…al VM Allow POST /api/bots/:id/local-computer/screenshot through the sidecar, behind the same per-device computer-access capability as the cloud desktop (off by default, toggled in Settings → Remote access). Only the still is reachable: the VM's lifecycle routes stay host-only. The 403 now says "computer access" since it covers both kinds of computer.
ComputerView now asks for a Local VM still every 30 s while it is on screen (every 3 s while the bot works and the stream has gone quiet), the desktop panel's cadence, and shows whichever of that and the streamed frame is newer. A 403 explains where to allow computer access on the Mac; a 409 for a conversation not on the Local VM, or a 404 from an older computer, leaves the existing behaviour alone. Polling stops in the background. Adds the client call, a strict data-URL decoder, tests, and pt-BR strings.
A disposable fake-engine server, a synthetic docker that serves PNG stills, and the companion sidecar, so the phone's Local VM view and its computer-access gate can be checked from a simulator without a real VM.
…ges live - Project the bot onto the thread the view was opened from, so a task thread pictures its own computer (and its own seat in pool mode). - Keep checking at the idle cadence while computer access is off, so turning it on at the Mac shows up without leaving the view; revoking it clears the picture. Only the sidecar's "computer access is off" 403 is read as that. - Stamp a still when it was requested, and label the last picture when a refresh fails instead of letting it pass for current. - Move CloudDesktopSession's doc comment back onto it; say in the docs that the thread check is the client's and that polling keeps the VM from being reclaimed as idle, like the desktop panel.

Suggested reviewers: Merge Risk: ⚪ Minimal · up to The computer view can retain a streamed image while showing the access-off notice. No supported merge-blocking risk remains. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to Screenshot access remains explicitly enabled per phone, and this addition does not grant VM lifecycle controls. The main concern is preview ownership: an idle conversation without a current pool assignment can resolve to the default VM seat rather than its own desktop. No authorization bypass was established.

Review comments at @ios/App/ComputerView.swift:
- Around line 54-56: Update the shownImageData getter to return nil when
vmProblem is .accessOff before selecting either the polled screenshot or
streamed frame, so the access-off notice can render.
- Around line 55-56: Carry threadId into the streamed-frame model and update the
ComputerView frame selection around polled and streamFrameAt to ignore frames
whose threadId does not match bot.threadId, preserving the existing selection
behavior for matching frames.
Review comments at @ios/App/Session.swift:
- Line 1660: In the unauthorized-error handler that sets status to
`.unauthorized`, first check that the task is not cancelled and the active
client’s connection ID still matches the captured client’s ID; throw
`CancellationError` if either check fails, then preserve the existing status
update and error propagation.
Review comments at @scripts/verify-ios-local-vm.ts:
- Line 146: Update the `launchVerificationServer` startup flow to accept an
`AbortSignal` and cancel startup when SIGTERM arrives. In the signal handler,
abort and await startup cleanup before calling `process.exit()`; if startup has
completed, close the returned `fixture` instead. Ensure this also removes the
launcher's temporary data directory.

…e a stale 401 With access off, a streamed frame of a working bot could stay on screen and hide the access notice. The frame stays (the stream is not gated), captioned with the notice. A screenshot 401 from the previous computer, landing after a switch, no longer marks the new session unauthorized.
A signal during startup now aborts the launch, which stops the server child and removes its data directory, instead of leaving both behind.

What changed
The phone's computer view can now show a bot's Local VM on demand, including while the bot is idle. Until now it only showed frames the harness pushes during a turn, so an idle Local VM bot always read "Nothing to show yet", while the desktop panel shows the VM at any time.
companion/src/routes.ts,proxy.ts): allowsPOST /api/bots/:id/local-computer/screenshotbehind the existing per-device computer-access capability (cloudDesktopAccess, shown on the Mac as Allow computer view, off by default). The VM's lifecycle routes (GET /api/bots/:id/local-computer,run,stop,remove) and the shared/api/local-computer/*routes stay host-only. Because the 403 now covers both kinds of computer, it reads "computer access is off for this device".ComputerView.swift,Client.swift,Models.swift,Session.swift): while the computer view is open and the app is active, the phone asks for a still every 30 s, or every 3 s while the bot works and its streamed frames have gone quiet. That's the desktop panel's cadence. It shows whichever is newer, the still or a streamed frame. It always passes the conversation'sthreadId, so a task thread pictures its own Local VM, or its own seat in pool mode.ios/README.md,docs/ios-companion.md,companion/README.md, and a new verification recipe,docs/verification/ios-local-vm.md, with its fixturescripts/verify-ios-local-vm.ts.Why it's safe to expose
docs/ios-companion.mdlists Local VM interaction as needing its own threat-model review, so here's the reasoning:data:image, plus 409 problem strings such as "The Local VM is not ready". It can't start, stop, remove, or drive the VM, and no viewer URL, password, or port reaches the phone.[\w-]+excludes.,%, and/. OnlyPOSTis allowed, andGETis refused (tested).
