a210bf5d52 docs(rag): HOTFIX #15 spec + plan (3 round OMC reviewer approve)
OMC team `hotfix-15-mcp-flaky` 의 spec + plan 작성 + 리뷰 산출물.

- spec: analyst 가 진단 (root cause = PR-7 probe-first 가 PR-5 test 의 stale empty-KB contract 와 mismatch) + Option A 권장 (test-only fix). 3 round review (critic + verifier): CRITICAL C1 (fixture/query FTS5 0 hits) + MAJOR M1/M2 + 등 closure.
- plan: planner 가 7 steps + subagent dispatch task 작성. 3 round review (critic-plan + verifier-plan): empirical SQLite REPL 검증, level-1 dated entry placement, actual KebabHandler/KebabAppState pattern 정합.

implementation = 429287f commit (executor).

98cf4e8a04 chore(release): bump version 0.17.2 → 0.18.0 + cut fb-41 multi-hop
v0.18.0 cut PR. fb-41 multi-hop RAG + NLI verification 의 user-visible surface (PR #176-180) + post-PR9 cleanup/refactor (PR #181) ship 마무리.

## 변경 사항

### Version
- workspace `Cargo.toml`: 0.17.2 → 0.18.0. Cargo.lock 자동 cascade (24 kebab-* crate 모두 0.18.0).

### Frozen design contract
- `docs/superpowers/specs/2026-04-27-kebab-final-form-design.md`:
  - §3.8 RAG types — RefusalReason 에 NliVerificationFailed + NliModelUnavailable + MultiHopDecomposeFailed 추가 + Multi-hop RAG + NLI verification 의 ask_multi_hop facade + step 8.5 NLI hook + HopRecord / VerificationSummary 명시.
  - §9 versioning rules 표 — nli_model_version row 신규 (선택 — v0.19+ second adapter 시 wire surface candidate).

### Status transitions
- `docs/superpowers/specs/2026-05-25-p9-fb-41-finalize-spec.md`: status approved-by-team → completed.
- `docs/superpowers/plans/2026-05-25-p9-fb-41-finalize-plan.md`: status approved-by-team → completed (spec_status 도).

### User-facing docs
- `README.md`: 명령 표의 `kebab ask` row 에 `--multi-hop` flag + NLI 옵션 안내 한 단락 (mDeBERTa-v3 XNLI 280 MB 자동 다운로드 / RAM peak ~7-8 GB / threshold tuning 0.5 prod / 0.0 disable).
- `docs/SMOKE.md`: `[rag] nli_threshold = 0.0` config 예시 + 활성화 절차 + first-run download + RAM 권장 inline 안내.

### Handoff + dashboard
- `HANDOFF.md`: 한 줄 요약 의 현재 version 0.17.2 → 0.18.0. v0.18.0 cut entry 추가 (fb-41 multi-hop + NLI + cleanup ship). Component 카운트 단락에 fb-41 PR-9 의 kebab-nli + ask_multi_hop 추가 명시. 머지 후 결정 절 맨 위에 v0.18.0 fb-41 entry 신규.
- `tasks/INDEX.md`: p9-fb-41  머지 (v0.18.0). v0.18.0 subsection 신규 — PR #176-181 의 6 sub-PR + cleanup 각 한 줄 요약.

## 비범위 / 별 작업
- HOTFIXES.md 의 fb-41 entry 는 이미 PR #180 (PR-9d closure) 에서 작성 완료 — 본 cut PR 에서 추가 anchor 불필요.
- SKILL.md 의 v0.18+ NLI 안내는 이미 PR-9c-2 에서 inline 추가 완료.

## 검증
- `cargo check --workspace -j 1` 통과 (모든 24 crate v0.18.0 확인).
- frozen design 의 RefusalReason enum 확장이 kebab-core 의 production code 와 정합 (PR-9c-1 시점부터 동일 variants 있음).

Wire 영향: 없음 (additive minor 는 PR-9c-1 에서 이미 ship, 본 commit 은 documentation cascade only).
Behavior 영향: 없음.

머지 후 `gitea-release v0.18.0` 으로 tag + release notes 작성.

44fbffff26 docs(rag): fb-41 PR-9 spec + plan — NLI verification + v0.18.0 cut
fb-41 multi-hop RAG 의 dogfood S7 hallucination root cause = LLM-self-judge ceiling.
대응 = NLI-based post-synthesis verification (mDeBERTa-v3 XNLI, 280 MB ONNX).

산출물:

caf690dc72 feat(eval): fb-41 multi-hop golden set + spec/plan
PR-1 of fb-41 multi-hop RAG (spec: docs/superpowers/specs/2026-05-25-
p9-fb-41-multi-hop-rag-design.md, plan: docs/superpowers/plans/2026-
05-25-p9-fb-41-multi-hop-rag.md).

XL 작업의 첫 PR — baseline 측정 anchor 만 추가. RAG pipeline 미변경,
fixture file + parse 회귀 핀.

사용자 결정 4 axis (2026-05-25):
- approach: query decomposition (LLM 서브-질문)
- trigger: explicit `--multi-hop` flag
- MVP scope: dynamic N-hop (LLM 이 depth 결정, decompose seed +
  ReAct-style decide loop hybrid)
- eval: multi-hop golden set 먼저 (본 PR)

본 PR:
- `fixtures/multi_hop_golden.yaml` 신규. 15 question (5 cross-doc +
  5 intra-doc + 5 single-fact negative). 기존 `GoldenQuery` struct
  그대로 사용 — 별 loader / type 변경 없음. `expected_chunk_ids`
  비어 있어 curator 가 `kebab ingest` 후 채울 수 있는 template
  형태. `must_contain` 으로 baseline 측정 가능 (P5-2 metric).
- `crates/kebab-eval/tests/loader.rs::loads_multi_hop_golden_fixture`
  신규 회귀 핀. fixture parse OK + 15 question + 5/5/5 bucket
  분포 + 모든 question 에 must_contain 최소 1 개.

baseline 측정 protocol (별 run, commit 에 artifact 안 포함):
1. v0.17.2 binary 로 single-pass `kebab eval run --fixture
   multi_hop_golden.yaml` 실행
2. P@5, P@10, must_contain pass rate, citation_coverage 캡처
3. PR-3 (dynamic iter 머지) 후 동일 fixture + `multi_hop=true` 로
   재실행 → Δ 비교

PR 분할 6 단계 (plan 참조): PR-1 (본 PR — fixture only), PR-2
(RagPipeline::ask_multi_hop fixed depth=2), PR-3 (dynamic iter),
PR-4 (CLI flag + wire), PR-5 (MCP + SKILL.md), PR-6 (TUI toggle +
trace render). 마지막 PR 후 v0.18.0 cut.

8dcedc4b11 feat(p10-r2): V007 trigram migration + design §5.5 + fts diff-check
Task A2 + A3 한 묶음.

migrations/V007__fts_trigram.sql 신규:
- chunks_fts shadow 를 DROP + 재생성 (tokenize = trigram).
- chunks_ai/ad/au trigger 재생성 (V002 와 동일).
- chunks 에서 backfill INSERT — 사용자 re-ingest 불필요, V007 자동.
- V002 는 historical cold-upgrade replay 위해 그대로 유지.

design §5.5 갱신:
- verbatim block 의 tokenize 만 trigram 으로 교체.
- §5.5 본문 상단에 한국어 채택 사유 + trade-off (영어 lexical 변경,
  BM25 분포, 디스크 ~2-10x, contentless 아님) prose 한 단락 추가.

crates/kebab-store-sqlite/tests/fts.rs:
- fts_v002_matches_design_section_5_5_verbatim →
  fts_v007_matches_design_section_5_5_verbatim 으로 rename.
- extract_migration_5_5_verbatim_block() 의 include_str! path 를
  V007__fts_trigram.sql 로 변경. 주석/assertion msg V007 로.
- V002 cold-upgrade test 들 (fts_v002_backfill_*) 은 그대로 유지.

검증: cargo test -p kebab-store-sqlite --test fts → 10/10 PASS
(`fts_v007_matches_design_section_5_5_verbatim` 포함).

Codex round 1/2 의 design §5.5 contentless 정정·trigram tokenizer
채택 사유 명시 발견 반영.

584247f1ea spec+plan(v0.17.0): korean trigram tokenizer + dogfood fixes
P10 도그푸딩 round 2 (2026-05-22) follow-up. SQLite FTS5 tokenizer
unicode61 → trigram 으로 교체해 한국어 lexical 검색 지원 + 작은
버그픽스 2 (C typedef-wrapped struct 미노출, code_lang_breakdown
집계 단위).

Codex + Gemini round 1/2/3 리뷰 반영:
- [r1] 2자 한국어 query 0-hit, build_match_string() multi-token 깨짐,
  contentless → shadow, parser_version cascade, BM25/heading_path/디스크
- [r2] same-workspace_path orphan purge (parser bump cascade 실제 동작),
  trigram 테스트 예시 sqlite 3.45.1 검증, builder 권장안 (whole phrase OR)
- [r3] SMOKE 시나리오 정정, TUI stale hint 방지, search_response.v1 hint
  필드, new purge helpers, single quote raw mode 통일, fixture 도입

PR 구성: PR-A (trigram + builder + 안내), PR-B (C typedef + orphan
purge), PR-C (stats + wire). 셋 머지 후 v0.17.0 release cut.

7a6a24ad10 feat(p10-1a-2): add MediaType::Code(lang) variant
TDD: red → green cycle confirmed. New `Code(String)` variant serializes
as `{"code":"rust"}` via serde `rename_all = "lowercase"`. All exhaustive
`match` sites updated (`media_label`, `ingest_one_asset` catch-all →
explicit or-pattern). Design §3.5 enum listing synced. Also fix
`/target` symlink gitignore pattern so integration-test binary lookup
via workspace-relative path works with CARGO_TARGET_DIR redirect.

7961f8813d fix(p10-1a-1): PR review round 1 — doc inconsistencies
회차 1 review 의 4 건 actionable 모두 반영:

1. frozen design §2.1 의 code variant 예시에서 존재하지 않는 `repo` 필드 제거 + nested form 에서 actual wire (flat) 형태로 정리. 5 variant 의 nested-form illustrative example 은 그대로 두고, code variant 만 별도 block 으로 분리해서 actual wire 와 1:1 매칭. 또 위쪽 6 variant nested-form group 에서도 'code' 행 삭제 (정확한 contract 는 별도 block 에 있음).
2. §2.2 SearchHit 예시의 `repo: null, code_lang: null` + 'omitted when null' 주석 모순 제거 — 키 자체를 빼고 inline 주석으로 'markdown hit 에는 absent, 코드 hit 에서만 surface' 설명.
3. HANDOFF Phase row 식별자 `**10**` → `**P10**` (다른 row 와 일관성).
4. README synopsis 의 중복 `[--media code]` 제거 (`--media` 는 이미 위쪽에 한 번 있음, code 는 값 중 하나라 prose 에서 설명).

코드 변경 없음 — 모두 markdown 문서.

21 task plan: kebab-core 도메인 타입 (Citation::Code variant, SearchHit repo/code_lang, IngestReport skip counters, Metadata extension), 새 kebab-parse-code crate (lang/repo/skip 모듈, gix dep), kebab-source-fs gitignore+blacklist 통합, kebab-config [ingest.code] 절, kebab-cli --repo/--code-lang flag, wire schema JSON 갱신, frozen design doc 갱신, README/HANDOFF/SMOKE 갱신, task index. 각 task 가 5-step TDD cycle (test fail → impl → pass → commit). 코드 chunker 는 1A-1 에 없음 — 1A-2 에서 추가.

spec 의 Citation::Code 예시가 기존 5 variants 의 flat wire 형태와 안 맞아서 (`code: {...}` 중첩이 아니라 top-level field) 같이 fix.

Tier 1 (Rust/Python/TS-JS/Go/Java/Kotlin/C/C++) 은 tree-sitter AST per-language chunker, Tier 2 (k8s manifest / Dockerfile / Cargo.toml 류) 는 resource-aware chunker, Tier 3 (shell / fallback) 는 paragraph + line-window. embedding 은 multilingual-e5-large 유지 — cross-corpus 검색 위해. Phase 1A (Rust) 부터 1D (C/C++) + Phase 2 (Tier 2) + Phase 3 (Tier 3) 순으로 진행. ignore 통합 (.gitignore honor + .kebabignore 추가 + 최소 built-in safety net), generated header sniff, size cap 으로 첫 도그푸딩 비용 차단. 새 Citation variant `code`, SearchHit 의 repo/code_lang 필드, --media code / --code-lang / --repo filter — 모두 additive minor.

7dddc1d706 fix(fb-35): address PR #126 round 1 review
- fetch_span: panic-fix on line_start > total / empty doc
  (return empty text + effective_end = line_start - 1 instead of
  out-of-bounds slice)
- truncated: reserved for budget-driven truncation only; line
  range clamp signaled via effective_end < line_end
- spec / SKILL.md / README: align rejection wording to "PDF /
  audio" (matches code; Image OCR allowed for span)
- store: warning comment on list_chunk_ids_for_doc — chunk_id
  hash sort does NOT preserve document position; real fix is a
  chunks.ordinal column, tracked as follow-up
- surrounding_chunks: saturating_add to defend against u32::MAX
  context arg on 32-bit targets
- tests: line_start > total returns empty + chunk context at
  doc boundary clamps lower bound

Deferred nits (follow-up): table-separator strict CommonMark form;
MCP per-mode strict validation; CLI chunk_id truncation in plain
output. None block correctness.

신규 명령 `kebab ingest-file` + `kebab ingest-stdin` + MCP tool
`ingest_file` + `ingest_stdin` 도입 brainstorm 산출물. agent fetch 한
web markdown / 단일 외부 file 을 KB 에 즉시 저장.

핵심 결정:
- 외부 file 저장: copy in (`<workspace.root>/_external/<hash12>.<ext>`).
  blake3 content hash 기반 deterministic 명명 → idempotent.
- CLI: 신규 subcommand 2개 (기존 `kebab ingest` 무영향).
- MCP: 4 → 6 tool. fb-30 v1 read-only 정책 변경 — 첫 mutation tool
  surface (의도된 진화).
- .kebabignore: explicit ingest 가 default bypass + stderr warn.
- stdin v1: markdown 전용 + flag (--title, --source-uri) → frontmatter
  자동 prepend. 이미 frontmatter 있으면 error (use ingest-file).
- `_external/` 디렉토리 첫 생성 시 .kebabignore 자동 append (walk
  re-ingestion 무한 루프 방지).
- source_uri 는 frontmatter → Document.metadata 자동 흐름. wire
  schema 변경 없음 (ingest_report.v1 / search_hit.v1 의 metadata
  free-form map 재사용).

릴리스: 0.3.1 → 0.3.2 patch — additive only.

`kebab mcp` 신규 subcommand + new crate `kebab-mcp` 도입을 위한
brainstorm 산출물. agent integration "MVP" 완성 (Claude Code / Cursor /
OpenAI Agents 등 host-agnostic 사용 가능).

핵심 결정:
- `kebab mcp` subcommand (kebab-cli 내, 신규 binary 아님)
- 4 read-only tool (`search` / `ask` / `schema` / `doctor`) — ingest /
  fetch / list_docs / inspect_chunk 는 fb-31 / fb-35 / 후속에서 추가
- Resources / Prompts 모두 skip (tools only)
- Rust MCP SDK 사용 — rmcp 채택 우선, plan 단계 verify
- stdio 단일 transport — fb-29 deferral 따라 HTTP-SSE P+
- error mapping: tool dispatch 실패만 isError=true + error.v1 content,
  refusal / no-hit / unhealthy 는 정상 응답 (semantic flag 으로 분기)
- classify 모듈 이전: kebab-cli::error_classify → kebab-app::error_wire
  (kebab-cli + kebab-mcp 둘 다 동일 모듈 사용, facade 룰 준수)
- capability flag `mcp_server` false → true

릴리스: 0.3.0 → 0.4.0 minor — 신규 surface + new crate + 디자인 §10.1
변경 + capability flip 모두 trigger.

`kebab schema` 신규 명령 + `error.v1` wire schema 도입을 위한 brainstorm
산출물. agent 통합 (fb-30 MCP, fb-29 daemon) 의 prerequisite — 한 번의
introspection 호출로 wire 버전 / capabilities / model versions / index
stats 를 노출하고, fatal error 가 `--json` 모드에서 stderr ndjson 으로
구조화된다.

핵심 결정:
- `kebab schema --json` 단일 명령 (정적 + 동적 통합)
- error.v1 emission 은 `--json` 모드에서만 — 비 `--json` 은 기존 stderr text 유지
- exit code 0/1/2/3 unchanged, error.v1.code 가 fine-grained 분기
- 7 code initial set (config_invalid / not_indexed / model_unreachable /
  model_not_pulled / timeout / io_error / generic) + future-additive 정책

40ca4bf27e spec(p9-fb-25): config workspace.include 제거 + 지원 형식 가시성
도그푸딩 피드백 2026-05-05:
1. config 의 include + exclude 동시 존재가 case 4 (둘 다 매치 안 함)
   에서 의미 모호.
2. 어차피 처리 가능 형식 (md / png / jpg / pdf) 이 정해져 있으니
   사용자에게 명시 필요.

설계 핵심:

- `WorkspaceCfg.include: Vec<String>` 제거 (denylist-only). 옛 config
  의 `include = [...]` 은 silently 무시 + Config::load 가 단발
  deprecation warning emit.
- `IngestItem.warnings` 에 skip 사유 채움 (`unsupported media type:
  .docx` / `kb:// URI not yet supported`).
- `IngestReport.skipped_by_extension: BTreeMap<String, u32>` 신규
  (additive wire — release 트리거 안 됨 per CLAUDE.md). key =
  lowercase ext (`docx`, `txt`), no-ext = `<no-ext>` sentinel.
- CLI / TUI summary 에 breakdown 표시 (`90 skipped: 80 docx, 5 txt,
  5 epub`) — 모두, desc 정렬.
- README + `kebab init` config.toml 주석에 지원 형식 명시.

Spec status `planned`. 다음 단계: writing-plans skill 로 implementation
plan 작성.

ddec3d8a94 spec(p9-fb-23): incremental ingest — skip unchanged docs
도그푸딩 피드백: 변경/신규 doc 만 ingest, 변하지 않은 문서는 skip.

설계 핵심:

- Skip 조건 4 개 (full version cascade): blake3 checksum + parser_version
  + chunker_version + embedding_version 모두 일치 시 parse/chunk/embed/
  vector upsert 회피. 비용 dominator (fastembed) 가 변경된 / 새 doc 에만.
- SQLite V006 migration — `documents` 에 `last_chunker_version` +
  `last_embedding_version` column 추가. 기존 row NULL → 첫 ingest 강제
  재처리 (안전 default).
- `IngestItemKind::Unchanged` enum variant 신규 (기존 `Skipped` 와
  의미 분리 — `Skipped` 는 media-type 필터, `Unchanged` 는 모든 versions
  match).
- `IngestReport` + `AggregateCounts` 에 `unchanged: u32` 필드 추가.
  wire schema additive — v1 호환 유지.
- `--force-reingest` flag — skip 무시하고 강제 재처리.
- TUI status_line final 에 `unchanged=N` 노출 (p9-fb-24 status bar
  dynamic slot 자동 cascade).

Spec status `planned`. 다음 단계: writing-plans skill 로 implementation
plan 작성.

모든 모드에서 항상 떠 있는 상태바 + 키 안내바 + 버전 정보) 을 단일
spec 으로 묶음.

설계 핵심:

- bottom 영역을 2 row 로 분할: 윗줄 = 상태바 (`kebab v0.1.0 │ pane │
  doc_count │ 동적 상태`), 아랫줄 = 기존 footer_hints 그대로 이전.
- ingest progress 의 dedicated row 를 status bar 의 동적 영역으로 흡수
  (시각적 source 단일화).
- Library `List` 위에 `format_doc_header` 헤더 row 추가 (TITLE / TAGS
  / UPDATED / CHUNKS, display-width 정렬, Role::Heading).
- Ask + Inspect 양쪽에 PgUp/PgDn (fixed step 10). Ask 는 j/k 와 동일
  하게 follow_tail = false 로 freeze.

p9-fb-13 (footer 단행 row) + p9-fb-03 (ingest dedicated row) frozen

c97e8e00ef feat(kebab-core + kebab-store-sqlite): p9-fb-17 chat session storage (V005)
도그푸딩 item 13/14 (multi-turn 영속화) — TUI Ask 의 "이전 대화
이어가기" + 향후 CLI `--session foo` (p9-fb-18) backing store. session
header + per-turn 두 테이블, ON DELETE CASCADE 로 reset --data-only 가
한꺼번에 wipe.

## 핵심 변경

- **SQLite V005 migration** `chat_sessions` (session_id PK + created_at
  + updated_at + title + config_snapshot_json) + `chat_turns` (turn_id
  PK + session_id FK ON DELETE CASCADE + turn_index + question +
  answer + citations_json + created_at + UNIQUE(session_id, turn_index))
  + `idx_chat_turns_session(session_id, turn_index)`. 모두 `STRICT`.
- **`kebab_core::ChatSessionRepo`** trait (6 method): create_session /
  get_session / list_sessions(limit, ORDER BY updated_at DESC) /
  delete_session / append_turn / list_turns(ORDER BY turn_index ASC)
- **`kebab_core::{ChatSessionRow, ChatTurnRow}`** structs — Serialize
  + Deserialize 둘 다 (CLI / wire 출력 호환)
- **`kebab-store-sqlite::SqliteStore`** impl 신규 모듈 `chat_sessions.rs`.
  `append_turn` 이 insert + parent updated_at bump 같은 connection
  에서 처리.
- **frozen design §5** 에 §5.7a chat_sessions / chat_turns 절 신설
  (full schema + trait 메서드 6 개 명시).

## HOTFIXES (V004 → V005)

spec p9-fb-17 의 `V004__chat_sessions.sql` 가 p9-fb-19 의
`V004__kv.sql` (이미 머지) 와 refinery migration number 충돌. 무중단
정정: `V005__chat_sessions.sql` 로 시프트. schema / 동작 동일, 파일명
만 이동. HOTFIXES entry 추가.

## 테스트

- 9 신규 integration unit (create/get roundtrip, missing→None, PK
  collision error, append+list ordered, dup turn_index error,
  append bumps updated_at, delete CASCADE turns, list_sessions
  ORDER BY updated_at DESC, list_sessions LIMIT)
- workspace 전체 `cargo test --workspace --no-fail-fast -j 1` exit 0
- `cargo clippy --workspace --all-targets -- -D warnings` clean

## 문서

- frozen design §5.7a 신설
- HANDOFF: 2026-05-03 entry
- HOTFIXES: V004 → V005 rename rationale
- spec status planned → in_progress

## Out of scope

- session 검색 / 필터 UI (p9-fb-18 의 `kebab ask --session list`
  같은 admin command 가 후속)
- 다른 store backend (postgres 등) — trait 만 정의, impl 은 SQLite

unblocks p9-fb-18 (CLI session/repl).

0e408fb1b5 feat(kebab-app + kebab-store-sqlite): p9-fb-19 search LRU cache + corpus_revision
도그푸딩 item 15 — TUI / 같은 process 안에서 동일 query 반복 시 SQLite
FTS + Lance + RRF 재계산이 매번 발생하던 비용 해소. in-process LRU
캐시 + 모노토닉 corpus_revision 카운터로 ingest commit 발생 시 모든
entry 자동 stale.

## 핵심 변경

- **SQLite V004 migration**: `kv (key TEXT PRIMARY KEY, value TEXT)
  STRICT` + `corpus_revision = '0'` seed. 미래의 다른 scalar 도 같은
  테이블에 들어갈 수 있는 generic shape.
- **`SqliteStore::corpus_revision()` / `bump_corpus_revision()`** —
  `UPDATE ... CAST AS INTEGER + 1` atomic. INSERT-OR-IGNORE 도 함께
  실행 (V004 seed 가 무슨 이유로 누락된 케이스 paranoid).
- **`kebab-app::ingest_with_config_cancellable`** — `new + updated > 0`
  시 bump, no-op (skipped-only) reingest 는 cache 보존.
- **`App.search_cache: Option<Mutex<LruCache<SearchCacheKey, Vec<
  SearchHit>>>>`** — `config.search.cache_capacity` (default 256, 0
  비활성). `lru = "0.12"` workspace dep 추가.
- **`SearchCacheKey`** = `query_norm` (NFKC + trim + lowercase) +
  `mode` + `k` + `snippet_chars` + `embedding_version` (vector/hybrid
  만, lexical 은 빈 문자열) + `chunker_version` + `corpus_revision`
  snapshot.
- **`App::search`** rewrite — cache 활성 시 lookup → miss 면 기존
  `search_uncached` 호출 후 put. cache 비활성이거나 lock 실패면
  straight-line.
- **`App::search_uncached`** (rename of pre-fb-19 `search` body) +
  `search_uncached_with_config` facade — CLI `kebab search --no-cache`
  로 진입.
- **`Config.search.cache_capacity: usize`** field, `#[serde(default)]`
  로 기존 config 호환.
- **CLI `--no-cache`** flag — 디버깅용 (CLI 는 매 호출이 새 process
  라 사실상 no-op 이지만 spec 명시 + 향후 long-lived process 호환).
- **frozen design §9 versioning** 표에 `corpus_revision` row 추가
  (기존 `index_version` 라벨과 다른 차원: 라벨은 retrieval 형상,
  corpus_revision 은 ingest commit ack).

## 테스트

- `kebab-store-sqlite` 신규 3 unit (fresh=0, monotonic bump, persist
  across reopen)
- `kebab-app` 신규 4 integration (cached repeat 같은 hits, NFKC 정규화
  로 case/whitespace collapse, --no-cache parity, first ingest bumps
  corpus_revision)
- 워크스페이스 전체 `cargo test --workspace --no-fail-fast -j 1` exit 0
- `cargo clippy --workspace --all-targets -- -D warnings` clean

## 문서

- README `kebab search` 행: 캐시 동작 + `--no-cache` 안내 + corpus_
  revision 무효화 메커니즘
- docs/SMOKE.md `[search]` 절에 `cache_capacity` 라인 추가
- HANDOFF: 2026-05-03 entry
- spec status planned → in_progress

## Out of scope

- patch-and-merge incremental (RRF 정규화 전체 hit set 기준이라 어려움)
- SQLite 영속 cache (P+)
- 다른 process 간 cache 공유 (in-process 만 — corpus_revision 이
  cross-process 무효화는 O(1))
