All node commands support `--profile` for multi-instance: service labels `dev.nyxid.node.{profile}` (macOS) / `nyxid-node-{profile}.service` (Linux), config at `~/.nyxid-node/profiles/{name}/`. +- Machine nodes add locally-authoritative `shell`/`files`/`computer` capabilities (all off by default), mandatory signed requests, bounded jobs/files, cua MCP stdio, job-bound service gateway and human-only live desktops. Only owner-turn assistant chat keys can use them; guests never. Specialists store `machine_node_ids` and `saved_login_ids` beside `grants`. Owner settings (`machine_confirm`, single-user saved-login opt-in) are human-only. Browser policies/extension/native host belong to the supervisor; separated children run as `browser` or `agent`. Saved logins are encrypted, write-only, exact-origin fills, with no secret-bearing Debug, logs, audit or tool results. Setup/control watches queue their event transactionally. No extra machine DB reads on unrelated proxy/MCP/turn paths. See `docs/MACHINE_NODES.md` for the binding contract and `docs/NYXID_NODE.md` for setup and warnings. +- Machine exec `services` is an explicit per-job least-privilege declaration (default none), bound as ID+slug on MachineJob, shown on cards/audit and rechecked at gateway execution. Server catalog `inference.wire_protocol` and `git_http` metadata generate the signed SDK/git environment; no node slug mappings. Reuse the shared service visibility resolver and middleware API-key identity constructor. Preserve Content-Encoding with Content-Length through both streaming hops. Non-isolated shell warnings must explicitly mention access to node tokens/signing secrets/stored credentials; recommend the container or `--separate-users`, never refuse solely for owner-machine risk. Container Chromium uses user-namespace/seccomp sandboxing via the shipped profile; every agent/file child sets NoNewPrivs. Human live view uses X11/XTest or ScreenCaptureKit/separate human cua input, at 30 Hz with JPEG dirty rectangles and zero idle payload; agent actions/observations stay on cua. Controller revisions cancel in-flight agent work without locks across I/O. Run extension freshness/unit tests and machine container e2e in PR CI.

Capabilities and terms + +A node's machine access has three independent capabilities: + +| Capability | What agents can do | +|---|---| +| `shell` | Run commands (foreground or as background jobs) and use git | +| `files` | List, read, write and edit files, move files between the machine and the conversation | +| `computer` | Operate the desktop (screens, windows, apps, input) through the cua driver | + +User-facing name: **machine** ("Let agents use this machine"). A node with no +capability enabled behaves exactly as today. + +### D2. The machine's owner opts in on the machine (node-local authority) + +The node's local configuration is the authority for what the machine exposes. +Nothing the server sends can enable a capability. + +- New `[machine]` section in the node config (per `--profile`): + - `shell`, `files` and `computer` booleans, default off; + - `roots`: one or more directories the file tools and command working + directories are confined to. The default is a dedicated workspace directory + the enable command creates, `~/nyxid-workspace` (container: + `/workspace`); + - `computer_mode`: `standard` (default) or `unrestricted` (cua's mode, D7); + - limits with safe defaults: max concurrent jobs (4), max command timeout + (3600 s), output caps. +- CLI (all accept `--profile`): + - `nyxid node machine enable [--shell] [--files] [--computer] [--root DIR]... [--computer-mode standard|unrestricted] [--allow-root]`; + - `nyxid node machine disable [--shell|--files|--computer|--all]`; + - `nyxid node machine status`: what is enabled, roots, cua driver version + and permissions (macOS Screen Recording/Accessibility), and warnings. + - `enable` with no capability flag enables `shell` and `files`. +- The node refuses to enable `shell` or `computer` while running as root unless + `--allow-root` is given, with a warning. +- The node advertises its machine capabilities through the existing node + capability reporting (`NodeCapabilitiesMsg`, `node_owner_service::record_capabilities`): + enabled capabilities, OS, arch, root display names, cua driver version, + computer mode and the cua tool list. Changes take effect when the daemon + restarts or reconnects. +- The server stores the advertised machine profile on the `Node` (additive, + serde-defaulted). It only ever narrows: a request for a capability the node + did not advertise is refused server-side, and again node-side. + +### D3. Who may use a machine (server-side authority) + +- **Callers:** the owner's NyxBot and specialist agents, meaning their assistant + chat keys (NyxAgent conversations, including group member threads), on turns + started by the owner. That is the whole audience the user asked for. Guest + turns (`ChatAuthority.guest`) never get machine tools, at any guest access + level: machine access is the owner's, like SSH. Other API keys, delegated + tokens, relay tokens and service accounts get no machine tools. +- **Which machines:** + - NyxBot may use every machine node the owner can use; + - a specialist may use only the machine nodes granted to it; + - "can use" = the node's owner is the agent's owner, or the node is org-owned + and `org_service::resolve_owner_access(owner, node.user_id)` gives the owner + write access (org admins); + - every call re-checks this live, together with the node being online and + advertising the capability. +- **Specialist grants:** + - a new `AssistantAgent.machine_node_ids`, stored **beside** `grants`, not in + it, for the same rolling-deploy reason as `guest_access`: replicas that + predate it rewrite only `grants`; + - `nyxid__spawn_subagent`, `nyxid__grant_subagent` and `nyxid__revoke_subagent` + accept `machines` (node names or IDs); `nyxid__list_subagents` and the + agent summary show them; + - the agent page's Grants form has a machine picker; + - `PUT /agents/{id}/grants` accepts an optional `machines`, and left-out means + unchanged; + - a specialist calling an ungranted machine gets the existing permission + request flow (`decider: orchestrator`), new kind `machine`, decided by + NyxBot (`nyxid__decide_permission`) or the owner, never granted + automatically. +- **Owner confirmation per node:** a server-side per-node setting + `machine_confirm`: + - `none` (default): no confirmation; + - `changes`: every operation that changes the machine (exec, write, edit, + git fetch/pull/push/clone, file save, computer actions other than pure + observation) needs a single-use action card first, reusing the existing + action-card/acknowledgement machinery of destructive account tools. In chat + apps it is decided with the card's 4-digit code, as today; + - `all`: reads need a card too. + + Only the owner changes it, on the Nodes page, through a human-only route. + NyxBot cannot change it; it can hand out the settings link. + +### D4. Tools + +These are native MCP tools, listed and callable only for chat keys allowed by +D3. They are discoverable through `nyx__search_tools` and described so the +model knows when to use them. Names: + +| Tool | Purpose | +|---|---| +| `nyx__machine_list` | Machines the caller may use: name, id, status, OS, capabilities, roots, computer mode, confirmation setting | +| `nyx__machine_exec` | Run a command. `{machine, command, cwd?, services? (explicit slugs or IDs; default empty), env?, stdin?, timeout_secs? (default 120, max node limit), background? }`. Foreground returns `{exit_code, stdout, stderr, truncated, duration_ms}`; background returns `{job_id}` | +| `nyx__machine_job` | `{machine, job_id, wait_secs? (≤ 60), output_offset?}` → status, exit code, new output since the offset | +| `nyx__machine_job_cancel` | Cancel a job (kills its whole process group) | +| `nyx__machine_list_files` | `{machine, path, depth?, glob?}` bounded listing | +| `nyx__machine_read_file` | `{machine, path, offset?, limit?, encoding? text\|base64}` paginated; binary files as base64 only when asked | +| `nyx__machine_write_file` | `{machine, path, content, encoding?, mode create\|overwrite\|append, expected_sha256?}` returns new sha256 | +| `nyx__machine_edit_file` | `{machine, path, old_string, new_string, replace_all?, expected_sha256?}`: exact-match replace (fails on 0 or ambiguous matches) | +| `nyx__machine_save_attachment` | Write one of this conversation's attachments (e.g. a generated image) to a path on the machine | +| `nyx__machine_share_file` | Attach an image file from the machine to the conversation, so the owner sees it (same rules as tool images: PNG/JPEG/GIF/WebP, ≤ 5 MiB, verified magic bytes) | +| `nyx__machine_computer` | Call one cua driver tool the machine advertises: `{machine, tool, arguments}` | + +- **Output bounds.** NyxAgent hands each result to its model as one string + truncated at 10,000 characters (`docs/chat/08-nyxagent-engine.md`, Tool + images). So results are compact JSON, streams are capped (head and tail kept, + with `truncated` flags and byte counts), and reads, job output and listings + paginate. Hard caps are server-side and node-side. +- **Images.** Screenshots and other images from `nyx__machine_computer` follow + the existing tool-image pipeline: chat keys get a text note plus an owner-only + conversation attachment; pixels never enter the result text. The driver's + accessibility and element state (`get_window_state` and so on) is text, and + that is what the model works from. +- **Where tools appear.** Tool descriptions say machines are the owner's and + that commands run with the node user's full permissions on that machine. + NyxBot's and specialists' instructions mention machines only when the agent + has one. + +### D5. Protocol + +- **Messages.** New node WebSocket messages for machine operations: a request + from NyxID, a final result, and streamed output for jobs. They reuse + request/response routing, cross-replica dispatch (`node_dispatch`) and the + timeout patterns of `ssh_exec`/`ssh_exec_result` and proxy requests. Read + `docs/NODE_PROXY_PROTOCOL.md` and follow its conventions; document the new + messages there. +- **Signing.** Every machine request NyxID sends is signed with the node's + signing secret, bound to request ID, node ID, operation and a digest of the + parameters, with a timestamp and nonce the node checks (replay window). The + node rejects unsigned, stale or replayed requests, even when + `NODE_HMAC_SIGNING_ENABLED` is off for proxying. +- **Negotiation.** Nodes and servers that predate this ignore it. The server + only sends machine requests to nodes that advertised machine capabilities. + The node only accepts them when locally enabled. + +### D6. On the machine (node agent) + +- **Process model.** + - Commands run as the node's OS user, never elevated, through the platform + shell (`sh -lc` on Unix, PowerShell on Windows if the node supports Windows), + with no TTY and stdin closed unless given. + - Each command gets its own process group. A timeout or cancel kills the + group (SIGTERM, then SIGKILL after a grace period). + - Background jobs are bounded (max concurrent, retained 1 hour, output ring + buffer), and survive a WebSocket reconnect but not a daemon restart. +- **Environment hygiene.** + - Child processes get a clean environment: an allowlist (PATH, HOME, USER, + LANG/LC_*, TERM=dumb, SHELL, TMPDIR) plus request-provided `env`, bounded. + - They never inherit NyxID or node secrets: tokens, signing secret, keychain + or credential-store paths, `NYXID_*` variables. + - File tools refuse the node's own config/credential directories even inside + a root. +- **Roots.** + - File tools and `cwd` must resolve inside a configured root: canonicalized, + symlinks resolved, no `..` escape, TOCTOU-safe opens (`O_NOFOLLOW` or + re-checks) where the platform allows. + - Writes are atomic (temp file plus rename) and keep existing permissions. + - `expected_sha256` gives optimistic concurrency. + - The shell itself can reach anything the node user can. That is what `shell` + means, and `status`, docs and the UI say so plainly. +- **Git and other connected services** go through the machine's service + gateway (D14). No credential is ever sent to the machine. +- **Transfers.** `save_attachment` streams the attachment from NyxID + (owner-only, same conversation, size-capped). `share_file` streams a verified + image into `assistant_attachments` (≤ 8 per turn, existing rules). + +### D7. Computer use through the cua driver + +- **What it is.** The cua driver (MIT, Rust, `libs/cua-driver` in trycua/cua) + exposes GUI tools over MCP stdio (`cua-driver mcp`): screenshots/desktop + state, window state with snapshot-bound elements, click, type, keys, scroll, + drag, apps, windows, clipboard and so on (28 tools in the pinned 0.30.4 contract). + It has no shell tools; ours cover that. +- **Managed install.** + - `nyxid node machine enable --computer` installs a pinned cua driver release + into the node's own directory. The download must be verified against + SHA-256 values pinned in NyxID for each supported platform; there's no + trust-on-first-use. + - Alternatively, `--cua-driver PATH` uses an existing binary; its version is + checked. + - Never install or enable the optional `cua-perception` extension (AGPL). + - Turn off cua telemetry. +- **Running.** + - The node starts `cua-driver mcp` lazily on the first computer call, keeps + one session, restarts it if it dies (bounded), and relays `tools/call`. + - The advertised tool list comes from `tools/list`, filtered to the driver's + public contract. + - macOS: guide the owner through Screen Recording and Accessibility grants + (`status` shows them). Linux needs a display; the container image provides + one. +- **Permission mode.** + - `computer_mode` selects cua's permission mode at launch (never over the + tool protocol). + - `unrestricted` needs the explicit flag, prints cua's own warning, and is + the default only in the machine container image (D8), which is disposable. + - In `standard` mode, actions cua reserves for human consent are refused on + an unattended machine; the result says so. + +### D8. Easy install on a host, a remote VM or a container + +- **Host or VM:** the existing installer plus one setup command. The one + command registers, enables the chosen capabilities, installs computer use if + asked, and installs and starts the daemon (launchd/systemd, `--profile` + aware): + + ``` + nyxid node setup --token nyx_nreg_… [--machine] [--computer] [--root DIR] + ``` + + `nyxid node register` and `daemon install` keep working as today. +- **Container:** a new image, `nyxid-node-machine`, published next to the + existing node image by the Publish Images workflow. Remember that Dockerfiles + stage workspace members by hand. It contains: + - Ubuntu LTS, a non-root `agent` user, and a `/workspace` volume; + - Xvfb with a light window manager; + - the pinned cua driver, `computer_mode = unrestricted`; + - git, curl, ca-certificates, python3, nodejs, ripgrep and build tools; + - the node agent. + + On first start it registers with `NYXID_NODE_TOKEN` and persists its identity + in a volume. `nyxid node docker … --machine` uses it. +- **Web (Nodes page):** + - An "Add a machine" flow with tabs for this computer, a remote VM and Docker. + It mints a registration token through the existing register-token API and + shows the exact commands. + - A plain safety note: use a VM or container, not your personal computer. + Agents act with that user's full access, and prompt injection is possible. + On a non-separated machine, commands can read the node token, signing + secret, config and locally stored credentials. Setup, Nodes and machine + status say so explicitly, with a persistent Not isolated badge when shell + is enabled. Recommend the container or `--separate-users`; proceeding + remains the owner's choice. + - Node details show machine capabilities, roots, computer mode, the + `machine_confirm` setting, and which agents may use the machine. +- **NyxBot:** leads the whole setup from chat (D13). + +### D8a. Out of scope for this release + +Interactive TTY sessions and Windows containers. Write these down as follow-ups; +do not half-build them. + +### D13. NyxBot sets machines up: it must be a breeze + +The user: "nyxbot need to help user to set up this, so setting up should be a +breeze". The owner says "set up a machine for coding" (in the app or in a chat +app) and NyxBot takes it from there. Setup never exposes a credential to the +model: a registration token in the model's context would let a prompt injection +register an attacker's machine as the owner's, and agents would then send it +commands and files. So registration tokens appear only on NyxID pages the +owner opens, or on the machine itself, never in tool results or the transcript. + +**Two ways in, both driven by NyxBot:** + +1. **Setup link.** NyxBot calls `nyxid__machine_setup_link`: + - Arguments: `{name?, where: this_computer | vm | docker, capabilities?, grant_to?: specialist name or id}`. + - It returns a link to a one-page setup at `/machines/new?...` with the + choices prefilled, like `nyxid__channel_bot_setup_link`. + - On that page, the owner: + - reviews the choices, including "let use it" when `grant_to` + is given; + - reads the safety note; + - gets a single copyable command with a fresh single-use setup token: + - host or VM: one line that installs the CLI if missing and runs + `nyxid node setup` with the token and the chosen capabilities; + - Docker: one `docker run` with the token in an env var. + - The page shows live progress: waiting for the machine, connected, and each + enabled capability. When done it links back to the chat. +2. **Pairing code**, for a machine the owner is already logged in to, e.g. + over SSH: + - The owner runs `nyxid node setup --machine [--computer]` with no token. + The machine prints a short code and a link, `…/machines/pair?code=…`, as + in the device-login flow (`docs/DEVICE_LOGIN_PROTOCOL.md`). + - To approve, the owner opens the link (the page shows the machine's + hostname, OS, IP and requested capabilities, and requires an explicit + confirm), or tells NyxBot the code. + - If told the code, NyxBot calls `nyxid__machine_pair { code }`. That raises + an action card showing the same machine details, which only the owner can + decide (code-quoted confirmation in chat apps, as for other cards). + - The code alone grants nothing. Until approved, the machine holds no + credential and receives no requests. + - The container image uses this when started without a token, printing the + code and link in its logs. + +**After connection:** +- **Watch.** Both paths are watched (`nyxbot_watches`, as for channel-bot setup + links). When the machine registers and reports its capabilities, the waiting + NyxBot thread is woken with a "machine connected" event. +- **Follow-up.** NyxBot can then confirm with `nyx__machine_list`, run a + harmless check (e.g. `uname -a` / `git --version`), grant the machine to the + specialist the owner named (the setup page's choice, or a normal grant), and + continue the task. +- **Guidance.** NyxBot's instructions describe this flow, recommend a VM or + container over a personal computer, and explain in one sentence what each + capability allows. For computer use it tells the owner about the macOS Screen + Recording/Accessibility prompts. +- **Failures.** They are reported back to the thread: + - the setup expired; + - the pairing was declined; + - cua permissions are missing; + - the machine is offline. + +**Mechanics:** +- **Setup tokens.** Setup-link tokens reuse the node registration token + machinery. They are single-use and short-lived, and carry the capabilities + and grant intent. Only hashes are stored. +- **Pairing codes.** Pairing codes follow the device-code patterns already in + the codebase: HMAC-stored codes, rate limits, expiry, and approve/deny racing + atomically. +- **Result.** Both paths end in the same node registration as today, plus + machine enablement on the node and the optional specialist grant. + +### D14. Connected services from the machine: git, SDKs, scripts, CLIs + +The user: "the git command and stuff can also be from the github service they +have connected on nyxid, and other services". Commands agents run on the +machine can use the owner's connected NyxID services (GitHub for `git`, OpenAI +for an image-generation script, any other connected service through its API) +**without the machine ever holding a credential**. Credentials stay in NyxID, +calls are audited, billed and approval-checked exactly like the agent's MCP +calls, and revoking a connection works immediately. + +**Gateway:** +- **Least privilege per job.** `nyx__machine_exec.services` explicitly declares + the services this command needs. NyxID validates slugs/IDs against live key + access and stores both ID and slug on `MachineJob`. Omitted/empty means none. + Every gateway call must match that declaration and remain accessible to the + key. An undeclared request says to declare its service on `nyx__machine_exec`. + Machine confirmation cards and audit records list those services. +- **Where it listens.** The node runs a service gateway on loopback only + (`127.0.0.1`, an OS-assigned port), for the commands and jobs it starts. +- **Per-command token.** Each command or job gets a fresh random gateway token + in its environment. The token is local to the node and meaningless to NyxID. + It maps to that job and expires when the job ends. Requests without a live + token are refused. +- **Forwarding.** Requests to `$NYXID_GATEWAY_URL/s/{slug}/{path}` are forwarded + over the node's WebSocket as a node-signed "machine service call" and + streamed back. Streaming responses and large downloads are streamed, not + buffered. `Content-Encoding` and `Content-Length` are forwarded together on + both relay hops; compressed SDK and git responses keep their original bytes. +- **Server-side execution.** NyxID runs the call through the existing proxy + pipeline (`execute_proxy`) with the identity and authority of the chat key + whose machine operation started that job: NyxBot's services, or the + specialist's grants. That covers service allowlists, approvals, billing, + node routing of node-held credentials, the platform-key ACL and audit. +- **Server-side checks.** NyxID honours a service call only when it names a + job that NyxID itself started on that node, for that conversation, and that + is still running. A compromised or rogue machine therefore cannot call + services for another conversation, another agent or after the job. +- **Guests.** Guest turns never start machine operations, so they can never + reach the gateway. + +**Environment for commands:** +- **Always set:** `NYXID_GATEWAY_URL` and `NYXID_GATEWAY_TOKEN`. +- **Also set for commonly used SDKs**, only for services declared for this job: + - `OPENAI_BASE_URL` / `OPENAI_API_KEY`, pointing to the gateway; + - the equivalents for Anthropic and other `llm-*` catalog services whose SDKs + honour a base URL; + - the API key variable is set to the gateway token, which is useless outside + this job. +- **Catalog is authoritative.** The server derives SDK variables from + `inference.wire_protocol`, and git rewrites from catalog `git_http.origin` and + `git_http.username`. GitHub OAuth/PAT seeds declare `https://github.com` with + `x-access-token`. The signed exec request carries the environment spec; node + releases contain no service-slug mappings. Git requires a non-platform + connected credential. Discovery reuses the shared catalog/MCP ACL resolver, + and execution reuses the middleware's API-key authority constructor. +- **Visibility.** `nyx__machine_list` shows which connected services are + reachable from the machine and which environment variables are set. + +**Git over the gateway:** +- **Remote side.** NyxID gains a git smart-HTTP route for connected git hosts: + GitHub is required, and GitLab/Bitbucket follow if they are in the catalog. + It forwards `info/refs`, `git-upload-pack` and `git-receive-pack` to the + host (e.g. `https://github.com/{owner}/{repo}.git/...`) with the owner's + connected credential injected server-side as the host expects (GitHub: + Basic `x-access-token:`). The same credential resolution, ACLs and + audit apply, and platform keys are never used. Request and response bodies + stream; the route must handle multi-GB clones and pushes within the existing + proxy body limits, raising them for this route only if needed and + documenting it. +- **Machine side.** + - For each command, the node points git at the gateway through per-process + configuration only: `GIT_CONFIG_COUNT`/`GIT_CONFIG_KEY_n`/`GIT_CONFIG_VALUE_n` + for `url./git/github.com/.insteadOf https://github.com/` (and + `git@github.com:`), plus the gateway token as an extra header for that + URL. + - Nothing is written to global or repo git config. + - Remote URLs in cloned repos stay `https://github.com/...`. + - So plain `git clone`, `fetch`, `pull` and `push` of private repos just work + inside any command declaring the connected GitHub service in `services`. + - With no git host declared, git goes direct, and public repos + still clone. +- **Pushing.** A push goes through the approval pipeline like any other + service write. With `machine_confirm = changes`, the command that pushes + already needed a card. +- **The GitHub CLI and other API tools.** Use the REST API through the gateway + (`curl -H "Authorization: Bearer $NYXID_GATEWAY_TOKEN" + $NYXID_GATEWAY_URL/s/api-github/...`). Document this for agents. Do not + hand CLIs a real token. + +**Failures:** a service the agent may not use, one that isn't connected, or one +that needs approval. The gateway returns a clear HTTP error with the NyxID error +code and message, and the tool result shows it. NyxBot can then offer a +connect link or a permission request, as for MCP service calls. + +### D15. Live desktop: watch the agent, take over, hand back + +The user: "best is if the node can help to stream the desktop or browser etc +back to nyxbot so it can be controlled or watched on nyxbot on the web like +grok bot, muse …, which with the cua it can pass to user if require like +logging to a website and then hand back the control to nyxbot". + +**What the owner sees** +- In NyxBot on the web, a conversation whose agent uses a machine's `computer` + capability shows a **live desktop panel**: + - it streams the machine's screen in near real time; + - it shows the agent's cursor and actions as they happen; + - it can be expanded or popped out. + The Nodes page can open the same view for any computer-capable machine. +- **Controls:** + - **Take control** switches the controller to the owner. The owner's mouse, + keyboard (including typing and shortcuts), scroll and clipboard paste in the + panel drive the machine. + - **Hand back** returns control to the agent, with an optional note (e.g. + "logged in"). + - **Stop** stops the agent's turn (existing Stop). + +**Agent asks for the owner (handoff)** +- **The request.** A new tool, `nyx__machine_request_control {machine, reason}`, + lets the agent ask the owner to take over, for a login, a CAPTCHA, a payment + confirmation or anything the agent should not do. It raises a visible request: + - in the web conversation, a banner or card: "NyxBot needs you on : + " with a **Take control** button; + - in chat apps, a message with a link that opens the live panel (owner web + session required); + - a push notification where configured. +- **While waiting.** The agent's turn ends, and it does not burn a turn polling. + When the owner hands back, the waiting thread is woken with an event turn + carrying the owner's note, as in the existing watch/wake patterns. If the + owner takes control on their own initiative, the agent is paused the same + way and woken on hand-back. + +**While the owner is in control** +- **The agent is fully locked out.** Every `nyx__machine_computer` call, and any + other machine call on that machine that would observe or act on the desktop, + returns `owner_in_control` with instructions to wait. +- **Privacy.** Nothing the owner types, and no frame captured while the owner + is in control, is ever stored, attached, logged or given to the agent. + Passwords typed during a login never reach the model. After hand-back, the + agent observes the resulting state fresh. +- **Commands.** Shell and file operations on that machine are also refused + while the owner has control, since they could observe the session. Other + machines are unaffected. + +**Streaming mechanics** +- **Node side.** + - Agent actions and observations use cua MCP. The human live view uses + in-process X11 capture on Linux and ScreenCaptureKit on macOS (the same + Screen Recording permission). Linux owner input uses a separate XTest + connection; macOS uses a separate human cua session. + - Capture runs at 30 Hz with changed 64-pixel tile detection, merging dirty + tiles into a JPEG rectangle. Idle screens send no frames. Each rectangle + identifies its base sequence; missed frames request a fresh complete frame. + Cap dimensions at 1920×1200 and traffic at 2 MiB/s. At 1280×800, acceptance + is ≥15 fps during activity (aim 24–30), p95 owner input-to-frame ≤100 ms. + - No controller/session lock is held across capture, encoding or input I/O. + Takeover flips a revisioned cancellation signal immediately, kills the + in-flight agent cua session and command groups, cancels file workers, and + discards late results. Target ≤150 ms even with a slow action/file transfer. +- **Transport.** + - Frames and input events travel as binary WebSocket frames tagged by a + desktop-session ID, over the node's existing WebSocket to NyxID. + - NyxID relays them to the owner's browser over an authenticated WebSocket + under `/assistant/nyxagent/...` (human-only, owner-only; add it to + `delegated_read_denied_path` if it is a GET upgrade). + - Cross-replica: follow the existing browser SSH terminal (`/ssh/{id}/terminal`) + and node dispatch patterns, so the browser and the node can be on different + replicas. +- **Sessions.** + - Desktop sessions start on demand (the panel opens, or the agent uses + computer tools) and end when no viewer and no agent activity remain, after + a short idle timeout. + - Several owner tabs may watch; only one controller at a time. + - Bandwidth and frame caps apply per session. +- **Browser.** The machine container image includes Chromium, run as the + node-managed browser of D16 with a persistent profile in the machine volume. + Chromium's renderer sandbox is enabled through user namespaces and seccomp; + the container uses NyxID's narrowly extended Docker seccomp profile with + `--security-opt seccomp=...`, no added capabilities and no `--no-sandbox`. + All dropped children set `PR_SET_NO_NEW_PRIVS` before exec. + Agents can browse, and the owner can take over web logins in it. Sign-ins + persist across tasks, so the owner logs in once, not every time. +- **Audit.** Metadata only: session start and end, control changes and the + reason given by the agent. No frames, keystrokes or clipboard contents. + +**Tests** +- Controller state machine: agent → owner → agent, the agent locked out while + the owner controls, wake on hand-back, owner-initiated takeover. +- Frames during owner control are never persisted or returned to agents. +- Auth: only the owner, never guests or other users. +- Cross-replica relay. +- Frame diffing and rate limits. +- Frontend panel: watch, take control, hand back, request banner. +- An end-to-end run in the machine container: stream, owner types into a + browser field, hand back, agent continues. + +### D16. Saved logins: agents sign in without ever seeing the password + +The user chose to add this in this release, after comparing OpenAI's dots +("Dots sign in with saved passwords without exposing them to the model"). The +agent signs in to websites on the machine using logins the owner saved in +NyxID. No password, one-time-code secret or username value ever enters the +model's context, a tool result, a transcript, a log, an audit record or the +machine's disk. Owner takeover (D15) stays available for everything else. + +**Saved logins (NyxID)** +- **Model.** A new collection of saved website logins with: + - an owner (a person, or an org, managed by org admins through + `resolve_owner_access`); + - a label; + - allowed origins (exact `https://` origins, e.g. `https://github.com`, + `https://accounts.google.com`); + - the username, password and optional TOTP secret (entered raw or as an + `otpauth://` URI), all envelope-encrypted with `EncryptionKeys`; + - timestamps and last use. +- **Management.** + - Owner CRUD on a new **Saved logins** page, through human-only routes. + - Secrets are write-only: the API never returns them, only the label, + origins, a masked username hint and whether a password and TOTP are set. + - Replacement is atomic. + - Deleting the owner purges the owner's saved logins. + - Secret-bearing structs have redacted `Debug` and use `Zeroizing`. +- **Who may use a login.** NyxBot may use all the owner's saved logins. + Specialists may use only the logins granted to them: + `AssistantAgent.saved_login_ids`, stored beside `grants`. The grant tools and + the Grants form accept logins, and an ungranted login raises the usual + permission request. Guests never can. +- **NyxBot's role.** It sees labels and origins (in `nyx__machine_list` or a + small `nyx__saved_logins` listing), never values. It sends the owner to the + Saved logins page through `nyxid__settings_link` (new area `saved_logins`), + and never asks for passwords in chat. + +**Signing in (machine)** +- **The tool.** `nyx__machine_fill_login {machine, login, field: username | + password | one_time_code}` fills the currently focused field of the node's + **managed browser** with that value. The agent navigates and focuses fields + with the computer tools as usual, then submits the form with a click or key. + The result is only `{filled: , login:
