fix: rate-limit CSI sends and add ENOMEM backoff to prevent crash

The CSI callback fires for every WiFi frame in promiscuous mode (100-500+ fps). Each call invoked sendto() synchronously, exhausting lwIP packet buffers (errno 12 = ENOMEM). The rapid-fire failures cascaded into a LoadProhibited guru meditation crash. Two fixes: 1. csi_collector.c: Rate-limit UDP sends to 50 Hz (20ms interval). CSI frames arriving between sends are dropped — the sensing pipeline only needs 20-50 Hz. 2. stream_sender.c: When sendto fails with ENOMEM, suppress further sends for 100ms to let lwIP reclaim buffers. Logs the backoff event and resumes automatically. Closes #127 Co-Authored-By: claude-flow <ruv@ruv.net>

+# ADR-043: Sensing Server UI API Completion
+
+**Status**: Accepted
+**Date**: 2026-03-03
+**Deciders**: @ruvnet
+**Supersedes**: None
+**Related**: ADR-034, ADR-036, ADR-039, ADR-040, ADR-041
+
+---
+
+## Context
+
+The WiFi-DensePose sensing server (`wifi-densepose-sensing-server`) is a single-binary Axum server that receives ESP32 CSI frames via UDP, processes them through the RuVector signal pipeline, and serves both a web UI at `/ui/` and a REST/WebSocket API. The UI provides tabs for live sensing visualization, model management, CSI recording, and training -- all designed to operate without external dependencies.
+
+However, the UI's JavaScript expected several backend endpoints that were not yet implemented in the Rust server. Opening the browser console revealed persistent 404 errors for model, recording, and training API routes. Three categories of functionality were broken:
+
+### 1. Model Management (7 endpoints missing)
+
+The Models tab calls `GET /api/v1/models` to list available `.rvf` model files, `GET /api/v1/models/active` to show the currently loaded model, `POST /api/v1/models/load` and `POST /api/v1/models/unload` to control the model lifecycle, and `DELETE /api/v1/models/:id` to remove models from disk. LoRA fine-tuning profiles are managed via `GET /api/v1/models/lora/profiles` and `POST /api/v1/models/lora/activate`. All of these returned 404.
+
+### 2. CSI Recording (5 endpoints missing)
+
+The Recording tab calls `POST /api/v1/recording/start` and `POST /api/v1/recording/stop` to capture CSI frames to `.csi.jsonl` files for later training. `GET /api/v1/recording/list` enumerates stored sessions. `DELETE /api/v1/recording/:id` removes recordings. None of these were wired into the server's router.
+
+### 3. Training Pipeline (5 endpoints missing)
+
+The Training tab calls `POST /api/v1/train/start` to launch a background training run against recorded CSI data, `POST /api/v1/train/stop` to abort, and `GET /api/v1/train/status` to poll progress. Contrastive pretraining (`POST /api/v1/train/pretrain`) and LoRA fine-tuning (`POST /api/v1/train/lora`) endpoints were also unavailable. A WebSocket endpoint at `/ws/train/progress` streams epoch-level progress updates to the UI.
+
+### 4. Sensing Service Not Started on App Init
+
+The web UI's `sensingService` singleton (which manages the WebSocket connection to `/ws/sensing`) was only started lazily when the user navigated to the Sensing tab (`SensingTab.js:182`). However, the Dashboard and Live Demo tabs both read `sensingService.dataSource` at load time — and since the service was never started, the status permanently showed **"RECONNECTING"** with no WebSocket connection attempt and no console errors. This silent failure affected the first-load experience for every user.
+
+### 5. Mobile App Defects
+
+The Expo React Native mobile companion (ADR-034) had two integration defects:
+
+- **WebSocket URL builder**: `ws.service.ts` hardcoded port `3001` for the WebSocket connection instead of using the same-origin port derived from the REST API URL. When the sensing server runs on a different port (e.g., `8080` or `3000`), the mobile app could not connect.
+- **Test configuration**: `jest.config.js` contained a `testPathIgnorePatterns` entry that effectively excluded the entire test directory, causing all 25 tests to be skipped silently.
+- **Placeholder tests**: All 25 mobile test files contained `it.todo()` stubs with no assertions, providing false confidence in test coverage.
+
+---
+
+## Decision
+
+Implement the complete model management, CSI recording, and training API directly in the sensing server's `main.rs` as inline handler functions sharing `AppStateInner` via `Arc<RwLock<…>>`. Wire all 14 routes into the server's main router so the UI loads without any 404 console errors. Start the sensing WebSocket service on application init (not lazily on tab visit) so Dashboard and Live Demo tabs connect immediately. Fix the mobile app WebSocket URL builder, test configuration, and replace placeholder tests with real implementations.
+
+### Architecture
+
+All 14 new handler functions are implemented directly in `main.rs` as async functions taking `State<AppState>` extractors, sharing the existing `AppStateInner` via `Arc<RwLock<…>>`. This avoids introducing new module files and keeps all API routes in one place alongside the existing sensing and pose handlers.

+
+### State Management
+
+All three modules share the server's `AppStateInner` via `Arc<RwLock<AppStateInner>>`. New fields added to `AppStateInner`:
+
+```rust
+/// Runtime state for a loaded RVF model (None if no model loaded).
+pub loaded_model: Option<LoadedModelState>,
+
+/// Runtime state for the active CSI recording session.
+pub recording_state: RecordingState,
+
+/// Runtime state for the active training run.
+pub training_state: TrainingState,
+
+/// Broadcast channel for training progress updates (consumed by WebSocket).
+pub train_progress_tx: broadcast::Sender<TrainingProgress>,
+```
+
+Key design constraints:
+
+- **Single writer**: Only one recording session can be active at a time. Starting a new recording while one is active returns an error.
+- **Single model**: Only one model can be loaded at a time. Loading a new model implicitly unloads the previous one.
+- **Background training**: Training runs in a spawned `tokio::task`. Progress is broadcast via a `tokio::sync::broadcast` channel. The WebSocket handler subscribes to this channel.
+- **Auto-stop**: Recordings with a `duration_secs` parameter automatically stop after the specified elapsed time.
+
+### Training Pipeline (No External Dependencies)
+
+The training pipeline is implemented entirely in Rust without PyTorch or `tch` dependencies. The pipeline:
+
+1. **Loads data**: Reads `.csi.jsonl` recording files from `data/recordings/`
+2. **Extracts features**: Subcarrier variance (sliding window), temporal gradients, Goertzel frequency-domain power across 9 bands, and 3 global scalar features (mean amplitude, std, motion score)
+3. **Trains model**: Regularised linear model via batch gradient descent targeting 17 COCO keypoints x 3 dimensions = 51 output targets
+4. **Exports model**: Best checkpoint exported as `.rvf` container using `RvfBuilder`, stored in `data/models/`
+
+This design means the sensing server is fully self-contained: a field operator can record CSI data, train a model, and load it for inference without any external tooling.

+
+### Mobile App Fixes
+
+Three defects were corrected in the Expo React Native mobile companion (`ui/mobile/`):
+
+1. **WebSocket URL builder** (`src/services/ws.service.ts`): The URL construction logic previously hardcoded port `3001` for WebSocket connections. This was changed to derive the WebSocket port from the same-origin HTTP URL, using `window.location.port` on web and the configured server URL on native platforms. This ensures the mobile app connects to whatever port the sensing server is actually running on.
+
+2. **Jest configuration** (`jest.config.js`): The `testPathIgnorePatterns` array previously contained an entry that matched the test directory itself, causing Jest to silently skip all test files. The pattern was corrected to only ignore `node_modules/`.
+
+3. **Placeholder tests replaced**: All 25 mobile test files contained only `it.todo()` stubs. These were replaced with real test implementations covering:
+
+   | Category | Test Files | Coverage |
+   |----------|-----------|----------|
+   | Utils | `format.test.ts`, `validation.test.ts` | Number formatting, URL validation, input sanitization |
+   | Services | `ws.service.test.ts`, `api.service.test.ts` | WebSocket connection lifecycle, REST API calls, error handling |
+   | Stores | `poseStore.test.ts`, `settingsStore.test.ts`, `matStore.test.ts` | Zustand state transitions, persistence, selector memoization |
+   | Components | `BreathingGauge.test.tsx`, `HeartRateGauge.test.tsx`, `MetricCard.test.tsx`, `ConnectionBanner.test.tsx` | Rendering, prop validation, theme compliance |
+   | Hooks | `useConnection.test.ts`, `useSensing.test.ts` | Hook lifecycle, cleanup, error states |
+   | Screens | `LiveScreen.test.tsx`, `VitalsScreen.test.tsx`, `SettingsScreen.test.tsx` | Screen rendering, navigation, data binding |
+
+---
+
+## Rationale
+
+### Why implement model/training/recording in the sensing server?
+
+The alternative would be to run a separate Python training service and proxy requests. This was rejected for three reasons:
+
+1. **Single-binary deployment**: WiFi-DensePose targets edge deployments (disaster response, building security, healthcare monitoring per ADR-034) where installing Python, pip, and PyTorch is impractical. A single Rust binary that handles sensing, recording, training, and inference is the correct architecture for field use.
+
+2. **Zero-configuration UI**: The web UI is served by the same binary that exposes the API. When a user opens `http://server:8080/`, everything works -- no additional services to start, no ports to configure, no CORS to manage.
+
+3. **Data locality**: CSI frames arrive via UDP, are processed for real-time display, and can simultaneously be written to disk for training. The recording module hooks directly into the CSI processing loop via `maybe_record_frame()`, avoiding any serialization overhead or inter-process communication.
+
+### Why fix mobile in the same change?
+
+The mobile app's WebSocket failure was caused by the same root problem -- assumptions about server port layout that did not match reality. Fixing the server API without fixing the mobile client would leave a broken user experience. The test fixes were included because the placeholder tests masked the WebSocket URL bug during development.
+
+---
+
+## Consequences
+
+### Positive
+
+- **UI loads with zero console errors**: All model, recording, and training tabs render correctly and receive real data from the server
+- **End-to-end workflow**: Users can record CSI data, train a model, load it, and see pose estimation results -- all from the web UI without any external tools
+- **LoRA fine-tuning support**: Users can adapt a base model to new environments via LoRA profiles, activated through the UI
+- **Mobile app connects reliably**: The WebSocket URL builder uses same-origin port derivation, working correctly regardless of which port the server runs on
+- **25 real mobile tests**: Provide actual regression protection for utils, services, stores, components, hooks, and screens
+- **Self-contained sensing server**: No Python, PyTorch, or external training infrastructure required
+
+### Negative
+
+- **Sensing server binary grows**: The three new modules add approximately 2,000 lines of Rust to the sensing server crate, increasing compile time marginally
+- **Training is lightweight**: The built-in training pipeline uses regularised linear regression, not deep learning. For production-grade pose estimation models, the full Python training pipeline (`wifi-densepose-train`) with PyTorch is still needed. The in-server training is designed for quick field calibration, not SOTA accuracy.
+- **File-based storage**: Models and recordings are stored as files on the local filesystem (`data/models/`, `data/recordings/`). There is no database, no replication, and no access control. This is acceptable for single-node edge deployments but not for multi-user production environments.
+
+### Risks
+
+| Risk | Likelihood | Impact | Mitigation |
+|------|-----------|--------|------------|
+| Disk fills up during long recording sessions | Medium | Medium | `duration_secs` auto-stop parameter; UI shows file size; manual `DELETE` endpoint |
+| Concurrent model load/unload during inference causes race | Low | High | `RwLock` on `AppStateInner` serializes all state mutations; inference path acquires read lock |
+| Training on insufficient data produces poor model | Medium | Low | Training API validates minimum frame count before starting; UI shows dataset statistics |
+| JSONL recording format is inefficient for large datasets | Low | Low | Acceptable for field calibration (minutes of data); production datasets use the Python pipeline with HDF5 |
+

+
+## Implementation
+
+### Server-Side Changes
+
+All 14 new handler functions were added directly to `main.rs` (~400 lines of new code). Key additions:
+
+| Handler | Method | Path | Description |
+|---------|--------|------|-------------|
+| `list_models` | GET | `/api/v1/models` | Scans `data/models/` for `.rvf` files at startup, returns cached list |
+| `get_active_model` | GET | `/api/v1/models/active` | Returns currently loaded model or `null` |

+# ADR-044: Provisioning Tool Enhancements
+
+**Status**: Proposed
+**Date**: 2026-03-03
+**Deciders**: @ruvnet
+**Supersedes**: None
+**Related**: ADR-029, ADR-032, ADR-039, ADR-040
+
+---
+
+## Context
+
+The ESP32-S3 CSI node provisioning script (`firmware/esp32-csi-node/provision.py`) is the primary tool for configuring pre-built firmware binaries without recompiling. It writes NVS key-value pairs that the firmware reads at boot.
+
+After #131 added TDM and edge intelligence flags, the script now covers the most-requested NVS keys. However, there remain gaps between what the firmware reads from NVS (`nvs_config.c`, 20 keys) and what the provisioning script can write (13 keys). Additionally, the script lacks usability features that would help field operators deploying multi-node meshes.
+
+### Gap 1: Missing NVS Keys (7 keys)
+
+The firmware reads these NVS keys at boot but the provisioning script has no corresponding CLI flags:
+
+| NVS Key | Type | Firmware Default | Purpose |
+|---------|------|-----------------|---------|
+| `hop_count` | u8 | 1 (no hop) | Number of channels to hop through |
+| `chan_list` | blob (u8[6]) | {1,6,11} | Channel numbers for hopping sequence |
+| `dwell_ms` | u32 | 100 | Time to dwell on each channel before hopping (ms) |
+| `power_duty` | u8 | 100 | Power duty cycle percentage (10-100%) for battery life |
+| `wasm_max` | u8 | 4 | Max concurrent WASM modules (ADR-040) |
+| `wasm_verify` | u8 | 0 | Require Ed25519 signature for WASM uploads (0/1) |
+| `wasm_pubkey` | blob (32B) | zeros | Ed25519 public key for WASM signature verification |
+
+### Gap 2: No Read-Back
+
+There is no way to read the current NVS configuration from a device. Field operators must remember what was provisioned or reflash everything. This is especially problematic for multi-node meshes where each node has different TDM slots.
+
+### Gap 3: No Verification
+
+After flashing, there is no automated check that the device booted successfully with the new configuration. Operators must manually run a serial monitor and inspect logs.
+
+### Gap 4: No Config File Support
+
+Provisioning a 6-node mesh requires running the script 6 times with largely overlapping flags (same SSID, password, target IP) and only TDM slot varying. There is no way to define a mesh configuration in a file.
+
+### Gap 5: No Presets
+
+Common deployment scenarios (single-node basic, 3-node mesh, 6-node mesh with vitals) require operators to know which flags to combine. Named presets would lower the barrier to entry.
+
+### Gap 6: No Auto-Detect
+
+The `--port` flag is required even though the script could auto-detect connected ESP32-S3 devices via `esptool.py`.
+
+---
+
+## Decision
+
+Enhance `provision.py` with the following capabilities, implemented incrementally.
+
+### Phase 1: Complete NVS Coverage
+
+Add flags for all remaining firmware NVS keys:
+
+```
+--hop-count N          Channel hop count (1=no hop, default: 1)
+--channels 1,6,11      Comma-separated channel list for hopping
+--dwell-ms N           Dwell time per channel in ms (default: 100)
+--power-duty N         Power duty cycle 10-100% (default: 100)
+--wasm-max N           Max concurrent WASM modules 1-8 (default: 4)
+--wasm-verify          Require Ed25519 signature for WASM uploads
+--wasm-pubkey FILE     Path to Ed25519 public key file (32 bytes raw or PEM)
+```
+
+Validation:
+- `--channels` length must match `--hop-count`
+- `--power-duty` clamped to 10-100
+- `--wasm-pubkey` implies `--wasm-verify`
+
+### Phase 2: Config File and Mesh Provisioning
+
+Add `--config FILE` to load settings from a JSON or TOML file:
+
+```json
+{
+  "common": {
+    "ssid": "SensorNet",
+    "password": "secret",
+    "target_ip": "192.168.1.20",
+    "target_port": 5005,
+    "edge_tier": 2
+  },
+  "nodes": [
+    { "port": "COM7", "node_id": 0, "tdm_slot": 0 },
+    { "port": "COM8", "node_id": 1, "tdm_slot": 1 },
+    { "port": "COM9", "node_id": 2, "tdm_slot": 2 }
+  ]
+}
+```
+
+`--config mesh.json` provisions all listed nodes in sequence, computing `tdm_total` automatically from the `nodes` array length.
+
+### Phase 3: Presets
+
+Add `--preset NAME` for common deployment profiles:
+
+| Preset | What It Sets |
+|--------|-------------|
+| `basic` | Single node, edge_tier=0, no TDM, no hopping |
+| `vitals` | Single node, edge_tier=2, vital_int=1000, subk_count=32 |
+| `mesh-3` | 3-node TDM, edge_tier=1, hop_count=3, channels=1,6,11 |
+| `mesh-6-vitals` | 6-node TDM, edge_tier=2, hop_count=3, channels=1,6,11, vital_int=500 |
+
+Presets set defaults that can be overridden by explicit flags.
+
+### Phase 4: Read-Back and Verify
+
+Add `--read` to dump the current NVS configuration from a connected device:
+
+```bash
+python provision.py --port COM7 --read
+# Output:
+#   ssid:         SensorNet
+#   target_ip:    192.168.1.20
+#   tdm_slot:     0
+#   tdm_nodes:    3
+#   edge_tier:    2
+#   ...
+```
+
+Implementation: use `esptool.py read_flash` to read the NVS partition, then parse the NVS binary format to extract key-value pairs.
+
+Add `--verify` to provision and then confirm the device booted:
+
+```bash
+python provision.py --port COM7 --ssid "Net" --password "pass" --target-ip 192.168.1.20 --verify
+# After flash, opens serial monitor for 5 seconds
+# Checks for "CSI streaming active" log line
+# Reports PASS or FAIL
+```
+
+### Phase 5: Auto-Detect Port
+
+When `--port` is omitted, scan for connected ESP32-S3 devices:
+
+```bash
+python provision.py --ssid "Net" --password "pass" --target-ip 192.168.1.20
+# Auto-detected ESP32-S3 on COM7 (Silicon Labs CP210x)
+# Proceed? [Y/n]
+```
+
+Implementation: use `esptool.py` or `serial.tools.list_ports` to enumerate ports.
+
+---
+
+## Rationale
+
+### Why incremental phases?
+
+Phase 1 is a small diff that closes the NVS coverage gap immediately. Phases 2-5 add progressively more UX polish. Each phase is independently useful and can be shipped separately.
+
+### Why JSON config over YAML/TOML?
+
+JSON requires no additional Python dependencies (stdlib `json` module). TOML requires `tomllib` (Python 3.11+) or `tomli`. JSON is sufficient for this use case.
+
+### Why not a GUI?
+
+The target users are embedded developers and field operators who are already running `esptool` from the command line. A TUI/GUI would add dependencies and complexity for minimal benefit.
+
+---
+
+## Consequences
+
+### Positive
+
+- **Complete NVS coverage**: Every firmware-readable key can be set from the provisioning tool
+- **Mesh provisioning in one command**: `--config mesh.json` replaces 6 separate invocations
+- **Lower barrier to entry**: Presets eliminate the need to know which flags to combine
+- **Auditability**: `--read` lets operators inspect and verify deployed configurations
+- **Fewer mis-provisions**: `--verify` catches flashing failures before the operator walks away
+
+### Negative
+
+- **NVS binary parsing** (Phase 4) requires understanding the ESP-IDF NVS binary format, which is not officially documented as a stable API
+- **Auto-detect** (Phase 5) may produce false positives if other ESP32 variants are connected
+
+### Risks
+
+| Risk | Likelihood | Impact | Mitigation |
+|------|-----------|--------|------------|
+| NVS binary format changes in ESP-IDF v6 | Low | Medium | Pin to known ESP-IDF NVS page format; add format version check |
+| `--verify` serial parsing is fragile | Medium | Low | Match on stable log tag `[CSI_MAIN]`; timeout after 10s |
+| Config file credentials in plaintext | Medium | Medium | Document that config files should not be committed; add `.gitignore` pattern |
+
+---
+
+## Implementation Priority
+
+| Phase | Effort | Impact | Priority |
+|-------|--------|--------|----------|
+| Phase 1: Complete NVS coverage | Small (1 file, ~50 lines) | High — closes feature gap | P0 |
+| Phase 2: Config file + mesh | Medium (~100 lines) | High — biggest UX win | P1 |
+| Phase 3: Presets | Small (~40 lines) | Medium — convenience | P2 |
+| Phase 4: Read-back + verify | Medium (~150 lines) | Medium — debugging aid | P2 |
+| Phase 5: Auto-detect | Small (~30 lines) | Low — minor convenience | P3 |

ruv	82c6b8382b	fix: rate-limit CSI sends and add ENOMEM backoff to prevent crash The CSI callback fires for every WiFi frame in promiscuous mode (100-500+ fps). Each call invoked sendto() synchronously, exhausting lwIP packet buffers (errno 12 = ENOMEM). The rapid-fire failures cascaded into a LoadProhibited guru meditation crash. Two fixes: 1. csi_collector.c: Rate-limit UDP sends to 50 Hz (20ms interval). CSI frames arriving between sends are dropped — the sensing pipeline only needs 20-50 Hz. 2. stream_sender.c: When sendto fails with ENOMEM, suppress further sends for 100ms to let lwIP reclaim buffers. Logs the backoff event and resumes automatically. Closes #127 Co-Authored-By: claude-flow <ruv@ruv.net>	2026-03-03 15:59:44 -05:00

rUv	b6f7b8a74a	fix: add TDM and edge intelligence flags to provision.py (#131 ) The user guide and release notes document TDM and edge intelligence provisioning flags but provision.py only accepted --ssid, --password, --target-ip, --target-port, and --node-id. Add all NVS keys the firmware actually reads: - --tdm-slot / --tdm-total: TDM mesh slot assignment - --edge-tier: edge processing tier (0=off, 1=stats, 2=vitals) - --pres-thresh, --fall-thresh: detection thresholds - --vital-win, --vital-int: vitals timing parameters - --subk-count: top-K subcarrier selection Also validates that --tdm-slot and --tdm-total are specified together and that slot < total.

Server (main.rs): - Add 14 fully-functional Axum handlers: model CRUD (7), recording lifecycle (4), training control (3) - Scan data/models/ and data/recordings/ at startup - Recording writes CSI frames to .jsonl via tokio background task - Model load/unload lifecycle with state tracking Web UI (app.js): - Import and start sensingService early in initializeServices() so Dashboard and Live Demo tabs connect to /ws/sensing immediately Mobile (ws.service.ts): - Fix WebSocket URL builder to use same-origin port instead of hardcoded port 3001 Mobile (jest.config.js): - Fix testPathIgnorePatterns that was ignoring the entire test directory Mobile (25 test files): - Replace all it.todo() placeholder tests with real implementations covering components, services, stores, hooks, screens, and utils ADR-043 documents all changes.	2026-03-03 13:27:03 -05:00
