Summary

  • adds a Local VM workspace with exactly two live watch-only panes and one active controller
  • hardens both WebContentsView sessions to loopback-only navigation, transient isolation, denied permissions, blocked popups, and a two-view ceiling
  • serializes control handoff with lease ownership so the old pane is demoted and released before the next pane becomes interactive
  • validates and injects a 300-second freshness-bound OpenMaus status capsule only for the configured Chief
  • binds the Hermes screenshot compatibility opt-in to the exact selected injected model

Security and behavior

Opening the workspace never provisions or starts a VM. Missing or stopped VMs route back to their Computer panel. Viewer URLs and credentials never enter workspace state or state events. Stale, failed, clock-skewed, malformed, insecure, or hash-mismatched status data projects runtime as unknown with ready_count=0.

The existing single viewer remains for cloud/shared/single-view flows.

Verification

  • Node 24.19.0 / pnpm 10.33.0
  • focused Chief, status, Hermes binding, control API, workspace reducer, and viewer tests: 51 passed
  • Electron viewer/workspace tests: 13 passed
  • post-race status/workspace selectors: 22 passed
  • TypeScript typecheck, production build, Electron check, and packaged-server smoke passed
  • full suite was not repeated under host load; the earlier full attempt had 1523 pass, 12 skip, and 12 unrelated child-server startup timeouts under contention
  • cached diff and redacted gitleaks scan passed

Closes #353
Related: #332, #322, #187

📝 Walkthrough

Walkthrough

The change adds a two-pane Local VM desktop workspace with isolated Electron viewers, lease-aware control switching, secure viewer handling, and renderer integration. It also adds signed OpenMaus status capsules, conditional prompt injection, Hermes compatibility binding, and validation tests.

Changes

Local VM desktop workspace

Layer / File(s) Summary
Native workspace lifecycle and security
electron/desktop-workspace.cjs, electron/desktop-workspace.node-test.mjs, package.json
The manager validates viewer inputs, bounds, contexts, capacity, and duplicate identities. It creates isolated sandboxed views, restricts navigation and permissions, serializes interaction changes, reports failures, and supports layout and closure operations.
Electron ownership and bridge wiring
electron/main.mjs, electron/preload.cjs, src/types/ogb.d.ts
The main process owns workspace views for the application window. IPC handlers and typed preload methods expose opening, layout, interaction, closure, and state updates.
Workspace control and status helpers
src/lib/local-vm-workspace.ts, src/lib/local-vm-workspace.test.ts
Helpers select and reconcile two eligible bots, sanitize VM status, detect obscuring overlays, and coordinate lease-aware control transitions.
Two-pane workspace UI
src/components/LocalVmWorkspace.tsx, src/components/ComputerPanel.tsx, src/components/CommandPalette.tsx, src/App.tsx, apps/docs/content/docs/computers/local-vm.mdx
The UI renders two native viewers, manages selection and cleanup, updates visibility during overlays and resizing, adds entry points from the computer panel, and documents dual-desktop setup and interaction rules.

OpenMaus status capsule

Layer / File(s) Summary
Signed status validation and prompt data
server/openmaus-status-capsule.ts, server/openmaus-status-capsule.test.ts
The server validates signed capsule schemas, hashes, timestamps, VM state, UI consistency, and secure cache-file access. It returns normalized fresh or unknown status data and formats prompt metadata.
Trusted status prompt integration
server/index.ts, server/chief-of-staff.ts, server/chief-of-staff.test.ts
Chief of Staff prompts can include the validated OpenMaus status block. Ordinary caller prompts do not receive it.

Computer-control leases

Layer / File(s) Summary
Atomic lease ownership
server/computer-control.ts, server/computer-control.test.ts
Control holds now track internal lease identifiers. Acquisition is atomic, competing ownership is preserved, and release requires the matching lease.
Lease-aware API handling
server/index.ts, server/index.test.ts
The API validates optional lease IDs and returns ownership and acquisition or release results without exposing lease identifiers. Requests without leases retain legacy behavior.

Hermes screenshot compatibility

Layer / File(s) Summary
Model-specific compatibility binding
server/drivers/acp/hermes.ts, server/drivers/acp/hermes.test.ts
Model resolution clears stale screenshot compatibility settings and binds compatibility to the decoded injected model when available.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟡 Moderate · up to 6f06f

This PR adds a two-pane Local VM workspace with exclusive control handoff and Chief status processing, but unresolved issues could block the server during Chief turns, activate the wrong pane during concurrent UI updates, or leave a removed pane holding control. The PR requires owner follow-up or explicit acceptance before merge.

302-341: 🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick win

Consider memoizing the capsule read to keep synchronous I/O off the turn path.

readOpenMausStatus runs lstat twice, open, fstat, readFileSync, JSON parsing, Zod parsing, recursive canonicalization, and a SHA-256 hash on every call. openMausStatusSystemPrompt is invoked on the runtime turn path at server/index.ts:1613, so this synchronous work blocks the event loop for each Chief request.

The freshness decision already derives from options.now, so the parsed capsule can be cached safely. Cache the validated capsule keyed by the resolved path and invalidate it on dev/ino/mtimeMs/size change, or use a short time window. Keep the freshness and skew checks outside the cache.

Add coverage for the ready-slot safety rule and the slot-order rule.

The filesystem-security cases look complete. Two validation rules in validateCapsule remain untested:

  • validSlotState rejects a slot with readiness: "ready" unless container is running, network is loopback, security is hardened, and persistence is durable.
  • The slot index rule requires slots[i].slot === "vm-" + (i + 1).

Both rules block a signed capsule from advertising an unsafe or misordered ready pane. Add one case per rule that signs the capsule and expects reason to be "invalid".

Assert the HTTP status for the denied acquisition and the mismatched release.

The test checks only the response bodies. The renderer helper throws on any non-OK response (src/components/ComputerPanel.tsx Lines 42-47), and src/components/LocalVmWorkspace.tsx Lines 59-62 posts the same endpoint. If the status for a denied lease later changes from 200 to 409, the renderer stops reading owned: false and throws instead. This test would still pass.

Add status assertions so the contract is pinned.

51-66: 🔒 Security & Privacy | 🔵 Trivial | ⚡ Quick win

Add a case that a null lease cannot release a manual hold.

take stores controlLeaseId: null (server/computer-control.ts Lines 80-90). releaseLease compares entry.controlLeaseId !== controlLeaseId (Lines 122-129). A caller that reaches releaseLease with null therefore matches a hold created by take and releases the user's control. The API layer rejects malformed leases today, so this is a latent invariant rather than a live defect.

Add an assertion that pins the invariant.

💚 Proposed additional assertion
     expect(control.releaseLease("b1", leaseId)).toMatchObject({
       released: false,
       snapshot: { held: true },

Do not tear down the viewer when only the bot name changes.

botName is in the dependency array. It is used only for the native window title. A rename while the workspace is open closes the WebContentsView and reopens it, which drops the live noVNC session and restarts the connection.

Hold the name in a ref and read it inside run.

Move the slotsRef write out of render.

Line 499 writes slotsRef.current during render. React can discard or replay a render, so slotsRef can hold a slots value that never commits. contextForBot reads this ref during takeControl and maps a bot to a pane context, so a discarded value can promote the wrong pane.

Line 503-504 is different. That is the null-guarded lazy initialization pattern, which stays valid.

♻️ Proposed change
   const slotsRef = useRef(slots);
-  slotsRef.current = slots;
+  useEffect(() => {
+    slotsRef.current = slots;

contextForBot already has an empty dependency array, so it keeps reading the committed value.

Release the API hold even when native demotion fails.

releaseLocalVmWorkspaceControl awaits port.setInteractive(null) before port.release(currentBotId). If the bridge is unavailable, setInteractive rejects and the hold is never released. The bot then stays held while the pane is already gone.

switchLocalVmWorkspaceControl already treats a failed demotion as fail-closed and still releases. Apply the same order here.

♻️ Proposed change
 export async function releaseLocalVmWorkspaceControl(
   port: LocalVmWorkspaceControlPort,
   currentBotId: string | null,
 ) {
   if (!currentBotId) return null;
-  await port.setInteractive(null);
-  const released = await port.release(currentBotId);
-  return released;
+  try {
+    await port.setInteractive(null);
+  } finally {
+    // The native manager removes a view it cannot demote, so releasing the
+    // API hold afterwards stays fail-closed.
+  }
+  return port.release(currentBotId);
 }

A try/finally alone still rethrows. If you want the release to always run, wrap the demotion in await port.setInteractive(null).catch(() => {}) and surface the demotion failure separately.

Owner-fork closeout completed: the exact verified head 10efdb9 was squash-merged through lightcloud00#1 at fork merge commit 83922de. Upstream PR #365 remains the canonical maintainer-controlled acceptance lane. Its required macOS, Ubuntu, and Windows checks are green; Vercel authorization is a separate external status.

Closeout update for exact head a6855b7:

  • Merged current upstream main without rebasing.
  • Fixed all five actionable review threads: URL derivation now fails closed, open no longer reports phantom-ready panes, interactive changes use the live pane map, capsule cleanup errors are contained, and the workspace button requires the ready VM phase.
  • Included the low-risk hardening nits for Electron webPreferences, committed-slot mapping, and API lease release after native demotion failure.
  • Added focused regressions for invalid reload URLs, close-during-open, reverse-order queued switches, and demotion-failure lease release.

Fresh local verification:

  • Electron workspace: 11 passed
  • affected Vitest suites: 127 passed, 1 skipped
  • typecheck: passed
  • production build: passed
  • Electron syntax check: 33 modules
  • packaged-server smoke: passed, including all 8 proxy paths
  • git diff check and gitleaks commit-range scan: passed

The remaining review nits are non-blocking follow-up candidates: capsule-read memoization needs a measured performance case; bot-name-only viewer lifecycle optimization is UX/performance scope; and the suggested extra ready-slot/order, Chief integration, HTTP-status, and null-lease assertions add coverage without identifying a current failing contract. No installation, VM restoration, deployment, or live canary was performed. Fresh platform CI is running; Vercel authorization remains external to application code.

97-111: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Centralize the workspace types.

src/components/LocalVmWorkspace.tsx redeclares DesktopWorkspaceBounds and DesktopWorkspaceState at Line 97 through Line 110. Move these definitions to a shared module and reference them from both the global bridge declaration and the renderer. Otherwise, future changes can leave the two contracts independently type-correct but inconsistent.

Drop botName from the open-effect dependencies.

botName is used only for the native view title (Line 305). Including it in the dependency list makes a bot rename tear down and recreate the viewer, which drops the live desktop session for that pane. Read the name from a ref, or update the title through a separate effect.

- Around line 296-301: Bound the animation-frame wait in the live-view setup
flow around safeStatus, viewerUrl, and viewportRef so it always settles when the
document is hidden or minimized. Race requestAnimationFrame with a short
timeout, then continue to the existing alive check and elementBounds read
without changing the cleanup behavior for operationRef.
