Transmute

Transform a single function, module, or data structure from one form to another while preserving its essential behavior. Lighter-weight than the full athanor cycle, suitable for targeted conversions where the input and output forms are well-understood. Use when converting a function between languages, shifting a module between paradigms, migrating an API consumer to a new version, converting data formats, or replacing a dependency — when the transformation scope is a single function, class, or module rather than a full system.
