DeepSeek Harness Plugin: Mnemosyne Persistent Memory

The DeepSeek Harness (DSH) plugin Mnemosyne is guided by the core philosophy of "Everything is a plugin," and aims to resolve context memory loss issues in DSH. Maintained by Witchwarren2344, the project is released under the MIT License and is completely free. Mnemosyne provides core capabilities such as permanent memory, vector-based semantic search, LLM reflection, automatic knowledge-page generation, and code mapping. It supports cross-session retrospection, multi-workspace isolation, and delta refresh. Deployment is supported via local Ollama (zero cost) or cloud APIs, and developers can use it with the `mnemo_store` and `mnemo_recall` commands. It serves as a foundational component for building DSH Agents with long-term memory.
