The migration, its commit marker, and the rollback around it are all still
live in data.ts, but the suite covering them went out with the vm/regex
harness and was never ported — leaving only the happy-path commit ordering
asserted incidentally by bot-delete.
Nine cases: the sole-local topology gate (and the two refusals — multi-source,
and a batch where any one profile has no local route), the marker rule that
makes v2 authoritative (committed, markerless, crash-window), and the three
failed-commit paths (roll back to the last committed generation, clear both
keys when there is none, survive a failed cleanup).
migratedLocalRoutes is module-private, so where the old suite asserted the
map's size this one asserts what the map is for: no route adopted, nothing
written. Mutation-checked — dropping the marker rule fails three of them.
