Werkzeug's dev server buffers SSE response headers until the first body byte
is written. With keepalive_interval=30s, opening two SSE connections on
DOMContentLoaded (satellite stream + new ground station stream) meant the
browser waited 30 seconds before receiving any response bytes from either
connection. Browsers keep their loading indicator active while connections are
pending, causing the satellite dashboard to appear stuck loading.
Fix: yield an immediate keepalive at the start of sse_stream_fanout so every
SSE endpoint flushes headers + first data to the browser instantly.

- Add --no-cache-dir and --timeout 120 to all pip calls to prevent hanging
on corrupt/stale pip HTTP cache (cachecontrol .pyc issue)
- Replace silent python -c import verification with pip show to avoid
import-time side effects hanging the installer
- Switch optional packages to --only-binary :all: to skip source compilation
on Python versions without pre-built wheels (prevents gevent/numpy hangs)
- Warn early when Python 3.13+ is detected that some packages may be skipped
- Add ground track caching with 30-minute TTL to satellite route
- Add live satellite position tracker background thread via SSE fanout
- Add satellite_predict, satellite_telemetry, and satnogs utilities

When dump1090 lacks native --enable-biast support, the system now falls
back to rtl_biast (RTL-SDR Blog drivers) to enable bias-t power before
starting dump1090. The Blog V4's built-in LNA requires bias-t to
receive ADS-B signals.

get_setting() now catches sqlite3.OperationalError and returns the
default value. Previously, an inaccessible database (e.g. root-owned
instance/ from sudo) caused inject_offline_settings to crash every
page render with 500 Internal Server Error.

The default ADMIN_PASSWORD was an empty string, triggering random
password generation on first run — contradicting the README which
states admin:admin. Additionally, editing config.py after first run
had no effect since init_db() only seeded users on an empty table.
- Change default ADMIN_PASSWORD from '' to 'admin'
- Sync admin credentials from config on every startup so that
changes to config.py or env vars take effect without wiping the DB

ensureModeScript() used document.body.appendChild() to load lazy mode
scripts, but the preload for ?mode= query params runs in <head> before
<body> exists, causing all deep-linked modes to silently fail.
Also fix cross-mode handoffs (BT→BT Locate, WiFi→WiFi Locate,
Spy Stations→Waterfall) that assumed target module was already loaded.

Critical:
- Pass sdr_type_str to claim/release_sdr_device (was missing 3rd arg)
- Add ook_active_sdr_type module-level var for proper device registry tracking
- Add server-side range validation on all timing params via validate_positive_int
Major:
- Extract cleanup_ook() function for full teardown (stop_event, pipes, process,
SDR release) — called from both stop_ook() and kill_all()
- Replace Popen monkey-patching with module-level _ook_stop_event/_ook_parser_thread
- Fix XSS: define local _esc() fallback in ook.js, never use raw innerHTML
- Remove dead inversion code path in utils/ook.py (bytes.fromhex on same
string that already failed decode — could never produce a result)
Minor:
- Status event key 'status' → 'text' for consistency with other modules
- Parser thread logging: debug → warning for missing code field and errors
- Parser thread emits status:stopped on exit (normal EOF or crash)
- Add cache-busting ?v={{ version }}&r=ook1 to ook.js script include
- Fix gain/ppm comparison: != '0' (string) → != 0 (number)
Tests: 22 → 33 (added start success, stop with process, SSE stream,
timing range validation, stopped-on-exit event)

- Add HackRF/SoapySDR-specific error messages in ADS-B startup
- Add HackRF waterfall support via rx_sdr IQ capture + FFT

- Fix XSS: escape ASCII output in innerHTML via escapeHtml()
- Fix deadlock: use put_nowait() for queue ops under ook_lock
- Fix SSE leak: add ook to moduleDestroyMap so switching modes
closes the EventSource
- Fix RSSI: explicit null check preserves valid zero values in
JSON export
- Add frame cap: trim oldest frames at 5000 to prevent unbounded
memory growth on busy bands
- Validate timing params: wrap int() casts in try/except, return
400 instead of 500 on invalid input
- Fix PWM hint: correct to short=0/long=1 matching rtl_433
OOK_PWM convention (UI, JS hints, and cheat sheet)
- Fix inversion docstring: clarify fallback only applies when
primary hex parse fails, not for valid decoded frames

- Fix double-scroll by switching ookOutputPanel to flex layout
- Keep decoded frames visible after stopping (persist for review)
- Wire global Clear/CSV/JSON status bar buttons to OOK functions

- Timing presets: five quick-fill buttons (300/600, 300/900, 400/800, 500/1500, 500 MC)
that populate all six pulse-timing fields at once — maps to CTF flag timing profiles
- RSSI per frame: add -M level to rtl_433 command; parse snr/rssi/level from JSON;
display dB SNR inline with each frame; include rssi_db column in CSV export
- Auto bit-order suggest: "Suggest" button counts printable chars across all stored
frames for MSB vs LSB, selects the winner, shows count — no decoder restart needed
- Pattern filter: live hex/ASCII filter input above the frame log; hides non-matching
frames and highlights matches in green; respects current bit order
- TSCM integration: "Decode (OOK)" button in RF signal device details panel switches
to OOK mode and pre-fills frequency — frontend-only, no backend changes needed

Several modes didn't pass sdr_type to claim_sdr_device(), defaulting to
'rtlsdr' and triggering an rtl_test USB probe that fails for HackRF with
a confusing "check that the RTL-SDR is connected" message.
- Add sdr_type to frontend start requests for rtlamr, weather-sat, sstv-general
- Read sdr_type in backend routes and pass to claim/release_sdr_device()
- Add early guard returning clear "not yet supported" error for non-RTL-SDR
hardware in modes that are hardcoded to RTL-SDR tools
- Make probe_rtlsdr_device error message device-type-agnostic

When the /devices fetch hasn't completed or fails, parseInt on an empty
select returns NaN which JSON-serializes to null. The backend then calls
int(None) and raises TypeError. Fix both layers: frontend falls back to
0 on NaN, backend uses `or` defaults so null values don't bypass the
fallback.
Also adds a short TTL cache to detect_all_devices() so multiple
concurrent callers on the same page load don't each spawn blocking
subprocess probes.

Stock rtl-sdr packages don't support the -T bias-tee flag (only
RTL-SDR Blog builds do). Passing -T to stock rtl_sdr causes an
immediate exit, breaking meteor scatter and waterfall modes.
Now probes the tool's --help output before adding -T, with a regex
that avoids false-matching "DVB-T" in the description text.

Full-stack meteor scatter monitoring mode that captures IQ data from
an RTL-SDR, computes FFT waterfall frames via WebSocket, and runs a
real-time detection engine to identify transient VHF reflections from
meteor ionization trails (e.g. GRAVES radar at 143.050 MHz).
Backend: MeteorDetector with EMA noise floor, SNR threshold state
machine (IDLE/DETECTING/ACTIVE/COOLDOWN), hysteresis, and CSV/JSON
export. WebSocket at /ws/meteor for binary waterfall frames, SSE at
/meteor/stream for detection events and stats.
Frontend: spectrum + waterfall + timeline canvases, event table with
SNR/duration/confidence, stats strip, turbo colour LUT. Uses shared
SDR device selection panel with conflict tracking.

SSE EventSource connections for AIS, ACARS, VDL2, and radiosonde were
not closed when switching modes, causing fd exhaustion after repeated
switches. Also fixes socket leaks on exception paths in AIS/ADS-B
stream parsers, closes subprocess pipes in safe_terminate/cleanup, and
caches skyfield timescale at module level to avoid per-request fd churn.

sqlite3.connect() opens read-only files without error — the failure

Extends the rtl_tcp support (added in c1339b6 for APRS, Morse, DSC) to
the weather satellite mode. When a remote SDR host is provided, SatDump
uses --source rtltcp instead of --source rtlsdr, local device claiming
is skipped, and the frontend sends rtl_tcp params via getRemoteSDRConfig().

The custom SIGINT/SIGTERM handler in utils/process.py overrode
gunicorn's own signal management, causing KeyboardInterrupt to fire
inside the gevent worker on Ctrl+C instead of allowing gunicorn's
graceful shutdown. Now detects if another signal manager (gunicorn)
has already installed handlers and defers to it.

Re-implements envelope detection on top of the rewritten Morse decoder.
Addresses PR #160 review feedback:
- Rebase: rebuilt on current upstream/main (lifecycle state machine)
- Gap thresholds: 2.0/5.0 for envelope only; goertzel keeps 2.6/6.0
- Frequency validation: max_mhz=1766 for envelope, 30 for goertzel
- Tests: EnvelopeDetector unit tests + envelope-mode decoder test
- Envelope uses direct magnitude threshold (no SNR/noise ref)
- Goertzel path completely unchanged

rtl_test opens the USB device during probing. After killing the
process, the kernel may not release the USB interface immediately.
dump1090 then fails with usb_claim_interface error -6. Add a 0.5s
delay after probe cleanup to allow the kernel to fully release the
device before the actual decoder opens it.

rtl_test -t often exits non-zero after finding a device (e.g.
"No E4000 tuner found, aborting" with R820T tuners). The return
code fallback was firing even when the "Found N device(s)" success
message had already been matched. Track device_found separately
and only use return code as fallback when no success was seen.

Move adsb_active_device/sdr_type assignment to immediately after
claim_sdr_device so stop_adsb() can always release the device, even

claim/release key mismatch. Clear active device on all error paths.
Replace blind 3s sleep for dump1090 readiness with port-polling loop
(100ms intervals, 3s max). Replace subprocess.run() in rtl_test probe
