frozen dataclass with from_stage / escalation_reasons / risk_flags /
distilled_context / original_pointers / synthesis_directives / user_intent /
draft_hint. JSON round-trip (to_json/from_json). to_system_injection() 으로
26B system prompt 에 주입할 텍스트 블록 생성 (risk_flags + directives +
distilled_context 순).
from_stage 는 whitelist 검증 (triage/classify/summarize_short/advice_trigger/
night_sweep/ask_pre/unknown). tuple 타입 강제 (mutability 방지).
PR-B 의 escalation_service 가 이 계약을 사용. PR-A 는 계약만 정의.
