perf: faster, lighter desktop startup and streaming - #28991
A fresh desktop launch waits about 1.6 s before showing a window. It then writes 40 MiB and 418 files to the home directory, and keeps several services and timers busy that an idle app never uses.
The main window now opens from a small bootstrap entry before the runtime and backend load. Idle work moves behind first use: the resource monitor, MCP OAuth keys, secret salts, native passkeys, the editor inventory, provider discovery and SQLite readers. New databases use smaller pages and checkpoint after migrations. Untouched providers write no status file. Linux and macOS share Chromium's network-service and code-cache settings. The packaged app ships a main-process compile cache, stripped native modules and fewer assets. Backend bytecode comes from main's prepared server cache (#32987, #33050). Live streaming moves to an imperative markdown renderer that stays outside React updates, and closed panels such as the command palette load on demand. An idle terminal cursor stops blinking after two blinks and resumes on output or focus. The local resource monitor samples only while something reads it, unless OTLP metric export is configured.
Measured with the packaged Linux AppImage at main fa31b66bbb and this PR b637c43b86. Each launch used a fresh home and a 60 s idle period. The table shows medians of 6 alternating paired rounds on one 4 vCPU / 8 GB VM. Deltas are per-round medians. Spread is min to max, not a confidence interval. This PR then prepared Linux backend bytecode itself, which main now does, so the table overstates its gain against current main.

vp run check:changed passes: 101 test files, 2,169 tests. The benchmark boots the production AppImage. macOS packaging (afterPack signing and the main-process cache) and streaming render cost were not benchmarked against main here.
Maintainer sign-off needed: apps/desktop/vite.config.ts adds the bootstrap entry (bundling). packages/contracts gains two optional fields: DesktopBridge.onLocalEnvironmentBootstrapsChanged and ServerConfig.availableEditorsPending.

Changes: Desktop startup and runtime
Layer / File(s)
Summary
Early desktop boot and pre-ready setup apps/desktop/src/boot.ts, apps/desktop/src/initialWindow.ts, apps/desktop/src/app/configureBeforeReady.ts, apps/desktop/src/app/DesktopPreReadyPlatform.ts, apps/desktop/src/app/desktopBootState.ts, apps/desktop/src/window/mainWindowOptions.ts, apps/desktop/src/window/DesktopWindow.ts, apps/desktop/src/app/DesktopApp.ts, apps/desktop/src/app/DesktopApp.test.ts, apps/desktop/scripts/main-process-bundle.test.mjs, apps/desktop/src/window/DesktopWindow.test.ts, apps/desktop/src/app/DesktopPreReadyPlatform.test.ts
Desktop startup can open an initial window before main.cjs continues. Pre-ready setup moved into configureBeforeReady. Boot state stores pre-ready options, queued link events, and an optional window for reuse during full startup.
DesktopClerk now exposes deferred protocol registration, replays queued boot links, and uses lazy Clerk storage. Backend-pool changes and resume events now publish a desktop bootstrap-change notification through IPC and the desktop bridge.
Desktop runtime now supports packaged compile-cache activation, compressed protocol assets, synchronous scheme privilege registration, shared early-settings parsing, extracted Linux desktop-entry helpers, and dynamic updater or preview imports in several paths.
Server runtime and provider lifecycle
Layer / File(s)
Summary
Provider discovery and lazy runtime loading apps/server/src/provider/ProviderRegistry.ts, packages/provider-core/src/server/managedProvider.ts, packages/provider-core/src/server/snapshot.ts, apps/server/src/textGeneration/*, apps/server/src/provider/Drivers/*, apps/server/src/provider/*, apps/server/src/git/GitManager.ts, apps/server/src/mcp/toolkits/project/handlers.ts, apps/server/src/orchestration-v2/*, apps/server/src/pullRequest/PullRequestReviewGuideService.ts, related tests
Provider discovery now uses discoverProviders in multiple call sites. Managed providers add optional ensureReady. Several provider and text-generation paths now lazy-load modules and wait for readiness before adapter or snapshot use.
Server scheduling, telemetry, and process retention apps/server/src/scheduling/*, apps/server/src/scheduledTasks/*, apps/server/src/resourceTelemetry/*, apps/server/src/terminal/Manager.ts, apps/server/src/preview/PortScanner.ts, packages/shared/src/nodeSqliteClient.ts, related tests
The scheduler now accepts an optional awaitNext effect. Due hints can wake waiters directly. Native telemetry uses reference-counted monitor retention and retained history. Terminal and scanner polling now react to active demand instead of fixed loops.
Server HTTP, MCP, persistence, and maintenance updates apps/server/src/http.ts, apps/server/src/lazyHttpRoutes.ts, apps/server/src/server.ts, apps/server/src/auth/McpOAuth.ts, apps/server/src/mcp/*, apps/server/src/ws.ts, apps/server/src/persistence/Sqlite.ts, apps/server/src/background/BackgroundPolicy.ts, apps/server/src/secrets/SecretRequests.ts, packages/provider-core/src/server/maintenanceResolver.ts, related tests
The server can serve .br and .gz static assets, lazy-load /mcp routes, defer initial editor discovery while marking it pending, update fresh SQLite initialization steps, remove one background lease cleanup loop, and switch npm version lookup to npm dist-tag ls.
Web rendering and bootstrap
Layer / File(s)
Summary
Bootstrap and desktop-aware connection flow apps/web/src/bootstrap.ts, apps/web/src/main.tsx, apps/web/src/connection/desktopLocal.ts, apps/web/src/connection/platform.ts, apps/web/src/connection/useDesktopLocalBootstraps.ts, apps/web/src/routes/__root.tsx, apps/web/src/components/desktop/DesktopCoordinators.tsx, related tests
Web startup now waits for desktop bearer-token retrieval before calling startup() when desktop local access is enabled. Platform reconciliation now wakes from topology-change events and computed deadlines instead of a fixed poll.
Streaming markdown and timeline behavior apps/web/src/components/chat/ImperativeLiveMarkdown.tsx, apps/web/src/components/ChatMarkdown.tsx, apps/web/src/components/chat/TimelineAssistantRows.tsx, apps/web/src/components/chat/MessagesTimeline.tsx, apps/web/src/components/chat/timelineViewport.ts, apps/web/src/components/chat/useTimelineFollow.ts, apps/web/src/components/chat/MarkdownExternalLink.tsx, apps/web/src/components/chat/markdownStreamBlocks.ts, related tests
The web app adds ImperativeLiveMarkdown for append-only streaming assistant text. Timeline state marks one imperative live row, and viewport or follow logic uses that row for position tracking and scrolling behavior.
Lazy-loaded dialogs, panels, and UI state updates apps/web/src/components/CommandPalette*.tsx, apps/web/src/components/chat/panelModules.ts, apps/web/src/components/chat/RightPanelSurfaceContent.tsx, apps/web/src/components/chat/ChatTerminalDrawers.tsx, apps/web/src/components/CustomSnoozeDialog*.tsx, apps/web/src/components/ConfirmDialogHost.tsx, apps/web/src/components/cloud/RelayClientInstallDialog.tsx, apps/web/src/components/chat/OpenInPicker.tsx, apps/web/src/components/ui/button.tsx, apps/web/src/index.css, apps/web/src/terminal/ghostty/surface.ts, related tests
The command palette moved into a lazily loaded dialog module. Several right-panel and desktop-only components now load through dynamic imports. UI hosts now return null for idle states in some dialogs, and multiple animation or focus behaviors changed.
Shared state and packaging
Layer / File(s)
Summary
Shared client-state and contracts packages/client-runtime/src/state/*, packages/contracts/src/server.ts, apps/web/src/state/entities.ts, apps/web/src/state/v2ItemSupport.ts
Client runtime state adds lazy schema equivalence helpers, a structure-focused thread projection, and assistant-text subscriptions that suppress streamed-text-only structure updates. ServerConfig adds optional availableEditorsPending.
Desktop packaging and post-pack hooks scripts/build-desktop-artifact.ts, scripts/lib/desktop-compile-cache.ts, scripts/desktop-after-pack.ts, patches/[email protected], patches/@[email protected], apps/desktop/vite.config.ts, pnpm-workspace.yaml, knip.jsonc, related tests
Desktop packaging now prebuilds portable compile caches, minifies selected runtime JavaScript, precompresses client assets, deduplicates repeated Chromium license blocks, patches Clerk protocol registration flags, and routes shared after-pack work through desktop-after-pack.ts.
The change makes desktop startup and streaming faster and lighter. Remaining issues are narrow failure paths: terminal startup when node-pty cannot load, provider discovery under a slow or failing provider, and a palette chunk that fails to load after reload. Each is worth fixing, but none is likely to affect normal use.

Avoid re-serializing the full retained history on every readHistory request.
retainHistory calls JSON.stringify on every snapshot to compute bytes. The public readHistory (Line 1139) calls it with the full history Ref on every request, and the release finalizer calls it again. At the retention limits, that is up to 3,600 snapshots and about 64 MiB of JSON per call. Each history request then does a large, blocking serialization on the server event loop. The repository guidelines require care with performance regressions.
Compute each snapshot's byte size once and store it next to the snapshot. Then sum the cached values.
As per coding guidelines: "Make sure all changes are considerate of performance impact."

Tell users how to recover from a failed import.
If the reload guard cannot recover the chunk, the palette closes without a message. React caches the rejected import, so reopening also fails until the page reloads. Show a failure message with a reload action or instruction. (raw.githubusercontent.com)

import presents users with a clear failure message and a reload action or

Restore focus after a failed palette import.
62-62: Minor · Functional Correctness · Quick win
Restore focus after a failed palette import.
When the lazy dialog import fails, the palette closes before its popup mounts. The workspace stays inert while the palette is open, so the opener loses focus. The popup's finalFocus never runs because the popup never mounts. The focus-recovery code also cannot restore focus after inert is removed. Focus stays on body.
Restore the saved opener after the closing render removes inert. Use getCommandPaletteReturnFocus() from apps/web/src/commandPaletteStore.ts. Cover this path with a failing browser test in apps/web/src/components/CommandPalette.browser.test.tsx, then apply the fix.

Leaving both follow-ups on CommandPalette.tsx out of this PR. The boundary only runs after the chunk reload guard has already reloaded the page once and the chunk still fails. That is a broken deploy, where other lazy routes fail the same way. The fix only needs to keep the workspace usable instead of replacing it with the root error view. A message, a reload action and focus restoration for that state would be new UI and a new test for a last-resort path. They fit better as a follow-up that covers every lazy chunk the same way.

Thank you @maria-rcks for the startup and streaming work. Backend bytecode preparation on Linux is now on main via #32987 (4013183171) and ARM64 support via #33050 (3da48c1234). Please cut the already-covered backend bytecode preparation from this PR and retain the separate startup and streaming changes that still matter.
Lazy modules gain main's new members: SshDeviceHost errors are matched by
tag, the lazy text generator forwards transcription post-processing, and
tests follow the early window, deferred scroll measurement and settings
client arguments.
Effect Service Conventions: the inline finding in apps/server/src/http.ts covers the new compressed-asset handling only; existing static-file handling is not part of the requested cleanup.

Main prepares server bytecode on every native target (#32987, #33050).
The packaged compile cache now covers only the Electron main process; the
backend uses main's prepared cache and its post-startup flush again.
prebuildDesktopCompileCache no longer warms the backend CLI or server chunks, and the packaged runtime.json no longer carries server entries.
The backend (ELECTRON_RUN_AS_NODE) goes through main's enablePreparedServerCache again on every platform, with main's fallback.
apps/server/src/compileCache.ts and the post-startup flushCompileCache are restored as on main.
Kept:
The packaged cache for the Electron main process (main.cjs). Main skips main-process caching on AppImage, so this is the only cache the window process gets there.
The single afterPack hook. It still calls prepare-server-compile-cache.cjs and removeSharedWriteAccess, plus license dedup and native stripping.
Every other startup and streaming change.
vp run check:changed passes (98 files, 2,156 tests), plus the packaging and cache tests. The AppImage benchmark was not rerun; the PR body now says the table included this PR's old Linux backend bytecode.

A fresh desktop launch waits about 1.6 s before showing a window. It then writes 40 MiB and 418 files to the home directory, and keeps several services and timers busy that an idle app never uses.
The main window now opens from a small bootstrap entry before the runtime and backend load. Idle work moves behind first use: the resource monitor, MCP OAuth keys, secret salts, native passkeys, the editor inventory, provider discovery and SQLite readers. New databases use smaller pages and checkpoint after migrations. Untouched providers write no status file. Linux and macOS share Chromium's network-service and code-cache settings. The packaged app ships a main-process compile cache, stripped native modules and fewer assets. Backend bytecode comes from main's prepared server cache (#32987, #33050). Live streaming moves to an imperative markdown renderer that stays outside React updates, and closed panels such as the command palette load on demand. An idle terminal cursor stops blinking after two blinks and resumes on output or focus. The local resource monitor samples only while something reads it, unless OTLP metric export is configured.
Measured with the packaged Linux AppImage at main
fa31b66bbband this PRb637c43b86. Each launch used a fresh home and a 60 s idle period. The table shows medians of 6 alternating paired rounds on one 4 vCPU / 8 GB VM. Deltas are per-round medians. Spread is min to max, not a confidence interval. This PR then prepared Linux backend bytecode itself, which main now does, so the table overstates its gain against current main.Peak RSS is higher because the window's renderer now starts alongside the backend instead of after it.
vp run check:changedpasses: 101 test files, 2,169 tests. The benchmark boots the production AppImage. macOS packaging (afterPack signing and the main-process cache) and streaming render cost were not benchmarked against main here.Maintainer sign-off needed:
