Context retrieval for DeepSeek Harness: ranks docs, code and media by relevance into a sidebar Context Pack. Lexical and fully local by default. Hybrid is off until you configure a provider; it sends your query and file titles/summaries, not bodies.

One chat for everything in DeepSeek Harness (DSH): no more hunting for old conversations. Each message goes to the topic it belongs to, with its own context.

Branch from any answer and keep branching at any depth. Recursively isolated follow-ups that leave the main DSH task untouched.
