  - **OpenVibe.Tools** (`ACTOR_TOOLS_URL`): the catalog, the run API and the page reader, for `find_tools`, `run_tool` and `read_page`. Called as any anonymous caller would.
  - **OpenVibe.Bot** (`ACTOR_BOT_URL`, default `http://127.0.0.1:4630`; empty turns it off): a signed-in person's own robots, for `list_my_robots` and `robot_steps`. Actor calls Bot with its own client-credentials token (audience `openvibe.bot`, `bot.robot.read` + `bot.robot.control`) and `X-OV-Subject` naming the person. Bot answers only for the robot's owner, and only on robots where that owner turned on "Let my OpenVibe.Actor agent drive this robot". Bot's gate, limits and e-stop judge every step. App, agent and service tasks never see these tools.
  - **The Console** (`/console`, plan T17 layer 3): one page for a signed-in person. It has a command box (the ordinary task form) and their running and recent tasks; it refreshes itself while something runs, never while they type. It shows what waits for them: their approvals, and approvals waiting on their own computers. It also shows today's spend against the free tier, their agents, and their computers and robots, read from OpenVibe.Bot as them with a 4 s bound, so a slow Bot never holds the page. Links go to Services, Watch and Codes for the rest. It works without JavaScript (`server/http/console-pages.js`, `test/console.test.js`).
--- **A person's own computers, also through OpenVibe.Bot** (plan T14/T17, contracts 0.166.0): `list_my_computers`, `computer_list`, `computer_read`, `computer_run` (argv, never a shell line) and `computer_write`, on machines installed with OpenVibe Node's `--computer` plugin. Actor calls Bot's machine API with its own token (`bot.computer.control`) and `X-OV-Subject` naming the person. Bot answers only for the machine's owner, and only where that owner turned on "Let my agent use this computer". The level the owner set on the machine decides what may happen there; at `ask`, each run or write waits up to two minutes for the owner's approval on the machine. Only a signed-in person's task sees these tools (`server/agents/computers.js`, `test/computers.test.js`). `computer_screen` (when an OpenAI key is set) takes a picture of the machine's screen through Bot (1280 px wide) and has OpenAI's vision model answer the agent's question about it. The runtime model gets that answer, never the picture; the picture is not stored; secrets visible on screen are named, not repeated; and each look is metered on the task like any model call (refused once the task's budget is spent).

It is an acting command, so at level `ask` each one waits for the person's approval on the machine; the runtime is told to look first, act in small steps, look again, and never type a secret the task did not give it.
  - **OpenVibe.Events** (`ACTOR_EVENTS_URL`): the two ADR-033 subscriptions created at boot, and delivery to the loopback `/internal/events`.
  - **The model providers**: DeepSeek (`ACTOR_DEEPSEEK_API_KEY`, `api.deepseek.com`), OpenAI (`ACTOR_OPENAI_API_KEY`, `api.openai.com/v1`) for the web-search agent and the cross-family check, and an OpenAI-compatible local server (`ACTOR_LOCAL_LLM_URL`) for private mode.
