 # Spigot Tyrant Design Log
 
+## 2026-08-14 — Role maintenance completed
+
+- Completed US-010 with configurable periodic role maintenance, exact 48-hour inactivity handling, and 24-hour recently-active candidate filtering.
+- Added online confirmation for pending roles, 24-hour expiry and reroll, former-holder fallback rules, vacant-role retries, opt-out filtering, and Tyrant/Vigilante conflict prevention.
+- Tyrant inactivity uses full reign succession cleanup; Vigilante inactivity clears only that role's Followers before replacement.
+- Verified confirmation, expiry reroll, Follower cleanup, exact inactivity boundary, full Tyrant succession, and pause-safe scheduler integration with the Gradle suite.
+
+## 2026-08-14 — Role maintenance implementation started
+
+- US-010 begins with test-first inactivity replacement, pending confirmation and expiry, conflict-safe candidate retries, and pause awareness.
+
+## 2026-08-14 — Tyrant succession completed
+
+- Completed US-002 with player-killer transfer, recent-player environmental succession, former-holder avoidance, pending offline confirmation, and distinct replacement Vigilante selection.
+- Tyrant death clears all classes, Followers, cooldowns, item readiness, purchases, levels, and choices before granting the successor one starting choice.
+- Added death-event integration, server announcements, and a scoreboard-team-backed red Tyrant name and glowing outline that is restored on login and removed on pause or shutdown.
+- Verified succession attribution, random exclusion, reign cleanup, role separation, death integration, and red presentation with the Gradle suite.
+
+## 2026-08-14 — Tyrant succession implementation started
+
+- US-002 begins with test-first killer and environmental succession, reign-wide cleanup, replacement Vigilante selection, and red Tyrant presentation.
+
 ## 2026-08-14 — Administrative lifecycle completed
 
 - Completed US-001 with permission-gated `/tyrantadmin` start, status, pause, resume, and confirmed reset operations.
