CHW-4810 UploadPackageNotRegistered

the uploaded package is not registered in this repository; ask an admin to create a package slug before publishing

Default message: the uploaded package is not registered in this repository; ask an admin to create a package slug before publishing
HTTP status: 403 (client)

Problem. Upload refused because the package is not listed under this repository. Cause. A package_slugs row must exist before an artifact can be published; Chainsaw enforces an explicit admin-managed publish permit. Fix. Ask an org admin to create the package slug (UI: Packages → Create slug; API: POST /api/packages) and retry. HTTP 403.
