# Verification: resolver.rs Uses New Diagnostic Format

**Bead ID:** bf-6066g
**Date:** 2026-07-06
**Task:** Verify resolver.rs uses new diagnostic message format

## Summary

✅ **PASS** - All unmapped glyph assertions in `resolver.rs` use the new diagnostic format.

## Findings

### Unmapped Glyph Assertions: 1 found

**Test:** `test_resolve_level2_unmapped_code` (lines 868-880)

```rust
assert!(
    result.is_failure(),
    "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."
);
```

### Format Verification

The assertion correctly uses the new diagnostic message template:
- ✅ **Description:** "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..."

### Count Verification

- **Catalog (bf-1azpa):** 1 unmapped glyph assertion expected
- **Actual:** 1 unmapped glyph assertion found
- **Match:** ✅ Exact

### Generic "assertion failed" Messages

- ✅ **None found** - All unmapped glyph assertions use custom messages

## Comparison with Catalog

From `notes/bf-1azpa-catalog.md`:
- resolver.rs expected: 1 unmapped glyph assertion
- resolver.rs actual: 1 unmapped glyph assertion
- Status: ✅ MATCH

## Total Assertions in resolver.rs

The file contains 61 total assertions (including non-unmapped tests), but only 1 is specifically for unmapped glyph testing:
- **Unmapped glyph assertions:** 1 (updated with new format)
- **Other assertions:** 60 (out of scope for this verification)

## Acceptance Criteria

- ✅ All unmapped glyph assertions in resolver.rs use new message format
- ✅ No generic 'assertion failed' messages remain in unmapped tests
- ✅ Count matches expected from inventory (bf-1azpa catalog)

## Conclusion

**Status:** PASS ✅

All unmapped glyph assertions in `crates/pdftract-core/src/font/resolver.rs` have been successfully updated to use the new diagnostic message format. No generic assertion messages remain.
