Cluster Folder View - Implementation Summary

✅ Feature Status: COMPLETE

Feature: Folder View Tab for Cluster Pages
Design Approach: Virtual Root with Library Folders (Option 1)
Implementation Date: 2025-10-12
Total Time Spent: ~3 hours

📋 Executive Summary

Successfully implemented a hierarchical folder navigation system for cluster pages that allows users to browse media files organized by their physical folder structure, while maintaining the cluster grouping concept.

Key Achievement: Users can now choose between:

🔑 Key Features

1. Virtual Root

Purpose: Entry point showing all cluster libraries
Display: Library cards with statistics
Statistics: Item count, video/photo/text counts, storage size
Theming: Cluster color applied to library cards
Action: Click to navigate into library

Format: Cluster Name > Library > Folder > Subfolder
First Breadcrumb: Cluster name with cluster color
Clickable: Jump to any level in hierarchy
Visual: Home icon on cluster name

3. Folder Hierarchy

Source: Reads actual file system structure
Display: Folders first (sorted alphabetically), then files
Metadata: Ratings, bookmarks, thumbnails for media files
Navigation: Click folders to drill down, click files to view

4. Media Integration

Video Files: Opens UnifiedVideoPlayer
Photo Files: Opens PhotoViewer
Text Files: Opens TextViewer
Ratings: Star rating system (click same star to unstar)
Bookmarks: Folder and media bookmarking

5. Security

Path Validation: Ensures requested path belongs to cluster
Access Control: Returns 403 for unauthorized paths
Error Handling: Graceful handling of missing/invalid paths

🧪 Testing Guide

Quick Test Flow

Open cluster page → Should default to Folders tab
Verify virtual root → See library cards with stats
Click library → Navigate to library root
Check breadcrumb → Shows Cluster > Library
Click folder → Drill down into subfolder
Click video → Video player opens
Close player → Returns to folder view
Click cluster in breadcrumb → Returns to virtual root

Test Scenarios

Scenario	Expected Behavior
Virtual root with libraries	Display library cards with statistics
Virtual root without libraries	Show empty state with helpful message
Click library card	Navigate to library root, update breadcrumb
Click folder	Navigate into folder, update breadcrumb
Click media file	Open appropriate viewer modal
Click breadcrumb	Navigate to that level
Click back button	Return to parent or virtual root
Path outside cluster	Show 403 error
Non-existent path	Show 404 error
Large folder (1000+ items)	Pagination handles gracefully
