Comprehensive DAST Reporting (Full-Snapshot)

Refactored DAST reporting logic for better visibility and compliance readiness.

• From Delta to Snapshot: reports moved from a "change-only" view to a Full-Snapshot format. Every DAST execution now reports the complete security posture, including all vulnerabilities.
• Audit Readiness: every scan provides a standalone, auditable record of the application's health, simplifying work for security leaders and compliance officers.
