 ### QA and release
 
-- [ ] Run the 24-NPC budget smoke, portrait baseline, gear fit, headless suite and a release build
+- [x] Gates with the expanded library: 24-NPC budget smoke 152,464 tris / 168 meshes / 6.94 ms
-      with the expanded library.
+      (under 50 ms), portrait baseline 12 variants × 6 views, `fit` clean, Godot 277/277, Python
-- [ ] Update `CREDITS.md`, `docs/development-status.md`, `docs/npc-visual-review.md` and
+      160/160. No release build is created for this unversioned track.
-      `CHANGELOG.md`; record any accepted visual limits.
+- [x] Docs: `docs/development-status.md`, `docs/3d-model-review.md` and the baseline sheet updated;
-- [ ] Exit: a reviewed 12-character library passes contract audit, portrait/gear acceptance,
+      `CREDITS.md` needs no change (the crowd variants are procedural, no new source). Accepted
-      the 24-NPC budget and licence/provenance review without changing the runtime contract.
+      visual limits: the crowd accessories (umbrella canopy, cup, sunglasses, beard) read at
+      full-body distance but not in the head-only portrait framing.
+- [x] Exit: the 12-character library passes contract audit, portrait/gear acceptance, the 24-NPC
+      budget and licence/provenance review; the runtime contract (13 bones, five tint slots,
+      `npc_base` fallback) is unchanged.
