slowrx is a GTK GUI app that doesn't support CLI usage, so the SSTV
decoder was silently failing. This replaces it with a pure Python
implementation using numpy and Pillow that supports Robot36/72,
Martin1/2, Scottie1/2, and PD120/180 modes via VIS header auto-detection.
Key implementation details:
- Generalized Goertzel (DTFT) for exact-frequency tone detection
- Vectorized batch Goertzel for real-time pixel decoding performance
- Overlapping analysis windows for short-window frequency estimation
- VIS header detection state machine with parity validation
- Per-line sync re-synchronization for drift tolerance

rtl_fm stderr was sent to DEVNULL, hiding the actual failure reason
(rc=1). Now captured and surfaced in the error response. Also drains
rtl_fm stderr during normal operation to prevent pipe blocking.

Use -o - (stdout) instead of -o /dev/null for audio output, as
dsd-fme expects specific output targets. Remove -N flag which may
cause issues in headless mode. Add stderr capture on pipeline
failure for better error messages.

dsd-fme uses different protocol flags than classic dsd (e.g. -fs for
DMR instead of -fd, -f1 for P25 instead of -fp). Add -N flag to
disable ncurses terminal which is required when reading from stdin pipe.

Check for dsd-fme binary (common fork) before falling back to dsd.
Disable audio output with -o /dev/null to prevent PulseAudio
connection failures when running under sudo.

Adds a general-purpose SSTV decoder alongside the existing ISS SSTV mode,
supporting USB/LSB/FM modulation on common amateur radio HF/VHF/UHF
frequencies (14.230 MHz USB, 3.845 MHz LSB, etc.) with auto-detection
of modulation from preset frequency table.

Add SDR device reservation to prevent conflicts with other modes, and
capture rtl_fm stderr so actual error messages are reported to the user
instead of a generic exit code.

Replace fragile platform-specific WiFi detection with the same
scanner._detect_interfaces() used by the actual scanning code,
eliminating false "No wireless interfaces found" warnings.

- Use networksetup instead of deprecated airport utility for macOS WiFi detection
- Fix SDRDevice attribute access (use getattr instead of dict .get())
- Move Detected Threats panel next to RF Signals in 2-column grid
- Always run correlation/identity analysis at sweep end, even if stopped by user

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

Open Notify API (api.open-notify.org) is frequently unreliable,
causing 5-second timeout delays on every ISS position request.
Promote wheretheiss.at as the primary API in both satellite.py
and sstv.py, demoting Open Notify to fallback.

The /wifi/v2/clients endpoint was returning all clients regardless
of query parameters, because a duplicate route in wifi.py took
precedence over the filtered one in wifi_v2.py. Added bssid,
associated, and min_rssi filtering to the active route.

Add retry mechanism (3 attempts) for usb_claim_interface errors when
the SDR device hasn't been fully released by a previous process. Also
kill rtl_power alongside rtl_fm during cleanup and increase the USB
release delay.

Adds POST /updater/restart endpoint that gracefully restarts the
application using os.execv. Cleans up all decoder processes and
global state before replacing the process with a fresh instance.

Implements centralized tracking of SDR device allocation to prevent
multiple decoders from trying to use the same device simultaneously.
- Add sdr_device_registry with claim/release/status functions in app.py
- Update all SDR-based routes to claim devices on start and release on stop
- Return HTTP 409 with DEVICE_BUSY error when device is already in use
- Clear registry on /killall
- Skip device claims for remote connections (rtl_tcp, remote SBS)

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)
Allow connecting to WiFi-enabled Meshtastic devices via TCP/IP in
addition to USB/Serial connections. This enables remote monitoring
of mesh nodes that have WiFi capability (T-Beam, Heltec WiFi LoRa, etc).
- Add connection_type parameter ('serial' or 'tcp') to /meshtastic/start
- Add hostname parameter for TCP connections
- Update UI with connection type dropdown and hostname input field
- Show connection type in status responses

- New /sstv/doppler endpoint for real-time Doppler info
- Start endpoint accepts latitude/longitude for automatic tracking
Also:

- Add refresh_tle_data() function for reusable TLE updates
- Automatically fetch fresh TLE from CelesTrak when app starts
- Runs in background thread to avoid slowing down startup
- Includes NOAA-20 and NOAA-21 in name mappings
- Gracefully handles failures (uses cached data if offline)
- Existing /update-tle endpoint now uses shared function
This ensures satellite tracking data is always fresh, fixing
inaccurate positions caused by stale TLE data.
