July 2026: Sandbox URL Filtering Improvements and Refactor for vip-go-mu-plugins. Delivered targeted sandbox hardening by fixing admin URL handling and refactoring URL filtering into a generic function, enabling reuse and stronger isolation across filters. The work ensures administrative URLs resolve to sandboxed hostnames, reducing risk of leakage and improving safety for sandbox deployments. This aligns with the team's reliability and security goals, and lays groundwork for broader sandbox policy enforcement. Key outcomes include a robust admin_url routing that supports future admin-related filters with a single code path.
