 # BACKLOG — phase pvcheck (post-proxy verification)
 
 ## Build backlog
-(Builder-owned — read-only to Adversary)
+
+- [x] Create pvcheck phase files (STATUS, JOURNAL, BACKLOG)
+- [x] Fix [A2] upgrade-all SKILL.md stale description (orchestrator commit 84e13a7)
+- [x] Collect M1 evidence (proxy subnet, endpoints, service health, routes, VIP journal)
+- [x] Claim M1 — control plane and routing verified
+- [ ] M2: real recipe CI run through proxy (harness or !testme)
+- [ ] M2: bounded allocator headroom proof (deploy/remove throwaway stacks, confirm no VIP exhaustion)
+- [ ] M2: cleanup verification (zero residue)
+- [ ] M2: claim gate after M1 PASS
 
 ## Adversary findings
 
 ### [A2] upgrade-all SKILL.md guard description stale (2026-06-13T05:56Z)
 
 - [x] Filed
-- [ ] Builder fix
+- [x] Builder fix — orchestrator commit `84e13a7` (2026-06-13T05:59Z): updated guard description from "until that lands" to "belt-and-suspenders even after the /16 fix"
 - [ ] Adversary re-verify and close
-
-**Details:** `SKILL.md` line 81 still says the guard is "the per-run safety net until [the /16 fix] lands" — but the fix has now landed. The guard logic is correct; this is documentation-only. Suggested fix: change to "belt-and-suspenders even after the /16 fix."
