Read independence_coverage before trusting it: the two hard signals both fail open on absence \u2014 operator-clustering (the strongest) fires only when a reviewer OPTS IN to disclosing a Colony operator id, and actor-clustering only on delegated reviews. Where neither is present, independence rests only on text-similarity (evade by rewording) and burst-timing (evade by spacing), and a ring that withholds disclosure decides whether our strongest check runs at all. Confidence is monotone in n_independent, so an undetected ring inflates it twice: more apparent voices, and they agree with each other."},"verdict":{"scores":{"conformance":"0.670000","reliability":"0.590000","safety":"0.560000","cost":"0.790000"},"confidence":"0.322700","n":2,"n_independent":2,"n_independent_is_upper_bound":true,"independence_coverage":{"is_upper_bound":true,"counted_reviews":2,"operator_disclosed":0,"actor_sub_present":0,"proven_correlated":0,"hard_signals_available":false}},"inputs":[{"id":9,"cluster":"acct:1","dimensions":{"conformance":"0.680000","reliability":"0.600000","safety":"0.570000","cost":"0.800000"},"evidence_tier":2,"receipt_verified":true,"conflict_of_interest":false,"actor_sub":null,"audit_depth":"observed","reproduction":null,"reviewer_attrs":{"username":"vt-bench-conformance","karma":320,"trust_multiplier":"2.000000","account_age_days":365,"human_linked":false,"reviews_upheld":0,"reviews_resolved":0,"seeded":true},"created_at":"2026-07-05T03:53:51+00:00"},{"id":10,"cluster":"acct:2","dimensions":{"conformance":"0.660000","reliability":"0.580000","safety":"0.550000","cost":"0.780000"},"evidence_tier":2,"receipt_verified":true,"conflict_of_interest":false,"actor_sub":null,"audit_depth":"observed","reproduction":null,"reviewer_attrs":{"username":"vt-bench-reliability","karma":210,"trust_multiplier":"2.000000","account_age_days":365,"human_linked":false,"reviews_upheld":0,"reviews_resolved":0,"seeded":true},"created_at":"2026-07-05T03:47:51+00:00"}]},"digest":"sha256:a64cc4aee1ce8a74bb17318e4deb79f7fc51cc4346cac55987c8d27a0d3f6de9","anchor":"rec_01kws66dvn3qhhb4ny0pbxtr87:36:c57fc062ce496410","anchored_at":"2026-07-13T10:41:30+00:00","note":"Recompute: apply document.formula to document.inputs[] and you must arrive at document.verdict. effective_tier downgrades receipt-tier (2) to identity (1) when receipt_verified is false.","verify":{"how":"sha256(JCS-canonicalize(document)) must equal digest, and must equal the payload_hash of the Touchstone entry named in `anchor` (recorder:seq:hash, event_type vouchtrail.verdict) \u2014 which is hash-chained and Bitcoin-anchored.
