…yServiceProviders warning in test fixture - BlogPost.AssignCategory and RemoveCategory now increment Version so UpdateAsync concurrency check (OriginalValue = Version-1) is correct - TestContextFactory caches DbContextOptions and suppresses CoreEventId.ManyServiceProvidersCreatedWarning to fix 7 failing integration tests in category test suite Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
… seeding Changed InsertOneAsync to ReplaceOneAsync with IsUpsert=true for the General category in the seed command. This makes the seed operation idempotent so AppHost integration tests don't fail with DuplicateKey when seeding runs multiple times in the same test session.

Changes:
- Added Category domain entity, repository/data access, CQRS handlers/validators, and DI registration.
- Added Admin-only Categories CRUD UI and navigation link; added category dropdown + author read-only display on blog post Create/Edit pages.
- Updated AppHost seed data and test infrastructure to support categories and fix concurrency/testcontainer stability issues.

| ## 2025-07-XX — Issue #339 Category Frontend (branch `squad/339-category-backend`) | ||
|
|
||
| ### What I Implemented | ||
|
|
||
| - **Categories CRUD admin page** at `/admin/categories` (`src/Web/Features/Categories/List/Index.razor`) — inline create, inline edit, inline delete with confirmation modal, Admin-only | ||
| - **Categories nav link** in `NavMenu.razor` (Admin-only, desktop + mobile) | ||
| - **Blog post Create form**: category dropdown with null-safe loading; `GetCategoriesQuery` result checked with `is { Success: true }` pattern | ||
| - **Blog post Edit form**: category dropdown pre-populated from `BlogPostDto.CategoryId`; author name shown read-only; parallel task loading via `Task.WhenAll` | ||
|
|
|
|
||
| ## Context | ||
|
|
||
| During PR gate work, `gh pr view --comments` may fail due GraphQL field deprecations (for example, classic project card access). Gate flow still requires Copilot/Codecov and reviewer-comment evidence. |
| ## Anti-Patterns | ||
|
|
||
| - Assuming no review comments exist just because `gh pr view --comments` failed. | ||
| - Merging without reading Copilot inline comments due CLI query failures. |
