- Stop active DB update work before tearing down executor pools.
- Short-circuit scan completion callbacks during shutdown so in-flight timer ticks don’t queue follow-up work.
- Prevent the download monitor from draining deferred/completed tasks after shutdown starts.
- Make listening stats startup stop-aware so it exits cleanly if teardown begins during warmup.
- If a metadata update is already running, it can now observe should_stop and exit cleanly instead of continuing after SIGTERM.
- Add interruptible stop events to background workers so shutdown
wakes out of long sleeps instead of waiting on fixed delays.
- Stop scan managers, repair worker, executors, and cleanup helpers
deterministically so process exit does not leave background threads
alive.
- Add startup warnings for stale SQLite WAL/SHM sidecars so unclean
shutdowns are easier to spot before init/migration errors cascade.
- Prevent forced kills from leaving SQLite sidecars behind, which
made rollbacks to older branches fail with malformed database
errors.
Stripped 4,200+ emoji characters from print(), logger calls across
39 Python files. Logs are now clean text — easier to grep, more
professional, no encoding issues on terminals without Unicode support.
Seasonal config icons preserved for UI display.
Introduces Docker deployment files (.dockerignore, Dockerfile, docker-compose.yml, docker-setup.sh, requirements-webui.txt, and README-Docker.md) for SoulSync WebUI. Refactors core/database_update_worker.py and core/media_scan_manager.py to support headless operation without PyQt6, enabling signal/callback compatibility for both GUI and non-GUI environments. Removes logs/app.log file.
