nucleus-substrate-sdk vs nucleus-substrate-cli vs nucleus-substrate-core
Side-by-side comparison of Rust crates
Demand-side SDK for the Nucleus substrate. Async HTTP `Client` over the hub plus a single `verify_receipt_fully` entry that walks all four projections (Identity, Capability, Flow, Economic) of a Receipt. Composes substrate-core + identity-projection + flow-projection + mechanism-vcg.
Command-line client for the Nucleus substrate. Single binary `nucleus-substrate` driving offline receipt verification (signature + all-projections), live hub fetches, and counter inspection.
Categorical core of the Nucleus substrate: Session (the agent action), Projection (the verifiable record functor — Identity, Capability, Flow, Economic, …), and Receipt (the Ed25519-signed colimit). Lightweight, no runtime deps. See docs/architecture/substrate.md.
