Technical notes
Implementation
- Normalizes camera times and rejects interpolation across unsafe GPX gaps.
- Runs batches outside the UI thread with safe cancellation points.
- Stores saved-trip data locally; personal photos stay on the computer.
- Release includes 42 automated tests and a separate SHA-256 checksum.
Queue
Next
- Test-build feedback and stable-release checklist.
- Additional photo formats without weakening original-file safety.
- Code signing if future distribution justifies the cost.
