-# AGENTS.md — Arena Mod
-
-## Mission
-Build a server-first NeoForge 1.21.1 PvE arena mod. The mod must remain usable without Cobblemon, EasyNPC, Create, or any boss mod.
-
-## Working rules
-1. `SPEC.md` is the functional source of truth. `ARCHITECTURE.md` is the technical source of truth.
-2. Work only on the current unchecked phase in `TODO.md`, unless explicitly asked otherwise.
-3. Inspect the existing project and dependency versions before coding. Never invent an API.
-4. For optional integrations (Cobblemon/EasyNPC/third-party entities), verify the actual installed API/source before writing integration code.
-5. Keep optional integrations isolated; absence of an optional mod MUST NOT prevent startup.
-6. Prefer Minecraft/NeoForge registries and resource IDs (`namespace:path`) over hard-coded vanilla lists.
-7. Content must be data-driven where specified. Invalid content disables only the affected definition and produces a useful diagnostic; it must not crash the server.
-8. Inventory safety is critical. Never clear a player's original inventory until its recovery snapshot has been durably persisted.
-9. Avoid unrelated refactors. Keep commits/changes scoped and easy to review.
-10. Compile/test after each phase. Fix compilation errors before declaring a phase complete.
-11. Add focused tests where practical, especially for pure logic (wave budgeting, rank thresholds, validation, state transitions).
-12. If implementation must diverge from these docs, document the reason in `ARCHITECTURE.md` before proceeding.
-13. Update `TODO.md` only for work actually completed.
-
-## Definition of done for a phase
-- Project compiles.
-- Existing tests still pass.
-- New behavior has a minimal test or reproducible manual test procedure.
-- No optional dependency became mandatory.
-- No known inventory-loss/duplication path was introduced.
-- `TODO.md` reflects reality.

-# Architecture — NeoForge 1.21.1 Arena
-
-This document fixes responsibilities, not exact Java package names.
-
-## Modules/components
-### ArenaManager
-Owns registered arena definitions/controllers and active sessions. V1 may enforce one active arena, but APIs should accept arena/session IDs.
-
-### ArenaDefinition / ArenaControllerBlockEntity
-Persistent spatial configuration: relative bounds, locations, tagged spawn points, water baseline/max, presentation/config metadata. Controller is the coordinate origin.
-
-### ArenaSession
-Runtime state machine. Holds immutable starting roster/config snapshot plus mutable participant states, wave state, lives, tracked entities, environment transaction and reward progress.
-
-### ParticipantState
-UUID, class, ready/eliminated status, remaining arena kit state, reputation progress, recovery reference.
-
-### InventoryRecoveryService
-Durable, idempotent recovery snapshots. Owns save-before-clear, restore-on-exit/login, unfinished-session recovery and anti-duplication state transitions. Keep this isolated and heavily tested.
-
-### ContentRepository
-Loads/reloads/validates JSON definitions: classes, ranks, themes, mob variants, bosses, progression/balance config. Registry-aware validation produces diagnostics and disabled-definition lists.
-
-### ItemStackCodec / CaptureService
-Uses Minecraft's supported ItemStack serialization/data-component mechanisms for target version. In-game capture normalizes durability only, preserves stack count and other components, then writes canonical JSON.
-
-### WaveDirector
-Pure-ish deterministic logic where possible. Inputs: wave index, target budget, eligible themes, recent theme history, player scaling, RNG seed. Output: planned composition. Does not directly spawn entities.
-
-### SpawnService
-Turns planned entries into entities at validated tagged spawn points. Supports equipment, attributes, scale, vehicles/passengers and session tagging.
-
-### ArenaIsolationService
-Event-driven boundary/protection rules: entry/exit, teleport containment, block break/place, explosions, endermen, targeting, projectile crossing, loot/XP, interaction rules.
-
-### EnvironmentService
-Transactional temporary water modifications and restoration. Persist enough recovery information to undo interrupted flooding.
-
-### Reward/ReputationService
-UUID reputation/ranks, wave validation, victory currency, admin configuration.
-
-### Presentation/UI
-Titles/action bar, intuitive registration/class/ready screens or interactions. Player commands are not required. Admin commands remain separate.
-
-### Optional integrations
-Separate compatibility adapters loaded only when the mod is present:
-- Cobblemon: block/allow Pokémon actions according to arena rule.
-- EasyNPC: optional hooks/commands/API bridge if verified and useful.
-No Create dependency.
-
-## Persistence
-Use NeoForge/Minecraft-supported persistent data facilities appropriate to 1.21.1. Do not invent ad-hoc unsafe serialization when native codecs/registries are available.
-
-Persist at least:
-- controller/arena definition;
-- reputation/ranks data as appropriate;
-- inventory recovery records;
-- enough active-session recovery marker to detect an interrupted session;
-- temporary environment restoration data while modifications exist.
-
-## State machine invariants
-- Only registered participants may enter participant states.
-- Inventory snapshot success precedes inventory clearing.
-- Starting roster, average reputation tier, wave count and mode are frozen at countdown start.
-- Session-created entities carry session identity.
-- Cleanup is idempotent: running it twice must not duplicate rewards/items or damage the world.
-- Reward payout is idempotent.
-- Recovery is safe after abrupt server termination.
-
-## Data-driven compatibility
-Use ResourceLocations/registries for Item, EntityType, Attribute, enchantment/data component references supported by the target APIs. A definition may reference another mod without compile-time linkage.
-
-## Networking
-Keep authority server-side. Client packets are requests/UI actions only; server validates class unlocks, readiness, arena membership, admin permissions and configuration changes.
-
-## Performance
-- Do not scan the entire arena every tick.
-- Track session entities directly.
-- Boundary checks should be event-driven where possible; low-frequency sanity checks may repair missed crossings.
-- Water changes should be batched/throttled.
-- Spawn validation should inspect only candidate locations/entity dimensions.

-# Minimal Codex prompts
-
-## First run
-Read `AGENTS.md`, `SPEC.md`, `ARCHITECTURE.md`, and `TODO.md`. Inspect the repository and implement **Phase 0 only**. Do not implement later phases. Compile/test, fix errors, then update `TODO.md` only for work actually completed.
-
-## Subsequent run
-Implement the next unchecked phase in `TODO.md`. Follow `AGENTS.md`; read only the relevant sections of `SPEC.md` and `ARCHITECTURE.md`, then inspect existing code before editing. Do not implement later phases. Compile/test, fix errors, and update `TODO.md` accurately.
-
-## Bug-fix run
-Investigate this bug against `SPEC.md` and `ARCHITECTURE.md`: <BUG>. Reproduce or identify the failing path first. Make the smallest safe fix, add a regression test when practical, compile/test, and do not refactor unrelated code.
-
-## Integration run
-Implement <INTEGRATION> only after inspecting the exact installed dependency/API version. Do not guess API names. Keep the integration optional and verify the mod still starts without that dependency.

-# Functional Specification — PvE Arena
-
-Target: Minecraft Java 1.21.1, NeoForge. Server-first multiplayer PvE arena, initially designed for up to ~4 simultaneous participants.
-
-## 1. Core principles
-- One arena is required for V1, but core code SHOULD avoid an irreversible singleton design.
-- A placed **Arena Controller** is the spatial reference for the arena.
-- Arena geometry is builder-owned. The mod manages combat/session rules, not arena construction.
-- Coordinates for arena points are stored relative to the controller.
-- Player-facing flow MUST be intuitive and MUST NOT require player commands.
-- Admin commands/tools MAY be used for setup and content editing.
-- Vanilla and modded items/entities are referenced by registry IDs. Unknown IDs invalidate only the affected definition.
-
-## 2. Arena Controller and bounds
-The controller stores/configures:
-- asymmetric 3D bounding box (`x-`, `x+`, `y-`, `y+`, `z-`, `z+`);
-- lobby/hall location;
-- participant entry/ready location(s);
-- respawn location;
-- exit location;
-- boss spawn;
-- tagged mob spawn points (`GROUND`, `WATER`, optional future tags);
-- water baseline/max level;
-- optional environment/redstone hooks.
-
-Admin MUST be able to visualize bounds and configured points using temporary client-visible effects/particles. Bounds MUST be adjustable without rebuilding the arena.
-
-Spawn validation MUST reject points that cannot fit the entity's actual dimensions (including scale), are obstructed, lack appropriate support/fluid, or are dangerously close to a participant. The director retries another compatible point.
-
-## 3. Session lifecycle
-Nominal states:
-`IDLE -> REGISTRATION -> CLASS_SELECTION -> READY -> COUNTDOWN -> WAVES -> BOSS -> VICTORY -> CLEANUP -> IDLE`
-
-Exceptional endings:
-`DEFEAT`, `ABORTED`, `SERVER_RECOVERY` -> `CLEANUP`.
-
-Flow:
-1. Player registers.
-2. Original player state is durably snapshotted.
-3. Only after successful persistence, arena-controlled inventory/state is applied.
-4. Player enters hall and chooses an unlocked class.
-5. Player enters ready area and marks Ready.
-6. When all registered participants are ready, registration closes and countdown starts.
-7. Waves run.
-8. Final boss encounter runs.
-9. Victory/defeat/abort cleans all arena entities/environment and restores players.
-
-Late joining after countdown is forbidden.
-
-## 4. Inventory safety
-This is a hard requirement.
-- Persist recovery data BEFORE clearing/changing the player's original inventory.
-- Snapshot at minimum: main inventory, hotbar, armor, offhand; include other player state only if implementation deliberately modifies it.
-- On normal exit/elimination: remove arena kit, restore original snapshot, then mark recovery complete.
-- On disconnect/crash: remove player from active session. If restoration cannot happen while offline, restore automatically on next login.
-- On server restart with an unfinished session: cancel/recover the session. Online participants are moved outside and restored; offline participants are restored on next login.
-- A failed snapshot MUST prevent arena entry and MUST NOT clear inventory.
-- Restoration logic MUST be designed to avoid both loss and duplication.
-
-## 5. Classes
-Classes are JSON-defined and include:
-- ID/display name;
-- required reputation rank;
-- armor slots, offhand and inventory;
-- optional descriptive metadata.
-
-Item definitions MUST support full `ItemStack` data/components so vanilla or modded items can retain enchantments, custom name/lore, dyes, banner/shield patterns, armor trims, attributes and other registered data components.
-
-Admin editing:
-- `addItemFromHand` (or equivalent) copies the full held stack into the class JSON.
-- Captured stack quantity MUST equal held quantity for stackable items.
-- Captured damage/durability MUST be normalized to fully repaired.
-- Capture MUST NOT consume the admin's held item.
-- Armor/offhand slot capture commands SHOULD exist.
-- JSON remains the source of truth; in-game editing updates the JSON and revalidates/reloads the class.
-- `/arena class give <class> [player]` gives a copy of the complete class kit for testing/display (e.g. armor racks), without registering a session.
-
-Class choice locks when the player becomes Ready. Multiple players MAY choose the same class unless later configured otherwise.
-
-On participant death with lives remaining:
-- arena kit does not drop;
-- consumed items are NOT restocked;
-- durability/remaining stack counts are preserved;
-- player respawns in the arena respawn zone with the same remaining kit state.
-
-## 6. Reputation and ranks
-- Reputation is permanent, per-player progression keyed by UUID.
-- Currency is separate and spendable.
-- Ranks are JSON-defined thresholds, e.g. Recruit/Fighter/Veteran/Champion.
-- Classes SHOULD require a rank ID rather than duplicate numeric thresholds.
-- Average reputation/rank of the starting group determines the session's configured wave-count tier. This is frozen at session start and never recalculated after disconnect/elimination.
-- Reputation is earned per validated wave.
-- In clear-to-progress mode, wave N validates when its required mobs are defeated.
-- In timed-pressure mode, wave N validates when wave N+2 is reached; victory validates any remaining pending waves.
-- Eliminated players keep reputation already earned.
-
-## 7. Lives and modes
-Keep "mode" separate from wave power/budget.
-
-Default modes:
-### Clear-to-progress (easy-style)
-- Lives are individual.
-- Next wave begins after all required arena mobs for current wave are defeated.
-- Wave validation occurs on clear.
-
-### Timed-pressure (hard-style)
-- Lives are shared by the team.
-- Each wave starts after a configured timer even if previous-wave enemies remain.
-- Wave N reputation validates when N+2 is reached.
-
-Exact life counts/timers/multipliers are configurable balancing values.
-
-When a player has no applicable life remaining, they are eliminated:
-- removed from session participation;
-- teleported outside;
-- original inventory restored.
-Remaining participants continue. Defeat occurs when no active participants remain (subject to mode rules).
-
-## 8. Wave Director
-Wave difficulty is budget/score-driven, not encoded as `easy/hard` on themes.
-
-Each theme JSON defines:
-- ID/display name;
-- selection weight;
-- mob/variant pool;
-- each entry: cost, weight, optional min/max, compatible spawn tags;
-- optional environmental requirement such as water level.
-
-For each wave:
-1. Determine target score/budget from wave progression, player-count scaling and configurable session scaling.
-2. Select a valid theme.
-3. A theme used recently is excluded for the next 5 waves by default (`themeCooldown`, configurable).
-4. If too few themes exist, gracefully relax cooldown using least-recently-used fallback.
-5. Compose mobs until near target budget while respecting weights/min/max.
-6. Spawn progressively through validated compatible spawn points.
-
-Player-count scaling SHOULD primarily increase mob budget/count. Health scaling MAY increase modestly and MUST be separately configurable; avoid turning normal mobs into excessive HP sponges.
-
-At wave start, participants receive a Title:
-- title: `Vague <N>`
-- subtitle: theme display name.
-Action bar MAY show useful mode-specific status (remaining enemies or next-wave timer).
-
-## 9. Mob variants, equipment, mounts
-Mob definitions MAY include equipment/full item stack components and configurable registered attributes such as max health, attack damage, armor, movement and `minecraft:scale`.
-
-Composite spawns MUST support vehicles/passengers (e.g. spider jockey, mounted skeleton). Treat a composite as one director selection with one total cost. Limit nesting depth.
-
-Third-party registered entity IDs MAY be used without a compile-time dependency. Missing entity/item/attribute IDs invalidate the affected definition with diagnostics, not server startup.
-
-## 10. Bosses
-- Wither MAY be the default boss but is not mandatory.
-- Boss definitions are data-driven and MAY reference vanilla or modded registered entities.
-- Pseudo-bosses MAY apply name, scale, attributes, equipment, boss bar and optional adds/minions.
-- Third-party boss compatibility is best-effort; arena containment and cleanup still apply.
-- Boss rewards scale with completed session/wave tier.
-- Optional boss mods must never become required dependencies.
-
-## 11. Arena isolation and protection
-During an active session, the arena bounding box is a logical sealed boundary.
-- Participants cannot leave except through arena-controlled teleport/exit.
-- Non-participant players cannot enter.
-- Arena mobs cannot leave; outside mobs cannot enter.
-- Projectiles/effects must not cross the boundary in either direction where technically interceptable; unsafe crossing projectiles should be cancelled/removed.
-- Arena mobs SHOULD NOT target non-participants.
-- Endermen cannot move arena blocks and cannot teleport outside.
-- Explosions can retain combat effects but MUST NOT destroy arena blocks.
-- Participants cannot place or break arena blocks.
-- Existing arena interactions remain usable where safe: ladders, slime blocks, doors/trapdoors/buttons, wind charges, etc.
-- Arena mobs SHOULD drop no normal loot/XP unless explicitly configured.
-- All session-spawned entities (mobs, mounts, passengers, minions, relevant projectiles) are tagged/tracked by session and cleaned on end/recovery.
-- Spectator stands may exist immediately outside the bounding box; spectators must not influence combat.
-
-## 12. Water environment
-No dynamic obstacle system in V1. Builders own obstacles.
-
-Themes MAY request temporary arena flooding by 0..N block layers above a configured water baseline.
-- Only safe/replaceable positions may be temporarily filled.
-- Never overwrite permanent arena geometry blindly.
-- Track every modified position needed for exact restoration.
-- Water MAY rise/fall progressively for presentation.
-- Restore on theme transition as designed, session end, abort and recovery.
-- Recovery MUST handle server restart without leaving permanent unintended flooding.
-- `WATER` spawn points become eligible when appropriate.
-
-## 13. Cobblemon and other integrations
-Cobblemon support is OPTIONAL.
-- If absent, arena works normally.
-- If present, arena rules can allow or block Pokémon use/sending/battling during a session.
-- Integration code must be isolated and written only against verified APIs for the installed target version.
-
-EasyNPC is OPTIONAL presentation/integration only. Core registration/readiness/session behavior must work without it.
-Create is NOT a dependency. Builders may use Create/redstone around the arena independently.
-
-## 14. Rewards and forfeit
-- Currency reward is equal per qualifying starting participant; do not create a pot that grows for survivors when teammates are eliminated.
-- Default: currency is awarded on final victory; amount depends on completed wave/session tier and configurable scaling.
-- Reward item/currency can be configured in-game from a held ItemStack and persisted in configuration.
-- Reputation is progression-based as described above.
-- Collective forfeit is available through an in-chat vote among active participants.
-- Default vote: absolute majority; solo = immediate. Duration/config is configurable.
-- Successful forfeit -> ABORTED -> cleanup, exit and inventory restoration; no victory currency.
-
-## 15. Validation philosophy
-Provide useful startup/reload/admin diagnostics for:
-- missing registry IDs;
-- malformed class/theme/boss definitions;
-- impossible min/max/cost values;
-- missing required arena points;
-- invalid bounds/spawn points;
-- incompatible boss size warning.
-
-Invalid content should be disabled locally whenever safe instead of crashing the server.

-# Arena of Shinuwa
+Installation information
+=======
 
-Server-first PvE arena mod. Phase 0 provides only the bootstrap: mod loading,
-server configuration, logging and a test setup. No gameplay is implemented yet.
+This template repository can be directly cloned to get you started with a new
+mod. Simply create a new repository cloned from this one, by following the
+instructions provided by [GitHub](https://docs.github.com/en/repositories/creating-and-managing-repositories/creating-a-repository-from-a-template).
 
-## Development versions
+Once you have your clone, simply open the repository in the IDE of your choice. The usual recommendation for an IDE is either IntelliJ IDEA or Eclipse.
 
-Versions retained from the repository:
+If at any point you are missing libraries in your IDE, or you've run into problems you can
+run `gradlew --refresh-dependencies` to refresh the local cache. `gradlew clean` to reset everything 
+{this does not affect your code} and then start the process again.
 
-| Component | Version |
-| --- | --- |
-| Minecraft | 1.21.1 |
-| NeoForge | 21.1.235 |
-| Java toolchain | 21 |
-| Gradle wrapper | 9.2.1 |
-| NeoGradle userdev | 7.1.38 |
-| NeoForm / official Mojang mappings | 1.21.1-20240808.144430 |
-| Parchment mappings | 1.21.1 / 2024.11.17 |
-| JUnit Jupiter | 5.11.4 |
+Mapping Names:
+============
+By default, the MDK is configured to use the official mapping names from Mojang for methods and fields 
+in the Minecraft codebase. These names are covered by a specific license. All modders should be aware of this
+license. For the latest license text, refer to the mapping file itself, or the reference copy here:
+https://github.com/NeoForged/NeoForm/blob/main/Mojang.md
 
-The local verification environment uses Java 21.0.8. Mojang mapping names are
-subject to [Mojang's mapping license](https://github.com/NeoForged/NeoForm/blob/main/Mojang.md).
-
-## Layout
-
-- `src/main/java/com/shinuwa/arena`: common mod entrypoint and logging.
-- `src/main/java/com/shinuwa/arena/config`: NeoForge server configuration.
-- `src/main/resources/META-INF/neoforge.mods.toml`: mod metadata.
-- `src/test/java/com/shinuwa/arena`: JUnit tests.
-- `.local`: specification, architecture, phased checklist and reference examples.
-
-Mod ID: `arena`. Only Minecraft and NeoForge are required. Cobblemon, EasyNPC,
-Create and boss mods are not dependencies. Further component packages will be
-introduced with their implementation phases in `.local/TODO.md`.
-
-## Build and test
-
-Use JDK 21 and the checked-in wrapper:
-
-```sh
-./gradlew build test
-```
-
-The mod JAR is written to `build/libs/arena-1.0.0.jar`. Tests check configuration
-defaults, invalid-value correction and preservation of an explicit opt-out.
-The existing GitHub Actions build runs the Gradle `build` checks as well.
-
-## Manual bootstrap smoke test
-
-1. Run `./gradlew runServer` with no optional mods installed. On first launch,
-   review Minecraft's EULA and, if you agree, accept it in `run/server/eula.txt`,
-   then run the command again.
-2. Wait for the server's `Done` message. Confirm the log contains
-   `Arena of Shinuwa initialized` and `Arena bootstrap ready on Minecraft 1.21.1`.
-3. Confirm `run/server/world/serverconfig/arena-server.toml` contains
-   `logServerStartup = true`. Stop the server using `stop`.
-4. Set that option to `false` and restart. The initialization log should remain,
-   and the `Arena bootstrap ready` message should be absent. Stop the server.
-5. Run `./gradlew runClient`, then create a single-player world to repeat the
-   startup check on an integrated server. Its config is under that world's
-   `serverconfig` directory. No example blocks, items or creative tab should
-   appear under this mod.
-
-These are manual procedures; passing compilation/unit tests alone does not
-verify a graphical client or a complete server startup.
