fix(frontend): correct AppCore example images initialization

 | --- | --- | --- | --- | --- |
 | Phase 0 | Establish baseline tooling | Add Node test runner, jsdom environment, and seed smoke tests | ✅ Complete | Vitest + jsdom configured, example state tests committed |
 | Phase 1 | Cover state management logic | Unit test selectors, derived data helpers, and storage utilities under `static/js/state` and `static/js/utils` | ✅ Complete | Storage helpers and state selectors now exercised via deterministic suites |
-| Phase 2 | Test AppCore orchestration | Simulate page bootstrapping, infinite scroll hooks, and manager registration using JSDOM DOM fixtures | 🟡 In Progress | AppCore initialization specs landed; DOM fixtures now cover page feature wiring (context menus + infinite scroll); next focus is scroll hooks and manager wiring |
+| Phase 2 | Test AppCore orchestration | Simulate page bootstrapping, infinite scroll hooks, and manager registration using JSDOM DOM fixtures | ✅ Complete | AppCore initialization + page feature suites now validate manager wiring, infinite scroll hooks, and onboarding gating |
 | Phase 3 | Validate page-specific managers | Add focused suites for `loras`, `checkpoints`, `embeddings`, and `recipes` managers covering filtering, sorting, and bulk actions | ⚪ Not Started | Consider shared helpers for mocking API modules and storage |
 | Phase 4 | Interaction-level regression tests | Exercise template fragments, modals, and menus to ensure UI wiring remains intact | ⚪ Not Started | Evaluate Playwright component testing or happy-path DOM snapshots |
 | Phase 5 | Continuous integration & coverage | Integrate frontend tests into CI workflow and track coverage metrics | ⚪ Not Started | Align reporting directories with backend coverage for unified reporting |

 - [x] Document DOM fixture strategy for reproducing template structures in tests.
 - [x] Prototype AppCore initialization test that verifies manager bootstrapping with stubbed dependencies.
 - [x] Add AppCore page feature suite exercising context menu creation and infinite scroll registration via DOM fixtures.
+- [x] Extend AppCore orchestration tests to cover manager wiring, bulk menu setup, and onboarding gating scenarios.
 - [ ] Evaluate integrating coverage reporting once test surface grows (> 20 specs).
 - [ ] Create shared fixtures for the loras and checkpoints pages once dedicated manager suites are added.
+- [ ] Draft focused test matrix for loras/checkpoints manager filtering and sorting paths ahead of Phase 3.
 
 Maintaining this roadmap alongside code changes will make it easier to append new automated test tasks and update their progress.
