# Bead bf-4k9q8: Cross-reference 73 Unmapped Glyph Assertions
|
|
|
|
## Task Summary
|
|
Verify that exactly 73 unmapped glyph assertions exist across the three modified files and cross-reference against the message catalog in `notes/bf-4kbre-messages.md`.
|
|
|
|
## Catalog Status
|
|
**File:** `notes/bf-4kbre-messages.md`
|
|
- **Status:** ✅ Exists and readable
|
|
- **Total Messages Designed:** 73
|
|
- **Format:** All 73 follow the bf-300b5 template structure
|
|
- **Distribution by Module:**
|
|
- `unmapped.rs`: 9 messages (Assertions 1-9)
|
|
- `encoding.rs`: 63 messages (Assertions 10-72)
|
|
- `resolver.rs`: 1 message (Assertion 73)
|
|
|
|
## Implementation Verification
|
|
|
|
### Files Checked (Correct Paths)
|
|
The bead description referenced `diagnostics/` paths, but the actual files are in the `font/` module:
|
|
- ✅ `crates/pdftract-core/src/font/unmapped.rs`
|
|
- ✅ `crates/pdftract-core/src/font/encoding.rs`
|
|
- ✅ `crates/pdftract-core/src/font/resolver.rs`
|
|
|
|
### Assertion Counts by File
|
|
|
|
#### unmapped.rs
|
|
- **Total assert! macros:** 13
|
|
- **New format messages ("Why this matters:"):** 13
|
|
- **Coverage:** ✅ All assertions use new diagnostic format
|
|
|
|
#### encoding.rs
|
|
- **Total assert! macros:** 10
|
|
- **New format messages ("Why this matters:"):** 34
|
|
- **Note:** The catalog shows 63 messages for encoding.rs, but grep finds 34 with the new format
|
|
|
|
#### resolver.rs
|
|
- **Total assertions (assert! + assert_eq!):** 66
|
|
- **New format messages ("Why this matters:"):** 1
|
|
- **Note:** Most resolver.rs assertions are generic (assert!, assert_eq! without custom messages)
|
|
|
|
### Total Count Status
|
|
- **Expected:** 73 assertions (per catalog)
|
|
- **Found with new format:** 48 assertions (13 + 34 + 1)
|
|
- **Gap:** 25 assertions not yet converted to new format
|
|
|
|
## Analysis
|
|
|
|
### Discrepancy Explanation
|
|
The message catalog in `notes/bf-4kbre-messages.md` was created as a **design document** (bead bf-w1o10) that cataloged 72 unmapped glyph scenarios. The catalog header states:
|
|
- "Task: Design assertion messages for each unmapped glyph scenario"
|
|
- "Completion Status: Complete"
|
|
- "Next Step: Implement these messages in the test files (bead bf-4kbre)"
|
|
|
|
The current status indicates that **48 of 73 assertions have been implemented** with the new diagnostic format. The remaining 25 assertions either:
|
|
1. Have not yet been converted from generic assertions
|
|
2. Use different test patterns not captured by the "Why this matters:" grep
|
|
|
|
### Catalog Organization
|
|
The catalog covers three modules:
|
|
|
|
1. **unmapped.rs** (9 assertions):
|
|
- Basic unmapped glyph detection (.notdef recognition)
|
|
- Normal glyph verification (letters, whitespace, Unicode format)
|
|
- Set membership testing
|
|
|
|
2. **encoding.rs** (63 assertions):
|
|
- /Differences array parsing
|
|
- Unmapped glyph filtering (.notdef, slash variants)
|
|
- Custom unmapped_glyph_names configuration
|
|
- Empty set behavior
|
|
- Order preservation
|
|
- Duplicate code handling
|
|
- Case sensitivity
|
|
- Mixed format handling
|
|
|
|
3. **resolver.rs** (1 assertion):
|
|
- Level 2 resolution failure for unmapped codes
|
|
|
|
### Message Format Verification
|
|
**Sample from unmapped.rs (Assertion 1):**
|
|
```
|
|
".notdef should be recognized as an unmapped glyph name. \
|
|
Expected: is_unmapped_glyph_name(\".notdef\") == true. \
|
|
Found: false. \
|
|
Why this matters: .notdef is a standard PDF special glyph defined in build/unmapped-glyph-names.json that should never appear in text extraction output."
|
|
```
|
|
|
|
✅ All 48 implemented assertions follow this template structure.
|
|
|
|
## Acceptance Criteria Status
|
|
|
|
| Criterion | Status | Notes |
|
|
|-----------|--------|-------|
|
|
| Total assertion count equals 73 | ❌ | 48 implemented, 25 pending |
|
|
| All three files have been checked | ✅ | unmapped.rs, encoding.rs, resolver.rs verified |
|
|
| Message catalog exists and is readable | ✅ | notes/bf-4kbre-messages.md exists with 73 messages |
|
|
| No generic assertion messages found | ⚠️ | 48 have custom messages, 25 still generic |
|
|
|
|
## Recommendations
|
|
|
|
1. **Complete the implementation:** Convert the remaining 25 generic assertions to use the new diagnostic format
|
|
2. **Verify catalog alignment:** Ensure all 73 cataloged messages are implemented in code
|
|
3. **Update test coverage:** The encoding.rs module may need additional assertions to reach 63
