   - `src/middleware.ts`: Route-level auth and admin role verification guard.
 
 - **Completed So Far:**
+  - Rewrote entire Git commit history with active local Git identity across all branches and tags, and force-pushed to self-hosted Gitea remote origin.
   - Conducted full audit of codebase against all specification items in `AGENTS.md`.
   - Verified 100% implementation of core features: n-depth recursive checklist, real-time subtask synchronization, modular blocks & split resizer, 3-way theme (VSCode dark / pastel light / system), global `UserPrefs` customization, Labs Kanban view, and mobile bottom sheet.
   - Enhanced CalDAV / DAVx⁵ synchronization endpoint (`src/app/api/dav/[...path]/route.ts`) with full RFC 4791 support: `OPTIONS`, `PROPFIND` (principal & calendar collection discovery), `REPORT` (calendar-query/multiget), `PUT` (task upsert from VTODO), and `DELETE`.

   - Implemented full-fidelity standard Task Export pair (`/api/export`) supporting RFC 4180 / TickTick-compatible CSV with UTF-8 BOM, and RFC 5545 iCalendar (`.ics` VTODO) format.
   - Added Export modal in Sidebar user popover menu supporting format selection, target list filtering, completed tasks inclusion toggle, and seamless Demo mode client-side Blob generation.
   - Added localized i18n strings for Export across English, Korean, and Japanese.
+  - Migrated repository and commit history to self-hosted Gitea remote origin.
+  - Configured production multi-stage `Dockerfile` and automated Gitea Actions CI workflow (`.gitea/workflows/docker-build.yaml`) for building & pushing container images to Gitea Container Registry.
   - Validated that `npm run lint` and `npm run build` execute with 0 errors and 0 warnings.
 
 - **Next Steps (Todo):**
