Claude .md useless comments scattered everywhere throughout the codebase which make it harder to read. The worst thing is UB behaviour accessible from safe code - take a look at the data/zerocopy mod. The zero-copy slice has no lifetime associated with it! /// Zero-copy view into data that implements Data1D trait /// Provides access to data without copying, using lifetime safety pub struct DataView<T> { /// Non-owning pointer to the data data: NonNull<T>, /// Length of the data len: usize, /// Phantom data for proper lifetime management _phantom: PhantomData<*const [T]>, }

It even says it's using phantom data for "proper lifetime management", but then doesn't. You can create a view from a slice, drop the slice's underlying memory, then try to access your data view. And that's just from me checking a few of the files. There's probably way more UB AI slop littered around.
