- 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.

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.

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".

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.

Stream threads for sensor, pager, acars, rtlamr, dmr, and dsc modes
never called release_sdr_device() when their SDR process crashed,
leaving devices permanently locked in the registry. Also fixes orphaned
companion processes (rtl_fm, rtl_tcp) not being killed on crash, start
path failures leaking processes, DMR stop handler missing lock, and
listening post/audio websocket pkill nuking all system-wide rtl_fm
processes. Wires up register_process()/unregister_process() so the
atexit/signal cleanup safety net actually works, and adds rtl_tcp,
rtl_power, rtlamr, ffmpeg to the killall endpoint.

Fix infinite CPU spin in PD120 decoding caused by a 1-sample rounding
mismatch between line_samples (24407) and the sum of sub-component
samples (24408). The feed() while loop would re-enter _decode_line()
endlessly when the buffer was too short by 1 sample. Added a stall
guard that breaks the loop when no progress is made.
Fix false "leader tone detected" in the signal monitor by requiring
the detected tone to dominate the other tone by 2x, matching the
approach already used by the VIS detector.

When the WiFi interface is down (e.g. USB adapter not activated),
scanning fails with "Network is down" errors. Now the scanner
proactively checks interface state via /sys/class/net and brings
it up using ip link (or ifconfig fallback) before attempting scans,
with a retry loop if the initial scan still fails.

The Receiver Count section had no <h3> so it didn't get collapsible
