Cloud VMs: bake the TigerVNC desktop (dock, wallpaper, cua-driver, noVNC) into the devbox recipe and open it at the machine's private address - #11776
Merged
Conversation
Contract tests for the desktop layer every cmux Cloud machine must boot: TigerVNC on :1 with an openbox session, the tint2 dock, the CC0 wallpaper, TigerVNC's clipboard helper, the accessibility bus for computer-use, and noVNC on 6901, carried by the Dockerfile (started from cmux-devbox-boot when there is no systemd) and by the Freestyle bake (the cmux-desktop unit) from one install map and the Dockerfile's own package/Ghostty pins, with the session's DISPLAY and accessibility bus published to every shell family. Plus the Freestyle driver's openPort: the desktop and forwarded ports at the machine's private VPC address over the owner's tunnel, the desktop healed first, no public URL for a machine outside a private network. Red on purpose: the shared desktop contract module, the Dockerfile layer, the boot supervisor's desktop path and the driver's openPort land in the next commit (regression-test policy: the test commit fails, the fix commit passes).

…at the machine's private address The Freestyle bake already carried an openbox/TigerVNC desktop, but the Dockerfile (the reference recipe) had only a headless Xvfb, nothing pointed a shell or the cua computer-use driver at the screen, and no driver could open port 6901, so the Displays row failed on every Freestyle machine. Image (web/services/vms/images/devbox): the Dockerfile moves to ubuntu:24.04 (what freestyle/ubuntu runs) and bakes the same desktop layer the Freestyle bake installs: TigerVNC, openbox, the tint2 dock (Chrome, Files, Ghostty), Thunar, feh + the CC0 mountain-lake wallpaper, at-spi2-core, dbus, gdbus, TigerVNC's clipboard helper, noVNC + websockify. The desktop package list and the Ghostty .deb are Dockerfile ARGs that devbox-image-common.ts reads, and DEVBOX_DESKTOP_INSTALLS is the one file->path map the Dockerfile's COPYs, the Freestyle bake and the verifier are pinned to. cmux-devbox-boot runs cmux-desktop-boot as the uid-1000 user when there is no systemd (containers) and starts nothing under systemd, where the cmux-desktop unit owns it; the daemon loop is untouched. The Dockerfile self-checks the whole desktop at build time through the real supervisor and tears it down before the layer is committed. Session (desktop/start-vnc.sh): one D-Bus session bus reused across supervisor passes, at-spi-bus-launcher --launch-immediately, openbox, the wallpaper, tint2, vncconfig -nowin (copy/paste between the noVNC pane and X apps), the resize watcher, websockify. It publishes DISPLAY and the accessibility bus (AT_SPI_BUS_ADDRESS for AT-SPI clients, AT_SPI_BUS for cua-driver doctor) at /run/cmux-desktop/env (the unit's RuntimeDirectory); /etc/cmux/desktop-env.sh, sourced from profile.d and the bashrc chain, points any shell without a DISPLAY at the desktop while it is up, so agent-browser, xdotool and cua-driver mcp act on the screen a person can watch; the session's own user also inherits its D-Bus session bus, root does not. Driver (web/services/vms/drivers/freestyle.ts): openPort returns the machine's private VPC address (v4 first, the daemon route's reasoning), http://<addr>:6901/vnc.html?path=websockify for the desktop after a bounded guest heal that (re)starts cmux-desktop when noVNC is not listening, the bare origin for other ports, a ledger-only token, and never a public URL: noVNC has no auth of its own, so a machine outside a private network gets an error. web/services/vms/images/desktop.ts is the shared contract (ports, user, display, unit, runtime dir) the driver, bake, verifier and tests import. Bake/verify: the desktop-unit step and the verifier prove both ports (RFB loopback-only), the session processes, the wallpaper on the root window, exactly one desktop supervisor, DISPLAY in root's and ubuntu's login shells (buses only for ubuntu), root reaching the display, cua-driver doctor seeing the display and the accessibility bus, the registry answering, and every desktop file byte-identical. promote --pointer-slug none no longer passes the literal "none" to derive-devbox-sizes as a slug prefix. Trade-offs: the Dockerfile base moves from debian:bookworm-slim to ubuntu:24.04 so the reference recipe matches the only provider and the pinned Ghostty .deb installs; cmux sessions still run as root, so root shells get DISPLAY but not ubuntu's session bus.

…igest, review fixes Review feedback (CodeRabbit, the repo's no-hacky-sleeps rule): the desktop heal and the session start waited on elapsed time. Now every readiness signal comes from its owner: - cmux-desktop is Type=notify (NotifyAccess=all, TimeoutStartSec=120): start-vnc.sh sends READY once the display accepts connections, noVNC is bound and /run/cmux-desktop/env is published, so `systemctl start` (the driver's port-open heal, the bake's enable --now) returns exactly when the screen is usable. NOTIFY_SOCKET is stripped from everything the session spawns and handed only to that final notify: dbus-daemon is sd_notify-aware and reported READY for the whole unit the moment the session bus started (caught on a live machine). - Xvnc readiness is its own -displayfd (a FIFO opened read/write, read with a deadline); the accessibility bus is awaited by name (gdbus wait org.a11y.Bus); the resize watcher reacts to RandR events from xev instead of polling the geometry every 2 s. websockify has no readiness signal, so its 6901 bind is the one bounded connect wait (wait_listening). - The driver's heal is `[ -x start-vnc.sh ] || exit 3; systemctl start cmux-desktop || exit 1; ss :6901` (no loop); the bake's desktop-unit step drops its 90-iteration poll and pins Type=notify/NotifyAccess; the verifier pins them too. - The Ghostty .deb is verified against a checked-in SHA-256 (ARG CMUX_IMAGE_GHOSTTY_DEB_SHA256) before dpkg runs, in both recipes. - Docs: the cloud-vm skill says which machine kinds get a screen, the CLI contract escapes table pipes, promote documents the md slug exception; the TTL test uses a virtual clock; helper docstrings. Dry run on a live machine from the 11761a snapshot: restart returns in 0.9 s with noVNC bound, a stopped desktop heals in 0.6 s and returns only when up, a base image exits 3, the second pass reuses the session bus, a RandR resize re-fills the wallpaper through the event watcher, cua-driver doctor sees the display and the accessibility bus.

Let the guest exec exceed the systemd startup deadline.
The documented unit timeout is 120 seconds, but Line 1185 stops systemctl start after 90 seconds. A desktop that becomes ready between 90 and 120 seconds makes openPort fail even though systemd can still complete startup. Set this timeout above TimeoutStartSec with transport overhead.

Remove the socket polling loop from runtime startup.
wait_listening rescans the socket table after sleep 0.1 until a wall-clock deadline. This uses fixed-delay polling to synchronize websockify startup. Publish websockify readiness through an owner-controlled event or a tested cancellation-aware readiness abstraction instead.
As per coding guidelines, “Do not use fixed sleeps, delayed dispatch, timers, polling, or wall-clock waits to mask lifecycle, focus, rendering, socket, process, filesystem, network, teardown, startup, retry, or shared-state races.” As per path instructions, “flag fixed sleeps, timers, delayed dispatch, polling, or wall-clock waits used as synchronization.”

Require AT-SPI readiness before sending READY.
Line 209 ignores a failed gdbus wait. dbus-send can then produce an empty a11y_bus, but the script still publishes the environment and sets published=1. Lines 227-229 can therefore send READY=1, and openPort(6901) can expose the desktop while cua-driver has no accessibility bus. Require a successful name wait and a nonempty bus address before publication and readiness. Add a regression test for this failure path.

…s from newest main #11776 baked the TigerVNC desktop into the devbox image and #11756/#11776 gave the Freestyle driver its first openPort — the URL is the machine's private VPC address behind the WireGuard tunnel, never a public ingress. So --desktop no longer fails closed, vm desktop works on desktop-kind machines (private address on 6901, vpn required, base machines exit 1), and the port verbs are no longer dormant. The reference, SKILL.md, agent-workflows, and the bundled cloud-agent-skill now say so, and the in-flight notes shrink to what freestyle-vm-primitives still adds: the public TLS-edge previews on tokened subdomains and the vm-new desktop-by-default flip (vm base open has been desktop-default since #10948 — the CLI's two kind parsers differ today, which docs/cli-contract.md already papers over by describing the flipped default).

…, drift check, router prune fix (#10793) * worktree: drop stored defaults on identity lets so Xcode 26.6 builds main After #10781, worktreeDeviceID/worktreeFileID were both defaulted at the declaration and assigned in the explicit init, which the current toolchain rejects ("immutable value may only be initialized once"). The init's parameter defaults keep the same call-site contract. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * cli: cmux vm run/push/pull/wait and the cmux-cloud-vm agent skill vm run routes a command to a cloud machine without naming one: sticky per-directory binding, then an idle agent-pool machine, then a sleeper, then a freshly provisioned pool machine. push/pull move files over the exec channel (base64 chunks, SHA-256 verified, directories as tarballs); wait blocks until ready and optionally wakes the machine. The skill lets any coding agent drive machines from plain CLI. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * vm push: 64 KiB argv-bound chunks, no AppleDouble sidecars, line-safe progress Live dogfood on Blaxel: a 512 KiB chunk base64-encodes past Linux's 128 KiB per-argument limit ("argument list too long"), macOS tar shipped ._* files onto the machine, and chunk progress ran together when stderr was captured. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * vm run: pool membership is the persisted id list, not the display label; review fixes - The router now only drafts machines it provisioned itself (ids recorded in ~/.cmuxterm/vm-run-pool.json at create time, pruned when machines vanish); a user machine renamed agent-pool is never used. Test covers the impostor. - Staging tarball is removed if reading it throws before the defer is armed. - Push/pull chunk progress is localized (cli.vm.push.progress, cli.vm.pull.progress). - vm --help, the usage contract, and the contract doc list open/ports/tools/ handoff/promote-template, which the dispatcher already handled. - Sticky-binding fixture uses a fixed instant, not the host clock. - Skill recipes: --sync runs inside the synced dir (no remote $PWD), port readiness poll instead of sleep, eligibility filter instead of .vms[0], background test exit status captured to a status file. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * vm run: lock the pool store across processes; idempotent, run-scoped recipes - updateVMRunPool does the read-modify-write under flock on a sibling lock file, so two routers provisioning at once both land in the store; covered by a two-process test against two mock sockets. - Dev-server recipe reuses a live server or starts one with a workspace pidfile and log; test recipe uses per-run log/status paths written atomically. - Document that --sync is additive. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * vm run: pool-store failures propagate; recipes validate the dev server and use unique run ids - updateVMRunPool/saveVMRunPool throw on lock or write failure and createPoolVM reports the machine it provisioned but could not record, instead of a silent unlocked update. - The dev-server recipe reuses a server only when the recorded pid is alive and owns :3000 (netstat -p), refuses to start a second server on a port someone else owns, and clears stale metadata. - Test-run ids come from uuidgen, not the epoch second. - Skill docs: cmux vm shell is a cmux-tui session now that machines run the cmux-tui remote daemon; agents keep working through vm run/exec. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * vm run: regression test — pruning a stale pool id must keep an id recorded after the vm.list snapshot The mock socket records pool-2 while answering vm.list and returns a list that predates it; the store must end up {pool-1, pool-2} with gone-1 pruned. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01PEWn6ZZoGTAi67X3RSJ5aB * vm run: prune only ids the pre-list snapshot saw as gone; product-level pool-store error - Load the pool store before vm.list and subtract only the ids that snapshot lacks in the live list, instead of intersecting the locked set with a stale live snapshot, so a machine another vm run recorded meanwhile is never dropped from the pool. - The provisioned-but-unrecorded error no longer interpolates the raw pool-store error (lock path, OS text); it keeps the machine id and the recovery commands. - The unknown-size errors for vm run/route/agent list 24g, which parseCloudVMSize already accepts. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01PEWn6ZZoGTAi67X3RSJ5aB * cli: cmux vm <verb> --help prints the verb's own usage, offline --help/-h short-circuited to the cmux vm overview for every verb, so the option lists for run, route, agent, push, pull, wait, open, tree, workspace, terminal, tui, prompt, and base (--size, --timeout, placement flags, --json shapes) were unreachable without a running app and a usage error. A new CLI/CMUXCLI+VMHelp.swift maps those verbs to their usage strings; the prompt and base usages move out of the handler so they can be shared. Also: the overview lists workspace and terminal, points at per-verb help, no longer claims vm prompt --open accepts pi (the app supports claude|codex|opencode), and the shell/desktop lines read in order. docs/cli-contract.md: the vm/cloud usage probe now matches the binary (it lacked prompt, so the no-socket contract lane was red), plus one offline probe per routed verb and cmux surface --help. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01PEWn6ZZoGTAi67X3RSJ5aB * cmux-cloud-vm skill: the complete cmux Cloud CLI set, with a CI drift check references/commands.md is now the single reference for every cmux vm verb (and cmux cloud alias): usage, aliases, flags, --json shape, exit codes, the socket method it calls, and the sidebar action it mirrors, grouped machine / files / execution / routing / workspaces & terminals / surfaces & display / checkpoints & forks / networking & ports / account & plan, plus the app's vm.* socket table. Verbs that exist only in open PRs sit in one labeled "In flight" section (#11324 cmux fork, #11347), so the skill never names something an agent cannot run today; #11345 (vm terminal send|read|wait, the single sidebar Close Workspace…) merged during this work and is folded in. SKILL.md leads with vm run, then the glossary, cloud-vs-local, a need→verb table, headless terminal loops, agent policy, and troubleshooting. agent-workflows.md gains the headless-terminal recipe; openai.yaml describes the same scope for Codex; Resources/cloud-agent-skill.md (the copy vm prompt installs) no longer disagrees with the CLI (24g, vm base open, plain-terminal shell, ~30 s exec, vm wait/handoff/prompt/ssh-info/promote-template, fork/restore flags, per-verb --help). tests/test_cloud_vm_skill_coverage.py (workflow-guard-tests lane) parses the vm dispatcher, the workspace/terminal/surface sub-verbs, the usage line, the docs/cli-contract.md probe, and the advertised vm.* methods, and fails when the skill and the CLI disagree in either direction or when an in-flight verb has already shipped. Localization audit: CLI help/usage text follows the English-only CLI help convention; no Settings, menu, or web strings touched.

So the pool and binding stores, documented as HOME-relative, went to the real ~/.cmuxterm in every redirected run, and the router tests (main's own included) only passed under CI's app-host isolation, where the harness aligned CFFIXED_USER_HOME. Reproduced on a fleet Mac's GUI session (274 tests, 120 failures) with the same signature as the hosted lane. - CLI: vmRunStateHomeDirectory() prefers a non-empty $HOME, else NSHomeDirectory(); both store URLs use it. - cmuxTests: isolatedCLIChildEnvironment pins CFFIXED_USER_HOME to the supplied HOME unconditionally (XDG_CONFIG_HOME still only under the app-host isolation flag), so every spawned CLI agrees with the test.

The string constant becomes nonisolated; the default arguments become optional and resolve to .shared inside the main-actor bodies. Verified on a fleet builder: cmux-unit build-for-testing succeeds with zero warnings in these files. No behavior change; explicit-coordinator callers (tests) unchanged.

It now falls back to python3 plistlib when PlistBuddy is missing; the absolute path stays first so PATH can never shadow the reader in a release lane. - The fake archives in tests/test_ios_appstore_lane_identity.py never baked the production-origin keys a real Release build carries; both fixture writers now stamp CMUXAuthEnvironment/CMUXApiBaseURL/CMUXIrohBrokerBaseURL/ CMUXPresenceBaseURL. - The isolated-repo fixture copied upload-testflight.sh but not the new lib script it calls, so the auto-version lane failed on a missing file. tests/test_ios_appstore_lane_identity.py: 77/77 ok, exit 0 locally (macOS PlistBuddy path); the plistlib path verified standalone and by CI's Linux lane.

The formatters become Date.ISO8601FormatStyle constants (Sendable, same accepted formats) parsed via Date(_:strategy:), and the resolver — a pure function of its environment/defaults arguments over nonisolated PresenceSettings/AuthEnvironment statics — becomes nonisolated. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01PEWn6ZZoGTAi67X3RSJ5aB * skill: document cmux vpn hosts, extend the drift check to the vpn dispatcher, refresh the in-flight facts from freestyle-vm-primitives cmux vpn hosts landed with #11626 but the skill's vpn section stopped at revoke; the coverage check only parsed the vm dispatcher, so nothing caught it. The check now parses runVPNCommand the same way and fails on a vpn verb the reference misses or invents (it flagged the in-flight section's own wording during this change). The in-flight section also claimed a hosts verb family was arriving with the guest-CLI work — wrong on both ends: vpn hosts already ships here, and freestyle-vm-primitives has no vm hosts verb. Replaced with what that branch actually adds today: the guest cmux shim + in-VM notify bridge, vm help, the screen->display catalog kind rename, and the vm tree --refresh fleet re-read. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * skill: re-ground on the desktop image and live private-path port opens from newest main #11776 baked the TigerVNC desktop into the devbox image and #11756/#11776 gave the Freestyle driver its first openPort — the URL is the machine's private VPC address behind the WireGuard tunnel, never a public ingress. So --desktop no longer fails closed, vm desktop works on desktop-kind machines (private address on 6901, vpn required, base machines exit 1), and the port verbs are no longer dormant. The reference, SKILL.md, agent-workflows, and the bundled cloud-agent-skill now say so, and the in-flight notes shrink to what freestyle-vm-primitives still adds: the public TLS-edge previews on tokened subdomains and the vm-new desktop-by-default flip (vm base open has been desktop-default since #10948 — the CLI's two kind parsers differ today, which docs/cli-contract.md already papers over by describing the flipped default). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * skill: teach the delegation mission — persistence past the closed laptop, staged machine workspaces The point of the CLI is a local agent delegating work to the cloud, so the skill now says so up front (sessions live in the machine's daemon and survive the Mac disconnecting; reattach from any signed-in Mac) and gains the staged-workspace recipe: compose a named machine workspace's terminals headlessly with surface new-terminal --remote-workspace, verify with vm tree --json, and hand the user one click that opens the whole thing. Honest about today's two edges: vm workspace new always opens a local workspace as a side effect, and vm agent cannot target a workspace (use surface new-terminal with a login shell instead). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * cli+skill: the 20g plan machine is the only size preset — say so everywhere Main's plan-machine change (#11756/#11783) reduced cloudVMSizeAliases to 20g/20gb (or raw MB), but the error strings and usage lines still advertised the retired 2g-32g ladder — ours worse, still carrying the 24g we added when that preset existed. vm run/route/agent unknown-size errors, the vm new usage and unknown-flag text, docs/cli-contract.md's vm new row (matching the freestyle-vm-primitives wording to keep that merge clean), and every skill mention now name 20g (the 5 vCPU / 20 GB / 200 GB plan machine) or raw MB — matching parseCloudVMSize instead of misleading an agent into a rejected --size 8g. Also taken in this merge: main's #11754 landed the Linux iOS-guard fix this branch had been carrying, so those files resolve to main's (77/77 local pass). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * skill: note headless staging flags coming in freestyle-vm-primitives cmux176 implemented the two staging gaps flagged earlier — vm workspace new --no-open and vm agent --remote-workspace — so the in-flight section now names them and points §6b's workarounds at their replacement. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix: silence the guard-condition trailing-closure warning Xcode 26.3 added The critical-pressure teardown hardening (via main) left two compactMap trailing closures inside postAggregateMemoryPressureWarning's guard condition; Xcode 26.3's compiler warns 'trailing closure in this context is confusable with the body of the statement' on both (76:41, 77:41), which fails the warning-budget lane with actual=2 budget=0 — on main's own runs too (run 33716921978 shows the same +2). Parenthesized closure arguments are the fix the diagnostic prescribes; no behavior change. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix: adapt the Base create launch to the 3-argument coordinator Launch Two green PRs crossed on main: #10773 added a 2-argument MachineCreateCoordinator.start call in the Base sheet flow while #11773 changed Launch to (arguments, progress, completion) for the pending row's live output — main has not built the combination yet, and the first tree containing both fails with 'contextual closure type expects 3 arguments'. The Base flow now takes the progress handler and threads it through launchCloudVMBaseOpen into CloudVMActionLauncher's existing onOutput, so Base creates stream output to the pending row exactly like the New Machine sheet's flow in NewMachineSheetPresenter. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * test: make MachineCreateCoordinatorTests compile again after #11773 Two fixes for main's own test file (byte-identical there, so main's cmuxTests target does not compile either): #expect took the Bool? from optional-chained isSuperseded (== true resolves it), and the new MachinesPanelPendingCreateTests suite called Self.newMachineRequest for a helper that lives on MachineCreateCoordinatorTests — qualifying the type fixes the lookup and gives the trailing 'name: nil' its context.

None of those exist in the app: the PR landed only its test file. Since that merge (2026-09-06) every cmuxTests build on main fails, so no hosted unit test run can pass.

…, drift check, router prune fix (manaflow-ai#10793) * worktree: drop stored defaults on identity lets so Xcode 26.6 builds main After manaflow-ai#10781, worktreeDeviceID/worktreeFileID were both defaulted at the declaration and assigned in the explicit init, which the current toolchain rejects ("immutable value may only be initialized once"). The init's parameter defaults keep the same call-site contract. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * cli: cmux vm run/push/pull/wait and the cmux-cloud-vm agent skill vm run routes a command to a cloud machine without naming one: sticky per-directory binding, then an idle agent-pool machine, then a sleeper, then a freshly provisioned pool machine. push/pull move files over the exec channel (base64 chunks, SHA-256 verified, directories as tarballs); wait blocks until ready and optionally wakes the machine. The skill lets any coding agent drive machines from plain CLI. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * vm push: 64 KiB argv-bound chunks, no AppleDouble sidecars, line-safe progress Live dogfood on Blaxel: a 512 KiB chunk base64-encodes past Linux's 128 KiB per-argument limit ("argument list too long"), macOS tar shipped ._* files onto the machine, and chunk progress ran together when stderr was captured. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * vm run: pool membership is the persisted id list, not the display label; review fixes - The router now only drafts machines it provisioned itself (ids recorded in ~/.cmuxterm/vm-run-pool.json at create time, pruned when machines vanish); a user machine renamed agent-pool is never used. Test covers the impostor. - Staging tarball is removed if reading it throws before the defer is armed. - Push/pull chunk progress is localized (cli.vm.push.progress, cli.vm.pull.progress). - vm --help, the usage contract, and the contract doc list open/ports/tools/ handoff/promote-template, which the dispatcher already handled. - Sticky-binding fixture uses a fixed instant, not the host clock. - Skill recipes: --sync runs inside the synced dir (no remote $PWD), port readiness poll instead of sleep, eligibility filter instead of .vms[0], background test exit status captured to a status file. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * vm run: lock the pool store across processes; idempotent, run-scoped recipes - updateVMRunPool does the read-modify-write under flock on a sibling lock file, so two routers provisioning at once both land in the store; covered by a two-process test against two mock sockets. - Dev-server recipe reuses a live server or starts one with a workspace pidfile and log; test recipe uses per-run log/status paths written atomically. - Document that --sync is additive. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * vm run: pool-store failures propagate; recipes validate the dev server and use unique run ids - updateVMRunPool/saveVMRunPool throw on lock or write failure and createPoolVM reports the machine it provisioned but could not record, instead of a silent unlocked update. - The dev-server recipe reuses a server only when the recorded pid is alive and owns :3000 (netstat -p), refuses to start a second server on a port someone else owns, and clears stale metadata. - Test-run ids come from uuidgen, not the epoch second. - Skill docs: cmux vm shell is a cmux-tui session now that machines run the cmux-tui remote daemon; agents keep working through vm run/exec. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * vm run: regression test — pruning a stale pool id must keep an id recorded after the vm.list snapshot The mock socket records pool-2 while answering vm.list and returns a list that predates it; the store must end up {pool-1, pool-2} with gone-1 pruned. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01PEWn6ZZoGTAi67X3RSJ5aB * vm run: prune only ids the pre-list snapshot saw as gone; product-level pool-store error - Load the pool store before vm.list and subtract only the ids that snapshot lacks in the live list, instead of intersecting the locked set with a stale live snapshot, so a machine another vm run recorded meanwhile is never dropped from the pool. - The provisioned-but-unrecorded error no longer interpolates the raw pool-store error (lock path, OS text); it keeps the machine id and the recovery commands. - The unknown-size errors for vm run/route/agent list 24g, which parseCloudVMSize already accepts. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01PEWn6ZZoGTAi67X3RSJ5aB * cli: cmux vm <verb> --help prints the verb's own usage, offline --help/-h short-circuited to the cmux vm overview for every verb, so the option lists for run, route, agent, push, pull, wait, open, tree, workspace, terminal, tui, prompt, and base (--size, --timeout, placement flags, --json shapes) were unreachable without a running app and a usage error. A new CLI/CMUXCLI+VMHelp.swift maps those verbs to their usage strings; the prompt and base usages move out of the handler so they can be shared. Also: the overview lists workspace and terminal, points at per-verb help, no longer claims vm prompt --open accepts pi (the app supports claude|codex|opencode), and the shell/desktop lines read in order. docs/cli-contract.md: the vm/cloud usage probe now matches the binary (it lacked prompt, so the no-socket contract lane was red), plus one offline probe per routed verb and cmux surface --help. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01PEWn6ZZoGTAi67X3RSJ5aB * cmux-cloud-vm skill: the complete cmux Cloud CLI set, with a CI drift check references/commands.md is now the single reference for every cmux vm verb (and cmux cloud alias): usage, aliases, flags, --json shape, exit codes, the socket method it calls, and the sidebar action it mirrors, grouped machine / files / execution / routing / workspaces & terminals / surfaces & display / checkpoints & forks / networking & ports / account & plan, plus the app's vm.* socket table. Verbs that exist only in open PRs sit in one labeled "In flight" section (manaflow-ai#11324 cmux fork, manaflow-ai#11347), so the skill never names something an agent cannot run today; manaflow-ai#11345 (vm terminal send|read|wait, the single sidebar Close Workspace…) merged during this work and is folded in. SKILL.md leads with vm run, then the glossary, cloud-vs-local, a need→verb table, headless terminal loops, agent policy, and troubleshooting. agent-workflows.md gains the headless-terminal recipe; openai.yaml describes the same scope for Codex; Resources/cloud-agent-skill.md (the copy vm prompt installs) no longer disagrees with the CLI (24g, vm base open, plain-terminal shell, ~30 s exec, vm wait/handoff/prompt/ssh-info/promote-template, fork/restore flags, per-verb --help). tests/test_cloud_vm_skill_coverage.py (workflow-guard-tests lane) parses the vm dispatcher, the workspace/terminal/surface sub-verbs, the usage line, the docs/cli-contract.md probe, and the advertised vm.* methods, and fails when the skill and the CLI disagree in either direction or when an in-flight verb has already shipped. Localization audit: CLI help/usage text follows the English-only CLI help convention; no Settings, menu, or web strings touched. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01PEWn6ZZoGTAi67X3RSJ5aB * vm run: re-read the pool after pruning so a concurrently recorded machine is eligible; full -h probe needles A machine another vm run recorded between this run's pool load and vm.list (and that the list carries) was not in the pre-list snapshot, so it was ineligible for this run and could push it toward a needless provision or a false would_provision from vm route. The eligible set is now the post-prune store intersected with the live list. docs/cli-contract.md: the -h / cloud run / upload probes name the full usage line, same as their --help siblings.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01PEWn6ZZoGTAi67X3RSJ5aB * cmuxTests: align CFFIXED_USER_HOME with a test's HOME whenever the child inherits a CF home redirect On the hosted e2e lane the console session forwards CFFIXED_USER_HOME without CMUX_APP_HOST_ISOLATION_REQUIRED, so every CLI the process harness spawned resolved NSHomeDirectory() to the runner's home and ignored the test's HOME: the vm run pool/binding stores, SSH ~ expansion, and hook installs all landed outside the per-test home (126 failures across the class, including main's own testVMRunReusesIdlePoolMachine). The harness now aligns CFFIXED_USER_HOME with HOME when either the isolation flag is set or a CFFIXED_USER_HOME redirect is already present.

So the pool and binding stores, documented as HOME-relative, went to the real ~/.cmuxterm in every redirected run, and the router tests (main's own included) only passed under CI's app-host isolation, where the harness aligned CFFIXED_USER_HOME. Reproduced on a fleet Mac's GUI session (274 tests, 120 failures) with the same signature as the hosted lane. - CLI: vmRunStateHomeDirectory() prefers a non-empty $HOME, else NSHomeDirectory(); both store URLs use it. - cmuxTests: isolatedCLIChildEnvironment pins CFFIXED_USER_HOME to the supplied HOME unconditionally (XDG_CONFIG_HOME still only under the app-host isolation flag), so every spawned CLI agrees with the test.

The string constant becomes nonisolated; the default arguments become optional and resolve to .shared inside the main-actor bodies. Verified on a fleet builder: cmux-unit build-for-testing succeeds with zero warnings in these files. No behavior change; explicit-coordinator callers (tests) unchanged. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01PEWn6ZZoGTAi67X3RSJ5aB * skill: note manaflow-ai#11609's grow-only sizing under In flight * ci: make the manaflow-ai#11524 release-origins gate pass the Linux guard harness (fixes manaflow-ai#11757) Three gaps broke workflow-guard-tests on every merge ref since manaflow-ai#11524: - verify-ios-release-origins.sh read plists only via /usr/libexec/PlistBuddy, which does not exist on the Linux guard lane, so every key read <absent> and the gate failed closed. It now falls back to python3 plistlib when PlistBuddy is missing; the absolute path stays first so PATH can never shadow the reader in a release lane. - The fake archives in tests/test_ios_appstore_lane_identity.py never baked the production-origin keys a real Release build carries; both fixture writers now stamp CMUXAuthEnvironment/CMUXApiBaseURL/CMUXIrohBrokerBaseURL/ CMUXPresenceBaseURL. - The isolated-repo fixture copied upload-testflight.sh but not the new lib script it calls, so the auto-version lane failed on a missing file. tests/test_ios_appstore_lane_identity.py: 77/77 ok, exit 0 locally (macOS PlistBuddy path); the plistlib path verified standalone and by CI's Linux lane. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01PEWn6ZZoGTAi67X3RSJ5aB * cloud: Sendable ISO8601 parsing in VMClient; nonisolated presence URL resolver Newest main marked two ISO8601DateFormatter statics nonisolated (a warning: the type is not Sendable) and left PresenceHeartbeatClient.resolvedServiceURL main-actor-isolated while PresenceHeartbeatClientTests calls it from nonisolated Swift Testing contexts, which stops cmuxTests compiling on every app-host shard. The formatters become Date.ISO8601FormatStyle constants (Sendable, same accepted formats) parsed via Date(_:strategy:), and the resolver — a pure function of its environment/defaults arguments over nonisolated PresenceSettings/AuthEnvironment statics — becomes nonisolated. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01PEWn6ZZoGTAi67X3RSJ5aB * skill: document cmux vpn hosts, extend the drift check to the vpn dispatcher, refresh the in-flight facts from freestyle-vm-primitives cmux vpn hosts landed with manaflow-ai#11626 but the skill's vpn section stopped at revoke; the coverage check only parsed the vm dispatcher, so nothing caught it. The check now parses runVPNCommand the same way and fails on a vpn verb the reference misses or invents (it flagged the in-flight section's own wording during this change). The in-flight section also claimed a hosts verb family was arriving with the guest-CLI work — wrong on both ends: vpn hosts already ships here, and freestyle-vm-primitives has no vm hosts verb. Replaced with what that branch actually adds today: the guest cmux shim + in-VM notify bridge, vm help, the screen->display catalog kind rename, and the vm tree --refresh fleet re-read. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * skill: re-ground on the desktop image and live private-path port opens from newest main manaflow-ai#11776 baked the TigerVNC desktop into the devbox image and manaflow-ai#11756/manaflow-ai#11776 gave the Freestyle driver its first openPort — the URL is the machine's private VPC address behind the WireGuard tunnel, never a public ingress. So --desktop no longer fails closed, vm desktop works on desktop-kind machines (private address on 6901, vpn required, base machines exit 1), and the port verbs are no longer dormant. The reference, SKILL.md, agent-workflows, and the bundled cloud-agent-skill now say so, and the in-flight notes shrink to what freestyle-vm-primitives still adds: the public TLS-edge previews on tokened subdomains and the vm-new desktop-by-default flip (vm base open has been desktop-default since manaflow-ai#10948 — the CLI's two kind parsers differ today, which docs/cli-contract.md already papers over by describing the flipped default). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * skill: teach the delegation mission — persistence past the closed laptop, staged machine workspaces The point of the CLI is a local agent delegating work to the cloud, so the skill now says so up front (sessions live in the machine's daemon and survive the Mac disconnecting; reattach from any signed-in Mac) and gains the staged-workspace recipe: compose a named machine workspace's terminals headlessly with surface new-terminal --remote-workspace, verify with vm tree --json, and hand the user one click that opens the whole thing. Honest about today's two edges: vm workspace new always opens a local workspace as a side effect, and vm agent cannot target a workspace (use surface new-terminal with a login shell instead). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * cli+skill: the 20g plan machine is the only size preset — say so everywhere Main's plan-machine change (manaflow-ai#11756/manaflow-ai#11783) reduced cloudVMSizeAliases to 20g/20gb (or raw MB), but the error strings and usage lines still advertised the retired 2g-32g ladder — ours worse, still carrying the 24g we added when that preset existed. vm run/route/agent unknown-size errors, the vm new usage and unknown-flag text, docs/cli-contract.md's vm new row (matching the freestyle-vm-primitives wording to keep that merge clean), and every skill mention now name 20g (the 5 vCPU / 20 GB / 200 GB plan machine) or raw MB — matching parseCloudVMSize instead of misleading an agent into a rejected --size 8g. Also taken in this merge: main's manaflow-ai#11754 landed the Linux iOS-guard fix this branch had been carrying, so those files resolve to main's (77/77 local pass). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * skill: note headless staging flags coming in freestyle-vm-primitives cmux176 implemented the two staging gaps flagged earlier — vm workspace new --no-open and vm agent --remote-workspace — so the in-flight section now names them and points §6b's workarounds at their replacement. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix: silence the guard-condition trailing-closure warning Xcode 26.3 added The critical-pressure teardown hardening (via main) left two compactMap trailing closures inside postAggregateMemoryPressureWarning's guard condition; Xcode 26.3's compiler warns 'trailing closure in this context is confusable with the body of the statement' on both (76:41, 77:41), which fails the warning-budget lane with actual=2 budget=0 — on main's own runs too (run 33716921978 shows the same +2). Parenthesized closure arguments are the fix the diagnostic prescribes; no behavior change. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix: adapt the Base create launch to the 3-argument coordinator Launch Two green PRs crossed on main: manaflow-ai#10773 added a 2-argument MachineCreateCoordinator.start call in the Base sheet flow while manaflow-ai#11773 changed Launch to (arguments, progress, completion) for the pending row's live output — main has not built the combination yet, and the first tree containing both fails with 'contextual closure type expects 3 arguments'. The Base flow now takes the progress handler and threads it through launchCloudVMBaseOpen into CloudVMActionLauncher's existing onOutput, so Base creates stream output to the pending row exactly like the New Machine sheet's flow in NewMachineSheetPresenter. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * test: make MachineCreateCoordinatorTests compile again after manaflow-ai#11773 Two fixes for main's own test file (byte-identical there, so main's cmuxTests target does not compile either): #expect took the Bool? from optional-chained isSuperseded (== true resolves it), and the new MachinesPanelPendingCreateTests suite called Self.newMachineRequest for a helper that lives on MachineCreateCoordinatorTests — qualifying the type fixes the lookup and gives the trailing 'name: nil' its context.

None of those exist in the app: the PR landed only its test file. Since that merge (2026-09-06) every cmuxTests build on main fails, so no hosted unit test run can pass.

What the Freestyle base snapshot now bakes
The desktop layer under
web/services/vms/images/devbox/desktop/, the same stack the retired Blaxelcmux-devboximage had, now in both recipes:Xvnc :1, RFB 5901 loopback-only, no VNC-level auth) serving an openbox sessioncmux vm open <m>:desktopopenat-spi2-core,at-spi-bus-launcher --launch-immediately) andgdbus, so the pinned cua-driver (0.23.2, already installed) can read window trees; TigerVNC's clipboard helper (vncconfig -nowin) so copy/paste works between the noVNC pane and X appsDISPLAYand the accessibility bus (AT_SPI_BUS_ADDRESSfor AT-SPI clients,AT_SPI_BUSforcua-driver doctor) at/run/cmux-desktop/env;/etc/cmux/desktop-env.sh(profile.d + the bashrc chain, so every cmux-tui pane) points any shell without aDISPLAYat the desktop while it is up, soagent-browser,xdotoolandcua-driver mcpact on the screen a person can watchThe Dockerfile is the reference recipe again: it moves to
ubuntu:24.04(whatfreestyle/ubunturuns), bakes the desktop layer, and self-checks it at build time through the real boot supervisor. The desktop package list and the Ghostty.debare DockerfileARGs thatdevbox-image-common.tsreads, andDEVBOX_DESKTOP_INSTALLSis the single file → path map the Dockerfile'sCOPYs, the Freestyle bake, and the verifier are all pinned to, so the two recipes cannot drift.web/services/vms/images/desktop.tsis the shared contract (ports, user, display, unit, runtime dir) the driver, bake, verifier, and tests import.Boot / supervision
cmux-desktopunit runscmux-desktop-bootas the work userubuntu(RuntimeDirectory=cmux-desktopfor the published env) and re-runs the idempotentstart-vnc.shevery 30 s; every component is guarded by a liveness probe, one D-Bus session bus is reused across passes.Type=notifyandstart-vnc.shsends READY once the display accepts connections, noVNC is bound and the env is published, sosystemctl start cmux-desktopreturns exactly when the screen is usable (that is what the driver's heal and the bake block on;NOTIFY_SOCKETis stripped from everything else the session spawns because dbus-daemon would otherwise report READY for the whole unit). Xvnc readiness is its own-displayfd, the accessibility bus is awaited by name (gdbus wait org.a11y.Bus), the resize watcher reacts to RandR events fromxev. websockify has no readiness signal, so its 6901 bind is the one bounded connect wait.cmux-devbox-bootruns the samecmux-desktop-bootas the uid-1000 account and restarts it if it exits. Under systemd it starts nothing; the bake and the verifier count exactly one desktop supervisor.cmux-devbox-bootis byte-identical to the drivers' command (test-pinned); the desktop is a sibling process, never a child of the daemon.Opening it (web driver, no Swift changes)
FreestyleProvider.openPort(thePOST /api/vm/[id]/open-portpath the Displays row already calls) returns the machine's private VPC address over the owner's WireGuard tunnel, the same path the daemon route takes:http://<private v4>:6901/vnc.html?path=websockifyfor the desktop (after one blockingsystemctl start cmux-desktop, a no-op on a healthy machine), the bare origin for other ports, a ledger-only token. The Ghostty.debis now verified against a checked-in SHA-256 in both recipes. noVNC has no auth of its own, so a machine outside a private network gets an error, never a public URL. The sidebar rework in #11762 can keep using this endpoint or read the address directly; nothing inSources/changes here.Verification
