 Production deployment permits unused workspace patches for packages outside the runtime closure; patches for included packages must still apply successfully. This exception is confined to the deploy command; repository installation still rejects unused patches.
 
-From the repository root, `pnpm exec tsx scripts/build-exe-for-python-sdk.ts` verifies the closure, builds packages, deploys a symlink-free tree, packages the selected target, and syncs the executable and sidecars into this module. Only the target platform’s PTY prebuilds are packaged. Package README, CHANGELOG, HISTORY Markdown, source maps, and TypeScript declarations outside runtime assets are omitted. Deployment disables workspace hoisting, and packaging excludes checkout dependencies and workspace source trees outside the deployment so dependency scans cannot add development packages to the payload. Staging shares root workspace packages with nested consumers of the same pnpm dependency identity, preserving singleton services while retaining different peer resolutions. `scripts/build-python-release.py` stages release-shaped wheels at the root repository version and pins `deepseek-harness-sdk` to the exact runtime version.

 The installed-wheel smoke creates a clean virtual environment outside the checkout, proves the installed distribution and executable identities, then exercises default and customized SDK profiles, external plugins, MCP, native tools, direct JSON-RPC, committed snapshots, and the real provider on trusted runs. Its Office scenario relocates the lightweight target payload, explicitly downloads the sidecar, and converts DOCX with the required platform engine: the target’s declared native engine, or WASM when no native engine is declared. See the [Python contributor workflow](../development.md) and [installed-wheel testing decision](../../.agents/notes/implemented/testing/2026-08-23-installed-python-wheel-black-box-ci.md).
