What changed

  • adds a per-paired-device Cloud desktop permission in desktop Companion settings, off by default
  • exposes only the existing fresh cloud viewer join route through the companion sidecar
  • opens the provider's HTTPS noVNC viewer in a hardened in-app Safari session after an explicit full-control warning
  • keeps Local VM, host-computer access, provisioning, sleep, shell, screenshots, provider keys, and viewer URLs outside the mobile surface
  • documents the security boundary and App Store review flow

Why

The iOS companion already shows computer previews, but cloud-backed bots need a deliberate way to enter the live interactive desktop. A fresh provider viewer URL lets the existing noVNC stack do that without embedding VNC credentials or adding OpenMausBot account authentication.

The paired-device bearer token remains the phone-to-Mac identity. Full cloud desktop control is a separate capability the computer owner must enable for each phone.

Validation

  • pnpm typecheck
  • pnpm test — 986 passed, 8 skipped
  • pnpm check:electron
  • pnpm build
  • swift test — 88 passed
  • unsigned generic iOS Simulator build — succeeded

Summary by CodeRabbit

  • New Features
    • Added optional per-device cloud desktop access, disabled by default.
    • Added controls to enable or disable access for paired devices.
    • iOS users can open a fresh interactive cloud desktop viewer in-app.
    • Added high-entropy QR credentials alongside the six-digit pairing fallback.
  • Security
    • Sessions require explicit device authorization and secure HTTPS URLs.
    • Local computer and Local VM controls remain unavailable.
    • Viewer links and provider credentials are not stored.
  • Documentation
    • Updated setup, permissions, pairing, and review guidance.

📝 Walkthrough

Walkthrough

This change adds per-device cloud desktop authorization. The companion persists and enforces the setting, desktop controls expose it, and the iOS app requests and presents fresh HTTPS viewer sessions without storing provider credentials.

Changes

Cloud desktop capability control

Layer / File(s) Summary
Per-device state and control surfaces
companion/src/devices.ts, companion/src/control.ts, electron/..., src/components/CompanionSection.tsx, companion/test/control.test.ts, companion/test/devices.test.ts
Device records default cloud desktop access to disabled, persist changes, and expose enable or disable controls through the companion and desktop UI.
Authorization and route enforcement
companion/src/index.ts, companion/src/proxy.ts, companion/src/routes.ts, companion/README.md, companion/test/proxy-response.test.ts, companion/test/proxy.test.ts, companion/test/routes.test.ts, companion/test/upstream-failure.test.ts
Authentication preserves device metadata. The viewer join route is allowlisted, then restricted to devices with cloud desktop access enabled.
iOS session contract
ios/Sources/CompanionCore/*, ios/App/Session.swift, ios/README.md, docs/ios-companion.md, ios/Tests/CompanionCoreTests/ConnectionTests.swift
The iOS client requests a fresh viewer session and accepts only HTTPS URLs with hosts. Documentation defines the remaining refused capabilities.
iOS viewer flow
ios/App/ComputerView.swift, ios/App/CloudDesktopBrowser.swift, ios/AppStore/review-notes.md
The computer view confirms access, requests the session, reports errors, and presents the returned URL in an in-app Safari view.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: ⚪ Minimal · up to 1b8fa

This change adds an explicitly opt-in cloud desktop access path with the capability off by default, and no actionable merge-blocking risk remains based on the supplied checks and review state.

- Around line 179-185: Update the cloud-desktop route around
setCloudDesktopAccess to catch persistence exceptions, ensure the registry
restores its previous value, and return an appropriate 5xx JSON response instead
of allowing the error to escape the HTTP callback. Preserve the existing 404
response for unknown devices and 200 response for successful updates.

In `@companion/src/routes.ts`:
- Around line 64-66: Define and export a single cloud desktop join classifier in
companion/src/routes.ts at lines 64-66, replacing the inline route regex while
preserving its matching behavior. Update companion/src/proxy.ts at lines 150-154
so the cloudDesktopAccess check reuses that exported classifier instead of
maintaining a separate regular expression.
