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).

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.

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,
  corrupt header error, page_count 메타, UTF-16BE Title, filename
  fallback, determinism, snapshot.

`parser_version = "pdf-text-v1"`. Allowed deps: `lopdf 0.32` + `pdf-extract 0.7`
(원본 spec 그대로). 본문 다국어 OCR fallback 은 §9.2 후속 task (out of scope).
