- scan_department_mismatches: detect department/cost center drift
- scan_name_variance_mismatches: detect display name inconsistencies
- Add comprehensive integration test suite (tests/integration_test_audit_shard.py)
- Create demo client (test_client.py) and MCP protocol simulator (test_mcp_protocol.py)
- Add tool catalog generator (list_tools.py) for visibility across all 33 registered tools
- Fix Windows console encoding in src/main.py to support emoji in shard status output
- Add version management utility (scripts/bump_version.py) for release automation
- Update workday test imports to use new drift_detection module path
Completes session goal of establishing SOC 2-compliant cross-system drift detection
