 `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 textures and materials of the sand theme (the theme of nine of the eleven battlefield scenes, §15).
-- `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.

 digits in that mode. The mark is computed in the sim; the random offset above the model is client-side. The
