Artifacts: versioned storage that speaks Git

This post introduces Artifacts, a new primitive: a distributed, versioned filesystem built for agents that speaks Git. It allows programmatic creation of Git repositories for agents, sandboxes, and other compute paradigms, with REST API and native Workers API access. It also introduces ArtifactFS, a filesystem driver for mounting large Git repos quickly by hydrating file contents on the fly, ideal for agents and sandboxes with critical startup times. Artifacts is built on Durable Objects and a custom Git server implementation in Zig compiled to Wasm.
