# Plan 11-06 — Dead-Code Cleanup & Final Measurement

## Objective

Delete unreferenced frontend code and capture the final bundle report after all Phase 11 optimizations are complete.

## Tasks

1. Run dead-code searches for unreferenced components, stores, helpers, imports, and old route views.
2. Explicitly classify these known suspects before deleting or retaining:
   - `frontend/src/views/AccountView.vue` (`/account` currently redirects to `/settings`)
   - `frontend/src/components/admin/__tests__/AdminAiConfigTab.test.js`
   - `frontend/src/components/admin/__tests__/AdminQuotasTab.test.js`
   - `frontend/src/components/admin/__tests__/AdminUsersTab.test.js`
3. Confirm `HomeView.vue`, `FolderView.vue`, and `AdminView.vue` remain absent.
4. Delete files with no active route and no active import in the same commit as their references are removed.
5. Remove unused imports and stale tests that target deleted files; keep behavior tests that still protect live surfaces.
6. Run the final analyzer build and write `.planning/perf/phase11-final.html`.
7. Add `.planning/perf/phase11-final-summary.md` comparing baseline vs final bundle size, chunk count, and largest chunks.
8. Produce `11-VERIFICATION.md` mapping every Phase 11 requirement to code/test/build evidence.

## Acceptance Criteria

- CODE-07 is satisfied: no dead files, unused route components, unused stores, or unused imports remain.
- Known suspects are each documented as deleted or intentionally retained.
- Final bundle report and summary are committed under `.planning/perf/`.
- Baseline and final reports are both present.
- `cd frontend && npm run test -- --run` passes.
- `cd frontend && npm run build` passes.
- Phase 11 verification maps VISUAL-01..04, RESP-01..05, CODE-07, PERF-02, and PERF-03 to concrete evidence.
