 ## Known gaps
 
 - External first-time-player sessions and balance sweeps are not completed.
-- The Quaternius NPC base is wired for one character (`npc_casual`): arm-down rest, five tint
-  slots, unwrapped UVs, 62-joint rig at source proportions, Idle/Walk/Sit pose code, 6,206 tris.
-  The remaining `0.9.9` blocker is the owner face/silhouette decision
-  (`docs/screens/npc-face-gate/`); the full 12-role roster rollout is `0.9.10`. The other eleven
-  characters stay procedural with the MakeHuman head until that decision lands.
+- The Quaternius roster is shipped (`0.9.9`): all twelve characters are baked from the three CC0
+  sources (casual tee, hoodie, work clothes), 4,458–6,424 triangles each, 62-joint rig at source
+  proportions, arm-down rest, five tint slots, unwrapped UVs and baked 256² AO. The procedural
+  library and the MakeHuman head remain the tested fallback.
+- Roster silhouette variety is narrower than the procedural library (three meshes for twelve
+  roles, differentiated by tint and gear) until the modular part library is added.
+- Head gear is authored for the shipped Quaternius head; the procedural fallback therefore wears
+  slightly undersized caps. Cosmetic, fallback-only.
 - Accessibility/localization acceptance, target-hardware profiling, macOS
   signing/notarization and AI/storefront legal approval remain open.
 - Live 3D replay, recorded VO/music, more venues and seasonal content are future
