   - 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`.
