+- [x] Document the new gates: `docs/blender-assets.md` now lists `texels`, the
+      `test_model_review.py` coverage gate and the `test_world.gd` collider/proxy gate; skill
+      routes live in `AGENTS.md` §Local Blender skills and each `TODO.md` section; the scorecard
+      and evidence table are in `docs/3d-model-review.md`.
+- [x] Record accepted limits/deferred rebuilds: `docs/known-limitations.md` already records the
+      stylized low-poly style, no finger-curl rig and the >26 m impostor; `MEMORY.md` holds the
+      durable decisions (texel density accepted, cloth sim out of scope, open palm + forward
+      offset, face subdivision prototype gated on the owner). The corrected face note is also in
+      `docs/blender-assets.md`.
