 # Spigot Tyrant Design Log
 
+## 2026-08-14 — Administrative lifecycle completed
+
+- Completed US-001 with permission-gated `/tyrantadmin` start, status, pause, resume, and confirmed reset operations.
+- Initial Vigilantes may be assigned explicitly or selected among eligible recently active players, with offline selections persisted as pending confirmations.
+- Pause/resume preserves progression and assignments, shifts every cooldown, participation, inactivity, and pending-selection deadline, and invokes managed effect suppression/restoration.
+- Added detailed operator status output and verified lifecycle, timer shifting, permissions, confirmation safety, candidate filtering, metadata, and effect hooks with the Gradle suite.
+
+## 2026-08-14 — Administrative lifecycle implementation started
+
+- US-001 begins with test-first game start, pause/resume deadline freezing, permission-gated administration, inspection, and confirmed reset behavior.
+
+## 2026-08-14 — Tyrant class assignment completed
+
+- Completed US-004 with `/tyrant assign <class> <player>`, purchased-class authorization, UUID state, one holder per class, and one Tyrant-side class per player.
+- Preserved dual alignment so Vigilantes and Followers can hold a Tyrant-side class, while rejecting the Tyrant and opted-out targets.
+- Added reassignment and reign cleanup for class cooldown/item state, online assignment/removal notices, and login control reminders.
+- Verified assignment constraints, dual alignment, cleanup, commands, notifications, and reminders with the Gradle test suite.
+
+## 2026-08-14 — Tyrant class assignment implementation started
+
+- US-004 begins with test-first purchased-class authorization, one-holder constraints, dual alignment, reassignment cleanup, and reign-wide removal.
+
 ## 2026-08-14 — Tyrant progression completed
 
 - Completed US-003 with exact Tyrant-on-Vigilante kill attribution, level and choice rewards, pause guards, one-time purchases, and reign reset behavior.

 ## Acceptance criteria
 
-- [ ] An administrator can start the first game by assigning the initial Tyrant.
-- [ ] The administrator may assign the first Vigilante or allow random selection from eligible recently active players.
-- [ ] An administrator can pause and resume the game without deleting game state.
-- [ ] Pausing freezes progression, cooldowns, daily-use timers, inactivity checks, and pending-selection deadlines.
-- [ ] Role and class effects are suppressed while paused and restored when play resumes.
-- [ ] Administrative commands require the `spigottyrant.admin` permission, granted to server operators by default.
-- [ ] Administrators can inspect lifecycle state, roles, classes, Followers, purchases, levels, cooldowns, participation, and pending selections.
-- [ ] Destructive administrative operations require explicit confirmation.

 ## Acceptance criteria
 
-- [ ] The Tyrant can assign only Assassin, Fixer, and Tamer classes purchased during the current reign.
-- [ ] Each class can be assigned to at most one player at a time, and a player can hold at most one Tyrant-side class.
-- [ ] Role alignment and Tyrant-side class are independent: the Vigilante or a Follower may simultaneously be the Assassin, Fixer, or Tamer.
-- [ ] The Tyrant cannot assign a class to the Tyrant, an opted-out player, or another ineligible player.
-- [ ] Reassignment removes the class and its bound items and effects from the previous holder before granting it to the new holder.
-- [ ] Assignment and removal are stored by UUID and communicated clearly to affected players.
-- [ ] A class holder is reminded of the assignment and its controls on login.
-- [ ] All class assignments end when the Tyrant's reign ends.
