+# Phase 2 UI Regression Fixes - Plan of Action
+
+## Branch: `fix/phase2-ui-regressions`
+
+## Issues Identified
+
+1. **JSON Display Mode Broken**: When selecting "JSON" tab, the raw JSON is not displaying correctly
+2. **Tabs UI Alignment**: The tabs are centered which doesn't match the expected left-aligned design
+
+## Approach
+
+### Phase 1: Analysis ✅ COMPLETED
+- Compare current code with previous working version
+- Identify specific changes that caused the regressions
+- Document root causes
+
+### Phase 2: Fixes ✅ COMPLETED
+- Fix JSON display mode rendering
+- Fix tabs UI alignment to left-align
+
+### Phase 3: Remaining Items ✅ COMPLETED
+- A.2 Metadata Subsection - Implemented
+- B.3 Tool Call Headers with Type - Implemented
+
+### Phase 4: Quality Assurance ✅ COMPLETED
+
+## Final Code Grading Report
+
+### Grading Weights
+| Category | Weight |
+|----------|--------|
+| Task completeness / alignment | 25% |
+| Correctness and bug risk | 30% |
+| Maintainability and clarity | 20% |
+| Documentation and comments | 15% |
+| Redundancy and complexity control | 10% |
+
+### 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 |

+| Redundancy | 78 | View-toggle pattern duplicated 8 times |
+| **Weighted Score** | **85.20** | |
+
+#### 2. __init__.py (Core)
+| 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 |

+| **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
+- All commits made
+- PR created with detailed summary

+### A.3 Cell Subsections (Input/Output Split)
+
+**Status:** Completed (Score: 9.0/10)
 **Priority:** High
 **Dependencies:** None
 
-**Implementation Details:**
-- Add collapsible metadata section to each message
-- Use `<details>` tag with `.message-metadata` class
+**Implementation:**
+- `group_blocks_by_type()` function groups content blocks into thinking/text/tools
+- `render_assistant_message()` and `render_assistant_message_with_tool_pairs()` create cell structure
+- `cell` macro in macros.html creates collapsible `<details>` wrapper
+- CSS for `.cell`, `.thinking-cell`, `.response-cell`, `.tools-cell`
+- Per-cell copy buttons with keyboard accessibility and ARIA labels
+
+**Features:**
+- Thinking cell: closed by default
+- Response cell: open by default
+- Tools cell: closed by default, shows count
+- Expand/collapse indicator (▶ rotates on open)
+- Copy button per cell with "Copied!" feedback
+
+**Test Coverage:**
+- `test_group_blocks_by_type`: Verifies block grouping
+- `test_cell_structure_in_assistant_message`: Verifies cell HTML structure
+- `test_thinking_cell_closed_by_default`: Verifies default state
+- `test_response_cell_open_by_default`: Verifies default state
+- `test_tools_cell_shows_count`: Verifies tool count display
+- `test_cell_has_copy_button`: Verifies copy button presence
+- `test_cell_copy_button_aria_label`: Verifies accessibility
 
-**Data to Include:**
-- Timestamp (from message object)
-- Working directory (from session context)
-- Character count: `len(message_text)`
-- Token estimate: `len(message_text) // 4`
-- Tool call counts (use existing counting logic)
+---
 
-**Files to Modify:**
-- `src/claude_code_transcripts/__init__.py`: Add `render_metadata()` function
-- `src/claude_code_transcripts/templates/macros.html`: Add metadata macro
+### A.4 Per-Cell Copy Buttons
 
-**CSS Classes:**
-- `.message-metadata` - container
-- `.metadata-item` - row
-- `.metadata-label` - label
-- `.metadata-value` - value
+**Status:** Completed (Score: 7.5/10)
+**Priority:** High
+**Dependencies:** A.3
+
+**Implementation:**
+- Copy button added to each cell header in `cell` macro (macros.html)
+- CSS for `.cell-copy-btn` with hover, focus, and copied states
+- JavaScript handler using Clipboard API (`navigator.clipboard.writeText`)
+- Keyboard accessibility (Enter/Space key support)
+- ARIA labels for screen readers ("Copy Thinking", "Copy Response", "Copy Tool Calls")
+
+**Features:**
+- Visual feedback: button text changes to "Copied!" for 2 seconds
+- Color feedback: green background on success
+- Focus styling: outline for keyboard navigation
+- Contextual labels based on cell type
+
+**Known Limitations:**
+- No user-facing error notification (errors only logged to console)
+- No fallback for browsers without Clipboard API
+- Limited functional test coverage
+
+**Test Coverage:**
+- `test_cell_has_copy_button`: Verifies button HTML presence
+- `test_cell_copy_button_aria_label`: Verifies accessibility labels
+
+**What would improve the score:**
+- Add user-facing error notifications
+- Add fallback copy method for older browsers
+- Add functional tests for click/keyboard behavior
