The independent owned-COPY/shared-map proposal attempted to reduce the eight center inputs in the actual round-three word. This package proves that each high contact already contains eight independent vectors from fixed main entrances, even after every native warp relation and every helper boundary constraint is removed. Keeping the opposite center chart at zero therefore leaves paid center rank mass at least 64. The source attains the bound. No higher κ or whole-profile optimum is claimed.

This extends the high-contact part of Matarener's #5060 to a newer source and a larger retiming domain. #5060's complete nested owned-wire floor with fixed native/helper boundaries remains prior work; this PR does not extend that whole-wire conclusion to the larger domain. Cao Yifan's round-three source, Cinna Davis's supplier/controller lineage, Dugongue and the retained authors are credited. Frozen source bytes stay unchanged.

The standalone exact proof artifact contains 128 main-entrance paths and 2204 chronological links across both orientations. No relation crosses any of the 240 native events per orientation. It reconstructs the complete original paid/helper histogram, verifies the owned macro boundaries and checks 144 corruption, rank-seven-hyperplane and warp-cut controls. Standard library only; no solver or predecessor executable import.

Validation:

• Registered normal and optimized Python replays pass.
• Package metadata/source pins, deterministic witness regeneration, commit-byte preflight and diff whitespace checks pass.
• The optional source-history preflight rejects this intentionally shallow checkout before checking ancestry; no pass is claimed for it. All scientific live inputs are retained on canonical main at the package base, which is the publication's direct parent. Hosted CI is separate.

Open next questions cover moving both sides of a center, changed scalar chronology and nonmonotone paid itineraries, with full paid/helper invoices and native/ownership/compiler obligations. Canonical investigation: #4611 (comment) . Main refreshed before submission at 20a1e31; priority 7 and selected conditional κ=.00302015 unchanged. Overlap snapshot covers 316 open PRs, 4285 discussion records and all 6884 base notes; arbitrary diffs and unpublished work remain outside that coverage.
