  # Tests run as a PARALLEL TRIPWIRE: they fail the run if they fail, but the
  # release job does NOT `needs:` this job. The tag decision was already gated by
  # CI (ci.yml on dev, then a green qa.yml on the same commit).
  #
  # Cargo.lock is now committed (issue #15), but --locked is still omitted: on
  # the runner the libfreemkv dep resolves from crates.io, not the local path
  # patch, which --locked can't reconcile. 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 — release-orchestrate.yml enforces that ordering before tagging.

  # NOTE: there is no crates.io publish — keysources is `publish = false` and
  # git-tag-only. Consumers git-tag-pin it via a committed [patch.crates-io], so
  # the git tag itself is the release artifact. CI here only verifies the
  # version/tag match, runs tests (tripwire), and cuts the GitHub Release.

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