| # `nix flake check` rather than `nix build`: it builds the package *and* | |
| # evaluates every `checks.*`, so fmt, clippy, the hermetic test suite, and | |
| # the `--help` smoke test all gate the PR from one entrypoint. | |

| # st2 drives real processes — process groups, signals, pipes, reaping — and those paths | |
| # are OS behaviour, not portable Rust: #356 and #255 were aarch64-darwin failures no Linux | |
| # run could have caught. The hosted macOS runner is arm64 with 3 cores, so it is also a | |
| # stricter scheduler than any Mac in the fleet, which makes it a good detector for | |
| # load-sensitive lifecycle tests. | |
| # | |
| # Narrower than its Linux sibling on purpose: `nix build .#st2` builds the package and runs | |
| # its hermetic suite via `doCheck` — the surface those issues live on — without also | |
| # demanding cold aarch64-darwin builds of the `pty` and `otelite` inputs that | |
| # `checks.parked-recovery` and `checks.otel-export` pull in. Widen once this is stable. | |
