Pattern Proposal: Sequential Flow Pipeline Runner

Summary

Orchestrates multi-phase architecture workflows through a structured FlowRunner coordinating setup, extraction, evaluation, and reporting.

Candidate Pattern

• ID: sequential-flow-pipeline-runner
• Classification: intelligence
• Maturity: established
• Type: implemented

Observed Signals

No specific signals listed.

Evidence

Supporting Evidence

• src/cas_runner/runner.py (FlowRunner) - Main pipeline execution coordinator.
• src/cas_runner/cli.py (main) - Dispatches user CLI arguments to the runner.

Scope Assessment

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

Rationale

• Intent: Maintain deterministic execution order across extraction, compliance validation, and dashboard rendering.
• Context: Main execution engine instantiated from src/cas_runner/cli.py to run local and CI tasks.
• Force: Complex workflows risk inconsistent state if agent tasks execute out of order
• Force: Failures at early stages (e.g. git diff extraction) must abort before calling LLM APIs
