 # Spigot Quest Board
 
-A Purpur 26.2 plugin for shared physical quest boards. Players can escrow rewards for requested block items, deliver those blocks at any quest board, and claim delivered or returned items safely.
+A Purpur 26.2 plugin for shared physical quest boards. Players can escrow rewards for requested items, deliver those items at any quest board, and claim delivered or returned items safely.
 
 The approved behavior is specified in the [OKF knowledge bundle](knowledge/index.md).
 
 ## Status
 
-Administrators can register persistent shared quest boards by targeting a block within five blocks and running `/questadmin createboard`. They can instead run `/questadmin createboard physical` to generate a five-wide oak board above the targeted ground anchor and register its visible panel blocks and signs. Right-clicking any registered board opens a compact native dashboard with dedicated browsing, creation, and claim screens. A player can request a block and quantity while escrowing the exact reward stack held in their main hand. Every board and `/quests list` show the same active quests with requested blocks, rewards, issuers, and time remaining. Players can complete quests at any board or with `/quests complete <quest>` by delivering the required blocks. Exact escrowed rewards are granted immediately, and delivered blocks are held for the issuer. Issuers can cancel their own active quests at any board or with `/quests cancel <quest>`. Completed deliveries and rewards from cancelled or seven-day-expired quests are held durably and can be collected at any board or with `/quests claim`; inventory overflow drops at the claimant's feet.

+## 2026-09-10T01:38:21Z — Inventory-item quest requests
+
+- Extended [US-003](user-stories/us-003-create-a-block-delivery-quest.md) and [US-005](user-stories/us-005-deliver-blocks-and-complete-a-quest.md) to support inventory item materials, including shulker shells, rather than only blocks.
+- Validation and autocomplete use item eligibility and reject air and non-item materials; command, dialog, notification, and claim wording now describes items.
+- Preserved the persistence format and existing escrow, delivery, and claim transitions.
+- Confirmed catalog regressions failed before the fix using mocked server material properties, then verified shell creation, persisted settlement and claim acknowledgement, and existing regressions: all 134 tests and the plugin JAR passed `./gradlew clean check jar`.

 ## 2026-09-05 — Initial quest-board design
 
 - Administrators create physical quest boards, and every board exposes the same global quests and claims.
@@ -91,3 +98,38 @@ description: Chronological record of material decisions affecting Spigot Quest B
 - Registered all visible planks and signs in one durable operation and added obstruction checks plus block rollback when construction or persistence fails.
 - Preserved existing single-block board creation and persisted board compatibility.
 - Verified 103 tests and the plugin JAR with `./gradlew clean check jar`.
+
+## 2026-09-05 — Readable physical-board signage
+
+- Added centered `Quest Board` and right-click instruction signs on the two layers above each generated board's three decorative signs.
+- Registered all five signs and the plank face as shared-board interaction locations.
+- Added exact legacy-structure detection and failure-safe startup upgrades for previously generated three-sign boards without touching custom or altered structures.
+- Verified 111 tests and the plugin JAR with `./gradlew clean check jar`.
+
+## 2026-09-05 — Glowing readable board signs
+
+- Enabled glowing front-side text on generated title and instruction signs while retaining non-glowing decorative signs.
+- Added exact full-structure detection to refresh existing generated boards once without modifying custom or altered signs.
+- Added two-sign snapshot rollback when a refresh cannot complete safely.
+- Verified 116 tests and the plugin JAR with `./gradlew clean check jar`.
+
+## 2026-09-05 — Nearby command-based quest creation
+
+- Allowed `/quests create <block> <quantity>` and its material and quantity autocomplete within five blocks of any registered board location even while global player commands are disabled.
+- Kept listing, completion, cancellation, and claiming commands disabled under that setting while preserving global command behavior when enabled.
+- Enforced same-world Euclidean proximity with an inclusive five-block boundary for custom and generated boards.
+- Verified 121 tests and the plugin JAR with `./gradlew clean check jar`.
+
+## 2026-09-05 — Named reward identification
+
+- Displayed custom reward names together with their material type in shared board details and command listings, such as `1 × Shopping List (PAPER)`.
+- 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.
+- Verified 128 tests and the plugin JAR with `./gradlew clean check jar`.
+
+## 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`.
