Overall, everything is clear and well-explained.
However, you lost me in section 4.4. The basic information in the first two paragraphs is fine, and reiterates concepts that have already been touched on. However, the placement of infrastructure was too much information to decode at this point in the rules. Critical confusion points included: very specific instructions with not-yet-familiar terms ("an infrastructure operation during the Special Operations phase"), reference to infrastructure moving from warehouses to districts (how does infrastructure get into a warehouse?), and the fact that these actions are out of step with my current turn order focus (in my head, I'm building an understanding of the placement of teams in the human resources phase, while the building of infrastructure is going to take place two phases later). Consider moving section 4.4 or simplifying the infrastructure placement description at this point in the rules.
In the note at the end of 4.7, it's a little difficult to pinpoint the meaning of "in this way" because of the intervening example, and the fact that Carana has two special rules for moving supplies in this section. Move the note into the appropriate paragraph, or replace "in this way" with something more specific ("Carana may only exchange supplies with other players at the port, as this is...")
