BUG: AttributeError: 'ScreenshotService' object has no attribute '_platform'
Root cause: In __init__, _get_default_save_path() was called BEFORE
_platform was initialized. The method tried to access self._platform
to determine the save path.
FIX: Moved platform detection BEFORE save path initialization in:
- core/screenshot.py
- core/screenshot_secure.py
- core/screenshot_vulnerable.py
Order changed from:
1. self._save_path = self._get_default_save_path() # FAILS - needs _platform
2. self._platform = platform.system().lower()
To:
1. self._platform = platform.system().lower()
2. self._save_path = self._get_default_save_path() # WORKS - _platform exists
This is a common Python initialization order bug where methods called
in __init__ reference attributes that haven't been set yet.
