April 2025: Completed a major refactor of document namespaces and metadata to enable world collection configurability and standardized SystemOfType/_SystemMap, significantly improving maintainability and extensibility of the type system. Added CardsConfig handling for UI configuration, comprehensive stub scaffolding for applications/settings, ux, and sidebar to accelerate UI work and test coverage, plus extensive cleanup and test-reliability improvements. Upgraded core components to latest versions, moved imports to @common, and introduced NUE-based uniqueness safeguards. Implemented render context functions, added Combatant.Resource type with simplified initiative, and completed numerous code-review and test updates to stabilize the codebase. A targeted minor test fix completed the month, contributing to a more reliable CI pipeline.”,
