The Artifact Availability Layer

This technical note introduces the Artifact Availability Layer — a dedicated infrastructure layer designed to preserveartifact graphs, the structure of completed computational work, across distributed agent environments. The note draws a fundamental distinction: traditional infrastructure preserves data. Autonomous computational systems must preserve computational work. Artifacts produced by computation are not merely stored outputs — they are infrastructure objects that form dependency networks. Without durable artifacts, completed computational work vanishes when systems terminate. Just as filesystems enabled document persistence and databases enabled application state preservation, the ArtifactAvailability Layer represents the infrastructure evolution required for agent ecosystems that continuously generatederived knowledge and synthesized outputs across distributed workflows. The layer maintains artifact identity,derivation relationships, and accessibility across distributed computational environments as first-class concerns. This is Technical Note 05 of the Agent Artifact Availability (AAA) Framework series.
