Why we built ONSET around "humans decide, machines execute"

When we started ONSET, we watched dozens of AI startups ship "autonomous" agents that quietly sent emails, posted to Twitter, and charged credit cards. None of their customers wanted that. They wanted a colleague who would draft the email, show it to them, and send it only when they nodded. So we baked it in: every outbound, financial or destructive action goes through a 30-second cancel window via Telegram. That's Mandate 2.4 and it isn't optional.
