dsh-hypatia: A DeepSeek Harness Memory Plugin Based on the Hypatia Knowledge Graph

`dsh-hypatia` is a memory plugin for DeepSeek Harness (DSH) that leverages the Hypatia knowledge graph to provide models with long-term memory. The plugin runs the Hypatia CLI as a host process, handling complexities such as database orchestration within the plugin, while the model focuses solely on memory proposals. Its core features include recall within the same request, precise project scoping, verified writes, two-stage forgetting, and session support without Bash. Installation requires Hypatia CLI 0.1.4 and Node.js 22.5+, and can be completed via the command line. Configuration supports multiple memory presets, authorization, and recall strategies. The plugin provides tools for memory storage, retrieval, forgetting, and knowledge graph queries, but has a single-process limitation and version requirements.
