Regression coverage for #14771. Devices (raw value `computers`) must be a visible sidebar leaf after Mobile, own a detail slot, appear in the empty-query section list, and win search for the names people use for the Cloud sidebar's My Devices feature. Every legacy navigation target and anchor must land on the Devices section rather than Mobile. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

#14332 folded the Computers section into Mobile and made `computers` a hidden alias of it, so Remote & Devices listed only Mobile and Cloud and `cmux settings open computers`, saved targets and searches for my devices or discovery all opened Mobile. Devices is a sidebar section again, between Mobile and Cloud, keeping the persisted `computers` raw value. Legacy `setting:computers:pair` and `setting:mobile:computers` anchors resolve to its header through one shared resolver. The My Devices switches are inline rows that write the same DevicesPreferencesModel as the Cloud sidebar menu, with curated search entries for each, and Mobile goes back to iPhone pairing only. While Cloud Machines is off the section now says why, and both switches and Refresh are disabled, instead of prompting to sign in or turn on discovery with switches that do nothing. HiveComputersService publishes the reason and republishes it on flag, beta toggle and managed-policy changes. User-facing paths that pointed at Computers now name Settings › Devices, and the section's strings are localized in all nine required locales. Closes #14771 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
HiveComputersService now reads ManagedDevicePolicy for the Devices unavailable reason and its change observer, but the file did not import CmuxSettings, so the app target failed to compile. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Remote & Devices should read Mobile, Cloud, Devices, Networking. The package tests pin the taxonomy, the section enum order and the detail stack to that order, and the UI test drives the sidebar, the Devices page, the Mobile page, Settings search and `cmux settings open computers` against it. These fail until the sections are reordered. Refs #14771 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Remote & Devices now reads Mobile, Cloud, Devices, Networking. Devices backs the Cloud sidebar's My Devices, so it sits under Cloud rather than between Mobile and Cloud. The taxonomy, the section enum (which orders search ties), the detail stack's display order and its slots all move together. Closes #14771 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
SettingsNavigationTarget listed Devices before Cloud, so the legacy search index broke score ties in the old order. Match SettingsSectionID and the Remote & Devices taxonomy: Mobile, Cloud, Devices. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Writing the override into the fixed com.cmuxterm.app.debug suite missed a tagged bundle's defaults and touched the developer's untagged debug app. A plist-typed <true/> argument reaches the flag reader in every bundle and leaves no state behind. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
SettingsComputersBehaviorUITests.swift had no PBXBuildFile, file reference, group entry or Sources phase entry, so the UI test bundle never compiled it. A test-e2e dispatch filtered to cmuxUITests/SettingsComputersBehaviorUITests built, executed 0 tests, and the selected-test guard rejected the run. The file was wired when it was added in 4141fb4 and lost later in a merge. This restores the same four entries with the original object IDs.

Resolves the conflicts with main's one-pane-at-a-time Settings (#12993) and natural-top pane placement (#14950). Devices stays its own section, so the placement and restore paths map section anchors by identity instead of folding computers into Mobile, and legacy Devices anchors still open the Devices pane at its top. The Devices UI test now checks the Mobile page and the landed Devices page as single panes, and the pbxproj keeps main's generated wiring for SettingsComputersBehaviorUITests.

…oxed runner Settings UI tests looked the window up by its "Settings" title with a 6 s wait. Progressive mounting makes the first open slower than that on CI, so every test failed at "Settings window did not open". Take #15061's fix: find the window by its `cmux.settings` identifier and wait 10 s. The `cmux settings open computers` test uses the same identifier. That test's CLI inherits the runner sandbox, which denied its /tmp socket (errno 1). Put the socket in the runner's temp directory, as HookPromptLengthUITests does.

The first run that reached the assertions (glaeda, run 36362237361) passed two Devices tests and failed three, all in the test's element lookups: - The one-pane window repeats the selected section's name as its toolbar title, just above the detail scroll view. The header lookup took that title, so a correctly shown Devices or Mobile page read as outside the viewport. Look only inside the detail scroll view. - The search result list keeps the browse list's scroll offset, so the top "Devices" result sat above the visible rows and the click computed from its frame hit the menu bar. Click the row element, which XCUITest scrolls into view, and check it is the section result. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Main's #14772 gave Devices its own Settings section and moved the "Make this Mac discoverable" switch there, so the error's path to Settings › Computers no longer matched a section.

…ed agents (#14420) * test: distinguish Mac discoverability from discovery and identity failures * fix: require Mac discovery consent and report confirmed opt-out * test: cover Mac terminal grid updates after coalesced render ticks * fix: propagate Mac terminal grid changes without reopening mirrors * fix: make oversized Mac mirrors locally scrollable * fix: adopt device split reservations in their target pane * fix: include prose wake driver in macOS target * test: bound distinct device grid queue events * fix: harden device layout and grid delivery * fix: avoid retaining device mirror attachment * fix: compile device pane reconciliation * fix: use native pane identifiers in device projection * fix: expose reservation identity binding * fix: use reservation parameter in device materialization * fix: bound grid queue ownership and pending layout admission * fix: avoid namespace policy lint violation * Hand a reserved pane's input to an adopting device mirror safely A device mirror that adopts an optimistic reserved pane now takes over the pane's input relay with its own byte router, which fixes the macOS compile error where the provider passed a DeviceTerminalInputRouter to a relay that only accepted the Cloud router. - Reserved panes for devices install no named-key resolver. The device router sends bytes only, so a resolver would drop Enter, arrows and Tab. - The relay is handed over only when adoption succeeded, and only on an attach that is not immediately replaced by a queued replay, so input typed before the terminal attached is delivered in order and not dropped mid-handoff. - Input typed while the source Mac is unreachable is discarded on detach and never replays after reconnecting, matching panes the router created itself. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Import Bonsplit where the layout projection test names a pane Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Test that a replacement grid overflow reaches the drain A Mac grid replacement larger than the byte budget returns overflow without recording it, so the fan-out path never closes the connection. A running drain can also finish over a pending overflow and strand it. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Close the connection on every event queue overflow The queue's pending overflow flag is the one signal a drain uses to close the connection. Every overflow result now records it and claims the drain through one helper, a running drain checks it on each pass, and neither finishDrain nor claimDrain lets an unconsumed overflow go unobserved. The unrecorded .overflow constant is removed so no branch can skip the flag. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Test that two device splits adopt their own reserved panes Two outstanding device splits in one remote workspace must each adopt the reservation bound to the terminal it created, and a terminal that no request created must never take an unbound reservation's pane or queued input. The existing split test now binds its reservation through the create receipt and uses a UUID remote workspace, which the layout coordinator requires. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Adopt a device split's pane only for the terminal bound to it Device layout reconciliation took the first pending reservation in the remote workspace and adopted it for any new terminal whose id matched the reservation's source placement. Before its create receipt binds, that placement names the split source, so a second outstanding split, or a terminal no request created, could land in the wrong pane and receive another terminal's queued input. Invariant: a reservation's pane is used only for the terminal its create receipt bound (`boundResourceID`). `cloudPendingCreations` is the only request-to-terminal record, so reconciliation looks up the reservation per terminal and uses the same one for the destination pane and the adoption. Reconciliation is suspended while a device create is in flight, so a layout the host pushes before the receipt returns waits until the reservation is bound. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Test that a growing grid replacement sheds droppable events first A replacement Mac grid that outgrows the byte budget closes the connection today even when queued terminal bytes could be shed to make room. Normal admission sheds droppable events before it overflows. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Admit a replacement grid through normal admission A queued Mac grid is superseded by the next one for the same terminal, so drop the old entry and admit the new frame the same way as any other grid frame. Growing replacements now shed droppable events before an overflow closes the connection. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Test that a queue overflow closes during lane negotiation A drain that finishes a send while an independent-lane probe is parked returns before it consumes a pending overflow, so the connection stays open until the probe resolves. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Close an overflowed connection before yielding to lane negotiation The drain now consumes a pending overflow before it checks for lane negotiation, so a parked probe cannot delay the close. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Make the unbound device reservation tests deterministic With one unbound reservation, a terminal no request created must not take its pane. The adoption guard that protects the pane's queued input is now tested directly on Workspace, since the placement test provider never touches pending creations or the input relay. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Test that a subscription negotiated across an overflow close does not leak A queue overflow closes the connection while a second stream's lane negotiation is parked. Close releases the connection's subscriptions, so the subscribe that resumes after it must not register a new topic count that nothing will ever release. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Drop a subscription whose connection closed during lane negotiation The subscribe handler awaits the independent lane probe before it registers the stream. A queue overflow can close the connection while that probe is parked; close releases every subscription it knows about, so a registration that lands afterwards leaks a process-wide topic count and keeps the host emitting for a client that is gone. Re-check after the negotiation and fail the request instead. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Materialize device terminals in the layout tests the way the device provider does The split fixture created terminals through newTerminalSurface, which routes to the machine instead of the viewer once the pane's selected tab is Cloud-owned. A terminal bound to a reservation now takes the reserved pane, and any other terminal gets a new manual-mirror pane at its destination, as materializeManualMirrorTerminal does in production. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Test that a failed device reservation does not block layout updates A failed create keeps its reservation and pane for Reconnect. Layout reconciliation admits that panel through cloudPendingCreations, so a later terminal still projects into its own pane and the reserved pane stays put. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Test that a pending or failed device reservation does not block layout sync A reserved pane has no terminal on the owning Mac yet. The workspace must still apply the owner's arrangement around it, send local gestures without it, and close a mirrored pane's terminal on the owner. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Keep a pending or failed device reservation from blocking layout sync A reserved pane has no terminal on the owning Mac until its create binds. Applying the owner's layout now grafts reserved panes back where this Mac showed them, local gestures are sent without them, and closing a mirrored pane no longer mistakes a reservation for an unrelated local pane. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Test that closing a connection ends an event drain parked in a write Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Keep the event drain's task handle so closing the connection cancels it Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Place stranded reserved panels in local order and bind every lent reservation in layout tests Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Test that a reserved pane keeps input typed before its first attach sticks A reserved Cloud pane's first attach can fail while the Mac is still reachable-but-not-ready. Input typed during that attach transition belongs to the same remote surface and must be delivered in order once an attach sticks. Input typed after an attached Mac disconnects is still dropped, and stopping the mirror session (owner change) must discard queued bytes so a replacement never inherits them. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Keep a reserved pane's early input until an attach sticks The mirror session discarded the adopted relay's queue on every transition to .detached, including a failed first attach, so input typed while the reserved pane was still attaching to its remote surface was dropped. The relay now keeps that input for the same remote surface and delivers it in order when an attach first sticks. After the handoff the device router still drops input typed while detached, and stopping the session discards anything held so a replacement owner never inherits it. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Test that a lane that stays backlogged keeps its order storage bounded A lane whose drain keeps pace without ever emptying leaves every consumed ID in front of the order's head, where compaction never looks. After 10,000 enqueue/dequeue pairs the lane holds 10,045 IDs for 10 queued events. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Count consumed IDs when compacting a lane's event order Compaction compared only the IDs after the head against the live count, so a lane whose drain kept pace without emptying never freed the IDs it had consumed. Counting the whole array rebuilds the order once dead or consumed IDs outnumber the live ones, which keeps the storage bounded and every operation amortized O(1). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Test that a reserved pane drops early input when its Mac link drops Input typed into a reserved pane is held across replay failures while the link to the Mac stays up. Once the link drops before an attach sticks, the Mac may come back with a new shell under the same surface ID, so the held input must be dropped instead of replayed into it. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Drop a reserved pane's held input when its Mac link drops A reserved pane holds what was typed until an attach sticks, so a replay that fails on a live link loses nothing. When the link itself drops first, a restarted Mac can restore a terminal under the same surface ID with a new shell, so the held input is discarded instead of replayed into it. The next attach that sticks resumes forwarding. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Wait on the connection's close signal in the lane overflow test The test polled the transport's close count for a fixed number of yields, which can finish before a loaded runner's drain closes the connection. It now awaits the connection's onClose, which runs after the transport closes, under a one-minute test limit. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Test that a rejected grid replacement keeps the queued grid A replacement Mac grid that cannot fit overflows the connection. Until the close runs, the queue should still hold the last admitted grid rather than neither snapshot. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Keep a queued Mac grid until its replacement is admitted The replacement used to drop the queued grid before checking whether the new frame fit, so an overflowing replacement left neither snapshot queued while the connection closed. The old grid's room now counts toward the replacement, and the old entry leaves only once the new frame is admitted. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Expect the beta nightly floor in the team What's New copy test #12389 gave iOS 1.0.4 beta builds the 0.64.22 nightly floor, and MobileMacCompatPolicyTests asserts it, but this copy test still expected no nightly version. It only runs when the iOS simulator lane is routed, so it failed on this branch's first full simulator run. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Own event drains in the connection actor Every drain now starts through one actor-isolated method that checks isClosed and records the task handle in the same turn, so close() can cancel every drain it admitted and a claim that arrives after close() is released instead of started. This replaces the unfair lock that guarded the handles from the nonisolated fan-out path; the fan-out hops onto the actor once per claimed drain, not once per event. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Move reserved-panel layout grafting into CmuxCore Removing and restoring reserved panels in a Mac device workspace layout is pure tree logic, so it now lives on DeviceWorkspaceLayoutNode in CmuxCore with package tests. Grafting indexes both trees once and wraps a restored split around the lowest common ancestor of the panes it divided, which is linear in the layout size instead of re-searching the tree per restored panel. A randomized differential test checks it against the previous per-panel insertion. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * State the unique panel ID precondition on layout grafting Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Read event order bookkeeping from the test target The bounded-order test read a production accessor that existed only for it. The arrival orders are now internal-read, and the test sums them itself through @testable import. The large graft test no longer asserts a wall-clock bound, which could fail on a loaded runner; it checks the restored layout at 40,000 panels. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Drop main actor isolation from the grid publisher value The publisher is a plain value that its owner mutates in place; its closures run synchronously in the caller's context. Nothing about it needs the main actor. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Index bound reservations once per device layout pass Reconcile looked up each missing terminal's reservation by scanning every pending creation, and filtered stale projections with a linear contains over the wanted list. Build a key index of bound reservations and a set of wanted terminals once per pass instead. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Test that a retried device create keeps the pane the layout already mirrored A device split whose first create receipt is lost leaves its reservation unbound, so the owner's layout mirrors the new terminal in a pane of its own. Reconnect replays the create and gets the same terminal back. The test expects that terminal to keep its single pane and later layouts to keep applying. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Reuse the mirrored pane when a device create returns a terminal already shown A device layout can project the new terminal before its receipt binds the reservation, after a lost receipt or when the layout event beats the create response. The create's projection then made a second pane for that terminal and every later layout for the workspace failed with an unmapped surface. The reserved pane now gives way to the existing projection instead. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Test that a reserved pane giving way to its mirror hands over focus When a retried device create finds its terminal already mirrored in another pane, the reserved pane closes. If the user was in that pane (they pressed Reconnect there), focus should land on the pane showing the new terminal rather than on whichever neighbor the split tree picks. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Hand focus to the mirrored pane when a reserved pane gives way A device create that finds its terminal already mirrored closes the reserved pane. If that pane had focus, the split tree picked a neighbor, which could be an unrelated terminal. Focus now moves to the pane showing the terminal the user asked for. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Reuse a mirrored projection only while its pane is still open The catalog matches projections by resource, workspace and tab without checking the panel. A create that found a projection whose pane had already closed would finish on a pane that no longer exists and close the reserved one. It now projects into the reserved pane as before. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Test that a device link delivers grid events to its surface's mirror Terminal envelopes now reach their mirror sessions through one DeviceLinkTerminalEvents.receive(_:) call, so the link has no second list of terminal topics to keep in step with the decoder. The new test feeds terminal.updated and device.terminal.grid envelopes through that path and checks that each topic is subscribed. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Find every restored split's layout anchor in one pass Each restored split walked the owner tree from both of its terminals to find their lowest common ancestor, so a chain-shaped layout with many reserved splits cost the tree depth once per split. Grafting 32,000 nested reserved splits around a 32,000-pane chain took 27.5 s. A wrap only inserts a split above a target node, beside a branch with no target panel, so the anchor from the unwrapped tree stays correct after every wrap. Tarjan's offline algorithm finds all anchors in one pass over the owner tree before grafting. The same layout now grafts in 0.25 s, and 8,000 splits in 0.06 s instead of 1.7 s. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Test grid delivery through the device link's own event routing The previous test fed the envelope to the terminal fan-out directly, so a topic case added ahead of the default branch in DeviceLink.handle could swallow terminal.updated or device.terminal.grid without failing it. The test now builds a DeviceLink and hands the envelope to handle, the method the event consumer calls for every host event. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Remove catalog keys the main merge duplicated The merge of main 83270f1 ran git's line merge on Localizable.xcstrings because this clone had no xcstrings merge driver registered. The branch had moved the three cloud.link.sshPreflight entries, so the line merge kept both copies. This rebuilds the catalog with scripts/merge-xcstrings.py from main's text: it matches main except for devices.link.error.notDiscoverable. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Keep main's key order in the string catalog after the merge The merge's key-level union kept every string but moved keys out of main's order, a 1,451-line diff. The catalog is rebuilt from main's text with merge-xcstrings.py, so it differs from main only by the branch's devices.link.error.notDiscoverable key. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Test that a remote replay resumes a hibernated agent terminal Another Mac or the phone attaches to a terminal through mobile.terminal.replay. When Agent Hibernation had torn the terminal's runtime down, the replay came back empty and no output followed, so the viewer showed a blank pane with no disconnect overlay. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Resume a hibernated agent when a remote viewer attaches A remote Mac or the phone attaching to a terminal is visiting it, the same as selecting its tab on this Mac. mobile.terminal.replay now wakes a hibernated agent before building the replay. Before, the replay of a torn-down runtime was empty, no output followed, and the viewer showed a blank pane with no disconnect overlay. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Wake a hibernated agent only for a valid, bound replay A replay with an invalid viewport report no longer wakes the agent before it's rejected. Like explicit input, the resume goes through the panel only when the resolved surface is still the panel's own, so a respawn's outgoing panel can't be resumed. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Name Settings › Devices in the not-discoverable error Main's #14772 gave Devices its own Settings section and moved the "Make this Mac discoverable" switch there, so the error's path to Settings › Computers no longer matched a section. The English text and all 20 translations now name the Devices section with the same words main uses for its other Devices paths.

Closes #14771
Settings › Remote & Devices has a Devices section again, directly below Cloud: the group reads Mobile, Cloud, Devices, Networking. It's the settings home of the Cloud sidebar's My Devices. It holds the two switches, Make this Mac discoverable and Discover other Macs, which write the same preferences as the sidebar's My Devices menu. Below them are Your Macs with a Refresh button, the account's other Macs, and their pair, hide and open actions. Mobile is back to iPhone pairing only.
What was wrong
#14332 folded the Computers section into Mobile and turned
computersinto a hidden alias of it. As a result:cmux settings open computers, saved navigation targets and search for "computers", "my devices" or "discovery" all opened Mobile.A second bug showed up once the section was visible again. With Cloud Machines off (the Release default until the beta opt-in and the remote flag are both on), the section still showed the sign-in or discovery prompt. Its switches read on but did nothing, because
DevicesFeature.isAvailable()is false and nothing runs.Reproduce on
main:cmux settings open computers: Mobile opens, and Devices shows as a card at the bottom.Design
Identity:
SettingsSectionID.computerskeeps its raw value, titled "Devices". The raw value is persisted inAppStorage, in navigation targets and insetting:computers:*anchors, and the CLI already accepts bothcomputersanddevicesfor it. Renaming the case would mean a migration plus a compatibility alias for every old value, and it would change nothing a user sees. Keeping the raw value makes every existing link resolve with no migration.Old anchors saved while Devices lived under Mobile still work. Both

The resolver lives in one place,SettingsSectionID.navigationDestination, and every entrypoint uses it:SettingsWindowPresenter,The switches are inline rows, not the compact menu from 0b3a5ee. On a settings page, a switch with a subtitle is the standard control, and search can scroll straight to a row. The two new curated search entries,
setting:computers:discoveryandsetting:computers:incoming-access, need rows to land on. The Cloud sidebar keeps its compactComputerAccessMenuItemsmenu. Both surfaces write throughDevicesPreferencesModel, so a change in one shows up in the other.What the section shows, in priority order:
