33 CPU-only tests: FP8 block-wise/per-channel round-trips, NVFP4
round-trips (direct + reciprocal scales, native vs manual unpack
agreement), scheme detection incl. ModelOpt MIXED_PRECISION, surgery
guard raises, and tiny synthetic FP8/NVFP4 GPT-2 checkpoints through
load_model end-to-end. Full suite: 870 passed (8 failures pre-exist on
main, verified against pristine checkout).
docs/theory_journal.md Appendices E-E2: engineering log of the 12
findings from implementation and real-checkpoint validation (nibble
order conventions, mixed-precision layouts, the 96GB OOM and the
chunked-unpack fix, transformers 5.x drift shims, Omni wrapper unwrap).
