# Blast-radius annotation validation for test classes
# Sprint: SPRINT_20260105_002_005_TEST_cross_cutting
# Task: CCUT-005
#
# WORKFLOW PURPOSE:
# =================
# Validates that Integration, Contract, and Security test classes have
# BlastRadius trait annotations. This enables targeted test runs during
# incidents by filtering tests that affect specific operational surfaces.

            Integration, Contract, and Security test classes require a BlastRadius trait to enable targeted incident response testing.
