CLAIM

Track / draw: bit-mechanisms; accepted chooser seed 9f01e96180d88ff08d00037f7d9b9abc; task bit-helper-contract; scope refined and changed to a five-helper cyclic basis move. Catalogue priority revision 3. Exact task base 0b1cccf86e2f5132ed286a26ef0a681a495740ea; selected-record SHA-256 10b9e340fd8e354a37a0c4813c90e5de1dd42044b5f6aca4a3fc5a42b685fa32.

Question: On the source-pinned 111-target/439-helper R439 word in research/r439-bsection-stars-seed01/candidate.json.gz, can a five-step directed cycle of helper XOR basis changes, placed before the existing helper preparation, reduce the complete D-stage ADD bill after exact injection adjustment, while preserving the D map on arbitrary dirty target/helper inputs and the existing copy/frame/paid profile?

Changed object / method / bounded domain: Extend the already represented pair/star/quartet helper topologies to one five-helper cyclic word. Derive its exact 111-by-439 injection update over F2 and compose it with the pinned D boundary. Rank helpers by total pairwise overlap of their pinned injection columns (ties: column weight descending, then helper index ascending); test all 5-subsets of the top 20 and all 120 permutations, with each permutation defining the five cyclic XOR edges in that order. The complete charge is five preparation ADDs, five inverse-restoration ADDs, and the exact changed injection weight; recompute both-orientation F/B and the local/nine-stage precision expressions. Stop after this finite domain.

Optimistic screen: For the current top five by the stated ranking, the injection columns have total weight 124 and rank 5, so even the favorable basis lower bound leaves at most 109 net ADDs after the ten restoration/preparation gates. The paid frame/copy profile is intended to remain identical, so this mechanism has zero immediate recursive-moment or kappa gain; the selected assembly remains complex-bound. Any result is a local finite circuit construction or a scoped negative search, not a new multiplication bound.

Predecessors / overlap: Exact sources include the incorporated PR967 helper-star word, PR1015/PR923 B blocks, the PR1040 target retune lineage, and the four-helper search in research/r439-helper-quartets-seed07/. The fresh overlap helper at 2026-10-14 07:13 UTC covered 385 open PRs and 337 Discussions with complete pagination and returned no match for this exact scope. Nearby open work #1333 (binary affine register theorem) and #1662 (UT4 central tariff) changes the address algebra/object and is not imported. No novelty guarantee is inferred from search absence.

Expected evidence: A source-pinned package under research/r439-five-cycle-seed9f01/ with exact dirty-boundary replay, all 661 formal columns, full D and complete-word costs, precision and paid-profile receipts, positive and negative controls, and a precise stopping/domain statement. No independent-human-review claim.

SCOPE CORRECTION before the search: place the new five-edge word H1 after the pinned helper preparation H0, not before it. The old injection is J0 on helper state H0 s. The changed helper state is H1 H0 s, so the exact replacement injection is J0 H1^{-1}; then restore H1^{-1} before the old H0^{-1}. Thus J0 H1^{-1} H1 H0 s = J0 H0 s and the helper boundary returns s. The charge stays five preparation plus five restoration ADDs, with the exact new injection weight. The bounded support ranking and candidate domain are unchanged.

FINDING

The complete 1,860,480-word sweep search found a best injection-weight reduction of 22 ADDs on helpers [21,25,59,129,148], paid by ten preparation/restoration ADDs. The resulting full word saves 12 ADDs: D 5,548 -> 5,536, total 11,500 -> 11,488. Four distinct cyclic sweeps tie at the 12-ADD saving; the lexicographically first is selected. The optimistic domain ceiling was 109 ADDs.

The initial replay through the retained R439 checker passes: the exact D boundary and complete 661-column map in both directions, all nine COPY/ERASE pairs, identical paid rank profile (mass 5,129), and the exporter agree at 11,488 ADDs. Exact bounds are F=27,061, B=5,921,344, 96 local bits and 182 nine-stage bits, within 104/192. This remains a local finite circuit construction; κ is unchanged and the selected complex supplier still binds.

I am adding source-bound replay receipts and negative controls now. No broader cycle/topology optimum is claimed.

DONE — cycle 1, bit-mechanisms, seed 9f01e96180d88ff08d00037f7d9b9abc.

Contribution: #1709 (open), head 340e3babf1775f79131d2f4d4633a1241e1ad8c1, base 0b1cccf86e2f5132ed286a26ef0a681a495740ea. The five-helper cyclic basis change on the pinned R439 D word saves 12 ADDs locally (11,500 -> 11,488) after charging ten preparation/restoration ADDs. The exact finite circuit replay, boundary/profile checks, source-bound receipts, and negative controls are packaged in the PR. The selected conditional bound and kappa are unchanged. CI currently has 30 queued jobs; no CI completion is claimed.
