No description
Decouples five cross-cutting concerns from engine core so new presets compose without special-casing: - Piece attributes: CORE_PIECE_ATTRS + PresetDef.pieceAttributes; engine.effectivePieceAttrs unions them. HP is now preset-owned. - Spawn pipeline: engine.spawnPiece() + onPieceSpawn hook replaces hand-rolled materialization. Queen-splits seeds HP via the hook, not via direct knowledge of piece-hp. - Hook signatures: all hooks now take single context objects (LifecycleContext, MoveHookContext, CaptureHookContext, DamageHookContext, SelfCheckFilterContext, GameResultHookContext, PieceSpawnContext, BeforeMoveContext, TurnStartContext, DescribeMoveEffectContext). - Piece-type registry: PIECE_TYPE_REGISTRY + core-piece-types.ts replaces hardcoded FIDE switch-tables in engine/check/checkmate/ stalemate/Piece.tsx. Custom piece types plug in without engine edits. - Preset-scoped state: engine.presetState<T>(id) backed by facts on PRESET_STATE_ENTITY. Auto-cleared on deactivate. capture-to-win migrated off GAME_ENTITY.Winner. - Move log: engine.moveLog + MoveRecord + describeMoveEffect hook. - Visual effects: engine.emitEffect/subscribeEffects + VisualEffect + VisualEffectLayer. Explosion, heal, poison renderers. No-op when no subscribers. - Phase hooks: onBeforeMove (with cancel), onTurnStart. Scope-aware dispatch routes onDamage/onBeforeMove/onTurnStart by target/mover color. All 5 production presets migrated. 4 prototype presets (Shield, Cannon, Berserker, PawnStamina) in integration.test.ts exercise every hook. Added test-utils.ts and PRESET-API.md for preset authors. 930 tests passing; bun run check clean. |
