Get a calibration certificate
Returns the signed judge certificate for a criterion — what was proven (confusion matrix, TPR/TNR/kappa with intervals, trust verdict), on which population, what voids it, and what enforcement refused involving it — for audits, evidence bundles, or proving a judge’s calibration to a third party.
Free (no judging). 404 if the criterion is not in the workspace. Response is Cache-Control: no-store. Hand the WHOLE JSON object to POST /v1/verify to check the signature later. An uncalibrated judge still returns a certificate that honestly says nothing is measured (calibration.measured=false, trust.trust=‘unmeasured’). enforcement counts refusal-ledger rows from the last 90 days whose subject is this criterion or whose reason names it.

Response
A JSON document whose keys are camelCase (NOT snake_case — it is emitted verbatim so its signature can be re-derived): signature: {alg:'HS256', key_id, value} | null (with unsigned: true when no signing secret is configured), criterionId, name, question (the judge prompt), unit ('request'|'trace'), judgeModel, issuedAt, calibration: {measured, matrix: {tp,fp,tn,fn}|null, metrics: {n, tpr, tprCi, tnr, tnrCi, kappa}|null, labels, holdoutActive (labels >= 80), alignedAt, goldenSet: {id, name, size, membershipHash, frozenAt, humanKappa, humanAgreement, humanKappaN, raterCount}|null}, trust: {trust: 'trustworthy'|'misaligned'|'under-measured'|'borderline'|'unmeasured', failGradesNeeded, passGradesNeeded, tprCi, tnrCi} (or just {trust:'unmeasured'}), population: {tag, segment, unit, statement}, validity: {driftStatus: 'ok'|'flagged', driftReason, driftCheckedAt, voidedBy: string[]}, enforcement: {windowDays: 90, refusalsInvolvingJudge, lastReason}.
The response is of type object.
