"""Tests for security test endpoints.

NOTE: These tests were written for the V1 API (single validate/reject
endpoints).  The V2 workflow uses dual Red/Blue validation, different
RBAC roles, and a new state machine.  Integration tests for V2 live in
``test_integration_v2.py`` and ``test_workflow.py``.

Tests in this file that exercise deprecated V1 endpoints are marked as
``xfail`` so they don't block the suite.
