"""DecisionLab demos: single decisions for system-1 decision models. Nothing is executed; each demo is a
state plus typed questions, and the lab only compares what the models would decide.

Demos are grouped by what the decision is for (see GROUPS):

Agent decisions
  triage      Customer and business triage: route, score and prioritise incoming messages.
              support-ticket, lead-scoring, patient-message, delivery-exception and product-review come from
              Vishal Mysore's "Jev vs Laya: Live Demo" (Medium, Sept 2026); support-ticket uses the exact state
              and questions from the layaForWeb README, the others are rebuilt from the article's descriptions.
  routing     Routing and planning: which tool, source or handler comes next, and whether a plan is sound.
  loop        Loop control and verification: stop, retry, fix or check the agent's own work.
  guardrails  Safety guardrails: irreversible actions, injection, fraud, data leaving, secrets, permissions.

`stakes`: questions marked "high" are safety-critical for an agent (irreversible, security or
money). The Agentic Use Score counts them twice.

`reference` is a careful human reading of each question, used for the scoreboard. It is a
judgement, not ground truth: choice/score -> option key, noul -> "true"/"false".
