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

When monitor mode is toggled on a remote agent, the controller now
automatically refreshes the agent's capabilities and updates the
database. This keeps the UI interface list in sync without requiring
a manual refresh.
Agent fixes:
- Fix Ctrl+C hang by running cleanup in background thread
- Add force-exit on double Ctrl+C
- Improve exception handling in output reader threads to prevent
bad file descriptor errors on shutdown
- Reduce cleanup timeouts for faster shutdown
Controller/UI fixes:
- Add URL validation for agent registration (check port, protocol)
- Show helpful message when agent is unreachable during registration
- Clarify API key field label (reserved for future use)
- Add client-side URL validation with user-friendly error messages
WiFi agent mode fixes:
- Add polling fallback for deep scan when push mode is disabled
- Polls /controller/agents/{id}/wifi/data every 2 seconds
- Detect running scans when switching to an agent
- Fix scan_mode detection (agent uses params.scan_type)
- 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
- Pull mechanism for controller to proxy requests to agents
- Multi-agent SSE stream for combined data view
- Agent management page at /controller/manage
- Agent selector dropdown in main UI
- GPS integration for location tagging
- API key authentication for secure agent communication
- Integration with Intercept's dependency checking system
