kebab/crates/kebab-app/tests/ingest_pdf_ocr_smoke.rs

//! Integration smoke tests for the PDF OCR pipeline (§ Acceptance §9 #1 + #2).
//!
//! Tests 1 and 2 require a live Ollama endpoint — `#[ignore]` by default.
//! Manual invoke:
//!   KEBAB_PDF_OCR_ENDPOINT=http://192.168.0.47:11434 \
//!     cargo test -p kebab-app --test ingest_pdf_ocr_smoke --ignored -j 4
//!
//! Test 3 (cancel) uses a dummy endpoint + pre-set cancel — runs by default
//! to verify the cancel wiring doesn't panic/deadlock.
