 - **Always use `soldr` or `uv run soldr` to execute Rust commands.** Bare cargo/rustc and legacy `uv run cargo` shims are blocked by hook. soldr uses `rustup which` to pick the rustup-managed toolchain from `rust-toolchain.toml`. The standard Cargo path is `soldr cargo ...`, so repo Rust builds get soldr's managed zccache path by default; do not add repo-specific `RUSTC_WRAPPER` wiring for normal builds.
 - **Always use `uv` for Python.** Bare `python`/`pip` are blocked by hook. Use `uv run ...` or `uv pip ...`.
