Pattern Proposal: Sequential Flow Pipeline with Shared Context

Summary

FlowRunner executes a deterministic sequence of steps, passing a mutable context object.

Candidate Pattern

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

Observed Signals

No specific signals listed.

Evidence

Supporting Evidence

• src/cas_runner/runner.py (FlowRunner) - Orchestrator class
• docs/architecture/cas-orchestration-flow.md - Describes the orchestration flow

Scope Assessment

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

Rationale

• Intent: Enable stepwise agent execution with predictable ordering and shared state.
• Context: Core execution model for the CAS runner, as described in architecture docs.
• Force: Need reproducible flow execution
• Force: Steps may need to share state
• Force: Must allow adding/removing steps without breaking orchestration
