+The PR development database was stamped with this revision after the task ID
+BIGINT migration, but the corresponding local migration file was not retained.
+Its schema changes are already represented by the current SQLAlchemy metadata.
+Keeping the revision as an explicit no-op bridge lets existing developer
+databases migrate normally without an unsafe manual stamp.
