Module contracts 

User-facing Contract traits (Index, Backend, Aggregator, …). User-facing Contract traits — what a library maker implements when shipping a concrete component. The derives in bb-derive bridge these into the per-component dispatch_fn the engine holds.

Canonical home for bb-runtime. bb-dsl::contracts re-exports from here so the authoring path bb_dsl::Index keeps working.
