## 🚨 Critical Missing Documentation

### 1. Tracking Module (`tracking/`)
**Status**: Completely undocumented

**Files**:
- `tracking/mod.rs` - Module interface
- `tracking/stats.rs` - Tracking statistics

**Impact**: High - Core functionality

### 2. Analysis Submodules
**Status**: All submodules undocumented

**Critical Submodules**:
- `detectors/` - Memory issue detectors (leak, UAF, overflow)
- `safety/` - Safety analysis
- `lifecycle/` - Lifecycle tracking
- `metrics/` - Metrics collection
- `quality/` - Quality analysis

**Impact**: High - Core analysis features

### 3. Capture Submodules
**Status**: Backend details not documented

**Critical Components**:
- `backends/` - 4 different backend implementations
- `platform/` - Platform-specific code
- `types/` - Capture data types

**Impact**: Medium - Implementation details
