# Third-Party Notices

DeepSeek Harness is licensed under [MIT](LICENSE). 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 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`](pnpm-lock.yaml) — inspect it with `pnpm licenses list`. The Python closure is recorded separately in [`python/sdk/uv.lock`](python/sdk/uv.lock).

## Vendored source (`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`](vendor/README.md).

## Runtime npm dependencies

External packages that a workspace package resolves at runtime. 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:

- `node-pty@1.2.0-beta.15` — [`patches/node-pty@1.2.0-beta.15.patch`](patches/node-pty@1.2.0-beta.15.patch)

## Official Claude Code platform payloads

The 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 0.3.220 declares the following optional platform packages. Each carries the official Claude Code 2.1.220 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.

## Development-only npm dependencies

External packages **directly declared** only by repository tooling, test infrastructure, the documentation site, the demo leaves, or the native launcher's build workspace. No shipped surface names them itself. A package here may still be pulled in transitively by a runtime dependency — `pnpm-lock.yaml` is the authority on the full closure — so this tier records who declares a package, not what a build ultimately bundles.
