# Contract directory

The canonical schema for each document kind is version v0.1. Formation policies
also support v0.2 for extensible topology vocabulary metadata. Unknown schema versions are
rejected with the supported versions listed in the error. The paths in the frontmatter are
the authoritative list; the prose below only repeats it.

## Catalogue pages

The reference pages this service publishes: the pattern catalogue, the task domains, research
records, the starter index and these guides. Nothing submits them; their schemas say what each
frontmatter field means.
