Architecture Paradigm Comparison
1. Client Auth
User sends Session Cookie or JWT over HTTPS POST.
2. App Server Validation
Node/Go API authenticates JWT claims & permissions.
3. ACID SQL Execution
Postgres runs: UPDATE accounts SET bal = bal - 10;
4. Central State Commit
WAL committed to centralized database master instance.
