 - Stored safe plain-text custom names alongside unchanged exact item metadata and inferred names from valid historical escrow data when possible.
 - Kept malformed or unavailable metadata from blocking quest browsing by falling back to material descriptions.

+## 2026-09-07T01:31:27Z — Login quest guidance and recurring claim reminders
+
+- Extended [US-004](user-stories/us-004-browse-available-quests.md) with a private active, unexpired quest count on every login and guidance to visit the quest board to accept or create a quest.
+- Extended [US-007](user-stories/us-007-expire-quests-and-claim-held-items.md) with reminders on every login while actual pending claims remain, independently of notification acknowledgement and across reloads.
+- Preserved existing real-time and durable notifications without changing claim storage or collection.
+- Confirmed new behavior tests failed before implementation, then verified all 130 tests and the plugin JAR with `./gradlew clean check jar`.
