both land at ~305 µs.
+- **Empirical confirmation of the steady-state/cold-start gap:** pose
+  steady-state (305 µs host) is ~18× *under* the manifest's 5.4 ms cold-start.
+  Even accounting for the different machine, this is the expected shape — the
+  bulk of cold-start is one-time setup, not the forward pass — and it is exactly
+  why conflating the two would be dishonest.
+
+---
+
+## Status vs the deferred items
+
+| Deferred item | Was | Now |
+|---|---|---|
+| ADR-160 "Criterion benches for `process_frame` budget claims" | ACCEPTED-FUTURE | **DONE (host)**; ESP32-on-hardware still **PENDING** (needs the wasm32 target + a flashed ESP32-S3) |
+| ADR-159/160 cog inference latency (`cold_start_ms_avg` uncommitted-benched) | CLAIMED | **MEASURED-on-host (steady-state)**; cold-start-on-ruvultra remains the manifest's separate claim |
+
+Nothing here changes runtime behavior — these are benches + this results file
+only. No crate needs republishing.

+
+### Caveats on individual results
+
+† **exo_time_crystal — honest discriminative limit.** A *pure* periodic signal
+already has autocorrelation peaks at lag L **and** 2L (natural harmonics), so this
+"period-doubling" detector cannot separate a true period-2 sub-harmonic from a
+plain periodic signal — an earlier plant using a clean sine produced a *false
+positive* (recorded during development). The construct it **can** discriminate
+with known ground truth is **periodic-coordination vs aperiodic** (noise/flat),
+which is what is measured (1.000). The original "sub-harmonic vs clean period"
+claim is **NOT** validatable with this algorithm.
+
+‡ **spt_spiking_tracker — plant must be sparse.** With weights init'd home=1.0 /
+cross=0.25, firing all 8 inputs in a zone (8×0.25=2.0 > threshold 1.0) overdrives
+*every* output neuron and the tracker collapses to zone 0 (measured 1/4 during
+development). Firing only 2 inputs (home 2.0 fires, cross 0.5 silent) yields clean
+4/4 zone localization. The validatable claim is *single-zone* localization.
+
+§ **lrn_dtw_gesture_learn — enrollment validated; replay-match NOT.** The
+deterministic, constructible part (stillness → 3 identical rehearsals → a template
+is enrolled) is MEASURED. The DTW *replay match* (731) did **not** fire on the
+identical replay in this run (`match_same=false`) — replay-recognition accuracy is
+**reported, not asserted**, and is not claimed as validated.
+
+¶ **sig_sparse_recovery — trigger validated; recovery accuracy is NEGATIVE.**
+The dropout-detection + ISTA-recovery *trigger* pipeline fires correctly on >10%
+planted nulls (asserted). But the **measured recovery accuracy is NOT a win**:
+recovered RMSE **1.0045** vs unrecovered-null RMSE **0.9830** (**−2.2%**, i.e.
+slightly *worse* than leaving the nulls at zero) on a neighbor-correlated signal.
+The tridiagonal correlation model's fixed point does not equal the planted truth.
+**The recovery's reconstruction quality is therefore NOT validated as effective on
+synthetic data** — only its detection/trigger path is. Reported honestly; no
+positive number claimed.
+
+---
+
+## DATA-GATED — NOT validatable on synthetic data
+
+Planting a "seizure-like" / "weapon-like" / "happy-like" synthetic signal and
+claiming the detector "works" validates **nothing real** and is exactly the
+AI-slop this project fights. These skills run real DSP (per ADR-160, 0 stubs) and
+keep their ADR-160 disclaimers, but get **no accuracy number** here. Each needs
+the specific real, labelled data listed:
+
+| Skill | Why not constructible on synthetic | Real data required |
+|-------|------------------------------------|--------------------|
+| `med_seizure_detect` | "seizure-like" motion is not a seizure; no ground-truth signature exists synthetically | Clinical EEG-/video-labelled tonic-clonic seizure CSI from instrumented patients |
+| `med_sleep_apnea` | a planted breathing-pause is not clinical apnea (AHI scoring, hypopnea, desaturation) | Polysomnography-labelled (PSG) overnight CSI with scored apnea/hypopnea events |
+| `med_cardiac_arrhythmia` | a synthetic HR sequence cannot encode true arrhythmia morphology | ECG-labelled CSI (AFib/PVC/etc.) from clinical monitoring |
+| `med_respiratory_distress` | distress is a clinical gestalt, not a plantable rate | Clinician-labelled respiratory-distress CSI episodes |
+| `med_gait_analysis` | clinical gait metrics need a reference motion-capture standard | Mocap-/force-plate-labelled gait CSI |
+| `sec_weapon_detect` | a high variance ratio is RF reflectivity, **not** weapon discrimination (ADR-160 §A3 already renamed the event to `HIGH_METAL_REFLECTIVITY`) | Labelled metal-object-vs-no-object CSI with controlled object classes |
+| `exo_emotion_detect` | affect is not recoverable from a planted heuristic; outputs are proxies (ADR-160 §A2) | Validated affect-labelled CSI (self-report / physiological ground truth) |
+| `exo_happiness_score` | "happiness" is a gait-energy proxy, not a measured affect (ADR-160 §A2) | Validated affect/valence-labelled CSI |
+| `exo_dream_stage` | sleep staging needs PSG reference (EEG/EOG/EMG) | PSG-staged overnight CSI |
+| `exo_gesture_language` | coarse gesture clusters ≠ true sign language (ADR-160 §A4) | Labelled ASL letter/word CSI dataset |
+
+> The above are **not failures** — they are the honest boundary. A smaller set of
+> genuinely-measured skills plus this explicit gated list is the deliverable, per
+> the prove-everything directive.
+
+---
+
+## Skills not in either list
+
+The remaining edge skills (smart-building / retail / industrial occupancy-style,
+the other `sig_*`/`lrn_*`/`spt_*`/`tmp_*`/`qnt_*`/`aut_*`/`ais_*` algorithm-named
+modules) are **wired and exercised live** in the unified pipeline integration test
+(`tests/pipeline_all.rs`, all 59 default / 64 medical skills run without panic over
+300 synthetic frames) but were **not** given an individual planted-ground-truth
+accuracy number here. They are honest REAL-DSP modules (ADR-160) whose physical
+observable could be planted with more harness work; that is deferred, not claimed.

+# WiFlow-STD (DY2434) Benchmark Results — ADR-152 §2.2
+
+Upstream: <https://github.com/DY2434/WiFlow-WiFi-Pose-Estimation-with-Spatio-Temporal-Decoupling>
+pinned at `06899d29` (2026-04-05), Apache-2.0. Dataset: Kaggle `kaka2434/wiflow-dataset`
+(12.8 GB archive → 15.5 GB extracted; 360,000 windows of 540×20 CSI + 15-keypoint 2D labels).
+
+Published claims (README "Setting 1"): PCK@20 97.25%, PCK@30 98.63%, PCK@40 99.16%,
+PCK@50 99.48%, MPJPE 0.007 m, 2.23M params, 0.07 GFLOPs.
+
+## Measurement (a): their model on their data
+
+### Artifact verification (MEASURED, 2026-06-10, this repo `eval_repro.py`)
+
+| Check | Result |
+|---|---|
+| Parameter count | **2,225,042 (2.23M) — matches claim** |
+| FLOPs (torch profiler, batch 1) | ~0.055 GFLOPs — consistent with 0.07B claim |
+| CPU latency (Windows box, torch 2.12 CPU) | 13.2 ms/window @ batch 1 (76/s); 2.48 ms/sample @ batch 64 (403/s) |
+| Checkpoint load | `weights_only=True` (no pickle code execution) |
+
+### Released checkpoint does NOT reproduce the claims — REFUTED as shipped
+
+Running the released `best_pose_model.pth` through the released code on the released
+dataset with the released split procedure (seed-42 file-level 70/15/15; 54,000 test
+samples) yields:
+
+| Metric | Published | Measured (shipped checkpoint) |
+|---|---|---|
+| PCK@20 | 97.25% | **0.08%** |
+| PCK@30 | 98.63% | 0.78% |
+| PCK@40 | 99.16% | 5.53% |
+| PCK@50 | 99.48% | 15.42% |
+| MPJPE | 0.007 | **NaN** (dataset contains NaN CSI windows) |
+
+Raw output: `results/repro_a.json`.
+
+Diagnostics (on 2,000 NaN-free windows from the first files of the dataset, i.e.
+mostly would-be *training* data — so this is not a split mismatch):
+
+- Predictions correlate with targets (Pearson r ≈ 0.76) — the checkpoint is a trained
+  model, but in a **different keypoint normalization/order** than the released data.
+- Best-case post-hoc global per-axis affine correction: PCK@20 ≈ 20%.
+- Best-case per-keypoint affine correction (15×2 fitted transforms — generous
+  cheating): PCK@20 ≈ 72%, still far below 97.25%.
+- Pred↔target keypoint correspondence matrix is degenerate (multiple predicted
+  keypoints best-match the same target joint) — keypoint convention mismatch.
+
+### Reproducibility defects in the released artifacts
+
+1. `models/__init__.py` imports `TemporalConvNet`, which `models/tcn.py` does not
+   define — **the published code does not import/run as-is**.
+2. The released root checkpoint uses pre-rename module names (`att.*`, `final_conv.*`)
+   vs the published code (`attention.*`, `decoder.*`) — same shapes/param count, but
+   confirms the checkpoint predates the published code.
+3. The second shipped checkpoint (`cross_dataset_test/WiFlow/best_pose_model.pth`) is
+   a **different architecture** (342-channel input = MM-Fi layout, 3 TCN layers,
+   3-channel/3D decoder) — not usable on their own dataset.
+4. `run.py` ignores `--data_dir` and hardcodes `../preprocessed_csi_data`.
+5. The released dataset's final 13 files (indices 487–499; 9,072 windows, 2.52%)
+   are corrupted: NaN values plus garbage amplitudes up to 3.4e38 (float32 max) in
+   data that is otherwise [0,1]-normalized. Upstream code has no NaN/inf handling;
+   training as published on this download diverges — the first corrupted batch
+   overflows fp16 autocast and permanently poisons BatchNorm running statistics
+   (GradScaler step-skipping does not protect BN). The authors' training curves
+   show normal convergence, so their local data evidently differed from the
+   Kaggle upload. Window masks: `results/nan_windows_mask.npy`,
+   `results/big_windows_mask.npy`.
+
+### Reproducing the corruption masks
+
+The two mask files (9,070 NaN/Inf windows, 9,072 with |amplitude| > 1.5;
+union 9,072, all in dataset files 487–499) are **committed ground truth**
+(gitignore-negated, ~352 KB each). They can only be regenerated from a
+**pristine** Kaggle download: `remote/clean_v2.py` repairs the dataset by
+zeroing the corrupted windows in place, after which the corruption evidence
+is gone and a rescan returns all-False. `generate_corruption_masks.py`
+re-derives them (chunked scan, criteria: any non-finite value OR
+max |finite| > 1.5 per 540×20 window) and refuses to write all-False masks,
+which indicate a cleaned copy. Verified 2026-06-11: a regeneration from the
+local pristine download is bit-identical to the committed masks.
+
+### Retraining result (MEASURED, 2026-06-10): claims APPROXIMATELY REPRODUCED
+
+Since the shipped checkpoint is unusable, measurement (a) fell back to retraining
+with upstream code + defaults (seed 42, batch 64, early-stopped at epoch 41 of 50,
+best epoch 36, ~75 s/epoch) on ruvultra (RTX 5080). Deviations, all forced and
+documented: one-line fix for defect (1); torch 2.x+cu128 instead of pinned 2.3.1
+(Blackwell sm_120 unsupported); the 9,072 corrupted windows (defect 5) zeroed
+entirely — without this the published pipeline produces NaN from epoch 1 (observed).
+Scripts mirrored in `remote/`; raw metrics in `results/eval_retrained.json`.
+
+| Metric | Published | Retrained (full test, 54,000) | Retrained (corruption-free, 52,560) |
+|---|---|---|---|
+| PCK@20 | 97.25% | **96.09%** | **96.61%** |
+| PCK@30 | 98.63% | 97.89% | 98.23% |
+| PCK@40 | 99.16% | 98.58% | 98.79% |
+| PCK@50 | 99.48% | 98.99% | 99.11% |
+| MPJPE | 0.007 | 0.0098 | 0.0094 |
+
+Within ~0.6–1.2 PCK points of every published figure (single run, corrupted train
+windows zeroed, different torch/GPU). **Verdict: the accuracy claims are credible
+and approximately reproducible — but only after repairing the released dataset and
+code.** Val best: PCK@20 96.99%, MPJPE 0.0086 (epoch 36).
+
+One more defect found during the run:
+
+6. `train.py` calls `plot_training_history`, which is not defined anywhere — the
+   built-in post-training test evaluation is unreachable as published (crashes
+   with NameError after training completes).
+
+## ADR-152 §2.2 citation rule
+
+Evidence grade for the WiFlow-STD accuracy claims after measurement (a):
+**MEASURED-EQUIVALENT (96.1–96.6% PCK@20 reproduced by retraining; shipped
+checkpoint REFUTED; dataset/code require repairs)**. RuView docs may cite
+"~96% PCK@20 (our reproduction)" — still **not comparable** to our 17-keypoint
+ESP32 numbers (different hardware, 5 subjects, in-domain random split,
+15 keypoints).
+
+## Edge optimization (measured)
+
+ADR-152 "optimize beyond SOTA" track, 2026-06-10, this Windows box (Windows 11,
+16 torch threads, torch 2.12.0+cpu, onnxruntime 1.26.0). Subject: the retrained
+checkpoint `results/retrained_best_pose_model.pth` (2,225,042 fp32 params).
+Scripts: `quantize_bench.py`, `onnx_bench.py`, `eval_ort_accuracy.py`.
+Raw numbers: `results/edge_optimization.json`.
+
+Accuracy is on a **10,000-window seed-42 random subset** of the corruption-free
+test split (same seed-42 file-level 70/15/15 split as `eval_repro.py`; 54,000
+test windows, 1,440 corrupted excluded via `results/nan_windows_mask.npy` |
+`results/big_windows_mask.npy`, leaving 52,560; subset drawn with
+`np.random.default_rng(42)`). The fp32 subset PCK@20 (96.68%) matches the full
+clean-test figure (96.61%), so the subset is representative.
+
+Latency is CPU ms/window, median of repeated runs, 3 interleaved repetitions
+per variant (medians below; run-to-run spread on this box is large, roughly
+±20-40% at batch 1 — reps are in the JSON).
+
+| Variant | Disk size | Batch 1 (ms/win) | Batch 64 (ms/win) | PCK@20 | PCK@50 | MPJPE |
+|---|---|---|---|---|---|---|
+| torch fp32 (baseline) | 9.07 MB | 11.0 | 2.27 | 96.68% | 99.15% | 0.00936 |
+| torch fp16 (`.half()`) | **4.58 MB** | 24.3 | 2.42 | 96.68% | 99.15% | 0.00946 |
+| torch int8 dynamic | 9.07 MB (unchanged) | 15.6 | 2.06 | 96.68% (identical) | 99.15% | 0.00936 |
+| ONNX fp32 (onnxruntime) | 8.97 MB | **3.2** | **2.0** | 96.68% | 99.15% | 0.00936 |
+| ONNX int8 (ORT dynamic, supplementary) | **2.44 MB** | 6.5 | 5.8 | 96.52% | 99.15% | 0.01108 |
+
+Findings:
+
+- **torch dynamic INT8 quantizes nothing on this model.** The architecture has
+  **zero `nn.Linear` layers** — it is entirely Conv1d (21) + Conv2d (22) +
+  BatchNorm. `torch.ao.quantization.quantize_dynamic` (requested over
+  `{Linear, Conv1d, Conv2d}`) converted **0 modules / 0.0% of params**: dynamic
+  quantization only has kernels for Linear/RNN-family modules and silently
+  skips convolutions. The "int8" model is bit-identical to fp32 (same outputs,
+  same 9.07 MB). Conv quantization would require static (PTQ) quantization
+  with calibration — out of scope here; the ORT dynamic path below is the
+  honest int8 datapoint.
+- **fp16 halves size for free accuracy-wise** (PCK@20 −0.005 pt, MPJPE
+  +0.0001) but is *slower* on CPU at batch 1 (~2.2×) — torch CPU fp16 conv
+  kernels are emulated. fp16 is a storage/transport format here, not a CPU
+  runtime win.
+- **ONNX Runtime is the real batch-1 latency win: ~3.4× faster than torch**
+  (3.2 vs 11.0 ms/window) at identical accuracy (parity 2.4e-7).
+
+### Verdict on the paper's "~2.2 MB int8" claim
+
+**Plausible but not free, and unreachable by the obvious PyTorch route.**
+2,225,042 params × 1 byte ≈ 2.2 MB assumes *every* parameter quantizes.
+PyTorch dynamic quantization — the one-liner most readers would reach for —
+yields **9.07 MB (0% quantized)** because the model has no Linear layers.
+ONNX Runtime dynamic quantization, which does have int8 conv weight support,
+gets **2.44 MB** (close to the claim; the overhead is BatchNorm params/buffers
+and quantization scales kept in fp32) at a measurable accuracy cost:
+PCK@20 96.68 → 96.52% (−0.16 pt) and MPJPE 0.00936 → 0.01108 (+18%), and
+~2× slower inference than ONNX fp32 (ConvInteger kernels). The paper does not
+state a method or an int8 accuracy; treat "2.2 MB" as a weight-arithmetic
+estimate, achievable in practice only via conv-capable quantization toolchains
+and with a small accuracy penalty.
+
+### ONNX export status
+
+**Works.** Exported via the TorchScript exporter (`dynamo=False`), opset 17,
+with a dynamic batch axis — `results/retrained_fp32_dynamic.onnx` (8.97 MB),
+verified to run at batch 1/2/64. The axial attention's
+`view(N*W, C, H)` reshape traced correctly (sizes recorded as graph ops, not
+baked constants). The dynamo exporter also captures the graph but crashed on
+this box writing a ✅ to a cp1252 console (cosmetic Windows encoding issue, not
+a model blocker). Parity vs torch on the stored fixture
+(`results/parity_fixture.npz`, batch 2, seed 42): **max abs diff 2.4e-7 —
+PASS** (< 1e-4). ORT-quantized int8 model: `results/retrained_int8_ort_dynamic.onnx`.
+
+### Static PTQ (calibrated) — follow-up
+
+Follow-up to the dynamic-int8 row above (2026-06-10, same box, onnxruntime
+1.26.0): ONNX Runtime **static** post-training quantization
+(`quantize_static`, QDQ format, per-channel int8 weights + int8 activations)
+of the same fp32 export, calibrated on **corruption-free TRAINING-split
+windows only** (seed-42 file-level split, same masks; 1,000 windows for
+MinMax, 512 for the histogram calibrators; never test windows). Scopes:
+"conv-only" (`op_types_to_quantize=["Conv"]` — the attention path exports as
+Einsum/Softmax, which ORT never quantizes anyway, so "all-ops" additionally
+quantizes the elementwise Mul/Sigmoid/Add/AveragePool glue). Accuracy on the
+identical 10k-window seed-42 corruption-free test subset; latency median of
+3 interleaved reps (fp32/dynamic re-benched in-session as references).
+Script: `static_ptq_bench.py`; raw: `results/edge_optimization.json`
+(`onnx_static_ptq`).
+
+| Variant | Disk size | Batch 1 (ms/win) | Batch 64 (ms/win) | PCK@20 | PCK@50 | MPJPE |
+|---|---|---|---|---|---|---|
+| ONNX fp32 (reference) | 8.97 MB | 2.5 | 1.9 | 96.68% | 99.15% | 0.00936 |
+| ORT dynamic int8 (baseline) | **2.44 MB** | 5.7 | 4.6 | 96.52% | 99.15% | 0.01108 |
+| static QDQ **Percentile(99.99) conv-only** | 2.53 MB | 5.3 | 4.7 | 96.61% | 99.16% | **0.01031** |
+| static QDQ MinMax conv-only | 2.53 MB | 5.2 | 3.3 | **96.63%** | 99.19% | 0.01084 |
+| static QDQ Entropy conv-only | 2.53 MB | 5.2 | 3.1 | 96.60% | 99.19% | 0.01078 |
+| static QDQ MinMax all-ops | 2.60 MB | 6.5 | 3.9 | 95.45% | 99.14% | 0.01486 |
+| static QDQ Entropy all-ops | 2.60 MB | 5.7 | 4.1 | 95.30% | 99.13% | 0.01510 |
+| static QDQ Percentile all-ops | 2.60 MB | 5.3 | 4.3 | 96.39% | 99.17% | 0.01218 |
+
+**Verdict: static PTQ (conv-only) is the new best int8 point on accuracy —
+but only modestly, and it does not fix int8's latency penalty.**
+
+- **Accuracy: beats dynamic.** All three conv-only calibrations land at
+  PCK@20 96.60–96.63% (vs dynamic 96.52%, fp32 96.68% — recovers ~⅔ of the
+  dynamic gap) and MPJPE 0.0103–0.0108 (vs dynamic 0.01108). Best MPJPE:
+  Percentile conv-only, +10% over fp32 instead of dynamic's +18%.
+- **Size: slightly worse.** 2.53 MB vs 2.44 MB (+3.6%) — QDQ nodes and
+  per-channel scales cost a little; BatchNorm stays fp32 in both (the 12 BNs
+  follow Slice/Einsum/Reshape, never Conv, so they cannot be folded).
+- **Latency: a wash vs dynamic, still ~2× slower than ONNX fp32 at batch 1.**
+  Batch-1 medians 5.2–5.3 vs dynamic 5.7 ms/win in-session — within this
+  box's ±20–40% noise. Batch 64 leans static (3.1–3.3 for MinMax/Entropy
+  conv-only vs 4.6), same caveat.
+- **All-ops QDQ is strictly worse**: up to −1.4 pt PCK@20 and +60% MPJPE for
+  zero size/latency benefit — int8 activations through the elementwise glue
+  around the attention blocks is where the damage is. Conv-only is the right
+  scope.
+- Negative result worth recording: **Entropy calibration is a no-op here** —
+  on an identical calibration set it selects full-range thresholds
+  bit-identical to MinMax (all 247 scales equal; verified on a 64-window
+  smoke set). Also, ORT 1.26's `CalibMaxIntermediateOutputs` raises a
+  spurious "No data is collected" when the batch count divides the chunk
+  size (worked around in the script).
+
+Deployment guidance: need speed → ONNX fp32 (3.2 ms b1). Need int8 weights
+for size → static QDQ conv-only (Percentile or MinMax,
+`results/retrained_int8_static_percentile_conv.onnx`), which strictly
+dominates dynamic int8 on accuracy at ~equal latency and +0.09 MB.
+
+## Efficiency sweep (MEASURED, overnight 2026-06-10/11)
+
+ADR-152 beyond-SOTA track: compact purpose-built variants of the WiFlow-STD
+architecture, trained from scratch on the same cleaned dataset, identical
+seed-42 file-level split, loss and protocol as the measurement-(a) reference
+(fp32, batch 64, ≤50 epochs, patience 5; RTX 5080, ~22–29 min/variant).
+Variant transforms are pure channel/group/stride scalings of an
+architecture-exact parameterized model (validated: reproduces 2,225,042 params
+at the reference config). Scripts: `remote/sweep/`; raw:
+`results/efficiency_sweep.jsonl`; checkpoints `results/{half,quarter,tiny}_best.pth`
+(gitignored).
+
+| Variant | Params | vs 2.23M | Clean-test PCK@20 | PCK@50 | MPJPE | Best epoch |
+|---|---|---|---|---|---|---|
+| full (reference, meas. a) | 2,225,042 | 1× | 96.61% | 99.11% | 0.0094 | 36 |
+| **half** | **843,834** | **0.38×** | **96.62%** | **99.47%** | **0.00898** | 23 |
+| quarter | 338,600 | 0.15× | 96.05% | 99.43% | 0.00928 | 50 |
+| tiny | 56,290 | 0.025× | 94.11% | 99.36% | 0.0125 | 47 |
+
+Findings:
+
+- **The half model (843k params) strictly dominates the full reference** on
+  this dataset — equal PCK@20, better PCK@50 and MPJPE, converges in fewer
+  epochs. The published 2.23M architecture is over-parameterized for its own
+  benchmark.
+- **tiny (56k params, 1/39.5) holds 94.11% PCK@20** — a ~220 KB fp32 /
+  ~60 KB int8-class model in reach of severely constrained edge targets,
+  at −2.5 pt from the full reference.
+- Caveats: in-domain (5-subject random-file split) like every number on this
+  dataset; single run per variant; corruption-free test subset (52,560).
+  Cross-domain behavior of compact variants is untested — ADR-150's evidence
+  says capacity *hurts* cross-subject, so the compact end may generalize no
+  worse, but that is a hypothesis, not a measurement.
+
+### Compact-variant edge artifacts (MEASURED, 2026-06-11)
+
+Edge pipeline for the **tiny** checkpoint (56,290 params), same machinery and
+protocol as the full-model edge rows above (this Windows box, torch
+2.12.0+cpu, onnxruntime 1.26.0; dynamic-batch opset-17 TorchScript export;
+static QDQ **Percentile(99.99) conv-only** int8 calibrated on **512**
+corruption-free TRAIN-split windows; accuracy on the identical 10k-window
+seed-42 clean test subset; latency = median ms/window over 3 interleaved
+reps, with the full-model fp32/int8 sessions interleaved as same-session
+references). Script: `tiny_edge_bench.py`; raw:
+`results/edge_optimization.json` (`tiny_variant`). Torch-vs-ORT parity on the
+stored fixture input: **max abs diff 1.5e-7 — PASS** (< 1e-4). The tiny fp32
+subset PCK@20 (94.11%) matches the full clean-test sweep figure (94.11%)
+exactly, so the subset remains representative.
+
+Two forced deviations, both recorded in the JSON:
+
+1. **Adaptive-pool export rewrite.** tiny's derived stride schedule
+   `[2,1,1,1]` leaves feature width 16, and the TorchScript exporter rejects
+   `AdaptiveAvgPool2d((15,1))` when 15 is not a factor of the input height
+   (the full model never hit this — its width was exactly 15). Since the
+   pool over a fixed-size map is a fixed linear operator, the export wrapper
+   replaces it with `mean(-1)` (W axis, a factor) + a constant averaging
+   matmul using PyTorch's exact bin rule; the parity check (vs the original
+   torch model with the real pool) proves exactness.
+2. **Calibration count 512, not "~500"**: ORT 1.26's histogram collector
+   `np.asarray()`'s the per-batch maxima, so the calibration count must be a
+   multiple of the 64-window calibration batch or the ragged last batch
+   crashes it (the earlier static-PTQ run dodged this by using exactly 512).
+
+| Variant | Disk size | Batch 1 (ms/win) | Batch 64 (ms/win) | PCK@20 | PCK@50 | MPJPE |
+|---|---|---|---|---|---|---|
+| full ONNX fp32 (same-session ref) | 8.97 MB | 2.27 | 1.42 | 96.68% | 99.15% | 0.00936 |

+
+(tiny torch `.pth` checkpoint for reference: 0.34 MB on disk; 56,290 fp32
+params ≈ 225 KB of weights.)
+
+Findings:
+
+- **The smallest deployable WiFlow-class model is the tiny ONNX fp32
+  artifact: ~295 KB on disk, 0.66 ms/window batch-1 CPU (~1,500 windows/s),
+  94.1% PCK@20** — 30× smaller and ~3.4× faster (in-session) than the full
+  ONNX fp32 model for −2.6 pt PCK@20.
+- **int8 is a bad trade at this scale.** Static QDQ conv-only — the recipe
+  that cost the full model only 0.07 pt — costs tiny **−1.43 pt** PCK@20
+  (94.11 → 92.68%) and +19% MPJPE, saves only 47 KB (−16%; QDQ scales and
+  the fp32 BN/attention glue are proportionally larger in a small graph),
+  and is *slower* than tiny fp32 (0.85 vs 0.66 ms b1; 1.03 vs 0.24 ms b64 —
+  QDQ kernel overhead dominates when the convs are this small). A 56k-param
+  model has little redundancy left to absorb weight+activation rounding.
+- Deployment guidance, compact edition: ship tiny as **ONNX fp32** — at
+  295 KB the int8 size saving solves no real constraint and costs accuracy
+  and speed. If ~250 KB vs ~295 KB ever matters, weight-only quantization
+  would be the thing to try next, not QDQ.
+
+## Measurement (b): BLOCKED-ON-DATA (attempted 2026-06-10)
+
+The fine-tune-on-ESP32 measurement stopped at dataset characterization, per the
+pre-registered stop rule (<2,000 paired windows). Findings (MEASURED):
+
+- **Only one trainable paired dataset exists**: `ruvultra:~/work/cog-pose-train/paired.jsonl`
+  — 1,077 windows (one subject, one room, one 29.9-min session, single node;
+  CSI [56, 20]; 17 COCO keypoints, MediaPipe confidence mean 0.44 — only 264
+  windows pass ADR-079's own conf>0.5 training filter). Prior measured attempts
+  on this exact set: 0–3% torso-PCK@20 (temporal splits, three independent
+  pipelines). Fine-tuning a 2.23M-param model on ~860 train windows would
+  measure memorization, not transfer.
+- **The April session behind the old "92.9% PCK@20" claim is lost** (345
+  samples, 35 subcarriers; raw CSI gone from ruvzen/ruvultra/cognitum-v0; only
+  a 69-sample predictions+GT holdout survives at `models/wiflow-real/eval-holdout.jsonl`).
+- **Forensic recheck of that holdout RETRACTS the 92.9% figure**: the trainer's
+  `pck()` used an absolute 0.2 image-unit threshold (not torso-normalized) and
+  the model output a **constant pose** (pred std 0.0000 across 69 near-static
+  frames; a mean predictor scores 100% under the same protocol). The
+  torso-normalized PCK@20 on the same holdout is 19.1%. This corroborates the
+  2026-05-11 audit retraction (CHANGELOG, PR #535); stale doc citations were
+  removed 2026-06-10 (user-guide, readme-details, ADR-152 §2.1.3). The §2.2
+  no-citation rule now applies to ADR-079 accuracy claims.
+
+Unblock criteria: a paired collection session of ≥2k windows (≈35+ min at the
+observed stride; multi-pose, conf>0.5, ideally with the §2.1.3 two-checkerboard
+calibration), plus a re-baselined our-pipeline number under torso-PCK@20 on the
+same split. WiFlow-STD assets stand ready on ruvultra (`~/wiflow-std-bench/`).
+Also worth investigating: ADR-079's protocol predicts ~9k windows per 30 min;
+the May session under-delivered ~8× (aligner drop rate?).
+
+## Measurement (b) (MEASURED 2026-06-10/11)
+
+The data baseline unblocked: the 2026-06-10 22:10–22:40 collection session produced
+**2,046 paired windows** (`ruvultra:~/wiflow-std-bench/paired-20260610.jsonl`; ONE
+subject, ONE room, ONE ESP32 node, varied poses: walk/raise/squat/kick/wave/turn/
+jump/sit; aligner `scripts/align-ground-truth.js`, non-overlapping 20-frame windows
+~0.42 s; 17 COCO keypoints in normalized [0,1] camera coords; MediaPipe confidence
+mean 0.802, min 0.692 — all windows pass the conf>0.5 filter). The −4 h timestamp
+bug and the empty-frame confidence-dilution aligner findings are recorded
+separately; results only here. Trained on ruvultra (RTX 5080, torch 2.11+cu128,
+fp32, batch 32, GPU shared with the efficiency sweep). Scripts mirrored in
+`remote/measb/`; raw metrics + full training curves in `results/measurement_b.json`.
+
+### Two new aligner/dataset findings (forced deviations, MEASURED)
+
+1. **`csi_shape` is heterogeneous, not [70, 20]**: 1,347× [70,20], 284× [134,20],
+   243× [26,20], 130× [12,20], 42× [20,20]. The ESP32 stream emits mixed frame
+   types and `extractCsiMatrix` stamps each window's subcarrier count from
+   `window[0].subcarriers`, zero-padding/truncating the other frames — even
+   native-70 windows contain ~20.4% internally zero-padded short frames
+   (subcarriers 40–69 all-zero). Handling: the primary suite ("all 2,046")
+   linearly resamples every frame's subcarrier axis to 70 bins (identity for
+   native-70 frames) so the pre-registered n and split sizes hold; a secondary
+   suite restricts to the 1,347 native [70,20] windows as a homogeneity check.
+2. **Aligner layout bug**: `extractCsiMatrix` fills `matrix[f * nSc + s]`
+   (frame-major) but declares `shape: [nSc, nFrames]` — the stored shape label is
+   transposed relative to the data. Confirmed by coherent per-frame zero-tails;
+   corrected on load (`reshape(nFrames, nSc).T`).
+
+### Protocol (pre-registered, followed)
+
+Temporal split, no shuffling across time: first 70% train (1,432), next 15% val
+(307), last 15% test (307); seed 42 elsewhere. Model: learned 1×1 Conv1d 70→540
+adapter prepended to the upstream WiFlow-STD trunk; K=17 via the parameter-free
+adaptive pool (`AdaptiveAvgPool2d((17,1))` — pretrained weights load strict for
+any K). CSI normalized by the TRAIN-split p99 amplitude (129.7 all / 130.9
+native-70), clipped to [0,1]. Three runs, ≤60 epochs, early-stop patience 8 on
+val MPJPE, AdamW (adapter lr 1e-4; pretrained trunk lr 1e-5, 10× lower; scratch
+all 1e-4), fp32. Pretrained init = the measurement-(a) **retrained** checkpoint
+(`upstream/test/best_pose_model.pth`, ~96% PCK@20 on WiFlow data; the
+`att.`/`final_conv.` key remap from `eval_repro.py` applied defensively — a no-op,
+that checkpoint already uses post-rename keys). Frozen-trunk run: trunk
+`requires_grad=False` **and** held in `.eval()` so BatchNorm running stats cannot
+drift — a pure transfer probe; only the 70→540 adapter (38,340 params) trains.
+
+PCK is torso-normalized with **torso = ‖l_shoulder(5) − l_hip(11)‖** (upstream
+`calculate_pck` math — per-frame norm clamped at 0.01, mean over keypoints ×
+frames — but upstream's `NECK_IDX/PELVIS_IDX = 2, 12` is a 15-keypoint
+convention; on 17-kp COCO those indices are right_eye/right_hip, so the indices
+were replaced, not the math). MPJPE is in normalized image units (not meters).
+
+### Results — primary suite, all 2,046 windows (test = last 307)
+
+| Run | PCK@10 | PCK@20 | PCK@30 | PCK@40 | PCK@50 | MPJPE | pred std | best ep |
+|---|---|---|---|---|---|---|---|---|
+| **mean-pose baseline** (honesty bar) | **73.1%** | **95.9%** | **98.7%** | 99.3% | 99.3% | **0.0148** | 0 (by constr.) | — |
+| (i) pretrained-init, full fine-tune | 26.0% | 65.0% | 88.0% | 96.4% | 98.9% | 0.0313 | 0.0113 | 58/60 |
+| (ii) scratch | 0.0% | 0.0% | 0.0% | 0.0% | 0.0% | 0.2554 | 0.0002 | 4 (stop @13) |
+| (iii) frozen-trunk (adapter only) | 0.0% | 0.0% | 0.2% | 3.2% | 14.4% | 0.1260 | 0.0073 | 59/60 |
+
+Secondary suite (native [70,20] windows only, n=1,347, test=202) reproduces the
+same ordering: mean-baseline 96.0% / pretrained 67.1% / scratch 0.0% /
+frozen-trunk 0.0% PCK@20 (MPJPE 0.0153 / 0.0318 / 0.2236 / 0.1343) — the
+subcarrier-resampling choice does not change any conclusion.
+
+### Interpretation
+
+- **Did pretraining-transfer happen? Partially — as optimization transfer, not
+  feature transfer, and not past the honesty bar.**
+  - *Pretrained vs scratch*: dramatic (65.0% vs 0.0% PCK@20). The pretrained init
+    is the only configuration that trains at all under the pre-registered budget.
+  - *Frozen-trunk*: near-zero (0.0% PCK@20, 14.4% @50). WiFlow-STD's frozen
+    features do **not** transfer to our ESP32 domain through a linear subcarrier
+    adapter — the pretrained benefit is a well-conditioned initialization (incl.
+    calibrated BN/output scales), not reusable CSI→pose features.
+  - *Everything vs mean-pose baseline*: **no run beats it.** A constant
+    train-mean pose scores 95.9% torso-PCK@20 / 0.0148 MPJPE on this test split,
+    because a single subject in one camera frame barely moves in normalized
+    coordinates. The fine-tuned model is a real, non-constant model
+    (pred std 0.0113 > 0 — passes the constant-pose detector that retracted the
+    old 92.9% figure) but its deviations from the mean hurt: it fits train-period
+    temporal dynamics that do not generalize across the temporal split.
+- **Verdict for ADR-152 §2.2(b): fine-tuning WiFlow-STD on this dataset does not
+  demonstrate CSI→pose signal beyond the mean pose.** Until a model beats the
+  mean-pose baseline on a temporal split, no PCK number from this line may be
+  cited as pose-estimation capability.
+
+### Caveats (honest, pre-registered)
+
+- Single subject, single room, single session (30 min), single ESP32 node —
+  in-domain temporal split only; nothing here speaks to cross-room or
+  cross-subject generalization.
+- 2k windows vs the 360k-window WiFlow-STD corpus — **NOT comparable** to the
+  ~96% in-domain measurement-(a) number, and the published 97.25% even less so.
+- The scratch run's total collapse (it cannot even reach the mean pose; its
+  output BatchNorm/SiLU head must learn output scale from random init at lr 1e-4)
+  is an optimization outcome under the fixed budget, not proof the architecture
+  cannot learn from scratch — the pretrained-vs-scratch gap partially reflects
+  this conditioning advantage.
+- Mixed-subcarrier frames (finding 1) mean even the "clean" windows carry ~20%
+  zero-padded frames; collection-side frame-type filtering should precede the
+  next session.
+- Mean-baseline PCK is inflated by low pose variance relative to torso size
+  (~0.2–0.3 image units); PCK@10 (73.1%) shows the same ceiling effect at a
+  stricter threshold — the bar is the bar, but a livelier dataset would lower it.
+
+## Pending
+
+- (b) fine-tune on our ESP32 17-keypoint eval set — **MEASURED 2026-06-10/11**,
+  see above: no run beats the mean-pose baseline; pretraining transfers as
+  optimization aid only.
+- (c) our internal WiFlow on their dataset (15-keypoint subset mapping) — also
+  affected: there is currently no validated internal pose model to compare
+  (the 92.9% artifact is retracted; the MM-Fi SOTA models in ADR-150 §3 are a
+  different input domain).

+
+============================ READ THIS FIRST ===============================
+This script MUST be run against an UNCLEANED copy of the dataset.
+
+remote/clean_v2.py (and its predecessor clean_nan.py) repair the dataset by
+zeroing the corrupted windows IN PLACE, with no backup. A cleaned copy
+contains no non-finite values and no out-of-range amplitudes, so on a cleaned
+copy this scan produces ALL-FALSE masks -- silently wrong ground truth. The
+script errors out loudly in that case (see the sanity check in main()).
+
+That irreversibility is exactly why the two committed mask files under
+results/ (gitignore-negated) are the canonical ground truth: once a download
+has been cleaned, the masks can NEVER be regenerated from it. Only run this
+on a fresh `kagglehub.dataset_download("kaka2434/wiflow-dataset")`.

+"""ADR-152 edge optimization: ONNX export + onnxruntime CPU benchmark for the
+retrained WiFlow-STD checkpoint.
+
+- Exports fp32 to ONNX. The axial attention reshapes with python ints taken
+  from tensor.size() (view(N*W, C, H)), so a traced graph bakes the batch
+  size; we first try a dynamic-batch export and verify it actually works at
+  batch sizes 1/2/64 -- if not, we fall back to fixed-batch exports.
+- Verifies output parity vs torch on the stored fixture
+  (results/parity_fixture.npz, batch 2, seed 42): max abs diff < 1e-4.
+- Measures onnxruntime CPU latency at batch 1 and 64 (median of N runs).
+- Supplementary: onnxruntime dynamic int8 quantization of the exported model
+  (weight size datapoint for the paper's "~2.2 MB int8" claim).

+"""ADR-152 SS2.2 measurement (b): WiFlow-STD fine-tuned on our fresh ESP32 paired dataset.
+
+Dataset: ~/wiflow-std-bench/paired-20260610.jsonl -- 2,046 paired windows collected
+2026-06-10 22:10-22:40 (ONE subject, ONE room, ONE ESP32 node, varied poses).
+Per record: csi = flat float32 list, csi_shape, kp = 17 COCO [x, y] normalized [0,1]
+camera coords, conf (MediaPipe mean confidence, all > 0.5 in this set), ts_start/ts_end.
+Aligner: scripts/align-ground-truth.js, non-overlapping 20-frame windows (~0.42 s each).
+
+Dataset findings (MEASURED on this file, 2026-06-10):
+  - csi_shape is HETEROGENEOUS, not uniformly [70, 20]: 1,347x [70,20], 284x [134,20],
+    243x [26,20], 130x [12,20], 42x [20,20]. The ESP32 stream emits mixed frame types
+    and the aligner stamps each window's subcarrier count from frame[0]
+    (extractCsiMatrix: nSc = window[0].subcarriers), zero-padding/truncating the rest.
+    Even native-70 windows contain ~20.4% internally zero-padded short frames
+    (subcarriers 40..69 all-zero for those frames).
+  - LAYOUT BUG: the aligner fills matrix[f * nSc + s] (frame-major) but declares
+    shape [nSc, nFrames]. The true layout is (frame, subcarrier); we reshape
+    (nFrames, nSc) and transpose. Confirmed by coherent per-frame zero-tails.
+  - Handling here (primary suite, "all2046"): every frame's subcarrier axis is
+    linearly resampled to 70 bins (np.interp over a normalized index domain;
+    identity for native-70 frames) so the pre-registered n=2,046 and split sizes
+    hold. Secondary suite ("native70") restricts to the 1,347 native [70,20]
+    windows (temporal 70/15/15 of those) as a homogeneity robustness check.
+
+Pre-registered protocol (followed exactly):
+  1. TEMPORAL split (records are time-sorted; asserted): first 70% train (1,432),
+     next 15% val (307), last 15% test (307). No shuffling across time. Seed 42
+     for everything else.
+  2. Model: upstream WiFlow-STD trunk (WiFlowPoseModel) with a learned 1x1 Conv1d
+     projection 70->540 prepended, and K=17 via the parameter-free adaptive pool
+     (AdaptiveAvgPool2d((17, 1)) instead of (15, 1)) -- pretrained weights load
+     for any K. CSI normalization: divide by the TRAIN-split 99th-percentile
+     amplitude, clip to [0, 1] (documented in output JSON).
+  3. Three runs, <=60 epochs, early-stop patience 8 on val MPJPE, batch 32,
+     AdamW, fp32 (no autocast):
+       (i)   pretrained-init: trunk init from upstream/test/best_pose_model.pth
+             (the measurement-(a) retrained checkpoint, ~96% PCK@20 on WiFlow data;
+             key remap att.->attention. / final_conv.->decoder. applied defensively
+             as in eval_repro.py -- a no-op for this checkpoint, which already uses
+             the new names). Discriminative lr: adapter 1e-4, trunk 1e-5.
+       (ii)  scratch: same architecture, random init, all params lr 1e-4.
+       (iii) frozen-trunk: pretrained trunk frozen (requires_grad=False AND held in
+             .eval() so BatchNorm running stats cannot drift -- pure transfer probe);
+             only the 70->540 adapter trains, lr 1e-4.
+  4. Metrics on the temporal TEST split: torso-normalized PCK@10/20/30/40/50 and
+     MPJPE. Upstream utils/metrics.py calculate_pck(use_torso_norm=True) hardcodes
+     NECK_IDX/PELVIS_IDX = 2, 12 -- a 15-keypoint convention that is WRONG for our
+     17 COCO keypoints (2 = right_eye, 12 = right_hip). We therefore reimplement the
+     identical math (per-frame norm distance, clamp min 0.01, mean over all
+     keypoints x frames) with torso = ||l_shoulder(5) - l_hip(11)||.
+     Also reported: prediction std across test frames (constant-pose detector;
+     must be > 0) and the mean-pose-predictor baseline (train-split mean pose
+     evaluated on test -- the honesty bar).
+
+Usage (on ruvultra):
+  nice -n 10 nohup ~/wiflow-std-bench/venv/bin/python train_measb.py > train_measb.log 2>&1 &

+"""Configurable compact variants of the WiFlow-STD pose model (ADR-152 efficiency sweep).
+
+This is a parameterized copy of upstream models/{pose_model,tcn,convnet,attention}.py
+(DY2434/WiFlow @ 06899d29, Apache-2.0). upstream/ is NOT modified. Deviations from
+upstream, all forced by shrinking channels and documented per variant in run_sweep.py:
+
+1. TCN grouped-conv groups: upstream hardcodes groups=20, which does not divide
+   the compact channel counts (e.g. 270, 135, 85). Rule here:
+   - groups_mode='gcd20': per-conv groups = gcd(channels, 20)  (== 20 wherever
+     upstream's choice is valid, incl. the 540-ch input conv; falls back to the
+     largest common divisor with 20 otherwise).
+   - groups_mode='depthwise': groups = channels (tiny variant only).
+2. Conv2d downsampling strides: upstream uses 4 stride-(1,2) blocks because
+   240/2^4 = 15 == n_keypoints. With smaller TCN output widths that would leave
+   <15 rows and AdaptiveAvgPool2d((15,1)) would duplicate rows across keypoints.
+   Rule: halve the width only while the result stays >= 15 (stride-2 blocks
+   first, stride-1 after). Full model: 240 -> 4 halvings = upstream exactly.
+3. input_pw_groups (tiny only): the dense 540->c pointwise + residual downsample
+   in TCN block 1 cost 2*540*c params (a ~117k floor that alone exceeds the
+   tiny <100k budget). tiny groups these two convs (groups=4; 4 | gcd(540, 68)).
+4. Decoder mid-channels: upstream 64->32; here c_last -> max(c_last // 2, 4).

+"""WiFlow-STD compact-variant efficiency sweep (ADR-152) — sequential overnight runner.
+
+Trains compact variants of the upstream WiFlow-STD architecture on the same
+data/split as the full-size reference retraining (seed 42, file-level 70/15/15,
+upstream dataset.py) and evaluates PCK@10..50 + MPJPE on the full test split and
+the corruption-free test subset (file indices < 487).
+
+Training mirrors upstream run.py/train.py defaults except:
+- fp32 only (no fp16 autocast / GradScaler — avoids the BN-poisoning trap
+  documented in RESULTS.md defect 5; data on disk is already cleaned).
+- batch 64 (kept modest: another GPU job may share the 16 GB card tonight).
+- scheduler + early stopping keyed on val MPJPE (upstream early-stops on val MPE
+  with patience 5; same here).
+
+Usage:
+  venv/bin/python sweep/run_sweep.py --dry-run    # param counts only
+  nohup venv/bin/python sweep/run_sweep.py > sweep/sweep.log 2>&1 &
+
+Idempotent: variants already present in sweep/results.jsonl are skipped.
+
+NOTE: deployed to ruvultra (~/wiflow-std-bench/sweep) as a standalone file, so
+it deliberately inlines its helpers. The reference implementations (upstream
+import shim, >1GB np.load mmap patch, key-remap loader, canonical evaluate
+loop) live in benchmarks/wiflow-std/_bench_common.py — keep copies in sync.

+"""ADR-152 edge optimization follow-up: ONNX Runtime STATIC post-training
+quantization (calibration-based QDQ) of the retrained WiFlow-STD model, to
+improve on the dynamic-int8 result (2.44 MB, PCK@20 96.52%, 6.5 ms/win b1).
+
+Static PTQ pre-computes activation ranges from calibration data, so inference
+uses QLinearConv/QDQ kernels instead of dynamic ConvInteger -- typically both
+faster and (with good calibration) closer to fp32 accuracy.
+
+Method:
+  - Calibration set: corruption-free windows drawn ONLY from the seed-42
+    file-level TRAINING split (same split as eval_repro.py; corrupted windows
+    excluded via results/nan_windows_mask.npy | big_windows_mask.npy), chosen
+    with np.random.default_rng(42). Never test windows.
+  - quantize_static, QuantFormat.QDQ, per-channel int8 weights, int8
+    activations; calibration methods MinMax / Entropy / Percentile(99.99);
+    scopes "all" (ORT default op set) vs "conv" (op_types_to_quantize=
+    ["Conv"] -- leaves the attention path, which exports as Einsum/Softmax
+    and elementwise ops, in fp32).
+  - Model is pre-processed first (quant_pre_process: symbolic shape
+    inference + ORT graph optimization, folds BatchNormalization into Conv).
+  - Accuracy: identical protocol to eval_ort_accuracy.py -- the 10,000-window
+    seed-42 subset of the corruption-free test split (PCK@20/50, MPJPE).
+  - Latency: median ms/window at batch 1 (100 runs) and batch 64 (30 runs),
+    3 interleaved repetitions across all variants (fp32 and dynamic-int8
+    sessions included as same-session reference points).
+
+Usage:
+  PYTHONUTF8=1 .venv/Scripts/python.exe static_ptq_bench.py \
+      [--data-dir <preprocessed_csi_data>] [--subset 10000]

+"""ADR-152 efficiency-sweep follow-up: edge pipeline for the TINY compact
+WiFlow-STD variant (56,290 params, results/tiny_best.pth, trained overnight
+2026-06-10/11 -- see RESULTS.md "Efficiency sweep").
+
+Headline question: what does the smallest deployable WiFlow-class model look
+like (KB + ms + PCK)? Reuses the onnx_bench.py / static_ptq_bench.py
+machinery on the tiny checkpoint:
+
+  1. Load tiny_best.pth with remote/sweep/model_compact.py
+     (depthwise TCN groups, input_pw_groups=4, conv [2,4,8,16], attn groups 2).
+  2. Export ONNX: dynamic batch, opset 17, TorchScript exporter (dynamo=False)
+     -- same recipe that worked for the full model; verified at batch 1/2/64.
+     One forced deviation: tiny's stride schedule [2,1,1,1] leaves final_width
+     16, and the TorchScript exporter cannot export AdaptiveAvgPool2d((15,1))
+     when 15 is not a factor of the input height (the full model never hit
+     this -- its width was exactly 15). The adaptive pool over a fixed-size
+     feature map is a fixed linear map, so the export wrapper replaces it with
+     an exact matmul equivalent (PyTorch adaptive-pool bin semantics:
+     bin i averages rows floor(i*H/K)..ceil((i+1)*H/K)); the W axis (20->1,
+     a factor) becomes mean(-1). Exactness is proven by the parity check
+     below, which compares against the ORIGINAL torch model with the real
+     AdaptiveAvgPool2d.
+  3. Torch-vs-ORT parity on the stored fixture input
+     (results/parity_fixture.npz, batch 2, seed 42 -- same 540x20 input layout;
+     reference output recomputed with the tiny torch model). PASS < 1e-4.
+  4. Static QDQ conv-only int8 (quant_pre_process + quantize_static,
+     per-channel QInt8 weights+activations, Percentile(99.99) calibration on
+     512 corruption-free TRAIN-split windows -- the winning recipe and
+     calibration count from static_ptq_bench.py. 512, not "about 500":
+     ORT 1.26's histogram collector np.asarray()'s the per-batch maxima, so
+     the calibration count must be a multiple of the batch size 64 or the
+     ragged last batch crashes it).
+  5. Disk size + CPU latency b1/b64 (3 interleaved reps, median ms/window)
+     for tiny fp32 + tiny int8, with the full-model ONNX fp32 + static-int8
+     sessions interleaved as same-session references.
+  6. Accuracy (PCK@20/50 + MPJPE) on the identical 10k-window seed-42
+     corruption-free test subset for tiny fp32 + tiny int8.
+
+Usage:
+  PYTHONUTF8=1 .venv/Scripts/python.exe tiny_edge_bench.py \
+      [--data-dir <preprocessed_csi_data>] [--subset 10000] [--calib 512]
+  (--calib must be a multiple of 64; see step 4 above)

+## Implementation Notes
+
+### 2026-06 — ESP32 edge vitals: person-count over-count + presence flicker (#998, #996)
+
+Two robustness bugs were fixed in the on-device edge path (`firmware/esp32-csi-node/main/edge_processing.c`, the ADR-039 packet `0xC5110002`). These touch the *boolean/count emission logic*, not the underlying CSI signal-processing math, and do **not** constitute a validated-accuracy claim — true occupancy-count and presence accuracy vs labelled ground truth remain hardware/data-gated (COM9 ESP32-S3 + labelled capture).
+
+- **#998 `n_persons` over-count (reported 4 for one person).** `update_multi_person_vitals()` divided the top-K subcarriers into `top_k_count/2` groups and marked *every* group `active`, so one body's multipath always read the full `EDGE_MAX_PERSONS`. Added an energy gate (`EDGE_PERSON_MIN_ENERGY_RATIO`), spatial dedup (`EDGE_PERSON_MIN_SC_SEP`), and a persistence debounce (`EDGE_PERSON_PERSIST_FRAMES`) via two pure functions `count_distinct_persons()` / `person_count_debounce()`.
+- **#996 presence flag flicker at ~50 cm.** Single-threshold compare on a noisy `presence_score` chattered at the boundary. Replaced with a Schmitt trigger + clear-debounce (`presence_flag_update()`, constants `EDGE_PRESENCE_HYST_RATIO` / `EDGE_PRESENCE_CLEAR_FRAMES`); `presence_score` is unchanged and still emitted for consumer-side thresholding.
+
+Both are pinned by host-buildable C99 tests in `firmware/esp32-csi-node/test/test_vitals_count_presence.c` (`make run_vitals`). The exact thresholds are documented constants pending on-device calibration against ground truth.
+
+### 2026-06 — Rust `wifi-densepose-vitals`: IIR filter NaN/inf self-heal (ADR-158 §A1)
+
+A correctness/safety review of the Rust extraction crate found a real bug parallel to the firmware robustness class above. The 2nd-order resonator `bandpass_filter` in both `breathing.rs` and `heartrate.rs` latches each output `y[n]` into its filter state (`y1`/`y2`). A single non-finite amplitude residual from a corrupt CSI frame produced a NaN `output` that was written into the state; the existing `extract()` `is_finite()` guard dropped that one sample from the history buffer **but never sanitized the poisoned filter state**, so every later output stayed NaN, was rejected too, and the sliding-window history never refilled — breathing **and** heart-rate extraction went silently dead (returning `None` forever) until `reset()`. On the alert path this is a safety-relevant denial of service (one bad frame stops vitals monitoring with no error surfaced).
+
+Fix: when `bandpass_filter` computes a non-finite `output`, it resets the IIR state to default and returns `0.0`, so the resonator self-heals on the next clean frame (the `0.0` is still dropped by the caller's finite-check, so no spurious sample enters history). Same shape as the calibration NaN bug (ADR-154 §3) — the prior hardening guarded the *history boundary* but not the *filter-state boundary*. Pinned by `breathing::tests::nan_frame_does_not_permanently_poison_filter`, `breathing::tests::inf_mid_stream_does_not_freeze_history`, and `heartrate::tests::nan_frame_does_not_permanently_poison_filter` (all FAIL pre-fix, verified by reverting). The review also de-magicked the HR physiological plausibility band into named `HR_PLAUSIBLE_MIN_BPM`/`HR_PLAUSIBLE_MAX_BPM` consts (value-identical 40/180 BPM) and added a fabricated-vital negative (`pure_noise_is_never_reported_valid` — broadband noise never yields a clinically `Valid` HR; the extractor honestly returns low-confidence `Unreliable`). Clean dimensions confirmed with evidence: flat/silent input → `None`; pure noise → low-confidence `Unreliable`, never `Valid`; harmonic-rich breathing with no cardiac component → low-confidence, not a confident false HR; out-of-band BPM rejected by the plausibility clamp.

+## Security P0 closure note (2026-06-13) — Rust sensing-server boundary
+
+The three P0 security findings below were logged against the **Python v1** API
+(`archive/v1/src/…`). ADR-164 G11 re-scoped them to the *shipped* boundary:
+`wifi-densepose-sensing-server` (Rust). They were verified against the current
+Rust crate and closed on branch `fix/adr-080-sensing-server-security`. Each fix
+(or already-fixed finding) is pinned by a test that fails on the old behavior.
+**The Python v1 paths remain as-is** — v1 is archived and not the shipped
+surface; this closure governs the live Rust server only.

 - **Problem:** Trusts `X-Forwarded-For` without validation. Any client bypasses rate limits via header spoofing.
-- **Fix:** Validate forwarded headers against trusted proxy list, or use connection IP directly.
+- **Rust verification (2026-06-13):** The Rust sensing-server has **no XFF-trusting control to bypass** — there is no IP-based rate-limiter and no IP-allowlist, and neither security middleware reads a forwarded header. `bearer_auth.rs` authenticates on the token alone (`require_bearer` inspects only the `AUTHORIZATION` header); `host_validation.rs` decides on the `Host` header only. A repo-wide grep for `x-forwarded-for|forwarded|peer_addr|client_ip|real-ip` over `wifi-densepose-sensing-server` returns nothing. The only "rate limiter" is the MQTT *sample-rate* gate (`mqtt/state.rs`), a per-entity publish throttle with no IP/header input.
+- **Resolution:** No code change needed (no vulnerable surface). Regression tests pin the immunity: `bearer_auth::tests::xff_header_never_affects_auth_decision` (spoofed XFF never flips a 401↔200 decision) and `host_validation::tests::forwarded_headers_never_bypass_host_allowlist` (spoofed `X-Forwarded-Host: localhost` never lets a foreign `Host: evil.com` past the allowlist). Residual: if an IP-based control is ever added, it must derive the peer from the socket (`ConnectInfo<SocketAddr>`) and only honor XFF from an explicit `--trusted-proxy` CIDR — captured as guidance in the test docstrings.

+## Pass 2 — randomized rotation + multi-bit (ADR-156 §8, landed 2026-06)
+
+The "Open question" below ("does `BinaryQuantized` need a randomized
+rotation pre-pass?") is now **answered with measured numbers** via
+ADR-156 §10. Summary:
+
+- **Pass 2 (randomized rotation) is implemented** —
+  `crates/wifi-densepose-ruvector/src/rotation.rs`: a deterministic
+  `R = H·D` (Fast Hadamard Transform + seeded ±1 sign flips), `O(d log d)`
+  / `O(d)`, norm-preserving, reproducible from a stored `u64` seed. Opt-in
+  via `Sketch::from_embedding_rotated` / `SketchBank::with_rotation`;
+  Pass-1 API and wire format unchanged.
+- **Measured top-K coverage** (anisotropic planted-cluster fixture,
+  cosine ground truth, dim=128 N=2048 K=8): rotation lifts coverage
+  **36.13% → 46.39%** at the strict `candidate_k = K` bar, and Pass-2
+  reaches the **≥90% acceptance bar at candidate_k = 24 (~3× over-fetch)**.
+  Multi-bit (≤4-bit) reaches 74% at the strict bar. **Honest verdict:
+  neither rotation nor ≤4-bit multi-bit clears the strict-K 90% bar on
+  this distribution; the bar is met via the over-fetch "candidate set"
+  pattern this ADR specifies** (Decision §"the canonical pattern" — sketch
+  picks the candidate set, full precision refines). Full numbers and
+  reproduce commands in ADR-156 §10.
+- **Pre-existing `SketchBank::topk` bug fixed** — the `n > k` heap path
+  returned the k *farthest* sketches (min-heap mistaken for max-heap);
+  only the `n ≤ k` fast path had test coverage. Fixed + regression-pinned
+  (`topk_heap_path_returns_nearest`,
+  `tight_clusters_give_high_coverage_with_overfetch`). This makes every
+  prior top-K acceptance number in this ADR depend on the fixed path; the
+  ≥90% coverage criterion is only meaningful post-fix.
+
+## Pass 2b — RaBitQ unbiased distance estimator (ADR-156 §11, landed 2026-06)
+
+The **real** RaBitQ contribution (Gao & Long, SIGMOD 2024) — an
+**unbiased estimator of the inner product / distance** from the 1-bit
+code + per-vector side info, not just sign bits — is now implemented and
+**MEASURED against this ADR's ≥90% strict-K bar**:
+
+- **Implemented** — `crates/wifi-densepose-ruvector/src/estimator.rs`:
+  `EstimatorSketch` (Pass-2 sign code + 8 B/vec side info:
+  `residual_norm` + `x_dot_o = ⟨x̄, o'⟩`), `DistanceEstimator`
+  (`⟨o',q'⟩ ≈ ⟨x̄,q'⟩ / x_dot_o`, the paper's unbiased rescale), and
+  `EstimatorBank` reranking candidates by the estimate instead of raw
+  Hamming. **Zero-centroid simplification** (`c = 0`) documented;
+  paper-faithful centroid path also built (`with_centroid`). Additive —
+  Pass-1/Pass-2 and the wire format are unchanged.
+- **MEASURED strict-K coverage** (same fixture as §"Pass 2", cosine
+  ground truth): the estimator lifts the strict `candidate_k = K` bar
+  **46.39% (Pass-2 sign) → 49.71% (estimator, cosine rerank)** — a real
+  **+3.3 pp** lift, but **still ~40 pp short of the ≥90% strict bar.**
+  At over-fetch the estimator does better than sign (95.12% vs 91.60% at
+  candidate_k = 24). **Honest verdict: the unbiased estimator does NOT
+  clear the strict-K 90% bar on this distribution** — the binding
+  constraint is the 1-bit code's information ceiling, not estimator
+  variance. The ≥90% acceptance bar is still met only via the over-fetch
+  "candidate set" pattern this ADR's Decision specifies; the estimator
+  **reduces the over-fetch factor** needed but does not remove it. This
+  is a **published negative**, reported as such. Full numbers + reproduce

 ## Open questions
 
 - **Does `BinaryQuantized` need a randomized rotation pre-pass for
-  RuView's embedding distributions?** Pure sign quantization assumes
-  zero-centered, isotropic embeddings. If AETHER / spectrogram
-  distributions are skewed (likely for spectrogram), add a
-  `randomized_rotation` pre-pass following the original RaBitQ paper
-  (Gao & Long, SIGMOD 2024). Decided after pass-1 benchmark.
+  RuView's embedding distributions?** **ANSWERED (ADR-156 §10):** rotation
+  is built and measured — it helps (+10pp at strict K) but is not
+  sufficient alone for strict-K 90% on the tested anisotropic
+  distribution; the over-fetch candidate-set pattern meets the bar.
+  Pure sign quantization assumes zero-centered, isotropic embeddings; the
+  rotation decorrelates anisotropic coords as the RaBitQ paper
+  (Gao & Long, SIGMOD 2024) prescribes.
 - **Sketch dimension target.** Default to the embedding's native
   dimension (128 for AETHER, 256 for spectrogram). Higher-dimensional
   sketches (Johnson-Lindenstrauss-projected to 512) trade compute for

+## 4.1 Crypto/security review notes (§2.2 witness chain — ADR-262 P2 prerequisite)
+
+Beyond-SOTA crypto+security review of the SHA-256 + Ed25519 witness chain
+(`witness.rs` / `witness_signing.rs`) and the manifest signature surface
+(`manifest.rs`), because ADR-262 P2 proposes to **reuse this exact signing
+chain**. Top priority was the sibling `wifi-densepose-engine` bug class —
+unframed boundary-to-boundary concatenation of operator-influenceable strings
+into a signed/hashed digest.
+
+- **Engine bug class ABSENT (good result, reported with byte evidence).**
+  `canonical_bytes` is `DOMAIN_TAG ‖ prev_hash[32] ‖ seq:u64-be ‖ ts:u64-be ‖
+  kind_len:u32-be ‖ kind ‖ payload_len:u32-be ‖ payload`. The two
+  variable-length operator-influenceable fields (`kind`, `payload`) are
+  **length-prefixed**; the fixed-width fields are self-delimiting → the
+  encoding is injective (no two distinct event tuples share a preimage). The
+  Ed25519 signature signs the **identical** bytes the SHA-256 chain commits to.
+  No separate unframed concatenation exists; the manifest `binary_signature`
+  is signed at build time (Makefile) over a single fixed-length `binary_sha256`
+  hex value, not in-crate.
+
+- **CHM-WIT-01 (FIXED) — domain-separation tag added.** The engine fix
+  prescribed *domain-tag + length-prefix*; length-prefix was present, the
+  domain tag was not. Added a versioned, NUL-terminated
+  `WITNESS_DOMAIN_TAG = b"cog-ha-matter/witness-event/v1\x00"` prefix so the
+  witness message can never be replayed as a message for another Ed25519
+  context that shares key infrastructure (notably the manifest signature).
+  **Witness bytes change by design** (prior on-disk hashes/signatures
+  invalidated, as with the engine fix); verified safe because no in-repo crate
+  consumes cog-ha-matter witness bytes programmatically (doc-mentions only).
+
+- **CHM-WIT-02 (HARDENED) — `verify_signature` now uses `verify_strict`.** For
+  an audit chain the signature is the attestation, so non-canonical encodings
+  and small-order keys are rejected (RFC 8032 strict), giving the "one
+  canonical signature per event" property. Not a forgery fix — the verifying
+  key is caller-pinned, never read from the event.
+
+- **Confirmed clean (with evidence):** verify-before-trust + key-pinning
+  (`verify_signature` takes the verifying key as a parameter; `read_jsonl`
+  re-derives every hash and chain-verifies); key handling (the crate never
+  generates/stores/logs/serializes a signing key — only a documented test-only
+  fixed seed; production keys come from the Seed secure store, out of scope);
+  determinism (positional bytes, deterministic Ed25519, alphabetically-locked
+  JSONL field order, sorted TXT records — no HashMap/float nondeterminism feeds
+  any digest); fail-closed parsing (structured errors, no panics; `main.rs`
+  reads no untrusted files/paths).
+
+Tests: `cog-ha-matter --no-default-features` 64 → **68**, 0 failed (CHM-WIT-01
+pinned by 4 fails-on-old tests across `witness.rs`/`witness_signing.rs`;
+CHM-WIT-02 guarded by a key-pinning test). Python deterministic proof
+unchanged (cog-ha-matter is off the signal proof path).

+## 9. Security & concurrency review (P1 core, beyond-SOTA sweep)
+
+Foundational review of the `homecore` crate — the state store + event bus +
+service/entity registries every other HOMECORE module trusts. Same rigor as
+the ADR-129/130/132/133/161 sibling reviews. **Three real fixes (one
+concurrency, two hardening), each pinned by a fails-on-old test; the bus-lag
+and lock-discipline dimensions confirmed clean with evidence.**
+
+- **HC-RACE-01 (state-set TOCTOU — lost / reordered `state_changed`, the
+  crux). FIXED.** `StateMachine::set` did `get()` (releasing the DashMap
+  shard lock) → compute the next snapshot + the no-op / `last_changed`
+  decision → `insert()` (re-acquiring the lock) → `send()`. The
+  read-modify-write was **not atomic** w.r.t. a concurrent writer on the
+  same entity, contradicting §2.1's promise that "the writer atomically
+  replaces the map entry." A writer that read a stale `old` could
+  mis-classify a genuine transition as a no-op and **drop its
+  `state_changed` event** (a missed automation trigger) or fire an event
+  whose `new_state` duplicated the previously delivered one (a spurious
+  trigger for any automation keyed on `old_state != new_state`). **Fix:**
+  hold the shard write-lock across the entire read→decide→insert→fire
+  sequence via `entry()`/`insert_entry()`; `tx.send` is non-blocking,
+  non-async, and never re-enters the map, so firing under the shard lock
+  cannot deadlock and keeps global event order in lock-step with global
+  commit order. Pinned by `concurrent_set_fires_no_duplicate_adjacent_events`
+  (4 writers toggling one entity A/B; asserts no two consecutive fired
+  events carry an identical `new_state` — impossible under correct
+  serialisation; a probe observed ~93k such duplicate-adjacent events across
+  200 trials on the racy code, zero on the fix).
+- **HC-EID-LEN-01 (unbounded `entity_id` — memory-DoS at the REST boundary).
+  FIXED.** `homecore-api/src/rest.rs` parses untrusted path segments
+  straight through `EntityId::parse`; with no length cap, an
+  otherwise-valid id (`a.` + many MB of `[a-z0-9_]`) was accepted and a
+  `POST /api/states/<giant>` would persist it into the DashMap state store
+  (permanent growth across distinct ids). **Fix:** reject ids longer than
+  `MAX_ENTITY_ID_LEN` (255, HA-compatible) up front in `parse()`, before any
+  per-char scan, with a new `EntityIdError::TooLong`; fail-closed at the
+  boundary type protects every caller. Pinned by `entity_id_length_boundary`
+  (exactly-MAX accepted, MAX+1 and a 4 MiB id rejected — fails on old code).
+- **HC-SVC-PANIC-01 (service-handler panic not isolated). HARDENED.**
+  `ServiceRegistry::call` already ran handlers outside the registry lock (no
+  `RwLock` poisoning, no blocking of other callers — clean), but a
+  panicking handler unwound through `call()` into the caller's task. **Fix:**
+  wrap the handler future in `AssertUnwindSafe` + `catch_unwind`, converting
+  a panic to `ServiceError::HandlerPanicked`; the registry stays fully
+  usable. Pinned by `panicking_handler_is_isolated_and_registry_survives`.
+
+**Dimensions confirmed clean (with evidence):**
+
+- **Event-bus bounds / lag (same class as the homecore-api WS lag-DoS).**
+  Both `StateMachine` and `EventBus` use bounded `tokio::sync::broadcast`
+  (capacity 4,096). A slow subscriber gets a recoverable `Lagged(n)`
+  (drop-oldest + re-sync); `fire_*` is non-blocking and **never waits on
+  slow receivers**, so a lagging subscriber cannot block the publisher, grow
+  the channel without bound, or take down a fast subscriber. Evidenced by
+  `slow_subscriber_does_not_block_publisher_or_kill_the_bus` (fire 3×
+  capacity at an idle subscriber; publisher unblocked, bus stays live).
+- **Lock ordering / lock-across-await (deadlock).** No code path holds two
+  of `{state DashMap, registry RwLock, service RwLock}` simultaneously, so
+  no inconsistent-ordering deadlock can exist. Every `tokio::sync::RwLock`
+  guard in `registry.rs`/`service.rs` is used in a single synchronous
+  statement and dropped before any `.await`; `call` explicitly scopes the
+  read guard out before awaiting the handler. The only guard held across a
+  send is the DashMap shard lock in `set`, across a synchronous
+  (non-await) broadcast send — safe.
+- **Panic-on-input.** No reachable `unwrap`/`expect`/index in non-test code
+  beyond the safe `send().unwrap_or(0)` and the dead-but-harmless
+  `split_once(...).unwrap_or(...)` fallbacks on already-validated ids.
+
+`cargo test -p homecore --no-default-features`: **20 → 24 passed, 0 failed**
+(+4 pins). Workspace green; Python deterministic proof unchanged
+(`f8e76f21…46f7a`, bit-exact — `homecore` is off the signal proof path).

+## 8a. Security review (beyond-SOTA sweep, post ADR-154–159)
+
+A focused security review of `homecore-automation` (the execution/eval surface — triggers → conditions → actions, with templates) was run after the ADR-154–159 sweep, applying the same rigor that the sibling engine/bfld/calibration/vitals/geo reviews used. **Two real DoS findings, each pinned by a fails-on-old test; the condition-bypass, fail-closed-parsing, and action-authorization dimensions were probed and found clean.**
+
+- **HC-SEC-01 (template-injection / unbounded-expansion DoS, HIGH) — FIXED.** A `template:` condition / `value_template` is user automation config, and was rendered with MiniJinja's defaults: **no instruction budget, no output cap**. A single condition such as `{% for i in range(5000) %}{% for j in range(5000) %}xxxx{% endfor %}{% endfor %}` rendered a **100 MB string over ~11 s on one render call** (measured) — a CPU/memory denial of service (the bfld-class "unbounded expansion"; MiniJinja's per-call `range()` 10k cap does **not** stop nested loops). **Fix:** enable MiniJinja's `fuel` feature and set a per-render budget (`set_fuel(Some(1_000_000))`) so a nested loop burns one unit per iteration — the attack now fails fast (~90 ms) with "engine ran out of fuel"; plus a 64 KiB source-length cap rejecting pathological sources before compilation. Legitimate HA templates (a few dozen instructions) are unaffected. Pinned by `nested_loop_template_is_bounded_not_unbounded_dos`, `single_huge_repeat_template_is_bounded`, `oversized_template_source_is_rejected` (all fail-on-old: unbounded render / no rejection), and `legitimate_template_still_renders_within_fuel` (no regression).
+- **HC-SEC-02 (panic-on-config DoS, MEDIUM) — FIXED.** `Action::Delay { seconds }` and `Action::WaitForTrigger { timeout_seconds }` fed the user-supplied float straight into `Duration::from_secs_f64`, which **panics** on negative, NaN, infinite, or overflowing inputs — all reachable from a crafted (or typo'd) YAML (`delay: {seconds: -1}`, `.nan`, `.inf`, `1e308`). One hostile config aborts the spawned automation run task with a panic (measured: "cannot convert float seconds to Duration: value is negative"). **Fix:** a `safe_duration_from_secs` guard that saturates instead of panicking (NaN/±inf/negative → `Duration::ZERO`, matching HA's lenient "non-positive delay = no delay"; absurdly large → clamped to ~100 years). Pinned by `delay_negative_seconds_does_not_panic`, `delay_nan_seconds_does_not_panic`, `delay_infinite_seconds_does_not_panic`, `wait_for_trigger_negative_timeout_does_not_panic`, `safe_duration_saturates_hostile_values` (incl. overflow clamp).
+
+**Dimensions confirmed clean (with evidence):**
+- **Condition bypass / fail-closed eval** — a `Condition::Template` whose render errors evaluates to `false` (`condition.rs` `Err(_) => false`), and a `Choose` branch condition that fails to deserialize is treated as **non-matching** (the branch is skipped), not silently passing (`action.rs` `ChoiceBranch::matches` `Err(_) => return false`). Both fail **closed** (do-not-run), confirmed by the existing `choose_*` tests and template-false-blocks-action behavioral test. No true-by-default-on-parse-error path found.
+- **Re-entrancy / livelock (DoS)** — run-mode machinery is bounded and tested: `Single`/`IgnoreFirst` re-entrancy guard, `Restart` cancel-and-replace, `Queued` FIFO serialization, and `max: N` semaphore cap (ADR-162; `restart_mode_cancels_prior_run`, `queued_mode_runs_sequentially_not_concurrently`, `max_two_caps_concurrency_at_two`, `single_mode_does_not_double_fire_on_rapid_triggers`). A self-triggering automation does not livelock the engine — each fire is bounded by its run-mode.
+- **Action authorization** — templates are read-only sandboxed (`states`/`state_attr`/`is_state`/`now` globals; no service-call or state-set global is exposed to template scope), so a template cannot escalate into an action. Service authorization itself is enforced at the `homecore` service-registry boundary (out of this crate's scope); no gap found in what the automation crate enforces.
+- **Panic-on-config (parse)** — `serde_yaml`/`serde_json` deserialization returns structured `AutomationError` (no `unwrap`/`expect`/index reachable from a crafted config in the eval/exec path); the only remaining panic surface was the `from_secs_f64` path fixed as HC-SEC-02.
+
+Validation: `cargo test -p homecore-automation --no-default-features` → 54 passed / 0 failed (+14 over baseline). Python deterministic proof unchanged (homecore-automation is off the signal-processing proof path).

+
+## 1. Context
+
+HOMECORE (ADR-126 through ADR-134) is the native Rust + WASM + TypeScript port of Home Assistant running as the hub on the Cognitum v0 Appliance. As of P2, the state machine ([ADR-127](ADR-127-homecore-state-machine-rust.md)), API ([ADR-130](ADR-130-homecore-rest-websocket-api.md)), and COG runtime ([ADR-128](ADR-128-homecore-integration-plugin-system.md)) are in place. What is missing is a first-class dashboard UI that operators, integrators, and residents can use to manage the full two-tier hardware stack that HOMECORE coordinates.
+
+### 1.1 The two-tier hardware model this UI must represent
+
+This is the most important architectural constraint the UI must carry through every panel:
+
+- **Cognitum SEED** — a Pi Zero 2 W-based edge node. It has its own RVF vector store (8-dim, content-addressed, with kNN queries), Ed25519 witness chain, SHA-256 ingest audit trail, onboard environmental sensors (BME280 temperature/humidity/pressure, PIR motion, reed switch, ADS1115 4-channel ADC, vibration), 13 drift detectors, an MCP proxy (114 tools, JSON-RPC 2.0, default-deny policy), 98 HTTPS API endpoints, and epoch-based swarm sync for multi-SEED deployments. SEEDs sit close to the ESP32 sensing nodes and receive feature vectors from them at 1 Hz. Multiple SEEDs can form a peer mesh. **This is the sensing and memory tier.**
+- **Cognitum v0 Appliance** — a Pi 5 + Hailo-10H hub, running at `:9000`. It hosts the COG runtime (`/var/lib/cognitum/apps/`), the HOMECORE state machine and event bus, the calibration service, `ruview-mcp-brain:9876`, `cognitum-rvf-agent:9004`, `ruvector-hailo-worker:50051`, and acts as the fleet coordinator for multi-room correlation and federated training. The Appliance is where HOMECORE runs, and it is what the dashboard user is sitting in front of. **This is the computation and orchestration tier.**
+
+SEEDs are **subordinate nodes that the Appliance supervises** — they are not peers. The UI navigation hierarchy must reflect this: the Appliance is the root, SEEDs are children, ESP32 nodes are leaves.
+
+### 1.2 What the UI is not
+
+HOMECORE-UI is **not** a re-skin of the existing Cognitum Cog Store. It is a full operational dashboard that **extends** the Cognitum platform's shell — the Cog Store, API Explorer, and Guide already exist and must remain intact, with the HOMECORE dashboard added as a first-class navigation section alongside them.
+
+---
+
+## 2. Decision
+
+Build HOMECORE-UI as a **complete** TypeScript + Rust→WASM frontend (per this ADR's §3 and the HOMECORE-127…134 family) that:
+
+1. Lives at `http://cognitum-v0:9000/homecore` (or as a dedicated nav item in the Cognitum Appliance shell).
+2. Is visually and stylistically seamless with the existing Cognitum platform — same dark theme, same design tokens, same component patterns as `https://seed.cognitum.one/store`.
+3. Drives the HOMECORE REST + WebSocket API ([ADR-130](ADR-130-homecore-rest-websocket-api.md)) and the calibration HTTP API ([ADR-151](ADR-151-room-calibration-specialist-training.md)) for all data.
+4. Updates in real-time via the homecore `subscribe_events` WebSocket channel. **The UI must never poll for entity state.**
+
+**This is a decision to deliver the complete operational dashboard — every panel in §4.1 through §4.10, every navigation section in §5, fully wired to live data — not a design-system scaffold or a partial first cut.** A static layout shell with placeholder data is explicitly **out of scope as a deliverable**: the design system (§3) is a means to the complete UI, not an end in itself. The acceptance bar for this ADR is that an operator can drive the full two-tier stack — fleet, entities, rooms, COGs, calibration, events, audit, and settings — from the dashboard, against real APIs, with no panel left as a stub.
+
+### 2.1 `homecore-server` is the single backend-for-frontend (BFF) gateway
+
+The data the dashboard needs is spread across **three backend tiers that are not one process**: (a) `homecore-api` (`/api/*` REST + `/api/websocket`, mounted in `homecore-server`); (b) the **calibration API** (`/api/v1/*`, served by a *separate* binary — `wifi-densepose calibrate-serve` / `wifi-densepose-sensing-server`); and (c) the **SEED device tier + appliance daemons** (RVF vector store, witness chain, onboard sensors, reflex rules, COG supervisor, federation), which are physically separate HTTPS services on the SEED nodes and the appliance.
+
+The browser must talk to **exactly one origin.** Therefore `homecore-server` is promoted to the **single BFF / API gateway** for HOMECORE-UI: it serves the static assets at `/homecore`, serves `homecore-api` at `/api/*`, and **adds a new `/api/homecore/*` namespace** that proxies and aggregates the calibration API and the SEED/appliance tiers server-side. The UI only ever issues same-origin requests; cross-service auth (SEED bearer tokens, calibration tokens) is held by the gateway and **never exposed to the browser**. This collapses the CORS/multi-port problem and gives one place to enforce the long-lived-access-token auth (§4.10).
+
+### 2.2 No mock data in production
+
+The in-browser mock layer that the first UI cut shipped behind DEMO banners (§7.1, prior revision) is **demoted to a dev-only fixture** gated behind an explicit `?demo=1` / `HOMECORE_UI_DEMO=1` flag. The production build wires **every** panel to a real gateway endpoint. The full endpoint contract and the backend work each panel needs are specified in **§11**; the staged path to get there is **§12**. A panel may show an empty/typed-error state when its upstream is down, but it must never silently render fabricated data.
+
+---
+
+## 3. Design system — Cognitum platform conventions
+
+The implementor **must study `https://seed.cognitum.one/store` as the definitive design reference before writing a single line of CSS.** The existing platform's design tokens, extracted from production, are:
+
+### 3.1 Colour palette (CSS custom properties)
+
+| Token | Value | Role |
+|---|---|---|
+| `--bg` | `#0a0e1a` | page background (very dark navy) |
+| `--bg2` | `#111627` | secondary background / nav strip |
+| `--card` | `#171d30` | card / panel surface |
+| `--card-h` | `#1e2540` | card hover state |
+| `--border` | `#252d45` | all border strokes (≈0.67px, subtle) |
+| `--t1` | `#e0e4f0` | primary text (near-white) |
+| `--t2` | `#8890a8` | secondary / muted text |
+| `--t3` | `#505872` | tertiary / disabled text |
+| `--cyan` | `#4ecdc4` | primary action colour (Install buttons, live indicators, accents) |
+| `--cyan-d` | `rgba(78,205,196,0.15)` | cyan tint background for status badges |
+| `--green` | `#6bcb77` | success / online / healthy states |
+| `--green-d` | `rgba(107,203,119,0.15)` | green tint background |
+| `--amber` | `#d4a574` | warning / stale / degraded states |
+| `--amber-d` | `rgba(212,165,116,0.15)` | amber tint background |
+| `--red` | `#e06060` | error / offline / veto states |
+| `--red-d` | `rgba(224,96,96,0.15)` | red tint background |
+| `--purple` | `#a78bfa` | informational / epoch / chain indicators |
+| `--purple-d` | `rgba(167,139,250,0.15)` | purple tint background |
+| `--r` | `10px` | standard border radius on all cards and panels |
+
+### 3.2 Typography
+
+- `--font`: `'Segoe UI', system-ui, -apple-system, sans-serif` — all body and heading text.
+- `--mono`: `'Cascadia Code', 'Fira Code', Consolas, monospace` — all entity IDs, API endpoints, hex values, JSON payloads, COG binary hashes.
+
+### 3.3 Component patterns (from the live Cog Store and API Explorer)
+
+- **Cards**: `background: var(--card)`, `border: 0.67px solid var(--border)`, `border-radius: var(--r)`, `padding: 24px`.
+- **Category pills / status badges**: small `border-radius: 4–6px`, uppercase text, coloured background tint (e.g. `background: var(--cyan-d); color: var(--cyan)` for `RUNNING`; `background: var(--amber-d); color: var(--amber)` for `STALE`).
+- **Primary action buttons**: `background: var(--cyan)`, `color: var(--bg)`, no border — matching the existing "Install" button style exactly.
+- **Secondary / ghost buttons**: transparent background, `border: 1px solid var(--border)`, `color: var(--t1)` — matching the existing "Details" button style.
+- **Nav strip**: `background: var(--bg2)`, text items in `--t2`, active item highlighted in `--cyan` with a bottom underline.
+- **Featured card gradient borders**: top-edge linear gradient from `var(--cyan)` to `var(--purple)` — replicate for HOMECORE section headers.
+- **Live metric cards** (API Explorer status page): icon + large numeric value in `--cyan` or `--green`, label in `--t2` below, on a `var(--card)` background.
+- **Method badge pills** on the API Explorer (`GET` in green, `POST` in amber, `AUTH` in purple) — reuse this same pill system for COG status indicators.
+
+The implementor **must not introduce new colours, typefaces, or border radii.** Every component should feel like it was built by the same team that built the Cog Store and the API Explorer. A user navigating from the Cog Store into the HOMECORE dashboard should not notice a visual seam.
+
+---
+
+## 4. UI sections — required panels
+
+### 4.1 System Dashboard (the "home screen")
+
+The always-visible overview panel. Modelled on the API Explorer's live metric cards. All values update in real-time.
+
+- **v0 Appliance health strip** — reuse the exact metric-card pattern from `seed.cognitum.one/status`: one card each for CPU %, RAM usage, Hailo-10H inference load (% utilisation), Hailo temperature, uptime, and the running services (`ruview-mcp-brain:9876`, `cognitum-rvf-agent:9004`, `ruvector-hailo-worker:50051`). Values in `--cyan`, labels in `--t2`. This strip is always at the top — it represents the machine the user is looking at.
+- **SEED Fleet overview** — a grid of SEED node cards (one per paired SEED) on the `var(--card)` surface with `var(--border)`. Each card shows: online/offline status pill (green/red), firmware version, epoch number, current vector count, last ingest timestamp, and witness-chain validity badge. A collapsed row shows the SEED's 5 onboard sensors in summary (PIR: yes/no, door: open/closed, temperature from BME280). Offline SEEDs render the entire card with a `--red-d` background tint. Clicking a SEED card navigates to the SEED Detail view (§4.2).
+- **ESP32 Node summary** — count of active ESP32 nodes per SEED, current frame rate (target: 100 Hz CSI + 1 Hz feature vectors), and a compact warning list for nodes with known issues (presence_score normalisation anomaly, stale firmware version).
+- **COG Runtime status row** — a horizontal strip of status pills for each installed COG on the v0 Appliance. Pill colours follow the existing badge convention: `--green-d`/`--green` for running, `--red-d`/`--red` for failed, `--t3`/`--t2` for stopped. COG name in `--mono`. Clicking a pill navigates to COG Management (§4.6).
+- **Event Bus activity indicator** — a small real-time sparkline showing the homecore broadcast channel event rate (events/sec). Indicate channel lag if a subscriber is falling behind the 4,096-event capacity.
+
+### 4.2 SEED Detail View (per-SEED drill-down)
+
+Accessible from the fleet grid. Full-page panel for a single SEED node, using the card + section-header pattern from the Cog Store's detail views.
+
+- **SEED identity header** — `device_id` in `--mono`, firmware version, paired status in green, USB vs WiFi connection mode. A section-header gradient border (cyan → purple, matching the featured card style) visually separates this from Appliance content.
+- **Vector Store panel** — current vector count, dimension (8), last kNN query latency, current epoch number, a small sparkline of ingest rate over the last hour, and a storage budget bar showing usage against the 100K working-set target. A "Compact now" button (`POST /api/v1/store/compact`) in ghost style. When usage exceeds 80%, the bar renders in `--amber`.
+- **Witness Chain panel** — chain length (SHA-256 entries), last verification timestamp, a one-click "Verify chain" button (`POST /api/v1/witness/verify`), and an "Export attestation bundle" button for regulated deployments. The Ed25519 custody attestation (device-bound keypair, epoch + vector count + witness head) renders here. Chain length in `--purple`, following the existing epoch/chain colour convention.
+- **Onboard Sensors panel** — live readings from all 5 sensors in individual sub-cards: BME280 (temperature °C, humidity %, pressure hPa), PIR (motion boolean with last-triggered timestamp), reed switch (open/closed with last-changed timestamp), ADS1115 (4 analog channels with configurable labels), vibration (boolean with last-triggered). These are ground-truth validators against CSI readings and are critical for diagnosing false positives in the mixture-of-specialists. Sensor values in `--cyan`; sensor names in `--t2`.
+- **Reflex Rules panel** — the 3 pre-configured rules with current state: `fragility_alarm` (threshold 0.3 → relay actuator), `drift_cutoff` (threshold 1.0), `hd_anomaly_indicator` (threshold 200 → PWM brightness). Show last-fired time for each. The `fragility_alarm` threshold is the most commonly adjusted field and should be editable inline. Rules that have recently fired render with a `--amber-d` background tint.
+- **Cognitive Analysis panel** — boundary fragility score (0.0–1.0, from Stoer-Wagner min-cut on the kNN graph) rendered as a progress bar: green below 0.3, amber 0.3–0.6, red above 0.6. High fragility (>0.3) indicates a regime change in the environment and should be visually prominent. Temporal coherence phase boundaries shown as a labelled timeline of detected environment state transitions. kNN graph rebuild cadence indicator (every 10 s).
+- **Ingest pipeline status** — which ESP32 nodes feed this SEED, the packet type each is sending (`0xC5110003` native feature vectors vs `0xC5110002` vitals fallback path — distinguished visually since native is preferred), current ingest batch size, flush interval, and bridge path topology (direct vs host-laptop hop). The bridge-hop warning (known architectural limitation) renders in `--amber` since it adds a network hop.
+
+### 4.3 SEED Fleet Map (multi-SEED topology)
+
+For deployments with more than one SEED, a topology view showing the mesh:
+
+- **Node hierarchy diagram** — v0 Appliance at root, SEEDs as second tier (grouped by room/zone), ESP32 nodes as leaves under each SEED. Lines represent active data flows. ESP-NOW mesh sync links between SEEDs shown as dashed lines. Connection health shown via line colour (green/amber/red). All labels in `--mono`.
+- **Cross-SEED event deduplication indicator** — for events that span multiple SEEDs (one fall detected by two rooms; one occupant tracked through room A → hallway → room B), show a fusion badge indicating how many SEEDs contributed to the composite event.
+- **Federation config** ([ADR-105](ADR-105-federated-csi-training.md)) — federated-learning round coordinator role (which SEED is the round coordinator), current round number, K healthy nodes selected, delta exchange status. **Model deltas only — never raw CSI** is a design invariant that must be labelled explicitly in the UI.
+
+### 4.4 Entity & State Browser
+
+The homecore state machine (`DashMap<EntityId, Arc<State>>`) is the authoritative source of truth. Every COG running on the v0 Appliance contributes entities.
+
+- **Entity list by domain** — grouped by the `domain.` prefix of `EntityId`, using collapsible section headers. The 21 entities per ESP32 node (11 raw + 10 semantic primitives from `cog-ha-matter`) are the most important set. For each entity: current state string (in `--t1`), last-changed timestamp (in `--t3`), attribute map as collapsible JSON in `--mono`, and the Context (`user_id` + `parent_id` causality chain, critical for care/audit deployments). Entity IDs always in `--mono`.
+- **SEED provenance badge** — each entity carries a small badge showing its data lineage: which ESP32 node → which SEED → which COG → homecore state machine. This trace is invaluable for debugging false positives and is a **first-class UI element, not a collapsed detail.**
+- **Domain filter + semantic search** — filter by domain prefix and, once [ADR-132](ADR-132-homecore-recorder-history-semantic-search.md) (homecore-recorder) lands, ruvector-backed semantic search: "when did the living room anomaly score last correlate with a door-open event?" A keyword filter across entity IDs and attribute keys ships in the initial release regardless of [ADR-132](ADR-132-homecore-recorder-history-semantic-search.md) status, given entity density; the semantic search layers on top once the recorder lands.
+- **Real-time WebSocket feed** — entity states update live via the homecore `subscribe_events` WebSocket command ([ADR-130](ADR-130-homecore-rest-websocket-api.md)). The UI must never poll. Show a broadcast-channel lag indicator; warn visually if the subscriber is falling behind the 4,096-event channel capacity.
+- **StateChanged detail panel** — clicking any entity opens a slide-over panel showing the full `StateChangedEvent`: `old_state`, `new_state`, `context.id`, `context.user_id`, and the `context.parent_id` chain rendered as a breadcrumb trail.
+
+### 4.5 RoomState / Sensing Panel
+
+Surfaces the mixture-of-specialists output from the calibration service — the highest-level per-room sensing result. Data comes from `GET /api/v1/room/state?bank=<room_id>` on the v0 Appliance.
+
+- **Per-room cards** — one card per `room_id` on the `var(--card)` surface. Each card shows live `RoomState` JSON fields as sub-rows: presence (occupied/absent chip in green/red with confidence bar), posture (standing/sitting/lying chip with confidence), breathing BPM (numeric in `--cyan` with range indicator 6–30), heart rate BPM (numeric in `--cyan` with range indicator 40–120), restlessness score (0–1 progress bar), and anomaly score (0–1 with normal/anomalous label, bar turns red above a configurable threshold).
+- **STALE warning** — when `stale: true` (the specialist bank was trained against a different baseline), render the entire room card with a `--amber-d` background tint and a prominent amber banner reading "Bank stale — baseline has changed" with a direct "Recalibrate room" link into the calibration wizard (§4.7). This is the most common real-world failure mode and **must never be subtle.**
+- **VETO indicator** — when `vetoed: true` (anomaly veto suppressed vitals/posture because the window was physically implausible), render the affected specialist slots in `--red` with a "Veto active" label. Values suppressed by veto **must not render as zeros** — they must render as explicitly withheld.
+- **Null specialist placeholders** — specialists not yet trained (`null` in the specialist bank) render as "Not trained" placeholders in `--t3` with a small "Calibrate to enable" prompt in ghost style. They are **not** errors.
+- **Confidence bars** — each specialist output has a confidence float, shown as a small inline bar (`--cyan` fill) next to the reading. Low confidence (< 0.4) renders the bar in `--amber`.
+- **Multi-SEED fusion indicator** — for rooms served by multiple SEEDs, show a small badge indicating how many SEED nodes contributed to the `MultiNodeMixture` for this room's reading.
+
+### 4.6 v0 Appliance COG Management
+
+The v0 Appliance hosts COGs at `/var/lib/cognitum/apps/`. This panel is the operational companion to the existing Cog Store (`seed.cognitum.one/store`). It must match the Cog Store's visual conventions precisely — same card layout, same category pills, same install/detail button pair — because operators will move between the two surfaces.
+
+- **Installed COGs list** — for each COG: `id` and `version` in `--mono`, architecture badge (`arm`/`hailo10` etc., category-pill pattern), status pill (running/stopped/failed/updating in green/grey/red/amber), `binary_sha256` verified badge (Ed25519 signature verification shown as a shield icon in `--green` or `--red`), and PID from the pid file. Actions: start, stop, restart (ghost style), and view `output.log` / `error.log` in a monospace drawer using `--mono`. Edit `config.json` inline with syntax highlighting.
+- **COG Store / App Registry** — browsable `app-registry.json` listing. This panel should visually mirror `seed.cognitum.one/store` as closely as possible — same featured-card hero layout, same icon + title + description + category pill + action button structure. One-click install downloads the binary from GCS, verifies `binary_sha256` + `binary_signature`, writes the manifest, and starts the COG. Show which new homecore entities will appear in the state machine after install, as a preview list before confirming.
+- **OTA Updates** — a badge count on installed COGs with available updates, matching the "Installed (N)" tab badge convention from the existing Cog Store. Show a diff panel (version change, new entities, config schema changes) before confirming the update.
+- **Hailo HEF status** — for COGs with `arch: hailo10`: loaded HEF files on the Hailo-10H, current inference throughput, and `ruvector-hailo-worker:50051` connection status. The RF Foundation Encoder ([ADR-150](ADR-150-rf-foundation-encoder.md)) and neural pose head display here once available.
+
+### 4.7 Calibration Wizard
+
+The full baseline → enroll → train → verify pipeline runs via HTTP against the v0 Appliance ([ADR-151](ADR-151-room-calibration-specialist-training.md)). This is a multi-step guided flow — not a raw API panel. Use a stepped wizard layout with a progress indicator at the top (steps 1–5 as numbered pills, active step in `--cyan`, completed in `--green`, pending in `--t3`).
+
+- **Step 1 — Select room and SEED** — enter a `room_id` name (validated against `[A-Za-z0-9_-]{1,64}`) and select which SEED(s) and ESP32 nodes serve this room from a dropdown populated from the live fleet. Show current CSI ingest health for the selected nodes inline — if frames are not arriving at the expected rate, display an amber warning **before** allowing the operator to proceed. A broken ingest pipeline will silently fail calibration.
+- **Step 2 — Baseline capture** — `POST /api/v1/calibration/start`. A large full-width animated progress bar (cyan fill) reads from `GET /api/v1/calibration/status`: frames recorded vs target, ETA in seconds, `z_median` value. If `motion_flagged` is true, overlay an amber banner: "Room must be empty — movement detected." The baseline UUID produced here is the anchor for all future STALE detection for this room — display it in `--mono` once complete so operators can record it.
+- **Step 3 — Anchor enrollment** — the 8 anchor labels in enforced order: `empty`, `stand_still`, `sit`, `lie_down`, `breathe_slow`, `breathe_normal`, `small_move`, `sleep_posture`. For each: a human-readable instruction with an illustration, a countdown timer rendered as a circular progress ring in `--cyan`, and an immediate quality-gate result (accepted in green, retry in amber with a reason string). Drive via `POST /api/v1/enroll/anchor` + `GET /api/v1/enroll/status`. After each accepted anchor, show the extracted feature values (mean, variance, breathing_score, heart_score) in a small `--mono` data row so operators can sanity-check the capture. Show overall progress as "N / 8 anchors accepted."
+- **Step 4 — Train** — a single `POST /api/v1/room/train` call. Show the 6 specialist results as a checklist: presence (threshold + occupied_var), posture (prototype count), breathing (min_score), heartbeat (min_score), restlessness (calm/active motion values), anomaly (prototype count + scale). Specialists that returned non-null render in `--green`. Null specialists (insufficient anchor data) render in `--amber` with a "Re-enroll missing anchors" prompt linking back to Step 3 for the specific missing labels.
+- **Step 5 — Verify live** — display the live `RoomState` for the just-trained room using the same per-room card layout as §4.5. Prompt the operator to stand in the room and verify presence is detected, try sitting/lying to confirm posture, and breathe normally to confirm vitals are in plausible range. A "Confirm and save" button (cyan, primary) closes the wizard; a "Something's wrong — re-enroll" button (ghost) loops back to Step 3.
+
+### 4.8 Event Bus & Automation Feed
+
+- **Live event stream panel** — a virtualized scrolling list of `SystemEvent` variants (`StateChanged`, `EntityRegistered`, `ConfigReloaded`) and notable `DomainEvent`s from the homecore Tokio broadcast channel. Each row shows: event-type pill (coloured by variant), `entity_id` in `--mono`, old state → new state arrow, timestamp, and `context.user_id`. The stream is filterable by entity domain, event type, or source SEED/COG. The filter bar uses the same search-input style as the Cog Store's search field.
+- **Context causality breadcrumb** — expanding any event row shows the full Context chain (`context.id` → `parent_id` → `grandparent_id`) as a breadcrumb trail in `--mono`. This is how automation loops become visible without any separate debugging tool.
+- **Automation builder** ([ADR-129](ADR-129-homecore-automation-engine.md) scope) — a trigger → condition → action editor on the card surface. The most important RuView-specific trigger types to support are: `state_changed` on `RoomState` entities with a threshold expression (e.g. `anomaly.value > 0.8`), SEED reflex-rule firing events (`fragility_alarm`, `hd_anomaly_indicator`), and custom `domain_event` topics. Actions include calling services in the homecore service registry and firing domain events. The condition expression editor uses `--mono`.
+
+### 4.9 Witness / Audit Log
+
+- **Unified witness timeline** — a chronological merged view of events from both tiers: the SEED's SHA-256 ingest chain (every RVF store write attested) and homecore's Ed25519 state-transition chain (biometric crossings, BFLD identity-risk elevations). Each row: `entity_id` in `--mono`, old/new state, timestamp, source SEED `device_id`, signing key fingerprint (first 8 chars in `--mono`). Pagination uses the same "Showing X–Y of Z" convention from the Cog Store's cog grid.
+- **Privacy mode banner** — a persistent top-of-panel banner showing current privacy mode: `--green-d`/green text for full-publish mode; `--amber-d`/amber text for audit-only mode (SHA-256 digests on-SEED only, no MQTT state messages). Show the per-SEED privacy mode state, since SEEDs can be individually configured. Toggling privacy mode is a high-stakes action — require an explicit "Confirm" step with a summary of what will change.
+- **Export bundle** — an "Export attestation bundle" button (ghost) that packages the SEED witness chain + homecore Ed25519 chain as a downloadable archive for regulated-deployment (care home, hotel, shared office) compliance handoff.
+
+### 4.10 Settings & Integration Config
+
+- **SEED fleet management** — add, remove, and reprovision SEEDs. Show the USB-only pairing requirement prominently (the pairing window only opens via `169.254.42.1`, not WiFi — a security invariant). Per-SEED: `device_id` in `--mono`, firmware version, bearer token status, and a "Rotate token" action (ghost) that walks the operator through the secure token rotation flow.
+- **ESP32 node provisioning** — per-node NVS config display (target IP, target port, node_id), last-seen firmware version, and a link to the provisioning script. The `node_id` → room/zone assignment is editable here and persists to the room calibration system's `room_id` mapping.
+- **MQTT / cog-ha-matter config** ([ADR-116](ADR-116-cog-ha-matter-seed.md)) — broker URL, credentials (masked), MQTT topic prefix, mDNS advertisement status (`_ruview-ha._tcp`), and a live connection indicator (green dot for connected, red for unreachable). The 21 HA-DISCO entities per node are listed here with their `via_device` assignments showing which SEED they belong to in HA's device registry.
+- **Long-lived access tokens** — for homecore-api companion-app connections (HA 2025.1 wire-compat, [ADR-130](ADR-130-homecore-rest-websocket-api.md)). Token creation, last-used timestamp, and revocation. The HA companion-app pairing QR-code flow surfaces here.
+- **Federation config** — for multi-SEED deployments: ESP-NOW mesh sync status, cross-SEED epoch alignment values, and federated-learning round settings (coordinator SEED, round cadence, Krum aggregation parameters per [ADR-105](ADR-105-federated-csi-training.md)). The design invariant **"model deltas only, never raw CSI"** must be labelled explicitly in this panel.
+
+---
+
+## 5. Navigation structure
+
+HOMECORE-UI must integrate into the existing Cognitum Appliance nav shell. The top nav should read:
+
+```
+Framework | Guide | Cog Store | HOMECORE | Status
+```
+
+— inserting **HOMECORE** as a first-class nav item between the existing "Cog Store" and "Status" entries, using the same nav-item style (text in `--t2`, active state in `--cyan` with bottom underline).
+
+Within the HOMECORE section, a left sidebar (or top sub-nav on narrow viewports) provides section navigation:
+
+```
+Dashboard | SEED Fleet | Entities | Rooms | COGs | Calibration | Events | Audit | Settings
+```
+
+The COG Store panel within HOMECORE (§4.6) links out to `seed.cognitum.one/store` for the full catalog view, ensuring the existing Cog Store remains the canonical browsing experience.
+
+---
+
+## 6. Key UX invariants
+
+These must be maintained across every panel:
+
+1. **Always make the tier origin of any data explicit.** A `RoomState` reading traces to an ESP32 node → SEED → COG → v0 Appliance state machine. The provenance badge (§4.4) must appear wherever entity states are displayed.
+2. **The `stale` and `vetoed` flags from `RoomState` and the kNN fragility score from SEED cognitive analysis are meaningful diagnostic signals** — they must never be silently hidden, styled grey-on-grey, or collapsed behind an expand toggle. They represent system health operators need to act on.
+3. **Values that are `null` because a specialist has not been trained must be visually distinct from values that are unavailable due to an error.** The distinction is operationally important: `null` means "calibrate to enable," unavailable means "investigate."
+4. **All entity IDs, hashes, API endpoints, binary signatures, device UUIDs, and JSON payloads must use `--mono` font.** This is already the convention in the API Explorer and must be consistent throughout HOMECORE-UI.
+5. **The v0 Appliance Hailo HAT is a separate subsystem from the SEED's edge compute.** Inference results tagged as Hailo-sourced (COGs with `arch: hailo10`) must be visually distinguished from results from CPU-only COGs (`arch: arm`) so operators can triage hardware-specific failures.
+
+---
+
+## 7. Scope — complete UI delivery
+
+The deliverable is the **entire** dashboard. Every panel below ships fully implemented and wired to its live data source — there is no scaffold-only milestone and no panel left as a placeholder. The table records each panel's authoritative backing API so the build can proceed in whatever order best fits the dependency graph; it is a dependency map, **not** a sequence of partial releases.
+
+| Panel | Section | Backing API / source |
+|---|---|---|
+| System Dashboard | §4.1 | [ADR-130](ADR-130-homecore-rest-websocket-api.md) WebSocket + appliance health endpoints |
+| SEED Detail View | §4.2 | SEED HTTPS API (vector store, witness, sensors, reflex, cognitive analysis) |
+| SEED Fleet Map | §4.3 | fleet topology + federation ([ADR-105](ADR-105-federated-csi-training.md)) |
+| Entity & State Browser | §4.4 | [ADR-127](ADR-127-homecore-state-machine-rust.md) state machine via [ADR-130](ADR-130-homecore-rest-websocket-api.md) `subscribe_events`; semantic search via [ADR-132](ADR-132-homecore-recorder-history-semantic-search.md) |
+| RoomState / Sensing | §4.5 | [ADR-151](ADR-151-room-calibration-specialist-training.md) `GET /api/v1/room/state` |
+| COG Management | §4.6 | [ADR-128](ADR-128-homecore-integration-plugin-system.md) plugin runtime + [ADR-100](ADR-100-cog-packaging-specification.md) app registry |
+| Calibration Wizard | §4.7 | [ADR-151](ADR-151-room-calibration-specialist-training.md) calibration HTTP API |
+| Event Bus & Automation | §4.8 | [ADR-130](ADR-130-homecore-rest-websocket-api.md) broadcast channel + [ADR-129](ADR-129-homecore-automation-engine.md) automation engine |
+| Witness / Audit Log | §4.9 | SEED SHA-256 ingest chain + homecore Ed25519 chain |
+| Settings & Integration | §4.10 | SEED provisioning, [ADR-116](ADR-116-cog-ha-matter-seed.md) MQTT/Matter, LLAT, federation |
+
+### 7.1 Build sequencing within the complete deliverable
+
+The complete UI depends on backing services that mature on their own timelines. Each panel is built against the **real gateway endpoint** defined in §11; where the upstream is not yet available the panel renders a typed empty/error state, **not** fabricated data (the dev-only `?demo=1` fixture of §2.2 exists for offline development only and is never the shipped behaviour). Concretely, the hard contract dependencies are: [ADR-130](ADR-130-homecore-rest-websocket-api.md) (REST + WebSocket), [ADR-127](ADR-127-homecore-state-machine-rust.md) (state machine), [ADR-151](ADR-151-room-calibration-specialist-training.md) (calibration), [ADR-128](ADR-128-homecore-integration-plugin-system.md) (plugin runtime), [ADR-129](ADR-129-homecore-automation-engine.md) (automation), [ADR-132](ADR-132-homecore-recorder-history-semantic-search.md) (event history + semantic search), [ADR-116](ADR-116-cog-ha-matter-seed.md) (SEED/Matter), [ADR-069](ADR-069-cognitum-seed-csi-pipeline.md) (SEED ingest), and [ADR-105](ADR-105-federated-csi-training.md) (federation). The keyword entity filter (§4.4) ships immediately; semantic search layers on once [ADR-132](ADR-132-homecore-recorder-history-semantic-search.md) lands. The exact panel→endpoint→upstream map and the new gateway code each requires are §11; the staged delivery is §12.
+
+---
+
+## 8. Consequences
+
+### 8.1 Positive
+
+- Operators, integrators, and residents get a single coherent surface for the full two-tier stack, replacing the need to SSH into SEEDs or hand-craft API calls.
+- The dashboard reuses the proven Cognitum design tokens and component patterns verbatim, so it ships visually consistent with no separate design effort and no perceptible seam between surfaces.
+- Diagnostic signals that today are invisible (`stale`/`vetoed` flags, kNN fragility, provenance lineage, channel lag) become first-class, surfacing the system's most common real-world failure modes directly to operators.
+
+### 8.2 Negative / risks
+
+- The UI hard-depends on the wire-compat guarantees of ADR-130 and the calibration contract of ADR-151; schema drift in either breaks panels silently. Integration tests against every backing contract in §7 are required.
+- Committing to the complete UI in one deliverable is a larger up-front effort and couples the UI's readiness to the maturity of multiple backing services (§7.1, §11). The mitigation is the BFF gateway (§2.1): each panel targets one same-origin endpoint, and the gateway absorbs upstream churn behind a stable contract.
+- Promoting `homecore-server` to a gateway means it now **proxies cross-tier traffic** (calibration API, SEED HTTPS, appliance daemons). This adds a network hop, a place for upstream timeouts/partial failures to surface, and a server-side store of SEED bearer tokens that must be protected (§11.10). Each proxied route needs an explicit timeout + typed error mapping so one slow SEED cannot stall the dashboard.
+- Several panels depend on data that only exists on **real hardware or new daemons** (SEED device tier, appliance host metrics, COG supervisor). Until those upstreams exist the corresponding gateway routes return `503 upstream_unavailable`; this is honest but means the dashboard is only as "live" as the tiers behind it (§11 classifies every endpoint by what it depends on).
+- Faithfully mirroring `seed.cognitum.one/store` couples HOMECORE-UI to the external Cog Store's evolving design; token drift there must be tracked and re-synced.
+- The two-tier mental model (Appliance root, SEED children, ESP32 leaves) must be enforced consistently; any panel that flattens or peers the tiers undermines the core architectural constraint.

+
+## 10. Implementation status
+
+Implemented as a zero-dependency, no-build-step vanilla TS/JS + CSS frontend served by `homecore-server` at `/homecore` (the `rufield-viewer` "Axum + vanilla-JS" pattern). The complete deliverable per §2/§7 — all ten panels, fully rendered, wired to live data where the backing service exists and to a contract-conformant DEMO-flagged mock layer (§7.1) where it does not.
+
+**Location:** `v2/crates/homecore-server/ui/` — `css/tokens.css` (the §3.1 palette, verbatim) + `css/app.css` (§3.3 components); `js/{ui,api,ws,mock,app}.js` (shared helpers, REST client, `subscribe_events` WS client, mock layer, shell+router); `js/panels/*.js` (one module per §4 panel). Mounted via `tower-http` `ServeDir` in `homecore-server::build_app`, gated by `--ui-dir`/`HOMECORE_UI_DIR`.
+
+**Verification:**
+- **Rust** — `#[cfg(test)] mod ui_tests` in `homecore-server/src/main.rs`: 5 integration tests (`tower::oneshot`) covering index, design tokens, all ten panel modules served, API coexistence, and mount-disable. *Written but not compiled in the authoring environment (no Rust toolchain present); run `cargo test -p homecore-server` on a Rust host before merge.*
+- **Frontend** — `ui/` test suite under plain `node` (no npm install): `npm test` → import/export graph verifier (15 modules) + render-smoke (executes every panel against a DOM shim; 21 checks) + interaction suite (live WS patch, ws.js handshake/parse, calibration contract; 3 checks). **24/24 green.**
+- **Benchmark** — `npm run bench`: total bundle **136.8 KB** uncompressed (**~37× smaller** than HA's ~5 MB Lit bundle, the ADR-126 §1.1 foil); slowest panel **1.5 ms/cold-render**.
+
+**Honest scope — current vs. target.** *Earlier cut:* the front-end was complete but only §4.4 Entities was wired to a real backend; the rest rendered from an in-browser mock. *This revision implements the §11 wiring:*
+
+- **Front-end (§11.11) — DONE and verified.** `api.js` rewritten: all data accessors are async and call the §11.2 gateway routes; the mock layer is demoted to a dev-only fixture reachable **only** under `?demo=1` / `HOMECORE_UI_DEMO` (§2.2); every panel `await`s and renders a typed empty/error state on failure (no mock fallback in production). All ten panels converted (3 by hand, 7 via parallel agents). Verified under Node: 5 test files green — import graph, boot, render-smoke (22), interaction (3), **and a new prod-errors suite (13) that runs with demo OFF + gateway unreachable and asserts every panel renders an error state, never mock, never throws** (it caught and fixed a real unhandled-rejection in the events panel).
+- **Gateway (§11.1–§11.6) — IMPLEMENTED, COMPILED, TESTED, RUN.** New `homecore-server/src/gateway.rs` (+`reqwest` dep, +CLI/env flags `--calibration-url`/`--calibration-token`/`--apps-dir`/`--gateway-timeout-ms`, merged into `build_app` via `gateway_router`). Real handlers: `/api/cal/*` reverse-proxy (W2), `GET /api/homecore/rooms` with the §11.3 RoomState adapter (W2), `GET /api/homecore/cogs` supervisor over the apps dir (W4), `GET /api/homecore/appliance` from `/proc` + port probes (W6). SEED-device/appliance-daemon routes (seeds, federation, witness, privacy, settings, automations, events-history, hailo, tokens — W3/W5) return a typed `503 upstream_unavailable` per §11.2. **Verified on Rust 1.89: `cargo test -p homecore-server --no-default-features` = 12/12 pass** (6 gateway + 6 UI mount). **Run live:** `GET /api/homecore/appliance` returns real `/proc` metrics + TCP service probes; unauth → `401`; `cogs` → `[]` with no apps dir; SEED-tier → typed `503`; and against a mock calibration upstream the `/api/cal/*` proxy passes through (`200`) and `GET /api/homecore/rooms` correctly adapts `RoomState` to the UI shape (`breathing`→`breathing_bpm`, `heartbeat:null`→`heart_bpm:null`, injected `anomaly.threshold`/`room_id`, `stale` passthrough). **Live testing caught + fixed one real bug** — a double-`v1` path in the `/api/cal/*` proxy URL.
+
+The endpoint-by-endpoint contract is **§11**; the staged plan and which endpoints depend on real SEED/appliance hardware vs. pure software is **§12**.
+
+---
+
+## 11. Backend wiring — making every panel real
+
+This section is the authoritative contract for full functionality. It removes the mock layer from the production path (§2.2) by routing every panel through the `homecore-server` BFF gateway (§2.1). Each endpoint is classified by what it depends on:
+
+- **EXISTS** — backend code already in this repo; gateway only proxies/adapts.
+- **NEW-GW** — pure software the gateway itself implements (filesystem, `/proc`, process control, recorder query) — no new external service.
+- **NEW-API** — a small HTTP wrapper to add to an existing in-repo crate (`homecore-api`, `homecore-automation`).
+- **SEED-DEV** — depends on a SEED node's on-device HTTPS API (separate hardware/firmware).
+- **APPLIANCE** — depends on an appliance daemon / accelerator stat source.
+
+### 11.1 Gateway shape
+
+`homecore-server` already mounts `homecore-api` at `/api/*` and the UI at `/homecore`. It gains a new **`/api/homecore/*`** namespace (the dashboard-specific aggregation surface) plus a **`/api/cal/*`** reverse-proxy to the calibration service. The browser issues only same-origin requests; the gateway fans out server-side, holding all upstream credentials (§11.10). Every proxied route has an explicit timeout and maps upstream failure to a typed body (`503 upstream_unavailable`, `504 upstream_timeout`) so one slow tier never stalls the dashboard.
+
+### 11.2 Master endpoint contract (panel → gateway route → upstream → status)
+
+| Panel | UI method (`api.js`) | Gateway route | Upstream / source | Class |

+
+### 11.3 Calibration proxy + RoomState adapter
+
+The calibration service is real but on a different binary/port; the gateway reverse-proxies it under `/api/cal/*` (upstream base from `HOMECORE_CALIBRATION_URL`). Its `RoomState` (`wifi-densepose-calibration/src/runtime.rs`) does **not** match the UI's shape, so the gateway adapts it in `GET /api/homecore/rooms`:
+
+| Real field (`RoomState`) | UI field | Adapter rule |
+|---|---|---|
+| `breathing: Option<SpecialistReading>` | `breathing_bpm: {value,confidence}\|null` | rename; `value`=`reading.value`, `confidence`=`reading.confidence`; `None`→`null` (preserves "not trained") |
+| `heartbeat: Option<…>` | `heart_bpm: {…}\|null` | rename `heartbeat`→`heart_bpm` |
+| `presence/posture/restlessness` | same names `{value,confidence}\|null` | `posture.value`=`reading.label` (class), else numeric |
+| `anomaly: Option<…>` | `anomaly: {value,confidence,threshold}` | inject `threshold`=`MixtureOfSpecialists.veto_threshold` (0.5) |
+| `vetoed` / `stale` | `vetoed` / `stale` | pass through (drives the §4.5/§6 banners) |
+| *(absent)* | `room_id`, `seeds[]` | injected by the gateway from the **room registry** |
+
+A **room registry** (config or derived from `GET /api/cal/v1/calibration/baselines`) maps each `room_id` → bank name + serving SEED ids, so `GET /api/homecore/rooms` returns one adapted record per room. `Option::None` → JSON `null` keeps the null-vs-withheld distinction (§6 invariant 3) intact end-to-end.
+
+### 11.4 SEED registry & device-API proxy
+
+The gateway holds a **SEED registry** (`device_id` → base URL + bearer token + zone), populated by pairing (§4.10) and persisted server-side. `GET /api/homecore/seeds[/:id]` fans out to each SEED's on-device API and shapes the result to the §4.2 card/detail model. Expected SEED-side endpoints (the contract the SEED firmware must satisfy — a subset of its 98 endpoints): health; vector-store stats (`vector_count`, `dim`, `epoch`, `knn_latency_ms`, ingest rate); witness (`len`, `last_verify`, `valid`) + `POST verify`; onboard sensors (BME280/PIR/reed/ADS1115/vibration); reflex rules + thresholds; cognitive analysis (fragility, coherence phases); ingest feeders (ESP32 node ids + packet type `0xC5110003`/`0xC5110002` + rate). Offline/unreachable SEEDs surface as `online:false` (drives the §4.1 red tint) rather than failing the whole list.
+
+### 11.5 Appliance metrics collector (§4.1)
+
+`GET /api/homecore/appliance`, implemented in the gateway: CPU/RAM/uptime from `/proc`; Hailo load + temperature from the Hailo runtime/sysfs (or `ruvector-hailo-worker` stats); service health by probing `ruview-mcp-brain:9876`, `cognitum-rvf-agent:9004`, `ruvector-hailo-worker:50051`; event-bus rate from the `homecore` broadcast channel + its lag counter (already exposed for §4.1/§4.4).
+
+### 11.6 COG supervisor (§4.6)
+
+`GET /api/homecore/cogs`: read each `/var/lib/cognitum/apps/*/manifest.json` ([ADR-100](ADR-100-cog-packaging-specification.md)), the pid file, and verify `binary_sha256` + `binary_signature` (Ed25519) → status/shield. `POST …/cogs/:id/{start,stop,restart}` performs supervised process control; `GET …/cogs/:id/logs` tails `output.log`/`error.log`; `GET/PUT …/cogs/:id/config` reads/writes `config.json`. Hailo-arch COGs join the §11.5 Hailo stats. The Cog Store/App-Registry **browsing** panel was removed per product decision; this is operational management only.
+
+### 11.7 Witness aggregation + privacy (§4.9)
+
+`GET /api/homecore/witness` merges two chains chronologically: the `homecore` Ed25519 state-transition chain (exposed by a small `homecore-api` route over its witness log) and each paired SEED's SHA-256 ingest chain (proxied via the registry), paginated server-side. `GET/POST /api/homecore/privacy` reads/sets per-SEED privacy mode via the SEED privacy control plane ([ADR-141](ADR-141-bfld-privacy-control-plane-modes-attestation.md)) — the POST is the high-stakes confirmed toggle (§4.9). `GET /api/homecore/witness/export` packages both chains into the downloadable attestation bundle.
+
+### 11.8 Event history + automation CRUD (§4.8)
+
+`homecore-api` adds `GET /api/events?since=…` backed by `homecore-recorder` ([ADR-132](ADR-132-homecore-recorder-history-semantic-search.md)) for history (live updates continue over the existing WS). The automation builder persists through `GET/POST/DELETE /api/homecore/automations`, a thin HTTP wrapper over the `homecore-automation` engine's register/list/remove ([ADR-129](ADR-129-homecore-automation-engine.md)). RuView-specific triggers (RoomState thresholds, SEED reflex events) map onto the engine's trigger types.
+
+### 11.9 Entity provenance convention (§4.4/§6)
+
+The first-class provenance badge requires each entity to carry its lineage. Convention: every integration writes `attributes.source` (and, where known, `attributes.seed` / `attributes.cog`) when it sets state; `cog-ha-matter` ([ADR-116](ADR-116-cog-ha-matter-seed.md)) populates these from the ESP32 node → SEED → COG path and HA `via_device`. The gateway/UI resolves node→seed→cog from these attributes (no fabrication; missing lineage renders as "unknown", not invented).
+
+### 11.10 Auth, credentials, config
+
+- **Browser → gateway:** one long-lived access token (the §4.10 LLAT), sent as `Authorization: Bearer`; validated by `homecore-api`'s `LongLivedTokenStore`. The dev default (`allow_any_non_empty`) stays for local runs; production provisions `HOMECORE_TOKENS`.
+- **Gateway → upstreams:** SEED bearer tokens and the calibration token live **only** server-side (SEED registry + `HOMECORE_CALIBRATION_TOKEN`); never sent to the browser. This is the reason the gateway exists.
+- **Config:** `HOMECORE_CALIBRATION_URL`, SEED registry store path, per-proxy timeout (default 2 s), `HOMECORE_UI_DEMO` (dev fixture). No browser CORS needed (same origin); gateway→upstream is server-to-server.
+
+### 11.11 Front-end changes
+
+`api.js`: drop the mock fallback from the production path — methods call the §11.2 gateway routes; `this.base` stays same-origin; the mock layer is reachable only under `?demo=1`/`HOMECORE_UI_DEMO`. Every panel renders a **typed empty/error state** (not mock) when its route returns `503/504`. `mock.js` moves to a dev fixture (kept for the offline test harness, excluded from the production bundle). The §10 frontend tests are re-pointed at the gateway contract (and gain contract tests per §11.2 route).
+
+---
+
+## 12. Delivery plan to full functionality
+
+Staged so each wave is independently shippable behind the gateway, lands real data for a coherent set of panels, and has an explicit acceptance gate. "Class" reuses §11's tags.
+
+| Wave | Scope | Class | Acceptance gate |
+|---|---|---|---|
+| **W1 — Gateway foundation** | `/api/homecore/*` scaffold in `homecore-server`; auth passthrough; per-proxy timeout + typed errors; `api.js` base + remove prod mock (`?demo=1` only); panels get typed empty/error states | NEW-GW | Entities + live WS still green; with no upstreams, every other panel shows "upstream unavailable", **never** mock (unless `?demo=1`); Rust + JS suites pass |
+| **W2 — Rooms + Calibration** | `/api/cal/*` reverse-proxy; `GET /api/homecore/rooms` with the §11.3 RoomState adapter + room registry; wire §4.5 + the §4.7 wizard to real endpoints; delete the in-browser calibration stub | EXISTS (proxy+adapter) | Against a running `calibrate-serve` (replayed CSI), the wizard drives a real baseline→enroll→train→verify and §4.5 shows real `RoomState` with correct stale/veto/null mapping; contract test on the adapter |
+| **W3 — Events + Automations** | `GET /api/events` over `homecore-recorder`; `/api/homecore/automations` over `homecore-automation` | NEW-API | §4.8 history loads from recorder; an automation created in the UI persists and fires via the engine |
+| **W4 — COG management** | `/api/homecore/cogs*` supervisor over `/var/lib/cognitum/apps/` (manifest + pid + sig verify + logs + config) | NEW-GW | §4.6 lists real installed COGs; start/stop/restart works; sha256/signature shield reflects real verification; logs tail |
+| **W5 — SEED tier** | SEED registry + pairing; `/api/homecore/seeds*` device proxy; witness merge + privacy control; ESP32 provisioning | SEED-DEV | Against a real or emulated SEED API, §4.2/§4.3/§4.9/§4.10 show real vector-store/witness/sensor/reflex/cognition data; SEED tokens stay server-side; offline SEED → red tint, not a failed page |
+| **W6 — Appliance + federation + Hailo** | `/api/homecore/appliance` (host metrics + service probes); `/api/homecore/hailo`; `/api/homecore/federation` ([ADR-105](ADR-105-federated-csi-training.md)) | NEW-GW + APPLIANCE | §4.1 health is real; §4.6 Hailo HEF/throughput real; §4.3 federation round/coordinator/Krum real |
+
+**Definition of done (full functionality):** with W1–W6 merged and the upstream tiers running, loading `/homecore` with **no** `?demo=1` flag shows live data on all ten panels, `api.anyDemo()` is false, and no panel renders fabricated values. Panels whose tier is offline show typed empty/error states. The mock layer is reachable only as the `?demo=1` developer fixture.
+
+### 12.1 Wave status (this revision)
+
+| Wave | Status |
+|---|---|
+| **W1 — Gateway foundation** | ✅ DONE — `gateway.rs`, auth passthrough, typed `503/504`, merged into `build_app`; front-end mock removed from prod path + `?demo=1` fixture; typed error states. **Compiled + 12/12 Rust tests + JS suite green + run live.** |
+| **W2 — Rooms + Calibration** | ✅ DONE — `/api/cal/*` reverse-proxy + `GET /api/homecore/rooms` RoomState adapter; front-end calibration stub deleted (now proxies the real API). **Proven live against a calibration upstream** (proxy 200 + adapted shape); null-preservation unit-tested. |
+| **W3 — Events + Automations** | ⏳ gateway returns typed `503` (recorder/automation HTTP wrappers pending); front-end handles it gracefully (history note, builder still usable). |
+| **W4 — COG management** | ✅ supervisor DONE — lists `/var/lib/cognitum/apps/` manifests + pid liveness (returns `[]` live with no apps dir); start/stop/log/config control is the remaining follow-up. |
+| **W5 — SEED tier** | ⏳ gateway returns typed `503` (SEED registry + device proxy pending real/emulated SEED hardware). |
+| **W6 — Appliance + federation + Hailo** | ◑ appliance host metrics from `/proc` + port probes DONE (live `/proc` data verified); Hailo stats + federation remain `503` (need the accelerator stat source / coordinator). |
+
+**Status:** the gateway is **compiled and tested on Rust 1.89** (`cargo test -p homecore-server` = 12/12) and was **run live** (curl proof in §10). The one remaining caveat is intrinsic, not an environment limit: **W3/W5/W6-Hailo/federation depend on services/hardware that are not in this repo** (recorder/automation HTTP wrappers, real SEED nodes, the Hailo stat source), so they return honest typed `503`s and the UI shows error states — exactly as §2.2/§11.2 prescribe. W1/W2/W4/W6-appliance are functional now.
+
+### 12.2 Security review (PR #1082)
+
+A high-effort public-PR review of the merged gateway + front-end surfaced the following, all fixed and pinned by tests (`cargo test -p homecore-server` is now **18/18**):
+
+| # | Severity | Finding | Fix |
+|---|---|---|---|
+| 1 | **HIGH** | **Path-traversal / confused-deputy SSRF** in the `/api/cal/*` reverse-proxy. The wildcard path was interpolated into the upstream URL while `proxy()` attaches the privileged server-side calibration bearer, so `/api/cal/v1/../../x` (or `..%2f`, `%2e%2e`, leading `/`, `\`, double-encoded `%252e`) could escape the `…/api/` scope **with the token**. | `validate_proxy_path()` decode-then-checks and rejects absolute / backslash / dot-segment / encoded-traversal paths with a typed **400 before the URL is built** (GET **and** POST); legit `v1/...` paths still pass. |
+| 2 | Correctness | **CORS + tracing didn't cover gateway routes** — `/api/homecore/*` + `/api/cal/*` were `.merge()`d outside `homecore-api::router()`'s layers. | The audited HC-05 `build_cors_layer()` + `TraceLayer` are now applied to the whole merged app in `main.rs`. |
+| 3 | Honesty (§6) | **Fabricated data** — hardcoded `anomaly.threshold: 0.5` in the adapter; dashboard rendered `"null%"`/`"null°C"`; COG Hailo pill hardcoded `"connected"`; `rooms.js` defaulted a null threshold to `0.8`. | Threshold passes through the real upstream value or emits `null` (withheld); dashboard renders `—`; the Hailo pill reflects the real appliance probe; the UI treats a null threshold as withheld. |
+| 4 | Robustness | A string `hef` (forwarded verbatim) threw on `.forEach`/`.join`; `frames/target` could be `NaN%`/`Infinity%`; calibration Restart leaked the baseline `setTimeout` poll. | `asArray()` coercion; `target > 0` guard; cancellable poll cleared on Restart / panel teardown. |
+| 5 | Perf | Sequential per-bank RoomState fetches; blocking `std::net::TcpStream::connect_timeout` probes on an async handler; `mock.js` statically bundled. | Concurrent `futures::join_all`; async `tokio::net::TcpStream` + `timeout`; demo-only dynamic `import()` of `mock.js`. |
+
+**Known limitations carried forward (not regressions):**
+- **`reqwest` rustls-only is a workspace-wide concern.** `homecore-server` opts into `rustls-tls` only, but cargo feature-unification means any sibling crate enabling the default `native-tls` re-introduces OpenSSL into the final binary. A true "no OpenSSL on the appliance" guarantee requires aligning **every** reqwest-pulling crate on rustls-only — out of scope for this PR; documented at the dependency in `Cargo.toml`.
+- **DEV-mode auth.** When `HOMECORE_TOKENS` is unset, the token store falls back to `allow_any_non_empty()` (any non-empty bearer accepted) on `0.0.0.0`. This is pre-existing and intentionally **unchanged** here; the loud boot `warn!` is retained. Provision real tokens (`HOMECORE_TOKENS=…`) before exposing the server to a network.

+
+---
+
+## 1. Context
+
+ADR-126 (the HOMECORE master) decided to reimplement Home Assistant (HA) natively in Rust.
+HA persists every state change to a SQLite *recorder* database; downstream features
+(history graphs, the logbook, long-term statistics, automation conditions that reference
+past state) all read that store. HOMECORE therefore needs a durable state-history backbone.
+
+Two forces shape the decision:
+
+1. **Migration / coexistence.** Users adopting HOMECORE will have an existing HA
+   `recorder` database. Reusing HA's on-disk schema (rather than inventing a new one) lets
+   HOMECORE read an existing HA `home-assistant_v2.db` directly and lets HA-aware tooling
+   read HOMECORE's store. This is the same trust boundary that `homecore-migrate`
+   (ADR-165) handles for `.storage/*.json`.
+2. **Semantic queries.** HA history is queried with SQL `BETWEEN`/`WHERE` clauses. The
+   HOMECORE platform already carries ruvector (ADR-124) for vector search, so the recorder
+   can additionally embed state changes and answer natural-language queries
+   ("which kitchen devices were warm at 3 PM?") via k-NN — a capability HA does not have.
+
+The recorder is the **durable-state surface**: if it is wrong, history, logbook, and
+historical-condition automations are all wrong. ADR-164 flagged it as a CRITICAL coverage
+gap precisely because such a load-bearing crate had no governing ADR.
+
+## 2. Decision
+
+Ship `homecore-recorder` as a SQLite state-history recorder with an HA-compatible schema
+and an optional ruvector-backed semantic index, in three phases. P1 and P2 are built and
+tested; P3 is planned.
+
+### 2.1 Storage — SQLite with the HA recorder schema (P1, shipped)
+
+- Persist via `sqlx` with the SQLite backend only (no Postgres, no TLS feature set).
+- Mirror HA recorder **schema v48** so the store is bidirectionally readable
+  (`src/schema.rs`):
+  - `state_attributes` — shared attribute JSON blobs, deduped by an FNV-1a 64-bit hash
+    stored as a signed `i64` (matches HA's dedup key);
+  - `states` — one row per state write (`entity_id`, `state`, `attributes_id` FK,
+    `last_changed_ts`/`last_updated_ts` as REAL Unix seconds, `context_id` UUID);
+  - `events` — domain events (`event_type`, `event_data` JSON, `time_fired_ts`);
+  - `recorder_runs` — boot/shutdown bookends for history-gap detection.
+- All DDL uses `CREATE TABLE IF NOT EXISTS`, so schema application is idempotent and safe
+  on every startup.
+- Default persistence path `.homecore/home.db` (configurable).
+
+### 2.2 Capture — listener on the HOMECORE event bus (P1, shipped)
+
+- `RecorderListener` subscribes to the HOMECORE event bus (ADR-127) and captures
+  `StateChanged` events, writing snapshots through `Recorder` (`src/listener.rs`,
+  `src/db.rs`).
+- A `DedupEngine` (`src/dedup.rs`) skips redundant writes when the state hash is unchanged,
+  matching HA's stateful-listener behaviour.
+
+### 2.3 Semantic search — ruvector HNSW (P2, shipped, feature-gated)
+
+- Behind the `ruvector` Cargo feature, the `Recorder` additionally calls a `SemanticIndex`
+  implementation (`src/semantic.rs`) that embeds state attributes and stores vectors in a
+  `ruvector-core` HNSW index for k-NN search.
+- P2 embeddings are **hash-based** (sha2) — a deliberate, honest placeholder. They give a
+  working HNSW surface without claiming sentence-level semantic quality.
+- When the feature is off, `NullSemanticIndex` satisfies the `SemanticIndex` trait bound
+  with no allocation, so the structural recorder ships independently of ruvector.
+
+### 2.4 Real sentence embeddings (P3, planned — not yet built)
+
+- Replace the hash embeddings with ruvector-attention sentence embeddings (dim → 384). Not
+  implemented; tracked as a follow-up. The README and `Cargo.toml` label this P3 explicitly.
+
+### 2.5 Test evidence (as shipped)
+
+- P1: 14 tests (`cargo test -p homecore-recorder --no-default-features`).
+- P2: 20 tests (`cargo test -p homecore-recorder --features ruvector`).
+
+## 3. Consequences
+
+**Positive.**
+
+- HA-schema compatibility makes migration (ADR-165) and coexistence cheap: HOMECORE can
+  read an existing HA `recorder.db`, and any SQLite tool can read HOMECORE's history.
+- The semantic index is **additive** and feature-gated: the durable structural recorder has
+  no hard dependency on ruvector, so the storage backbone ships first.
+- Standard SQLite means no proprietary export format; history is directly queryable.
+
+**Negative / honest limits.**
+
+- P2 semantic search uses **hash embeddings**, not real sentence embeddings — query quality
+  is limited until P3. This is disclosed in the crate docs and here; it must not be cited as
+  semantic-quality-validated.
+- No per-crate benchmarks exist yet; the latency figures in the README
+  (state-write p50 < 2 ms, semantic search < 10 ms on 1 M records) are design targets /
+  estimates, **needs verification** with a criterion baseline.
+- Pinning to HA schema v48 couples HOMECORE to a specific HA recorder schema generation;
+  future HA schema bumps require an explicit migration step.
+
+**Neutral.**
+
+- This ADR governs the recorder crate only. The query/REST surface over recorder data is
+  HOMECORE-API (ADR-130, P3); automation conditions on historical state are
+  HOMECORE-automation (ADR-129, P3).
+
+## 3a. Security review (2026-06, post-ADR-154–159 sweep)
+
+A beyond-SOTA security review of `homecore-recorder` covered SQL injection, retention/purge
+correctness, fail-closed write integrity, semantic-store NaN poisoning, and PII exposure.
+
+**Confirmed clean (with evidence):**
+
+- **SQL injection — clean.** Every query in `db.rs` uses bound `?` parameters; no user- or
+  entity-influenceable value is interpolated into SQL via `format!`/concatenation. The only
+  `format!` builds the `LIKE` *pattern* string, which is itself **bound** as a parameter with
+  `ESCAPE '\\'` and `% _ \` escaping — so a metacharacter payload is matched literally. Pinned
+  by `malicious_entity_id_is_stored_literally_not_executed` (a `'; DROP TABLE states; --` state
+  value leaves the table intact and round-trips verbatim) and
+  `like_metacharacters_in_query_are_literal_not_wildcards`.
+- **NaN-index poisoning — structurally impossible.** Embeddings are SHA-256 → `i32` →
+  `f32`; an `i32`→`f32` cast is always finite (never NaN/Inf), and an all-zero-digest is
+  guarded by the `norm > 1e-10` check. Empty-index search, empty-string query, and `k=0` were
+  probed and all return `Ok(0)` with no panic. (Unlike the calibration/vitals/geo paths, no raw
+  sensor float ever reaches the index.)
+- **Fail-closed writes.** A removal event returns `Ok(None)`; semantic-index failure is logged,
+  not propagated, so it never blocks the durable SQLite write; `EntityId` parse failure falls
+  back to a sentinel rather than panicking.
+
+**Fixed (real bounding bugs):**
+
+- **Memory-DoS — `get_state_history` was unbounded.** No `LIMIT`, so a wide time window over a
+  high-frequency entity loaded an unbounded row set into memory. Now capped at
+  `MAX_HISTORY_ROWS` (1,000,000); sibling search paths were already `k`-bounded.
+- **Disk-DoS / documented-but-missing `purge`.** The README advertised `Recorder::purge`, but
+  no retention path existed → unbounded disk growth. Added a **transactional** `purge(older_than)`
+  with an **exclusive** cutoff (idempotent, no off-by-one) that deletes old `states`/`events` and
+  GCs orphaned `state_attributes` blobs (dedup-shared blobs kept until their last referrer is gone).
+
+`homecore-recorder` tests: 19 → 25 (`--no-default-features`) / 25 → 31 (`--features ruvector`),
+0 failed. Python deterministic proof unchanged (recorder is off the signal proof path).

+## 6. Security review (beyond-SOTA, untrusted-input → action path)
+
+A focused security review of the Assist pipeline — `utterance → recognizer →
+intent → handler → action`, plus `RufloRunner` — treating the utterance as
+untrusted input (voice transcripts, the WebSocket `assist` command). This
+surface was not covered by the ADR-154–159 sweep.
+
+### 6.1 Finding fixed — HC-ASSIST-01 (unbounded-utterance DoS, LOW)
+
+Both `RegexIntentRecognizer::recognize` and the semantic `recognize_scored`
+accepted utterances of **unbounded length** and ran `to_lowercase()` (a full
+clone) + a per-registered-pattern scan (and, in the semantic path, full
+tokenisation + feature-hash embedding) before any bound — an allocation/CPU
+amplification on attacker-controlled input. The `regex` crate is **linear-time**
+(RE2-style finite automaton, no catastrophic backtracking), so this was a
+throughput/memory DoS, not a hang.
+
+**Fix:** `MAX_UTTERANCE_BYTES = 4096` (far above any real spoken command),
+checked at **both** recognizer boundaries *before* any allocation/scan. An
+over-length utterance **fails closed** to `Ok(None)` — no intent, no action,
+identical to an unrecognised phrase — so it can never be coerced into firing a
+handler. Pinned by `over_length_utterance_fails_closed` (an over-length
+utterance that *contains* a valid command resolves to `None`, which would have
+matched on the old code) and `over_length_utterance_fails_closed_semantic`.
+
+### 6.2 Dimensions confirmed clean (with evidence)
+
+- **Command / argument injection — NO SUBPROCESS SURFACE.** The `RufloRunner`
+  has exactly two impls: `NoopRunner` (no process) and `LocalRunner` (runs the
+  local recognizer, no process). There is **no** `std::process` / `tokio::process`
+  / `Command` / process `.spawn()` anywhere in the crate — the trait `spawn` is
+  only a `started: bool` lifecycle flag — and `RufloRunnerOpts.{script_path,env}`
+  are **inert data, never consumed**. The live `node ruflo-agent.js` runner is
+  genuinely data-gated/future (P2). Defence-in-depth: the `entity_id` capture
+  class `[a-z_][a-z0-9_ .]*` **excludes every shell/SQL metacharacter**, so even
+  when an injection-shaped utterance resolves (the regex is not exact-anchored),
+  the captured slot is a clean token — sanitisation by construction. Pins:
+  `shell_metachars_never_survive_into_a_resolved_slot`,
+  `runner_opts_are_inert_no_process_spawned`,
+  `pipeline_injection_shaped_utterance_carries_no_metachars_to_service`.
+- **ReDoS — STRUCTURALLY IMPOSSIBLE.** `regex 1.12.3` (no `fancy-regex` in the
+  dependency tree) is linear-time; a classic `(a+)+$` shape on adversarial input
+  completes in bounded time. Pin:
+  `pathological_backtracking_pattern_completes_in_bounded_time`. Patterns are
+  operator-registered, not user-supplied, in any case.
+- **NaN-poisoning — EMBEDDINGS STRUCTURALLY FINITE.** The embedding path takes
+  only `&str` and produces values via FNV feature-hashing + a guarded L2
+  normalise (`norm > 1e-12`); no external float input, no unguarded division, so
+  a crafted utterance cannot inject NaN/Inf to poison the cosine k-NN. Cosine
+  against the zero vector is a finite `0.0`; an empty index `max_by` returns
+  `None` (no panic); the NaN-safe `partial_cmp().unwrap_or(Equal)` is already in
+  place. Pins: `embeddings_are_structurally_finite`,
+  `cosine_with_zero_vector_is_finite_not_nan`,
+  `empty_utterance_against_empty_index_no_panic_no_match`.
+- **Intent confusion / fail-closed.** An unrecognised utterance → `not_understood()`
+  (no service call); a recognised intent with no registered handler →
+  `not_understood()`; semantic below-threshold / empty-index → regex fallback.
+  No default high-privilege intent, no fail-open path.
+- **Panic-on-input.** No `unwrap`/`expect`/index reachable from a crafted
+  utterance; the one `exemplars[id]` index uses an `id` from `enumerate()` over
+  the append-only exemplar `Vec` (no remove API), so it is always in bounds.
+
+`cargo test -p homecore-assist --no-default-features`: **29→36, 0 failed** (+7);
+default/`semantic`: **39→48, 0 failed** (+9). Python deterministic proof
+unchanged (homecore-assist is off the signal proof path).

+
+## Witness Integrity Review (2026-06-14) — domain-separation fix
+
+A beyond-SOTA security review of `wifi-densepose-engine` (the composition root
+that builds the §2.7 trust witness in `witness_of`) found a real **witness
+domain-separation gap**, now fixed.
+
+**Finding (witness-gap, HIGH).** `witness_of` concatenated `model_version`,
+`calibration_version`, and `privacy_decision` boundary-to-boundary, and the
+variable-length `evidence` list carried no explicit count. A string straddling a
+field boundary therefore collided with a *different* trust decision —
+e.g. a per-room adapter id (ADR-150 §3.4, operator-influenceable) that absorbs
+the leading bytes of the calibration epoch (`model="…cal:00a"`, `cal="b"`)
+produces the **same** witness as `model="…"`, `cal="cal:00ab"`. Two distinct
+privacy-relevant input tuples → one witness defeats the "any privacy-relevant
+delta → different witness" guarantee this ADR's §2.7 witness exists to provide.
+
+**Fix.** The witness now (a) prepends a domain tag `ruview.engine.witness.v1`,
+(b) writes an explicit 8-byte evidence count, and (c) **length-prefixes every
+field** (8-byte LE length ‖ bytes), so field framing is unambiguous regardless
+of contents. This is a witness-layout change (all prior witness bytes are
+invalidated by design); downstream consumers only assert witness *relationships*
+(`assert_ne`/`assert_eq` across runs), not absolute bytes, so nothing breaks.
+
+Pinned by `witness_distinguishes_model_calibration_boundary` and
