Today that state is typically scattered across Postgres, Redis, Pinecone, and other systems with no consistent snapshot boundary. The post argues for consolidating all agent state into a single object storage bucket, enabling copy-on-write forking so you can branch an agent's entire world before risky actions, parallel experiments, or eval runs. Using Tigris and Daytona as concrete examples, it walks through a practical shim: fork the bucket before each sandbox run, mount or access the fork with scoped credentials, then promote or discard after validation. This gives fleet-scale per-run isolation at near-zero cost since forks are metadata, not byte copies. ## Full article daily.dev links to this article rather than hosting it.
