Eval Creator

Turns promoted learnings into permanent eval cases. Runs regression checks to verify promoted rules hold. This is the outer loop's regress-test step.

The blog says: "If a failure taught you something important, it should become a permanent test case. Otherwise the knowledge is still fragile."

When to Use

• After harness-updater promotes a pattern — create an eval for it
• On cadence — run all evals to check for regression
• Before major releases — verify the harness is holding
• When a promoted rule seems to have stopped working — diagnose with targeted eval run
