Pattern Proposal: Pure Health Evaluation Pipeline

Summary

Isolating health score computations and diagnosis reasoning into pure, side-effect-free evaluation functions.

Candidate Pattern

• ID: pure-health-evaluation-pipeline
• Classification: architectural
• Maturity: strategic_direction
• Type: emerging

Observed Signals

No specific signals listed.

Evidence

Supporting Evidence

• src/cas_runner/dashboard/health_model.py (HealthStatus, calculate_health, get_health_reasons) - Implements deterministic health calculation and diagnosis without I/O dependencies.

Scope Assessment

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

Rationale

• Intent: Decouple metric aggregation and health classification from I/O and state storage.
• Context: Dashboards and CI jobs need to determine workspace architectural health from runtime inventories without mutating workspace files.
• Force: Health checks must run quickly and deterministically across different execution contexts.
• Force: Testing health calculations should not require mocking filesystem or network calls.
