A Criterion Run is the result of running a single Criterion against a Task Run. The verification engine creates one Criterion Run per criterion when a task run completes. Criterion Runs replace the legacy Eval Runs resource.

SDK Example

// List criterion runs for a task run
const runs = await verial.criterionRuns.list({ taskRunId: "tr_abc123" });

for (const run of runs.data) {
  console.log(`${run.criterionId}: ${run.passed ? "PASS" : "FAIL"} (${run.score})`);
  if (!run.passed) console.log(run.details);
}

// Fetch one criterion run with full evidence
const detail = await verial.criterionRuns.get({ id: "crun_01H..." });
