MAF Automated Review — Iteration 1

Result: No findings
Scope: full PR (1 commit(s)): 1a427164ba15
Model: gpt-5.6-sol-fast

Overview

This test-only PR verifies that a URL resolved from System.LastMessageText, including a link-local metadata URL, reaches the configured HTTP request handler unchanged without performing a real network request. Existing DefaultHttpRequestHandler coverage independently verifies that the provider authorization callback and transport receive the same canonicalized URL, so the added boundary test does not leave a publishable Critical, High, or Medium concern.

Reviewed the supplied pull-request change set across correctness, security/reliability, architecture, and failure behavior.
No publishable findings remained after source verification for this scope.
