Python packages for driving DeepSeek Harness as a subprocess. The client SDK communicates with the bundled runtime over newline-delimited JSON-RPC on stdio.
The SDK starts the matching bundled runtime unless the caller selects an explicit channel. The client selects the channel and supplies default configuration; the runtime itself always requires an explicit configuration. The [SDK reference](sdk/README.md) and [runtime carrier reference](sdk-runtime/README.md) own the complete runtime-selection and configuration contracts.
The [Python contributor workflows](development.md) cover building runtime artifacts, validating the packages, source-mode development, and distribution.
