Artifact Harbor: A Session-Level Artifact Browser for DeepSeek Harness

Artifact Harbor is a local artifact browser specifically designed for DeepSeek Harness (DSH) and integrated into the DSH Web session header. It offers multi-format previews, full metadata display, explainable provenance, and security boundaries (such as strict CSP and path restrictions). The plugin must be built and installed from source, is compatible with DSH v0.1.1-rc.2, and is intended to help developers securely manage and review agent-generated files.
