Agent Substrate implements a virtual actor model on Kubernetes. The core idea: decouple long-lived stateful actors from physical pods so that thousands of suspended actors can share a small pool of warm worker pods. An actor's full memory and filesystem state is checkpointed to object storage (GCS/S3) when idle, and restored onto any available worker pod in milliseconds when traffic arrives.
Here's how each component contributes.
