Overview

This document contains comprehensive Lossless Semantic Trees that capture the complete semantic structure, relationships, and behavior of the PaymentServiceImpl class. These trees provide multiple perspectives for code analysis, documentation, refactoring, and testing while maintaining semantic fidelity to the original implementation.

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.
