In the case the file was only intended to be there for a temporary step, I wanted that working before involving the database, which I believe also won't work because you can't do system calls at comptime. Ultimately if you go down that path, whatever would be supplying the file could just as easily (or perhaps easier) be supplying zig code and you're still reliant on some sort of per-processor.
