Deterministic Loop

Canonical definition (Arco Lexicon)

A revenue loop in which the core transaction steps follow a fixed, encodable sequence — the architectural precondition for autonomous operation and Arco's second structural indicator of a breakable market.

Extended Definition​

A Deterministic Loop is a revenue loop that can be fully mapped as a decision tree and encoded as logic without requiring human judgment at the evaluation points. Every step in the loop produces an output that the next step can accept as a deterministic input. When an exception occurs, the exception itself is classifiable — it belongs to a known category that has a defined handling protocol, or it escalates to a human Steward with sufficient context for resolution. There are no steps that require a human to interpret an ambiguous situation before the loop can continue.

The Deterministic Loop is distinct from the Revenue Loop. The Revenue Loop describes the economic sequence that generates a transaction — the steps from initial trigger to completed transaction and payment. A Deterministic Loop is the architectural evaluation of whether that sequence is encodable. A market can have a high-frequency Revenue Loop that is nonetheless not deterministic — if the evaluation step at the end of the sequence requires subjective judgment, the loop fails the Deterministic Loop test regardless of how frequently it repeats.
