A cloud-free serve path is provable end to end; every layer moved from Ceded to Retained is a decision you now own and a system you now operate.
The control plane held where patterns were owned and encoded, and failed where the model became the author of correctness. The question is who may author the patterns and done-criteria.
About 5% of tasks benefit from same-tier repair; the control point is the deterministic validator plus escalation policy, not the loop.
For a custom model you own, cloud token pricing disappears and becomes a rented floor; against a floor the owned box wins, and the managed path takes the weights.
The managed data plane is cheap and fast; the cost it hides is the chunking judgment it takes from you. Borrow the plumbing, keep your own chunking.
