 - The combat schematic HUD uses typed runtime catalog weapon facets for its

+  Hull and item durability percentages use typed max durability before falling

   Runtime weapon behavior still owns ammo counts, active range, cooldowns,
   temperature, and durability display until those session facts have typed
