In the Military tech branch, I researched Military Specialization (Defensive Fortifications) which supposedly gives Planetary Defense +10%.  Now when I look at a specific planet, its Planetary Defense still shows 0%.   Does anyone know if the tech bonus is applied "behind the scenes" whenever I'm invaded?

From looking at ThalanTechDefs.xml, I see that this bonus is encoded thus:

      <EffectType>PlanetaryDefense</EffectType>
      <Target>
        <TargetType>Faction</TargetType>
      </Target>
      <BonusType>Flat</BonusType>
      <Value>0.1</Value>

...which appears to make sense, given what little I know about how Stardock encodes techs.  Still, I don't see a way to tell if my planets are getting this bonus or not.  Any help is appreciated.
