[#12575] Compact Cloud tree spacing, VM pins, and optimistic workspace changes

The Cloud sidebar now keeps the main tree presentation while tightening the shared geometry so folders, terminals, resources, and section rows read as one filesystem outline. The existing explicit VM pinning and optimistic workspace lifecycle work remains in the same PR.

Compact tree geometry

  • Compact rows are 22 pt and single-line machine rows use the same height.
  • AppKit disclosure controls use one 12 pt square hit target and a 1 pt content gap; the drawn chevron has a square 5 pt footprint and the same stroke/ink bounds when collapsed or expanded.
  • Leaf icons use the shared 16 pt slot with a 4 pt icon-to-title gap. Pin and unread decoration share a compact 2 pt leading cluster, and unread state badges the icon without moving the title.
  • The outline and SwiftUI content read the same CloudTreeRowGrid values, so narrow/wide sidebars and 100/150% magnification keep carets, icons, labels, and trailing content aligned.

Existing Cloud behavior retained

  • Explicit VM pin persistence/order, optimistic workspace deletion/rollback/fencing, rename projection, refresh/reconnect, accessibility labels, localization, and local-machine behavior remain covered by the existing implementation.
  • The current main branch's default-machine designation is intentionally retained for this spacing pass, per the latest request to match main except for compact alignment.

Verification

  • Focused hosted acceptance: run 35422506399, Tart macOS runner, cmuxTests/CloudSidebarAcceptanceTests, 4 tests passed. It rendered the production outline at 220/360 pt, 100/150% magnification, collapsed/expanded, pinned/unpinned, selected/hovered, and optimistic delete states.
  • Final tagged app build: run 35423239518, Tart macOS runner, final pushed tree 68c5916098. The app is installed and launched with the direct GCP backend.
  • Tagged app opener: http://127.0.0.1:17320/issue-12575-cloud-sidebar-alignment
  • Authenticated dogfood account: austin@manaflow.ai; Cloud beta gate and DEBUG Cloud Machines override are both enabled for the tagged bundle only. vm ls --json returns the running GCP-backed VM.
  • Static checks: git diff --check, Swift file-length budgets, localization parity (9 locales), pbxproj normalization, test wiring, and Cloud CLI skill coverage pass.

The PR remains unmerged pending the required GitHub checks and Austin's dogfood approval.

📝 Walkthrough

Walkthrough

The change removes default-machine routing and adds explicit machine selection. It adds scoped machine pinning, shared sidebar geometry, selection-aware creation, failure handling, and related tests, localization, documentation, and project wiring.

Changes

Cloud workspace targeting

Layer / File(s) Summary
Selection and coordinator contracts
Packages/macOS/CmuxCloudMachines/Sources/CmuxCloudMachines/*
Workspace creation accepts an explicit machine ID, validates the loaded fleet, supports target-window creation, and coalesces duplicate requests.
Selection-aware application flow
Sources/AppDelegate*, Sources/cmuxApp*, Sources/Workspace.swift
New Workspace actions capture tree selection and route local or Cloud creation without a default machine. Failures provide retry and cancel actions.

Machine pinning and sidebar layout

Layer / File(s) Summary
Scoped machine pinning
Packages/macOS/CmuxCloudMachines/Sources/CmuxCloudMachines/CloudMachinePinStore*, Sources/Cloud/MachinesPanelView*
Machine pins persist by account and team. Pinned machines remain first in stable order. The default-machine store and preference are removed.
Shared row geometry
Sources/Cloud/CloudTreeRow*, Sources/Cloud/*RowContent.swift, Sources/Cloud/Sidebar/*
Rows use shared magnification-aware spacing, disclosure, icon, status, and trailing-action slots. Pin indicators do not shift peer row content.
Validation and integration
cmuxTests/*, Packages/macOS/CmuxCloudMachines/Tests/*, Resources/Localizable.xcstrings, Packages/macOS/CmuxCloudMachines/README.md, cmux.xcodeproj/project.pbxproj
Tests cover explicit creation, pin persistence and ordering, selection resolution, row geometry, shortcut migration, capability reuse, localization, documentation, and project registration.

Full details: Cmux Algorithmic Complexity

Explanation

The new pin projection adds an unbounded collection rebuild to the SwiftUI render path. MachinesPanelView.machinesList is evaluated from body and passes viewModel.sidebarMachines at Sources/Cloud/MachinesPanelView.swift:447. sidebarMachines at Sources/Cloud/MachinesPanelViewModel+MachinePins.swift:10-16 merges the fleet and catalog, maps every machine, and orders the result on each render. Ordering builds dictionaries and performs multiple full scans, including the two filters at CloudMachinePinStore.swift:77-85. The pin action rescans sidebarMachines twice at MachinesPanelViewModel+MachinePins.swift:20-21. This violates the rule for rebuilding, sorting, or filtering scalable UI collections on every event. The expected scale is about 1,000 VMs, and no UI cache or benchmark-backed bound is provided.

Resolution

Cache the ordered, pin-stamped sidebar machine snapshot in MachinesPanelViewModel or an equivalent store. Recompute it only when the fleet, catalog, account/team scope, or pin state changes, then pass that cached snapshot to CloudTreeOutlineView. In setMachinePinned, read the cached snapshot once instead of calling sidebarMachines repeatedly. Use a single-pass partition or an already ordered representation in CloudMachinePinStore.orderedMachineIDs to avoid the two full filters. Add a benchmark or measurement for roughly 1,000 VMs and refresh-event/render performance.

Full details: Cmux Swift Concurrency

Explanation

The diff adds an internal failure callback to CloudWorkspaceOperationController.start(key:_:): the new onFailure: @escaping @mainactor (Error) -> Void parameter is invoked from the stored async task's catch, and performNewCloudWorkspaceOnMachineAction uses it to present Retry/Cancel. This is a new callback-based async result path between cmux-owned code even though the operation already uses async throws. No new background dispatch queue or Combine state was added. The onReceipt callback was moved from the base file, the alert completion handler is an AppKit boundary, and the test task exercises controlled concurrency.

Resolution

Remove the onFailure callback API. Keep the operation as async throws and handle the error in the caller's async operation closure, or expose an awaitable task result that the caller can catch. Preserve the controller's existing stored-task cancellation and keyed-operation lifecycle. Keep the AppKit alert completion handler only at the AppKit boundary.

Full details: Cmux Architecture Rethink

Explanation

The PR adds a second owner for per-machine in-flight creation. CloudWorkspaceCoordinator now tracks creatingMachineIDs and drops requests in createOnMachine, while the pre-existing CloudWorkspaceOperationController.keyedTasks already coalesces the same app requests by new-cloud-workspace.machine:<id>. This split creates a cancellation race: cancelAll() removes the controller task and permits a replacement, but the cancelled coordinator call can still retain the machine ID until its async create closure returns. The replacement can then pass fleet validation and be dropped by creatingMachineIDs. This is a changed-code match for the rule's new mutable state with duplicate ownership and leaves bad lifecycle state representable.

Resolution

Use one owner for per-machine in-flight creation. For the current app path, make CloudWorkspaceOperationController.keyedTasks authoritative, remove creatingMachineIDs and the coordinator-level coalescing test, and require every production Cloud workspace creation entrypoint to use the keyed controller. Add a cancellation/re-enable replacement test that proves a new request starts after cancelAll() even when the old create closure has not returned. If the coordinator must own this invariant instead, remove the per-machine keyed controller path and expose the coordinator-owned request lifecycle to all callers; do not retain both guards.

66-82: 🎯 Functional Correctness | 🔴 Critical | ⚡ Quick win

Fail closed for .unavailable in performNewCloudWorkspaceFromSelectionAction.

This function only matches .cloud on newWorkspaceMachineContext(for: context).target. When the Machines sidebar owns focus and the tree selection is .pending, the target resolves to .unavailable, but the if does not match it. Execution falls through to performNewCloudWorkspaceAction, the machine-provisioning path, and can create an unintended Cloud machine.

This is the same defect already raised for this function in an earlier review round. The fix was applied to the sibling performNewWorkspaceSelectionAwareAction (lines 17-29) but not here. Apply the same switch pattern so .unavailable fails closed instead of falling back to provisioning.

🐛 Proposed fix
-        let context = preferredWindow.flatMap { contextForMainWindow($0) }
-            ?? preferredMainWindowContextForWorkspaceCreation(event: nil, debugSource: debugSource)

-            return performNewCloudWorkspaceOnMachineAction(
-                machineID: machineID,

🟠 Major · Synchronize the AppKit selection when the structured selection… · CloudTreeOutlineView.swift:65

Sources/Cloud/CloudTreeOutlineView.swift:65
🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Synchronize the AppKit selection when the structured selection changes.

MachinesPanelView supplies CloudTreeSelection from the window-owned AppDelegate context. When that value changes, updateNSView assigns it, but Coordinator.apply(nodes:) returns if the node signatures are unchanged. NSOutlineView.selectedRow then remains on the old node, and openSelection() can operate on that stale row.

Use one selection update method. Treat CloudTreeSelection as the authoritative state and project it into NSOutlineView under withProgrammaticUpdate. Clear the AppKit selection when selection.nodeID is missing or unavailable.

Proposed first migration cut
-        context.coordinator.selection = selection; context.coordinator.onSelectionChange = onSelectionChange
+        context.coordinator.onSelectionChange = onSelectionChange
+        context.coordinator.apply(selection: selection)

- Around line 391-475: Update the DEBUG-only test declarations, including
testCommandYCoalescesOneCreateAndOpenIntentUntilItFinishes and
testReboundKeyRoutesAndOldKeyDoesNot, so Release builds exclude them or
explicitly skip without calling Issue.record. Preserve their existing DEBUG test
behavior while preventing non-DEBUG runs from reporting failures for an
unavailable seam.

In
`@Packages/macOS/CmuxCloudMachines/Sources/CmuxCloudMachines/CloudMachinePinStore.swift`:
- Around line 131-133: Update setPinned so each machine exists in current.order,
and a false-to-true transition moves machineID to index zero before preserving
the remaining order; unpinning should only remove it from current.pinned. Adjust
the multi-pin test to verify pinning c then a results in a before c.

In `@Sources/AppDelegate`+NewCloudWorkspace.swift:
- Around line 167-174: Update the alert construction around the retryIfChosen
closure to distinguish targetWindowUnavailable from retryable errors: present
only the Cancel/dismissal action when the target window is unavailable, and add
the Retry action only for other errors. Ensure the retry path does not resubmit
the same captured windowID when that window has closed.

In `@Sources/Cloud/CloudTreeLocalMachineRowContent.swift`:
- Line 26: Wrap the entire style.machineRowLayout switch in a single
CloudTreeMachineBand in the body of CloudTreeLocalMachineRowContent, so both
single-line and two-line layouts receive the band decoration. Preserve the
two-line layout’s vertical padding, trailing spacing, content alignment, and
shared accessibility modifiers.

In `@Sources/cmuxApp`+CloudWorkspace.swift:
- Around line 26-35: Move pending receipt lifecycle ownership into
CloudWorkspaceCoordinator and scope each receipt to its single creation
operation. Ensure Retry reuses the receipt for that operation, while Cancel,
task cancellation or thrown failure, and successful completion all clear the
receipt before another creation for the same machine can use it.

P3: The rewritten suite drops all coverage of the availability-gating paths in `createOnMachine`, even though the removed parameterized test `unavailableActionsDoNotCreate(accessEndsDuringList:)` explicitly covered them. Every new test passes `allowsOperation: { true }`, so the two `guard isAvailable else { return nil }` branches in CloudWorkspaceCoordinator.swift (lines 41 and 47, both the pre-list and post-list recheck) are never exercised at the unit level.

<file name="cmuxTests/CloudWorkspaceDeleteOptimismTests.swift">

<violation number="1" location="cmuxTests/CloudWorkspaceDeleteOptimismTests.swift:16">
P2: This test cannot pass against the current `deleteWorkspaceAndTerminals` implementation. `provider.refresh()` is invoked at the very start of `CloudTreeNodeActions.deleteWorkspaceAndTerminals` (before any deletion), so the `onRefresh` closure runs with the terminal still registered and the machine still reporting `remoteWorkspaces: [workspace]`: both `catalog.snapshot.machines.first?.remoteWorkspaces?.isEmpty == true` and `catalog.snapshot.resources.isEmpty` fail there. The closure is also internally contradictory: `catalog.snapshot.resources` is a value copy of `catalog.resources.values` (see `var snapshot` in `Sources/Surfaces/SurfaceCatalog.swift`), so `catalog.resources[provider.terminal.id] != nil` and `catalog.snapshot.resources.isEmpty` can never both be true. Nothing in the delete path removes the terminal from the catalog (the test provider's `closeTerminal` only appends to `closedTerminals`), so the final `#expect(catalog.snapshot.resources.isEmpty)` fails as well. Either implement optimistic catalog deletion in `deleteWorkspaceAndTerminals` before the refresh, or rewrite the assertions to match the actual contract: the catalog retains resources until the provider's next `replaceResources` publishes the deleted state.</violation>

<violation number="1" location="Sources/Cloud/CloudTreeMachineBand.swift:21">
P3: The `.padding(.leading, -6)` on the band's background is clipped away in the only render path: `CloudTreeCellView.configure` wraps the row content in `.frame(...).clipped()`, and the cell's leading edge is the clip origin, so the 6pt leftward extension never draws. The visible band keeps starting exactly at the content-area leading edge, and the icon column now sits flush against the band's left border instead of the intended 6pt inset. If the band is supposed to extend behind the caret gap, the extension must be drawn at a level the cell clip does not cut (or the clip relaxed); otherwise remove the `-6`/`-2` padding modifiers as inactive decoration.</violation>

P2: The assertion bound is scaled by `GlobalFontMagnification.storedPercent` (read from `UserDefaults.standard`), while the rendered dot's position follows the SwiftUI environment magnification (`cmuxGlobalFontMagnificationPercent`) from `CloudSidebarRowDecoration`. In this test the cell is rehosted in a bare `NSWindow`/`NSHostingView`, so the render uses the environment default, which is not necessarily the persisted percent. On a machine with a non-100% saved magnification the comparison mixes two magnifications: below ~80% stored the test fails spuriously (dot renders at 12.5 scaled-ish points vs. a bound of `16 × m`), and above 100% it stays green even if the dot has spilled into the icon column. Make the test self-contained by pinning the magnification the fixture renders with (e.g., seed/restore the stored percent in the fixture, or resolve `CloudTreeRowLayout` with the magnification the row actually renders at).</violation>

<file name="cmuxTests/NewCloudWorkspaceShortcutTests.swift">

<violation number="1" location="cmuxTests/NewCloudWorkspaceShortcutTests.swift:17">
P2: `.serialized` only serializes tests within this suite; Swift Testing still runs other suites in the same bundle in parallel. These tests mutate process-wide state that other Cloud suites can concurrently touch: `UserDefaults.standard` keys (`cloudOptInKey`, `BrowserAvailabilitySettings.disabledKey`), `CmuxFeatureFlags.shared` overrides for `cloud-machines-enabled-release`, and `AppDelegate.shared` shortcut routing state. A concurrent suite toggling the same flags or defaults can make the `#expect(... CloudMachinesFeature.isEnabled == enabled)` and gating assertions in this file flaky. Mitigate by reading/writing the test-only defaults through a suite-scoped `UserDefaults(suiteName:)` (as the deleted `CloudShortcutTests` suites did), and confirm no sibling suite shares the `CmxFeatureFlags` override keys, since flag overrides cannot be isolated per test bundle.</violation>

The catalog-only fallback on base main (9f29ddf, CloudTreeNodeBuilder.nodes) already builds the same MachineSnapshot with createdAt:nil and default free-access state. This PR factors that existing fallback into MachineSnapshotBuilder so pins cover catalog rows; it does not change its access policy. Server authorization remains authoritative. Treating unknown expiry as expired would change main’s product behavior beyond the current request.

A pin glyph wider than the scaled `statusSlot` would still pass every assertion here. Measure the glyph's right edge (or assert max glyph x ≤ `statusSlot + statusGap` scaled), or rename the test to describe what is actually asserted, e.g. "The status slot scales with the row text so the identity column stays fixed".</comment>

The earlier fixed status-column test was removed with the shared-grid rewrite. The current test retains main’s explicit leading-pin behavior; the new noEmptyAttentionGutter regression measures the actual rendered content edge and does not claim to measure pin glyph overflow.

The transform is intentionally not a no-op: snapshot now hides projections for a pending workspace delete. closeLocalPanes must enumerate authoritative projections so it still closes the real native panes once the backend confirms each terminal close. Before this PR, snapshot simply sorted the same projections set; it did not merge pendingRestoredProjections. Returning to the filtered snapshot here would skip every optimistically hidden pane.

…mistically

Reduces #12743 to what main needs on top of the current tree: no row-grid
alignment pass and no default-machine removal.

VM pins: `CloudMachinePinStore` (CmuxCloudMachines) persists explicit machine
pins and the stable first-seen fleet order per account/team scope. The Machines
panel stamps pin state onto immutable row snapshots, pinned machines sort first,
new machines append, and Pin/Unpin Machine leads the machine context menu in
every access state. Pins are independent of the Cmd+Y default machine.

Optimistic deletion: `CloudWorkspaceDeletionLedger` is catalog state, so every
sidebar and socket reader sees one tree. A delete hides the workspace and its
terminals synchronously, navigation into it is cancelled, a late projection
refresh cannot recreate its panes, success is fenced by the daemon cursor, and
failure rolls back without inventing live processes. The outline keeps the
hidden row's expansion and hands its selection to the machine until confirmed.

Optimistic renames: the catalog snapshot projects pending rename intents from
`CloudRenameCoordinator` (and accepted receipts from the machine observation)
onto workspace, tab, and terminal rows the moment they are admitted; local
workspace and pane titles follow the same intent through the existing
reconciliation, and a failed intent falls back to the accepted graph.

Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
Both fail identically on main: the App Store lane test still stamps
PRODUCT_BUNDLE_IDENTIFIER after #12935 moved archives to scoped bundle
settings and added the notification extension profile, and the Resources
section changed which nested rows the tree builder emits and persists.

…ovenance

The pending-name follow-through for local workspace and pane titles stamped
`.remote` provenance over agent (.auto) and user titles the moment an intent
was enqueued, which the rename reconciliation and checkpoint-restore suites
protect. Local titles keep main's exact rules and follow the accepted graph;
the catalog snapshot still projects pending intents so the sidebar and
socket readers show a rename immediately and roll back on failure.

Resolves the overlap with main's optimistic machine creation (#12919), the
stale-machine snapshot flag and presentation mapping (#12978, #12675):

- `SurfaceCatalogSnapshot` keeps both `pendingWorkspaceDeletions` and main's
  `staleMachineIDs`, with one decoder that tolerates either being absent.
- `authoritativeSnapshot` maps resources through `resourceForPresentation`
  and flags stale machines exactly as main's `snapshot` did; the projected
  `snapshot` layers deletion and rename intents on top.
- The Machines panel reads the catalog through the pin store's scope and
  reconciles the create coordinator's authoritative state in one pass; the
  tree receives `sidebarMachines` plus main's adopted operation ids.
- Main's cancellable/reconciling pending-create verbs land in the extracted
  `CloudTreeOutlineView+MachineMenu`.
- The project keeps main's file references for `SurfaceCatalogSnapshot.swift`.

Restores the outline's native disclosure control (the custom-drawn
`CloudTreeDisclosureButton` and its square hit target are gone) with the
16pt disclosure column and 2pt gap the compact rows were tuned against.
The compact row heights, icon gap, and the gutter-free row decoration stay
as they are; only the caret artwork and its column go back to what the
sidebar had before.

The compact layout test now asserts the native control, the fixed column
width across collapse, and drops the custom-artwork ink comparison.
