Root Cause Primary Domain
Objective
Capture and validate the root cause primary domain element within the Causal Separation Chain layer.
UAIF requirement
The incident record should implement the canonical root_cause_primary_domain field using the defined UAIF data type, validation constraints, and conditional rules.
Business impact
Supports defensible separation of initiating cause from observed manifestation and records uncertainty in causal attribution.
Validation approach
Validate root_cause_primary_domain for required in the Core profile, controlled vocabulary membership. Then review semantic consistency against the source incident evidence and the selected conformance profile.
Expected evidence
Retain the source record or analyst input for root_cause_primary_domain, 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/root_cause_primary_domain.
Implementation guidance
Populate root_cause_primary_domain 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 root_cause_primary_domain is populated only when applicable, conditional rules are enforced, provenance is retained and downstream systems do not change its meaning or precision.
