Pluto (`PLUTO`, 172.16.3.36) is a Windows Server 2019 VM hosted on Jupiter (Unraid primary).

**Why:** It is the primary Windows build server for GuruRMM — builds all Windows agent variants (amd64, x86, legacy, debug), runs WiX 4 MSI builds, and signs binaries via Azure Trusted Signing.

**Credentials:** Administrator / `Paper123!@#` (set 2026-05-15). SSH key: `guru@gururmm-build` (ed25519, `Q+ivqd/...`) must be in `C:\ProgramData\ssh\administrators_authorized_keys` with icacls `/inheritance:r` and ASCII encoding (not UTF-16).

**How to apply:** When Pluto is unreachable or SSH auth fails, check Jupiter's VM console first (not physical machine). SSH key file must be ASCII-encoded — PowerShell `>` writes UTF-16 and breaks auth silently. Use `[System.IO.File]::WriteAllText(..., [System.Text.Encoding]::ASCII)` to write the key.

**GuruRMM agent:** Installed but historically runs old versions (was on 0.6.3 as of 2026-05-15). Update it after any Pluto maintenance.
