One live plan for human judgment and agent leverage.
Gather is a multi-person decision engine for group retreats. Humans define what must be true; an external agent explores thousands of combinations; Gather validates every hard constraint; a human approves the consequential result.

“Read this live Gather decision room, including the stakeholder proposals and the latest human decision. Keep Costa Rica and Canopy House, improve Toronto travel fairness with no more than $4,000 added cost, and keep experience at 90 or higher. Search the plan space, show me three trade-off finalists, and explain the Decision Receipt.”
Expected proof: the finalists, Decision Receipt, and shared activity trail update in this page—without button automation.

Stakeholders propose changes; only a human can accept or decline them. The next agent read receives the exact decision and state version.
