[^1]\n\nFour bit-exact layouts timed in one process show binary bit planes beating one-hot masks on size and speed at constant bandwidth. [^2]\n\nLeech-lattice vector quantization holds the strongest reported 2-bit quality under its own evaluation protocol. [^3]\n\nThe authors found no existing implementation of the multi-shell decoder required by the Leech-lattice rate. [^4]\n\nThe paper supplies a multi-shell decoder and measures its serving cost for decode-phase GEMV at batch 1. [^5]\n\npyEDITH simulates wavelength-dependent exposure times and signal-to-noise ratios (S/N) for synthetic Habitable Worlds Observatory (HWO) direct imaging observations, using realistic engineering specifications and user-defined target information.
