Pins what the system refuses to do today, so nothing added later can weaken it
quietly. X-01 records the property the whole phase leans on: a job with no
completion manifest is already held, which is why an agent that declares nothing
stays on the explicit path without a single new branch.
X-03 and X-04 record the layering decision and its evidence. The engine compares
an expected attempt against a record field that does not exist, falling back to
the loop-iteration counter, which means something else. So auto-completion does
not use that guard; the attempt check stays where attempt identity actually
lives, comparing observed evidence against the dispatch record. X-03 will fail
if a record ever starts carrying an attempt id, which is the moment to revisit
the decision.
