test: stop tests waiting out real timeouts - #15381

Conversation
Tests that only end when a production timeout, drain bound, poll interval or retry delay expires now pass a short value. Every timeout stays injectable with the production default unchanged, and no assertion changes. - CloudMachineLinkManager takes the private-route CloudHubConnector; the failed dual-stack probe test passes a 1 s connect deadline (15 s). - The refused CONNECT test gives CloudPortForwardRelay a 1 s handshake timeout (15 s). - TerminalCustomUploadRunner.spawnCommand takes the pipe drain bound. - CloudTelemetryUploader takes its batch delay. - AgentForkSupport.supportsFork takes the probe output timeout. - The CLI reads CMUX_VM_WAIT_POLL_SECONDS and CMUX_VM_LAYOUT_OPEN_RETRY_DELAY_SECONDS. - drainMainQueue takes its timeout. A @mainactor Swift Testing body runs inside a main queue block, so the main queue cannot drain and each call spun for the full second; those suites spin for 0.1 s.

Subagent review at d464890 (70b0c5a adds a one-line pacing fix and a main merge): approve with nits, nothing blocking. Findings: production defaults match the old hardcoded values (hub connector 15 s, telemetry batch 2 s, fork probe 3 s, upload drain 2 s, vm layout retry 1 s and vm ready poll 3 s with fallback on bad input). The CloudMachineLinkManager init change only adds a defaulted trailing parameter, and no call site breaks. No test passes vacuously. Nits, not addressed: the final vm wait sleep is now clamped to the deadline (slightly tighter --timeout); the two env overrides are honored in release CLI builds (they can only shorten waits); testVMWaitBoundsOversizedPollIntervalToCommandDeadline uses a CLI timeout equal to the harness timeout; the savings table in the description predates the later 2 s values. Auto-merge on. |

- Around line 631-635: Update the oversized-interval assertion to test
vmReadyPollInterval(environment:) directly instead of launching the CLI with an
eight-second timeout; keep the process-level polling check on the existing short
valid override.
Review comments at @cmuxTests/CloudLoopbackPortForwardTests.swift:
- Line 268: Replace real-time deadline waits with manual-clock control in both
affected tests: in cmuxTests/CloudLoopbackPortForwardTests.swift lines 268-268,
inject SidebarTestManualClock into CloudPortForwardRelay and advance it to
trigger the handshake deadline; in
cmuxTests/CloudPrivateRouteSelectionTests.swift lines 150-150, inject and
advance a manual clock to trigger the connector deadline. Ensure neither test
depends on wall-clock time.
Review comments at @cmuxTests/TabManagerUnitTests.swift:
- Line 29: Replace the timeout-based drain in drainMainQueue with a completion
signal owned by the close or history operation; update one affected test to
await that signal before asserting state, then migrate the remaining callers to
the same action path.
Review comments at @cmuxTests/WorkspaceSSHFishProcessDrainTests.swift:
- Line 29: Update the `runProcess` flow so the shell’s `ready` signal is
observed before starting the two-second kill deadline. Use readiness as the
synchronization point, then preserve the existing kill-path assertions so
startup latency cannot consume the test’s deadline.

…ompiles #15381 asserted `CMUXCLI.vmReadyPollInterval(environment:)` from the app-hosted CLIVMTransferTests, but in cmuxTests `CMUXCLI` is `typealias CMUXCLI = CmuxTuiRemoteRouting` (the app's routing enum), and the helper exists only in the CLI target. Since #15946 landed the helper, every cmuxTests build on main fails: cmuxTests/CLIVMTransferTests.swift:730:21: error: type 'CMUXCLI' (aka 'CmuxTuiRemoteRouting') has no member 'vmReadyPollInterval' The pure override policy now has its own cmuxCLITests suite, which imports the CLI and covers every branch (valid, missing, oversized, zero, negative, NaN, non-numeric). The process-level test in CLIVMTransferTests keeps its short valid override. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> (cherry picked from commit 90851e5)

- CLIVMTransferTests called CMUXCLI.vmReadyPollInterval, but cmuxTests aliases CMUXCLI to CmuxTuiRemoteRouting and does not link the CLI. The parser contract moves to a cmuxCLITests suite that imports cmux_cli; the process-level vm wait check stays in cmuxTests. - #15381 switched callers to drainMainQueue(timeout:) without changing the shared helper; the helper now takes the timeout (default 1 s). - #15420 dropped the `controller` binding PaneResizeShortcutTests still uses; restore it with the post-settle 1000-point container. - CloudWorkspaceReconcileBudget.admit is mutating, which #expect cannot call on its captured copy; record each result before asserting.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Mark the manual pull request transition helper discardable The manualPullRequest setter ignores whether the value changed, which the compiler reports as an unused result and the Swift warning budget rejects.

The two tests now seed the hook state file, run a real `cmux hooks claude session-start` against a mock socket, and read what the CLI left on disk, like the rest of cmuxCLITests: - a malformed sibling record no longer discards a valid session mapping, and a salvageable file is not quarantined; - each of two unreadable state files is moved to its own quarantine backup with its original bytes, and the store keeps working afterwards.

* Add failing regression test for discarded browser pane page state A hidden browser pane discarded for memory comes back through a fresh URL navigation, so it loses native back/forward history, scroll position and typed form input (#15069). This test discards a scrolled page with typed input and asserts all three survive the restore. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Restore discarded browser panes from WebKit session state Discarding a hidden browser pane kept only its URL, history URL list and zoom, so returning to it replayed a fresh navigation: scroll position, typed input and SPA route were lost (#15069). Discard now captures the page's WebKit interactionState, a snapshot image and the typed form values reported by an isolated-world user script. Restore assigns the interaction state to the replacement web view, paints the snapshot with a "Restoring" label until the first paint, and replays form values once the document loads. URL replay stays as the fallback when no state was captured, the state belongs to another document, or WebKit does not start a load from it. Interaction state is persisted in session snapshots so relaunch restores the same way, except for private profiles, form submissions and state over the size limit. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Add failing regression test for hidden WebContent termination restore A WebContent process that dies while its browser pane is hidden leaves the pane behind the manual Reload overlay, and recovery reloads the URL (#15069). These tests expect revealing the pane to restore the last session state instead, including when an uncommitted load was in flight at termination. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Restore hidden panes whose WebContent process died from session state A WebContent process that terminates while its pane is hidden no longer parks the pane behind the manual Reload overlay. The termination records that the pane was hidden; showing it converts the dead view into a discarded one and restores the WebKit interaction state, so history, scroll and form input come back without a URL reload. A load that had not committed when the process died restores the committed page instead. A crash while the pane is visible keeps the Reload overlay so a page that crashes its own process cannot reload in a loop. Refs #15069 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Add failing regression test for timer-free hidden web view discard default Issue #15069 asks for Chrome-style tab discard: a hidden pane keeps its page until hidden web content exceeds a memory budget, and the fixed hidden-time timer becomes opt-in. Today an idle pane hidden past the delay is discarded by the default policy. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Discard hidden web views oldest-first under a memory budget Hidden browser panes used to be discarded by a fixed timer. The default policy is now a hidden WebContent memory budget (browser.hiddenWebViewMemoryBudgetMB, default 2048). On each memory sample, BrowserHiddenWebViewMemoryBudgetCoordinator evicts the pane that has been hidden longest until the total fits. The timer is still available as browser.hiddenWebViewDiscardMode = "timer". The memory-pressure responder is unchanged. The mode and budget are wired through CmuxSettings, Settings > Browser, the cmux.json schema and the settings file, with localized strings. Refs #15069 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Add failing regression test for hidden pane discard blockers Issue #15069 asks the memory budget to leave alone a hidden pane whose state a restore cannot bring back. Typed input the restore never replays, such as a password or a rich-text editor, should keep the pane until the system is under memory pressure. Picture in Picture should keep it alive like playing media. Today the budget discards all three. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Keep hidden panes whose state a restore would lose The hidden memory budget could discard a pane holding typed input the form restore never replays (a password, a rich-text edit), close a page's Picture in Picture window, or drop a screen share. Those now block a routine discard: - The form-state observer flags unrestorable input, including values dropped by the capture caps, and the pane re-evaluates its discard schedule when that flag changes. System memory pressure still frees such a pane. - The media hook reports Picture in Picture per frame, and a paused Picture in Picture video keeps the pane alive. - Display and system-audio capture count as media capture next to camera and microphone. An explicit urgency (routine or system memory pressure) replaces the boolean that let pressure override a recoverable WebContent termination, so every pressure-only bypass reads from one place.

Refs #15069 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Add a per-pane pin that keeps a hidden browser page active "Keep Page Active While Hidden" in the command palette pins the focused browser pane. A pinned page is never discarded while hidden, not even under system memory pressure, and the pin survives relaunch through the session snapshot. Toggling it re-evaluates the pane's discard schedule. Refs #15069 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Add failing regression tests for manual restore of unloaded pages With browser.autoRestoreUnloadedPages off (#9561), showing a discarded pane, or one whose WebContent process died while hidden, must leave it unloaded until the user restores it, and that restore must still bring back history, scroll and typed input. Refs #15069 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Add a setting to keep unloaded browser pages until the user restores them browser.autoRestoreUnloadedPages (default true) decides whether a page unloaded to save memory, or whose WebContent process ended while hidden, restores as soon as its pane is shown. With it off, the pane keeps the page's last snapshot, dimmed, with a Restore button. Restore brings back history, scroll position and typed input from the captured interaction state, like the automatic path. This is the placeholder #9561 asked for, on the same restore path instead of a separate reload. A relaunched pane's deferred first load never waits, since nothing was unloaded. The page recovery overlay now owns both the crashed-page Reload prompt and the unloaded-page placeholder. The setting is in Settings > Browser, cmux.json and the settings file, with strings in all nine locales. Refs #15069 Refs #9561 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Add failing regression tests for discard restore gaps from review Covers four gaps in the #15069 restore path: - a form-submission result page restored from session state resubmits the form, so it must replay by URL; - a WebContent process that dies while hidden after Stop is not restored; - a back/forward cache return never reports typed input again; - Dock browser panes are left out of the memory budget. Refs #15069 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Restore form submission results by URL and report input after a cache return Assigning session state for a document that came from a form submission, in the main frame or a subframe, makes WebKit send the form again. The restoration state now tracks form submissions per document: a main-frame request sets the pending document's mark and a redirect re-decides it, a subframe submission marks the live document, and a commit moves the pending mark to the live one. A capture whose document is marked replays by URL. A back/forward cache return commits natively, which clears the pane's copy of typed input. The form state script now reports again on a persisted pageshow. Live session state is persisted only while its current entry is the URL the session snapshot saves, since a relaunch restores it for that URL. Refs #15069 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Restore a page whose process died while hidden even after Stop Stop keeps a live page from reloading, but a WebContent process that died while the pane was hidden left no live page to keep. Drop the terminated web view before the Stop check, which clears Stop, so showing the pane restores the page. Refs #15069 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Count Dock browser panes in the hidden page budget and pressure sweep The budget coordinator and the memory-pressure responder walked only workspace panes, so hidden Dock browsers never counted or unloaded. Both now use one app-wide enumeration that covers workspace panes, workspace Docks and window Docks, which also replaces the separate list the detached inspector routing kept. The per-manager and per-workspace pressure helpers go away. Refs #15069 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Create the Dock budget test's workspace through addWorkspaceIfActive The deprecated addWorkspace call added a test-target warning. Refs #15069 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Add a failing test for a new-window request clearing a form submission mark A request with no target frame loads in another web view, but the pane counted it as its own main-frame request. A new-window GET landing between a POST's decision and its commit cleared the pending mark, so a discard of the submission result page restored it with interaction state and sent the form again. Refs #15069 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Ignore new-window requests when tracking form submissions A navigation request with no target frame opens a new window, so its method says nothing about this pane's documents. Treating it as a main-frame request let a GET new-window request clear the mark set by a pending POST, and a POST new-window request mark a page that never submitted a form. Refs #15069 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Splice Memory Saver search entries with a call instead of + After merging main, `[...] + browserMemorySaverEntries + [...]` in cmuxDefault(catalog:) no longer type-checks in reasonable time. Pass both literals to a function, as appendingDevicesEntries(to:) does, so each keeps a concrete contextual type. Refs #15069 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Move the form-state scripts onto the WebKit types that run them The package conventions lint rejects BrowserFormStateScript, an enum with only static members. The content world, observer script, handler registration and restore call are now extensions on WKContentWorld, WKUserScript, WKUserContentController and WKWebView, so BrowserPanel no longer holds the content world or the handler name. The JavaScript is unchanged. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Add failing tests for a browser view outside a window marking its pane visible SwiftUI can build a browser view whose host never reaches a window and then dismantle it. Its visible report leaves a hidden pane marked visible, so Memory Saver never discards it (#15069). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Report a browser pane visible only while its view is in a window SwiftUI can build a browser panel view or portal host that never enters a window and then dismantle it. Its visible report left a hidden pane marked visible, so Memory Saver never discarded it (#15069). Visible reports from the panel view and the portal lifecycle now require the view to be in a window, and each reports visible when it enters one. Hidden reports are unchanged. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Let the window visibility tests run main-actor tasks The tests ran synchronously as a main-actor job, so the nested run loop never ran the main-actor tasks that report a panel visible: the portal lifecycle update and the window-entry report. The "outside a window" checks passed without those tasks running, and the "enters a window" checks failed. The tests are now async and yield after each settle pass, as SidebarScrollViewConfiguratorTests does. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Cover popup page-state reports and a remote pane's queued restore A popup built from the opener's configuration shares its content controller, so its form and media reports reach the opener's handlers and replace the opener's typed input or keep it from being discarded. A remote pane whose proxy is reconnecting queues the URL replay; when the queued load starts it clears the in-flight restore that was noted up front, so the typed input never comes back. Refs #15069 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Bind page-state reports to their web view and note queued restores The form-state and media-playback handlers now drop reports from any other web view. A popup shares the opener's content controller, so its reports used to replace the opener's typed input and could keep the opener from being discarded after the popup closed. A URL-replay restore notes itself once its load starts. A remote pane queues that load until its proxy is back, and the queued load's start cleared the restore noted up front, so the typed input never came back. Budget enforcement returns before the per-pane checks when no pane is hidden. Refs #15069 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Wait on causes, not intervals, in the discard and visibility tests The restore fixture waits for both typed values to be reported, the blocker tests wait for the form-state report or its unrestorable flag, and the visibility tests wait for the host or window-presence view before checking that no visible report arrived. Refs #15069 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Wait for WebKit to save the scroll before discarding in the restore tests WebKit saves a page's scroll position into its history item 300 ms after scrolling stops, and the discard restore replays that item. Waiting for the typed-input report, which is debounced from before the scroll, let the test discard first, so the restore brought back the unscrolled position. Wait until the scroll shows up in the web view's session history instead. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Keep the Import Choose… button's accessibility identifier The Import Browser Data block put identifiers on its actions row and on the whole block, neither of which was an accessibility element. SwiftUI applies a container's identifier to the children of such a container, so the Choose… button lost `SettingsBrowserImportChooseButton` and `testImportChooseButtonOpensImportWizard` could not find it. Both containers now contain their children, the pattern the right sidebar tab rows already use. Red: SettingsBrowserBehaviorUITests.testImportChooseButtonOpensImportWizard fails at d192505 in E2E runs 36427228637 and 36430175176. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * test: cover agent commands on hidden panes that need a restore A hidden pane whose WebContent process died keeps a dead web view, so a browser automation command waits for a document that never commits and times out until the user shows the pane. A pane an agent is driving also stays the memory budget's first pick because only hiding counts as use. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix: restore hidden browser panes for agent commands A browser pane whose WebContent process died while hidden kept the dead web view until someone showed the pane. Socket commands captured that view, and their document-readiness wait could never see a commit, so they timed out. The resolver now turns such a pane into a discarded one before the command captures its web view, the way showing the pane does, and the readiness wait restores it from its interaction state without showing it. A command also counts as use of the pane: hidden-pane discards measure the delay from the later of the hide and the last command, and the memory budget evicts by that time, so it no longer frees a page an agent is driving. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * test: record the backdated hide in the agent budget test The workspace can record a new pane hidden before the test backdates the hide, and a repeated hidden report keeps the first hide time. Show the pane first so the backdated hide is always recorded. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Test that agent-driven restore cycles free dropped web views An agent that keeps waking a hidden pane must not grow memory: each discard has to release the web view it drops so its WebContent process can exit, the restored page must fall back under the memory budget once idle, and the captured page state must be freed when the restore commits. Also cover the web view whose process died while hidden.

Point both at main's commits. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Restore Memory Saver settings rows dropped by a main merge Merging main took main's BrowserSection and curated search entries, which brought back the old toggle and delay rows and orphaned BrowserMemorySaverSettingsRows and insertingBrowserMemorySaverEntries. Mode, budget and auto-restore had no Settings UI, and search results for them pointed at missing rows. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Test that every Browser Memory Saver row is searchable A main merge took main's curated settings entries and dropped the mode, budget and auto-restore rows. Against those entries this test fails for Memory Saver Mode, Hidden Tab Memory Budget and Restore Unloaded Pages; it passes with 36efe7a. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Test that imported sessions drop WebKit page state SessionSnapshotImportTrust.sanitizedBrowserPanel filters imported history to http(s) but keeps interactionState, whose own back/forward list would restore the entries the filter removed.

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * fix(web): restore the seats-follow-membership copy the dashboard port dropped The Team subscription quantity follows the member count, so an over-seat line has nothing for an admin to act on: the reconciler updates Stripe on the next membership fact. That was settled in 06f4a7c, which reworded the line in all 20 locales, removed the add-seats link beside it, and dropped the members-page seat nudge. The dashboard SPA port rebuilt the billing panel from the pre-06f4a7c version at a new path, so git saw no conflict and the link came back, and the locale files went back to the soft-seat wording. `web/tests/ dashboard-billing-screen.test.tsx` has been red on main ever since, which fails the required `ci-status` on every web pull request. Restores the wording and drops the link. `seatNudge` and `seatNudgeAction` go too: the nudge they belonged to is gone from the members page and nothing reads them. `docs/team-settings-and-invites.md` already records the rule, and the stale "seats are soft" comment left hanging over an unrelated type in `team-members.tsx` is removed. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * test(web): pin the new-team seat copy too The same merge-resolution path that reverted the billing panel's copy also reverted this line, and nothing asserted on it. Pin the sentence and the old wording's absence so a stale merge side fails the shard instead of shipping. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * fix(dev): apply concurrent-index migrations outside transactions The GCP development backend runs migrations on startup, but drizzle-kit wraps every migration in a transaction and PostgreSQL rejects CREATE INDEX CONCURRENTLY. Share a local migration runner between bun db:migrate, DB tests, and the tagged backend so startup can complete safely while preserving atomic transactions for ordinary migrations. * fix(ci): use transaction-safe migrations and restore queue timeout helper The web migration lane must use the local runner for CREATE INDEX CONCURRENTLY migrations, and the latest main branch's tests still call the removed drainMainQueue(timeout:) overload. Keep both migration passes safe and preserve the timeout-aware test helper for existing suites. * Fix pinned request uploads on Bun 1.3 * fix(ci): route every local migration lane through safe runner * Cancel pinned uploads when requests close * fix(web): insert a real JSON null in the malformed cleanup-row test "Cloud VM database schema > rejects malformed transferred cleanup rows" (#15423) never ran on main, because main's migrations failed before the database behavior tests. With migrations fixed it fails: expect((insertError)?.code).toBe("23514") Expected: "23514" Received: "23502" Its first malformed value is `null`, and postgres.js binds `sql.json(null)` as SQL NULL. The NOT NULL column rejects that (23502) before the check constraint the test is about. The row under test is a JSON null document, so that case now inserts `'null'::jsonb`, and the check rejects it with 23514 like the other nine. Checked on a scratch Postgres 14 with postgres.js: sql.json(null) gives 23502, the JSON null gives 23514, all ten malformed values give 23514, and {modelPlane: true} and {homeVolume: "v"} are accepted. Refs #15488 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * cloud: pin the team date wire shapes in a test The team API writes every date with `Date.toISOString()`, so the strings on the wire always carry milliseconds. This test decodes that shape, the whole-second shape, and a non-date string, and fails today because `TeamsClient.decoder` uses `.iso8601`, which rejects fractional seconds. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * cloud: accept the team API's millisecond timestamps `TeamsClient.decoder` used `.iso8601`, which rejects fractional seconds, while every team date on the wire comes from `Date.toISOString()` and so always carries milliseconds. Team detail, sent invitations, received invitations and invite links therefore could not decode at all, and `macos / swift-package-tests` is red on main because of it. Parse the fractional-second shape first and fall back to whole seconds, matching `VMClient.dateValue` in the same package. `Date.ISO8601FormatStyle` is Sendable, unlike `ISO8601DateFormatter`, so it can live on the static decoder. A string that is not a date still fails. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * test(cloud): pin sub-second precision and a dated invite link A review pointed out that every fixture date sits on a whole second, so a decoder that parses the milliseconds and then throws them away passed the whole suite. Verified on Linux: a truncating decoder now fails. Also covers `CloudTeamInviteLink.expiresAt` as a string, which was only ever null in the fixture, and guards the whole-second replacement against silently becoming a no-op. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * Keep queue helper within test file budget * Avoid duplicate SessionEntry test target source * fix(tests): call the mutating reconcile budget outside #expect #16158's budget test passes budget.admit(...) straight to #expect. Xcode 26.3's macro expands the argument inside a closure where budget is immutable ("cannot use mutating member on immutable value"), so the macOS 15 lane fails at TEST BUILD. Bind each result first. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * test: check the vm ready poll interval in cmuxCLITests The same change as #16242 (90851e5), carried so this PR can restore main's cmuxTests build in one piece. #15381 called CMUXCLI.vmReadyPollInterval from the app-hosted CLIVMTransferTests, where CMUXCLI names the app's routing type, not the CLI. The policy check moves to cmuxCLITests, which builds the CLI target. Refs #15488 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * test: cover vm poll interval boundaries * test: compile the vm ready poll policy into cmuxCLITests #16245 moved the vm poll-interval check into cmuxCLITests with `@testable import cmux_cli`, which cannot compile or link for the same reason as the hook store tests: cmux_cli is the CLI executable. The pure policy now lives in CLI/VMReadyPollInterval.swift, compiled into both the CLI and cmuxCLITests (the CMUXCLI+AutoNaming precedent), and CMUXCLI.vmReadyPollInterval delegates to it. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * test: drive hook state recovery through the bundled CLI #16196 added ClaudeHookSessionStoreRecoveryTests with `@testable import cmux_cli`. cmux_cli is the cmux-cli executable, which cmuxCLITests does not link and cannot host, so the target stopped compiling ("Unable to find module dependency: CmuxControlSocketAtomicsC / CmuxSimulatorSystem"), and adding those packages would only move the failure to link time. The two tests now seed the hook state file, run a real `cmux hooks claude session-start` against a mock socket, and read what the CLI left on disk, like the rest of cmuxCLITests: - a malformed sibling record no longer discards a valid session mapping, and a salvageable file is not quarantined; - each of two unreadable state files is moved to its own quarantine backup with its original bytes, and the store keeps working afterwards. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * Keep reconcile test within file budget * Give every app-host test process its own preferences domain App-host test processes all run the same cmux DEV bundle, so they shared the runner user's real com.cmuxterm.app.debug domain. CFFIXED_USER_HOME does not move it: cfprefsd resolves the path from the user account. What one process saved became the next process's starting state. The Dock tests (DockSocketLifecycleTests and others) save rightSidebar.mode=dock and fileExplorer.isVisible=true through FileExplorerState(), so a later process's createMainWindow() mounted the Dock while creating the window and testWorkspaceTerminalFontSizeShortcutSeedsDockCreatedAfterShortcut found a Dock before the shortcut. CmuxMain.main() now first calls TestProcessDefaults.installIfHostingTests(). In an XCTest host (CMUX_TEST_PROCESS, XCTestConfigurationFilePath or XCInjectBundleInto) it replaces +[NSUserDefaults standardUserDefaults] with a suite named <bundle id>.xctest.<pid>. A suite's search list has the argument, suite, global and registration domains but not the app's domain, so the process starts from registered defaults and keeps its writes. The suite is removed at exit; suites of crashed processes are removed by the next test process. @AppStorage, NSUserDefaultsController and package code all read UserDefaults.standard, so they follow. XCUITest target apps are not XCTest hosts and keep the real domain their tests seed. Code that names the app's domain explicitly (CloudTreeExpansionPreferences through Core Foundation, the scroll-bar preference and LanguageSettingsStore through persistentDomain(forName:)) now uses ProcessDefaultsDomain, so it sees the same domain as UserDefaults.standard. The window-frame reset from #15985 is removed: the process no longer sees an earlier process's frame. Its regression test now plants the frame in the shared domain the way an earlier process saved it. The Dock font-size test also sets the right sidebar hidden before it creates its window, because tests in the same process can still leave the Dock showing.

Summary
Some app-host unit tests only finish when a production timeout, drain bound, poll interval or retry delay runs out. This change applies the #15329 approach to them. Each timeout is now injectable, the production default does not change, and the tests pass a short value. No assertion changes.
Durations below come from the last main CI shard logs. "Expected" assumes the rest of each test takes the same time as before.

Why
drainMainQueuewas slow: a@MainActorSwift Testing body already runs inside a main-queue block, so the helper'sDispatchQueue.main.asynccannot run until the test returns. Every call therefore spun the run loop for its whole 1 s timeout. The helper now takes a timeout (default 1 s, so XCTest callers are unchanged), and these two Swift Testing suites spin for 0.1 s.Left alone on purpose, because the wait is the behavior under test:

Summary by cubic
App-host unit tests no longer wait out production timeouts — each timeout is now injectable with the same production default, tests pass a short value, and no assertions change. The suites save roughly 87 seconds of test time across the shards.
Refactors
drainMainQueuetakes a timeout;@MainActorSwift Testing bodies run inside a main queue block, so each call previously spun the run loop for a full second.CMUX_VM_WAIT_POLL_SECONDSandCMUX_VM_LAYOUT_OPEN_RETRY_DELAY_SECONDS; non-finite and oversized overrides fall back to production values (the wait poll capped at the remaining deadline), and new tests assert both fallbacks and the resulting poll count.TerminalCustomUploadRunnerdrain bounds,CloudTelemetryUploaderbatch delay, andAgentForkSupportprobe output timeout are injectable; the fork probe tests pass 2s instead of the 3s default.FileExplorerStatetakes an injectedUserDefaults, and sidebar mode availability now routes through it; the minimal-mode visibility test keeps the file explorer hidden so delayed workspace-root discovery cannot invalidate the chrome bodies.Written for commit d940a85. Summary will update on new commits.
