Error message

the recorded model DDL should remain available after the probe mismatch

What it means

Test-only assertion: after a compile-time datediff probe mismatch consumed no event, the recorded model DDL write must still be available for later matching. Fires only if semantic-match consumption incorrectly eats recorded events on probe mismatch — a replay-engine regression.

Solutions

1. Fix take_semantic_match so mismatched probes do not consume recorded events
2. Re-run the event replay tests around probe/DDL ordering
3. Treat failure as a replay determinism regression
