  "description": "The agent cannot finish all 30 emails within 360 minutes — it must decide which to skip. Time-trap emails (up to 180 min) appear even from VIPs, meaning blind VIP-always-respond is punished. Angry follow-ups cascade from repeat VIP ignores. A sunset penalty deducts reward for every high-priority email left unfinished. The agent must balance time efficiency, relationship health, AND priority accuracy simultaneously.",
