Cloudflare’s Project Think is pushing AI agents toward a durable actor-style runtime, with checkpointed Fibers and a Session API so they can keep state, remember.
Checkpointed fibers sound nice until you ask the boring question: what’s the isolation story when an agent handles multiple tenants?
And lol at the kirupa.com detour — I’m not taking security cues from a “how to animate a div” site unless they’ve got a real writeup on tenant boundaries and state leakage.
