dmg 8e2d86b2cc feat(spawn): migrate distribution to Java 25 and Purpur
Release / release (push) Successful in 4m20s
CI / build (push) Successful in 1m16s
BREAKING CHANGE: New releases require Java 25/Purpur 26.2 and use purpur-trigger-spawn-<version>.jar. Runtime TriggerSpawn identity, persisted progression/cooldowns and world spawn settings remain unchanged. Replace the old JAR rather than installing both distributions.

# purpur-trigger-spawn agent entrypoint
The canonical stories, engineering guidance, and **all process documents** are in the private [SoMC OKF wiki](https://git.garvis.dev/dmg/somc-okf/src/branch/main/index.md).
Before work, read the sibling `../somc-okf/index.md`, `../somc-okf/processes/index.md`, `../somc-okf/projects/purpur-trigger-spawn/index.md`, `engineering.md` in that project section, and relevant `../somc-okf/user-stories/purpur-trigger-spawn/` stories. Also follow the parent workspace `AGENTS.md` when present.
For standalone checkouts, start at the [project page](https://git.garvis.dev/dmg/somc-okf/src/branch/main/projects/purpur-trigger-spawn/index.md) and [shared process](https://git.garvis.dev/dmg/somc-okf/src/branch/main/processes/development.md). Obtain wiki access before feature work; do not recreate a local knowledge bundle. Source builds do not require private wiki access.
Development follows [Development cycle](https://git.garvis.dev/dmg/somc-okf/src/branch/main/runbooks/development-cycle.md): approved stories, failing tests, passing implementation, verification, then source/wiki commit and push. GitOps updates are committed locally **without pushing**; only [Do release](https://git.garvis.dev/dmg/somc-okf/src/branch/main/runbooks/do-release.md) authorizes a reviewed GitOps push.

# Trigger Spawn
# Purpur Trigger Spawn
A Spigot 26.2 plugin providing progression-gated, safe teleportation to each world's spawn area.
A Purpur 26.3 plugin providing progression-gated, safe teleportation to each world's spawn area.
Players unlock `/spawn` by killing a Warden, Ender Dragon, or Wither after the plugin is installed. Their first, second, and third unique kills give default cooldowns of 8 hours, 4 hours, and 1 hour respectively. Each new unique kill clears the current cooldown immediately; repeated kills of the same boss do not count.
`/spawn` uses real elapsed cooldown time, including time offline. An accepted request displays a three-second countdown. Walking to another block, jumping, falling, teleporting, changing worlds, or disconnecting cancels it; looking around does not. The plugin samples a safe destination in the current world's circular spawn area, and failures do not consume the cooldown.
The behavior under development is specified in the [OKF design bundle](design/index.md).
The behavior under development is specified in the [SoMC OKF wiki](https://git.garvis.dev/dmg/somc-okf/src/branch/main/projects/purpur-trigger-spawn/index.md).
## Requirements
- Spigot 26.2
- Java 17 or newer
- Purpur 26.3 build 2651
- Java 25
The automated native lifecycle boundary downloads that exact runtime and accepts it only with
SHA-256 `0677c1febecfbc2e5b0a7f76abd647b70a1f38d3cbdf3dd6a82e401b4262a598`.
Repository, checkout and new artifacts use `purpur-trigger-spawn`. Runtime `TriggerSpawn`, Java entrypoint/packages, `plugins/TriggerSpawn/`, commands/permissions, boss progression, cooldowns and world spawn settings remain unchanged. Replace the old JAR rather than installing both distributions. Old tags/assets remain available; new releases no longer support Java 17.

The plugin JAR is written to `build/libs/`.
The plugin JAR is written to `build/libs/purpur-trigger-spawn-<version>.jar`.
`check` includes `nativeLifecycleTest`: it checksum-verifies Purpur 26.3 build 2651, prepares the
runtime in Paperclip patch-only mode, and loads, enables, and disables the packaged plugin through
Purpur's native JavaPlugin lifecycle. The isolated test verifies command/listener wiring, retained
configuration and YAML state without starting a listening server, accepting the EULA, or creating a
world. Scheduler, teleport, safe-location, world-border, persistence, metadata, bytecode, and JAR
exclusion regressions run alongside that boundary; this is automated compatibility evidence, not a
live-server or deployment claim.

# Trigger Spawn Design Log
## 2026-08-08 — Initial user stories
- Target Spigot 26.2 and Java 17 with a Gradle and Gitea Actions pipeline modeled on `spigot-event-producer`.
- Unlock `/spawn` after the first observed Warden, Ender Dragon, or Wither kill.
- Use real elapsed time for cooldowns, with defaults of eight, four, and one hour as unique boss kills accumulate.
- Support administrator-defined cooldown grants, complete access resets, and bans.
- Maintain a separate circular spawn area in each world, with a default radius of 20 blocks and safe randomized destinations.
- Require a stationary three-second warm-up that is cancelled by walking to another block, jumping, falling, teleportation, or world changes.
## 2026-08-08 — Progression reminders and rewards
- Remind players with incomplete progression that remaining unique boss kills permanently reduce the `/spawn` cooldown.
- Clear the active cooldown immediately after each newly credited unique boss kill.
- When cooldown prevents `/spawn`, explicitly report that it is unavailable and show the remaining wait in a friendly format.
## 2026-08-08 — Build and release foundation
- Added the Java 17 Gradle project targeting Spigot API 26.2, with JUnit 5 verification and versioned resource processing.
- Added Gitea CI and semantic-release workflows modeled on `spigot-event-producer`.
- Documented local builds, public releases, and the required `RELEASE_TOKEN` repository secret.
## 2026-08-08 — Configuration and persistence
- Added validated, independently configurable real-time cooldown tiers with documented defaults.
- Added atomic YAML persistence for UUID-based player access state and per-world spawn settings.
- Invalid persisted access values fail closed, while invalid required configuration disables the plugin rather than allowing partial startup.
- Added friendly duration formatting and the administrative permission declaration.
## 2026-08-08 — Per-world spawn areas
- Added `/spawnadmin set`, `distance`, and `info` for player-operated configuration of the current world.
- Worlds default to their native spawn and an independently persisted 20-block radius.
- Circular target sampling is uniform by area, preserves configured facing, and supports a zero-block radius.
## 2026-08-08 — Administrative access grants
- Added custom `/spawn` cooldown grants with safe, friendly duration parsing.
- Added complete access resets and a paginated view of naturally and administratively eligible players.
- Administrative targets resolve online players, persisted names, server-known offline players, and known UUIDs while state remains keyed by UUID.
## 2026-08-08 — Spawn bans
- Added persistent `/spawn` bans, unbans, and paginated ban listing for online and resolvable offline players.
- Banning immediately clears grants, boss progress, and cooldown state; unbanning restores none of them.
- Banned player state cannot retain natural or granted access.
## 2026-08-08 — Boss progression
- Added player-attributed Warden, Ender Dragon, and Wither kill observation without importing historical accomplishments.
- Unique kills unlock and improve the configured cooldown tier in any order; duplicate kills do not count.
- Each credited kill persists UUID-based progress, clears the current cooldown, and displays an on-screen reward plus colored checklist.
## 2026-08-08 — Safe spawn teleportation
- Added `/spawn` eligibility and real-time cooldown enforcement with explicit friendly remaining-time messages.
- Added a three-second on-screen warm-up cancelled by block movement, jumping, falling, teleportation, world changes, or disconnects.
- Safe destinations are sampled within the current world's circle using bounded attempts and a closest-elevation search that rejects environmental hazards.
- Only completed teleports consume cooldown, and incomplete progression receives a post-teleport reminder.
## 2026-08-08 — Progression rewards and reminders
- Successful `/spawn` teleports now identify each remaining boss and show the next permanent boss-based cooldown tier.
- Fully progressed players receive no unnecessary reminder.
- Verified that newly credited unique kills make `/spawn` immediately available while duplicate kills preserve the existing cooldown.

# US-001: Earn progressive spawn access
As a **player**, I want to unlock `/spawn` by defeating major enemies so that my progression earns increasingly convenient access to spawn.
## Acceptance criteria
- [x] The plugin observes player-attributed kills of the Warden, Ender Dragon, and Wither.
- [x] Only kills observed while the plugin is operating count; historical statistics and advancements are not imported.
- [x] The three enemies may be killed in any order.
- [x] The first unique qualifying kill unlocks `/spawn` with the configured one-kill cooldown, which defaults to 8 hours.
- [x] The second unique qualifying kill applies the configured two-kill cooldown, which defaults to 4 hours.
- [x] The third unique qualifying kill applies the configured three-kill cooldown, which defaults to 1 hour.
- [x] Repeated kills of an already credited enemy do not improve the player's tier.
- [x] Each newly credited kill displays an on-screen message stating that `/spawn` has been unlocked or updated, is immediately available, and has the shown applicable cooldown.
- [x] Progress is presented as a checklist in which credited enemies have a green check and uncredited enemies have a red cross.
- [x] Each newly credited unique kill immediately clears any active `/spawn` cooldown as a progression reward.
- [x] Progress is associated with the player's UUID and survives server and plugin restarts.

# US-002: Teleport safely to spawn
As an **eligible player**, I want `/spawn` to take me safely to my current world's spawn area so that I can return without exposing myself to an unsafe destination.
## Acceptance criteria
- [x] `/spawn` is available after at least one qualifying unique enemy kill or an administrative grant.
- [x] A player without access receives a message instructing them to defeat a Warden, Ender Dragon, or Wither and sees the colored progress checklist.
- [x] A banned player cannot begin a spawn teleport.
- [x] When an active cooldown prevents `/spawn`, the player is explicitly told that the command is unavailable and sees the remaining wait in a friendly duration format.
- [x] Cooldowns use real elapsed time and therefore continue while the player is offline.
- [x] An accepted teleport request starts a three-second on-screen countdown.
- [x] The player may look around during the countdown without cancelling it.
- [x] A change to the player's block X, Y, or Z coordinate cancels the countdown, including walking to another block, jumping, or falling.
- [x] Teleportation or a world change during the countdown cancels it.
- [x] The destination is sampled randomly within the circular spawn area configured for the player's current world.
- [x] The destination provides non-hazardous solid ground, two blocks of clear headroom, and no immediate lava, fire, water, void, or other configured environmental hazard.
- [x] Unsafe underwater, leaf-top, inaccessible Nether-roof, and void-exposed destinations are rejected.
- [x] The safe search prefers a valid vertical position closest to the configured spawn center's elevation rather than automatically preferring the world's highest surface.
- [x] The safe-location search uses a bounded number of attempts and reports failure clearly when no destination is found.
- [x] Only a completed teleport starts the applicable cooldown.
- [x] After a completed teleport, a player with unfinished boss progression is reminded that defeating each remaining unique boss permanently reduces the cooldown.
- [x] A cancelled countdown or failed safe-location search does not consume the cooldown.

# US-003: Configure each world's spawn area
As a **server administrator**, I want to configure the spawn area independently in each world so that `/spawn` sends players to an appropriate safe area in their current world.
## Acceptance criteria
- [x] Every world has an independent spawn center and maximum spawn distance.
- [x] Until an administrator sets a custom center, a world uses its native world spawn point.
- [x] `/spawnadmin set` stores the executing administrator's current world, coordinates, yaw, and pitch as that world's center and facing direction.
- [x] `/spawnadmin distance <blocks>` sets the current world's maximum spawn distance in blocks.
- [x] `/spawnadmin info` displays the current world's effective center, whether it is native or custom, and maximum distance.
- [x] The default maximum spawn distance is 20 blocks.
- [x] The spawn area is circular, and random horizontal points are sampled uniformly by area within its radius.
- [x] A maximum distance of `0` targets the configured center and adjusts it to the nearest safe block.
- [x] Negative, non-numeric, or otherwise invalid distances are rejected with an explanatory message.
- [x] Random destinations use the center's saved yaw and pitch.
- [x] Per-world centers and distances survive server and plugin restarts.

- [x] Killing qualifying enemies does not replace an active administrative grant's custom cooldown.
- [x] `/spawnadmin remove <player>` removes any administrative grant, recorded enemy progress, and active cooldown from the player.
- [x] After removal, the player begins with no access and can earn it again by defeating a qualifying enemy.
- [x] `/spawnadmin access [page]` lists all players who currently have natural or granted access, including offline players.
- [x] Each access-list entry identifies the player, access source, applicable cooldown, progression tier when relevant, and current remaining cooldown.
- [x] Administrative player arguments support online players and previously known offline players when they can be resolved safely.
- [x] Player state is stored by UUID while retaining the latest known player name for display and lookup.

- [x] Ordinary players do not require a plugin permission node to execute `/spawn`; eligibility is controlled by progression, grants, cooldowns, and bans.
- [x] Administrative commands require `triggerspawn.admin`.
- [x] Server operators receive `triggerspawn.admin` by default.
- [x] Boss progress, grants, bans, cooldown timestamps, latest known names, and per-world spawn settings persist across clean restarts.
- [x] Persisted data is handled defensively so corrupt or invalid records do not silently grant access.

# US-007: Build and release the plugin
As a **plugin maintainer**, I want automated builds and releases so that tested, correctly versioned plugin artifacts can be distributed consistently.
## Acceptance criteria
- [x] The Gradle project compiles against Spigot API `26.2-R0.1-SNAPSHOT` using a Java 17 toolchain.
- [x] Automated JUnit 5 tests run as part of the Gradle check lifecycle.
- [x] Pushes and pull requests build and test the plugin in Gitea Actions.
- [x] Pull requests validate conventional commit messages.
- [x] CI stores a development JAR as a workflow artifact.
- [x] Main-branch conventional commits drive semantic versioning.
- [x] A successful release builds a versioned JAR and attaches it to the corresponding Gitea release.
- [x] The build and release workflow follows the established `spigot-event-producer` project pattern where applicable.

description: Remind players how to improve spawn access and reward each newly credited unique boss kill with an immediate cooldown reset.
status: done

# US-008: Reward and encourage spawn progression
As a **player**, I want `/spawn` to explain how I can improve its cooldown and reward new boss progress so that the benefit of defeating each remaining boss is clear and immediately useful.
## Acceptance criteria
- [x] After every successful `/spawn`, a player who has not defeated all three unique qualifying enemies receives a reminder that defeating the remaining bosses permanently reduces the cooldown.
- [x] The reminder identifies the remaining eligible bosses and shows the next cooldown tier.
- [x] A player who has completed all three unique qualifying kills does not receive the progression reminder.
- [x] Each newly credited unique Warden, Ender Dragon, or Wither kill immediately clears the player's active `/spawn` cooldown.
- [x] Clearing the cooldown makes `/spawn` immediately available as a progression reward.
- [x] The newly credited kill also permanently applies the improved boss-based cooldown tier.
- [x] Repeated kills of an already credited enemy do not clear the cooldown.
- [x] The on-screen kill message states that `/spawn` is immediately available and displays the new cooldown tier.
- [x] Banned players cannot earn kill credit, a cooldown reset, or an improved tier.
