Appeal passage rate

The share of challenges resolved in favor of the person who made them, whether through the operator's appeal procedure or another route. The name keeps the older word; the measure is upheld challenges. A low rate can mean challenges are not being heard. A high rate means many decisions were wrong, which is evidence against the rule that produced them, and the count goes to that rule's owner. Either way, it is an early sign of whether challenges can change outcomes in practice.

Targets & breach behavior. Measurement window: weekly rolling median; monthly review. Target / floor / ceiling: target 10–20% by harm class, floor 5%, ceiling 30% (investigate systemic error). Owner: traceable ownership (required). Breach action: trigger decision-rule audits, staffing surges, or halt automation in the affected class. Public surface: published challenge outcomes with receipt, time transparency, and decision artifacts.
