Group Chat Drama Triage

1/**
2 * Group Chat Drama Triage
3 * Pattern: speculative fan-out + composite scoring in code.
4 *
5 * Four independent reads of the same chat run in `parallel`. Because they share
6 * a state, the client merges them into ONE request automatically (Jev reads the
7 * state once and answers every question in parallel). Then plain code weighs
8 * the answers into a severity and a plan. Jev judges; your code decides.
