A Compress routine is copied to a different versioning model

A fictional maintenance worksheet was written for traditional versioned data with referenced states and delta tables. A new administrator applies the same checklist to branch-versioned data and expects a traditional Compress operation to remove all historical rows. The supplied project also needs a tested recovery path and required retained history. A colleague declares all maintenance complete after the familiar command returns without an obvious problem. Another distinguishes storage models, actual supported maintenance operations, retention obligations and verified query/application results. This written exercise executes no command or database change. It asks why a successful familiar operation cannot establish the claimed cleanup and what evidence should guide a model-appropriate authorized maintenance plan.
