# US-005: Deliver blocks and complete a quest
|
|
|
|
As a **player**, I want to deliver requested blocks to a quest board so that I receive the promised reward and the issuer can claim my delivery.
|
|
|
|
## Acceptance criteria
|
|
|
|
- [x] An active quest offers a Complete Quest action through every registered board.
|
|
- [x] Completion requires the delivering player to possess the full requested quantity of the exact block material.
|
|
- [x] Successful completion removes the requested blocks from the delivering player's inventory and stores them as a claim for the issuer.
|
|
- [x] Successful completion gives the exact escrowed reward items to the delivering player.
|
|
- [x] Reward items that do not fit are dropped safely at the delivering player's feet with a clear message.
|
|
- [x] The issuer is notified immediately when online or on their next login when offline that delivered blocks can be claimed at a quest board.
|
|
- [x] When player commands are enabled, `/quests complete <quest>` provides equivalent behavior with contextual autocomplete.
|
|
- [x] Completion is atomic and exactly one player can complete a quest, including simultaneous attempts.
|
|
- [x] Validation or persistence failure does not consume delivered blocks, release rewards, or change quest state.
|
|
- [x] Completed quests are no longer shown as active or completable.
|
|
- [x] Automated tests verify inventory validation, settlement, overflow, notifications, rollback, and concurrent completion protection.
