feat(rag): fb-41 PR-9c-2 — pipeline integration + mock test + SKILL.md (★ NLI 실 활성화)
PR-9c-1 의 wire surface 위에 behavior 활성화 — `ask_multi_hop` 의 step 8.5 hook 가 `[rag] nli_threshold > 0` 일 때 NLI 검증 실 수행. **첫 user-visible behavior change** in PR-9.
- crates/kebab-rag/src/pipeline.rs:
- ask_multi_hop step 8.5 NLI hook (empty answer 가드 + truncate_for_nli + verifier.score + verification field + refusal 분기).
- refuse_nli_verification helper (verification: Some(...) + RefusalReason::NliVerificationFailed).
- refuse_nli_model_unavailable helper (verification: None + RefusalReason::NliModelUnavailable).
- truncate_for_nli helper (module-level pub fn, MAX_NLI_PREMISE_CHARS = 4 * 400 = 1600 chars 의 chars-based budget, _hypothesis 미사용 placeholder — v0.18.1 token-budget 갱신 candidate).
- PR-9c-1 의 #[allow(dead_code)] 두 곳 제거 (verifier field + with_verifier builder; doc 의 transitional sentence 도 정리). round-1 PR-9c-1 review N1 carry-forward closure.
- crates/kebab-app/src/app.rs:
- App::open_with_config 의 NliVerifier construction — config.rag.nli_threshold > 0 → OnnxNliVerifier::new + Arc::new wrap + 후속 RagPipeline 초기화 시 with_verifier 호출. 실패 시 ? 전파 (시그니처 Result<Self> 그대로 — caller cascading 0).
- kebab-app/Cargo.toml 에 kebab-nli path 의존 추가.
- crates/kebab-rag/tests/multi_hop.rs + tests/common/mod.rs:
- MockNliVerifier (pass / fail / err 생성자 + score call_count instrumented).
- multi_hop_nli_pass_keeps_grounded — entailment 0.9 → grounded=true, verification.nli_passed=true.
- multi_hop_nli_fail_refuses — entailment 0.1 → refusal=NliVerificationFailed.
- multi_hop_nli_disabled_skip_verify — threshold 0.0 → verify skip, verification=None.
- multi_hop_nli_model_unavailable_refuses — verifier Err → refusal=NliModelUnavailable.
- multi_hop_truncate_for_nli_preserves_hypothesis — long premise truncation + hypothesis 보전.
- integrations/claude-code/kebab/SKILL.md: mcp__kebab__ask 절에 NLI 안내 한 단락 (verification.nli_passed 의미 + threshold tuning + nli_verification_failed/nli_model_unavailable refusal handling).
검증: cargo test --workspace -j 1 — 5 신규 multi-hop pass + 회귀 0 (pre-existing kebab-mcp::tools_call_ask_multi_hop 동일 flaky). cargo clippy --workspace --all-targets -j 1 -- -D warnings clean.
Wire 영향: PR-9c-1 의 schema 변경에 *behavior wiring* — answer.v1.verification field 가 multi-hop happy path + refuse path 양쪽에서 채움.
