 # QA: Paginated article listing (API)
 
+> Superseded in part by roles_permissions_content_scope: the article routes are gated by the content.* permissions of the caller's role (content.create, content.update, content.delete and content.publish; a refusal is 403 "missing_permission" with the header X-Missing-Permission), and content.read decides which drafts show: every draft at all, only the caller's own drafts at own, none otherwise. A draft the caller may not read answers 404 "Article not found", and a role that cannot be resolved is treated as holding no permission.

 ## HTTP-level (Go, `test/`, `task test`)
 
 Build `article.NewHandler(...)` over the real `ListArticlesUseCase` and a fake `article.Repository` (extend `mockArticleRepo` in `test/article_test.go`, keeping type names unique across files). The fake implements the interface contract: paging (Page/Size 0 = unpaged), q/status filtering, ordering updated_at DESC then id DESC, total, and the visibility counts. Mount on a fresh `chi.NewRouter()` mirroring `NewArticleRouter` in `api/router.go` (GET / under `jwtauth.Verifier` only, test `jwtauth.New("HS256", ...)`). Call `validator.InitValidator()`. Use a user fake for the verified, unverified and missing cases, as in `test/public_article_listing_test.go`. No live server, no SQLite file.
