v0.17.0 trigram tokenizer entry 가 미수정으로 남겨둔
heading_path_json JSON 노이즈 (HOTFIXES 2026-05-24) closure.
trigram 이 chunks_fts.heading_path 컬럼 (V002/V007 트리거가
chunks.heading_path_json 그대로 INSERT) 의 JSON 표기 + 안의 path
세그먼트 (app, src) 까지 3-gram 색인해서 query 가 우연히 false
positive hit 하는 문제. column filter 채택 — heading 색인 유지
(V007 verbatim 불변), 매칭 대상만 text 컬럼 한정.
- build_match_string 가 non-raw 분기에서 combined expression 을
`text : (<expr>)` 로 wrap. FTS5 column filter syntax 가 OR/AND
sub-expression 허용.
- Raw mode (`'...'`) 는 그대로 — 사용자가 명시 의도로
`'heading_path : agent'` 같은 explicit opt-in 가능 (escape hatch).
- 8 기존 build_match_string unit test expected string 갱신 +
`build_match_string_raw_mode_preserves_heading_filter` 신규.
- `lexical_heading_only_token_does_not_hit_default_mode` 신규 회귀 핀
(heading-only unique token 이 default mode 에서 0 hit).
- `lexical_raw_mode_can_opt_into_heading_path_filter` 신규 — 같은
fixture 가 raw mode 로 hit 확인 (escape hatch 동작 핀).
사용자 영향: lexical / hybrid 검색의 본문 precision ↑. recall
변화 없음 (text 본문 token 매칭은 동일). re-ingest 불필요 (FTS
query 시점 매칭만 변경). lexical_snapshot_run_1 + hybrid_snapshot
도 fixture regenerate 불필요 (text 본문 매칭 query 라 BM25 동일).
HOTFIXES: 2026-05-24 v0.17.0 entry 의 `heading_path_json` 노이즈
항목 closure 표기 + 새 2026-05-25 post-v0.17.1 dogfood entry 추가.

p10-1A-1 (PR #139) added SearchFilters.code_lang + .repo fields and the CLI
--code-lang / --repo flags propagate them correctly into SearchFilters, but
neither the lexical retriever's FTS SQL nor the shared filter_chunks helper
(used by the vector retriever) ever applied them — so a code-lang-filtered
search returned all-doc hits (markdown / pdf / code mixed).
Discovered while dogfooding p10-1B with httpx + zod + lodash clones:
`kebab search 'AsyncClient' --code-lang python --json` returned markdown
hits from httpx/docs/ first.
Fix: add IN-list filters on json_extract(d.metadata_json, '$.code_lang')
and '$.repo' to both lexical.rs and filters.rs, mirroring the existing
media filter pattern. Two regression tests added in each crate covering
the new filter behavior.

- Add ScoreKind::Bm25 to LexicalRetriever::build_hit SearchHit construction
- Import ScoreKind from kebab_core in lexical.rs
- Add integration test lexical_retriever_hits_carry_bm25_score_kind to verify all
hits from LexicalRetriever carry score_kind == ScoreKind::Bm25
- Update lexical snapshot test baseline to include new score_kind field

SQL WHERE clause extension. media uses CASE WHEN json_type='text'
to handle both unit (\`"markdown"\`) and tuple (\`{"image":"png"}\`)
MediaType serde shapes. ingested_after relies on RFC3339 lexicographic
ordering with UTC Z (per fb-32 ingest invariant). doc_id is a simple
equality. AND combinator with existing tags / lang / trust filters.
