    "displayName": "Agent-Runtime",
    "position": 5,
    "path": "compute",
    "scope": "Host process and operational runtime for an agent core.",
    "summary": "The runtime hosts an agent process around the core: built-in tools,\ninternal session state, tool registry, hook sockets, approval primitives,\nsubprocess execution posture, streaming, output guards, and runtime\nidentity. Realized by `AgentRuntimeImpl` instances.\n",
    "responsibilities": [
      "Maintain internal session and transcript state.",
      "Provide built-in tools, dynamic tool discovery, hooks, and approvals.",
      "Manage subprocess/tool execution posture and streaming events.",
      "Enforce runtime output, resume, and journal/event contracts."
    ],
    "examples": [
      "LangGraph checkpointer/store, thread state, interrupts, streaming runtime.",
      "Claude Code/Codex/Gemini CLI process runtimes.",
      "a5c unified runtime, Pi-compatible session profiles, agent-mux remote runtime.",
      "Built-in file/shell/search tools, approval gates, session files."
    ],
    "fitNotes": "Frameworks can leave runtime to the host app; CLI products often combine\ncore and runtime in one binary. a5c runtime is modeled as a unified\nsame-layer implementation that can map Pi, Claude, Codex, LangGraph, and\nagent-mux runtime profiles without depending on one of them.\n"
