feat(remote): remote-terminal as an ordinary Surface, not a separate workspace (#1086/#1091) - #1100
Merged

… workspace Foundation for openwong2kim#1086/openwong2kim#1091: a session on a paired remote host should be a PANE inside an ordinary local workspace (gaining rename/color for free from WorkspaceItem), not a separate remote-workspace entity with its own stripped-down sidebar row and mirror-only grid. - Surface.surfaceType gains 'remote-terminal', with remoteHostId/ remoteSessionId identifying the paired host + remote daemon session. ptyId stays '' — same convention as 'browser' — so every existing ptyId-gated check (a2aAddressing, deckBrain, ChannelMembers, the reconcile loop) already treats it as non-local without touching those sites. - createRemoteSurface() factory, mirroring createSurface(). - addRemoteSurface() store action, mirroring addBrowserSurface(): caller splits an empty leaf via the existing splitPane(), then calls this to populate it in any local workspace's tree. - Two explicit-enumeration guards in AppLayout.tsx (paste-target and the PTY-reconcile loop) that check `=== 'browser' || 'editor' || 'diff'` without going through ptyId now also exclude 'remote-terminal', so neither path tries a local-PTY operation against it. - fleet.ts had its own duplicate literal union for surfaceType (not importing Surface's) — widened to match, caught by tsc. Deliberately NOT in this PR: renderer wiring (Pane.tsx render branch, SSE attach, an "add remote pane" UI entry point, OSC 0/2 title detection on the mirror stream). That's stage 2, a follow-up PR — this one is store + types only, verified to introduce zero behavior change for any surface that isn't 'remote-terminal' (nothing constructs one yet). Full test:parallel: 845 passed / 4 failed files, all 4 confirmed pre-existing on a clean stash of origin/main (deck.handler.loop.test.ts, atomicWrite/rotation.test.ts — timing-sensitive, unrelated to any changed file). tsc --noEmit and eslint clean (eslint diffed against clean base: same 4 pre-existing errors, +1 new non-null-assertion warning matching the test file's existing style).
📝 WalkthroughWalkthroughThe PR adds remote-terminal surfaces as ordinary local pane tabs. It adds host selection, remote session creation, session attachment, shell-title updates, localization, tests, and exclusions from local file-drop and PTY reconciliation. ChangesRemote terminal support
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to This change makes remote sessions ordinary tabs in local panes, but creation and local registration can become unsynchronized, leaving sessions without a visible owner; closing a tab also leaves the remote session running. That can accumulate orphaned sessions or duplicate sessions after retries, so explicit owner acceptance or lifecycle follow-up is needed before merge. Sequence Diagram(s)sequenceDiagram

…penwong2kim#1091 stage 2/2) Completes PR openwong2kim#1100's store/type foundation with the renderer wiring: - Pane.tsx renders a remote-terminal surface as an ordinary tab, next to local terminal/browser/editor/diff tabs in the same leaf — via a new RemotePaneSurface component (the attach/detach lifecycle from RemoteWorkspaceView's PaneCell, adapted for a single surface instead of a whole mirror grid). - "Add remote pane" in the pane's ⋮ menu opens a host picker (AddRemotePaneModal) that bootstraps a fresh session on the chosen paired host via the openwong2kim#1001 operator-mint path (remote.workspaceCreate) and adds it as a surface in the CURRENT local workspace — no separate "remote workspace" entity is created at all. - RemoteMirrorTerminal wires xterm's own onTitleChange (it already parses OSC 0/2 from the mirrored byte stream) through the same sanitizeTitle PTYBridge uses for a local pane, so a remote shell's `rename`/window-title sequence updates the tab's displayed name — a new updateRemoteSurfaceTitle store action (surfaceId-keyed twin of updateSurfaceTitleByPty, which can never match a remote-terminal surface since its ptyId is always '') applies it, respecting a manual rename's titleLocked the same way. Known limitation, left for a follow-up: a pane holding BOTH a local terminal and a browser surface (the existing hasBoth split view) has no third region for a remote-terminal surface added to it — it simply won't render in that specific 3-way combination. Every other combination (remote-terminal alone, or alongside other remote/local terminals as tabs, or alongside diff/editor overlays) works. Also left for a follow-up: closing a remote-terminal surface removes it from the local pane tree but does not terminate the session on the remote daemon — a minor idle-session leak, not a correctness bug.

Terminate sessions created for remote surfaces.
Line 41 starts a remote session. Closing the resulting surface only detaches its pane attachment; it does not terminate the remote daemon session. Repeated create-and-close cycles leave unmanaged sessions running on paired hosts. Add a termination action to the surface-close lifecycle, or retain an accessible session-management path.

Review verdict: this is the adopted direction — 3 required fixes, then mergePer the direction call just posted on #1091, the remote-terminal Surface model is canonical. One correction to this PR's framing for the record: #1086 carried no explicit owner direction — the call is being made now, on #1091, on the merits (and this PR's architecture is a big part of why it went this way). Security review came back clean: Required before merge
Follow-up (tracked, not blocking this PR)Session lifecycle: closing the tab must eventually destroy the remote session (explicit close only — reload re-attach depends on the session surviving unmount), and the minted one-shot |
1. hasBoth split's overlay path dropped remote-terminal onto EditorPanel
with an empty filePath (pickOverlaySurfaces didn't route it, and the
ternary below had no branch for it). Route it through pickOverlaySurfaces
and render RemotePaneSurface with the same absolute-inset-0 overlay
contract Diff/EditorPanel use.
2. clonePaneTreeFresh spread remoteHostId/remoteSessionId onto the clone,
so duplicating a workspace double-attached the source's live remote
session from two tabs. Strip both fields on clone, same as ptyId reset.
3. AddRemotePaneModal.pick latched its "creating…" spinner before the
`!remote` guard (permanently disabled with no bridge) and had no
catch around the awaited workspaceCreate call (a rejected IPC call —
not an { ok: false } response — left it stuck AND propagated an
unhandled rejection, since the caller does `void pick(...)`). Move
the guard first, wrap in try/catch/finally.
Regression tests added for all three; full test:parallel shows the same
2 pre-existing timing-sensitive failures as a clean stash of this branch
(notificationSlice, deck.handler.loop) — confirmed unrelated.

Make the missing-bridge test exercise pick.
No button exists when electronAPI.remote is absent, so this conditional skips every assertion. Seed hostsList() first, remove remote before the click, and require the button to exist. The test will then verify the missing-bridge guard.

…nted (#1129) (#1143) * fix(remote): closing a remote-terminal tab destroys the session it minted (#1129) #1100 made a remote session an ordinary Surface, but left it with no teardown: a remote-terminal surface carries `ptyId: ''` (the browser/editor convention), so every `pty.dispose` path in the renderer walks straight past it. Closing the tab detached the SSE stream and nothing else — the shell kept running on the host, and with it the one-shot `remote-pane-*` workspace row the remote daemon derives from that session's `WMUX_WORKSPACE_ID`. Nothing would ever reap either, so every "add remote pane" left permanent residue on the paired machine. Root cause: `Pane.handleCloseSurface` disposes `surface.ptyId` and nothing else; `AddRemotePaneModal` mints a fresh session (and workspace id) per pane. - `RemoteHostClient.closeSession` — `DELETE /api/sessions/:id`, the #1094 extraction #1091's direction call asked for. 404 resolves (already gone is the requested outcome); everything else throws with the daemon's own wording, notably the 403 a host without `--allow-input` answers with. - `REMOTE_SESSION_CLOSE` IPC + handler: detaches every live stream on that (host, session) first — for any sender — so the client's reconnect loop is not left chasing a session about to disappear. - `Surface.remoteOwned` records whether THIS desktop minted the session. Only an owned session is destroyed on close: the planned "open this mirror session as a tab" bridge points at somebody's running work, and closing a view of it must never end it. Absent/false means not owned, so any future construction site is non-destructive by default; `clonePaneTreeFresh` drops the flag with the pointer it belongs to. - Wired into the explicit close paths only — tab X, Ctrl+W, prefix kill-pane/kill-workspace, sidebar and settings workspace teardown, and the `surface.close`/`pane.close` RPCs. Never into a React cleanup: the #1129 constraint is that unmount, reload, and tab/workspace switches must keep the session alive, which is what makes the surface re-attachable at all. - Shared walks `collectPaneTreeRemoteSessions` / `getWorkspaceRemoteSessions` sit next to the ptyId walks, so a stashed pane cannot be visible to one teardown path and invisible to the other. Best-effort throughout, like `pty.dispose`: the tab is gone from the layout before the DELETE lands, so a failure has nothing to report to. Tests: closeSession (verb/URL/encoding/404/403/non-JSON), the IPC handler (destroy, selective detach, refusal mapping, unknown host), both walks (owned-only, stash), the teardown policy, `addRemoteSurface` ownership, the clone drop, and a source scan pinning every close path to a teardown call — the bug was a missing call site, not a broken helper. tsc clean; eslint clean (2 pre-existing warnings in RemoteHostClient.write). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01RRxH4qJUX5pkr2DpoHTAX6 * fix(remote): review fixes — close the workspace.close leak, destroy before detach (#1129) Review-team findings on the #1129 branch, plus two decisions recorded in the code so they read as chosen rather than overlooked. P1 — `workspace.close` (useRpcBridge) disposed PTYs and removed the workspace without touching its remote sessions: the exact leak this branch fixes, surviving on its one RPC path, and the worst instance of it — once removeWorkspace drops the workspace, the `remoteOwned` records go with it and the session is permanently unreapable. Now calls destroyWorkspaceRemoteSessions under the same guards as the dispose loop, and the call site is pinned by the source-scan test. P2 — REMOTE_SESSION_CLOSE detached every stream BEFORE the DELETE, which is failure-destructive: a close that then fails (host offline, 403 after --allow-input was revoked) left the session alive with every mirror of it cut and no live attach to retry from. The remote daemon does not refuse a delete while SSE streams are open, so the order is now destroy-then-detach, with a test that a failed destroy leaves every attach intact. P3 — RemoteHostClient's file header still claimed the class "never calls a destroy/delete endpoint". It does now; the header names closeSession as the one destructive verb and states that detach/detachAll remain local-only. P3 — destroyRemoteSessions swallowed both a rejection and a resolved { ok: false } with no trace, while the surface carrying the ownership record was already gone: one transient failure orphaned a session nobody could later explain. Both failure shapes now console.warn with host, session, and reason. Best-effort stays; silent does not. Decisions, now stated in the code: - No confirmation prompt on close — local-pane semantics, with `remoteOwned` as the safety boundary. - Sessions leaked before this fix are not auto-reaped: ownership cannot be proven retroactively. Only sessions minted from here on are tracked. tsc clean, eslint clean on the touched files; 1246 tests pass across the remote, teardown, hooks, pane-utils and surface-slice suites.

…1100 tab (#1141) * feat(remote): split a remote session into its own pane, alongside the #1100 tab #1100 shipped remote-terminal as an ordinary Surface — a tab on an existing pane's tab strip. Real usage on a paired VPS right after it shipped surfaced a gap: local terminals can ALSO be split into their own pane (a new layout region, independently resizable), and a remote session had no equivalent — only the tab. Add "Split right — remote" / "Split down — remote" to the same ⋮ menu, alongside "New remote pane" (unchanged): pick a host, mint a session (same AddRemotePaneModal), then attach it to a freshly split pane instead of a new tab on the clicking pane. resolveRemoteAttachPaneId (new, pure, exported alongside the existing pickSplitShownSurfaces/pickOverlaySurfaces) is the whole decision: null direction targets the clicking pane (#1100's tab flow, untouched); a direction targets whatever splitPane() already returned. splitPane creates an EMPTY leaf pane — EmptyLeafFunnel would otherwise race to spawn a local PTY into it, so addRemoteSurface runs in the same synchronous tick as splitPane, before React can commit and let the funnel's effect see an empty leaf. A blocked split (per-workspace pane cap) resolves to null — attach nowhere — rather than silently falling back onto the pane the user asked to split away from. Issue #1140's second ask (count an agent-driving remote pane in the roster/"Agenci") is NOT addressed here: workspaceAgentRoster.ts keys agent detection on ptyId, fed by local PTY hook events; remote surfaces carry ptyId: '' by design (same as browser/editor), so there is no existing signal path a real agent on the far end could report through. Building a heuristic on buffer content would be fragile and guessed; flagging it back on #1140 for the direction call instead of inventing a detection channel here. * changelog: add fragment for #1141 --------- Co-authored-by: openwong2kim <269396487+openwong2kim@users.noreply.github.com> Co-authored-by: Claude Opus 4.8 <noreply@anthropic.com>

…hat opened it (#1148) * fix(remote): AddRemotePaneModal closes on Escape and names the flow that opened it Two gaps the #1141 dogfood run surfaced, both dating back to #1100 but worth fixing now that the split flows tripled how often this dialog shows: - Escape now closes the modal (same document-level listener AttachRemoteModal binds) — the backdrop click was the only way out. - The heading is a `title` prop the caller sets per flow: "Split right — remote" / "Split down — remote" reuse the menu labels, the tab flow keeps the "New remote pane" default. Before, every flow said "New remote pane", so the dialog could not say which action it was answering.

Complete: remote-terminal as an ordinary Surface, not a separate workspace (#1086/#1091)
Per the owner's direction on #1086: a remote session should behave exactly like a local one — a tab inside a normal, renameable, color-taggable local workspace — not a separate "attached remote workspace" entity with its own sidebar row (the model #1067/#1094 built and which this supersedes; #1094 is left open, not closed here).
Stage 1 (already merged into this branch)
Surface.surfaceTypegains a'remote-terminal'variant (remoteHostId/remoteSessionId,ptyId: ''likebrowser), and a newaddRemoteSurfacestore action mirrorsaddBrowserSurface— both add a surface to an EXISTING leaf in a workspace's own pane tree, never create a new workspace.Stage 2 (this update)
Pane.tsxrenders aremote-terminalsurface as an ordinary tab via a newRemotePaneSurfacecomponent — the attach/detach lifecycle fromRemoteWorkspaceView'sPaneCell(teardown-then-attach ordering, idempotent per (host, session)), adapted for one surface instead of a whole mirror grid.RemoteMirrorTerminalgets anisActive-drivendisplay:nonefor the stacked/tab case, same patternTerminalComponent/BrowserPanelalready use.⋮menu gets "New remote pane" (conditionally, only when a caller passesonAddRemote— existing standaloneSurfaceTabsmounts/tests are unaffected). It opensAddRemotePaneModal, a host picker listing already-paired hosts; picking one callsremote.workspaceCreate(hostId, freshId)(the Direction: a text-mode client (wmux attach) — offloading the work to a VPS, and two people on one session #1001 operator-mint path) to bootstrap a session, then adds it as a surface in the current local workspace — the minted id is opaque bookkeeping for the daemon's bootstrap contract, never referenced again.RemoteMirrorTerminalwiresterm.onTitleChange, sanitizes it exactly likePTYBridgedoes for a local pane (sanitizeTitle, cross-imported fromsrc/main/pty/titleDetect.ts— an established pattern in this codebase, see e.g.capabilityGrouping.ts/methodCapabilityMap), and a newupdateRemoteSurfaceTitlestore action applies it. It's thesurfaceId-keyed twin ofupdateSurfaceTitleByPty, which can never match a remote-terminal surface (itsptyIdis always'') — same manual-rename guard (titleLocked), so a user's own rename is never clobbered by a laterrenamein the remote shell.Known limitations (left for a follow-up, not attempted here)
hasBothtwo-region split view) has no third region for a remote-terminal surface added to it — it simply won't render in that specific 3-way combination. Every other combination (remote-terminal alone, alongside other terminals as tabs, alongside diff/editor overlays) works.RemoteHostClient.closeSession(added for feat(remote): a resizable split tree for remote workspaces, with grow/shrink (#1091) #1094) is the right call to wire in for this; skipped here to keep this PR's diff to the render/UI/title path it set out to do.Test plan
surfaceSlice.test.ts—updateRemoteSurfaceTitle(sets title, no-op unknown surfaceId, never touches aterminal-type surface, respectstitleLocked).RemoteMirrorTerminal.test.tsx—onTitleChangefires with the sanitized title, drops an all-control-character title, and works with noonTitleChangeprop at all (the existing mirror-grid caller passes none).paneClusterWidth.test.ts's menu/cluster parity test —new-remoteis a deliberate menu-only addition, same asrename-pane(Pane header: the pane label duplicates the surface tab title on single-tab panes, and isn't clickable #1021), pinned explicitly rather than silently drifting.npm run test:parallel: 12865/12868 (3 pre-existing failures —state.fallback.test.ts,deck.handler.loop.test.ts×2 — confirmed present on a clean stash of this branch's base, unrelated to this diff).tsc --noEmitandeslinton every touched file: 0 errors (pre-existingno-non-null-assertionwarnings only, none new).Summary by CodeRabbit
