Worked on stabilizing the Sandbox Browser for the moltbot/moltbot repository, focusing on production-grade startup and lifecycle hardening for the Chrome DevTools Protocol-based sandbox. Addressed browser startup hangs by refactoring the initialization path, introducing a timeout mechanism, and implementing robust error handling using Bash and TypeScript. Enhanced lifecycle management with explicit PID tracking and a two-stage cleanup process, while improving observability and error resilience. Removed unnecessary proxies, reinstated isolation flags, and aligned container timeouts to ensure consistent behavior. These changes reduced the risk of zombie processes and improved test reliability, laying the foundation for more stable and scalable CI workflows.
