# already have a populated planet in the same system that could build base troopers) and we have at least a
# minimal amount of PP available, and (2) in the second pass we go through the reserved base trooper target list
# and check to make sure that there does not appear to be too much military action still needed before the
# target is ready to be invaded, we double check that not too many base troopers would be needed, and if things
# look clear then we queue up the base troopers on the Production Queue and keep track of where we are building
# them, and how many; we may also disqualify and remove previously qualified targets (in case, for example,
# we lost our base trooper source planet since it was first added to list).
#
# For planning and tracking base troopers under construction, we use a dictionary store in
# get_aistate().qualifyingTroopBaseTargets, keyed by the invasion target planet ID. We only store values
# for invasion targets that appear likely to be suitable for base trooper use, and store a 2-item list.

# entry initially is set to INVALID_ID (-1). The presence of this entry in qualifyingTroopBaseTargets
# flags this target as being reserved as a base-trooper invasion target.
# In the second pass, if/when we actually start construction, then we modify the record, replacing that second
# value with the ID of the planet where the troopers are actually being built. (Right now that is always the
# same as the source planet originally identified, but we could consider reevaluating that, or use that second
# value to instead record how many base troopers have been queued, so that on later turns we can assess if the
# process got delayed & perhaps more troopers need to be queued).
