/blueprint

Design the system architecture for the chosen approach.

Behavior

1. Read proposals.md and the chosen approach.
2. Produce architecture.md covering:
   • Components and their single responsibilities
   • Data flow (sources → transforms → sinks; for ML: data → features → model → serving)
   • Interfaces between components (well-defined boundaries)
   • Key decisions and their rationale
   • Risks and mitigations
   • Which sigma domains own which components
3. Favor small, isolated, independently-testable units.

Rules

• Each unit: what it does, how it's used, what it depends on.
• Call out coupling (CACE) for ML systems.
• Diagrams in mermaid where useful.
