Overview
RunSeal sandbox provider for DeepSeek Harness, replacing the built-in sandbox with OS-native policy-enforced command execution on Windows/macOS/Linux.
- OS-native sandbox with enforceable filesystem, process, resource, and network boundaries
- Maps dsh sandbox levels (read-only, workspace-write, danger-full-access) to RunSeal policies
- Network modes: unmanaged, disabled, or proxy with credential redaction
- Streaming stdout/stderr and exit code propagation via RPC events
- Fail-closed behavior: missing setup or backend rejects with clear error
- Structured audit events and JSONL audit records for every execution
- Automatic Windows sandbox setup with UAC prompt on first confined execution
- Out-of-tree plugin, depends only on published dsh base packages
