Upstreaming dashboard

The eventual goal of the Toric project is to be fully upstreamed to Mathlib.

As such, it is crucial to continuously organise upstreaming from Toric to Mathlib. The way we organise this is with the following two lists, showing files with no Toric dependencies depending on whether they contain the keyword sorry or not.

Files ready to upstream

The following files are sorry-free and do not depend on any other Toric file, meaning they can be readily PRed to Mathlib.
