In January 2026, focused on stabilizing the Sandbox Service lifecycle within the apple/container repository to prevent flaky behavior during rapid stop/start cycles. The core change forcefully terminates the SandboxService process on container exit and defensively cleans up stale services before registering new ones, eliminating reconnections to processes in the shuttingDown state and preventing premature container deletions during rapid restarts. This improves reliability, reduces failure rates during rollouts, and strengthens container lifecycle isolation. The work lays a foundation for more robust sandbox management and easier operational support.
