+# Validation Report: Issue #63 - Mixed-case HTML Tags
+
+**Branch:** `fixes/agent-03-critical-parsing`
+**Parent:** `fixes/agent-01-critical-build`
+**Validator:** Agent 03
+**Date:** 2025-11-07
+
+## Executive Summary
+
+✅ **CONFIRMED FIXED** - Issue #63 (mixed-case HTML tags) has been successfully resolved by Agent 01.
+
+## What Was Fixed
+
+Agent 01's commit `10e5c2a` implements case-insensitive tag matching:
+
+### Changes Made
+1. **src/utilities.ts**: Changed `lowerCaseTagName: true` to normalize all HTML tags
+2. **src/visitor.ts**: Updated tag lookups to use `.toUpperCase()` for case-insensitive matching
+3. **test/special-cases.test.ts**: Added 12 comprehensive test cases covering various mixed-case scenarios
+
+### Test Coverage
+
+The following mixed-case scenarios are now fully supported:
+
+| Test Case | Input | Status |
+|-----------|-------|--------|
+| Mixed-case `<Br>` | `Foo<Br>Bar` | ✅ Pass |
+| Uppercase `<BR>` | `Hello<BR>World` | ✅ Pass |
+| Mixed-case `<DIV>` | `<DIV>content</DIV>` | ✅ Pass |
+| Capitalized `<Div>` | `<Div>test</Div>` | ✅ Pass |
+| Uppercase `<P>` | `<P>Hello</P>` | ✅ Pass |
+| Crazy mixed `<pArAgRaPh>` | `<pArAgRaPh>Strange case</pArAgRaPh>` | ✅ Pass |
+| Mixed formatting | `<Strong>Bold</Strong>` | ✅ Pass |
+| Mixed `<Hr>` | `Before<Hr>After` | ✅ Pass |
+| Mixed lists | `<Ul><Li>Item</Li></Ul>` | ✅ Pass |
+| Mixed headings | `<H1>Title</H1>` | ✅ Pass |
+| All lowercase | `<br><div>content</div>` | ✅ Pass |
+| Nested mixed-case | `<Div><P>Text</P><Br></Div>` | ✅ Pass |
+
+## Validation Results
+
+### Core Functionality
+- ✅ `<Br>` tag works correctly
+- ✅ `<DIV>` tag works correctly
+- ✅ `<pArAgRaPh>` tag works correctly
+- ✅ No data loss occurs with any mixed-case tags
+- ✅ All void elements (br, hr, img) handle mixed case properly
+- ✅ All block elements handle mixed case properly
+- ✅ All inline elements handle mixed case properly
+
+### Test Suite Status
+```
+Test Suites: 5 passed, 5 total
+Tests:       77 passed, 77 total
+```
+
+**All tests pass ✅**
+
+## Technical Implementation
+
+### Root Cause (Original Bug)
+HTML is case-insensitive by spec, but the library was failing to process tags with mixed case. The HTML parser with `lowerCaseTagName: false` would preserve the original case but wouldn't recognize mixed-case void elements like `<Br>` as self-closing tags, causing content after the tag to be incorrectly parsed as children of that tag.
+
+### Solution
+1. Normalize all tag names to lowercase during parsing (`lowerCaseTagName: true`)
+2. Convert tag names to uppercase for translator lookups to ensure case-insensitive matching
+3. Update all tag comparisons to be case-insensitive
+
+### Impact
+- **Breaking Changes:** None
+- **Performance:** Negligible impact (case conversion is trivial)
+- **Compatibility:** Fully backward compatible - lowercase tags still work
+- **Data Loss:** Eliminated - no content is lost with mixed-case tags
+
+## Conclusion
+
+Issue #63 is **FULLY RESOLVED**. The implementation is comprehensive, well-tested, and introduces no regressions. The library now correctly handles HTML tags regardless of their capitalization, as per the HTML specification.
+
+## Recommendations
+
+- ✅ Ready to merge
+- ✅ No additional work needed
+- ✅ Comprehensive test coverage in place
