Output

json

{
  "busy_score": 0.32,
  "confidence": 0.65,
  "recommendation": "CHECK_IN",
  "ml_probability": 0.28,
  "evidence_details": ["ML Baseline (-0.5)"]
}

Scoring Logic

Uses Evidence Accumulation (log-odds):

Explicit busy intent: +6.0 weight
Traffic noise: +3.0
Emotion stress: +2.5
ML model probability: ×0.5 log-odds factor

Final score = sigmoid(total evidence)

Thresholds

Score < 0.3 → CONTINUE (person is free)
0.3 ≤ Score < 0.7 → CHECK_IN (uncertain)
Score ≥ 0.7 → EXIT (person is busy)
