-// Command rename-rollback reverses migration 0004.
-//
-// Run it only as part of a decision to revert the release that introduced the
-// instance rename. It renames instance_id back to org_id and restores the two
-// collection names. Like the migration, it only renames — it deletes no
-// documents.
