## 🎯 Gap Analysis

### Critical Gaps (Must Address)

#### 1. MCP Server Tests (Priority: HIGH)
**Current**: 0% coverage (206 lines)
**Required**: 8-10 tests covering 20 MCP tools
**Estimated**: 1.5-2 hours
**Session**: 11

**Justification**: MCP is primary interface for production use. Critical for release.

---

### Important Gaps (Should Address)

#### 2. Performance Tests (Priority: MEDIUM)
**Current**: Basic observation only
**Required**: 5-7 tests (1000+ entries, memory profiling)
**Estimated**: 1-1.5 hours
**Session**: 11

**Justification**: Important for scalability claims. Not blocking release.

#### 3. Config Tests (Priority: MEDIUM)
**Current**: 40% coverage (cli/config.py)
**Required**: 2-3 tests (confirmation_mode, persistence)
**Estimated**: 30 minutes
**Session**: 11

**Justification**: New v0.10.0 feature. Should be tested.

---

### Minor Gaps (Nice to Have)

#### 4. Concurrency Tests (Priority: LOW)
**Current**: Basic test only
**Required**: 3-5 tests
**Estimated**: 1 hour
**Session**: Future

**Justification**: CLI tool, concurrent use rare. Low priority.

#### 5. Regression Tests (Priority: LOW)
**Current**: Implicit (existing tests)
**Required**: 2-3 explicit tests
**Estimated**: 30 minutes
**Session**: Future

**Justification**: Minor version, backward compatible. Low risk.
