What stays compatible

BurrowTime targets Watson 2.1.0 command behavior and preserves theconfig, frames, state, andlast_sync formats. Its agent and concurrent-timer metadata lives in separate companion files.

Move from Watson

On first interactive use, BurrowTime offers to copy a detected Watson installation. Watson's files are not moved or edited. You can run the same migration later:

burrowtime migrate from-watson

If BurrowTime already has data, it confirms replacement and creates a timestamped backup.

Move back to Watson

burrowtime migrate to-watson

Watson can represent one active timer. BurrowTime refuses the export while extra concurrent timers are running, and it does not copy the companion agent or concurrency files.

Migration is a snapshot, not a sync. Activity recorded after a copy does not automatically appear in the other program.

Use custom directories

burrowtime --data-dir /path/to/burrowtime \
  migrate from-watson --watson-data-dir /path/to/watson

burrowtime --data-dir /path/to/burrowtime \
  migrate to-watson --watson-data-dir /path/to/watson --force

The compatibility executable

Release archives also contain watson. It keeps Watson's original data-directory behavior and non-interactive bare command for users who want a direct Go-based replacement.
