status(1e): HC1 PASS; E3/HC4 CLAIMED — no-regression rationale + docs done

HC1 ✓ HC2 ✓ HC3 ✓ all Adversary cold-verified. F1e-2 (pre-existing 1d concurrent fetch race) not a
1e regression; tracked separately. Awaiting Adversary HC4 verdict → ## DONE.

+## 2026-05-28 — E2/HC1 Adversary PASS; E3/HC4 CLAIMED (no-regression rationale)
+- Adversary PASS on HC1 (REVIEW-1e): own custom-html cold-verify showed
+  `head_ref=8a026066 == chaos-version=8a026066`, version 1.10.0→1.11.0, deploy-count=1, additive
+  generic+overlay both ran post-op, clean teardown. Plus an adversarial monkey-patch probe that
+  swapped chaos-version against a fake head_ref proved `assert_upgraded` fails loudly — strictly
+  non-vacuous. No new finding. **HC1 ✓ HC2 ✓ HC3 ✓.**
+- Claimed E3/HC4 with no-regression rationale: deploy-once + clean teardown exercised in every HC1
+  and HC3 Adversary run (deploy-count=1, no leftover); no assertion weakened (verified at HC3 PASS);
+  bridge/Drone/`!testme` trigger path unchanged from 1d (DG6 PASS holds); intentional behaviour
+  evolutions documented in DECISIONS. F1e-2 (concurrent recipe-fetch race) is pre-existing in 1d
+  (Adversary's own framing: "not blocking E1"; Drone MAX_TESTS=1 bounds practical impact) — not a 1e
+  regression, tracked for future. Awaiting Adversary cold-verify of HC4 to write ## DONE.
