c622e3a6b7 feat(bf-3gewx): create WER measurement script
Create scripts/measure-wer.sh that computes Word Error Rate between OCR output and ground truth text.

Features:
- Takes two arguments: <ocr_output_file> and <ground_truth_file>
- Computes WER using formula: (substitutions + insertions + deletions) / total_words
- Exit code 0 if WER ≤ 3%, otherwise exit code 1
- Includes --help for usage information
- Supports VERBOSE=1 for detailed output

Acceptance criteria verified:
- ✓ Script exists and is executable
- ✓ Identical inputs: WER = 0.00%, exit code 0
- ✓ 10% substitutions: WER = 11.11%, exit code 1
- ✓ --help shows usage

bf18b10091 chore(bf-a8031): remove tracked debug/scratch artifacts and compiled binaries
Remove 40+ tracked scratch artifacts violating the normative file layout:
- Debug scripts: debug_*.py, debug_*.rs
- Test scratch files: test_*.c, test_*.rs, test_*.py
- Compiled binaries: debug_parse_simple, test_empty, test_page_class, test_parse_simple, test_pdf, test_classifier_corpus, test_trailer_debug*, test_trailer_key*, test_trailer_parse*, libstdin.rlib
- Backup files: serve.rs.bak, v2.pdf.bak
- tests/fixtures/ compiled binaries and generator drafts: gen_fixtures, gen_ocr_fixtures, gen_suspects*, gen_unmapped_*, generate_suspects_fixture*, generate_suspects_fixtures.py
- Scratch project directories: gen_unmapped_bin/, gen_unmapped_configurable_bin/

Extend .gitignore to prevent future tracking:
- Compiled binaries in repo root and tests/fixtures/
- Debug/scratch files and backup files
- Output files (0, --1.ppm, mod, out.pdf, *.rlib)

Note: Some output files (0, --1.ppm, mod, out.pdf, memory-report.json) were not tracked and are now covered by .gitignore.
Useful generator scripts in tests/fixtures/ (generate_*.py, generate_*.rs) are preserved.

Verification: Repository structure now matches normative file layout from docs/plan/plan.md.

789db9d41c fix(bf-632yt): fix arithmetic operations causing premature script exit
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.

- 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)

- Selected 4 mapped AGL glyphs for comparison: /A, /B, /space, /uni0041
- Documented why each unmapped glyph fails all 4 mapping levels (ToUnicode,
  AGL lookup, font fingerprint, shape recognition)
- Provided recommended fixture structure with expected output
- Based on research from bf-1cvmt (notes/bf-1cvmt.md)

3ff4d1828f docs(bf-68f9i): document selected unmapped glyphs for test fixture
Created comprehensive glyph selection document for unmapped glyph test fixture.
Selected 4 unmapped glyph examples:
- PUA glyphs: /g001, /g002, /g003
- Custom encoding: /CustomA, /CustomB
- Orphaned codes: /NotAGlyph
- Non-AGL algorithmic: /glyph_0041

Selected 4 mapped AGL glyphs for comparison:
- /A, /B, /space (direct AGL entries)
- /uni0041 (algorithmic pattern)

Explained why each unmapped glyph fails all 4 mapping levels and provided
recommended fixture structure with expected output.

6c668c7e42 docs(bf-ttbb5): document no-mapping.pdf generation verification
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.

b175540d4b docs(bf-2g412): document technical approach for no-mapping.pdf fixture
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
