+- Adversary PASS on HC1 (REVIEW-1e): own custom-html cold-verify showed

+- 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
