fix(ci): Match Rust's z10 baseline in s390x release builds (#12489)   **Description:** The s390x core and React Compiler release builds fail while assembling `psm 0.1.21`. The GCC compiler from `@napi-rs/cross-toolchain-x64-target-s390x@1.0.3` rejects the `lay` instructions and a negative displacement in `zseries_linux.s` with its default architecture. Set `CFLAGS_s390x_unknown_linux_gnu=-march=z10` in the s390x build script to match Rust's default target CPU. The setting covers the core CLI and all four native addons. Add a regression test that executes each product's build branch with stub commands and checks the compiler flag at every invocation. This changes release tooling only. The changeset has no crate version bumps. Validation: - `node --test scripts/native/workflow.test.mjs`: 8 passed. The new test fails when the compiler setting is removed. - `node --test scripts/native/*.test.mjs`: 23 passed, 1 Windows-specific test skipped on macOS. - `cargo fmt --all`: passed. - `cargo clippy --all --all-targets -- -D warnings`: passed. - Prettier and `git diff --check`: passed. - In a Linux amd64 Docker container, the exact CI cross-toolchain reproduces all three assembler errors without the flag. With `-march=z10`, the same `psm` assembly produces an IBM S/390 ELF object successfully. A complete native release build has not been run locally. PR CI is pending. **Related issue (if exists):** Failed workflow: https://github.com/swc-project/swc/actions/runs/37578353726

fix(cli): resolve out-dir source map paths relative to output (#12481) **Description:** The native Rust CLI currently retains cwd-relative source names in maps emitted with `--out-dir`. For example, `lib/src/index.js.map` refers to `src/index.ts` instead of `../../src/index.ts`, so the path resolves inside the output tree. Resolve each output destination before transformation and pass it through `Options.output_path`. Compute source-map names separately from normalized input and output paths to preserve input filenames, JSX development metadata, and explicit source-name/root overrides. This covers external and inline maps as well as watch rebuilds. Validation: - Confirmed the new reproduction test fails before the fix. - `cargo test -p swc_cli_impl`: 42 tests passed, including 12 new regression tests. - `cargo fmt --all` - `cargo clippy --all --all-targets -- -D warnings` **Related issue (if exists):** Fixes #12480

chore(ci): allow TSRX contributors (#12482)  **Description:** Add `trueadm` to a dedicated `tsrx` contributor group so TSRX pull requests and CI runs are accepted by the contributor policy. The account is identified by the TSRX introduction commit `61ff097706` and merged PR #12120. Extend the existing contributor-policy fixtures to verify that `trueadm` and `TRUEADM` are allowed in the `tsrx` group without repository permission lookups. Also assert that the repository allowlist contains the account in that group. No Rust crates or release metadata are affected, so no release changeset is needed. Validation: - Initialized submodules with `git submodule update --init --recursive`. - Ran `npm ci --ignore-scripts --no-audit --no-fund` and `npm test` in `.github/actions/contributor-policy` under Node.js 24; all 89 tests passed. - `cargo fmt --all` passed. - `cargo clippy --all --all-targets -- -D warnings` passed. - `git diff --check` passed. **Related issue (if exists):** Follow-up to #12463 and #12467; TSRX implementation: #12120.
