+ * release_inspections' rows on the HDD (pg_default), its indexes staying in the catalog's tablespace (default_tablespace:
+ * nvme on homelab). It's the prober's output, appended to and read a release at a time (the judge, the web's release
+ * page): 40% of the NVMe's growth while probing, 4.6 GB of it, with the probe backlog needing more than the NVMe had left
+ * (LOG.md 2026-10-18 (79)). Homelab moved it by hand (prober, merger and judge stopped); a no-op where it's there
+ * already, or without a default tablespace (tests).
