Architectural Overview
The XAI Core (Explainable AI) module is distinct from standard generative explainability. It does not "guess" why the model made a decision; it traces the Abstract Syntax Tree (AST) transformation path.
In high-stakes mainframe migration, "hallucination" is not an acceptable failure mode. This module enforces a strict Verification Loop.
Latency Impact
Running the verification loop adds a marginal overhead to the transformation pipeline, but guarantees 100% logic retention.

Integration Logic
When deployed alongside the Mainframe Modernizer, this module sits between the Generation Layer and the Commit Layer.
- Ingest: Raw COBOL code is parsed.
- Transform: AI suggests Java equivalent.
- Audit: XAI Core compares the Control Flow Graphs (CFG) of both.
- Reject: If CFGs do not match, the code is rejected before human review.
