### Core Principles

**Thread Safety**: `AtomicLong` for counters, `volatile` for status flags, synchronized blocks, thread-local storage via `CrawlingParameterUtil`

**Resource Management**: `AutoCloseable` throughout, `DeferredFileOutputStream` for large responses, connection pooling, background temp file deletion via `FileUtil.deleteInBackground()`
