The sweep loop's WiFi/BT/RF scan processing had unprotected
timeline_manager.add_observation() calls that could crash an entire
scan iteration, silently preventing all device events from reaching
the frontend. Additionally, scan interval timestamps were only updated
at the end of processing, causing tight retry loops on persistent errors.
- Wrap timeline observation calls in try/except for all three protocols
- Move last_*_scan timestamp updates immediately after scan completes
- Add per-device try/except so one bad device doesn't block others
- Emit sweep_progress after WiFi scan for real-time status visibility
- Log warning when WiFi scan returns 0 networks for easier diagnosis
- Add known_device and score_modifier fields to correlation engine
- Add TSCM scheduling, cases, known devices, and advanced WiFi indicators

- Add fallback direct DOM manipulation in agents.js selectAgent()
- Fix setListeningPostRunning to check agent mode before re-enabling button
- Add debug logging for button state changes
Agent scanner fixes:
- Use non-blocking I/O with select/fcntl to prevent blocking reads
- Pass dwell_time parameter through to scanner function
- Add freqs_scanned counter to status and data endpoints
- Improve SDR test process cleanup with kill() fallback
Frontend listening post fixes:
- Add setListeningPostRunning for UI sync when switching to agent
- Fix button ID (radioScanBtn not scannerStartBtn)
- Handle nested data structure from controller proxy
- Update freqs_scanned and signal_count from polling data
- Disable listen button for agent mode (audio can't stream over HTTP)
Add listening_post to agents.js uiSetters map for mode sync.
Live testing completed:
- Sensor mode: works via agent
- WiFi quick scan: works via agent
- Listening post: works via agent (AM airband, WFM broadcast tested)
- Signal detection: confirmed working via agent
Testing ongoing - modes not yet tested via agent:
- Pager, ADS-B, AIS, ACARS, APRS, DSC, RTL-AMR, TSCM, Bluetooth
- Agent: Add _detect_acarsdec_fork() for f00b4r0/DragonOS support
- Agent: Use --output json:file, --rtlsdr, -m 256 for f00b4r0 fork
- UI: Add setAcarsRunning() to sync button state with agent
- UI: Add 'acars' to syncModeUI uiSetters map
Agent fixes:
- Fix stop not killing secondary processes (pager_rtl, aprs_rtl, rtlamr_tcp)
- Modes using piped processes now properly terminate all child processes
UI state sync fixes:
- Add syncLocalModeStates() to check local status when switching to local
- Fix switchMode() to re-sync with agent/local when changing mode tabs
- Only stop local modes when actually in local mode
- UI now correctly reflects running state when switching agents or modes
- Fix device dropdown for agent mode by checking sdr_devices key
- Fix pager checkStatus() to use agent endpoint when in agent mode
- Fix WiFi checkScanStatus() to be agent-aware
- Fix Bluetooth checkScanStatus() to be agent-aware
These fixes prevent the UI from reverting to 'stopped' state when
the agent is actually running a mode.
- Agent TSCM uses same ThreatDetector and CorrelationEngine as local mode
- Added baseline_id parameter support using get_tscm_baseline()
- Fixed RF scan stop_check to allow agent-specific stop events
- Fixed 'undefined MHz' display for WiFi devices (added essid fallback and null check)
- Fixed signal strength type conversion (string to int) for correlation engine
- Agent threat detection matches local mode behavior:
- No baseline: detects anomaly/hidden_camera threats only
- With baseline: also detects new_device threats
Health Monitoring:
- Add /controller/agents/health endpoint for efficient bulk health checks
- Check all agents in one call with response time tracking
- Update agent status in real-time (30s interval)
- Show latency next to agent status in UI
- Add collapsible "All Agents Health" panel in sidebar
- Log console notifications when agents go online/offline
Response Utilities:
- Add unwrapAgentResponse() to consistently handle controller proxy format
- Add isAgentMode() and getCurrentAgentName() helpers
- Standardize error handling for agent responses
UI Improvements:
- Show response latency (ms) in agent selector dropdown
- Health panel shows status + running modes for each agent
- Better visual feedback for agent status changes
Agent improvements:
- Add process verification (0.5s delay + poll check) for sensor, pager, APRS, DSC modes
- Prevents silent failures when SDR is busy or tools fail to start
- Returns clear error messages when subprocess exits immediately
Frontend agent integration:
- Add agent routing to all SDR modes (pager, sensor, RTLAMR, APRS, listening post, TSCM)
- Add agent routing to WiFi and Bluetooth modes with polling fallback
- Add agent routing to AIS and DSC dashboards
- Implement "Show All Agents" toggle for Bluetooth mode
- Add agent badges to device/network lists
- Handle controller proxy response format (nested 'result' field)
Controller enhancements:
- Add running_modes_detail endpoint showing device info per mode
- Support SDR conflict detection across modes
Documentation:
- Expand DISTRIBUTED_AGENTS.md with complete API reference
- Add troubleshooting guide and security considerations
- Document all supported modes with tools and data formats
UI/CSS:
- Add agent badge styling for remote vs local sources
- Add WiFi and Bluetooth table agent columns
Features:
- Standalone agent server (intercept_agent.py) for remote sensor nodes
- Controller API blueprint for agent management and data aggregation
- Push mechanism for agents to send data to controller
