highReviewed `src/math/libm_math/support/hex_float.rs`, which implements hex-float parsing/formatting helpers plus unit tests for `f16`/`f32`/`f64`/`f128` conversions. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network or exfiltration calls, credential or secret access, dynamic code loading, obfuscation/packing, or persistence behavior; the only notable runtime stubs are explicit `unimplemented!()` branches gated on `compiler-builtins` and consistent with the file's purpose.
