(I work on uv.)

Can you say more? uv should always tell you if a wheel build fails, unless the build backend (which uv doesn’t control, unless you use uv’s own backend) decides to silently ignore a wheel build. This would be a bug in any given build backend IMO.

This is an unfortunate complexity in Python packaging: something like `uv build` can dispatch a wheel build for you, but the actual code that gets run as part of that build is often third-party build backend code that uv itself has little to no control over.

It happened almost 6 months ago, trying to build https://github.com/remsky/Kokoro-FastAPI with uv. From what I can still infer from the dependency list & my shell history, the problematic dep had been pyopenjtalk. After building & installing this dep with pip, I was able to continue to use uv.
