- the problem: my movie library on several drives, moves that half-finish, no undo
- the rule I set: never delete a file unless the user explicitly asks
- journal first: write every planned step to SQLite before touching the disk
- the copy: pipelined reader/writer, flush, read back past the OS cache, compare SHA-256
- the switch: staging folder → one rename → library points at the new place
- originals to the recycle bin / freedesktop trash (rename-only, never copied)
- undo from history, and what happens after a crash mid-move
- try it / contribute: https://github.com/mustafayevt/CineVault
