-- [-] **Outfit part library (owner chose the one-time manual download).** The upstream modular pack is
-      a Google Drive folder (<https://drive.google.com/drive/folders/1USAAquX2JJWuA2m6zol0KUkFe3UkZ8zX>);
-      the owner downloads it once, everything after that is scripted. Steps:
-      1. download the pack and drop the archive (or its extracted folder) into
-         `tmp/quaternius-intake/` — that directory is gitignored;
-      2. `python3 tools/quaternius_parts.py inventory --dir tmp/quaternius-intake` — lists every GLB
-         with its meshes, triangles, bones and materials, so the usable parts are picked by
-         measurement instead of by filename;
-      3. `python3 tools/quaternius_parts.py extract --file <glb> --mesh <name> --out parts/<part>.glb`
-         writes one skinned part onto the 62-joint rig (the only accepted part shape);
-      4. `python3 tools/quaternius_parts.py verify --dir assets/models/blender_src/quaternius/parts`
-         records the SHA-256 of what was kept, then copy the accepted sources into
-         `assets/models/blender_src/quaternius/parts/` and add the rows to `CREDITS.md`;
-      5. assign parts per role in `CHARACTERS[...]["parts"]` and rebuild.
-      Nothing lands in `assets/` until step 5, and the pack itself is never committed.
-      Tooling is ready and proven: `inventory`/`extract`/`verify` work, and a scratch part joined
-      onto a base and exported cleanly before the pack arrived. The part contract is in
-      `assets/models/blender_src/quaternius/parts/README.md`. **Waiting on the owner's download.**
-      A `bald` hair variant also needs a skull-covering crown on the `worker` base first.
+- [x] **Outfit part library — intake landed (`Suit` pilot).** The owner downloaded the
+      *Ultimate Modular Men* pack (CC0, 15 families, FBX only) into `tmp/quaternius-intake/`.
+      `tools/quaternius_parts.py make-base` composes a family into a skinned base GLB, undoing five
+      FBX artefacts (per-file armatures, `_end`/`neutral_bone`, node transforms, the shared
+      jacket/trouser fabric, seam degenerates). `Suit.glb` is the first base: `npc_coat` is now a
+      dark formal suit instead of a tinted hoodie. The pitfalls are recorded in
+      `docs/npc-model-sourcing.md` and `MEMORY.md`.
+- [ ] **Remaining outfit families.** The pack also has Adventurer, Beach, Casual_2, Farmer, King,
+      Punk, SpaceSuit, Swat and Weapons (pistol/sword — unused, the game has no weapon system).
+      Pick the roles each one fits, add a `QUATERNIUS_SOURCES` entry per family with its slot map,
+      then rebuild. `Swat` and `SpaceSuit` have **no hair or eye geometry** (helmeted heads), so
+      they need the five-slot question answered first: hair would be an invisible patch under the
+      helmet, or the audit loses a slot.
+- [x] Intake tooling: `inventory` / `extract` / `verify` / `make-base` in
+      `tools/quaternius_parts.py`, all exercised against the real pack.
 - [ ] Bake per-slot albedo/normal/ORM maps and a per-slot atlas; the five slots currently share one
       whole-body UV set, which caps how much the cloth/pants tints can differ.
