### 3. Failed Subtask 3 (Gap Identified)

**Source File:** *Not found in workspace*

**Status:** ❌ **MISSING/FAILED** - Content gap

**Expected Content (based on task description pattern):**
- Likely contained: UI/UX design patterns or user interaction research
- May have included: User workflow analysis, persona definitions, or interaction design guidelines

**Gap Impact:**
- Missing user-centered design perspective
- No explicit user workflow documentation
- Interaction patterns not formally defined

**Synthesis Mitigation Strategy:**
- Infer user needs from Subtask 5 (interactive editing research)
- Derive UX patterns from Claude Code, Aider, and Cursor analysis
- Use PRD goals as proxy for user requirements

---

### 4. Failed Subtask 4 (Gap Identified)

**Source File:** *Not found in workspace*

**Status:** ❌ **MISSING/FAILED** - Content gap

**Expected Content (based on task description pattern):**
- Likely contained: Architecture or integration specifications
- May have included: System design, component interactions, or API definitions

**Gap Impact:**
- No formal architecture documentation beyond TUI specs
- Integration patterns between components not explicitly defined
- System boundaries unclear

**Synthesis Mitigation Strategy:**
- Infer architecture from existing source code in `src/` directory
- Use TUI technical specs as architectural baseline
- Derive integration patterns from PRD feature descriptions

### 5. Interactive File Editing CLI Tools Research (Subtask 5)

**Source Files:**
- `research_interactive_file_editing_cli_tools.md`
- `subtask5_interactive_file_editing_research_extracted.md`

**Status:** ✅ **COMPLETE** - Comprehensive research analysis

**Content Sections:**

#### 5.1 Tools Analyzed
1. **Claude Code**
   - Architecture: Agent SDK, Linux VM sandbox
   - Editing model: Tool-based with explicit file operations
   - Key characteristics: Explicit file addition, line-number/search-replace edits, confirmation required

2. **Aider**
   - Architecture: Python-based, git-integrated
   - Editing model: Multiple edit formats (whole, diff, diff-fenced, udiff, editor-diff/whole)
   - Smart matching: Perfect, whitespace-flexible, fuzzy (0.8 threshold), "Did you mean?" suggestions

3. **Cursor**
   - Architecture: VS Code-based IDE
   - Editing model: Inline generation, side-by-side diff, tab autocomplete, Composer for multi-file

#### 5.2 Diff Display Formats
- Terminal-based (Aider): Color coding (red/green), line numbers
- Side-by-side (Cursor): Split-pane, syntax highlighting, click-to-accept
- Unified diff: Standard format, Aider's udiff for LLM consumption

#### 5.3 Edit Confirmation Flows
- **Explicit confirmation** (Claude Code): Per-edit approval, preview, Yes/No/Edit prompts
- **Auto-commit** (Aider): Configurable, shows diff before commit, `/undo` command
- **Implicit/Automatic** (Cursor): Real-time edits, UI buttons, standard undo (Ctrl+Z)

#### 5.4 Undo/Redo Capabilities
- Git-based undo (Aider): Automatic commits, Conventional Commits format, `(aider)` attribution
- Editor undo (Cursor): Standard undo stack, persistent across sessions
- Hybrid approaches: Checkpoint system, session-based snapshots

#### 5.5 Best Practices Summary
- Edit format recommendations by use case
- Diff display best practices
- Confirmation flow patterns
- Undo strategy recommendations

#### 5.6 Synthesis Requirements
- **What exists:** Comprehensive analysis of 3 major tools with detailed patterns
- **What needs synthesis:** Selection of patterns for CodeTether TUI, adaptation to Ratatui constraints
- **Key insights for synthesis:**
  - Aider's diff format is most efficient for LLM communication
  - Explicit confirmation aligns with quality goals in PRD
  - Git-based undo provides audit trail (matches PRD's git history memory)
  - Color coding (red/green) is standard expectation

## Content Synthesis Matrix

| Source | Completeness | Synthesis Priority | Dependencies |
|--------|--------------|-------------------|--------------|
| Subtask 1 (PRD Summary) | 100% | High | None |
| Subtask 2 (TUI Framework) | 100% | High | None |
| Subtask 3 (Missing) | 0% | N/A | Must infer from Subtask 5 |
| Subtask 4 (Missing) | 0% | N/A | Must infer from code/src |
| Subtask 5 (CLI Research) | 100% | High | None |

## Synthesis Recommendations

### Immediate Synthesis Opportunities
1. **TUI Component Selection:** Map PRD goals (Subtask 1) to TUI widgets (Subtask 2)
2. **Edit Interaction Design:** Adapt CLI patterns (Subtask 5) to Ratatui implementation (Subtask 2)
3. **Confirmation Flow Design:** Combine Aider's diff format with PRD quality requirements

### Gap Mitigation Strategies
1. **For Subtask 3 (UX):** Use Subtask 5's tool analysis as proxy for user expectations
2. **For Subtask 4 (Architecture):** Reference `src/` directory and existing PRD implementations

### Critical Synthesis Questions
1. Which edit confirmation model best aligns with PRD's 100% quality check goal?
2. How can TUI widgets support the autonomous development workflow described in PRD?
3. What diff display format balances clarity with TUI performance constraints?

## Next Steps for Synthesis

1. **Cross-reference PRD goals with TUI capabilities** - Identify which widgets support which objectives
2. **Select edit interaction patterns** - Choose confirmation flows, diff formats, and undo strategies
3. **Define chat interface architecture** - Combine List/Paragraph/Scrollbar widgets for optimal UX
4. **Address gaps** - Document assumptions made for missing Subtasks 3 and 4
