-### Phase 2: Reference
+### Phase 2: Reference (Complete)
 Information-oriented technical descriptions. Built first so other docs can link to reference material.

- [ ] Create `reference/` directory
- [ ] Service reference pages (migrate from zk cards)
- [ ] Infrastructure inventory
- [ ] Configuration reference
- [ ] API/CLI reference for mise tasks
+- [x] Create `reference/` directory with index
+- [x] Service reference pages (16 services: alloy, argocd, borgmatic, 1password, forgejo, grafana, jellyfin, kiwix, loki, miniflux, navidrome, postgresql, prometheus, teslamate, transmission, zot)
+- [x] Infrastructure inventory (hosts, tailscale, routing)
+- [x] Kubernetes reference (cluster, apps)
+- [x] Storage reference (sifaka, backups)

+
+Tailnet `tail8d86e.ts.net` provides secure networking for all BlumeOps infrastructure.
+
+## ACL Management
+
+ACLs managed via Pulumi in `pulumi/policy.hujson`.
+
+## Groups
+
+| Group | Members | Purpose |
+|-------|---------|---------|
+| `group:allisonflix` | admin, member | [[services/jellyfin|Jellyfin]] media access |
+
+## Device Tags
+
+| Tag | Devices | Purpose |
+|-----|---------|---------|
+| `tag:homelab` | indri | Server infrastructure |
+| `tag:nas` | sifaka | Network-attached storage |
+| `tag:blumeops` | indri, sifaka | Pulumi IaC managed resources |
+| `tag:registry` | indri | Container registry access |
+| `tag:k8s-api` | indri | Kubernetes API server access |
+
+**Important:** Don't tag user-owned devices (like gilbert). Tagging converts them to "tagged devices" which lose user identity and break user-based SSH rules.
+

+
+## Volume Mounting
+
+Pods mount NFS directly from [[storage/sifaka|Sifaka]]. Docker NATs outbound traffic through indri's LAN IP (192.168.1.50), allowing access to Sifaka's NFS exports.
+
+## Registry Mirror
+
+Containerd uses [[services/zot|Zot]] as a pull-through cache at `host.minikube.internal:5050`.

+# Grafana Alloy
+
+Unified observability collector for metrics and logs with two deployments:
+1. **Indri (host)** - System metrics and service logs from macOS host
+2. **Kubernetes (DaemonSet)** - Automatic pod log collection and service health probes
+
+## Quick Reference
+
+| Property | Value |
+|----------|-------|
+| **Indri Binary** | `~/.local/bin/alloy` |
+| **Indri Config** | `~/.config/grafana-alloy/config.alloy` |
+| **K8s Namespace** | `alloy` |
+| **K8s Image** | `grafana/alloy:v1.8.2` |
+| **ArgoCD App** | `alloy-k8s` |
+
+## Metrics Collected
+
+### From Indri
+- System metrics via `prometheus.exporter.unix`
+- Textfile collector: `minikube.prom`, `borgmatic.prom`, `zot.prom`, `jellyfin.prom`
+- Zot registry metrics from `http://localhost:5050/metrics`
+- Pushed to [[prometheus|Prometheus]] via remote_write
+
+### From Kubernetes
+- All pod logs via `loki.source.kubernetes`
+- Service health probes: miniflux, kiwix, transmission, devpi, argocd
+
+## Logs Collected
+
+**Brew services:** forgejo, tailscale
+
+**mcquack LaunchAgents:** alloy, borgmatic, zot, jellyfin
+
+Logs pushed to [[loki|Loki]] at `https://loki.tail8d86e.ts.net/loki/api/v1/push`.
+
+## Why Built from Source
+
+The Homebrew bottle uses `CGO_ENABLED=0`, which breaks Tailscale MagicDNS. Building with `CGO_ENABLED=1` uses the macOS native resolver.
+
+**Note:** This may no longer be needed now that services use `*.ops.eblu.me` URLs (routed via Caddy) instead of `*.tail8d86e.ts.net`. Should be tested in the future.

+|------|---------|
+| `/downloads/` | Active downloads and metadata |
+| `/downloads/complete/` | Completed downloads |

+| `/watch/` | Watch directory for .torrent files |
+
+[[kiwix|Kiwix]] reads from `/downloads/complete/` to serve ZIM archives.
+
+## Integration with Kiwix
+
+The Kiwix deployment includes a torrent-sync sidecar that:
+1. Reads ZIM torrent list from ConfigMap
+2. Adds missing torrents via RPC
+3. Runs on startup and every 30 minutes
+
+When downloads complete, the zim-watcher CronJob detects new ZIMs and restarts Kiwix.
+
+## Monitoring
+
+Basic uptime via blackbox probe in [[alloy|Alloy]] k8s (Services Health dashboard).
+
+Web UI shows: active/seeding/paused counts, speeds, disk usage.

+

+## Backup
+
+Sifaka is the **target** for [[operations/backup|backups]], not a backup source. [[services/borgmatic|Borgmatic]] sends backups TO sifaka, not OF sifaka.
+
+Data protection for sifaka itself currently relies on the Synology RAID 5 configuration, which provides single-disk fault tolerance. Future plans include offsite duplication for additional resiliency.
