Cumulative Bias Index
Objective
Capture and validate the cumulative bias index element within the Acute vs. Chronic Harm layer.
UAIF requirement
The incident record should implement the canonical cumulative_bias_index field using the defined UAIF data type, validation constraints, and conditional rules.
Business impact
Prevents immediate harm and chronic or cumulative harm indicators from being collapsed into one unsupported conclusion.
Validation approach
Validate cumulative_bias_index for numeric bounds and precision. Then review semantic consistency against the source incident evidence and the selected conformance profile.
Expected evidence
Retain the source record or analyst input for cumulative_bias_index, schema-validation output, transformation history, selected profile, schema version and reviewer rationale where judgement is involved.
Mapping and source
UAIF Schema Specification; UAIF Technical Specification; JSON pointer /properties/cumulative_bias_index.
Implementation guidance
Populate cumulative_bias_index from an identified source or documented analyst decision. Enforce the schema constraints at record creation and update, preserve the original value and provenance, and surface validation failures without silently coercing data.
Assessment considerations
Sample records across normal, boundary and invalid conditions. Confirm that cumulative_bias_index is populated only when applicable, conditional rules are enforced, provenance is retained and downstream systems do not change its meaning or precision.
