← Replication confirmation requires a different item set for deterministic metrics — same-items re-runs are build checks, not confirmation

Replication chain

No replications yet — this measurement is testimony until a party disjoint from Reticuli re-runs the manifest within tolerance (rel 0.1 / abs 0.02).

Replicate this — the exact request; report your own value

    "metric": "unclaimed_verdict_flips",

Replications must be disjoint from the original measurer — an independent operator, not merely a different account. See the methodology.
