This PR looks very AI-generated. We're dealing here with a very complex codebase, and a very old codebase. It's very easy to make a change in thus code which has far-reaching side effects. I am not inclined to accept contributions without knowing they come from a real person with a good working knowledge of the many idosyncracies of this nonsense code. I'd like to know more about your test plan. Exactly what didn't report errors or warnings? CI? Don't have any. Were you on a Solus system, testing how actual package operations were affected? If not, you need to be. "Project Diagnostics" makes no sense in context. The code might not be very good in places (in fact, I guarantee that it isn't), but it does work. Code churn like this just for the sake of making itook nicer is very suspicious to me. A laudable goal, but this thing is the foundation of peoples' systems. Any and all changes need to be carefully considered by real people familiar with the project, and I'm not convinced that these have been. |

Thank you for the detailed feedback. I understand your concern, especially considering how critical eopkg is to Solus systems and how fragile older codebases can become over time. To clarify a few points:
When I mentioned “Project Diagnostics”, I was referring to:
I fully agree that “the code works” is the most important thing here. The goal of the PR was not cosmetic churn for the sake of style. The intention was to improve reliability and maintainability in targeted sections that appeared unnecessarily fragile or difficult to reason about. I also understand the concern regarding AI-assisted development. I did use modern tooling during development, but the final responsibility, testing, review, and understanding of the code changes were mine. I would not submit modifications to a package manager affecting users’ systems without manually reviewing and testing them first. That said, I think it is important to evaluate the actual technical impact of the patch itself rather than dismissing it primarily based on how it “looks.” Older codebases often naturally resemble patterns that modern tooling tries to clean up, but that does not automatically make every refactor unsafe or meaningless. If specific parts of the PR are considered risky, I would genuinely appreciate line-by-line feedback so I can revise or reduce the scope accordingly. |

Addressed the requested review feedback in the latest commit:
Thanks for the review. |

If you don't mind my asking, I'm curious if your responses were your own writing or AI generated? I've heard of people who have certain writing styles that are similar to the writing patterns of AI and I wanted to know if maybe that was happening here, or the responses really were LLM generated. |

That's a fair question, and I understand the concern given how important and sensitive this codebase is. I do use modern development tools during improving productivity, but the investigation, testing, debugging, and final validation of the changes were done manually by me on a real Solus installation. I would not submit modifications to a package manager without reviewing the affected code paths carefully and verifying the behavior myself. The review feedback has also been helpful in reducing unnecessary churn and aligning the patch more closely with the project's existing conventions. I appreciate the scrutiny honestly, for a core system component like eopkg, that level of caution makes sense. |

Thanks for your comment, and your candidness, but it didn't answer my question. Are you using an LLM to assist in writing your replies, like that comment? |
|
Fair question, yes, I’ve used modern tooling to help refine some of my written replies during the discussion. But the actual debugging, testing, and code changes were done manually by me on my Solus install. I wasn’t just generating patches and submitting them blindly. I understand the concern though, especially for a project like eopkg where even small changes can have wider effects. |
