Ship the current work. If the branch has an open PR (e.g. from a manual /engineer), merge it once CI is green; otherwise run the validation pipeline plus the tests relevant to the changed files, then commit and push. Use only when the user explicitly invokes /shipit. Never auto-ship.
Audit any eval, metric, experiment, or benchmark for leakage — does external ground-truth enter independently, or are the model, scorer, and designer just confirming a result no outside truth ever produced? Use before trusting any 'how we'll know it worked' — an A/B, a holdout, a score, a validation — and whenever a result feels too clean or self-confirming. Walks an 8-pattern leakage taxonomy and returns only the patterns that fire, each with an independence fix. Read-only.
