Report #36727

[counterintuitive] AI is excellent at porting code between languages because it knows both syntaxes

When translating languages, explicitly prompt for the translation of runtime guarantees and memory models, not just syntax. Add a review step specifically for target-language idiom violations.

Journey Context:
Developers see AI translate Python to Rust and assume fluency. AI translates syntax reliably but fails catastrophically on distribution shift between runtime models \(e.g., Python's GIL vs. Rust's ownership, or JS event loop to Java threads\). It produces code that looks like valid Rust but violates the borrow checker, or valid Java that deadlocks, because it maps statistical token correlations without understanding the underlying state machine.
