 ### Tests for User Story 4
 
-- [ ] T044 [P] [US4] Add catalog coverage guard test in `tests/Feature/OpsUx/OperationCatalogCoverageTest.php`
-- [ ] T045 [P] [US4] Add canonical “View run” helper usage guard test in `tests/Feature/OpsUx/CanonicalViewRunLinksTest.php`
-- [ ] T046 [P] [US4] Add unknown-type runtime label test in `tests/Feature/OpsUx/UnknownOperationTypeLabelTest.php`

 ### Implementation for User Story 4
 
 - [x] T047 [US4] Ensure OperationRunResource type label rendering never shows raw type in `app/Filament/Resources/OperationRunResource.php`
 - [x] T048 [US4] Ensure Monitoring Operations page type labels never show raw type in `app/Filament/Pages/Monitoring/Operations.php`
-- [ ] T049 [US4] Ensure any remaining “View run” links use canonical helper in `app/Support/OperationRunLinks.php`
+- [x] T049 [US4] Ensure any remaining “View run” links use canonical helper in `app/Support/OperationRunLinks.php`
 
 **Checkpoint**: Drift prevention is enforced in CI.
