📋 Decision Context

Question:

What is the root cause of the "No Widgets" rendering problem in generated platforms?

Task: Session 144: Platform building E2E gap audit

🎯 Decision Made

Chosen:

Widget shape mismatch: makeWidget() in backend-setup.phase.ts produces {config, position:{x,y,w,h}} but Widget interface requires {properties, name, position: ResponsiveValue, size: ResponsiveValue, styles, rotation, zIndex}

Options Considered:

• No alternatives documented

💭 Reasoning

Verified by reading both the Widget interface in core-models/widget.types.ts and the makeWidget() function in backend-setup.phase.ts. The field name mismatch (config vs properties) and missing required fields (name, size, styles, rotation, zIndex) cause the page renderer to see zero valid widgets. Additionally, the position shape is flat {x,y,w,h} instead of ResponsiveValue wrapper. This single mismatch is the primary cause of the No Widgets display across all generated pages.
