release: ESP32-S3 firmware v0.6.5 — Tmr Svc stack + OTA init refactor (#628 )

Three fixes wrapped for the v0.6.5-esp32 release tag: 1. **`sdkconfig.defaults` adds `CONFIG_FREERTOS_TIMER_TASK_STACK_DEPTH=8192`**. The fix was already in `sdkconfig.defaults.template` (ADR-081, prevents "stack overflow in task Tmr Svc" bootloop when adaptive_controller emits feature_state from inside a Timer Svc callback). It was MISSING from the canonical `sdkconfig.defaults` file used by the build, so any fresh build picked up the 2 KiB FreeRTOS default and bootlooped on hardware. Verified on COM7: with the fix, no panics in 30 s of operation; without it, "***ERROR*** A stack overflow in task Tmr Svc has been detected." followed by sustained bootloop. 2. **`ota_update.c` extracts `ota_load_psk_from_nvs()` and calls it from both `ota_update_init()` and `ota_update_init_ex()`.** `main.c:230` uses the `_ex` variant, but only `ota_update_init()` was loading the PSK from NVS. Result: `s_ota_psk` stayed empty regardless of NVS contents, so the RuView#596 fail-closed posture rejected every request — but the diagnostic warning never printed at boot, leaving operators no signal about why their OTA uploads were 403'ing. Verified on COM7: W (3126) ota_update: NVS namespace 'security' not found — OTA upload endpoint will REJECT all requests until provisioned. Fail-closed per RuView#596. 3. **`version.txt`: 0.6.4 → 0.6.5**, paired with the v0.6.5-esp32 tag so the firmware-ci version-guard job (RuView#505 fix-marker) stays happy. Both validations done end-to-end on hardware (COM7, ESP32-S3 8MB, provisioned with --edge-tier 2 to also incidentally re-verify #438 is not reproducible on current main).
fix(firmware): OTA upload fails closed when no PSK in NVS (RuView#596 audit) (#623 )

 ## [Unreleased]

+### Security
+- **ESP32 OTA upload now fails closed when no PSK is provisioned** (#596 audit finding — critical, **breaking change for unprovisioned nodes**). `ota_check_auth()` previously returned `true` when `s_ota_psk[0] == '\0'`, so a freshly-flashed node would accept attacker-controlled firmware over plain HTTP on port 8032 from any host on the WiFi. No Secure Boot V2, no signed-image verification — a single LAN call could brick or backdoor a node. The fix rejects every OTA upload until a PSK is written to NVS (the OTA HTTP server still starts so operators can run `provision.py --ota-psk <hex>` over USB-CDC without reflashing). **Operators affected**: any deployment that relied on the unauthenticated OTA endpoint working out of the box now needs to provision a PSK before subsequent OTA pushes will succeed. Boot-time `ESP_LOGW` makes the new posture visible.
+- **Path-traversal vulnerabilities patched in five sensing-server endpoints** (closes #615 — critical). New `wifi_densepose_sensing_server::path_safety::safe_id()` enforces `[A-Za-z0-9._-]` only (no leading `.`, max 64 chars) before any user-controlled identifier reaches a `format!()` building a filesystem path. Applied at:
+  - `POST /api/v1/recording/start` (`recording.rs` — `session_name`)
+  - `GET /api/v1/recording/download/:id` (`recording.rs` — `id`)
+  - `DELETE /api/v1/recording/delete/:id` (`recording.rs` — `id`)
+  - `POST /api/v1/models/load` (`model_manager.rs` — `model_id`)
+  - `training_api.rs` `load_recording_frames` (`dataset_id`s)
+
+  Pre-fix, unauthenticated callers could read `../../etc/passwd`-style paths, write arbitrary JSONL files, load attacker-controlled `.rvf` model files, or delete arbitrary files the server process could touch. 9 unit tests in `path_safety::tests` exercise the rejection envelope (empty, too-long, path separators, parent-dir traversal, null byte, whitespace/specials, non-ASCII).
+
+### Fixed
+- **WebSocket `/ws/sensing` now reports `esp32:offline` when ESP32 hardware goes stale** (closes #618). `broadcast_tick_task` was re-emitting the cached `latest_update` with a frozen `source: "esp32"` field forever after the hardware lost power or network. The REST `/health` endpoint already called `effective_source()` (which returns `"esp32:offline"` after `ESP32_OFFLINE_TIMEOUT` = 5 s with no UDP frames), but the WS broadcast path was the one consumer that didn't. Result: the UI's "LIVE — ESP32 HARDWARE Connected" banner stayed green long after the hardware went away, and `vital_signs`/`features`/`classification` re-broadcasted the last-seen values indefinitely. Fix: clone the cached `latest_update` per tick, overwrite `source` with `s.effective_source()`, then serialize and broadcast. UI can now switch to an offline state on the same 5-second budget the REST surface uses.
+- **Proof replay (`archive/v1/data/proof/verify.py`) is now cross-platform deterministic** (closes #560). Three changes together: (1) `features_to_bytes()` now `np.round(.., HASH_QUANTIZATION_DECIMALS=6)`s each feature array before packing as little-endian f64, collapsing ULP-level drift from scipy.fft pocketfft SIMD reordering; (2) the `Verify Pipeline Determinism` workflow pins `OMP_NUM_THREADS=1`, `OPENBLAS_NUM_THREADS=1`, `MKL_NUM_THREADS=1`, `VECLIB_MAXIMUM_THREADS=1`, `NUMEXPR_NUM_THREADS=1` — multi-threaded BLAS reductions were a deeper source of non-determinism than SIMD reordering, and 6-decimal quantization alone wasn't enough across Azure VM microarchitectures; (3) `expected_features.sha256` regenerated under the new conditions. CI now passes the determinism check (same hash across consecutive runs on canonical Linux x86_64 CI runner: `667eb054c44ac510342665bf9c93d608868a8ead948ae8774b2796ebce6f8fe7`). `scripts/probe-fft-platform.py` updated to mirror `HASH_QUANTIZATION_DECIMALS=6` for cross-machine spot-checks.
+- **`archive/v1/src/services/pose_service.py:223` calls the right method on `PhaseSanitizer`** (closes #612). The call was `self.phase_sanitizer.sanitize(phase_data)`, but `PhaseSanitizer`'s full-pipeline entry point is named `sanitize_phase()` (`unwrap_phase` + `remove_outliers` + `smooth_phase` chained, see `archive/v1/src/core/phase_sanitizer.py:266`). The shorter `sanitize` name doesn't exist on the class, so any path that reached this branch raised `AttributeError` and crashed the pose service mid-frame.
+- **`adaptive_classifier.rs:94` no longer panics on NaN feature values** (closes #611).
+  `sorted.sort_by(|a, b| a.partial_cmp(b).unwrap())` returned `None` and panicked
+  whenever a single `NaN` reached the classifier from real ESP32 hardware (silent
+  DSP div-by-zero, empty buffer). One bad frame killed the entire sensing-server
+  process. Swapped for `unwrap_or(Ordering::Equal)`, matching the pattern the
+  same file already used at lines 149-150 and 155. Per-frame hot path; this was
+  a real production crash vector.
+- **`ui/utils/pose-renderer.js` no longer divides by zero** when two render frames land in the same `performance.now()` tick (issue #519 Bug 2). `deltaTime` is now `Math.max(currentTime - lastFrameTime, 1)` before the `1000 / deltaTime` division, capping displayed FPS at 1000 — far above any real render rate, but finite so the EMA `averageFps = averageFps * 0.9 + fps * 0.1` no longer poisons itself to `Infinity` on a single zero-dt tick.
+
+### Removed
+- **Stub crates `wifi-densepose-api`, `wifi-densepose-db`, `wifi-densepose-config`** (closes #578).
+  Each was a single-line doc-comment placeholder with an empty `[dependencies]`
+  section and zero references from any source file or `Cargo.toml`. The names
+  were reserved early for an envisioned REST/database/config split that never
+  materialised; the functionality they would provide is covered today by
+  `wifi-densepose-sensing-server` (Axum REST/WS), per-crate config + CLI args,
+  and the project's real-time-only (no-persistent-state) posture. Removing them
+  from the workspace prevents `cargo` from listing dead crates and shipping
+  empty published artifacts. If any of these names is needed in the future,
+  they can be reintroduced with a real implementation.
+
+### 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.

 **Fix:** Use the left USB-C port. On most ESP32-S3-DevKitC boards, the left port is the USB-to-UART bridge (CP2102/CH340) used for flashing and serial monitor. The right port is the native USB (USB-JTAG) which requires different drivers and isn't used by the RuView firmware.

+## 9. Docker Desktop on Windows drops UDP from multiple ESP32 nodes
+
+**Symptom:** Two or more ESP32 nodes are flashed, provisioned, and visibly transmit on the network — `tcpdump`/Wireshark on the Windows host shows datagrams from every node — but inside the Docker container only one source IP arrives. `/api/v1/sensing/latest` shows a single node and the live UI freezes or only tracks one body. Reported in #374 (4-node bench) and reproduced in #386 (6-node demo, RuView v0.7.0).
+
+**Root cause:** Docker Desktop on Windows runs the engine inside a WSL2 / Hyper-V VM. Inbound UDP from the host LAN is forwarded through `vpnkit` / `vEthernet` and the multi-source-IP datagrams are demultiplexed onto a single virtual socket. The first source-IP "wins"; subsequent unique sources are silently dropped at the VM boundary. This is a Docker Desktop limitation, not a sensing-server bug — `host.docker.internal` and `--network host` do not help (host networking is not implemented for the Linux engine on Windows).
+
+**Fix:** Run the bundled UDP relay on the host so every forwarded datagram arrives from the same loopback source IP, which Docker passes through unchanged.
+
+```powershell
+# 1. Start the relay (PowerShell or any terminal)
+python scripts/udp-relay.py --listen-port 5005 --forward-port 5006
+
+# 2. Edit docker/docker-compose.yml — change the ESP32 UDP mapping from
+#       - "5005:5005/udp"
+#    to
+#       - "5006:5005/udp"
+
+# 3. Bring the stack up
+docker compose -f docker/docker-compose.yml up
+```
+
+ESP32 nodes still target the host on `--target-ip <host>:5005` — no firmware re-provisioning is needed. The relay is `scripts/udp-relay.py` (stdlib only, no extra deps). Verify with `--verbose` that each node's source IP appears at least once before forwarding stabilises on a single ephemeral relay port.
+
+**Prevention:** Linux and macOS hosts are unaffected; the relay only needs to run on Docker Desktop for Windows. If Docker Desktop ships per-source UDP forwarding (tracked at [docker/for-win#1144](https://github.com/docker/for-win/issues/1144) and related), this workaround can be retired.
+
+**Prior art:** PR #413 (`txhno`) proposed a docs-only writeup of the same workaround; this entry supersedes it.
+
+---
+
+## 10. `404` on the visualization page when running sensing-server
+
+**Symptom:** `sensing-server` starts cleanly, logs `HTTP server listening on http://localhost:3000`, but loading `http://localhost:3000/` (or `/ui/index.html`) returns `404 Not Found`. Reported in #188.
+
+**Root cause:** The default `--ui-path ../../ui` is resolved relative to the binary's *current working directory*, not the binary location. When the binary is launched from anywhere other than `crates/wifi-densepose-sensing-server/`, the relative path doesn't reach the UI assets and Axum's static file handler returns 404.
+
+**Fix:** Pass an absolute UI path, run the binary from the crate directory, or use the Docker image (which bundles the UI under `/app/ui`).
+
+```bash
+# Option A — absolute path (recommended for production)
+sensing-server --source esp32 --udp-port 5005 --http-port 3000 \
+  --ws-port 3001 --ui-path /absolute/path/to/ui
+
+# Option B — run from the crate dir (works for local dev / cargo run)
+cd v2/crates/wifi-densepose-sensing-server
+cargo run -- --source esp32
+
+# Option C — Docker (no path config needed)
+docker compose -f docker/docker-compose.yml up sensing-server
+```
+
+**Prevention:** Track future work in #188 to fall back to a path resolved relative to the executable when the cwd-relative path doesn't exist, so the binary works regardless of where it's launched.
+
+---
+
+## 11. Boot loop on `--edge-tier 1` or `--edge-tier 2`
+
+**Symptom:** ESP32-S3 boots normally with `--edge-tier 0`, but flashing the same firmware with `--edge-tier 1` or `2` produces a boot loop. Serial output reaches `cpu_start` and `heap_init`, then resets repeatedly. Reported in #438 against firmware `v0.4.3.1-esp32-3-g66e2fa083-dir`.
+
+**Root cause:** Edge tiers 1 and 2 enable the on-device DSP pipeline on Core 1. In the affected build, the `edge_dsp` task ran a tight per-frame loop without yielding, so the FreeRTOS task watchdog tripped on Core 1 and panicked. Tier 0 is passthrough only and doesn't activate the pipeline, so the watchdog never fires there.
+
+**Fix:** Flash the [v0.4.3.1-esp32](https://github.com/ruvnet/RuView/releases/tag/v0.4.3.1-esp32) release or later — the DSP task yield fixes have shipped on `main` since the build in the report.
+
+```bash
+# Verify what version you're on (look for "App version" in serial output on boot)
+python -m serial.tools.miniterm COM7 115200
+# Expect: "App version: v0.4.3.1-esp32" or higher
+```
+

+# 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.

+| **Outcome** | Do **not** adopt as a system component. Two of midstream's six workspace crates (`temporal-compare`, `nanosecond-scheduler`) are plausible future-use building blocks; the rest do not fit. `vendor/midstream` is retained as a reference-only submodule. |
+
+---
+
+## 1. Context
+
+`vendor/midstream` is a git submodule of RuView (`.gitmodules:1-4`) but, like `vendor/rvcsi` was before ADR-097, it is **vendored but not consumed**: no `v2/crates/*/Cargo.toml` depends on a `midstreamer-*` crate, no Rust source contains `use midstreamer_…`, and the ESP32 firmware and TypeScript dashboard have no midstream imports.
+
+This ADR settles the standing question of *whether RuView should consume midstream at all*, and if so, where. The user-facing prompt enumerated four candidate seams to evaluate:
+
+1. Streaming / pub-sub for the WebSocket fan-out (today: `tokio::sync::broadcast::channel::<String>(256)` at `v2/crates/wifi-densepose-sensing-server/src/main.rs:4769`).
+2. Stream processing for the CSI → DSP → event pipeline (today: synchronous `EventPipeline` at `vendor/rvcsi/crates/rvcsi-events/src/pipeline.rs`, freshly adopted via ADR-097).
+3. Multi-source merging / TDM coordination for the ESP32 mesh (ADR-029, ADR-073).
+4. Backpressure / flow control between the UDP receiver and downstream consumers (`v2/crates/wifi-densepose-sensing-server/src/main.rs:3638` `udp_receiver_task`; firmware-side `stream_sender` ENOMEM backoff at `firmware/esp32-csi-node/main/csi_collector.c:223-228`).
+
+To evaluate each, we read midstream's workspace `Cargo.toml` (`vendor/midstream/Cargo.toml:1-99`), the `README.md` and `BENCHMARKS_SUMMARY.md`, and every crate's `lib.rs`:
+
+| Crate | File | LOC | Purpose (from header doc) |
+|---|---|---:|---|
+| `midstreamer-temporal-compare` | `vendor/midstream/crates/temporal-compare/src/lib.rs:1-697` | 697 | DTW, LCS, Levenshtein, generic pattern matching on `Sequence<T>` of `TemporalElement<T>` |
+| `midstreamer-scheduler` | `vendor/midstream/crates/nanosecond-scheduler/src/lib.rs:1-406` | 406 | Priority + deadline-aware task scheduler (RM, EDF, LLF) for low-latency real-time tasks |
+| `midstreamer-attractor` | `vendor/midstream/crates/temporal-attractor-studio/src/lib.rs:1-482` | 482 | Phase-space reconstruction, Lyapunov exponents, attractor classification |
+| `midstreamer-neural-solver` | `vendor/midstream/crates/temporal-neural-solver/src/lib.rs:1-509` | 509 | LTL / CTL / MTL temporal-logic verification with neural reasoning |
+| `midstreamer-strange-loop` | `vendor/midstream/crates/strange-loop/src/lib.rs:1-496` | 496 | Multi-level meta-learning, self-referential systems |
+| `midstreamer-quic` | `vendor/midstream/crates/quic-multistream/src/lib.rs:1-255`, `native.rs:1-303`, `wasm.rs:1-307` | 865 | Thin wrapper over `quinn` (native) and `WebTransport` (WASM); generic QUIC streams |
+
+Plus a TypeScript layer (`vendor/midstream/npm/`, `vendor/midstream/npm-wasm/`) whose product is "real-time LLM streaming" — OpenAI Realtime API client, RTMP / WebRTC / HLS for video, an in-console dashboard, a Whisper transcription scaffold, an MCP server for LLM agents.
+
+The top-level identity is unambiguous: `Cargo.toml:16` describes the package as **`"Real-time LLM streaming with inflight analysis"`**, and the README (`vendor/midstream/README.md:45-80`) frames midstream as a platform that "analyzes [LLM] responses **as they stream in real-time** — enabling instant insights, pattern detection, and intelligent decision-making" — i.e. the streaming domain is **LLM tokens and dashboard telemetry**, not RF signals. A search for any of `csi`, `wifi`, `sensing`, or `sensor` across `vendor/midstream/crates/*/src/*.rs` returns zero hits.
+
+This shapes the conclusion: midstream's *abstractions* (DTW pattern matching, attractor analysis, LTL verification, meta-learning) were chosen for a fundamentally different problem domain than CSI, and its *transport* (QUIC) is a thin `quinn` wrapper rather than a sensing-aware backplane. The candidate seams enumerated above are either already filled by simpler primitives in RuView, or filled better by rvCSI under ADR-097.
+
+### 1.1 What this ADR is *not*
+
+- Not a judgment on midstream's quality. It has 139 passing tests and clean Rust; it is well-engineered for its target domain.
+- Not a decision to drop `vendor/midstream`. The submodule pin is cheap to keep, and the carve-outs in §3 may justify revisiting it.
+- Not a position on the *standalone* midstream product (LLM streaming, OpenAI Realtime, dashboards). That product is unaffected by this ADR.
+
+---
+
+## 2. Decision
+
+**Reject midstream as a system component of RuView.** The four candidate seams are either filled (well) by existing RuView primitives, or are filled by rvCSI's freshly-adopted `EventPipeline` and `RfMemoryStore`. The eight decisions below are the architectural contract.
+
+### D1 — Streaming / pub-sub for the WebSocket fan-out: no change
+
+RuView's sensing-server currently fans out updates to WebSocket clients via `tokio::sync::broadcast::channel::<String>(256)` (`v2/crates/wifi-densepose-sensing-server/src/main.rs:4769`). midstream offers no equivalent in-process broadcast primitive — its TypeScript dashboard fan-out is HTTP-server based (`vendor/midstream/npm/src/dashboard.ts`), and its Rust `midstreamer-quic` crate is a generic point-to-point QUIC wrapper (`vendor/midstream/crates/quic-multistream/src/native.rs:31-69`), not a pub-sub bus.
+
+Tokio's `broadcast` channel is the standard Rust idiom for this pattern, costs effectively nothing per subscriber, integrates with the rest of the Axum + Tokio stack already in use (`v2/crates/wifi-densepose-sensing-server/src/main.rs:36,47`), and is what `rvcsi-runtime` itself uses for event distribution (`vendor/rvcsi/crates/rvcsi-runtime/src/lib.rs`). **Keep `tokio::sync::broadcast`.**
+*Consequences:* zero migration; zero new dependency surface; the WebSocket handlers at `main.rs:1989,2030` continue to work unchanged.
+
+### D2 — CSI → DSP → event pipeline: stay on rvCSI's `EventPipeline`
+
+ADR-097 D2 just adopted `rvcsi-runtime::CaptureRuntime` + `rvcsi_events::EventPipeline` as the CSI ingestion / DSP / event-extraction path. `EventPipeline` is **deterministic, synchronous, single-frame-at-a-time** (`vendor/rvcsi/crates/rvcsi-events/src/pipeline.rs:1-5`: *"Feed it frames with `EventPipeline::process_frame` and drain the tail with `EventPipeline::flush`"*) — and that determinism is load-bearing for ADR-095 D9 (replayability) and ADR-095 D13 (quality scoring against learned baselines).
+
+midstream's stream-processing primitives are designed for the opposite shape: `temporal-attractor-studio` (phase-space reconstruction, Lyapunov exponents) and `temporal-neural-solver` (LTL formula verification) operate on **trajectories** of multi-dimensional states over hundreds-to-thousands of samples (`vendor/midstream/README.md:528-531`: *"Attractor detection: <5ms for 1000-point series"*) — that is closer to RuView's existing RuvSense modules (`v2/crates/wifi-densepose-signal/src/ruvsense/longitudinal.rs`, `intention.rs`) than to anything the runtime DSP layer needs.
+
+Replacing rvCSI's event detectors with midstream constructs would (a) break determinism, (b) re-introduce a parallel CSI-processing implementation — exactly the duplication ADR-097 was opened to remove — and (c) force RuView to invent a `Sequence<T: temporal-compare::TemporalElement>` shim around `CsiFrame` for marginal benefit. **Stay on `rvcsi-events::EventPipeline`.**
+*Consequences:* the determinism / replay guarantees of ADR-095 D9 and ADR-097 D6 remain intact; the work to land `rvcsi-adapter-esp32` (ADR-097 D4, P3) is not duplicated.
+
+### D3 — TDM / multi-source merging: stay on the existing aggregator
+
+The ESP32 mesh's multi-source merging is in `v2/crates/wifi-densepose-hardware/src/aggregator/mod.rs:74-220` — a `UdpSocket`-backed aggregator (`mod.rs:74,85`) that receives parsed `CsiFrame`s from N nodes and forwards them on a `SyncSender<CsiFrame>` to the consumer. The TDM coordination (slot assignment, channel hopping, dwell time) lives in firmware (`firmware/esp32-csi-node/main/`) and is governed by ADR-029 and ADR-073. midstream offers nothing for either side: it has no UDP merger, no slot scheduler, and no firmware-side primitives.
+
+`midstreamer-scheduler` is conceptually adjacent — it does priority + deadline-aware scheduling (`vendor/midstream/crates/nanosecond-scheduler/src/lib.rs:53-63`: `RateMonotonic`, `EarliestDeadlineFirst`, `LeastLaxityFirst`, `FixedPriority`) — but its target is **in-process tokio tasks on a 4-thread executor** (`vendor/midstream/README.md:466-477`: *"4 worker threads"*, *"<50 ns scheduling latency"*), not the cross-device, wall-clock-anchored TDM that RuvSense needs. **Keep the existing `wifi-densepose-hardware` aggregator and firmware-side TDM.**
+*Consequences:* ADR-029 stays as-is; the work to migrate the parser to `rvcsi-adapter-esp32` (ADR-097 D4) is unaffected.
+
+### D4 — UDP receiver backpressure / flow control: existing solutions are correct at each end
+
+There are two distinct backpressure problems in RuView, and neither benefits from midstream:
+
+- **Firmware side (`firmware/esp32-csi-node/main/csi_collector.c:64,223-228`):** lwIP pbuf exhaustion produces `ENOMEM` when the ESP32 tries to UDP-send faster than the network drains. The fix in code is a rate-limit on `stream_sender_send` *inside the CSI callback*. This is a C-level firmware concern with no Rust analogue — midstream cannot run on the ESP32.
+- **Host side (`v2/crates/wifi-densepose-sensing-server/src/main.rs:3638-3640`, `4769`):** `udp_receiver_task` reads from `UdpSocket` and pushes onto `broadcast::channel::<String>(256)`. The bounded channel is itself the backpressure mechanism: lagged subscribers see `RecvError::Lagged`, the buffer wraps, no producer ever blocks. The 256-slot capacity is sized to one second of frame envelopes at the target rate; the per-second packet-yield collapse symptom (`adaptive_controller_decide.c:26-28`) is detected and surfaced by ADR-039 / ADR-081's `pkt_yield_per_sec` accessor, not by transport-layer flow control.
+
+midstream's `quic-multistream` provides per-stream prioritization (`vendor/midstream/crates/quic-multistream/src/native.rs:1-303`), which is a useful flow-control primitive *for QUIC* but not for the UDP-CSI / WS-fan-out topology RuView actually uses. Adopting QUIC end-to-end would mean (a) replacing the ESP32's UDP sender — which would need a QUIC stack on a memory-constrained Xtensa MCU and is out of scope for this project — or (b) terminating QUIC at the aggregator only, which provides no benefit the current bounded `broadcast` channel doesn't. **Keep the existing two-tier backpressure.**
+*Consequences:* the ENOMEM rate-limit at `csi_collector.c:223-228` and the bounded `broadcast::channel::<String>(256)` at `main.rs:4769` continue to be the load-bearing primitives.
+
+### D5 — Carve-out: `temporal-compare` as a future RuvSense-side building block
+
+`midstreamer-temporal-compare` (`vendor/midstream/crates/temporal-compare/src/lib.rs:1-697`) is a clean DTW / LCS / Levenshtein implementation with an LRU cache. RuView's gesture detector at `v2/crates/wifi-densepose-signal/src/ruvsense/gesture.rs` already does DTW template matching, and the longitudinal analysis at `ruvsense/longitudinal.rs` could plausibly benefit from cached pattern matching. If we ever need a *separate* DTW implementation that is decoupled from RuvSense's internal types, `temporal-compare` is a reasonable starting point — but only if and when that need arises.
+
+We **do not adopt it today** because RuvSense's gesture matcher already exists, works, and uses RuView-native types, and pulling in `dashmap`, `lru`, and a generic `TemporalElement<T>` abstraction would be net-negative right now. **Tracked as a future evaluation, not a decision.**
+*Consequences:* zero today; one named option for a future ADR if a "second" DTW pattern appears.
+
+### D6 — Carve-out: `nanosecond-scheduler` for *host-side* edge tier scheduling (future)
+
+If ADR-039's edge-intelligence tier scheduling ever moves from the ESP32 onto a host-side coordinator (e.g. a Raspberry Pi running the cluster aggregator), `nanosecond-scheduler`'s deadline-aware policies (`vendor/midstream/crates/nanosecond-scheduler/src/lib.rs:53-63`) could plausibly host that scheduler. Today the scheduling is firmware-side and the C-level RTOS handles it; there is nothing to schedule in Rust at the granularity midstream offers.
+
+Again: **not a current decision, just an option kept open.**
+*Consequences:* zero today.
+
+### D7 — Submodule disposition: keep `vendor/midstream`
+
+`vendor/midstream` is one git submodule pin; the build does not depend on it; it does not slow down `cargo build --workspace`; and the carve-outs in D5/D6 leave the door open. Removing the submodule would also remove the reference material that justified the carve-outs.
+
+**Keep the submodule, no per-release pin advancement.** Unlike `vendor/rvcsi` (whose pin is bumped per RuView release under ADR-097 D7), `vendor/midstream` has no in-build consumer to validate against. If D5 or D6 ever activates, *that* ADR will start the per-release pin process. Until then the pin can drift freely.
+*Consequences:* one line of `.gitmodules` (`.gitmodules:1-4`) stays; `git submodule update --init` remains a no-op for normal RuView development.
+
+### D8 — Documentation: cross-reference, don't import
+
+The ADR index (`docs/adr/README.md`) gets ADR-098 added under "Architecture and infrastructure". No other docs are updated. The README on the RuView side is untouched; midstream is not part of the RuView platform story.
+*Consequences:* one row added to the ADR index; no churn elsewhere.
+
+---
+
+## 3. Why not adopt (the rejection record)
+
+For institutional memory, the table below records what each midstream crate *would* solve and the alternative RuView already uses. This is the answer to "but we vendored midstream — what is it for?"
+
+| midstream crate | Plausible RuView seam | Already filled by | Verdict |
+|---|---|---|---|
+| `midstreamer-temporal-compare` (DTW, LCS, Levenshtein) | Gesture template matching (`ruvsense/gesture.rs`); longitudinal biomechanics drift | RuvSense's existing DTW gesture matcher | Carve-out only (D5) — not adopted today |
+| `midstreamer-scheduler` (nanosecond priority + deadline) | ESP32 edge-tier scheduling (ADR-039); RuvSense TDM (ADR-029) | Firmware-side RTOS (ESP32); ADR-029's wall-clock-anchored TDM | Carve-out only (D6) — wrong scope today |
+| `midstreamer-attractor` (Lyapunov, phase-space) | RF-field stability detection in `ruvsense/field_model.rs`, `longitudinal.rs` | Welford stats + biomechanics drift (longitudinal.rs); SVD eigenstructure (field_model.rs) | Not adopted — RuvSense's approach is calibrated to RF signal scale and the project's existing dataset, not generic dynamical-systems theory |
+| `midstreamer-neural-solver` (LTL / CTL / MTL verification) | Adversarial signal detection (`ruvsense/adversarial.rs`); coherence-gate decisions | Multi-link consistency checks (adversarial.rs); `coherence_gate.rs` state machine | Not adopted — RuView's adversarial detector is not a formal-verification problem; it's a multi-link physical-consistency check |
+| `midstreamer-strange-loop` (meta-learning, self-modification) | None in RuView's scope | RuView is not a self-modifying learner; AETHER (ADR-024) is contrastive embedding, not meta-learning | Not adopted — out of scope |
+| `midstreamer-quic` (QUIC native + WASM) | Sensing-server → external client transport (alternative to WS) | `tokio::sync::broadcast` + Axum WebSocket + UDP (`main.rs:36-47, 4769, 1989, 2030, 3638`) | Not adopted — see D1, D4 |
+
+The shape of the rejection is consistent: **midstream's abstractions are LLM-token / dashboard-telemetry shaped, RuView's pipeline is RF-frame / event-detector shaped.** Where the two share vocabulary ("streaming", "temporal", "real-time"), the implementations diverge sharply — and the case-by-case analysis above shows that the closer one looks at each seam, the worse the fit gets.
+
+---
+
+## 4. Consequences
+
+**Positive**
+
+- Zero net change to RuView's build, runtime, or surface area; ADR-097's phased rvCSI adoption proceeds unaffected.
+- The decision space around midstream is now bounded and documented; future contributors and AI agents see "ADR-098 already evaluated this; here is why not" before re-opening the question.
+- The two crate-level carve-outs (D5, D6) are explicit, so if the relevant seams appear later, the evaluation can pick up from this ADR rather than start over.
+- `vendor/midstream` (the submodule) remains as reference material, but is correctly marked as not part of the build path.
+
+**Negative / costs**
+
+- One more vendored repo with no in-build consumer — a small but non-zero cognitive load (mitigated by D7's explicit "do not bump the pin").
+- If midstream's published crates evolve materially (e.g. a CSI-aware feature lands), the reasoning in §3 needs revisiting; this is the standard "rejected ADRs go stale" risk and applies to every Rejected ADR in the index.
+
+**Risks**
+
+- The most plausible failure mode of this ADR is *not* "we should have adopted midstream"; it is "we re-open the question in six months without re-reading this ADR." Mitigated by indexing ADR-098 in `docs/adr/README.md` and by the per-crate table in §3 being precise enough to short-circuit the next evaluator.
+
+---
+
+## 5. Alternatives considered
+
+| Alternative | Why not |
+|---|---|
+| **Adopt midstream wholesale as RuView's streaming backbone** | Would force the CSI pipeline into the `Sequence<TemporalElement>` shape (`vendor/midstream/crates/temporal-compare/src/lib.rs:42-70`) and the `quic-multistream` transport (`vendor/midstream/crates/quic-multistream/src/native.rs:1-303`) — both are designed for LLM tokens / arbitrary streams, not validated RF frames with quality scoring. Conflicts directly with ADR-095 D5 (one `CsiFrame` schema), D6 (validate before crossing boundaries), and D9 (deterministic replay). |
+| **Replace `tokio::sync::broadcast` with midstream's QUIC fan-out** | Solves no observed problem. `broadcast::channel::<String>(256)` at `v2/crates/wifi-densepose-sensing-server/src/main.rs:4769` handles N WebSocket subscribers at zero per-subscriber cost; the lagged-subscriber semantics (`RecvError::Lagged`) are exactly what an event-feed wants. QUIC adds TLS + congestion control + per-stream priority — useful for *external* clients across a network, but the sensing-server's clients connect over WS on the same host or LAN. |
+| **Replace `EventPipeline` with `temporal-attractor-studio` / `temporal-neural-solver`** | `EventPipeline` is deterministic by contract (`vendor/rvcsi/crates/rvcsi-events/src/lib.rs:20`) and ADR-097 just made it RuView's event source of truth. Attractor analysis and LTL verification operate on entirely different abstractions; using them as event detectors would re-invent rvCSI's pipeline in a less-determined way. |
+| **Adopt `midstreamer-temporal-compare` for gesture detection now** | RuvSense already has a working DTW gesture matcher tuned to CSI signal scale. Swapping it for a generic `TemporalElement<T>` matcher buys cleanliness but costs a re-tune and a new dep tree (`dashmap`, `lru`). Tracked as D5 for if/when a *second* DTW use case shows up. |
+| **Adopt `midstreamer-scheduler` for the cluster-Pi aggregator** | The cluster aggregator does not currently exist as a real-time scheduler; ADR-039's tier scheduling is firmware-side. Until the host-side schedule appears, importing a deadline-aware scheduler is solution-looking-for-a-problem. Tracked as D6. |
+| **Drop the `vendor/midstream` submodule entirely** | Cheap to keep, useful as the reference material this ADR cites. D7 keeps it on the explicit understanding that the pin is not advanced. |
+
+---
+
+## 6. Open questions / re-evaluation triggers
+
+This ADR is `Rejected` today on the strength of the §1.1 / §3 analysis. The following events would justify re-opening it:
+
+1. **A second DTW / LCS / Levenshtein use case appears in RuView** (e.g. a CLI-side replay diff, a regression test fixture that needs sequence alignment, a TUI for pattern playback). Then re-evaluate `midstreamer-temporal-compare` per D5.
+2. **A host-side real-time scheduler enters RuView's scope** (e.g. the cluster-Pi aggregator becomes responsible for slot timing instead of the ESP32 firmware). Then re-evaluate `midstreamer-scheduler` per D6.
+3. **midstream ships a CSI-aware adapter or RF-scale `Sequence<T>` extension** — i.e. midstream's own scope grows to include sensing primitives. As of the pinned commit (`30fe5eb`), this has not happened (zero matches for `csi|wifi|sensing|sensor` in `vendor/midstream/crates/*/src/*.rs`).
+4. **RuView gains a QUIC-to-external-client requirement** that the WS fan-out cannot service (e.g. a mobile client over a lossy link that benefits from QUIC's stream priority + 0-RTT). Then re-evaluate `midstreamer-quic` per D1 / D4.
+
+If none of these triggers fire, this ADR stays Rejected and the carve-outs (D5, D6) remain optional.

+
+---
+
+## 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.

+# Pi 5 + Hailo Cluster: Building a Cognitive RF Observer with rvcsi
+
+A field-tested tutorial for turning a 4-node Raspberry Pi 5 cluster into a
+multistatic Wi-Fi CSI cognitive RF observer that learns room states,
+predicts the next one, and flags anomalies — entirely from radio.
+
+**Estimated time:** 4–6 hours (hardware 1h, firmware 1h, software 1h, calibration 1–3h)
+
+**What you will build:** A self-learning 4-node cluster that captures Wi-Fi
+Channel State Information from a stable RF beacon, encodes each frame into a
+128-dimensional fingerprint on an on-device Hailo-8 NPU, clusters those
+fingerprints into discrete room states with stable IDs across runs, models
+state transitions with a 2nd-order Markov chain (with measurable predictive
+skill above chance), and persists everything to a queryable brain corpus on
+a workstation. The whole thing runs over Tailscale and is operated through
+a single CLI with **34 subcommands**.
+
+**Who this is for:** RF engineers, smart-home hackers, security researchers,
+and ML/embedded folks comfortable with Linux + systemd. No specific signal-
+processing background required — but you do need patience for hardware
+quirks (nexmon_csi cross-compile is a known dead end; see step 3).
+
+> **The TL;DR**: 4× Pi 5 + 2× Hailo-8 → CSI → 128-d embeddings → cosine
+> k-means with warm-start → 2nd-order Markov → SQLite brain → 34-subcommand
+> operator CLI. Production-grade signal: 39% top-1 ceiling on next-state
+> prediction (16× chance baseline), continuous fleet/drift/anomaly
+> monitoring, and a 12-category time-series corpus.
+
+> **About the name "rvcsi" in this tutorial.** When this tutorial was
+> first written, the cluster's per-Pi capture services were named with
+> an `rvcsi` prefix (`cog-rvcsi-stream`, `cog-rvcsi-correlator`) as
+> branding only — the actual code was Python and didn't depend on the
+> upstream [`ruvnet/rvcsi`](https://github.com/ruvnet/rvcsi) Rust
+> runtime. **As of 2026-05-13**, the v0-appliance project has accepted
+> [ADR-207](https://github.com/ruvnet/v0-appliance/blob/main/docs/adr/ADR-207-rvcsi-library-integration.md)
+> (rvCSI library integration — Option D) and shipped a Rust binary
+> `cog-rvcsi-pi` built on rvcsi-runtime 0.3 that replaces the three
+> Python services. The cutover is per-Pi, operator-driven, with
+> one-command rollback (`scripts/rvcsi-pi/install-rvcsi-pi.sh` and
+> `uninstall-rvcsi-pi.sh`). A given cluster may be running either
+> stack while migration is in progress; the schema and operator
+> surface are unchanged across the cutover. See ADR-207's
+> Implementation log for the current state.

+### Hardware
+
+| Item | Quantity | Approx. cost | Notes |
+|------|----------|--------------|-------|
+| Raspberry Pi 5 (8GB) | 4 | ~$80 each | 4GB works but tight under sustained load |
+| Hailo-8 M.2 HAT (AI Kit) | 2 | ~$110 each | Only 2 needed — encoder is split across cluster-1 + cluster-2 |
+| MicroSD (64GB, A2) | 4 | ~$10 each | A2 class strongly recommended for sustained writes |
+| USB-C PD power supply (27W) | 4 | ~$12 each | Pi 5 draws 5A at full Hailo load |
+| Active cooler | 4 | ~$5 each | Cluster-2 sustains thermal load — passive will throttle |
+| Workstation (≥16GB RAM, Linux) | 1 | — | Hosts the brain HTTP service + clusterer + anomaly daemon |
+| Stable Wi-Fi beacon | 1 | — | Any AP on the same 5 GHz channel. We use ch.149/80MHz. Stability matters more than identity. |
+
+**Total parts cost:** ~$580 plus workstation.
+
+> **Important:** All 4 Pi 5s must use the on-board `bcm43455c0` radio. USB
+> Wi-Fi adapters with otherwise-similar chipsets **will not** work — nexmon's

+
+**Why this split?** Multistatic fusion (combining CSI from 4 spatial vantage
+points into a single weighted observation) is computationally cheap but
+benefits from being on **one** node so the other three only do capture +
+encode. Hailo-8 is the bottleneck cost, so we put two on the cluster
+(one for redundancy, one for the fusion node) and let `cluster-3` + `v0`
+run as pure capture sensors.

+## 3. Per-node firmware: nexmon_csi on Pi 5
+
+**Critical lesson learned (saved you a week):** the workstation x86_64
+cross-compile path for nexmon_csi on Pi 5 **does not work**. The 39-hunk
+patch series applies cleanly on a native Pi 5 ARM build, and fails in
+subtle ways elsewhere.
+
+The recipe that works:
+
+```bash
+# On each Pi 5 (not the workstation):
+sudo apt update && sudo apt install -y \
+    raspberrypi-kernel-headers bc bison flex libssl-dev make \
+    gcc gawk qpdf cmake build-essential libpcap-dev clang gcc-arm-none-eabi
+
+git clone https://github.com/seemoo-lab/nexmon.git ~/nexmon
+cd ~/nexmon
+source setup_env.sh
+make
+
+cd patches
+git clone https://github.com/seemoo-lab/nexmon_csi.git
+cd nexmon_csi
+
+# Apply the Pi-5-friendly patch series — all 39 hunks should apply clean
+# on native ARM. If you see "Hunk #N FAILED", you are almost certainly
+# cross-compiling from x86_64. Stop. Build on the Pi.
+./install.sh
+
+# Switch on:
+sudo mcp                       # 'monitor capability provisioning' — enable
+sudo nexutil -Iwlan0 -s500 -b -l34 -v<86-char base64 capture filter>
+```
+
+> **Pi 5 kernel gotcha:** Pi OS Bookworm ships two kernels — `kernel8.img`
+> (4K pages) and `kernel_2712.img` (16K pages, Pi 5 only). nexmon_csi
+> currently builds clean against `kernel8.img`. Add `kernel=kernel8.img`
+> to `/boot/firmware/config.txt` if you've switched. **After the switch,
+> SSH by hostname via Tailscale** — host keys + DHCP gotchas otherwise.
+
+> **Clock-skew first-boot trap:** Pi 5 has no RTC. First-boot apt will
+> reject "future-dated" `Release` files. Patch your firstboot to wait for
+> `systemd-timesyncd` before running `apt-get`.
+
+The complete commands + full troubleshooting matrix is in the
+[detailed gist](https://gist.github.com/ruvnet/88e7b053c41cb4f4af7a7ec4af873017) — section "Firmware: nexmon_csi on Pi 5".
+
+---
+
+## 4. Per-node services
+
+Each cluster Pi runs a small fixed set of systemd services. Per-host
+topology:
+
+| Service | cluster-1 | cluster-2 | cluster-3 | v0 |
+|---|:--:|:--:|:--:|:--:|
+| `cog-csi-emitter` (raw CSI capture from nexmon) | ✓ | ✓ | ✓ | ✓ |
+| `cog-csi-adapter` (Rust binary; CSI → 256-byte float frames) | ✓ | ✓ | ✓ | ✓ |
+| `cog-rvcsi-stream` (publishes frames to rvcsi-correlator) | ✓ | ✓ | ✓ | ✓ |
+| `cog-hailo-encoder` (frames → 128-d fingerprints on Hailo-8) | ✓ | ✓ | — | — |
+| `cog-rvcsi-correlator` (multistatic fusion across 4 nodes) | — | ✓ | — | — |
+| **Expected service count** | **4** | **5** | **3** | **3** |
+
+The topology is encoded in the workstation's `cog-query fleet-status`
+subcommand, which compares per-host expected services against live
+`systemctl is-active` results. A flat-service check would falsely flag
+cluster-3 and v0 as degraded (they have neither Hailo nor the correlator
+— that's by design).
+
+> **rvcsi cutover (ADR-207 Option D, 2026-05-13).** The three services
+> `cog-csi-emitter`, `cog-csi-adapter`, and `cog-rvcsi-stream` are
+> being consolidated into one Rust binary `cog-rvcsi-pi` built on
+> [rvcsi-runtime](https://crates.io/crates/rvcsi-runtime). The new
+> binary holds the same per-Pi role and the same expected-service
+> count from the operator's view (`fleet-status` already understands
+> both layouts). Deploy with
+> `bash scripts/rvcsi-pi/install-rvcsi-pi.sh <pi-host>`; revert with
+> `scripts/rvcsi-pi/uninstall-rvcsi-pi.sh`. The cutover is per-Pi,
+> not flag-day — mixed Python/Rust clusters are supported. The Hailo
+> encoder + correlator stay Python in this phase; their Rust ports
+> are tracked as follow-on ADRs.
+
+All unit files + the install script are in the
+[detailed gist](https://gist.github.com/ruvnet/88e7b053c41cb4f4af7a7ec4af873017) — section "Per-node systemd units".
+
+---
+
+## 5. Workstation pipeline
+
+The workstation runs ten user-mode units (3 daemons, 7 timers):
+
+| Unit | Type | Cadence | Purpose |
+|---|---|---|---|
+| `cog-rfmem-tail` | daemon | continuous | Ingests live brain entries into the workstation mirror |
+| `cog-rfmem-recall` | daemon | continuous | kNN-matches current fingerprint vs persisted ones, posts `rfmem-recall` |
+| `cog-rfmem-anomaly` | daemon | continuous | 13-axis anomaly detector, posts `rfmem-anomaly` + `rfmem-state-transition` |
+| `cog-rfmem-indexer` | timer | every 5 min | Updates HNSW index for kNN |
+| `cog-rfmem-compress` | timer | hourly | Compresses old brain entries |
+| `cog-rfmem-daily` | timer | nightly 04:00 | Per-day stats roll-up (`rfmem-daily`) |
+| `cog-rfmem-states` | timer | hourly | Re-runs cosine k-means w/ warm-start (`rfmem-state-summary`) |
+| `cog-rfmem-insights` | timer | nightly 04:55 | NL synthesis, posts `rfmem-insights` |
+| `cog-rfmem-drift-check` | timer | nightly 05:00 | Audits cluster file/unit drift, posts `rfmem-drift` |
+| `cog-rfmem-mirror` | timer | hourly | Mirrors cluster-2 brain → workstation read-replica |
+
+Install in one shot:
+
+```bash
+git clone https://github.com/<your-fork>/v0-appliance.git
+cd v0-appliance
+bash scripts/rfmem/install-workstation.sh
+```
+
+The installer is **idempotent** — rerunning is safe and only enables
+units that aren't yet enabled. It also wires a git post-commit hook
+that auto-deploys + auto-smoke-tests on every commit touching
+`scripts/rfmem/`. That closes the "I edited the repo but forgot to
+deploy" gap that bit us repeatedly in early development.
+
+---
+
+## 6. Calibration: getting from raw CSI to room states
+
+This is the longest step but largely passive — let it run.
+
+### 6.1 Walk the room
+
+For 30–60 minutes after the cluster is live, walk through every room you
+want recognized. Sit, stand, move between rooms, repeat. The encoder is
+learning to map "what the room looks like in CSI" into 128-d vectors;
+diversity here matters more than total time.
+
+### 6.2 First clustering pass
+
+```bash
+# Force-trigger the clusterer (it normally fires hourly):
+systemctl --user start cog-rfmem-states.service
+python3 scripts/rfmem/cog-query.py states
+```
+
+Output looks like:
+
+```
+=== rfmem-states — k=16, n=12,847 ===
+  state #0   π=0.184  dwell=42.3s  centroid_drift=0.012  (default)
+  state #1   π=0.121  dwell=18.1s  centroid_drift=0.003
+  state #4   π=0.087  dwell=29.6s  centroid_drift=0.041
+  ...
+```
+
+**Stable IDs across runs.** The warm-start k-means recipe matches new
+centroids to the prior run's centroids by cosine similarity before
+assigning IDs. This means state #4 stays state #4 between hourly runs —
+otherwise downstream Markov transitions would scramble after every
+re-cluster.
+
+### 6.3 Let the Markov chain build
+
+After a few thousand transitions (a few hours of activity), check:
+
+```bash
+python3 scripts/rfmem/cog-query.py prediction-accuracy
+```
+
+You should see something like:
+
+```
+=== prediction-accuracy — training-set top-1 ceilings ===
+  1st-order:  37.1%  (16x chance baseline of 6.25%)
+  2nd-order:  39.4%  (16x chance baseline of 6.25%, 1.06x gain over 1st)
+```
+
+The 2nd-order chain beats 1st-order because it conditions on the
+**previous** state as well as the current one. Self-loops are excluded
+from the argmax (a transition is by definition a state change).
+
+### 6.4 Verify the room learned itself
+
+```bash
+python3 scripts/rfmem/cog-query.py insights
+```
+
+Reads like:
+
+```
+The cluster has observed 446,231 fingerprints, clustering them into
+16 discrete RF states. The room exhibits moderately diverse (stationary
+entropy 0.82/1.0). State #4 is the dominant 'default' state (π=0.214);
+state #13 is the rarest baseline (π=0.018).
+Prediction skill (last hour, 2nd-order): top-1 12.4% (1.98x chance),
+top-3 31.0% (1.65x chance, 412 transitions) (training-set ceiling
+39.4% — operating @ 31% of capacity).
+```
+
+That "operating @ 31% of capacity" line is the operational efficiency:
+how close live performance is to the model's theoretical ceiling. Big
+gap = the room is being noisy in ways the static cluster model doesn't
+capture. Small gap = you're near SOTA for this static model.
+
+---
+
+## 7. Operating the cluster: the cog-query CLI
+
+A single CLI binary with **34 subcommands** + 4 machine-readable JSON
+modes. Practical ones (full list in the gist):
+
+| Subcommand | What it does |
+|---|---|
+| `summary --hours 1` | Bird's-eye view of last hour: anomalies, transitions, recall hits |
+| `top-events --hours 24 --limit 5` | Highest-info events in window (combines novelty + tier + recency) |
+| `top-events --json` | Same, agent-consumable |
+| `insights` | Natural-language synthesis (paragraph) — what the cluster thinks |
+| `insights --json` | Same, structured |
+| `insights --post` | Same, persisted to brain as `rfmem-insights` |
+| `stats` | Corpus: per-category counts, dimensions, vector counts |
+| `motion` | Recent motion events |
+| `anomalies --sort info` | Anomalies sorted by composite info score (1.0–8.0) |
+| `circadian` | 24-hour bin of activity — does the room have a daily rhythm? |
+| `by-state` | Per-state metrics (dwell, σ-baseline, novelty distribution) |
+| `markov` | Top transitions by frequency, both 1st + 2nd-order |
+| `transitions --sort novelty` | Rare/surprising transitions |
+| `dwell-times` | How long the room stays in each state |
+| `prediction-accuracy` | 1st + 2nd-order top-1 ceilings |
+| `baseline-drift` | Has the noise floor shifted? (slow change) |
+| `centroid-drift` | Has any state's RF signature materially changed? |
+| `fleet-status` | Per-host expected-service liveness check |
+| `fleet-status --json` | Same, agent-consumable |
+| `fleet-status --post` | Same, persisted to brain as `rfmem-fleet` (heartbeat) |
+| `check-drift` | Workstation/cluster file + unit drift audit |
+| `replica-status` | Hourly cluster-2 → workstation mirror health |
+
+### The fleet-health triad
+
+Three subcommands cover the operator's full health picture:
+
+- `check-drift` — file content drift (what's deployed vs what's in git)
+- `replica-status` — workstation mirror lag (last successful sync)
+- `fleet-status` — service liveness across the 4 Pis (topology-aware)
+
+If all three are green, the cluster is healthy. If any one fires, you
+have a concrete starting point.
+
+---
+
+## 8. What you can measure
+
+After a week of runtime, you can answer questions like:
+
+- **"What's the room's most common 'baseline' state?"** → `states` shows
+  the π-dominant cluster ID.
+- **"Did anything weird happen last night?"** → `anomalies --sort info
+  --hours 12` sorts by combined-information score (novelty × tier × state-
+  rarity × calmness).
+- **"How predictable is the room?"** → `insights` reports stationary
+  entropy (0.0 = single state, 1.0 = uniform). Most rooms land 0.6–0.9.
+- **"What's the most novel transition ever observed?"** → `transitions
+  --sort novelty --limit 1`. We've seen transitions with
+  `transition_p=0.0000` — never observed before in 446k+ embeddings.
+- **"Is the room changing slowly?"** → `centroid-drift` flags states
+  whose 128-d signature has moved > 0.05 cosine distance since the prior
+  clusterer run. Common cause: a piece of furniture moved.
+- **"What's the daily rhythm?"** → `circadian` bins activity by hour.
+  Most rooms show clear morning/evening peaks.
+
+---
+
+## 9. Troubleshooting
+
+| Symptom | Likely cause | Fix |
+|---|---|---|
+| `nexmon_csi` build fails with FAILED hunks | Cross-compiling from x86_64 | Build on the Pi natively |
+| Pi 5 stops booting after kernel switch | Wrong `kernel=` in `/boot/firmware/config.txt` | Use `kernel=kernel8.img` |
+| First boot fails on `apt update` | No RTC → clock skew, apt rejects "future-dated" Release files | Wait for `systemd-timesyncd` in firstboot |
+| `cog-rfmem-now` times out | Workstation daemon swap-thrashing | Bump `MemoryMax=` in unit file (we run 1G) |
+| `fleet-status` shows DEGRADED on cluster-3 / v0 | Topology unaware (old version) | Update to latest — per-host expected-services |
+| Cluster-2 Hailo encoder silent | `cp -r` made encoder a directory, not a file | `install -m 0755` instead |
+| 2nd-order Markov top-1 = 0% | Self-loop dominates argmax | Zero out self-loop before `.argmax()` |
+| State IDs change between runs | No warm-start k-means | Update clusterer to match new centroids to prior run by cosine |
+| HardFaults during embedded N6 bring-up | (Different topic, see [ADR-027](../adr/) for STM32N6 startup notes) | — |
+
+---
+
+## 10. Next steps
+
+Once your cluster is producing stable predictions and clean fleet health,
+the natural directions are:
+
+1. **Cross-room correlation** — train a second cluster in another room
+   and feed both into the workstation. The brain already supports
+   multiple namespaces.
+2. **Active sensing** — instead of passively observing whatever beacon is
+   present, drive your own (e.g., dedicated 5 GHz beacon AP at fixed
+   power). Eliminates upstream variability.
+3. **Vital signs** — the RuView project has companion code for extracting
+   heart-rate and breathing from CSI; the 128-d encoder output is a
+   reasonable input feature.
+4. **Federated training** — multiple physical sites publishing to a shared
+   brain. Each site keeps its own clusters; transitions are the shared
+   vocabulary.
+5. **Push to upstream RuView** — if your cluster develops capabilities not
+   in this tutorial (you'll know by the time you've written the README),
+   send a PR.

+
+If a standalone `aggregator` command prints live packets, the ESP32 fleet is already reaching that host. To visualize the same data, stop the standalone aggregator and run `sensing-server` on that same host and UDP port. The sensing server is the aggregator used by the REST API, WebSocket stream, dashboard, and Observatory.

+
+## Mixamo X Bot
+
+Demos 04 and 05 expect `assets/X Bot.fbx`. It's gitignored (size + license
+boundary). Download yours from [mixamo.com](https://mixamo.com): pick the
+"X Bot" character, export as **FBX Binary**, **T-Pose**, **Without Skin**,
+and drop it into `assets/`.
+
+## Live ESP32 CSI overlay (demo 05 only)
+
+`server/ruvultra-csi-bridge.py` is the systemd-deployable bridge that runs on
+the `ruvultra` host (over Tailscale). It listens for ESP32-S3 CSI on UDP and
+re-broadcasts it as WebSocket frames at `ws://ruvultra:8766/csi`. Demo 05
+auto-connects; if the socket is down, it falls back to the bundled idle clip
+plus a synthetic CSI driver.
+
+## Open issues
+
+- [#583](https://github.com/ruvnet/RuView/issues/583) — head/face tracking
+  fidelity in `05-skinned-realtime.html`. Recommended fix: swap MediaPipe
+  Pose Heavy for MediaPipe Holistic (same API, adds 468-point face mesh +
+  hand landmarks for proper PnP head pose and finger curl tracking).

This is a **slot-capacity heuristic**, not a learned counter — the reported count tracks subcarrier diversity, not actual occupancy.

 - **Vitals packet** -- 32-byte UDP packet at 1 Hz (magic `0xC5110002`)

+### What this firmware does NOT do (Tier 2 caveats)
+
+- It does **not** run a trained neural model. The "person count" is an
+  arithmetic slot-capacity heuristic over the top-K subcarrier groups
+  (`firmware/esp32-csi-node/main/edge_processing.c:481`). It tracks
+  subcarrier diversity, not actual occupancy.
+- It does **not** run pose estimation. Pose-related features in the host
+  UI come from the Rust `wifi-densepose-sensing-server` running a separate
+  pipeline. When no `.rvf` model file is loaded via `--model`, the server
+  drives the on-screen skeleton from signal-based heuristics (amplitude
+  variance, motion-band power), not from learned keypoint inference. The
+  repository does not ship pre-trained weights — see issues
+  [#509](../../issues/509) and [#506](../../issues/506) for context, and
+  [ADR-079](../../docs/adr/ADR-079-camera-supervised-pose-finetune.md) for
+  the planned training path (phases P7-P9 are `Pending`).
+- The presence indicator is a calibrated variance threshold and **will
+  false-positive** under strong RF interference from non-human sources
+  (fans near the antenna, microwave duty cycles, neighbouring AP power
+  swings) without re-running the 60-second ambient calibration. If you
+  see ghost detections, re-calibrate by power-cycling in an empty room.

+UDP relay for Docker Desktop on Windows (issue #374, #386).

+Docker Desktop on Windows multiplexes inbound UDP from multiple source IPs to
+a single source IP inside the container, which causes packets from all but one

+(the relay's loopback socket), Docker passes them all through.

- * 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
- *
- * Format (2) — nexmon_csi UDP payload header (all little-endian):
- *   off  size  field
- *     0     2  magic            = 0x1111
- *     2     1  rssi             int8 (dBm)
- *     3     1  fctl             uint8 (802.11 frame-control byte)
- *     4     6  src_mac          uint8[6]
- *    10     2  seq_cnt          uint16 (802.11 sequence-control)
- *    12     2  core_stream      uint16 (bits[2:0]=rx core, bits[5:3]=spatial stream)
- *    14     2  chanspec         uint16 (Broadcom d11ac chanspec)

- *    18   ...  CSI: nsub complex samples; for RVCSI_NX_CSI_FMT_INT16_IQ that is
- *               4*nsub bytes = nsub pairs of int16 LE (real, imag), raw counts.

-//! # 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.
