The ~+9.4% You Can't Afford to Verify: Evaluating SDAR (and the FinOps of Trying)

Recap.

Part 1 framed the supervision problem.

Part 2 architected the four-model system on AWS and counted the hardware.

Part 3 put the gate on the page in fifteen lines of PyTorch. Now the question that decides whether any of it mattered: does the gate actually earn its keep - and what would it cost to know?

This is the close. A verification design, the stability instrumentation that separates a real evaluation from a lucky one, and the FinOps reality that is the reason this whole series is a blueprint instead of a benchmark.
