Release notes

Current payload:

Experts: integer L1-ball trellis codes (K=1.5, V=8; book: packed/experts/codebook.safetensors) + wave_gamma per-wavefront scales + continuous fp16 su/sv side-streams. Expert files carry NO Wscale — sv is the complete scale (decode with wscale=None); wave_gamma applies in rotated space before the su/sv Hadamards.
Spine: 64-level integer lattice in the K=4 trellis. Head: int5-g64. Embedding: int4 + exact-overwrite exception list.
Ship gate: decode.py-primitive reconstruction == the served checkpoint (bf16 rounding, layers 0/20/39 x 4 experts x 3 projs).
Full measured board and retention table: see BOARD.md. Expert payload 6.207 GB.
