[frontier] How to enforce deterministic state transitions in LLM agents without code

Use OpenAI Structured Outputs \(JSON Schema\) to constrain LLM responses to specific state machine transitions, treating the LLM as a control plane that emits valid state transitions only.

Journey Context:
Hardcoding agent logic limits flexibility; freeform LLM calls lack guarantees. Structured Outputs force the LLM to choose from valid next states \(e.g., analyze → validate or reject\), effectively creating a declarative control plane with compile-time guarantees. Eliminates invalid state transitions that plague dict-based agent frameworks.
