The firmware already implements a captive portal AP fallback in firmware/main/wifi.c: after 10 consecutive WiFi connection failures with exponential backoff (up to 30s between attempts), the firmware transitions to AP mode with SSID \"spaxel-{last4mac}\". However, the captive portal HTTP config page served in this mode is currently a stub and needs to be completed. This bead finishes that implementation and adds the mothership-side offline detection and dashboard alert.\n\n## What Already Exists (Phase 1)\n\nfirmware/main/wifi.c implements the WIFI_STATE_CAPTIVE_PORTAL state transition after failure threshold. The firmware starts a SoftAP with SSID \"spaxel-{last4mac}\" and password-free (open AP). A stub HTTP server exists but serves only a 200 OK response with no content. The DNS server for captive portal hijacking is not yet implemented.\n\n## Captive Portal HTTP Server (Firmware)\n\nUse ESP-IDF's esp_http_server component to serve a config page at http://192.168.4.1/ when in AP mode.\n\nThe config page (served as inline HTML, no external resources — it must work fully offline):\n- Shows current provisioned SSID (from NVS, read-only display)\n- Form: new SSID input, password input, optional mothership host/port\n- Submit button: \"Save and Reconnect\"\n- On form submission: firmware writes new credentials to NVS (wifi_ssid, wifi_pass, optionally mothership_host/port) and calls esp_restart()\n- Minimal HTML with inline CSS: max 4KB so it fits in IRAM. No JavaScript needed.\n- Works on iOS Safari (no JS requirement), Android Chrome, desktop browsers\n\nThe HTTP server must handle the iOS and Android captive portal probe paths:\n- GET /hotspot-detect.html (iOS)\n- GET /generate_204 (Android)\n- GET /ncsi.txt (Windows)\nRespond to all of these with a 302 redirect to http://192.168.4.1/ to trigger the OS captive portal popup.\n\n## DNS Hijacking for Captive Portal Detection\n\nModern mobile OSes detect captive portals by making a DNS lookup for a known hostname (connectivitycheck.android.com, captive.apple.com, etc.) and checking if the response is correct. To trigger the OS captive portal popup automatically (so the user does not need to manually navigate to 192.168.4.1):\n\nImplement a minimal DNS server using lwIP's UDP API. The DNS server binds to UDP port 53 on the SoftAP interface (192.168.4.1). It responds to ALL DNS queries with an A record pointing to 192.168.4.1, regardless of the queried hostname. This causes the OS to detect the captive portal and show the popup.\n\nESP-IDF does not provide a ready-made DNS hijacking component — implement using esp_event_loop and lwIP udp_new()/udp_bind()/udp_recv() APIs. Keep the implementation minimal: parse enough of the DNS query to extract the transaction ID and question name, then build a minimal A record response.\n\n## Mothership Offline Detection and Dashboard Alert\n\nThe mothership detects node disconnection via heartbeat timeout. When a node's WebSocket closes (or health messages stop for > 30s), the mothership:\n1. Sets node status to OFFLINE in the node registry\n2. Broadcasts a node_offline WebSocket message to dashboard: {\"type\":\"node_offline\",\"mac\":\"aa:bb:cc:dd:ee:ff\",\"label\":\"Living Room\",\"last_seen\":\"2026-03-27T14:23:00Z\",\"likely_cause\":\"wifi_loss\"}\n\nThe dashboard shows an offline alert card:\n- \"Node [Living Room] went offline at 14:23. It may need WiFi reconfiguration.\"\n- Shows the captive portal AP SSID to connect to: \"Connect to Wi-Fi network 'spaxel-ff01' to reconfigure\"\n- Troubleshooting steps: 1) Check power LED, 2) Check WiFi router is online, 3) Connect to captive portal if LED is blinking\n\nThe likely_cause field is set by the mothership based on the last health message before disconnect (e.g. low WiFi RSSI in last health message -> \"wifi_range\", no recent health messages at all -> \"unknown\").\n\n## Reconnection and Portal Exit\n\nWhen the user submits new credentials in the captive portal and the node reboots:\n1. The SoftAP goes down (existing connections to \"spaxel-ff01\" are dropped)\n2. The node attempts WiFi connection with new credentials\n3. On success, connects to mothership — mothership sets status to ONLINE and broadcasts node_online event\n4. Dashboard shows reconnection notification: \"Node [Living Room] reconnected successfully\"\n\nIf the new credentials also fail (e.g. user mistyped), the node re-enters captive portal mode after another 10 failures. The portal should display an error on re-entry if the previous attempt failed.\n\n## Implementation Files\n\n- firmware/main/wifi.c: complete captive portal HTTP server, add DNS hijacking task\n- firmware/main/captive_portal.c (new): DNS hijacking task + HTTP handler functions\n- mothership/internal/ingestion/server.go: heartbeat timeout detection, node_offline event\n- mothership/internal/fleet/manager.go: node status tracking (ONLINE/OFFLINE/CAPTIVE_PORTAL)\n- dashboard/js/app.js: node_offline event handler, offline alert card rendering\n\n## Testing Challenges\n\nThis feature is difficult to unit test due to hardware dependency. Recommended approaches:\n1. Firmware: Integration test in QEMU (esp32s3 target) — simulate WiFi failures by mocking the WiFi event loop, verify state machine transitions to CAPTIVE_PORTAL after failure threshold\n2. DNS server: Unit test the DNS response builder function with a fixed query buffer and verify the response parses correctly\n3. HTTP config page: Unit test the form handler that writes to NVS (mock the NVS API)\n4. Mothership: Unit test heartbeat timeout detection with a fake time source, verify node_offline event is emitted\n\n## Acceptance Criteria\n\n- After WiFi failure (10 consecutive failures), node enters AP mode with SSID \"spaxel-{last4mac}\" within 5 minutes of initial loss\n- Mobile device connecting to the captive portal AP automatically sees the OS captive portal popup (tested on iOS 16+ and Android 12+)\n- Config page is served and functional without JavaScript\n- Updating credentials causes node to reboot and reconnect to mothership within 60s\n- Dashboard shows offline node alert within 30s of disconnection\n- Reconnection notification appears in dashboard within 30s of node reconnecting\n- Captive portal DNS server responds correctly to all DNS queries with 192.168.4.1\n- Tests pass","status":"closed","priority":2,"issue_type":"task","created_at":"2026-03-28T01:38:15.579673840Z","created_by":"coding","updated_at":"2026-03-28T05:36:39.291892350Z","closed_at":"2026-03-28T05:36:39.291803146Z","close_reason":"Implemented: firmware/main/wifi.c (fb69190, 89 lines added) — captive portal AP mode (spaxel-XXXX SSID), esp_http_server config page at 192.168.4.1, DNS hijacking to trigger OS captive portal popup, NVS credential update on form submission","source_repo":".","compaction_level":0,"original_size":0,"dependencies":[{"issue_id":"spaxel-16e","depends_on_id":"spaxel-uc9","type":"blocks","created_at":"2026-03-28T03:29:13.901241816Z","created_by":"coding","metadata":"{}","thread_id":""}]} {"id":"spaxel-17u","title":"Phase 9: UX Polish & Accessibility","description":"Goal: Accessible to every household member.

This bead surfaces that data in the browser dashboard — the first human-visible output of the detection pipeline.\n\n## What to Implement\n\n1.

Flags this heuristic as \"possibly wearable\" (not definitive).\n\n## BLERegistry\n\nNew package: mothership/internal/identity/ble.go\n\nBLERegistry struct: backed by SQLite table ble_devices.\n\nSQLite schema:\nCREATE TABLE ble_devices (\n mac TEXT PRIMARY KEY,\n name TEXT,\n manufacturer TEXT,\n device_type TEXT, -- apple_phone, apple_earbuds, fitbit, garmin, tile, samsung, unknown\n label TEXT, -- user-assigned label\n person_id TEXT, -- FK to people.id\n rssi_min INTEGER,\n rssi_max INTEGER,\n rssi_avg INTEGER,\n first_seen DATETIME,\n last_seen DATETIME,\n is_archived BOOLEAN DEFAULT FALSE,\n last_seen_node_mac TEXT\n);\n\nCREATE TABLE people (\n id TEXT PRIMARY KEY, -- uuid\n name TEXT NOT NULL,\n color TEXT, -- hex colour for dashboard rendering\n created_at DATETIME DEFAULT CURRENT_TIMESTAMP\n);\n\nCREATE TABLE person_devices (\n person_id TEXT,\n device_mac TEXT,\n PRIMARY KEY (person_id, device_mac)\n);\n\nBLERegistry methods:\n- ProcessRelayMessage(nodeMac string, devices []BLEDevice): upsert all devices, update last_seen, update RSSI stats\n- GetDevices(includeArchived bool) []BLEDeviceRecord\n- UpdateLabel(mac, label string) error\n- AssignToPerson(mac, personID string) error\n- CreatePerson(name, color string) (Person, error)\n- GetPeople() []Person\n- ArchiveStale(olderThan time.Duration): set is_archived=true for devices not seen for > olderThan\n\n## BLE MAC Randomisation Handling\n\nModern iPhones and Android phones randomise their BLE MAC address periodically (every 10-15 minutes for iPhones, similar for Android). This is a fundamental privacy feature. The implications for spaxel:\n\n1. The same physical phone appears as multiple different MAC addresses in the registry. The BLERegistry will create new entries for each rotated address.\n2. Long-term tracking of phones by MAC is unreliable. The registry will accumulate many entries for a single phone over time.\n3. Workarounds: (a) Apple uses Resolvable Private Addresses (RPA) that can be resolved with the Identity Resolving Key (IRK) — requires pairing, not available without user action. (b) Device name is sometimes consistent across rotations. (c) Wearable devices (Fitbit, Garmin, AirTag) typically do NOT rotate their MACs — they provide reliable long-term tracking.\n\nThe dashboard must clearly explain this limitation in the \"People and Devices\" panel:\n\"Your phone's Bluetooth address changes regularly for privacy reasons. For reliable person tracking, use a Fitbit, Garmin watch, or AirTag, which have stable addresses.\"\n\nGrouping heuristic: if two devices have the same manufacturer data prefix (first 6 bytes) and name, and were never seen simultaneously at high RSSI from the same node, they are likely the same device with a rotated MAC. Surface this as a \"possible duplicate\" suggestion in the UI: \"These may be the same device: [mac1] and [mac2]. Merge?\"\n\n## REST API\n\nGET /api/ble/devices: returns list of BLEDeviceRecord, optionally filtered by ?archived=true\nGET /api/ble/devices/{mac}: returns single device with full history\nPUT /api/ble/devices/{mac}: update label, device_type, or person assignment.

A user who placed a node on a metal shelf, behind a TV, or in a corner will see consistently poor detection without understanding why. Telling users \"your detection quality is low\" is useless without telling them what to do about it. Link weather diagnostics provide root-cause analysis and specific, actionable repositioning advice — including 3D visualisation of why a link is performing poorly and where to move a node to fix it.\n\nThe name \"link weather\" is deliberate: just as weather forecasts present complex atmospheric state in human terms (\"partly cloudy with 60% chance of rain\"), link weather presents complex RF state as: \"Node A to Node B: interference detected. Likely cause: microwave oven or 2.4GHz congestion. Try moving Node B 1.5 metres to the right.\"\n\n## DiagnosticEngine\n\nNew module: mothership/internal/diagnostics/linkweather.go\n\nDiagnosticEngine runs as a background goroutine, consuming link health history from SQLite and emitting Diagnosis structs. It runs a full diagnostic pass every 15 minutes.\n\nA Diagnosis struct contains:\n- LinkID string\n- RuleID string (identifies which rule fired)\n- Severity: INFO, WARNING, ACTIONABLE\n- Title string (human-readable headline)\n- Detail string (explanation of the diagnosis in plain language)\n- Advice string (specific actionable steps)\n- RepositioningTarget *Vec3 (3D position to move the node to, or nil if repositioning is not the solution)\n- RepositioningNodeMAC string (which node to move)\n- ConfidenceScore float64 (how confident the diagnostic engine is in this diagnosis)\n\n## Diagnostic Rules\n\nRule 1: Environmental Change\nTrigger: High baseline drift (>5% per hour) correlated across multiple links simultaneously (>50% of active links).\nTitle: \"Environmental change detected\"\nDetail: \"Multiple sensing links are showing simultaneous baseline shifts. This typically indicates a temperature change, or a large object was moved in the space. The system is adapting automatically.\"\nAdvice: \"No action needed. The baseline will re-stabilise within 30 minutes.\"\nRepositioningTarget: nil\nConfidence: 0.85 if drift is correlated across >50% of links\n\nRule 2: WiFi Congestion or Distance\nTrigger: Packet rate health < 0.8 for more than 10 minutes on a single link.\nTitle: \"Node B has low signal rate\"\nDetail: \"Node [B] is only delivering [N]% of the expected [M] packets per second. The most common causes are distance from the WiFi router or congestion from nearby networks.\"\nAdvice: \"1. Move Node [B] within 10 metres of your WiFi router. 2. If already close, check if the 2.4GHz channel is congested (3+ networks on overlapping channels). 3. ESP32-S3 supports both 2.4GHz and 5GHz — if your router supports 5GHz, update Node B's WiFi config to use the 5GHz SSID.\"\nRepositioningTarget: nil (advice is router proximity, not specific coordinates)\n\nRule 3: Near-Field Metal Interference\nTrigger: Low phase stability (< 0.4) sustained for > 30 minutes during known-quiet periods.\nTitle: \"Metal interference near Node [A]\"\nDetail: \"The sensing link [A to B] has unstable phase measurements even when no one is moving. This is typically caused by metal objects in the near field of the node's antenna (within 10cm): metal shelves, radiators, TV backs, or large appliances.\"\nAdvice: \"Check for metal objects within 10cm of Node [A]. If Node [A] is on a metal surface or shelf, mount it on a non-metal bracket or wall. Try repositioning it 20-30cm away from metal surfaces.\"\nRepositioningTarget: nil (advice is clearance from metal, not a specific position)\n\nRule 4: Fresnel Zone Blockage (Half-Room Dead Zone)\nTrigger: Consistent miss rate (>30% of test walks that should be detected are missed) in a specific area of the room, AND the missing area correlates geometrically with an obstacle in the link's Fresnel zone.\nThis rule requires the feedback loop data (Phase 7, spaxel-i28) — specifically the user-submitted false negatives with position information. If no feedback data is available, this rule can trigger heuristically when one side of the room consistently shows lower blob confidence scores.\nTitle: \"Coverage gap detected — possible obstruction\"\nDetail: \"The area near [zone description] shows lower detection coverage. An obstacle may be blocking the path between Node [A] and Node [B], interrupting their sensing zone.\"\nAdvice: \"Move Node [B] [direction] by approximately [distance] to restore coverage. The target position is marked in green in the 3D view.\"\nRepositioningTarget: computed_optimal_position (see below)\n\nRule 5: Periodic Interference Spikes\nTrigger: Periodic spikes in deltaRMS variance (3-10 events per hour, each lasting 1-3 minutes) not correlated with occupancy data (no people detected moving).\nTitle: \"Periodic interference detected\"\nDetail: \"Node [A] to Node [B] is experiencing regular interference bursts [N] times per hour. This pattern is consistent with a microwave oven, a cordless phone, or a pulsed 2.4GHz source.\"\nAdvice: \"Consider the following: 1. Is Node [A] or Node [B] near a kitchen? Microwave ovens cause strong 2.4GHz interference. 2. A cordless DECT phone or baby monitor near one of the nodes may be the source. 3. Try moving the affected node at least 2 metres from any 2.4GHz appliances.\"\nRepositioningTarget: nil (interference is appliance-specific)\n\n## Repositioning Advice in 3D\n\nFor Rule 4 (Fresnel zone blockage), compute the optimal repositioning target:\n1. Use the GDOP-based coverage optimiser from Phase 5 self-healing fleet (spaxel-jc4) to compute the position that maximises GDOP for the blocked zone while keeping all other nodes fixed.\n2. The optimal position is the computed_optimal_position Vec3.\n3. In the 3D dashboard, render a \"ghost\" node at this position: translucent version of the node mesh, with a dashed line from the current position to the ghost position.\n4. Show expected GDOP improvement: \"Moving Node B here would improve detection in the east corner from [N]% to [M]%.\"\n\n## Weekly Reliability Trends\n\nStore daily health score averages in SQLite: link_health_daily (link_id TEXT, date DATE, avg_health REAL, min_health REAL, max_health REAL, PRIMARY KEY (link_id, date)).\n\nA background job runs daily at midnight and writes the day's health averages from the link health log (link_health_log table: link_id, timestamp, composite_score).\n\nDashboard shows for each link: 7-day sparkline of daily average health score. \"Best day\" annotation (highest average) and \"worst day\" annotation (lowest average). This gives users a sense of long-term reliability.\n\n## Files to Create or Modify\n\n- mothership/internal/diagnostics/linkweather.go: DiagnosticEngine and all 5 rules\n- mothership/internal/diagnostics/reposition.go: repositioning target computation\n- mothership/internal/health/linkhealth.go: add link_health_log table writes\n- dashboard/js/linkhealth.js: link health panel, diagnostics display, ghost node rendering\n- mothership/internal/dashboard/routes.go: GET /api/links/{id}/diagnostics, GET /api/links/{id}/health-history\n\n## Tests\n\n- Test Rule 1 (environmental change): inject simultaneous high-drift events across 60% of links, verify diagnosis fires with Severity=INFO\n- Test Rule 2 (WiFi congestion): inject packet_rate=0.7 for 15 minutes, verify diagnosis fires with appropriate advice text\n- Test Rule 3 (metal interference): inject phase_stability=0.3 for 35 minutes during a quiet window, verify diagnosis fires\n- Test Rule 4 (Fresnel blockage): requires feedback data — inject synthetic false-negative feedback events clustered in one spatial zone, verify diagnosis fires and RepositioningTarget is non-nil\n- Test Rule 5 (periodic interference): inject 5 deltaRMS variance spikes per hour for 2 hours, verify diagnosis fires with correct periodicity estimate\n- Test weekly trend aggregation: inject 7 days of health scores, verify daily averages are correctly computed and stored\n- Test that repositioning target is within room bounds and improves GDOP\n\n## Acceptance Criteria\n\n- All 5 diagnostic rules fire correctly on synthetic test data that matches their trigger conditions\n- Repositioning advice for Rule 4 appears as a ghost node in the 3D dashboard view\n- Expected GDOP improvement shown alongside repositioning ghost node\n- Weekly 7-day sparkline visible in link health panel for each link\n- Diagnostics accessible via API and displayed in Link Health panel on link click\n- Tests pass","status":"closed","priority":3,"issue_type":"task","assignee":"juliet","created_at":"2026-03-28T01:43:13.596164634Z","created_by":"coding","updated_at":"2026-03-29T18:07:39.683230580Z","closed_at":"2026-03-29T18:07:39.683089345Z","close_reason":"done","source_repo":".","compaction_level":0,"original_size":0,"labels":["deferred"],"dependencies":[{"issue_id":"spaxel-32o","depends_on_id":"spaxel-axa","type":"blocks","created_at":"2026-03-28T03:29:14.023730499Z","created_by":"coding","metadata":"{}","thread_id":""}]} {"id":"spaxel-3ps","title":"Detection feedback loop and accuracy tracking","description":"## Background\n\nEvery detection algorithm produces errors. False positives (detected presence when no one is there) are annoying and erode trust. False negatives (missed detection of a real person) are dangerous for safety applications. The feedback loop gives users a direct mechanism to correct errors and the system learns from those corrections. Showing users measurable improvement over time (\"You've provided 47 corrections. Accuracy improved 12% this week\") creates a virtuous engagement loop and transforms users into active participants in improving the system.\n\n## Feedback UI Elements\n\nEvery detection event exposed to the user should have feedback affordances. Three contexts:\n\n1. Dashboard 3D view: Each active track has a small thumbs-up/down icon that appears on hover/focus. Clicking thumbs-down opens a quick inline form.\n\n2. Activity timeline (Phase 8): Every detection event entry has thumbs-up/thumbs-down at the end of the row. Space-efficient: 2 icon buttons.\n\n3. Push notifications: Fall and anomaly notifications include a quick-reply option (via ntfy actions or Pushover callbacks): \"False alarm — clear this.\"\n\n4. \"I was here and wasn't detected\" button: On the timeline panel, a button \"Report missed detection\" opens a form: \"When? [time picker, default: now]\", \"Where? [zone picker]\", \"Who? [person picker, optional]\". Submits as a FALSE_NEGATIVE feedback event with the user-provided position.\n\nFeedback form for thumbs-down:\n- \"What was wrong?\" (radio buttons):\n - \"No one was there (false alarm)\"\n - \"Someone was missed at this location\"\n - \"Wrong person identified\"\n - \"Wrong zone/location\"\n- Optional free-text \"Notes\" field\n- Submit / Cancel\n\n## Feedback Storage\n\nSQLite schema:\nCREATE TABLE detection_feedback (\n id TEXT PRIMARY KEY,\n event_id TEXT, -- references events table (activity timeline)\n event_type TEXT, -- \"blob_detection\", \"zone_transition\", \"fall_alert\", \"anomaly\"\n feedback_type TEXT, -- \"TRUE_POSITIVE\", \"FALSE_POSITIVE\", \"FALSE_NEGATIVE\", \"WRONG_IDENTITY\", \"WRONG_ZONE\"\n details_json TEXT, -- {\"zone_id\":\"...\", \"person_id\":\"...\", \"notes\":\"...\"}\n timestamp DATETIME DEFAULT CURRENT_TIMESTAMP,\n applied BOOLEAN DEFAULT FALSE, -- set to TRUE after weight refinement processes it\n processed_at DATETIME\n);\n\nThe applied flag enables incremental processing: the weight learner (Phase 7 self-improving localisation) queries WHERE applied = FALSE, processes batches, and marks them TRUE.\n\n## Accuracy Metrics\n\nCompute precision/recall/F1 per link, per zone, and per person weekly. This requires knowing the true positives, false positives, and false negatives.\n\nGround truth sources:\n- User thumbs-up -> TRUE_POSITIVE for the corresponding detection event\n- User thumbs-down (false alarm) -> FALSE_POSITIVE for the detection event\n- User \"missed detection\" report -> FALSE_NEGATIVE for the reported time/zone\n\nNote: ground truth is sparse — users will not feedback every event. We use the feedback we have as a sample. Assume events without feedback are TRUE_POSITIVE for the purpose of precision estimates (conservative: this means precision is an upper bound, not exact).\n\nMetrics computed weekly:\n- precision = TP / (TP + FP) — of all detections, what fraction were correct\n- recall = TP / (TP + FN) — of all true presence events, what fraction were detected\n- F1 = 2 * precision * recall / (precision + recall)\n- Per-link metrics: which links have the most false positives (worst precision)\n- Per-zone metrics: which zones are most often missed (worst recall)\n\nStorage: detection_accuracy (week TEXT, scope_type TEXT, scope_id TEXT, precision REAL, recall REAL, f1 REAL, tp_count INT, fp_count INT, fn_count INT, computed_at DATETIME).

With 4+ links we can localise people to ±0.5–1.0m using Fresnel zone weighted localization. This is the core spatial intelligence of spaxel. The physics: WiFi CSI is most sensitive to motion within the first Fresnel zone (an ellipsoid between TX and RX). The approach: for each occupancy grid voxel, compute its weight for each link based on Fresnel zone intersection, multiply by that link's deltaRMS, sum contributions, extract blob peaks.\n\n## What to Implement\n\nNew package: mothership/internal/fusion/\n\n### OccupancyGrid\n- mothership/internal/fusion/grid.go\n- 3D float32 grid, configurable resolution (default 0.25m)\n- Dimensions from room config (width, depth, height in meters)\n- Methods: Reset(), Set(x,y,z int, val float32), Get(x,y,z int) float32, Dims() (nx,ny,nz int)\n\n### Fresnel zone geometry\n- mothership/internal/fusion/fresnel.go\n- FresnelWeight(voxelPos, txPos, rxPos vec3, wavelength float64) float64\n- For 5GHz WiFi: wavelength = 0.06m\n- A voxel is in the first Fresnel zone if: d1+d2 <= dist(tx,rx) + wavelength/2\n where d1 = dist(voxel, tx), d2 = dist(voxel, rx)\n- Weight = deltaRMS × exp(-excess_path_length² / (2×0.1²))\n where excess_path_length = (d1+d2) - dist(tx,rx)\n- Weight = 0 outside Fresnel zone\n\n### FusionEngine\n- mothership/internal/fusion/engine.go\n- Inputs: ProcessorManager (from signal package), NodeRegistry (from fleet/session)\n- Runs at 10Hz via time.Ticker\n- Each tick: reset grid, for each active link get deltaRMS from ProcessorManager, for each voxel compute FresnelWeight × deltaRMS, accumulate to grid\n- Output: call BlobExtractor.Extract(grid), broadcast via dashboard hub as 'blob_update' JSON message\n\n### BlobExtractor\n- mothership/internal/fusion/blobs.go\n- Find 3D local maxima in the grid above threshold (default 0.02)\n- Non-maximum suppression: suppress any peak within 0.5m of a higher peak\n- Output: []BlobDetection{Position vec3, Confidence float32, Radius float32}\n- Limit to max 10 blobs\n\n### Room config\n- Add to mothership config (JSON): room.width_m, room.depth_m, room.height_m (defaults: 5, 5, 2.5)\n- Node positions: initially from fleet manager, defaulting to corners if unset\n\n## Key Files\n- mothership/internal/signal/processor.go — GetAllMotionStates()\n- mothership/internal/dashboard/hub.go — Broadcast() for blob_update\n- New: mothership/internal/fusion/grid.go, fresnel.go, engine.go, blobs.go + tests\n\n## Acceptance Criteria\n- FusionEngine produces blob_update WebSocket messages at 10Hz\n- Single active link produces blob peak along the TX-RX axis\n- Two crossing links produce peak near their intersection\n- BlobExtractor correctly suppresses nearby peaks\n- FresnelWeight returns 0 for voxels clearly outside the Fresnel zone\n- go test ./internal/fusion/... passes","status":"closed","priority":2,"issue_type":"task","created_at":"2026-03-28T03:30:50.362272102Z","created_by":"coding","updated_at":"2026-03-28T05:36:26.188829209Z","closed_at":"2026-03-28T05:36:26.188507646Z","close_reason":"Implemented: fusion/fusion.go + fusion/grid3d.go (9c56a37) — 3D occupancy grid 0.25m res, Fresnel zone ellipsoid weighting, FusionEngine 10Hz, BlobExtractor with NMS","source_repo":".","compaction_level":0,"original_size":0,"dependencies":[{"issue_id":"spaxel-6th","depends_on_id":"spaxel-cxm","type":"blocks","created_at":"2026-03-28T03:30:50.362272102Z","created_by":"coding","metadata":"{}","thread_id":""}]} {"id":"spaxel-72t","title":"Provisioning payload and NVS write","description":"## Background\n\nWhen a new node is provisioned, it needs WiFi credentials (SSID + password) and a unique node ID (for use in the hello message and as a persistent identifier). The provisioning payload is assembled by the mothership and sent to the firmware over serial during onboarding, or can also be sent over the WebSocket after reconnect. Getting this right is foundational to the security and identity model of the entire system.\n\n## Why Mothership-Generated Node IDs?\n\nRather than generating a random ID on device, having the mothership assign node IDs allows it to: track provisioned-but-never-connected nodes for inventory management, support re-provisioning with ID continuity (same physical device gets same ID after factory reset), prevent ID collisions in multi-node deployments, and maintain a token-based security model where only provisioned nodes can connect.\n\n## NVS Schema\n\nThe firmware NVS schema is defined in firmware/main/spaxel.h (schema version 1). Keys and types:\n- wifi_ssid (string, max 32 chars)\n- wifi_pass (string, max 64 chars)\n- node_id (uint16, assigned by mothership)\n- node_token (string, 12-char hex, assigned by mothership)\n- mothership_host (string, empty = use mDNS)\n- mothership_port (uint16, default 8080)\n- role (uint8, 0=rx, 1=tx, 2=tx-rx, 3=passive)\n- sample_rate (uint16, default 20 Hz)\n- schema_ver (uint8, current = 1)\n\n## Mothership API\n\nPOST /api/provision\nRequest body: {\"ssid\": \"MyWifi\", \"password\": \"secret\", \"label\": \"Living Room Node\"}\nResponse: {\"node_id\": 42, \"provision_token\": \"a3f7b2c1d8e9\", \"config_blob\": \"{...json...}\"}\n\nThe config_blob is a JSON string encoding all NVS keys listed above. It is passed verbatim to the firmware over serial or WebSocket. The firmware parses it, writes each key to NVS, and reboots.\n\nExample config_blob:\n{\"wifi_ssid\":\"MyWifi\",\"wifi_pass\":\"secret\",\"node_id\":42,\"node_token\":\"a3f7b2c1d8e9\",\"mothership_host\":\"\",\"mothership_port\":8080,\"role\":0,\"sample_rate\":20,\"schema_ver\":1}\n\n## Firmware Provisioning Handling\n\nTwo provisioning paths:\n\n1. Serial provisioning (onboarding wizard path): Before WiFi is connected, the firmware listens on UART0 (115200 baud) for a JSON line starting with {\"provision\":. On receipt, write to NVS and reboot. This path works even before WiFi credentials are configured.\n\n2. WebSocket provisioning (re-provisioning path): A new downstream command type \"provision\" alongside existing role/config/ota/reboot in firmware/main/websocket.c. Allows the mothership to update credentials or reset a node over the air. This is useful for credential rotation without physical access.\n\n## Security Model\n\nThe provision_token is used as a bearer token in the WebSocket Authorization header (Authorization: Bearer ) for all subsequent connections. The mothership validates the token on every connection attempt against the provisioned_nodes SQLite table. Nodes without a valid token receive a {type:\"reject\"} downstream message and the connection is closed.\n\nToken format: 12 lowercase hex characters (48 bits of entropy). Generated server-side using crypto/rand. Not derivable from node_id or MAC address.\n\n## SQLite Storage\n\nAdd a provisioned_nodes table to the mothership SQLite database:\nCREATE TABLE provisioned_nodes (\n node_id INTEGER PRIMARY KEY,\n mac TEXT,\n token TEXT NOT NULL,\n label TEXT,\n provisioned_at DATETIME DEFAULT CURRENT_TIMESTAMP,\n first_seen DATETIME,\n last_seen DATETIME,\n firmware_version TEXT,\n current_role INTEGER DEFAULT 0\n);\n\nThe mac field is populated when the node first connects and sends its hello message. Before first connection, mac is NULL (node is provisioned but not yet seen).\n\n## Implementation Location\n\n- mothership/internal/provision/handler.go: POST /api/provision handler\n- mothership/internal/provision/store.go: SQLite CRUD for provisioned_nodes\n- mothership/internal/ingestion/auth.go: WebSocket token validation on connection\n- firmware/main/websocket.c: add \"provision\" downstream command type\n- firmware/main/wifi.c: add serial JSON provisioning path on UART0 (pre-WiFi)\n\n## Re-provisioning\n\nIf a node already exists in provisioned_nodes (matched by mac), the mothership can re-provision it with a new token.

Deviations from these patterns — unexpected late-night presence, unknown BLE devices, motion during away mode — can indicate security events. Security mode explicitly arms anomaly detection with immediate alerts and a comprehensive alert chain, transforming spaxel into a basic home security system.\n\n## Normal Behaviour Model\n\nAnomalyDetector maintains a statistical model of normal behaviour per (hour_of_week, zone_id) slot. For each slot:\n- expected_occupancy: whether this zone is typically occupied at this time (fraction of historical samples that had occupancy > 0)\n- typical_person_count: mean occupant count\n- typical_ble_devices: set of BLE device MACs typically present (with minimum frequency threshold: seen in > 50% of this hour_of_week slot)\n\nThe model is updated weekly from the activity history and zone transition history. A minimum of 7 days of data is required before anomaly detection activates. Before 7 days: no anomaly alerts fire.\n\nNew file: mothership/internal/analytics/anomaly.go\n\n## Anomaly Scoring\n\nFour anomaly types, each with a base score contribution:\n\n1. Unusual hour presence (score: 0.7 by default, 0.9 in security mode):\n Motion detected in zone Z at hour H, but expected_occupancy for (H, Z) < 0.1 (this zone is empty >90% of the time at hour H historically). Apply time-of-day sensitivity: late night (00:00-06:00) has 1.5x multiplier.\n\n2. Unknown BLE device (score: 0.5 by default, 0.8 in security mode):\n BLE device with RSSI > -60 dBm (close range) that is not in the registered device list AND has not been seen before (not even in the archive). If it was seen once before but not regularly, score = 0.3.\n\n3. Motion during away mode (score: 0.95, always immediate):\n Any presence detected when SystemMode == AWAY. By definition anomalous — all registered people are absent. This always fires an alert regardless of model training status.\n\n4. Unusual dwell duration (score: 0.4):\n Person present in zone for > 5x the historical mean dwell time for that (person, zone, hour_of_week) combination. May indicate a person is incapacitated (fell and can't get up) rather than a security event — cross-check with fall detection before escalating.\n\nComposite anomaly score: max(individual scores) for the most anomalous concurrent event. Alert threshold: score > 0.6 (default mode), score > 0.4 (security mode).\n\n## Security Mode\n\nSecurityMode is an extension of the SystemMode. When SystemMode is AWAY:\n- All anomaly detection thresholds are lowered (as per scores above)\n- Alert chain is immediate (no T+2min or T+5min delays — fires immediately)\n- Quiet hours are suppressed (all alerts bypass quiet hours when in security mode)\n- All four anomaly types are active regardless of model training status (even before 7 days)\n\nAuto-away detection:\n- Condition: all registered person_ids have had no BLE device seen by any node for > 15 minutes\n- On condition met: set SystemMode = AWAY. Log: \"Auto-away activated — all BLE devices absent\"\n- Broadcast system_mode_change WebSocket event to dashboard\n\nAuto-disarm:\n- Condition: any registered person's BLE device seen with RSSI > -70 dBm at any node\n- On condition met: set SystemMode = HOME. Clear security alerts (or keep them acknowledged-pending).\n- Broadcast system_mode_change event\n- Show \"Welcome home\" card in dashboard if identity is known: \"Alice arrived home.\"\n\nManual override: dashboard has a Home/Away/Sleep toggle that overrides auto-detection. Once manually set, auto-detection is paused for 30 minutes (avoids immediate re-trigger).\n\n## Alert Chain\n\nOn anomaly score > threshold:\n\n1. T+0s: Dashboard alarm overlay (red full-screen banner, z-index: top):\n \"Anomaly detected: [description]. [Acknowledge] [View in 3D] [Dismiss]\"\n Description examples: \"Motion detected in Kitchen at 3:12am (unusual hour)\", \"Unknown device detected near front door\", \"Motion detected while everyone is away\"\n\n2. T+0s (security mode) or T+30s (normal mode): push notification via configured channel with floor-plan thumbnail (using notification module, spaxel-zpt)\n\n3. T+0s (security mode) or T+2min (normal mode): webhook/MQTT via automation engine (trigger type: anomaly)\n\n4. T+5min (without acknowledgement): escalation webhook (secondary URL in settings)\n\nAcknowledge: acknowledges the alert, logs in activity timeline with current time, stops escalation timers. Shows brief form: \"What was this?\" — Expected/known event / Genuine intrusion / False alarm. This feeds the false positive rate for the anomaly model.\n\n## Detection History and Visualisation\n\nAll anomaly events are logged in the activity timeline (Phase 8). The 3D view adds an \"Anomaly\" layer:\n- When an active unacknowledged anomaly exists, the relevant zone pulses with a red overlay in the 3D scene\n- Anomaly events in the timeline are marked with a red shield icon\n\nWeekly anomaly summary: \"0 anomalies this week\" (reassuring) or \"3 anomalies detected: 2 false alarms, 1 unacknowledged.\"\n\n## Files to Create or Modify\n\n- mothership/internal/analytics/anomaly.go: AnomalyDetector, normal behaviour model\n- mothership/internal/fleet/manager.go: SystemMode integration, auto-away detection, BLE presence tracking for auto-disarm\n- dashboard/js/anomaly.js: alarm overlay, acknowledge UI\n- mothership/internal/dashboard/routes.go: GET /api/mode, POST /api/mode, GET /api/anomalies/history\n- mothership/internal/events/events.go: AnomalyEvent type\n\n## Tests\n\n- Test anomaly score for \"unusual hour presence\": expected_occupancy=0.05 at 3am -> score fires\n- Test \"unknown BLE device\": inject device MAC not in registry at RSSI -55 -> anomaly fires\n- Test \"motion during away\": set SystemMode=AWAY, inject presence event -> immediate alert fires regardless of thresholds\n- Test auto-away: all BLE devices absent for 900s -> SystemMode becomes AWAY\n- Test auto-disarm: device seen at RSSI=-65 -> SystemMode becomes HOME\n- Test alert chain timing in normal mode: alert at T+0, notification at T+30s, webhook at T+2min\n- Test security mode immediate alert chain: all three fire at T+0\n- Test acknowledgement cancels pending escalation timers\n\n## Acceptance Criteria\n\n- Anomaly fires correctly for unexpected late-night motion after 7 days of baseline\n- Security mode auto-activates when all registered BLE devices absent for 15 minutes\n- Alert chain fires in correct sequence for both normal and security mode\n- Auto-disarm triggers correctly when first registered BLE device returns\n- Dashboard alarm overlay is clearly visible (full-screen red banner) on anomaly detection\n- Zone pulsing in 3D view during active unacknowledged anomaly\n- Acknowledgement and feedback form records correctly\n- Tests pass","status":"open","priority":3,"issue_type":"task","created_at":"2026-03-28T01:53:44.888473549Z","created_by":"coding","updated_at":"2026-03-30T16:27:42.698511Z","source_repo":".","compaction_level":0,"original_size":0,"labels":["deferred"]} {"id":"spaxel-896","title":"Build dashboard panel/modal/sidebar UI framework","description":"## Problem\n\nThe dashboard is currently a single live 3D view with no panel system.

The onboarding wizard is the centrepiece of this experience. It uses the Web Serial API (available in Chrome/Edge) to communicate with the ESP32 over USB — no driver installation needed, no CLI, no app download. The wizard is embedded in the existing mothership dashboard, accessible at /onboard.\n\n## Why Web Serial?\n\nThe alternative approaches — a dedicated mobile app, a WiFi provisioning AP, or a CLI tool — all have significant UX friction. Web Serial lets us flash firmware, provision WiFi credentials, and guide the user through calibration all in one browser session. The dashboard already knows the mothership IP/port. Chrome and Edge (95%+ of desktop browser market) support Web Serial natively since 2021. The only caveat is that Web Serial is not available in Firefox or Safari — this must be documented prominently at the start of the wizard.\n\n## Wizard Steps\n\n1. **Browser check**: Detect navigator.serial availability. If missing, show: 'Please use Google Chrome or Microsoft Edge to use the setup wizard. Firefox and Safari do not support USB device access.'\n\n2. **Connect device**: Call navigator.serial.requestPort(). Guide the user to hold BOOT button while plugging in if the device does not appear. Show a GIF or SVG illustration of the ESP32-S3 board with the BOOT button highlighted.\n\n3. **Flash firmware** (if not already spaxel firmware): Use esp-web-tools (espressif/esp-web-tools, CDN: https://unpkg.com/esp-web-tools@10/dist/web/install-button.js). This open-source library handles the full ESP32 flashing pipeline via Web Serial, including ROM bootloader protocol, chip detection, and progress reporting. It needs a firmware manifest.json at GET /api/firmware/manifest describing binary addresses and offsets. Show a progress bar during flashing. Estimated time: 45-90 seconds.\n\n4. **Provision WiFi**: Show a form for SSID and password. Optional: mothership host/port override (for non-mDNS setups). Assemble the provisioning payload and send to the ESP32 over serial as JSON (see Provisioning Payload bead for format). If using esp-web-tools, the provisioning can be injected via custom serial commands after flashing.\n\n5. **Detect mothership**: Once provisioned and rebooted, the ESP32 boots and discovers the mothership via mDNS (spaxel-mothership.local) or the configured host. Poll GET /api/nodes every 3s for up to 120s waiting for the new node to appear. Show animated 'Connecting...' indicator. On timeout: show WiFi troubleshooting guidance (5GHz check, SSID typo check, distance check).\n\n6. **Guided calibration**: Show the CSI waveform for the new node's links as they come online. Steps:\n a. 'Walk around your space for 30 seconds' — CSI amplitude should show activity. If flat: check node orientation.\n b. 'Stand still at the far end of the room' — capture baseline. Show countdown. Green check when baseline is captured.\n c. 'Walk through the centre of the room' — Fresnel zone lights up in 3D view, blob appears. 'The sensor can see you!'\n d. 'Sit down and stay still for 30 seconds' — test stationary detection (if Phase 5 available). Otherwise skip.\n\n7. **Node placement guidance**: Transition to the coverage painting UI (spaxel-qq6) for optimal node positioning. Show GDOP overlay for the current node placement. Suggest additional node positions if coverage is poor.\n\n## Files to Create/Modify\n\n- dashboard/js/onboard.js: wizard state machine, Web Serial API calls, step rendering\n- dashboard/index.html: add /onboard route and wizard container div, import esp-web-tools\n- mothership/internal/dashboard/routes.go (or similar): add GET /api/firmware/manifest route\n- mothership/internal/dashboard/hub.go: no changes needed (wizard uses REST polling, not WebSocket for this flow)\n\n## esp-web-tools Integration\n\n\n\nManifest served at GET /api/firmware/manifest:\n\n\n## Wizard State Machine\n\nStates: BROWSER_CHECK → CONNECT_DEVICE → FLASH_FIRMWARE → PROVISION_WIFI → DETECT_NODE → CALIBRATE → PLACEMENT → COMPLETE\n\nEach state has: render() function, onEnter() side effects, onNext() transition, onBack() for revert, onError() for failure handling.\n\nPersisted in sessionStorage so a page refresh during onboarding resumes from the last step (critical for the reboot-then-detect step).\n\n## Error Handling\n\nMap every known failure to a human-friendly message:\n- 'NotFoundError: No port selected' → 'No device detected. Make sure the USB cable is connected and hold the BOOT button while plugging in.'\n- 'NetworkError' during flash → 'The connection was interrupted. Check the USB cable is not loose and try again.'\n- Node not appearing after 120s → 'Your node connected to WiFi but cannot reach the mothership. Check: 1) Your router blocks device-to-device communication (AP isolation). 2) The mothership address is correct. 3) Your network uses a VLAN that separates devices.'\n- Wrong SSID/password → Node will fall into captive portal mode after 10 failures, triggering a 'Captive portal detected' guidance flow.\n\nNever show stack traces, WebSocket error codes, or Go error strings to the user.\n\n## Tests\n\n- Mock navigator.serial API in Jest (using jest-serial-port or a hand-written mock) to test wizard state transitions without real hardware\n- Test that provisioning payload is correctly assembled and sent over the mocked serial port\n- Test that polling GET /api/nodes correctly detects node appearance and transitions to DETECT_NODE → CALIBRATE\n- Test that BROWSER_CHECK step correctly detects missing serial API and shows the correct error\n- Test that sessionStorage correctly restores wizard state on page refresh at each step\n\n## Acceptance Criteria\n\n- Wizard completes in under 5 minutes on a fresh ESP32-S3 with a working WiFi network\n- User sees live CSI waveform during calibration step\n- Node appears in dashboard after wizard completion, with correct label\n- All known error conditions show human-friendly guidance, not technical errors\n- All existing dashboard tests pass\n- Wizard state is resumable after page refresh","status":"tombstone","priority":2,"issue_type":"task","created_at":"2026-03-28T01:34:58.168170967Z","created_by":"coding","updated_at":"2026-03-28T01:35:25.110026775Z","closed_at":"2026-03-28T01:35:25.110026775Z","source_repo":".","deleted_at":"2026-03-28T01:35:25.110008642Z","deleted_by":"coding","delete_reason":"delete","original_type":"task","compaction_level":0,"original_size":0} {"id":"spaxel-b6a","title":"Implement calibration POST endpoint","description":"## Task\nImplement POST /api/floorplan/calibrate endpoint.\n\n## Specification\n- Accept {ax,ay,bx,by,distance_m,rotation_deg}: two pixel coordinates and their real-world distance\n- Compute and persist pixel-to-meter transform to SQLite floorplan table\n\n## Acceptance\n- Calibration data persists to SQLite floorplan table","status":"closed","priority":2,"issue_type":"task","assignee":"charlie","created_at":"2026-04-07T17:55:52.516620827Z","created_by":"coding","updated_at":"2026-04-07T18:53:06.721066Z","closed_at":"2026-04-07T18:53:06.720893263Z","close_reason":"done","source_repo":".","compaction_level":0,"original_size":0,"labels":["mitosis-child","mitosis-depth:1","parent-spaxel-klk"]} @@ -83,10 +83,10 @@ {"id":"spaxel-mul","title":"Implement Automation Triggers REST endpoints","description":"Implement CRUD endpoints for triggers: GET/POST /api/triggers, PUT/DELETE /api/triggers/{id}.

The CSI fusion engine (spaxel-m9a) and blob tracker (spaxel-n9n) tell us where anonymous humanoid figures are located in 3D space. Identity matching bridges these two systems: given named BLE devices with per-node RSSI observations, and anonymous CSI blobs with estimated 3D positions, assign device identities to blobs.\n\nWhen a match is confident, the humanoid figure in the 3D view gains a name label and person colour. \"Alice is in the Kitchen\" becomes a real-time fact rather than an approximation.\n\n## RSSI Triangulation Algorithm\n\nFor each BLE device with observations from multiple nodes in the current scan cycle (last 5 seconds):\n\nStep 1: Convert RSSI to distance for each observing node.\nDistance model: d = d0 * 10^((RSSI_ref - RSSI) / (10 * n))\nParameters: d0 = 1.0m (reference distance), RSSI_ref = -65 dBm (RSSI at 1m in typical indoor environment), n = 2.5 (indoor path loss exponent — typical range 2.0-3.5; 2.5 is a reasonable default for residential spaces).\n\nStep 2: With 2+ nodes, perform weighted least squares triangulation.\nPosition estimate: argmin_P { sum_i w_i * (|P - node_i| - d_i)^2 }\nwhere w_i = 1/sigma_i^2, sigma_i = d_i * ln(10) / (10 * n) * RSSI_noise_sigma (typically 5 dBm).\nSolve with 3-5 iterations of gradient descent or Gauss-Newton (the system is nonlinear).\nWith 1 node: only an approximate range estimate; triangulation confidence = 0.2.\nWith 2 nodes: 2D position estimate on a circle/arc; confidence = 0.5.\nWith 3+ nodes: full 2D position estimate with residual as quality indicator; confidence = min(1.0, 0.7 + 0.1 * (n-3)) where n is node count.\n\nStep 3: Assign to nearest CSI blob.\nFor each triangulated BLE position, find the nearest active CSI blob (from TrackManager) within a 2-metre search radius.

Every link's contribution to the 3D occupancy grid is weighted by how much of the candidate voxel falls within the first Fresnel zone ellipsoid. When debugging why localisation is placing a blob in the wrong position, being able to see the actual Fresnel ellipsoids for each active link — overlaid on the 3D scene — instantly reveals whether the zones are covering the right area.\n\nThis is a pure debug/developer tool. It is toggle-able (off by default) and intended for system tuners and developers, not end users. The explainability overlay (spaxel-ez4) already shows Fresnel ellipsoids for a specific selected blob. The Fresnel zone debug overlay shows them persistently for all active links simultaneously.\n\n## Ellipsoid Geometry (Recap)\n\nFor each active link with TX at position P1 and RX at position P2:\n- Link distance d = |P1 - P2|\n- WiFi channel wavelength lambda: 5 GHz -> lambda = 0.06m, 2.4 GHz -> lambda = 0.125m. Use the channel reported in the node's hello message (or the channel from the link's last received CSI frame header).\n- Semi-major axis: a = (d + lambda/2) / 2\n- Semi-minor axis: b = sqrt(a^2 - (d/2)^2)\n- Ellipsoid centre: midpoint(P1, P2)\n- Ellipsoid orientation: major axis along the P1->P2 unit vector\n\nThe first Fresnel zone ellipsoid represents the region where a point reflector would shorten the signal path by at most half a wavelength relative to the direct path. Motion within this region has maximum impact on CSI.\n\n## Three.js Rendering\n\nEllipsoid mesh construction:\n1. Start with THREE.SphereGeometry(1, 32, 16) — a unit sphere\n2. Apply non-uniform scaling: new THREE.Vector3(a, b, b) via mesh.scale.set(a, b, b)\n3. Rotate to align with the link axis: compute the quaternion that maps (1,0,0) to the P1->P2 unit vector using THREE.Quaternion.setFromUnitVectors(new THREE.Vector3(1,0,0), linkAxis)\n4. Apply the quaternion to mesh.quaternion\n\nMaterial: TWO materials:\n- Wireframe: THREE.LineSegments with EdgesGeometry for crisp wireframe edges, line color matching the link line colour, opacity 0.6\n- Fill: THREE.MeshBasicMaterial with transparent=true, opacity 0.08, colour matching the link, depthWrite=false (so the fill doesn't obscure other geometry)\n\nLayer toggle: add \"Fresnel Zones\" checkbox to the 3D layer control panel (in the \"Debug\" section, only visible when expert mode is active). Default: off. When toggled on, add all ellipsoid meshes to the scene. When toggled off, remove them.\n\n## Per-Link Controls\n\nWhen a user hovers over a Fresnel ellipsoid in the 3D scene (using Three.js raycasting):\n- The corresponding link line highlights (brightness increase)\n- A tooltip appears (HTML overlay, positioned at screen coordinates of the hover point):\n \"Link: [tx_label] to [rx_label]\n Fresnel zone radius at midpoint: {b:.2f}m\n Link distance: {d:.2f}m\n Wavelength: {lambda:.3f}m (channel {ch})\n Link health: {health_score:.0%}\"\n\nClicking an ellipsoid:\n- Selects the corresponding link in the link panel (sidebar)\n- Highlights the link entry in the link list\n\n## Performance Considerations\n\nWith 6 active links, we render 6 pairs of meshes (wireframe + fill = 12 Three.js objects). This is negligible for any modern GPU. However, the wireframe geometry uses EdgesGeometry which creates one Line for each edge — for a sphere with 32 horizontal and 16 vertical segments, that's approximately 1000 line segments per ellipsoid. At 6 links, 6000 line segments total. This should render at 60 fps on any modern device, but if performance is an issue on mobile, reduce the sphere segment count to 16x8 when the debug overlay is active on mobile viewports.\n\nPre-compute at link addition time: when a new link is registered (node hello + peer MAC), compute the ellipsoid geometry and add it to the scene (hidden if the layer is off). Update on node position change. Remove when link becomes inactive (no frames for > 30s).\n\n## Relationship to Explainability Overlay\n\nThe Fresnel zone debug overlay (this bead) and the detection explainability overlay (spaxel-ez4) both render Fresnel ellipsoids. They share the same geometry computation code (dashboard/js/fresnel.js — the ellipsoid helper function). The difference:\n- This overlay: shows all active link ellipsoids simultaneously, toggle-able layer\n- Explainability overlay: shows only contributing link ellipsoids for a specific selected blob, in explain mode\n\nBoth import from fresnel.js. The helper function FresnelEllipsoid(P1, P2, lambda) returns a Three.js Mesh ready for scene insertion.\n\n## Files to Create or Modify\n\n- dashboard/js/fresnel.js: FresnelEllipsoid helper function (shared with explainability)\n- dashboard/js/layers.js: add \"Fresnel Zones\" toggle in the debug layer section\n- dashboard/js/app.js: integrate Fresnel overlay management — create/update/remove ellipsoids on link events\n\n## Tests\n\n- Test ellipsoid geometry computation with known TX/RX positions: TX at (0,0,0), RX at (4,0,0), lambda=0.06m -> a ~= 2.015, b ~= 0.345. Verify to 3 decimal places.\n- Test semi-minor axis for edge case: very short link d=0.1m -> b should be very small but positive\n- Test for diagonal link: TX at (0,0,0), RX at (3,4,0) (distance=5m) -> verify a and b are computed correctly\n- Test that toggling the layer on/off adds/removes the correct number of mesh objects from the scene (mock Three.js scene)\n- Test hover tooltip shows correct data (link health from mock, link endpoints from mock)\n- Test that ellipsoids update when node position changes\n\n## Acceptance Criteria\n\n- Fresnel zone ellipsoids render correctly for all active links when the debug layer is toggled on\n- Ellipsoid semi-major and semi-minor axes match theoretical first Fresnel zone values for the link distance and frequency\n- Toggle shows/hides all ellipsoids cleanly without leaving orphan objects in the scene\n- Hovering an ellipsoid shows the correct tooltip with link details and health score\n- Clicking an ellipsoid selects the corresponding link in the link panel\n- Geometry computation is shared with the explainability overlay via fresnel.js\n- Tests pass","status":"open","priority":3,"issue_type":"task","created_at":"2026-03-28T01:58:33.424914116Z","created_by":"coding","updated_at":"2026-03-28T03:29:14.736776003Z","source_repo":".","compaction_level":0,"original_size":0,"dependencies":[{"issue_id":"spaxel-o0e","depends_on_id":"spaxel-i28","type":"blocks","created_at":"2026-03-28T03:29:14.736620594Z","created_by":"coding","metadata":"{}","thread_id":""}]} {"id":"spaxel-o4l","title":"Bidirectional node protocol","description":"Implement full bidirectional protocol over the existing WebSocket connection.\n\n## Deliverables\n- Registration (hello message with capabilities)\n- Health reporting (heap, WiFi RSSI, uptime, temperature every 10s)\n- BLE scan relay (device list JSON)\n- Role/config push from mothership (TX/RX/passive mode, packet rate)\n- OTA command messages (trigger update, progress tracking)\n- All messages over the existing single WebSocket per node\n\n## Acceptance Criteria\n- Nodes register on connect with full capability advertisement\n- Mothership can push role changes and config updates\n- Health metrics flow reliably at 10s intervals\n- Protocol is backward-compatible with Phase 1 implementation\n\n## References\n- Current protocol: mothership/internal/ingestion/message.go\n- Firmware WebSocket: firmware/main/websocket.c","status":"closed","priority":2,"issue_type":"task","assignee":"spaxel-alpha","created_at":"2026-03-27T01:56:31.632551776Z","created_by":"coding","updated_at":"2026-03-28T01:34:05.644219477Z","closed_at":"2026-03-27T03:14:43.201850105Z","close_reason":"Implemented full bidirectional node protocol.

Time-travel debugging lets you pause the live 3D view, scrub a timeline to any point in that 48-hour window, and replay the 3D scene exactly as it was at that moment. This is the most powerful debugging tool in spaxel: if a false alert fired at 3am, you can replay those 10 minutes and see exactly which links fired, what the blob positions were, and why the alert triggered. Parameter tuning without hardware becomes possible: change the motion threshold slider and immediately see how different the replay result would have been.\n\n## ReplayEngine\n\nNew package: mothership/internal/replay/engine.go\n\nReplayEngine manages the replay lifecycle:\n- state: LIVE, PAUSED, REPLAYING, SEEKING\n- replay_position: current replay timestamp\n- replay_speed: float64 (1.0 = real-time, 5.0 = 5x speed, 0.0 = paused)\n- linked_session_id: the WebSocket session ID of the client requesting replay (each dashboard session has its own replay state)\n\nReplayEngine.Seek(t time.Time): reads the recording buffer to the specified timestamp. Uses the segment file structure from spaxel-tqj: finds the correct segment file for time t, scans forward to the exact frame at t. Target: seek time < 1 second.\n\nReplayEngine.Play(speed float64): starts reading frames from the buffer at the specified speed and feeding them through the signal processing pipeline.\n\n## Replay Processing Pipeline\n\nThe replay pipeline is a copy of the live processing pipeline but with all outputs redirected to \"replay\" namespaced WebSocket messages:\n- \"replay_blob_update\" instead of \"blob_update\"\n- \"replay_track_update\" instead of \"track_update\"\n- \"replay_link_health\" instead of \"link_health\"\n\nThe replay pipeline uses a separate instance of:\n- SignalProcessor (with possibly modified parameters from the tuning sliders)\n- FusionEngine\n- TrackManager\n\nThese are cloned from the live instances at replay start so they inherit the current configuration, then modified by slider values.\n\nThe replay pipeline is self-contained: it does not affect the live pipeline in any way. Live detection continues while replay is active.\n\n## Parameter Tuning During Replay\n\nWhile in replay mode, the dashboard shows a \"Tuning\" panel with sliders for key signal processing parameters:\n- Motion threshold: deltaRMS threshold for motion detection (default from config, range 0.001 to 0.1)\n- Baseline tau: EMA time constant in seconds (default 30s, range 5s to 300s)\n- Fresnel weight sigma: Gaussian sigma for Fresnel zone contribution (default 0.1m, range 0.01m to 0.5m)\n- Minimum confidence for detection: composite minimum confidence before blob is reported (default 0.3)\n\nChanging any slider: the replay engine discards the current replay pipeline state and re-processes from the current replay_position with the new parameters. This takes at most 1-2 seconds for a typical segment (the CSI frames are already on disk; it's fast CPU processing).\n\n\"Apply to Live\" button: copies the currently-active replay parameters to the live configuration and persists them to the mothership config file. The live pipeline picks up the new values within one processing cycle. Requires confirmation modal: \"This will change the live detection configuration. Continue?\"\n\n## Dashboard Controls\n\nEntering replay mode: clicking the \"Pause\" button (or pressing Space) on the live dashboard:\n1. Pauses the live 3D view (3D scene stops updating)\n2. Shows the timeline scrubber: a horizontal bar spanning the 48-hour recording window\n3. Event markers appear on the scrubber at the timestamps of activity timeline events (zone transitions, alerts, etc.)\n4. \"Live\" chip in the dashboard header changes to \"Replay\" chip\n\nTimeline scrubber:\n- Click to seek to any position in the 48-hour window\n- Drag for continuous scrubbing\n- Event markers: small coloured ticks on the scrubber. Clicking a marker seeks to that event and jumps the activity timeline selection to that event row.\n- The current replay position is shown as a draggable thumb with a timestamp tooltip (\"2026-03-27 03:14:22\")\n\nPlayback controls:\n- Play/Pause button (Space key shortcut)\n- Speed selector: 1x, 5x, 10x\n- Step-forward button: advances replay by 1 second\n- \"Back to Live\" button: exits replay mode and resumes live updates\n\nThe 3D scene in replay mode: shows a \"REPLAY\" watermark badge in the top-left corner (so it's clear the view is not live). All live blob and track updates are suppressed while in replay mode (only replay_ prefixed messages update the scene).\n\n## Seek Performance\n\nThe recording buffer (spaxel-tqj) uses 1-hour segment files. To seek to timestamp T:\n1. Identify the correct segment file: {linkID}-{year}-{month}-{day}-{hour}.csi\n2. Binary search within the file: CSI frames are variable-length but each has a 24-byte header with timestamp_us. Scan forward from start of file to the frame nearest T. O(n) but files are ≤ 1 hour = at most 180,000 frames at 50 Hz. At 64-byte average header read, this is < 10MB scan and typically completes in < 200ms.\n3. Buffer a few seconds of frames ahead of T for smooth playback start.\n\nFor all active links: seek all link segment files in parallel (goroutines). Total seek time < 1s.\n\n## Files to Create or Modify\n\n- mothership/internal/replay/engine.go: ReplayEngine, state machine, seek, play, parameter injection\n- mothership/internal/replay/pipeline.go: replay signal processing pipeline (cloned from live)\n- mothership/internal/recording/ (spaxel-tqj): add SeekToTimestamp(t time.Time) method\n- mothership/internal/dashboard/hub.go: replay_ namespaced WebSocket message routing\n- dashboard/js/replay.js: timeline scrubber UI, playback controls, tuning panel\n- mothership/internal/dashboard/routes.go: WebSocket commands for replay control (type: \"replay_seek\", \"replay_play\", \"replay_pause\", \"replay_set_params\")\n\n## Tests\n\n- Test seek: create a mock recording buffer with known frames at known timestamps. Seek to an arbitrary timestamp, verify the returned frame is the closest one to the target.\n- Test that replay pipeline processes frames identically to live pipeline for the same input (regression test with saved CSI data and known expected output blobs)\n- Test parameter slider: change motion_threshold via replay command, verify the replay pipeline uses the new threshold on subsequent frames\n- Test \"Apply to Live\" correctly writes parameter changes to the live config\n- Test that live pipeline output is unaffected while replay is active (isolation test)\n- Test seek performance: 1-hour segment file with 180,000 frames, seek to timestamp in the middle, complete in < 500ms\n\n## Acceptance Criteria\n\n- Seek to any point in 48-hour window completes in < 1 second for all active links\n- Replay produces identical blob positions to original live processing for the same CSI input\n- Parameter sliders re-process the current replay position in < 3 seconds\n- \"Apply to Live\" copies parameters correctly and live detection immediately uses new values\n- Timeline scrubber event markers correctly align with activity timeline events\n- \"Back to Live\" correctly resumes live detection without any stale state\n- Tests pass","status":"open","priority":3,"issue_type":"task","created_at":"2026-03-28T01:56:04.674847447Z","created_by":"coding","updated_at":"2026-03-28T03:29:14.698778779Z","source_repo":".","compaction_level":0,"original_size":0,"dependencies":[{"issue_id":"spaxel-pvz","depends_on_id":"spaxel-i28","type":"blocks","created_at":"2026-03-28T03:29:14.698749622Z","created_by":"coding","metadata":"{}","thread_id":""},{"issue_id":"spaxel-pvz","depends_on_id":"spaxel-tqj","type":"blocks","created_at":"2026-03-28T01:56:07.776160379Z","created_by":"coding","metadata":"{}","thread_id":""}]} {"id":"spaxel-pwf","title":"Self-improving localisation with BLE ground truth","description":"## Background\n\nThe Fresnel zone fusion engine (spaxel-m9a) computes localisation by weighting each link's deltaRMS contribution according to the geometric intersection of candidate voxels with the Fresnel zone ellipsoid. These weights are currently uniform and based purely on geometry. In practice, some links are better at detecting motion in specific parts of the room than others — due to reflection geometry, multipath, furniture layout, and antenna orientation. By using BLE RSSI positions as continuous ground truth (when a person's labelled phone or wearable is visible), we can refine the per-link, per-zone weights to match observed physical reality.\n\n## Self-Improving Mechanism\n\nNew package: mothership/internal/learning/weights.go\n\nWeightLearner runs as a background goroutine. It operates on ground truth samples collected during normal operation.\n\nA ground truth sample is collected when BOTH:\n1. A confident BLE triangulated position is available for a known person (confidence > 0.7 from identity matching bead spaxel-nqh)\n2. A CSI blob position is within 0.5m of the BLE position (confirming the blob corresponds to that person)\n\nSample structure: {timestamp, person_id, ble_position Vec3, blob_position Vec3, per_link_delta_rms map[linkID]float64, per_link_health map[linkID]float64}\n\nThese samples are stored in SQLite: ground_truth_samples (id, timestamp, person_id, position_xyz, per_link_deltas_json, per_link_health_json). The table is capped at 10,000 samples per person (oldest first out) to prevent unbounded growth.\n\n## Online Weight Learning\n\nAfter accumulating 100+ samples for a given spatial zone (the room is divided into zones of 0.5m x 0.5m grid cells for this purpose), run incremental linear regression:\n\nPrediction model: position_estimate = sum_i (w_i * delta_rms_i) / sum_i w_i, where w_i are the learnable per-link weights.\n\nThe objective is to minimise the mean squared error between the position estimate from the weighted fusion and the ground truth BLE positions, over all samples in the zone.\n\nUpdate rule (stochastic gradient descent, online):\nFor each new ground truth sample:\n- Compute current position estimate using current weights\n- Compute error = ground_truth_position - estimated_position\n- For each link i: w_i += learning_rate * error * delta_rms_i / |delta_rms_vector|\n- learning_rate = 0.001 (small to prevent overfitting to transient environmental changes)\n- Apply L2 regularisation: w_i *= (1 - regularisation * learning_rate) where regularisation = 0.01\n\nClip weights to [0, 5] to prevent divergence. Normalise weight vector to unit sum after each update.\n\n## Validation Gate\n\nTo prevent the learned weights from degrading accuracy (overfitting, transient environmental changes, sensor noise):\n\nHold out 20% of samples as a validation set (random selection). After each batch of 50 weight updates, compute the mean position error on the validation set using the updated weights vs. the original (geometric) weights.\n\nOnly persist the updated weights if: validation_error_new < validation_error_original * 0.95 (at least 5% improvement on the validation set).\n\nIf the validation check fails, discard the weight update and log: \"Weight update rejected: no improvement on validation set. Keeping current weights.\"\n\nThis is a conservative gate. The threshold is configurable (fleet.weight_improvement_threshold, default 0.05).\n\n## Weight Storage\n\nSQLite table: link_weights (link_id TEXT, zone_grid_x INT, zone_grid_y INT, weight REAL, sample_count INT, last_updated DATETIME, validation_improvement REAL, PRIMARY KEY (link_id, zone_grid_x, zone_grid_y)).\n\nZone grid: floor is divided into 0.5m cells. zone_grid_x = floor(x / 0.5), zone_grid_y = floor(y / 0.5). This allows position-dependent weights — a link might be excellent for localisation in one area and poor in another.\n\nOn FusionEngine update: instead of using geometric Fresnel zone weights alone, multiply by the learned spatial weight for the voxel being evaluated (bilinear interpolation between grid cells for smooth transitions).\n\nFallback: if no learned weight exists for a grid cell (insufficient samples), use the geometric weight (learned weight = 1.0). This ensures correctness during the learning period.\n\n## Accuracy Trend in Dashboard\n\nThe accuracy improvement from learning should be visible to users. In the \"Accuracy\" dashboard panel (Phase 7 feedback loop bead):\n\nAdd \"Position accuracy\" subsection:\n- Median position error (m): computed weekly from ground truth samples. median(|ble_position - blob_position|) over all weekly samples.\n- Week-over-week trend: sparkline of weekly median position error. Arrow indicating direction (improving/degrading).\n- Sample count: \"Based on N position measurements from M people this week\"\n- \"Accuracy improving\" badge when position error has decreased by > 10% vs previous week.\n\n## Files to Create or Modify\n\n- mothership/internal/learning/weights.go: WeightLearner, SGD update, validation gate\n- mothership/internal/learning/samples.go: ground truth sample collection, SQLite storage\n- mothership/internal/fusion/engine.go (spaxel-m9a): integrate learned weights in FusionEngine\n- mothership/internal/dashboard/routes.go: GET /api/accuracy/weights (debug endpoint showing current weight map)\n- dashboard/js/accuracy.js: position accuracy trend chart\n\n## Tests\n\n- Test ground truth sample collection gates correctly: confidence > 0.7 AND BLE-blob distance < 0.5m -> sample collected; confidence = 0.6 -> no sample\n- Test SGD weight update: after 100 samples with known ground truth, verify weights move in the direction that reduces error\n- Test validation gate: inject a batch of adversarial samples that would degrade accuracy, verify gate rejects the update\n- Test bilinear interpolation between adjacent grid cells produces smooth weight values\n- Test weight fallback: FusionEngine correctly uses geometric weight=1.0 when no learned weight exists for a grid cell\n- Test SQLite cap: inserting 10,001 samples removes the oldest one, maintaining the 10,000 cap\n\n## Acceptance Criteria\n\n- Position error decreases measurably over 2+ weeks of operation with BLE ground truth data (target: from initial ~1.2m to < 0.8m median error)\n- Validation gate prevents weight regressions (mock adversarial samples do not degrade fusion accuracy)\n- Weight updates persist across mothership restarts\n- Position accuracy trend visible in dashboard Accuracy panel\n- Sample collection rate visible (samples per day per person) in dashboard\n- Tests pass","status":"closed","priority":3,"issue_type":"task","assignee":"bravo","created_at":"2026-03-28T01:50:34.214065492Z","created_by":"coding","updated_at":"2026-03-30T00:12:00.715207673Z","closed_at":"2026-03-30T00:12:00.715088959Z","close_reason":"Implemented self-improving localization with BLE ground truth.

OR: stationary detection drops and does not return for > 30 minutes (person left room without portal crossing — reconciliation path)\n\nSession record stored in SQLite:\nCREATE TABLE sleep_sessions (\n id TEXT PRIMARY KEY,\n person_id TEXT NOT NULL,\n zone_id TEXT NOT NULL, -- bedroom zone\n session_date DATE NOT NULL, -- the date this sleep night belongs to (typically today-1 for morning reports)\n sleep_onset DATETIME, -- time tentative detection was confirmed\n wake_time DATETIME,\n time_in_bed_minutes REAL,\n sleep_latency_minutes REAL, -- time from entering bedroom to sleep onset\n wake_episode_count INTEGER DEFAULT 0,\n wake_after_sleep_onset_minutes REAL, -- total time awake after first sleep onset\n breathing_rate_mean REAL,\n breathing_rate_stddev REAL,\n breathing_anomaly_count INTEGER DEFAULT 0, -- breathing < 8 or > 25 per minute\n sleep_efficiency REAL -- (time_in_bed - waso) / time_in_bed * 100\n);\n\nCREATE TABLE sleep_wake_episodes (\n id TEXT PRIMARY KEY,\n session_id TEXT,\n episode_start DATETIME,\n episode_end DATETIME,\n duration_seconds REAL\n);\n\n## Sleep Metrics Computation\n\nDuring the sleep session, SleepMonitor subscribes to:\n- Breathing data: periodic sample of breathing_freq_hz from BreathingDetector (spaxel-r37). Store in a rolling buffer.\n- Motion events: MOTION_DETECTED state transitions from LinkProcessor. Each motion event during a confirmed sleep session is a potential wake episode.\n\nWake episode classification:\n- If deltaRMS > threshold for > 3 seconds: wake episode starts\n- If deltaRMS returns below threshold and breathing signal resumes: wake episode ends\n- Store episode start/end in sleep_wake_episodes\n\nBreathing analysis during sleep:\n- Mean breathing rate (bpm): mean(breathing_freq_hz * 60) over all samples in session\n- Breathing rate standard deviation: indicates sleep stage variability (higher variance may indicate REM activity)\n- Breathing anomaly: if breathing_freq_hz * 60 < 8 or > 25 for > 3 consecutive minutes: log anomaly. This is a proxy for potential sleep apnoea or hyperventilation.\n\nSleep efficiency: (time_in_bed_minutes - wake_after_sleep_onset_minutes) / time_in_bed_minutes * 100. A value above 85% is considered good sleep efficiency.\n\n## Morning Summary Card\n\nOn first WebSocket connection from the dashboard after 6am AND after a sleep session has ended (wake_time is set):\n- Mothership pushes a \"morning_summary\" WebSocket message with the completed session data\n- Dashboard renders a dismissible card in simple mode (full width at top) and as a floating panel in expert mode\n\nCard content:\n- \"Last night: [sleep_duration] h [mm] min\"\n- Colored efficiency indicator: green (>85%), amber (70-85%), red (<70%)\n- Wake episodes: \"2 wake episodes, [total waso] min awake after sleep onset\"\n- Breathing: \"Average breathing: [N] breaths/min\"\n- Anomaly note (if applicable): \"Unusual breathing detected at [time]. [View details]\"\n- \"View full sleep report\" link (opens detailed timeline view in expert mode)\n\n## Weekly Trends\n\nDashboard \"Sleep\" panel:\n- 7-day sparkline of sleep duration per night\n- 7-day sparkline of sleep efficiency per night\n- Average breathing rate over the week\n- Week-over-week comparison: \"This week you slept 6h 48m on average (vs. 7h 12m last week)\"\n\n## Per-Person Tracking\n\nSleep monitoring is person-specific and requires BLE identity (so the system knows whose bedroom this is). Multiple people sharing a bedroom: each person has their own sleep session if their BLE devices can be distinguished. If both people are in bed simultaneously, the breathing detector may pick up a blend of two breathing rates — acknowledge this limitation in documentation.\n\nFor anonymous tracks (no BLE identity): detect in-bedroom stationary presence only (no per-person sleep report). Log \"Unidentified person in bedroom zone\" for 8+ hour periods.\n\n## Zone Configuration\n\nThe zone editor (portals bead, spaxel-qlh) is extended with a zone type selector:\n- Normal zone (default)\n- Bedroom (enables sleep monitoring)\n- Kitchen (no special behavior)\n- Children's zone (suppresses fall detection)\n\nThis is stored as zone_type in the zones table.\n\n## Files to Create or Modify\n\n- mothership/internal/sleep/monitor.go: SleepMonitor, session detection, metric computation\n- mothership/internal/sleep/report.go: morning summary generation, weekly trend aggregation\n- mothership/internal/signal/breathing.go (spaxel-r37): add tick-based sample reporting for sleep monitor\n- dashboard/js/sleep.js: morning summary card, Sleep panel\n- mothership/internal/events/events.go: SleepSessionStartEvent, SleepSessionEndEvent\n\n## Tests\n\n- Test sleep session onset: stationary detection fires, person in bedroom, 15 minutes -> session confirmed\n- Test that stationary detection < 15 minutes does not create a session (avoids brief naps misclassified)\n- Test wake episode counting: 3 MOTION_DETECTED events > 3s each during a session -> wake_episode_count = 3\n- Test wake after sleep onset calculation: 3 episodes of 5 minutes each -> waso = 15 minutes\n- Test sleep efficiency calculation: 480 minutes in bed, 45 minutes waso -> efficiency = 90.6%\n- Test breathing anomaly detection: inject 4 minutes of breathing_freq_hz = 0.1 (6 bpm) -> anomaly logged\n- Test morning summary trigger fires only on first connection after 6am AND after session end\n\n## Acceptance Criteria\n\n- Sleep session detected within 15 minutes of confirmed onset (stationary in bedroom zone)\n- Wake episodes counted correctly (tested with synthetic motion event injection)\n- Morning summary card appears on first dashboard open after wake time (6am by default, configurable)\n- Weekly trends sparkline shows 7 nights of data after 7 days\n- Sleep session data persists in SQLite across mothership restarts\n- Breathing anomaly flag fires correctly for rate < 8 or > 25 bpm\n- Tests pass","status":"in_progress","priority":3,"issue_type":"task","assignee":"delta","created_at":"2026-03-28T01:52:06.457208929Z","created_by":"coding","updated_at":"2026-04-07T19:45:27.613128879Z","source_repo":".","compaction_level":0,"original_size":0,"labels":["deferred"]} {"id":"spaxel-qgj","title":"Implement NTP client in ESP32 firmware","description":"Add NTP synchronization to firmware/main/wifi.c or ntp.c:\n- Call esp_sntp_setservername(0, ntp_server) before esp_sntp_init() on boot\n- ntp_server read from NVS 'ntp_server' key (default: 'pool.ntp.org')\n- Attempt sync for up to 10 seconds after WiFi connect; log WARN if sync fails\n- On sync failure: proceed without stagger (rely on CSMA/CA)\n- Resync every 10 minutes via esp_timer periodic callback\n- Include ntp_synced status in health JSON message\n\nAcceptance: Node health messages show ntp_synced: true when pool is reachable; ntp_synced: false when NTP blocked — node still operates normally; resync occurs every ~600s (verified via UART logs)","status":"closed","priority":2,"issue_type":"task","assignee":"alpha","created_at":"2026-04-07T14:37:00.302557793Z","created_by":"coding","updated_at":"2026-04-07T17:32:57.896842167Z","closed_at":"2026-04-07T17:32:57.896693758Z","close_reason":"done","source_repo":".","compaction_level":0,"original_size":0,"labels":["failure-count:1","mitosis-child","mitosis-depth:1","parent-spaxel-u7y"]} {"id":"spaxel-qlh","title":"Room transition portals and zone occupancy","description":"## Background\n\nKnowing a blob is at coordinates (3.2m, 1.8m, 1.0m) is useful to the algorithm, but \"Alice is in the Kitchen\" is useful to a person. Room transition portals define doorway planes between named zones. When a track's trajectory intersects a portal plane, the zone occupancy counts update and a transition event fires. This is the foundation for natural language presence display (\"Alice is in the Kitchen\"), automation triggers (\"when Alice enters the bedroom\"), and the activity timeline (\"Alice moved from Living Room to Kitchen at 14:23\").\n\n## Zone Definitions\n\nZones are named 3D volumes represented as axis-aligned bounding boxes (AABB) for simplicity. Each zone has: id (uuid), name (\"Kitchen\"), bounds_min (Vec3), bounds_max (Vec3), color (hex string for 3D overlay), created_at.\n\nSQLite schema:\nCREATE TABLE zones (\n id TEXT PRIMARY KEY,\n name TEXT NOT NULL,\n bounds_min_x REAL, bounds_min_y REAL, bounds_min_z REAL,\n bounds_max_x REAL, bounds_max_y REAL, bounds_max_z REAL,\n color TEXT DEFAULT '#3b82f6',\n created_at DATETIME DEFAULT CURRENT_TIMESTAMP\n);\n\nContainment test: a position P is in zone Z if bounds_min_x <= P.x <= bounds_max_x AND bounds_min_y <= P.y <= bounds_max_y. The Z bounds are typically 0 to ceiling height (usually 2.5m) since we track floor-plane position.\n\n## Portal Definitions\n\nA portal is a vertical plane segment spanning a doorway. It divides two zones and detects crossings.\n\nPortal schema:\nCREATE TABLE portals (\n id TEXT PRIMARY KEY,\n name TEXT, -- e.g. \"Kitchen Door\"\n zone_a_id TEXT, -- zone on one side\n zone_b_id TEXT, -- zone on other side\n plane_point Vec3, -- a point on the portal plane (e.g. centre of doorway)\n plane_normal Vec3, -- unit normal vector of the portal plane\n width REAL, -- width of the doorway in metres\n height REAL, -- height of the doorway (default: 2.1m)\n created_at DATETIME\n);\n\nA portal normal points from zone_a toward zone_b. A crossing from zone_a to zone_b has dot(velocity, normal) > 0. A crossing from zone_b to zone_a has dot(velocity, normal) < 0.\n\n## Portal Editor (3D Dashboard)\n\nExtend the node placement UI (spaxel-qq6) with portal editing:\n1. User clicks \"Add Portal\" button\n2. A vertical plane appears in the 3D scene at the camera's focal point\n3. User drags the plane using TransformControls (from Three.js addons) to position it across a doorway\n4. User adjusts width and assigns zone names on each side (dropdown of existing zones or \"Create new zone\")\n5. User clicks \"Save\" — portal is stored in SQLite and rendered as a semi-transparent divider plane in the 3D scene\n\nPortal rendering: thin coloured plane (opacity 0.3, colour #a855f7 purple) with a label at the top edge showing the portal name. When a track crosses the portal, the plane briefly flashes brighter (animated opacity increase then decay back to 0.3).\n\nZone rendering: semi-transparent coloured cuboid volumes (opacity 0.1, colour from zone.color). Zone name displayed as a floating text label at the zone centroid (using THREE.Sprite). A \"Zones\" layer toggle in the 3D view hides/shows all zones simultaneously.\n\n## Crossing Detection\n\nCrossingDetector runs as part of the TrackManager update loop (10 Hz). For each track update:\n\n1. For each active portal, test if the track crossed the portal plane in the last update step:\n - Previous position P_prev, current position P_curr\n - Check if the line segment P_prev -> P_curr intersects the portal plane within the portal's rectangular bounds (width x height centered on plane_point)\n - Intersection test: t = dot(plane_point - P_prev, normal) / dot(P_curr - P_prev, normal). If 0 <= t <= 1, compute intersection point P_int = P_prev + t*(P_curr - P_prev), then check if P_int is within the doorway rectangle.\n - Crossing direction: if dot(P_curr - P_prev, normal) > 0, direction is A_to_B; otherwise B_to_A.\n\n2. On crossing detected: update occupancy counts, emit ZoneCrossingEvent.\n\nZoneCrossingEvent: {portal_id, track_id, person_id, person_label, from_zone_id, from_zone_name, to_zone_id, to_zone_name, direction, timestamp}.\n\nThis event is:\n- Published to the internal event bus\n- Broadcast via WebSocket to dashboard as type \"zone_transition\"\n- Appended to activity timeline (Phase 8)\n- Processed by automation engine (Phase 6)\n\n## Occupancy Counter\n\nOccupancyManager maintains a per-zone current occupant list (map[zoneID][]TrackID).\n\nUpdates from two sources:\n1. CrossingDetector portal events: when a track crosses from zone A to B, move its entry in the occupancy map from A to B.\n2. Direct containment check: run every 30 seconds as a reconciliation pass. For each active track, check if it is within any zone's bounding box. If the track is in zone C but the occupancy map says it is in zone A (e.g. track was created inside a zone without crossing a portal), update accordingly.\nThe containment check prevents \"teleportation\" inconsistencies when tracks are created or resume from coasting state.\n\n## WebSocket Broadcast\n\nOn each zone occupancy change, the mothership broadcasts:\n{\"type\":\"zone_occupancy\",\"zones\":[{\"id\":\"zone-kitchen\",\"name\":\"Kitchen\",\"occupants\":[{\"track_id\":\"track-1\",\"person_id\":\"uuid-alice\",\"person_label\":\"Alice\"}]},{\"id\":\"zone-living\",\"name\":\"Living Room\",\"occupants\":[]}]}\n\nAnd specifically on crossings:\n{\"type\":\"zone_transition\",\"portal_id\":\"...\",\"person_label\":\"Alice\",\"from_zone\":\"Kitchen\",\"to_zone\":\"Living Room\",\"timestamp\":\"2026-03-27T14:23:00Z\"}\n\n## REST API\n\nGET /api/zones: list all zones with current occupancy\nPOST /api/zones: create zone\nPUT /api/zones/{id}: update zone bounds/name/color\nDELETE /api/zones/{id}: delete zone (removes from all occupancy tracking)\n\nGET /api/portals: list all portals\nPOST /api/portals: create portal\nPUT /api/portals/{id}: update portal\nDELETE /api/portals/{id}: delete portal\n\nGET /api/zones/{id}/history?since=2026-03-27T00:00:00Z: get crossing history for zone (list of ZoneCrossingEvent)\n\n## Tests\n\n- Test portal crossing detection with a track path that passes through the portal plane: verify crossing event fires with correct direction\n- Test that a track path that runs parallel to a portal plane but within 0.1m does not fire a false crossing\n- Test that a track path outside the portal's width bounds does not fire a crossing\n- Test occupancy count updates: zone Kitchen starts with 1 occupant, track crosses portal to Living Room, Kitchen count = 0, Living Room count = 1\n- Test the 30-second reconciliation pass: track that appears inside a zone without crossing a portal is correctly assigned to that zone\n- Test zone containment with a position exactly on the bounds_min edge (inclusive boundary)\n- Test that zone_transition WebSocket message is broadcast with correct from_zone and to_zone names\n\n## Acceptance Criteria\n\n- Portal editor allows placing vertical plane portals across doorways in the 3D scene\n- Zone bounding boxes are editable and render as semi-transparent volumes in 3D view\n- Zone labels update in real-time as people move between zones (\"Kitchen: Alice, Bob\")\n- Zone transition events fire within one track update cycle (100ms) of the crossing occurring\n- Reconciliation pass correctly handles tracks that appear inside zones without portal crossings\n- Zone and portal data persists across mothership restarts via SQLite\n- WebSocket broadcasts zone_occupancy after every occupancy change\n- Tests pass","status":"open","priority":3,"issue_type":"task","created_at":"2026-03-28T01:45:41.668543362Z","created_by":"coding","updated_at":"2026-03-28T03:29:14.268105795Z","source_repo":".","compaction_level":0,"original_size":0,"dependencies":[{"issue_id":"spaxel-qlh","depends_on_id":"spaxel-c0q","type":"blocks","created_at":"2026-03-28T03:29:14.268078719Z","created_by":"coding","metadata":"{}","thread_id":""},{"issue_id":"spaxel-qlh","depends_on_id":"spaxel-nqh","type":"blocks","created_at":"2026-03-28T01:45:44.642770328Z","created_by":"coding","metadata":"{}","thread_id":""}]} {"id":"spaxel-qob","title":"Webhook action firing & fault tolerance for automations","description":"## Overview\nReliable webhook delivery for automation trigger actions with error handling and dashboard feedback.\n\n## Backend (mothership/automation/)\n- HTTP client: POST to configured URL with 5s timeout;

The plan specifies server-side rendering of mini floor-plan thumbnails attached to notifications to provide instant spatial context without opening the app.\n\n## Server-Side Floor-Plan Renderer\n\nNew package: mothership/internal/render/floorplan.go\n\nThe renderer produces a top-down 2D PNG (300x300 pixels) showing:\n- Room outline: outer boundary of all zones as white rectangles on dark background\n- Zone fills: each zone as a semi-transparent coloured fill (zone.color at 20% opacity)\n- Zone labels: zone name in small white text at zone centroid\n- Node positions: small white circle dots\n- Person blobs: coloured circles (person.color) at their last-known position, diameter proportional to detection confidence (min 10px, max 20px)\n- Name labels: person name in white text above each blob circle, if identity is known\n- Portal planes: thin lines in purple (#a855f7)\n- Event highlight: the zone where the event occurred rendered with brighter fill and a white border\n\nRendering library: use github.com/fogleman/gg (a pure-Go 2D graphics library). Alternative: standard image/draw + image/png for maximum portability. The fogleman/gg approach is recommended for its higher-level drawing API (bezier curves, text, etc.).\n\nThe PNG must be generated within 200ms to not delay notification delivery. At 300x300 with simple geometry, this should be easily achievable.\n\nThe rendered PNG is stored as a []byte and passed to the notification delivery function. It is base64-encoded for attachment in webhook payloads or passed as a file to ntfy/Pushover APIs.\n\n## Notification Types and Triggers\n\n1. zone_enter: \"{{person_name}} entered {{zone_name}}\" — LOW priority unless security mode is active\n2. zone_leave: \"{{person_name}} left {{zone_name}}\" — LOW priority\n3. zone_vacant: \"{{zone_name}} is now empty\" — LOW priority\n4. fall_detected: \"Possible fall: {{person_name}} in {{zone_name}}\" — URGENT, always immediate\n5. fall_escalation: \"URGENT: Fall unacknowledged for 5 minutes — {{person_name}} in {{zone_name}}\" — URGENT\n6. anomaly_alert: \"Unexpected presence: {{zone_name}}\" — HIGH priority (breaks quiet hours)\n7. node_offline: \"Node {{node_label}} has gone offline\" — MEDIUM priority\n8. sleep_summary: \"Last night: {{sleep_duration}}\" — LOW priority, morning delivery\n\n## Smart Batching\n\nIf multiple LOW or MEDIUM priority events fire within a 30-second window, batch them into a single notification:\n- \"Alice entered Kitchen. Bob left Living Room.\"\n- \"2 presence events in the last 30 seconds.\"\n\nBatching rules:\n- Batch only events of the same priority level\n- Never batch URGENT events — those are always immediate\n- Never batch events involving different notification types if the combination is confusing\n- Batch counter: if more than 5 events in 30s, summarise as \"N presence events in the last minute\"\n\nBatching implementation: a 30-second window timer per notification channel. When the first LOW event fires, start the 30s timer. Accumulate events.

The onboarding wizard is the centrepiece of this experience. It uses the Web Serial API (available in Chrome/Edge) to communicate with the ESP32 over USB — no driver installation needed, no CLI, no app download. The wizard is embedded in the existing mothership dashboard, accessible at /onboard.\n\n## Why Web Serial?\n\nThe alternative approaches — a dedicated mobile app, a WiFi provisioning AP, or a CLI tool — all have significant UX friction. Web Serial lets us flash firmware, provision WiFi credentials, and guide the user through calibration all in one browser session. The dashboard already knows the mothership IP/port. Chrome and Edge (95%+ of desktop browser market) support Web Serial natively since 2021. The only caveat is that Web Serial is not available in Firefox or Safari — this must be documented prominently at the start of the wizard.\n\n## Wizard Steps\n\n1. Browser check: Detect navigator.serial availability. If missing, show: \"Please use Google Chrome or Microsoft Edge to use the setup wizard. Firefox and Safari do not support USB device access.\"\n\n2. Connect device: Call navigator.serial.requestPort(). Guide the user to hold BOOT button while plugging in if the device does not appear. Show a SVG illustration of the ESP32-S3 board with the BOOT button highlighted.\n\n3. Flash firmware (if not already spaxel firmware): Use esp-web-tools (espressif/esp-web-tools). This open-source library handles the full ESP32 flashing pipeline via Web Serial, including ROM bootloader protocol, chip detection, and progress reporting. It needs a firmware manifest.json at GET /api/firmware/manifest describing binary addresses and offsets. Show a progress bar during flashing. Estimated time: 45-90 seconds.\n\n4. Provision WiFi: Show a form for SSID and password. Optional: mothership host/port override (for non-mDNS setups). Assemble the provisioning payload and send to the ESP32 over serial as JSON (see Provisioning Payload bead for format).\n\n5. Detect mothership: Once provisioned and rebooted, the ESP32 boots and discovers the mothership via mDNS (spaxel-mothership.local) or the configured host. Poll GET /api/nodes every 3s for up to 120s waiting for the new node to appear. Show animated \"Connecting...\" indicator. On timeout: show WiFi troubleshooting guidance (5GHz check, SSID typo check, distance check).\n\n6. Guided calibration: Show the CSI waveform for the new node's links as they come online. Steps:\n a. \"Walk around your space for 30 seconds\" — CSI amplitude should show activity. If flat: check node orientation.\n b. \"Stand still at the far end of the room\" — capture baseline. Show countdown. Green check when baseline is captured.\n c. \"Walk through the centre of the room\" — Fresnel zone lights up in 3D view, blob appears. \"The sensor can see you!\"\n\n7. Node placement guidance: Transition to the coverage painting UI (spaxel-qq6) for optimal node positioning. Show GDOP overlay for the current node placement. Suggest additional node positions if coverage is poor.\n\n## Files to Create or Modify\n\n- dashboard/js/onboard.js: wizard state machine, Web Serial API calls, step rendering\n- dashboard/index.html: add /onboard route and wizard container div, import esp-web-tools\n- mothership/internal/dashboard/ routes: add GET /api/firmware/manifest route\n- Firmware manifest JSON served at GET /api/firmware/manifest with chipFamily, parts array containing path and offset\n\n## esp-web-tools Integration\n\nThe library esp-web-tools is loaded from CDN as an ES module. A custom-element install-button is used for flashing. The manifest served by the mothership includes the firmware binary path (/firmware/latest) and flash offset (0x0). The library handles the bootloader handshake, erase, and write automatically.\n\n## Wizard State Machine\n\nStates: BROWSER_CHECK -> CONNECT_DEVICE -> FLASH_FIRMWARE -> PROVISION_WIFI -> DETECT_NODE -> CALIBRATE -> PLACEMENT -> COMPLETE\n\nEach state has: render() function, onEnter() side effects, onNext() transition, onBack() for revert, onError() for failure handling.\n\nPersisted in sessionStorage so a page refresh during onboarding resumes from the last step — critical for the reboot-then-detect step where the browser must survive the ESP32 reboot cycle.\n\n## Error Handling\n\nMap every known failure to a human-friendly message:\n- NotFoundError (no port selected) -> \"No device detected. Make sure the USB cable is connected and hold the BOOT button while plugging in.\"\n- NetworkError during flash -> \"The connection was interrupted. Check the USB cable is not loose and try again.\"\n- Node not appearing after 120s -> \"Your node connected to WiFi but cannot reach the mothership. Check: 1) Your router blocks device-to-device communication (AP isolation). 2) The mothership address is correct. 3) Your network uses a VLAN that separates devices.\"\n- Wrong SSID/password -> Node will fall into captive portal mode after 10 failures, triggering a \"Captive portal detected\" guidance flow.\n\nNever show stack traces, WebSocket error codes, or Go error strings to the user.\n\n## Tests\n\n- Mock navigator.serial API in Jest to test wizard state transitions without real hardware\n- Test that provisioning payload is correctly assembled and sent over the mocked serial port\n- Test that polling GET /api/nodes correctly detects node appearance and transitions to DETECT_NODE -> CALIBRATE\n- Test that BROWSER_CHECK step correctly detects missing serial API and shows the correct error\n- Test that sessionStorage correctly restores wizard state on page refresh at each step\n\n## Acceptance Criteria\n\n- Wizard completes in under 5 minutes on a fresh ESP32-S3 with a working WiFi network\n- User sees live CSI waveform during calibration step\n- Node appears in dashboard after wizard completion, with correct label\n- All known error conditions show human-friendly guidance, not technical errors\n- All existing dashboard tests pass\n- Wizard state is resumable after page refresh","status":"closed","priority":2,"issue_type":"task","assignee":"alpha","created_at":"2026-03-28T01:36:08.928580604Z","created_by":"coding","updated_at":"2026-03-28T08:01:41.237288050Z","closed_at":"2026-03-28T08:01:41.237159218Z","close_reason":"Fixed 4 failing tests in the onboarding wizard test suite:\n\n1.

TextEncoderStream mock: Added functional readable/writable with pipeTo mock and data capture helpers (__getLastEncodedData/__clearLastEncodedData) to support provisioning serial send tests.\n\n3. flash_firmware test: Fixed assertion to check wizard-nav element for 'Skip Flashing' button instead of wizard-content (the nav button is rendered separately from step content).\n\n4. provisionAndSend 'no port' test: Changed getPorts mock from mockResolvedValueOnce to mockResolvedValue([]) so both the primary and fallback provisioning paths consistently fail when no port is available.\n\nAll 60 tests now pass.
