## WebAssembly Analysis
### Bytecode Parsing
Static analysis of WASM binaries:
- Section parsing (type, function, memory, export)
- Instruction counting and categorization
- Memory usage estimation
### Resource Metrics
| Function count | Total WASM functions |
| Memory pages | Initial/max memory allocation |
| Import count | External dependencies |
| Export count | Public API surface |
| Instruction count | Total opcodes |
## Deep WASM Inspection
### Control Flow Analysis
- Basic block identification
- Loop detection and nesting depth
- Branch complexity measurement
- Unreachable code detection
### Phase 2 Plan
- Call graph construction across WASM modules
- Type-level analysis for interface validation
- Performance profiling instrumentation
## Quality Assurance
### WASM Integration Tests
```bash
cargo test --features wasm -- wasm_
```
- Validates bytecode parsing correctness
- Tests resource metric accuracy
- Verifies export/import resolution
## Presentar Pure-WASM Conversion
Convert demo visualizations from JavaScript to pure WASM:
- Presentar-core TUI framework
- No JavaScript dependencies
- Smaller bundle size
