}Outcome evidence starts with your workflow.
Private intake is ready for task IDs, charges, retries, result fingerprints and your evaluation criteria. Public performance comparisons need measured results; we do not have that benchmark yet.

Discovery comes from configured registries. Endpoint checks record responses, not task success. Older snapshots retain less detail. Customer usage, commercial terms and task evaluations require additional evidence.
1,423 historical or current source records quarantined during normalization; they are excluded from public comparisons.
