### Quality Gates

- ✅ All 12 tests must pass
- ✅ Zero test regressions
- ✅ EXTREME TDD methodology (RED → GREEN → REFACTOR)
- ✅ Each fix must have regression test

---

## Sprint 41b: Re-enable 34 Ignored Tests

**Goal**: Reduce ignored test count from 34 to <10
**Duration**: ~6-8 hours
**Priority**: MEDIUM

### Strategy: Triage → Fix → Re-enable

#### Phase 1: Triage (1 hour)

Categorize all 34 ignored tests:
- **Category A**: Quick fixes (<30 min each) → Fix immediately
- **Category B**: Medium complexity (1-2 hours) → Schedule for Sprint 41
- **Category C**: High complexity (>2 hours) → Document, keep ignored, plan for Sprint 42+

#### Phase 2: Quick Wins - Category A (2-3 hours)

**Target**: Fix 10-15 tests with simple issues

Examples:
- **Language-specific tests** (4 tests): Update test data, re-enable
- **CLI tests** (2 tests): Fix argument parsing edge cases
- **Integration tests** (1 test): Update for new API structure

#### Phase 3: Medium Complexity - Category B (3-4 hours)

**Target**: Fix 5-10 tests requiring moderate work

Examples:
- **End-to-end tests** (4 tests): Update for TypeScript/JSX changes
- **Binary integration tests** (1 test): Fix timeout issues
- **Enhanced naming tests** (6 tests): Complete implementation

#### Phase 4: Document Remaining - Category C

**Target**: Clearly document why tests remain ignored

Examples:
- **Unified quality framework** (14 tests): Property tests needing refactor
- **Ruchy parser tests** (10 tests): Future feature (RED tests)
- **Real-world tests** (5 tests): Environment-specific

### Quality Gates

- ✅ At least 15 tests re-enabled (target: 20+)
- ✅ All re-enabled tests must pass
- ✅ Remaining ignored tests documented with plan
- ✅ Update `CLAUDE.md` with new ignore count

---

## Sprint 41c: Clean Up Dead Code Warnings

**Goal**: Eliminate 5 dead code warnings
**Duration**: ~1 hour
**Priority**: LOW

### Warnings to Fix

1. **`semantic_search_tools.rs:154`** - `field 'engine' is never read`
   - **Fix**: Use field OR mark with `#[allow(dead_code)]` with explanation

2. **`semantic_search_tools.rs:225`** - `field 'engine' is never read`
   - **Fix**: Same as above

3. **`semantic_search_tools.rs:310`** - `field 'engine' is never read`
   - **Fix**: Same as above

4. **`hallucination_detector.rs:509`** - `field 'similarity' is never read`
   - **Fix**: Implement semantic similarity OR document for Phase 2

5. **`clustering.rs:12`** - `field 'vector_db' is never read`
   - **Fix**: Implement clustering OR mark as future feature

### Approach

**Option A**: Suppress warnings (quick, acceptable for v2.164.0)
```rust
#[allow(dead_code)]  // Used in future semantic search Phase 2
engine: Arc<HybridSearchEngine>,
```

**Option B**: Implement features (longer, better long-term)
- Complete semantic search integration
- Wire up clustering engine

**Recommended**: Option A for Sprint 41, Option B for Sprint 42+

### Quality Gates

- ✅ Zero dead code warnings in release build
- ✅ All suppressions documented with rationale
- ✅ Plan created for future implementation

---

## Sprint 41d: Fix Clippy Environment

**Goal**: Enable full clippy analysis with `--all-features`
**Duration**: ~30 min - 1 hour
**Priority**: LOW

### Issue

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

### Solutions

#### Option 1: Install libclang (Recommended)

```bash
# Ubuntu/Debian
sudo apt-get install libclang-dev

# Fedora
sudo dnf install clang-devel

# macOS
brew install llvm
export LIBCLANG_PATH=/usr/local/opt/llvm/lib
```

#### Option 2: Run clippy without problematic features

```bash
# Exclude features requiring libclang
cargo clippy --all-targets -- -D warnings
```

#### Option 3: Conditional compilation

Add to `Cargo.toml`:
```toml
[features]
default = []
full = ["deep-wasm", "semantic-search"]  # Requires libclang
```

### Quality Gates

- ✅ `cargo clippy --all-targets --all-features` runs successfully
- ✅ Zero clippy warnings (or all documented)
- ✅ CI/CD updated with clippy check
