Decoupled Brain and Hand: Architecture Design and Boundary Governance for Enterprise Agent Platforms
Moving single-node agents into enterprise multi-tenant environments requires crossing four chasms: host corruption, credential leakage, gateway timeouts, and asset ownership. The enterprise agent platform architecture decouples brain and hand: a high-availability control plane (Harness) owns the reasoning loop and state machine, while an elastic sandbox pool leases isolated compute on demand. This article explains the four system boundaries of enterprise agent platforms: control-plane and execution decoupling, secret exclusion with egress proxies, append-only incremental state, and team workspaces as persistent assets.
