Pull request overview
This PR implements a comprehensive CMS-0057-F compliant Payer-to-Payer FHIR R4 Bulk Data Exchange API, adding critical functionality for member data transitions between health plans. The implementation includes consent management, Azure-native async workflows, NDJSON bulk data handling, and reconciliation logic with PDex member matching.
Key Changes:
- New Payer-to-Payer API with bulk export/import operations, member consent validation, and Azure Service Bus integration for async processing
- Synthetic FHIR bulk data generator producing US Core compliant test resources (Patient, Claim, Encounter, EOB, ServiceRequest)
- 27 comprehensive tests covering consent management, bulk workflows, NDJSON serialization, and US Core validation (all passing, bringing total to 193 tests)

The consent registry uses a composite key patientId:targetPayerId, but then stores an array of consents and searches for duplicates. Since the key is already unique per patient-payer pair, storing an array is unnecessary complexity. Consider simplifying to Map<string, MemberConsent> and directly setting/getting the consent without the array wrapper and duplicate search logic. This would make the code cleaner and more efficient:
async registerConsent(consent: MemberConsent): Promise<void> {
const key = `${consent.patientId}:${consent.targetPayerId}`;
this.consentRegistry.set(key, consent);
}

Applied in commit 0b1531e. Simplified consent registry to Map<string, MemberConsent> and removed the unnecessary array wrapper and duplicate search logic. This makes the code cleaner and more efficient.

This change was already applied in commit 0b1531e. The consent registry is now using Map<string, MemberConsent> with direct set/get operations, without the array wrapper or duplicate search logic.

The PR description states dependencies as:
{
"@azure/service-bus": "^7.9.0",
"@azure/storage-blob": "^12.17.0",
"@azure/identity": "^4.0.0"
}However, the actual versions differ:
@azure/service-bus:^7.9.5(actual) vs^7.9.0(PR description)@azure/storage-blob:^12.29.1(actual) vs^12.17.0(PR description)@azure/identity:^4.13.0(actual) vs^4.0.0(PR description)
While the actual versions are acceptable and likely more recent, the PR description should be updated to match the actual dependencies for accuracy.
