OFFICIAL ARTIFACTS

Downloads & Releases

Direct access to the canonical schemas and the six reference manifests. The reference CLI and the SDK libraries are specified but not yet released, and nothing is listed here that cannot be downloaded.

1. Canonical JSON Schema Files

Version	Specification	Format	Action
MSR JSON v2.1.0	Draft 2020-12	`.json` (application/schema+json)	Download msr-2.1.json
MSR JSON v2.0.0	Draft 2020-12	`.json` (application/schema+json)	Download msr-2.0.json
MSR JSON v1.1.0	Draft-07	`.json` (Legacy PAD Bridge)	Download msr-1.1.json
MSR JSON v2.1-draft (superseded)	Draft 2020-12	`.json` (same as 2.1.0)	Download msr-2.1-draft.json

2. Reference CLI Binaries Not released

No binary has been published

The reference CLI is specified in the CLI reference but has not been built, signed or released, so this page lists no archive and no checksum. When the first release is cut, every artifact will carry its SHA-256 digest and a detached signature, reproducible from the tagged source. A digest published before the artifact exists would ask you to trust a number that verifies nothing, so none is published here.

Nothing is blocked in the meantime: the schemas above are the whole dependency, and the local recipe validates a manifest with independently published tools.

4. Schema Packages & Client SDKs

The canonical schema distribution is published on npm as @msrjson/schema. Validator libraries and client SDKs for other runtimes are currently in development under the reserved package identifiers below:

Language / Runtime	Package Name	Registry	Status
TypeScript / Node.js	`@msrjson/schema`	npm	Published v2.0.0 ↗
Python	`msr-validator`	PyPI	Planned
TypeScript / JS (SDK)	`@msrjson/core`	npm	Planned
Go	`github.com/msrjson/go-msr`	Go Modules	Planned
Rust	`msr-proto`	crates.io	Planned

To validate a manifest now, use the browser validator or check-jsonschema / ajv-cli.
