A mismatched or missing current-build stamp restores the immutable default
snapshot atomically before the VM loads scenes. The new integration case edits
current on build A, opens on build B, and verifies the factory layout returns.

The matching-build persistence slice is in place: existing layouts are captured
once as defaults, first-run factory scenes are saved and captured before the
creator can edit, and same-build startup continues to load current rows. Default
asset references survive current-layout saves.
One integration test covers the current-layout roundtrip and immutable default.

this split keeps layout state independent in the same SQLite store:
