The installable Mayfly terminal UI bundle for dsh. Its flat cordis.patch.yml composition adds ordinary sibling rows over dsh-base: a set of dsh support rows and the Mayfly product rows.

Plugins inherit native dsh services directly and opt into terminal UI with mayflyPanes, mayflyStatus, mayflyOverlays, and mayflyEditorExtensions. The current Agent is available through mayflyCurrentAgent. Official Mayfly features use those same services.

The mayfly-cordis preset includes skills for temporary prototyping, durable ordinary Cordis plugin authoring, and composition editing. No special Mayfly manifest, capability host, adapter, or plugin-author CLI is required.
