A failed EXPECT only sets _metadata->exit_code, and a child that exits with a fixed status of 0 hides that failure from the parent. The child in trace_fown.deny_scope_fown has this problem. Exit with _metadata->exit_code in that child. Do the same in the audit.log_subdomains_off_fork children. They only use ASSERT for now, but this keeps them correct when a check becomes an EXPECT.
