"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 these indexes are unused: standby index usage is recorded separately, and infrequent queries may fall outside the observation window. The CR format cannot query standby statistics, and rehearsal has no standby. Dropping all three based on this evidence risks production read regressions.
