Function target_not_designated 

pub fn target_not_designated() -> String

GAP-SG-207: a subcommand that changes durable state reached path resolution without naming its target in the argv.

Names both ways out, because a refusal that only states a verdict leaves the operator guessing: designate the target, or accept the ambient one on purpose. The flag spellings stay English in both languages, since they are what the caller must type.
