Canonical input
State begins from declared authoritative inputs, so the starting point is evidence rather than a convenient assumption.
Solutions
State should be reproducible, not persuasive.
Deterministic State Engines (DSE) calculate operational state under versioned rules, explicit time basis and fail-closed contradiction handling.
Deterministic State Engines
When the same authoritative inputs and versioned rules must resolve to the same state every time, persuasion is not enough. DSE preserves canonical inputs, explicit time basis and fail-closed contradictions so state can be replayed and defended, not argued.
Versioned rules
Configuration changes are explicit and replayable, so a past result can be reproduced under the rules that produced it.
Fail closed
Missing or contradictory required truth produces HOLD or non-action instead of confident fiction.
Projection
Consumers render engine output without cloning the math, so financial and operational truth has one calculation authority.
Current Evidence
Same inputs, rules, build and time basis reproduce the same state.
Contradiction resolves to HOLD / non-action rather than inferred state.
AIE (telecom activation) and BFIE (financial and evidentiary) sit under one deterministic parent.
Proof
Engine claims are testable.
DSE locks replayability, explicit lane boundaries and fail-closed handling: missing or contradictory required truth produces HOLD rather than an invented result. AIE has completed three twenty-million-evaluation test runs sealed for independent verification.
