Change and mathematical scope

Fix role 1123 at pre-event cut 41740 on chart 242 of exact #7334. A stationary owned difference buffer may inject into any original cocharted public role through the final cut. The projected guarded response has rank 19 and lacks the pivot direction. Two literal chronology walks reduce all 328,333 cut-role pairs to the same twenty maximal columns and agree that the twelve later contacts are public egresses.

The same dual excludes the funded variant. It grants one rank-one terminal exit 245→127 acting by a nonzero normalized scalar on the successor carrying logical pivot 1123 after the fixed old suffix, with all other coordinates and guards preserved. It enlarges the correction cohort to 616 roles. The dual still meets that cohort only at role 1123, so reweighting its pivot coefficient preserves separation. Both scopes are exhausted.

NO VERIFIED GAIN. The strongest independently reproduced comparator remains #7334 at aaeec8c0acf01e99a5f331ef363a698d9c084ace. The fixed-paid 4+4 optimistic upper is 0.34159729371268563 raw, rounded upward. The funded 4+5 quote charges P1+17 and changes T4+17, T5+17 and T8−17, with upper 0.18708348264968764 raw rounded upward. Neither construction is feasible within its tested scope.

Task and overlap

This refines the chart-242 endpoint scope of #7363 and #7374 from static banks to a stationary buffer over the full literal history, then tests the distinct funded-exit cohort. The paid fixed-route scope and its one funded relaxation are frozen in the package task and source receipts. Signed caller #7113 is pinned at 07a76c5e2738882c0cb322278e56f6cae3c9885d. Canonical main was e54523517d0f03e58352e647c403a5af3e525a57 at the pre-submit refresh.

Validation

Run from a clean checkout with CPython 3.12 and assertions enabled.

python3.12 -I -B research/p104-stationary-chart242-history-bound/replay.py

The clean Git-free replay regenerates nine receipts and rejects four altered dependencies. It checks both full chronology walks, the exact guarded separation, and the funded price and dual transfer. The funded stage uses the authenticated earlier columns. A physical exit and complete candidate replay were unnecessary for the exclusion. The research commit adds one package and uses the two existing #7257 CI fixes. Those fixes address the historical selected replay gap documented in #7371. The selected record is unchanged.

Credit

#7334 and #7113 supply the word and signed caller, #7338 and #7298 the invoice and tariff, and #7363 the exact pure prefix and geometry. #7374 closes the residual static stock. #7156, #7148 and #7244 supply temporal and chart-245 precedents. #7355 supplies the rational row engine. #7161 supplies the funded exit for a different helper, and #7362 the larger cohort and rank stock. OpenAI Codex and subagents materially assisted.

Open next questions

Other retirements, new chart-242 response generators, changed guards or changed paid routes require a separate priced test. Review and merge are left to the maintainers.
