wiki: seed all 4 ACG infrastructure system articles

gururmm-build (172.16.3.30), jupiter (172.16.3.20), pluto (172.16.3.36),
uranus (172.16.3.21) — verified IPs/hostnames against credentials.md,
pluto.md, and infra_office_network.md. wiki/index.md Systems table updated
to reflect seeded state; gururmm-build/jupiter/pluto/uranus removed from
compilation queue.

+# Uranus
+
+## Identity
+- **Hostname:** Uranus
+- **IP:** 172.16.3.21
+- **Role:** Secondary Unraid storage node — OwnCloud archive storage only
+- **Location:** ACG office
+- **OS:** Unraid 7.2.4 (kernel 6.12.54)
+- **History:** Formerly the 'Pavon' server at 172.16.1.33 (client-side hardware). Renamed and re-IP'd April 2026 when moved into ACG infrastructure. The IP 172.16.3.21 was previously Saturn's; Saturn was decommissioned April 2026 (Seafile migrated to Jupiter 2025-12-27) and this IP was reused.
+
+## Specs
+
+- **Hardware:** Dell PowerEdge R730xd
+- **CPU:** Intel Xeon E5-2630 v3 @ 2.40GHz, 32 threads
+- **RAM:** 7.7 GiB — **LOW; upgrade planned before any additional VM deployment**
+- **Array:** 6+ x 12 TB + 16 TB drives (~75 TB raw)
+
+## Services
+
+| Service | Notes |
+|---|---|
+| Unraid array | Primary role — bulk storage |
+| SMB share `Storage` | Pavon Archive; mounted as `/Archive` in OwnCloud for user `pavon` |
+
+**Uranus is storage only.** It is NOT a proxy, NOT a Docker host, NOT a VM host (RAM too low). NPM on Jupiter (.20) handles all reverse proxying — do not confuse Uranus with the proxy layer.
+
+## Access
+- **SSH:** root@172.16.3.21 port 22 — no key configured as of last documentation
+- **Password:** `bash D:/vault/scripts/vault.sh get-field infrastructure/uranus-unraid.sops.yaml credentials.password`
+- **Unraid Web UI:** http://172.16.3.21 (same password)
+- **Vault path:** `infrastructure/uranus-unraid.sops.yaml`
+
+## OwnCloud Integration
+
+SMB share `Storage` on Uranus is mounted as external storage in OwnCloud (cloud.acghosting.com / 172.16.3.22):
+- OwnCloud external storage mount ID: 6
+- Mount path in OwnCloud: `/Archive`
+- OwnCloud user: `pavon`
+
+## Known Issues & Quirks
+
+- **RAM is too low (7.7 GiB) for VM hosting** — future Windows build VM deployment (secondary Pluto) requires a RAM upgrade first.
+- **No SSH key configured** — password-only access as of last documentation. Add key before relying on it for automation.
+- **Saturn confusion** — any reference to "Saturn" in GuruRMM agent lists or logs that shows IP 172.16.3.21 is actually Uranus (IP was reused). Saturn is fully decommissioned.
+- **GuruRMM agent labeled "Saturn"** — one enrolled GuruRMM agent carries the "Saturn" label; its actual identity (stale entry vs. Uranus) is unverified.
