- 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.

Remove all GSM cellular intelligence features including tower scanning,
signal monitoring, rogue detection, crowd density analysis, and
OpenCellID integration across routes, templates, utils, tests, and
build configuration.

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.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
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.

Adds a toggleable heatmap layer that visualizes crowd density data from
the existing /gsm_spy/crowd_density endpoint as a gradient overlay on the
map, with auto-refresh every 30s during active monitoring.

Add explicit band name mapping from internal names to grgsm_scanner's
accepted -b values (GSM900, GSM850, DCS1800, PCS1900). Bands without
a valid grgsm_scanner equivalent (GSM800, EGSM900_EXT) are skipped
with a log message instead of crashing the scanner. Remove GSM800
from the dashboard band selector since it can't be scanned.

Parse tshark GSM field values with int(value, 0) instead of int(value)
to auto-detect hex 0x-prefixed output (e.g. 0x039e for TMSI/LAC/CID).
Without this, every tshark line with hex values fails to parse, causing
0 devices to be captured during monitoring.
Also add API Keys tab to Settings modal for configuring OpenCellID key
via the UI (in addition to env var), with status display and usage bar.

Wire SIGNALS/DEVICES/CROWD counters to monitor_heartbeat SSE data so
they update in real-time during monitoring. Redesign device list items
as richer cards with type badges, TA/distance, and observation counts.
Add clickable device detail modal with full device info and copy
support. Improve tower list with signal strength bars. Widen right
sidebar and bump list font sizes for readability.

Backend: monitor_thread sends periodic monitor_heartbeat events (every
5s) with elapsed time, packet count, and device count so the frontend
knows monitoring is active.
Frontend: new monitoring overlay replaces scan progress bar when
auto-monitor starts. Shows pulsing green indicator, ARFCN being
monitored, live elapsed timer, packet/device counts, and
"Listening..."/"Capturing" activity state.

- Repositioned progress indicator from right sidebar to a full-width
overlay at the top of the map panel
- Added animated spinning icon, glowing progress bar, blurred backdrop
- Centered layout with max-width constraint for readability
- Progress bar and status text more visible during active scans

The scanner and monitor are mutually exclusive (both need the SDR).
Previously auto-monitor tried to start mid-scan (causing device
conflicts) and required 3 towers (rarely achieved with weak signals).
Now after the first scan completes:
- If any towers were found, automatically stop scanner and start
grgsm_livemon + tshark on the strongest tower's ARFCN
- SDR handoff is clean (scanner process has already exited)
- If monitor fails to start, scanner loop resumes
- Scanner thread's finally block preserves SDR allocation when
monitor has taken over
- Frontend shows "Monitoring ARFCN X for devices..." status

- Forward scanner progress (%) and status to SSE stream
- Show progress bar and scan status in TRACKED TOWERS panel
- Send scan_complete event with tower count and duration
- Fix Europe BAND_CONFIG: only EGSM900 is recommended (GSM850/GSM800
are rarely used in Europe and waste scan time)
- DCS1800 available but not recommended (RTL-SDR sensitivity is lower)

Backend:
- Filter out CID=0 and MCC=0 entries (ARFCNs with no decoded cell identity)
Frontend:
- Move stats update before coordinate check so towers always counted
- Fix signal_strength display using null check instead of || (0 is falsy)
- Show operator name, frequency, and status in tower detail panel
- Show "Located" indicator in tower list for geocoded towers
- Fix selectTower crash when tower has no coordinates
- Update placeholder text to "Select a tower from the list"
- Add try/catch to selectTower for error resilience
Tests:
- Add tests for CID=0 and MCC=0 filtering

- Send all existing towers on SSE connect (fixes data loss on reconnect)
- Fix tower.signal -> tower.signal_strength field name in frontend
- Fix TypeError crash in selectTower when tower has no coordinates
- Add Connection: keep-alive header to SSE response
- Add comprehensive console.log debugging for SSE data flow
- Handle error/disconnected SSE event types in frontend

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

- 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.

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.

The Receiver Count section had no <h3> so it didn't get collapsible
panel styling, rendering as a small out-of-place rectangle. The count

The dmrRawOutput div was rendering garbled box-drawing characters from
the dsd-fme ASCII art banner below the signal activity canvas. Remove
the div and filter banner lines (box-drawing chars, version info) in
the parser so they never become events.

The DSD stderr parser had regex ordering bugs that swallowed voice and
call events as bare slot events, and only matched classic dsd output
format (not dsd-fme). Unmatched lines were silently dropped, leaving
the signal activity panel with nothing to display.
- Reorder regex checks: TG/Src before voice before slot
- Support dsd-fme comma-separated format (TG: x, Src: y)
- Make bare slot regex strict (only standalone "Slot N" lines)
- Forward unmatched DSD lines as raw events for diagnostics
- Add LISTENING state to signal activity panel for raw output
- Show raw decoder output text below synthesizer canvas
- Fix test mocks for find_dsd() tuple return value

Users can now manage decoded SSTV images with download and delete actions
accessible from hover overlays on gallery cards, the full-size image modal
toolbar, and a "Clear All" button in the gallery header. Both ISS and
General SSTV modes are supported.

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

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.
