The useLiveTransforms + sceneRegistry.position.set approach used by
MoveColumnTool is broken — column ALSO disappears during move, per
user observation. The mesh doesn't visibly follow the cursor.
Items work because their move tool directly updates the scene store's
node.position on every grid:move tick (with history paused), and the
renderer reads node.position. Matching that pattern here.
MoveRegistryNodeTool now:
- Snapshots the original position at mount (for cancel / commit
revert path).
- Pauses scene history so per-tick updateNode calls don't fill undo.
- On grid:move: `useScene.updateNode(id, { position })`. The kind's
registered renderer reads node.position and re-renders, so the
actual mesh visibly follows the cursor.
- On commit: revert to original while still paused → resume → final
update (single tracked action) → re-pause. Undo replays one step,
not the per-tick spam.
- On cancel / unmount-without-commit: restore original position with
history still paused (won't enter undo), then resume.
The cursor sphere stays as the aim indicator alongside the moving
mesh. No translucent ghost — the actual mesh IS the preview now.
