+
+**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.
