when: clinicalStatus in (active, recurrence, relapse, absent) AND verificationStatus not in (entered-in-error, refuted) AND onset or recordedDate resolvable
One FHIR Condition maps to one condition_occurrence row. Status filtering drops entered-in-error, refuted, and inactive/resolved conditions. Onset is resolved via a priority chain (onsetDateTime > onsetPeriod.start > recordedDate); conditions with no resolvable start date are skipped. Category drives type_concept_id (problem-list-item vs encounter-diagnosis). Domain routing is not implemented -- all conditions go to condition_occurrence regardless of OMOP vocabulary domain_id.
