Pattern Proposal: Declarative Transition Registry and Action Engine

Summary

Encapsulates valid lifecycle transitions and actionable governance tasks within a centralized Transition Registry and execution engine.

Candidate Pattern

• ID: declarative-transition-registry
• Classification: architectural
• Maturity: emerging
• Type: emerging

Observed Signals

No specific signals listed.

Evidence

Supporting Evidence

• src/cas_runner/governance/governance_action_engine.py (TransitionRegistry, GovernanceActionEngine) - Houses the registry defining state transitions and the engine that executes verified governance actions.

Scope Assessment

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

Rationale

• Intent: Prevent invalid status transitions of governance entities and provide a single dispatch point for lifecycle actions.
• Context: Architectural artifacts (e.g., decisions, patterns, rules) progress through statuses (e.g., proposed, accepted, deprecated). Actions must ensure transitions adhere to enterprise governance constraints.
• Force: Ad-hoc state modifications across disparate modules lead to corrupted lifecycle states.
• Force: Need for auditing transition outcomes and providing traceable metrics.
