LayersCopy Anchor Link

1. Overseer (Orchestrator)
   • Plans execution, manages continuations, routes tasks.
2. Router
   • Decides whether to run local (light) or heavy (RunPod/Docker).
3. Proctor
   • QA checks: schema validation, safety rules, acceptance tests, thresholds.
4. Workers
   • Light = provider wrappers (OpenAI/Gemini/DeepSeek) in Next.js.
   • Heavy = RunPod/Modal containers for GPU/long pipelines.
5. Auditor
   • Logs decisions/events to Redis + S3 for reproducibility.

Decision PolicyCopy Anchor Link

Signals scored by the Router:

• Duration forecast: > soft budget → heavy/continuation
• Capability needs: GPU, long-context, tools → heavy
• Safety risk: high → heavy proctor or human-in-loop
• Latency target: interactive → prefer local
• Cost ceiling: avoid overage
• Reliability: select environment with better quotas
• Data governance: PII/export constraints may force local
