 Regression: every existing Editor, Articles, ArticlesPagination, ArticlesPageSizeMemory and Profile spec now sees the new calls. Give them default mocks (one site, one author, author null where relevant) rather than loosening unmocked-call checks, and show that they still pass.
 
 1. MetaSection: collapsed summary "Inès Duarte"; open/closed Examples (sites x authors); remembered choice wins over auto-open; same key in the desktop sidebar and the mobile sheet; mobile closed in the Details sheet; loading skeleton; no section on 404; summary variants.
-2. SiteSelect: absent with one site; present with helper "Canonical host: ..."; options with name and host and the default first; choosing marks "Unsaved changes"; the PATCH contains `site_id` and only the changed fields; GET /v1/site/ failure renders no select and no notice.
+2. SiteMoveField: absent with one site; present with helper "Canonical host: ..."; activating it opens the Move article panel (the old SiteSelect, the staged `site_id` edit and its PATCH are removed, see localization_translation_flows); GET /v1/site/ failure renders no field and no notice.
 3. AuthorList: Primary label, handle, remove, truncation with title and aria-label; keyboard reorder (grab, ArrowUp/Down, drop, Escape, live region text including dropped and cancelled); pointer reorder (use the sortable test helper; assert order and "Unsaved changes"); removing the last author shows the no-byline text; PATCH `author_ids` order, `[]` when emptied, absent when unchanged.
 4. AuthorSelect: opens with GET /v1/author/ size 100; only sizes 5, 25, 50 or 100 are ever sent (other sizes answer 400); `q` search beyond the first 100; checked and dimmed items do nothing when activated; append on pick; "Create author…" per role (owner, admin, verified); no-match message with and without the create row; error state with "Try again".
 5. Create author dialog: prefilled name and auto slug; POST body; appended to the list and "Unsaved changes"; the article's authors are not sent before Save; "This is me" only when author is null (default unchecked) and sends `user_id`; session store updated; slug taken and the "Use zoe-lambert-2" action; failure Examples; 403 toast.
