<CanBeUninstalled>, deviceslot, and cargo space oddities

[AssumedPseudonym]

 RPC advised me to post some unusual behavior I’ve uncovered over here, so I am. There are a few things I’ve run into in the process of trying to make a non-uninstallable weapon:

 — As near as I can tell, <CanBeUninstalled> is not called when a station removes one weapon to make room for another one to be installed.
 — Setting a ship’s maxweaponslots to 1, setting a weapon’s deviceslots to -1, and having a station remove this weapon to install another one results in a ship with more weapons equipped than it has device slots for.
 — With 25 tons of cargo space and an empty hold, buying a weapon and having it installed put a weapon weighing 26 tons in my cargo hold.

 I have another thread up on this over in the Shipyard — http://forums.kronosaur.com/viewtopic.php?f=5&t=6400 — where I go into a bit more depth on what happened.
