'predictably-updated' originates from the combination of 'predictably' and 'updated'. 'Predictably' comes from the Latin 'praedicere', meaning 'to foretell', and 'updated' comes from the Latin 'updatum', meaning 'to bring up to date'.

'predictably-updated' evolved from the need to describe systems or processes that are updated in a regular and expected manner.

Initially, it meant 'updated in a foreseeable manner', and this meaning has largely remained the same in modern usage.
