Roadmap
The open-source path for approval-gated FHIR agents
Last EHR is intentionally narrow: chart reads, explicit write proposals, backend-enforced permissions, and no chart database in the layer. The roadmap expands that pattern without turning the project into an EHR.
Demo to Local
Keep the no-signup demo sharp, make HAPI local mode repeatable, and measure where evaluators drop off.
Backend Portability
Add well-tested adapters for Aidbox, Oystehr, Firely, and other FHIR R4 backends through the FhirBackend contract.
Approval Workflows
Improve proposed-write previews, rejected-proposal handling, and policy hooks without weakening explicit human review.
Clinical Tool Catalog
Expand beyond notes and observations carefully: Task, DocumentReference, encounter context, and better unit/coding support.
MCP Safety
Keep MCP read-only by default, add clearer tool annotations, and package the server once the surface stabilizes.
