lcod-kernel-rs

Rust reference implementation of the LCOD kernel. It exposes:

• A lightweight Registry/Context to call contracts, implementations and flow blocks.
• Compose runner with slot orchestration and stream handles.
• Minimal tooling (demo registry, test harness) mirroring the JavaScript substrate.

See docs/runtime-rust.md in the spec repository for the architecture blueprint and current contract coverage. In short:

• Filesystem, hashing, parsing and stream contracts are implemented with parity tests.
• HTTP and Git bindings are implemented via curl/libgit2 and now power resolver-style flows end-to-end (buffered + stream responses, refs/depth/subdir handling).
• register_resolver_axioms(&Registry) aliases the available contracts under their axiom:// identifiers so the resolver example can run with the Rust substrate.

Running the tests

cargo test                 # kernel unit/integration tests
cargo run --bin test_specs # execute shared spec fixtures from lcod-spec/tests/spec

The spec fixtures require the lcod-spec repository to be accessible. By default we look for sibling directories; override with SPEC_REPO_PATH=/path/to/lcod-spec when running locally or in CI.

Shared fixtures

The reusable compose fixtures live under lcod-spec/tests/spec and are executed through both kernels. They rely on tooling/test_checker@1 and provide parity coverage across substrates (foreach demos, streaming, scripting, slots).
