Exact identities and proved scoped implications; no numerical certificate or new window. API, the uniform floor, G2 and RH remain open.
The actual arithmetic operator fails local open-set unique continuation, including both parities for a > log 2 and after finite source constraints. These witnesses are not full-window nullvectors. The full semigroup fails ordinary-cone positivity preservation; no negative diagonal Weil direction follows.
Prime-free exterior-cell uniqueness and first-zero support saturation delimit the local geometry. Exact finite dilation retains the still-unestimated prime/pole terms. The complete research notes, including supporting prime-entry/Fredholm statements and cross-reviews, are in ../ns55_kernel/. The index covers those files; this release is incremental, not cumulative.
Actual full build: 285 pages, zero undefined/duplicate references and zero overfull boxes. New manuscript pages 255–262 visually checked.
