Change and mathematical scope

NO VERIFIED GAIN. Three exact bank separators exclude the fixed chart-431 owned provider fork and product-return proposals on exact #7481 at 89eaa9d8cae37c1540de98f2d29a3abaabb96a2b.

• Before ADD34568, x2=1 kills all five surviving chart-431 rows, including old375, while the observer needs −1.
• Before MOVE34566, the same probe kills all 623 live chart-3 source rows, including the existing paid carrier1348, while old1513 at ADD34527 is 1.
• Before MOVE35452, the eight-coordinate probe kills all 22 live chart-243 rows and the retained product, while historical old1137 and the required return are both −1/2.

Each proposed rank-one/rank-two fusion has an optimistic gross of about 0.11809207775534 raw before ancillary costs. One new rank-one call per copy costs 17 raw. No literal edit survived. κ is unchanged.

Task and overlap

Refine the fixed-paid chart-local repair scope of the complex supplier on canonical base e54523517d0f03e58352e647c403a5af3e525a57, with signed #7113 at 07a76c5e2738882c0cb322278e56f6cae3c9885d. #7308 checks original-destination banks and #7392 checks different fixed-itinerary dirty loans. This package checks three named cuts on the same chart431 provider and return chain. The two separate CI prerequisites reuse #7257.

Validation

From a clean POSIX checkout with CPython 3.12:

python3.12 -I -B research/p104-chart431-owned-transport-bounds/replay.py

The wrapper authenticates the inputs, regenerates six receipts, and checks the directed price and independent forward separators. The control that drops the historical operand ADD changes the old return to zero on the stronger probe. Direct and registered replay, commit modes/source-history checks, read-only Git-free export and 27 onboarding tests passed locally. Physical and complete multiplier replay did not run because the necessary source or restoration conditions failed.

Credit

#7481, #7480 and #7334 supply the native lineage, #7113 the signed caller, #7003 the old-version source precedent, #7308 and #7392 the related bank methods, and #7482/#7298 the coefficient and directed-price tools. #7498 supplies public copies of the exact inputs. OpenAI Codex and subagents materially assisted. Review and merge remain with maintainers.

Open next questions

Earlier encoding, different banks and altered paid routes remain open. Require a named exact source and its independent dirty return before testing another carrier.
