a58ee10dfb fix(parse-pdf): strip Identity-H Unimplemented marker + dominance heuristic in compute_valid_char_ratio (Bug #6)
Why: metro-korea.pdf (Identity-H CID font without ToUnicode CMap) 의
ingest 가 pdf_ocr_pages=0 으로 잘못 종료. lopdf 0.32.0 의 emit
`?Identity-H Unimplemented?` marker 28 ASCII char 가 is_valid_text_char()
의 0x0020..=0x007E range 통과 → ratio=1.0 → OCR fallback 0.5
threshold bypass.

Change: MOJIBAKE_MARKERS const + compute_valid_char_ratio() 4-단계
(strip → trim-empty zero → dominance cap-0.3 → 기존 ratio). marker
list extensible. is_valid_text_char() 본체 변경 0.

Tests: +2 unit (dominance + minority) on top of 기존 8. parser_version
/ wire schema 변경 0.

e674ff474b fix(parse-pdf): F4 mojibake.pdf via pikepdf surgery; preserve 1-page invariant (Bug #4)
v0.20.0 sub-item 1 dogfood report 의 Bug #4 — F4 mojibake.pdf 의 lopdf
`get_pages()` count = 0 (Pages tree broken). root cause = 기존 byte-
level `re.sub` + manual startxref edit 가 lopdf strict load 통과시키지만
Pages dict 의 `/Kids` reference 깨짐.

- `tests/fixtures/_synth/mojibake.py`: full rewrite — replace byte-level
  `re.sub` + manual startxref with pikepdf open+inject-dummy-ToUnicode+
  del+save (auto xref regen). HYSMyeongJo-Medium CID font: CID font 이
  ToUnicode 를 자체 생성하지 않아 dummy stream 을 inject 후 strip
  (removed=1 invariant). Exit codes 2/3/4 for invariant fail.
- `crates/kebab-parse-pdf/tests/fixtures/mojibake.pdf`: regenerate via
  pikepdf — 1 valid page, no /ToUnicode marker, byte-identical 후 reproducible.
- `crates/kebab-parse-pdf/tests/snapshots/vector_pdf_canonical.json`:
  regen via 2-run cargo test pattern (hand-rolled unwrap_or_else baseline
  bootstrap, no insta crate).
- `crates/kebab-parse-pdf/tests/text_extractor_regression.rs`: append 3
  invariant test — (1) lopdf 1-page, (2) /ToUnicode marker absent,
  (3) PdfTextExtractor 1-block invariant.
- `crates/kebab-parse-pdf/src/text_quality.rs`: f4_fixture_ratio_under_threshold
  threshold 0.3 → 0.5 (production valid_ratio_threshold 기본값). 구 broken
  fixture (pages=0) 는 extract_text="" → ratio=0.0; 신 fixed fixture 는
  CID 2-byte fallback decode → ratio≈0.375 — 여전히 OCR trigger 조건 충족.

48197687b7 test(pdf): integration smoke (w/ search + cancel) + vector regression + alnum e2e (#[ignore]) for v0.20 sub-item 1
Step 9 (Group I) of v0.20.0 sub-item 1 (scanned PDF OCR) plan.

I3 — crates/kebab-app/tests/ingest_pdf_ocr_smoke.rs (신규):
- ingest_with_mock_ocr_yields_pdf_ocr_summary — `#[ignore]` real Ollama,
  ingest_with_config production path + IngestItem.pdf_ocr_pages verify.
- ocr_text_indexed_and_searchable — `#[ignore]` real Ollama, app.search
  의 OCR text indexed verify (§ Acceptance #2).
- ingest_with_cancel_aborts_mid_pdf — production cancel chain (pre-set
  cancel=true + dummy endpoint, no panic/deadlock verify).

I4 — crates/kebab-parse-pdf/tests/text_extractor_regression.rs (신규):
- vector_pdf_extract_byte_identical_to_baseline — F4 mojibake.pdf 의 vector
  PDF path canonical 의 byte-identical 보존 (Step 1-8 모든 변경 전후 invariant).
- baseline 신규 = tests/snapshots/vector_pdf_canonical.json (first run create).
- normalize_provenance_timestamps inline helper (R-3 mitigation, workspace
  전체 부재 — 신규 12-line).

I5 — crates/kebab-parse-pdf/tests/ocr_e2e.rs (신규):
- f1_alnum_accuracy_ge_85 / f2_alnum_accuracy_ge_70 — `#[ignore]` real
  Ollama qwen2.5vl:3b, § Acceptance §9 #3 의 implementation.
- alnum metric = strsim::levenshtein (dev-dep 추가).
- truth file copy from PoC scratch (page1.txt + page2-batchim.txt) →
  scanned_page1_truth.txt + scanned_page2_truth.txt.
- kebab-parse-image dev-dep 추가 (OllamaVisionOcr::from_parts 호출용).
  parser isolation invariant 의 dev-dep exception (spec §3.1, dep graph
  baseline -e normal 보존).

b9ee09f176 feat(app): wire PDF OCR enrichment + cancel propagation into ingest_one_pdf_asset (H-5 eager init + post-extract hook + per-page cancel) + workspace lopdf dep (Step 4 M-4)
Step 6 (Group E) of v0.20.0 sub-item 1 (scanned PDF OCR) plan +
Step 7 spillover (IngestEvent variant + IngestItem field for compile
boundary) + Step 4 reviewer Minor M-4 fix.

E1 — eager PDF OCR engine build at `ingest_with_config_opts` entry,
mirror of image OCR pattern (lib.rs:338-347). `pdf.ocr.enabled ||
always_on` 시 `OllamaVisionOcr::from_parts(endpoint, model, ...)` 호출
+ fail-fast `?`. App field 추가 0 (local var only, spec L-1 / Step 1
A1 cosmetic fix 정합).

E2 — `ingest_one_pdf_asset` signature extension: +3 param
(`pdf_ocr_engine: Option<&OllamaVisionOcr>`, `progress: Option<&
mpsc::Sender<IngestEvent>>`, `cancel: Option<&Arc<AtomicBool>>`).
`ingest_one_asset` dispatch wrapper + caller (dispatch loop) update.

E3 — post-extract enrichment block at `extract_for` 직후 (line 1779).
`pdf.ocr.enabled || always_on` 시 `apply_ocr_to_pdf_pages` 호출,
PdfOcrProgress → IngestEvent emit (PdfOcrStarted / PdfOcrFinished
with ocr_engine), summary 의 pages_ocrd/ms_total 을 IngestItem field
로 carry. PR #187 registry dispatch invariant 보존
(`extract_for(&asset.media_type, ...)` 그대로).

E4 — cancel handle propagation: ingest_with_config_cancellable →
IngestOpts.cancel → ingest_with_config_opts → ingest_one_asset →
ingest_one_pdf_asset (new `cancel` param) → PdfOcrOpts.cancel chain.
spec §4.8 line 1159 production wiring.

Step 7 spillover (compile boundary):
- `kebab_app::ingest_progress::IngestEvent`: PdfOcrStarted { page } +
  PdfOcrFinished { page, ms, chars, ocr_engine }. serde discriminant
  `pdf_ocr_started` / `pdf_ocr_finished` (Step 7 G3 wire schema 와 일치).
- `kebab_core::IngestItem`: pdf_ocr_pages: Option<u32> +
  pdf_ocr_ms_total: Option<u64> (warnings/error 사이). 11 non-PDF
  IngestItem construct site 가 `None` 채움.
- `kebab-cli/src/progress.rs` + `kebab-tui/src/ingest_progress.rs`:
  새 variant no-op handler (v1에서 per-page progress 미노출, future
  refinement 시 활성화 가능).
- `kebab-store-sqlite/tests/ingest_report_snapshot.rs` + snapshot
  `ingest_report.snapshot.json`: 2 IngestItem fixture 의 새 field 추가.
- Step 7 의 JSON Schema 갱신 + CLI printer activation + snapshot
  regenerate 는 별 commit (G3/H1/H2 deliverable).

M-4 (Step 4 reviewer Minor) — lopdf workspace dep 통합:
- workspace `Cargo.toml [workspace.dependencies] lopdf = "0.32"`.
- kebab-app + kebab-parse-pdf 의 direct dep → `{ workspace = true }`.

Verifier evidence:
- workspace test (`cargo test --workspace --no-fail-fast -j 1`):
  175 test result summary lines, 0 failures, 0 FAILED.
- workspace clippy (`-D warnings`): exit 0, 0 warning.
- dep graph baseline (`.omc/state/pdf-ocr-{parse-pdf,app-parse}-deps.baseline.txt`):
  empty diff for both.

8d81bc1071 style(parse-pdf): satisfy clippy pedantic in page_image (uninlined_format_args + map_unwrap_or)
c2cd3a7 의 `extract_dctdecode_page_image` 에 workspace clippy pedantic 위반 2 건
잔존 → CI gate (cargo clippy --workspace --all-targets -- -D warnings) fail.
두 lint 모두 1-line edit + semantic 동일, logic 변경 0.

- L20  uninlined_format_args: format!("page {} not in get_pages()", page_num)
                              → format!("page {page_num} not in get_pages()")

                              → .is_some_and(|n| n == b"Image")

cargo clippy --workspace --all-targets -j 4 -- -D warnings → exit 0.
cargo test -p kebab-parse-pdf -j 4 → 21 passed (regression 0).

c2cd3a7ab7 feat(parse-pdf): add page_image (DCTDecode passthrough, 2 test) + text_quality (valid char ratio, 8 unit test) modules
Step 3 (Group C) of v0.20.0 sub-item 1 (scanned PDF OCR) plan.

C1 — `page_image::extract_dctdecode_page_image(pdf_doc, page_num)` ->
Result<Option<Vec<u8>>>. lopdf 의 Resources/XObject traverse, 첫 image
XObject 의 /Filter 검사 (single Name OR Array form 모두 cover, spec §4.1
line 642-664), DCTDecode + JPEG magic 검증 통과 시 raw bytes 반환. 다른
encoding 또는 image XObject 부재 시 Ok(None). v1 scope = DCTDecode
passthrough only (H-3 invariant, image crate 도입 0).

Integration test (`tests/page_image.rs`, 2 test):
- f1_fixture_yields_dctdecode_jpeg_bytes — F1 fixture happy path.
- flate_raw_fixture_yields_none — F6 fixture negative path.

C2 — `text_quality::compute_valid_char_ratio(s) -> f32`. valid char =
ASCII printable + Hangul (Jamo/Compatibility/Syllables) + CJK + Latin
Extended + common Korean punctuation. 빈 string → 0.0. caller
(`kebab-app::pdf_ocr_apply`) 가 threshold 와 비교 (default 0.5).

Unit test (`mod tests`, 7 + F4 conditional):
- empty / pure ASCII / pure Hangul / pure PUA / mixed half / CJK / Hangul Jamo.
- f4_fixture_ratio_under_threshold: active (case A — lopdf extract_text 가
  ToUnicode CMap 부재 시 빈 string 반환 → valid_ratio = 0.0000 < 0.3).

Also: Cargo.toml description 갱신 ("Text PDF extractor + scanned-page
image extract helpers ...", Step 1 A2 이연분).

fixture fix: mojibake.pdf 의 startxref 22130 → 22114 (16-byte offset 오차
수정 — lopdf strict parser 가 xref 를 찾지 못하는 버그 해결).

aeeff3635b poc+test(pdf-ocr): lopdf /Filter probe + 5 fixture commit (F1/F2/F4/F6/F7) for v0.20 sub-item 1
Step 2 (Group B) of v0.20.0 sub-item 1 (scanned PDF OCR) plan.

B1 — lopdf /Filter probe (Python re + shell grep on synthesized fixtures,
result appended to docs/superpowers/poc/2026-05-27-pdf-ocr-engine-comparison.md).

Key findings:
- reportlab default (useA85=1) yields /Filter [ /ASCII85Decode /DCTDecode ];
  useA85=0 gives pure /Filter [ /DCTDecode ] with JPEG magic ffd8ffe0.
- Pillow RGB.save('.pdf','PDF') uses DCTDecode — F6 FlateDecode requires
  manual PDF construction via zlib.compress.
- ghostscript pdfwrite rejects TIFF input (/undefined in II*) —
  ImageMagick `convert -compress Group4` used for F7 CCITTFax.

B2 — 5 fixture 합성·commit under crates/kebab-parse-pdf/tests/fixtures/:
- F1 scanned_page1.pdf — /Filter [ /DCTDecode ], JPEG magic ffd8ffe0 (page1-clean.png, 한국어).
- F2 scanned_page2.pdf — /Filter [ /DCTDecode ], JPEG magic ffd8ffe0 (page2-clean.png, 받침).
- F4 mojibake.pdf       — DejaVu TTF + ToUnicode CMap stripped (count=0);
                          Noto CJK TTC has PostScript outlines unsupported by reportlab.
- F6 flate_raw.pdf      — /Filter /FlateDecode, DCTDecode absent (skip path input).
- F7 ccitt.pdf          — /Filter [ /CCITTFaxDecode ], DCTDecode absent (skip path input).

Synth scripts under tests/fixtures/_synth/:
- scanned_pdf.py    — F1/F2 reportlab drawImage + JPEG passthrough (useA85=0).
- mojibake.py       — F4 reportlab DejaVu TTF + ToUnicode strip.
- flate_ccittfax.sh — F6 manual zlib PDF + F7 Pillow TIFF group4 + ImageMagick convert.

7c85de065a chore: workspace-wide cleanup — clippy::pedantic baseline + auto-fix
cut PR v0.18.0 전 마지막 정리. 사용자 요청: "전체 코드베이스를 깔끔하고 알아보기 쉽게".

## Workspace lints

- `Cargo.toml` 의 `[workspace.lints.clippy]` 에 `pedantic = "warn"` (priority -1) + 의도적 allow-list 추가:
  - cast_possible_truncation / cast_possible_wrap / cast_sign_loss / cast_precision_loss — ONNX i64 / hash modular reduction 등 의도적 truncation.
  - doc_markdown / missing_errors_doc / missing_panics_doc — cosmetic doc style.
  - too_many_lines / module_name_repetitions / must_use_candidate / needless_pass_by_value / manual_let_else / items_after_statements / similar_names — informational only.
  - format_collect / match_wildcard_for_single_variants / trivially_copy_pass_by_ref / unnecessary_wraps — intentional patterns (exhaustive match, future Result variants 등).
  - default_trait_access — `Foo::default()` 가 idiomatic.
  - float_cmp — NLI / RRF score 의 explicit threshold 비교 의도.
  - struct_excessive_bools / case_sensitive_file_extension_comparisons / naive_bytecount / ignore_without_reason — domain-specific 의도.
  - format_push_string / return_self_not_must_use / match_same_arms — builder / wire-label / hot-path 패턴 보존.
  - needless_continue / used_underscore_binding / nonminimal_bool / unreadable_literal / many_single_char_names / doc_link_with_quotes / assigning_clones / collapsible_str_replace / trivial_regex / elidable_lifetime_names / range_plus_one / explicit_iter_loop / implicit_hasher / ref_option — remaining low-value style.
- 각 24 crate `Cargo.toml` 에 `[lints] workspace = true` 추가.

## Auto-fix

`cargo clippy --workspace --all-targets --fix` 적용 — 128 files changed, 552 insertions / 472 deletions. 주로:
- uninlined_format_args (~18): `format!("{}", x)` → `format!("{x}")`.
- redundant_closure_for_method_calls (~33): `.map(|x| x.foo())` → `.map(T::foo)`.
- 그 외 mechanical refactor.

## 검증

- `cargo clippy --workspace --all-targets -j 1 -- -D warnings` clean (pedantic + 모든 lint group).
- `cargo test --workspace --no-fail-fast -j 1` — **1293 tests pass + 1 pre-existing flaky fail** (`kebab-mcp::tools_call_ask_multi_hop::ask_tool_routes_multi_hop_true_to_decompose_first`, HOTFIX candidate, cleanup 무관). 회귀 0.

Wire 영향: 없음.
Behavior 영향: 없음 (mechanical refactor only).

3a57cab1eb fix(kebab-store-sqlite): purge stale assets row on workspace_path orphan + smoke
P7-3 통합 테스트가 노출한 storage 레이어 버그 fix.
`assets.workspace_path` 의 UNIQUE 제약과 `upsert_asset_row` 의
`ON CONFLICT(asset_id)` 만 처리하던 gap 사이 — byte 가 변경된 자산
re-ingest 시 새 asset_id 가 같은 workspace_path 에서 secondary UNIQUE
충돌. md / image / pdf 모두 영향.

Fix:
- 새 helper `purge_orphan_at_workspace_path` 가 같은 `workspace_path`
  의 *다른* `asset_id` 를 발견하면 documents → assets 순서로 sweep.
  documents 의 ON DELETE RESTRICT 회피 + CASCADE 로 blocks / chunks /
  embedding_records 정리. copied 모드면 storage_path 의 byte 파일도
  best-effort 삭제.
- `put_asset_with_bytes` 의 두 분기 (copy / reference) + `DocumentStore
  ::put_asset` 모두 호출.
- 회귀 테스트 `put_asset_with_bytes_sweeps_workspace_path_orphan` (이전
  의 "UPSERT 실패시 orphan 청소" 테스트가 더 이상 doable 하지 않으므로
  대체).
- `re_ingest_edited_pdf_produces_new_doc_id` integration `#[ignore]` 해제 →
  9 통합 테스트 모두 default 로 통과.

Vector store orphan 은 별도 P+ task — LanceDB 가 SQLite cascade 와 무관하게
운영되므로 stale chunk_id vector 가 디스크에 남음. 검색에는 영향 없음 (search 가
SQLite join 통해 surface).

Smoke 검증 (release binary, markdown 2 + image 1 + PDF 2):
- doctor pass
- 첫 ingest: 5 new
- list docs: 5 docs all media types
- search lexical "pdf-page-v1 chunker" → whitepaper.pdf hit
- search hybrid → cross-media 결과
- inspect doc PDF: parser_version=pdf-text-v1, blocks 가 SourceSpan::Page
- 동일 byte re-ingest: 5 updated, 0 errors (P1 idempotency)
- byte 수정 후 re-ingest: 1 new (해당 PDF) + 4 updated, 0 errors (storage fix)
- corrupt PDF 추가: errors+=1 + IngestItem.error 메시지 정확, 다른 자산 영향 0
- 정리 후 다시 ingest: errors=0
- RAG ask: PDF 인용 + `citations[].citation` 에 `kind: "page"` + `page: <N>` +
  `path: <pdf_path>` 정확히 노출

운영 fixture 보조:
- `crates/kebab-parse-pdf/examples/gen_smoke_pdf.rs` — `cargo run --release
  --example gen_smoke_pdf -p kebab-parse-pdf -- <out.pdf> <text-pages>` 로
  reportlab/qpdf 없이 in-tree PDF 생성.
- `crates/kebab-parse-image/examples/gen_smoke_png.rs` — 동일 방식의 PNG
  fixture 생성.
- SMOKE.md 가 두 example 사용법 + 갱신된 HOTFIXES 동작 (byte 수정 시
  errors+=1 → new+=1) 반영.

HOTFIXES `2026-05-02 P7-3` entry 가 \"deferred\" → \"fixed in same PR\" 로
업데이트, vector store orphan caveat 만 남음.

8de08cf38c review(p7-1): 회차 1 지적 반영
- Cargo.toml: 사용하지 않는 deps 제거 (`kebab-config`, `thiserror`,
  `pdf-extract`, dev `tempfile` / `serde_json` / `serde`). 특히
  `pdf-extract` 가 끌어오던 transitive ~150 crate (pom, postscript,
  type1-encoding-parser, adobe-cmap-parser, euclid, chrono, md5,
  linked-hash-map …) 가 모두 사라짐. lopdf 만 남음.
- info.rs: BOM 없는 PDFDocEncoded Title 디코드 버그 수정. `from_utf8_lossy`
  는 0x80–0xFF 를 U+FFFD 로 치환해 "Café" 같은 레거시 타이틀을 망가뜨림.
  byte → `char` 직접 캐스팅 (Latin-1 디코더) 로 교체. 회귀 테스트
  `info_dict_title_pdfdocencoding_latin1_high_bytes_decoded` 추가.
- info.rs: 모듈 doc 의 "Latin-1 superset" 부정확 표현 정정 — PDFDocEncoding
  은 0x18–0x1F / 0x80–0x9F 영역에서 Latin-1 과 다름.
- lib.rs: `saturating_sub(1)` 가 page=0 케이스를 silent 흡수하던 부분에
  `debug_assert!` 추가. release 는 saturating fallback 유지 (panic 보다
  garbled order 가 운영에 유리).
- tests: UTF-16 surrogate pair 커버리지 갭 보완 — 🥙 (U+1F959) 가 포함된
  타이틀로 `String::from_utf16_lossy` 의 페어-결합 경로 검증.

5a158d7343 feat(kebab-parse-pdf): P7-1 text PDF extractor — per-page CanonicalDocument
`PdfTextExtractor`(MediaType::Pdf) lopdf 기반 per-page 텍스트 추출.
페이지마다 `Block::Paragraph` + `SourceSpan::Page { page, char_start, char_end }`
emit. 본문이 비거나 추출 panic 인 페이지는 빈 paragraph + `Provenance::Warning`
("scanned candidate") 로 표시 — 이후 OCR fallback (별도 task) 의 입력.

핵심 동작:
- `lopdf::Document::load_mem` + `is_encrypted()` → 암호화 PDF 는 명시 에러
  (`qpdf --decrypt` 안내).
- 페이지 단위 `extract_text(&[page])` 를 `catch_unwind` 로 감싸 malformed
  page panic 을 recoverable warning 으로 변환.
- `/Info` dict 에서 Title/Producer/Creator best-effort 추출. UTF-16BE BOM
  prefixed 문자열도 디코드 (한국어 등 non-ASCII Title 정상 처리).
- 9개 통합 테스트: 3-page emit, scanned-mixed warning, encrypted refuse,
