Implementations

Independent tools that implement JPS document conformance. A listing here records that a tool exercises the public specification; it is not certification, endorsement, or authority over the specification.

The specification is the authority. No implementation — including the reference runtime — is normative. Passing a tool's checks establishes only what that tool reports about the JPS document layers, never factual grounding, authorization, safety, or fitness. Any implementation that passes the public conformance corpus is equally valid.

Available implementations

Open source · Apache-2.0 · maintained with the specification

judgment-pack

The project's vendor-neutral reference runtime. It validates the carrier, structural schema, and semantic references of a JPS document against an immutable specification release. It does not evaluate rules, choose an outcome, fetch a source, or authorize an action.

This list is open to independent implementations tested against the public conformance artifacts. Presence here does not confer certification, official-validator status, endorsement, or authority over the specification.
