When rtl_fm exits unexpectedly, read its stderr output to diagnose
the failure (no device, permission denied, etc.) and include the
error message in both the server log and the SSE progress event
sent to the browser.

Three bugs preventing the live SSTV pipeline from working:
1. Race condition: self._running was set AFTER starting the decode
thread, so the thread checked the flag, found it False, and exited
immediately without ever processing audio.
2. Ghost running state: when the decode thread exited (e.g. rtl_fm
died), self._running stayed True. The decoder reported as running
but was dead, and subsequent start() calls returned without doing
anything - permanently stuck until app restart.
3. VIS detection fragility: unclassifiable windows at tone transition
boundaries (mixed energy from two tones) caused the state machine
to reset from LEADER/BREAK states back to IDLE, dropping valid
VIS headers on real signals.

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.

Uncomment and enable the ./data:/app/data volume mount on both the
basic and history service profiles. This persists decoded weather
satellite images, the SQLite database, and other data across
container rebuilds. Critical for Docker-only deployments.

Add defensive typeof checks before referencing the Updater global in
loadUpdateStatus() and checkForUpdatesManual() so the settings panel
shows a helpful message instead of crashing. Also swap script load
order so updater.js loads before settings-manager.js.

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.
