Problem

Cloud machine rows exposed pane tabs as terminal-under-terminal children, hid real tabs behind 1 more tab / +N, omitted the machine Displays category, and could bootstrap a fresh machine as shell with two terminals.

What changed

  • Project workspace placements as flat sibling leaf rows with exact remote tab identities. Pane layout still controls ordering, while every terminal/tab remains visible and addressable.
  • Remove hidden-tab labels and badges from the Cloud tree and CLI projection.
  • Always render a machine-level Displays category. It lists every catalogued VNC display resource, survives reconnects, and uses an explicit empty/unavailable row when discovery has no result. Existing noVNC routing remains the open path; no unsupported display-creation control is exposed.
  • Move initial Cloud workspace setup to the trusted-carrier daemon owner. Fresh owner sessions create workspace-1 with one terminal; later automatic names use the daemon sequence. Opening/reconnecting a machine reattaches its authoritative terminal instead of creating another. Explicit New Terminal remains a create action.
  • Workspace and terminal rename paths continue to use the exact workspace/tab identity, preserving user custom names.

Validation

  • Added behavior regressions for flat rows, stable tab identities, Displays population/empty state, CLI parity, and one-based bootstrap naming.
  • Regression test and fix are separate commits so CI proves the regression.
  • Hosted test-e2e.yml: cmuxTests/CloudTreeOneMachineManyWorkspacesTests (recording disabled for the unit lane).
  • Hosted cmux-tui.yml: automatically_created_workspaces_use_one_based_sequence.
  • python3 scripts/swift_file_length_budget.py, localization JSON validation, and diff checks pass locally without touching budget TSVs.

Runtime rollout note

The daemon-owner bootstrap behavior takes effect on newly baked images containing this cmux-tui revision. Existing baked snapshots require the normal image bake/promotion rollout; source changes alone do not mutate production snapshots.

Note

Medium Risk
Changes cloud machine open/reconnect and workspace bootstrap paths; incorrect catalog resolution could block opens or attach the wrong tab, though ambiguous cases fail closed with new errors.

Overview
Cloud tree and CLI now list every workspace tab as a flat sibling row (pane layout only affects order). Hidden-tab nesting, +N badges, and “more tabs” copy are removed; node IDs include the remote tab identity so each row stays addressable.

Displays is always a machine-level section (renamed from “VNC Displays”), with explicit loading/empty/unavailable placeholders and catalog-backed VNC rows even when desktop metadata is stale. The Displays group no longer exposes “Open Desktop”; asleep placeholders can wake the machine via opensMachine.

Opening a cloud machine (non–full-client) refreshes the catalog and projects the active workspace’s existing terminal via VMRemoteWorkspaceResolver.resolveVMMachineTerminal; it calls surface.new_terminal only when the graph is authoritatively empty, and errors when sessions are ambiguous or unavailable.

Daemon / provider behavior: trusted-carrier remote sessions run an initial bootstrap (workspace-1 + one terminal); auto-created workspaces use a workspace-N sequence. Terminal/workspace creation defers workspace choice to the daemon (current) instead of inventing names from a stale Mac catalog.

Summary by cubic

Flattens the Cloud tree so every terminal tab appears as a sibling leaf row with its exact remote identity, and makes Displays a machine-level category that always renders in the sidebar and CLI. Moves initial Cloud workspace setup into the daemon owner so opening or reconnecting a machine reattaches its existing terminal instead of creating a duplicate, and resolves workspace selection for new terminals inside the daemon so a stale client catalog can't bootstrap a second workspace.

  • The CLI projection matches the flat rows and no longer shows (+N hidden) labels or nested tabs.
  • Displays always appears under a machine, listing catalogued VNC screens or an explicit loading, empty, unavailable, or asleep state row; the old VNC Displays group and its Open Desktop action are removed.
  • Catalogued displays stay visible even when machine metadata doesn't advertise the desktop capability.
  • Fresh daemon sessions get workspace-1 with one terminal; later auto-created workspaces continue the daemon's workspace-N sequence, and user-renamed names are preserved.
  • Explicit New Terminal still creates; CLI vm open reuses the machine's existing terminal and only creates when the graph is empty, failing closed with an error when sessions are unavailable or ambiguous.
  • Clicking the asleep status placeholder wakes the machine; empty state rows no longer do.

Rollout

  • Daemon-owner bootstrap applies to newly baked images; existing snapshots need the normal bake/promote rollout.

Written for commit fbd8c34. Summary will update on new commits.

Summary by CodeRabbit

  • New Features

    • Cloud machine terminals now reuse existing sessions when available and clearly report empty or unavailable sessions.
    • Workspace tabs appear as individual rows for easier navigation.
    • Displays remain visible even when machine metadata is incomplete, with clear empty and unavailable states.
    • Sleeping machine placeholders indicate when opening an item will wake the machine.
    • Automatically created workspaces now use sequential names such as “workspace-1.”
  • Improvements

    • Display terminology is simplified from “VNC Displays” to “Displays.”
    • Workspace creation can use automatically assigned names when no name is provided.

📝 Walkthrough

Walkthrough

The CLI now reuses existing machine terminals, workspace and tab rows render as flat siblings, displays remain visible with explicit empty states, and workspace creation delegates active-workspace resolution and automatic naming to the daemon.

Changes

Workspace resolution and cloud tree

Layer / File(s) Summary
Active terminal resolution and VM opening
CLI/CMUXCLI+VMTui.swift, CLI/VMRemoteWorkspaceResolver.swift, CLI/VMMachineTerminalResolution.swift, cmuxTests/CmuxTuiSurfaceProviderTests.swift
Plain-terminal opens reuse an available machine terminal, create one only for an authoritative empty graph, and report unavailable sessions otherwise.
Flat placements and display pools
Sources/Cloud/CloudTreeNode.swift, Sources/Cloud/CloudTreeOutlineView.swift, Sources/Cloud/CloudTreeRowContentView.swift, Sources/Cloud/CloudMachineSurfacePresentation.swift, Packages/macOS/CmuxCore/..., CLI/CMUXCLI+VMTui.swift, cmuxTests/CloudTreeOneMachineManyWorkspacesTests.swift
Workspace tabs render as sibling leaf rows. Hidden-tab metadata and pane expansion handling are removed. Displays remain visible as a machine-level pool with localized empty states.
Daemon workspace creation and naming
Sources/Cloud/CloudTuiCommandLine.swift, Sources/Surfaces/CmuxTuiSurfaceProviders.swift, Sources/Surfaces/CmuxTuiSnapshotParser.swift, cmux-tui/crates/cmux-tui-core/src/mux.rs, cmux-tui/crates/cmux-tui/src/main.rs
Workspace names and active-workspace selection move to daemon responses. Default names use the highest existing workspace-N suffix, and trusted-carrier sessions initialize their first workspace before clients attach.

Priority: ➖ Normal

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 17f47

Cloud machine opening and display presentation can still produce duplicate or incorrectly selected terminals, show non-authoritative workspace state, and omit Displays for unavailable empty machines. These behaviors should be resolved before merge.

Full details: Docstring Coverage

Explanation

Docstring coverage is 25.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 68 functions across 16 files. (1 skipped: 1 unsupported.)

Full details: Cmux Algorithmic Complexity

Explanation

The machine-open path now calls resolveVMMachineTerminal (CLI/CMUXCLI+VMTui.swift:463), which scans live terminal resources and then sorts all candidates before selecting one (CLI/VMRemoteWorkspaceResolver.swift:156-162). This is O(T log T) for T user-owned terminal sessions. It also sorts unavailable and ambiguous selectors at lines 167-171. The path has no benchmark or size bound, and it can handle about 1000 sessions. The new machine-open routing therefore activates an avoidable slower algorithm.

Resolution

Use a linear selection. Replace candidates.sorted { ... }.first with candidates.min(by: ...), or update the loop to retain the preferred candidate as it scans. Replace unavailableSelectors.sorted().first and ambiguousSelectors.sorted().first with .min(). Add a scale test or measurement for the resolver with approximately 1000 terminal resources.

Full details: Cmux Swift Package Boundaries

Explanation

The PR adds independent remote-session domain logic to the cmux-cli app target. CLI/VMRemoteWorkspaceResolver.swift adds resolveVMMachineTerminal, which parses catalog protocol data and selects an authoritative workspace, terminal, and tab without AppKit, SwiftUI, Ghostty state, or singletons. CLI/VMMachineTerminalResolution.swift adds its value result type. CMUXCLI+VMTui.swift then uses this logic to choose surface.project or surface.new_terminal. The Xcode project places both files in the CLI target and test target, while no SwiftPM target owns them. This matches the rule's independent domain and protocol/parsing logic conditions. The separate RemoteWorkspaceLayout.flatPlacementIndices change is already in the CmuxCore package and is not a violation.

Resolution

Extract the coherent catalog identity and terminal-selection slice from CLI/VMRemoteWorkspaceResolver.swift, including VMMachineTerminalResolution and the pure helpers it calls, into the CmuxCore SwiftPM target (or a new small CmuxVMWorkspaceCore target). Expose VMMachineTerminalResolution as the first public value type and make the resolver API public. Keep CMUXCLI+VMTui.swift as the app-specific adapter for catalog transport, localized errors, and surface operations. Add package-level tests for connected, empty, focused, ambiguous, and unavailable catalog states.

Full details: Cmux Full Internationalization

Explanation

The PR changes Resources/Localizable.xcstrings, but the affected entries contain only en and ja. The catalog already contains 20 locale codes: ar, bs, da, de, en, es, fr, it, ja, km, ko, nb, pl, pt-BR, ru, th, tr, uk, zh-Hans, and zh-Hant. The seven new keys (cli.vm.open.sessionsUnavailable, cli.vm.tree.noDisplays, and the five cloudTree.displays.* keys) and the three changed keys (cli.vm.tree.displays, cli.vm.tree.usage, and cloudTree.group.displays) therefore lack translated entries for the other catalog locales. The new Swift literals do use String(localized:defaultValue:), but the matching catalog coverage is incomplete.

Resolution

Add real translated stringUnit values, with translated state, for every supported catalog locale for all seven new keys and all three changed keys in Resources/Localizable.xcstrings. Do not use copied English, placeholders, or empty values. Validate the catalog after adding the translations.

Full details: Cmux No Ambient Global State

Explanation

The PR adds the internal static API CloudMachineSurfacePresentation.emptyDisplays(info:) at Sources/Cloud/CloudMachineSurfacePresentation.swift:18. CloudMachineSurfacePresentation is an empty struct whose API is entirely static helpers, so this change expands a static-only namespace. The aggregate diff against origin/main confirms that this method is new; the existing displays and emptyPorts methods predate the PR. This matches the rule's failure condition for a type used as a static-function namespace.

Resolution

Move emptyDisplays to a constructable, injectable presentation owner and construct that owner at the Cloud tree-building seam. Alternatively, keep the behavior as a private/fileprivate helper if its use can be confined to one file. Do not add the new behavior as another internal static method on the empty CloudMachineSurfacePresentation namespace.

457-477: 🗄️ Data Integrity & Integration | 🟠 Major | 🏗️ Heavy lift

Make terminal bootstrap atomic.

surface.catalog and surface.new_terminal form a client-side check-then-create sequence. surface.new_terminal always calls CmuxTuiSurfaceProvider.createTerminal, which issues workspace ... run; pending creation tracking starts only after that request completes. Concurrent opens can therefore create separate terminals from the same empty snapshot.

Move get-or-create into the daemon or enforce an idempotency key. Add a concurrency test that opens an empty machine twice and asserts that one terminal exists and both callers attach to it.

Displays category. When displays is empty, use
CloudMachineSurfacePresentation.emptyDisplays(info:) to provide the
state-specific placeholder instead of omitting the category; preserve existing

the cmux-tui daemon at 65ac4c2 (PR #12227: the trusted-carrier daemon

`workspace-N`) and, for the desktop ladder, the VNC display per

…oot ladders with workspace-1 bootstrap (#12243)

* test: a machine created with the defaults is a desktop with a VNC screen

Regression tests for #12239: the New Machine sheet, bare `cmux vm new`,
`vm base open`, and a kind-less `POST /api/vm` must resolve to the desktop
ladder (a screen on 5901/6901), never the shell-only base ladder. Red on
main: the sheet and CLI hard-code `--base` and the resolver defaults
`kind ?? "base"`.

* Cloud: a desktop with a VNC screen is the default machine kind

Fixes the defaults half of #12239. Every create path that does not name a
kind now gets a machine with a screen, and shell-only is an explicit
choice:

- New Machine sheet: a Kind picker (Desktop | Base) with Desktop
  preselected whenever the backend lists a desktop image; Base is never a
  silent default. A deployment with no desktop image opens on Base and
  says so under the picker. The Set Up Base sheet offers the same choice.
  `limits.imageKinds` feeds the picker instead of being dead data.
- CLI: bare `cmux vm new`, `vm base open`, and `vm base reset` send
  `kind: desktop`; `--base` / `--no-desktop` ask for shell-only. The stale
  "no image available yet" help and the "flip back to desktop-by-default"
  comment are gone; `VMMachineKind.defaultKind` / `cliFlag` are the one
  place the default and the flag spelling live.
- Backend: `resolveVmImage` defaults `kind` to desktop
  (`VM_IMAGE_DEFAULT_KIND`), so older clients and API callers that send no
  kind (`vm base open` from shipped builds) also get a screen. An existing
  Base keeps its image; the kind only matters on first provisioning.
- READMEs and the CLI contract describe the separate desktop and base
  ladders and the desktop default truthfully.

Localization: the new sheet copy (`machines.new.kind.desktopUnavailable`)
ships English and Japanese; the picker reuses the existing kind keys.

* test: preserve cloud workspace sequence after rename

* test: GET /api/vm/[id] must echo the machine kind and private address

Regression test for #12239: `cmux vm status` and `cmux vm open` read the
single-machine route, which omits `kind`, so the client infers a shell-only
machine from the snapshot id and never opens the desktop of a machine
created with the defaults. Red on main.

* cmux-tui: keep the automatic workspace sequence monotonic after a rename

The next automatic name was the highest existing `workspace-N` plus one,
so renaming the only workspace (`workspace-1` → `shell`) and creating
another produced a second `workspace-1`. The sequence now never restarts
below the number of workspaces that exist: `shell` + new → `workspace-2`.
Existing names, user renames included, are still never rewritten.

Ships to machines with the next devbox rebake (the promoted wsboot ladders
carry 65ac4c2); this only affects the rename-then-create edge.

XCUITest for #12239: opening New Cloud Machine… from the palette shows the
Kind picker on Desktop (a machine with a screen), the summary describes it,

closes the sheet. Screenshots are attached for both states.

* test+docs: the explicit-provider vm new asks for a desktop too; README points at the manifest

The fourth `vm.create` mock (explicit `--provider freestyle`) still pinned an
image id; it now asserts `kind: desktop` and no image, like the others. The
web README's "today's default" bullet named a long-demoted ladder; it now
points at the manifest, the only source of truth, instead of duplicating
snapshot ids that drift.

* web: GET /api/vm/[id] echoes kind, capabilities, and the private address

`cmux vm status` and the CLI's open path read the single-machine route,
which returned no `kind`, so a desktop machine created with the new

from an `sh-…` snapshot id) and `cmux vm open` never opened its screen.
The route now returns the same machine shape `GET /api/vm` lists.

* cmux-tui: read the workspace id from state in the rename-sequence test

`Surface` exposes no workspace id; take it from the mux state like the
neighbouring sequence test does.

* test(ui): assert the New Machine kind through the summary text and segment values

XCUIElement.isSelected is not set on a segmented control's segments; the
selection is the segment's accessibility value, and the user-visible
summary under the picker is what proves which kind is selected.

`testVMSSHAliasUsesCmuxRemoteWhenProviderSSHIsUnmanaged` expects `cmux vm ssh`
to fall back to cmux-remote when provider SSH is unmanaged. Three parts of its
mock no longer match what the app sends or what the CLI asks for:

- The CLI falls back when the error's `data.backend_code` is
  `vm_attach_transport_unsupported`, and the app sends that code inside `data`
  under a `vm_error` code. The mock put the provider code at the top level with
  no `data`, so the CLI never fell back.
- Since manaflow-ai#12042, the CLI only dials a machine it has not opened before when
  `vm.cmux_remote_info` reports `trusted_carrier: true`. The mock left that out,
  so the CLI stopped with "The Cloud machine is still preparing remote access".
- Since manaflow-ai#12227, the CLI reads `surface.catalog` before choosing between
  projecting an existing terminal and opening a new one. The mock did not answer
  it. The mock now reports a connected machine with no remote workspaces, which
  keeps the test on the new-terminal path it was written for, and the expected
  request sequence includes the catalog request.

After the first mismatch the test read `bindCommands[0]` from an empty list and
crashed the test host. Send the app's response shapes, and fail instead of
crashing if the bind requests are missing.

`testVMResizeIsNoLongerAVerb` came in when `vm resize` was removed. manaflow-ai#12442
restored the verb on purpose and covers it in `tests/test_cli_vm_resize.py`,
so this test now fails by design. Remove it.
