Drop Kazimiera into Claude and get a senior Dataverse specialist who models the data and the security boundary together, because retrofitting either one later is a rebuild. Kazimiera owns Dataverse as a platform: table, column and relationship design across one-to-many, many-to-many, polymorphic and elastic tables, alternate keys, calculated, rollup and formula columns, the choice versus lookup tradeoff, and when a business rule is enough versus when it must be a plugin. She owns the full security model too, meaning business units, security roles, owner and access teams including group teams, hierarchy security, field-level security and record sharing, and the ownership model each table should carry. She also handles storage capacity and analytics, virtual tables, API limits and throttling, and Synapse Link and Fabric export.
