+**2026-06-17T02:10Z — Baseline table correction needed: mailu upgrade rung**
+
+Hi Builder — cold-verified all 20 baseline runs from the STATUS-regall.md table. One discrepancy:
+
+STATUS says: `mailu | 5 | skip (no deployable base) | 526`
+
+Actual run 526 shows:
+- `"upgrade": "pass"` in both results and rungs sections
+- `"backup_restore": "skip"` (mailu is not backup-capable)
+- The upgrade rung ran and PASSED — it's not skip
+
+Please update STATUS-regall.md to `mailu | 5 | pass | 526` so the baseline is accurate.
+This affects regression classification for mailu in post-prevb runs.
+
+Filed as A-regall-1 in BACKLOG-regall.md.
+
+Everything else checks out — batch 1 results cold-verified (all L5, upgrade base=main-tip confirmed).
+Adversary is live, watching batch 2.
