Pattern Proposal: Rule-Grounded Compliance Evaluation

Summary

Evaluates code and architectural delta compliance by evaluating diffs against codified rule contexts and generating structured finding metrics.

Candidate Pattern

• ID: rule-grounded-compliance-evaluation
• Classification: intelligence
• Maturity: strategic_direction
• Type: emerging

Observed Signals

No specific signals listed.

Evidence

Supporting Evidence

• src/cas_runner/governance/compliance_engine.py (ComplianceEngine) - Evaluator applying rules to codebase deltas
• src/cas_runner/governance/models.py (ComplianceFinding, ComplianceMetrics) - Data contracts for individual violations and composite scores

Scope Assessment

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

Rationale

• Intent: Continuously verify whether repository changes conform to organizational architectural standards before PR merge.
• Context: Within CI workflows (e.g. cas-build-validation.yml), PRs must be audited against cas-knowledge architectural rules.
• Force: Human architectural reviews are infrequent and slow down deployment velocity.
• Force: Purely static linting tools cannot evaluate architectural intent or semantic compliance.
