CMake 4.0 removed backward compat with cmake_minimum_required < 3.5.
Add -DCMAKE_POLICY_VERSION_MINIMUM=3.5 to acarsdec cmake invocations
in setup.sh (macOS + Debian) and Dockerfile.

start_gpsd_daemon() acquires _gpsd_process_lock then calls
stop_gpsd_daemon() which tries to acquire the same non-reentrant Lock,
causing an immediate deadlock. Changed to RLock so the same thread can
re-enter the lock.

Bluetooth enhancements (service data inspector, appearance codes, MAC
cluster tracking, behavioral flags, IRK badges, distance estimation),
ACARS SoapySDR multi-backend support, dump1090 stale process cleanup,
GPS error state, and proximity radar/signal card UI improvements.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
New modes:
- BT Locate: SAR Bluetooth device location with GPS-tagged signal trail,
RSSI-based proximity bands, audio alerts, and IRK auto-extraction from
paired devices (macOS plist / Linux BlueZ)
- GPS: Real-time position tracking with live map, speed, heading, altitude,
satellite info, and track recording via gpsd
Bug fixes:
- Fix ABBA deadlock between session lock and aggregator lock in BT Locate
- Fix bleak scan lifecycle tracking in BluetoothScanner (is_scanning property
now cross-checks backend state)
- Fix map tile persistence when switching modes
- Use 15s max_age window for fresh detections in BT Locate poll loop
Documentation:
- Update README, FEATURES.md, USAGE.md, and GitHub Pages with new modes

SatDump is a large C++ project that can take 10-30 minutes to compile.
Previously all build output was sent to /dev/null, making it appear
hung. Now shows a progress message every 30 seconds, sets time
expectations upfront, and displays the build log on failure.

The upstream acarsdec uses pthread_tryjoin_np (a Linux-only GNU
extension) and has broken libacars linking on macOS. The setup script
now patches both issues at build time, along with the existing compiler
flag fix for ARM64.

Strip ITU-R M.493 phasing symbols (120-126) after dot pattern sync before
decoding message content. Fix MMSI BCD digit trimming direction and correct
test symbol encodings for position and MMSI edge cases.
Satellites added via CelesTrak import or TLE paste are now stored in
SQLite and survive page reloads and app restarts. Adds CRUD API
endpoints and wires frontend sidebar + dashboard to use them.

Weather satellite decoding (NOAA APT & Meteor LRPT) was added in the
Dockerfile but setup.sh had no SatDump support, leaving local installs
with a broken weather satellite mode. Adds build-from-source functions
for both Debian and macOS, a check_optional entry, and prompted install
steps in both platform installers.

Starting ffmpeg at decoder launch caused a pipe-buffer deadlock: ffmpeg
stdout filled up (~64KB on Linux) before the browser connected to the
audio stream, back-pressuring the entire pipeline and freezing dsd-fme
stderr output (no text data, no syncs, no calls).
New architecture: a mux thread always drains dsd-fme stdout to keep the
pipeline flowing. ffmpeg starts lazily per-client when /dmr/audio/stream
is requested (matching the listening post pattern). The mux forwards
decoded audio to the active ffmpeg with silence fill during voice gaps,
and discards audio when no client is connected.

Digital voice is intermittent — dsd-fme only outputs PCM during active
voice transmissions. Without input, ffmpeg never wrote the WAV header
and the browser got an empty response. Add an audio bridge thread that
feeds 100ms silence chunks during voice gaps so ffmpeg always has input
and the browser receives a continuous WAV stream. Add auto-reconnect
on the frontend if the audio stream drops while the decoder is running.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Stream decoded digital voice audio to the browser via ffmpeg pipeline
(dsd-fme 8kHz PCM → ffmpeg → 44.1kHz WAV → chunked HTTP). Persist
frequency/protocol/gain/ppm settings in localStorage so they survive
page navigation. Add bookmark system for saving and recalling frequencies.

Wait for server-side WebSocket stop confirmation before closing the
connection, ensuring the IQ process is fully terminated and the USB
device released. Add retry logic with back-off in the audio start
endpoint as defense-in-depth for any remaining timing gaps.

The box-drawing character filter was dropping ANY line containing │ or ─,
including dsd-fme data lines that use these as column separators (e.g.
"DMR BS │ Slot 1 │ TG: 12345 │ SRC: 67890"). Now only filters lines
that are purely decorative (no alphanumeric content).
Also adds -J /dev/stderr so dsd-fme writes its event log to stderr
where we capture it, and debug logging of raw stderr lines.

-fd means D-STAR in dsd-fme, not DMR — causing sync detection
(shared C4FM modulation) but no decoded data. DMR Simplex is -fs.
Also fix -o - (invalid in dsd-fme) to -o null for headless servers,
add D-STAR flag mapping, and handle TGT/SRC output format in parser.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
dsd-fme remapped several flags from classic DSD: -fp is ProVoice (not
P25), -fi is NXDN48 (not D-Star), -fv doesn't exist. This caused P25
to trigger ProVoice decoding and D-Star to trigger NXDN48. Corrected
flag table and added C4FM modulation hints for better sync reliability.
Also fixes: device panel showing "DMR" regardless of protocol, signal
activity status flip-flopping between LISTENING and IDLE, and rtl_fm
squelch chopping the bitstream mid-frame. Adds PPM correction and
relax CRC controls for fine-tuning on marginal signals.

Security: replace path traversal-vulnerable str().startswith() with
is_relative_to(), anchor path checks to app root, strip filesystem
paths from error responses, add decoder-level path validation.
Architecture: use safe_terminate/register_process for subprocess
lifecycle, replace custom SSE generator with sse_stream(), use
centralized validate_* functions, remove unused app.py declarations.
Bugs: add thread-safe singleton locks, protect _images list across
threads, move blocking process.wait() to async daemon thread, fix
timezone handling for tz-aware datetimes, use full path for image
deduplication, guard TLE auto-refresh during tests, validate
scheduler parameters to avoid 500 errors.
Docker: pin SatDump to v1.2.2 and slowrx to ca6d7012, document
INTERCEPT_IMAGE fallback pattern.

When the backend has an active DMR session but the frontend lost track
(page refresh, broken flags causing silent running), clicking Start

When an external process (or stale handle from a crash) holds an SDR
device, claim_sdr_device() registry check passes but rtl_fm fails with
usb_claim_interface error -6. This adds a quick rtl_test probe inside

decoder pipeline is launched.

- Fix infinite loop in updateAprsStationList: querySelectorAll returns a
static NodeList so the while(cards.length > 50) loop never terminated,
crashing the page. Use live childElementCount instead.
- Fix station list pushing map off-screen by adding overflow:hidden and
min-height:0 to flex containers so only the station list scrolls.
- Cap backend aprs_stations dict at 500 entries with oldest-eviction to
prevent unbounded memory growth.

The monitored tower may have CID=0 (partially decoded cell) which
OpenCellID can't geocode, leaving it without coordinates. The heatmap
now falls back through: monitored tower by ARFCN, any geocoded tower,
then observer location. Also tracks the monitored ARFCN so the fallback
can find the right tower even when CID matching fails.

The heatmap silently failed when: CID types mismatched (string vs number),
LAC wasn't checked (wrong tower matched), or no data existed yet (button
showed ON with no layer). Now coerces CID/LAC to Number for comparison,
validates coordinates with parseFloat, logs match diagnostics to console,
and only shows ON when the layer is actually rendered.
