grgsm_scanner fully buffers stdout when piped, so scan results never
reach Python until the buffer fills or process exits. Wrapping with
stdbuf -oL forces line-buffered output for real-time data streaming.
Also increased scan timeout from 120s to 300s since scanning 4 bands
legitimately takes 2-3 minutes.

The ptrkrysik/gr-gsm repo uses SWIG which is incompatible with
GNU Radio 3.10+. The bkerler fork supports modern GNU Radio and
builds successfully on current Ubuntu/Debian systems.
Updated all references in Dockerfile, setup.sh, dependencies.py,
and error messages.

apt-packaged gr-gsm aborts with SIGABRT (-6) due to duplicate FSM
registration in libosmocore. Setting this env var suppresses the
fatal assertion, allowing grgsm_scanner to run normally.
Applied to both scanner and livemon subprocess spawns.

grgsm_scanner exits in <300ms with osmo_fsm assertion error due to
libosmocore incompatibility. Added crash detection: if process exits
in <5s with non-zero code, counts as crash. After 3 crashes, stops
retrying and sends error to SSE stream so the UI can display it.
Also drains remaining queue items after process exits and logs exit
code and scan duration for diagnostics.

Global LOG_LEVEL defaults to WARNING, silencing all INFO/DEBUG logs.
GSM Spy needs verbose logging for scanner diagnostics. Override the
module logger level to DEBUG so scanner output is always visible.

gsm_spy.py used logging.getLogger() directly which returns a bare
logger with no handler. The parent 'intercept' logger has
propagate=False, so all GSM Spy logs were silently dropped.
Now uses utils.logging.get_logger() which adds a stderr handler
and sets the log level, matching all other route modules.

grgsm_scanner (like many GNU Radio tools) writes scan results to
stderr, not stdout. The stderr reader was only logging at debug
level and discarding lines. Now feeds stderr into the parse queue.
Also added info-level logging for all scanner output lines to aid
debugging.

Parser expected pipe-delimited table rows but grgsm_scanner outputs
comma-separated key-value pairs like:
ARFCN: 975, Freq: 925.2M, CID: 13522, LAC: 38722, MCC: 262, MNC: 1, Pwr: -58
This was the root cause of no data appearing in GSM Spy.

stop_scanner() cleared gsm_spy_active_device without calling
release_sdr_device(), so the device stayed claimed in the registry.
The scanner thread's finally block then saw None and skipped release.

UI was sending GSM900 but backend REGIONAL_BANDS expects EGSM900
for Europe and Asia regions, causing validation rejection.

GSM Spy was failing with FileNotFoundError because grgsm_scanner
wasn't installed. These tools are now installed automatically by
setup.sh (both Debian and macOS) and included in the Dockerfile,
matching how other tools like multimon-ng and ffmpeg are handled.
- setup.sh: Remove ask_yes_no prompts for gr-gsm and tshark, install
unconditionally; add check_recommended tier for final summary
- Dockerfile: Add tshark to apt layer, add gr-gsm RUN layer with
apt-then-source-build fallback, preseed debconf for tshark
- gsm_spy.py: Add shutil.which pre-check in start_scanner route,
catch FileNotFoundError in scanner_thread to stop retry loop

- kill_all() now resets gsm_spy_scanner_running and related state so
the scanner thread stops after killall
- scanner_thread sets flag to False instead of None on exit
- Restore alert_rules, alert_events, recording_sessions tables and
wifi_clients column removed by PR in database.py
- Escape all server-sourced values in analysis modals with escapeHtml()
- Reset gsm_towers_found/gsm_devices_tracked on stop to prevent
counter drift across sessions
- Replace raw terminate/kill with safe_terminate() in scanner_thread

The function-strip CSS was never linked in index.html, causing all
strip items to render as unstyled stacked elements instead of a
horizontal flex bar.

Move waterfall controls from the sidebar into a function-strip bar inside
#listeningPostVisuals so they sit directly above the waterfall canvas.
Also fix the "SDR device in use" error when clicking a waterfall frequency
to listen — the WebSocket waterfall's device claim wasn't being released
before the audio start request because the backend cleanup hadn't finished.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Zooming caused "I/Q capture process exited immediately" because the client
closed the WebSocket and opened a new one, racing with the old rtl_sdr
process releasing the USB device. Now zoom/retune sends a start command on
the existing WebSocket, and the server adds a USB release delay plus retry
loop when restarting capture within the same connection.

The FFT pipeline produces power values in the ~0-60 dB range for
normalized IQ data, but quantize_to_uint8 used a hardcoded range
of -90 to -20 dB. Every bin saturated to 255, producing a uniform
yellow waterfall with no signal differentiation.
Now auto-scales to the actual min/max of each frame so the full
colour palette is always used.

After a WebSocket handler exits, flask-sock returns a Response to
Werkzeug which writes "HTTP/1.1 200 OK..." on the still-open socket.
Browsers see these HTTP bytes as a malformed WebSocket frame, causing
"Invalid frame header".
Now the handler explicitly closes the raw TCP socket after the
WebSocket close handshake, so Werkzeug's write harmlessly fails.
Applied to both waterfall and audio WebSocket handlers.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
simple-websocket 1.1.0's receive(timeout=N) returns None on timeout
instead of raising TimeoutError. The handler treated None as
"connection closed" and broke out of the loop, causing Werkzeug to
write its HTTP 200 response on the still-open WebSocket socket.
The browser saw those HTTP bytes as an invalid WebSocket frame.
Now checks ws.connected to distinguish timeout (None + connected)
from actual close (None + not connected).

agents.js syncLocalModeStates() expects these endpoints to check
whether each mode is running locally. Both were missing, causing
404 errors on mode switch.

The before_request require_login hook was returning a 302 redirect
for WebSocket upgrade requests, which browsers report as "Invalid
frame header". WebSocket requests don't always carry session cookies
reliably. Allow /ws/ paths through the login check since the page
that initiates these connections already requires authentication.
Also keeps the prior fix: serialize WebSocket sends through a queue
to avoid concurrent read/write on the non-thread-safe simple-websocket.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The fft_reader thread was calling ws.send() concurrently with
ws.receive() in the main loop. simple-websocket is not thread-safe
for simultaneous read/write, corrupting frame headers. Now the reader
thread enqueues frames and only the main loop touches the WebSocket.

Replace the batch rtl_power SSE pipeline with continuous I/Q streaming
via WebSocket for smooth ~25fps waterfall display. The server captures
raw I/Q samples (rtl_sdr/rx_sdr), computes Hann-windowed FFT, and
sends compact binary frames (1035 bytes vs ~15KB JSON, 93% reduction).
Client falls back to existing SSE path if WebSocket is unavailable.

Waterfall clicks now auto-select the correct modulation for the frequency
band (e.g., WFM for FM broadcast, AM for airband) instead of using whatever
modulation was last selected. Adds a hover tooltip showing frequency and
suggested modulation. Fixes the kill-all notification to show a clean
"All processes stopped" message instead of listing "bluetooth_scanner".

Adds a phosphor-persistence waveform scope showing audio RMS/peak
levels during ISS SSTV and General SSTV decoding, matching the
existing pager scope pattern with a purple color scheme.

Enable -M level on rtl_433 to include RSSI/SNR in decoded JSON, extract
signal levels and push scope events to the SSE stream. Renders a green-

Tap the rtl_fm → multimon-ng audio pipeline via a relay thread to extract

Reverts IQ pipeline and removes syncWaterfallToFrequency calls from
pager, sensor, rtlamr, DMR, SSTV, and SSTV general modes. Waterfall
is now exclusive to listening post mode.

Replace rtl_fm/rtl_433 with rtl_sdr for raw IQ capture when available,
enabling a Python IQ processor to compute FFT for the waterfall while
simultaneously feeding decoded data to multimon-ng (pager) or rtl_433
(sensor). Falls back to the legacy pipeline when rtl_sdr is unavailable.

1. utils/weather_sat.py — Added delete_all_images() method that globs for *.png, *.jpg, *.jpeg in the output dir, unlinks each, clears _images list, and returns the
count.
2. routes/weather_sat.py — Added DELETE /weather-sat/images route that calls decoder.delete_all_images() and returns {'status': 'ok', 'deleted': count}.
3. static/js/modes/weather-satellite.js:
- Added currentModalFilename state variable
- renderGallery() now sorts images by timestamp descending, groups by date using toLocaleDateString(), renders date headers spanning the grid, and adds a delete
overlay button on each card
- showImage() accepts a filename param, stores it in currentModalFilename, and creates a modal toolbar with a delete button
- Added deleteImage(filename) — confirm dialog → DELETE /weather-sat/images/{filename} → filter from array → re-render + close modal
- Added deleteAllImages() — confirm dialog → DELETE /weather-sat/images → clear array → re-render
- Exposed deleteImage, deleteAllImages, and _getModalFilename in public API
4. static/css/modes/weather-satellite.css:
- Added position: relative to .wxsat-image-card
- .wxsat-image-actions — absolute top-right overlay, hidden by default, appears on card hover
- .wxsat-image-actions button — dark background, turns red on hover
- .wxsat-date-header — full-grid-width date separator with dimmed uppercase text
- .wxsat-modal-toolbar — absolute top-left in modal for the delete button
- .wxsat-modal-btn.delete — turns red on hover
- .wxsat-gallery-clear-btn — subtle icon button, pushed right via margin-left: auto, turns red on hover
- Updated .wxsat-gallery-header from justify-content: space-between to gap: 8px for proper 3-child layout
5. templates/index.html — Added clear-all trash button with SVG icon in the gallery header, wired to WeatherSat.deleteAllImages().
The reader thread loop checks self._running but it was being set to
True after _start_satdump() returned, which is after the thread
already started. The thread would see _running=False and exit
immediately without reading any SatDump output.

SatDump writes to stderr via fwrite() with its custom logger. When
stderr is redirected to a pipe, C runtime fully buffers it. Neither
stdbuf nor bufsize settings help since SatDump doesn't use stdio for
output.
PTY (pseudo-terminal) makes SatDump think it's writing to a real
terminal, which disables buffering. Also strips ANSI escape codes
from the output and properly handles \r progress lines.

Merges upstream changes into fork while preserving weather satellite
(NOAA APT/Meteor LRPT via SatDump), rtlamr, multi-arch build, and
decoder console features from our branch.
