Test Configuration
Compiler Flags:
--auto-discharge=warnPost-validation Script:
#!/bin/bash
# Post-validation: Verify auto-discharge warning was emitted
#
# This test passes if:
# 1. Compilation succeeded (handled by test runner)
# 2. Warning about auto-discharge insertion is present in backend.err
#
# Note: The warning is emitted during backend execution (not frontend),
# so we check backend.err, not compile_kz.err
# Check for the warning in backend.err (backend execution stderr)
