# Patch Notes 15.24.33

## 15.24.33

- Version: `15.24.33`.
- Build: `compact-save-v2`.
- Added item-bucket dirty tracking, `ensureItemBuckets()`, `itemById()`, `liveItemsOfType()`, and `addItem()` to keep type buckets and id lookup coherent after runtime item additions.
- Routed common item creation paths through `World.addItem()` for placements, rain water, grass growth/spawn, zunchi burst/spawn, ant corpses/nests, Tarinai death traces, and constructed owned structures.
- Expanded runtime diagnostics with bucket dirty state, item id-map size, and bucket rebuild counters.
- Reworked several hot item lookups to use buckets or id-map helpers where safe.
- Updated regression checks for item-bucket helper availability and direct item push documentation.
- Added final pre-save runtime-polish report and remaining-work split note.
- Did not touch save migration, population/family limits, or family-tree UI.

# Patch Notes 15.24.31

## 15.24.31

- Version: `15.24.31`.
- Build: `social-balance-runtime-polish`.
- Fixed social-action balance regression where conflict could dominate too often after ActionSpec migration.
- Reduced normal conflict pressure, lowered fight/intimidation priority, and raised mate/bond selection weight.
- Added pair-level fight cooldown guards so one pair/individual cannot trigger repeated fight starts in the same burst.
- Shortened intimidation/defeated display timers.
- Preserved fight mochi as a strong forced exception while reducing ordinary proximity-fight probability.
- Added regression checks for social balance constants and fight re-entry guards.
- Did not touch save migration, population/family limits, or family-tree UI.

# Patch Notes 15.24.30

## 15.24.30

- Version: `15.24.30`.
- Build: `action-spec-sunbath-runtime-check`.
- Moved `sunbath` into `createSunbathActionSpec()` and registered it directly in `TARINAI_ACTION_DEFINITIONS`.
- Removed the remaining `configureTarinaiNeedActions()` late-binding bridge.
- Kept the existing sunbath body/timer subsystem intact; player-visible sunbath behavior should remain unchanged.
- Updated regression checks so late action patching is treated as a failure.
- Did not touch save migration, population/family limits, or family-tree UI.

# Patch Notes 15.24.29

## 15.24.29
- Migrated social/fear/combat/mate/birth runtime actions into ActionSpec factories.
- Kept family data, family tree UI, population limits, and save migration untouched.
- Added regression checks for pass 3 ActionSpec migration.
- Build: `action-spec-social-runtime-check`.

# Patch Notes 15.24.28

## 15.24.28

- Added centralized behavior-text composition through `composeTarinaiBehaviorText()` and `patchBehaviorTextFromComposer()`.
- Added `textTarinaiAction()` to the ActionSpec lifecycle helpers.
- Kept existing explicit live behavior text as the default display fallback so player-facing wording does not churn during normal observation.
- Added a player-visible diff check comparing the current build against the initial 15.24.20 ZIP.
- Kept save migration, population/family caps, and family-tree UI out of scope.

# Patch Notes 15.24.25

## 15.24.25

- Added `scripts/regression_check.py` and `docs/REGRESSION_CHECKLIST.md` to freeze the current generated-file, syntax, and ActionSpec lifecycle baseline.
- Expanded `js/tarinai_action_spec.js` with explicit lifecycle helpers: `selectTarinaiActionTarget`, `canStartTarinaiAction`, `startTarinaiAction`, `tickTarinaiAction`, `finishTarinaiAction`, and `failTarinaiAction`.
- Migrated need-action definitions from legacy `condition/run/update` shape toward explicit `selectTarget/canStart/start/tick` ActionSpec fields.
- Routed priority/action eligibility through `canStartTarinaiAction()` while preserving legacy fallback behavior.
- Added finish/fail lifecycle calls for completed or failed action ticks.
- Kept save migration, population caps, family caps, and family-tree UI out of scope.

# Patch Notes 15.24.23

## 15.24.23

- Added coarse-grained spatial invalidation via `markSpatialDirty()` + `ensureSpatial()` for the main update loop.
- Reduced redundant spatial rebuilds around item, ball, ant, and Tarinai update phases while keeping direct `rebuildSpatial()` calls compatible.
- Added per-type item buckets in `updateItemCounts()` and switched ball-ball collision setup to `itemsOfType("ball")`.
- Reworked render layering into a cached dynamic render stack so expensive y-sort work runs on a short interval or count/signature change, not every paint.
- Kept population and family-tree UI behavior unchanged.

# Patch Notes 15.24.22

- Added `activeBehavior` as the authoritative runtime behavior layer above legacy state timers.
- Added `forcedBehaviorQueue` and `forceBehavior()` hook for external forced actions such as love mochi, fight mochi, and drugs.
- Re-routed love mochi, fight mochi, and sleep drug effects through forced need actions.
- Converted eating, panic, fighting, intimidation, and birth ritual display/scheduling to behavior-backed actions.
- Split social need pressure internally into bond/family/mate/conflict/fear parts and used those parts in social action selection.
- Weighted fulfill action selection by its internal reason parts.
- Reduced direct old-style birth starts: proximity now raises mate pressure; ritual starts when mate behavior is active or forced.
- UI action text now prefers `activeBehavior` over stale thoughts or intent strings.

## 15.24.22
- `js/tarinai_action_spec.js` を追加し、行動を `ActionSpec` として登録できる共通層を導入。
- 既存の `condition` / `run` / `update` を維持しつつ、`canStart` / `start` / `tick` / `finish` / `fail` / `text` に段階移行できる互換ラッパーを追加。
- `TARINAI_ACTIONS` を `TARINAI_ACTION_DEFINITIONS` から登録生成する形に変更。既存参照は維持。
- 行動開始・継続処理を `startTarinaiAction()` / `tickTarinaiAction()` 経由へ移行。
- `behavior` に `specId` / `specKind` を保持し、表示・旧API互換と行動仕様の対応を追いやすくした。

## 15.24.21
- 外部強制行動を queued / active / retry / expire の状態機械に拡張。
- 強制行動の source / forcedReasonText を activeBehavior に保持し、旧タイマー同期で失われにくくした。
- 関係欲求の開始判定を social 大分類ではなく bond / family / mate / conflict のサブ欲求に寄せた。
- 食事行動を activeBehavior 内で対象接近から摂食完了まで完結するよう整理。
- 行動選択時に高い未選択欲求がある場合、「眠たいけど、食べている」のように対立理由を表示。

## 15.24.21
- 外部強制行動を強化。薬・餅から `forceBehavior()` 経由で優先割込み、対象再探索、失敗時再試行を行うようにした。
- へこ餅、けんか餅、ねむり薬の強制行動優先度を更新。
- 喧嘩対象が Item 等になった場合の `relationTo is not a function` エラーを防止。
- 睡眠欲求を概日圧 `circadianSleepPressure` 中心に変更。夜は大きく上昇、昼下がりは微増、それ以外は減衰。
- 初期生成時、夜なら睡眠欲求が高めになるよう初期エネルギーと概日圧を調整。
