Partition Scores Are Not System Scores: Deployment-Fidelity Gaps in Decomposed Algorithm Selection
The deployment-fidelity gap G(R) is defined as the difference between partition-level and deployable end-to-end utility and derive two accounting consequences: a per-instance margin-regret stability condition that tells us when a partition-time family choice is deployment-optimal, and a sharp partition-only identificat...
