 # Spigot Tyrant Design Log
 
+## 2026-08-14 — Participation completed
+
+- Completed US-011 with `/tyrant status`, `optout`, `optin`, and confirmed `relinquish` flows plus comprehensive join messages for lifecycle, roles, classes, abilities, and cooldowns.
+- Opt-out clears ordinary classes and Follower membership, persists until the player explicitly opts back in, and enforces the configurable seven-day unpaused waiting period.
+- Central role holders must safely relinquish first; Tyrant relinquishment performs full succession and Vigilante relinquishment performs a normal Vigilante reroll.
+- Updated all assignment and candidate paths to exclude opted-out players and verified status, persistence, cleanup, cooldown, and relinquishment behavior with the Gradle suite.
+
+## 2026-08-14 — Participation implementation started
+
+- US-011 begins with test-first opt-out/opt-in state, seven-day re-entry gating, safe role relinquishment guidance, and complete join status messages.
