topic: codec
20 modules sharing the codec name family (derived from the tree's prefix discipline).
The 'codec' topic family in the Nishi sovereign ecosystem focuses on evaluating and benchmarking different compression algorithms within a self-contained, same-corpus framework. Modules like _codec_bench compare codec performance directly without external tools, while _codec_bench2 tests Nishi-PNG against real PNG filters using shared entropy stages. _codec_real_med isolates predictor behavior across a representative corpus, ensuring consistent evaluation. These modules collectively support a rigorous, sovereign-grade assessment of codec capabilities and efficiency.
