+
+

Implementation Plan

+ +

This spike validates the metadata panel UI design and interaction patterns.

+ +

Goals:

+ + +

Content area with editor. See [[architecture-design]] for system design.

+ +

Related to #backend and #database tags.

+ +

This panel demonstrates how metadata editing would work in the yak-shears editor. Changes to fields trigger simulated updates (in real implementation, these would use HTMX to update the server).
