The apex brick of the scalar layer: for any 64 bytes (the opaque SHA-512 digest), [from_bytes_wide bytes] = (LE 512-bit value) mod l, with canonical 52-bit-bounded output. Composition: bytes_unpack_spec (8x8 loops) -> split_words_lo/hi_spec (exact div/mod per limb, disjoint ORs as additions) -> wide_split_telescope (isolated omega) -> montgomery_mul by R and RR (R cancels as a unit, RR restores it) -> the canonical add. The two kernel-capacity walls found and crossed en route (control repo FAILURES.md updated): - a montgomery_mul inside any walk motive replays its 400-line body at every kernel step (fix: named prefix functions in the pinned source); - straight-line IndexMut closure chains make kernel defeq exponential in depth (fix: struct-literal construction - the split halves now build Scalar52([...]) directly). Full certificate: 77 s kernel-inclusive. Regenerated gen (sources factor from_bytes_wide -> from_bytes_wide_parts -> split_words_lo/hi; documented pure refactors, cargo-checked). check-scalar.sh: 13 proof files, 13 kernel audits, all exactly [propext, Classical.choice, Quot.sound]. Button pressed fresh: green. |
