      summary: What launching WOULD do, without doing it
      description: >-
        Mirrors the launch clause for clause: `will_send` (a forecast — consent
        is re-checked per message), `held` with the reason each group is staying
        put, `blockers` — the things launch refuses on — and
        `pending_templates`, templates still in Meta review, which do NOT block:
        people arm and sends start the moment approval clears. Check this before
        launching — launching sends real messages to real people.
