fix(esp32): use runtime node_id from NVS in outgoing packets - #232

Users on multi-node ESP32 deployments have been reporting for months
that their provisioned `node_id` reverts to the Kconfig default of `1`
in UDP frames and the `csi_collector` init log, despite boot showing:

    nvs_config: NVS override: node_id=4
    main: ESP32-S3 CSI Node (ADR-018) - Node ID: 4
    csi_collector: CSI collection initialized (node_id=1, channel=11)

See #232, #375, #385, #386, #390. The root memory-corruption path for
the `g_nvs_config.node_id` byte has not been definitively isolated
(does not reproduce on my attached ESP32-S3 running current source
and the v0.6.0 release binary), but the UDP frame header can be made
tamper-proof regardless:

1. `csi_collector_init()` now captures `g_nvs_config.node_id` into a
   module-local `static uint8_t s_node_id` at init time.
2. `csi_serialize_frame()` reads `buf[4]` from `s_node_id`, not from
   the global - so any later corruption of `g_nvs_config` cannot
   affect outgoing CSI frames.
3. All other consumers (`edge_processing.c` x3, `wasm_runtime.c`,
   `display_ui.c`, `main.c swarm_bridge_init`) now go through a new
   `csi_collector_get_node_id()` accessor instead of reading the
   global directly.
4. A canary at end-of-init logs `WARN` if `g_nvs_config.node_id`
   already diverges from the captured value - this will pinpoint
   the corruption path if it happens on a user's device.

Hardware validation on attached ESP32-S3 (COM8):
  - NVS loads node_id=2
  - Boot log: `main: ... Node ID: 2`
  - NEW log: `csi_collector: Captured node_id=2 at init (defensive
    copy for #232/#375/#385/#390)`
  - Init log: `csi_collector: CSI collection initialized (node_id=2)`
  - UDP frame byte[4] = 2 (verified via socket sniffer, 15/15 packets)

This is defense in depth - it shields the UDP frame from whatever
upstream bug is clobbering the struct. When a user hits the original
bug, the canary WARN will help isolate the root cause.

The CSI callback reads g_nvs_config.filter_mac_set and filter_mac on
every invocation (100-500 Hz). If wifi_init_sta() corrupts g_nvs_config
(same root cause as the node_id clobber), the callback reads garbage
from the struct, leading to Core 0 LoadProhibited panic after ~2400
callbacks (~70 seconds of operation).

Extends the early-capture pattern from the node_id fix to also copy
filter_mac_set and filter_mac into module-local statics before WiFi
init runs. Adds canary logging to detect filter_mac corruption.

…ies + esptool v5 (rebased #397)

* fix(firmware): move defensive node_id capture before wifi_init_sta()

The original defensive copy in csi_collector_init() (line 172 of main.c)
runs AFTER wifi_init_sta() (line 147), which on some ESP32-S3 devices
corrupts g_nvs_config.node_id back to the Kconfig default of 1.

Reproduced on device 80:b5:4e:c1:be:b8 (ESP32-S3 QFN56 rev v0.2):
  - NVS provisioned with node_id=5
  - Release firmware (no fix): seed receives node_id=1 (clobbered)
  - This patch: seed receives node_id=5 (correct)

Changes:
  - Add csi_collector_set_node_id() called from main.c immediately
    after nvs_config_load(), before wifi_init_sta() runs
  - csi_collector_init() now detects and logs the clobber if early
    capture disagrees with current g_nvs_config value
  - Fallback path preserved: if set_node_id() is never called,
    init() still captures from g_nvs_config (backwards compatible)

The CSI callback reads g_nvs_config.filter_mac_set and filter_mac on

(same root cause as the node_id clobber), the callback reads garbage

* fix(firmware): MGMT-only promiscuous filter to prevent SPI cache crash

The WiFi driver's wDev_ProcessFiq interrupt handler crashes with
LoadProhibited in cache_ll_l1_resume_icache when promiscuous mode
captures MGMT+DATA frames (100-500 interrupts/sec). The high interrupt
rate races with SPI flash cache operations, corrupting cache state.

Changes:
- Promiscuous filter: MGMT+DATA → MGMT-only (~10 Hz beacons)
- CSI config: disable htltf_en and stbc_htltf2_en (LLTF-only)

LLTF provides 64 subcarriers (HT20) — sufficient for presence,
breathing, and fall detection. The 10 Hz beacon rate eliminates
the SPI flash cache contention that caused the crash.

Verified on device 80:b5:4e:c1:be:b8:
- Before: LoadProhibited crash at ~1600-2400 callbacks (every ~70s)
- After: 2700+ callbacks over 4.7 minutes, zero crashes

Backtrace decode confirmed crash in ESP-IDF closed-source WiFi blob:
  _xt_lowint1 → wDev_ProcessFiq → spi_flash_restore_cache
  → cache_ll_l1_resume_icache → EXCVADDR=0x00000004 (NULL deref)

* fix(provision): write-flash → write_flash for esptool v5 compat

esptool v5+ rejects hyphenated subcommands. The provision script
used 'write-flash' which fails with "invalid choice". Changed to
'write_flash' (underscore) which works with both old and new esptool.

* fix(firmware): 50 Hz callback rate gate + sdkconfig extra IRAM opt

- Add early rate gate in wifi_csi_callback at 50 Hz (defense-in-depth,
  does not prevent crash alone but reduces callback execution time)
- Add null-data injection timer infrastructure (disabled — TX adds
  interrupt pressure that triggers the SPI cache crash, RuView#396)
- sdkconfig.defaults: add CONFIG_ESP_WIFI_EXTRA_IRAM_OPT=y
- sdkconfig.defaults: document SPIRAM XIP attempt (crashes differently)

* fix(firmware): address PR #397 review feedback

Applies @ruvnet's five review requests on PR #397 (RuView#397 comment
4289417527):

1. **Inline comment on `provision.py` `write_flash`** — ESP-IDF v5.4
   bundles esptool 4.10.0 (underscore-only). #391's hyphen swap broke
   the documented venv flow; kept the underscore form and added a
   three-line comment warning future maintainers not to "re-fix" it.

2. **Correct `edge_processing.c` sample_rate** (blocking) — changed
   hard-coded `20.0f` → `10.0f` at line 718 so
   `estimate_bpm_zero_crossing()` matches the MGMT-only CSI rate.
   Without this, breathing and heart-rate reports were 2× the true
   value. Added a comment tying the constant to the callback rate gate.

3. **Removed disabled probe-injection infrastructure** — dropped the
   forward declaration, the `CSI_PROBE_INTERVAL_MS` define, six static
   variables (`s_probe_timer`, `s_probe_tx_count`, `s_probe_tx_fail`,
   `s_ap_bssid`, `s_ap_bssid_known`), and three functions
   (`csi_send_probe_request`, `probe_timer_cb`,
   `csi_collector_start_probe_timer`). None were reachable.
   `csi_inject_ndp_frame()` reverted to the original ADR-029 stub.
   Can be revived from this commit's parent if needed.

4. **Cleaned `sdkconfig.defaults`** — removed the SPIRAM prose and
   commented-out `# CONFIG_SPIRAM is not set` line. Kept only the live
   `CONFIG_ESP_WIFI_EXTRA_IRAM_OPT=y` with a concise rationale.

5. **Bumped firmware version 0.6.1 → 0.6.2** and added four
   `[Unreleased]` CHANGELOG entries covering the SPI cache crash fix,
   the `filter_mac` / `node_id` clobber defense, the sample-rate
   correction, and the `write_flash` command-form revert.

Net: +39 / -128 across six files.

Validation in this devcontainer:
- Static sanity on modified C files: braces balance (csi_collector.c
  59/59; edge_processing.c 96/96), zero dangling references to removed
  probe-injection symbols.
- Rust workspace tests and Python proof not executed here — cargo not
  installed and pip blocked by PEP 668. Deferring hardware build +
  flash + miniterm verification to @ruvnet's COM7 per his offer in
  the review comment.

- Add v1/src/integrations/td_osc_bridge.py: WebSocket→OSC bridge that
  forwards person count, presence, x/y/z positions, vitals, node health,
  and signal features to TouchDesigner via UDP OSC. Converts 640×480
  pixel canvas to configurable room metres. Stable slot assignment
  (1..max_persons) prevents unbounded person-ID growth in TD channels.

- Add ui/calibrate.html: mobile-friendly calibration page served at
  /ui/calibrate.html. Start/Stop buttons with live frame counter polling.
  Allows recalibration without the "fresh calibration exists" block.

- Fix calibration always capturing 0 frames (two root causes):
  1. FieldModel default n_subcarriers=56 mismatched ESP32-S3's 114
     subcarriers, causing silent DimensionMismatch on every feed call.
     maybe_feed_calibration now lazily recreates the model on the first
     frame with the actual subcarrier count.
  2. min_calibration_frames=12000 (10 min) made finalize_calibration
     always return InsufficientCalibration. Lowered to 200 (~10 s).

- Add FieldModel::n_subcarriers() accessor for the lazy-init check.

- firmware: read node_id directly from NVS at csi_collector_init() to
  avoid g_nvs_config corruption by WiFi stack init (ruvnet#232/ruvnet#375/ruvnet#385/ruvnet#390).

…d + 2 months of fixes)

The pre-built ESP32-S3 binaries in release_bins/ were built from commit
66e2fa0 (v0.4.3.1-esp32, compiled 2026-03-15) and are now ~2 months
stale. In that window upstream landed several user-visible fixes,
including PR ruvnet#390 "defensive node_id capture prevents runtime clobber",
which we hit on real hardware while bringing up a 3-node deployment.

## The bug users hit with the stale binaries

Symptom: provision with `--node-id 2` (or 3, etc.), boot log says
`Node ID: 2`, but a few hundred ms later csi_collector reports
`node_id=1` and every UDP packet goes out with node_id=1. The MQTT
bridge then registers all nodes as Node 1 in Home Assistant, so a
multi-node deployment looks like a single duplicated node.

Root cause (per ruvnet#232/ruvnet#375/ruvnet#390): the WiFi driver init can corrupt the
g_nvs_config struct on some chips, reverting node_id to its Kconfig
default of 1. The fix is for main.c to copy node_id to a module-local
static (`csi_collector_set_node_id`) BEFORE wifi_init_sta() runs. The
fix is in source but never made it into release_bins/.

## Verification

Reflashed three real ESP32-S3 8MB boards (Waveshare AMOLED 1.8")
in-place without erasing flash — NVS data survived because the
partition table is byte-identical to v0.4.3.1 (only bootloader.bin and
the two app images differ). After upgrade, all three boards now show:

  I (401) csi_collector: Early capture node_id=N (before WiFi init, ruvnet#232/ruvnet#390)
  I (1771) csi_collector: node_id=N verified (early capture matches g_nvs_config)
  I (1801) csi_collector: CSI collection initialized (node_id=N, channel=6)

…with N = 1, 2, 3 respectively, and `Active Nodes: 3` in Home Assistant.

## Files changed

  bootloader.bin             18880 bytes (unchanged size, new ELF)
  esp32-csi-node.bin         990480 -> 1088608 bytes (+98 KiB)
  esp32-csi-node-4mb.bin     773760 -> 872368 bytes (+96 KiB)

Partition tables and ota_data_initial.bin are byte-identical between
v0.4.3.1 and v0.6.4, so the partition layout did not change and the
"flash without erase" upgrade path is safe for existing deployments.

* fix(ci): resolve 3 persistent CI failures + add #679 fix-marker guard

Three jobs have been failing on every push to main since the v1→archive/v1
reorganisation and the softprops/action-gh-release permission tightening:

1. Performance Tests — uvicorn src.api.main:app ran from the repo root with
   no PYTHONPATH, so `src` wasn't importable after v1 moved to archive/v1.
   Added working-directory: archive/v1 to the "Start application" step.
   Added continue-on-error: true — tests/performance/locustfile.py doesn't
   exist yet; job should not gate main merges until a locust suite is added.

2. API Documentation — Generate OpenAPI spec had the same src import failure.
   Added working-directory: archive/v1 to the "Generate OpenAPI spec" step.

3. Notify / Create GitHub Release — softprops/action-gh-release@v2 requires
   contents: write; the notify job had no permissions block so the token was
   read-only, producing a 403 on every main push.
   Added permissions: contents: write to the notify job.

Also adds fix-marker RuView#679 (21 total, all PASS locally):
   Asserts csi_collector_set_node_id() is called in main.c before WiFi init,
   preventing the silent multi-node node_id=1 regression that shipped in the
   v0.4.3.1 release_bins and was fixed + validated on COM7 in PR #681.
