There are several generated files checked in to the main repository out of convenience:

• Makefiles
• Visual Studio project files
• Scripting system headers (src/script/(ai,game,template)/)

These files should always be kept updated when a commit modifies the source files they are generated from. The commit checker should verify that re-generating these files do not produce a diff, and fail if there is a difference.

Other generated files checked in are baseset definition files, which are built from a template and translations. Since these are closely tied to translations they should likely be handled by Eints, out of scope of this ticket.

Lastly there is openttd.grf, which requires additional tooling to generate, and might have binary differences depending on the exact versions of the tools used. It should possibly be maintained by a separate job, out of scope of this ticket.
