ApertoMemory EMILIA Protocol, Inc. Encrypted and signed memory objects can establish source integrity, authorship, and read-time trust without establishing which exact bytes a memory adapter selected and delivered to a downstream AI system. This document specifies a provider-neutral signed Memory Projection Record. The record commits to the recall request and selection policy, the read-time keyring snapshot, the ordered source objects and exact context fragments delivered, the complete projection bytes, and summarized exclusions. It deliberately does not claim that a model received, used, or weighted the projection, that an action was authorized, or that an outcome occurred. ApertoMemory is one source profile; other memory formats can use the same projection boundary.
