Prebuilt system primitives: a Linux Landlock launcher and asynchronous POSIX flock through stable Node-API

Local process-sandbox backends for the DeepSeek Harness sandbox seam: bwrap, the npm-distributed landlock-run launcher, macOS Seatbelt, or the Windows ACL restricted-token runner — functionally probed, fail-closed

The dsh SDK profile bundle: stdio JSON-RPC serving and process lifecycle over dsh-base

Agent-plane presentation selector: composes one agent's tools as Code Mode, native, or both


The dsh one-shot bundle: a direct core Agent/Session runner over dsh-base with no Host, HTTP, or browser layer



The shared dsh core as a profile bundle: every profile's first patch layer, inserting the base plugin rows over the empty profile root



Sandbox-consuming implementation of the DeepSeek Harness PowerShell executor seam (confines every command via ctx.sandbox, reports denial/enforcement result facts)

Abstract workspace-directory picking seam (ctx.directoryPicker) for the DeepSeek Harness web GUI host


The core test runtime that executes on React Native devices, providing Jest-compatible APIs (describe, it, expect) and managing test collection, execution, and result reporting in native environments.

The dsh ACP profile bundle: automation-only JSON-RPC stdio and process lifecycle over dsh-base

Token-meter-driven compaction policy and LLM summarization backend for the DeepSeek Harness


Core platform abstractions for React Native Harness
