Measurement plans and holding check

How a change will be judged is locked, hashed and versioned before the first switch. The holding check looks again later.

How the holding check works

After a verdict, the same measures are checked again on later runs. The result is one of three words: holding, faded or inconclusive. A faded result reopens the change for review; it never undoes a value by itself.
