Two sweeps:
1. .30 is a PHYSICAL box (Lenovo ThinkCentre M83, Ubuntu 26.04), not a Jupiter
VM — the VM was decommissioned 2026-06-12. Fixed inventory tables and the
gururmm-build system page (overview, index, jupiter, gururmm-build,
POWER_FAILURE_RUNBOOK).
2. Windows build chain: Beast (GURU-BEAST-ROG, tailnet 100.101.122.4, i9-14900K)
is PRIMARY; Pluto (172.16.3.36) is FALLBACK. Verified against build-windows.sh
(`attempt_build beast || attempt_build pluto`). Fixed overview, index,
projects/gururmm (build-host table + flow + host detail), systems/pluto, and
the reference_pluto_build_server memory.
Submodule advanced: build-pipeline doc comments corrected to match.
