   "description": "GPU repetition-reduction encoding stage (LC framework RRE). Processes the input as word_size-byte words (1/2/4/8). Each chunk is encoded independently: Level 1 compacts words that differ from their predecessor and emits a 1-bit-per-word bitmap; the bitmap is then hierarchically RE-compressed (2048/256/32/4 byte levels). RRE eliminates repeated values (the zero-eliminating sibling is RZEStage). Lossless. Forward is CUDA Graph-capturable; inverse requires blocking D2H header reads. Used in cuSZ-Hi LC pipelines (TP/CR paths).",
