DeepSeek Harness is licensed under MIT. It depends on the third-party software listed below. Each project remains under its own license; nothing in this file changes those terms.
This file lists direct dependencies declared by the workspace and the explicitly disclosed official Claude Code platform payload closure. It is generated from the workspace manifests by scripts/gen-third-party-notices.ts: a pre-commit hook regenerates it whenever a staged file changes one of its inputs, and scripts/gen-third-party-notices.spec.ts asserts in the test lane that the committed bytes match. Deleting a manifest runs no hook, so that case is caught by the assertion instead. Run pnpm run verify-third-party-notices for the standalone check.
The complete npm transitive closure, including the Landlock launcher workspace, is recorded with exact pinned versions in pnpm-lock.yaml — inspect it with pnpm licenses list. The Python closure is recorded separately in python/sdk/uv.lock.
vendor/)The Cordis framework and its foundation libraries are source-vendored into this repository rather than consumed from npm, and republished under the @deepseek-ai scope. All are MIT-licensed; each directory preserves its upstream LICENSE file. Exact upstream commits and local modifications are recorded in vendor/README.md.

External packages installed for runtime use or distributed inside the prebuilt browser artifacts. Browser inputs are resolved through the shipping tsdown and Vite configurations, independently of npm dependency sections. The tier covers every plugin a user can mount from cordis.yml — not only what the dsh CLI, Web UI, and Python SDK runtime load by default.
pnpm applies local patches to the following packages at install time, so shipped artifacts carry modified copies; each patch file is the complete record of the modification:
@electron/osx-sign@1.3.3 — patches/@electron__osx-sign@1.3.3.patch@yao-pkg/pkg@6.21.0 — patches/@yao-pkg__pkg@6.21.0.patchnode-pty@1.2.0-beta.15 — patches/node-pty@1.2.0-beta.15.patchThe project owner authorizes distribution of every version of the official @anthropic-ai/claude-agent-sdk package and the official Claude Code CLI/platform payloads that each version declares through optionalDependencies. This identity-scoped authorization does not classify their declared terms as permissive and does not cover any unrelated runtime package; version, declared-license, and payload-set changes still require the ordinary dependency, lockfile, compatibility, terms, and notices review.
The installed SDK 0.3.263 declares the following optional platform packages. Each carries the official Claude Code 2.1.263 executable; the package identities and versions come from the SDK manifest, while the declared license field is verified against the platform payload installed for the current host.

External packages directly declared for development, tests, types, or tooling, without a runtime installation or browser-build relationship. A package here may still be pulled in transitively by a runtime dependency — pnpm-lock.yaml is the authority on that full closure.
eslint-plugin-sonarjs (LGPL-3.0-only) and lightningcss (MPL-2.0) run only as development tooling; their code is not linked into or distributed with any DeepSeek Harness artifact.
