Worked on the trycua/cua repository to address focus-handle leaks in SystemFocusStealPreventer, building a four-layer leak-prevention mechanism using scoped APIs to improve resource management across asynchronous boundaries. Applied expertise in Swift and concurrency management to refactor lease teardown and crossfade logic, closing suppression gaps and reducing focus-trap scenarios that previously led to high CPU usage. Expanded unit testing with eight new tests and achieved full docstring coverage, ensuring robust validation and maintainability. Introduced a deadline safety net and enhanced observability for leak diagnosis, delivering a production-ready API surface that improves end-user focus reliability and lowers ongoing support risk.

May 1, 2026May 2026 monthly summary for cua project (trycua/cua): Focused on eliminating focus-handle leaks in SystemFocusStealPreventer and hardening resource management across asynchronous boundaries. Delivered a four-layer leak-prevention mechanism with scoped APIs, significantly reducing focus-trap scenarios and associated high CPU spikes. Strengthened test coverage (8 new tests; 0.7s total runtime) and introduced a robust deadline safety net and observability to surface latent leaks quickly. Reworked lease teardown and crossfade logic to close suppression gaps, adding two regression tests that lock in contract behavior. All tests pass (36/36) with improved code documentation (100% docstring coverage across four files). Technologies demonstrated include Swift/ARC, asynchronous patterns, scoped resource management, regression testing, and enhanced observability. Business value delivered includes improved end-user focus reliability, lower support risk, and a more maintainable, production-ready codebase."
