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.

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.
