Write a definitions module. Build it. Read every file it produced.
Press Build to see what this code generates.
This runs a reduced StewBeet pipeline. No item renders, no in-game manual, no dependency downloads.
Item renders need an OpenGL context, which the build container has no display for, so the in-game manual is off and items get their texture in place of an isometric render. There is no network at all, so dependency resolution and Smithed Weld merging are off, and nothing is archived, hashed or copied anywhere. Only the definitions module runs: no .mcfunction files, no bolt, no mecha, no sounds. Textures come from SimplEnergy, Stardust Fragment and the extensive template; any other item id gets a placeholder and a note in the log.
Each build gets 10 seconds of CPU, 20 seconds of wall clock and 512 MiB of memory, and returns at most 500 files or 4 MB.
