feat(firmware): gate LED gamma viz behind CONFIG_LED_GAMMA_VIZ (ADR-183 follow-up) (#1129)

The 40 Hz gamma flicker is now Kconfig-gated (default y, unchanged
behaviour). Set CONFIG_LED_GAMMA_VIZ=n for a dark, lower-power boot (the
LED is simply cleared) — important for photosensitive deployments, no
source edit needed. The colormap saturation point is now operator-tunable
via CONFIG_LED_MOTION_FULLSCALE_MILLI (default 250 = 0.25).

Build + flash confirmed on ESP32-S3 N16R8 (COM8): default y still arms the
gamma timer, CSI flows. ADR-183 updated (gate moved from follow-up to done).

+### Fixed
+- **Multistatic fusion guard interval is now operator-configurable — fixes permanent trust demotion with WiFi-synced ESP32 nodes (#1049).** Two independently-clocked ESP32-S3 boards on ESP-NOW sync drift 10–150 ms (typ. ~70 ms) — the 100 ms beacon + WiFi-MAC jitter cannot hold them within the published 60 ms default guard, so the governed-trust cycle permanently demoted to `Restricted`, suppressed all pose output, and spun the error counter to 200k+ with **no escape hatch but a container restart**. Added a **direct `WDP_GUARD_INTERVAL_US` override** (+ optional `WDP_SOFT_GUARD_US`) to `multistatic_guard_config_from_env`, so a deployment can lift the hard guard past its measured spread (e.g. `WDP_GUARD_INTERVAL_US=200000`) without having to know its exact TDM schedule. Precedence is most-specific-wins: a direct override beats the existing `WDP_TDM_SLOTS`+`WDP_TDM_SLOT_US` schedule-derived guard, which beats the 60 ms/20 ms default; the override is applied on top of whichever base is selected, the soft band is always clamped strictly below the hard guard, and a malformed/zero value is ignored (falls back to the base rather than breaking fusion). The effective guard is now logged at startup. Pinned by 6 new tests (`multistatic_guard_config_tests`): direct-override-wins / beats-TDM-derived / soft-clamped-below-hard / lowering-hard-pulls-soft-down / malformed-or-zero-falls-back / default-when-unset. `wifi-densepose-sensing-server` bin tests **449 → 455**, 0 failed; Python proof VERDICT PASS, hash unchanged (off the signal proof path).

 ### Security
 - **`wifi-densepose-occworld-candle` — beyond-SOTA security + correctness review (Milestone #9, crate 4/4).** (1) **HIGH (MEASURED) — checkpoint-load crash on any int32 tensor** (`model.rs::safetensor_dtype_to_candle`). `safetensors::Dtype::I32` was mapped to `candle_core::DType::I64` and the raw int32 byte buffer (4 bytes/elem) was then handed to `Tensor::from_raw_buffer(.., I64, shape, ..)`. Candle derives `elem_count = data.len() / dtype.size_in_bytes()`, so the I64 path halved the element count while keeping the *original* shape — yielding a tensor whose declared shape claims twice as many elements as its backing storage holds. Reading it **panics** (`range end index 6 out of range for slice of length 3` — slice OOB inside candle-core) on any attacker-supplied or PyTorch-exported checkpoint containing an int32 tensor (common: index/buffer tensors). Fixed by mapping `I32 → DType::I32` (and `I16 → DType::I16`), both first-class candle dtypes. Reproduction recorded on old code; pinned by `tests/checkpoint_loading.rs::int32_tensor_loads_with_consistent_shape_and_values` (panics on old, passes on new) plus F32/I64/corrupt-file control cases. (2) **LOW (MEASURED) — `predict()` lacked frame/batch validation at the input boundary** (`inference.rs`). It validated H/W/D but not the externally-supplied frame count; an `f_in > num_frames*2` over-indexed the temporal positional embedding deep in the transformer and surfaced as a cryptic candle "gather" `InvalidIndex` (returned error, not a panic — candle bounds-checks), and a zero frame/batch dim fed a zero-element tensor into the pipeline. Now rejected at the boundary with a clear `ShapeMismatch`. Pinned by `predict_rejects_zero_frames` / `predict_rejects_too_many_frames` / `predict_accepts_frame_count_at_capacity`. (3) **LOW (MEASURED) — divide-by-zero panic on a degenerate input to the public `VQCodebook::encode`** (`vqvae.rs`): a rank-0 / empty-last-dim tensor made `last == 0` and panicked on `elem_count() / last`. Now fails closed with a clear error. Pinned by `encode_rejects_scalar_without_panicking`. **Dimensions confirmed CLEAN with evidence:** panic surface — zero `unwrap()`/`expect()`/`panic!`/`unreachable!` in production code paths (grep evidence; all error handling via `?`/`map_err`); NaN-state-poisoning — N/A (engine is stateless between `predict` calls, input is `u8` class indices so non-finite input is structurally impossible, no persistent world-model buffer to latch into); unbounded-alloc / shape-data mismatch from malformed weights — defended upstream by `safetensors::validate()` (overflow-checked `nelements*dtype.size()` vs declared byte range, rejected before reaching candle); secrets — none (grep clean, only `token_h`/`token_w` config fields match). `unsafe_code = forbid` in the crate manifest. **Build/validation status (MEASURED on Windows):** crate builds and tests under `cargo test -p wifi-densepose-occworld-candle --no-default-features` — **29/29 pass** (20 unit + 4 checkpoint_loading + 3 predict_honesty + 2 doc) after fixes; `cargo test --workspace --no-default-features` = 0 failed across all crates (lone `wifi-densepose-desktop` `api_integration` failure was a Windows "Access is denied (os error 5)" file-lock flake — re-ran in isolation **21/21 pass**); Python proof VERDICT PASS, hash `f8e76f21…446f7a` unchanged. *Warrants ADR slot 179 (parent to author).*
 - **`wifi-densepose-wasm-edge` beyond-SOTA closing review — boundary NaN-state-poisoning guard + clean-with-evidence attestation (ADR-040 edge crate, ~70 modules).** Closing pass of the security campaign over the last untouched sizeable crate. **One real finding fixed (LOW / source-analysis + reproduced):** the two WASM↔host frame boundaries (`lib.rs::on_frame`/`on_timer` and `bin/ghost_hunter.rs::on_frame`) read raw IEEE-754 `f32` from the `csi_get_phase`/`csi_get_amplitude`/`csi_get_variance`/`csi_get_motion_energy` host imports **without any finiteness check** — the entire crate had **zero** `is_finite`/`is_nan` guards, and the in-crate `clamp` helpers propagate NaN (`NaN < lo` and `NaN > hi` are both false). A single non-finite value (firmware DSP bug, uninitialised buffer, or hostile host) latches NaN into the long-lived per-module accumulators (EMA, Welford, phasor sums, anomaly baselines); once latched, every downstream comparison evaluates `false`, so detectors fail **degraded** (stuck gate state, silently-disabled anomaly checks) — silent corruption, not a crash (WASM `panic=abort` is *not* tripped: no indexing/`unwrap` on the poisoned value). Threat model is a **semi-trusted** boundary (the Tier-2 DSP firmware supplies the imports, not direct network/JS), hence LOW severity / defense-in-depth. **Fix:** added `sanitize_host_f32()` (maps non-finite→`0.0`, `core`-only so it holds in `no_std`) applied at every `host_get_*` float read — a single chokepoint covering all ~70 downstream modules, mirroring the existing M-01 negative-`n_subcarriers` boundary clamp. **Pinned by** `boundary_tests::{sanitize_passes_finite_values_through, sanitize_maps_non_finite_to_zero, coherence_monitor_nan_latches_without_sanitize_but_not_with}` — the last asserts on the *current* `CoherenceMonitor` that a raw NaN frame latches the smoothed score (documents the hazard) while the boundary-sanitized path stays finite. **Dimensions attested CLEAN with evidence (source-analysis):** (a) **panic-on-input** — every non-test `unwrap()`/`expect()` is either `#[cfg(test)]` or in the `std`-gated RVF *builder* host tool writing to an in-memory `Vec` (infallible); no `panic!`/`unreachable!`/`todo!`/`get_unchecked` in any hot path. (b) **shape/bounds** — all frame-buffer access is `min()`-clamped (`MAX_SC=32`, `DTW_MAX_LEN`, `LCS_WINDOW`, `PATTERN_LEN`), all index-by-cast sites (`feature_id as usize`, `conclusion_id`, `minute_counter`, `plan_step`) are either compile-time-const-bounded or `if idx <`/`%`-guarded; negative `n_subcarriers` already mapped to 0 (M-01). (c) **memory/leak** — no `move ||` closures, no `mem::forget`/`Box::leak`/`.leak()`; the only `Box::new` is in the `std`-gated `skill_registry` (one-time init, bounded). (d) **secrets** — none (grep clean). **MEASURED build/test evidence:** host `cargo test --features std,medical-experimental` = **672 passed / 0 failed** (was 669 pre-fix; +3 new tests); the real deployment artifacts all build clean on the actual target — `cargo build --target wasm32-unknown-unknown --release` (no_std/panic=abort default lib), `--bin ghost_hunter --no-default-features --features standalone-bin`, and `--features medical-experimental` (toolchain 1.89 per `rust-toolchain.toml`). No ADR slot needed — a single LOW defense-in-depth boundary fix; CHANGELOG attestation suffices.

+
+## Context
+
+RuView (WiFi-DensePose) is a deep stack — 15 Rust crates, an ESP32 firmware line,
+a sensing-server, a CLI, ~180 ADRs, a calibration pipeline, training recipes, and a
+hard cultural rule that **every claim must be independently reproducible** (the
+"prove everything" ethos, after the project was accused of AI-slop). The barrier to
+entry is correspondingly steep: a newcomer who wants to "set up WiFi sensing" must
+discover the right firmware variant, provision an ESP32 over a Windows-only Python
+subprocess, point it at the sensing-server, run `calibrate` → `enroll` →
+`train-room`, and know which numbers are MEASURED vs CLAIMED. We already encode this
+knowledge as **Claude Code subagents** (`ruview-onboarding-guide`,
+`ruview-config-engineer`, `ruview-training-engineer`) — but those only exist inside
+*this* repo's `.claude/agents/`, only on Claude Code, and only for someone who has
+already cloned the monorepo.
+
+Separately, this session shipped **MetaHarness** (`metaharness@0.1.15`): a tool that
+*"mints a custom AI agent harness from any repo"*, runnable on **9 hosts**
+(claude-code, codex, pi-dev, hermes, openclaw, rvm, copilot, opencode,
+github-actions) over a wasm-primary / NAPI-RS-fallback **kernel**, with a
+**cost-optimal model router** (`@metaharness/router`, the productized DRACO Phase-2
+k-NN finding) and ed25519/SLSA/SBOM provenance baked in. Crucially, MetaHarness
+**already ships a `vertical:ruview` template** in its template list. That template
+is generic scaffolding; it is not wired to RuView's actual tools, agents, or the
+"prove everything" guardrails.
+
+The gap: **there is no single, host-portable, provenance-signed entry point that
+gives any user an AI agent that actually knows how to operate RuView.** A user
+should be able to run one command —
+
+```bash
+npx ruview
+```
+
+— in an empty directory (or alongside an ESP32) and get an agent harness that can
+onboard them, configure firmware, drive a live capture, train a room model, and
+**refuse to overstate accuracy** — on whichever coding host they already use.
+
+## Decision
+
+**Mint a first-class RuView agent harness from this repo using MetaHarness, harden
+its `vertical:ruview` template into a RuView-specific harness with a real MCP tool
+surface and the project's honesty guardrails, and publish it as `npx ruview`.**
+
+`npx ruview` is *not* a new runtime. It is a **thin, versioned distribution** of a
+MetaHarness harness: the kernel + host adapters + a RuView "genome" (skills, agents,
+MCP tools, guardrails) generated from and pinned against this monorepo. The harness
+is the product; `npx ruview` is the front door.
+
+### Why mint-from-repo instead of hand-writing a harness
+
+MetaHarness's value here is exactly the work we would otherwise hand-roll across 9
+hosts: host-specific config (`.claude/settings.json` MCP + hooks for claude-code,
+the codex/copilot/opencode equivalents), the kernel that abstracts wasm-vs-native,
+the cost router, and the provenance chain. We write the **RuView knowledge once** as
+host-neutral genome assets; MetaHarness projects them onto each host adapter. This
+also keeps the harness regenerable: when the CLI or an ADR changes, re-mint and
+re-pin rather than maintaining 9 divergent copies.
+
+### What the harness contains (the RuView genome)
+
+1. **Skills / playbooks** (host-neutral markdown, projected to each host's skill
+   format):
+   - `onboard` — zero-to-sensing path picker (Docker demo / repo build / live
+     ESP32), the physics caveats, the hardware table. Port of
+     `ruview-onboarding-guide`.
+   - `provision-node` — ESP-IDF v5.4 Windows-subprocess build/flash/provision flow
+     (the exact MSYSTEM-stripped invocation from `CLAUDE.local.md`), firmware
+     variant selection (8MB display / 4MB no-display / C6), NVS + WiFi + channel /
+     MAC-filter overrides (ADR-060).
+   - `calibrate-room` — `baseline → enroll → extract → train` via the
+     `wifi-densepose` CLI (`calibrate`/`calibrate-serve`/`enroll`/`train-room`/
+     `room-watch`, ADR-151).
+   - `train-pose` — camera-supervised + camera-free training, the MEASURED-vs-CLAIMED
+     discipline, the mean-pose baseline check (ADR-079, ADR-152, ADR-181).
+   - `verify` — run the witness bundle + Python proof (`verify.py` → VERDICT: PASS),
+     ADR-028.
+   - Ports of `ruview-config-engineer` and `ruview-training-engineer`.
+
+2. **MCP tool surface** (`@metaharness/kernel`-hosted MCP server, one schema per
+   capability — see "MCP tools" below). This is what makes the harness *operate*
+   RuView, not just talk about it.
+
+3. **Guardrails** (the differentiator): the harness's system prompt and a
+   pre-output hook enforce the "prove everything" rule — accuracy numbers must be
+   tagged MEASURED (with a reproducer) or CLAIMED; the agent must run the mean-pose
+   baseline before quoting PCK; firmware fixes are never presented as
+   hardware-validated without a real boot log (the exact discipline this session
+   followed for `v0.8.1-esp32`).
+
+4. **Host adapters** — claude-code first (P1), then codex / opencode / copilot /
+   pi-dev / hermes / rvm / github-actions (P3+), each via the published
+   `@metaharness/host-*` package.
+
+5. **Router** — `@metaharness/router` routes each step to the cheapest adequate
+   model (e.g. a var-rename or a log-grep → Haiku; calibration-math reasoning or a
+   security review → Sonnet/Opus), mirroring the repo's 3-tier routing (ADR-026).
+
+### MCP tools (the operational surface)
+
+| Tool | Wraps | Purpose |
+|------|-------|---------|
+| `ruview.onboard` | docs + agent | Pick a setup path, print the next concrete command |
+| `ruview.node.flash` | ESP-IDF subprocess (ADR `CLAUDE.local.md`) | Build + flash a firmware variant to a COM port |
+| `ruview.node.provision` | `provision.py` | Set SSID/password/target-ip/channel/MAC-filter over serial |
+| `ruview.node.monitor` | pyserial | Stream boot log; assert CSI is flowing (MGMT+DATA) |
+| `ruview.server.up` | sensing-server | Start the Axum sensing-server (`:3000`/`:5005`/`:8765`) |
+| `ruview.calibrate` | `wifi-densepose calibrate`/`enroll`/`train-room` | Run the ADR-151 room pipeline |
+| `ruview.room.watch` | `wifi-densepose room-watch` | Live presence/vitals from a trained room |
+| `ruview.verify` | `scripts/generate-witness-bundle.sh` + `verify.py` | Produce/verify the witness bundle (must be N/N PASS) |
+| `ruview.claim.check` | static lint | Scan output for untagged accuracy claims; flag MEASURED-vs-CLAIMED |
+
+Each tool returns structured JSON and is fail-closed: a tool that cannot prove its
+result (e.g. `ruview.node.monitor` sees no CSI callbacks) returns an honest negative,
+never a fabricated success — consistent with the RuField `map_privacy` fail-closed
+posture (ADR-262 §3.3).
+
+### The mint + pin flow (how the harness is produced)
+
+```bash
+# P1 — mint from this repo, claude-code host, RuView vertical
+npx metaharness ruview --template vertical:ruview --host claude-code \
+  --from-existing . --description "RuView WiFi-sensing operator agent" \
+  --target ./harness/ruview
+
+# readiness + fit/cost/safety scorecards (ADR-041) — gate before publish
+npx metaharness genome .        # 7-section repo readiness
+npx metaharness score .  --json # fit / cost / safety
+npx metaharness analyze .       # recommended harness plan (no-exec)
+```
+
+The minted harness is committed under `harness/ruview/` and **pinned** (kernel +
+host-adapter + router versions locked) so `npx ruview` is reproducible. Re-minting on
+a CLI/ADR change is a reviewed PR, not an implicit regeneration.
+
+### Distribution: `npx ruview`
+
+A small published package whose `bin` boots the pinned harness via the kernel:
+
+- **Preferred name:** `ruview` (currently **free** on npm — verified 2026-06-17).
+- **Risk:** npm's typosquat filter may reject `ruview` as too close to `review` /
+  `preview` (this session hit exactly that on `ruvn`→`levn`/`raven` and
+  `worldgraph`→`world-graph`). **Fallback:** publish scoped `@ruvnet/ruview` (also
+  free) and/or `npx ruvnet/ruview` straight from GitHub. Decide at publish time;
+  do not unpublish to rename (the 24-h name-lock lesson from `worldgraphs`).
+- `bin: { "ruview": "bin/cli.js" }` — note **`bin/cli.js`, not `./bin/cli.js`** (npm
+  strips the `./` form; this broke `ruvn@0.1.0` this session).
+- `npx ruview` with no args → `onboard` skill (interactive path picker).
+  `npx ruview <skill> [...]` → run a specific skill. `npx ruview --host codex` →
+  install the harness into an existing repo for that host.

+Provenance: the harness ships an **ed25519 witness + SBOM (SPDX) + SLSA** chain
+(MetaHarness already does this for minted harnesses), so a recipient can verify the
+RuView harness was built from a specific monorepo commit — the agentic analogue of
+the firmware witness bundle (ADR-028).
+
+## Phases
+
+- **P1 — Mint & pin (claude-code).** `npx metaharness ruview --template
+  vertical:ruview --from-existing . --host claude-code`. Port the three `ruview-*`
+  subagents into host-neutral genome skills. Commit under `harness/ruview/`, pin
+  versions. Acceptance: `npx metaharness score .` ≥ threshold; the harness can run
+  `onboard` and `verify` end-to-end locally.
+- **P2 — MCP tool surface.** Implement the `ruview.*` MCP tools over the kernel
+  (start with `onboard`, `verify`, `claim.check`, `node.monitor` — the read-only /
+  proving tools), then the mutating ones (`node.flash`, `provision`, `calibrate`).
+  Acceptance: `ruview.verify` returns the witness bundle PASS as structured JSON;
+  `ruview.claim.check` flags a seeded untagged "100% accuracy" string.
+- **P3 — Publish `npx ruview` + multi-host.** Publish the bin package (name decision
+  per Distribution). Add codex / opencode / copilot / pi-dev / hermes / rvm /
+  github-actions adapters. Acceptance: `npx ruview` cold-starts on ≥3 hosts and runs
+  `onboard`; provenance verifies.
+- **P4 — Router + guardrail hardening.** Wire `@metaharness/router`; calibrate the
+  3-tier routing on a RuView task set. Make the MEASURED-vs-CLAIMED guardrail a hard
+  pre-output gate. Acceptance: a benchmark of RuView tasks shows cost reduction vs
+  all-Opus with no quality regression; the guardrail blocks an untagged accuracy
+  claim in a red-team prompt.
+
+## Consequences
+
+**Positive**
+- One reproducible, signed entry point (`npx ruview`) that operates RuView on the
+  host the user already has — onboarding goes from "clone a 15-crate monorepo" to a
+  single `npx`.
+- The "prove everything" ethos becomes **executable**, not just documentation: the
+  harness *enforces* MEASURED-vs-CLAIMED and the mean-pose baseline.
+- Knowledge written once (host-neutral genome) instead of 9× per host; regenerable
+  from the repo as the system evolves.
+- Dogfoods MetaHarness on a hard real vertical, surfacing bugs back to
+  `agent-harness-generator` (this session already filed #9–#13 there).
+
+**Negative / risks**
+- **Drift:** a pinned harness goes stale as the CLI/ADRs move; mitigated by a
+  re-mint-on-change PR ritual and a CI check that the genome's referenced
+  CLI flags still exist.
+- **Surface area:** mutating MCP tools (`node.flash`, `provision`) touch hardware and
+  the network — must be permission-gated and fail-closed; the firmware-flash tool
+  must never claim hardware validation without a captured boot log.
+- **Name/typosquat:** `ruview` may be rejected at publish; scoped fallback decided in
+  P3. Do not unpublish-to-rename.
+- **Host parity:** not all 9 hosts support MCP + hooks equally; the guardrail gate
+  may degrade to advisory on weaker hosts — must be disclosed in the badge, not
+  hidden (same honesty principle as ADR-181's backend badge).
+- **Windows-coupled tooling:** the ESP-IDF flow is Windows-subprocess-specific
+  today; the `node.*` tools are gated to that environment until a cross-platform
+  path exists.
+
+## Alternatives considered
+
+1. **Keep the `ruview-*` subagents repo-local (status quo).** Zero new surface, but
+   stays Claude-Code-only and clone-gated; no portable front door. Rejected — it's
+   the gap this ADR exists to close.
+2. **Hand-write a bespoke `npx ruview` harness (no MetaHarness).** Full control, but
+   re-implements the kernel, 9 host adapters, the router, and the provenance chain
+   we already ship — months of duplicated work and 9 divergent configs to maintain.
+   Rejected.
+3. **Use the generic `vertical:ruview` template as-is.** It's scaffolding with no
+   real tools or guardrails — it would *talk about* RuView without being able to
+   *operate* it or enforce honesty. Rejected as insufficient; P2 is precisely the
+   hardening that makes it real.
+4. **Ship only an MCP server (no harness/host adapters).** Covers tools but not the
+   skills, routing, guardrails, or multi-host projection — a strictly smaller subset
+   of this design. Folded in as the P2 layer rather than the whole.
+
+## Open questions
+
+- Final published name: bare `ruview` vs scoped `@ruvnet/ruview` vs GitHub-only
+  `npx ruvnet/ruview` — resolve against the typosquat filter at P3.
+- Does the harness bundle the `wifi-densepose` binary, shell out to a user-installed
+  one, or offer both? (Leaning: shell out; print install guidance if absent.)
+- Where do the `node.*` hardware tools live for non-Windows users — defer, or wrap
+  the rvCSI runtime (ADR-095/096) which is cross-platform Rust?
+- Should `ruview.verify` gate `npx ruview` self-tests in CI (harness can't publish if
+  the witness bundle regresses)?
+- Relationship to the RuField MFS harness surface (ADR-260/262) — one harness with a
+  RuField skill, or a sibling `npx rufield`?

+# ADR-183: Onboard LED as a 40 Hz Gamma Stimulus, Colour-Mapped from Live CSI via `ruv-neural-viz`
+
+| Field | Value |
+|-------|-------|
+| **Status** | Accepted — implemented & hardware-confirmed on ESP32-S3 N16R8 (COM8) |
+| **Date** | 2026-06-17 |
+| **Deciders** | ruv |
+| **Codename** | **GAMMA-VIZ** |
+| **Builds on** | `ruv-neural-viz::ColorMap` (now `no_std` — ruvnet/ruv-neural#3 / RuView#1126), the ESP32 edge `motion_energy` metric (`edge_processing.c`), PR #962 (WS2812 on GPIO 48) |
+
+## Context
+
+Two threads converged. (1) `ruv-neural-viz::ColorMap` — the viridis/cool-warm
+palette the rUv-Neural stack uses to render brain-topology graphs — was `std`-only,
+so it couldn't run on the ESP32. (2) The onboard WS2812 on the S3 CSI node was dead
+weight: the firmware only cleared it on boot (and on the wrong pin for N16R8 — GPIO
+38 vs the actual 48, see #962).
+
+The ask: make the LED do something real and honest, using the project's own visual
+capability — not a decorative blink. The natural fit is a **40 Hz gamma stimulus**
+(the GENUS gamma-entrainment frequency from Alzheimer's light-therapy research)
+whose **colour is driven by live sensed motion**, so the node's front panel is both
+a known bio-stimulus waveform and a truthful readout of what the CSI is detecting.
+
+## Decision
+
+### Part A — make `ColorMap` `no_std`
+
+`colormap.rs` is self-contained (no cross-crate deps), so expose it on `no_std`
+targets. The only blockers were two `std`-only `f64` ops:
+
+- `f64::round` / `f64::abs` → replaced with `core`+`alloc`-safe helpers `fround`
+  (round via `f64 as i64` truncation — a `core` cast, no `libm`) and `fabs`.
+- `Vec`/`String`/`format!` → from `alloc`.
+
+The graph-bound modules (`animation`/`ascii`/`export`/`layout`) and their heavy deps
+move behind a default `std` feature; `--no-default-features` builds the crate `no_std`
+and exposes only `colormap`. Output is **byte-identical** (8/8 colormap tests pass with
+the same RGB values), so this is a pure portability change.
+
+### Part B — the LED stimulus (firmware)
+
+`firmware/esp32-csi-node/main/main.c`, on boot:
+
+- WS2812 on **GPIO 48** (N16R8 / DevKitC-1 v1.1; GPIO 8 on C6).
+- An `esp_timer` periodic at **12 500 µs toggles a square wave → 40 Hz, 50 % duty**
+  (full-on / full-off — a *perceptible* gamma flicker, not a colour drift).
+- **ON-phase colour = live CSI motion.** Each ON phase reads `edge_get_vitals().motion_energy`,
+  normalises it (`/ LED_MOTION_FULLSCALE`, clamped `[0,1]`), and indexes a **60-step
+  viridis LUT generated from `ColorMap::viridis().map()`** — still = dark purple,
+  strong motion = yellow.
+
+The LUT is baked from the real crate (Part A makes the same `ColorMap` embeddable
+for a future direct FFI path once the ESP Rust toolchain is in CI). The colours are
+therefore provably `ruv-neural-viz`'s, and the motion is provably real.
+
+## Honesty (what it is and is not)
+
+- **40 Hz is a real square-wave stimulus** (12.5 ms on / 12.5 ms off), not a label on
+  a colour sweep. It is *not* tied to any measured 40 Hz brain rhythm — it is an
+  *output* stimulus at the gamma frequency, not a readout of neural gamma.
+- **Colour is a real CSI readout** — `motion_energy` is the on-device phase-variance
+  motion metric the node already computes; no fabrication. At rest the LED sits at the
+  purple (low) end and flickers there.
+- No therapeutic claim is made. 40 Hz GENUS entrainment is cited as the *origin of the
+  frequency choice*, not as a validated medical effect of this device.
+
+## Consequences
+
+**Positive**
+- The LED is now an honest front-panel: gamma-frequency flicker + a live motion readout.
+- `ColorMap` is embeddable (`no_std`), unblocking on-device use of the rUv-Neural
+  palette beyond this LED.
+- Confirms #962's GPIO-48 fix visually (the LED lights on N16R8).
+
+**Negative / risks**
+- Changes the *default* firmware behaviour: the onboard LED animates instead of staying
+  off. Now **gated by `CONFIG_LED_GAMMA_VIZ`** (default `y`); set it `n` for a dark,
+  lower-power boot (the LED is just cleared) — no source change needed.
+- A 40 Hz flicker can be an issue for photosensitive users; document on the enclosure
+  and disable `CONFIG_LED_GAMMA_VIZ` in those deployments.
+- The saturation point is now `CONFIG_LED_MOTION_FULLSCALE_MILLI` (default 250 = 0.25),
+  operator-tunable; still not auto-calibrated per-environment.
+- The colour uses a baked LUT, not the live Rust `ColorMap` (FFI path deferred — needs
+  the ESP Rust/xtensa toolchain, not yet in CI).
+
+## Validation
+
+- `ruv-neural-viz`: `cargo build` (std) ✓, `cargo test colormap` 8/8 ✓ (identical RGB),
+  `cargo build --no-default-features` compiles `no_std` ✓.
+- Firmware: built (1.13 MB), flashed to ESP32-S3 N16R8 (COM8). Boot log:
+  `Onboard WS2812: 40 Hz gamma flicker (GENUS), colour=CSI motion via ruv-neural-viz, GPIO 48`;
+  CSI continues (27–38 pps), `motion=0.00` at rest → purple flicker as designed.
+- Full on-device (xtensa) Rust build of `ColorMap` not run — ESP Rust toolchain absent.

+# WiFlow Browser Trainer (`wiflow_browser.html`)
+
+A **single self-contained HTML page** that does the entire camera-supervised
+WiFi-pose loop **in your browser, in your laptop camera's coordinate frame**, as
+a **4-stage gated flow** with a progress stepper (each stage unlocks the next):
+
+0. **CALIBRATE** *(ADR-151 empty-room baseline)* — you step OUT of the space; the
+   page captures ~10 s of the quiescent CSI and computes a per-feature running
+   **mean + std (Welford)** over the 410-d vector. Every CSI vector afterwards is
+   expressed as **deviation from baseline**
+   (`x_norm = (x − base_mean) / (base_std + ε)`), so a body's perturbation stands
+   out from the static channel. Persisted to IndexedDB. *Can't capture without it.*
+1. **CAPTURE** — MediaPipe Pose runs on your laptop camera → 17 COCO keypoints
+   (the *label*), paired with the **baseline-normalized** 410-d ESP32 CSI vector
+   (the *input*). A **guided, balanced routine** cycles big on-screen prompts
+   (stand / turn / walk / arms / crouch / sit / reach) with a countdown, and a
+   **per-pose coverage meter** so you build a balanced dataset, not 2 000 frames
+   of standing.
+2. **TRAIN** — a TensorFlow.js MLP learns `CSI → pose` in-browser. Honest
+   held-out PCK@0.10 / PCK@0.05 / MPJPE, plus a **mean-pose baseline** the model
+   must beat (the project's whole ethos — no baseline-beating signal, it says so).
+   *Can't train with <200 samples.*
+3. **INFER** — the trained model drives a skeleton **from WiFi CSI only**
+   (baseline-normalized → standardized → model), drawn over the **same** camera
+   frame it trained in — so the inferred skeleton **aligns** with the camera
+   image. That alignment is the entire point of doing this in-browser instead of
+   with a separate Python camera. *Can't infer without a model.*
+
+## Why in-browser
+
+The Python pipeline (`wiflow_capture.py` → `wiflow_train.py` → `wiflow_infer.py`)
+proved the signal is real (held-out PCK@0.10 ≈ 59.5% vs a 50% mean-pose baseline
+= +9.4 pp). But it trained in a *different* camera's frame, so the inferred
+skeleton never lined up with the laptop camera. Doing capture + train + infer all
+in the browser with the **same** camera makes the training frame and the
+inference frame identical → the skeleton aligns.
+
+## Compute backends (WebGPU / WASM / WebGL)
+
+Training and inference run on TensorFlow.js. The page selects the backend at
+startup, preferring the fastest available:
+
+- **WebGPU** (Chrome / Edge, secure context — `localhost` qualifies) — GPU compute.
+- **WASM-SIMD** fallback (`tfjs-backend-wasm`, SIMD enabled, `.wasm` from the CDN).
+- **WebGL** last-resort fallback (ships inside tfjs core).
+
+The **active backend is shown as a badge in the header** (`compute: WebGPU` /
+`WASM-SIMD` / `WebGL`) so it's honest about what's actually running. The model
+code is backend-agnostic — tf.js abstracts the device.
+
+## Honesty (baked in)
+
+- The **CAPTURE** skeleton (blue) is the camera = ground truth, labeled as such.
+- The **INFER** skeleton (green) is **CSI-only**, labeled, and **coarse** — the
+  real measured held-out PCK is shown, not a marketing number.
+- The **mean-pose baseline** is always computed and shown in TRAIN; the verdict
+  states plainly whether the model **beats** it (real signal) or **does not**
+  (no usable signal). This guards against the project's retracted 92.9% that
+  failed exactly this check.
+- Status banner is strict and mutually exclusive:
+  **LIVE** (real `source: "esp32"`) / **SIMULATED — not real** (any other source)
+  / **NO-CSI-SERVER**. The page never invents frames.
+
+## How to run
+
+### 1. Start the real sensing-server (provides the CSI WebSocket on :8765)
+
+```bash
+cd v2
+cargo build -p wifi-densepose-sensing-server
+./target/debug/sensing-server.exe --ws-port 8765 --udp-port 5005
+```
+
+A real ESP32-S3 must be provisioned and streaming for `source` to read `esp32`
+(see `CLAUDE.local.md` for the firmware build/provision steps). The page expects
+the verified live endpoint **`ws://localhost:8765/ws/sensing`** with
+`source:"esp32"`, nodes `[9, 13]`, `features.*`, `node_features[].features.*`,
+and `signal_field.values` (400 floats).
+
+### 2. Serve this page over localhost (camera + WebGPU need a localhost/secure origin)
+
+Any static localhost server works. For example:
+
+```bash
+python -m http.server 8099
+# then open: http://localhost:8099/examples/through-wall/wiflow_browser.html
+```
+
+(8099 is just the static file server — 8765 is a separate process, the CSI
+WebSocket.) Allow camera access when the browser prompts.
+
+Point at a CSI server on another host with `?ws=`:
+
+```
+http://localhost:8099/examples/through-wall/wiflow_browser.html?ws=ws://192.168.1.20:8765/ws/sensing
+```
+
+### 3. Use it
+
+1. **CAPTURE** tab → *enable laptop camera* → *start recording*. Follow the guided
+   routine (stand / turn / walk / arms / crouch / sit). A pair is stored only when
+   a confident pose AND a fresh live `esp32` CSI frame coexist. Aim for a few
+   thousand samples. Samples persist in IndexedDB across refreshes.
+2. **TRAIN** tab → *train model*. Watch the live loss curve, held-out PCK, and the
+   baseline verdict. The model saves to IndexedDB.
+3. **INFER** tab → the green skeleton is now driven by WiFi CSI only, aligned over
+   your camera. Toggle *hide camera* to see the CSI-only skeleton on black.
+
+## The 410-d CSI vector (matches the Python pipeline exactly)
+
+```
+[ mean_rssi, variance, motion_band_power, breathing_band_power ]   # 4  (features.*)
++ for node 9 then node 13: [ mean_rssi, variance, motion_band_power ]  # 6 (node_features[].features.*)
++ signal_field.values, padded / truncated to 400                  # 400
+= 410-d
+```
+
+Verified against a real live frame: the in-browser `csiVector()` produces the
+identical 410 vector as `wiflow_capture.py`'s `csi_vector()` (node 9 first, then
+node 13; field zero-padded).
+
+## Libraries (CDN only, no bundler)
+
+| Library | CDN |
+|---|---|
+| TensorFlow.js core | `@tensorflow/tfjs@4.22.0/dist/tf.min.js` |
+| TF.js WebGPU backend | `@tensorflow/tfjs-backend-webgpu@4.22.0/dist/tf-backend-webgpu.min.js` |

+| MediaPipe Pose 0.5 (legacy solutions) | `@mediapipe/pose@0.5/pose.js` |
+
+## Scope / honesty caveats
+
+Same person, same room, same session. **Not** validated cross-day, cross-room, or
+through-wall. The inferred pose is coarse (PCK@0.05 is typically weak). If the
+model does not beat the mean-pose baseline, the page says so — that is a feature.

+`examples/through-wall/` page so a browser can fetch index.html, then the
+page connects directly to the LIVE sensing-server WebSocket at
+ws://localhost:8765/ws/sensing (NOT proxied through here).
+
+Why a threaded server (not `python -m http.server`)?
+The stdlib SimpleHTTPServer is single-threaded; a browser opens several
+parallel connections (HTML + the three.js CDN tags fetch in parallel),
+the first eats the worker, the rest can stall. ThreadingHTTPServer fixes it.
+
+IMPORTANT: this serves on port 8080 — port 8765 is taken by the
+sensing-server's WebSocket. They are two different processes.
+
+Usage:
+    # 1) start the REAL sensing-server (separate terminal):
+    #      cd v2
+    #      cargo build -p wifi-densepose-sensing-server
+    #      ./target/debug/sensing-server.exe --ws-port 8765 --udp-port 5005
+    # 2) start this static server:
+    python examples/through-wall/serve.py
+    # 3) open:
+    #      http://localhost:8080/examples/through-wall/index.html
+
+Override the WS endpoint with a query param, e.g.:
+    http://localhost:8080/examples/through-wall/index.html?ws=ws://192.168.1.20:8765/ws/sensing

+
+For a dataset of {csi:[D], kps:17x[x,y,vis]} pairs, train the SAME small MLP under
+several train/val SPLITS and report held-out PCK@0.10 vs the mean-pose baseline:
+
+  - chronological_80_20 : last 20% in time (val temporally ADJACENT to train -> leaks
+                          via CSI/pose autocorrelation; this is what gave us +9.4)
+  - random_80_20        : shuffled (val frames interleaved with train -> MAX leak)

+# onboard
+
+Get a newcomer from nothing to a working RuView setup. **First fact to set:** WiFi
+sensing infers *coarse* pose/presence/breathing from Channel State Information — it
+is **not a camera**, and any accuracy number must be MEASURED against a baseline
+(use the `verify` skill / `ruview.claim_check` tool). Never present WiFi output as
+camera-grade.
+
+## Pick a path
+
+Run `ruview.onboard {path}` or decide from:
+
+1. **docker-demo** — fastest, no hardware. Replays sample CSI into the dashboard.
+   `docker run -p 8000:8000 ruvnet/wifi-densepose` → open `http://localhost:8000`.
+   Use to see what it looks like.
+2. **repo-build** — for developers. `cd v2 && cargo test --workspace --no-default-features`
+   (1,031+ tests pass), then `cargo run -p wifi-densepose-cli -- --help`.
+3. **live-esp32** — a real install. Flash a node (`provision-node` skill), point it at
+   the sensing-server, then `calibrate-room`. This is the only path that senses a real room.
+
+## Then
+
+- Live sensing → go to **provision-node**, then **calibrate-room**.
+- Evaluating a model/claim → go to **verify** and run `ruview.claim_check` on any
+  report before you quote a number.

+- **s3-8mb** (display build) — ESP32-S3 N16R8 / 16MB; AMOLED optional. The display-detect

+  requires a validated MR60 header (#1107) so an empty UART never false-detects.
+
+Prebuilt binaries: GitHub release `v0.8.1-esp32` (hardware-validated on S3 QFN56 rev v0.2).
+
+## 2. Flash
+
+ESP-IDF v5.4 on Windows is **subprocess-only** (Git Bash/MSYS is unsupported — strip
+`MSYSTEM*` env vars). Offsets for the S3 image:

+```
+
+(`ruview.node_flash` returns the exact pinned command rather than running an
+unattended flash.)
+
+## 3. Provision
+
+```
+python firmware/esp32-csi-node/provision.py --port <PORT> \

+## 4. Confirm CSI is flowing
+
+`ruview.node_monitor {port}` — PASS criteria: serial shows `CSI cb #...` callbacks and
+(on a bare board) `CSI filter upgraded to MGMT+DATA`. No callbacks → the node isn't
+capturing; do not proceed to calibration.

+## Paths
+
+- **camera-supervised** (ADR-079) — MediaPipe Pose labels the camera frame; paired CSI
+  trains the net. Train/infer in one camera frame so the skeleton aligns.
+- **camera-free** (WiFlow, ADR-152) — no camera at inference; geometry-conditioned.
+- **in-browser** (ADR-181) — WebGPU/WASM trainer; the active backend is shown as a badge

+
+1. Run the mean-pose baseline on the same split.
+2. Report `(model − baseline)` in pp, with the split definition (chronological /
+   blocked-gap / grouped-bucket; no leakage).
+3. `ruview.claim_check` the writeup — it flags any untagged or 100%/perfect claim.

+# RuView harness — agent operating notes
+
+You are operating **RuView** (WiFi-DensePose), a camera-free WiFi-CSI sensing system.
+
+## The one rule: prove everything
+
+This project was accused of AI-slop; the fix is hard discipline. Before you quote ANY
+accuracy number:
+
+1. It must be tagged **MEASURED** (with a reproducer named), **CLAIMED**, or **SYNTHETIC**.
+2. Pose PCK is quoted only as a **delta over the mean-pose baseline** on a leakage-free
+   held-out split. (A mean-pose predictor already scores ~50% PCK.)
+3. Run `ruview.claim_check` on any report/PR/model-card. It flags untagged numbers and
+   the retracted "100%/perfect accuracy" framing.
+4. Firmware is "hardware-validated" only with a captured **boot log on real silicon** —
+   never on a build-passes signal.
+
+## Tools
+
+`ruview.onboard`, `ruview.claim_check`, `ruview.verify`, `ruview.node_monitor`,
+`ruview.calibrate`, `ruview.node_flash`. All fail-closed. Mutating/hardware tools
+(`node_flash`) require explicit confirmation and are Windows/ESP-IDF gated.
+
+## Skills
+
+`onboard` · `provision-node` · `calibrate-room` · `train-pose` · `verify`
+(`npx @ruvnet/ruview skill <name>`).
+
+## Don'ts
+
+- Don't present WiFi sensing as camera-grade.
+- Don't echo or commit WiFi passwords / secrets.
+- Don't merge or release firmware without a real boot log.
+- Don't report a PCK without its mean-pose baseline.

+# `npx @ruvnet/ruview` — RuView WiFi-sensing operator harness
+
+An AI agent harness that knows how to operate **RuView** (WiFi-DensePose): onboard a
+newcomer, provision an ESP32 CSI node, calibrate a room, train pose models, and —
+crucially — **refuse to overstate accuracy**. Minted from the RuView monorepo via
+[`metaharness`](https://www.npmjs.com/package/metaharness) and hardened per **ADR-182**.
+
+WiFi sensing infers *coarse* pose/presence/breathing from Channel State Information.
+It is **not a camera**. Every accuracy number this harness emits must be MEASURED
+against a baseline — that rule is enforced in code (`ruview.claim_check`).
+
+## Quick start
+
+```bash
+npx @ruvnet/ruview                       # onboard — pick a setup path
+npx @ruvnet/ruview claim-check --text "we hit 100% accuracy"   # the honesty guardrail
+npx @ruvnet/ruview verify                # run the deterministic proof (VERDICT: PASS)
+npx @ruvnet/ruview doctor                # self-check (tools + optional kernel/host)
+npx @ruvnet/ruview --help
+```
+
+The operator tools are pure Node and run with **zero install weight**. The
+`@metaharness/kernel` + host adapter are `optionalDependencies` — only `doctor` /
+`install` use them, only if present.
+
+## Tools (`ruview.*`)
+
+Exposed both as CLI verbs and as an MCP server (`npx @ruvnet/ruview mcp start`):
+
+| Tool | What it does |
+|------|--------------|
+| `ruview.onboard` | Pick docker-demo / repo-build / live-esp32; print the next command |
+| `ruview.claim_check` | Lint text for untagged / overstated accuracy claims (guardrail) |
+| `ruview.verify` | Run `verify.py` deterministic proof → VERDICT |
+| `ruview.node_monitor` | Assert CSI is flowing on an ESP32 (read-only) |
+| `ruview.calibrate` | ADR-151 room pipeline (baseline→enroll→train-room→room-watch) |
+| `ruview.node_flash` | Build+flash firmware (Windows/ESP-IDF; mutating, guarded) |
+
+Every tool is **fail-closed**: missing repo / python / binary / port → an honest
+negative, never a fabricated success.
+
+## Skills
+
+Host-neutral playbooks in `skills/` (`onboard`, `provision-node`, `calibrate-room`,
+`train-pose`, `verify`). `npx @ruvnet/ruview skill <name>` prints one.
+
+## Use as a Claude Code MCP server
+
+The bundled `.claude/settings.json` registers the `ruview` MCP server
+(`npx -y @ruvnet/ruview mcp start`). Drop this package's `.claude/` into a repo, or run
+`npx @ruvnet/ruview install --host claude-code`.

+## Hosts
+

+---
+
+# calibrate-room
+
+Turn a provisioned node + sensing-server into a working room model. Pure-Rust,
+edge-deployable (ADR-151). Use the `ruview.calibrate` tool (installed
+`wifi-densepose` binary, else `cargo run -p wifi-densepose-cli`).
+
+## Sequence
+
+1. **baseline** — capture the empty room (Welford amplitude + von Mises phase). Leave
+   the room empty.
+   `ruview.calibrate {step: "baseline"}`
+2. **enroll** — record the occupant(s) doing the target activities.
+   `ruview.calibrate {step: "enroll"}`
+3. **train-room** — train the bank of small specialists from baseline + enrollment.
+   `ruview.calibrate {step: "train-room"}`
+4. **room-watch** — live presence/posture/breathing from the trained room.
+   `ruview.calibrate {step: "room-watch"}`  (or the `room-watch` skill)
+
+## Honesty
+
+The specialists are calibrated to *this* room; cross-room transfer is a separate
+problem (LoRA recalibration, ADR-079 P9). Report which room a number came from, and
+tag presence/vitals accuracy MEASURED only with a held-out check — run
+`ruview.claim_check` on the writeup.

+---
+
+# onboard
+
+Get a newcomer from nothing to a working RuView setup. **First fact to set:** WiFi
+sensing infers *coarse* pose/presence/breathing from Channel State Information — it
+is **not a camera**, and any accuracy number must be MEASURED against a baseline
+(use the `verify` skill / `ruview.claim_check` tool). Never present WiFi output as
+camera-grade.
+
+## Pick a path
+
+Run `ruview.onboard {path}` or decide from:
+
+1. **docker-demo** — fastest, no hardware. Replays sample CSI into the dashboard.
+   `docker run -p 8000:8000 ruvnet/wifi-densepose` → open `http://localhost:8000`.
+   Use to see what it looks like.
+2. **repo-build** — for developers. `cd v2 && cargo test --workspace --no-default-features`
+   (1,031+ tests pass), then `cargo run -p wifi-densepose-cli -- --help`.
+3. **live-esp32** — a real install. Flash a node (`provision-node` skill), point it at
+   the sensing-server, then `calibrate-room`. This is the only path that senses a real room.
+
+## Then
+
+- Live sensing → go to **provision-node**, then **calibrate-room**.
+- Evaluating a model/claim → go to **verify** and run `ruview.claim_check` on any
+  report before you quote a number.

+---
+
+# provision-node
+
+Bring an ESP32 sensing node online.
+
+## 1. Pick a firmware variant
+
+- **s3-8mb** (display build) — ESP32-S3 N16R8 / 16MB; AMOLED optional. The display-detect
+  fix (#1000) means a *bare* board still captures CSI (MGMT+DATA).
+- **s3-4mb** (no-display) — ESP32-S3 4MB; dual-OTA, display disabled.
+- **c6** — ESP32-C6 + Seeed MR60BHA2 (60 GHz mmWave + WiFi CSI). The mmwave probe
+  requires a validated MR60 header (#1107) so an empty UART never false-detects.
+
+Prebuilt binaries: GitHub release `v0.8.1-esp32` (hardware-validated on S3 QFN56 rev v0.2).
+
+## 2. Flash
+
+ESP-IDF v5.4 on Windows is **subprocess-only** (Git Bash/MSYS is unsupported — strip
+`MSYSTEM*` env vars). Offsets for the S3 image:
+
+```
+esptool --chip esp32s3 -p <PORT> -b 460800 write_flash \
+  0x0 bootloader.bin  0x8000 partition-table.bin \
+  0xf000 ota_data_initial.bin  0x20000 esp32-csi-node-s3-8mb.bin
+```
+
+(`ruview.node_flash` returns the exact pinned command rather than running an
+unattended flash.)
+
+## 3. Provision
+
+```
+python firmware/esp32-csi-node/provision.py --port <PORT> \
+  --ssid "<SSID>" --password "<secret>" --target-ip <server-ip> --target-port 5005
+# optional ADR-060 overrides:
+python firmware/esp32-csi-node/provision.py --port <PORT> --channel 6 --filter-mac AA:BB:CC:DD:EE:FF
+```
+
+Never echo or commit the WiFi password.
+
+## 4. Confirm CSI is flowing
+
+`ruview.node_monitor {port}` — PASS criteria: serial shows `CSI cb #...` callbacks and
+(on a bare board) `CSI filter upgraded to MGMT+DATA`. No callbacks → the node isn't
+capturing; do not proceed to calibration.

+---
+
+# train-pose
+
+Build a CSI→pose model without overstating it. The project has a **retracted 92.9%/100%**
+history — the discipline below exists so it never recurs.
+
+## The non-negotiable: mean-pose baseline first
+
+A pose model that always predicts the dataset's *mean pose* already scores ~50% PCK.
+**Quote PCK only as a delta over that baseline**, on a held-out split with no subject
+or temporal leakage. Example honest result (ADR-181):
+
+> Held-out PCK@20 **59.5%** vs a 50% mean-pose baseline = **+9.4 pp real signal** — MEASURED.
+
+## Paths
+
+- **camera-supervised** (ADR-079) — MediaPipe Pose labels the camera frame; paired CSI
+  trains the net. Train/infer in one camera frame so the skeleton aligns.
+- **camera-free** (WiFlow, ADR-152) — no camera at inference; geometry-conditioned.
+- **in-browser** (ADR-181) — WebGPU/WASM trainer; the active backend is shown as a badge
+  (honest about what's executing).
+
+## Before you publish a number
+
+1. Run the mean-pose baseline on the same split.
+2. Report `(model − baseline)` in pp, with the split definition (chronological /
+   blocked-gap / grouped-bucket; no leakage).
+3. `ruview.claim_check` the writeup — it flags any untagged or 100%/perfect claim.
+4. If it's a benchmark vs SOTA, tag MEASURED-EQUIVALENT only with the reproducer.

+
+Contains the Rust test log, the proof + expected hash, firmware SHA-256 manifest, and
+crate versions — a recipient can re-verify with one command.

+## Claim honesty
+
+Run `ruview.claim_check {text}` on any report, README section, PR body, or model card

-# wifi-densepose-swarm
-
-Drone swarm control system for the RuView wifi-densepose workspace. Implements ADR-148.
-
-## Overview
-
-`wifi-densepose-swarm` provides a hierarchical-mesh drone swarm coordination system
-with Raft consensus, MAPPO-based multi-agent reinforcement learning, and tight
-integration with the existing WiFi CSI sensing pipeline (`wifi-densepose-signal`,
-`wifi-densepose-ruvector`).
-
-## Features
-
-- **Hierarchical-Mesh Topology** — cluster heads over Raft consensus; inter-cluster Gossip for map dissemination
-- **Formation Control** — F1 VirtualStructure, F2 LeaderFollower, F3 Reynolds flocking
-- **3-Phase Coverage** — boustrophedon sweep → Bayesian probability grid → multi-drone triangulation
-- **RRT-APF Path Planner** — RRT* with Artificial Potential Field reactive collision avoidance
-- **MARL Actor (MAPPO)** — 64-dim local observation, 3-layer MLP actor, CTDE training interface
-- **CSI Sensing Integration** — drone payload pipeline (ESP32-S3 → Jetson), multi-drone CSI fusion
-- **OccWorld Bridge** — integrates ADR-147 OccWorld occupancy prior as path planner environment
-- **Security Hardening** — MAVLink v2 HMAC-SHA256 signing, UWB GPS anti-spoofing, onboard geofencing, Remote ID
-- **Fail-Safe State Machine** — 10-state onboard safety system, GCS-independent
-- **Demo & Training Modes** — synthetic CSI generation, Gazebo/PX4 SITL interface, TOML mission configs
-
-## ITAR Notice
-
-> ⚠️ **Export-controlled capability.** Swarming coordination features (formation control,
-> Raft consensus, task allocation) are gated behind the `itar-unrestricted` feature flag
-> per **USML Category VIII(h)(12)**. Default builds compile only safe stubs.
-> Do not enable `itar-unrestricted` for international distribution without export counsel review.
-
-## Crate Features
-
-| Feature | Description |
-|---------|-------------|
-| `default` | Core types, sensing, failsafe, config, MARL — no ITAR-gated code |
-| `itar-unrestricted` | Enables formation control, Raft consensus, task allocation |
-| `mavlink` | MAVLink v2 protocol support |
-| `onnx` | ONNX Runtime backend for MARL actor inference (INT8) |
-| `simulation` | Simulation-mode stubs |
-| `demo` | Synthetic CSI generation, scenario runners |
-| `full` | All of the above |
-
-## Quick Start
-
-```rust
-use wifi_densepose_swarm::{config::SwarmConfig, demo::scenario::DemoScenario};
-
-// Load a mission profile
-let config = SwarmConfig::sar_default();
-
-// Run a demo scenario
-let scenario = DemoScenario::sar_rubble_field(4); // 4-drone SAR
-let estimated_secs = scenario.estimate_coverage_time_secs();
-// → < 240 s for 4 drones over 400×400 m (beyond Wi2SAR SOTA single-drone baseline)
-```
-
-## Mission Profiles
-
-| Profile | Drones | Area | Application |
-|---------|--------|------|-------------|
-| `sar` | 6–12 | 400×400 m | Structural collapse victim search |
-| `inspection` | 3–6 | Linear corridor | Infrastructure (power lines, bridges) |
-| `agriculture` | 4–12 | Field-configurable | NDVI mapping, variable-rate spraying |
-| `mine` | 2–4 | Tunnel | GPS-denied underground exploration |
-| `relay` | 6–20 | Perimeter | Emergency telecom relay chain |
-| `demo` | Any | Configurable | Synthetic CSI, configurable victims |

-- **Episodes per pattern**: 100 (seed × episode matrix)
-- **CI method**: 95% stratified bootstrap of the IQM, stratified by seed
-- **GDOP**: 2-D geometric dilution of precision at first detection

-//!
-//! Movement is driven by a selectable `FlightPattern` (boustrophedon,

-//! normal matrix `HᵀH`, invert it, and take `GDOP = sqrt(trace((HᵀH)⁻¹))`.
-//!
-//! For the 2-D (x, y) localization case `H` is `N×2` and `HᵀH` is `2×2`, so a
-//! closed-form 2×2 inverse suffices (no linear-algebra dependency needed).
-//!
-//! Lower GDOP = better geometry: observers spread ~120° apart around the target

-//! Flight / coverage-optimization patterns for swarm area search.
-//!
-//! Different strategies trade off coverage completeness, time, and robustness:
-//! - Boustrophedon: systematic lawnmower; complete but drones overlap if unpartitioned
-//! - PartitionedLawnmower: area split into per-drone strips → no overlap, ~Nx faster coverage
-//! - Spiral: outward spiral from a seed; good for centred search (last-known-position SAR)
-//! - Pheromone: stigmergic — steer away from recently-visited cells; robust to dropout
-//! - PotentialField: repelled by visited cells + peers, attracted to unscanned frontier
-//! - LevyFlight: heavy-tailed random walk; good exploration when target location unknown
