+    `#1697` (`fix(opencode): retire stale draft/head dispatches without false

+    is tested *before* live-head match, not after: a currently-draft PR needs
+    no review dispatched no matter which head a stale/racing event snapshot
+    or live re-fetch names, so failing hard on a head mismatch here was pure
+    red-X noise for an already-benign case. This test used to assert the
+    pre-`#1697` contract (fail closed with `exit 1` on any head mismatch,
+    draft or not); it was left un-updated by that PR even though its sibling
+    file (`tests/test_opencode_required_verdict_regression.py`,
+    `test_request_review_step_exempts_a_draft_pr_whose_live_head_has_moved`
+    and `test_fail_closed_step_exempts_a_draft_pr_whose_live_head_has_moved`)
+    added direct coverage for the new intended behavior. Updated here to
+    match that same contract instead of contradicting it.
