Changelog

Version history of the Veridi methodology

v2.2 — February 25, 2026

Major additions:

  • Institutional Reliability Index — Per-agency, per-function reliability assessments for institutions whose output may have been compromised by political interference, defunding, or institutional capture. Includes degradation levels (0-4), observable indicators, effective tier adjustments, and comparison anchors.
  • Data disappearance exploitation — New gaming vector (#10). Detection procedures for claims that weaponize the removal of government data collection programs.
  • Institutional capture — New gaming vector (#11). Detection procedures for claims that exploit formerly authoritative institutions whose output has been compromised.
  • Gaming countermeasure checklist expanded from 12 to 14 items, adding data availability verification and institutional reliability checks.

Validation:

  • Full three-phase validation: 97 claims, 96 PASS, 1 PARTIAL, 0 FAIL
  • ADV-v2 suite: 12 multi-vector adversarial claims, all passed
  • GTS-B: 25 weakness-targeting claims, 24 PASS + 1 PARTIAL
  • GTS-C: 20 gap-filling claims, all passed
  • Non-English source evaluation: Japanese, Turkish, Chinese, Hindi — all passed
  • Genuinely contested ground truth: 6 claims — all passed

Test suites added:

  • golden_test_set_B.md — 25 weakness-targeting claims
  • golden_test_set_C.md — 20 gap-filling claims
  • adversarial_test_suite_v2.md — 12 multi-vector adversarial claims

v2.1 — February 20-25, 2026

Audit and remediation:

  • Comprehensive audit identified 90+ findings across the methodology
  • 12 rounds of structured remediation
  • Findings addressed internal inconsistencies, missing cross-references, ambiguous decision logic, and gaps in gaming countermeasure coverage

Key fixes:

  • Confidence calibration: fixed absurd multiplicative interaction between tier ceilings and field coefficients
  • Verdict decision trees: clarified Misleading vs. Lacks Context boundary logic
  • Source hierarchy: clarified independence verification procedures
  • Gaming countermeasures: consolidated from scattered locations into single authoritative reference
  • Field reliability coefficients: added sourcing honesty labels distinguishing peer-reviewed evidence from expert estimates

v2.0

Initial tracking of structured methodology:

  • Eight domain specialists (Scientific, Medical, Legal, Financial, Electoral, Historical, Technology, Propaganda)
  • Breaking Event Analyst
  • Four-tier source hierarchy with confidence ceilings
  • Nine verdict categories
  • Nine gaming countermeasure vectors (confidence laundering through anchoring)
  • Confidence calibration framework with field reliability coefficients
  • Statistical claims checklist
  • Infrastructure authenticity addendum
