How to reach it

From	Do this
Terminal / iPhone (Termius)	`ssh minipc` then `brain` (attaches the Claude session) — or any admin command
Mac — full Claude UI	VSCode Remote-SSH into `minipc`, open `/home/justin/claude-workspace`, run the Claude Code extension on the host
Files (8TB)	Finder/Files → smb://100.72.42.97/8tb · user `justin` (same mini-PC password, in 1Password)
Web dashboards	HA `:8123` · Jellyfin `:8096` · Cockpit `:9090` (all over Tailscale)

Hardware & storage

Unified Claude brain — how it works

Two layers. (1) Shared knowledge — the workspace + .memory/ are kept identical on Mac, VPS and the box by Syncthing; continuity across sessions comes from .memory/ + /start-session / /end-session, not a live process. (2) Shared live session — Claude runs in the tmux brain session; attach from any device to pick up the same live context. The Mac can sleep; the brain stays on the box.

Component	Detail
Runtime	Node 24 (system) · `claude` 2.x global · tmux `brain` session (linger on = survives logout)
Attach	`ssh minipc` → `brain` → `claude`
MCP servers	`n8n-mcp` (HTTP) · `ghl-mcp` · `figma` · `canva` · (chrome-devtools omitted — no Chrome)
Secrets	`.env` mirrored from Mac (600). Hardening TODO: 1Password service-account token for dynamic pulls (`op` installed)
Billing	Interactive = subscription. Unattended/cron = API key (not subscription)
Future	When Mac mini M5 arrives, brain role migrates there; box reverts to HA + media + voice

What's left (needs you — can't be headless)

#	Action	Where
1	Log Claude in on the box	`ssh minipc` → `brain` → `claude` → `/login`
2	Connect smart-home devices (TP-Link Kasa first)	HA UI → Settings → Devices & Services
3	Jellyfin first-run (admin + add Movies/TV libraries)	http://100.72.42.97:8096
4	Pair Zigbee devices	HA → ZHA → Add device (physical pairing)
5	Tailscale: approve exit node + disable key expiry	login.tailscale.com/admin/machines
6	optional `gws auth login` (Google CLI) · 1P service-account token (secret hardening)	on the box
