   enrolled recipe (only custom-html enrolled today — resolve during M2: enroll/seed a 2nd, or use the
   registry mechanism on another recipe). Need ≥2 published tags on the step-back recipe for an older
   target to exist — verify custom-html tag count before run.

+## 2026-06-17T04:40Z — M2 real-CI evidence captured (custom-html + discourse)
+
+Two-run authentic nightly simulation on cc-ci (/root/samever-deploy @ cc-ci main, samever code):
+- **Run A** (cold-on-latest, no canonical): upgrade base kind=skip (head==main tip); green 5 tiers;
+  WC5 promote → canonical custom-html = 1.13.0+1.31.1 (the "first nightly").
+- **Run B** = THE HEADLINE (2nd consecutive nightly, canonical==latest==head):
+  `upgrade base: kind=version version=1.11.0+1.29.0 (step-back: last-green canonical (1.13.0+1.31.1)
+  == head version 1.13.0+1.31.1; newest older published base)`. Upgrade tier deployed base 1.11.0+1.29.0
+  then chaos-upgraded to head: `version=1.11.0+1.29.0→1.13.0+1.31.1` (label MOVED, base<head, REAL
+  delta — not a no-op, not a skip). All 5 tiers green. Proves F1d-2: the older base actually deployed
+  the pinned 1.11.0 then upgraded to 1.13.0.
+- **Run C** (version-bump UNAFFECTED, enrolled): re-seeded canonical→OLDER 1.11.0+1.29.0, cold-on-latest
+  head 1.13.0 → `kind=version version=1.11.0+1.29.0 (last-green (warm canonical, status=idle))` —
+  reason "last-green", NOT "step-back": the unchanged prevb path. Upgrade 1.11.0→1.13.0 green. The
+  step-back never engages when canonical≠head.
+- **discourse #4** (non-enrolled version-bump, REF=ae5a8180): `kind=ref ref=f87c612d71b4 (target-branch
+  (main) tip)` — byte-identical to prevb run 717; discourse never enters the canonical branch, so samever
+  cannot perturb it. (Full install,upgrade migration running to green for completeness.)
