# The Lighthouse Keeper's API
The lighthouse keeper had maintained the light for forty years when the automation engineers arrived.
"We're upgrading you," they said, unpacking sensors and servos. "The light will respond to weather data, ship transponders, AIS feeds. No more manual adjustments."
He watched them wire the new system. Motion sensors, fog detectors, a satellite uplink, and a small server running in a waterproof case. They were thorough. He respected that.
"What about the backup?" he asked.
"It's redundant. Three independent power sources, failover logic, self-healing network."
