+### Intake adaptation (`adapt`)
+
+`adapt` is the mechanical first half of an external-mesh intake (MakeHuman,
+MPFB, downloaded GLB): import, apply transforms, ground the feet, weld seam
+splits, decimate to the character budget, and export a GLB. It does **not** map
+the five tint slots or rebuild the 13-bone `npc_base` armature — those stay a
+manual `retopology`/`rigging` step with a recorded second-rig contract if the
+source rig cannot be retargeted:
+
+```bash
+flatpak run org.blender.Blender --background \
+  --python "$PWD/tools/blender_assets.py" -- adapt \
+  --file "$PWD/tmp/npc-research/makehuman_base.glb" \
+  --out "$PWD/tmp/npc-research/makehuman_adapted.glb" \
+  --target-tris 8000
+# prints: adapted makehuman_adapted.glb: 36972 -> 8000 tris (bones=N, meshes=1)
+```
+
+Run `inspect` on the adapted GLB before and after, and keep the procedural
+generator as the fallback until a MakeHuman variant passes `audit`/`fit` and the
+24-NPC budget.
 - Numbers are Blender-side measurements. Triangles match `audit` on project assets; the seam-split
   vertex count can differ by ±1 because the importer rounds normals. `audit` stays the single final
   gate: it is stdlib-only, runs in CI, and matches what the engine imports.

The Web/HQ archives contain `CREDITS.md`, `PRIVACY.md`, `docs/accessibility.md` and `docs/known-limitations.md`; SHA-256 checksums were generated, the Linux and HQ binaries launched headless, and the Web index/wasm/pck/docs served with HTTP 200. The candidate is not published: external playtest, AI-provider/legal approval, macOS signing and the Windows/macOS target matrix remain open blockers.
 - Save migration and reliability (0.10.0 work): committed 0.8-era settings/campaign/history fixtures and a 0.9.0 checkpoint. The loader default-fills old settings, keeps campaign progress and validates checkpoints for all three venues with an open incident, NPC rows, door, flashlight and body-camera state. Corrupt and partial files fall back to defaults; a blocked atomic replace leaves the prior valid file intact. `_load_json` uses the non-logging JSON parser; save locations and rollback are documented in `getting-started.md`.
