Command center (home)
Command center is your daily operator view. It leads with a Decision queue (up to five prioritized items — what happened, why it matters, impact, recommended action, whether Engine can act, and owner), a learning banner during the 14-day baseline period, six intelligence module statuses, today's operator summary, the setup or daily briefing, executive briefing on Scale, health scores with peer benchmarks on Growth+, and recommended Engine playbooks when both apps are installed.
