Summary

Separate C API linting from the generic workspace Clippy invocation:

• Exclude rustpython-capi as a selected workspace Clippy target.
• Run cargo clippy --locked --all-targets -- -Dwarnings from crates/capi.

Cargo invoked at the workspace root does not load member-crate configuration. The dedicated invocation uses the existing crates/capi/.cargo/config.toml: PYO3_NO_PYTHON=1 and the RustPython 3.15 RustPython-abi3t-3.15 PyO3 configuration. No new feature or ABI fallback is introduced. Root benchmarks retain their independent configuration.

The C API library can still be a dependency of another selected workspace crate. The exclusion separates its explicitly selected test/example/bench targets from the root build context; it does not remove all C API production code from the workspace dependency graph.

The edited steps are shared by Linux and conditional macOS/Windows Clippy. Existing filters, matrices, environment, caches, permissions, features, exports, fixtures, and runtime test commands are unchanged. This is complementary to #9270's build/export work, not a modification of its contributor branch or a replacement for its export inventory.

Validation

• Normal repository hooks passed.
• Existing YAML parser confirmed shared Clippy anchors and unchanged other jobs; reversing the exact fragment restores the baseline bytes.
• Offline zizmor 1.31.1 reports the same four existing low-severity self-repository findings on baseline and candidate (exit 12 on both). No new findings or suppression changes; this is not a clean scan.
• Bounded Linux compile-only validation passed: cargo clippy --locked --offline --all-targets -- -Dwarnings, invoked from crates/capi with the existing ABI3T configuration.

No local C API tests, interpreter startup, lifecycle operations, or other runtime tests are executed. --all-targets compiles targets; it does not run tests. Linux lint evidence does not establish Windows/macOS or runtime correctness. Standard existing hosted CI remains responsible for its unchanged jobs on the new head.

AI assistance: OpenAI Codex, disclosed in the commit trailer.

Local lint validation used the exact candidate based on f3c443a. Before publication, main advanced to 30b8239d only through unrelated wasm JavaScript package updates (#9377 and #9378); workflow, Cargo and C API inputs were unchanged. The tested candidate was not rebased. Hosted CI must validate its actual merge context separately.
