- zod: 3.25.76 → 4.3.5
- @types/node: 20.19.27 → 25.0.6

**Recommendation**:
- Test major version upgrades in development branch
- Evaluate breaking changes before upgrading
- Consider dependency update schedule

## Detailed Analysis

### Code Metrics

| Metric | Value |
|--------|-------|
| Source code | 2779 lines (22 files) |
| Test code | 2340 lines (13 files) |
| Test/Code ratio | 0.84:1 |
| Modules | 11 |
| Dependencies (prod) | 4 |
| Total dependencies | 345 |
| Security vulnerabilities | 0 |

### Test Suite Analysis

**Structure**: Well-organized
- Unit tests: formatting, HTTP, URI, URL generation, search
- Integration tests: package, organization, datastore, group, resources, status
- Fixture-based mocking with realistic CKAN responses

**Quality**: Good test design
- Clear test descriptions
- Proper use of vitest and mocking
- Edge case coverage in tested modules

**Gap**: Main tools not tested
- package.ts: 712 lines, 12.5% coverage
- Most business logic not executed by tests
- Risk of regressions during refactoring

### Architecture Assessment

**Separation of Concerns**: Excellent
