## 🔴 Remaining Critical Issues

### Major System Components Still Needing Work
1. **BaseTable (41.2%)** - 🔶 IMPROVED BUT STILL NEEDS WORK
   - 57/97 methods failing (down from 73/97)
   - Fundamental table operations improving but not complete
   - **Builder pattern significantly better** (67.0% vs 41.2%)

2. **Table System (52-65%)** - GraphTable, NodesTable, EdgesTable
   - **Improved but needs more work**
   - File I/O operations still broken (`from_csv`, `to_parquet`)
   - Complex filtering operations need implementation

3. **Subgraph (50.0%)** - Graph collection operations
   - Algorithm implementations missing (`clustering_coefficient`, `transitivity`)
   - Complex graph operations need core development

## 🔍 Updated Root Cause Analysis

### 1. **SOLVED: Parameter Signature Mismatches**
**Status**: ✅ **FIXED**
```
✅ drop_columns: Now working with ['name', 'age'] parameter format
✅ group_by: Now working with column list parameters
✅ select: Now working with multiple column selection
```

### 2. **SOLVED: EdgesAccessor Introspection Failure**
**Status**: ✅ **FIXED**
```
✅ dir(g.edges): Now returns 44 methods (was 0)
✅ Python introspection: Works properly with __dict__ access
✅ Edge attribute access: g.edges.weight still works perfectly
```

### 3. **IMPROVED: Graph Parameter Generation**
**Status**: ✅ **SIGNIFICANTLY ENHANCED**
```
✅ Enhanced smart parameter generation for 15+ new parameter types
✅ Graph operations now handle complex method signatures properly
✅ Success rate doubled from 35.9% to 73.4%
```

### 4. **REMAINING: FFI Implementation Gaps**
**Pattern**: Advanced methods need core implementation
```
❌ transition_matrix: needs implementation in core first
❌ clustering_coefficient: not yet implemented in core
❌ Complex file I/O: missing FFI delegation patterns
```
