  # step (five library steps; edge dependency audit + five build steps) with zero
  # GitHub Actions spend.
  # The workflow exports MIX_ENV: test at the JOB level, so every step here
  # re-execs mix under MIX_ENV=test via env(1) — a bare local `mix ci` would
  # otherwise boot in :dev, and a :dev compile skips test/support (the
  # warnings trap). `mix cmd` aborts on the first non-zero step, like a failed
