# j2k-codec-math
`j2k-codec-math` is the workspace-owned source of truth for codec constants,
generated backend fragments, and allocation-free helper algorithms that must
remain byte- or numerically-equivalent across CPU, CUDA-Oxide, and Metal
backends.
The crate is `no_std` and intentionally contains no allocation, I/O, backend
dispatch, or kernel-launch policy. Helpers such as canonical Huffman derivation
perform validation and ordinary control flow.
