Feature status
This page distinguishes what the repository implements today from the work still needed for broader production operation.
Implemented
Section titled “Implemented”| Area | Current capability |
|---|---|
| Identity registry | Source Patient ingestion, UUIDv7 enterprise identities, Person links and canonical Patient survivorship |
| FHIR R4 | Patient create, update, read, search and $match; Person lookup; JSON/XML; ETags and OperationOutcome |
| HL7v2 | MLLP ingestion for ADT A01, A04, A08, A28, A31, A40 and A47 |
| Matching | Configurable bounded blocking rounds, field weights, thresholds, identifier certainty and hard-conflict handling |
| Review | Explainable probable-match cases, merge, reject, unlink/split, stale-case detection and dual approval |
| Tenancy | Trusted tenant and source context on every identity, query, receipt, decision and audit event |
| Storage | Development in-memory provider and durable GCP Healthcare API R4 provider behind one contract |
| Operations | Blazor portal, source trust, policy editing, audit search, health checks and OpenTelemetry |
| Deployment | Containers, Compose, Helm, Terraform foundations and a reproducible GCP demo |
Deliberate gaps
Section titled “Deliberate gaps”| Capability | Status |
|---|---|
| Online batch re-index after blocking-rule or key changes | Not implemented |
| Scheduled population reconciliation | Not implemented |
| Ground-truth recall and precision reporting | Not implemented |
| Nickname dictionaries and additional comparator libraries | Not implemented |
| Fellegi–Sunter probability calibration | Not implemented |
| Adaptive or trainable ML classification | Not implemented |
| Arbitrary non-patient entity resolution | Out of scope |
| Broad webhook and integration catalogue | Not implemented |
| Certified clinical product status | Not claimed |
The next safety-critical platform capability is controlled batch re-indexing. Until it exists, changing blocking inputs or authoritative identifier systems for a populated registry requires an offline migration plan.
Read the matching rules for exact behaviour and production readiness for the controls that remain the deploying organisation’s responsibility.
