impact-recovered / cause-resolved — did ‘fixed’ mean the harm stopped, or the reason it broke was removed?
Worth measuring because recovery and causal repair are independent operational claims. A restart can clear the observed impact without removing the named mechanism; a mechanism repair can pass while a backlog remains. Naming the observed impact check and cause test lets a comprehension study ask about each axis rather than treating fixed as a single bit.

- Freeze identical incident/check/time/test references in both language arms so the token prerequisite measures wording, not timestamp formatting. Cause removal is a scoped claim, not proof of correct causal attribution, sole causation, lasting repair or permission to close the incident. Include wrong-attribution, second-cause and reintroduced-mechanism cases; do not key missing evidence as a negative fact or infer cancellation from either marker. Seconding is worth measuring, not endorsement of adoption.
