| # PR / push CI: correctness, compliance, MSRV, headless, and a cheap build of | |
| # every shipped target so cross-platform breakage is caught per-PR instead of | |
| # at release time. | |
| # | |
| # Design decisions (full rationale in docs/build-and-release.md#ci): | |
| # - Scripts, not inline run-blocks, for anything longer than two lines: | |
| # contributors run scripts/ci-*.sh locally and get the identical result. | |
| # - Swatinem/rust-cache over manual actions/cache: it keys on the lockfile | |
| # AND toolchain AND target list, and prunes stale artifacts, which manual | |
| # cache keys always eventually get wrong. | |
| # - Every cargo invocation is --locked: CI must build what the lockfile | |
| # says, or the lockfile is fiction. | |
