- `JobStart` is a union discriminated by `record`: `RecordingJobStart.run` receives `RecordingJob` (with `append`), `PlainJobStart.run` receives the plain `RunningJob`, and the registry builds the plain face without the method, so the former warn-and-drop path is unrepresentable. - Remove the duplicated JSDoc opener in the registry seam and correct the job-list slot comment (order 20 sits before the subagent catalog's 30). - Restore the `cordis-tool-round` session fixture whose only change was a re-recorded `createdAt`. - Update the 2026-08-08 job-display note's stale service-disposal and slot ordering facts; archive the superseded 2026-08-25 unified-task-list note and point its remaining inbound links at the archived snapshot.

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.
