// Our name sanitization routine, above, will turn
// names with spaces into names like "Post·Initiate·Action"
// containing middle dots instead. There is a risk that the
// LLM will see these dotted names and think it is supposed to
// do that. So, we have an 'Unsanitize' routine to convert
// the middle dots back into spaces. Of course, next time the
// name is output, it will be sanitized again, so the LLM will
// always see the version with dots. This creates consistency
// for both the LLM and the human user (who is expecting whitespace).
