Abstract
A Canton transaction runs on one synchronizer and is rejected at runtime if that synchronizer does not host every stakeholder, has not vetted every package, or cannot receive every input by reassignment, and no pre-deployment tool catches this. CCRE is an open-source pre-flight checker (CLI, DPM component, CI gate) that takes DARs and a synchronizer topology and predicts the router's choice and reassignments, or names exactly what is missing. It lets application teams and operators adopt multi-synchronizer deployments without discovering failures in production; the routing dry-run already works in the [MVP](https://github.com/vickyshaw29/ccre).
