Coder stages

Stage	Description
HuffmanStage	GPU Huffman entropy coding (cuSZ port)
ANSStage	GPU rANS entropy coding (dietGPU, byte-level)
GPULZStage	GPU LZSS (LZ77 + flag-bitmap) lossless compression (GPULZ)
RLEStage	Run-length encoding
RZEStage	Zero-word bitmap reducer with recursive bitmap compression (LC component)
RREStage	Repeated-word bitmap reducer with recursive bitmap compression (LC component)
RAREStage	Adaptive top-bit matching generalization of RRE (LC component)
RAZEStage	Adaptive leading-zero-bit generalization of RZE (LC component)
CLOGStage	Per-subchunk leading-zero compression and adaptive bit packing (LC framework lossless component)
HCLOGStage	CLOG bit packing with per-subchunk TCMS selection (LC framework lossless component)
BitpackStage	Dense bit-packing of fixed-width integers
AdaptiveBitpackStage	Per-block adaptive fixed-rate bit-plane coding (cuSZp plain mode)
Speck2DStage	GPU-parallel "wavefront" SPECK-like coder (2-D), decode-parallel format
OutlierCorrectStage	Sparse exact outlier correction — turns a coefficient-domain quantization bound into a guaranteed reconstructed-domain pointwise bound, transform-agnostic
