    participant P as Player
    participant CM as Container Manager
    participant AC as Access Controller
    participant SC as Storage Controller
    participant UI as UI Controller
    participant AN as Animation Controller
    
    P->>CM: Request Container Access
    CM->>AC: Check Access Permissions
    
    alt Access Granted
        AC->>CM: Permission Approved
        CM->>AN: Start Open Animation
        CM->>SC: Load Container Contents
        SC->>UI: Display Container Interface
        AN->>UI: Animation Complete
    else Access Denied
        AC->>CM: Access Forbidden
        CM->>UI: Display Lock Interface
    end
    
    loop Container Open
        P->>UI: Perform Item Actions
        UI->>SC: Process Item Operations
        SC->>CM: Update Container State
    end
    
    P->>UI: Close Container
    UI->>AN: Start Close Animation
    UI->>SC: Save Container State

Loot Generation Pattern

• Dynamic Generation: Procedural loot based on container type and player level
• Rarity Distribution: Weighted random generation with luck modifiers
• Context-Sensitive: Loot appropriate to container location and story context

Multi-Access Pattern

• Concurrent Access: Multiple players can access same container simultaneously
• Action Queuing: Queue conflicting actions for fair resolution
• State Synchronization: Real-time updates across all accessing players

Performance Optimization

Memory Management

• Lazy Loading: Load container contents only when accessed
• Smart Caching: Cache frequently accessed container data
• Garbage Collection: Clean up unused container instances efficiently

UI Optimization

• Virtual Scrolling: Efficiently display large container inventories
• Incremental Search: Real-time search with minimal performance impact
• UI Pooling: Reuse UI elements for multiple containers

Network Optimization

• Delta Synchronization: Only send changed container data
• Priority Queuing: Important container changes get transmission priority
• Compression: Compress container state data for network efficiency
