# Spigot Tyrant Design Log
## 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.

- 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.

- [x] While the event is running, damage is cancelled when the Tyrant or an Assassin, Fixer, or Tamer attacks an opted-out player.

## Acceptance criteria
- [ ] Each item-triggered class ability uses a uniquely named standard Minecraft item with hidden persistent ownership and ability metadata.
- [ ] Right-clicking or swinging the appropriate item activates the ability without also performing an unsafe vanilla action.
- [ ] Another player cannot activate, retain, craft with, place, store, frame, dispense, or otherwise transfer a bound ability item.
- [ ] A cooldown ability item disappears only after successful activation and is restored when the cooldown finishes.
- [ ] The Tamer's named fishing rod has no cooldown and remains available after successful capture or placement.
- [ ] A dropped class ability item vanishes immediately; a dropped captured-mob item instead attempts to spawn its mob safely.
- [ ] `/tyrant item` restores currently available missing class items but cannot bypass cooldowns or create duplicates.
- [ ] Missing ready items are restored on login and cooldown completion when inventory space is available.
- [ ] When delivery fails because the inventory is full, no item is dropped and the player is told both why and how to use `/tyrant item` after making room.
- [ ] Bound class items are removed when a player loses the class or the Tyrant's reign ends.
- [ ] Death, inventory movement, server restart, repeated commands, and concurrent events cannot duplicate a bound item or its captured mob.
