Sometimes when reading the description of a tech I wonder what exactly will be affected by it.
I am creating this issue after trying to figure out if 'Farimba' affects camel riders or not (in the description we see that it affects 'Cavalry'). Another popular confusion is the blacksmith armor lines and ranged mounted units.
I would suggest to add a list of tech ids for every unit and building in the data.json since the other direction of the relation is far less important.
