+- Completed US-014 with configurable named standard items carrying hidden owner and ability metadata, interaction cancellation, and owner-validated Assassin, Fixer, and Tamer activation.
+- Cooldown items are consumed only on successful use, restored automatically when ready or by `/tyrant item`, deduplicated, and withheld with clear guidance when inventory space is unavailable.
+- Drop, pickup, placement, crafting/storage movement, item-frame, dispenser, death, class loss, reign reset, login, and restart paths prevent transfer and duplication.
+- Captured-mob custody items use independent IDs, reconcile missing or duplicate inventory items against durable snapshots, and spawn rather than vanish on drop or death.
+- Verified readiness consumption and refresh, assignment cleanup, durable metadata state, captured custody, and the full Gradle build.

 ## Acceptance criteria
 
-- [ ] Each item-triggered class ability uses a uniquely named standard Minecraft item with hidden persistent ownership and ability metadata.
-- [ ] Right-clicking or swinging the appropriate item activates the ability without also performing an unsafe vanilla action.
-- [ ] Another player cannot activate, retain, craft with, place, store, frame, dispense, or otherwise transfer a bound ability item.
-- [ ] A cooldown ability item disappears only after successful activation and is restored when the cooldown finishes.
-- [ ] The Tamer's named fishing rod has no cooldown and remains available after successful capture or placement.
-- [ ] A dropped class ability item vanishes immediately; a dropped captured-mob item instead attempts to spawn its mob safely.
-- [ ] `/tyrant item` restores currently available missing class items but cannot bypass cooldowns or create duplicates.
-- [ ] Missing ready items are restored on login and cooldown completion when inventory space is available.
-- [ ] When delivery fails because the inventory is full, no item is dropped and the player is told both why and how to use `/tyrant item` after making room.
-- [ ] Bound class items are removed when a player loses the class or the Tyrant's reign ends.
-- [ ] Death, inventory movement, server restart, repeated commands, and concurrent events cannot duplicate a bound item or its captured mob.
