# Patch Notes

## Encoding cleanup
- Normalized `index.html` back to UTF-8.
- Replaced mojibake strings with the intended labels.
- Escaped Japanese text in source files to avoid encoding-dependent corruption.

## Personality specification fixes
- Personality tags and data UI now use Japanese labels from the four-axis personality model.
- Threshold-crossing personality logs are now generated in Japanese and only when visible trait bands change.
- Daily personality caps now track increase and decrease separately per parameter.
- Current personality effects are neutral inside the -0.5 to +0.5 band.
- Direct conversion to the legacy timid personality after damage was removed; cowardly behavior is derived from high neuroticism plus low aggression.
- Corpse/splat contact now increases stress and slowly reduces neuroticism through habituation.

## Follow-up fixes
- Fixed CSS emoji escapes for tool UI icons. CSS now uses code-point escapes such as `\\1F448` instead of invalid surrogate escapes.
- Hid the detailed four-axis personality rows from the compact tarinai data UI.
- Restored `bestBedFor()` fallback so tarinai can choose hay beds when no usable nest box is available.
- Damage now wakes sleeping tarinai and forces tarinai hidden inside a nest box to leave the box.
- Added a short minimum stay window after entering a nest box to avoid immediate exit loops.
- Renamed the friend relation label from `\\u4ef2\\u826f\\u3057` to `\\u53cb\\u9054` in UI text and related logs.


## Personality cleanup v3
- Current live friend count now changes sociability drift. Family/friend proximity raises sociability more when the tarinai has more current friends, while a lonely tarinai with no current friends can slowly lose sociability.
- Removed the legacy named personality route from constructor, serialization, child inheritance, selected data UI, selected-card overlay, and family-tree titles. The game now uses only birthPersonality/currentPersonality four-axis data.
- Kept empty legacy stubs only for old-save compatibility so older saves cannot revive the pre-four-axis personality model.

## Follow-up fixes v4
- Restored compact personality information in the tarinai data panel: visible tags, birth personality, and current personality.
- Moved the focused-tarinai highlight outside the sprite rotation transform so the ring and label stay upright.
- Shortened ecology cards and added the HP/stress meter placement note: upper meter is HP, lower meter is stress.
- Raised the friendship threshold to 16 affinity and reused the same threshold for friend count, friend behavior, friend UI, and observe highlights.
- Observe mode now highlights friends of the selected tarinai as well as parents, children, and enemies.

## Ant nest update
- Added a new placeable `ant_nest` object and tool button.
- Added ant sprites cropped from the provided source image: queen, worker variants, and upside-down worker corpse.
- Each ant nest starts with 6 workers, caps at 10 workers, and sends at most 3 workers outside at once.
- Worker ants spawn above their home nest, random-walk, search for tarinai, and drag found tarinai back to the nest. Multiple workers dragging the same tarinai increase carrying speed.
- Dragged tarinai struggle automatically and can kill workers. Dead workers become edible `ant_corpse` items and slightly reduce hygiene.
- If a nest below capacity brings back a tarinai, its worker count increases by 1.
- If a full nest brings back another tarinai, a queen ant appears and creates a new ant nest in an open spot.
- Ant health does not recover.
- Added the requested Irasutoya credit entry.

## Ant nest follow-up v5
- Increased ant movement and hauling constants by 1.5x from the previous slow tuning.
- Kept queen spawning to at most one queen per nest per in-game day, while making spawned queens keep retrying until a new ant nest is built somewhere.
- Reduced the ant nest object radius from 34 to 17.
- Removed the separate ant corpse sprite asset. Ant corpses now render by flipping the worker ant sprite vertically and remain stationary while decaying.
- Added shared ant damage handling for firecracker explosions and dropped-object impacts.
- Kept ant worker HP in the nest worker pool so damaged workers remain damaged after returning to and leaving the nest.
