### 3. ⚠️ Compilation Validation (cargo check --all-features)
- **Status**: Failed (expected for incomplete implementation)
- **Errors**: 8 compilation errors
- **Warnings**: 23 warnings

#### Critical Errors Identified

##### 1. Lifetime Issues in `src/math/asciimath.rs`
**Error Type**: Lifetime may not live long enough
**Locations**:
- Line 194: `binary_op_to_asciimath` method
- Line 240: `unary_op_to_asciimath` method

**Issue**: Methods need explicit lifetime annotations for borrowed data.

**Fix Required**:
```rust
// Current (incorrect):
fn binary_op_to_asciimath(&self, op: &BinaryOp) -> &str

// Should be:
fn binary_op_to_asciimath<'a>(&self, op: &'a BinaryOp) -> &'a str
```

##### 2. Missing Type Imports
**Locations**: Multiple modules
**Issue**: Types used but not imported into scope

##### 3. Type Mismatches
**Error Type**: E0308 (mismatched types)
**Issue**: Type inference or explicit type declarations needed

##### 4. Method Resolution Failures
**Error Type**: E0599 (method not found)
**Issue**: Trait implementations or method signatures incorrect

##### 5. Missing Module Exports
**Error Type**: E0432 (unresolved import)
**Issue**: Public exports not properly declared

#### Warnings Identified

**Categories**:
- Unused variables (3 warnings)
- Unused mut declarations (1 warning)
- Other code quality issues (19 warnings)

**Note**: Most warnings are non-critical and can be addressed during code cleanup.
