DocumentReference.subject must be a literal reference (min=1 on .reference per the DocumentReferenceOrigenAR profile), not an identifier token: the Bus rejects subject.identifier. Go back to using the Patient entry's fullUrl as the reference in both ITI-65 and ITI-67 (ITI-65 was never committed with the identifier-based version, so only ITI-67 needed the revert here), dropping the now-unused extractNationalIdentifier helper.

* ITI-67: Find Document References (MHD)
|
|
*
|
|
* GET /fhir/DocumentReference?subject=:localId
|
|
* GET /fhir/DocumentReference?patient.identifier=:localId
|
|
* GET /fhir/DocumentReference?subject=:localId&type=:type
|
|
*
|
|
* Flow:
|
|
* 1. Fetch the Patient from the Bus by local ID to obtain the national identifier.
|
|
* 2. Search DocumentReferences in the Bus by that national identifier
|
|
* (opcionalmente filtrando por tipo de documento).
|
|
* 3. Return the resulting Bundle.
|
|
*
|
|
* Required query parameter (one of):
|
|
* subject — local Patient ID in the Bus.
|
|
* patient.identifier — same semantics, alternate FHIR parameter name.
|
|
*
|
|
* Optional query parameter:
|
|
* type — token FHIR de DocumentReference.type (`system|code`, `|code` o `code`),
|
|
* ej: `http://loinc.org|60591-5` (IPS), `http://loinc.org|56445-0` (MeOW),
|
|
* `http://loinc.org|57133-1` (IT). Se pasa tal cual al Bus, sin traducir
|
|
* alias propios, para no apartarse de la semántica estándar de búsqueda
|
|
* por token de FHIR. Si se omite, devuelve documentos de cualquier tipo.
