Day 4 - Synthesis: 4 Domains + End-to-End Scenarios

Final day: integrate all four domains through real test scenarios that blend them.

Integration Map: Four Domains as One Pipeline

Domain 1: DATA           Domain 2: EDA           Domain 3: MODELING      Domain 4: OPS
─────────────────────────────────────────────────────────────────────────────────
Kinesis Streams   →   Clean nulls            Tabular + trees  →      Real-time endpoint
S3 lake           →   One-Hot encode        XGBoost + AMT            Auto-scale
Glue ETL          →   Correlation check     Bayesian tuning          Monitor drift
Athena SQL        →   Distribution plot     F1 (imbalance)           Canary deploy
