"""Integration test for 100% migration data preservation with reconciliation validation. Tests Quickstart Scenario 5: Legacy .project_status.md migration to PostgreSQL with comprehensive reconciliation checks ensuring zero data loss. Constitutional Compliance: - Principle V: Production Quality (100% data preservation, rollback on failure) - Principle VII: TDD (validates acceptance criteria) - Principle VIII: Type Safety (Pydantic validation throughout) Test Scenarios: 1. Complete migration with 5 reconciliation checks 2. Rollback on validation failure 3. Malformed YAML handling (skip with warning) 4. Vendor metadata completeness validation 5.
