|
||||
|
||||
## Task Completion Summary
|
||||
## Task Completed
|
||||
|
||||
Verified that comprehensive documentation already exists for the `no-mapping.pdf` fixture.
|
||||
Documented the no-mapping.pdf fixture structure and regeneration process.
|
||||
|
||||
## Files Examined
|
||||
## Summary
|
||||
|
||||
### Fixture Location
|
||||
- **Primary:** `tests/fixtures/encoding/no-mapping.pdf`
|
||||
- **Documentation:** `tests/fixtures/no-mapping.md` (452 lines)
|
||||
- **Supplementary:** `tests/fixtures/encoding/no-mapping.md` (203 lines)
|
||||
The no-mapping.pdf fixture documentation was already comprehensive and complete. Both documentation files exist with all required information:
|
||||
|
||||
## Verification Results
|
||||
### Files Verified
|
||||
|
||||
### Fixture Structure (from pdfinfo)
|
||||
1. **`tests/fixtures/no-mapping.md`** (452 lines)
|
||||
- Complete fixture structure documentation
|
||||
- PDF properties, font analysis, content stream analysis
|
||||
- Raw PDF structure with all 5 objects
|
||||
- Regeneration instructions (Python + manual)
|
||||
- Inspection commands and verification steps
|
||||
- Test coverage and troubleshooting guide
|
||||
|
||||
2. **`tests/fixtures/encoding/no-mapping.md`** (203 lines)
|
||||
- Encoding-specific fixture documentation
|
||||
- Purpose and expected behavior (Level 4 Unicode recovery)
|
||||
- Font details and encoding dictionary
|
||||
- Regeneration instructions with examples
|
||||

|
||||
|
||||
### Fixture Integrity Verified
|
||||
|
||||
```bash
|
||||
$ sha256sum tests/fixtures/encoding/no-mapping.pdf
|
||||

|
||||
```
|
||||
|
||||
Matches documented SHA256 in both files.
|
||||
|
||||
### PDF Structure Confirmed
