 ## Known gaps
 
 - External first-time-player sessions and balance sweeps are not completed.
-- The Quaternius NPC base migration is planned, not shipped: the arm-down skin export and the
-  rest-relative pose composition are the open blockers (`0.9.9`), and the roster rollout is
-  `0.9.10`. The current 12-character procedural library and the MakeHuman head remain the
-  tested fallbacks until the face/silhouette gate is approved.
+- 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.
 - 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
