# Verification Note: bf-6bsry - Select and verify test fixture

## Task
Choose a small, fast PDF fixture from tests/fixtures/encoding/ and verify it exists and is readable.

## Acceptance Criteria - ALL PASS

### ✅ PASS: Verify tests/fixtures/encoding/ directory exists
- Directory exists at `/home/coding/pdftract/tests/fixtures/encoding/`
- Contains 14 files (7 PDF files, 7 supporting files)

### ✅ PASS: List available PDF files in the directory
Available PDF fixtures (all < 50KB):
1. `agl-only.pdf` - 597 bytes
2. `fingerprint-match.pdf` - 1,059 bytes (SELECTED)
3. `no-mapping.pdf` - 660 bytes
4. `shape-match.pdf` - 926 bytes
5. `test_working_copy.pdf` - 374 bytes
6. `unmapped-glyphs.pdf` - 723 bytes

### ✅ PASS: Select fingerprint-match.pdf (recommended)
- **Selected fixture**: `tests/fixtures/encoding/fingerprint-match.pdf`
- **Size**: 1,059 bytes (~1KB) - well under 50KB threshold
- **Expected content**: Single word "Test" (from `fingerprint-match.txt`)

### ✅ PASS: Confirm the selected file exists and is readable
- File exists: ✓
- Readable permissions: ✓ (`-rw-r--r--`)
- Valid PDF header: ✓ (starts with `%PDF`)
- Exact size: 1,059 bytes

## Documentation for Subsequent Beads

**Chosen fixture path**: `tests/fixtures/encoding/fingerprint-match.pdf`

This fixture will be used for all subsequent child beads requiring a small, fast encoding test fixture.

## Rationale for Selection

- **Size**: 1KB - minimal overhead for fast test execution
- **Simplicity**: Extracts to single word "Test" - easy to verify correctness
- **Purpose**: Designed for font fingerprint matching tests (Phase 2.2 Level 3)
- **Consistency**: Recommended by task description

## Test Environment

- Working directory: `/home/coding/pdftract`
- Fixture path: `tests/fixtures/encoding/fingerprint-match.pdf`
- Fixture absolute path: `/home/coding/pdftract/tests/fixtures/encoding/fingerprint-match.pdf`

## Verification Commands Executed

```bash
# List directory
ls -lh tests/fixtures/encoding/

# Verify file size and permissions
ls -lh tests/fixtures/encoding/fingerprint-match.pdf

# Verify PDF magic bytes
head -c 4 tests/fixtures/encoding/fingerprint-match.pdf

# Get exact size
stat -c %s tests/fixtures/encoding/fingerprint-match.pdf

# View expected content
cat tests/fixtures/encoding/fingerprint-match.txt
```

## Conclusion

All acceptance criteria PASS. The fixture `tests/fixtures/encoding/fingerprint-match.pdf` is confirmed to exist, be readable, be a valid PDF, and meet the size requirements for fast execution.
