docs(search): passage-RAG go/no-go = NO-GO (hier evidence 동등, diagnose c4+c5)

PR-DocSrv-Hier-PassageRAG-Diagnose-1 c4+c5. 조건부 N=12(retrieval 통제) blind pairwise
(hypothesis-blind subagent, 익명 3-file split). 결과 4-way 수렴 = 동등:
pairwise prehier4/hier3/tie5(no edge) + axis ±0.08 + objective 동일(halluc36/36) +
variance~0(byte-identical 재생성). verbosity artifact 없음(prehier 더 길었으나 승+1).
=> NO-GO: hier-leaf evidence 무이득. hier leaf = section-outline UI 전용 완전 확정
(UI yes / doc-search NO-GO / passage-RAG NO-GO 3영역 종결). 2026-06-21 freeze input only.
