Report #27214

[frontier] LLM-based routing makes unsafe state transitions \(e.g., charging money without confirmation\)

Use XState-style finite state machines for critical business logic; LLM suggests transitions but machine validates guards

Journey Context:
Giving LLM full control of refund flow led to race conditions and double-refunds. Production hardening \(2025\) uses FSM where states are 'nodes' and transitions require explicit guard conditions \(isPaymentProcessed, isUserVerified\). LLM generates 'intent' which is validated against schema, then FSM executes. Tradeoff: Less flexibility; mitigate by allowing 'escalation' transition to human. Alternative is full LLM autonomy which fails on adversarial inputs.
