+2. **Decision**: pick one of the 47 demos (tabs group them into triage, routing and planning, loop control, guardrails, and agent security (nano set)) or write your own state and questions. Nothing is executed; every demo is a decision only. Questions use the Laya/Jev JSON shape:
    ```json
    {"team":    {"type": "choice", "instructions": "Which team?", "criteria": {"bug": "Something is broken", "sales": "Pricing"}},
     "urgency": {"type": "score",  "instructions": "How urgent?", "criteria": ["Can wait", "Today", "Right now"]},
     "angry":   {"type": "noul",   "instructions": "The customer sounds angry"}}
    ```
 3. **Verdicts**: one probability bar per model for every option, each model's answer, confidence, an *act* or *defer* badge against your threshold, and how many models agree.
-4. **Scoreboard** runs all 24 demos (54 questions) or one group. It highlights the best model on each metric (reference matches, median time, answers acted on, correct when acting, confident mistakes, mistakes deferred) and ranks every model by the **Agentic Use Score** below, then breaks matches and confident mistakes down by group.
+4. **Scoreboard** runs all 47 demos (88 questions) or one group; only the 54 questions with reference answers count toward matches and the Agentic Use Score. It highlights the best model on each metric (reference matches, median time, answers acted on, correct when acting, confident mistakes, mistakes deferred) and ranks every model by the **Agentic Use Score** below, then breaks matches and confident mistakes down by group.
 
 **Confidence.** LightDec and Arthur models report the probability of their top option (Arthur's is temperature-calibrated per question type and option count). Laya reports 1 − normalised entropy for choice and score questions, and the larger of P(yes) and P(no) for yes/no questions. The lab computes both definitions for every model; pick one with the *Confidence means* selector.
 
 ## Demos
 
-24 demos in 4 groups. The tab numbers match the table.
+47 demos in 5 groups. The tab numbers match the table. Demos 25–47 are the **Agent security (nano set)** group: the states and questions of the Athr_Agent_Sec nano demo set (`app/demos_nano.json`), with no reference answers, so they show each model's answers, confidence and agreement but are not scored for matches.
