About overlapping context challenge, if an instance always exist in both systems. You can choose what system is master for what context (attribute). Source the “Name” from one system and the “Address” from the other system, even if both attribute exists in both system. But it means you need to understand the IT landscape data movement and Business Processes purposes and that is to hard for most people. So sourcing all and hope for the best is pretty normal approach
Nice post again! In this post you completely take for granted that a data vault model will be used (no objections from my end). you may want to link to your earlier Data Vault Modeling Patterns (and from there to this one?).
