 ## OVERVIEW
 Core module provides foundational classes for synchronous (`requests`) and asynchronous (`aiohttp`) captcha solving operations.

 - **Retries**: `tenacity` for async, `requests.Retry` for sync (5 attempts, exponential backoff)
 - **File Processing**: `FileInstrument` handles local files, URLs, and base64 in both sync/async contexts
 - **Session Management**: Instruments maintain their own HTTP sessions with retry adapters

+## ANTI-PATTERNS (THIS MODULE)
+- **Empty `__init__.py`**: Does NOT re-export base classes. Users must import via full path `from python3_capsolver.core.base import CaptchaParams`
