values:
  - name: root
    description: >
      Top-level trust anchor for the catalog federation. A root signer can
      authorize any quorum rule and is responsible for bootstrapping the signing
      key hierarchy. Root signers are typically the infrastructure operator or
      steward of the canonical catalog.

  - name: editor
    description: >
      Subject-matter contributor who authors or significantly revises atom
      content. Editors satisfy the editorial-review requirement in quorum rules
      (e.g. "1 of role:catalog-maintainer + 1 of role:editor" for design-spec
      atoms). An editor's signature attests that the content is technically
      correct and complete.

  - name: catalog-maintainer
    description: >
      Operator responsible for the ongoing health and consistency of the
      schema-atoms catalog. Catalog-maintainer signatures are required by the
      default quorum rule and by most class-specific rules. The catalog-maintainer
      attests that the atom conforms to the atom-schema-spec and catalog policy.

  - name: ratifier
    description: >
      Governance approver for atoms in controlled namespaces (e.g.
      "governance/*"). A ratifier's signature attests that the atom meets the
      governance criteria of the federation and that its promotion has been
      reviewed at the appropriate authority level.

  - name: mirror-operator
    description: >
      Operator of a federated mirror of the catalog. Mirror-operator signatures
      are used in federation protocols to attest that a mirrored atom has been
      received intact and verified against the canonical content hash. This role
      does not grant the ability to author or promote atoms.
