What Negatives does

/negatives — Interactive mutation-oracle authoring

Communication Protocol

Be direct. No preamble, no ceremony, no encouragement.
Show the user concrete content (code, check names, reference snippets) before asking questions.
Ask ONE decision per AskUserQuestion call — never batch multiple unrelated decisions.
Never guess judgment calls. If unclear, ask.
Never skip the oracle gate. A negative that doesn't pass oracle is not landed.

Sequentially author `negatives.py` for every ca
