+# LDraw parts — credits & license
+
+The `.dat` files under `parts/` (and the primitives they reference) come from
+the **LDraw Parts Library** (the official, community-maintained library of LEGO
+part definitions).
+
+- **Source (upstream):** https://library.ldraw.org/ (`complete.zip` update package)
+- **Provenance (pinned mirror):** the full library is mirrored, audited and frozen
+  in our Gitea at **`electron-rare/ldraw-library-mirror`**
+  (`https://git.saillant.cc/electron-rare/ldraw-library-mirror`). The subset below
+  is the dependency closure of curated parts extracted from that mirror.
+- **License:** **CC BY 4.0** (Creative Commons Attribution 4.0 International).
+  Each `.dat` carries its own `0 !LICENSE Licensed under CC BY 4.0` header.
+- **Attribution:** original part authors are credited in each file's
+  `0 Author:` / `0 !HISTORY` headers. The library founder is James Jessiman.
+
+Only a **curated, kid-friendly subset** is vendored here, not the full library:
+
+| Part   | Description            | Part   | Description            |
+|--------|------------------------|--------|------------------------|
+| 3001   | Brick 2×4              | 3024   | Plate 1×1              |
+| 3003   | Brick 2×2              | 3068b  | Tile 2×2 (groove)      |
+| 3004   | Brick 1×2              | 3069b  | Tile 1×2 (groove)      |

+
+`manifest.json` lists the full **dependency closure** (each part + every
+sub-file / primitive it references, recursively) flattened under `parts/` so the
+web `LDrawLoader` resolves every reference on its first probe (no 404 noise).
+`fileMap` forces `s/` sub-parts to stay relative to `parts/`.
+
+## How to regenerate / extend the set
+
+The closure is built from a local copy of the LDraw library
+(`library.ldraw.org/library/updates/complete.zip`) with a small Python script
+that walks line-type-1 references recursively and copies the closure here,
+emitting `manifest.json`. To add a part, add its `.dat` id to the seed list and
+re-run the builder, then extend `LDRAW_PARTS` / `PART_ORDER` in
+`js/games/ldraw-parts.js` and the `ld:*` entries in `js/games/blocs.logic.js`.
