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.
