The session tried to end and the system said no. At the wrap-up boundary the drift check swept the day's changes and found two derived views left stale behind their sources; one of them the deterministic probe had cleared moments earlier, wrongly, because its hash could not see inside the changed folder.

Judgment sat exactly where determinism was blind, and the irreversible step refused to proceed. Both findings were ticketed before the handoff was written; the gate let the session close only once the drift was on the record.

Filed as the first live proof that the barrier holds at the moment of consequence, which is the only moment that counts.
