- favorites-api.ts: FavoriteLink type + fetchFavorites/createFavorite/updateFavorite/deleteFavorite
all use credentials: include and API_URL/favorites
- favorites-widget.tsx: list/grid view, inline add/edit/delete in edit mode,
icon + letter fallback, rel=noreferrer + target=_blank, no dangerouslySetInnerHTML (T-08-07)
- useEffect deps fixed to [instanceId] only — excludes t() to prevent re-fetch on each render
- page.tsx: wireFavoritesWidget(FavoritesWidget) wired
- Full test suite: 81/81 pass (17 test files)
- Web TypeScript: clean
- fetchFavorites called with instanceId (widgetId scope, Pitfall 3)
- covers add/edit/delete, empty state, list/grid toggle, letter fallback
- tests fail: favorites-widget.tsx and favorites-api.ts do not exist yet
