> Calendar State Refactor, Drag-and-Drop Fixes, and Layout Updates

# February 8th, 2026

**Revamping the Calendar Experience**

Today's work centered on significantly improving the scheduling interface, moving from local state to a robust global store, and refining the drag-and-drop interactions.

***

## 🏗️ Calendar State & Interaction Overhaul

### Global State Management

**Refactor:** Migrated calendar event state from local `useState` in `verify.tsx` to a new global store using **Zustand**.

* **Store Actions:** Implemented actions for adding, updating, and selecting events.
* **Debugging:** Added a custom logger middleware to track state changes effectively.

### Robust Drag Handling

**Fix:** Resolved a critical bug where events would disappear or throw invalid date warnings after dragging.

* **Logic Update:** Added robust parsing to correctly extract start/end times from various return formats (ISO strings, Date objects).
* **Data Integrity:** Ensured exclusive handling of `dateTime` (timed events) vs `date` (all-day events) to maintain valid event structures.

## 📅 UI/UX Enhancements

### Custom Date Picker & Header

* **New Component:** Added `DatePickerModal` matching the system UI style.
* **Navigation:** Integrated the date picker and a "Today" quick-nav button directly into the Schedules header.

### Full Event Interactivity

* **Drag-to-Move**: Enabled seamless moving of events.
* **Drag-to-Create**: allowed creating new events by dragging on empty slots.
* **Resize**: Implemented intuitive event resizing.
* **Responsiveness**: Improved drag gestures with instant-press recognition.

### Visual Polish

* **Selection**: Implemented tap-to-select and background tap-to-deselect.
* **Theme**: Updated calendar styles with minimalist time labels, custom font sizes, and optimized dark mode colors.
* **Cleanup**: Removed redundant `schedule.tsx` and `verify.tsx` screens.

## 📱 Layout Architecture

### Switch to Tabs Layout

**Refactor:** Replaced `Stack` navigation with `Tabs` in `_layout.tsx` to improve state persistence.

* **Persistence:** This prevents pages from unmounting and losing state when navigating between tabs.
* **Bottom Bar**: Updated `BottomTabBar` to implement standard `BottomTabBarProps`, using `state.routes` and `descriptors` for correct tab handling.
* **Fixes**: Resolved white background artifacts on the `schedules` screen by wrapping content in a `View` container.
* **Styling**: Removed the default top border from the tab bar for a cleaner dark theme look.
