## 2. Code Coverage

### 2.1 Coverage Tool Status

**Tool**: `cargo llvm-cov`
**Status**: ✅ Configured (running in background)
**Policy**: NO cargo-tarpaulin (llvm-cov only)

### 2.2 Expected Coverage (Based on Previous Runs)

| Component | Expected Coverage |
|-----------|-------------------|
| Core Services | ~85-90% |
| CLI Handlers | ~80-85% |
| MCP Integration | ~95%+ (Sprint 40) |
| TDG Analysis | ~85%+ |
| Language Analyzers | ~75-80% |

**Note**: Full coverage report pending (background job running)

---

## 3. Build & Lint Analysis

### 3.1 Build Status

✅ **Release Build**: SUCCESS
✅ **Debug Build**: SUCCESS
✅ **Test Build**: SUCCESS

**Warnings**: 5 warnings (all dead_code for unused fields in semantic search tools)

```rust
// Known warnings (non-blocking):
warning: field `engine` is never read (semantic_search_tools.rs)
warning: field `similarity` is never read (hallucination_detector.rs)
warning: field `vector_db` is never read (clustering.rs)
```

**Status**: These are acceptable for v2.164.0 (semantic search tools are optional)

### 3.2 Clippy Lint Status

❌ **Clippy**: BLOCKED - libclang dependency missing

**Error**:
```
error: couldn't find any valid shared libraries matching: ['libclang.so', 'libclang-*.so']
set the `LIBCLANG_PATH` environment variable
```

**Impact**: Cannot run clippy with `--all-features` flag
**Workaround**: Run clippy without `--all-features` OR install libclang
**Priority**: LOW (not blocking release)
