Vyasa Extension Refactor Audit and Execution Plan

Final Target Mental ModelURL copied

Core should answer:

What content roots exist?

What request is this?

What user roles does this request have?

Which extensions are enabled?

Which extension owns this route, slot, fence, asset, or storage namespace?

How do I call the registered provider safely?

Extensions should answer:

How does Mermaid render?

How do Tasks parse and draw?

How does the default layout look?

How do bookmarks store and render?

How does search rank files?

How does a slide deck work?

That split is the developer-friendly layer. Anything else is just moving boxes around.
