 ## Current Architecture
 
 ### Storage Mounts
-- `/data/services` - NFS from `data-services.service.consul` (zippy primary, c1 standby)
-- `/data/media` - CIFS from fractal (existing, unchanged)
-- `/data/shared` - CIFS from fractal (existing, unchanged)

-### Hosts
-- **c1, c2, c3**: Cattle nodes, run most workloads, Nomad/Consul quorum members
-- **sparky**: Primary NFS server, runs workloads (affinity), NOT quorum, replicates to c1 every 5min
-- **chilly**: Home Assistant VM, cluster member (Consul agent + CLI tools), no workloads
-- **sparky**: Nomad worker
-- **beefy**: Desktop/laptop, cluster member (Consul agent + CLI tools), no workloads
-- **fractal**: Storage node (Proxmox/ZFS), will join quorum after GlusterFS removed
-- **sunny**: Standalone ethereum staking node (not in cluster)
+### Cluster Roles (check hosts/*/default.nix for each host's imports)
+- **Quorum**: hosts importing `nomad-server.nix` (3 expected for consensus)
+- **Workers**: hosts importing `nomad-worker.nix` (run Nomad jobs)
+- **NFS server**: host importing `nfs-services-server.nix` (affinity for direct disk access like DBs)
+- **Standby**: hosts importing `nfs-services-standby.nix` (receive replication)

 ## Key Patterns
 
 **NFS Server/Standby**:
-- Primary (zippy): imports `nfs-services-server.nix`, sets `standbys = ["c1"]`
-- Standby (c1): imports `nfs-services-standby.nix`, sets `replicationKeys = [...]`

+- Check host configs for current primary/standby assignments
