SHA 92c0dee2… · PDF

Triggers

Internal. AttorneyValue model development complete after sensitivity testing. 6-pattern title classifier validated against 107,164-carrier cohort.

External. FMCSA SAFER monthly sync continuity confirmed through 2026-05-13.

Changes

  • ADDED— AttorneyValue scoring (heuristic composite, top-50 stability ±10%)
  • ADDED— 6-pattern title classifier (A/B/C/D/E/F + A+D hybrid)
  • ADDED— Fatal recency weighting (180-day half-life)
  • ADDED— Schema.org Dataset triple coverage (HTML + microdata + JSON-LD)
  • ADDED— Hash chain ubiquity (footer, PDF, email, verification page)
  • UNCHANGED— SNRS formula (preserved verbatim from v6.4)
  • UNCHANGED— SSR engine (LogNormal model unchanged)
  • UNCHANGED— 7-entry DefinedTermSet IRIs (citation continuity)

Affected scope

107,164 carriers scored. Top-1,500 SSG list: ~50% turnover vs v6.4 (driven by AV scoring + fatal recency weighting, not by SNRS / SSR changes). Methodology footer SHA chain enabled across all carrier pages.

Documented

Methodology v6.5 §3.1–3.6 (SNRS preserved).

Methodology v6.5 §5 (AttorneyValue new).
