arXiv 2608.06640 covers a brownfield C++ codebase with per-line production observability, April 2025 to April 2026. AI code showed higher interface and coupling burdens, copy and allocation overhead, and a preference for explicit loops over optimized standard APIs, translating into more review effort and a measured 5–8% compute increase. The mitigation is the rare part: targeted, taxonomy-informed feedback to the models produced an 11.1% reduction in targeted static analysis warnings. This is the first study I've seen that costs out AI-generated code in cloud dollars rather than vibes.
