Pattern Proposal: Declarative Health Scoring Pipeline

Summary

Pure functional evaluation pipeline deriving health status and diagnostic reasoning from state metrics.

Candidate Pattern

• ID: declarative-health-scoring-pipeline
• Classification: architectural
• Maturity: established
• Type: implemented

Observed Signals

No specific signals listed.

Evidence

Supporting Evidence

• src/cas_runner/dashboard/health_model.py (HealthStatus, calculate_health, get_health_reasons) - Functional evaluation of health states and human-readable diagnostic reasons.

Scope Assessment

• Evidence Strength: high
• Confidence: high
• Applies to: ideas-to-life-cas

Rationale

• Intent: Compute deterministic health states and diagnostic explanations from input metrics without side effects.
• Context: Dashboards and CLI tools require consistent, explainable health diagnostics based on governance metrics.
• Force: Health computation rules should be isolated from presentation and persistence code
• Force: Health status must provide actionable, human-readable explanations alongside raw enum states
