+ * release_inspections in the catalog's tablespace (default_tablespace: nvme
+ * on homelab), not CHUNK_TABLESPACE: the prober writes it every flush and
+ * the merger looks stems up in it (release_inspections_inner_stem_idx), so it
+ * isn't only read per release any more (migration 1700). Its flushes took
+ * 35–83 s a minute with the table on the HDD (LOG.md 2026-10-13 (43)).
+ * Homelab was moved by hand first; here a no-op when it's there already, or
+ * without a default tablespace (tests).
