Pattern Proposal: Sequential Flow Pipeline Orchestration

Summary

Executes complex governance and build workflows through a deterministic pipeline coordinator passing shared state across steps.

Candidate Pattern

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

Observed Signals

No specific signals listed.

Evidence

Supporting Evidence

• src/cas_runner/runner.py (FlowRunner) - Main pipeline runner coordinating execution flows.
• src/cas_runner/cli.py (main) - CLI triggering runner sequences.
• docs/architecture/cas-automated-run-flow.md - Documentation specifying the sequential automated run stages.

Scope Assessment

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

Rationale

• Intent: Coordinate multi-stage architectural evaluation and generation tasks deterministically without allowing unconstrained dynamic loops.
• Context: Automated workflow execution for validation, steering projection, and documentation generation.
• Force: Unconstrained dynamic agent planning frequently produces infinite loops or non-deterministic step ordering
• Force: Architecture governance requires strict ordering (e.g., validate rules before updating portal state)
