Summary

The desktop app (app/electron) now builds for Windows x64, and the server serves the herdr-core runtime on Windows.

herdr-core 0.1.17 ships herdr-core-windows-x86_64.zip (herdr-core.exe plus the ConPTY it runs terminals on, conpty\), and listens on a named pipe. The server already talks to hc through hc connect over stdin/stdout, so the only missing piece was the adapter the server's herdr client connects to (HERDR_SOCKET), which listened on a unix socket file.

Server

• server/herdr-core/pipe.ts (new): the adapter's address. Outside Windows it stays herdr-core.sock in the state folder. On Windows it is \\.\pipe\ovis-herdr-core-<sha256 of the lowercased, resolved state folder>, so two servers on one state folder still meet on one pipe and the second one is refused, as with the socket file.
• server/herdr-core/runtime.ts: herdr-core is served on Windows too. The owner-uid and mode checks (chmod 0700/0600) run only outside Windows. herdr/client.ts already leaves a \\.\pipe\ address as it is.
• On Windows the pipe is named after the state folder's real path (realpathSync.native), so a junction or a short 8.3 spelling of the same folder names the same pipe.
• server/completion.ts: the completion tracker's herdr identity does not stat a named pipe (a stat opens a connection to the adapter). pipeIdentity (the pipe's name plus a per-process nonce) stands instead, as below.
• server/herdr-core/discovery.ts: a stat of hc's own Windows pipe answers EBUSY while each of its instances is taken. That now counts as a running core (it read as not running in the VM with the core up).
• server/herdr-core/adapter.ts: on Windows server.agent_manifests offers no kinds. hc's shell there is PowerShell or cmd, which the typed agent start does not quote for, and agent.start already refuses it (agent_pane_unsupported). Starting an agent from a pane stays a follow-up.
• server/agents-routes.ts: /api/agents adds Oh My Pi and Claude Code itself only on herdr (whose built-ins they are). On herdr-core the adapter's manifests already name every kind its panes can start, so Windows offers none it cannot start (the omo review reproduced Claude Code being offered and then failing with agent_pane_unsupported). The new test fails without the change.
• server/finishes.ts: on Windows finishHerdrIdentity reads HERDR_SOCKET as herdr's pid:start marker file. With the adapter's pipe there, that readFileSync would connect to the adapter and wait for an answer that never comes, blocking the server. pipeIdentity stands instead: the pipe's name plus a nonce made once per server process. So like the socket file recreated on every start on Linux and macOS, it changes with each server and stays the same while one runs.
• The Settings runtime switch and the automatic choice stay herdr-only on Windows (runtime-choice.ts unchanged): only an explicit OVIS_RUNTIME=herdr-core, which the desktop app sets, serves herdr-core there.

Desktop app

• scripts/runtimes.ts: a win32-x64 target, with pinned hc (windows-x86_64.zip, SHA-256 from releases.herdr.dev's 0.1.17 manifest) and Bun (bun-windows-x64.zip, from Bun 1.4.2's SHASUMS256.txt).
• scripts/build.ts: unpacks with Windows' own tar.exe (Git Bash's GNU tar cannot open zips), stages herdr-core.exe, conpty\ and bun.exe, keeps hc's THIRD-PARTY-NOTICES\ folder (ConPTY's license and notice), and runs electron-builder --win.
• electron-builder.yml: an NSIS target, one-click and per user (no administrator prompt), Ovis-win-x64.exe (versionless, like the Linux and macOS names on main). It installs to %LOCALAPPDATA%\Programs\ovis-desktop (from package.json's name), so it does not overwrite the Windows shell's %LOCALAPPDATA%\Programs\Ovis. Both add a Start Menu entry named Ovis. Unsigned: no signing settings or secrets were added.
• scripts/build.ts writes the Windows .ico (PNG entries, 16 to 256 px, through Bun.Image). electron-builder's own PNG conversion spun for over 10 minutes on the 1024 px icon under Bun's node in the VM.
• src/children.ts:
  • The .exe names.
  • The first copy of the core into user data takes conpty\ along, before the exe. hc update --from already brings the bundled one's ConPTY.
  • No /bin/bash wrapper on Windows.
  • windowsHide on every child.
  • Without ps, a leftover server's command line and start time come from CIM (Get-CimInstance Win32_Process). Windows' quoted program path is accepted.

Release (workflow change: needs the owner's OK)

• .github/workflows/desktop.yml:
  • Adds a win32-x64 build on windows-2025. Its steps run in bash, as on the other runners, with Git Bash on Windows.
  • Its Ovis-win-x64.exe, .blockmap and latest.yml go into the release files.
  • latest.yml, Ovis-win-x64.exe and its blockmap join the names the gather step requires before anything is attached.
  • A Windows signing hook mirrors the Mac one: off until the repository variable DESKTOP_WIN_SIGN is true, then electron-builder signs with WIN_CSC_LINK (base64 .pfx) and WIN_CSC_KEY_PASSWORD, and the build fails if either is missing. Unsigned until then.
• .github/workflows/release.yml passes those two secrets to the desktop call (empty when unset).
• windows-app.yml (Ovis.exe, Ovis.msix of the Windows setup app) is unchanged.
• app/electron/src/children.test.ts: the tests built on POSIX shell stand-ins (startServer, endLeftover, the hc swap and rollback) are skipped on Windows, so the Windows job's bun test runs the rest: 39 pass, 10 skip, 0 fail in the Windows VM.
• docs/development.md lists the Windows installer and its feed.

Validation

• After merging origin/main (ci(desktop): attach the desktop app and its update feed to releases (needs owner OK) #2793's mac signing/deb kept; the Windows build takes its versionless name): Windows VM on 8f223a5f passed build (Ovis-win-x64.exe), silent install, launch, /api/health runtime: herdr-core with herdr_core.running: true, an hc terminal in /api/session, and uninstall. bun run check fast green on 94ea82fe (11345 pass). The agents fix is server-only and covered by server/agents-routes.test.ts; the VM run was not repeated for it.

• Linux: bun run check fast (result below); bun test server/herdr-core/pipe.test.ts server/herdr-core/runtime.test.ts server/herdr-core/runtime-choice.test.ts server/finishes.test.ts; in app/electron, bun test (33 pass) and bun run typecheck.

• Windows 11 VM (desktop session, fresh %TEMP% clone of this branch, deleted afterwards; isolated HC_SESSION and --user-data-dir):

  • Probe: Bun 1.4.2 Bun.listen/Bun.connect on \\.\pipe\… work; a second listener gets EADDRINUSE; a closed pipe answers ENOENT (so the adapter's existing "another Ovis still listens" check holds); hc server start and hc connect answer hello.
  • bun test of the four server files above: the new Windows test passes (the adapter listens on the pipe, HERDR_SOCKET points at it, a second server on the same state folder is refused, and a restart takes the pipe again). See the note below on the one other failure.
  • E2E on this branch (bun run dist, silent install, launch with an isolated --user-data-dir and HC_SESSION, then uninstall):
    • The build makes Ovis-win-x64.exe (221.6 MB), whose resources\ovis\bin holds herdr-core.exe, bun.exe and conpty\conpty.dll/conpty\x64\OpenConsole.exe.
    • /S installs to %LOCALAPPDATA%\Programs\ovis-desktop\Ovis.exe with a Start Menu Ovis.lnk.
    • The app starts the core and the server (Ovis listening on http://127.0.0.1:60163), and /api/health answers "runtime":"herdr-core", "herdr_runtime":{"serving":"herdr-core","source":"env"}.
    • The adapter listens on \\.\pipe\ovis-herdr-core-0d6e9e8573bf0849ab16ad1ce5f232a6.
    • A terminal started with hc run --bg cmd.exe … in the app's core session shows up in the server's /api/session as pane t1 ("Other terminals").
    • The uninstaller (/currentuser /S) removes the folder, the shortcut and the uninstall key.

Skipped: the Native Windows install CI set is unchanged by this PR and runs in CI.

Note: server/herdr-core/runtime-choice.test.ts "keeps herdr wherever herdr's TUI left a trace" fails when run on Windows, through a path this PR does not touch: it simulates platform: "linux" and expects Bun.which to find an extensionless custom-herdr on Windows. That file is not in the Windows CI set.

Summary

Summary by CodeRabbit

• New Features
  • Added support for the Windows x64 desktop app, including a per-user installer and Windows-specific server startup.
  • Added Windows named-pipe connections between the desktop app and its core service.
• Bug Fixes
  • Improved detection of existing Windows service processes and connections.
• Documentation
  • Added Windows build, installation, and usage instructions.
• Limitations
  • Agent manifests and shell-started agents are unavailable on Windows.

This change adds Windows x64 support for the desktop app and herdr-core. It introduces named-pipe communication, Windows-specific process handling, runtime assets, and a per-user NSIS installer. The adapter does not offer typed agent starts on Windows.

Changes: Windows Support

Layer / File(s)	Summary
Named-pipe runtime and discovery server/herdr-core/pipe.ts, server/herdr-core/runtime.ts, server/herdr-core/discovery.ts, server/herdr-core/pipe.test.ts, server/herdr-core/runtime.test.ts	herdr-core derives a Windows named-pipe address from the resolved state directory. Runtime startup accepts Windows and skips Unix ownership and permission checks there. Discovery treats EBUSY as evidence that a path exists. Tests cover address normalization, duplicate startup, and cleanup.
Named-pipe consumers and Windows adapter behavior server/completion.ts, server/finishes.ts, server/herdr-core/adapter.ts, server/herdr-core/adapter.test.ts	Completion and finish identity checks use pipe identities for named pipes. On Windows, the adapter returns an empty agent manifest list; tests check the unsupported typed-start response and that no input is typed.
Electron runtime and child-process handling app/electron/scripts/runtimes.ts, app/electron/scripts/runtimes.test.ts, app/electron/src/children.ts, app/electron/src/children.test.ts	Runtime pins add Windows x64 Bun and herdr-core archives. Child-process handling uses .exe paths, installs bundled ConPTY files, launches programs directly on Windows, and uses PowerShell/CIM for process inspection. Tests cover these Windows paths.
Windows installer and usage documentation app/electron/scripts/build.ts, app/electron/electron-builder.yml, app/electron/README.md, changelog.d/desktop-app-windows.md	The build stages Windows runtime assets, generates an ICO, and selects the NSIS target. Installer configuration enables one-click per-user installation. Documentation describes Windows paths, process behavior, and a PowerShell launch example.

Explanation

The title names the main change: a Windows build of the desktop app, with herdr-core served over a named pipe. The changeset covers both parts (NSIS installer, ConPTY/Bun staging, and the pipe adapter). The '(needs owner OK)' suffix is process noise, but the title still describes the primary change. The title is 100 characters, which is long but within a reasonable single-line range.

Full details: Description check

Explanation

The description clearly explains the Windows x64 build, named-pipe runtime support, desktop packaging, known limitations, validation results, and skipped checks. It includes a detailed Validation section. It uses ## Summary instead of the template’s ## Change heading and does not link a maintainer-approved issue for the feature, but the required information is otherwise mostly complete.

Review notes for this PR (omo review CLEAR at 8cbf94fc, after one fix round; Codex Terra xhigh adversarial review run on the branch before that round).

Fixed in this PR:

• MEDIUM (reproduced by the omo review at ff99eccb): the adapter offered agent kinds on Windows, but the typed agent.start only takes a POSIX shell, and hc's Windows shell is PowerShell or cmd. Windows now offers no kinds (server.agent_manifests), with a test.
• MEDIUM (Codex): the completion tracker stated HERDR_SOCKET, which on Windows is now the adapter's pipe. It now uses pipeIdentity, as finishes.ts does.
• MEDIUM (Codex): a junction or a short 8.3 spelling of the state folder named a different pipe, so two servers could share one state folder. The pipe is now named after realpathSync.native of the folder, with a Windows test through a junction.
• MEDIUM (omo, unreproduced): the Windows identity never changed. It is now the pipe's name plus a nonce made once per server process, as the socket file recreated on every start is on Linux and macOS.
• Found in the VM: a stat of hc's Windows pipe answers EBUSY while its instances are taken, so Settings' herdr-core facts said running: false with the core up. EBUSY now counts as running.
• LOW: README install path (%LOCALAPPDATA%\Programs\ovis-desktop) and the undefined $d in its PowerShell snippet; the new ConPTY test waits for its log to close.

Left as they are (LOW, none reproduced as a user-facing problem):

• pipeIdentity is per server process, not per hc core: restarting Ovis while the core keeps running reads as a new herdr. Linux and macOS behave the same today (the adapter's socket file is recreated on every start).
• The pipe name is predictable and has libuv's default access rules: another local user could create it first and keep Ovis from starting (EADDRINUSE / "Another Ovis owns this state directory"), not read or answer for it. herdr's own Windows pipe has the same exposure.
• server/bridge.ts bridgeIdentity still stats the socket path. That matters only for a Windows herdr-core server added as another PC's bridge, which the desktop app is not.
• processStartSync starts PowerShell on Windows (CIM) and blocks Electron's main process while it answers, usually 1 to 3 s, each time the server starts.
• app/electron's startServer/endLeftover/installCore swap tests use POSIX shell stand-ins and do not run on Windows; desktop CI runs on Linux and macOS. The Windows-relevant ones were run in the VM.
• server/herdr-core/runtime-choice.test.ts "keeps herdr wherever herdr's TUI left a trace" fails when run on Windows, through a path this PR does not touch (a simulated platform: "linux" expecting Bun.which to find an extensionless file); it is not in the Windows CI set.

Windows VM check on the final head 8cbf94fc (fresh %TEMP% clone, isolated HC_SESSION and --user-data-dir, all removed afterwards):

• bun run dist builds Ovis-Setup-0.4.22-x64.exe.
• /S installs it to %LOCALAPPDATA%\Programs\ovis-desktop.
• The app starts the core and the server. /api/health answers runtime: herdr-core and herdr_core.running: true, and the adapter listens on \\.\pipe\ovis-herdr-core-<hash>.
• A terminal hc run --bg started shows up in /api/session as pane t1.
• The uninstaller removes the app.

The failed Integration tests run on this head passed all of its tests (1039 pass, 0 fail); it was invalidated by check: source changed during the check on the runner, and is being re-run.

Minor · Performance & Scalability · Poor tradeoff

Move the Windows start-time lookup off the Electron main thread.

On Windows, each server start runs processStartSync through execFileSync, which blocks the main process for up to 15 seconds. The call sits in the startServer onSpawn callback in main.ts. While it runs, the app cannot handle window, tray, or quit events. Resolve the start time asynchronously and keep the pid record written before startup. A record without a start time is never cleaned up, so check crash recovery with the change.

server/herdr-core/runtime.test.ts: 1

164-165: Trivial · Maintainability & Code Quality · Quick win

Send an RPC through the pipe in the Windows transport test.

The test name says the herdr client reaches the named pipe. Its only client-side check, socketAddress(adapter.socketPath), returns the pipe path unchanged and never opens a connection. A broken Windows client connection would still pass this test. The Native Windows install job also does not run this file.

Send one request through the pipe and assert that the adapter replies:

Suggested test change

-import { socketAddress } from "../herdr/client.ts";
+import { herdrRpc, socketAddress } from "../herdr/client.ts";

   expect(socketAddress(adapter.socketPath)).toBe(adapter.socketPath);
+  // the client sends a request through the pipe and gets the adapter's reply
+  const snapshot = await herdrRpc("session.snapshot", {}, adapter.socketPath);
+  expect(snapshot).toBeDefined();

Run the test on the Windows CI job. Use a name filter, because the file also holds Unix-only tests:

Suggested CI change

       - run: bun test ./scripts/windows-plugin.test.ts ./scripts/plugin-runtime.test.ts ./scripts/phone-setup.test.ts ./server/windows-native.test.ts ./server/omp-images.test.ts ./server/claude-command-history.test.ts

91-92: Minor · Potential issue · Heavy lift

Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.

Windows upgrades rely entirely on hc update --from to transfer the bundled ConPTY directory; installCore itself copies that directory only on first installation. The updater may replace the executable without completing this new companion-file contract.

The upgraded core may fail to create terminals because its installed ConPTY files are missing or incompatible.

This can occur when: An existing Windows installation upgrades to a bundled core requiring different ConPTY files.

Review notes at a48108ef (omo review CLEAR; Codex Terra xhigh ran inside it):

• MEDIUM, unreproduced: the installer's Start menu shortcut is Ovis.lnk, the same name the Windows setup app (app/windows) writes, so on a PC with both each install takes the other's shortcut. Not renamed here: the follow-up on top of this PR (branch feat/desktop-windows-replace-shell) makes the desktop installer replace the setup app: it removes the setup app's sign-in start, copy, windows and shortcuts, and never runs its Remove, which would take the Ovis server off the PC. It is being checked in the Windows VM with the setup app installed first.
• LOW: a Windows app on the beta channel reads the desktop-beta feed, which beta.yml does not build for Windows yet (as for darwin-x64 today). Follow-up: a win32-x64 entry in beta.yml.
• Notes: pipeIdentity is per server process, as the socket file's identity is on Linux and macOS; the adapter's "another Ovis owns this state directory" check reads existsSync, which the Windows VM test showed answers true for the adapter's own pipe.

Earlier on this PR: the reproduced MEDIUM (/api/agents offering Claude Code and Oh My Pi on Windows herdr-core, which cannot start them) is fixed in 15f231ca with a test that fails without it.
