 replays. #17490 and #17572 remain unresolved gates, not inferred green from that
 negative result. The next untouched duty remains late stale-head projection repair.

+fixture; all 211 GitHub workflow tests pass after the change. Fresh remote gates
+for the fixture-only commit remain required. The next slice may build on this
+commit while those independent gates run; no stack merge is authorized.

+The second complete local run finished with 1,581 passes and one failure in
+541.48 seconds. The remaining assertion checked no deadline immediately after
+`ready`, which awaits the first pass, not a later coalesced wake. Fixture teardown

+fixture-only commit requires its own fresh remote checks; the two local full
+runs are not reported as passes.
