UPSTREAM TITLE: Forward-Deployed Engineering: The Four-Layer Agent Stack
SHORT SUMMARY: ibl.ai defines a production FDE engagement around four customer-owned layers: repeatable environment provisioning, domain evaluation, governed agent deployment, and simulation. Its ownership checklist argues that durable forward-deployed work is distinguished from support by portable source, infrastructure, evaluations, controls, and runbooks that remain with the customer.
