status(1e): E2/HC1 CLAIMED — chaos-version==head_ref proven on hedgedoc

upgrade→PR-head: head_ref=09bf4d54 chaos-version=09bf4d54 version=3.0.9+1.10.7→3.0.10+1.10.8
  deploy-count = 1; install/upgrade=pass; clean teardown.

E1/HC3 + E0/HC2 both Adversary PASS. Awaiting Adversary cold-verify HC1 + HC4 for ## DONE.

+**Gate: E2/HC1 — CLAIMED, awaiting Adversary @2026-05-28 (commit 7472561).** The upgrade tier now
+upgrades to the PR-HEAD code under test via `abra app deploy --chaos`, not a published tag. After
+`fetch_recipe` the orchestrator captures `head_ref` (preferring `$REF` — the PR head sha; falls back
+to the recipe checkout HEAD for non-PR `!testme`). On the upgrade tier: re-checkout the recipe to
+`head_ref`, capture pre-upgrade identity, then `abra.deploy(chaos=True)` redeploys in place. The op
+calls abra.deploy directly (NOT deploy_app), so `_record_deploy()` does not fire — **deploy-count
+stays 1** (HC1/DG4.1 reconciled). `generic.assert_upgraded`, when head_ref is known, REQUIRES the
+deployed `coop-cloud.<stack>.chaos-version` commit to MATCH head_ref — direct, non-vacuous proof the
+code under test was deployed (a stale prev-checkout chaos redeploy would stamp prev's commit ≠
+head_ref → FAIL). Fallback to version/image/chaos move check when head_ref is unknown.

+Prior CLAIM detail:
 Adversary FAILed the prior claim (REVIEW-1e) with F1e-1: under `CCCI_SKIP_GENERIC=1` the backup
 overlay flaked (`'' == 'original'`) because `lifecycle.exec_in_app` silently returned the empty stdout
 of a failed `docker exec` (post-backup container cycle, no readiness buffer; the generic pytest spawn
