I didn't work on the attrition system, but I believe it calculates a random chance per ship to take extra damage from the enemy when jumping to hyperspace. Damage repair happens post retreat, so the attrition damage is applied before the repairs; if the ship was damaged enough during the tactical battle that attrition would destroy it, the ship is lost in the retreat. The defender can lower or eliminate the attrition damage with certain heroes, or by having planetary defense weapons on the ground (such as planetary ion cannons).
