Pattern Proposal: Centralized Flow Runner Pipeline

Summary

FlowRunner acts as a centralized pipeline entry point for CAS flow execution.

Candidate Pattern

• ID: centralized-flow-runner-pipeline
• Classification: intelligence
• Maturity: strategic_direction
• Type: emerging

Observed Signals

No specific signals listed.

Evidence

Supporting Evidence

• src/cas_runner/runner.py (FlowRunner) - Defines the central execution runner.
• src/cas_runner/cli.py (main) - Provides the CLI entry point that likely invokes the runner.
• docs/architecture/cas-orchestration-flow.md - Architecture document path indicates an orchestration flow design.
• docs/architecture/cas-execution-sequence.md - Architecture document path indicates an execution sequence design.

Scope Assessment

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

Rationale

• Intent: Provide a single place where multi-step execution is ordered, validated, and observed.
• Context: The runner module exposes FlowRunner, the CLI exposes main, and architecture documents describe orchestration and execution sequences.
• Force: Execution order must be explicit.
• Force: Errors and governance checks need a common stopping point.
• Force: Distributed agent autonomy is not evidenced, so central control keeps behaviour predictable.
