What works today, and what doesn't yet.
Cascade is alpha. This page is the one place we state it precisely.
§ 1
The ledger
Works today
- Import FHIR R4, C-CDA and Apple Health exports into a pod.
- Validate any record against the published SHACL shapes.
- Read and write pods from TypeScript and Python.
- Encrypt a pod at rest with a passphrase (CLI, opt-in).
- Serve a pod to an AI assistant over MCP, with a call log.
In progress
- SDKs catching up to the newest vocabulary versions (clinical 1.16 to 1.21).
- Pod encryption format: Draft 1.1. File swaps and rollbacks aren't detected yet.
- Five draft vocabularies: advisory, diabetes, evidence, genomics, workbench.
Not built
- Sharing and consent controls. Today you share by exporting a file you choose.
- Signed exports. An export is valid unsigned.
- A public Swift SDK. An early private version runs inside POTS Check only.
- Cascade Bridge as an app. It is a design, submitted to the ONC EHIgnite Challenge.

Within a vocabulary's major version, a record that validated still validates. Versioning policy

Roadmap
What we're building next.
Apps

- Cascade Workbench in development: the place those records come together.
Developer experience
- Quickstarts tested against each release.
- SDKs brought up to the current vocabularies.
Specification
- The spec roadmap is coming soon. Until then, follow the decision records ↗.
