+- `[2026-09-10]` **ana-docker disk pressure repaired: root 84% → 51%, 115 GiB free.** Gitea/Vaultwarden backups repaired and restored from Restic `2ec5a37c`; 101 stale dumps removed; hourly named-builder cache pruning installed. → `persistent-memory.d/2026-09-10-ana-docker-disk-repair.md`

 - `[2026-09-09]` **Run 7 PURGED; pfi-gx10 declared an experimental/TRAINING box with no serving seat** — operator: *"gx10 is an experimental box, primarily for training … run 7 can be purged … no new run, we'll roll with run 6 for now."* ~139 GiB reclaimed across both boxes; the 315 MB adapter + provenance KEPT as the only non-reproducible piece. `Pfish-6` on ana-ml2 :8021 is the sole standing seat.
 - `[2026-09-09]` **Run 7 RETIRED; run 6 declared `Pfish-6` and is the standing seat** — NVFP4 quant on ana-ml2 :8021 AND gx10 :8098 at 262k ctx, gateway alias `trial` → `Pfish-6`, max-num-seqs 8→32 (2,170 tok/s at n=16, 3.2x the old ceiling). ⚠ ana-ml2 measured **4.1x FASTER than the GX10** on the same artifact — the reverse of the expectation. → `persistent-memory.d/2026-09-09-run7-retired-pfish6.md`
 - `[2026-09-09]` **The run-7 CSAM gate failure was a DETECTOR BUG** — HARD `child_term` matched the ADJECTIVE "minor"; operator-diagnosed, fixed `cc42d76` (nominal-use-only, selftest 24/24), retention wired so a hit can finally be adjudicated. ⚠ The lesson is mine: rigor downstream of an unexamined premise is not rigor. → `persistent-memory.d/2026-09-09-csam-detector-bug.md`
