No formal contract that a host can program against.\n\n## Target State\nHostContract interface with startRun, getStatus, postEffect, subscribe methods. Implementation over existing CLI commands. Exposed via MCP server and HTTP.\n\n## Dependencies\n- None\n\n## Key Files\n| Component | Path |\n|-----------|------|\n| Harness invoker | `packages/sdk/src/harness/invoker.ts` |\n| MCP server | `packages/sdk/src/mcp/` |\n| Adapter registry | `packages/sdk/src/harness/registry.ts` |\n\n## Recommendation\nM1 (Foundation) implementation. Define HostContract interface. Implement over existing CLI. Expose via MCP and HTTP.\n",
