Exact26 code/test/architecture/register blobs from621b41fa3; campaign ledger and lead verification included. Independent retail and production/lifetime/ABI reviews PASS. Lead69Core/176App/2actualshader pixels, viewer/clear/NaN negative controls fail as intended, exact restoration69PASS. AP68retired; AP16/35/85 residuals honest. Fresh campaign Release and graphical lighting proof still owed; temporary observer cleanup contract conditional. FPS deferred; no G4 or main merge.
