Greptile Summary

Adds Live Activity support to the iOS app, enabling Dynamic Island and Lock Screen notifications that display real-time agent status updates. The implementation introduces a persistent activity that starts when the gateway connects and transitions through states (thinking, tool execution, streaming, done, idle, disconnected). Key features include 1s debounced updates for streaming content, on-device AI-powered task title generation, and comprehensive tool classification with friendly labels and SF Symbol icons.

The code integrates cleanly with the existing NodeAppModel by subscribing to operator gateway events and dispatching them to the LiveActivityManager singleton. The manager handles the full activity lifecycle with proper timer management, task cancellation, and memory safety using @MainActor isolation and weak references. The widget extension provides both Dynamic Island (compact/minimal/expanded) and Lock Screen banner views with appropriate visual states.

Architecture is sound with clear separation between the main app (LiveActivityManager), shared attributes (OpenClawActivityAttributes), and widget extension (OpenClawLiveActivity). The implementation follows Swift concurrency best practices and properly handles edge cases like activities being disabled, reconnection scenarios, and cleanup on disconnect.

Confidence Score: 5/5

• This PR is safe to merge with high confidence - well-architected Live Activity implementation with proper concurrency handling and no critical issues
• The implementation demonstrates excellent code quality with proper @MainActor isolation, weak reference usage to prevent retain cycles, comprehensive timer invalidation, and appropriate task cancellation. The integration with existing gateway event system is clean and non-invasive. No security vulnerabilities, memory leaks, or logical errors were identified. The feature is properly guarded with availability checks and handles disabled Live Activities gracefully.
• No files require special attention - all files show consistent high quality implementation

Closing as superseded by the focused replacement in #33591, which carries forward the two approved improvements from this PR (Live Activity connection status + stale/duplicate cleanup) with attribution retained. Thanks again @leepokai for the original implementation direction.
