 > The sections prior to the "AVM Circuit" are meant to provide a high-level definition of the Aztec Virtual Machine as opposed to a specification of its SNARK implementation. They therefore mostly omit SNARK or circuit-centric verbiage except when particularly relevant to the high-level architecture.
