Function crc32_ieee 

pub fn crc32_ieee(bytes: &[u8]) -> u32

The IEEE (reflected, polynomial 0xEDB8_8320) CRC-32 of bytes.

The standard zlib.crc32: its check value over b"123456789" is 0xCBF4_3926, pinned by test. Used only for the storage-free Hyperband bracket assignment — never as a cryptographic hash.
