feat(desktop): add Windows support with an NSIS installer and release job - #81
Merged
Conversation
…askbar identity Windows has no signal delivery, so child.kill terminated only the Host PID and left node-pty shells and subagent hosts holding the loopback port. Kill the tree with taskkill /T /F in the child adapter, where every caller routes. Also: the packaged-runtime guard tested for a forward slash and so never fired on a Windows exec path; set the Application User Model ID so taskbar pinning survives an installer upgrade; and require the win32 node-pty prebuilds at pack time.
Replace the win "dir" target with a per-user NSIS installer that allows elevation and a selectable installation directory, so electron-updater has a latest.yml feed to read on Windows. Add dist:win, which refuses to run anywhere but a native Windows x64 host: the staged Host closure resolves platform-gated native packages at deploy time, so a macOS-staged tree cannot produce a working Windows build. A companion verifier sniffs the DOS and PE headers of both artifacts rather than trusting the file extension. Windows artifacts are unsigned until WIN_CSC_LINK and WIN_CSC_KEY_PASSWORD are configured; the workflow passes them through so signing needs no code change.
…dentials Node refuses to spawn a .cmd shim without a shell, so pnpm.cmd raised EINVAL and the Windows job never staged the Host closure. Spawn a bare pnpm through a shell on Windows and quote arguments cmd.exe would otherwise split. An unset GitHub secret interpolates to an empty string rather than to an absent variable, and electron-builder resolves an empty CSC_LINK as a certificate path -- path.resolve(appDir, '') is the app directory, so the mac job died on 'not a file'. Export only credentials that carry a value, and state the unsigned macOS path explicitly.
pnpm joins its workspace root with the deploy target instead of resolving it, so an absolute path on another volume became D:\repo\C:\Users\... and the Windows job failed with ERR_PNPM_ENOENT. A relative target is correct whether pnpm joins or resolves, and cannot cross a drive letter, so the staging directory moves onto the repository's own volume.
apps/desktop shipped 65 vitest cases and a typecheck script that no required check ran: the root vitest projects list stopped at apps/pythinker-code, and the typecheck job looped packages/* plus apps/pythinker-code only. A desktop regression merged green. Register the project and add a per-package typecheck step rather than extending the tsgo loop, which would cover the source tsconfig and silently skip tests/tsconfig.json.

oneClick and perMachine to enforce per-user installation: set allowElevation to

Included review availability: Your plan includes up to 3 reviews per rolling hour; 1 remains after this review.
spawnSync blocks the Electron main loop, so a stalled taskkill could freeze shutdown indefinitely. Cap it and let the existing fallback degrade to a single-process kill. The README claimed a per-user installer with no elevation required. With oneClick and perMachine both false, electron-builder shows an install-mode page, so per-user is the default rather than the contract. Describe the real behavior and pin it with a test.

Problem
apps/desktopshipped a macOS-only application.build.winused thedirtarget, which emits an unpacked directory and no installer, so Windows had
nothing to distribute and
electron-updaterhad nolatest.ymlfeed to read.Three Windows defects also lived in the shell itself, each dead or wrong code
rather than a missing feature:
host-supervisor.tsterminated the Host withchild.kill(). Windows has nosignal delivery, so that is
TerminateProcesson one PID and the Host's ownchildren — node-pty shells, subagent hosts — survived and kept holding the
loopback port.
nodeExecutable.includes('/'), which isnever true for
C:\...\Pythinker.exe. The check could not fire on Windows.app.setAppUserModelId, so taskbar pinning did not survive an installerupgrade and toasts were attributed to a generated identity.
Separately,
apps/desktop's 65 vitest cases and its typecheck script ran in norequired check, so a desktop regression merged green.
What changed
Windows packaging — per-user NSIS installer (
oneClick: false,perMachine: false, elevation allowed, installation directory selectable,desktop and Start Menu shortcuts),
dist:win, and awindows-latestreleasejob running in parallel with
mac.verify-win-installer.tssniffs the DOS andPE headers of both artifacts rather than trusting the file extension.
dist:winrefuses to run anywhere but native Windows x64. This is not caution:stage-runtime.tsrunspnpm deployon the build machine, and the closureresolves platform-gated natives — a macOS-staged tree carries
@opentui/core-darwin-arm64and cannot produce a working Windows build.Windows runtime — tree kill via
taskkill /T /F,isAbsolute()for theartifact guard,
setAppUserModelId, and anafterPackcheck for the win32node-ptyprebuilds.Release workflow — an unset GitHub secret interpolates to an empty string,
not to an absent variable, and electron-builder resolves an empty
CSC_LINKasa certificate path:
path.resolve(appDir, '')is the app directory, so themacOS job died on
not a file. Credentials are now exported only when theycarry a value, which also fixed the pre-existing macOS failure. Windows
artifacts are unsigned until
WIN_CSC_LINKandWIN_CSC_KEY_PASSWORDareconfigured; the job passes them through, so enabling signing needs no code
change.
Staging — Node refuses to spawn a
.cmdshim without a shell, sopnpm.cmdraised
EINVAL. And pnpm joins its workspace root with the deploy target ratherthan resolving it, so an absolute path on another volume became
D:\repo\C:\Users\.... The target is now workspace-relative, which is correctwhether pnpm joins or resolves, and the staging directory moved onto the
repository's own volume.
CI gates —
apps/desktopregistered in the root vitest projects, plus aper-package typecheck step. Deliberately not added to the
tsgoloop, whichcovers the source tsconfig and would silently skip
tests/tsconfig.json.Out of scope, and left alone: the reference implementation's Windows ACL runner
and pwsh sandbox trampoline (
packages/kaosandagent-corecarry their ownwin32 handling), Windows arm64, Linux packaging, and signing certificates.
apps/vscodehas the same CI-gate omission; that is pre-existing and belongs inits own change.
How this was verified
Windows packaging cannot be validated on a macOS workstation, so the proof is a
green CI run, not a local claim.

Locally, every added test was mutation-proved — the guard was reverted, the test
