Each BLE relay message contains a list of {mac, name, rssi, manufacturer_data} tuples for all devices heard by that node in the last 5 seconds. Phase 6 turns this raw stream into a structured \"People and Devices\" registry where users can label their devices and associate them with named people. This is the identity layer that transforms anonymous CSI blobs into \"Alice\" and \"Bob\".\n\n## BLE Device Auto-Detection\n\nThe mothership can identify device types from manufacturer data embedded in BLE advertisement packets. The Bluetooth SIG assigns Company IDs to manufacturers; the first 2 bytes of manufacturer_data encode the company ID (little-endian).\n\nCompany IDs to detect:\n- 0x004C (Apple): likely iPhone, iPad, AirPods, or Apple Watch. Sub-type from manufacturer data length and flags.\n- 0x0006 (Microsoft): Windows devices\n- 0x0075 (Samsung): Samsung phones/tablets\n- 0x009E (Fitbit): Fitness trackers\n- 0x0157 (Garmin): GPS watches / fitness devices\n- 0x0059 (Nordic): Tile trackers (Nordic Semiconductor is used by many Tile-like devices)\n- 0x0499 (Ruuvi): Ruuvi temperature/humidity sensors\n- 0x00E0 (Google): Android devices (Nearby Share beacons)\nClassify all others as \"Unknown\". The device name field (if present in the advertisement) provides additional signal.\n\nWearable heuristic: RSSI typically -55 to -75 dBm across multiple nodes with relatively consistent signal (worn close to body). Static devices (speakers, tablets) show higher variance. 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. Body: {\"label\":\"Alice's Phone\",\"device_type\":\"apple_phone\",\"person_id\":\"uuid-123\"}\nDELETE /api/ble/devices/{mac}: archive (not hard delete)\n\nGET /api/people: returns list of People with their associated devices\nPOST /api/people: create person. Body: {\"name\":\"Alice\",\"color\":\"#3b82f6\"}\nPUT /api/people/{id}: update name or color\nDELETE /api/people/{id}: soft-delete (retain historical data)\n\n## Dashboard Panel\n\n\"People and Devices\" sidebar panel showing:\n- People section: list of defined people with avatar (initials in circle with their color), device count, last seen time\n - Per person: click to expand, shows associated devices\n - \"Add person\" button opens inline form\n- All devices section (below people): list of devices not yet assigned to a person\n - Per device: device type icon (Apple logo, Fitbit icon, etc.), last seen node (abbreviated), last seen timestamp, RSSI bar\n - Inline label edit on double-click\n - Drag-and-drop to assign to a person card\n - Archive button (hides from active list, accessible via \"Show archived\" toggle)\n- Privacy notice: \"Phones may appear multiple times due to address rotation. Wearables and AirTags have stable addresses.\"\n\n## Tests\n\n- Test device auto-detection: Apple company ID 0x004C -> device_type \"apple_phone\", Fitbit 0x009E -> \"fitbit\"\n- Test that ProcessRelayMessage correctly upserts devices and updates last_seen and RSSI stats\n- Test ArchiveStale marks devices not seen for > 7 days as archived\n- Test person creation and device-to-person assignment API calls\n- Test MAC randomisation handling: two devices with same name and no simultaneous sighting are flagged as possible duplicates\n- Test that archived devices are excluded from GetDevices(false) but included in GetDevices(true)\n\n## Acceptance Criteria\n\n- Discovered BLE devices appear in the dashboard \"People and Devices\" panel within 30 seconds of first observation\n- Device type is auto-detected correctly for Apple, Fitbit, Garmin, and Samsung devices\n- User can assign labels and associate devices with named people via the dashboard UI\n- Drag-and-drop device-to-person assignment works in the UI\n- Devices not seen for > 7 days are automatically archived and hidden from the active list\n- Privacy limitation is clearly documented in the panel UI\n- Possible duplicate MAC-rotated devices are surfaced as merge suggestions\n- Tests pass","status":"closed","priority":3,"issue_type":"task","assignee":"juliet","created_at":"2026-03-28T01:44:02.204633291Z","created_by":"coding","updated_at":"2026-03-29T18:07:39.656772405Z","closed_at":"2026-03-29T18:07:39.656662663Z","close_reason":"done","source_repo":".","compaction_level":0,"original_size":0,"labels":["deferred"],"dependencies":[{"issue_id":"spaxel-2wg","depends_on_id":"spaxel-c0q","type":"blocks","created_at":"2026-03-28T03:29:14.172209347Z","created_by":"coding","metadata":"{}","thread_id":""}]} {"id":"spaxel-32o","title":"Link weather diagnostics and repositioning advice","description":"## Background\n\nEven with good hardware and correct placement, some links will chronically underperform. 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-3ca","title":"Add time-travel debugging","description":"Implement:\n- Pause live mode\n- Timeline scrubbing\n- Replay 3D from recorded CSI data\n\nAcceptance: Can replay 24 hours of historical data with full 3D visualization.","status":"in_progress","priority":2,"issue_type":"task","assignee":"golf","created_at":"2026-04-09T14:54:38.737598265Z","created_by":"coding","updated_at":"2026-04-09T15:43:01.127126316Z","source_repo":".","compaction_level":0,"original_size":0,"labels":["failure-count:5","mitosis-child","mitosis-depth:1","parent-spaxel-sl2"]} +{"id":"spaxel-3ca","title":"Add time-travel debugging","description":"Implement:\n- Pause live mode\n- Timeline scrubbing\n- Replay 3D from recorded CSI data\n\nAcceptance: Can replay 24 hours of historical data with full 3D visualization.","status":"in_progress","priority":2,"issue_type":"task","assignee":"golf","created_at":"2026-04-09T14:54:38.737598265Z","created_by":"coding","updated_at":"2026-04-09T16:48:07.695081401Z","source_repo":".","compaction_level":0,"original_size":0,"labels":["failure-count:14","mitosis-child","mitosis-depth:1","parent-spaxel-sl2"]} {"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).

ESP-IDF has a mature OTA (Over-The-Air) update mechanism: two OTA flash partitions (factory, ota_0, ota_1 as defined in firmware/partitions.csv), HTTP download to the inactive partition, cryptographic verification, set boot partition, reboot. The mothership serves firmware binaries and triggers the update via a WebSocket downstream command. Phase 1 laid the groundwork in the firmware; this bead completes the mothership side.\n\n## What Already Exists\n\nfirmware/main/websocket.c has OTA command handling and an ota_download_task that handles the HTTP download to the inactive OTA partition. The partition table in firmware/partitions.csv has factory + ota_0 + ota_1 slots. The firmware parses {type:\"ota\", url:\"...\", md5:\"...\", version:\"...\"} downstream commands and initiates the download. What is missing is:\n- The mothership HTTP server for firmware binary serving\n- The REST API for triggering OTA per-node or fleet-wide\n- The firmware manifest for version management\n- The rollback detection logic on the mothership side\n- The dashboard UI for OTA management\n\n## Mothership Firmware Serving\n\nGET /firmware/latest or GET /firmware/{version}: serves the compiled .bin file from the /firmware volume mount. The response must include:\n- Content-Length header (required by ESP-IDF OTA HTTP client for progress reporting)\n- ETag header (MD5 of the binary, for caching)\n- Content-Type: application/octet-stream\n\nFirmware binaries are placed in the /firmware volume mount (configured in docker-compose.yml or k8s volume mount). The mothership reads the firmware manifest on startup and re-reads it when a new file appears (inotify watch or periodic re-scan every 60s).\n\n## Firmware Manifest\n\nFile: /firmware/manifest.json — auto-generated by the CI build process, or manually created.\nFormat: list of objects, each with version (semver string), filename (basename within /firmware/), md5 (hex string of binary MD5), size (integer bytes), build_timestamp (ISO8601).\nThe mothership's \"latest\" version is determined by sorting manifest entries by semver and taking the highest.\n\n## OTA Trigger API\n\nPOST /api/nodes/{mac}/ota — trigger OTA for a specific node\nRequest body: {\"version\": \"0.2.0\"} (optional; defaults to latest if omitted)\nResponse: {\"job_id\": \"abc123\", \"node_mac\": \"aa:bb:cc:dd:ee:ff\", \"target_version\": \"0.2.0\", \"status\": \"initiated\"}\n\nThe mothership looks up the node's active WebSocket session in the connection registry and sends the OTA command:\n{\"type\":\"ota\",\"url\":\"http://{mothership_ip}:{port}/firmware/0.2.0\",\"md5\":\"{hex_md5}\",\"version\":\"0.2.0\"}\n\nThe firmware immediately begins the download in a background task, sends ota_status messages ({\"type\":\"ota_status\",\"progress\":45,\"status\":\"downloading\"}) which the mothership logs and broadcasts to the dashboard.\n\n## Fleet Rolling Update\n\nPOST /api/ota/fleet — trigger OTA for all connected nodes\nRequest body: {\"version\": \"0.2.0\", \"stagger_seconds\": 30} (default stagger: 30s)\n\nThe rolling update coordinator in the mothership triggers OTA for the first node, waits stagger_seconds, then the next, and so on. This ensures:\n- Not all nodes reboot simultaneously (avoids a coverage gap window)\n- If a node fails OTA, the remaining nodes can be halted before more disruption\n- Fleet update progress is visible in dashboard per-node\n\nThe fleet update job is stored in SQLite (ota_jobs table) and survives mothership restarts.\n\n## Rollback Detection\n\nESP-IDF automatically rolls back to the previous firmware if the new image does not call esp_ota_mark_app_valid_cancel_rollback() within a boot window (the firmware does this on successful WebSocket connection to the mothership). The mothership detects rollback by comparing the firmware_version field in the hello message after OTA against the requested target version. If they differ, the mothership logs an OTA rollback event and updates the node's status to \"rollback\".\n\n## Dashboard OTA UI\n\nAdd an OTA panel to the dashboard settings or fleet page:\n- Per-node: current firmware version, available version (if newer), \"Update\" button\n- Fleet: \"Update All\" button with stagger slider, progress per node (with percentage from ota_status messages), last updated time per node\n- Version history: per-node firmware version history in tooltip or expandable row\n- Rollback indicator: nodes that rolled back are highlighted with a warning and the reason (if known)\n\n## Files to Create or Modify\n\n- mothership/internal/ota/server.go: firmware file serving with Content-Length and ETag\n- mothership/internal/ota/manifest.go: manifest parsing and latest-version logic\n- mothership/internal/ota/jobs.go: OTA job creation, fleet rolling update coordinator, status tracking\n- mothership/internal/dashboard/routes.go: register OTA API routes\n- dashboard/js/fleet.js or dashboard/js/ota.js: OTA UI panel\n\n## Tests\n\n- Test OTA command JSON serialisation matches firmware's expected format exactly\n- Test rolling update stagger timing with a mock time source (use a clock interface for testability)\n- Test that firmware version in hello message is parsed and stored in the node registry\n- Test manifest parsing: valid manifest, empty manifest, malformed manifest\n- Test rollback detection when hello version does not match target version\n\n## Acceptance Criteria\n\n- OTA command reaches firmware and triggers download (verified via ota_status messages)\n- Rolling update staggers correctly with the configured delay between nodes\n- After successful OTA, node reconnects with new firmware version in hello message\n- Rollback is detectable via hello version mismatch and displayed in dashboard\n- MD5 verification failure in firmware logs an error and the old firmware remains running\n- Fleet update status visible per-node in dashboard\n- Tests pass","status":"closed","priority":2,"issue_type":"task","created_at":"2026-03-28T01:37:32.472078279Z","created_by":"coding","updated_at":"2026-03-28T05:36:39.250035631Z","closed_at":"2026-03-28T05:36:39.249972673Z","close_reason":"Implemented: ota/manager.go + ota/server.go (fb69190) — HTTP firmware serving from /firmware volume, WebSocket-triggered OTA command, rolling update with 30s stagger, MD5 verification, firmware manifest.json, rollback detection via hello version mismatch","source_repo":".","compaction_level":0,"original_size":0,"dependencies":[{"issue_id":"spaxel-51k","depends_on_id":"spaxel-uc9","type":"blocks","created_at":"2026-03-28T03:29:13.874999678Z","created_by":"coding","metadata":"{}","thread_id":""}]} {"id":"spaxel-54i","title":"load-shedding: add per-iteration timing and rolling avg to ProcessorManager","description":"## Task\nAdd pipeline timing and a 5-iteration rolling average to `ProcessorManager` in `mothership/internal/signal/processor.go`.\n\n## Changes to ProcessorManager struct (lines 221-228)\nAdd these fields:\n```go\ntype ProcessorManager struct {\n // ... existing fields ...\n iterDurations [5]time.Duration // ring buffer for last 5 iteration times\n iterIdx int // next write index (mod 5)\n iterCount int // how many values filled (0-5)\n shedLevel int // current load shedding level (0-3)\n steadyCount int // consecutive iters below recovery threshold\n}\n```\n\n## Changes to LinkProcessor.Process() (line 54)\nWrap the entire Process body to time it.

The ambient mode is designed for exactly this use case: always on, minimal information density, visually calm, and unobtrusive. It should run for weeks without user interaction, surviving screen timeouts, browser updates, and mothership restarts. When something important happens (fall, security alert), it breaks the calm decisively to get attention.\n\n## Route and Renderer\n\nNew route: /ambient (separate from /simple and expert mode)\nThe user can set a specific device as \"ambient display\" via a browser bookmark or home screen shortcut.\n\nCanvas 2D renderer (not Three.js): the ambient mode uses a dedicated Canvas 2D rendering engine rather than Three.js. Reasons:\n1. Three.js is designed for 3D; the ambient view is a 2D top-down floor plan\n2. Canvas 2D uses significantly less GPU memory and power — important for always-on tablet use\n3. Simpler code path means fewer failure modes for long-running display\n4. Lower battery drain on iPad and Android tablets\n\nRenderer: dashboard/js/ambient_renderer.js. Renders via requestAnimationFrame at 2 Hz (one frame every 500ms). The 2 Hz update rate is intentional: it's visually smooth enough for a presence display and uses minimal CPU.\n\n## Rendered Elements\n\nBackground: colour depends on time of day (see Time-of-Day Palette below).\n\nRoom outline: 2D rectangles for each zone's bounding box (projected to floor plane). White (#ffffff) with 1px stroke, no fill (transparent interior). Zone labels: zone name in white text at centroid, 14px medium font.\n\nPortal lines: thin lines (0.5px, #a855f7 purple) across doorways.\n\nNode positions: small filled circles (radius 4px, #6b7280 grey, subtle).\n\nPerson blobs: filled circles (radius 10-18px) in person.color. Name label above: first name only, 12px white. Blob radius proportional to identity confidence: full size if confident, slightly smaller if low confidence. If anonymous: a ghost/outline circle (stroke only, no fill) in light grey.\n\nSystem status indicator: top-left corner. Small circle (8px radius): green (#22c55e) if all nodes healthy, amber (#f59e0b) if any node degraded, red (#ef4444) if any node offline. No text — just the dot. Tooltip on hover (for the rare touch-and-hold interaction).\n\nTime display: top-right. Current time in large readable font. 28px, #ffffff, tabular-nums font variant for clean time display without layout shifts.\n\nPerson positions: lerp-interpolated between WebSocket updates for smooth movement at the 2 Hz render rate. On each WebSocket message received, update the target position. On each render frame, move each person blob 20% of the remaining distance to the target position (exponential approach = naturally decelerating animation).\n\n## Auto-Dim\n\nWhen no person is detected in the room where the ambient tablet is physically located (a zone that the user has configured as the \"ambient display zone\"), reduce the canvas brightness after 60 seconds of no detection:\n- After 60s: reduce canvas globalAlpha to 0.4 (40% brightness)\n- Restore immediately when presence detected in the ambient zone again\n\nImplementation: Use the CSS filter brightness() property on the canvas element, animated with a CSS transition. Set `canvas.style.filter = 'brightness(0.4)'` after timeout. This approach correctly dims including text labels.\n\nOptionally: if the device supports it (iOS WKWebView + Power Saving APIs), the ambient mode can request Screen Wake Lock API to prevent the tablet display from sleeping. window.navigator.wakeLock.request('screen'). Re-request on visibility change (the lock is released when the page is hidden).\n\n## Alert Mode\n\nWhen a fall or security alert fires (FallDetected or AnomalyDetected event received via WebSocket):\n1. The Canvas render loop detects the alert event\n2. Full canvas background fades to #dc2626 (urgent red) over 500ms\n3. Large white text in the centre: \"FALL DETECTED — Alice\" or \"ALERT — Motion while away\"\n4. Pulsing animation: canvas background alternates between #dc2626 and #991b1b at 1 Hz\n5. Acknowledge button rendered as a large white rectangle in the centre below the text\n6. Tap/click on the acknowledge button: POST /api/fall/{id}/acknowledge or /api/anomalies/{id}/acknowledge. Returns to normal ambient mode.\n\nThis alert mode must be clearly visible from across the room — the text should be at least 48px on a typical 10-inch tablet.\n\n## Morning Briefing Overlay\n\nFirst time presence is detected after 6am (configurable): the ambient display shows a brief overlay card for 15 seconds:\n- Overlaid on the normal floor plan (dark semi-transparent background)\n- Sleep summary (if available): \"Alice: 7h 23m, good sleep\"\n- Today's expected departures (from presence prediction, Phase 7): \"Alice likely leaves at 8:30am\"\n- System status: \"4 nodes healthy\"\n\nAfter 15 seconds: fade out and return to normal ambient view. Tapping the overlay dismisses it immediately.\n\n## Time-of-Day Palette\n\nThe ambient canvas background colour shifts with the time of day to be visually appropriate:\n- 06:00-12:00 (morning): light blue-grey (#f0f4f8, near white) — cool morning light feel\n- 12:00-18:00 (afternoon): neutral grey (#1e293b, dark) — reduces eye strain in bright rooms\n- 18:00-22:00 (evening): warm amber-grey (#1c1507, very dark warm) — matches evening lighting\n- 22:00-06:00 (night): near black (#040404) — OLED-friendly, minimal light\n\nTransitions: smooth CSS gradient transition over 30 minutes at each boundary (not instant). Implemented by pre-computing the target colour for the next 30 minutes and using CSS linear-gradient + keyframe animation.\n\n## Performance\n\nTarget: < 5% CPU usage on a 2016-era iPad (A9 chip). Achieved by:\n- 2 Hz render rate instead of 60 Hz (30x reduction in GPU/CPU work)\n- No Three.js, WebGL, or shader compilation overhead\n- Canvas 2D is hardware accelerated but lightweight\n- Blob count in a home is typically 1-4 — trivial to render\n\nMemory: the ambient page should have < 50MB JS heap.

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. The old token is invalidated immediately. The new config_blob is sent via the existing WebSocket connection (if online) or over serial (if physically accessible). This handles: WiFi password changes, mothership IP changes, node relabelling.\n\n## Tests\n\n- Test that POST /api/provision returns valid config_blob containing all required NVS keys\n- Test that node_id is unique and increments correctly\n- Test that token validation rejects connections with unknown tokens\n- Test that token validation rejects connections with expired/rotated tokens\n- Test NVS serialisation round-trip: parse config_blob back to NVS key-value map and verify all values\n- Test that a second provision for the same MAC updates rather than duplicates the record\n\n## Acceptance Criteria\n\n- Provisioned node connects to mothership successfully with the assigned node_id and token\n- Token validation correctly rejects unprovisioned connection attempts with {type:\"reject\"}\n- Node label stored and returned via GET /api/nodes in the node list\n- Re-provisioning updates token and invalidates old token within one round-trip\n- config_blob contains all required NVS keys with correct types\n- Tests pass","status":"closed","priority":2,"issue_type":"task","created_at":"2026-03-28T01:36:54.067220841Z","created_by":"coding","updated_at":"2026-03-28T05:36:39.268631627Z","closed_at":"2026-03-28T05:36:39.268468107Z","close_reason":"Implemented: provisioning/server.go (fb69190) + firmware/main/provision.c/h (fb69190) — POST /api/provision generates node_id+token+config_blob, UART serial provisioning window on ESP32, NVS write, provisioned_nodes SQLite table with token validation","source_repo":".","compaction_level":0,"original_size":0,"dependencies":[{"issue_id":"spaxel-72t","depends_on_id":"spaxel-uc9","type":"blocks","created_at":"2026-03-28T03:29:13.844135515Z","created_by":"coding","metadata":"{}","thread_id":""}]} {"id":"spaxel-783","title":"Add Identify button to fleet status page","description":"Add 'Identify' button per row in the fleet status page that POSTs to /api/nodes/{mac}/identify.\n\n**Acceptance:**\n- Fleet status page has 'Identify' button per row","status":"closed","priority":2,"issue_type":"task","assignee":"hotel","created_at":"2026-04-09T11:11:49.991341754Z","created_by":"coding","updated_at":"2026-04-09T11:18:10.966551629Z","closed_at":"2026-04-09T11:18:10.966448973Z","close_reason":"Added Identify button (⚡) per row in the fleet status page that POSTs to /api/nodes/{mac}/identify.

Approximately 1 in 4 adults over 65 fall each year, and a fall without prompt help can be fatal. A system that detects falls without requiring the person to press a button (wearable panic buttons are often not worn consistently) can be life-saving.\n\nA CSI-based fall detector works by analysing the track's Z-position history from the biomechanical blob tracker (spaxel-n9n). A fall is characterised by: rapid Z-axis descent (person goes from standing height ~1.7m to floor level ~0.2m in less than 1 second) followed by sustained stillness (no motion for > 30 seconds at floor level). False positives — sitting down quickly, a child lying on the floor, someone doing yoga — must be minimised through careful gating and the post-fall confirmation step.\n\n## Fall Detection Algorithm\n\nImplemented in mothership/internal/tracker/fall.go or as a method on TrackManager.\n\nState machine per track:\n- NORMAL: no fall detected\n- DESCENT_DETECTED: Z velocity trigger fired, monitoring for confirmation\n- FALL_CONFIRMED: post-fall stillness confirmed, alert active\n- ALERT_ACKNOWLEDGED: user acknowledged, monitoring continues\n\nStep 1 — Descent trigger:\nMonitor Z position history over a 200ms rolling window.

Check that current Z position is < 0.4m (person is at floor level, not just crouching)\nb. Check that motion (deltaRMS from the contributing links) is < 0.01 for > 30 consecutive seconds\nIf both conditions are met: transition to FALL_CONFIRMED, fire alert chain.\nIf Z rises above 0.4m within the 30-second window (person got up): cancel, return to NORMAL.\n\nStep 3 — False positive suppression:\nApply a higher threshold (drop > 1.2m instead of 0.8m) if the track has a \"sitting\" or \"lying\" posture classification in the last 10 minutes (from posture hints in spaxel-n9n). This reduces false alarms for people who sit down quickly or lie down intentionally.\nApply no fall detection in user-defined \"children's zones\" (zones with the is_children_zone flag) where floor-level activity is normal.\n\n## Alert Chain\n\n1. T+0s: FALL_CONFIRMED transition fires.\n Dashboard: full-width banner with high urgency styling. \"Possible fall detected — [person name] in [zone name]. Are you OK? [Acknowledge] [Call for help]\"\n Browser notification API (if permission granted): \"Spaxel: Possible fall detected — Alice in Hallway\"\n\n2. T+2 minutes (without user acknowledgement):\n Webhook/MQTT alert fires (via AutomationEngine with trigger type \"fall_detected\").\n Push notification via configured channel (ntfy/Pushover).\n\n3. T+5 minutes (without acknowledgement):\n Escalation: second webhook fires to any configured escalation URL (separate from primary webhook). Push notification with \"URGENT\" prefix. Dashboard banner pulses red.\n\nAcknowledgement: the [Acknowledge] button on the dashboard banner:\n- Transitions state to ALERT_ACKNOWLEDGED\n- Cancels the T+2min and T+5min timers\n- Logs the acknowledgement in the activity timeline with timestamp\n- Shows a brief form: \"How is [person name]?\" — [Fine, just fell] / [Needed help] / [False alarm]\n- Feedback stored for accuracy tracking (Phase 7)\n\n## Person Identification in Alerts\n\nIf the track has a confirmed BLE identity:\n- Alert: \"Possible fall detected — Alice in Hallway\"\n- Notification: includes person name and zone\n\nIf the track is anonymous:\n- Alert: \"Possible fall detected — unknown person in Hallway\"\n- Fall event still fires and escalates on the same timeline\n\n## Children's Zones\n\nAdd is_children_zone boolean flag to the zones table (see portals bead). A zone marked as children's zone suppresses fall detection for all tracks within it. Set via zone editor in the dashboard. Rationale: young children spend significant time at floor level (crawling, playing), and false fall alerts in a nursery or playroom are highly counterproductive.\n\n## Z Position Accuracy Dependency\n\nFall detection quality is directly tied to the accuracy of 3D position estimates from the tracker (spaxel-n9n). The UKF state includes Z position, but Z is the hardest axis to localise with WiFi CSI — the nodes are typically all at similar heights (wall-mounted or tabletop), so the vertical Fresnel zone geometry is poor. In practice:\n- Z accuracy is typically ±0.3m for direct LoS links\n- Fall detection requires a Z drop of > 0.8m, which should be detectable even with ±0.3m Z error\n- The 30-second stillness confirmation is the primary false-positive filter — it tolerates poor Z accuracy\n\nDocument this in the dashboard: \"Fall detection works best with nodes at different heights (e.g. one high, one low). Single-level node deployment may miss smaller Z changes.\"\n\n## Integration with Existing Systems\n\nFallDetector subscribes to TrackManager updates (the same 10 Hz update loop as identity matching). It receives the full TrackState including position history and posture hints.\n\nFallDetector emits FallEvent to the internal event bus on FALL_CONFIRMED. The event bus (Phase 8 activity timeline bead) logs it to the timeline. The AutomationEngine processes it for automation triggers. The spatial context notifications module (Phase 6) sends the push notification.\n\n## Files to Create or Modify\n\n- mothership/internal/tracker/fall.go: FallDetector struct, state machine, descent/stillness detection\n- mothership/internal/tracker/manager.go: integrate FallDetector in update loop\n- mothership/internal/events/events.go: FallEvent type\n- dashboard/js/fall.js: fall alert banner, acknowledgement handler, escalation countdown\n- mothership/internal/dashboard/routes.go: POST /api/fall/{event_id}/acknowledge\n\n## Tests\n\n- Test descent trigger: inject synthetic track with Z velocity = -2.0 m/s over 500ms and drop from 1.7m to 0.2m. Verify DESCENT_DETECTED transition.\n- Test post-fall confirmation: after descent trigger, inject 30 seconds of deltaRMS < 0.005 at Z = 0.2m. Verify FALL_CONFIRMED transition.\n- Test that a quick sit-down (Z drops from 1.7m to 0.5m at -1.0 m/s — below speed threshold) does NOT trigger DESCENT_DETECTED.\n- Test false positive suppression: track has \"sitting\" posture history, then fall of 0.9m fires — verify higher threshold (1.2m) is applied and no trigger for 0.9m drop.\n- Test alert chain timing: verify T+2min and T+5min timers fire without acknowledgement.\n- Test that acknowledgement cancels pending timers.\n- Test that children's zone flag suppresses fall detection.\n\n## Acceptance Criteria\n\n- Fall detector transitions to FALL_CONFIRMED on a simulated fall trajectory (2.0 m/s descent, 1.5m drop, 30s floor stillness)\n- Post-fall stillness confirmation fires after 30 consecutive seconds of stillness at Z < 0.4m\n- False positive suppression reduces alerts for quick sit-down actions (drop < 0.8m or speed < 1.5 m/s)\n- Alert chain fires at T+0, T+2min, T+5min without acknowledgement\n- Acknowledgement correctly cancels pending escalation timers\n- Person name included in alert when BLE identity is confirmed\n- Children's zone flag suppresses all fall detection for tracks within that zone\n- Tests pass","status":"closed","priority":3,"issue_type":"task","assignee":"juliet","created_at":"2026-03-28T01:47:29.093424440Z","created_by":"coding","updated_at":"2026-03-29T18:07:39.730764084Z","closed_at":"2026-03-29T18:07:39.730401434Z","close_reason":"done","source_repo":".","compaction_level":0,"original_size":0,"dependencies":[{"issue_id":"spaxel-c1c","depends_on_id":"spaxel-c0q","type":"blocks","created_at":"2026-03-28T03:29:14.322493912Z","created_by":"coding","metadata":"{}","thread_id":""},{"issue_id":"spaxel-c1c","depends_on_id":"spaxel-n9n","type":"blocks","created_at":"2026-03-28T01:47:33.774431809Z","created_by":"coding","metadata":"{}","thread_id":""}]} {"id":"spaxel-c41","title":"Bidirectional node protocol","description":"## Background\n\nPhase 1 established the WebSocket connection and binary/JSON frame parsing. Phase 3 requires a richer downstream command set for multi-node coordination. The firmware (firmware/main/websocket.c) already parses these commands — what's missing is the mothership sending them in response to real events.\n\n## What Already Exists\n- mothership/internal/ingestion/message.go: hello, health, ble, ota_status, motion_hint message types parsed\n- mothership/internal/ingestion/server.go: handles incoming messages, sends initial role and config on connect\n- firmware/main/websocket.c: parses role, config, ota, reboot, identify, reject downstream commands\n\n## What to Implement\n\n### 1. NodeSession abstraction\nCreate mothership/internal/ingestion/session.go: NodeSession struct wrapping a WebSocket connection. Methods: SendRole(role string), SendConfig(sampleRate int, passiveBSSID string), SendOTA(url, md5, version string), SendReboot(), SendIdentify() (triggers LED blink). NodeSession is stored in a registry keyed by nodeMAC.\n\n### 2. Role push after hello\nOn receiving a hello message, look up the node's assigned role from the fleet manager (spaxel-8u3). If fleet manager not yet wired (Phase 3 in progress), default to 'rx'. Send role command immediately after hello processing.\n\n### 3. Config push\nAfter role push, send config: {type:'config', sample_rate:20, passive_bssid:'' (if passive role, populated from fleet manager)}. This replaces the hardcoded config send in the current server.go.\n\n### 4. OTA trigger\nPOST /api/nodes/{mac}/ota already planned (OTA bead). Wire NodeSession.SendOTA() to be callable from the fleet/OTA HTTP handler.\n\n### 5. BLE relay to identity service\nOn receiving a ble message, forward BLE device list to a BLERegistry stub (Phase 6). For now, log at INFO level with structured fields: node_mac, device_count, devices[].\n\n### 6. NodeSession registry\nmothership/internal/ingestion/registry.go: thread-safe map[string]*NodeSession. On node disconnect (WebSocket close), remove from registry. Expose: Register(mac, session), Get(mac) (*NodeSession, bool), All() []*NodeSession.\n\n## Key Files\n- mothership/internal/ingestion/server.go — main handler to refactor\n- mothership/internal/ingestion/message.go — message type reference\n- firmware/main/websocket.c — firmware-side command parsing (read-only reference)\n\n## Acceptance Criteria\n- Node receives role push within 100ms of hello\n- Config push follows role push with correct sample_rate\n- NodeSession registry correctly tracks connected nodes\n- NodeSession.Get(mac) returns nil for disconnected node\n- BLE messages logged at INFO with correct fields\n- go test ./internal/ingestion/... passes","status":"closed","priority":2,"issue_type":"task","created_at":"2026-03-28T03:30:50.333442376Z","created_by":"coding","updated_at":"2026-03-28T05:36:26.164722333Z","closed_at":"2026-03-28T05:36:26.164648947Z","close_reason":"Implemented: ingestion/server.go + ratecontrol.go (bcfd1e3) — role/config/OTA push within 100ms of hello, NodeSession abstraction, firmware websocket.c+csi.c dynamic rate","source_repo":".","compaction_level":0,"original_size":0,"dependencies":[{"issue_id":"spaxel-c41","depends_on_id":"spaxel-cxm","type":"blocks","created_at":"2026-03-28T03:30:50.333442376Z","created_by":"coding","metadata":"{}","thread_id":""}]} +{"id":"spaxel-cha","title":"Define virtual space structure","description":"Create the virtual space definition for the simulator.\n\nAcceptance:\n- Virtual space structure is defined with appropriate boundaries and coordinate system\n- Can be instantiated and queried","status":"closed","priority":2,"issue_type":"task","assignee":"hotel","created_at":"2026-04-09T16:11:25.420362924Z","created_by":"coding","updated_at":"2026-04-09T16:43:35.767763066Z","closed_at":"2026-04-09T16:43:35.767706151Z","close_reason":"done","source_repo":".","compaction_level":0,"original_size":0,"labels":["mitosis-child","mitosis-depth:1","parent-spaxel-d41"]} {"id":"spaxel-ciu","title":"Trigger spaxel CI build and verify ardenone-cluster deployment","description":"## Problem\n\nThe spaxel deployment on ardenone-cluster has been stuck in ErrImagePull for 4+ days:\n\n Pod: spaxel-7998b64b7b-ff2qd (namespace: spaxel)\n Error: docker.io/ronaldraygun/spaxel:0.1.0: not found\n\nThe image has never been built/pushed to Docker Hub.

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.

Stored in SQLite notifications_config (channel, quiet_from, quiet_to, quiet_days_bitmask).\n\nDuring quiet hours:\n- LOW priority notifications are queued\n- MEDIUM priority notifications are queued\n- HIGH and URGENT notifications are delivered immediately regardless of quiet hours\n\nAt the end of quiet hours (07:00 on non-override days): deliver all queued notifications as a morning digest bundle: \"While you were asleep: [summary of queued events]\"\n\n## Delivery Channels\n\nntfy:\n- POST to https://ntfy.sh/{topic} (or self-hosted server URL)\n- Headers: Authorization: Bearer {token} (if configured), Priority: urgent/high/default/low/min\n- Body: the notification text\n- Headers: Attach: {base64_encoded_png_url} — for ntfy, attach the floor-plan as a URL if mothership is publicly accessible, or send as base64 data URL for local deployments\n\nPushover:\n- POST to https://api.pushover.net/1/messages.json\n- Fields: token, user, message, title, priority, attachment (PNG as multipart form upload)\n\nGeneric webhook:\n- POST to user-configured URL\n- Body: {\"event_type\":\"...\", \"message\":\"...\", \"person_id\":\"...\", \"zone_id\":\"...\", \"timestamp\":\"...\", \"floorplan_png_base64\":\"...\"}\n\n## Configuration UI\n\nDashboard Settings panel -> \"Notifications\" tab:\n- Delivery channel selector: None / ntfy / Pushover / Webhook\n- Channel-specific credential fields (ntfy server URL + topic + token, Pushover API key, webhook URL)\n- Test notification button: sends a test notification to verify configuration\n- Event type enable/disable toggles: per event type, can disable e.g. \"zone_enter\" while keeping \"fall_detected\" enabled\n- Quiet hours: time picker from/to, day-of-week selector\n- Smart batching toggle (default on)\n- \"Morning digest\" toggle (default on — delivers batched quiet-hours events at wake time)\n\n## Files to Create or Modify\n\n- mothership/internal/render/floorplan.go: floor-plan PNG renderer\n- mothership/internal/notifications/manager.go: NotificationManager, batching, quiet hours logic\n- mothership/internal/notifications/ntfy.go: ntfy delivery client\n- mothership/internal/notifications/pushover.go: Pushover delivery client\n- mothership/internal/notifications/webhook.go: generic webhook delivery\n- mothership/internal/dashboard/routes.go: GET/PUT /api/settings/notifications, POST /api/notifications/test\n\n## Tests\n\n- Test floor-plan renderer produces a 300x300 PNG with correct dimensions\n- Test that zone boundaries appear in the rendered PNG at correct coordinates (check pixel colors at known positions)\n- Test batching: 3 LOW events within 10s -> 1 notification; 1 URGENT event -> immediate even if batching timer is active\n- Test quiet hours gate: LOW event at 23:00 with quiet hours 22:00-07:00 -> queued; URGENT event at 23:00 -> delivered immediately\n- Test morning digest delivery: queued events are bundled and delivered at quiet_hours_end\n- Test ntfy delivery with mock HTTP server: verify correct headers and body format\n- Test webhook delivery with mock HTTP server: verify correct JSON body and base64 PNG field\n- Test test-notification endpoint fires correctly\n\n## Acceptance Criteria\n\n- Notification received via ntfy within 5 seconds of trigger event for URGENT priority\n- Floor-plan PNG correctly shows zone boundaries and person positions in the notification\n- Smart batching prevents more than one notification per 30-second window for LOW events\n- Quiet hours suppress LOW/MEDIUM notifications and queue them for morning digest\n- Fall detection and anomaly alerts always bypass quiet hours\n- Morning digest delivered correctly at quiet hours end\n- Test notification button correctly verifies channel configuration\n- Tests pass","status":"open","priority":3,"issue_type":"task","created_at":"2026-03-28T01:48:19.528717849Z","created_by":"coding","updated_at":"2026-03-28T03:29:14.371730406Z","source_repo":".","compaction_level":0,"original_size":0,"dependencies":[{"issue_id":"spaxel-zpt","depends_on_id":"spaxel-c0q","type":"blocks","created_at":"2026-03-28T03:29:14.371640840Z","created_by":"coding","metadata":"{}","thread_id":""},{"issue_id":"spaxel-zpt","depends_on_id":"spaxel-c1c","type":"blocks","created_at":"2026-03-28T01:48:23.948107860Z","created_by":"coding","metadata":"{}","thread_id":""},{"issue_id":"spaxel-zpt","depends_on_id":"spaxel-qlh","type":"blocks","created_at":"2026-03-28T01:48:23.975916991Z","created_by":"coding","metadata":"{}","thread_id":""}]} {"id":"spaxel-zvb","title":"Mothership: adaptive load shedding & resource throttling","description":"## Overview\nImplement a 4-level load shedding system to keep the fusion pipeline responsive under CPU/memory pressure, especially for large fleets.\n\n## Pipeline instrumentation\n- Time each of the 8 fusion pipeline stages per iteration using time.Since()\n- Maintain 5-iteration rolling average of total iteration time (ring buffer of 5 durations)\n\n## Load shedding state machine\nLevel 0 (normal): rolling avg < 80 ms — full pipeline\nLevel 1 (light): rolling avg >= 80 ms — suspend crowd flow accumulation (~3 ms saved/iter)\nLevel 2 (moderate): rolling avg >= 90 ms — also suspend CSI replay buffer writes (~2 ms saved/iter)\nLevel 3 (heavy): rolling avg >= 95 ms — drop CSI frames when ingest channel > 50% full;

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.

Fixed 'state.ws.close is not a function' errors during calibrate step cleanup.\n\n2. 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.
