Transporter capacity per hub, and research to raise it
Forgejo #20, part 7 of #12 and the last of it. A hub stations BASE_HUB_CAPACITY (2) transporters. Total berths are hubs x per-hub capacity, so building another hub or researching "Freight Yards" both raise it - which is the choice #12 asks the player to make. Capacity follows the same shape as max_fleet_size() (sum a bonus over `unlocked`) rather than being a second mechanism doing the same job, so research applies to hubs already built, not only to ones placed afterwards. A queued-but-unbuilt transporter holds its berth. Without that a player could order ten against two berths and only discover the problem when they refused to appear. Ordering past the cap is refused outright, and the two refusals - no hub at all, versus every berth taken - say which, because "nothing happened" is exactly the bug reported against the craft button.

# Headless gameplay test: run with
|
||||
# godot --headless -s res://tests/test_hub_capacity.gd
|
||||
# Forgejo #20 (part 7 of #12): a hub stations a limited number of
|
||||
# transporters. More hubs, or research, raise it.
|
||||
#
|
||||
# Verifies:
|
||||
# 1. capacity is per hub, so a second hub raises the total
|
||||
# 2. ordering past the cap is REFUSED, not silently swallowed - the ticket
|
||||
# is explicit that the player has to be told
|
||||
# 3. a queued-but-unbuilt transporter still holds its berth, or ten could
|
||||
# be ordered against two and only fail on arrival
|
||||
# 4. researching Freight Yards raises capacity for hubs ALREADY BUILT, not
|
||||
# just ones placed afterwards
|
||||
# 5. the extra berth is immediately usable
