//! `hwpforge_stamp_plan` / `hwpforge_stamp` — 산문 placeholder 를 이름 붙은
//! 누름틀로 승격하는 템플릿 스탬핑 (E6, 2단계 plan/apply).
//!
//! plan 은 클래스-A 후보를 나열하고, 호출자가 후보 전량을 이름 또는 ignore
//! 로 분류한 spec 배열을 stamp 에 전달한다. stamp 는 fail-closed admission
//! 게이트(무손실 왕복 + ZIP closed-world) 뒤에서 all-or-nothing 으로
//! 적용하고 manifest 를 함께 기록한다.
