dsh-engineering-control-plane: A DeepSeek Harness Plugin for Engineering Task Orchestration and Release Gates

The `dsh-engineering-control-plane` plugin in DeepSeek Harness adopts a plugin-based architecture to provide governed workflows for agent engineering operations. It transforms tasks into Missions and ensures the auditability of code changes and release validation through unidirectional stage progression, Evidence binding, and Quality Gate configuration. The plugin supports passive or active invocation, uses SQLite for data persistence, and can recover from blocked or rework states. Installation requires a compatible Node.js version, and the plugin executes `test`, `typecheck`, and `build` validations by default. It focuses on engineering governance and integrity checks rather than replacing security scanning, and is suitable for teams with strict process controls.
