FreeDSH (dsh-h-v1): Free Routing and Security Update Plugin for DeepSeek Harness

FreeDSH is a community-maintained plugin for DeepSeek Harness, designed to mitigate high single-model costs and environment fragility through free-first multi-model routing and local gateway integration. It offers core features including intelligent failover, UI overlays, secure core updates, and versioned overlays. Users can install it on Windows or Linux using the provided commands, or as a Bundle, and rely on snapshot and rollback tools to maintain environment stability. The plugin requires locally managed credentials and is not affiliated with the official DeepSeek team, making it well suited for users focused on cost control and configuration management.
