claim(dstamp): M2 — discourse full lifecycle GREEN at true level (LEVEL 5) via drone !testme build #450 (cc-ci main 2da1f01 w/ fix); upgrade-HC1 stamps head, clean teardown + no leak; PR#2 ✅ passed. DEFERRED closed. Blast-radius: only discourse affected. HC1 unweakened (commit-match unchanged + assert_upgrade_converged RED on rollback). Verification recipe in STATUS-dstamp

 - [x] 06-05→06-10 change = rcust-phase heavier resident host load → start-first new task reliably OOMs → rollback every run (solo 06-05 run 184 didn't; my repro2 didn't either).
 - [x] Blast-radius: only discourse affected (keycloak/n8n have the policy but upgrade PASS L4 across runs; drone/traefik infra). General harness guard covers all.
-- [ ] Restore discourse to its true level in real CI via the drone `!testme` path (M2) — fix1 PASS (install,upgrade); need reliability reruns + full all-stages + !testme.
-- [ ] Prove HC1 still has teeth (a deliberately wrong stamp still FAILs).

+- [x] Restore discourse to its true level in real CI via the drone `!testme` path (M2): build #450 = LEVEL 5, all tiers PASS (install/upgrade/backup/restore/custom), clean teardown, no leak; PR#2 ✅ passed. fix1+fix2+450 = 3 consecutive green with the fix.
+- [~] HC1 teeth: code unchanged (generic.py:174-175) + assert_upgrade_converged RED on rollback (repro1/4). Live negative test = Adversary's M2 verification.
+- [x] Closed the DEFERRED.md dstamp re-entry with pointers (✅ RESOLVED).
