D014 independently checks staging conformance:
- PK uniqueness
- person FK integrity
- required event date
- source-value staging length contract
- Standard Concept validity
- Standard Concept domain-to-table alignment
- unmapped concept_id 0 rate
- type concept 0 rate
OMOP concept_id 0 is characterized rather than automatically treated as corruption. Local release policy decides whether its rate is acceptable.
