Eliminating Hallucinations with Deterministic State Machines: Zero Probabilistic Error in Financial Ledgers

If you ask an AI researcher how to solve hallucinations, they suggest more training data or larger models. If you ask an enterprise systems engineer, they will tell you the truth: you solve hallucinations by stripping the model of unconstrained authority.

1. Generative Text vs. Deterministic State

A generative model can suggest a transaction, but it cannot commit it. In our architecture, autonomous agents submit proposed state changes to a deterministic Finite State Machine (FSM) that verifies strict mathematical constraints.

$ scarpian-fsm transition --event invoice_matched --payload state.json
[EVALUATION] State: PENDING_MATCH -> Transition: READY_FOR_SETTLEMENT
[CONSTRAINT CHECK] Total debits == Total credits: TRUE
[CONSTRAINT CHECK] Vendor tax ID matches IRS database: TRUE
[RESULT] State transition PERMITTED. Non-conforming actions mathematically blocked.

2. The Mathematical Quarantine

If an agent produces an output that violates state invariants, the transition is rejected automatically, quarantined for human audit, and the agent's context is reset.
