  # Tests run as a PARALLEL TRIPWIRE: they fail the run if they fail, but the

  # the local precommit (same Rust 1.86, same commit).
  #
  # freemkv-keysources is a library — Cargo.lock isn't tracked, so --locked
  # would always fail (no lockfile to lock against on a fresh runner). Its
  # libfreemkv dep resolves from crates.io (the dev .cargo/config.toml patch is
  # gitignored and absent on the runner), so libfreemkv must already be published
  # at this version — the release script enforces that ordering before tagging.

  # NOTE: the crates.io publish is driven by the maintainer's release tooling
  # from local credentials, not from CI — this repo has no CARGO_REGISTRY_TOKEN
  # secret. release.sh runs `cargo publish --no-verify` locally. CI here only
  # verifies the version/tag match, runs tests (tripwire), and cuts the GitHub
  # Release. The binaries git-tag-pin keysources, so they don't wait on the
  # crates.io publish — it serves external consumers in parallel.

  release:
    # Only needs `verify`; the GitHub Release is cut as soon as the version
    # check passes, in parallel with the test tripwire.
