- - - - 3. "CardGen" async processes DTOs, runs card rule evals, and writes to HS DB
        
        "CardGen" notes
        
        Rules are expressed using SPeL
        
        HS DB is a MySQL db
        
        Only those program rules with DTO changes are re-eval'ed
        
        GetCards op dequeues the MQ
        
        4. HS "Get" API calls receive user's card data payload
        
        HS "Get" API notes
        
        Single JSON response for a user for all their cards
        
        Layercake service fills Card templates with payload data
      - "Data Writer" notes
        
        Message queue uses RabbitMQ
        
        DTOs are essentially status update records written to a message queue
        
        DTOs are tuples like (userGUID, programBlueprintGUID, {status payload})
        
        are constructed from simple joins between Data Lake tables
        
        Each program has its own DTO/s mapped to it
        
        Data Lake is a MySQL db
        
        stores near-real-time data only; updates for the past day at most
        
        HS for the most part doesn't need to do time-series calcs and so can live without historical data; but some new questionnaire+nudges reqs might change this picture
