dr_source_release()

Execution resolves an omitted release_id once and records its immutable identity. Pass a configuration to open an existing lake read-only, collect the selected release into an ordinary tibble, and close the owned connection. This requires enough memory for the release. A connected lake instead returns a lazy table and remains caller-owned; keep it open while using that table. Construction and validation do not open or create a lake. This source connects governed releases to ordinary product composition and consumer exports. When publishing back to the same lake, execution can reuse its open handle; configuration sources still return materialized values without owning it.
