    # `qa` is the release candidate — it runs these too, plus the expensive
    # suite in qa.yml. `main` only ever moves at release time, to a tagged

  # ── Did this change break anything downstream? ──────────────────────────────
  #
  # Every job above proves libfreemkv builds. None proved its DEPENDENTS do,
  # and that gap is real: an engine signature change broke autorip today and
  # went unnoticed because consumer CI only fires on a push to that consumer.
  # libfreemkv sits below all five of them, so a break here is worth strictly
  # more than a break anywhere else in the project.
  #
  # `cargo check --all-targets` only — each dependent owns its own behaviour
  # and has its own suite. The question here is just "does everything built on
  # me still compile against this commit".
