dsh-context-rollover: A Model-Driven Context Window Rollback Approach

`dsh-context-rollover` is a DeepSeek Harness plugin designed to address the challenges of managing long-conversation context. It takes over the compression engine and provides a model-driven context rollover mechanism, enabling context extension without relying on LLM summarization. The plugin supports locally persisted notes, preserves raw data and the verbatim tail, and offers both manual and automatic rollover capabilities. Users must select a specific preset to enable it and should be mindful of dependency resolution issues on Windows. It is intended for advanced users managing long-term local conversations.
