ReadonlyapplicationOptional ReadonlyconnectionReads the databases behind direct connections (PLAN §6.8); without one, the source picker offers no database connection
Optional ReadonlydataThe deployed data products (PLAN §6.8); without one, the source dialog offers no data products
ReadonlyengineOptional ReadonlyengineThe engine URL and request compression its engine clients share, which Dev Settings changes (PLAN §11.16); without them, Dev Settings can't change either
Optional ReadonlyingestThe deployed ingest definitions (PLAN §6.7); without one, the source dialog offers no ingest data sets
ReadonlymodelOptional ReadonlyoffersWhether the page offers Cube's sample data: the source dialog's Sample Data tab and the Examples. Offered unless the host says no, as Studio does, where a cube reads only the project's ingest definitions
Optional ReadonlyprojectThe one project whose own sources the page reads, e.g. the one Studio edits: the source dialog lists its ingest definitions and data products by name and path, with no class, deployment or search across the platform, and says which lakehouse runtime its runs use
Optional ReadonlyprojectThe published projects in the host's depot (PLAN §6.3); without one, the source dialog offers no projects
Optional ReadonlyserviceThe deployed services (PLAN §6.4), in progress; without one, the source dialog offers no services
What the application hosting the Cube page gives it (PLAN §3.5, Settled before M1.8). The host chooses the engine and the models; Cube keeps no auth, config or telemetry of its own and uses the host's application store for commands, user data, the clipboard, the theme, notifications, alerts and telemetry.
