Assessment confidence dimensions

Source corroboration
Single-source

Measures source-group corroboration only; it does not establish factual truth.

Extraction completeness
High

Measures populated source fields after deterministic normalization; it does not measure correctness.

Methodological assignment confidence
Limited

Measures automated assignment support; substantive correctness requires authorized human review.

  • The incident record identifies the location as United States of America.

Reported claims

  • California's vaccine-distribution algorithm used ZIP codes as opposed to census tracts in its decision-making, which critics said undermined equity and access for vulnerable communities who are largely low-income, underserved neighborhoods with low Healthy Places Index scores.

Material unknowns

  • Independent corroboration is not established in the available incident record.
  • The specific AI system is not established by the available record.

Primary governance problem

The incident appears to expose a governance problem involving considered, allocation. Available reporting supports preliminary methodological interpretation, not a finding of fault or non-compliance.

Architecture intelligence

LIGA™ — Liability Governance Architecture

Primary architecture

The reported considered, allocation concern falls within the governed questions represented by LIGA™ — Liability Governance Architecture.

Governance focus: How should considered, allocation be governed in the conditions described by the available incident evidence?

Deeper methodology is withheld because the available evidence does not justify a Parent Standard or Core Module.

Preliminary governance questions

  • How should considered, allocation be governed in the conditions described by the available incident evidence?
  • What operational authority and controls applied to California Department Of Public Health at the relevant time?
  • What evidence would establish how the relevant AI system produced or enabled the reported outcome?
  • What additional independent evidence is required to resolve the material evidence gaps?

Evidence gaps and limitations

  • Only one independent source group is represented; corroboration is not established.
  • AI technology is not specified in the source record.
