[counterintuitive] Can AI reliably refactor and simplify complex nested logic?

When asking AI to refactor logic, explicitly specify: 'Preserve all short-circuit evaluations and side-effect ordering. Do not change execution state.'

Journey Context:
Humans view refactoring as preserving external behavior while changing internal structure. LLMs view refactoring as maximizing readability and minimizing token count. AI will frequently reorder function calls, remove 'redundant' variables that actually cache side-effects, or break short-circuit evaluation \(e.g., changing \`a && b\` to \`if\(a\) b\` but altering the evaluation context\). The code looks cleaner, but the execution state has silently changed.
