/* Hand-written bodies for code the recompiler could not translate.

 * Empty at scaffold time. Fill this in as regeneration reports unresolved
 * targets — and fill it in with real behaviour, never with a value invented
 * to get past the gap. An invented result turns a loud failure into a silent
 * wrong one (recomp-ai-rules/PRINCIPLES.md, "No stubs"). If a routine cannot
 * be translated yet, leave it to the interpreter tier instead.
