The rulebook

The catalog validates every built-in and plugin rule before execution. It checks identity, numbering, dependencies, policy, settings, repairs, and documentation.

Every rule docstring follows one contract.

Summary

Definition
Evidence
Exceptions
Examples
References

The definition states the judgment. Evidence explains what a finding records. Exceptions describe intentional quiet cases. Examples make the boundary concrete. References are parsed into named and linked sources.

The Rule reference is generated directly from these docstrings on every docs build. Each page links to the exact implementation line and every cited URL. Catalog and docs therefore cannot drift through manual copying.

catalog exports the typed catalog as JSON. coverage maps rules from upstream tools to native, delegated, adapted, inapplicable, or unavailable support. replacement audits frozen legacy capabilities against successors. influence shows which sources shaped the rulebook.

When DataHub writeback is enabled, one shared rule entity records which repositories run it and their latest verdicts. See What gets published.
