# Iron Legion Homelab Services Stack — Open Questions & Blockers

## Blocker Status
| # | Question | Impact | Default if Unresolved |
|---|----------|--------|----------------------|
| 1 | **Domain name** — Does Bobby own a domain (e.g., `bobbysh.me`) or do we use a fake TLD (`labs.internal`)? | **Critical** — TLS certs, Authelia, and DNS all depend on this. | Use `labs.internal` + self-signed CA |
| 2 | **Technitium upstream** — DoH, DoT, or plain UDP to upstream resolver (e.g., Cloudflare 1.1.1.1)? | Low — can default to DoH | DoH → `https://cloudflare-dns.com/dns-query` |
| 3 | **Pi-hole vs Technitium conflict** — Both run on MK7 port 53. Run Pi-hole on non-standard port with Technitium as conditional forwarder? Or separate nodes? | **Critical** — port 53 collision | Technitium on 53, Pi-hole on 5053, forward to Pi-hole from Technitium |
| 4 | **Jellyfin media storage** — External USB on MK7? SMB share? NVMe? | Medium | External USB mounted at `/media` on MK7 |
| 5 | **Backup target on MK7** — Capacity? Dedicated drive? Rsync target path? | Medium | `/backups/<service-name>/` on MK7 secondary storage |
| 6 | **Nextcloud database** — Use existing PostgreSQL on MK7, or deploy Nextcloud AIO (bundled)? | Medium — affects resource allocation on MK7 | Deploy standalone PostgreSQL container on MK7 for Nextcloud AIO is too heavy |
| 7 | **GPU on MK7** — NVIDIA driver runtime for Jellyfin transcode? | Low — falls back to CPU transcode | Use `jellyfin/jellyfin` with `NVIDIA_VISIBLE_DEVICES` env if available |
| 8 | **Notification routing** — Discord webhook? SMTP? File only? | Low — default file works | File notifications in `/opt/iron-legion/authelia/notifications/` |
| 9 | **Tailscale ACL policy** — Draft exists in Section 7. Bobby must review and apply in Tailscale admin console. | Low | Stay permissive until Bobby approves |
| 10 | **Beszel alert thresholds** — CPU %, memory %, disk % triggers not defined. | Low | Defaults in Beszel container |

## Outstanding Decisions Required
1. **Pi-hole inclusion** — Not in Bobby's original list. I added it as a DNS-layer complement to Technitium. **Remove if Bobby doesn't want it.**
2. **Authelia two-factor method** — TOTP via app (Google Authenticator) vs WebAuthn/FIDO2 keys?
3. **Home vs remote access** — If Bobby wants to share Jellyfin with friends/family outside Tailscale, public domain + Authelia guard is required.
