  "_comment": "Database Change is a real trigger now - the database reports the change and the webserver starts the workflow - so it can only sit at the start of a flow, and the engine skips a trigger node found anywhere else. That is what this fixture covers: a run started by hand, which has no event to work from and falls back to asking what changed since last time. The event path itself needs a live subscription and a running webserver, so it is not reachable from here; it was verified by hand against insert, update and delete.",
