A sensor 1,700 m under the Atlantic gets one visit a year, when a ship can reach it.
If a fault starts to corrupt its results in month two, the bad data can run for ten months before anyone looks.
We recently released Mru Field 0.1.0 for equipment like this. It runs the task as three copies, lets out only results it has checked, and keeps going as copies fail.
It's the same decision code that ran on ESA's OPS-SAT satellite.
