}Get the generated harness support snapshot
Returns the exact deployed harness catalog together with a deterministic catalog digest, the current experience, conformance, evidence-manifest, and readiness revisions, and one derived support record per entry. Catalog supply and signed catalog readiness are reported separately. Every row remains preflight_required for an actual harness/model/sandbox tuple; a recipe, capability ceiling, or tier never becomes a compatibility claim.
Checkfu support posture: alpha; hosted. Required evidence journey: support-registry. Deployment-specific readiness and the latest proven release are available from GET /v1/support/capabilities.
