6. ANALYSIS AND INSIGHTS
- All sensitive class, method, schema, region, and external service names have been replaced with generic placeholders (e.g., PaymentServiceImpl, RegionA, paymentPlatformService, SCHEMA_A, etc.)
- This document preserves the structure and logic of the original semantic trees for analysis, documentation, and testing purposes.
