## Overview

Pavanmaxxer is a desktop task manager driven by short text commands. The main user workflow is JavaFX input → command classification and parsing → application coordination → task-list operations, with a response rendered in the conversation window. Creation supports todos, dated deadlines and timed events; list, search, completion toggles, deletion and duplicate warnings are handled in the same core. The coordinator loads and saves a text snapshot. Edges reflect shown calls and documented capabilities; resource-level UI wiring and unsampled implementation details are not expanded.
