`ProfileRuntime.recompose({ reloadBundles: true })` replaced its profile
before the Loader had accepted the update, so a rejected recomposition left
`current`, `layers`, and `originOf` describing a stack that never mounted.
The user patch watchers took a second path through the launcher's
`composeLive`, which wrote the new conflicts into the failure registry
before the update and kept composing from the runtime's stale profile.
Conflict records shared the registry with row failures under a fabricated
entry id and a group id that meant three different things, so the plugin
inventory attributed a conflict to the layer that won the id, and a bundle
disabled after failing kept its import and apply records forever.
The runtime now holds one committed composition — profile, stack ownership,
conflicts — and publishes a candidate only after `entry.update` resolves;
`originOf` reads the committed owners instead of recomputing them. The
watchers call `recompose` through a `reapply` callback, so every live change
goes through the one entry point. Conflicts live on the runtime with their
messages and never enter `pluginFailures`, whose records name rows that
reached the Loader; the inventory lists them under the layer that lost. A
contained group clears its rows' records when it unmounts.
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.
