Change and mathematical scope

NO VERIFIED GAIN. The exact comparator is #7334 at aaeec8c0acf01e99a5f331ef363a698d9c084ace with signed #7113 at 07a76c5e2738882c0cb322278e56f6cae3c9885d.

The paid pair for owned role 1531 spans 41996/44242 and contains two incoming ADDs. Their signed aggregate is −2 times the original role-1291 row plus −1 times the original role-732 row. Both engines agree on all 219 nonzero coordinates. At the two original endpoint cuts on charts 594 and 534, all live cocharted donor rows and the pre-first owner diagonal vanish at input coordinate 244. The aggregate is −1/2 there. This excludes both fixed banks even with arbitrary rational combinations and existing owned donors. No selected key remains unresolved.

The direct rank-five route would change the complete paid histogram by P1−17, P4−17 and P5+17 across 17 copies. The optimistic one-edit saving is at most 0.154513811062998 raw. Both placements spend the same anchors. No edit survives.

Task and overlap

This is an owned p104-side-correction scope. #7354 inventories the lifetime, and #7355 covers the adjacent later sole-ADD pair. The released role-1531 scope includes the same anchors under a different producer and recovery contract. The research commit adds only research/p104-owned-two-write-aggregate-bound/. The two existing #7257 commits address the canonical CI navigation mismatch documented in #7371.

Validation

Use CPython 3.12 from a clean checkout.

python3.12 -I -B research/p104-owned-two-write-aggregate-bound/replay.py

The Git-free replay authenticates the #7354 inventory, #7362 price manifest, #7334 word and #7355 engines. It regenerates the directed price, both bank receipts and their agreement. Four altered-input controls reject. Add --out fresh-directory to retain the receipts. Registered-package, source-history, navigation and export checks passed.

Credit and open next questions

#7334 and #7113 supply the exact native word and signed caller. #7307 supplies earlier owned chronology, #7354 the owned inventory and #7355 both span engines. #7362 and #7338 supply the rank stock and admitted receipt, and #7298 the directed tariff. Campaign Round 112 supplies the analogous public aggregate method. OpenAI Codex and subagents materially assisted.

A new donor path or changed producer would need a complete price before signed support. Review and merge are left to the maintainers.
