The (model) and (source) links should support showing line numbers like in a gist

By having the link show line numbers, you can more easily find errors and warnings

I would add these could be new pages that maintain the application instead of using the "raw" output.

Additionally, this should probably have proper back-links and stuff. This could all be achieved via JS on the main page without loading new pages. Prism.js seems like a good start.

Just thinking aloud.

Small concern, the source links now point to their sources rather than stored locally. The model however could use highlighting.
