F1e-1 (Adversary): exec_in_app silently returned '' on a failed docker exec, flipping a healthy
recipe RED under opt-out (post-backup container cycle, no readiness buffer). Now polls (re-resolve
container + re-exec) until rc==0 or 90s, then RAISES — never masks an exec failure as empty data.
No assertion weakened. Verified: opt-out install,backup,restore on custom-html now PASS.
HC1: head_ref = ref or recipe_head_commit (prefer explicit PR head sha $REF — robust, no git race;
production !testme always sets REF). assert_upgraded, when head_ref known, REQUIRES the deployed
chaos-version commit to MATCH head_ref (direct + non-vacuous proof the PR-head code was deployed; a
stale prev-checkout chaos redeploy fails). Falls back to version/image/chaos move check otherwise.
