{"generated_at":"2026-10-10","disclaimer":"Identity/fraud scores are computed from FMCSA public data using FMCSA's own published chameleon-carrier methodology (Report to Congress, 'Implementation of Methodology to Identify Chameleon Carriers'). SSN and EIN match terms are never present in public data; D&B is nominally available but real post-normalization coverage is only 4.14% (91% of source values are a '0' sentinel), and officer data (needed for the name x officer term) is missing for a further ~15% of carriers — so the obtainable match_score ceiling is per-carrier, not a fixed number: 2.5 of 8.5 for most carriers, only up to 4.5 where D&B is genuinely present. See score_provenance (paid tier) or match_score_practical_ceiling (free screen) for the real figure on a given response. A flagged result means this carrier shares contact identifiers with others under FMCSA's own published chameleon-carrier threshold. In hand-inspected review of 50 flagged clusters, 60% were genuine reincarnation or duplicate-registration candidates, 34% were legitimate affiliated fleets under common ownership, and 6% were normalization artifacts. Recall is not measurable against available public labels. This is a corroboration signal with a known false-positive rate, not a fraud determination. match_score >= 1.5 and cluster_size > 1 (or flagged) are NOT the same condition — clustering requires 2+ independent identifier-type families to agree, so materially more carriers clear the score threshold (11.68% population-wide) than are ever flagged (4.94%). A single shared phone or address still counts toward match_score and still appears in carrier_identity_edge, but does not by itself put two carriers in the same cluster. carrier_identity_cluster refreshes on its own slower, independent cadence and can be materially staler than carrier_profile in the same response — every identity response carries its own identity_data_lag_days rather than assuming parity. A carrier absent from identity_cluster_served reports match_score == 0.0 in the API even when the full warehouse's carrier_identity_cluster.match_score is nonzero, for any carrier whose only evidence is a single sub-threshold ARCHI term family (never enough on its own to cluster or flag, per the 2-family clustering rule). This is a deliberate simplification, not a bug — see Identity-Serving-And-Signals-2026-09-06.md's Gap 2 resolution.
