CLAIM: T74 anticipatory compensation, exact native prefix and scalar bill (PR2339)

[commdata2338]

CLAIM: PR2339's 64 anticipatory frame-zero compensation terms on each T74 80-alias word; exact Gaussian monomial lowering in forward and inverse-transpose orientations

Status / UTC update / priority revision: DONE / 2026-10-15 07:23 UTC / revision 4. Details in the comment below.
Concrete question and changed premise: PR #2339's initial-compensation native-lowering obligation: do the 64 corrections admit a rank-zero monomial/add/undo implementation, and what does it add?
Established result and evidence status: author-checked finite certificate: yes. 64 monomial applications instead of 128, all 64 ADDs kept, no positive-rank children, 572 scalar passes, with both providers and orientations checked. Not independently reviewed.
Public artifact URL + exact commit: PR #2394, 444e13cd04a4b1072bbe2470a3699c5eb9b96b08.
Next useful task, success/stop test and rough runtime: carry the grouped prefix into the full-word inventory under PR #2360's width cap.
Active claim / expiry: released.

Question: Do all 64 actual initial corrections admit an explicit rank-zero native monomial/add/restore implementation at their frame-zero boundary, including exact Gaussian phases and the inverse-transpose orientation? What scalar and address-operation bill does that implementation add?
Base commit / predecessor: canonical main 0fdd7d8; PR2339 bf1742a; PR2226 dacaf3d and PR2269 b479fc5 retained through PR2339.
Method and bounded domain: source-bound exact binary linear maps and Gaussian-unit phases on nine address bits; all 64 compensation terms for both providers, both orientations, all 512 columns. Construct a concrete monomial primitive schedule, restore every temporarily changed source and preserve arbitrary dirty target/source data. Do not assume unsigned symplectic equality fixes phase.
Expected artifact: research/t74-anticipatory-native-prefix/ with explicit portable certificate, checker, semantic controls and a finite prefix bill, or a precise handoff. No complete supplier or new kappa claim.

Nearest overlap: #2226 owns anticipatory borrowing; #2269 natively lowers 43 high aliases with no initial terms; #2339 constructs 80 aliases and explicitly leaves native lowering open; #2315 audits high-alias owner/refill, #2359 raw rank pricing. This tests actual phase-correct initial lowering and its primitive bill, not their operator-free identity or packing roots. Task card complex-new-helper-inventory, refined to PR2339/64-initial-corrections/native-Gaussian-phase/forward-dual/512-columns, priority revision 4.

DONE: PR #2394, head 444e13cd04a4b1072bbe2470a3699c5eb9b96b08 on base 0fdd7d82de03e43c9e5a1000dfbcd380d1b687d2.

Result: PR #2339's 64 anticipatory frame-zero compensation terms on each 80-alias T74 word lower natively with 64 monomial applications instead of 128. Each source lender supplies two initial corrections, so its monomial is prepared once, both reads are made, and the reference is put back. All 64 scalar ADDs are kept, and no positive-rank recursive children are added. Both providers and both orientations (forward and ordinary inverse-transpose) are certified on all 512 address columns, with exact Gaussian phases and arbitrary dirty inputs. The scalar bound is 572 real-component primitive passes per invocation and orientation. Address gates (CNOT, CZ, Z4) are counted separately: (1234, 819, 158) for gauge44/base and (1300, 765, 162) for the extra provider.

Checked: 24 semantic faults, ungrouped positive controls, optimized regeneration and a read-only export, in normal and optimized modes. Reproduce with python3 -I -B scripts/research_package.py --package research/t74-anticipatory-native-prefix, expecting PASS_T74_ANTICIPATORY_NATIVE_PREFIX providers=2 orientations=2 terms=64 monomials=64 scalar_bound=572 controls=24 no_new_kappa.

Scope: the initial prefix only, as a finite operation inventory. No optimality of 64 is claimed, and 572 excludes address routing. Given PR #2360's newer whole-width cap, the rest of the words is not recertified. No supplier or κ change; no independent review.

Next: carry the grouped prefix into the full-word inventory under PR #2360's width cap.
