The published schema

The canonical risk object, the documents every verb answers with, and the map from response to schema. Fetch any of them here: no account, no key, no install. These are the same files Craton validates its own responses against, served byte for byte as the release carries them.

The file name carries the version line: risk-object.v0 reads every 0.x.y document, so a minor version never invalidates an object you already hold. /schema.json is the short URL for the risk object; validate.py validates a document against it with nothing but a Python 3 and this directory.
