# Optimization benchmarks and case studies

> Canonical page: https://codevetter.com/benchmark/optimization

These dated local trials have separate evidence boundaries rather than one blended headline. Each case study names the exact flow, revision, source candidate, patch cost, correctness scope, repeated measurement, decision, availability, and limitations.

- [Anime List](https://codevetter.com/benchmark/optimization/anime-list) — retained: A two-file import-boundary change materially reduced one local Vite navigation, while a separate production build showed almost no shipped-bundle movement.
- [Free AI](https://codevetter.com/benchmark/optimization/free-ai) — confirmed: A one-pass model-selection loop removed an intermediate array and improved every tested registry size without growing the patch.
- [Starboard](https://codevetter.com/benchmark/optimization/starboard) — rejected: A plausible incremental token scanner passed focused correctness but ran slower, so CodeVetter rejected it and restored the original code.

A rejected experiment remains visible. Historical research capability is labeled separately from the compact runtime path currently shipped in CodeVetter.
