In the following case study, the AI coding agent rebuilds a core system invariant in just three days, with minimal human input, running 31 verification passes and correcting 201 errors, before shipping code with zero bugs, zero regressions, and zero technical debt.

Disclaimers:

This case study is NOT: - a project written from scratch - yet another Rust transpilation - a clone of an open-source project found in the LLM's training data - a Super Mario clone in HTML

It IS: - a complex application maintenance task, about a unique problem with no open-source equivalent, to the best of my knowledge - a true engineering feat, 90% driven by the agent powered by ChatGPT 5.6 Sol Reasoning MAX - 201 bugs, ambiguities, and architectural flaws automatically fixed by the AI agent - proof that one can program perfectly within complex legacy software without any need for human code review

Feedback welcome.
