# Verification Note: bf-1xtsk

**Task:** Update resolver.rs assertion with new message  
**Assertion:** 73 (test_resolve_level2_unmapped_code)  
**Status:** VERIFIED - Already Updated

## Verification Details

### File: crates/pdftract-core/src/font/resolver.rs

**Test:** `test_resolve_level2_unmapped_code` (lines 868-880)  
**Assertion:** Line 873-879

### Current Assertion Message (lines 875-878)

```rust
"Level 2 resolution should fail for unmapped character codes. \
 Expected: result.is_failure() == true. \
 Found: false. \
 Why this matters: Most codes in StandardEncoding above 0x7F are unmapped and should fail Level 2 (encoding + AGL) resolution per build/unmapped-glyph-names.json filtering."
```

### Designed Message (bf-4kbre-messages.md, assertion 73)

```
"Level 2 resolution should fail for unmapped character codes. \
 Expected: result.is_failure() == true. \
 Found: false. \
 Why this matters: Most codes in StandardEncoding above 0x7F are unmapped and should fail Level 2 (encoding + AGL) resolution per build/unmapped-glyph-names.json filtering."
```

## Acceptance Criteria Status

✅ **PASS:** Assertion 73 uses new message format  
✅ **PASS:** No generic 'assertion failed' messages remain  
✅ **PASS:** Assertion logic unchanged (still tests `result.is_failure()`)  
✅ **PASS:** Message references build/unmapped-glyph-names.json as source of truth  
✅ **PASS:** Message follows bf-300b5 template structure

## Conclusion

The assertion was already updated with the designed message from bf-4kbre-messages.md. No file changes were required. The bead bf-1xtsk is complete as the acceptance criteria are met.
