4-bullet brief | narrative

Polymarket prices only 3% on North Korea invading South Korea before 2027, a deep long-shot despite the diplomatic shift.
Trump cutting drills short and praising Kim Jong Un is a significant security signal, but markets are not pricing an imminent invasion scenario.
The news and market pricing diverge in magnitude, the geopolitical gesture is real, but the Polymarket contract shows no escalation pricing.
Resolves via UMA oracle on a confirmed North Korean military invasion, a high evidentiary bar that keeps the contract anchored near zero.
