DUAL-WRITE: appends CAPREG to /tmp (the live registry) AND knowledge/status/cap_registry_durable.log -- the Archivist's reboot lesson applied at write time, not snapshot time (/tmp already ate CAPREG 216-220 once). Also flags to the PM log the FIXED core defect found en route: nx_inv_query_term read `count` u32s but pass-2 dedup writes only `write_cursor` entries -> the zero tail surfaced PHANTOM docid 0 (fix: fill from cursor). license_tier: ORIGINAL
