scorecard produces a 0–100 risk score from weighted factors. Each factor is a path into the run context with a list of cases mapping observed values to sub-scores. The final score is the weighted sum of sub-scores.

How the score is computed

For each factor: evaluate the cases top-down, take the first match’s score as the sub-score. Then: 
final_score = sum( sub_score[i] * weight[i] ) / sum( weight[i] )
In the example above, weights total 100; the final score is the weighted average mapped onto a 0–100 scale.

​
extractSubScores

When true, each sub-score is also written to the run context under <outputField>_<factor_id> — e.g. risk_score_factor-1, risk_score_factor-2, risk_score_factor-3. Used to make the score’s components inspectable in downstream nodes and audit logs.

Scorecard vs AI synthesis

ScorecardAI synthesis
Determinism100% (same input → same output)High but not perfect (temperature 0.1)
Reasoning trailImplicit (sub-scores)Explicit (reasoning field)
Handles unstructured signalsNoYes (adverse media text, document narratives)
Easy to defend in regulator interviewYesYes — with the prompt + temperature config
Best forStructured velocity / device / identity-confidence signalsBorderline cases combining heterogeneous signals
Production workflows commonly combine both — a scorecard handles the cleanly-structured factors, an AI synthesis layer handles the borderline cases that need narrative reasoning.
