 # Spigot Tyrant Design Log
 
+## 2026-08-14 — Fixer completed
+
+- Completed US-006 with the named owner-bound Fixer's Wrench, one-hour cooldown, and ten-minute Strength and Health Boost activation.
+- Activation records a fixed normal two-row or near-Tyrant three-row heart tier using same-world configurable proximity at use time.
+- Continuously refreshed effects survive death, login, milk, and ordinary removal; expiry and class loss remove effects and clamp health safely to the resulting maximum.
+- Verified activation tiers, active and cooldown deadlines, item consumption/readiness, persistence, and the full Gradle build.
+
+## 2026-08-14 — Fixer implementation started
+
+- US-006 begins with test-first bound-item combat boosts, activation-time proximity tiers, persistent cooldowns, and safe health cleanup.
+
+## 2026-08-14 — Assassin completed
+
+- Completed US-005 with named owner-bound Assassin Cloak activation, one-hour cooldown, particle-free ten-minute invisibility, and activation-time doubling within the Tyrant's configurable range.
+- Added 60-second double-jump gating, upward launch, 15-second Speed, 20-second Weakness III, and grounded readiness restoration.
+- Active effects and cooldowns persist as UTC deadlines and are continuously restored after death, login, milk, or ordinary removal while valid.
+- Verified duration tiers, cooldown consumption and refresh, jump effect deadlines, class constraints, persistence, and the full Gradle build.
+
+## 2026-08-14 — Assassin implementation started
+
+- US-005 begins with test-first bound-item invisibility, near-Tyrant duration doubling, and cooldown-gated double-jump effects.
+
+## 2026-08-14 — Bound ability item implementation started
+
+- US-014 begins with test-first item readiness and recovery, owner metadata, transfer prevention, cooldown redelivery, and Tamer item permanence.
+
+## 2026-08-14 — Vigilante and Followers completed
+
+- Completed US-008 with `/vigilante` invitation, acceptance, dismissal, and leave flows while preserving independent Tyrant-side class assignments.
+- Added Tyrant/Vigilante combat tracking and continuously refreshed Strength and Resistance based on living same-world Followers within the configurable 50-block range, capped at Strength V and Resistance IV by default.
+- Every Vigilante death now awards progression only to the Tyrant killer, clears Followers, and applies normal recently-active replacement with previous-holder fallback.
+- Verified membership, dual alignment, scaling and caps, role maintenance, command metadata, and death/progression components with the Gradle suite.
+
+## 2026-08-14 — Vigilante and Follower implementation started
+
+- US-008 begins with test-first invitation membership, death reroll and Tyrant reward integration, combat tracking, and proximity-scaled capped effects.
+
+## 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.
+
+## 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.
