Candidate Pattern

• ID: pydantic-governance-domain-modeling
• Classification: architectural
• Maturity: emerging
• Type: emerging

Observed Signals

No specific signals listed.

Evidence

Supporting Evidence

• src/cas_runner/governance/models.py (ResolutionResult, TraceableMetric, GovernanceInventory, GovernanceHealth, GovernanceThroughput, GovernanceRisks, ComplianceFinding, ComplianceMetrics, GovernanceException, GovernanceAction) - Defines the core governance domain vocabulary.
• pyproject.toml - Declares pydantic>=2.12.5 as a dependency.

Scope Assessment

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

Rationale

• Intent: Provide validated, serializable, and consistent representations of governance state.
• Context: The governance subsystem needs stable contracts for inventory, health, throughput, risk, compliance, and actions.
• Force: Data must be validated at boundaries
• Force: Domain concepts need a shared vocabulary
• Force: Models should be usable for metrics, findings, and persistence
