fix(firmware): v0.6.4-esp32 — Tmr Svc 16 KiB stack + version drift fix (#505 )

Two bugs in the v0.6.3-esp32 release, both reported in #505: 1. **4 MB binary boot-loops with Tmr Svc stack overflow.** The adaptive_controller fast loop runs emit_feature_state() (lwIP sendto via stream_sender) AND apply_decision() (which can call rv_mesh_send_anomaly — another sendto) inside the FreeRTOS Timer Svc callback. The previous fix (a426ae386) bumped from the 2 KiB IDF default to 8 KiB; that absorbs the steady-state fast tick but not the worst case where a state transition fires the anomaly emit on top of an already-stacked feature_state emit. Bump to 16 KiB across both sdkconfig.defaults.template (8 MB build) and sdkconfig.defaults.4mb so the two release variants stay in sync. 2. **All v0.6.3 binaries reported `App version: 0.6.2`.** version.txt was never bumped at the v0.6.3-esp32 tag. CMake reads version.txt into project(VERSION ...) which feeds esp_app_get_description()-> version. Bump to 0.6.4 to match the new release tag. Verified on ESP32-S3 (COM8, MAC d0:cf:13:44:01:84): - 4 MB build flashed clean, 853 KiB binary, 54 % flash free - Boot banner now reports `App version: 0.6.4` - 70 s soak, 71 medium ticks, 0 stack overflow, 0 reboots - 5 Hz feature_state emit confirmed (seq=299 at ~60 s) - CSI capture active throughout (motion=1.00, presence=4-20) Closes #505.

+
+          ## Modes
+
+          - Default — synthetic in-browser demo (no backend, no network calls).
+          - `?backend=auto` — fetch from `/api/splats` on the same origin
+            (only works when the viewer is served by `ruview-pointcloud serve`).
+          - `?backend=<url>` — fetch from `<url>/api/splats`. The intended
+            local-ESP32 use is `?backend=http://127.0.0.1:9880`: run
+            `ruview-pointcloud serve --bind 127.0.0.1:9880` on the same
+            machine with your ESP32 streaming CSI to UDP port 3333, then
+            visit the URL above. The local server's CorsLayer permits
+            requests from `https://ruvnet.github.io`, and modern browsers
+            permit HTTPS→127.0.0.1 mixed-content as a trustworthy origin.
+            The "📡 Connect ESP32" button in the viewer prompts for this
+            URL and persists it in localStorage.
+          - `?live=1` — require a live backend; show an offline message instead
+            of falling back to the synthetic demo.
+
+          See ADR-094 for the deployment design.

+## [Unreleased]
+
+### Added
+- **`nvsim` crate — deterministic NV-diamond magnetometer pipeline simulator** (ADR-089) —
+  New standalone leaf crate at `v2/crates/nvsim` modeling a forward-only
+  magnetic sensing path: scene → source synthesis (Biot–Savart, dipole,
+  current loop, ferrous induced moment) → material attenuation
+  (Air/Drywall/Brick/Concrete/Reinforced/SteelSheet) → NV ensemble
+  (4 〈111〉 axes, ODMR linear-readout proxy, shot-noise floor per
+  Wolf 2015 / Barry 2020) → 16-bit ADC + lock-in demodulation →
+  fixed-layout `MagFrame` records → SHA-256 witness. Six-pass build
+  per `docs/research/quantum-sensing/15-nvsim-implementation-plan.md`.
+  50 tests, ~4.5 M samples/s on x86_64 (4500× the Cortex-A53 1 kHz
+  acceptance gate), pinned reference witness
+  `cc8de9b01b0ff5bd97a6c17848a3f156c174ea7589d0888164a441584ec593b4`
+  for byte-equivalence regression. WASM-ready by construction
+  (zero `std::time/fs/env/process/thread`); builds cleanly for
+  `wasm32-unknown-unknown`. ADR-090 (Proposed, conditional) tracks the
+  optional Lindblad/Hamiltonian extension if AC magnetometry, MW power
+  saturation, hyperfine spectroscopy, or pulsed protocols become required.
+
+### Fixed
+- **Ghost skeletons in live UI with multi-node ESP32 setups** (#420, ADR-082) —
+  `tracker_bridge::tracker_to_person_detections` documented itself as filtering
+  to `is_alive()` tracks but in fact passed every non-Terminated track to the
+  WebSocket stream. `Lost` tracks — kept inside `reid_window` for
+  re-identification but not currently observed — were rendering as phantom
+  skeletons, accumulating to 22-24 with 3 nodes × 10 Hz CSI while
+  `estimated_persons` correctly reported 1. Added
+  `PoseTracker::confirmed_tracks()` (Tentative + Active only) and rewired the
+  bridge to use it. Lost tracks remain in the tracker for re-ID; they just
+  no longer ship to the UI. Regression test:
+  `test_lost_tracks_excluded_from_bridge_output`.
+- **Rust workspace build with `--no-default-features` on Windows** (#366, #415) —
+  `wifi-densepose-mat`, `wifi-densepose-sensing-server`, and `wifi-densepose-train`
+  all depended on `wifi-densepose-signal` with default features enabled, which
+  pulled `ndarray-linalg` → `openblas-src` → vcpkg/system-BLAS through the entire
+  workspace. `--no-default-features` at the workspace root then could not opt out
+  of BLAS, breaking `cargo build` / `cargo test` on Windows without vcpkg. All
+  three consumers now declare `wifi-densepose-signal = { ..., default-features = false }`,
+  so `cargo test --workspace --no-default-features` builds cleanly without
+  vcpkg/openblas. Validated: 1,538 tests pass, 0 fail, 8 ignored.
+- **`signal` test `test_estimate_occupancy_noise_only` failed without `eigenvalue`** —
+  The test unwrapped the `NotCalibrated` stub returned when the BLAS-backed
+  `estimate_occupancy` is compiled out. Gated with `#[cfg(feature = "eigenvalue")]`
+  so it only runs when the real implementation is available.
+
+## [v0.6.2-esp32] — 2026-04-20
+
+Firmware release cutting ADR-081 and the Timer Svc stack fix discovered during
+on-hardware validation. Cut from `main` at commit pointing to this entry.
+Tested on ESP32-S3 (QFN56 rev v0.2, MAC `3c:0f:02:e9:b5:f8`), 30 s continuous
+run: no crashes, 149 `rv_feature_state_t` emissions (~5 Hz), medium/slow ticks
+firing cleanly, HEALTH mesh packets sent.
+
+### Fixed
+- **Firmware: Timer Svc stack overflow on ADR-081 fast loop** — `emit_feature_state()` runs inside the FreeRTOS Timer Svc task via the fast-loop callback; it calls `stream_sender` network I/O which pushes past the ESP-IDF 2 KiB default timer stack and panics ~1 s after boot. Bumped `CONFIG_FREERTOS_TIMER_TASK_STACK_DEPTH` to 8 KiB in `sdkconfig.defaults`, `sdkconfig.defaults.template`, and `sdkconfig.defaults.4mb`. Follow-up (tracked separately): move heavy work out of the timer daemon into a dedicated worker task.
+- **Firmware: `adaptive_controller.c` implicit declaration** (#404) — `fast_loop_cb` called `emit_feature_state()` before its static definition, triggering `-Werror=implicit-function-declaration`. Added a forward declaration above the first use.
+
+### Changed
+- **CI: firmware build matrix (8MB + 4MB)** — `firmware-ci.yml` now matrix-builds both the default 8MB (`sdkconfig.defaults`) and 4MB SuperMini (`sdkconfig.defaults.4mb`) variants, uploading distinct artifacts and producing variant-named release binaries (`esp32-csi-node.bin` / `esp32-csi-node-4mb.bin`, `partition-table.bin` / `partition-table-4mb.bin`).
+
+### Added
+- **ADR-081: Adaptive CSI Mesh Firmware Kernel** — New 5-layer architecture
+  (Radio Abstraction Layer / Adaptive Controller / Mesh Sensing Plane /
+  On-device Feature Extraction / Rust handoff) that reframes the existing
+  ESP32 firmware modules as components of a chipset-agnostic kernel. ADR
+  in `docs/adr/ADR-081-adaptive-csi-mesh-firmware-kernel.md`. Goal: swap
+  one radio family for another without changing the Rust signal /
+  ruvector / train / mat crates.
+- **Firmware: radio abstraction vtable (`rv_radio_ops_t`)** — New
+  `firmware/esp32-csi-node/main/rv_radio_ops.{h}` defines the
+  chipset-agnostic ops (init, set_channel, set_mode, set_csi_enabled,
+  set_capture_profile, get_health), profile enum
+  (`RV_PROFILE_PASSIVE_LOW_RATE` / `ACTIVE_PROBE` / `RESP_HIGH_SENS` /
+  `FAST_MOTION` / `CALIBRATION`), and health snapshot struct.
+  `rv_radio_ops_esp32.c` provides the ESP32 binding wrapping
+  `csi_collector` + `esp_wifi_*`. A second binding (mock or alternate
+  chipset) is the portability acceptance test for ADR-081.
+- **Firmware: `rv_feature_state_t` packet (magic `0xC5110006`)** — New
+  60-byte compact per-node sensing state (packed, verified by
+  `_Static_assert`) in `firmware/esp32-csi-node/main/rv_feature_state.h`:
+  motion, presence, respiration BPM/conf, heartbeat BPM/conf, anomaly
+  score, env-shift score, node coherence, quality flags, IEEE CRC32.
+  Replaces raw ADR-018 CSI as the default upstream stream (~99.7%
+  bandwidth reduction: 300 B/s at 5 Hz vs. ~100 KB/s raw).
+- **Firmware: mock radio ops binding for QEMU** — New
+  `firmware/esp32-csi-node/main/rv_radio_ops_mock.c`, compiled only when
+  `CONFIG_CSI_MOCK_ENABLED`. Satisfies ADR-081's portability acceptance
+  test: a second `rv_radio_ops_t` binding compiles and runs against the
+  same controller + mesh-plane code as the ESP32 binding.
+- **Firmware: feature-state emitter wired into controller fast loop** —
+  `adaptive_controller.c` now emits one 60-byte `rv_feature_state_t` per
+  fast tick (default 200 ms → 5 Hz), pulling from the latest edge vitals
+  and controller observation. This is the first end-to-end Layer 4/5
+  path for ADR-081.
+- **Firmware: `csi_collector_get_pkt_yield_per_sec()` /
+  `_get_send_fail_count()` accessors** — Expose the CSI callback rate
+  and UDP send-failure counter so the ESP32 radio ops binding can
+  populate `rv_radio_health_t.pkt_yield_per_sec` and `.send_fail_count`,
+  closing the adaptive controller's observation loop.
+- **Firmware: host-side unit test suite for ADR-081 pure logic** — New
+  `firmware/esp32-csi-node/tests/host/` (Makefile + 2 test files + shim
+  `esp_err.h`). Exercises `adaptive_controller_decide()` (9 test cases:
+  degraded gate on pkt-yield collapse + coherence loss, anomaly > motion,
+  motion → SENSE_ACTIVE, aggressive cadence, stable presence →
+  RESP_HIGH_SENS, empty-room default, hysteresis, NULL safety) and
+  `rv_feature_state_*` helpers (size assertion, IEEE CRC32 known
+  vectors, determinism, receiver-side verification). 33/33 assertions
+  pass. Benchmarks: decide() 3.2 ns/call, CRC32(56 B) 614 ns/pkt
+  (87 MB/s), full finalize() 616 ns/call. Pure function
+  `adaptive_controller_decide()` extracted to
+  `adaptive_controller_decide.c` so the firmware build and the host
+  tests share a single source-of-truth implementation.
+- **Scripts: `validate_qemu_output.py` ADR-081 checks** — Validator
+  (invoked by ADR-061 `scripts/qemu-esp32s3-test.sh` in CI) gains three
+  checks for adaptive controller boot line, mock radio ops
+  registration, and slow-loop heartbeat, so QEMU runs regression-gate
+  Layer 1/2 presence.
+- **Firmware: ADR-081 Layer 3 mesh sensing plane** — New
+  `firmware/esp32-csi-node/main/rv_mesh.{h,c}` defines 4 node roles
+  (Anchor / Observer / Fusion relay / Coordinator), 7 on-wire message
+  types (TIME_SYNC, ROLE_ASSIGN, CHANNEL_PLAN, CALIBRATION_START,
+  FEATURE_DELTA, HEALTH, ANOMALY_ALERT), 3 authorization classes
+  (None / HMAC-SHA256-session / Ed25519-batch), `rv_node_status_t`
+  (28 B), `rv_anomaly_alert_t` (28 B), `rv_time_sync_t`,
+  `rv_role_assign_t`, `rv_channel_plan_t`, `rv_calibration_start_t`.
+  Pure-C encoder/decoder (`rv_mesh_encode()` / `rv_mesh_decode()`) with
+  16-byte envelope + payload + IEEE CRC32 trailer; convenience encoders
+  for each message type. Controller now emits `HEALTH` every slow-loop
+  tick (30 s default) and `ANOMALY_ALERT` on state transitions to ALERT
+  or DEGRADED. Host tests: `test_rv_mesh` exercises 27 assertions
+  covering roundtrip, bad magic, truncation, CRC flipping, oversize
+  payload rejection, and encode+decode throughput (1.0 μs/roundtrip
+  on host).
+- **Rust: ADR-081 Layer 1/3 mirror module** — New
+  `crates/wifi-densepose-hardware/src/radio_ops.rs` mirrors the
+  firmware-side `rv_radio_ops_t` vtable as the Rust `RadioOps` trait
+  (init, set_channel, set_mode, set_csi_enabled, set_capture_profile,
+  get_health) and provides `MockRadio` for offline testing.
+  Also mirrors the `rv_mesh.h` types (`MeshHeader`, `NodeStatus`,
+  `AnomalyAlert`, `MeshRole`, `MeshMsgType`, `AuthClass`) and ships
+  byte-identical `crc32_ieee()`, `decode_mesh()`, `decode_node_status()`,
+  `decode_anomaly_alert()`, and `encode_health()`. Exported from
+  `lib.rs`. 8 unit tests pass; `crc32_matches_firmware_vectors`
+  verifies parity with the firmware-side test vectors
+  (`0xCBF43926` for `"123456789"`, `0xD202EF8D` for single-byte zero),
+  and `mesh_constants_match_firmware` asserts `MESH_MAGIC`,
+  `MESH_VERSION`, `MESH_HEADER_SIZE`, and `MESH_MAX_PAYLOAD` match
+  `rv_mesh.h` byte-for-byte. Satisfies ADR-081's portability
+  acceptance test: signal/ruvector/train/mat crates are untouched.
+- **Firmware: adaptive controller** — New
+  `firmware/esp32-csi-node/main/adaptive_controller.{c,h}` implements
+  the three-loop closed-loop control specified by ADR-081: fast
+  (~200 ms) for cadence and active probing, medium (~1 s) for channel
+  selection and role transitions, slow (~30 s) for baseline
+  recalibration. Pure `adaptive_controller_decide()` policy function is
+  exposed in the header for offline unit testing. Default policy is
+  conservative (`enable_channel_switch` and `enable_role_change` off);
+  Kconfig surface added under "Adaptive Controller (ADR-081)".
+
+### Fixed
+- **Firmware: SPI flash cache crash under high CSI callback pressure** (RuView#396, #397) — ESP32-S3 nodes crashed in `cache_ll_l1_resume_icache` / `wDev_ProcessFiq` after ~2400 callbacks when the promiscuous filter admitted DATA frames at 100–500 Hz. Fixed by narrowing the filter mask to `WIFI_PROMIS_FILTER_MASK_MGMT` (~10 Hz beacons), adding a 50 Hz early callback rate gate (`CSI_MIN_PROCESS_INTERVAL_US`) that drops excess callbacks before any processing work, and enabling `CONFIG_ESP_WIFI_EXTRA_IRAM_OPT=y` as defense-in-depth. Stability validated with a 4-min-per-node soak.
+- **Firmware: `filter_mac` / `node_id` clobber by WiFi driver init** (#232, #375, #385, #386, #390, #397) — `g_nvs_config` can be corrupted during `wifi_init_sta()` on some devices (confirmed on `80:b5:4e:c1:be:b8`), reverting `node_id` to the Kconfig default and producing garbage MAC-filter reads in the CSI callback (100–500 Hz). New `csi_collector_set_node_id()` API called from `app_main()` **before** `wifi_init_sta()` captures both fields into module-local statics (`s_node_id`, `s_filter_mac`, `s_filter_mac_set`). `csi_collector_init()` now runs a canary that distinguishes "early≠g_nvs_config" (corruption confirmed) from a no-op match. All CSI runtime paths use the defensive copies exclusively.
+- **Firmware: `edge_processing` sample rate mismatch** (#397) — `estimate_bpm_zero_crossing()` was called with a hard-coded `sample_rate = 20.0f`, but MGMT-only promiscuous delivers ~10 Hz. Breathing and heart-rate reports were 2× too high. Corrected to `10.0f` with an explicit comment tying it to the callback rate.
+- **`provision.py` esptool command form** (#391, #397) — ESP-IDF v5.4 bundles `esptool 4.10.0`, which only accepts `write_flash` (underscore). Standalone `pip install esptool` v5.x accepts both forms but prefers `write-flash`. #391 switched to `write-flash` which broke the documented ESP-IDF Python venv flow; #397 reverts to `write_flash` (works with both esptool 4.x and 5.x) with an inline comment warning future maintainers not to "re-fix" it.
+- **`provision.py` esptool v5 dry-run hint** (#391) — Stale `write_flash` (underscore) syntax in the dry-run manual-flash hint now uses `write-flash` (hyphenated) for esptool >= 5.x. The primary flash command was already correct.
+- **`provision.py` silent NVS wipe** (#391) — The script replaces the entire `csi_cfg` NVS namespace on every run, so partial invocations were silently erasing WiFi credentials and causing `Retrying WiFi connection (10/10)` in the field. Now refuses to run without `--ssid`, `--password`, and `--target-ip` unless `--force-partial` is passed. `--force-partial` prints a warning listing which keys will be wiped.
+- **Firmware: defensive `node_id` capture** (#232, #375, #385, #386, #390) — Users on multi-node deployments reported `node_id` reverting to the Kconfig default (`1`) in UDP frames and in the `csi_collector` init log, despite NVS loading the correct value. The root cause (memory corruption of `g_nvs_config`) has not been definitively isolated, but the UDP frame header is now tamper-proof: `csi_collector_init()` captures `g_nvs_config.node_id` into a module-local `s_node_id` once, and `csi_serialize_frame()` plus all other consumers (`edge_processing.c`, `wasm_runtime.c`, `display_ui.c`, `swarm_bridge_init`) read it via the new `csi_collector_get_node_id()` accessor. A canary logs `WARN` if `g_nvs_config.node_id` diverges from `s_node_id` at end-of-init, helping isolate the upstream corruption path. Validated on attached ESP32-S3 (COM8): NVS `node_id=2` propagates through boot log, capture log, init log, and byte[4] of every UDP frame.

+- **Client-side lerp smoothing** — UI keypoints interpolate between frames (alpha=0.15) for fluid skeleton movement.
+- **Multi-node mesh tests** — 8 integration tests covering 1-255 node configurations.
+- **`wifi_densepose` Python package** — `from wifi_densepose import WiFiDensePose` now works (#314).
+
+### Fixed
+- **Watchdog crash on busy LANs (#321)** — Batch-limited edge_dsp to 4 frames before 20ms yield. Fixed idle-path busy-spin (`pdMS_TO_TICKS(5)==0`).
+- **No detection from edge vitals (#323)** — Server now generates `sensing_update` from Tier 2+ vitals packets.
+- **RSSI byte offset mismatch (#332)** — Server parsed RSSI from wrong byte (was reading sequence counter).
+- **Stack overflow risk** — Moved 4KB of BPM scratch buffers from stack to static storage.
+- **Stale node memory leak** — `node_states` HashMap evicts nodes inactive >60s.
+- **Unsafe raw pointer removed** — Replaced with safe `.clone()` for adaptive model borrow.
+- **Firmware CI** — Upgraded to IDF v5.4, replaced `xxd` with `od` (#327).
+- **Person count double-counting** — Multi-node aggregation changed from `sum` to `max`.
+- **Skeleton jitter** — Removed tick-based noise, dampened procedural animation, recalibrated feature scaling for real ESP32 data.
+
+### Changed
+- Motion-responsive skeleton: arm swing (0-80px) driven by CSI variance, leg kick (0-50px) by motion_band_power, vertical bob when walking.
+- Person count thresholds recalibrated for real ESP32 hardware (1→2 at 0.70, EMA alpha 0.04).
+- Vital sign filtering: larger median window (31), faster EMA (0.05), looser HR jump filter (15 BPM).
+- Vendored ruvector updated to v2.1.0-40 (316 commits ahead).

+# Archive
+
+Frozen, no-longer-active components of RuView preserved for historical
+reference, reproducibility, and load-bearing legacy paths the active
+codebase still depends on.
+
+## What lives here
+
+| Path | What it is | Why it's archived | Still load-bearing? |
+|------|------------|-------------------|---------------------|
+| `v1/` | Original Python implementation of RuView (CSI processing, hardware adapters, services, FastAPI) | Superseded by the Rust workspace at `v2/`; ~810× slower in benchmarks. Kept rather than deleted because the deterministic proof bundle (`v1/data/proof/`) is part of the pre-merge witness verification process per ADR-011 / ADR-028. | **Yes — for the proof bundle only.** Active code lives in `v2/`. |
+
+## What "archived" means
+
+- **Do not add new features here.** New work goes in `v2/`.
+- **Do not refactor or modernize the archived code beyond what is
+  strictly necessary** to keep the load-bearing paths working. The
+  Python proof bundle is intentionally frozen so that its SHA-256
+  reproducibility holds across releases (per ADR-028's witness
+  verification requirement).
+- **Bug fixes inside archived code are allowed** when the bug affects a
+  still-load-bearing path (currently: only the Python proof). All
+  other "bugs" in archived code are out-of-scope — they are part of
+  the historical record and any fix would unnecessarily churn the
+  witness hashes.
+- **CI continues to verify the load-bearing paths.**
+  `.github/workflows/verify-pipeline.yml` runs the Python proof on
+  every push and PR; if you change anything inside `archive/v1/src/`
+  or `archive/v1/data/proof/`, expect the determinism check to flag
+  it.
+
+## Quick reference for the load-bearing paths
+
+```bash
+# Run the deterministic Python proof (must print VERDICT: PASS)
+python archive/v1/data/proof/verify.py
+
+# Regenerate the expected hash (only if numpy/scipy version legitimately changed)
+python archive/v1/data/proof/verify.py --generate-hash
+
+# Run the full Python test suite (legacy, still maintained)
+cd archive/v1&& python -m pytest tests/ -x -q
+```
+
+## Why we keep `v1/` rather than delete it
+
+1. **Trust kill-switch.** The proof at `v1/data/proof/verify.py` feeds
+   a known reference signal through the full pipeline and hashes the
+   output. If the active code's behavior drifts, the hash changes and
+   CI fails. This is what stops accidental regression in the science
+   layer of the codebase.
+
+2. **Witness verification.** ADR-028's witness-bundle process bundles
+   the proof, the rust workspace test results, and firmware hashes
+   into a tarball recipients can self-verify. Removing v1 would break
+   that chain.
+
+3. **Historical reference.** ADR-011 documents the "no mocks in
+   production code" decision; the original violations and their fixes
+   live in this Python codebase. The ADRs reference these paths.
+
+If the time comes to retire the proof bundle (e.g., a Rust port of
+the proof exists and the Python version is no longer canonical), the
+right move is a single follow-up that simultaneously: ports the
+witness-bundle process, updates `verify-pipeline.yml`, and either
+deletes `archive/v1/` or moves it to a separate read-only repository.
+That decision belongs in its own ADR.
