Deterministic Failure
Canonical definition (Arco Lexicon)
A failure mode that is predictable, fully logged, and recoverable by design — the architectural standard Arco engineers into every autonomous system so that when the system breaks, it breaks safely.
Extended Definition
Deterministic Failure is the opposite of a black box failure. In a non-deterministic system, a failure produces damage and then silence — the operator discovers the failure after the fact, reconstructs what happened through incomplete logs and human testimony, and hopes to prevent recurrence through vigilance. In a deterministic system, failure follows a defined protocol: the workflow halts at the point of deviation, the full execution context is logged — the specific logic gate, the input data, the confidence score, the deviation measurement — the recovery mechanism is triggered automatically, and the Steward is notified with enough information to update the architecture before the workflow resumes.
