Pattern Proposal: Sequential Flow Orchestration Pipeline

Summary

Coordinates multistep architectural governance and compliance execution through a centralized sequential pipeline passing shared context between stages.

Candidate Pattern

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

Observed Signals

No specific signals listed.

Evidence

Supporting Evidence

• src/cas_runner/runner.py (FlowRunner) - Centralized execution runner managing stage lifecycles
• src/cas_runner/cli.py (main) - CLI driver delegating arguments to FlowRunner

Scope Assessment

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

Rationale

• Intent: Ensure deterministic ordering and dependency propagation across initialization, analysis, evaluation, and publishing stages.
• Context: Continuous architecture analysis involves multi-stage tasks (bootstrap, lint/validation, LLM evaluation, report generation) where downstream steps rely on upstream outputs.
• Force: Uncoordinated multi-agent parallel execution can cause race conditions on file-based state.
• Force: Failures in early validation steps must immediately short-circuit expensive LLM operations.
