- corpus-licensing.md: OQ-01 resolution - all fixtures are synthetic with no external licensing
- font-fingerprinting.md: OQ-02 resolution - Level 3 fingerprint database methodology and curation pipeline
- ocr-accuracy.md: PB-3 fallback plan - Tesseract WER targets (3% primary, 5% fallback) with methodology
- pdf-2-coverage.md: PB-10/R10 analysis - PDF 2.0 feature compatibility matrix
All four files are required phase sign-off artifacts referenced in the plan.
Resolves OQ-01, OQ-02, PB-3, PB-10.
Fixed critical bug where validation script exited prematurely under
set -euo pipefail due to arithmetic operations returning non-zero exit
codes when evaluating to 0.
Changes:
- Replaced ((var++)) with var=$((var + 1))
- Replaced ((var += value)) with var=$((var + value))
- Restructured progress indicator to avoid modulo 0 result
Verification:
- Script now successfully validates all 1,260 corpus files
- Correctly reports 603 valid files with complete license info
- Detects 657 files with missing licenses (expected - PDFium test files)
- Exits with code 1 when validation fails (as designed)
Closes bf-632yt
Implement scripts/validate-corpus.sh to verify corpus integrity against
manifest.csv. Validates:

- License information presence
- Total counts (files, pages, size)
Exit 0 on success, non-zero on validation failure. Outputs summary with
total files, pages, size, and validation status.
Closes bf-632yt

Closes bf-3cwge
- Added PDF Structure section based on bf-4ozvw findings
- Updated SHA256 in profiles/PROVENANCE.md for encoding fixtures
- Section includes file characteristics, font analysis, and technical significance
Examine the no-mapping.pdf test fixture using PDF analysis tools:
- pdfinfo: extracted metadata (1 page, 660 bytes, PDF 1.4, letter)
- pdffonts: identified CustomNoMap Type 1 font with custom encoding
- Documented structural findings for later reference
Key finding: fixture uses custom encoding with no embedding, designed to
test pdftract's handling of glyphs without standard Unicode mappings.
Closes bf-4ozvw.
Verified that existing documentation at tests/fixtures/no-mapping.md
comprehensively catalogs the 3 unmapped glyphs (g001, g002, g003)
with CID numbers and explanations for why they're unmapped.
All acceptance criteria met - documentation already complete from
previous bead bf-68f9i.
Closes bf-644ci
Successfully executed generate_unicode_recovery_fixtures_bin to create
no-mapping.pdf fixture (650 bytes). Validated PDF structure includes
custom /CustomNoMap font with /Differences encoding, non-AGL glyph
names, and no ToUnicode entry. Ground truth contains U+FFFD × 3.
Closes bf-ttbb5.
Add comprehensive research documentation for creating a PDF fixture
that tests the ENCODING_NO_MAPPING failure mode.
Covers:
- PDF specification for fonts without ToUnicode CMap
- Custom encoding approach using /Differences array
- Tooling and library options (manual construction, ReportLab, lopdf)
- Test text content specification
- Fixture structure validation
- Recovery level exercise confirmation
- Complete implementation examples in Rust and validation script
References:
- PDF 1.7 Specification (ISO 32000-1:2008)
- Adobe Glyph List (AGL)
- Internal docs: pdf-fonts-and-encoding.md, cmap-format-and-cid-encoding.md
Acceptance criteria met:
- [x] Documented approach exists in notes/bf-f0xqd-research.md
- [x] Approach specifies how to create a font with no ToUnicode CMap
- [x] Approach includes tooling/library requirements
- [x] Approach specifies test text content for the fixture
Closes bf-2g412
The no-mapping.pdf fixture uses custom glyph names (/g001, /g002, /g003)
that are not in the Adobe Glyph List and cannot be recovered through any
Unicode recovery mechanism (no ToUnicode CMap, no standard encoding,
no AGL match).
The ground truth has been corrected from 'ABC' to three U+FFFD replacement
characters (���), which is the expected output when all encoding recovery
methods fail per the Failure Mode Taxonomy.
Also updated PROVENANCE.md with new SHA256 hashes for encoding fixtures
that were regenerated on 2026-07-02.
This fixture correctly exercises the ENCODING_NO_MAPPING failure mode as
specified in the plan (line 733).
Closes bf-f0xqd.
CJK fixtures and tests already exist from previous work:
- tests/fixtures/cjk/ contains all 4 required PDFs
- Ground truth files for each encoding (GB18030, Shift-JIS, EUC-KR, Big5)
- Tests in crates/pdftract-core/tests/cjk_encoding.rs and tests/test_encoding.rs
- Tests fail due to unimplemented CJK encoding (expected for Phase 2.3)
- Updated PROVENANCE.md with CJK fixture entries
Fixtures are ready for CJK encoding implementation.
Closes bf-3ourh

- fingerprint-match.pdf: PDF with embedded font for fingerprint matching
- shape-match.pdf: PDF with subset font for shape recognition
