#Flow Chart (Detailed)

[Client picks capability namespace]
   -> [Identity | Game | Rewards | Market | Stats]
   -> [Build request payload + headers]
   -> [Backend validation + auth policy]
   -> [Service handler execution]
   -> [DB / chain / index interactions]
   -> [Normalized response envelope]
   -> {4xx/5xx?}
      -> Yes: [Classify error and apply retry/backoff policy]
      -> No: [Persist state and continue next workflow step]
