 ## [Unreleased]

+### Added
+- **Real-time CSI introspection / low-latency tap on `wifi-densepose-sensing-server` (ADR-099).**
+  New `wifi_densepose_sensing_server::introspection` module wires
+  [midstream](https://github.com/ruvnet/midstream)'s `temporal-attractor` (Lyapunov +
+  regime classification) and `temporal-compare` (DTW pattern matching) as a
+  **parallel tap** alongside RuView's existing event pipeline — no replacement,
+  no behaviour change to the existing `/ws/sensing` fan-out or `wifi-densepose-signal`
+  DSP. Two new endpoints (off by default, enabled via `--introspection`):
+  - `GET /ws/introspection` — newline-delimited JSON snapshots streamed at the CSI
+    frame rate. Each snapshot carries `frame_count`, `regime` (Idle / Periodic /
+    Transient / Chaotic / Unknown), `lyapunov_exponent`, `attractor_dim`,
+    `attractor_confidence`, `regime_changed` (boolean — flips on the first frame
+    after a regime transition), and `top_k_similarity[]` (highest-scoring
+    signature matches against a per-deployment library).
+  - `GET /api/v1/introspection/snapshot` — single-shot JSON snapshot, auth-gated
+    when `RUVIEW_API_TOKEN` is set.
+  Per-frame `update()` budget measured at **0.041 ms p99** on the I5 bench
+  (~24× under ADR-099 D4's 1 ms target). Shape-match latency on a 1-D
+  mean-amplitude L1 stand-in: **5 frames** (3.20× ratio vs the 16-frame event-path
+  floor). ADR-099 D8 honestly amended — the aspirational 10× bar is contingent on
+  ADR-208 Phase 2 multi-dim NPU embeddings; this release ships the tap off-by-default
+  while the foundation lands. 8 lib tests + 5 latency/regression tests (`tests/introspection_latency.rs`,
+  including a 200-frame noise warm-up → 10-frame motion-ramp signature benchmark).
+- **Opt-in bearer-token auth on `wifi-densepose-sensing-server`'s `/api/v1/*` HTTP surface (closes #443).**
+  New `wifi_densepose_sensing_server::bearer_auth` module: when the
+  `RUVIEW_API_TOKEN` env var is set, every request whose path begins with
+  `/api/v1/` must carry an `Authorization: Bearer <token>` header (constant-time
+  compared) or the server responds `401 Unauthorized`. When the variable is
+  unset or empty the middleware is a no-op — the long-standing LAN-only
+  deployment posture is preserved, so this is a binary deployment-time switch
+  with **no default behaviour change**. `/health*`, `/ws/sensing`, and the
+  `/ui/*` static mount are intentionally never gated (orchestrator probes +
+  local browsers). Startup logs which mode is active and warns when auth is on
+  with a `0.0.0.0` bind. 8 unit tests on the middleware (lib test count 191 → 199).
+  Resolves the security audit raised in #443.
+
+### Changed
+- **Docker image: build-time guard for the UI assets, plus a CI workflow that
+  rebuilds and pushes on every change (closes #520, #514).** `docker/Dockerfile.rust`
+  now `RUN`s a guard after `COPY ui/` that fails the build if any of
+  `index.html` / `observatory.html` / `pose-fusion.html` / `viz.html` / the
+  `observatory/` / `pose-fusion/` / `components/` / `services/` directories are
+  missing, so a stale image can never be silently produced again. New
+  `.github/workflows/sensing-server-docker.yml` builds the image on push to
+  `main` (paths-filtered) and on `v*` tags and pushes to both
+  `docker.io/ruvnet/wifi-densepose` and `ghcr.io/ruvnet/wifi-densepose` with
+  `latest` + `vX.Y.Z` + `sha-<short>` tags, then smoke-tests the published
+  artifact: `/health`, `/api/v1/info`, the observatory + pose-fusion UI assets,
+  and the `RUVIEW_API_TOKEN` auth path (no token → 401, wrong → 401, correct
+  → 200). Uses `DOCKERHUB_USERNAME` / `DOCKERHUB_TOKEN` repo secrets for the
+  Docker Hub push; ghcr.io uses the workflow's `GITHUB_TOKEN`.
+- **rvCSI moved to its own repo and is now vendored as a submodule.** The 9 `rvcsi-*`
+  crates (`rvcsi-core`/`-dsp`/`-events`/`-adapter-file`/`-adapter-nexmon`/`-ruvector`/
+  `-runtime`/`-node`/`-cli` — added inline in #542) now live in
+  [`github.com/ruvnet/rvcsi`](https://github.com/ruvnet/rvcsi): published to crates.io
+  as `rvcsi-* 0.3.x`, to npm as `@ruv/rvcsi`, with a Claude Code plugin marketplace and
+  a RuView-style README. RuView vendors it under `vendor/rvcsi` (alongside
+  `vendor/ruvector` / `vendor/midstream` / `vendor/sublinear-time-solver`) and no longer
+  carries inline copies in `v2/crates/`; consumers depend on the published crates (or the
+  submodule's `crates/rvcsi-*` paths). `v2/Cargo.toml`, `CLAUDE.md`, and the README docs
+  table updated accordingly. The ADRs (ADR-095, ADR-096), PRD, and DDD model stay in
+  `docs/` here as the design record of the incubation.
+
+### Fixed
+- **README: corrected the camera-supervised pose-accuracy claim.** The README stated
+  "92.9% PCK@20" for camera-supervised training; that figure does not appear in
+  ADR-079 and is ~2.6× the ADR's own success target (>35% PCK@20). ADR-079 phases
+  P7 (data collection), P8 (training + evaluation on real paired data) and P9
+  (cross-room LoRA) are still `Pending`, so no measured camera-supervised PCK@20 has
+  been published. README now states the proxy-supervised baseline (≈2.5%) and the
+  ADR-079 target (35%+), and notes the eval phases are pending. Surfaced by the
+  PowerPlatePulse training-pipeline audit (2026-05-11); 6 remaining audit findings
+  tracked in the PR.
+- **rvCSI `BaselineDriftDetector`: drift thresholds are now scale-relative, not absolute.**
+  The detector compared `mean_amplitude` against its EWMA baseline with absolute
+  thresholds (`anomaly_threshold = 1.0`, `drift_threshold = 0.15`) — fine for the
+  synthetic unit tests (amplitudes ≈ 1.0), but raw ESP32 CSI is `int8` I/Q with
+  amplitudes up to ~128, so the window-to-window RMS distance is routinely 5–50 ≫ 1.0
+  and `AnomalyDetected` fired on ~96 % of windows (319/331 on a real node-1 capture).
+  Drift is now `‖current − baseline‖₂ / ‖baseline‖₂` (a fraction, with an `eps` floor
+  for a degenerate near-zero baseline), so one tuning works across raw-`int8` ESP32,
+  `int16`-scaled Nexmon, and baseline-subtracted streams alike — `AnomalyDetected`
+  drops to 40/331 on the same data, the existing detector tests still pass, and a
+  `baseline_drift_is_scale_invariant_no_anomaly_storm` regression test was added.
+  ADR-095 D13 / ADR-096 §2.1, §5 updated. Surfaced by an end-to-end test against
+  real ESP32 CSI (a 7,000-frame node-1 capture; transcoder at
+  `scripts/esp32_jsonl_to_rvcsi.py`).
+
+### Added
+- **rvCSI — edge RF sensing runtime (design + first implementation).** New subsystem **rvCSI**: a Rust-first / TypeScript-accessible / hardware-abstracted edge RF sensing runtime that normalizes WiFi CSI from Nexmon, ESP32, Intel, Atheros, file and replay sources into one validated `CsiFrame` schema, runs reusable DSP, emits typed confidence-scored events, and bridges to RuVector RF memory, an MCP tool server and a TS SDK.
+  - **Design docs:** `docs/prd/rvcsi-platform-prd.md` (purpose, users, success criteria, FR1–FR10, NFRs, system architecture, data model); `docs/adr/ADR-095-rvcsi-edge-rf-sensing-platform.md` (the 15 architectural decisions: Rust core, C-at-the-boundary, TS SDK via napi-rs, normalized schema, validate-before-FFI, CSI-as-temporal-delta, RuVector as RF memory, replayability, detection≠decision, local-first, read-first/write-gated MCP, mandatory quality scoring, versioned calibration, plugin adapters); `docs/adr/ADR-096-rvcsi-ffi-crate-layout.md` (crate topology, the napi-c shim record format & contract, the napi-rs Node surface, build/test invariants); `docs/ddd/rvcsi-domain-model.md` (7 bounded contexts: Capture, Validation, Signal, Calibration, Event, Memory, Agent — with aggregates, invariants, context map and domain services). Indexed in `docs/adr/README.md` and `docs/ddd/README.md`.
+  - **Crates** (9 new `v2/crates/rvcsi-*` workspace members): `rvcsi-core` (normalized `CsiFrame`/`CsiWindow`/`CsiEvent` schema, `AdapterProfile`, `CsiSource` plugin trait, id newtypes + `IdGenerator`, `RvcsiError`, the `validate_frame` pipeline + quality scoring; `forbid(unsafe_code)`); `rvcsi-adapter-nexmon` — the **napi-c** seam: `native/rvcsi_nexmon_shim.{c,h}` (the only C in the runtime — allocation-free, bounds-checked, ABI `1.1`), compiled via `build.rs`+`cc`, handling **two byte formats** — the compact self-describing "rvCSI Nexmon record", and the **real nexmon_csi UDP payload** (the 18-byte `magic 0x1111 · rssi · fctl · src_mac · seq · core/stream · chanspec · chip_ver` header + `nsub` int16 I/Q samples, the modern BCM43455c0/4358/4366c0 export read by CSIKit/`csireader.py`), with a Broadcom d11ac **chanspec decoder** (channel/bandwidth/band) — plus a pure-Rust **libpcap reader** (classic `.pcap`, all byte-order/timestamp-resolution magics, Ethernet/raw-IPv4/Linux-SLL link types) and a **Nexmon-chip / Raspberry-Pi-model registry** (`NexmonChip` / `RaspberryPiModel` — including the **Raspberry Pi 5** (CYW43455/BCM43455c0, same wireless as the Pi 4 — 20/40/80 MHz, 2.4+5 GHz, 64/128/256 subcarriers), the Pi 3B+/4/400, and the Pi Zero 2 W (BCM43436b0); `nexmon_adapter_profile` / `raspberry_pi_profile` build the per-chip `AdapterProfile`; `chip_ver` words auto-resolve to a chip). Wrapped by a documented `ffi` module and two `CsiSource`s: `NexmonAdapter` (record buffers) and `NexmonPcapAdapter` (real nexmon_csi UDP inside a `tcpdump -i wlan0 dst port 5500 -w csi.pcap` capture — the pcap timestamp stamps each frame; the chip is auto-detected from `chip_ver`, overridable via `.with_pi_model(Pi5)` / `.with_chip(...)`). `rvcsi-dsp` (DC removal, phase unwrap, smoothing, Hampel/MAD filter, sliding variance, baseline subtraction, motion-energy/presence/confidence features, heuristic breathing-band estimate, non-destructive `SignalPipeline`); `rvcsi-events` (`WindowBuffer`, the `EventDetector` trait + presence/motion/quality/baseline-drift state machines, `EventPipeline`; the baseline-drift detector uses **scale-relative** thresholds — drift as a fraction of the baseline's RMS magnitude — so one tuning works across raw-`int8` ESP32, `int16`-scaled Nexmon, and baseline-subtracted streams alike); `rvcsi-adapter-file` (the `.rvcsi` JSONL capture format, `FileRecorder`, `FileReplayAdapter` deterministic replay); `rvcsi-ruvector` (deterministic window/event embeddings, `cosine_similarity`, the `RfMemoryStore` trait, `InMemoryRfMemory` + `JsonlRfMemory` — a standin until the production RuVector binding); `rvcsi-runtime` (the no-FFI composition layer: `CaptureRuntime` = `CsiSource` + `validate_frame` + `SignalPipeline` + `EventPipeline`, plus one-shot helpers `summarize_capture`/`decode_nexmon_records`/`decode_nexmon_pcap`/`summarize_nexmon_pcap`/`events_from_capture`/`export_capture_to_rf_memory`); `rvcsi-node` — the **napi-rs** seam (a `["cdylib","rlib"]` Node addon, `build.rs` runs `napi_build::setup()`; thin `#[napi]` wrappers over `rvcsi-runtime` — `nexmonDecodeRecords`/`nexmonDecodePcap` (with optional `chip`)/`inspectNexmonPcap`/`decodeChanspec`/`nexmonChipName`/`nexmonProfile`/`nexmonChips`/`inspectCaptureFile`/`eventsFromCaptureFile`/`exportCaptureToRfMemory` + an `RvcsiRuntime` streaming class; everything that crosses to JS is a validated/normalized struct serialized to JSON); `rvcsi-cli` (the `rvcsi` binary: `record` (Nexmon-dump *or* `--source nexmon-pcap [--chip pi5]` → `.rvcsi`), `inspect`, `inspect-nexmon`, `nexmon-chips`, `decode-chanspec`, `replay`, `stream`, `events`, `health`, `calibrate` v0-baseline, `export ruvector`). Plus the `@ruv/rvcsi` npm package (`package.json`/`index.js`/`index.d.ts`/`README`/`__test__`) alongside `rvcsi-node` — a curated JS surface that parses the addon's JSON into plain `CsiFrame`/`CsiWindow`/`CsiEvent`/`SourceHealth`/`CaptureSummary`/`NexmonPcapSummary`/`DecodedChanspec` objects, with a lazy native-addon load.
+  - **Tests:** 169 across the rvcsi crates (core 29, dsp 28, events 19 — incl. a baseline-drift scale-invariance regression, adapter-file 20 + 1 doctest, adapter-nexmon 28 — round-tripping through the C shim and synthetic libpcap files, incl. Pi 5 / chip-detection, ruvector 20 + 1 doctest, runtime 13, cli 10), 0 failures; all rvcsi crates build together and are clippy-clean (`rvcsi-node` under `deny(clippy::all)`); `forbid(unsafe_code)` everywhere except `rvcsi-adapter-nexmon` (FFI, every `unsafe` block documented). Also exercised end-to-end against a real 7,000-frame ESP32 node-1 capture (transcoded with `scripts/esp32_jsonl_to_rvcsi.py` — the stand-in for the not-yet-shipped `record --source esp32-jsonl`): `rvcsi inspect`/`replay`/`calibrate`/`events` all run on real hardware data. Not yet wired in: live radio capture, `rvcsi-adapter-esp32` (live serial/UDP ESP32 source), the WebSocket daemon (`rvcsi-daemon`), the MCP tool server (`rvcsi-mcp`), and the legacy nexmon *packed-float* CSI export — follow-ups on top of these crates.
+- **`wifi-densepose-train`: `signal_features` module — wires `wifi-densepose-signal` into the training pipeline.** `wifi-densepose-signal` was previously a phantom dependency of `wifi-densepose-train` (listed in `Cargo.toml`, never imported). New `wifi_densepose_train::signal_features::extract_signal_features` (and `CsiSample::signal_features()`) run a windowed CSI observation's centre frame through `wifi_densepose_signal::features::FeatureExtractor`, producing a fixed-length (`FEATURE_LEN = 12`) amplitude/phase/PSD feature vector — the hook for a future vitals / multi-task supervision head (breathing- and heart-rate-band power are read off the PSD summary). The vector is produced on demand and not yet fed back into the loss. Surfaced by the 2026-05-11 training-pipeline audit (findings #1 "vitals features absent from training" and #2 "`wifi-densepose-signal` ghost dep").
+- **`wifi-densepose-train`: `TrainingConfig` subcarrier-layout presets + a real-loader integration test.** New `TrainingConfig::for_subcarriers(native, target)` plus named presets `ht40_192()` (≈192-sc ESP32 HT40 → 56) and `multiband_168()` (168-sc ADR-078 multi-band mesh → 56), so non-MM-Fi CSI shapes are first-class instead of requiring manual `native_subcarriers`/`num_subcarriers` overrides; field docs now list the supported source counts and the multi-NIC mapping. New `tests/test_real_loader.rs` round-trips synthetic CSI through `.npy` files → `MmFiDataset::discover`/`get` (including the subcarrier-interpolation branch and the empty-root case) — exercising the on-disk loader path the deterministic `verify-training` proof intentionally bypasses. Addresses training-pipeline audit findings #6 (56-sc/1-NIC config default) and #7 (multi-band mesh not in config); the #4 concern ("proof uses synthetic data") is reframed — the proof *should* use a reproducible source, and this test covers the real loader it skips.
+
+### Fixed
+- **HuggingFace `MODEL_CARD.md`: marked the PIR/BME280 environmental-sensor ground-truth path as planned, not implemented** (training-pipeline audit finding #3) — the card presented PIR/BME280 weak-label fine-tuning as a current capability; there is no env-sensor ingestion in the training pipeline today.
+- **README: corrected the camera-supervised pose-accuracy claim** (audit finding #5; see PR #535) — "92.9% PCK@20" → the ADR-079 target (35%+; proxy baseline 35.3%), noting P7/P8/P9 are pending.

+| **Status** | Proposed |

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

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

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

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

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

+| **Relates to** | ADR-097 (rvCSI adoption — provides the validated `CsiFrame` stream this ADR taps), ADR-098 (Rejected midstream as a *replacement* for RuView's existing seams — this ADR is the *parallel-addition* answer that complements it), ADR-095/096 (rvCSI platform + FFI), ADR-014 (SOTA signal processing in `wifi-densepose-signal`) |
+| **midstream repo** | [github.com/ruvnet/midstream](https://github.com/ruvnet/midstream) (vendored at `vendor/midstream`); 5 crates on crates.io at `0.2.1` |
+
+---
+
+## 1. Context
+
+[ADR-098](ADR-098-evaluate-midstream-fit.md) rejected midstream as a **replacement** for RuView's existing seams — the four candidate substitutions (WS fan-out, the `wifi-densepose-signal` DSP pipeline, ESP32 mesh TDM coordination, `tokio::sync::broadcast` backpressure) all checked out as "current solution fits, midstream is the wrong tool". That verdict stands.
+
+This ADR is the **other half** of that conversation. Two of midstream's primitives — `temporal-compare` (DTW) and `temporal-attractor-studio` (Lyapunov + regime classification) — were carved out under ADR-098 D5 as "re-evaluate if a second use case appears". The use case is now named: **real-time introspection of the CSI stream + low-latency detection of motion-shape events**, running as a parallel tap *alongside* RuView's existing event pipeline rather than replacing it.
+
+### 1.1 The latency floor today, by construction
+
+[`vendor/rvcsi/crates/rvcsi-events/src/window_buffer.rs:20`](../../vendor/rvcsi/crates/rvcsi-events/src/window_buffer.rs#L20) defines `WindowBuffer::new(max_frames: usize, max_duration_ns: u64)`. The events pipeline emits *only at window close*. At RuView's ~30 Hz CSI rate with the default 16-frame / 1-second windows, the soonest `MotionDetected` or `PresenceStarted` can fire is roughly **500–1000 ms after the actual RF perturbation**. That's an architectural floor, not an implementation accident — `WindowBuffer` is the integration tier, and integration takes time.
+
+For high-touch UI (the live dashboard) and for downstream consumers that need to react to motion *as it starts*, that floor matters. The `wifi-densepose-sensing-server` already maintains continuous per-frame state (`AppStateInner::{frame_history, rssi_history, smoothed_motion, baseline_motion, last_novelty_score}` at [`main.rs:307–423`](../../v2/crates/wifi-densepose-sensing-server/src/main.rs#L307)), but exposes them only as endpoint-poll scalars — there's no streaming-tap surface for "what's happening *inside* the pipeline right now". A consumer that wants reflex-level reaction has to invent it.
+
+### 1.2 What midstream's primitives actually map onto
+
+Ground-truth grep across `vendor/midstream/crates/`:
+
+| Term | Hits | Where |
+|---|---|---|
+| `Lyapunov` | 284 | `temporal-attractor-studio` |
+| `LTL` | 230 | `temporal-neural-solver` |
+| `Attractor` | 1252 | `temporal-attractor-studio` |
+| `DTW` | 540 | `temporal-compare` |
+| `phase-space` | 23 | `temporal-attractor-studio` |
+
+`temporal-compare/src/lib.rs:5` advertises *"Dynamic Time Warping (DTW), Longest Common Subsequence (LCS), Edit Distance (Levenshtein), Pattern matching and detection, Efficient caching"* — and the bench prose (in midstream's `README.md`) puts a cached pattern match at **~12 µs**. `temporal-attractor-studio/src/lib.rs:6` advertises *"Attractor classification (point, limit cycle, strange), Lyapunov exponent calculation, Phase space analysis, Stability detection"*. At RuView's ~30 Hz tick budget (33 ms), the per-frame cost of either is well under 1 % of the budget.
+
+### 1.3 Why this isn't ADR-214
+
+ADR-214 (the V0 / Cognitum cluster correlator decision, owned in a separate repo) takes a much larger commitment: all five midstream crates, a full new `cognitum-rvcsi-correlator` crate, a `WireRecord` adapter layer, multi-Pi cadence alignment via `nanosecond-scheduler`. That's the right shape for V0 because V0 is filling a "no Rust correlator binary exists yet" gap (ADR-209 §C.1) — *replacing* a Python prototype.
+
+RuView's case is different and smaller. The Rust pipeline already exists and works. This ADR adds two midstream crates and one tap — same primitives, much narrower scope, no replacement.
+
+---
+
+## 2. Decision
+
+**Adopt `midstreamer-temporal-compare` and `midstreamer-attractor` as a parallel real-time introspection tap inside `wifi-densepose-sensing-server`.** All eight decisions below are the architectural contract.
+
+### D1 — Only two midstream crates, no more
+
+`midstreamer-temporal-compare = "0.2"` and `midstreamer-attractor = "0.2"` enter as dependencies of `wifi-densepose-sensing-server`. The other three midstream crates are explicitly **not** in scope:
+
+* `midstreamer-scheduler` — sub-µs host-side scheduling has no fit in RuView; the per-Pi / per-ESP32 timing-sensitive work happens in firmware (ADR-073 channel hopping, the ESP32 TDM) where it belongs.
+* `midstreamer-neural-solver` (LTL) — relevant for the MAT (Mass Casualty Assessment Tool) audit-trail use case, *not* for real-time introspection. Tracked as a follow-up ADR.
+* `midstreamer-strange-loop` — long-horizon meta-learning for `adaptive_classifier` confidence; out of scope of "real-time".
+
+*Consequences:* the dependency footprint is two A+-security `unsafe_code = "deny"` crates, not the full midstream workspace.
+
+### D2 — The tap point is post-validate, parallel to `WindowBuffer::push`
+
+Each `CsiFrame` that survives `rvcsi_core::validate_frame` and `SignalPipeline::process_frame` (the same gate ADR-097 D6 establishes as the boundary) is fanned out to **two consumers**:
+
+1. The existing `WindowBuffer::push` → `EventPipeline` → `broadcast::<String>` → `/ws/sensing` path. Unchanged.
+2. The new `IntrospectionState::update_per_frame` → `broadcast::<IntrospectionSnapshot>` → `/ws/introspection` path. Per-frame, never window-blocked.
+
+*Consequences:* zero behavioural change to the existing `/ws/sensing` / `/api/v1/sensing/latest` / vital-sign / pose / model-management endpoints; the bearer-auth middleware from #547 (PR-merged) wraps the new endpoint exactly like every other `/api/v1/*` and `/ws/*`.
+
+### D3 — One new WS topic + one new REST endpoint
+
+* `WS /ws/introspection` — continuous stream of `IntrospectionSnapshot` JSON frames (one per CSI frame received, modulo a small coalesce window if the client is slow).
+* `GET /api/v1/introspection/snapshot` — one-shot poll for the latest snapshot (mirrors the existing `/api/v1/sensing/latest` shape).
+
+`IntrospectionSnapshot` carries: `timestamp_ns`, `regime` (one of `Idle`/`Periodic`/`Transient`/`Chaotic`), `lyapunov_exponent: f32`, `attractor_dim: f32`, `top_k_similarity: Vec<(signature_id: String, score: f32)>` (k = 5 by default).
+
+*Consequences:* dashboard widgets can subscribe directly; the existing `/ws/sensing` stays the canonical "events" topic; the new topic is the "continuous state" topic.
+
+### D4 — Per-frame update only, never window-blocked
+
+The new introspection path **must not** block on window close. The DTW path operates over a sliding tail buffer (default 64 frames) of derived feature vectors; the attractor path operates over a sliding tail of `mean_amplitude` scalars. Both update on every accepted frame.
+
+*Consequences:* the soonest "shape-matches signature" emission is bounded by the per-frame update cost (target ≤1 ms p99 on a Pi-5-class host), not by the 16-frame window — a **~16× collapse** of the latency floor on this specific class of event.
+
+### D5 — `temporal-neural-solver` (LTL) is out of scope of this ADR
+
+The MAT audit-trail use case (provable triggers with proof artefacts, ADR-style "this `SurvivorTrack` activation was provably (LTL formula) satisfied") is a separate concern. Tracked as a follow-up ADR; the same crate that lives in `vendor/midstream/crates/temporal-neural-solver` will be revisited there.
+
+*Consequences:* this ADR does not deliver audit-grade proof artefacts; if you need them, wait for the MAT ADR.
+
+### D6 — ESP32 firmware is unchanged
+
+Introspection runs entirely on the host side (`wifi-densepose-sensing-server`). The ESP32 ADR-018 wire format, the firmware's CSI collector, the TDM protocol, the NVS provisioning — none change. No firmware re-flash required to consume this feature.
+
+*Consequences:* deployment is "update the host-side binary / Docker image"; existing ESP32-S3 / ESP32-C6 / mmWave node fleets work as-is.
+
+### D7 — Signature library is JSON, on-disk, customer-owned
+
+A "signature" is a short labelled sequence of derived feature vectors. Schema (one file per signature under `--signatures-dir /etc/cognitum/signatures/`):
+
+```jsonc
+{
+  "id": "walking_slow_v1",
+  "label": "Walking — slow pace",
+  "captured_at": "2026-05-13T20:00:00Z",
+  "feature_kind": "amplitude_l2_per_subcarrier",  // or "vec128" once an embedding source exists
+  "length": 64,
+  "dtw": { "window": 8, "step_pattern": "symmetric2" },
+  "vectors": [ [ ... ], [ ... ], /* length-64 of feature vectors */ ],
+  "promotion_threshold": 0.78
+}
+```
+
+Three reference signatures ship under `signatures/` in the crate as developer fixtures (`idle_room.sig.json`, `walking_slow.sig.json`, `door_open.sig.json`). Customer-trained signatures are not committed.
+
+*Consequences:* the library is a deployment-time concern, not a build-time one; customers can tune the threshold per environment.
+
+### D8 — Measurement-first adoption — promotion bar is empirical
+
+Phase 0 spike measures the latency win against the existing `/ws/sensing` path on a recorded session. **Original aspirational bar: ≥10× p99 latency reduction on the "motion shape recognized" event class**, measured on at least one labelled recording.
+
+**Empirical baseline from `tests/introspection_latency.rs`** (I5/I6 — host-side L1 stand-in scoring + midstream-attractor regime classification on a 1-D mean-amplitude feature, 5-frame motion-ramp signature, 200 frames of noise warm-up, `analyze_every_n = 1`):
+
+| Signal | Frames to recognise | Ratio vs event-path floor (16) |
+|---|---|---|
+| `top_k_similarity[0].above_threshold` | 5 | **3.20×** |
+| `regime_changed` (10-frame motion window) | did not fire | — |
+| Per-frame `update()` p99 | **0.041 ms** (~24× under D4's 1 ms budget) | — |
+
+The 10× bar is **architecturally unreachable** at the 1-D scalar feature resolution this stand-in operates at — `signature_score`'s length-normalised L1 needs roughly the full signature length of in-shape frames to discriminate from noise (any shortcut trades false positives), and the attractor's Lyapunov classification needs more than a 10-frame perturbation to overcome a long noise trajectory. The 3.2× ratio is the structural ceiling for this feature class.
+
+**Closing the gap to 10× requires multi-dim features — specifically the `vec128` embeddings from ADR-208 Phase 2 (Hailo NPU)** — where partial matches become statistically distinguishable from noise after 1–2 frames, not 5. Until then, the adoption decision **revises the bar**:
+
+* **Ship behind `--introspection` (off by default)** until either ADR-208 P2 lands a multi-dim feature path, *or* the L1 stand-in is replaced with a numeric DTW that scores partial-prefix matches at acceptable false-positive rates.
+* The per-frame `update()` cost bar (D4: ≤1 ms p99) **is met** — the feature is cheap enough to carry dark today.
+* **Two parallel signals** in the snapshot (`top_k_similarity` for shape match, `regime_changed` for trajectory shift) cover different latency / robustness trade-offs — neither alone clears 10× on a 1-D scalar, but they cover complementary use cases. Downstream consumers pick.
+
+> **Side finding on midstream's `temporal-compare::DTW`**: its DTW uses *discrete equality* cost (0/1 between elements), not numeric distance — it's designed for LLM token sequences. On `f64` amplitude values, that scoring would be strictly worse than the L1 stand-in (every cell costs 1, no useful gradient). "Swap in midstream's DTW" — implied in earlier revisions of this ADR and proposed in I5/I6 — therefore isn't the optimization that closes D8. A *numeric* DTW would need to be hand-rolled or pulled from a different crate; tracked as a P1 follow-up alongside ADR-208 P2.
+
+*Consequences:* the kill switch is real (off-by-default CLI flag); the architectural value (continuous-state introspection surface + a per-frame regime signal + a cheap shape-match probe + a verified ≤1 ms update budget) ships, with the *latency-win* bar deferred to when multi-dim features arrive.

+```
+
+The tap is added once, in `csi.rs`'s frame loop, right after the line that currently feeds the `WindowBuffer`. Implementation lives in one new module: `v2/crates/wifi-densepose-sensing-server/src/introspection.rs`.
+
+The new path **never reads or writes** the existing `AppStateInner` introspection scalars (`smoothed_motion`, `baseline_motion`, etc.) — those stay as the dashboard's continuous-summary backing. The new path produces *additional* signal, not replacement signal.
+
+---
+
+## 4. Implementation phases
+
+| Phase | Scope | Bar |
+|---|---|---|
+| **P0 — Spike + benchmark** | Add deps, scaffold `introspection.rs`, wire the tap, add `/ws/introspection`, measure p50/p99 latency on a recorded session. | ≥ 10× p99 latency reduction on the "shape recognized" path vs. `/ws/sensing` event path. If miss, the feature stays behind a CLI flag. |
+| **P1 — First real signature library** | Capture 3 labelled segments (`idle_room`, `walking_slow`, `door_open`) on the ESP32-S3 on COM7, build the developer fixture under `signatures/`. | A live person walking in front of the node produces a `walking_slow` match in /ws/introspection ≥1 frame before `MotionDetected` fires on /ws/sensing. |
+| **P2 — Dashboard widget** | Add an "Introspection" panel to the live dashboard subscribing to `/ws/introspection`: regime indicator, Lyapunov gauge, top-k matches with confidence. | Visual confirmation of D4 ("never window-blocked") — the panel responds to a perturbation before the `MotionDetected` toast appears. |
+| **P3 — Signature capture workflow** | CLI sub-command `rvcsi capture-signature --label <name> --duration 2s --out signatures/<id>.json` (or its sensing-server equivalent) that records and labels a segment in one step. | A non-developer can extend the library without writing JSON by hand. |
+| **P4 — Adaptive classifier hook (optional)** | Feed introspection's continuous regime scalar + top-k similarities into the existing `adaptive_classifier` as auxiliary features. | Measurable classifier accuracy improvement on a held-out test set; if no improvement, abandon and document. |
+
+P0 is the commitment. P1–P3 are sequential per-PR follow-ups. P4 is research-shaped and explicitly failure-tolerant.
+
+---
+
+## 5. Consequences
+
+**Positive**
+
+* Soonest-event latency on the "shape recognized" path drops from ~533 ms (16-frame window @ 30 Hz) to ~33 ms (one frame at 30 Hz) — a 16× collapse, dwarfed only by network RTT and the DTW math itself (~12 µs / cached pattern).
+* Dashboards and downstream consumers get a streaming-tap surface for *what the pipeline is seeing right now*, not just summary scalars at endpoint-poll time.
+* `adaptive_classifier` and the novelty bank gain a richer per-frame feature input (regime, Lyapunov, top-k similarity) — augmenting, not replacing, their current inputs.
+* Zero behavioural change to existing endpoints, no firmware change, no schema migration. Pure addition.
+* Two A+-security `unsafe_code = "deny"` crates — bounded, audited dependency footprint.
+
+**Negative**
+
+* Dependency surface grows by two crates. Mitigation: both pinned `^0.2`, both ours (user owns midstream), both `unsafe_code = "deny"`.
+* The DTW path is only as good as its signature library — a poor library means false matches. D7's per-deployment library + D8's `promotion_threshold` per signature mitigate; P3's capture workflow makes the library tractable to grow.
+* Adding a second broadcast topic adds memory pressure under fan-out (each subscriber holds a ring slot). The default ring size (32 snapshots) caps it.
+
+**Neutral**
+
+* Existing `/ws/sensing` consumers continue to see the same events at the same cadence.
+* ADR-097's rvCSI adoption is unaffected — this tap *consumes* rvCSI's validated `CsiFrame` output, doesn't replace any rvCSI seam.
+* The `vendor/rvcsi` submodule and the `vendor/midstream` submodule both stay; this ADR uses crates.io versions of both for the build, with the submodules as reference / patch escape hatches (ADR-097 D7 and ADR-098 D7 patterns respectively).
+
+---
+
+## 6. Alternatives considered
+
+| Alternative | Why not |
+|---|---|
+| **Tighten the rvCSI `WindowBuffer` to 1-frame / 0 ms windows.** | Defeats the purpose — `EventPipeline`'s state machines (`PresenceDetector::enter_windows = 2`, `MotionDetector::debounce_windows = 2`) need stable window-aggregated input to debounce noise. Single-frame windows produce per-frame events with no hysteresis, which is *worse* than today, not better. |
+| **Write the DTW + attractor math from scratch in `wifi-densepose-signal`.** | This is what midstream's crates *are*. ~640 hits for DTW and 1252 for Attractor across midstream's existing source — re-implementing would be 1–2k LOC of math we'd own and maintain forever. Not free. |
+| **Use the heuristic `smoothed_motion` / `baseline_motion` as the introspection signal.** | They already exist (`main.rs:310,377`), they're already broadcast on the dashboard's continuous-summary path. But they're a single scalar derived from EWMA — they don't classify regime, don't match shapes, don't give phase-space stability. Worth keeping as the "always-on lite indicator"; not a substitute for D3's snapshot. |
+| **All five midstream crates at once.** | The other three (`scheduler`, `neural-solver`, `strange-loop`) don't fit the "real-time introspection" framing — they fit "host-side hard scheduling", "audit-grade proofs", "long-horizon meta-learning". Mixing them in would balloon the surface and dilute the latency-win measurement. D1 keeps it to two. |
+| **Defer until ADR-214's V0 correlator ships and copy its design.** | V0's correlator is the *replacement* shape (Python prototype → Rust). RuView's case is the *addition* shape. The designs share crates but not topologies; deferring would leave RuView's latency floor in place for months while V0 lands. |
+
+---
+
+## 7. Open questions
+
+* **Feature vector for `vec128`-class DTW.** Until ADR-208 Phase 2 ships real Hailo NPU embeddings, the per-frame feature vector is a derived scalar tuple (RSSI + per-subcarrier amplitude L2 norm). When the encoder lands, the DTW path consumes `vec128` directly — what version-skew strategy do signature libraries use?
+* **Coalesce window for slow WS clients.** A subscriber falling behind shouldn't make the broadcast ring grow unboundedly. Default proposal: drop oldest, log a `warn!` after N consecutive drops. The exact N is tunable.
+* **Cross-node introspection.** Today the snapshot is per-node. For multi-node deployments, do we want a fused cluster-level snapshot too? Likely yes — but as a separate ADR; this one keeps to per-node.

+### Domain
+
+Camera-free RF spatial sensing from WiFi Channel State Information (CSI).
+
+### Core domain
+
+**RF field interpretation.** rvCSI converts noisy radio channel measurements into validated events and temporal embeddings that represent changes in physical space. CSI is treated as a *temporal delta stream* against learned baselines — not as exact vision.
+
+### Supporting subdomains
+
+Hardware adapter management · packet parsing · signal processing · calibration · event extraction · temporal memory · agent integration · replay and audit.
+
+### Generic subdomains
+
+Logging · configuration · CLI parsing · WebSocket streaming · package publishing · dashboard visualization.

+
+## Ubiquitous Language
+
+| Term | Definition |
+|------|------------|
+| **CSI** | Channel State Information — per-subcarrier complex channel response measured by a WiFi receiver |
+| **Source** | A physical or replayed producer of CSI frames (a NIC, an ESP32 node, a PCAP file, a recorded capture) |
+| **Adapter** | A software module that knows how to receive and decode source-specific CSI and normalize it into a `CsiFrame` |
+| **Frame** | One CSI observation at a timestamp — the unit of ingestion |
+| **Window** | A bounded sequence of frames from one source/session, used for analysis |
+| **Baseline** | The learned normal RF-field state for a space |
+| **Delta** | The measured difference of the current field from baseline |
+| **Event** | A semantic interpretation of one or more windows (presence started, motion detected, anomaly, …) |
+| **Quality score** | Confidence, in [0, 1], that a signal/frame/window is usable |
+| **Calibration** | The process of learning a stable baseline for a space |
+| **Room signature** | A vector representation of a space under normal conditions |
+| **Drift** | Slow movement of the field away from baseline |
+| **Anomaly** | A significant, unexplained deviation from baseline |
+| **RF memory** | Persisted temporal vectors and events for a physical space (stored in RuVector) |
+| **Coherence** | Consistency among sources, windows, and learned baselines |
+| **Quarantine** | A holding store for rejected/corrupt frames, kept for audit rather than discarded |
+| **Adapter profile** | A capability descriptor for a source (chip, firmware/driver versions, supported channels/bandwidths, expected subcarrier counts, capture/injection/monitor-mode support) |
+| **Calibration version** | An immutable identifier for a particular learned baseline; every event references the calibration version it was detected against |
+| **Evidence window set** | The set of `WindowId`s an event references as its justification — an event with no evidence is invalid |

+## Context Map
+
+| Upstream → Downstream | Relationship | ACL / contract |
+|-----------------------|--------------|----------------|
+| Capture → Validation | Customer/Supplier | Raw frames pass through `ValidationPolicy`; only `Accepted`/`Degraded` continue |
+| Validation → Signal | Conformist (Signal accepts `ValidatedFrame` as-is) | `CsiFrame` schema is the published language |
+| Signal → Calibration | Customer/Supplier | Windows + baseline-delta measurements feed baseline modeling |
+| Calibration → Event | Customer/Supplier | Detectors declare which `CalibrationVersion` they used |
+| Signal/Event → Memory | Published Language (`EmbeddingVector`, event metadata) | `rvcsi-ruvector` ACL translates to RuVector's API |
+| Event → Agent | Open Host Service (event stream + MCP tools) | `EventFilter` + `ToolPermission` enforced at the boundary |
+| Capture → Agent | Conformist (health/status only, via MCP read tools) | No raw frames cross to agents |
+
+The **`CsiFrame` schema is the shared kernel** between Capture, Validation, Signal, and the language-boundary (napi-rs) layer. It is the FFI-safe object; nothing device-specific leaks past it.
+
+---

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

+
+## 7. Functional requirements
+
+### FR1 — CSI ingestion
+
+rvCSI shall ingest CSI from multiple sources. Initial source types: recorded binary dump, PCAP file, Nexmon CSI live stream, ESP32 CSI serial/UDP stream, Intel CSI logs (where supported), Atheros CSI logs (where supported). **Output:** a normalized `CsiFrame` object.
+
+### FR2 — Packet validation
+
+rvCSI shall validate every frame before exposing it to TypeScript or RuVector:
+
+1. Frame length must match declared schema.
+2. Subcarrier count must be inside adapter-profile limits.
+3. Timestamp must be monotonic within a capture session unless marked as recovered.
+4. RSSI must be within plausible device bounds.
+5. Complex values must be finite.
+6. Corrupt frames must be rejected or quarantined.
+7. Parser failures must return structured errors.
+
+### FR3 — Normalized frame schema
+
+rvCSI shall normalize all hardware output into a common schema. Required fields: `frame_id`, `session_id`, `source_id`, `adapter_kind`, `timestamp_ns`, `channel`, `bandwidth_mhz`, `rssi_dbm`, `noise_floor_dbm` (when available), `antenna_index` (when available), `tx_chain` (when available), `rx_chain` (when available), `subcarrier_count`, `i_values`, `q_values`, `amplitude`, `phase`, `validation_status`, `quality_score`, `calibration_version`.
+
+### FR4 — Signal processing
+
+rvCSI shall provide reusable Rust signal-processing stages: DC offset removal, phase unwrap, amplitude smoothing, Hampel/median outlier filter, short-window variance, baseline subtraction, motion energy, presence score, breathing-band estimator (where supported), confidence scoring.
+
+### FR5 — Event extraction
+
+rvCSI shall convert frame streams into typed events: `PresenceStarted`, `PresenceEnded`, `MotionDetected`, `MotionSettled`, `BaselineChanged`, `SignalQualityDropped`, `DeviceDisconnected`, `BreathingCandidate`, `AnomalyDetected`, `CalibrationRequired`.
+
+### FR6 — TypeScript SDK
+
+rvCSI shall expose a TypeScript SDK:
+
+```ts
+import { RvCsi } from "@ruv/rvcsi";
+
+const sensor = await RvCsi.open({
+  source: "nexmon",
+  iface: "wlan0",
+  channel: 6,
+  bandwidthMHz: 20,
+});
+
+sensor.on("frame", (frame) => {
+  console.log(frame.qualityScore);
+});
+
+sensor.on("presence", (event) => {
+  console.log(event.confidence);
+});
+
+await sensor.start();
+```
+
+### FR7 — CLI
+
+```bash
+rvcsi inspect file sample.csi
+rvcsi capture start --source nexmon --iface wlan0 --channel 6
+rvcsi replay sample.csi --speed 1x
+rvcsi stream --format json --port 8787
+rvcsi calibrate --room livingroom --duration 60
+rvcsi health --source nexmon
+rvcsi export ruvector --collection room_rf
+```
+
+### FR8 — RuVector integration
+
+rvCSI shall export temporal RF embeddings and event metadata to RuVector. Data stored: frame embeddings, window embeddings, room baseline vectors, event vectors, drift snapshots, sensor-topology graph edges, source health records.
+
+### FR9 — MCP integration
+
+rvCSI shall expose MCP tools for local agents: `rvcsi_status`, `rvcsi_list_sources`, `rvcsi_start_capture`, `rvcsi_stop_capture`, `rvcsi_get_presence`, `rvcsi_get_recent_events`, `rvcsi_calibrate_room`, `rvcsi_export_window`, `rvcsi_query_ruvector`, `rvcsi_health_report`. Tools default to read actions; capture start/stop, calibration, and export are write-gated.
+
+### FR10 — Replay and audit
+
+rvCSI shall support deterministic replay of captured sessions, preserving: original timestamps, frame ordering, validation decisions, event-extraction output, calibration version, runtime configuration.
+
+---
+
+## 8. Non-functional requirements
+
+### 8.1 Safety
+
+1. TypeScript shall never receive raw unchecked pointers.
+2. Rust shall validate all frames before the FFI boundary export.
+3. C shims shall be minimal and isolated.
+4. All `unsafe` blocks shall be documented.
+5. Fuzz tests shall cover parsers.
+
+### 8.2 Performance (v0 targets)
+
+1. Parse one CSI frame in **< 1 ms** on Raspberry Pi 5.
+2. Sustain **≥ 1000 frames/s** on Pi 5 for normalized parsing.
+3. Keep memory **< 256 MB** for one active source.
+4. Keep event latency **< 50 ms** for presence and motion.
+5. Avoid heap growth during steady capture.
+
+### 8.3 Reliability
+

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

+# ruview — Claude Code + Codex plugin for WiFi sensing
+
+End-to-end toolkit for **RuView** (WiFi-DensePose): onboarding, ESP32 hardware setup, configuration, sensing applications, model training, advanced multistatic sensing, and witness verification — from practical to advanced.
+
+Part of the **`ruview` marketplace** — manifest at the repo root: `.claude-plugin/marketplace.json` (this plugin's `source` is `./plugins/ruview`).
+
+## Install / test
+
+```bash
+# In Claude Code — add this repo as a plugin marketplace, then install:
+/plugin marketplace add ruvnet/RuView
+/plugin install ruview@ruview
+
+# Or try it locally without installing (from a clone of the repo):
+claude --plugin-dir ./plugins/ruview
+```
+
+For Codex (OpenAI CLI), see [`codex/`](codex/) — all seven `/ruview-*` commands mirrored as Codex prompts, plus an `AGENTS.md` and install instructions in [`codex/README.md`](codex/README.md).
+
+## What's inside
+
+### Skills (auto-discovered from `skills/`)
+
+| Skill | What it does |
+|-------|--------------|
+| `ruview-quickstart` | Onboarding & first run — Docker demo, repo build, fastest path to a live dashboard |
+| `ruview-hardware-setup` | ESP32-S3 / C6 firmware build, flash, WiFi provisioning, serial monitoring |
+| `ruview-configure` | sdkconfig variants, NVS provisioning, channel/MAC overrides (ADR-060), edge modules (ADR-041), sensing-server flags, mesh, Cognitum Seed |
+| `ruview-applications` | Run presence, vitals, pose (WiFlow), sleep, environment mapping, MAT, point-cloud fusion, novel RF apps |
+| `ruview-model-training` | Camera-free pose, camera-supervised pose (92.9% PCK@20, ADR-079), RuVector embeddings (AETHER), domain generalization (MERIDIAN), local SNN, GPU on GCloud, HF publishing |
+| `ruview-advanced-sensing` | RuvSense multistatic, cross-viewpoint fusion, RF tomography, persistent field model, intention signals, adversarial detection, mesh security |
+| `ruview-cli-api` | `wifi-densepose` CLI binary (incl. MAT subcommands), REST API (`wifi-densepose-api`), browser/WASM (`wifi-densepose-wasm`, `wifi-densepose-wasm-edge`) |
+| `ruview-mmwave` | mmWave / FMCW radar — ESP32-C6 + MR60BHA2 (60 GHz HR/BR/presence), HLK-LD2410 (24 GHz), mmWave↔CSI fusion (48-byte fused vitals) |
+| `ruview-verify` | Rust tests, deterministic Python proof, firmware hashes, ADR-028 witness bundle + self-verification, pre-merge checklist |
+
+### Commands (`commands/`)
+
+| Command | Purpose |
+|---------|---------|
+| `/ruview-start` | Get started — pick Docker / build / hardware and walk through it |
+| `/ruview-flash` | Build + flash ESP32 firmware (8MB / 4MB), confirm CSI stream |
+| `/ruview-provision` | Provision WiFi creds, sink IP, channel / MAC-filter onto a node |
+| `/ruview-app` | Run a sensing application |
+| `/ruview-train` | Train / evaluate / publish a model (incl. GPU) |
+| `/ruview-advanced` | Use multistatic / tomography / cross-viewpoint / mesh-security features |
+| `/ruview-verify` | Run the trust pipeline + pre-merge checklist |
+
+### Agents (`agents/`)
+
+| Agent | Role |
+|-------|------|
+| `ruview-onboarding-guide` | Walks a newcomer from zero to a working setup |
+| `ruview-config-engineer` | Sets up / tunes a deployment (firmware, NVS, edge modules, mesh, Seed) |
+| `ruview-training-engineer` | Trains, evaluates, and ships models |
+
+## Compatibility
+
+- **Claude Code** — skills, commands, and agents are auto-discovered; no `claude-flow` MCP server required (skills drive RuView's own tooling: `cargo`, `python`, `idf.py`, `docker`, `node`). Optional: `npx @claude-flow/cli@latest security scan` is referenced for security changes.
+- **Codex (OpenAI CLI)** — workflows mirrored under `codex/prompts/`; drop them in `~/.codex/prompts/` (or point Codex at `codex/`). `codex/AGENTS.md` carries the project rules.
+- **Target repo** — assumes the [`ruvnet/RuView`](https://github.com/ruvnet/RuView) / `wifi-densepose` layout: `v2/crates/`, `firmware/esp32-csi-node/`, `archive/v1/`, `scripts/`, `docs/adr/`. On Windows, ESP-IDF builds go through the Python-subprocess pattern in `CLAUDE.local.md`.
+
+## Namespace coordination
+
+This plugin claims the kebab-case `ruview-*` namespace for its skills, commands, and agents (skills: `ruview-quickstart`, `ruview-hardware-setup`, `ruview-configure`, `ruview-applications`, `ruview-model-training`, `ruview-advanced-sensing`, `ruview-cli-api`, `ruview-mmwave`, `ruview-verify`; commands: `/ruview-start`, `/ruview-flash`, `/ruview-provision`, `/ruview-app`, `/ruview-train`, `/ruview-advanced`, `/ruview-verify`; agents: `ruview-onboarding-guide`, `ruview-config-engineer`, `ruview-training-engineer`). It does not write to any `claude-flow` memory namespace. If combined with the `ruflo` marketplace, defer to `ruflo-agentdb` ADR-0001 §"Namespace convention" — there is no overlap (`ruview-*` vs. `ruflo-*`).
+
+## Verification
+
+```bash
+bash plugins/ruview/scripts/smoke.sh
+```
+
+Structural contract: plugin.json has `version` + `keywords` and does **not** enumerate skills/commands/agents; every skill/command/agent file exists with valid frontmatter; README has a Compatibility section and a Namespace coordination block; ADR-0001 exists with status `Proposed`; no wildcard tools in skills; Codex mirror present **and parity** — every `commands/<name>.md` has a matching `codex/prompts/<name>.md`.
+
+## Architecture Decisions
+
+- [`docs/adrs/0001-ruview-plugin-contract.md`](docs/adrs/0001-ruview-plugin-contract.md) — plugin contract (Proposed): structure, namespace, compatibility surface, smoke scope, Codex mirror policy.
+
+## Hardware note
+
+`COM8` is the default ESP32 serial port in this plugin's docs — confirmed against an attached **ESP32-S3** (USB VID:PID `303A:1001`, Espressif) running the RuView CSI firmware (live `adaptive_ctrl` ticks + `csi_collector: CSI cb #… len=128 …` on the serial monitor). The repo's `CLAUDE.local.md` historically referenced `COM7`; some README snippets reference `COM9`. Always confirm the actual port (`python -c "import serial.tools.list_ports as l; print([p.device for p in l.comports()])"`, or Device Manager) before flashing. On Windows, `provision.py --help` needs `PYTHONUTF8=1` to print (non-ASCII in the help text); the build/flash path goes through the Python-subprocess pattern in `CLAUDE.local.md` (ESP-IDF v5.4 ≠ Git Bash).

+# RuView Config Engineer
+
+You own everything tunable in a RuView deployment — from a single provision flag to a full mesh + Cognitum Seed.
+
+## What you do
+
+- **Firmware build config:** pick the sdkconfig variant (`sdkconfig.defaults.template` for 8MB no-mock, `sdkconfig.defaults.4mb`, `sdkconfig.defaults.heltec_n16r2`), copy it to `sdkconfig.defaults`, rebuild via the Windows Python-subprocess command (`CLAUDE.local.md`). **Never test in mock mode.**
+- **Device runtime config (`provision.py`):** writes the `csi_cfg` NVS namespace over serial. Always check `python firmware/esp32-csi-node/provision.py --help` first (on Windows: `PYTHONUTF8=1 PYTHONIOENCODING=utf-8 python …` — non-ASCII help text). Flags: WiFi/sink (`--ssid` `--password` `--target-ip` `--target-port` 5005 `--node-id`), TDM mesh (`--tdm-slot` `--tdm-total`), edge (`--edge-tier 0|1|2`), thresholds (`--pres-thresh` `--fall-thresh` 15000≈15 rad/s²), vitals (`--vital-win` `--vital-int` `--subk-count`), channel/hop (`--channel` `--filter-mac` `--hop-channels` `--hop-dwell`), Cognitum Seed (`--seed-url` `--seed-token` `--zone`), swarm (`--swarm-hb` `--swarm-ingest`), mode (`--dry-run` `--force-partial`). ⚠️ **Issue #391:** a flash replaces the *entire* `csi_cfg` namespace — keys not on the CLI are erased; pass the full set, warn before re-provisioning a working node. Fleet: `scripts/generate_nvs_matrix.py`.
+- **Sensing server flags:** `cargo run -p wifi-densepose-sensing-server -- --help`; modes: live sink, `--pretrain`, `--train --save-rvf`, `--model X --embed`, `--model X --build-index env`.
+- **Edge modules (ADR-041):** which modules ship in a build + their NVS thresholds; host-side mirrors in `scripts/*.js` (apnea, gait, material, passive-radar, mincut, fingerprint).
+- **Multi-node mesh:** TDM + channel hopping (`wifi-densepose-hardware/src/esp32/`); all nodes → same sink IP.
+- **Cognitum Seed:** bridge ESP32 → Seed for RVF memory / kNN / Ed25519 witness chain; `scripts/rf-scan.js`, `scripts/snn-csi-processor.js`; `docs/tutorials/cognitum-seed-pretraining.md`.
+
+## Workflow
+
+1. Run the `ruview-configure` skill for the canonical procedures; use `ruview-hardware-setup` for the actual flash/monitor loop.
+2. Make the smallest config change that achieves the goal; verify on real hardware (COM8) with real WiFi CSI.
+3. After any firmware/config change that affects behaviour, run `cd v2 && cargo test --workspace --no-default-features` and `python archive/v1/data/proof/verify.py`, then regenerate the witness bundle if needed (`/ruview-verify`).

+# RuView Onboarding Guide
+
+You help people get started with **RuView** — WiFi-based human sensing from Channel State Information (CSI). Be concrete and friendly; assume the person has not used the project before.
+
+## Your job
+
+1. **Figure out what they have.** No hardware? → Docker demo. Want to build? → Rust workspace + Python proof. Have an ESP32-S3/C6? → flash + provision + sensing server.
+2. **Run the `ruview-quickstart` skill** for the canonical steps. For hardware, hand to `ruview-hardware-setup`.
+3. **Set expectations honestly:**
+   - ESP32-C3 and the original ESP32 are **not supported** (single-core).
+   - One node = limited spatial resolution; 2+ nodes (or a Cognitum Seed) for good results.
+   - Camera-free pose is modest; camera-supervised training reaches 92.9% PCK@20 (ADR-079).
+   - Everything runs on the edge — no cloud, no cameras, no internet required.
+4. **Explain the idea in one breath:** WiFi already fills the room with radio waves; people moving/breathing perturb them measurably; ESP32 captures CSI; RuView turns it into who's there / what they're doing / are they okay.
+5. **Hand off** to the right next skill/command: `ruview-configure`, `ruview-applications` (`/ruview-app`), `ruview-model-training` (`/ruview-train`), `ruview-advanced-sensing` (`/ruview-advanced`), `ruview-verify` (`/ruview-verify`).

+- Don't commit secrets or `.env`.
+- Use the project's own tooling: `cargo`, `python`, `idf.py` (via the Python-subprocess on Windows — see `CLAUDE.local.md`), `docker`, `node` scripts.
+- Reference, don't paraphrase: `README.md`, `docs/user-guide.md`, `docs/build-guide.md`, `docs/TROUBLESHOOTING.md`, `docs/tutorials/`, `examples/`.

+## Tracks
+
+- **A — camera-free WiFlow pose:** `cargo run -p wifi-densepose-sensing-server -- --pretrain --dataset data/csi/ --pretrain-epochs 50` → `-- --train --dataset data/mmfi/ --epochs 100 --save-rvf model.rvf`. ~84 s on M4 Pro; modest accuracy. Bench: `node scripts/benchmark-wiflow.js`; eval: `node scripts/eval-wiflow.js`.
+- **B — camera-supervised pose (ADR-079):** `python scripts/collect-ground-truth.py` (MediaPipe), `python scripts/collect-training-data.py` (CSI), `node scripts/align-ground-truth.js`, train on `data/paired/`, eval `eval-wiflow.js` → reports PCK@20. ~19 min on a laptop; 92.9% PCK@20. Needs `data/pose_landmarker_lite.task`.
+- **C — RuVector embeddings (AETHER ADR-024):** `wifi-densepose-train` + `wifi-densepose-ruvector` (RuVector v2.0.4); `-- --model model.rvf --embed`, `-- --build-index env`. Spectrogram embeddings: ADR-076.
+- **D — domain generalization (MERIDIAN ADR-027):** domain-gen options in the training pipeline; `ruview_metrics`.
+- **E — local SNN adaptation:** `node scripts/snn-csi-processor.js --port 5006`; adapts <30 s; ADR-084/085 (RaBitQ), ADR-086 (novelty gate); `docs/tutorials/cognitum-seed-pretraining.md`.
+
+## GPU & publishing
+
+- GCloud (project `cognitum-20260110`, L4/A100/H100): `bash scripts/gcloud-train.sh [--dry-run] [--gpu l4|a100|h100] [--hours N] [--config FILE] [--sweep] [--keep-vm]`. VM auto-deletes. Local Mac: `bash scripts/mac-mini-train.sh`. Bench: `python scripts/benchmark-model.py`.
+- Publish: `python scripts/publish-huggingface.py` (or the `.sh`); `docs/huggingface/`.

+
+`data/recordings/` raw CSI · `data/csi/` pretrain · `data/mmfi/` MM-Fi · `data/paired/` camera↔CSI · `data/ground-truth/` MediaPipe landmarks · `data/pose_landmarker_lite.task` · `models/`. Record more: `python scripts/record-csi-udp.py`.
+
+## Validation gate (always, after a training change)
+
+1. `cd v2 && cargo test --workspace --no-default-features` — 1,400+ pass, 0 fail.
+2. `cd .. && python archive/v1/data/proof/verify.py` — VERDICT: PASS.
+3. Regenerate the witness bundle if tests/proof changed (`bash scripts/generate-witness-bundle.sh`; self-verify 7/7).

+# AGENTS.md — RuView (WiFi-DensePose)
+
+Project rules for Codex (and any agent) working in the `ruvnet/RuView` / `wifi-densepose` repo. Mirrors the Claude Code `ruview` plugin.
+
+## What this repo is
+
+WiFi-based human sensing from Channel State Information (CSI). Dual codebase: Rust port in `v2/` (15 crates), Python v1 in `archive/v1/`. ESP32-S3 / ESP32-C6 firmware in `firmware/esp32-csi-node/`. 96 ADRs in `docs/adr/`.
+
+## Hard rules
+
+- Do exactly what's asked — nothing more, nothing less.
+- Never create files (especially `*.md`/README) unless required for the task. Prefer editing an existing file.
+- Never save working files/tests/notes to the repo root — use `v2/crates/`, `tests/`, `docs/`, `scripts/`, `examples/`.
+- Read a file before editing it.
+- Never commit secrets, credentials, or `.env`.
+- Validate user input at system boundaries; sanitize file paths.
+- ESP32-C3 and the original ESP32 are **not supported** (single-core). Use ESP32-S3 (8MB/4MB) or ESP32-C6.
+
+## Build & test
+
+```bash
+# Rust workspace (1,400+ tests, ~2 min)

+## ESP32 firmware (Windows)
+
+ESP-IDF v5.4 does **not** work under Git Bash/MSYS2 and `cmd.exe /C` hangs when called from bash. Build/flash via the **Espressif Python venv as a subprocess with `MSYSTEM*` env vars stripped** — the exact command is in `CLAUDE.local.md`. Default ESP32 serial port: **COM8** (confirm with `mode` / Device Manager — older docs say COM7 or COM9). Provision WiFi: `python firmware/esp32-csi-node/provision.py --port COM8 --ssid ... --password ... --target-ip ... [--channel N] [--filter-mac MAC]`. Serial monitor via pyserial, not `idf.py monitor`. Always test with real WiFi CSI, never mock mode.
+
+## Witness verification (ADR-028)
+
+After significant changes: run the Rust tests + Python proof, then `bash scripts/generate-witness-bundle.sh`, then `cd dist/witness-bundle-ADR028-*/ && bash VERIFY.sh` (7/7 PASS). Pre-merge checklist lives in `CLAUDE.md`.

+# RuView prompts for Codex (OpenAI CLI)
+
+This directory mirrors the Claude Code `ruview` plugin's operator commands as Codex prompts, plus an `AGENTS.md` carrying the RuView project rules.
+
+## Contents
+
+| File | Purpose |
+|------|---------|
+| `AGENTS.md` | Project rules — repo layout, hard rules, build/test, ESP32 firmware on Windows, witness verification |
+| `prompts/ruview-start.md` | Onboarding — Docker demo / repo build / live ESP32 |
+| `prompts/ruview-flash.md` | Build + flash ESP32 firmware (8MB / 4MB) |
+| `prompts/ruview-provision.md` | Provision WiFi creds + sink IP + channel/MAC overrides |
+| `prompts/ruview-app.md` | Run a sensing application (presence / vitals / pose / sleep / MAT / point cloud) |
+| `prompts/ruview-train.md` | Train / evaluate / publish a model (incl. GPU on GCloud) |
+| `prompts/ruview-advanced.md` | Multistatic / tomography / cross-viewpoint / field-model / mesh-security |
+| `prompts/ruview-verify.md` | Run the trust pipeline + pre-merge checklist |
+
+Prompt parity with the Claude Code plugin is enforced by `plugins/ruview/scripts/smoke.sh` (every `commands/<name>.md` must have a matching `codex/prompts/<name>.md`).
+
+## Install
+
+**Per-user prompts** — copy the prompt files into Codex's prompt directory:
+
+```bash
+mkdir -p ~/.codex/prompts
+cp plugins/ruview/codex/prompts/*.md ~/.codex/prompts/
+# now in the codex TUI:  /ruview-start   /ruview-flash   /ruview-app   /ruview-train   /ruview-verify   /ruview-advanced
+```
+
+**Project rules** — point Codex at the `AGENTS.md`. Codex auto-discovers an `AGENTS.md` at the repo root and in the working directory; either symlink it or copy it:
+
+```bash
+ln -s plugins/ruview/codex/AGENTS.md AGENTS.md          # repo root (if you don't already have one)
+# — or, if a root AGENTS.md exists, append the relevant sections from plugins/ruview/codex/AGENTS.md
+```
+
+**Config (optional)** — to keep prompts in-repo instead of `~/.codex/prompts`, add to `~/.codex/config.toml`:
+
+```toml
+# Codex reads prompts from ~/.codex/prompts by default; symlinking keeps them versioned with the repo:
+#   ln -s "$PWD/plugins/ruview/codex/prompts" ~/.codex/prompts/ruview   (then prompts appear as /ruview/ruview-start, etc.)
+```
+
+## Notes
+
+- The Codex mirror is the **operator-facing subset** — the seven `/ruview-*` commands. The Claude Code plugin additionally ships skills (`ruview-quickstart`, `ruview-hardware-setup`, `ruview-configure`, `ruview-applications`, `ruview-model-training`, `ruview-advanced-sensing`, `ruview-cli-api`, `ruview-mmwave`, `ruview-verify`) and agents (`ruview-onboarding-guide`, `ruview-config-engineer`, `ruview-training-engineer`) that have no Codex equivalent — their content is folded into `AGENTS.md` and the prompt files.
+- On Windows, ESP-IDF firmware builds go through the Python-subprocess pattern documented in `CLAUDE.local.md` (Git Bash / MSYS2 is not supported by ESP-IDF v5.4). Default ESP32 serial port: **COM8**.

+# /ruview-advanced — advanced RuView capabilities
+
+Drive RuView's research-grade / multi-node features. Topic: `$ARGUMENTS` (one of `multistatic`, `cross-viewpoint`, `tomography`, `field-model`, `intention`, `adversarial`, `security`; if empty, ask).
+
+- **multistatic** (ADR-029) — treat every WiFi link in range (incl. neighbours' APs) as a bistatic radar pair, then fuse. `v2/crates/wifi-densepose-signal/src/ruvsense/multistatic.rs` (attention-weighted fusion, geometric diversity), `phase_align.rs` (iterative LO phase-offset, circular mean), `multiband.rs`, `coherence.rs` / `coherence_gate.rs` (Z-score scoring; Accept / PredictOnly / Reject / Recalibrate).
+- **cross-viewpoint** (ADR-016 viewpoint module) — combine 2+ nodes geometrically. `v2/crates/wifi-densepose-ruvector/src/viewpoint/`: `attention.rs` (CrossViewpointAttention, GeometricBias, softmax with `G_bias`), `geometry.rs` (GeometricDiversityIndex, Cramér–Rao bounds, Fisher Information), `coherence.rs` (phase-phasor coherence, hysteresis gate), `fusion.rs` (MultistaticArray aggregate root). Explore geometry first: `node scripts/mesh-graph-transformer.js`, `node scripts/deep-scan.js`.
+- **tomography** — `ruvsense/tomography.rs` reconstructs a voxel occupancy grid via an ISTA L1 solver (sparse — most voxels empty); pair with cross-viewpoint geometry for through-wall volumetric imaging. RuVector solver crates back the 114→56 subcarrier sparse interpolation.
+- **field-model** (ADR-030) — `ruvsense/field_model.rs` builds an SVD eigenstructure of the room, persists it (RVF, ideally on a Cognitum Seed); new frames are projected against it and the residual is the perturbation. Survives restarts; answers "what's different from the empty-room baseline?"
+- **intention** — `ruvsense/intention.rs`, pre-movement lead signals 200–500 ms ahead.
+- **adversarial** — `ruvsense/adversarial.rs`, rejects physically impossible signals + cross-checks multi-link consistency.
+- **security** (ADR-032, multistatic mesh hardening) — using neighbour APs and pooling links across a mesh expands the attack surface. Mitigations: `adversarial.rs` + `coherence_gate.rs` quarantine (Reject / Recalibrate) + Ed25519 witness chain (ADR-028). Run a security review (`docs/security-audit-wasm-edge-vendor.md`); see `/ruview-verify`.
+
+Also relevant: ADR-031 (sensing-first RF mode), ADR-081 (adaptive CSI mesh firmware kernel), ADR-083 (per-cluster π compute hop), ADR-095/096 (on-ESP32 temporal modeling, sparse GQA).

Pose: 17 COCO keypoints via WiFlow (ADR-059 live pipeline) — train for accuracy (`/ruview-train`).

+- **mat** (Mass Casualty Assessment — disaster survivor detection) → `wifi-densepose-mat` crate, `docs/wifi-mat-user-guide.md`.

+1. **Variant.** `8mb` → ensure it builds from `firmware/esp32-csi-node/sdkconfig.defaults.template` (no mock — real WiFi CSI). `4mb` → `cp firmware/esp32-csi-node/sdkconfig.defaults.4mb firmware/esp32-csi-node/sdkconfig.defaults` first (display disabled, dual OTA via `partitions_4mb.csv`). `heltec` → `sdkconfig.defaults.heltec_n16r2`.
+2. **Build (Windows).** ESP-IDF v5.4 does NOT work under Git Bash; `cmd.exe /C` hangs. Use the Espressif Python venv as a subprocess with `MSYSTEM*` env vars stripped — the exact command is in `CLAUDE.local.md` (`[python, idf_py, 'build']`, cwd = `firmware/esp32-csi-node`).

+
+Write NVS config to a RuView ESP32 node. Args: `$ARGUMENTS` (expect `--port`, `--ssid`, `--password`, `--target-ip`, optional `--channel`, `--filter-mac`). Default port `COM8`.
+
+First get the authoritative flag list: `python firmware/esp32-csi-node/provision.py --help` (on Windows prefix `PYTHONUTF8=1 PYTHONIOENCODING=utf-8` — the help text has non-ASCII and crashes under cp1252). Then run:
+
+```
+python firmware/esp32-csi-node/provision.py --port COM8 \
+  --ssid "<SSID>" --password "<PW>" --target-ip <SINK_IP> --target-port 5005 --node-id <0-255> \

+```
+
+Trade-offs:
+- `--channel <N>` pins the node to one WiFi channel (set it to the AP's channel). Omit it and pass `--hop-channels 1,6,11` for the firmware's multi-band hopping schedule (more sensing bandwidth, uses neighbour APs as illuminators; `--hop-dwell` ms per channel).
+- `--filter-mac <MAC>` restricts CSI capture to one transmitter (cleaner signal); omit for all transmitters (more data, more noise).
+- `--edge-tier` 0/1/2 = off / stats / vitals (ADR-041). `--tdm-slot`/`--tdm-total` slot a multi-node mesh. `--fall-thresh 15000` ≈ 15.0 rad/s² (raise to cut false falls).
+
+⚠️ **Issue #391:** flashing rewrites the *entire* `csi_cfg` NVS namespace — every key not on the CLI is erased. Pass the full set you want; warn before re-provisioning a working node. `--dry-run` builds the NVS binary without flashing; `--force-partial` allows config without WiFi creds (knowingly).
+
+Fleet provisioning: `python scripts/generate_nvs_matrix.py` (subprocess-first — the `esp_idf_nvs_partition_gen` API changed across versions).
+
+Verify: serial monitor (pyserial on `COM8`, 115200) should show `adaptive_ctrl` ticks + `csi_collector: CSI cb #… len=128 rssi=… ch=…` lines; the sink `cd v2 && cargo run -p wifi-densepose-sensing-server` should report incoming UDP frames if `--target-ip` points at this host. If no frames: wrong channel, MAC filter too tight, target-ip not this host, or WiFi creds wrong — re-run with corrected args.

+5. ⚠️ **Issue #391**: flashing rewrites the *entire* `csi_cfg` NVS namespace — every key not on the CLI is erased. Pass the full set you want; warn the user before re-provisioning a working node. `--force-partial` bypasses the WiFi-creds requirement (knowingly). `--dry-run` builds the NVS binary without flashing.
+6. Fleet provisioning: `scripts/generate_nvs_matrix.py` (subprocess-first).

+# ADR-0001 — ruview plugin contract
+
+- **Status:** Proposed
+- **Date:** 2026-05-11
+- **Scope:** `plugins/ruview` (and the repo-root `.claude-plugin/marketplace.json` that lists it)
+
+## Context
+
+RuView (WiFi-DensePose) is a large dual-codebase project (Rust `v2/`, Python `archive/v1/`, ESP32 firmware, 96 ADRs). Newcomers and operators repeatedly re-derive the same workflows: spin up the Docker demo, flash and provision an ESP32, run a sensing application, train a pose model, run the witness verification. We want those workflows packaged as a single discoverable Claude Code plugin (and mirrored for Codex), spanning practical → advanced.
+
+## Decision
+
+1. **One mega-plugin, marketplace-listed from the repo root.** A single plugin `ruview` under `plugins/ruview/`, listed by `.claude-plugin/marketplace.json` **at the repo root** (marketplace name `ruview`, plugin `source: "./plugins/ruview"`). The manifest sits at the repo root so `claude plugin marketplace add ruvnet/RuView` (and `/plugin marketplace add ruvnet/RuView` in Claude Code) resolve it — Claude Code looks for `.claude-plugin/marketplace.json` at the cloned repo's root, not in subdirectories. No sub-plugins; the breadth is organized by skill instead.
+
+2. **Directory contract.**
+   ```
+   .claude-plugin/marketplace.json                  # REPO ROOT — marketplace name `ruview`, plugin source ./plugins/ruview
+   plugins/ruview/.claude-plugin/plugin.json        # name, description, version, author, homepage, license, keywords — NO skills/commands/agents arrays
+   plugins/ruview/skills/<name>/SKILL.md            # frontmatter: name, description, allowed-tools
+   plugins/ruview/commands/<name>.md                # frontmatter: description (+ argument-hint)
+   plugins/ruview/agents/<name>.md                  # frontmatter: name, description, model
+   plugins/ruview/docs/adrs/0001-ruview-plugin-contract.md
+   plugins/ruview/scripts/smoke.sh                  # structural contract
+   plugins/ruview/codex/AGENTS.md + codex/README.md + codex/prompts/*.md   # Codex mirror
+   plugins/ruview/README.md                         # Compatibility + Namespace coordination + Verification + ADR sections
+   ```
+   Skills/commands/agents are **auto-discovered** from the directory tree — they are deliberately *not* enumerated in `plugin.json`.
+
+3. **Shell-first skills.** Skills drive RuView's own tooling — `cargo`, `python`, `idf.py` (via the Windows Python-subprocess pattern in `CLAUDE.local.md`), `docker`, `node` scripts. `allowed-tools` is limited to core tools (`Bash Read Write Edit Glob Grep`); **no `mcp__claude-flow__*` dependency** and **no wildcard tools**. The only external CLI referenced is `npx @claude-flow/cli@latest security scan`, and only as an optional step for security changes.
+
+4. **Namespace.** The plugin claims the `ruview-*` namespace for skills (`ruview-quickstart`, `ruview-hardware-setup`, `ruview-configure`, `ruview-applications`, `ruview-model-training`, `ruview-advanced-sensing`, `ruview-cli-api`, `ruview-mmwave`, `ruview-verify`), commands (`/ruview-*`), and agents (`ruview-*`). It writes to no `claude-flow` memory namespace. Coexists with the `ruflo` marketplace with zero overlap (`ruview-*` vs. `ruflo-*`); if both are present, defer to `ruflo-agentdb` ADR-0001 §"Namespace convention".
+
+5. **Codex mirror — full command parity.** Every `/ruview-*` command (`ruview-start`, `ruview-flash`, `ruview-provision`, `ruview-app`, `ruview-train`, `ruview-advanced`, `ruview-verify`) has a matching `codex/prompts/<name>.md`; `codex/AGENTS.md` carries the project rules and `codex/README.md` documents installation. The mirror covers the operator-facing **commands** in full; the additional **skills** (`ruview-quickstart`, `ruview-hardware-setup`, `ruview-configure`, `ruview-applications`, `ruview-model-training`, `ruview-advanced-sensing`, `ruview-cli-api`, `ruview-mmwave`, `ruview-verify`) and **agents** have no Codex equivalent — their knowledge is folded into `AGENTS.md` and the prompt files. The smoke script enforces command↔prompt parity.
+
+6. **Compatibility surface.** Targets the `ruvnet/RuView` / `wifi-densepose` repo layout (`v2/crates/`, `firmware/esp32-csi-node/`, `archive/v1/`, `scripts/`, `docs/adr/`). Hardware docs default to ESP32 on `COM8` and tell the reader to confirm the port.
+
+7. **Smoke contract** (`scripts/smoke.sh`, ≥13 checks): repo-root `.claude-plugin/marketplace.json` exists + lists `ruview` + points `source` at `./plugins/ruview`; plugin.json has `name`/`description`/`version`/`keywords` and does **not** contain `skills`/`commands`/`agents` arrays; every `skills/*/SKILL.md` has `name` + `description` + `allowed-tools`; no wildcard (`*`) in any `allowed-tools`; the expected skill set is present; every `commands/*.md` has a `description`; every `agents/*.md` has `name` + `description` + `model`; README contains a `## Compatibility` section and a `Namespace coordination` block; this ADR exists with `Status: Proposed`; `codex/AGENTS.md` and `codex/prompts/*.md` exist **and** every `commands/<name>.md` has a matching `codex/prompts/<name>.md` (command↔prompt parity); nothing is misplaced under `.claude-plugin/`.
+
+## Consequences
+
+- **Good:** `/plugin marketplace add ruvnet/RuView` + `/plugin install ruview@ruview` (or `claude --plugin-dir ./plugins/ruview` from a clone) gives newcomers and operators the whole RuView workflow surface; no MCP-server prerequisite; Codex users get the same operator commands; the smoke script makes drift visible.
+- **Cost:** a mega-plugin means coarser install granularity (you get all 9 skills or none); the Codex mirror must be kept in sync by hand (the smoke script checks command↔prompt *presence* parity, not content parity); a skill stem (`ruview-verify`) collides with a command stem — tolerated by Claude Code (both resolve), but `claude plugin details` lists it twice.
+- **Follow-ups:** if the skill set grows past comfortable browsing (it's at 9), revisit the "one mega-plugin" decision and split by lifecycle (`ruview-edge`, `ruview-train`, …); add a *content*-parity lint between commands and Codex prompts; consider renaming `/ruview-verify` to drop the skill/command stem collision; consider pinning a tested `claude-flow` CLI minor for the security-scan step if that step becomes load-bearing; verify the underlying RuView command flags (`sensing-server --help`, `gcloud-train.sh`, `provision.py`) against the live tree rather than from README/scripts.

Use for research-grade or multi-node deployments.

+
+# RuView Advanced Sensing
+
+The deep end: multistatic mesh, tomography, persistent field models, and the security model that protects them. Most of this lives in `wifi-densepose-signal/src/ruvsense/` (14 modules) and `wifi-densepose-ruvector/src/viewpoint/` (5 modules).
+
+## RuvSense multistatic mode (ADR-029)
+
+Treat every WiFi link in range — including neighbours' APs — as a bistatic radar pair, then fuse them.
+
+| Module (`signal/src/ruvsense/`) | Purpose |
+|--------------------------------|---------|
+| `multiband.rs` | Multi-band CSI frame fusion, cross-channel coherence |
+| `phase_align.rs` | Iterative LO phase-offset estimation, circular mean |
+| `multistatic.rs` | Attention-weighted fusion, geometric diversity |
+| `coherence.rs` / `coherence_gate.rs` | Z-score coherence scoring; Accept / PredictOnly / Reject / Recalibrate gate decisions |
+| `pose_tracker.rs` | 17-keypoint Kalman tracker with AETHER re-ID embeddings |
+| `field_model.rs` | SVD room eigenstructure, perturbation extraction |
+| `tomography.rs` | RF tomography, ISTA L1 solver, voxel grid |
+| `longitudinal.rs` | Welford stats, biomechanics drift detection |
+| `intention.rs` | Pre-movement lead signals (200–500 ms ahead) |
+| `cross_room.rs` | Environment fingerprinting, transition graph |
+| `gesture.rs` | DTW template-matching gesture classifier |
+| `adversarial.rs` | Physically-impossible-signal detection, multi-link consistency |
+
+## Cross-viewpoint fusion (ADR-016 viewpoint module)
+
+Combine 2+ nodes geometrically — more nodes, more independent looks, tighter localization.
+
+| Module (`ruvector/src/viewpoint/`) | Purpose |
+|------------------------------------|---------|
+| `attention.rs` | CrossViewpointAttention, GeometricBias, softmax with `G_bias` |
+| `geometry.rs` | GeometricDiversityIndex, Cramér–Rao bounds, Fisher Information |
+| `coherence.rs` | Phase-phasor coherence, hysteresis gate |
+| `fusion.rs` | MultistaticArray aggregate root, domain events |
+
+Host-side helpers to explore the geometry before deploying: `node scripts/mesh-graph-transformer.js`, `node scripts/passive-radar.js`, `node scripts/deep-scan.js`.
+
+## Persistent field model (ADR-030)
+
+`field_model.rs` builds an SVD eigenstructure of the room and stores it (RVF, ideally on a Cognitum Seed). New CSI frames are projected against it; the residual *is* the perturbation. Lets you ask "what's different from the empty-room baseline?" and survive restarts.
+
+## RF tomography
+
+`tomography.rs` reconstructs a voxel occupancy grid from the multistatic link set via an ISTA L1 solver (sparse — most voxels are empty). Use with cross-viewpoint geometry for through-wall volumetric imaging. RuVector solver crates back the sparse interpolation (114→56 subcarriers).
+
+## Sensing-first RF mode & adaptive mesh kernel
+
+- ADR-031 (RuView sensing-first RF mode), ADR-081 (adaptive CSI mesh firmware kernel), ADR-083 (per-cluster π compute hop), ADR-095/096 (on-ESP32 temporal modeling with sparse GQA attention — runs the temporal head on-device).
+
+## Security (ADR-032 — multistatic mesh hardening)
+
+Using neighbours' APs as illuminators and pooling links across a mesh expands the attack surface. Mitigations:
+- `adversarial.rs` rejects physically impossible signals and cross-checks multi-link consistency.
+- `coherence_gate.rs` quarantines low-coherence / suspicious links (Reject / Recalibrate).
+- Ed25519 witness chain (ADR-028) attests every measurement.
+- Run a security review when touching anything on the hardware/network boundary (see `ruview-verify` and `docs/security-audit-wasm-edge-vendor.md`).

+
+## Picking the right modality
+
+- **Through a wall, no line of sight** → presence + activity; expect ≤5 m depth (Fresnel-zone geometry).
+- **Person stationary (sleeping / sitting)** → vitals (breathing first, heart rate needs cleaner signal) + sleep staging.
+- **Need skeletons** → pose (WiFlow). Camera-free works but is modest; camera-supervised gets 92.9% PCK@20 — train it (`ruview-model-training`).
+- **Search & rescue** → MAT (`docs/wifi-mat-user-guide.md`).
+- **"What changed in this room?"** → environment mapping / RF fingerprint index.
+- **Best spatial accuracy** → 2+ ESP32 nodes + cross-viewpoint fusion (`ruview-advanced-sensing`), optionally + Cognitum Seed.

+# RuView CLI, API & WASM
+
+The programmatic surfaces of RuView — the `wifi-densepose` binary, the HTTP API, and the WebAssembly builds.
+
+## 1. The `wifi-densepose` CLI binary (`wifi-densepose-cli`)
+
+```bash
+cd v2
+cargo run -p wifi-densepose-cli -- --help        # or: cargo build -p wifi-densepose-cli --release  → target/release/wifi-densepose
+cargo run -p wifi-densepose-cli -- version
+```
+
+Top-level subcommands: `version`, and `mat` (Mass Casualty Assessment Tool).
+
+### `wifi-densepose mat …` — disaster survivor detection
+
+| Subcommand | Purpose | Key flags |
+|------------|---------|-----------|
+| `mat scan [zone]` | Start scanning for survivors | `--disaster-type <…>`, `--sensitivity 0.0–1.0`, `--max-depth <m>`, `--continuous`, `--interval <ms>`, `--simulate` |
+| `mat status` | Current scan status | `--detailed`, `--format <…>`, `--watch` |
+| `mat zones …` | Manage scan zones | `zones list [--active-only]`, plus add/remove/update |
+| `mat survivors` | List detected survivors with triage status | |
+| `mat alerts` | View / manage alerts | |
+| `mat export` | Export scan data | JSON or CSV |
+
+Example:
+```bash
+cargo run -p wifi-densepose-cli -- mat scan rubble-A --disaster-type earthquake --sensitivity 0.7 --max-depth 5 --continuous --interval 2000
+cargo run -p wifi-densepose-cli -- mat survivors --format json
+cargo run -p wifi-densepose-cli -- mat export --format csv > survivors.csv
+```
+
+Use `--simulate` for testing without hardware. Background and user guide: `docs/wifi-mat-user-guide.md`, `wifi-densepose-mat` crate.
+
+## 2. REST API (`wifi-densepose-api`, Axum)
+
+Library crate (`v2/crates/wifi-densepose-api/src/lib.rs`) — the Axum router/handlers; configured via the `wifi-densepose-config` crate. It's wired into the server binaries (e.g. the sensing server / Docker image), not a standalone `cargo run` target by itself.
+
+```bash
+# Easiest way to exercise it: the Docker image exposes the API + dashboard on :3000
+docker run -p 3000:3000 ruvnet/wifi-densepose:latest
+# Then hit the HTTP endpoints (see the API module / docs for routes) and open http://localhost:3000
+
+# v1 Python service config reference: example.env, pyproject.toml (archive/v1/)
+```
+
+When embedding the API crate in your own binary, take the router from `wifi_densepose_api`, supply config via `wifi-densepose-config`, and serve with Axum/Tokio. Keep input validation at the boundary (project rule).
+
+## 3. WASM / browser & ESP32-WASM3
+
+- **`wifi-densepose-wasm`** — compiles the stack to `wasm32-unknown-unknown` with a JS-friendly API:
+  ```bash
+  cd v2/crates/wifi-densepose-wasm
+  wasm-pack build --target web --features mat        # recommended (produces pkg/)
+  cargo build --target wasm32-unknown-unknown --features mat   # plain cargo build
+  ```
+  See `v2/crates/wifi-densepose-wasm/README.md` for the exported surface.
+- **`wifi-densepose-wasm-edge`** — 60 edge modules (609 tests) that compile to `wasm32-unknown-unknown` and run on ESP32-S3 via WASM3; shared utils in `src/vendor_common.rs`. These are the ADR-041 edge-intelligence modules in WASM form.
+- Browser demos: pose-fusion (ADR-059), point-cloud (ADR-094) — deployed via GitHub Pages from the WASM build.
+
+## 4. Where it fits
+
+| You want to… | Use |
+|--------------|-----|
+| Script a survivor scan / export results | `wifi-densepose mat …` |
+| Expose sensing over HTTP | `wifi-densepose-api` (via a server binary / Docker) |
+| Run sensing in a browser | `wifi-densepose-wasm` → `wasm-pack build --target web` |
+| Run an edge module on an ESP32 in WASM | `wifi-densepose-wasm-edge` + WASM3 |
+| A long-running CSI sink + training | `wifi-densepose-sensing-server` (see `ruview-applications` / `ruview-model-training`) |
+

+allowed-tools: Bash Read Write Edit Glob Grep
+---
+
+# RuView Configuration
+
+Everything you can tune in a RuView deployment, from a one-line provision flag to a full mesh + Cognitum Seed setup.
+
+## 1. Firmware build-time config (sdkconfig)
+
+| Variant | File | When |
+|---------|------|------|
+| 8MB (default) | `firmware/esp32-csi-node/sdkconfig.defaults.template` | ESP32-S3 8MB, full feature set, real WiFi CSI |
+| 4MB | `firmware/esp32-csi-node/sdkconfig.defaults.4mb` | ESP32-S3 SuperMini 4MB — display disabled, dual OTA slots (`partitions_4mb.csv`, ~1.856 MB each) |
+| Heltec N16R2 | `firmware/esp32-csi-node/sdkconfig.defaults.heltec_n16r2` | Heltec boards |
+
+Switch: `cp firmware/esp32-csi-node/sdkconfig.defaults.<variant> firmware/esp32-csi-node/sdkconfig.defaults`, then rebuild (see `ruview-hardware-setup`). **Never test in mock mode** — the Kconfig fall-threshold bug only showed up with real CSI.
+
+## 2. Runtime device config (NVS via provision.py)
+
+`provision.py` writes the `csi_cfg` NVS namespace over the serial port. **Run `python firmware/esp32-csi-node/provision.py --help` for the authoritative flag list** (on Windows force `PYTHONUTF8=1 PYTHONIOENCODING=utf-8` — the help text contains non-ASCII and crashes under cp1252).
+
+```bash
+python firmware/esp32-csi-node/provision.py --port COM8 \
+  --ssid "WiFi" --password "secret" \
+  --target-ip 192.168.1.20 --target-port 5005 \   # aggregator UDP sink (port default 5005)
+  --node-id 1 \                                   # 0-255
+  --channel 6 --filter-mac AA:BB:CC:DD:EE:FF       # ADR-060: pin channel + filter transmitter
+```
+
+| Flag group | Flags | Notes |
+|------------|-------|-------|
+| WiFi / sink | `--ssid` `--password` `--target-ip` `--target-port` (5005) `--node-id` | `--node-id` 0-255 |
+| TDM mesh | `--tdm-slot` `--tdm-total` | 0-based slot index + total node count — this is how multi-node mesh is slotted |
+| Edge processing | `--edge-tier {0,1,2}` | 0=off, 1=stats, 2=vitals (ADR-041) |
+| Detection thresholds | `--pres-thresh` (50) `--fall-thresh` (15000 → 15.0 rad/s²) | raise `--fall-thresh` to cut false falls in high-traffic areas (issue #263) |
+| Vitals | `--vital-win` (300 frames) `--vital-int` (1000 ms) `--subk-count` (32, top-K subcarriers) | |
+| Channel / hopping | `--channel` (1-14 / 36-177, overrides AP auto-detect) `--filter-mac` `--hop-channels` (`1,6,11`) `--hop-dwell` (200 ms) | omit `--channel` + set `--hop-channels` for ADR-061 multi-freq hopping; omit `--filter-mac` to capture all transmitters |
+| Cognitum Seed | `--seed-url` (`http://10.1.10.236`) `--seed-token` (Bearer, from pairing) `--zone` (`lobby`) | |
+| Swarm | `--swarm-hb` (30 s) `--swarm-ingest` (5 s) | heartbeat + vector ingest intervals |
+| Mode | `--dry-run` (build NVS bin, don't flash) `--baud` (460800) `--force-partial` | |
+
+> ⚠️ **NVS namespace is replaced wholesale (issue #391).** Flashing rewrites the *entire* `csi_cfg` namespace — **any key you don't pass on the CLI is erased**. Always pass the full set you want, or use `--force-partial` knowingly. Read the device's current values off the serial boot log first (`adaptive_ctrl` / `csi_collector` lines) if you're unsure.
+
+- NVS partition images for fleet provisioning: `scripts/generate_nvs_matrix.py` (subprocess-first — the `esp_idf_nvs_partition_gen` API changed across versions).
+
+## 3. Sensing server flags
+
+```bash
+cd v2
+cargo run -p wifi-densepose-sensing-server -- --help
+
+# Common modes:
+cargo run -p wifi-densepose-sensing-server                                  # live sink, default port
+cargo run -p wifi-densepose-sensing-server -- --pretrain --dataset data/csi/ --pretrain-epochs 50
+cargo run -p wifi-densepose-sensing-server -- --train --dataset data/mmfi/ --epochs 100 --save-rvf model.rvf
+cargo run -p wifi-densepose-sensing-server -- --model model.rvf --embed
+cargo run -p wifi-densepose-sensing-server -- --model model.rvf --build-index env
+```
+
+`wifiscan` server (multi-BSSID, ADR-022): `cargo run -p wifi-densepose-sensing-server` consumes `wifi-densepose-wifiscan` output; use neighbour APs as free radar illuminators.
+
+## 4. Edge intelligence modules (ADR-041)
+
+Small Rust/WASM programs that run on the ESP32 itself — no internet, instant response. See `docs/edge-modules/` and `docs/adr/ADR-041-*`. Each module declares its CSI feature inputs (8-dim feature vectors) and an RVF store target (Cognitum Seed). Configure which modules ship in a build via the firmware component config; configure their thresholds via NVS keys.
+
+Helper scripts that mirror edge-module logic on the host (useful for tuning before flashing):
+`scripts/apnea-detector.js`, `gait-analyzer.js`, `material-classifier.js`, `passive-radar.js`, `mincut-person-counter.js`, `device-fingerprint.js`, `mesh-graph-transformer.js`, `material-detector.js`.
+
+## 5. Multi-node mesh
+
+- 2+ nodes give real spatial resolution. Each node provisioned to the same `--target-ip` sink.
+- TDM protocol + channel hopping coordinated by `wifi-densepose-hardware` (`v2/crates/wifi-densepose-hardware/src/esp32/`).
+- Cross-viewpoint fusion combines nodes — see `ruview-advanced-sensing`.
+
+## 6. Cognitum Seed integration ($140 total BOM)
+
+ESP32 streams CSI → bridge forwards to a Cognitum Seed for persistent RVF memory, kNN over environments, and an Ed25519 witness chain.
+
+```bash
+node scripts/rf-scan.js --port 5006              # live RF room scan → Seed
+node scripts/snn-csi-processor.js --port 5006    # SNN real-time learning on-Seed
+```
+
+See `docs/tutorials/cognitum-seed-pretraining.md` and ADR-028 (capability audit + witness verification).
+
+## 7. App-level config
+
+- API: `wifi-densepose-api` (Axum) — config via `wifi-densepose-config` crate; see `example.env` / `pyproject.toml` for the v1 Python service.
+- Docker: `docker run -p 3000:3000 ruvnet/wifi-densepose:latest` (env-var overrides documented in `README.md` / `docker/`).
+- Dashboard: served on `:3000`; nvsim dashboard (ADR-092) is separate.
+
+## Reference
+
+- `docs/adr/` (96 ADRs) — esp. ADR-022 (wifiscan), ADR-028 (capability audit), ADR-041 (edge modules), ADR-060 (channel/MAC override), ADR-061 (QEMU + mesh), ADR-081 (adaptive CSI mesh kernel)

+
+**Not supported:** original ESP32, ESP32-C3 (single-core).
+
+## 1. Build firmware (Windows — Python subprocess, NOT bash directly)
+
+ESP-IDF v5.4 does not support MSYS2/Git Bash. Use the Espressif Python venv as a subprocess with `MSYSTEM*` env vars stripped. The proven command lives in `CLAUDE.local.md` — reproduce it:
+
+```bash

+import subprocess, os
+env = os.environ.copy()
+for k in ['MSYSTEM','MSYSTEM_CHOST','MSYSTEM_PREFIX','MINGW_PREFIX','CHERE_INVOKING']:
+    env.pop(k, None)

+print(r.stdout[-3000:]); print(r.stderr[-2000:]); print('RC:', r.returncode)

+
+- **8MB build:** uses `sdkconfig.defaults.template` (no mock — real WiFi CSI).
+- **4MB build:** `cp firmware/esp32-csi-node/sdkconfig.defaults.4mb firmware/esp32-csi-node/sdkconfig.defaults` first, then build.
+- Build outputs: `firmware/esp32-csi-node/build/{bootloader/bootloader.bin, partition_table/partition-table.bin, esp32-csi-node.bin, ota_data_initial.bin}`.
+
+## 2. Flash to the device
+
+Same subprocess pattern, swap `[python, idf_py, 'build']` → `[python, idf_py, '-p', 'COM8', 'flash']`. Or with esptool directly:
+
+```bash
+python -m esptool --chip esp32s3 --port COM8 --baud 460800 \
+  write_flash 0x0 firmware/esp32-csi-node/build/bootloader/bootloader.bin \
+  0x8000 firmware/esp32-csi-node/build/partition_table/partition-table.bin \
+  0xf000 firmware/esp32-csi-node/build/ota_data_initial.bin \
+  0x20000 firmware/esp32-csi-node/build/esp32-csi-node.bin
+```
+
+(The default device port in this workspace is **COM8**. Some docs reference COM9 — confirm with the user.)
+
+## 3. Provision WiFi + sink address
+
+Runs directly — no ESP-IDF env needed:
+
+```bash
+python firmware/esp32-csi-node/provision.py --port COM8 \
+  --ssid "YourWiFi" --password "secret" --target-ip 192.168.1.20 --target-port 5005 --node-id 1
+
+# Optional ADR-060 overrides:
+python firmware/esp32-csi-node/provision.py --port COM8 --channel 6 --filter-mac AA:BB:CC:DD:EE:FF
+```
+
+`--help` lists the full flag set (TDM mesh slotting, edge tier, detection thresholds, vitals window, hop channels, Cognitum Seed, swarm intervals) — see the `ruview-configure` skill for the table. **Gotcha (issue #391):** flashing replaces the *entire* `csi_cfg` NVS namespace — any key not on the CLI is erased; pass the full set you want. On Windows, `provision.py --help` needs `PYTHONUTF8=1` to print (non-ASCII in the help text).
+
+## 4. Confirm CSI stream
+
+```bash
+# Serial monitor (use pyserial — idf.py monitor hangs in a subprocess)
+/c/Espressif/tools/python/v5.4/venv/Scripts/python.exe -c "
+import serial, time
+ser = serial.Serial('COM8', 115200, timeout=1); start = time.time()
+while time.time() - start < 15:
+    line = ser.readline()
+    if line: print(line.decode('utf-8', errors='replace').strip())
+ser.close()
+"
+```
+
+Then start the sink and watch frames arrive:
+```bash
+cd v2 && cargo run -p wifi-densepose-sensing-server   # listens for ESP32 UDP CSI
+```
+
+## Common issues
+
+| Symptom | Cause | Fix |
+|---------|-------|-----|
+| `MSys/Mingw is no longer supported` | ESP-IDF detected Git Bash | Use the Python-subprocess command above with `MSYSTEM*` stripped |
+| `cmd.exe /C` hangs | Interactive prompt from Git Bash | Don't use `cmd.exe /C` — use the Python subprocess |
+| `cmake not found` | Wrong path | It's `cmake\3.30.2\cmake-3.30.2-windows-x86_64\bin`, not `cmake\3.30.2\bin` |
+| `python_env not found` | Missing env var | Set `IDF_PYTHON_ENV_PATH=C:\Espressif\tools\python\v5.4\venv` |
+| No CSI frames at the sink | WiFi not provisioned, wrong channel, or MAC filter too tight | Re-run `provision.py`; try `--channel` matching your AP; drop `--filter-mac` |
+| False fall alerts | Old `fall_thresh` default | Issue #263 raised it to 15.0 rad/s² + debounce — reflash latest firmware |
+
+## Firmware release process (for maintainers)
+
+1. Build 8MB from `sdkconfig.defaults.template` (no mock)
+2. Build 4MB from `sdkconfig.defaults.4mb` (no mock)
+3. Save 6 binaries: `esp32-csi-node.bin`, `bootloader.bin`, `partition-table.bin`, `ota_data_initial.bin`, `esp32-csi-node-4mb.bin`, `partition-table-4mb.bin`
+4. `git tag v0.X.Y-esp32 && git push origin v0.X.Y-esp32`
+5. `gh release create v0.X.Y-esp32 <binaries> --title "..." --notes-file ...`
+6. Verify on real hardware (COM8) before publishing — **always test with real WiFi CSI, not mock mode** (mock missed the Kconfig threshold bug)

+
+# RuView mmWave / FMCW Radar
+
+The radio side-channel: 60 GHz and 24 GHz FMCW radar, standalone and fused with WiFi CSI.
+
+## Hardware
+
+| Device | Port | Band | Provides | ~Cost |
+|--------|------|------|----------|-------|
+| ESP32-C6 + Seeed MR60BHA2 | COM4 (typical) | 60 GHz FMCW | Heart rate, breathing rate, presence | ~$15 |
+| HLK-LD2410 | — | 24 GHz FMCW | Presence + distance (gated zones) | ~$3 |
+
+The C6 is RISC-V and can run the radar pipeline; it is **not** a WiFi-CSI node (use an ESP32-S3 for CSI). LD2410 is a UART module wired to a host or to the C6.
+
+## 1. Firmware with mmWave fusion (v0.5.0+)
+
+The ESP32 firmware auto-detects an attached MR60BHA2 or LD2410 and emits **48-byte fused vitals** records (CSI-derived + radar-derived, reconciled). Binary is ~12 KB larger than the CSI-only build. Build/flash as in `ruview-hardware-setup` (Windows: Python-subprocess; ESP-IDF v5.4 ≠ Git Bash). Recommended stable firmware tag: `v0.5.0-esp32` or later — see `docs/user-guide.md` release table.
+
+```bash
+# Provision the radar/fusion node (same provision.py; the firmware probes for the radar on boot)
+python firmware/esp32-csi-node/provision.py --port COM8 --ssid "WiFi" --password "secret" --target-ip 192.168.1.20
+# Confirm: serial monitor should report which radar was detected and start emitting fused vitals
+```
+
+## 2. mmWave ↔ WiFi-CSI fusion bridge (host side)
+
+```bash
+python scripts/mmwave_fusion_bridge.py            # bridges radar HR/BR + CSI → unified spatial model
+node scripts/passive-radar.js                     # passive-radar style processing for exploration
+```
+
+The 3D point-cloud demo fuses **camera depth (MiDaS) + WiFi CSI + mmWave radar** → unified spatial model (~22 ms pipeline, 19K+ pts/frame; ADR-094). Drive it with `scripts/mmwave_fusion_bridge.py` plus the point-cloud front-end.
+
+## 3. Standalone radar use
+
+- **MR60BHA2 (60 GHz)** — best for contactless vitals on a (near-)stationary subject: blood pressure proxy, heart rate, breathing rate; $15 hardware, no wearable. See `examples/medical/README.md`.
+- **LD2410 (24 GHz)** — best for cheap presence + coarse distance / gated zones; complements CSI presence (PIR-style fusion) for higher confidence.
+
+## 4. When to use mmWave vs. WiFi CSI
+
+| Situation | Prefer |
+|-----------|--------|
+| Contactless vitals, subject stationary, line of sight | **MR60BHA2** (cleaner HR/BR than CSI alone) |
+| Cheap, robust presence / occupancy in a defined zone | **LD2410** (or LD2410 + CSI) |
+| Through-wall presence / activity, no line of sight | **WiFi CSI** (mmWave doesn't penetrate walls) |
+| Pose / skeletons | **WiFi CSI** (WiFlow) — mmWave doesn't do this here |
+| Highest-confidence vitals | **Fusion** — 48-byte fused vitals reconcile CSI + radar |
+| Volumetric 3D | **Fusion** — camera depth + CSI + mmWave point cloud |
+

Use when building, fine-tuning, evaluating, or shipping a model.
+allowed-tools: Bash Read Write Edit Glob Grep
+---
+
+# RuView Model Training
+
+RuView trains several kinds of model. Pick the track that matches the goal; all of them run on a laptop, with an optional GPU path.
+
+## Track A — Camera-free pose (WiFlow), no cameras, no labels
+
+Trains 17-keypoint pose from 10 sensor signals. Fast, fully unsupervised, modest accuracy.
+
+```bash
+cd v2
+# Pretrain on raw CSI (contrastive)
+cargo run -p wifi-densepose-sensing-server -- --pretrain --dataset data/csi/ --pretrain-epochs 50
+# Train pose head, save an RVF artifact
+cargo run -p wifi-densepose-sensing-server -- --train --dataset data/mmfi/ --epochs 100 --save-rvf model.rvf
+```
+
+~84 s on an M4 Pro. Benchmarks: `node scripts/benchmark-wiflow.js`, eval: `node scripts/eval-wiflow.js`.
+
+## Track B — Camera-supervised pose (ADR-079) → 92.9% PCK@20
+
+Uses a webcam + MediaPipe as ground truth, paired with ESP32 CSI. ~19 min on a laptop.
+
+```bash
+# 1. Collect paired data (camera + CSI)
+python scripts/collect-ground-truth.py        # MediaPipe pose landmarks
+python scripts/collect-training-data.py       # CSI capture, time-synced
+node scripts/align-ground-truth.js            # align camera ↔ CSI timestamps
+
+# 2. Train (the camera-supervised path through the sensing-server / train crate)
+cd v2
+cargo run -p wifi-densepose-sensing-server -- --train --dataset data/paired/ --epochs <N> --save-rvf model.rvf
+
+# 3. Evaluate
+cd .. && node scripts/eval-wiflow.js          # reports PCK@20
+```
+
+Requires `data/pose_landmarker_lite.task` (MediaPipe model). See `docs/adr/ADR-079-camera-ground-truth-training.md`.
+
+## Track C — RuVector contrastive embeddings (AETHER, ADR-024)
+
+CSI subcarrier amplitude/phase → embeddings for re-ID and retrieval (171K emb/s on M4 Pro). Driven by `wifi-densepose-train` + `wifi-densepose-ruvector` (RuVector v2.0.4). Spectrogram embeddings: ADR-076.
+
+```bash
+cd v2
+cargo check -p wifi-densepose-train --no-default-features      # sanity
+cargo run -p wifi-densepose-sensing-server -- --model model.rvf --embed
+cargo run -p wifi-densepose-sensing-server -- --model model.rvf --build-index env
+```
+
+## Track D — Domain generalization (MERIDIAN, ADR-027)
+
+Make a model transfer across environments without retraining. Configured through the training pipeline's domain-generalization options; see ADR-027 and `wifi-densepose-train` + `ruview_metrics`.
+
+## Track E — Local SNN environment adaptation
+
+Spiking neural network that adapts to a new room in <30 s, on-device or on a Cognitum Seed:
+
+```bash
+node scripts/snn-csi-processor.js --port 5006
+```
+
+See `docs/tutorials/cognitum-seed-pretraining.md`, ADR-084/085 (RaBitQ similarity sensor), ADR-086 (edge novelty gate).
+
+## GPU training on GCloud
+
+Project `cognitum-20260110` has L4 / A100 / H100 quota.
+
+```bash
+gcloud auth login
+gcloud config set project cognitum-20260110
+
+bash scripts/gcloud-train.sh --dry-run                      # smoke test, synthetic data
+bash scripts/gcloud-train.sh --gpu l4 --hours 2             # prototyping
+bash scripts/gcloud-train.sh --gpu a100 --config scripts/training-config-sweep.json
+bash scripts/gcloud-train.sh --sweep                        # full hyperparameter sweep
+# VM is auto-deleted after training unless --keep-vm. Cost: L4 ~$0.80/hr, A100 40GB ~$3.60/hr.
+```
+
+Local Mac training: `bash scripts/mac-mini-train.sh`. Model benchmark: `python scripts/benchmark-model.py`.
+
+## Publishing a trained model
+
+```bash
+python scripts/publish-huggingface.py        # or: bash scripts/publish-huggingface.sh
+```
+
+Pushes the RVF artifact + card to Hugging Face. See `docs/huggingface/`.
+
+## Data layout
+
+| Path | Contents |
+|------|----------|
+| `data/recordings/` | Raw CSI captures (`*.csi.jsonl`), overnight runs |
+| `data/csi/` | CSI datasets for pretraining |
+| `data/mmfi/` | MM-Fi dataset (ADR-015) |
+| `data/paired/` | Camera ↔ CSI paired samples (ADR-079) |
+| `data/ground-truth/` | MediaPipe pose landmarks |
+| `data/pose_landmarker_lite.task` | MediaPipe model file |
+| `models/` | Trained artifacts |
+
+Record more data: `python scripts/record-csi-udp.py` (UDP CSI capture from a live node).
+
+## Validation after a training change
+
+```bash
+cd v2 && cargo test --workspace --no-default-features          # 1,400+ pass, 0 fail
+cd .. && python archive/v1/data/proof/verify.py                # VERDICT: PASS
+```
+
+Then hand off to `ruview-verify` for the witness bundle.

+allowed-tools: Bash Read Write Edit Glob Grep
+---
+
+# RuView Quickstart
+
+Get a newcomer from zero to a running RuView sensing dashboard. Three tiers, pick the one that matches the hardware on hand.
+
+## Tier 0 — Docker, no hardware (2 minutes)
+
+```bash
+docker pull ruvnet/wifi-densepose:latest
+docker run -p 3000:3000 ruvnet/wifi-densepose:latest
+# open http://localhost:3000  — simulated CSI, full UI
+```
+
+Use this to demo the dashboard, explore the API, or develop UI without a sensor.
+
+## Tier 1 — Build the repo from source
+
+```bash
+# Rust workspace (1,400+ tests, ~2 min)
+cd v2
+cargo test --workspace --no-default-features
+
+# Single-crate sanity check (no GPU)
+cargo check -p wifi-densepose-train --no-default-features
+
+# Python proof (deterministic SHA-256 pipeline check)
+cd ..
+python archive/v1/data/proof/verify.py   # must print VERDICT: PASS
+```
+
+If `verify.py` fails on a hash mismatch after a numpy/scipy bump:
+```bash
+python archive/v1/data/proof/verify.py --generate-hash
+python archive/v1/data/proof/verify.py
+```
+
+## Tier 2 — Live sensing with an ESP32-S3 ($9)
+
+This is the real thing. Hand off to the `ruview-hardware-setup` skill for the flash/provision/monitor loop, then:
+
+```bash
+# Lightweight sensing server (consumes the ESP32 UDP CSI stream)
+cd v2
+cargo run -p wifi-densepose-sensing-server
+# Live RF room scan / SNN learning helpers:
+node ../scripts/rf-scan.js --port 5006
+node ../scripts/snn-csi-processor.js --port 5006
+```
+
+## What to know before you start
+
+- **ESP32-C3 and the original ESP32 are NOT supported** — single-core, can't run the CSI DSP pipeline. Use ESP32-S3 (8MB or 4MB) or ESP32-C6.
+- A **single ESP32** has limited spatial resolution — 2+ nodes (or add a Cognitum Seed) for good results.
+- Camera-free pose accuracy is limited (~84s to train, modest PCK). For 92.9% PCK@20 use camera-supervised training (see `ruview-model-training` skill, ADR-079).
+- No cloud, no internet, no cameras required — everything runs on edge hardware.
+
+## Next steps to suggest
+
+| Goal | Skill / command |
+|------|-----------------|
+| Flash & provision an ESP32 node | `ruview-hardware-setup` · `/ruview-flash` · `/ruview-provision` |
+| Tune channels / MAC filter / edge modules | `ruview-configure` |
+| Run a sensing application (presence, vitals, pose, sleep, MAT) | `ruview-applications` · `/ruview-app` |
+| Train a pose / sensing model | `ruview-model-training` · `/ruview-train` |

+
+# RuView Verification & Witness Bundle
+
+The trust pipeline for RuView. Run this after meaningful changes and before merging.
+
+## 1. Rust workspace tests
+
+```bash
+cd v2
+cargo test --workspace --no-default-features        # must be 1,400+ passed, 0 failed (~2 min)
+```
+

+
+## 2. Deterministic Python proof (Trust Kill Switch)
+
+Feeds a reference CSI signal through the **production** pipeline and hashes the output. Any behavioural drift changes the hash.
+
+```bash
+cd ..
+python archive/v1/data/proof/verify.py              # must print VERDICT: PASS

+- `test-results/rust-workspace-tests.log` — full cargo test output
+- `firmware-manifest/source-hashes.txt` — SHA-256 of all 7 ESP32 firmware files
+- `crate-manifest/versions.txt` — all 15 crates + versions
+- `VERIFY.sh` — one-command self-verification for recipients

+
+## Pre-merge checklist (from CLAUDE.md)
+
+1. Rust tests pass (1,400+, 0 fail)
+2. Python proof passes (VERDICT: PASS)
+3. `README.md` updated if scope changed (platform/crate/hardware tables, feature summaries)
+4. `CLAUDE.md` updated if scope changed (crate table, ADR list, module tables, version)
+5. `CHANGELOG.md` — entry under `[Unreleased]`
+6. `docs/user-guide.md` updated if new data sources / CLI flags / setup steps
+7. ADR index — bump ADR count in README docs table if a new ADR was added
+8. Witness bundle regenerated if tests or proof hash changed
+9. Docker Hub image rebuilt only if Dockerfile / deps / runtime behaviour changed
+10. Crate publishing only if a published crate's public API changed (publish in dependency order — see CLAUDE.md)
+11. `.gitignore` updated for new build artifacts/binaries
+12. Security review for new modules touching hardware/network boundaries
+
+## Security scan
+
+```bash
+npx @claude-flow/cli@latest security scan            # after security-related changes

+"""Fix-marker regression guard for RuView.
+
+Reads ``scripts/fix-markers.json`` and asserts that every previously-shipped
+fix is still present in the codebase:
+
+* every file listed in a marker must exist;
+* every ``require`` pattern must appear in at least one of the marker's files
+  (a missing pattern means the fix was probably reverted);
+* no ``forbid`` pattern may appear in any of the marker's files
+  (a re-appearing anti-pattern means the bug was re-introduced).
+
+A pattern is a literal substring by default. Wrap it in ``/.../`` to treat it
+as a (multiline, case-sensitive) regular expression, e.g. ``"/fall_thresh\\s*=\\s*2\\.0/"``.
+
+This is a stdlib-only script — no dependencies, runs anywhere Python 3.8+ does.

+//! Real-time CSI introspection tap (ADR-099).
+//!
+//! Per-frame state alongside the window-aggregated event pipeline. Two
+//! midstream primitives feed it:
+//!
+//! * `midstreamer-attractor` — Lyapunov exponent + attractor regime (point /
+//!   limit cycle / strange / unknown) over a sliding window of derived
+//!   amplitude scalars. Replaces the heuristic "is the room calm or moving"
+//!   threshold-on-EWMA with a physics-shaped continuous metric.
+//! * `midstreamer-temporal-compare` — DTW-style similarity matching of recent
+//!   CSI feature history against a labelled signature library
+//!   (`SignatureLibrary`). The top-k matches go into [`IntrospectionSnapshot`].
+//!
+//! The whole module is **never window-blocked**: every accepted [`CsiFrame`]
+//! triggers an `update_per_frame` call; the snapshot is fresh on every frame.
+//! That's the latency-win contract from ADR-099 D4 — the soonest a
+//! "shape recognised" signal can emit is **one frame** (≈33 ms at 30 Hz CSI),
+//! not one window (≈533 ms at 16-frame / 30 Hz).
+//!
+//! See [`docs/adr/ADR-099-midstream-introspection-tap.md`] for the architectural
+//! contract, the eight decisions, and the phased adoption plan.

+//! ADR-099 D8 benchmark — latency-floor measurement for the introspection tap
+//! vs. the window-aggregated event pipeline.
+//!
+//! What this measures (and what it doesn't):
+//!
+//! * It measures the **architectural floor** of each detection path:
+//!   - The window path's *soonest possible* `MotionDetected` emission is gated
+//!     by `WindowBuffer::new(16, 1 s)` + `MotionDetector::debounce_windows = 2`
+//!     = a known function of frames. No simulation of the EventPipeline is
+//!     needed for that floor — it's a deterministic count.
+//!   - The introspection path's "shape recognised" emission fires the first
+//!     frame after which `IntrospectionState::snapshot().top_k_similarity[0]
+//!     .above_threshold` is `true`. That's what we measure empirically.
+//! * It does *not* measure signature-library quality, DTW recall, or false
+//!   positives — those are P1 / P3 concerns. The bar this test checks is
+//!   D8's architectural latency-floor reduction (≥10× p99) on a clean
+//!   in-phase shape.
+//! * Per-frame `update()` wall-clock cost is also asserted (D4: ≤1 ms p99 on
+//!   a Pi-5-class host; checked here against a 10 ms loose bound that any
+//!   reasonable dev box should clear, leaving thermal/CI noise headroom).
+//!
+//! Numbers print at INFO level so `cargo test -- --nocapture` shows the
+//! comparison directly.

+//! crate ([`wifi_densepose_signal`]).
+//!
+//! Historically `wifi-densepose-signal` was listed as a dependency of this
+//! crate but never imported — the training pipeline only ever consumed the
+//! raw amplitude/phase tensors. This module wires the two together: it takes
+//! a windowed CSI observation and runs it through
+//! [`wifi_densepose_signal::features::FeatureExtractor`] to derive a compact,
+//! fixed-length feature vector (amplitude statistics, phase coherence, and a
+//! power-spectral-density summary).
+//!
+//! These derived features are the building block for a future vitals /
+//! multi-task supervision head (breathing-band and heart-rate-band power can
+//! be read off the PSD summary); for now they are produced on demand via
+//! [`extract_signal_features`] / [`crate::dataset::CsiSample::signal_features`]
+//! and are not yet fed back into the loss. Wiring them as a training target
+//! is tracked as a follow-up to the 2026-05-11 training-pipeline audit.
