 ## Current focus
 
-Per operator direction, V5/V6 now use a deliberately seeded stale-test sandbox case rather than waiting
-for a naturally occurring one. The active seeded pair is `custom-html` recipe PR `#3` plus cc-ci test
-PR `#3`. Next: carry that evidence into the remaining V8, V8a, and V9 work.
+A5-5 FIXED: ran full `/recipe-upgrade custom-html` DEFAULT skill against seeded PR#3. Fresh build #81
+confirms same MIME-type failure; accurate explanatory comment posted (#13900, referencing build #81);
+RESULT log written at `/srv/cc-ci/.cc-ci-logs/upgrades/custom-html-upgrade-2026-06-01.md`.
+V6 PASS confirmed by Adversary (cold-verified: cc-ci PR#3, verify-pr.sh GREEN).
+**Active work: V8 `/upgrade-all` + V8a `cc-ci-upgrader` agent lifecycle.**
