Why dredging is part of trade
Channels silt in, and dredging is what keeps them deep enough for the ships trade wants to use.

From the opening
Rivers and tides drop silt in channels and alongside berths, so the depth a port advertised is not a depth it keeps by doing nothing. Dredging removes that material, or deepens a channel on purpose, and the ships that can call depend on the depth that work maintains. The opening covers silt steals controlling depth, maintenance dredging puts it back, and capital dredging deepens the cut.
The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.
