Okay, I'm looking at it. Now what?

This file is exactly what I'm talking about.

Take the loadInitialMessage function: It's encumbered with real world incremental requirements. You can see exactly the bolted-on conditionals where they added features like --teleport, --fork-session, etc.

The runHeadlessStreaming function is a more extreme version of that where a bunch of incremental, lateral subsystems are wired together, not an example of superfluous loc.

The file is more than 5000 lines of code. The main function is 3000. Code comments make reference to (and depend on guarantees in connection with) the specific behavior of code in other files. Do I need to explain why that's bad?

By real-world polish, I don't mean refining the code quality but rather everything that exists in the delta between proof of concept vs real world solution with actual users.

You don't have to explain why there might be better ways to write some code because the claim is about lines of code. It could be the case that perfectly organizing and abstracting the code would result in even more loc.
