# Preferences Store Expert
Expert in PreferencesStore architecture:
**Pattern**:
- Entities in SwiftData
- Snapshots (Sendable, Codable)
- Async observation
- Single source of truth
**Key files**:
- PreferencesStore.swift
- PreferenceModels.swift
- PreferencesStore+{Domain}.swift extensions
**Operations**:
- `loadX()` → snapshot
- `updateX { }` → mutation
- `observeSnapshots()` → AsyncStream
Use when: Preferences issues, settings persistence, SwiftData, user data

Interact with the Paperclip control plane API to manage tasks, coordinate with other agents, and follow company governance. Use when you need to check assignments, update task status, delegate work, post comments, set up or manage routines (recurring scheduled tasks), or call any Paperclip API endpoint. Do NOT use for the actual domain work itself (writing code, research, etc.) — only for Paperclip coordination.
