-## 📝 Migration Notes
-
-### Important FastAPI Concepts to Remember:
-
--   FastAPI uses async/await by default (but sync functions work too)
--   Automatic request/response validation with Pydantic
--   Built-in OpenAPI documentation
--   Dependency injection system
--   Type hints are crucial for FastAPI functionality
-
-### Common Gotchas:
-
--   FastAPI doesn't have built-in session support (use external library if needed)
--   Template responses need explicit media_type for HTML
--   Static file mounting needs to be configured explicitly
--   Request object structure is different from Flask
-
-### Performance Considerations:
-
--   FastAPI is generally faster than Flask
--   Consider using async functions for I/O operations
--   Use background tasks for long-running operations
--   Implement proper caching strategies

+# AniWorld FastAPI Refactoring Instructions
+
+This guide details the steps for refactoring `fastapi_app.py` to improve modularity and maintainability, following project and Copilot conventions.
+
+---
+
+## 1. Move Settings to `src/config/settings.py`
+
+**Goal:**  
+Centralize configuration logic.
+
+**Steps:**
+
+3. Update all imports in `fastapi_app.py` and other files to:
+    ```python
+    from src.config.settings import settings
+    ```
+4. Ensure `.env` loading and all environment variable logic remains functional.
+
+---
+
+## 2. Move API Endpoint Code to Controllers
+
+**Goal:**  
+Organize endpoints by concern.
+
+**Steps:**
+
+1. Create controller modules in `src/server/controllers/`:
+    - `auth_controller.py` (authentication endpoints)
+    - `anime_controller.py` (anime endpoints)
+    - `episode_controller.py` (episode endpoints)
+    - `system_controller.py` (system/config/health endpoints)
+    - `setup_controller.py` (setup endpoints)
+2. In each controller, define a FastAPI `APIRouter` and move relevant endpoint functions from `fastapi_app.py`.
+3. Import and include routers in `fastapi_app.py`:
+    ```python
+    from src.controllers.auth_controller import router as auth_router
+    app.include_router(auth_router)
+    ```
+    Repeat for other controllers.
+4. Remove endpoint definitions from `fastapi_app.py` after moving.
+5. Ensure all dependencies (e.g., `get_current_user`, models, utilities) are properly imported in controllers.
+
+---
+
+## 3. General Clean-Up
+
+-   Remove unused code/imports from `fastapi_app.py`.
+-   Confirm all endpoints are registered via routers.
+-   Test application startup and endpoint accessibility.
+
+---
+
+## 4. Coding Conventions
+
+-   Use type hints, docstrings, and PEP8/black formatting.
+-   Use dependency injection (`Depends`) and repository pattern.
+-   Validate data with Pydantic models.
+-   Centralize error handling.
+-   Do not hardcode secrets/configs; use `.env`.
+
+---
+
+**Summary:**
+
+-   `Settings` → `src/server/config/settings.py`
+-   Endpoints → `src/server/controllers/*_controller.py`
+-   Main app setup and router wiring remain in `fastapi_app.py`
+
+---
+
+## 5. Tests (new)
+
+Add unit tests under `src/server/tests/`. Only write tests for:
+
+-   Settings loading/validation
+-   Controllers (basic router contracts, inclusion, and minimal runtime sanity)
+
+Guidelines:
+
+-   Use `pytest`.
+-   Keep tests deterministic: mock env-vars with `monkeypatch`.
+-   Controllers tests should not rely on external services — use `fastapi.TestClient` and import controller `router` objects directly.
+-   When the exact setting fields or route paths are unknown, provide templates and TODOs. Update templates to match real field names / route names.
+-   Run tests with:
+    ```
+    pytest -q src/server/tests
+    ```
+
+Example test templates to add (place and adapt as needed):
+
+-   settings test template: `src/server/tests/test_settings.py`
+
+    -   Checks that `settings` is a Pydantic BaseSettings-like object and that environment variables affect values. Replace placeholder names with real fields from your `Settings` class.
+
+-   controllers test template: `src/server/tests/test_controllers.py`
+    -   Imports controller modules, ensures each exposes a `router`, that the router has at least one route, and that routers can be included in a FastAPI app without raising.
+
+Add these templates and update TODOs to match your actual codebase.
