Chinesezjc 28f747d775 test(code-runtime-python): cover the reply-pump closed-loop guard; align setsid docs
The closed-loop reply-pump guard now ships with a deterministic regression test:
a worker thread abandons a binding so its loop closes, the host answers that call
before a later binding, and the pump must survive the closed-loop
call_soon_threadsafe to deliver the later reply (host-gated ordering makes it
deterministic; unguarding the pump hangs the later binding to the wall clock).

Align the quiescence self-description with the shipped setsid limitation:
teardown()'s JSDoc and the Agent Note's Problem line now qualify "no subprocess
outlives the fiber" to subprocesses that stay in the child's process group, with
a setsid()-escape exception pointing at the README. Tighten the setsid-orphan
fixture's self-timeout to 5s and its upper-bound assertion to <4000ms so a failed
deadline backstop is a sharper red. Register the new regression tests in the 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.
