Verification Note for bf-1739m

Task

Create PdfExtractor instance in test setup for truncated-flate tests.

Implementation

Status: Already complete - no changes needed

The test file /home/coding/pdftract/crates/pdftract-core/tests/test_truncated_flate_recovery.rs already contains multiple tests that create PdfExtractor instances using the fixture_path() helper.

Existing Tests that Create PdfExtractor Instances

test_truncated_flate_extraction_result_structure (lines 119-177)
```
let extractor = PdfExtractor::open(&path)
    .expect("Should open truncated_mid_stream.pdf with PdfExtractor");
```
- Creates PdfExtractor instance using fixture_path() helper
- Tests extraction result structure
- Status: ✅ PASS
test_truncated_flate_opens_with_extractor (lines 186-202)
```
let extractor = PdfExtractor::open(&path)
    .expect("Should open truncated-flate.pdf with PdfExtractor");
```
- Creates PdfExtractor instance using fixture_path() helper
- Tests basic opening behavior
- Status: ✅ PASS

Verification

Compilation Test

cargo test --package pdftract-core --test test_truncated_flate_recovery

Result: ✅ Compilation successful

Exit code: Tests compiled and ran successfully
6 tests found and executed
4 tests passed, 2 tests failed (due to fixture content, not PdfExtractor instantiation)

Test Results Summary

Test	Status	Notes
`test_truncated_flate_extraction_result_structure`	✅ PASS	Creates PdfExtractor, calls materialize_pages() and extract_page(0)
`test_truncated_flate_opens_with_extractor`	✅ PASS	Creates PdfExtractor, verifies fingerprint and page_count
`test_truncated_flate_fixture_exists`	✅ PASS	Verifies fixture file exists
`test_truncated_flate_emits_diagnostics`	✅ PASS	Parses document successfully
`test_truncated_flate_parses_as_pdf`	❌ FAIL	Fixture has no pages (not related to PdfExtractor creation)
`test_truncated_flate_partial_content_accessible`	❌ FAIL	Fixture has no pages (not related to PdfExtractor creation)

No Panic During Instantiation

Both tests that create PdfExtractor instances (test_truncated_flate_extraction_result_structure and test_truncated_flate_opens_with_extractor) passed without any panic or crashes, confirming that PdfExtractor instantiation works correctly.

The two failed tests fail because the fixture file has no pages (empty page array), which causes assertions about page count to fail. This is a fixture content issue, not a PdfExtractor instantiation issue.

Acceptance Criteria Status

✅ A test creates a PdfExtractor instance - Multiple tests create instances (lines 125, 192)
✅ The extractor is created using the fixture_path() helper - Both tests use fixture_path() (lines 122, 189)
✅ Test compiles successfully - Verified with cargo test
✅ No panic during instantiation - Verified: PdfExtractor creation tests passed without panic

Conclusion

The bead requirements are already fully met. The test file already contains:

A fixture_path() helper function (lines 18-24)
Multiple tests that create PdfExtractor instances using PdfExtractor::open(&path)
Successful compilation and execution without panics

No additional changes are required for this bead.
