 Gear total: 5,002 tris across 18 pieces (all far below the 1,500-per-piece cap).
 
+`blender_assets.py fit` readings (2026-11-03): `shoulder_bag` is clear on both `npc_coat` and
+`npc_dress` (the only back-gear clearance the fit test asserts); `sunglasses` sits inside the
+head band at 0.64× head width. Three caveats worth recording, none of which changes a verdict:
+`backpack` (npc_casual) and `scba_tank` (npc_firefighter) report `CLIP` because back gear is
+measured against the **hip/skirt** radius, which is wider than the upper back where the bags
+actually sit; `cap` and `firefighter_helmet` report `band=OUTSIDE` because they sit on the crown
+above the 1.55–1.81 face/head band (expected); and the `lanyard` clip is corrected at runtime by
+`GEAR_OFFSETS` (+4 cm forward). `beanie` is unused and remains a retire/reassign candidate.
