+Feature: Deleting an article also deletes its images
+
+  As an authenticated RenewCMS user managing the CMS
+  I want deleting an article to also delete every image attached to it
+  So that removing an article doesn't leave orphaned image rows and files behind,
+    and so that an id that doesn't exist still answers 404 the same way every other
+    article write does
+
+  Background:
+    Given internal/domain/article.Article carries Images []*image.Image, populated by
+      ArticleRepository.Get via Preload("Images")
+    And internal/domain/image.Repository already exposes Delete(id uint32) error, which
+      on the real ImageRepository also removes the uploaded file from UPLOAD_DIR
+    And before this slice, DeleteArticleUseCase.DeleteArticle only called
+      articleRepository.Delete(id) and never touched image.Repository, so an article's
+      images were never deleted along with it
+    And this slice changes NewDeleteArticleUseCase to also take an image.Repository, and
+      changes DeleteArticleUseCase.DeleteArticle(id) to look up the article, delete every
+      image in its Images slice through image.Repository.Delete, and only then delete the
+      article itself through article.Repository.Delete
+    And this slice rewires api/dependecyInjection.go so
+      useCases.NewDeleteArticleUseCase(repos.ArticleRepo, repos.ImageRepo) supplies both
+      repositories
+    And DELETE /v1/article/{id} keeps sitting behind the jwtauth Verifier and
+      Authenticator group in api/router.go, unchanged from
+      features/write_not_found_errors.feature
+    And DELETE /v1/article/{id} keeps answering 204 with an empty body on success and 404
+      with body apperr.ArticleNotFoundErrorMessage for an id absent from the article
+      repository, backed by errors.Is(err, article.ErrArticleNotFound), unchanged from
+      features/write_not_found_errors.feature
+    And no image HTTP endpoint is mounted in api/router.go as of this slice, so cascading
+      image deletion is only observable through the image repository's state, not through
+      a separate HTTP call
+    And the use case deletes images in the order they appear in the article's Images
+      slice, and aborts on the first image.Repository.Delete error, leaving the article
+      and any not-yet-deleted images untouched, and answering the same generic 500 the
+      DeleteArticle handler already falls back to on any non-not-found error
+
+  Scenario: Deleting an article with images removes the article and every one of its images
+    Given a valid jwt cookie for a user with id 1
+    And the article repository contains an article with id 1 whose Images slice holds
+      image id 10 and image id 11
+    And the image repository contains images with id 10 and id 11
+    When the client sends DELETE /v1/article/1 with that cookie
+    Then the response status is 204
+    And the article repository no longer contains an article with id 1
+    And the image repository no longer contains an image with id 10 or id 11
+
+  Scenario: Deleting an article with no images still succeeds
+    Given a valid jwt cookie for a user with id 1
+    And the article repository contains an article with id 2 whose Images slice is empty
+    When the client sends DELETE /v1/article/2 with that cookie
+    Then the response status is 204
+    And the article repository no longer contains an article with id 2
+    And no call reaches the image repository's Delete method
+
+  Scenario: Deleting an unknown article still answers 404 and deletes no images
+    Given a valid jwt cookie for a user with id 1
+    And the article repository has no article with id 9999
+    When the client sends DELETE /v1/article/9999 with that cookie
+    Then the response status is 404
+    And the response body is the text "Article not found"
+    And no call reaches the image repository's Delete method
+
+  Scenario: Deleting an article still requires authentication
+    Given no jwt cookie is sent
+    And the article repository contains an article with id 1 whose Images slice holds
+      image id 10
+    When the client sends DELETE /v1/article/1 without a cookie
+    Then the response status is 401
+    And the article repository still contains the article with id 1
+    And the image repository still contains the image with id 10
+
+  Scenario: A failure deleting one of an article's images aborts the whole delete
+    Given a valid jwt cookie for a user with id 1
+    And the article repository contains an article with id 3 whose Images slice holds
+      image id 20 followed by image id 21
+    And the image repository contains images with id 20 and id 21
+    And the image repository's Delete fails for image id 20
+    When the client sends DELETE /v1/article/3 with that cookie
+    Then the response status is 500
+    And the response body is the text "Failed to delete article"
+    And the article repository still contains the article with id 3
+    And the image repository still contains the image with id 21

+# QA procedure: delete_article_cascades_images
+
+Package: `test` (black-box, extending `article_test.go`).
+
+## Setup shared by every case
+1. Call `validator.InitValidator()` once.
+2. Reuse `mockArticleRepo` (`test/article_test.go`) and `mockImageRepo`
+   (`test/image_test.go`) as-is. Extend `mockArticleRepo` seeding so a seeded article's
+   `Images []*image.Image` can hold pointers into the same `mockImageRepo.images` map used
+   by the test, so deleting through the article side and asserting through the image side
+   observe the same state.
+3. Add a call counter (or reuse the existing `failSwitch`/call-tracking pattern already in
+   `test/`) on `mockImageRepo.Delete` so a scenario can assert it was never called, and reuse
+   `mockImageRepo.fail` (the existing `failSwitch`) to make `Delete` fail for a specific
+   image id.
+4. Wire the real use cases over the fakes: `useCases.NewCreateArticleUseCase`,
+   `useCases.NewGetArticleUseCase`, `useCases.NewListArticlesUseCase`,
+   `useCases.NewUpdateArticleUseCase`, and the new two-argument
+   `useCases.NewDeleteArticleUseCase(articleRepo, imageRepo)`. Build `article.NewHandler(...)`
+   with the same constructor shape it already has (the use case's internal dependency count
+   changes, not the handler's).
+5. Build a test `jwtauth.New("HS256", []byte("test-secret"), nil)`.
+6. Mount the routes on a fresh `chi.NewRouter()` mirroring `api/router.go`'s current shape:
+   `GET /` under `jwtauth.Verifier` only; `GET /{id}`, `POST /`, `DELETE /{id}`,
+   `PATCH /{id}`, `PATCH /{id}/publish`, `PATCH /{id}/unpublish` under `jwtauth.Verifier` +
+   `jwtauth.Authenticator`.
+7. Mint a valid jwt cookie for user id 1: `token.Encode(map[string]any{"user_id": uint32(1)})`,
+   set as the `jwt` cookie on the relevant `httptest.NewRequest`.
+
+## HTTP checks
+8. Seed `imageRepo.images[10]` and `imageRepo.images[11]`, then seed
+   `articleRepo.articles[1] = article.Article{ID: 1, Title: "Backyard Renovation Update",
+   Images: []*image.Image{imageRepo.images[10], imageRepo.images[11]}}` (pointers into the
+   same map). Send `DELETE /v1/article/1` with the valid cookie -> status `204`; assert
+   `articleRepo.articles` no longer has key `1`; assert `imageRepo.images` no longer has
+   keys `10` or `11`.
+9. Seed `articleRepo.articles[2] = article.Article{ID: 2, Title: "Draft: Kitchen Remodel"}`
+   with a nil/empty `Images` slice. Send `DELETE /v1/article/2` with the valid cookie ->
+   status `204`; assert `articleRepo.articles` no longer has key `2`; assert the image-delete
+   call counter is `0`.
+10. Empty `articleRepo`, empty `imageRepo`. Send `DELETE /v1/article/9999` with the valid
+    cookie -> status `404`, body `"Article not found\n"`; assert the image-delete call
+    counter is `0`.
+11. Seed `imageRepo.images[10]` and `articleRepo.articles[1]` with `Images` holding image id
+    10, per step 8's pattern. Send `DELETE /v1/article/1` with **no** cookie -> status `401`;
+    assert `articleRepo.articles[1]` is still present and `imageRepo.images[10]` is still
+    present.
+12. Seed `imageRepo.images[20]` and `imageRepo.images[21]`, then seed
+    `articleRepo.articles[3] = article.Article{ID: 3, Title: "Kitchen Progress Photos",
+    Images: []*image.Image{imageRepo.images[20], imageRepo.images[21]}}` (image 20 before
+    image 21 in the slice). Arm `imageRepo.fail` so `Delete` returns an error only when
+    called with id `20` (leave id `21` unarmed). Send `DELETE /v1/article/3` with the valid
+    cookie -> status `500`, body `"Failed to delete article\n"`; assert
+    `articleRepo.articles[3]` is still present; assert `imageRepo.images[21]` is still
+    present (never reached because the delete aborted on image `20` first).
+
+## Manual verification (not exercised by the Go test)
+- Real cascading delete against a real SQLite file and real `UPLOAD_DIR`: confirm that after
+  `DELETE /v1/article/{id}` on a real running instance, the uploaded image files under
+  `UPLOAD_DIR` for that article are gone from disk and the `images` table no longer holds
+  those rows, and that no orphaned rows are left behind in the `article_images` join table.
+  Not exercised by `task test` (fakes only); requires `task dev` or a built `task build`
+  binary with a scratch DB/upload dir.
+- SPA-visible behaviour: confirm the back-office article deletion flow (if/when one exists)
+  reflects that any images shown for that article are gone too. No such UI exists yet as of
+  this slice.
+- No SMTP involvement.
