Goal

An accidental Back press or a crash two hours into a ride must not lose the ride.

Acceptance criteria

Ride state, distance, moving time and start timestamp written to persist storage
Writes throttled so flash wear stays reasonable
On launch, an in-progress ride is detected and the user offered resume or discard
Verified by force-killing the app mid-ride in the emulator and on the watch
