Version history

Documented versions

First publicly archived methodology version. Earlier internal revisions exist but are not cryptographically anchored or publicly published. Future revisions will appear in this catalog with hash and erratum trail.

v6.5.h · 2026-05-25

SHA 302bbf71…

Triggers

Internal. Public-surface legal hardening: settlement-value and attorney-engagement-value outputs removed to eliminate unauthorized-practice-of-law exposure; statistical framework rebased on cited primary literature.

Changes

  • RESTRUCTURED— SSR (statistical settlement-value range) removed from all public surfaces; DB columns retained dormant
  • RESTRUCTURED— P90 settlement percentile removed (SSR-dependent + UPL class)
  • RESTRUCTURED— Attorney Value (AV) formula + M_verdict multiplier removed; §8 reframed as Evidence Density Score
  • REFINED— EDS reformulated as a categorical band (HIGH / MODERATE / LIMITED); no numeric score surfaced
  • CORRECTED— Hilburg reference excised; ARCH framework cites Engle (1982) alone
  • REFINED— B-method renamed to multilevel partial-pooling (Gelman & Hill 2007)

Documented

Methodology v6.5.h §3 (jurisdiction tier table), §8 (EDS categorical bands).

Verification: /v/6.5.302bb

v6.5.g · 2026-05-14

Prior version. PDF SHA archived with the operator.

Triggers

Internal. Evidence Density Score (EDS) 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— Evidence Density Score (EDS) — 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— DefinedTermSet IRIs (citation continuity)

Affected scope

107,164 carriers scored. Top-1,500 SSG list: ~50% turnover vs v6.4 (driven by EDS scoring + fatal recency weighting). Methodology footer SHA chain enabled across all carrier pages.

Documented

Methodology v6.5 §3.1–3.6.

Methodology v6.5 §5 (Evidence Density Score — EDS — new).
