Build And Test Rust Core

Companion Guidance

Use karpathy-guidelines alongside this skill for implementation or review work. Keep changes scoped, surface assumptions, and define focused validation before editing.

Use this skill when a change is primarily in crates/core, crates/adaptive, or shared Rust runtime semantics.

Default Path

1. Run cargo fmt --all.
2. Run just test-rust.
3. Run cargo clippy --workspace --all-targets -- -D warnings.
4. Because this skill covers crates/core, crates/adaptive, or shared runtime semantics, expand to the full binding matrix with validate-change.
