Fetch all frozen source URLs 2. Interpret the content against the frozen policy's trigger rules 3. Return a bounded verdict with per-source states 4. Agree exactly on the verdict and on every per-source state 5. Record fetch provenance (HTTP status + content digest) for auditability Verdicts: CONFIRMED — evidence satisfies the policy trigger NOT_CONFIRMED — evidence materially fails to establish the trigger WEAK_EVIDENCE — sources too thin, unavailable, or incomplete CONFLICTING — approved sources materially disagree DISPROPORTIONATE — trigger exists but the requested action is too broad Only CONFIRMED emits a finalized AuthorityGate.issue_token(...)
