   gear library. The procedural library + MakeHuman head stay in the tree as the tested fallback
   (`build --source procedural`), not in the shipped roster. Silhouette variety is the known
   regression — three meshes for twelve roles — and the modular part library is the `0.9.10` fix.
+- **FBX modular parts need five fixes before they are a base (2026-11-06):** (1) every FBX file
+  carries its own armature — keep one and repoint the meshes; (2) FBX adds `_end` leaf bones and a
+  `neutral_bone` root, and **Godot refuses the GLB entirely** (`resource_format_binary` / missing
+  `.scn`) until they are stripped to the 62 joints; (3) bake object transforms before export or the
+  glTF node transforms change the rest pose and the head renders several times too large;
+  (4) the pack reuses one fabric material for jacket and trousers — copy it per leg mesh
+  (`*_legs`) so the slot map can send it to `pants`; (5) imported parts share seams, so dissolve
+  and drop zero-area triangles or the audit fails.
+- **`tmp/` needs a `.gdignore`.** Godot scans the project tree, so a downloaded asset pack under
+  `tmp/quaternius-intake/` gets imported (it flooded the import log and broke `--import` for the
+  rest of the project). An empty `tmp/.gdignore` stops it; capture output there is unaffected.
 - **Modular part intake is a one-time manual download (2026-11-06, owner):** the upstream pack is a
   Google Drive folder, so the owner downloads it once into the gitignored
   `tmp/quaternius-intake/` and `tools/quaternius_parts.py` does the rest
