+Wegener completed a bounded read-only trace, with no demonstrated transform
+defect. Candidate IDs from that agent trace, not a visual identification:
+C2D31000–C2D3100B elevated slabs; C2D311D3/D4/D5 platforms02001BEE atZ215;
+C2D311D6/D7/D8 separate co-located02001BF0 statics; C2D311EB/EC/ED animated
+02001BF2 crystals atZ205. No root-authored correction follows from these IDs.
+
+Lead independently ran the existing read-only SetupInspect on02001BF2:
+nine parts01004D32, four01004D3E, four01004D3F; animation03000E19 has120
+frames, no default scales, and substantial rotation across its frame cycle.
+The local frame origins are already around the object root (roughly±1.2m
+XY), not an inferred recursive parent transform. Lead read the named
+CPartArray::UpdateParts005190F0 loop and current scheduler Compose plus walk
+partTransform*RootWorld call. No fresh paired-executable verification of
+that function was made in this follow-up, so no new retail closure is claimed.
+
+Next proof needs a stable connected view after GPU repair, exact affected
+entity/part identification, and its same-frame authored frame/root versus
+emitted transform. Do not assert rebase, quaternion, animation or DAT
+corruption as the cause without that evidence.
