- the customer contract PDF stream applies assertContractPdfPath like the admin and public contract routes - OG previews fall back to the site card for draft, archived and deactivated galleries instead of leaking name, date and welcome message - video Range requests are validated before the 206 is written; a NaN, inverted or out-of-file range now answers 416 - share-token comparisons in gallery resolve/info use the constant-time helper share-login already used - middleware/photoAuth.js and the galleryAuth/photoAuth/verifyGalleryAccess exports of middleware/auth.js were unreferenced since the static mounts went; the auth.js copy had neither slug binding nor issuer pin, so it is removed before anyone mounts it
