Cloud: make New Machine creation optimistic - #12919
Merged

Conversation
Three reproducible benchmarks for issue #12905, beside the existing smoke and stress scripts, plus a shared stats helper with unit tests: - bench-vm-startup.mjs: create -> attach -> warm attach -> exec -> pause -> resume-attach -> destroy against a deployed backend with a throwaway Pro user, capturing the create route's Server-Timing stages, optional concurrency and an in-guest model-plane edge readiness probe. - bench-freestyle-floor.ts: the provider floor with the SDK only: allocation, daemon process/listen, announce, exec/data/fs round trips, guest shell startup as the work user, pause/start/delete, and a concurrent burst. - bench-private-link.ts: the app's transport path headlessly: production driver create, attach bundle, WireGuard hub, cmux-tui remote connect --carrier, session snapshot, bash -l, prompt visible, reconnect. Every run creates, measures and deletes only its own VPC, tunnel and machines; existing machines are never read or modified. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
) Source-grounded report on where Cloud machine startup time goes, with the measured production baseline (14 days of server and client telemetry), the provider floor and transport measurements from the new benchmarks, a lower-bound budget with explicit assumptions, the architectures evaluated with their trade-offs, a feature-parity matrix and a ranked implementation plan with proof requirements. Raw benchmark and telemetry artifacts are checked in under docs/cloud-startup-latency/. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

Review findings on the startup benchmarks, all accepted: - bench-freestyle-floor.ts: a VM or VPC delete failure is recorded as a cleanup failure that fails the run (ok: false, exit 1) instead of a log line; a trial whose daemon never listens, whose required guest commands exit non-zero, whose pause does not pause, or whose daemon does not return after resume fails instead of contributing samples; SIGINT/SIGTERM stop scheduling and let the teardown run. - bench-vm-startup.mjs: exec, pause and destroy statuses are validated so a failed step fails the trial (a failed destroy keeps the id for the exit retry and fails the run); the attach retry sleep is clamped to the remaining budget so a large Retry-After cannot hang the run; the edge probe fails instead of returning a null sample; SIGINT/SIGTERM stop scheduling and still destroy every machine and the user before exit. Re-ran both scripts once (floor: 1 trial, API: 1 staging trial) after the change; both pass with ok: true and no cleanup failures. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
CodeRabbit follow-ups: the edge-readiness exec request is bounded by the remaining stage budget instead of the 120 s default; retry and probe sleeps return early on SIGINT/SIGTERM so an interrupt reaches teardown at once; the daemon poll aborts on interrupt and the summary reports the probe interval as the milestone uncertainty; `--trials 0 --burst 0` is rejected instead of printing a successful empty summary; the stage accumulator no longer assigns inside an expression (Biome noAssignInExpressions); the README commands start with `cd web`. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
Second structured-review round, all four findings accepted: - The create request waits the route's own provisioning budget (630 s, above its 600 s maxDuration) instead of aborting at 120 s while the server keeps provisioning, and exit-time cleanup first lists the throwaway user's machines and destroys every one, so a create whose response was lost can no longer leave a billable machine behind. - An attach counts as ready only when it answers with a trusted-carrier ws:// route, the endpoint the documented client path can dial. - The exec sample requires the guest command's exit code 0, not only an HTTP 200 from the API. - The model-plane edge counts as ready only on a 200 from the reflection route; 401/503 and an unrouted alias keep polling within the budget. Re-ran one staging trial with --edge-check after the change: ok, trusted carrier route, exec exit 0, edge 200, machine destroyed. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…a VM Third structured-review round, all three findings accepted: - bench-vm-startup.mjs: cleanup retries each destroy three times, and the throwaway Stack user is deleted only once every machine it owns is gone; while any remains the user is kept (and named on stderr) because it is the only credential that can still destroy them. - bench-freestyle-floor.ts: every machine carries the run id in its metadata and exit-time reconciliation lists on that id and deletes what survived, so a create whose response the SDK lost is still cleaned up. - bench-private-link.ts: the driver create runs inside Effect.acquireRelease (an interrupt waits for the non-cancellable provider request and the destroy finalizer is registered atomically with the machine id), machines are named with the run id, and a finalizer registered right after the VPC lists the account and destroys any run machine that outlived its own finalizer before the VPC delete runs. Re-ran each script once after the change (floor 1 trial, private link 1 trial, API 1 staging trial): all ok with no cleanup failures. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
Reserve a local projection before Cloud VM work, fence stale retries, preserve focus, and reconcile the same sidebar identity on authoritative machine state. Add behavior-level coverage for pending, retry, cancellation, stale callbacks, and projection adoption. Addresses #12904.
…t cleanup Fourth structured-review round, all six findings accepted: - bench-freestyle-floor.ts: machines get egress-only firewall rules even without a VPC (the baked daemon grants every link on its listener, so it must never face the Internet; the benchmark only uses the exec API), and the guest timing wrappers exit with the measured shell's status so a failed or timed-out startup is a failed sample. - bench-private-link.ts: exit-time reconciliation finds this run's machines by membership in the benchmark-owned VPC (the driver names every machine "cmux Cloud VM", so a name prefix never matched), and the prompt wait requires `matched: true` because `screen wait` answers `matched: false` with exit 0 on timeout. - bench-vm-startup.mjs: fleet-list reconciliation must succeed (three attempts) before the account may be removed; the account is then deleted through `DELETE /api/account` (retried per its resumable contract), which also removes the owner network the first create made; when that route fails, the owner network is removed at the provider by the same slug the application derives (pinned by a unit test against `networkSlugForUser`) before the Stack identity is deleted with the server key, and only if all of that succeeds is the run clean. Staging smoke after the change: the account route answered 500 account_delete_retryable three times (its Stack step), the fallback removed the owner network and the identity, exit 0.

…staging account deletion) Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…l closed Fifth structured-review round, all four findings accepted: - bench-vm-startup.mjs: cleanup now verifies the provider's own inventory (the control plane's list only knows rows with a persisted provider id, and this session saw a create allocate a machine it never recorded): every machine on the throwaway user's owner network is deleted and the network verified empty before any account cleanup, which makes the provider key a hard requirement of the script; the Stack session is sized from the trial count (worst-case create, attach, resume and destroy budgets per trial, capped at a day) instead of a fixed hour. - bench-freestyle-floor.ts: run-scoped reconciliation pages through the account inventory instead of reading one 200-entry page. - bench-private-link.ts: reconciliation attempts every discovered machine (with bounded retries), aggregates failures, and fails the run when any remain instead of stopping at the first error and reporting success. Re-ran each script once after the change (API 1 staging trial, floor 1 trial, private link 1 trial): all ok with complete cleanup. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

…unt route's 202s Sixth structured-review round, all four findings accepted: - bench-freestyle-floor.ts and bench-private-link.ts: reconciliation pages are read with retries, the ids found before a failed page are still destroyed, and an inventory that could not be read to the provider's totalCount is reported as its own cleanup failure. - bench-vm-startup.mjs: the provider inventory sweep pages until the provider's totalCount is covered and returns partial results plus a completeness flag, so a truncated or failed listing keeps the run unverified (user kept, exit 1) instead of reporting the network clean; the account route's two 202 outcomes are told apart: `deletionPending` is waited on, `cleanupIncomplete` means the identity is gone and only the owner network is verified and removed. Re-ran each script once after the change (API 1 staging trial, floor 1 trial, private link 1 trial): all ok with complete cleanup. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…ound attach requests Seventh structured-review round, both findings accepted: - The identity-delete fallback runs only when the account route answered with its resumable contract (`retryable: true` three times); an unclassified failure keeps the throwaway user so the route can be retried with its state intact, and the run exits 1. - The attach stage's deadline now bounds each request (the remaining budget is the fetch timeout, and a request is not started once the budget is spent), so the stage cannot run a full request timeout past its budget. Re-ran one staging trial after the change: ok, retryable-failure branch exercised (staging's account route fails at its Stack step), network and identity removed. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…report after cleanup Eighth structured-review round, all three findings accepted: - bench-freestyle-floor.ts: every provider await is raced against a deadline (the SDK can keep polling a backgrounded request), so the readiness budget and the interrupt flag are always reached and the trial's cleanup still runs; a lost create is found by the run id at exit. - bench-private-link.ts: create-to-prompt is read before the first link's scope closes, so link teardown (up to a 2 s SIGKILL escalation) is no longer counted as startup. - bench-vm-startup.mjs: the report (stdout and --out) is emitted once, after teardown, and carries the cleanup outcome (control-plane and provider sweeps, account outcome, leftover ids, a kept user); `ok` is false whenever cleanup is not verified, so a stored artifact cannot claim a success the exit path later denied. Re-ran each script once after the change (API 1 staging trial, floor 1 trial, private link 1 trial): all ok with complete cleanup. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…less user, no implicit workspace Ninth structured-review round, all four findings accepted: - bench-private-link.ts: a finalizer registered before anything is created finds this run's tunnel and VPC by their slug (machines on the VPC first) and removes them, so a create whose response was lost before its acquireRelease finalizer existed is still cleaned up; a session snapshot without a workspace id fails the trial instead of measuring an implicit "current" context. - bench-freestyle-floor.ts: the VPC is deleted by its slug (the run id) when no id was received, with "not found" meaning nothing was made. - bench-vm-startup.mjs: when setup fails before a session exists, the throwaway identity is removed with the server key after the provider sweep by its slug, instead of being kept behind an unusable route. Re-ran each script once after the change (API 1 staging trial, floor 1 trial, private link 1 trial): all ok with complete cleanup. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…it for paused Tenth structured-review round, all three findings accepted: - bench-freestyle-floor.ts and bench-private-link.ts: provider requests cannot be cancelled, so every create (and, in the floor benchmark, every bounded provider call) is tracked until it settles, and teardown waits for them (bounded) before listing the inventory, so a timed-out or interrupted create cannot allocate behind the sweep; an unsettled request is reported as a cleanup failure. - bench-freestyle-floor.ts: a machine that reports `pausing` is polled until it is `paused` before the resume measurement starts, so the start cannot race the freeze. Re-ran both scripts once after the change (floor 1 trial, private link 1 trial): ok with complete cleanup; the floor trial reported paused before start. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…n; bound setup calls
Eleventh structured-review round, all four findings accepted:
- bench-vm-startup.mjs: the application's account deletion is the only path
that removes its own rows, so when it does not complete (a retryable or
unclassified failure) the benchmark now removes only the provider-side
owner network, keeps the Stack identity with the exact retry command on
stderr, and exits 1; a `202 {cleanupIncomplete}` is retried through the
route's resume path and, if it persists, reported as an operator
follow-up instead of a success; a user whose creation response was lost
is found by its generated email with the server key and, having never had
a session, removed.
- bench-private-link.ts: the network and tunnel setup calls are bounded and
tracked like the machine create, so a stuck provider request cannot hold
the uninterruptible acquisition open indefinitely.
- docs: the report's incidental findings describe the staging behavior that
follows (user kept, exit 1, measurements still written).
Re-ran both scripts once after the change: the private link trial is ok
with complete cleanup; the staging API trial wrote its report, left no
provider resources, kept its user (staging's route fails at its Stack step)
and exited 1 as designed.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…ht server work bench-vm-startup.mjs: a createUser response that was lost is reconciled by email with the server key; when that lookup itself fails after retries the run now reports an unknown identity and exits 1 instead of treating "no user" as a clean exit. Requests are never aborted while the server may still be working on them: attach, pause and account calls wait past the platform's 300 s bound (the routes declare no maxDuration), and the attach stage budget only gates new attempts, so teardown's DELETE cannot race an attach that is still healing the machine or writing its lease. bench-freestyle-floor.ts: reconciliation's own bounded deletes are settled before the VPC delete, which otherwise raced a timed-out delete. bench-private-link.ts: finalizer deletes are tracked so the slug-based safety net waits for them before deleting the VPC. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
… clear the settle timer bench-vm-startup.mjs: a create whose response never arrived (reset, abort) may still be running on the server with nothing recorded, invisible to both sweeps. Teardown now re-posts its idempotency key until the route answers (200 → the machine joins the destroy list, 409 → keep waiting, vm_create_failed → nothing was recorded) or the route's own 600 s deadline has passed, so the sweeps that follow are authoritative. Every provider SDK call in teardown is raced against a deadline: the SDK polls a backgrounded request indefinitely, and cleanup must never hang on it. bench-freestyle-floor.ts and bench-private-link.ts: the inventory, VPC create/delete, tunnel and destroy calls used by teardown are bounded the same way, and the settlement wait clears its deadline timer once the requests settle so a finished run no longer stays alive for the rest of the wait. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…alidators, explicit exit bench-private-link.ts: finalizers run with interruption masked and a timeout is an interrupt, so the bounded cleanup attempts are made interruptible first (as cleanupPrivateLinkResource does) or their deadline could never fire. The attach bundle is bounded and tracked like the create, so a backgrounded attach cannot run a trial forever or be abandoned by an interrupt while the sweep deletes its machine. The snapshot, terminal-id and prompt validators now fail the trial through Effect's error channel instead of throwing a defect that aborted the run past its per-trial handling and lost the report. All three: the SDK follows a 202 with a referenced timer and offers no cancellation, so a provider request that outlived its bound kept the process alive after the report. The report is written synchronously and the process exits explicitly once nothing waits on those requests any more. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
… resume double count bench-private-link.ts: the production workflow passes the machine's prompt identity to both the create and the attach (the guest installs its prompt each time) and feeds the addresses persisted at create back into the attach, which then skips a provider read. The benchmark passed neither, so it measured lighter guest work and an extra round trip. It now does the same work and the same round trips; section 4.4 of the report and its artifact are re-measured with these inputs. docs/cloud-startup-latency.md: the floor benchmark's resumeDaemonListenMs is measured from before start(), so the 143 ms already contains the 91 ms start call. The resume floor is ~0.14 s end to end, not ~0.25 s; the scenario matrix, the answer and the architecture table now derive from that figure. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…itive pulls, guard --url bench-vm-startup.mjs: the provider credential is resolved the way the runtime's client resolves it (FREESTYLE_API_KEY, or FREESTYLE_STACK_ACCESS_TOKEN with FREESTYLE_TEAM_ID, plus FREESTYLE_API_URL), from the pulled target env first and then the process environment, so a deployment on the stack-token form can run the benchmark and its cleanup. A Stack key that Vercel pulls as an empty "sensitive" value is filled from the process environment the same way, and the error names CMUX_CLOUD_VM_ENV_SOURCE=process. Every request carries the throwaway user's bearer and refresh tokens, so --url now accepts only an https origin of the selected project (its canonical host or a Vercel preview of it) unless --allow-any-url is passed; http is refused either way. bench-freestyle-floor.ts and bench-private-link.ts: the SDK client comes from freestyleClient, the runtime's own credential resolution, instead of an API-key-only constructor. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…ending the session A hostname prefix proves nothing: any Vercel tenant can name a project cmux-staging-something, and the previous check would have sent that host the throwaway user's bearer and refresh tokens. The benchmark now accepts a non-canonical --url only when Vercel's deployments API attributes that host to the selected project in its team (an error or another project's deployment is a refusal), unless --allow-any-url records that the operator checked the host. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
bench-freestyle-floor.ts and bench-private-link.ts delete a network (and, for the link benchmark, a tunnel) by the run's slug when a create's response was lost. A slug alone proves nothing, so both now refuse to start when a network or tunnel already carries the run's slug, label the network they create with the run's own id, and at teardown delete by slug only a network that carries that label; anything else is reported as a cleanup failure and left alone. bench-vm-startup.mjs: document that only the waits in flight when a signal arrives return early, so cleanup retry loops keep their backoff after an interrupt and keep running until every resource is gone. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…d to this machine bench-private-link.ts: the driver's ensureNetwork adopts an existing network on a slug conflict, so a check-then-create was a race in which the run could end up destroying a network it did not make. The network is now created with the SDK's plain create (production's rules), which fails on a conflict, so a successful create is the ownership proof for everything the finalizers later delete by its id; the tunnel create must report `created` (the driver only ever recovers a tunnel for the same client key, and the run's key is fresh); and the slug-based safety net deletes a tunnel only when it carries the run's own client key. bench-freestyle-floor.ts: a clone briefly runs the source machine's daemon until the supervisor re-keys it, so the readiness probe now includes the image's own health predicate (process, listener, and the daemon's bound instance id equal to this machine's). `daemonListenMs` counts only the daemon that is valid for this machine; the report's floor is re-measured.

…tion before use install-cmux-tui-client.sh gains --attest-signer-workflow: after the manifest download it runs `gh attestation verify` against the Sigstore attestation cmux-tui-artifacts.yml signs, scoped to that workflow, its repository and (with --expected-commit) the source commit, and fails closed before reading a hash or running the client. reload-build.yml passes it, so an artifact host cannot substitute a build the workflow then executes (CWE-494).

…_invalid_request The shared validator now only reports validation state. Both the create and rename routes answer an unusable displayName through one helper that reads the new vmErrors.displayName copy (all 20 catalogs) in the request locale and keeps field/maxLength details machine-readable, matching the other field errors' shape so the app renders title, message and next step. The control- character regex carries the Biome suppression the linter expects; the ESLint directive never applied to it. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…iling, fix the README sample The extension-profile validator accepts IOS_APPSTORE_PROFILE_VALIDATION_TIME so the lane-identity test validates its 2099 fixture against a fixed instant instead of the real clock; release lanes leave it unset.

…attestation A remote install with no flags must still run `gh attestation verify` against the publishing workflow and fail closed without a valid attestation; only the explicit --allow-unattested opt-out installs without gh, and it warns. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…by default install-cmux-tui-client.sh now defaults --attest-signer-workflow to manaflow-ai/cmux/.github/workflows/cmux-tui-artifacts.yml, so the release, nightly and CI lanes that download a published client verify its Sigstore build-provenance attestation before trusting a hash or running it; those steps get GH_TOKEN for gh. --allow-unattested is the one explicit opt-out, and reload.sh passes it only on a dev Mac whose gh has no token, with the installer's warning. Every candidate client postdates the attestation step (2026-08-25), so no lane changes which build it bundles. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

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`.

pendingRowStepsAsideOnceItsMachineHasARow predates #12919, which made a created machine's own row inherit its stand-in's node id and lets a failed create's row stand in for its machine. The test still expected the old node ids, so it has failed on main since then; no required check executes cmuxTests, and test-e2e run 35558140619 surfaced it here. The rows helper now renders a machine's own row as "<machine id>@<node id>", so each assertion states both which row is present and whose identity it carries.

#12919 (021f792) made New Machine creation optimistic: once a running create's machine appears in the fleet list or catalog, its row keeps the `pending-machine:<operation>` node ID so selection and expansion survive adoption (see committedProjectionKeepsThePendingNodeIdentityUntilFleetAdoptsIt). pendingRowStepsAsideOnceItsMachineHasARow still expected `machine:<id>`. Assert the new identity and that the row is the adopted machine, not a stand-in: the stand-in is gone, one row remains, and it shows the created machine.

* test(terminal): restore the presented-surface fixture contract so package tests compile `swift test --package-path Packages/macOS/CmuxTerminal` has not compiled on main since merge 38b32bb: TerminalSurfaceRendererCallbackTests calls `PresentedSurfaceFixture(installRendererCallbacks: false)`, but the fixture initializer only takes `windowVisibleAtCreation`. The flag came from the issue-2824 branch (77c46d0, 6fe70f6) and was dropped when the fixture was reworked for the native callback lifecycle (8008b7c, 97c6088); the merge re-applied the test call without the fixture side. Package tests only register render callbacks through the fixture (RendererCallbackTestSupport), so a fixture that skipped registration would leave `cmux_test_ghostty_renderer_present` with nothing to route. Restore the calls to `PresentedSurfaceFixture()`, the combination that was green at 0251a44. Verified locally: 294 tests in 37 suites pass. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(popover): stop rewriting the presentation binding during view update `ArrowlessPopoverAnchor.updateNSView` calls `coordinator.dismiss()` on every update where `isPresented` is already false. PR #13311 (01f0a50) made `dismiss()` write `isPresented = false` on the no-popover path, which SwiftUI reports as "Modifying state during view update" because updateNSView runs inside the view update. The sidebar footer mounts two anchors whose parents re-evaluate on every `selectedTabId` change, so every workspace switch emitted faults and `SidebarWorkspaceSwitchLayoutFaultTests` failed with 15 of them. Pass `resetPresentation: false` from updateNSView: the binding is already false on that branch, so the write was redundant. `popoverDidClose` still resets the binding when AppKit closes a live popover. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * test(cloud): satisfy the plus menu's sign-in gate and route Cmd+Y through a registered window `NewCloudWorkspaceShortcutTests` never passed: the plus menu deliberately hides its Cloud rows unless the account is signed in (#12305, mirroring the command palette and File menu), and a test `AppDelegate()` has no account flow. The XCTest version crashed the app host on `rows[1]`, xcodebuild restarted it, and the lenient gate accepted the partial run; #13178 now rejects that and #13193 migrated the suite to Swift Testing, so the failures became visible. Inject the signed-in state through the existing `isAuthenticated:` seam, add signed-out coverage of the gate, route the Cmd+Y event through a registered main window (as `testReboundKeyRoutesAndOldKeyDoesNot` does, since shortcut routing bypasses events bound to windows the delegate cannot resolve), and register a window context for the unavailable-Cloud check. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * test(chrome): assert the composited Bonsplit chrome contract instead of a stale alpha hex `WorkspaceChromeColorTests` expected `bonsplitChromeHex` to return `#1122337F` (theme with opacity as alpha). Since b6d3470 (2026-05-19) `compositedTerminalColor` composites the theme over the window base and returns an opaque color, and 4cbb354 made that deliberate: Bonsplit derives its tab glyph contrast from the rendered backdrop, and an `#RRGGBBAA` hex reproduces the white-on-white bug it fixed. The tests kept failing unnoticed because the app-host gate only counted "unexpected" XCTest failures until the strict check (acedf3f) reached main through #12053. Exercise the `chromeBackgroundColor` seam that every production call site uses with literal expectations, verify the ambient default path against the resolver plus independent blend arithmetic so the result is deterministic under any host appearance, and keep coverage for opaque, shared-backdrop, pane-clear, pane-border, and explicit translucent chrome colors. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * test(tmux): wait for the main window to adopt the mirror pane before sending keys `RemoteTmuxMirrorPaneInputMappingTests` required `panel.surface.uiWindow != nil` right after selecting the workspace. A manual-I/O mirror pane spawns eagerly in its hidden bootstrap window, which `uiWindow` deliberately excludes, and the main window's portal adopts the pane host only once AppKit and SwiftUI get run-loop time; `waitForLiveSurface` returns immediately for an already-live surface, so the check ran before adoption and the four key-delivery tests failed at line 176. The failure was hidden until the strict app-host gate. Order the harness window front and pump the run loop until the surface and its native view are in that window, as the other hosted-view input suites do, and assert against the harness window instead of any window. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * test(browser): report the refused connection through the navigation delegate `browserPanelRetriesDiscardedRestoreAfterConnectionRefused` waited up to 30s for WebKit to fail a provisional load to a bound-but-unlistened loopback port. On the hosted app-host runners that failure never arrives: the load neither fails nor commits, so the test timed out at line 147 (no "provisional navigation failed" log line appears for it in any shard). Stop the in-flight load and report `NSURLErrorCannotConnectToHost` for the attempted URL through the panel's real navigation delegate, the pattern `BrowserFailedNavigationReloadTests` already uses. The restore bookkeeping, error page, `restore_pending` clearing, and retry policy under test run unchanged and every assertion is kept. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(cloud): scope reserved-workspace cleanup to its pending card and return the bind window PR #13202 (5d616a7) imported `CloudMachineWorkspaceAdoptionTests` and `CloudMachineWorkspaceResolutionTests` from the still-open 13141-cloud-vm-workspace branch without the production changes they assert, and its own run skipped the app-host shards, so they landed red: - `NewMachineSheetPresenter.closeReservedWorkspace` closed the whole workspace, which is a no-op for the last tab and discards user panes added next to a creating card. Port the branch behavior: remove only unadopted loading cards owned by the cancelled machine, clear that binding, keep user content, and give a last-tab loading workspace a local anchor first. `MachineCreateCoordinator` passes the created or reconciling machine id so cancelling machine X cannot clear a binding to machine Y (the tests now assert that scoping). - `v2WorkspaceCloudVMBind` now returns `window_id` alongside the workspace refs, as the bind acknowledgement test expects. - The resolution test selected "first" while the fixture's terminal key is "term-first"; use the key so the placement resolves as intended. - `CloudPaneCreationRetryTests` asserted `discarded` synchronously after the projection returned, but the coordinator applies its generation fence behind `CloudOperationContext.withPhase`'s recorder await, which suspends on a cold per-suite process. Settle with bounded yielding before asserting. Runtime behavior change (cancelled Cloud create cleanup); needs dogfood. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(cli): restore deferred socket connection, explicit SSH control options, and Codex stop idle observations Branch commit c8bfb58 ("fix: repair failures exposed by strict app-host CI", 2026-09-10) made `cmux vm dev|layout|env` finish local validation and dry runs before opening the socket, passed the caller's explicit ssh options into `userConfiguredControlOptions(fromSSHConfigOutput:explicitOptions:)` so a normalized `ControlPersist=0` from `ssh -G` is not mistaken for host customization, and published `idleObserved` for transcript-terminal prior turns before a legacy Codex Stop so the journal drops an obsolete running turn. The branch's later single-parent commit 38b32bb reverted `CLI/cmux.swift` to main's version while keeping the stricter fixtures, and PR #12053 landed that inconsistent state; the fixtures (CLIVMDevTests, CLIVMLayoutEnvTests, the SSH sharing tests, and the Codex missed-prompt Stop test) have failed since. Restore the three CLI changes. `SocketClient.configureAuthentication` and `SocketPasswordResolver` already exist on main, and the CmuxFoundation overload landed with the branch. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * test(cli): align CLI integration fixtures with the shipped hook, SSH, and session-list contracts The main copy of `CLINotifyProcessIntegrationRegressionTests` predates several shipped contracts that the lenient app-host gate never enforced and that 38b32bb reverted on the issue-2824 branch: Claude hook acks print `{}` (#7963), Codex resume bindings require rollout evidence so fixtures carry a `session_meta` transcript (#10100), SessionStart publishes a binding so `/clear` counts start after the clear, fresh-terminal SSH startup commands are script paths that the support decoder must read, cmux control-path options follow a resolved `ssh -G` (#8308), and `ssh session list` reports the localized "remote state unavailable" summary with `--json` detail (#9971). The missed-prompt Codex Stop test now asserts the restored `agent.idle.observed` for the prior turn. Flagged for review: the three `ssh pty-attach` cases now expect only `workspace.remote.pty_bridge` once the endpoint is established, matching #12726's `preserveLifecycleForRecovery`; if pre-READY bridge failures were meant to keep reconciling, the flag should be set only after READY instead. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * test(workspace): restore the app-host repairs for fork, focus recovery, and shortcut routing Merge 8d33410 on the issue-2824 branch took main's copy of `cmuxTests/WorkspaceUnitTests.swift` wholesale and discarded the branch's September repairs (c8bfb58, c402b9c, 2127d97); PR #12053 then landed without them while the strict gate started counting the failures. Restore them against current production, plus the shortcut-suite fixes: - Fork in a remote workspace: `sshBootstrapArguments` has used `/usr/bin/ssh` since #9114, and agent socket propagation requires a socket that exists on disk (3bf87e3), so bind a real unix socket and expect the absolute path. - Fork Conversation context actions dispatch asynchronously (#7259, #8173); await the fork panel before asserting. - Git branch and pull request updates publish through `sidebarObservationPublisher` since #6226, not `objectWillChange`. - Config sanitization: `addWorkspaceIfActive` rebuilds templates from the font-size lineage since #8543; override the lineage hook instead. - Focus recovery: AppKit focus is authorized only for a registered, selected workspace whose window carries the main-window identity; use the `TerminalPortalTestWorkspace` fixture and the same registration/pump path as `WorkspaceTerminalFocusRecoverySwiftTests`. - Shortcut routing: clear both Cloud defaults after 9c2ba78 swapped them; neutralize Ghostty's imported goto_split fallback (⌘] by ANSI keyCode) in the unshifted-symbol test and assert the digit shortcut does not match; wait for the async runtime start before judging keyDown forwarding (skip loudly without a live surface); wait for the portal to mount before the second-Escape check. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(restore): keep a restore identity when the persisted surface id collides Since #13098 (e0e77eb), `newTerminalSurfaceOutcome` treats a nil `restoredSurfaceId` as an interactive create and routes it to the selected pane's Cloud source. Session restore passed nil whenever the persisted panel id was still live (duplicate-workspace or restore-into-live), so a legacy managed-Cloud SSH workspace restored into a live manager was turned into a remote tab create: the scaffold panel stayed startup-suppressed with no initial command and `TabManagerSessionSnapshotTests` failed to unwrap it. Mint a fresh UUID on collision instead of nil; it is free by construction, so the restore keeps its identity and the old-to-new remap works as before. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * test(terminal): align snapshot, projection, terminal, and browser fixtures with shipped contracts Stale expectations and fixed-spin timing in app-host suites that the lenient gate never counted: - Cloud-projected panes restore as manual-mirror reservations with a staged remote identity (#12675), not a local placeholder projection. - Restore reuses the persisted runtime id when free (aff0e32), so assert liveness rather than a new id; the catalog ignores writes for a Cloud machine without a registered provider (#11877), so register the fixture provider before publishing. - Wheel sync requires an authoritative scrollbar response (bbc3edf); the fixture now answers like `AuthoritativeScrollbarSurfaceView`. - Search overlay mount, first-responder focus, runtime creation, and the visibility-restore redraw run through deferred main-actor tasks; wait for them with the class's `waitUntil` helpers instead of fixed run-loop spins. - Owning the socket path lock is definitive (959f38a): a refused inode left by a dead listener is replaced, so the restarted listener accepts. - The split-divider hit band extends `dividerHitExpansion` past the divider (667cc43); derive the pass-through boundary from the constant. - Browser page background blends against Ghostty's effective terminal color scheme, which is host dependent; read the same preference the product uses. - Cloud Machines defaults on in dev builds (#12318); pin the toggle off for the default-mode palette contract. - Prepared navigation requests keep the caller's cache policy (#13003). Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * test(browser): align lifecycle, identity, host-view, loopback bridge, and portal rebind tests with shipped contracts Browser app-host suites that the lenient gate never counted: - `BrowserPanelWebViewLifecycleTests`: out-of-range discard delays are rejected to the default (the cmux.json loader relies on the nil), and the panel's own `isLoading` stays true for the indicator floor, so wait for both flags and assert no discard blockers before discarding. - `browserNavigationUsesEmbeddedWebKitIdentity`: WebKit reports the native identity as nil or "" (#9482); accept either. - `WindowBrowserHostViewTests`: production routes Dock-divider hits by yielding to AppKit so the live sidebar tracker receives them (#10902, e2e3818); the tests asserting the portal owns and forwards the hit were merged red against a design that never shipped. Realign the stale-frame test to the pass-through contract and remove the four own-and-forward tests with their fixtures. **Flagged for review:** if own-and-forward is still wanted, that is a hit-testing product change for its own PR. - `testRemoteWorkspaceRuntimeBridgeAliasesMultipleLoopbackPortsFromSamePage`: the navigation delegate restarts main-frame loads to apply the user-agent policy (11c6efe); a direct `loadHTMLString` with an HTTP base skipped that step, so the data load was cancelled and replayed as a deferred request. Apply the identity first and assert the document is current. - `portalRebindPreservesDocumentAndRoutesRefreshToTheSameWebView`: the portal host is a theme-frame sibling of `contentView` for non-glass windows (#12929); assert same-window instead of descendant-of-contentView. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * test(terminal): wait for asynchronous runtime creation in the remaining direct-interaction tests The same "Expected runtime surface before ..." precondition that 9f258dd made wait for the deferred runtime start still sampled after a fixed run-loop spin in the detach-race, close-lifecycle, repeat-key, and repeat-IME tests, and CI on the branch head showed them failing that way. Use the class's `waitUntil` for those four sites too. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * test(cli): model surface.respawn for respawn-pane and give the Codex stack fixture rollout evidence `cmux respawn-pane` has sent `surface.respawn` instead of `surface.send_text` since #5465 (8cafcc3); the window-flag fixture's mock still rejected that method, so the CLI exited 1. Answer `surface.respawn`, asserting the window and surface ids, `tmux_start_command`, and that the shell-invoked command carries the user command but never the `--window` flag, which is the test's intent. The Codex interrupted-stack fixture's transcript had no `session_meta` line, so `CodexSessionResumeVerifier` (#10100) found no rollout evidence and the prompt published `surface.resume.clear`. Prepend the session line as the other Codex fixtures do. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(socket): keep mobile.panel.artifact.fetch off the local socket and advertise the served artifact reads 02c1ba4 removed `mobile.panel.artifact.fetch` from the socket worker methods because it needs the authenticated mobile execution context, but that half of the change was lost in a merge: the policy still routed fetch to the worker lane, which has no handler for it, so the local socket answered `internal_error` instead of the `method_not_found` boundary that `TerminalControllerSocketSecurityTests` pins. Restore the removal. `system.capabilities` never advertised `mobile.panel.artifact.stat` and `.thumbnail` although both are served on the worker lane (04ff18e added them only to the test's expectation); advertise those two and keep fetch out. The remote relay allowlist is unchanged. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * test(remote): align tmux seed transport, SSH, socket command, and port scanner fixtures with shipped behavior - `RemoteTmuxPaneSeedTransportTests`: manual-I/O mirror panes spawn eagerly (#9272) and stay runtime-backed after portal churn (#9769), so the pane renders its assigned grid before a seed arrives and nothing was retained. Publish a larger tmux pane grid than any test surface applies so the retention under test sees the lag it exists for. - `SSHRemoteCWDRegressionTests`: the persistent-PTY exec helper runs only with `protectsFromHangup: true` (cd9f34f); pass it, and widen the first-spawn guard. - `SSHDeepSleepReattachTests`: a Cloud-owned workspace rejects launch overrides on splits (#13098); create the custom-identity pane before configuring the remote connection. - `SSHConfiguredRemoteCommandHostTests`: ssh-pty-attach validates the bridge `daemon_version` before dialing (#12726); the mock now reports one. - `CloudManualMirrorTransportTests`: the pane failure card uses the short title since 9bf6cb8. - `SurfaceSocketCommandTests`: `vm.workspace_new` admits its optimistic workspace through the active main window (#13152, #13155), so bind a bare window to the fixture context; a receipt without a starter terminal costs one snapshot (6d43ea6). - `PortScannerPublicationTests`: the forced-result acknowledgement hops off the main actor, so an unchanged port set may be deduped under a later refresh; drain publications until the retirement lands. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * test: align mobile artifact fetch lane assertion * repair: close remaining full-suite contracts * test(restore,sidebar): align two stale contracts with shipped behavior testRemoteWorkspaceAutoResumeKeepsRemoteStartupCommand asserted the restored remote panel's local spawn cwd equals the remote-host path. It never can: OneShotTerminalLauncherStore.enterableWorkingDirectory rejects a path that is not locally enterable, which is what keeps the owning shell valid (#7031). The remote cwd does survive restore — as the panel's trusted remote directory report, and as the `cd` prefix the resume input carries (both already asserted). Assert it where it actually lives and pin the spawn cwd to nil. testSidebarPullRequestsTrackFocusedPanelOnly expected a background panel's PR to be hidden from sidebarPullRequestsInDisplayOrder(). That list is documented as the workspace's deduplicated rows in pane/tab order, both consumers (taskStatusSignals, the control-sidebar snapshot) want every panel, and the sibling branch test asserts the same all-panel model. Focus scoping lives in the `pullRequest` binding, which the test already covers. Renamed to match. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test: give Cloud catalog tests live destination workspaces #13196 made SurfaceCatalog.validateOwnership refuse a destination that is not a live workspace. That rule stays. Tests that projected, restored or opened browsers into a made-up workspace ID now failed with destinationNotFound, timed out waiting on a provider that was never called, or passed a later check for the wrong reason. LiveWorkspaceFixture registers real Workspace objects and hands the catalog a CloudWorkspaceRenameService that resolves them, the way the app's composition root does. Its workspaces() list stays empty so the native projection coordinator does not start mirroring into them. For tests on SurfaceCatalog.shared, withAppRegistration registers the TabManager as a windowless main-window context for the test body.

Its last clause only admitted replacing an accepted name when the local panel still carried `.auto` provenance, but since 1e1d319 an accepted daemon name reconciles locally as `.remote` and the owner lives in the tab's nameAuthority. Every agent title after the first accepted one was refused, so "Failed agent rename keeps the accepted title", "Mirroring an agent-named placement does not block its next agent title" and "An older automatic result and old snapshots cannot replace an accepted name" failed on their second agentName call. Admit an automatic rename when no write is pending and the accepted tab name is owned by the daemon's `auto` authority. User-owned names, pending writes and local user titles on any projection still refuse it. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test: expect adopted machine rows to keep the pending create identity #12919 (021f792) made New Machine creation optimistic: once a running create's machine appears in the fleet list or catalog, its row keeps the `pending-machine:<operation>` node ID so selection and expansion survive adoption (see committedProjectionKeepsThePendingNodeIdentityUntilFleetAdoptsIt). pendingRowStepsAsideOnceItsMachineHasARow still expected `machine:<id>`. Assert the new identity and that the row is the adopted machine, not a stand-in: the stand-in is gone, one row remains, and it shows the created machine. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix: restore per-display noVNC targets and refresh stale Cloud tests Product (#13196 regression): the 6db7593 main merge into 13192-cloud-display-ownership took main's CmuxTuiSurfaceProviders.swift and CloudPortRoutePlan.swift, dropping eb3edd7's per-display ports. 23c807b restored the display coordinator but not these hunks, so withPrivateBrowserURL rewrote every display to 6901 and a daemon pointer without a discovered target fell back to display 1. Restore both hunks and drop the duplicate port-less privateDesktopURL overload. Tests: - CloudDisplayCatalogTests: 178d35e (#13196) made every guest command run `list` as a readiness probe, so fakes dispatching on " list" answered creation with the list catalog. Dispatch on the create action line, and pin the command shape. - CloudPortOpenRegressionTests: 178d35e (#13196) filters RFB/noVNC ports only when the display catalog owns them (displayPortsOwned). Assert both the desktop and non-desktop results. - CloudTreeOneMachineManyWorkspacesTests: #12740 added a final Resources section under each machine. Expected trees include it. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix: publish every guest display from daemon graph updates The 6db7593 main merge into 13192-cloud-display-ownership (#13196) put back main's [desktopDisplayResource()] pools in CmuxTuiSurfaceProvider's refresh, publish and delta paths. 23c807b restored the display coordinator lifecycle but not these pools, so a display created beyond display:1 vanished on the next daemon publish, and a delta that touched it removed it. Restore eb3edd7's displayResources pools, the display-kind delta check, and the injectable displayCoordinator. Drop the now-unused desktopDisplayResource(). Adds a test that creates display:2 through the provider and asserts that both displays and their ports survive a full publish and a display delta. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test: fence the fake Cloud projection reply with its mutation cursor aDetachedTerminalDropsItsStaleTabBeforeMoving installs a daemon graph since c402b9c (#13403). When the placement lane drains it reconciles against that graph, which predates the projected tab, and clears tab_projected. The real reply always carries a mutation cursor (CmuxTuiSnapshotParser.placedTab requires one) that fences exactly this; the fake returned none. Give the fake a projectCursor and set it ahead of the installed graph. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test: register the restored window before relinking Cloud projections #13196 made SurfaceCatalog.validateOwnership refuse a destination the app cannot resolve, so SurfaceCatalog.shared no longer relinked a restored projection into a TabManager that no main window owns. Register it for the test body with LiveWorkspaceFixture.withAppRegistration, as #13651 does for CloudClosedPanelRestoreTests. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test: wait for the relay ports kick, not the first relay line Since #8442, a relay prompt also reports shell state. Both RPCs run in separate background children, and the zsh prompt-refresh test waited only until the log was non-empty, so it could read report_shell_state alone. Wait (deadline-bounded) for the ports_kick line itself, in the zsh test and its bash sibling. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(cli): relay output of an SSH session that ends right after auth The expect wrapper watches the first two seconds after sending the password for a rejection with log_user 0. A session that authenticates and exits inside that window hit the eof branch and its output was dropped. Flush the buffered output before exiting. #13207 replaced the test's 9 s sleep with a FIFO release, which is what exposed this. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test: restore the no-connection path for rejected vm dev input 4120e35 taught runVMDev that invalid input never connects: keep the listener open, then check its backlog after the CLI exits. #13207 dropped that again, so each rejected run waited 60 s for a mock-server expectation that only the listener closing (after the wait) fulfills. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test: drain the terminal while the SCP host-key failure runs The pty case read the master only after the CLI exited. A pty's output queue holds about 1 KiB and the host-key failure report is longer, so the CLI blocked writing stderr until the 30 s timeout. Read the master on a thread while the CLI runs. The test starts its own sshd; no runner host dependency is involved. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test: fail fast when a gated Cloud call ends before its fake is entered Every app-host restart in the 09-21/09-22 shard logs I sampled was a Swift Testing time-limit hit in one of two suites, and each hit relaunches the test host: - SurfaceCatalogTests: when catalog.project threw before reaching the provider (destinationNotFound, fixed by 3dc91b2), each gated test parked in MaterializeGate.waitUntilEntered() until the 300 s limit. Five tests restarted the host one after another, about 25 minutes per shard. - CloudDisplayCatalogTests: when the fake no longer recognized the create command (fixed by 70eaf44), create() failed before the exec started and `await started.result` parked until the 60 s limit. The waits now also end when the caller's task finishes, so the next such setup failure is an ordinary failed #require. The cancellation test also waits on its own cancellation signal instead of a 60 s Task.sleep. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test: reveal a retired terminal through the portal rebind, as the app does Since #12607 hiding a terminal removes its hosted view from the window, and only a bind reinstalls it. The test flipped portal visibility on the detached view, so no size commit could ever land and the final shrink check failed every run. Rebind like TerminalPortalReconciliation and drop the wait loop. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test: pin key-window status in terminal focus suites The app-host test process runs headless and is usually not the active app, so makeKeyAndOrderFront never makes a programmatic window key. Terminal focus paths gate on isKeyWindow (automatic first-responder apply, focus redraws, deferred focus reapply, ensureFocus window activation), so these suites passed only when an earlier test in the shard had activated the app. Share the existing KeyStatusTestWindow and use it in WorkspaceTerminalFocusRecoveryTests, WorkspaceTerminalFocusRecoverySwiftTests and TerminalNotificationDirectInteractionTests. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test: report which layer holds off-plan tmux mirror geometry offPlanGeometryWithUnchangedSizingInputsReconverges fails every run with all three output-parity re-arms spent and the hosted view still at the perturbed 0.8 divider. A standalone bonsplit replay of the same sequence converges, and a sibling test without a bound (portal-visible) workspace heals the same displacement. Add the live split view's arranged widths and the split model's imposed extent to the failure message so the next run shows whether bonsplit refused the apply, the imposition was cleared, or the portal did not follow. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix: restore Cloud projections before the workspace is published TabManager.restoreSessionSnapshot restores each workspace's surface projections before it assigns tabs, so SurfaceCatalog.restore's ownership check could not find the destination and silently dropped every restored remote projection. Check ownership against the workspace being restored. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test: repair stale and broken app-host expectations - CLI ssh attach: count identity UUIDs exactly; #11497 added an auth token uuidgen - device mirror directories: give the fake device trusted presence (e3d424c gate) - font zoom mirrors: deltas from the 8pt inherited base (e6926fb arithmetic) - Computer Use refresh: fake daemon reply was invalid JSON in a raw string (#13599) - quit alert: compare button alignment rects, not padded frames - remote split cwd rescue: cwd travels as CMUX_REMOTE_INITIAL_CWD since #12054 - default freestyle split: Cloud-owned splits route to Cloud since fa5dc4c Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test: activate the app host before waiting for terminal focus `focusTerminalForTesting` waits for `window.isKeyWindow` before it hands first responder to the terminal, but `makeKeyAndOrderFront` only makes a programmatic window key while the test host is the active app. The app-host process starts inactive under `xcodebuild test`, so the wait succeeded only when an earlier test in the shard happened to activate the app. Its callers use a real `createMainWindow()` window, which cannot be swapped for `KeyStatusTestWindow` the way the pinned focus suites were. Activate explicitly, and give the wait a CI-appropriate timeout: the activation and the key-window transition land on later main run-loop turns, and the pump's one-second default expires before the window goes key on a contended runner. Observed on run 35743588302: `plainTerminalTextDoesNotResolveAppShortcutContext` (shard 1/6), `keyboardCopyModeKeyClearsTerminalUnread` and `workspaceFontSizeShortcutPreservesBackgroundTerminalUnread` (shard 2/6) all fail at this helper's return value, and shard 6/6 shows the same process state directly as `NSApp.keyWindow -> nil`. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test: give standalone terminal fixtures a live portal authority `setVisibleInUI` and `setActive` fold their request through `Workspace.portalRenderingEnabled(for:)`, which denies any workspace id the app delegate cannot resolve to a selected tab. Three direct interaction tests build their surface with `tabId: UUID()`, so once any earlier test installs an `AppDelegate.shared` the authority denies the portal, the hosted view is never actually made visible or active, and the fixture stops exercising the behavior it asserts: the surface never takes Ghostty focus and never schedules a visibility-restore redraw. Register a real selected workspace and build the surface with its id, so the fixture gets the same authority the app grants the selected tab. This is the fixture, not the product: the authority check is deliberate, and denying an unresolvable workspace is what keeps queued portal callbacks from reviving an inactive workspace. Fixes on run 35743588302 shard 4/6: `testKeyDownRecoveryDoesNotReplayFocusAfterResponderMovesAway`, `testVisibilityRestoreRefreshesSurfaceWhileTerminalIsInactive`, and `testDirectFirstResponderFocusRefreshesCursorStateAfterForeignResponder`. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * chore: normalize project.pbxproj after merging main Run 35763999808 failed `Fast static checks` before any macOS job could start, so the app-host test fixes on this branch were never exercised: error: cmux.xcodeproj/project.pbxproj is not normalized. Run scripts/normalize-pbxproj.py to fix. The branch head alone checks clean. CI builds the merge of this branch into main, and that merge is what leaves the file unnormalized, so the failure does not reproduce without merging main first. The change is one build-phase entry moving back into alphabetical order. `LiveWorkspaceFixture.swift in Sources` keeps the same UUID and the same occurrence count, and `scripts/lint-pbxproj-test-wiring.sh` still reports ok across 1049 test files, so no target lost a source file. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * Drop a cancelled fork-probe request, and name the inputs behind the last two app-host failures (#13744) * fix: drop a cancelled fork-probe request while it waits behind an active probe A second fork-availability request for the same panel with a different fallback snapshot parks in `applyPendingForkValidations`' contention branch: it restores its request to the pending queue and awaits the active probe. That wait had no cancellation handler, unlike every other wait in this type, so a cancelled caller kept its request in the queue until the active probe finished. The probe's completion restarts the single-flight refresh for whatever is still pending, and the cancelled request rode along: its fallback was probed and its result replaced the surviving request's validation for that panel. Give the wait the same cancellation handler its siblings have, and drop the waiter's own pending requests when it is cancelled, so the restart that follows the active probe sees only live requests. Covers cancelledSharedForkProbeRefreshPreservesSurvivingFallbackSnapshot, which failed when the restart won the race against the cancelled task's own cleanup. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test: name the input behind the off-plan re-arm and the sidebar reveal double pass Both failures currently report only their outcome, and each has two incompatible explanations that the message cannot tell apart. offPlanGeometryWithUnchangedSizingInputsReconverges reports `rearms=3` with `imposed=nil`. That is either three recovery passes that ran and failed to impose, or a re-arm budget already spent before the perturbation, in which case no recovery pass ran at all. Bracket the recovery window with the existing DEBUG sizing counters and report the budget at perturbation time plus the planned outers. visibilityToggleKeepsAppKitTableContainerMounted reports exactly two projections per row. Report how many the first run-loop turn produced and which async signals landed inside the reveal window (the workspace directory channel, workspace order, the shared agent index), since the hidden phase queues main-queue work that can land during the reveal. No assertion changes. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 5 <noreply@anthropic.com> * test: repair the remaining app-host failures and the shard-2 host relaunches (#13759) Most of these share one cause: the app-host test process runs headless and is not the active app, so AppKit and WebKit withhold state the tests assumed. NSApp.keyWindow is nil, makeKeyAndOrderFront never makes a window key, occlusionState never carries .visible, and behind XCTest's shielding window WebKit suspends requestAnimationFrame entirely. The four shard-2 host relaunches were one hung await: renderMarkdown awaited two animation frames inside callAsyncJavaScript (cd9f34f), which behind the shielding window never fire, so four MarkdownPanelTests cases each hung until XCTest's five-minute allowance killed the host. Every WebKit call in that file now fails fast with a stated reason instead of hanging, renderMarkdown waits on the viewer's own render contract, and the scroll restore the rAF await was papering over no longer clobbers a scroll that lands after a content update. Two real product regressions: windowless shortcut events stopped pruning the orphaned main-window context (6d7b23f), and ticket minting read the routes and the v2 installation identity as two separate cache reads. No assertion is weakened; several are strengthened. Rebased onto fix/app-host-green after 87a7016 landed a different remedy for the same key-window cause. The three focus tests this branch fixed through a test-target MainWindowKeyStatusPin (a swizzle of NSWindow.isKeyWindow, needed because CmuxMainWindow is final) are exactly the three that commit fixes by activating the app host and widening the pump's timeout. The pin is dropped: activating the host makes isKeyWindow true for real rather than forcing the answer, and a process-wide swizzle installed for one helper is a worse neighbour to the rest of the shard. cmuxTests/AppDelegateMainWindowTestingSupport.swift is no longer touched by this branch. Co-authored-by: Claude Opus 5 <noreply@anthropic.com> * test: measure Cloud title ink beyond the icon and trace measured invalidations Real rendering at 75% and 1x reproduces disconnected icon ink misidentified as the title. Retain the alignment tolerance and verify that displaced text still fails. Enable DEBUG tracing only during the existing sidebar and minimal-mode measured intervals. Count assertions and timing remain unchanged. * test: preserve carrier preparation before fleet discovery * fix: retain independent cloud carrier prewarming --------- Co-authored-by: austinpower1258 <austinwang115@gmail.com> Co-authored-by: Claude Fable 5.1 <noreply@anthropic.com>

…meouts (#14210) * test(terminal): restore the presented-surface fixture contract so package tests compile `swift test --package-path Packages/macOS/CmuxTerminal` has not compiled on main since merge 38b32bb191: TerminalSurfaceRendererCallbackTests calls `PresentedSurfaceFixture(installRendererCallbacks: false)`, but the fixture initializer only takes `windowVisibleAtCreation`. The flag came from the issue-2824 branch (77c46d0c02, 6fe70f6f68) and was dropped when the fixture was reworked for the native callback lifecycle (8008b7c062, 97c60889b4); the merge re-applied the test call without the fixture side. Package tests only register render callbacks through the fixture (RendererCallbackTestSupport), so a fixture that skipped registration would leave `cmux_test_ghostty_renderer_present` with nothing to route. Restore the calls to `PresentedSurfaceFixture()`, the combination that was green at 0251a448c9. Verified locally: 294 tests in 37 suites pass. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(popover): stop rewriting the presentation binding during view update `ArrowlessPopoverAnchor.updateNSView` calls `coordinator.dismiss()` on every update where `isPresented` is already false. PR #13311 (01f0a503b9) made `dismiss()` write `isPresented = false` on the no-popover path, which SwiftUI reports as "Modifying state during view update" because updateNSView runs inside the view update. The sidebar footer mounts two anchors whose parents re-evaluate on every `selectedTabId` change, so every workspace switch emitted faults and `SidebarWorkspaceSwitchLayoutFaultTests` failed with 15 of them. Pass `resetPresentation: false` from updateNSView: the binding is already false on that branch, so the write was redundant. `popoverDidClose` still resets the binding when AppKit closes a live popover. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * test(cloud): satisfy the plus menu's sign-in gate and route Cmd+Y through a registered window `NewCloudWorkspaceShortcutTests` never passed: the plus menu deliberately hides its Cloud rows unless the account is signed in (#12305, mirroring the command palette and File menu), and a test `AppDelegate()` has no account flow. The XCTest version crashed the app host on `rows[1]`, xcodebuild restarted it, and the lenient gate accepted the partial run; #13178 now rejects that and #13193 migrated the suite to Swift Testing, so the failures became visible. Inject the signed-in state through the existing `isAuthenticated:` seam, add signed-out coverage of the gate, route the Cmd+Y event through a registered main window (as `testReboundKeyRoutesAndOldKeyDoesNot` does, since shortcut routing bypasses events bound to windows the delegate cannot resolve), and register a window context for the unavailable-Cloud check. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * test(chrome): assert the composited Bonsplit chrome contract instead of a stale alpha hex `WorkspaceChromeColorTests` expected `bonsplitChromeHex` to return `#1122337F` (theme with opacity as alpha). Since b6d3470668 (2026-05-19) `compositedTerminalColor` composites the theme over the window base and returns an opaque color, and 4cbb354cfc made that deliberate: Bonsplit derives its tab glyph contrast from the rendered backdrop, and an `#RRGGBBAA` hex reproduces the white-on-white bug it fixed. The tests kept failing unnoticed because the app-host gate only counted "unexpected" XCTest failures until the strict check (acedf3f244) reached main through #12053. Exercise the `chromeBackgroundColor` seam that every production call site uses with literal expectations, verify the ambient default path against the resolver plus independent blend arithmetic so the result is deterministic under any host appearance, and keep coverage for opaque, shared-backdrop, pane-clear, pane-border, and explicit translucent chrome colors. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * test(tmux): wait for the main window to adopt the mirror pane before sending keys `RemoteTmuxMirrorPaneInputMappingTests` required `panel.surface.uiWindow != nil` right after selecting the workspace. A manual-I/O mirror pane spawns eagerly in its hidden bootstrap window, which `uiWindow` deliberately excludes, and the main window's portal adopts the pane host only once AppKit and SwiftUI get run-loop time; `waitForLiveSurface` returns immediately for an already-live surface, so the check ran before adoption and the four key-delivery tests failed at line 176. The failure was hidden until the strict app-host gate. Order the harness window front and pump the run loop until the surface and its native view are in that window, as the other hosted-view input suites do, and assert against the harness window instead of any window. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * test(browser): report the refused connection through the navigation delegate `browserPanelRetriesDiscardedRestoreAfterConnectionRefused` waited up to 30s for WebKit to fail a provisional load to a bound-but-unlistened loopback port. On the hosted app-host runners that failure never arrives: the load neither fails nor commits, so the test timed out at line 147 (no "provisional navigation failed" log line appears for it in any shard). Stop the in-flight load and report `NSURLErrorCannotConnectToHost` for the attempted URL through the panel's real navigation delegate, the pattern `BrowserFailedNavigationReloadTests` already uses. The restore bookkeeping, error page, `restore_pending` clearing, and retry policy under test run unchanged and every assertion is kept. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(cloud): scope reserved-workspace cleanup to its pending card and return the bind window PR #13202 (5d616a7f44) imported `CloudMachineWorkspaceAdoptionTests` and `CloudMachineWorkspaceResolutionTests` from the still-open 13141-cloud-vm-workspace branch without the production changes they assert, and its own run skipped the app-host shards, so they landed red: - `NewMachineSheetPresenter.closeReservedWorkspace` closed the whole workspace, which is a no-op for the last tab and discards user panes added next to a creating card. Port the branch behavior: remove only unadopted loading cards owned by the cancelled machine, clear that binding, keep user content, and give a last-tab loading workspace a local anchor first. `MachineCreateCoordinator` passes the created or reconciling machine id so cancelling machine X cannot clear a binding to machine Y (the tests now assert that scoping). - `v2WorkspaceCloudVMBind` now returns `window_id` alongside the workspace refs, as the bind acknowledgement test expects. - The resolution test selected "first" while the fixture's terminal key is "term-first"; use the key so the placement resolves as intended. - `CloudPaneCreationRetryTests` asserted `discarded` synchronously after the projection returned, but the coordinator applies its generation fence behind `CloudOperationContext.withPhase`'s recorder await, which suspends on a cold per-suite process. Settle with bounded yielding before asserting. Runtime behavior change (cancelled Cloud create cleanup); needs dogfood. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(cli): restore deferred socket connection, explicit SSH control options, and Codex stop idle observations Branch commit c8bfb580ba ("fix: repair failures exposed by strict app-host CI", 2026-09-10) made `cmux vm dev|layout|env` finish local validation and dry runs before opening the socket, passed the caller's explicit ssh options into `userConfiguredControlOptions(fromSSHConfigOutput:explicitOptions:)` so a normalized `ControlPersist=0` from `ssh -G` is not mistaken for host customization, and published `idleObserved` for transcript-terminal prior turns before a legacy Codex Stop so the journal drops an obsolete running turn. The branch's later single-parent commit 38b32bb191 reverted `CLI/cmux.swift` to main's version while keeping the stricter fixtures, and PR #12053 landed that inconsistent state; the fixtures (CLIVMDevTests, CLIVMLayoutEnvTests, the SSH sharing tests, and the Codex missed-prompt Stop test) have failed since. Restore the three CLI changes. `SocketClient.configureAuthentication` and `SocketPasswordResolver` already exist on main, and the CmuxFoundation overload landed with the branch. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * test(cli): align CLI integration fixtures with the shipped hook, SSH, and session-list contracts The main copy of `CLINotifyProcessIntegrationRegressionTests` predates several shipped contracts that the lenient app-host gate never enforced and that 38b32bb191 reverted on the issue-2824 branch: Claude hook acks print `{}` (#7963), Codex resume bindings require rollout evidence so fixtures carry a `session_meta` transcript (#10100), SessionStart publishes a binding so `/clear` counts start after the clear, fresh-terminal SSH startup commands are script paths that the support decoder must read, cmux control-path options follow a resolved `ssh -G` (#8308), and `ssh session list` reports the localized "remote state unavailable" summary with `--json` detail (#9971). The missed-prompt Codex Stop test now asserts the restored `agent.idle.observed` for the prior turn. Flagged for review: the three `ssh pty-attach` cases now expect only `workspace.remote.pty_bridge` once the endpoint is established, matching #12726's `preserveLifecycleForRecovery`; if pre-READY bridge failures were meant to keep reconciling, the flag should be set only after READY instead. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * test(workspace): restore the app-host repairs for fork, focus recovery, and shortcut routing Merge 8d33410585 on the issue-2824 branch took main's copy of `cmuxTests/WorkspaceUnitTests.swift` wholesale and discarded the branch's September repairs (c8bfb580ba, c402b9c515, 2127d97afd); PR #12053 then landed without them while the strict gate started counting the failures. Restore them against current production, plus the shortcut-suite fixes: - Fork in a remote workspace: `sshBootstrapArguments` has used `/usr/bin/ssh` since #9114, and agent socket propagation requires a socket that exists on disk (3bf87e3b4d), so bind a real unix socket and expect the absolute path. - Fork Conversation context actions dispatch asynchronously (#7259, #8173); await the fork panel before asserting. - Git branch and pull request updates publish through `sidebarObservationPublisher` since #6226, not `objectWillChange`. - Config sanitization: `addWorkspaceIfActive` rebuilds templates from the font-size lineage since #8543; override the lineage hook instead. - Focus recovery: AppKit focus is authorized only for a registered, selected workspace whose window carries the main-window identity; use the `TerminalPortalTestWorkspace` fixture and the same registration/pump path as `WorkspaceTerminalFocusRecoverySwiftTests`. - Shortcut routing: clear both Cloud defaults after 9c2ba78be4 swapped them; neutralize Ghostty's imported goto_split fallback (⌘] by ANSI keyCode) in the unshifted-symbol test and assert the digit shortcut does not match; wait for the async runtime start before judging keyDown forwarding (skip loudly without a live surface); wait for the portal to mount before the second-Escape check. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(restore): keep a restore identity when the persisted surface id collides Since #13098 (e0e77eb74f), `newTerminalSurfaceOutcome` treats a nil `restoredSurfaceId` as an interactive create and routes it to the selected pane's Cloud source. Session restore passed nil whenever the persisted panel id was still live (duplicate-workspace or restore-into-live), so a legacy managed-Cloud SSH workspace restored into a live manager was turned into a remote tab create: the scaffold panel stayed startup-suppressed with no initial command and `TabManagerSessionSnapshotTests` failed to unwrap it. Mint a fresh UUID on collision instead of nil; it is free by construction, so the restore keeps its identity and the old-to-new remap works as before. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * test(terminal): align snapshot, projection, terminal, and browser fixtures with shipped contracts Stale expectations and fixed-spin timing in app-host suites that the lenient gate never counted: - Cloud-projected panes restore as manual-mirror reservations with a staged remote identity (#12675), not a local placeholder projection. - Restore reuses the persisted runtime id when free (aff0e32e93), so assert liveness rather than a new id; the catalog ignores writes for a Cloud machine without a registered provider (#11877), so register the fixture provider before publishing. - Wheel sync requires an authoritative scrollbar response (bbc3edfae4); the fixture now answers like `AuthoritativeScrollbarSurfaceView`. - Search overlay mount, first-responder focus, runtime creation, and the visibility-restore redraw run through deferred main-actor tasks; wait for them with the class's `waitUntil` helpers instead of fixed run-loop spins. - Owning the socket path lock is definitive (959f38a4c3): a refused inode left by a dead listener is replaced, so the restarted listener accepts. - The split-divider hit band extends `dividerHitExpansion` past the divider (667cc431d9); derive the pass-through boundary from the constant. - Browser page background blends against Ghostty's effective terminal color scheme, which is host dependent; read the same preference the product uses. - Cloud Machines defaults on in dev builds (#12318); pin the toggle off for the default-mode palette contract. - Prepared navigation requests keep the caller's cache policy (#13003). Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * test(browser): align lifecycle, identity, host-view, loopback bridge, and portal rebind tests with shipped contracts Browser app-host suites that the lenient gate never counted: - `BrowserPanelWebViewLifecycleTests`: out-of-range discard delays are rejected to the default (the cmux.json loader relies on the nil), and the panel's own `isLoading` stays true for the indicator floor, so wait for both flags and assert no discard blockers before discarding. - `browserNavigationUsesEmbeddedWebKitIdentity`: WebKit reports the native identity as nil or "" (#9482); accept either. - `WindowBrowserHostViewTests`: production routes Dock-divider hits by yielding to AppKit so the live sidebar tracker receives them (#10902, e2e381825f); the tests asserting the portal owns and forwards the hit were merged red against a design that never shipped. Realign the stale-frame test to the pass-through contract and remove the four own-and-forward tests with their fixtures. **Flagged for review:** if own-and-forward is still wanted, that is a hit-testing product change for its own PR. - `testRemoteWorkspaceRuntimeBridgeAliasesMultipleLoopbackPortsFromSamePage`: the navigation delegate restarts main-frame loads to apply the user-agent policy (11c6efee86); a direct `loadHTMLString` with an HTTP base skipped that step, so the data load was cancelled and replayed as a deferred request. Apply the identity first and assert the document is current. - `portalRebindPreservesDocumentAndRoutesRefreshToTheSameWebView`: the portal host is a theme-frame sibling of `contentView` for non-glass windows (#12929); assert same-window instead of descendant-of-contentView.

Use the class's `waitUntil` for those four sites too. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * test(cli): model surface.respawn for respawn-pane and give the Codex stack fixture rollout evidence `cmux respawn-pane` has sent `surface.respawn` instead of `surface.send_text` since #5465 (8cafcc3bac); the window-flag fixture's mock still rejected that method, so the CLI exited 1. Answer `surface.respawn`, asserting the window and surface ids, `tmux_start_command`, and that the shell-invoked command carries the user command but never the `--window` flag, which is the test's intent. The Codex interrupted-stack fixture's transcript had no `session_meta` line, so `CodexSessionResumeVerifier` (#10100) found no rollout evidence and the prompt published `surface.resume.clear`. Prepend the session line as the other Codex fixtures do. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(socket): keep mobile.panel.artifact.fetch off the local socket and advertise the served artifact reads 02c1ba4dd9 removed `mobile.panel.artifact.fetch` from the socket worker methods because it needs the authenticated mobile execution context, but that half of the change was lost in a merge: the policy still routed fetch to the worker lane, which has no handler for it, so the local socket answered `internal_error` instead of the `method_not_found` boundary that `TerminalControllerSocketSecurityTests` pins. Restore the removal. `system.capabilities` never advertised `mobile.panel.artifact.stat` and `.thumbnail` although both are served on the worker lane (04ff18eea6 added them only to the test's expectation); advertise those two and keep fetch out. The remote relay allowlist is unchanged. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * test(remote): align tmux seed transport, SSH, socket command, and port scanner fixtures with shipped behavior - `RemoteTmuxPaneSeedTransportTests`: manual-I/O mirror panes spawn eagerly (#9272) and stay runtime-backed after portal churn (#9769), so the pane renders its assigned grid before a seed arrives and nothing was retained. Publish a larger tmux pane grid than any test surface applies so the retention under test sees the lag it exists for. - `SSHRemoteCWDRegressionTests`: the persistent-PTY exec helper runs only with `protectsFromHangup: true` (cd9f34ff1b); pass it, and widen the first-spawn guard. - `SSHDeepSleepReattachTests`: a Cloud-owned workspace rejects launch overrides on splits (#13098); create the custom-identity pane before configuring the remote connection. - `SSHConfiguredRemoteCommandHostTests`: ssh-pty-attach validates the bridge `daemon_version` before dialing (#12726); the mock now reports one. - `CloudManualMirrorTransportTests`: the pane failure card uses the short title since 9bf6cb8c94. - `SurfaceSocketCommandTests`: `vm.workspace_new` admits its optimistic workspace through the active main window (#13152, #13155), so bind a bare window to the fixture context; a receipt without a starter terminal costs one snapshot (6d43ea699a). - `PortScannerPublicationTests`: the forced-result acknowledgement hops off the main actor, so an unchanged port set may be deduped under a later refresh; drain publications until the retirement lands.

It never can: OneShotTerminalLauncherStore.enterableWorkingDirectory rejects a path that is not locally enterable, which is what keeps the owning shell valid (#7031). The remote cwd does survive restore — as the panel's trusted remote directory report, and as the `cd` prefix the resume input carries (both already asserted). Assert it where it actually lives and pin the spawn cwd to nil. testSidebarPullRequestsTrackFocusedPanelOnly expected a background panel's PR to be hidden from sidebarPullRequestsInDisplayOrder(). That list is documented as the workspace's deduplicated rows in pane/tab order, both consumers (taskStatusSignals, the control-sidebar snapshot) want every panel, and the sibling branch test asserts the same all-panel model. Focus scoping lives in the `pullRequest` binding, which the test already covers. Renamed to match.

That rule stays. Tests that projected, restored or opened browsers into a made-up workspace ID now failed with destinationNotFound, timed out waiting on a provider that was never called, or passed a later check for the wrong reason. LiveWorkspaceFixture registers real Workspace objects and hands the catalog a CloudWorkspaceRenameService that resolves them, the way the app's composition root does. Its workspaces() list stays empty so the native projection coordinator does not start mirroring into them. For tests on SurfaceCatalog.shared, withAppRegistration registers the TabManager as a windowless main-window context for the test body.

Its last clause only admitted replacing an accepted name when the local panel still carried `.auto` provenance, but since 1e1d319dd1 an accepted daemon name reconciles locally as `.remote` and the owner lives in the tab's nameAuthority. Every agent title after the first accepted one was refused, so "Failed agent rename keeps the accepted title", "Mirroring an agent-named placement does not block its next agent title" and "An older automatic result and old snapshots cannot replace an accepted name" failed on their second agentName call. Admit an automatic rename when no write is pending and the accepted tab name is owned by the daemon's `auto` authority. User-owned names, pending writes and local user titles on any projection still refuse it.

Restore both hunks and drop the duplicate port-less privateDesktopURL overload. Tests: - CloudDisplayCatalogTests: 178d35e5da (#13196) made every guest command run `list` as a readiness probe, so fakes dispatching on " list" answered creation with the list catalog. Dispatch on the create action line, and pin the command shape. - CloudPortOpenRegressionTests: 178d35e5da (#13196) filters RFB/noVNC ports only when the display catalog owns them (displayPortsOwned). Assert both the desktop and non-desktop results. - CloudTreeOneMachineManyWorkspacesTests: #12740 added a final Resources section under each machine. Expected trees include it.

Restore eb3edd7f98's displayResources pools, the display-kind delta check, and the injectable displayCoordinator. Drop the now-unused desktopDisplayResource(). Adds a test that creates display:2 through the provider and asserts that both displays and their ports survive a full publish and a display delta.

When the placement lane drains it reconciles against that graph, which predates the projected tab, and clears tab_projected. The real reply always carries a mutation cursor (CmuxTuiSnapshotParser.placedTab requires one) that fences exactly this; the fake returned none. Give the fake a projectCursor and set it ahead of the installed graph. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test: register the restored window before relinking Cloud projections #13196 made SurfaceCatalog.validateOwnership refuse a destination the app cannot resolve, so SurfaceCatalog.shared no longer relinked a restored projection into a TabManager that no main window owns.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test: wait for the relay ports kick, not the first relay line Since #8442, a relay prompt also reports shell state. Both RPCs run in separate background children, and the zsh prompt-refresh test waited only until the log was non-empty, so it could read report_shell_state alone. Wait (deadline-bounded) for the ports_kick line itself, in the zsh test and its bash sibling. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(cli): relay output of an SSH session that ends right after auth The expect wrapper watches the first two seconds after sending the password for a rejection with log_user 0. A session that authenticates and exits inside that window hit the eof branch and its output was dropped. Flush the buffered output before exiting. #13207 replaced the test's 9 s sleep with a FIFO release, which is what exposed this. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test: restore the no-connection path for rejected vm dev input 4120e35654 taught runVMDev that invalid input never connects: keep the listener open, then check its backlog after the CLI exits. #13207 dropped that again, so each rejected run waited 60 s for a mock-server expectation that only the listener closing (after the wait) fulfills. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test: drain the terminal while the SCP host-key failure runs The pty case read the master only after the CLI exited. A pty's output queue holds about 1 KiB and the host-key failure report is longer, so the CLI blocked writing stderr until the 30 s timeout. Read the master on a thread while the CLI runs. The test starts its own sshd; no runner host dependency is involved. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test: fail fast when a gated Cloud call ends before its fake is entered Every app-host restart in the 09-21/09-22 shard logs I sampled was a Swift Testing time-limit hit in one of two suites, and each hit relaunches the test host: - SurfaceCatalogTests: when catalog.project threw before reaching the provider (destinationNotFound, fixed by 3dc91b2321), each gated test parked in MaterializeGate.waitUntilEntered() until the 300 s limit. Five tests restarted the host one after another, about 25 minutes per shard. - CloudDisplayCatalogTests: when the fake no longer recognized the create command (fixed by 70eaf44819), create() failed before the exec started and `await started.result` parked until the 60 s limit. The waits now also end when the caller's task finishes, so the next such setup failure is an ordinary failed #require. The cancellation test also waits on its own cancellation signal instead of a 60 s Task.sleep. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test: reveal a retired terminal through the portal rebind, as the app does Since #12607 hiding a terminal removes its hosted view from the window, and only a bind reinstalls it. The test flipped portal visibility on the detached view, so no size commit could ever land and the final shrink check failed every run. Rebind like TerminalPortalReconciliation and drop the wait loop. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test: pin key-window status in terminal focus suites The app-host test process runs headless and is usually not the active app, so makeKeyAndOrderFront never makes a programmatic window key. Terminal focus paths gate on isKeyWindow (automatic first-responder apply, focus redraws, deferred focus reapply, ensureFocus window activation), so these suites passed only when an earlier test in the shard had activated the app. Share the existing KeyStatusTestWindow and use it in WorkspaceTerminalFocusRecoveryTests, WorkspaceTerminalFocusRecoverySwiftTests and TerminalNotificationDirectInteractionTests.

A standalone bonsplit replay of the same sequence converges, and a sibling test without a bound (portal-visible) workspace heals the same displacement. Add the live split view's arranged widths and the split model's imposed extent to the failure message so the next run shows whether bonsplit refused the apply, the imposition was cleared, or the portal did not follow.

Activate explicitly, and give the wait a CI-appropriate timeout: the activation and the key-window transition land on later main run-loop turns, and the pump's one-second default expires before the window goes key on a contended runner. Observed on run 35743588302: `plainTerminalTextDoesNotResolveAppShortcutContext` (shard 1/6), `keyboardCopyModeKeyClearsTerminalUnread` and `workspaceFontSizeShortcutPreservesBackgroundTerminalUnread` (shard 2/6) all fail at this helper's return value, and shard 6/6 shows the same process state directly as `NSApp.keyWindow -> nil`. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test: give standalone terminal fixtures a live portal authority `setVisibleInUI` and `setActive` fold their request through `Workspace.portalRenderingEnabled(for:)`, which denies any workspace id the app delegate cannot resolve to a selected tab. Three direct interaction tests build their surface with `tabId: UUID()`, so once any earlier test installs an `AppDelegate.shared` the authority denies the portal, the hosted view is never actually made visible or active, and the fixture stops exercising the behavior it asserts: the surface never takes Ghostty focus and never schedules a visibility-restore redraw. Register a real selected workspace and build the surface with its id, so the fixture gets the same authority the app grants the selected tab. This is the fixture, not the product: the authority check is deliberate, and denying an unresolvable workspace is what keeps queued portal callbacks from reviving an inactive workspace. Fixes on run 35743588302 shard 4/6: `testKeyDownRecoveryDoesNotReplayFocusAfterResponderMovesAway`, `testVisibilityRestoreRefreshesSurfaceWhileTerminalIsInactive`, and `testDirectFirstResponderFocusRefreshesCursorStateAfterForeignResponder`. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * chore: normalize project.pbxproj after merging main Run 35763999808 failed `Fast static checks` before any macOS job could start, so the app-host test fixes on this branch were never exercised: error: cmux.xcodeproj/project.pbxproj is not normalized. Run scripts/normalize-pbxproj.py to fix. The branch head alone checks clean. CI builds the merge of this branch into main, and that merge is what leaves the file unnormalized, so the failure does not reproduce without merging main first. The change is one build-phase entry moving back into alphabetical order. `LiveWorkspaceFixture.swift in Sources` keeps the same UUID and the same occurrence count, and `scripts/lint-pbxproj-test-wiring.sh` still reports ok across 1049 test files, so no target lost a source file. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * perf(tests): stop app-host unit tests waiting out real timeouts The app-host suite spends most of its wall clock in a handful of tests that wait out production timeouts, churn oversized fixtures, or run benchmarks. Each one now drives the same behaviour through an injected timeout, clock, or completion signal, with a separate cheap assertion pinning the default value to the production/server default. Production changes are configuration seams and one real fix: - KeyboardShortcutSettings.resetAll only removes keys that are stored, so a reset no longer fans out one UserDefaults.didChangeNotification per action. - SocketStartupWaiter / AgentRestorePreflightTimeout / BrowserDownloadWaitTimeout own the CLI wait windows (default plus a narrowing environment override), so client and handler cannot drift apart. - PortScanner and BrowserScreenshotWebViewSnapshotter take their schedules as parameters instead of hardcoding them. Benchmarks move out of the app-host unit suite behind the existing gating pattern, keeping their correctness assertions in the unit suite. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix: keep the scroll settle default readable from a nonisolated context The default lives on a @MainActor enum, so every default-argument use of it is evaluated in a nonisolated context and trips the Swift 6 isolation warning. The value is an immutable Sendable constant, so mark it nonisolated rather than isolating four call sites. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(tests): stop kicking the port scanner from the poll loop Review found two defects in the slow-test pass. 1. `PortScannerPortRetirementTests` polled every 25ms and called `scanner.kick()` on every poll, against the 10ms compressed coalesce delay this PR introduced. `kick()` calls `startCoalesce()` whenever no burst is running, and `startCoalesce()` cancels and re-arms the timer. On a loaded runner the timer's jitter is the same order as the coalesce window, so the kick burst can cancel the timer indefinitely: no scan ever runs and the test burns its 20s deadline. The previous 500ms poll against a 200ms delay left a 2.5x margin that the compressed schedule removed. Fixed by removing the kick from the poll loop rather than by widening the interval, so the speed win stays and the flake vector is gone instead of made less likely. A kick already guarantees `minimumScansPerKick` scans - exactly the complete misses the reconciler needs to retire a port - so one kick after `stopListening()` is sufficient. That is the shape `lateBurstKickRetiresStoppedListener` already used. `onKick` is gone from `waitForPublication` entirely, so the poll interval is no longer coupled to the coalesce delay and the footgun cannot come back. 2. `scripts/test-command-palette-nucleo-ffi.sh` set `CMUX_COMMAND_PALETTE_SEARCH_BENCHMARKS=1` and then passed `-only-testing:cmuxTests/CommandPaletteNucleoFFITests`, a different class from the four `CommandPaletteSearchEngineTests` benchmarks this PR gated behind that variable, so those four ran nowhere. The script now names both classes and asserts one BENCH line per gated benchmark, since a skipped benchmark otherwise passes silently. Nothing referenced the script either, so even the FFI tests it names were not run by CI. `.github/workflows/command-palette-search-benchmarks.yml` is its scheduled caller, modelled on the `tmux-corpus.yml` nightly (same checkout/GhosttyKit/zig/rust/SPM-cache setup, same `cmux-unit` scheme). The script takes an optional `CMUX_NUCLEO_FFI_SOURCE_PACKAGES` so the workflow can reuse the cached package clone. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * ci: keep the benchmark caller dispatch-only while automatic CI is paused tmux-corpus.yml and perf-activation.yml -- the two closest macOS benchmark nightlies -- both carry "Temporarily manual-only beginning 2026-07-13 to pause automatic CI" and have their crons removed. Adding a live cron here would quietly reverse that reduction, which is the opposite of what this branch is for. The gate still has a caller, and the script's BENCH assertions still fail the job if a gated benchmark silently skips; running it is now a deliberate act rather than a daily cost. Drop "nightly" from the name, since it is not one. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(tests): model the title-word ranking term in the search reference testBenchmarkCorporaMatchReferencePipelineOnSmallFixture asserts the optimized engine equals a reference pipeline rebuilt in the test. On the query "workspace 31" the engine scored workspace.large.31 at 17598 and the reference at 16000, so the suite failed. The engine ranks on three terms; the reference modelled two. The missing one is commandPaletteTitleWordScore: a query that is, or prefixes, a title's search words scores the tokens' upper bounds plus a per-token title bonus. For "workspace 31" that is 6799 + 6799 + 2000*2 = 17598, exactly the observed gap. The reference now models that term too, reimplemented rather than calling the engine's copy, because a reference that shared the implementation would assert nothing about it. FixtureEntry prepares the two title texts the term needs once at construction, so the benchmark timing loops — which build fixtures outside the timed region — do not start charging the legacy side for preparation the engine does not repeat either. Verified by compiling the engine sources against this reference on Linux and comparing all 34 corpus/query pairs the parity tests use: the large benchmark corpus goes from 1 mismatch to 0, and the command, switcher and switcher-benchmark corpora stay at 0. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(tests): drop the ineffective SSH auth retry budget rewrite persistentAttachExitsAtForegroundAuthenticationFailureLimit() rewrote the generated startup script to shrink the 20-failure foreground-authentication budget to 3, then asserted 3 attempts. CI recorded 20: the rewrite never changed the behaviour it was meant to bound. The budget the test edited lives in the shell wrapper, but the preserved __ssh-* CLI helper is what owns authentication retries and counts them itself, so rewriting the wrapper's literal leaves the helper executing its own 20. The shrink was decoration over a real 20-attempt run. The test now keeps the production budget and asserts 20. The fake sleep already removes the backoff between attempts, which is where the wall-clock cost actually was, so the same failing run reached the assertion in 4.25 s against the 6.1 s this test cost before the PR. That is less than the <1 s the PR's table claims for this row; the table is corrected in the PR body. replacingWithinScript, scriptDecodeLevels and applyingReplacements existed only for this rewrite and have no other callers, so they go with it. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(tests): close the persistent CLI client before awaiting the mock testDefaultFreestyleSSHAttachHidesPersistentRetryLimitInCountdown failed with "Asynchronous wait failed: Exceeded timeout of 5 seconds, with unfulfilled expectations: cli mock socket handled", after 5.227 s. startMockServer fulfills once the first connection is done. This test drives a persistent SSH attach, so the client holds its connection open across the retry countdown and the mock has no "done" to observe. The wait could only ever end by timing out; it had been passing on the longer window this PR narrowed. The test now terminates the child once it has observed the progress it actually asserts — the "Retrying in 0.1s (attempt 2)." banner — and waits for the mock afterwards. The countdown assertions that follow are unchanged and still read the captured output. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * Retrigger CI after retargeting this PR onto main The synchronize event that pushed ed3ab7a61e fired while the base was fix/app-host-green, a branch the #13643 squash merge had already deleted, so GitHub could not build the merge ref and the pull_request CI workflow never started. Only the two pull_request_target workflows ran, which left the required ci-status check absent rather than red. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * Make the two new timeout holders instantiable values CI's iOS conventions guard reported two violations this branch introduced: AgentRestorePreflightTimeout and BrowserDownloadWaitTimeout were both caseless enums with an all-static public surface, which the lint refuses because such a type can never be substituted. The refusal is right, and for this branch in particular: the point of the change is that a test should be able to hold a timeout agreement without spending it. A static holder cannot be narrowed, so the tests could only assert the shipped numbers. The restore preflight budget moves onto AgentRestorePreflightInvocation, which is the type it bounds and already carries the environment it is read from. Names lose the now-redundant prefix: defaultSeconds becomes defaultTimeoutSeconds, environmentKey becomes timeoutEnvironmentKey, and seconds(environment:) becomes timeoutSeconds(environment:). BrowserDownloadWaitTimeout becomes a struct whose three windows are stored properties with the shipped values as init defaults, plus a `standard` value the handler and the CLI client both read. Both call sites take `.standard`; the behaviour is unchanged. The regression test now also constructs a narrow window and asserts the client still outwaits the handler, which makes the invariant a property of the pair rather than an assertion about 10 seconds. Verified with swiftc 6.1.3 on Linux: both files type-check under -swift-version 6, and the extracted behaviour matches the previous constants exactly (10s default, 10s ceiling on the override, whitespace trimmed, non-finite and non-positive overrides ignored; 10000ms default window, 120000ms cap, 15.0s client response timeout). The conventions diff lint now reports no new violations.

Neither file is touched by this branch. The cause is cmuxTests/AppDelegateMainWindowTestingSupport.swift, where the merge of main kept both sides' addition of the same class: `final class KeyStatusTestWindow` appeared twice, byte-identical including its doc comment, so every construction of it was ambiguous. Git had no conflict to report — the two additions did not overlap — which is the third time on this branch that a clean automerge produced code that could not compile. Checked the rest of the merge for the same shape: no other duplicated top-level type in cmuxTests, and none in CLI/ or Sources/. The one other repeated name, `optimizedResults` in CommandPaletteNucleoFixtures.swift, is a legitimate pair of overloads taking `corpus:` and `entries:`. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test: expect the reconnect budget #13959 honors, not the old clamp The new budget probe asserted that "21" and "021" clamp to 20. Main's #13959 made a well-formed budget above 20 honored up to SSHReconnectBudget's ceiling, so the merge ran green through git and red on CI: stdout "21". The cases now carry their expected value, from SSHReconnectBudget where it is a policy constant. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * ci: gate the benchmark runner behind the paid-overflow switch Main's #13994 guard rejects a vars.MACOS_RUNNER_15 read without CI_PAID_MACOS_OVERFLOW, since it can hold a metered WarpBuild label. This branch's new benchmark workflow predates the guard, so the merge of main passed git and failed workflow-guard-tests. Same form as perf-activation.yml. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * test: close CodeRabbit gaps in the fast app-host test rewrites - PortScanner late-burst: the runner stops listening and issues the late kick from inside the fifth lsof call, instead of the test task racing a one-second timer gap it could miss in either direction. - Sidebar quiescence: the quiet window is measured in time and spans twice the sidebar's 50ms coalesce stage, so a pending coalesced or debounced row invalidation cannot land after the drain declared quiet. - SSH exit prompt: waitUntilBlocked samples the launched process and all of its descendants, so it holds whether the shell execs the startup script in place or forks it; terminate() retires that tree so a forked, parked helper cannot hold the output pipes or leak into the test host. - Sidebar git refresh: wait until the panel is a poll candidate again before each refresh; a completed read can precede the probe clearing. - Diff fixtures pin SHA-1 objects and loose-file refs, which the handwritten refs and in-process blob ids assume. - Rename the registry test to the post-list enrollment order and assert it. - TerminalController uses BrowserDownloadWaitTimeout's shared clamp.

The polling test was then rewritten to assert that slower order. Neither change is part of this PR, and #13403 carries the same removal for its owner to argue. Both files now match main, whose test asserts the prewarm starts before fleet discovery finishes.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix: report browser.download.wait's requested timeout as a number again The shared timeout window left requested_timeout_ms an Optional, which the timeout error payload coerced to Any and which put a new warning over the Swift warning budget. The handler resolves the default and the lower bound before clamping, as it did before, so the field is the same Int as before. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * test: settle the Global Search palette before each routing test KeyboardShortcutSettings.resetAll() no longer posts one UserDefaults.didChangeNotification per action, so the next test's init no longer spends enough main-thread time for the previous test's animated NSPopover close to finish. Two routing tests then saw isShown == true from the palette an earlier test had opened (run 35967763918, shard 7). Dismiss the palette and pump the run loop until it closes, bounded at 2 s, in both suites' init, matching the helper the sibling suites already use. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * ci: route the palette benchmark workflow to a hosted runner on forks main's fork runner routing guard (test_ci_fork_runner_routing.py) now rejects a runs-on expression that can reach a Blacksmith label outside manaflow-ai. Lead with the owner fork branch, as perf-activation.yml does. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * ci: drop the extra paren in the palette benchmark runs-on expression 572dc2a3aa7 kept the old closing paren and added another, so actionlint could not parse the expression. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * ci: set up Bun on the shard that runs agent notification semantics The notification semantics step resolves `bun` with `command -v bun`, but Bun was only set up on the CLI regression shard (4) while the step runs on the focused regression shard (6). Main never reaches the step because its unit batch fails first, so the missing Bun only shows once shard 6's unit tests pass, as they do on this PR. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * test: scope the CmuxWebView keyDown hook to each reentry test CmuxWebViewKeyDownReentryTests swizzled CmuxWebView.keyDown(with:) for the rest of the process. When CmuxWebViewWebContentUndoTests ran after it in the same app host, browserCmdZPerformsWebContentUndoWhenPageDeclinesTheChord recursed in the test hook until the stack overflowed (seen on macOS 15 and 26 once this PR's shard layout put the two suites back to back). Install the hook per test window, call the captured original implementation directly instead of re-dispatching through a swapped selector, and restore the original implementation when the window closes. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * test: keep the OpenCode feed harness socket inside sun_path testOpenCodeFeedPluginEmitsCompletionForBothIdleEventShapes put its Unix socket under FileManager.temporaryDirectory plus a UUID-named root. On a Blacksmith runner that is /private/var/folders/.../T/, and the path runs past the 104-byte sun_path limit, so the Bun harness fails in listen() and prints nothing. Use a short /tmp path for the socket instead. This surfaced once the agent notification semantics step ran on this PR; main never reaches the step because its shard 6 unit batch fails first. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * test: wait for the relayed pwd line, not the first relay line zshRelayPromptReportsRemotePWD broke out of its wait as soon as the relay log was non-empty. _cmux_precmd sends report_shell_state and report_pwd as separate background relay calls, so on a busy runner the log held only the shell-state line when the test read it. Wait for the report_pwd line itself, up to 5 s. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * test: tie the E2E stale-snapshot case to OWNED_MAX_AGE_MINUTES #14341 raised OWNED_MAX_AGE_MINUTES from 20 to 45, so a 30 minute old snapshot is now fresh enough and the "snapshot too old" case in test_run_e2e takes the owned Mac, failing app-host-execution guards. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> (cherry picked from commit 3dfc85f17f2b54936fb044ee718387b2f4258903) * test: pin the full paste worker to lossy rich text, per #14121 #14121 sends mixed rich and plain text through the plain-text helper, so richPasteDoesNotUsePlainTextHelper (HTML plus a clean plain string) now gets a successful fast-path paste instead of the full worker's error, and it has failed on every main run since. The helper still declines rich text whose plain export lost characters (U+FFFD or repeated '?'), because the full worker can recover them. Assert that case instead.

Summary
Addresses #12904. Accepting New Machine reserves a local workspace and pending machine row before launching the create. All native New Machine entrypoints use the shared coordinator. Background completion preserves selection and focus.
Consolidates #12911. This branch carries the full history of "Cloud startup latency: measured baseline, lower bound, and benchmarks" (merge commit
a64d338a2d9oforigin/pr-12911):docs/cloud-startup-latency.md, the raw run artifacts underdocs/cloud-startup-latency/, the three benchmarks underweb/scripts/cloud-vm/, andweb/tests/cloud-vm-bench-stats.test.ts. #12911 is closed as superseded; its description remains the reference for those deliverables. Create-time naming (vm.createcarriesdisplay_name; older backends keep the rename fallback) and the Blacksmith-published cmux-tui client reuse inreload-build.ymlcome from the same lineage.Merged
