+  Pre-request resets grid contract progress and prototype faction standing (stale state from prior seq 11 runs), then marks operator chain completed via POST …/__dev/quest-fixture (no rep delivery; standing 0). Quest fixture resetQuestIds also clears reward delivery + audit rows for reset quests.
   Success sibling: seq 11 Accept grid contract after operator chain (NEO-138 organic rep grant).

 3. ~~**Document auto-complete on grid-contract accept in tests/README.** Integration test name says “Accept” but the meaningful gate check is standing ≥ 15; the returned snapshot is **`completed`** because the kit is already in inventory. A one-line comment in `QuestStateOperationsTests` and Bruno **docs** block would prevent future “active vs completed” confusion.~~ **Done.** Comment in `QuestStateOperationsTests`; Bruno docs block updated.
 4. ~~**Optional: multi-row rep deny rollback test.** Plan lists rep deny after items with audit append failure on the second rep row; only **`unknown_faction`** rollback is covered today. Consider a store stub that fails **`TryAppend`** on the second row to lock compensating rollback across grant types.~~ **Done.** `TryDeliverQuestCompletion_ShouldRollbackAllGrants_WhenSecondReputationAuditAppendFails` with forward-rep-only audit stub.
+5. ~~**Bugbot: fixture reset skips delivery store.** `resetQuestIds` cleared quest progress and faction standing but not **`IRewardDeliveryStore`** / audit rows, so repeated Bruno runs skipped rep re-apply via idempotent delivery (and duplicate audit ids).~~ **Done.** `resetQuestIds` clears delivery + quest-completion audit rows.
