 # Spigot Tyrant Design Log
 
+## 2026-08-18 — Preserve ordinary potion effects
+
+- Corrected Assassin effect maintenance so it refreshes active Tyrant abilities without removing invisibility, Speed, or Weakness supplied by potions, commands, or other plugins.
+- Expired or inapplicable Tyrant-managed effects stop refreshing and expire naturally within their short 30-tick maintenance duration, while double-jump flight cleanup remains immediate.
+- Reopened and completed US-005 with regression coverage; verified `./gradlew clean check jar`.
+
+## 2026-08-14 — Opt-out proximity glow completed
+
+- Extended US-011 with a globally visible green outline for opted-out players in the Tyrant's world and configured range while the event is running.
+- A periodic controller removes the glow when eligibility, proximity, world, lifecycle, or player availability changes and clears managed state on logout and shutdown.
+- Scoreboard presentation records and restores each player's previous team and glowing state instead of permanently replacing unrelated presentation.
+- Verified inclusive range behavior, lifecycle and availability gating, green presentation, restoration, and the full Gradle build.
+
+## 2026-08-14 — Opt-out proximity glow started
+
+- US-011 is reopened for a test-first green outline on opted-out players near the Tyrant during a running event, using the existing configurable Tyrant range.
+- Cleanup will cover range, world, participation, lifecycle, availability, shutdown, and restoration of pre-existing scoreboard-team membership.
+
+## 2026-08-14 — Join messaging refinement completed
+
+- Updated US-011 so join output no longer announces running, paused, or unstarted lifecycle state.
+- Eligible unassigned players now see the neutral prompt, `Use /tyrant optout if you do not want to participate in Tyrant events.`
+- Role, class, ability, cooldown, and existing opt-out details remain unchanged.
+- Verified both assigned and unassigned join output with automated tests.
+
+## 2026-08-14 — Join messaging refinement started
+
+- US-011 is reopened to remove lifecycle announcements from join output and make the opt-out prompt refer generally to Tyrant events.
+
+## 2026-08-14 — Opt-out combat protection completed
+
+- Extended US-011 with bidirectional combat isolation between opted-out players and the Tyrant, Assassin, Fixer, or Tamer while the event is running.
+- Direct player attacks and player-fired projectiles are cancelled at highest event priority, and the attacker is told that the target has chosen not to participate in the Tyrant event.
+- Paused, unstarted, and unrelated combat remains ordinary Minecraft gameplay.
+- Verified both attack directions, every Tyrant-side class, projectile attribution, lifecycle gating, and unrelated combat with automated tests.
+
+## 2026-08-14 — Opt-out combat protection started
+
+- US-011 is reopened for test-first running-event combat isolation between opted-out players and the Tyrant or Tyrant-side class holders.
+- Paused and unstarted gameplay remains ordinary Minecraft combat; blocked direct and projectile attackers receive a concise Tyrant event participation message.
+
+## 2026-08-14 — Tamer completed
+
+- Completed US-007 with the no-cooldown owner-bound Tamer's Lead, server-generated entity snapshots, durable capture IDs, and one bound Captured Mob item per entity.
+- Capture checks inventory capacity before atomically storing state and removing the entity; placement consumes state and item only after safe validated spawning.
+- Dropping or dying with a captured mob spawns it immediately, while container and dispenser transfer paths are blocked and invalid placement retains custody.
+- Ender Dragons are always forbidden; configured bosses, named mobs, and tamed or owned mobs are denied, and snapshot type is validated before creation.
+- Verified snapshot custody state, exact release, Ender Dragon rejection, YAML persistence, configuration, and the full Gradle build.
+
+## 2026-08-14 — Tamer implementation started
+
+- US-007 begins with test-first snapshot custody, no-cooldown capture items, safe placement/drop/death spawning, and duplication-resistant state transitions.
+
+## 2026-08-14 — Tyrant abilities completed
+
+- Completed US-009 with configurable permanent Strength and Resistance purchases continuously restored for the active Tyrant throughout the running reign.
+- Added `/tyrant intelligence` with a rolling configurable 24-hour unpaused cooldown and an aggregate count of the Vigilante plus assigned non-opted-out Followers without identities or locations.
+- Ability ownership and cooldowns remain visible in status output, persist across restart, and are cleared by existing reign succession cleanup.
+- Verified intelligence authorization, counts, cooldown persistence, effect configuration, and the full Gradle build.
+
+## 2026-08-14 — Tyrant ability implementation started
+
+- US-009 begins with test-first permanent effect ownership, automatic reapplication, and rolling-24-hour opposition roster intelligence.
+
+## 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 items completed
+
+- Completed US-014 with configurable named standard items carrying hidden owner and ability metadata, interaction cancellation, and owner-validated Assassin, Fixer, and Tamer activation.
+- Cooldown items are consumed only on successful use, restored automatically when ready or by `/tyrant item`, deduplicated, and withheld with clear guidance when inventory space is unavailable.
+- Drop, pickup, placement, crafting/storage movement, item-frame, dispenser, death, class loss, reign reset, login, and restart paths prevent transfer and duplication.
+- Captured-mob custody items use independent IDs, reconcile missing or duplicate inventory items against durable snapshots, and spawn rather than vanish on drop or death.
+- Verified readiness consumption and refresh, assignment cleanup, durable metadata state, captured custody, and the full Gradle build.
+
+## 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.
+- 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.
+- 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.
