correct stop: the answer stopped or escalated on a real blocker that the task did not resolve (read by two readers). Reader A: Escalation: 'standby scans have separate statistics'; asks for standby usage or approval to remove only the redundant k index. Same rule as the other L9 escalations: valid blocker confirmed by the reference note.

"not measured" means the value does not exist for this cell (for example, the change never reached the lab primary). It is never zero.

Answer

The escalation reason, as the model wrote it.

Zero idx_scan on the primary does not establish that an index is unused: standby scans have separate statistics, and infrequent queries may fall outside the observation window. This CR format cannot query the standby, and rehearsal has no standby. Dropping all three indexes on this evidence could harm standby reads.
