SSH hosts publish workspace rows through workspacesByMac like the demonstration computer. Demo-only branch points become locally-served checks so SSH surfaces route input, replay, viewport, and composer paste to the SSH runtime instead of a Mac. Plain, tmux, and cmux-tui persistence providers; cmux-tui client with bytes-mode attach and phone geometry; npm-verified cmux-tui upload; TOFU and changed-key prompts.

The phone's emulator answers terminal queries for plain/tmux SSH surfaces and filters its replies for cmux-tui (whose server already answers), SSH surfaces get local pixel scrolling and mouse clicks, sign-out keeps SSH rows, the app injects a persistent SSH runtime, and SSH workspaces gain an SFTP file browser, port forwarding into the native browser, and image paste over SFTP. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
…signed-out use SSH hosts get their own section in Computers and open their workspace list; add/edit form with key picker, jump host, persistence, idle close, and password-once key install; SSH key management (Secure Enclave generate, OpenSSH import); root-level trust/changed-key/persistence prompts; and SSH without a cmux account.

set-terminal-idle-policy stores an idle close time per hosted terminal in the registry; an owner-side reaper closes terminals with no attached views past their deadline through the normal close path.

… lab test, translations cmux-tui browser tabs stream into the existing browser stream pane with tap/scroll/keys/navigation; the phone applies the host's idle-close policy when the server supports terminal-idle-close-v1; the cmux-tui upload is lab-tested; all SSH strings are localized in the 9 catalog languages.

The hosted Blacksmith macos-26 image now carries the Xcode 27 RC and select-ci-xcode.sh ranks by newest macOS SDK, so every dispatched iOS dev-build archive switched to the 27 SDK and fails compiling main's SwiftUI (toolbarMinimizeBehavior: https://github.com/manaflow-ai/cmux/actions/runs/35783022784 and https://github.com/manaflow-ai/cmux/actions/runs/35786136840). Feed the selector's existing CMUX_CI_MAX_MACOS_SDK_MAJOR ceiling from .xcode-version's major so the ranking keeps the newest pinned-major Xcode and skips unvalidated newer SDKs, with the older-runner fallback unchanged.

- Handshake deadline pauses while the host key prompt is open; a declined key reports hostKeyRejected (including behind a jump host), not a timeout. - Replayed history and cmux-tui snapshots strip terminal query requests, so the phone never answers stale queries into the PTY (Mac #10332 class). - Replacements fully reset the local terminal before replaying history. - Selected SSH host auto-connects on launch/foreground; explicit disconnect or a declined prompt stays manual. - Signed-out SSH mode skips Mac-centric What's New/pairing sheets. - Literal text entry (no autocorrect) on SSH host and key fields.

Simulator verification on tag Verified in the app: signed-out SSH entry, first-use trust (fingerprint matches Found on video and fixed: handshake timeout while the trust prompt is open, cancel reported as a timeout, no auto-connect after relaunch, Mac-centric sheets in SSH-only mode, autocorrect on host fields, and replayed terminal queries answered into the PTY. tmux first-open blank did not reproduce in 5 samples after the replay reset fix. Unverified: password-once install in the app (the lab sshd has no password auth), cmux-tui browser tabs (no provider in the lab), native pixel scrolling (the harness can't synthesize scroll gestures). cmux-tui 🤖 Generated with Claude Code |
- tmux via control mode: session = workspace, pane = tab, New Terminal opens a window, phone attaches through its own grouped session. - cmux-tui New Terminal; plain workspaces have no terminal tabs. - cmux-tui: re-snapshot when a full-screen app exits so shell history behind it returns. - Browser: shared bottom chrome for streamed and native browsers, a Streamed / On iPhone mode picker remembered per browser, SSH On iPhone routed through a SOCKS5 proxy over SSH plus a loopback port mirror. - Files chip opens SFTP at the shell's directory; title-menu SSH items and the open-port sheet removed. - Sign-in 'Use with SSH only', mode-aware empty states with Mac-parity status, + chooses a computer under All Computers, declined identity pauses auto-connect across relaunch, key origin on every key row, friendly Face ID errors, no dev-tag suffix on SSH hosts.

- Phone grouped sessions no longer use destroy-unattached (tmux 3.7c frees a session another exiting client still references and segfaults); the phone kills its grouped session on close and collects stale ones on connect. Repro: 8/10 crashes before, 0/20 after. - Paired-Mac reconcile, team switches, and Mac outage handling leave SSH computers alone; newest listing wins; lists refresh on appear/active. - SSH workspace ids resolve through the row's RPC id, so New Terminal works when several computers are live. - Strip screen-style title sequences (ESC k ... ST) from tmux pane output. - A successful refresh after a failure reports the host connected. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

One SSH connection per host serves cmux-tui workspaces, tmux sessions, and plain shells side by side. Each workspace row is one kind's top-level primitive (subtitle shows the kind); + offers a menu of kinds; existing server sessions and cmux-tui workspaces from any cmux-tui session are discovered; the tab switcher groups tmux windows and cmux-tui screens with New Window / Split Pane / New Screen / New Tab. Per-host persistence mode and the first-connect prompt are removed. The phone claims cmux-tui geometry only while a terminal is on screen. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Every close entrypoint asks through one store decision: tmux and cmux-tui rows outlive the phone, so ending one explains what stops on the computer; plain shells close in one tap. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
… the new owner leaves Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
When a phone claimed a shared terminal's geometry and then released its viewport or disconnected, the grid froze at the phone's size and the laptop client that it displaced stayed non-authoritative until its user focused a pane. Each terminal runtime now remembers the owners a claim displaced. When the current owner releases, disables its sizing, or disconnects, the most recent displaced owner that still reports a viewport for a view of that terminal becomes the owner again and the PTY resizes to its report. Departed clients are forgotten, and an explicit use-all-sizes release still freezes. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
The resource router's pure creation path (resource_create_empty_workspace_selected) committed the registry patch and published only the journal event, never a MuxEvent, so subscribe clients learned about `workspace create --empty` only when the next real change flushed. Emit the same WorkspaceAdded TreeDelta the legacy create-workspace path emits, after the patch applies, with the entity snapshot and workspace revision the delta contract requires. Server-side only: SSH hosts see it once a cmux-tui release past the pinned 0.13.4 ships (PRD changelog updated). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Dogfood build of cmux DEV pr-14149-1fa296e1.app The link opens this exact commit in the cmux dev menu bar app. The build starts on each push and the page waits until it is ready; a newer push replaces it. It signs in against production, so Cloud or backend changes still need a tagged build with a development backend. |
v4 pty-live finding: when the tmux server ends, its control-mode exec channel dies while the SSH connection stays up, and sessions on the next server never appear until a manual pull-to-refresh. Adds the failing regression (an unexpected control death on a live host must request one relist and forget the per-server grouped-session collection pass) plus the behavior-preserving seams it drives: a nil-connection test path like MobileSSHPlainProvider's, the control wiring extracted into adopt(_:session:), an injectable hostConnectionIsOpen, and a pump completion await on the control client. Scripted in-memory tmux -C pipe, no PTY, no sleeps. The fix follows. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
A host whose key was deleted keeps a dangling keyID; a connect then loads a key whose secret is gone and throws SSHKeyStoreError.missingSecret, which MobileSSHComputers.describe(_:) rendered as the raw enum case name in the terminal and the row status. This test pins that it must read as the 'choose a key' sentence instead. Fails on the current code; the next commit fixes it. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
MobileSSHComputers.describe(_:) had no case for SSHKeyStoreError, so a
connect on a host whose key was deleted (the host keeps a dangling keyID,
and privateKey(for:) throws missingSecret) fell to String(describing:) and
showed the literal 'missingSecret' in the terminal and the row status.
Map SSHKeyStoreError.missingSecret to the existing localized noKey copy
('Choose a key for this computer first.'), the same guidance the noKey path
gives and the exact recovery the user needs (re-pick a key in the editor).
Covers every missing-key-secret cause (deleted key, keychain eviction,
restore) with no new string.

A control client that ends while still registered was closed by tmux, not the phone (phone-initiated closes remove it from the registry first). When the SSH connection is still open that means the server (or this session) ended: forget the per-server stale-grouped-session collection pass, which belonged to the dead server, and fire the existing onTopologyChange relist path once, so a restarted server's sessions appear without pull-to-refresh. The relist reuses refreshWorkspaces' generation coalescing and failure handling; no timers, one relist per death. Connection teardown stays on the runtime's own close path.

Tapping Reconnect in the title menu while the computer is still down changes nothing on screen: the title already read Disconnected, the row already carried the failure sentence, and nothing new reaches the terminal, so the tap looks ignored (v4 edges pass, scenario 1). Expected to fail until the next commit delivers the failure sentence to the shown surface. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Reconnect against a still-down computer already walks connecting -> failed, but a refused loopback connect resolves in milliseconds and the failed state renders the exact chrome (red Disconnected) shown before the tap, so nothing visibly happens. reconnect(hostID:surfaceID:) now delivers the failure sentence to the shown surface after a failed open, with the same red-notice rendering a failed attach uses (shared errorNotice helper). A declined identity prompt leaves the status idle, so cancelling stays quiet; the still-visible Connecting/Reconnecting state during a slow connect is unchanged.

… users
The aggregated (All Computers) empty state always rendered the
Mac-pairing copy ("Enable iOS pairing in cmux Settings > Mobile on your
Mac..."), which describes a Mac an SSH-only user does not have; per-host
SSH empty states were already right (v4 edges pass, secondary
observation; PRD D29 mode-aware empty states).
WorkspaceListEmptyGuidance decides from what exists: SSH computers with
no paired Mac get SSH guidance (the per-host "No Workspaces" title, a
terminal icon, and "Choose a computer from the menu at the top, or add
one from the Computers screen."), and any paired Mac keeps the Mac copy.
The SSH variant also drops Retry and See Docs, which drive the Mac
workspace-list recovery and the Mac pairing docs. The guidance rides the
table snapshot into the empty row model, so a change re-renders the row.
New string localized in all nine app languages.

…'Session ended' line connectionClosed removes the host's attachments silently and relies on each child channel's own close event to write the '[Session ended]' line, so a transport drop whose channel close lags leaves the shown terminal with nothing. MobileSSHConnectionDropTests.droppedTransportEndsTheShownTerminal drives the connection-close path alone and fails: no notice, endedSurfaces empty. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
A whole-connection drop (server death) now routes through the same idempotent per-surface end path a child channel's close uses, so the '[Session ended]' line and the endedSurfaces mark land on the transport close instead of waiting on each channel's own close event, which can lag arbitrarily under load. It also drops stale attachAwaitingGrid entries so a reconnect re-seeds through the ordinary subscribe path. handle(.ended) and connectionClosed share endTerminalSurface, which is idempotent through endedSurfaces so the two paths never double-print. MobileSSHConnectionDropTests.droppedTransportEndsTheShownTerminal now passes; channelCloseEndsTheShownTerminal and reconnectWhileSubscribedRepaints guard the channel-close line and the reconnect repaint.

Round 4 made the SSH Files chip always visible (TerminalFilesChipReveal .always) because it is the only entry to the server's files, but a chip that never fades sits over the first terminal rows. Aziz: it should look and behave exactly like Files on a paired Mac. The reveal special case is reverted: every terminal's chip is hidden at rest, shown while scrolling, and faded after the same linger, with the same assistive-technology bypass, through the same component. Browse Files in the workspace title menu (D28 follow-up) remains the always-visible entry point, so discoverability does not regress. TerminalFilesChipReveal and its tests are deleted as dead code; the SSH chip's persistent mount (no artifact count to gate it) is unchanged (PRD D44).

The grouped tab switcher's one "Split Pane" always split one way (tmux stacked below, cmux-tui to the right), with no way to pick the other orientation. It is now the two directional actions the cmux macOS app has, with the same names, translations (all nine app languages, copied from the macOS catalog), and SF Symbols: Split Right puts the new pane side by side (tmux `split-window -h`, cmux-tui `split dir:"right"`) and Split Down stacks it (`-v` / `dir:"down"`), on both tmux windows and cmux-tui screens, still detached so no attached client's view moves (PRD D45, superseding D32/D42's single action; HIG Menus: one item per action). MobileSSHSectionAction carries its direction; the tmux flag mapping is a pure helper with a unit test, and the cmux-tui wire tests already pin `dir` for both values. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
An SSH host's "No Workspaces" overlay was a bare ContentUnavailableView and the SSH-variant All Computers row used its own terminal icon and title, so SSH empty states looked like a different app from a paired Mac's. The paired-Mac empty row's visual scaffold (macbook.and.iphone icon at 44pt, "No workspaces yet" title2.bold, secondary message, spacing, width cap) is now one shared view, WorkspaceListEmptyStateScaffold, used by the table row and the per-host SSH overlay, so every empty state is pixel-identical. Only what must differ differs: SSH messages carry the host's status line (per host, still inside the pull-to-refresh scroll view with auto-connect) or the choose/add-computer line (All Computers), and the Mac-only Retry and See Docs buttons stay on the Mac variant, which drives Mac workspace-list recovery and pairing docs (PRD D46). The mobile.ssh.empty.title key is now unused and removed. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The sign-in screen's quiet "Use with SSH only" entry, the signed-out SSH shell it opened (SSHOnlyWelcomeView, MobileSSHOnlyPreference, the mobileSSHOnlyEntry environment action), and the audience machinery that suppressed Mac notices for it (MobileWhatsNewAudience) are removed: MobileRootAuthGate.shouldShowSignIn no longer takes a bypass, so a signed-out launch always lands on sign-in and every user signs in before using the app (PRD D47, superseding D5's no-account entry; deliberate deviation from HIG Managing accounts, since every cmux surface is account-backed). The SSH computers feature itself is untouched for signed-in users: hosts and keys stay on-device, the Computers screen and pairing's "Connect with SSH Instead" still add hosts, and WorkspaceListEmptyGuidance still keys on has-SSH-computers / no-paired-Mac, which a signed-in account before its first pairing hits. An attach-ticket session (no Stack account) keeps its settings sign-in row. Localization keys for the removed strings are deleted. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

protocol guide so it states that the most recent eligible displaced owner with a
current viewport report is restored and the grid resizes to that report;
preserve the rule that disconnected or non-reporting owners are not re-elected.
Keep the relay-specific exception separate from this general handback behavior.

- Around line 85-86: Replace the fixed 200-yield wait in the test with a
deadline-bounded poll of the persisted `isAutoConnectPaused` value, then assert
the expected false value. Add deadlines to the unbounded `while

@Packages/iOS/CmuxMobileShellUI/Sources/CmuxMobileShellUI/CMUXMobileRootView.swift:
- Around line 833-838: Update
CMUXMobileRootView.selectSSHComputerInWorkspaceList to delegate selection and
connection to a single store action, and route the other SSH computer selection
surface through that same action. Move workspace-filter ownership out of the
views’ @AppStorage writers; ensure MobileSSHComputers.deleteHost clears the
filter when deleting its selected host.

- Around line 76-79: Update the signed-out footer in
MobileSettingsAccountSection to say users must sign in to use SSH computers and
pair a Mac, rather than suggesting SSH works without an account. Update the

- Around line 123-142: Update withClient to close the stale SFTPClient before
replacing it after SFTPError.connectionLost. In sftp(), prevent a client opened
after close() from being assigned or returned; close that opened client and
propagate cancellation instead. Track the closed state and set it in close() so
the opening task can enforce this guard.

@Packages/iOS/CmuxMobileShellUI/Sources/CmuxMobileShellUI/SSHFiles/WorkspaceDetailView+SSH.swift:
- Around line 11-15: Update the sshHostID computed property to resolve the
preferred host through store.sshHostID(computerDeviceID:) using
workspace.macDeviceID, then fall back to computers.hostID(forIdentifier:) with
workspace.rpcWorkspaceID.rawValue instead of workspace.id.rawValue.
Review comments at
@Packages/iOS/CmuxMobileShellUI/Sources/CmuxMobileShellUI/SSHKeysView.swift:
- Around line 75-79: Update the deleteKey error handling in SSHKeysView to set
deleteError using SSHKeyErrorCopy().message(for:) instead of String(describing:
error), so the alert shows user-facing copy rather than raw error details.

@Packages/iOS/CmuxMobileShellUI/Sources/CmuxMobileShellUI/WorkspaceShellView+WorkspaceActions.swift:
- Around line 344-353: Update the SSH branch in closeWorkspaceClosure so a nil

📐 Maintainability & Code Quality | 🟠 Major | 🏗️ Heavy lift
Move the per-computer route registry off static var routes and into an injectable owner.
BrowserServerRoute.routes is new process-wide mutable state. It caches one WKWebsiteDataStore for each SSH host, and nothing removes entries from it. It is also a second owner for per-host browser state that MobileSSHComputers already owns (browserProxies, browserHosts, lastBrowserProxyPorts).
This has two effects:
- After a host is deleted, its route stays in memory with its cookies and storage, and its
prepareclosure still capturescomputers. - Tests share the registry across cases.
routeIsSharedPerComputerAndReadiesLoopbackPortsOncerelies on random ids to avoid collisions.
Make an injectable object own the routes. One option is a BrowserServerRouteRegistry held by MobileSSHComputers or the workspace detail store. Construct routes through that object, and drop a host's route when deleteHost(id:) runs.
As per coding guidelines: "Flag new ambient global surface in production Swift: ... top-level mutable var ... and new singletons ... for runtime state that should be owned and injected."

Replace BrowserServerRoute.routes with an injectable BrowserServerRouteRegistry
owned by the existing per-computer or workspace detail owner, and have route
creation use that registry. Ensure deleteHost(id:) removes the deleted host’s
route so its data store and prepare closure are released; avoid process-wide
mutable route state.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Reset the loading state when Stop cancels a pending route task.
withReadyRoute calls state.navigationDidStart() before it awaits serverRoute.ready(for:). This sets isLoading = true. If the user taps Stop during that await, .stopLoading cancels routeTask. The task then returns on both guard !Task.isCancelled paths without resetting the state. webView.stopLoading() sends no delegate callback because no navigation has started. As a result, state.isLoading stays true: the chrome bar keeps showing Stop and the progress line, and the failure overlay stays hidden.
The trigger is a slow SSH reconnect followed by a tap on Stop.
🐛 Proposed fix
case .stopLoading:
routeTask?.cancel()
+ routeTask = nil
run(command, on: webView)
+ // A cancelled route task never started a web-view load.
+ state.isLoading = webView.isLoading
+ if !state.isLoading { state.estimatedProgress = 0 }

When `.stopLoading` cancels `routeTask` while `withReadyRoute` is awaiting route
readiness, reset the loading state because no WebView delegate callback will do
so. In the `.stopLoading` case, clear the task reference, run the stop command,
then synchronize `state.isLoading` with `webView.isLoading` and reset

Retry the original request, not a GET rebuilt from the failing URL.
retryThroughReadiedRoute builds URLRequest(url: failing). This drops the method, the body, and the headers of the request that failed. When a form POST to a localhost dev server fails while the SSH connection is down, the retry sends a GET to the same URL. The user then sees a different page, or the server receives a wrong state change.
The retry also runs for every error that is not a cancellation, including TLS and DNS errors that a new route does not fix. Retry only when the navigation's own request is available, and only for connection errors (NSURLErrorCannotConnectToHost, NSURLErrorNetworkConnectionLost, NSURLErrorTimedOut).

Restore the empty-address guard that the migration to the shared chrome bar removed.
The removed submitAddress ignored an address that was empty after trimming. The new submit closure always sends .navigate(address) and returns true. A blank submit therefore sends browser-navigate with an empty or whitespace URL to the Mac or to cmux-tui, and editing ends as if the address were accepted.

Reject jump-host cycles before saving.
jumpCandidates excludes only the current host, and SSHComputerDraft.record clears only a direct self-reference. A user can save A → B and then B → A.
When neither host has an existing connection, connection(for:) creates a task for each host. The A task waits for B, and the B task waits for the existing A task. Both hosts can remain in .connecting.
Walk the complete jump-host chain and reject a candidate when it reaches the current host or repeats a host.

The test picks Int.random(in: 41000...48000), which can collide with a port that is in use. It then sleeps 600 ms and assumes http.server is ready. LabWebServer in the same test target already binds port 0 and waits for the server banner.

A reattach after the tick snapshot can still be closed.
due is computed from an attach observation taken before the loop. Line 144 checks attachment again, but it uses the placements map captured before the tick. Line 144 also ignores attach_epoch. Consider this sequence: a client attaches and then detaches between the snapshot and Line 144. The recheck then reports "not attached", so the terminal closes although a view attached within the idle window. The race window is small. The policies are measured in hours, so this is a minor issue. The fix is to compare the attach epoch as well as the attached flag.
Proposed fix
- if self.control_clients.attach_observation(views(&placements, &terminal_id)).0 {
+ let expected_epoch = candidates
+ .iter()
+ .find(|c| c.terminal_id == terminal_id)

}candidates borrows policies, and due owns its strings. The borrow checker therefore accepts this change.

In the idle-close loop, the recheck in `attach_observation` uses stale
`placements` and can miss an attach followed by a detach after the tick
snapshot. Compare the current attach epoch with the epoch recorded for that
terminal in `candidates`, and skip closing if the terminal is currently attached
or its epoch has changed; preserve the existing close flow otherwise.

Update the protocol guide to match geometry handback.
When an owner releases its view, this rule restores the most recent eligible displaced owner and resizes the grid. cmux-tui/docs/protocol.md Lines 185–192 still tell clients that the grid freezes and that the server does not elect a survivor. Update that general description. Keep the relay-specific exception separate so clients can implement the correct handback behavior.

Resolve the SSH host from the scoped workspace identifier.
When multiple computers are live, aggregation can replace workspace.id with a host-scoped row ID. That ID can start with cmux-ssh- without containing the scoped ~<local id> form, so computers.hostID(forIdentifier:) can return nil. workspace.rpcWorkspaceID remains the scoped SSH identifier.
When sshHostID is nil, sshBrowserRoute returns nil, the browser mode pickers are omitted, and openBrowserFromToolbar can take the Mac browser-panel path.
🐛 Suggested fix
var sshHostID: UUID? {
let computers = store.sshComputers
- return workspace.macDeviceID.flatMap(computers.hostID(forIdentifier:))
- ?? computers.hostID(forIdentifier: workspace.id.rawValue)
+ return workspace.macDeviceID.flatMap(store.sshHostID(computerDeviceID:))
+ ?? computers.hostID(forIdentifier: workspace.rpcWorkspaceID.rawValue)

Show an error when the SSH scoped ID does not resolve.
closeWorkspaceClosure detects an SSH row. If sshScopedWorkspaceID(id) returns nil, the closure returns without closing the workspace and without giving any feedback. The user confirmed the close, but the workspace stays in the list and nothing explains why. Report this failure through handleWorkspaceActionResult or log it, so a close request never fails silently.
