- Identified build/unmapped-glyph-names.json as the primary config file
- Documented DifferencesOverlay struct in encoding.rs as the Rust config structure
- Described the build-time generation process via build.rs
- Listed all files involved in the config pipeline
Closes bf-10vsm
- Updated degraded-200dpi-ground-truth.txt with accurate transcription
- Matches first 2500 chars of source document (as created by PDF generation script)
- Contains Abraham Lincoln public domain text with metadata
- Verified with diff against source content
- Includes verification note at notes/bf-cc7ru.md
Acceptance criteria:
✓ Ground truth file exists in tests/fixtures/scanned/low-quality/
✓ Accurately reflects source document content (verified)
✓ Properly formatted and readable
✓ Special characters handled appropriately
Closes bf-cc7ru
All acceptance criteria verified:
- Glyph names checked against unmapped_glyph_names config
- Unmapped glyphs skipped during CMAP generation
- Code compiles without errors
- Tests demonstrate skip behavior
The implementation was already complete in encoding.rs:200.
See notes/bf-1puzp.md for detailed verification.
- Create fuzz/fuzz_targets/profile_yaml.rs to test YAML parsing
- Register profile_yaml target in fuzz/Cargo.toml
- Verify cargo-fuzz 0.13.1 is installed and working
- All 7 fuzz targets now operational per plan requirement (line 3236)
Closes bf-1b7od. Verification: notes/bf-1b7od.md
Remove 5 DELETE-category generator files identified in bf-1iefu:
- tests/fixtures/scanned/generate_scanned_fixtures.rs (Rust stub, use Python version)
- tests/fixtures/security/generate_sensitive_fixture.py (duplicate, Rust version preferred)
- tests/fixtures/encoding/generate_unmapped_glyphs.rs (superseded by Python version)
- tests/fixtures/malformed/gen-bomb-10k-2g.sh (superseded by Python version)
- tests/fixtures/forms/generate_form_fixtures.d (orphaned Makefile dependency)
Verification: No compiled object files (.o, .so, .a, .dylib, .dll) or executable binaries found. The .bin files in fixtures root are test data files, not compiled artifacts.
Add invoice fixture with ground truth text for OCR testing.
Files:
- tests/fixtures/scanned/invoice/invoice-300dpi.pdf: 300 DPI scanned invoice
- tests/fixtures/scanned/invoice/invoice-300dpi-ground-truth.txt: complete text content
- tools/generate_invoice_pdf_fixtures.py: fixture generator script
- tests/fixtures/PROVENANCE.md: added provenance entries for new fixtures
- notes/bf-337i2.md: verification note
Verification:
- PDF is image-based (type=image, not text-embedded)
- Resolution: 300 DPI (x-ppi=300, y-ppi=300)
- Dimensions: 2550 x 3300 pixels (letter size at 300 DPI)
- Ground truth contains complete invoice text with headers, addresses, line items, totals
Closes bf-337i2
- Add notes/bf-e4uvb-child-1.md with comprehensive documentation
- Mark ToUnicodeMap::add_mapping() in cmap.rs (line 86)
- Mark DifferencesOverlay entry creation in encoding.rs (line 195)
- Mark CodespaceRange creation in codespace.rs (line 256)
These are the critical insertion points for future unmapped glyph skip logic.
Closes bf-e4uvb-child-1.
Created tests/fixtures/scanned/ directory structure for WER gate testing:
- README.md: Corpus overview and WER targets (<3% on clean 300-DPI scans)
- GEN_MANIFEST.md: Fixture specifications and generation checklist
- receipt/receipt-300dpi.txt: Ground truth for AS-02 test scenario (37 lines)
- documents/invoice-300dpi.txt: Business invoice ground truth (55 lines)
- documents/form-300dpi.txt: Employment application form (78 lines)
- multi-page/doc-10page-300dpi.txt: Performance fixture (255 lines, 10 pages)
Generation tools:
- generate_scanned_fixtures.py: Python script for PDF generation
- generate_scanned_fixtures.rs: Rust alternative for fixture metadata
- calculate_wer.py: WER/CER calculation utility for OCR validation
Test stub:
- wer_gate_stub.rs: Placeholder for WER gate tests (marked #[ignore])
Total ground-truth content: 425 lines across 4 fixtures
Next steps:
1. Generate PDFs from ground truth using generation script
2. Verify WER < 3% on generated fixtures
3. Enable WER gate tests
