• parent: WBV2-P2-001

Evidence

• Desktop and WASM preserve stable parent/child object IDs, local transforms, world matrices, and source/target collection membership.
• setObjectTransform commits parent translation and propagates child world translation to [2, 2, 0].
• Parent-cycle and invalid linked/locked target edits reject before commit without changing revision.
• Collection move and unparent-with-keep-world commit through authoritative Main; undo and redo are exact.
• Desktop and WASM save/reopen preserve nodes and collections; malformed input is rejected without Main mutation.

Production fixes

• Failed command history restoration no longer advances session revision; undo/redo still advance it.
• Unparent keep-world uses authoritative raw parent/local matrices and decomposes the captured world matrix.
