Moving a thread to a linked environment (#16751) was reachable only through the t3_thread_handoff MCP tool. Users had no way to start a move, see one waiting or under way, or reach the thread on the other machine afterwards.

How

  • "Continue on…" on every thread entry point.

    • Web: the sidebar thread menu, the chat-header thread menu, and the command palette. The menus read threadHandoff.options as they open, waiting at most 1.5 s, and show one entry per linked environment. A target that can't take the thread is disabled with the reason, for example "Not answering right now." or the missing project.
    • Mobile: the thread row's long-press menu, the iOS thread header's git menu, and an Android header action. These open a small "Continue on…" sheet that reads the options, because native menus are built ahead of time.
    • The entry needs the peerLinks capability, is hidden while a move is under way or done, and is disabled while the thread runs. A running thread moves only through the agent (t3_thread_handoff with whenTurnEnds).
  • The move's state above the composer, from the shell's new handoff field, using shared wording (threadHandoffNotice):

    • pending: "Moving to when this turn ends", with Keep it here;
    • departing: "Moving to …";
    • departed: "This thread continues on ", with Open on ;
    • failed: the reason.

    While the thread is departing or departed, the composer is closed: web blocks sending with the reason, and mobile hides the composer behind the card.

  • "Open on " shows only when this client is also connected to that environment, so it never navigates to a thread the client cannot load.

  • docs/user/remote-access.md says where to find Continue on….

Verification

  • Web threadActionMenu.logic (19 tests) covers the new submenu: one child per target, disabled with its reason, disabled while running, disabled for a connection that cannot change threads, and absent with no targets. Client-runtime peerLinks (5 tests) covers threadHandoffNotice for pending, departed, failed and no move.
  • Mobile thread-list-environments (15 tests) still passes with the new peerLinks capability set.
  • A real move through the sidebar menu across two dev servers, in the recording below.
  • Web, mobile and client-runtime typecheck clean. Lint is clean on the changed files, apart from ChatView.tsx's existing warnings.

Screenshots

Before (main) and after (this PR): the sidebar thread menu gains Continue on…, listing the linked environment

A real move from the sidebar menu. The thread's uncommitted edit to greet.ts arrived on the box unchanged, and the copy here became read-only:

https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/00bc9619b06ea4c2/16758-continue-on.mp4

A departed thread: "This thread continues on cups", read-only, with Open on cups, and the send button disabled

A failed move keeps the thread here and shows why: the box's branch has commits this one lacks

The command palette's Continue on… lists the same targets

iOS: the departed card replaces the composer, with Open on cups (left); on the box, the moved thread's subtitle reads From T3 Code · cups (right)

The iOS long-press and header menus are native menus that the simulator automation could not open, so their "Continue on…" entries are not pictured.

End-to-end run, two real servers

Two t3 serve processes from the top of this stack, each with its own data directory, on one machine. A laptop (port 3971) and a box (port 3972). Their projects are clones of one bare origin, so they share a repository. An outside agent (OAuth with a pairing code) drives the laptop's /mcp, and real Claude Sonnet 5.5 turns run on both sides. The last part repeats the run over Tailscale HTTPS (a *.ts.net HTTPS address).

The server paths behind these menus ran end to end over MCP, which calls the same ThreadHandoff service as the threadHandoff.* RPCs: see #16751. That covers each state the banner shows: pending, departing, departed (with its thread id), failed (with its reason), and cancelled.

Screenshots of the menus, the banner and the mobile card are still to come. They need a browser and a simulator.

🟡 Medium hooks/useThreadActionMenu.ts:153

If the user switches threads or calls closeMenu() while readThreadHandoffTargets is pending, this continuation still calls contextMenu.show with the old thread’s actions, so a stale menu can appear over the new thread or rename flow. Invalidate pending opens on thread changes and close, then check that the open is still current after this await before showing the menu.

3If the user switches threads or calls `closeMenu()` while `readThreadHandoffTargets` is pending, this continuation still calls `contextMenu.show` with the old thread’s actions, so a stale menu can appear over the new thread or rename flow. Invalidate pending opens on thread changes and close, then check that the open is still current after this `await` before showing the menu.

Fixed in c1f6da387b: each open takes a token; closing the menu, a newer open or a thread switch makes it stale, and a stale open stops before contextMenu.show. The sidebar's right-click menu had the same race and got the same guard. Test fails without it.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — This PR adds a substantial web/mobile workflow for moving conversations and working-tree state between linked environments, including new RPC actions, progress states, read-only behavior, and send gating. It also broadens a file-specific lint exception, while unresolved Medium findings cover stale async menu and cancellation-state behavior.

Needs human approval because:

📝 Walkthrough

Walkthrough

The change adds shared thread handoff state and controls across web and mobile. Users can select linked environments to continue a thread, view handoff notices, cancel pending handoffs, and open a departed thread when its destination is available.

Changes

Thread Handoff

Layer / File(s)Summary
Handoff state and shared runtime
packages/client-runtime/src/state/models.ts, packages/client-runtime/src/state/peerLinks.ts, packages/client-runtime/src/state/peerLinks.test.ts, apps/mobile/src/state/threadHandoff.ts, apps/web/src/state/threadHandoff.ts
Thread shells now expose handoff state. Shared runtime atoms load handoff options and start or cancel handoffs. Notices describe pending, departing, departed, and failed states. Tests cover notice results.
Web handoff actions
apps/web/src/components/threadHandoffMenu.ts, apps/web/src/components/threadActionMenu.logic.ts, apps/web/src/components/threadActionMenu.logic.test.ts, apps/web/src/hooks/useThreadActionMenu.ts, apps/web/src/hooks/useThreadActionMenu.test.ts, apps/web/src/components/Sidebar.tsx, apps/web/src/components/CommandPalette.tsx, docs/user/remote-access.md
Web menus and the command palette load eligible targets and start handoffs. The menus disable unavailable targets and expose reasons. The remote-access guide lists the available entry points.
Mobile handoff entry points and target selection
apps/mobile/src/state/thread-list-environments.ts, apps/mobile/src/features/home/HomeScreen.tsx, apps/mobile/src/features/threads/ThreadNavigationSidebar.tsx, apps/mobile/src/features/threads/thread-list-v2-items.tsx, apps/mobile/src/features/threads/ThreadRouteScreen.tsx, apps/mobile/src/features/threads/ThreadGitControls.tsx, apps/mobile/src/Stack.tsx, apps/mobile/src/features/threads/ThreadHandoffSheet.tsx, vite.config.ts
Thread lists and headers offer handoff actions when the environment supports peer links and the thread has no handoff or a failed handoff. The sheet loads and selects targets.
Handoff status in thread views
apps/web/src/components/chat/ThreadHandoffBanner.tsx, apps/web/src/components/ChatView.tsx, apps/mobile/src/features/threads/ThreadHandoffCard.tsx, apps/mobile/src/features/threads/ThreadDetailScreen.tsx
Web and mobile thread views display handoff notices. Pending handoffs can be canceled, departed handoffs can open the destination when available, and departing or departed states block sending or hide the mobile composer.

A move can leave an unsent mobile message inaccessible, and a concurrent web send can retain an attachment file despite rejection. Resolve these handoff issues before merging; the remaining concerns affect narrower controls and notices.

Handle queued outbox messages before starting the handoff.

threadHandoffEnvironment.start receives no outbox state. A queued message exists only in the mobile outbox, while the server's handoff settlement checks persisted messages and runs. The handoff can therefore enter departing before the outbox dispatches the message.

The server rejects later dispatches for departing or departed threads. Block the handoff until the outbox drains successfully, or transfer queued messages as part of the handoff and handle rejected dispatches.

✅ Confirmed as addressed by @juliusmarminge

@juliusmarminge Thanks for the fix and clarification. Refusing the handoff until the device outbox message is sent or discarded addresses this finding. Web needs no device-outbox guard because its queued sends are server-side runs that already block the move.

5Learning: In pingdotgg/t3code, mobile has a device-side message outbox, but web does not. Web queued sends are server-side runs, and the server already refuses thread handoff while those runs prevent settlement. Do not require a device-outbox guard for web handoff controls.

Note: Learnings are effective only in the context of similar code segments. To apply general coding guidelines, please configure review instructions. You can manage existing learnings in the app.

✅ Review thread resolved.

You are interacting with an AI system.

Fixed in b1e90da6dd: the sheet refuses to start while the thread has a message waiting in the device outbox, with "A message is still waiting to send from this device. Send or discard it first." Web has no device-side outbox; its queued sends are runs on the server, which already refuses the move.

Check the destination connection before showing “Open on”.

presentationById includes catalog environments even when their connection phase is not "connected". The current membership check can show “Open on” for a disconnected destination.

Only show “Open on” for connected destinations.

useEnvironmentIds() includes disconnected environments because it reads the catalog keys. A departed thread can therefore show “Open on” after its destination disconnects. The button then navigates to that unavailable environment, contrary to the banner contract.

Use useConnectedEnvironmentIds() for this condition.

Keep system banners ahead of the handoff notice.

ComposerBannerStack sorts by priority, so higher-priority reconnect and running-update banners already appear first. However, ordinary update notices tie with an informational handoff notice, and a failed handoff ties with error or warning banners. Because handoffItems is first in both arrays, it can still hide those system notices in the collapsed stack. Move systemComposerBannerItems before handoffItems in both branches.

Guard direct sends during handoff.

The server rejects message.dispatch for departing and departed threads, but onSend does not check the handoff state before it updates optimistic messages and clears the composer. sendAppMessage also calls startThreadTurn directly without this check. These paths can perform client-side send work before the server rejection.

Check the handoff state before optimistic updates and direct dispatch. Keep the server rejection as a backstop.

Hide the move action without thread-operate access.

When canOperateThread is false, this guard still offers “Continue on another environment.” Selecting a destination then attempts a move the connection cannot authorize. Include canOperateThread in the guard so the header does not offer an unusable action. As per path instructions, the Effect-service rules “do not prescribe client-side UI behavior”; this finding concerns the client action’s access gate.

3While a thread has a running or queued turn, `onContinueOn` still enables the header action, so users can select a destination only for `ThreadHandoff.start` to reject the operation. Gate this action on the thread not having an active or pending turn.

Fixed in b1e90da6dd: onContinueOn and the thread list's long-press menu require no running or queued turn (threadRuntimeIsActive), matching what the server refuses.

A disconnected or disabled destination still gets an enabled “Open on …” action, which navigates the user to an unavailable environment. useEnvironmentIds() includes catalog entries regardless of connection state, so use useConnectedEnvironmentIds() for this check.

On non-split layouts without native header glass, users cannot start “Continue on…” from the thread header even when ThreadRouteScreen supplies onContinueOn. This item is added only to the serialized header menu; the fallback ThreadGitControls uses threadGitMenuDefinition, which does not include it. Add the action to that fallback menu as well.

The component-wide cancelling state persists when shell changes; key it to the shell and handoff so only the request for the displayed thread disables its button.

When a thread context-menu handler is waiting for readThreadHandoffTargets, opening a draft menu leaves latestThreadContextMenuRef.current unchanged, so the stale thread handler still calls api.contextMenu.show and replaces the draft menu. Increment the shared generation when the draft handler opens its menu so the pending thread request is discarded.

Taking over this one as part of ssh-relay-remote-14. I’ll rebuild the handoff service dependency and web/mobile controls on the maintained linked-environment stack, preserve permission and running-thread guards, and publish focused replacement layers with verification and author credit.

Thanks @juliusmarminge for the original linked-environment handoff controls and the web/mobile entry points. The complete replacement is now open:

  • #21955: native conversation import and idempotent continuation.
  • #21981: Git snapshot transfer and acceptance/rollback leases.
  • #22068: server handoff, source fences, pending moves, same-ID recovery, bounded fork history, and RPC/MCP access.
  • #22069: shared protected client commands plus web and mobile controls, draft/outbox preservation, and recovery UI.

These depend on the peer-link layers #21824, #21825, and #21826. The original is closed in favor of this stack; nothing has been merged.

I compared all 27 paths in the original diff against the rebuilt layers. Its sidebar, header, palette and mobile entry points are retained; the independent iOS sidebar now receives root navigation explicitly. The obsolete peerLinks state module and Vite alias were replaced by current environment command/query machinery and native package exports. Server behavior absent from main lives in the import, Git and handoff layers above. Tests and implementation were rebuilt in separate agents, with independent whole-layer reviews; the final server and client rounds are both clear.

Current proof and platform limits are attached to the replacement bodies: actual two-server HTTP and browser transfer, native receiver state/files, preserved source index and unsent draft. A real provider completion, relay/tunnel, macOS, Windows, Electron desktop, iOS and Android remain unverified here. CI and landing are handed to the central coordinator under the shared-token budget policy.
