 ## [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-097: Adopt rvCSI as RuView's primary CSI runtime
+
+| Field | Value |
+|-------|-------|
+| **Status** | Proposed |
+| **Date** | 2026-05-13 |
+| **Deciders** | ruv |
+| **Codename** | **rvCSI-in-RuView** |
+| **Relates to** | ADR-095 (rvCSI platform), ADR-096 (rvCSI crate topology / FFI), ADR-014 (SOTA signal processing in `wifi-densepose-signal`), ADR-016 (RuVector training pipeline integration), ADR-024 (AETHER contrastive embeddings), ADR-031 (RuView sensing-first RF mode), ADR-049 (cross-platform WiFi interface detection) |
+| **rvCSI repo** | [github.com/ruvnet/rvcsi](https://github.com/ruvnet/rvcsi) (vendored at `vendor/rvcsi`) |
+
+---
+
+## 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
+
+| Field | Value |
+|-------|-------|
+| **Status** | Proposed |
+| **Date** | 2026-05-13 |
+| **Deciders** | ruv |
+| **Codename** | **midstream-introspection** |
+| **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.

- * rvCSI — Nexmon CSI compatibility shim (napi-c layer, ADR-095 D2, ADR-096).
- *
- * This is the ONLY C in the rvCSI runtime. It is the seam against fragile
- * vendor/firmware byte formats; everything above this file is safe Rust.
- *
- * It exposes two record formats:
- *
- *  (1) the "rvCSI Nexmon record" — a compact, byte-defined, self-describing
- *      record (magic 'RVNX', RSSI, channel, timestamp, then interleaved int16
- *      I/Q in Q8.8 fixed point). Used by the recorder, replay, and tests.
- *
- *  (2) the *real* nexmon_csi UDP payload — what the patched Broadcom firmware
- *      (BCM43455c0 / 4358 / 4366c0, …) actually sends: an 18-byte header
- *      (magic 0x1111, RSSI, frame-control, source MAC, sequence, core/spatial
- *      stream, Broadcom chanspec, chip version) followed by `nsub` complex CSI
- *      samples. We implement the modern format (int16 LE I/Q interleaved — what
- *      CSIKit / csireader.py read for the 43455c0 et al.); the legacy packed-
- *      float export used by some 4339/4358 firmwares is a documented follow-up.
- *
- * Record (1) layout (all integers little-endian):
- *   off  size  field
- *     0     4  magic            = 0x52564E58  ('R','V','N','X')
- *     4     1  version          = RVCSI_NX_VERSION (1)
- *     5     1  flags            bit0: rssi present, bit1: noise floor present
- *     6     2  subcarrier_count N (1 .. RVCSI_NX_MAX_SUBCARRIERS)
- *     8     1  rssi_dbm         int8 (valid iff flags bit0)
- *     9     1  noise_dbm        int8 (valid iff flags bit1)
- *    10     2  channel          uint16
- *    12     2  bandwidth_mhz    uint16
- *    14     2  reserved         (0)
- *    16     8  timestamp_ns     uint64
- *    24   4*N  N pairs of int16 (i, q), interleaved, fixed-point Q8.8
- *   total = 24 + 4*N bytes;  stored int16 v maps to float v / 256.0

- *     3     1  fctl             uint8 (802.11 frame-control byte)

- *    10     2  seq_cnt          uint16 (802.11 sequence-control)

-//!
-//! The Raspberry Pi 5 carries the same **CYW43455 (BCM43455c0)** 802.11ac
-//! wireless as the Pi 3B+ / Pi 4 / Pi 400 — the chip with the most mature

-//! # rvCSI Nexmon adapter (napi-c boundary)
-//!
-//! Wraps the isolated C shim in `native/rvcsi_nexmon_shim.{c,h}` — the only C
-//! in the rvCSI runtime (ADR-095 D2, ADR-096). The shim parses a compact,
-//! byte-defined "rvCSI Nexmon record" (a normalized superset of the nexmon_csi
-//! UDP payload). Everything above [`ffi`] is safe Rust; all `unsafe` is
-//! confined to this crate, bounds-checked on the C side, and documented.
-//!
-//! Two source paths:
-//!
-//! * the compact, self-describing **rvCSI Nexmon record** — fed to
-//!   [`NexmonAdapter::from_bytes`] (records concatenated in a buffer/file);
-//! * the **real nexmon_csi UDP payload** inside a libpcap capture
-//!   (`tcpdump -i wlan0 dst port 5500 -w csi.pcap`) — fed to
-//!   [`NexmonPcapAdapter::open`] / [`NexmonPcapAdapter::parse`].
-//!
-//! Both yield `Pending` [`CsiFrame`]s; the runtime runs
-//! [`rvcsi_core::validate_frame`] on each before exposing it.

-//! runtime. It implements **FR4 of [ADR-095]** — *"reusable Rust
-//! signal-processing stages"* — as a small library of deterministic primitives
-//! plus a composable per-frame [`SignalPipeline`].
-//!
-//! The crate is split into three modules:
-//!
-//! * [`stages`] — pure per-vector DSP primitives operating on `&[f32]` /
-//!   `&mut [f32]`: [`mean`](stages::mean), [`variance`](stages::variance),
-//!   [`std_dev`](stages::std_dev), [`median`](stages::median),
-//!   [`remove_dc_offset`](stages::remove_dc_offset),
-//!   [`unwrap_phase`](stages::unwrap_phase),
-//!   [`moving_average`](stages::moving_average), [`ewma`](stages::ewma),
-//!   [`hampel_filter`](stages::hampel_filter) /
-//!   [`hampel_filter_count`](stages::hampel_filter_count),
-//!   [`short_window_variance`](stages::short_window_variance),
-//!   [`subtract_baseline`](stages::subtract_baseline). Failable stages report
-//!   [`DspError`](stages::DspError).
-//! * [`features`] — frame/window-level scalar features:
-//!   [`motion_energy`](features::motion_energy) /
-//!   [`motion_energy_series`](features::motion_energy_series),
-//!   [`presence_score`](features::presence_score),
-//!   [`confidence_score`](features::confidence_score),
-//!   [`breathing_band_estimate`](features::breathing_band_estimate) (heuristic,
-//!   FFT-free, meant to be quality-gated by the caller).
-//! * [`pipeline`] — the [`SignalPipeline`](pipeline::SignalPipeline): a tiny
-//!   configuration bag with a non-destructive `process_frame` step that cleans a
-//!   [`rvcsi_core::CsiFrame`]'s `amplitude` / `phase` vectors *after*
-//!   `rvcsi_core::validate_frame` has run, never touching validation state.
-//!
-//! Everything here is deterministic: the same input always produces the same
-//! output. There are no heavy dependencies — the math is hand-rolled.

-//! # rvCSI events — window aggregation + semantic event extraction (ADR-095 FR5)
-//!
-//! This crate turns a stream of validated [`rvcsi_core::CsiFrame`]s into
-//! [`rvcsi_core::CsiWindow`]s and then into [`rvcsi_core::CsiEvent`]s.
-//!
-//! The pipeline has three layers:
-//!
-//! 1. [`WindowBuffer`] — buffers exposable frames from one
-//!    `(session_id, source_id)` and emits a [`rvcsi_core::CsiWindow`] when a
-//!    frame-count or duration threshold is hit. Per-subcarrier statistics
-//!    (`mean_amplitude`, `phase_variance`) and the scalar `motion_energy`,
-//!    `presence_score` and `quality_score` are computed here.
-//! 2. [`EventDetector`] implementations — small, deterministic state machines
-//!    that consume windows and emit events:
-//!    [`PresenceDetector`], [`MotionDetector`], [`QualityDetector`] and
-//!    [`BaselineDriftDetector`].
-//! 3. [`EventPipeline`] — wires a [`WindowBuffer`] and a set of detectors
-//!    together and owns an [`rvcsi_core::IdGenerator`].
-//!
-//! Determinism: feeding the same frame stream through an [`EventPipeline`]
-//! always produces the same event list (modulo the ids, which are minted in a
-//! deterministic order). All "noise" in the tests comes from a tiny LCG, never
-//! from `rand`.

-# @ruv/rvcsi
-
-Node.js bindings (napi-rs) for **rvCSI** — the edge RF sensing runtime: ingest
-WiFi CSI from files / Nexmon dumps, validate and normalize it, run reusable DSP,
-emit typed presence / motion / quality / anomaly events, and export temporal
-embeddings to an RF-memory store. See [ADR-095](../../../docs/adr/ADR-095-rvcsi-edge-rf-sensing-platform.md)
-and [ADR-096](../../../docs/adr/ADR-096-rvcsi-ffi-crate-layout.md).
-
-> This package wraps the Rust crates in `v2/crates/rvcsi-*`. The Rust side does
-> all the work (parsing, validation, DSP, events, embeddings); this is a thin,
-> safe JS surface — nothing crosses the boundary except validated/normalized
-> objects (delivered as JSON the SDK parses for you).
-
-## Build
-
-The native addon is produced from the `rvcsi-node` Rust crate:
-
-```bash
-# from v2/crates/rvcsi-node
-npm install              # installs @napi-rs/cli
-npm run build            # -> rvcsi-node.<triple>.node + binding.js + binding.d.ts
-```
-
-(`cargo build -p rvcsi-node` also compiles the addon as a `cdylib`; `napi build`
-additionally emits the platform loader and `.d.ts`.)
-
-## Usage
-
-```js
-const { RvCsi, inspectCaptureFile, eventsFromCaptureFile, nexmonDecodeRecords } = require('@ruv/rvcsi');
-
-// One-shot: summarize a capture
-const summary = inspectCaptureFile('lab.rvcsi');
-console.log(summary.frame_count, summary.channels, summary.mean_quality);
-
-// One-shot: replay a capture into events
-for (const e of eventsFromCaptureFile('lab.rvcsi')) {
-  console.log(e.kind, e.timestamp_ns, e.confidence);
-}
-
-// Streaming
-const rt = RvCsi.openCaptureFile('lab.rvcsi');
-let frame;
-while ((frame = rt.nextCleanFrame()) !== null) {
-  // frame.validation is 'Accepted' | 'Degraded' | 'Recovered' — never 'Pending'/'Rejected'
-  if (frame.quality_score > 0.5) { /* ... */ }
-}
-const events = rt.drainEvents();
-console.log(rt.health());
-
-// Decode raw Nexmon records (the napi-c shim format) straight from a Buffer
-const fs = require('fs');
-const frames = nexmonDecodeRecords(fs.readFileSync('nexmon.bin'), 'wlan0', 1);
-```
-
-TypeScript types ship in `index.d.ts` (`CsiFrame`, `CsiWindow`, `CsiEvent`,
-`SourceHealth`, `CaptureSummary`, `ValidationStatus`, `CsiEventKind`, ...).
-
-## What's here vs. not (yet)
-
-Implemented: file/replay + Nexmon sources, the validation pipeline, the DSP
-stages, window aggregation + the event state machines, RuVector-style RF-memory
-export. Not yet wired into this addon: live radio capture, the WebSocket daemon,
-and the MCP tool server — those come with `rvcsi-daemon` / `rvcsi-mcp`.

-//! normalized rvCSI struct *serialized to JSON* or a scalar. Frames are run
-//! through [`rvcsi_core::validate_frame`] inside [`rvcsi_runtime`] before they
-//! reach JS (D6), so a JS caller never sees a `Pending` or `Rejected` frame.

-//! All real logic lives in the `rvcsi-runtime` crate (plain Rust, unit-tested
-//! without a Node env); the `#[napi]` items below are one-liner wrappers.
-//!
-//! ## JS surface (also see the generated `index.d.ts` in the npm package)
-//!
-//! Free functions:
-//! * `rvcsiVersion(): string`
-//! * `nexmonShimAbiVersion(): number` — ABI of the linked napi-c shim
-//! * `nexmonDecodeRecords(buf: Buffer, sourceId: string, sessionId: number): string`
-//!   — JSON array of validated `CsiFrame`s decoded from the C-shim record format
-//! * `inspectCaptureFile(path: string): string` — JSON `CaptureSummary`
-//! * `eventsFromCaptureFile(path: string): string` — JSON array of `CsiEvent`s
-//! * `exportCaptureToRfMemory(capturePath: string, outJsonlPath: string): number`

-//!
-//! This crate is a **standin** for the production RuVector vector-database
-//! binding (which gets wired in later). It provides:
-//!
-//! * deterministic, dependency-free embedding functions —
-//!   [`window_embedding`] / [`event_embedding`] / [`cosine_similarity`];
-//! * the [`RfMemoryStore`] trait plus value objects ([`EmbeddingId`],
-//!   [`RecordKind`], [`SimilarHit`], [`DriftReport`]);
-//! * two implementations: the in-process [`InMemoryRfMemory`] and the
-//!   file-backed [`JsonlRfMemory`] (JSONL append log, identical query semantics).
-//!
-//! Everything here is pure and deterministic given the same sequence of
-//! operations — no clocks, randomness, or order-dependent reductions — so
-//! captures replayed twice yield byte-identical stores and query results.
-//!
-//! ```
-//! use rvcsi_ruvector::{InMemoryRfMemory, RfMemoryStore, window_embedding};

+//! Opt-in bearer-token auth for the sensing-server HTTP API (#443).
+//!
+//! When the `RUVIEW_API_TOKEN` environment variable is set, every request
+//! whose path begins with `/api/v1/` must carry a matching
+//! `Authorization: Bearer <token>` header, otherwise the server responds with
+//! `401 Unauthorized`. When the env var is unset (or empty), the middleware is
+//! a no-op and the API stays unauthenticated — preserving the long-standing
+//! LAN-only deployment posture documented in the issue. This is a binary,
+//! deployment-time switch with **no default authentication change**.
+//!
+//! Endpoints outside `/api/v1/*` (`/health*`, `/ws/sensing`, the static `/ui/*`
+//! mount, `/`) are intentionally **not** gated:
+//! * `/health*` is the liveness/readiness probe that orchestrators hit
+//!   anonymously;
+//! * `/ws/sensing` and `/ui/*` are served to local browsers that can't easily
+//!   inject headers — the sensitive control plane is the `/api/v1/*` tree, and
+//!   that is what this layer protects.
+//!
+//! The header check uses a length-then-byte constant-time compare to avoid

+//! 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.
