4-bullet brief | narrative

The Polymarket contract puts only an 8% chance that Trump, Putin, and Zelensky appear together before 2027.
Trump signing Russia sanctions into law is a hawkish signal that makes a tripartite diplomatic summit more, not less, difficult near-term.
The market is not treating the sanctions bill as a bridge to peace talks; the 8% probability is consistent with the hardened posture.
Resolves via uma_oracle; the companion Polymarket contract on Putin remaining president sits at 95% probability, removing leadership-change tail risk from the equation.
