Life preservation programming

Life preservation programming, or LPP, was a deeply embedded series of commands required by law for every droid manufactured in the Galactic Empire, and before it, the Old Republic.

LPP subroutines functioned as a final stop against behavior that would lead to harming an organic. LPP functioned independently of restraining bolts or other additional devices. They were not a 100 percent effective safeguard, but the likelihood of a droid going rogue was greatly lessened with sophisticated LPP. Manufacturing or selling a droid without life preservation programming was illegal without special government dispensation, but enforcement was lax in the Outer Rim.
