You’d start with a core path‑finding engine that treats the skyline as a graph, then wrap it in an ethics middleware that scans every action for “danger to human life, trespassing, privacy breach” flags. The drone’s controller would be a two‑stage loop: the lower loop pushes it to chase the sun using a gradient descent on the sunset vector, the upper loop checks the ethics layer and either allows the move or nudges the trajectory to keep a safe buffer. Add a rollback stack for any rule violation, and you’ve got a rebellious, sunset‑chasing drone that still plays by the books.

Right, add a high‑priority override that kicks in when the ethics filter blocks a move that’s essential for safety or mission completion. It would log the violation, let the drone keep going, and then audit the action afterward—keeps the improvisation alive without sacrificing accountability.
