## Strategic Decisions Summary

### 1. Core Value Proposition
**"Obsidian for Code Projects, Built for Claude"**

- Category: Project Memory System for AI Development
- Positioning: New category creation (not competing directly with existing tools)
- Target: Individual developers and small teams using Claude Code

### 2. Unified Memory Model (v0.15.0)

**Problem**: Too many APIs (KB, Tasks, Repository Map) → confusion
**Solution**: Single Memory Entry concept with types

```python
class MemoryEntry(BaseModel):
    id: str
    type: Literal["knowledge", "decision", "code", "task", "pattern"]
    title: str
    content: str
    category: str
    tags: List[str]
    related_to: List[str]  # Relationships
    source: str  # "manual", "git-commit", "code-analysis"
    confidence: float  # 0.0-1.0
```

**Benefits**:
- ✅ Single API to learn
- ✅ Automatic relationship detection
- ✅ Cross-domain search (KB + Tasks + Code)
- ✅ Intelligent suggestions

### 3. Staged Deletion Strategy

**Critical Principle**: "削減すること自体は問題無い。ただし、ロードマップと残す機能が整合性を持って動作する必要がある"

**v0.15.0** (2026-01-24): Deprecation only, **NO deletion**
- Backward compatibility layer implemented
- All features work (with warnings)
- Tests: 1,953 → 2,081 (+128 for compatibility)
- 2-month validation period

**v0.16.0** (2026-03-20): Actual deletion
- Deprecated features removed
- Memory System only
- Tests: 2,081 → 1,201 (-38% but >85% coverage maintained)
- Cleaner codebase

**Operational Guarantees**:
- ✅ All existing workflows work in v0.15.0
- ✅ Migration script provided
- ✅ Deprecation warnings guide users
- ✅ Documentation updated
- ✅ Tests maintain >85% coverage

### 4. Development Efficiency with SubAgents

**Original Plan**: 8 weeks sequential development
**Optimized Plan**: 40 days (6 weeks) with parallelization and QA

**Efficiency Gains**:
- 15 SubAgents across 4 phases
- Parallel execution where possible
- Time reduction: -29% (8 weeks → 6 weeks)
- Quality improvement: 85% → 95%+ coverage

**Quality Assurance Strategy** (3 layers):
1. **Layer 1** (Development-time): Each SubAgent has quality requirements
2. **Layer 2** (Phase-completion): Comprehensive review using improved prompts
3. **Layer 3** (Critical issues): Manual review by human

### 5. Market Positioning

**Market Sizing**:
- TAM: $43M (AI development tools market segment)
- SAM: $2.9M (Claude Code users with complex projects)
- SOM (5 years): $580K-840K ARR

**Conclusion**: Suitable for side project/OSS, potential for niche market leadership

**Risk Assessment**: ✅ LOW - Focus on core value, realistic scope

## Next Steps

### Immediate Actions (2025-11-27 - Week 1 Day 1)

1. **Read Implementation Plan**
   - `docs/v0.15.0_IMPLEMENTATION_PLAN.md` (90 min)
   - `docs/v0.15.0_SUBAGENT_PLAN.md` (75 min)

   - Verify test suite: `pytest --cov=clauxton`
   - Verify quality tools: `mypy clauxton && ruff check clauxton`

3. **Start Agent 1: Memory Core**
   - Create `clauxton/core/models.py` - Add MemoryEntry model
   - Create `clauxton/core/memory_store.py` - Memory storage
   - Create `clauxton/core/memory.py` - Memory operations
   - Write tests (TDD approach)
   - Target: Day 1-7 (1 week)

4. **Quality Requirements**

## Lessons Learned from Planning Phase

### What Went Well ✅
1. **User-Driven Refinement**: User's feedback about "本質に沿ってブラッシュアップ" led to better solution (Unified Memory Model) instead of simple deletion
2. **Operational Guarantee Focus**: User's concern about "削除しても正常に動作" forced us to design staged deletion with backward compatibility
3. **Quality Assurance Integration**: Proactive 3-layer QA strategy addresses quality concerns upfront
4. **Parallelization Strategy**: SubAgent plan reduces timeline by 29% while improving quality

### What Could Be Improved 🔄
1. **Earlier Validation Planning**: Should have considered operational guarantees from the start, not after initial deletion proposal
2. **Test Strategy Clarity**: Should have detailed test conversion strategy earlier
3. **Documentation Migration**: Could have been more explicit about which docs get deleted/replaced/updated

### Key Insights 💡
1. **"削減" ではなく "統合と深化"**: Reduction is not the goal; refining the essence is. This mindset shift led to Unified Memory Model.
2. **Backward Compatibility is Critical**: v0.15.0 with NO deletion (only deprecation) ensures users have time to migrate safely.
3. **Quality Can't Be Bolted On**: 3-layer QA approach integrated into development process, not after.
4. **Market Realism**: Honest assessment ($580K-840K ARR) helps set realistic expectations for side project/OSS.

## Risks and Mitigations

### Risk 1: Migration Complexity ⚠️
**Risk**: Users find migration from KB/Task to Memory too complex
**Mitigation**:
- Automatic migration script provided
- Backward compatibility layer (v0.15.0)
- 2-month grace period before deletion
- Comprehensive migration guide

### Risk 2: Performance Regression ⚠️
**Risk**: Unified Memory Model slower than specialized APIs
**Mitigation**:
- Performance benchmarks in Phase 2 (Day 12)
- Targets: Memory.search() <100ms for 10K entries
- Optimization focus in Week 3-4 (Smart Memory)
- Performance tests required

### Risk 3: Scope Creep ⚠️
**Risk**: Adding features beyond Unified Memory Model
**Mitigation**:
- Clear scope defined in v0.15.0_IMPLEMENTATION_PLAN.md
- "本質に沿ってブラッシュアップ" principle guides decisions
- Phase-by-phase validation prevents drift

### Risk 4: Quality Shortcuts ⚠️
**Risk**: Time pressure leads to skipping tests or quality checks
**Mitigation**:
- 3-layer QA approach enforced
- TDD approach required
- Phase-completion reviews mandatory
- Rollback procedures defined
