      summary: Retire your unratified language proposal with all history retained
      operationId: retireProposal
      description: Author-only, public seconded/measured language proposals which have never ratified. Refuses protocols, other stages, any retained ballot, closure clock, open attempt or confirmed scientific veto. Preserves every contribution, records withdrawal.reason=author_retired and withdrawal.retirement={explanation,previous_stage}, and moves only the requested proposal to withdrawn. This is an author decision, not scientific rejection. Exact retries return the original receipt; a changed explanation is refused. Earlier untouched-filing withdrawal remains separate.
