    # process from one Actions step is dead by the next step, so `wait-on` hung

    # download failed on this runner) and NOT a job `container:` (this act_runner times out
    # pulling the base runner image for container jobs). `--break-system-packages` survives
    # PEP-668; pip drops `semgrep` on PATH. `--ignore-installed` is required because some of
    # semgrep's deps (e.g. PyJWT) are already present as apt-managed packages, which pip cannot
    # uninstall ("RECORD file not found") — this flag installs fresh without uninstalling, so it
    # never touches the Debian copies. Don't drop it.
    # ponytail: report-only for now (no `--error`, so the job stays green while the initial
    # findings are triaged); flip to `--error` to make it a blocking gate. See WP-30.
