 ## Status
 
-Administrators can register persistent shared quest boards by targeting a block within five blocks and running `/questadmin createboard`. Right-clicking any registered board opens a native dialog where 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.

+## 2026-09-05 — Screen-fitting quest-board dialogs
+
+- Replaced the clipped 800-pixel combined board screen with a compact 420-pixel dashboard.
+- Split browsing, creation, and claims into dedicated native dialog screens with Back navigation.
+- Presented active quests as individual detail dialogs while retaining completion and issuer cancellation actions.
+- Verified 88 tests, including a 250-quest navigation case, and the plugin JAR with `./gradlew clean check jar`.
+
+## 2026-09-05 — Generated physical quest boards
+
+- Added `/questadmin createboard physical` to generate a five-wide, four-tall board above the targeted ground anchor facing the administrator.
+- Used oak-log pillars, an oak-plank face, and three oak wall signs with obfuscated decorative text.
+- 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`.

+# US-009: Use a screen-fitting quest-board interface
+
+As a **player**, I want the quest-board interface to fit on screen so that I can read quest information and reach every action.
+
+## Acceptance criteria
+
+- [x] The oversized combined dialog is replaced by a compact dashboard.
+- [x] Dialog message bodies use a maximum width of 420 pixels.
+- [x] Browsing, quest creation, and pending claims use dedicated screens rather than one combined body.
+- [x] Active quests are presented as individual navigable entries instead of one unbounded text listing.
+- [x] Each quest detail shows its issuer, requested material and quantity, reward, and time remaining.
+- [x] Completion, issuer-only cancellation, creation, and claim collection remain available through the board.
+- [x] Nested screens provide Back controls that return toward the quest-board dashboard.
+- [x] Large active-quest collections remain navigable without producing an unbounded single dialog.
+- [x] Automated tests verify width limits, screen separation, navigation, displayed content, and action routing.

+
+As an **administrator**, I want quest-board creation to optionally construct a recognizable physical board so that I do not need to build each board manually.
+
+## Acceptance criteria
+
+- [x] `/questadmin createboard physical` generates and registers a physical quest board while the existing `/questadmin createboard` behavior remains unchanged.
+- [x] The targeted block is treated as the ground anchor and remains unchanged.
+- [x] The generated board faces the administrator and is five blocks wide and four blocks tall.
+- [x] The outer columns use oak-log pillars and the center uses oak planks.
+- [x] Oak wall signs on the front display decorative obfuscated or gibberish text.
+- [x] Clicking generated visible planks or signs opens the same globally shared quest-board interface.
+- [x] Generation requires empty space and refuses to overwrite an existing structure.
+- [x] Structure generation and interaction-location registration form one failure-safe transaction; failure restores changed blocks and registers nothing.
+- [x] Generated interaction locations persist across restarts and remain compatible with existing registered boards.
+- [x] The `physical` argument is offered through permission-aware command autocomplete.
+- [x] Automated tests verify geometry, facing direction, obstruction handling, rollback, registration, persistence, and autocomplete.
