Example
pidgeon data install fhir-davinci-crd-2.1
pidgeon conform --endpoint https://your-fhir-base/fhir --ig davinci-crd-2.1 --ciThe conform run walks the live endpoint and grades sampled resources against the installed Da Vinci CRD profiles. A failed report exits non-zero; --ci also fails the run on must-support gaps (MUSTSUPPORT-*) and stub-profile fallbacks (CONFORM_STUB_PROFILE).
Validation context
- strict Profile validation grades an instance against this profile's snapshot: cardinality findings carry FHIR-PROFILE-CARDINALITY and terminology binding findings carry FHIR-PROFILE-BINDING.(FHIR-PROFILE-CARDINALITY)
- strict Under pidgeon conform --ci, a sampled resource missing one of this profile's must-support elements fails the run with a MUSTSUPPORT-<element> rule id.
- strict If the fhir-davinci-crd-2.1 package is not installed, validation falls back to an embedded subset stub and the report is flagged CONFORM_STUB_PROFILE; under --ci that warning fails the run.(CONFORM_STUB_PROFILE)
