Define the decision surface
Search ranking, content recommendation and generative answers affect people differently. Oversight should name the decision, the affected audience and the plausible harm.
Require inspectable evidence
Aggregate metrics are not enough. Auditors need documented data sources, change logs, evaluation methods and a way to reproduce material findings.
Build an appeal path
People affected by automated decisions need understandable notice and a route to correction. Governance is incomplete when observation has no remedy.
