An assistant that forgets everything between chats can’t be trusted with anything ongoing.

I run a fleet of AI coding agents in my homelab, and for a while they all had the same flaw: every session, they forgot everything.

Context windows are big now, but they’re not forever, and the moment a long session compacts or a new one starts, all that context is gone.
