The Triad pattern coordinates UI and data when extending core modules without forking. It combines an enricher, a widget, and an injection to graft new capabilities onto existing forms, tables, and API responses.

Scaffold a modular plugin extension by using the UMES wizard to generate enrichers, widgets, interceptors, guards, and subscribers. After scaffolding the defined extension directory structure, run yarn generate to register changes and yarn dev to verify the extension in the target UI.

The required directory structure for UMES extension mechanisms includes data/enrichers.ts, widgets/injection/, api/interceptors.ts, data/guards.ts, and subscribers/. A YAML frontmatter is also required to define the extension configuration.

Yes, you can intercept API responses and add mutation guards to existing forms using UMES extension mechanisms. The system supports API interceptors and mutation guards to safely augment existing behavior without changing core code.

UMES supports event subscribers and component replacements for dashboards, forms, and APIs. These extension mechanisms allow developers to safely augment existing behavior and coordinate UI changes across different module surfaces.
