Evidence
Vendor report
Boundary
It supports checking confirmation, prompt-injection, and destructive-action boundaries for tool agents; it does not generalize unpublished safeguards or one metric to every deployment.
GPT-5.6 Terra: SonarSource's Retest of Code Quality and Security on 4,444 Java Tasks

Evidence
Vendor report
Boundary
It supports discussion of rule hits, defect repair, and security checks in this Java sample, not non-Java repositories, tool permissions, or production defect rates.
