"550e8400-e29b-41d4-a716-446655440000"
Monotonically increasing version number, unique per agent.
x >= 1Format version of the config document recorded for this version.
Content hash of the version's config document.

Optional human-readable label.
120Canonical agent configuration document, exactly as produced by the agent config download endpoints. The document is a portable, secret-free representation of the agent's configuration; webhook auth is carried as organisation Vault secret references. Treat it as an opaque file: download, store, and re-import it without modification.
Issues detected when re-validating the stored config against the organisation's current resources.
