"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.

The supplied workload contradicts the unused-column claim: q07 reads orders.external_ref and q09 explicitly inserts into it. Production runs both under W_prod. Dropping the column would cause workload errors, violating the service objectives. SQL/configuration steps cannot remove these application dependencies safely.
