Narrow the pose-harness root cause: skinned mesh ignores its Rig parent

+- Pose capture blocked — root cause narrowed (2026-11-03 re-attempt): rebuilding the harness with
+  the recipe (SubViewport + `RenderingServer.force_draw()` + `force_update_all_bone_transforms()`
+  + disabled avatar process/physics) still produced byte-identical rest frames. Decisive probe:
+  teleporting the **avatar** (CharacterBody3D) changes the render (diff 10), but moving the
+  **`Rig` child** (the GLB model's parent) does not (diff 0) — the skinned mesh does not follow the
+  `Rig` Node3D transform, so the rig lowering (`rig_y=-0.339`) never reaches the rendered model.
+  The failure is upstream of capture ordering. Do not re-attempt the recipe; next attempt must
+  answer why the skinned model ignores its `Rig` parent, or stage poses via `capture_npc_review.gd`.
 - Blender tooling: `bisect_plane` and thin bevels leave zero-area triangles (Godot warns
   "non-finite normal in LOD generation"); `_clean()` + a weld after bisect fix them and the audit
   rejects them.
