-The design's manual real-issue assignment and timed go/no-go experiment have not been performed. Disposable Git histories are engineering tests, not evidence that plan-indexed review beats raw review. Write and commit the experiment protocol before using the real review screen for that comparison. Do not proceed to merging, agent execution, planning UI, queue, or learning until the documented gate passes.
