Test a reservation retry.
A slow response makes someone click twice. Reproduce the retry and check what the booking service creates.
A repeatable duplicate-request test and a reviewable fix.
Use this starter prompt
In [repository], reproduce [reservation retry issue] with a sandbox property. Test double submission, a timeout after creation, replayed requests, and cancellation during retry. Follow [reservation rules], add regressions, and report the results. Do not create real reservations, change rates, or deploy.
