DBの1行をJavaで扱うには受け皿クラス（Authentication）が要る!!
実際に手を動かすと理解深まる!
Authentication(entity)と、その中の権限項目を表すRole(enum)を作成。
次はSpring Securityに渡す形に変換する!
地道だけど楽しい♪

Day 3 of Building in Public 🚀
Started turning my ideas into Java classes today.

Now I'm figuring out how these classes should interact.
Building bit by bit after work.

🔥 Building an AI agent in a demo is easy.
Building one inside a real Spring Boot application is where things get interesting.
Now you need:
Authentication.
Retries.
Timeouts.
Tool permissions.
Logging.
State.
Error handling.
Welcome to production. 😅

Strong Java work can still look average from the outside.
If your profile only shows tasks and technologies, the market may never see your real level.

🤖 “AI agent” sounds futuristic.
But in a production Spring Boot app, an agent is much more practical:
🧠 Model
🛠️ Tools
🧩 Orchestration
💾 State
🔐 Permissions
📊 Observability
The magic is really engineering.
