## 13. Local-client art (optional, host-side)
`tools/local-extract/extract.py` (Python: UnityPy + lz4 + Pillow; decodes Arknights' custom **LZ4AK** bundle compression via `aklz4.py`) extracts the art the web download does not include (some of it, most official HUD sprites among it, is on the public mirror too — §22.5) from a locally installed client (CrossOver Windows build or PlayCover iOS build) into `public/assets/local/**` and writes `data/local-assets.json` (`{ groups: { '<subdir>': { name: { path, w, h, kind } } } }`). Everything here is **optional**: clients must render correctly when the file or any entry is missing (fall back to the web assets / procedural art). The emotes and the guide pages below are on the public mirror too (§22.5): fetch-assets downloads them (data/assets.json `ui['emoticon/<dir>/<picId>']`, `ui['guide/<key>']`) and the client shows the local copy first, then that one (`data.js artUrls`); docs/DEPLOY.md §6 lists what still needs the client.
- `map/autochess/TX_autochessi_*` — the real autochess board atlas (`_D` diffuse 2048² with floor tiles, gold-framed high-ground plates, REINFORCEMENTS bench pads, EQUIPMENTS pads, crates, gates; `_N/_M/_E` normal/mask/emission; `common_D` device icons; `BG` backdrop). `map/autochesssand/*` — the sand-theme variant.

- `scene/<stageId>/` and `scene/tex/` — the official scene of a battlefield (§15 "Official battlefield scenes", DESIGN §30.17): `scene.json` (materials, key light, chunk records), `scene.bin` (the meshes in board space), the lightmap pages `lm<i>`, and the materials' albedo textures shared by the scenes. Read from the scene bundles `scenes/activities/<season>/level_<stage>/…`, which the client carries only while the season runs: `extract.py --only scene` takes them from the client or from `--scenes <dir>` / `.cache/official-scenes/*` (`tools/local-extract/fetch_scenes.py` downloads them from the official CDN's in-season version). The 0.2.5 full release zip includes the extracted files when the maintainer extracted them before packaging; a lite zip and a source install may fetch and extract them (`node tools/setup.mjs --scenes`). The repository never stores the bundles or the extracted files.
- `ui/{common,battle,outer}/*` — every sprite of the three official autochess UI bundles (tier chips I–VI, bond disc rings, frames, banners, HUD pieces, badges, backgrounds, mode art).
- `emoticon/<dir>/<picId>.png` — the 36 official battle emotes, 6 themes (`shared/constants.js → EMOTE_THEMES / EMOTES`, `emoteArtPath`; data/emotes.json); also downloaded from the mirror (§22.5).
- `guide/autochess_{home,shop,handbook}_N.png` — the 19 official tutorial pages; stored squashed to 1024² — **display at 16:9** (the mirror copies too, §22.5).

Findings (2026-09-28): 卫戍协议 levels have no scene bundle (`mapId` null; the official hot-update list contains none). The client **builds the board at runtime** from the stage grid using the map theme `arts/maps/map_autochess` (materials `MT_autochess` (albedo `TX_autochessi_D` 2048², normal `_N`, metallic/gloss `_M`, emission `_E`), `MT_autochess_common` (`common_D/_E`: device/gate icons), `MT_autochess_Transparent` (`Transparent_D/N/M/E`), `MT_autochessi_BG` (`TX_autochessi_BG`)), the background meshes `arts/maps/map_autochess/bkg_mesh.ab` (`S_Background_common`, `S_Background_shadow`) and `arts/maps/common/meshes/s_background_common.ab`, device meshes (`s_common_box_01` crate, `s_wind_device` blower, …), plus the standard gate/objective effects. The level's `options.configBlackBoard` carries the official camera framing (`default_pos_x/y`, `default_size`, `enemy_pos_x/y`, …).
Correction (2026-10-11, GitHub #532; PR #533 by @andrew05060414): the first finding above was made off season and is wrong. While a season runs, the official hot-update list carries **one prebuilt scene per battlefield** — `scenes/activities/act1autochess/level_act1autochess_m01…m07` and `scenes/activities/act2autochess/level_act2autochess_m01…m04` (each with `…/lightingdata.ab` and `…_lighting_settings.ab`; Android versions `25-11-21-15-21-44_ee1197`, `26-03-13-06-11-47_14fb99`, `26-04-13-12-31-42_e9b560`); the lists of 2026-09-13 and 2026-10-08 have none, and no 卫戍协议 level data either. The asset index of those versions (`<hash>.idx`: each bundle's dependencies) gives each scene's art: act1 m01–m07 and act2 m02 / m04 depend on `arts/maps/map_autochesssand` (m05 and act2 m04 also on `map_doss_shore`), act2 m01 on `map_lakegarden` + `map_syracuse_metro`, act2 m03 on `map_kxmr` + `map_lm_center`. **No battlefield scene depends on `arts/maps/map_autochess`** (the metal theme the procedural board below draws; in the current client the 矢量突破 scenes `act3break` use it). A scene holds the logic tiles (`(row,col)#tileKey` at anchor-local (col, row, −height), high ground 0.4), the art under `GraphicHolder` (static parts merged into "Combined Mesh (root: scene)" objects, lightmapped: Shadowmask mode, one directional key light), and three sub-graphics `HIDDEN@1…3` (`MapSubGraphicHolder`) that the game switches on: the left normal field, the right normal field and the boss field — the areas of `layout.js AREAS`.
Official battlefield scenes (`board3d/load.js loadScenePack`, `scene.js setScenePack`, `materials.js sceneMaterial`): when `data/local-assets.json` lists `scene/<stageId>`, the 3D board draws that scene instead of the procedural tiles, cliffs and background plane; the devices, gate / objective boxes, field edges and terrain overlays stay as below. The base part is always drawn; a `HIDDEN@n` part is drawn when its centre lies in one of the built areas. Without the scene (not extracted, a load failure, an unknown `version`) the procedural metal board is drawn as before. Approximations: the official shaders are not reproduced — a lit material is albedo × (the lightmap's baked light + key light · N·L · the baked shadow mask), in linear light; normal, metallic and emission maps, the vertex-colour blend (`_HG_VERTEX_COLOR_BLEND_ON`), the sky box, the map effects (`mapeff_*`) and the post-processing profile are not drawn; `Torappu/Scene/StylizedWater` is the board's water shader in the material's colours; crates cast no shadow on a scene. **[ASSUMED]** `SCENE_LIGHT` (`direct` 0.8, `indirect` 0.4, `ambient` 0.2: tuned by eye against the PRTS screenshot of 战场#06, the official post-processing being unknown) and the RGBM reading of the lightmap pages (`scenes.py decode_rgbm`: Unity's linear-space decode, range 5). Owner decision (2026-10-12): these extracted files belong to the 0.2.5 asset pack and may ship in the full release zip; a lite package or a source install may download and extract them on that machine. Missing extractor dependencies keep the metal board. The repository still never stores the official files.
Target: a **real 3D board layer** rendered with three.js (vendored ESM, no CDN) underneath the existing Pixi layer:
- Geometry generated from `data/stages.json` like the official builder: LOW tiles = top quads; HIGH tiles = raised blocks with side walls; forbidden/void, fences, gates (red), objective (blue), hand/temp pads, special terrain; UVs mapped onto the official atlas regions (reuse/extend `public/assets/local/map/autochess/tiles.json`); normal + emission + metallic maps; lighting tuned to match official screenshots (key directional light, ambient/hemisphere, soft contact shadows); official background meshes & texture; device meshes (OBJ exported by `tools/local-extract`) with their textures; animated gate/objective effects.
- One camera model drives both layers: `public/js/render/projection.js` keeps its public API (`worldToScreen`, `screenToWorld`/tile picking, presets, transitions) but derives it from a three.js `PerspectiveCamera` initialised from the official configBlackBoard framing, so Spine units, FX, drag/drop and hit-testing stay aligned with the 3D board.
