 # Daily Notification Plugin - Development TODO
-## Current Status
+**Last Updated**: 2025-08-26 11:17:26 UTC  
 **Current Branch**: research/notification-plugin-enhancement  
 **Status**: 🔄 **RESEARCH & ANALYSIS PHASE**
-**Phase 1: Foundation & Testing (Weeks 1-2) - COMPLETED ✅**
+## 🎯 **NEW REQUIREMENTS ANALYSIS**
 ### **Callback & API Integration Requirements**
 Based on user feedback analysis, the plugin needs enhanced callback mechanisms and dual scheduling methods:
 1. **API Callback Integration** - Accept callbacks for external API calls and database storage
 2. **Dual Scheduling Methods** - Separate methods for content fetching vs. user notification
 3. **Reporting Service Integration** - Support for external reporting and analytics services
 ### **Current Implementation Gap Analysis**
 - ✅ **Basic scheduling**: Single `scheduleDailyNotification` method exists
 - ❌ **Callback system**: No callback mechanism for external services
 - ❌ **Dual scheduling**: No separation between content fetch and user notification
 - ❌ **API integration**: Limited to basic URL fetching without callback support
 - ❌ **Database storage**: No callback support for external database operations
