Trying to add an AHP host via SSH never completes.

github_app::remote_host::ssh::install エントリポイントから開始し、記録された ssh.exe コマンドと PowerShell 7 を使って Windows-to-Windows セットアップを再現します。標準入力経由で送信されたアーカイブが閉じられるかを追跡し、その後、ssh.exe プロセスが固まったりローディングスピナーが表示されたままになったりせずに AHP ホストの追加が完了することを確認します。

Trying to add an AHP host via SSH never completes. Windows on both client and server.

The last thing I see in the log is "github_app::remote_host::ssh::install: compatible copilotd not found; installing pinned version destination="meron-1" version="0.7.3"" and after that nothing happens. Some blank ssh.exe windows pop open and close over a few seconds until one finally stays open forever. Nothing else ever happens to complete adding the AHP host, it just keeps spinning the loading spinner and the ssh.exe window remains open.

Regular "ssh meron-1" works fine. Remote shell is powershell 7, in case it matters.

The ssh.exe that remains open seemingly forever has the following command line:

"C:\WINDOWS\System32\OpenSSH\ssh.exe" -o BatchMode=yes -o ConnectTimeout=10 -o ControlMaster=no -o ControlPath=none -- meron-1 "powershell -NoProfile -NonInteractive -EncodedCommand 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"

Decoded, that blob seems to be: $ErrorActionPreference='Stop'; $root=Join-Path $HOME '.copilotd\bin'; $zip=Join-Path $env:TEMP ('copilotd-'+[guid]::NewGuid()+'.zip'); $tmp=Join-Path $env:TEMP ('copilotd-'+[guid]::NewGuid()); try { $input=[Console]::OpenStandardInput(); $file=[IO.File]::Create($zip); $input.CopyTo($file); $file.Dispose(); New-Item -ItemType Directory -Force $tmp,$root | Out-Null; Expand-Archive -LiteralPath $zip -DestinationPath $tmp -Force; $exe=Get-ChildItem $tmp -Filter copilotd.exe -Recurse | Select-Object -First 1; if (-not $exe) { throw 'release archive did not contain copilotd.exe' }; $staged=Join-Path $root 'copilotd.exe.new'; Copy-Item $exe.FullName $staged -Force; Move-Item $staged (Join-Path $root 'copilotd.exe') -Force } finally { Remove-Item $zip,$tmp -Recurse -Force -ErrorAction SilentlyContinue }

So it reads the zip file from stdin. Presumably the failure for anything to happen is a side-effect of the stdin never closing. I wonder if this may be related to the SSH shell being PowerShell 7 instead of something more oldschool like cmd.exe? (Disproven)
