Add PRML manifest schema

[sk8ordie84]

What

Adds an entry for PRML - Pre-Registered ML Manifest to the SchemaStore catalog.

PRML is an open CC BY 4.0 specification for committing machine-learning evaluation claims to a SHA-256 hash before the experiment runs. It is used by researchers, audit firms, and AI evaluation programmes to make threshold and dataset commitments cryptographically verifiable.

Diff

src/api/json/catalog.json, alphabetically near .pre-commit-hooks.yml:

{
  "name": "PRML manifest",
  "description": "Pre-Registered ML Manifest - open spec for committing ML evaluation claims to a SHA-256 hash before the run (CC BY 4.0). https://spec.falsify.dev/v0.1",
  "fileMatch": ["*.prml.yaml", "*.prml.yml", "manifest.prml.yaml", "prml-manifest.yaml", "prml-manifest.yml"],
  "url": "https://spec.falsify.dev/schema/prml-v0.1.schema.json",
  "versions": {
    "v0.1": "https://spec.falsify.dev/schema/prml-v0.1.schema.json",
    "v0.2-rfc": "https://spec.falsify.dev/schema/prml-v0.2.schema.json"
  }
}

Schema verification

• Draft: JSON Schema 2020-12
• $id matches URL: [OK] verified
• JSON valid: [OK] python3 -c "import json; json.load(open('catalog.json'))"
• Validates own examples: [OK] both v0.1 and v0.2 schemas include working manifest examples
• Validates against locked test vectors: [OK] 32/32 (12 v0.1 + 8 v0.2 + 12 v0.1 inputs against v0.2 for backwards-compat)

The schema URLs are served via Cloudflare Pages from a dedicated subdomain controlled by Studio 11. They have been live since 2026-05-09 and are part of the stable spec.falsify.dev deployment.

Where the schemas live

• Spec home: https://spec.falsify.dev/v0.1
• Schema landing: https://spec.falsify.dev/schema/
• v0.1 schema: https://spec.falsify.dev/schema/prml-v0.1.schema.json
• v0.2 schema: https://spec.falsify.dev/schema/prml-v0.2.schema.json
• GitHub: https://github.com/studio-11-co/falsify (CC BY 4.0 spec, MIT reference impls)

File pattern justification

All five patterns include the literal string prml to avoid collisions:

• *.prml.yaml, *.prml.yml - extension convention for PRML-formatted files
• manifest.prml.yaml - when paired with other manifests in the same project
• prml-manifest.yaml, prml-manifest.yml - community convention for the canonical filename

No overlap with existing entries in the catalog.

Maintainer commitment

I am the editor of the PRML specification and a co-founder of Studio 11 Turkey Ltd. Sti., which maintains the four reference implementations (Python, JS, Go, Rust). Contact: hello@studio-11.co. The schemas are CC BY 4.0; the reference implementations are MIT; an irrevocable patent non-assertion grant is published with the spec.

If the schema URLs ever need to be re-homed, I will submit a follow-up PR to update the catalog.

Disclosure

Self-submission per SchemaStore norm. Maintainer of the schemas, not affiliated with the SchemaStore project.

Happy to revise file patterns, description, or version-block structure based on reviewer preference.
