Settings → Integrations gets an EAS Simulator row next to SSH device hosts. An EAS host belongs to one environment, because that environment's server holds the Expo credential and starts the sessions.

The editor sets:

  • the host's name;
  • an optional Expo access token (a secret setting; without one the server uses EXPO_TOKEN, then its eas login);
  • the EAS project sessions run under, or "From the thread's project";
  • the session bounds.

Account check. The editor checks the Expo account as it opens and again on Check account, through a new device.easAccount RPC (settings-write scope). It reports who the credential signs in as and where the credential came from, and lists the projects it can use for the picker, so a saved project shows by name and a rejected token shows before anything changes. Only the latest check's answer is shown; a cleared token is checked as empty, so the check does not fall back to the stored token Save is about to drop. A failed check is a DeviceEasAccountError (no cause, since it reaches the browser) whose reason is the credential errors' own guidance or a category for what Expo answered (a rejected credential by status, a refusal, no answer), never Expo's text; not a host error. Editing a saved host says that saving restarts it, which stops its running sessions, and the section says the same of removing one. When a draft cannot be saved (an idle limit not smaller than the session limit, a cleared field), the editor says why.

Device state says supportsEasHosts, and Settings shows the EAS section only for servers that set it: a server from before EAS hosts ignores easDeviceHosts, so a save there would vanish.

Device setup names an EAS host instead of reporting Xcode when only the cloud can run iOS.

Part of built-in EAS Simulator support (stack #21847). Layer 6 of 6. The Mac handoff note for the whole stack is in the comments below.

Testing:

  • Settings logic: adding, editing and removing an EAS host, limit validation, and the summary line.
  • Device setup: a test covers the EAS wording.
  • In the app, against a real Expo account: adding a host, the check on open, the project picker, a stored token shown redacted and cleared, a rejected token's message, and the labelled token field.
  • Web, client-runtime, server and contracts typechecks pass.

Done with Claude Opus 5.5 in Claude Code, running in T3 Code.

Screenshots

Dev build at the stack top, Settings → Integrations, 1280×800. Before this stack the Integrations page had no EAS section at all (the server did not know EAS hosts), so there is no "before" state to show beyond its absence.

EAS Simulator section with one host configured (limits in one line; the note that editing or removing stops running sessions):

EAS Simulator section in Settings → Integrations with one host, its limits, and Edit/Remove

Editor for a saved host: the account check ran on open (signed in through the server's eas login), the saved project shows by name, limits, and the restart note:

Edit EAS host dialog showing the account check result, project picker, and session limits

Invalid limits: idle minutes set equal to session minutes disables Save and says why:

Edit EAS host dialog with idle minutes equal to session minutes, Save disabled, and the reason shown in red

Handoff: verifying the EAS Simulator stack on a Mac

This comment covers the whole stack (#21835 → #21841 → #21842 → #21843 → #21844 → #21846). It was built and tested on Linux, where no iOS Simulator can run, so what needs a Mac and a real browser is listed here.

Already verified (Linux)

  • Typechecks: server, web, client-runtime, contracts and mobile pass.
  • Tests: after rebasing onto 729924a, the touched suites pass: 182 server device/MCP/settings, 146 client-runtime device, 4 contracts and 17 web.
  • Live check against Expo, one real session through EasDeviceHost (#21844):
    • ready in 51 s;
    • /api routed with the session token reports transport: webrtc;
    • AVCC answers 409 stream_transport_locked;
    • the WebRTC offer route answers;
    • the input socket admits input (0x83);
    • a 2.9 MB PNG screenshot came back;
    • the agent daemon's /health answered 200;
    • the session was stopped when the host closed.
  • Not watched yet: the WebRTC video itself, anything in a real browser, and the settings UI.

Setup

sh
1gh stack checkout 21846 # or: git fetch origin device/eas-settings && check it out in a worktree
2vp i
3vp run migrate-dev-db # optional: real data in the worktree's .t3
4vp run dev # read the real ports from the [dev-runner] line

Expo credential on the Mac, one of:

  • eas login (or npx expo login);
  • EXPO_TOKEN in the dev server's environment;
  • a token pasted into the EAS host in Settings.

The account must have EAS Simulator enabled; pingdotgg does.

1. Local simulators still work (#21835, #21841)

  • Device panel → open a local iOS Simulator. The video streams over AVCC as before, touch and keyboard work, and rotate, Home, screenshot and shutdown all work.
  • Same with an Android emulator if you have one.
  • iOS in a browser without WebCodecs, or the mobile app: still falls back to MJPEG.

Expect no changes from main here; the WebRTC path only starts when serve-sim refuses AVCC with a 409.

2. Add an EAS host (#21842, #21843, #21846)

  • Settings → Integrations → EAS Simulator → Add EAS host.
  • Check account shows "Signed in as … with the server's eas login" (or EXPO_TOKEN, or the saved token), and the project picker lists the account's apps.
  • Choose @pingdotgg/t3-code, or keep "From the thread's project". Set 1 session at once, 10 session minutes and 5 idle minutes. Save.
  • Reload Settings: the token shows as stored, never in plain text, and Check account still works with the saved token.
  • Screenshot the row and the editor for the PR.

3. Open an EAS device (#21844, with the WebRTC path from #21841)

  • The Device panel lists iPhone (EAS Simulator). Opening it shows booting for about a minute, then the simulator appears with live video.
  • chrome://webrtc-internals shows an inbound H.264 video track. Touch input, rotate and Home work. The screenshot button returns an image.
  • Try Safari. The video element is hidden but in the DOM, because Safari may not deliver requestVideoFrameCallback frames for detached video.
  • Try the mobile app. Its WebView starts on MJPEG, gets refused, and should switch the canvas back on (onCanvasVideo).
  • Opening a second device with the limit at 1 is refused with "… is limited to 1 running session".
  • Shut the device down. On expo.dev → pingdotgg → t3-code → simulator sessions, the session (named T3 Code · <label> · <id>) is stopped.
  • Record a short video of the stream for the PR.

4. Agent access (#21844)

  • With device agent access on, ask an agent in a thread: "open the EAS iPhone, open Settings and take a screenshot, then close it". device_open's quick start mentions EAS and billing, agent-device works through the returned --config/--session, and device_close with shutdown: true stops the session.
  • A thread whose project has an Expo app config, with the host left on "From the thread's project", runs the session under that project.

5. Cost guards (#21844)

  • Open an EAS device, kill the dev server by the PID you started it with, and start it again. When the device hub comes up, the leftover session is stopped (check expo.dev).
  • Let a session idle past its idle minutes. It drops out of the device list on the next refresh, and a new one can start.
  • Turn device support off while a session runs. The session stops.

Known gaps and decisions for review

  • iOS only. Android on EAS reports unsupported. Device settings (appearance, permissions and so on) are unavailable on EAS devices because they run simctl on the simulator's machine. There is no egress tunnel yet, so a simulator cannot reach Metro on this machine; agents install builds with agent-device install-from-source <url> instead.
  • Closing a panel without shutting down keeps the session running until its idle limit, 10 minutes by default.
  • Expo API: the GraphQL operations are the hidden ones eas-cli's simulator:* commands use. They are decoded by hand because Expo publishes no schema for them.
  • Slower failure for local MJPEG viewers: in browsers that have WebRTC, a failing MJPEG image now probes /api (up to 5 s) before reporting the error.

MmacroscopeappBoton line 110820d ago

This maps every credential-resolution and Expo API failure into reason: cause.message, which exposes arbitrary lower-level error text through the RPC and drops the underlying cause. Could you preserve known safe credential errors as structured cases, normalize unknown failures to a bounded category/message, and retain the immediate error as cause on the server-side error (without serializing it to the browser)? This needs coordinated changes to the RPC error schema and mapping, so there is no self-contained suggestion.

Posted via Macroscope — Effect Service Conventions

JJulius Marminge20d ago

DeviceEasAccountError carries only reason on purpose: it reaches the browser, and the credential-resolution and Expo errors it maps hold a cause with the request's credential header. reason is the message those errors compose themselves: a sign-in hint naming the credential's source, or "Expo could not : <Expo's reason>"; the token value never enters a message (asserted in ExpoApi.test.ts). The structured cases the comment asks for already exist one layer down (ExpoNotSignedInError, ExpoInvalidCredentialError, ExpoApiError with operation/rejected); this RPC flattens them to text for the editor's one-line account check.

MmacroscopeappBot20d ago

The lower-layer cases exist, but ExpoApiError composes Expo GraphQL error messages verbatim, and the RPC forwards that text to the browser via cause.message. It also discards the immediate cause rather than retaining it server-side. So the concern remains.

JJulius Marminge20d ago

Same scrub applies to what reaches reason here (789011b1cf3 in #21843): Expo's message without the credential, bounded. The cause is still not kept on this error on purpose, since the error is serialized to the browser and the cause would hold the request with its credential header; the server logs the underlying failure where it occurs.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — This XL PR introduces EAS Simulator host configuration, Expo credential handling, a new authorized RPC, and billable cloud-session behavior across the web, server, and contracts layers. The new auth and sensitive-token paths, product defaults, and lifecycle side effects require human review.

📝 Walkthrough

The change adds an EAS account lookup RPC, EAS device-host settings, EAS host capability reporting, and EAS Simulator guidance for ready EAS hosts.

Changes: EAS device host support

Layer / File(s)Summary
EAS account lookup and RPC wiring
packages/contracts/src/device.ts, packages/contracts/src/rpc.ts, packages/client-runtime/src/state/device.ts, apps/server/src/device/DeviceService.ts, apps/server/src/ws.ts, apps/server/src/auth/RpcAuthorization.ts, apps/server/src/observability/RpcInstrumentation.ts		The contracts define EAS account inputs, results, errors, and the supportsEasHosts capability. The client adds the RPC command. The server resolves credentials, queries Expo account details, maps failures to DeviceEasAccountError, and exposes the authorized WebSocket RPC.
EAS host settings and editing
apps/web/src/components/settings/easDeviceHostsSettings.logic.ts, apps/web/src/components/settings/easDeviceHostsSettings.logic.test.ts, apps/web/src/components/settings/EasDeviceHostsSettings.tsx, apps/web/src/components/settings/IntegrationsSettings.tsx		Settings can add, edit, remove, and save EAS hosts. The editor checks credentials, rejects invalid labels and session limits, displays Expo projects, and disables controls based on authorization, scope, environment, and operation state.
EAS Simulator setup guidance
apps/web/src/components/device/DeviceSetup.tsx, apps/web/src/components/device/DeviceSetup.test.ts		Ready iOS setup status identifies EAS Simulator for an EAS host. A test covers this status when local tooling is unavailable.

Editing an EAS host's token field and then emptying it quietly removes the saved Expo token when the host is saved. Saving also restarts the host, so the server may then sign in with a different account. Ordinary edits keep the stored token. This is a small, easy fix to make before or soon after merge.

Map EAS account failures to bounded reasons.

ExpoNotSignedInError and ExpoInvalidCredentialError expose fixed messages. ExpoApiError.message includes API-derived detail, so do not forward it. The detail is truncated and credential-scrubbed, but it is still arbitrary remote text.

✅ Confirmed as addressed by @juliusmarminge

JJulius Marminge20d ago

Done in 464421da08f: the reason is now the credential errors' own guidance, or a category for what Expo answered — "Expo rejected the credential (HTTP 401/403)." from the status ExpoApiError now carries, "Expo refused the account check." for a refusal, "Could not complete the Expo account check." otherwise. Expo's text is not forwarded.

CcoderabbitaiBot20d ago

@juliusmarminge Thanks. The supplied code maps ExpoApiError to bounded messages and no longer forwards Expo’s response text. This addresses the finding.

Preserve the cleared-token state during account checks.

When an existing host token is cleared, requestCheck omits accessToken. DeviceService.easAccount then uses the saved token through input.accessToken || saved. The check can show the old account and projects, although Save clears the token and the host then uses EXPO_TOKEN or eas login.

Send an explicit empty token for the cleared state, and use nullish fallback on the server.

JJulius Marminge20d ago

Done in 464421da08f: a cleared token is sent as accessToken: "" and the server uses ??, so the check runs with the environment's credential, which is what the host will use once Save drops the stored token.

CcoderabbitaiBot20d ago

@juliusmarminge Thanks for fixing this. Sending accessToken: "" and using ?? preserves the cleared-token state, so the account check uses the same credential source as the host after Save.

Restore the saved token when the user empties the field.

If the host already has a saved token, the token state starts as { kind: "saved" }. The first keystroke changes it to { kind: "new" }. If the user then deletes all text, onChange sets the state to { kind: "cleared" }. The saved state never comes back. After that, next.accessToken is "". Save drops the stored token and restarts the host, which stops its running sessions. The server then signs in with EXPO_TOKEN or eas login, and that credential can be a different Expo account. SecretInput has a guard against this in its onCommit path (configured && next === ""). This editor uses onChange, so that guard never runs. The explicit Clear access token button already handles intentional clearing. An empty field should therefore return to the saved state.

Done in 340ad3ea50a. Emptying the field returns to saved when a token is stored; only the Clear button yields cleared.

CcoderabbitaiBot20d ago

@juliusmarminge Thanks for the fix. Restoring saved when the field is emptied addresses this finding.
