+name: Obsidian vault folder structure
+description: Homelab-2026 is the active docs folder; Homelab-New is archived
+type: reference
+---
+
+The Obsidian vault at `/Users/csader/Documents/Sader/` has the homelab docs at:
+
+- `4 - Areas/Home/Homelab-2026/` — ACTIVE, canonical documentation
+- `4 - Areas/Home/Homelab-New/` — STALE, mostly empty (only `Infrastructure/Docker-Swarm-Cluster/`)
+- `4 - Areas/Home/Homelab/` — STALE, old archived content
+
+**Why:** A second vault reorganization moved active docs from Homelab-New into Homelab-2026. Homelab-New and Homelab are kept for archive purposes.
+
+**How to apply:** Always read from and write to `Homelab-2026`. Key files:
+- `Homelab-2026/Infrastructure Overview.md` — Service inventory
+- `Homelab-2026/Home Assistant Automations.md` — HA automation reference
+- `Homelab-2026/Known Issues.md` — Active issues tracker
+- `Homelab-2026/Hosts/` — Per-host documentation
+- `Homelab-2026/Network/Topology.md` — Network topology
+- `Homelab-2026/Archived Docs/` — Old Homelab and Homelab-New archives
