Nested Shape: Discovery.capabilities

PropertyTypeRequiredDescription
comments{ enabled: boolean; features?: Record<string, boolean>; description?: string }✅Whether the backend supports record comments / chatter (the sys_comment object served via the data API)
automation{ enabled: boolean; features?: Record<string, boolean>; description?: string }✅Whether the backend supports Automation CRUD (flows, triggers)

transactionalBatch{ enabled: boolean; features?: Record<string, boolean>; description?: string }✅Whether the backend exposes the atomic cross-object batch endpoint (POST {basePath}/batch, /ADR-0034): all ops commit or roll back together in one transaction. Lets clients skip non-atomic client-side simulation instead of runtime-probing 404/405/501. True ⟺ the /batch route is mounted AND the runtime can honour a transaction.
websockets{ enabled: boolean; features?: Record<string, boolean>; description?: string }✅Whether the backend mounts a realtime push surface (WebSocket/SSE) clients can subscribe to. False while realtime is an in-process bus with no mounted HTTP/WS surface (ADR-0076 D12).

analytics{ enabled: boolean; features?: Record<string, boolean>; description?: string }✅Whether the backend serves the analytics / BI query surface
