Pattern Proposal: Centralized Step-Pipeline Orchestration

Summary

Orchestrates multi-phase architecture steering runs through an explicit FlowRunner controlling step execution order.

Candidate Pattern

• ID: centralized-flow-runner-orchestration
• Classification: execution
• Maturity: established
• Type: implemented

Observed Signals

No specific signals listed.

Evidence

Supporting Evidence

• src/cas_runner/runner.py (FlowRunner) - Main execution coordinator for continuous architecture runs.
• src/cas_runner/cli.py (main) - CLI entry point initiating FlowRunner.

Scope Assessment

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

Rationale

• Intent: Provide a predictable, reproducible execution backbone for bootstrapping, delta parsing, agentic reconciliation, and compliance checks.
• Context: src/cas_runner/runner.py invoked from CLI and GitHub workflows.
• Force: Ad-hoc agent task loops produce nondeterministic ordering and difficult debugging
• Force: CI systems require predictable exit codes and linear step logs
