lsdsjy 755b44bbcd fix(headless): require the query service for every --session-id run
Address the ds-review-bot v9 review on PR #3849:

- Require `sessionQuery` before the live fast path too: a later process has no
  live Agent and must find the id through the query service, so a live identity
  no longer bypasses the check.
- Soften the live `stat` comment to what it proves: a stored record rules out an
  in-memory registration, while write-handle ownership is not queryable.
- Complete the `parseArguments` JSDoc and fix the broken English sentence in
  README.md and the Agent Note.

DeepSeek Harness

English | 中文

DeepSeek Harness (dsh) is an open-source agent harness developed by DeepSeek AI.

It is built on an everything-is-a-plugin architecture and powered by Cordis, whose design is described in A Programming Paradigm for Spatiotemporal Composability.

Documentation: https://deepseek-harness.github.io/deepseek-harness/

Developer preview

DeepSeek Harness is in developer preview and iterating rapidly. THERE WILL BE COMPATIBILITY-BREAKING CHANGES.

Review the safety notice before running the project.

Run

Run from npm

Install Node.js, then run:

npx @deepseek-ai/dsh web

The command starts the Web UI at http://127.0.0.1:3080 by default and opens it in the default browser for a local launch. An SSH launch only prints the host URL because the SSH client or editor owns the local forwarded address. Pass --no-open to run the server without opening a browser. See Web UI guide.

Run from source

To run from a repository checkout:

git clone https://github.com/deepseek-ai/deepseek-harness.git
cd deepseek-harness
pnpm install
pnpm run build
pnpm dsh web

pnpm run build prepares the repository artifacts. pnpm dsh web uses those built artifacts without rebuilding.
