 ## Approach
 
-### Phase 1: Analysis
+### Phase 1: Analysis ✅ COMPLETED
 - Compare current code with previous working version
 - Identify specific changes that caused the regressions
 - Document root causes
 
-### Phase 2: Fixes
+### Phase 2: Fixes ✅ COMPLETED
 - Fix JSON display mode rendering
 - Fix tabs UI alignment to left-align
 
-### Phase 3: Remaining Items
-- Implement any remaining items from TASKS.md that are not yet complete
-
-### Phase 4: Quality Assurance
-- Grade the final code using 0.00-100.00 scoring system
-- Categories with weights:
-  - Task completeness / alignment (25%)
-  - Correctness and bug risk (30%)
-  - Maintainability and clarity (20%)
-  - Documentation and comments (15%)
-  - Redundancy and complexity control (10%)
-
-### Phase 5: Delivery
-- Commit all changes
-- Create detailed PR with summary
+### Phase 3: Remaining Items ✅ COMPLETED

+
+### Per-File Grades
+
+#### 1. macros.html (Templates)
+| Category | Score | Justification |
+|----------|-------|---------------|
+| Task Completeness | 88 | Comprehensive macros for all rendering needs |
+| Correctness | 82 | Minor logic bug in index_pagination, missing alt attr on images |
+| Maintainability | 85 | Good structure, some long lines, view-toggle duplication |
+| Documentation | 92 | Excellent inline comments, clear parameter docs |
+| Redundancy | 78 | View-toggle pattern duplicated 8 times |
+| **Weighted Score** | **85.20** | |
+

+| Category | Score | Justification |
+|----------|-------|---------------|
+| Task Completeness | 85 | Comprehensive CLI and rendering implementation |
+| Correctness | 78 | Global variable risk, ANSI pattern incomplete |
+| Maintainability | 72 | 3000-line monolith, CSS/JS as strings |

+| Redundancy | 65 | ~200 lines duplicated between functions |
+| **Weighted Score** | **77.70** | |
+
+#### 3. Test Files
+| Category | Score | Justification |
+|----------|-------|---------------|
+| Task Completeness | 88 | 31 test classes, 140 tests pass |
+| Correctness | 82 | Duplicate test method found, time-dependent test |
+| Maintainability | 90 | Well-organized, good fixtures |
+| Documentation | 85 | Good docstrings, some gaps |
+| Redundancy | 70 | Some repetitive test patterns |
+| **Weighted Score** | **84.35** | |
+
+### Overall Project Score
+
+| Component | Weight | Score | Contribution |
+|-----------|--------|-------|--------------|
+| Templates (macros.html) | 30% | 85.20 | 25.56 |
+| Core (__init__.py) | 50% | 77.70 | 38.85 |
+| Tests | 20% | 84.35 | 16.87 |
+| **OVERALL** | **100%** | **81.28** | |
+
+### Key Issues Identified
+1. **Critical**: Duplicate test method silently ignored
+2. **High**: Global `_github_repo` variable thread-safety risk
+3. **Medium**: CSS/JS embedded as strings limits maintainability
+4. **Medium**: View-toggle pattern duplicated 8x in templates
+
+### Positive Highlights
+1. All 140 tests pass
+2. Comprehensive feature set implementation
+3. Good documentation with clear parameter explanations
+4. Well-organized CSS variable system
+5. Accessible copy button implementation
+
+### Phase 5: Delivery ✅ COMPLETED
