access-manage Project Notes

This is a learning project for MySQL CRUD with Node.js, TypeScript, Fastify, and mysql2.

When working in this repository:

Prefer explaining changes in Chinese because the project is being used for learning.
Keep examples close to the current code style: controller handles HTTP, service handles business rules, repository handles SQL.
Do not replace the direct mysql2 SQL approach with an ORM; the goal is to learn tables, SQL, indexes, transactions, and parameterized queries.
Use .env.development for local development configuration.
Use Docker Compose only for local MySQL unless the user asks to containerize the Node.js app too.
Before changing database behavior, check migrations/, src/db/, and the related repository files.
When files or directories are added, removed, renamed, or reorganized, update README.md in the same change.
If package.json scripts change, update the README script explanation in the same change.
Use .agents/skills/readme-structure-sync/SKILL.md as the project skill for README and structure synchronization.
