Memory is where the harness stops being a wrapper and becomes an ownership layer. Once it controls what gets remembered, retrieved, compressed, and acted on, it starts shaping the agent’s judgment, not just its UX. That means closed harnesses don’t just create product lock-in. They create learning-loop lock-in. Model switching will get cheap. Migrating accumulated context, behavior, and institutional memory won’t. That’s why the moat is moving up the stack.
