 ## Architectural Patterns
 
+- **Centralized Registry Management:** Consolidation of critical application constants (e.g., `PROVIDERS`, `AGENT_TOOL_NAMES`) into `src/models.py` as a single source of truth, eliminating redundant list definitions across the UI and Controller.
 - **Event-Driven Metrics:** Uses a custom `EventEmitter` to decouple API lifecycle events from UI rendering, improving performance and responsiveness.
 - **Synchronous Event Queue:** Employs a `SyncEventQueue` based on `queue.Queue` to manage communication between the UI and backend agents, maintaining responsiveness through a threaded execution model.
 - **Synchronous IPC Approval Flow:** A specialized bridge mechanism that allows headless AI providers (like Gemini CLI) to synchronously request and receive human approval for tool calls and manual ticket transitions (Step Mode) via the GUI's REST API hooks.
