Since some of this code is copy-pasted and then the variables are renamed from Relational (https://github.com/ltworf/relational), every file that was done in this fashion must include the original copyright note, and then add the authors who did the further modifications that happened since then.
See for example commit d333e21bf6dca63153a116b1634e5d7ec6bb9fcc where some of the variables haven't been renamed.
Hello,
Since some of this code is copy-pasted and then the variables are renamed from Relational (https://github.com/ltworf/relational), every file that was done in this fashion must include the original copyright note, and then add the authors who did the further modifications that happened since then.
See for example commit

where some of the variables haven't been renamed.
