+## What This Repo Is
+
+Sovran_SystemsOS is defined entirely as a **Nix flake** (`flake.nix`) and built from source. There is no pre-built binary — the System Installer is produced from this tree. Everything the system does is declared here.
+
+The control center is the **Hub** — a built-in panel that lets the operator launch, monitor, and toggle services without touching a terminal. Under the hood, the Hub writes to `custom.nix`, which feeds back into the flake.
+
+## Architecture

+
+- **`flake.nix`** declares two NixOS configurations:
+  - `nixosConfigurations.nixos` — the running system.
+  - `nixosConfigurations.sovran_systemsos-iso` — the System Installer.
+- **`configuration.nix`** owns host concerns (boot, filesystems, users, desktop, locale, Nix settings, firewall, audio, backups).
+- **`modules/modules.nix`** is the service router. Every other module is opt-in via flags read from `role-state.nix` and `custom.nix`.
+
+## Module Catalog
+
+Defaults follow the import order in `modules/modules.nix`. Toggles live in `custom.nix` (the Hub writes them) and `role-state.nix`.
+
+| Module | Default | Purpose |
+|---|---|---|
+| `core/*` | **on** | Roles, Caddy, Njalla, Hub, desktop, perf, ssh-bootstrap |
+| `php.nix`, `credentials.nix` | **on** | Required by web services & secrets |
+| `synapse.nix` | **on** | Matrix homeserver |
+| `wordpress.nix` | **on** | WordPress + PHP-FPM vhost |
+| `nextcloud.nix` | **on** | Files / calendar / contacts |
+| `vaultwarden.nix` | **on** | Bitwarden-compatible secrets vault |
+| `bitcoinecosystem.nix` | **on** | bitcoind/electrs/LND/RTL/BTCPay (over Tor) |
+| `wallet-autoconnect.nix` | **on** | Sparrow/Bisq ↔ node handshake |
+| `haven.nix` | off | Nostr relay |
+| `element-calling.nix` | off | LiveKit + JWT for E2E calling |
+| `mempool.nix` | off | Mempool.space dashboard |
+| `bitcoin-core.nix` | off | Switch node to Bitcoin Core (replaces default Bitcoin Knots + BIP110) |
+| `rdp.nix` | off | xrdp remote desktop |
+| `sshd.nix` | off | Public-facing OpenSSH |
+
+> Tor is wired directly into the Bitcoin stack. In `modules/bitcoinecosystem.nix`, `bitcoind`, `electrs`, and `lnd` all set `tor.enforce = true` and `tor.proxy = true`, and onion services are exposed for them.
+
+## The Three Modes (internal reference)
+
+Selected by `role-state.nix`, resolved by `modules/core/role-logic.nix`. All three configurations are produced from this same flake.
+
+| Mode | What's enabled on top of the base NixOS + GNOME |
+|---|---|
+| **Desktop** | Private daily-driver. Sparrow + Bisq included. |
+| **Node** | Desktop + full Bitcoin stack (bitcoind/electrs/LND/RTL/BTCPay over Tor). |
+| **Server+Desktop** | Node + self-hosting services (Synapse, Nextcloud, WordPress, Vaultwarden, Element Calling, etc.). |
+
+## Build & Deploy Reference
+
+Internal commands. Run from the flake root.
+
+| Action | Command |
+|---|---|
+| Build the System Installer | `nix build .#nixosConfigurations.sovran_systemsos-iso.config.system.build.isoImage` |
+| Switch now | `sudo nixos-rebuild switch --flake .#nixos` |
+| Test in current boot only | `sudo nixos-rebuild test --flake .#nixos` |
+| Stage for next boot | `sudo nixos-rebuild boot --flake .#nixos` |
+| Build only (no activation) | `nixos-rebuild build --flake .#nixos` |
+| Update pinned inputs | `nix flake update` (then rebuild) |
+| Rollback last switch | `sudo nixos-rebuild switch --rollback` |
+| Garbage-collect (>7 days) | Automatic weekly; manual: `sudo nix-collect-garbage -d` |
+
+## Networking & Reverse Proxy
+
+- **Firewall on by default** (`networking.firewall.enable = true`). Port are opened by the module that needs it.
+- **Caddy** (`modules/core/caddy.nix`) terminates TLS for all HTTP services.
+- **Njalla** dynamic DNS (`modules/core/njalla.nix`) keeps records in sync via a 15-minute cron job.
+- **Tor** is enabled with `torsocks` available. The Bitcoin stack uses it directly — see [Security Posture](#security-posture).
+- **SSH:** localhost-only by default (`core/sshd-localhost.nix`).
+  
+## Security Posture
+
+Facts about the defaults, straight from `configuration.nix` and the modules:
+
+- **Reproducible builds.** Every artifact derives from `flake.lock`. The same commit produces the same OS.
+- **Bitcoin stack over Tor.** In `modules/bitcoinecosystem.nix`, `bitcoind`, `electrs`, and `lnd` all set `tor.enforce = true`, and onion services are exposed for `bitcoind`, `electrs`, `lnd`, and friends.
+- **Firewall on, public sshd off, RDP off, auto-login off, fail2bain active**
+- **Kernel surface trimmed.** `boot.blacklistedKernelModules = [ "rxrpc" ];`
+- **Weekly garbage collection** with `--delete-older-than 7d`.
+
+## Backups & Recovery
+
+`services.rsnapshot` snapshots hourly and daily to `/run/media/Second_Drive/BTCEcoandBackup/NixOS_Snapshot_Backup`:
+
+```
+backup  /home/                       localhost/
+backup  /var/lib/                    localhost/
+backup  /etc/nixos/                  localhost/
+backup  /etc/nix-bitcoin-secrets/    localhost/
+retain  hourly  5
+retain  daily   5
+cron    hourly  0  *  *  *  *
+cron    daily   50 21 *  *  *
+```
+
+The second drive is mounted by label (`BTCEcoandBackup`) with `nofail` so a missing drive doesn't block boot.

-# Sovran Hub — Manual Backup
-
-The manual backup service copies critical system data from your Sovran Pro to an external USB drive, providing a third copy of your data (your Sovran Pro already maintains an automatic internal backup on its second drive).
-
-Backups are written to:
-
-```
-<USB drive>/Sovran_SystemsOS_Backup/<timestamp>/
-```
-
-where `<timestamp>` is formatted as `YYYYMMDD_HHMMSS`.
-
---
-
-## Backup Stages
-
-The script always attempts all four stages, but skips stages that are irrelevant to the system's configured role (see [Per-Role Breakdown](#per-role-breakdown) below).
-
-| Stage | Directory | Contents |
-|-------|-----------|----------|
-| **1/4 — NixOS config** | `/etc/nixos/` | Full NixOS system configuration: `role-state.nix`, `custom.nix`, flake files, and any other config managed by the Hub |
-| **2/4 — Secrets** | `/etc/nix-bitcoin-secrets` | Bitcoin/LND secrets stored under `/etc/` |
-| **3/4 — Home directory** | `/home/` | All user home directories (`.cache/` and Trash are excluded) |
-| **4/4 — System data** | `/var/lib/` | Full service data tree, including Vaultwarden, bitcoind, LND, sovran-hub config, domains, secrets, and other `/var/lib` service directories (logs excluded as appropriate) |
-
---
-
-## Per-Role Breakdown
-
-The script detects the system role at runtime by reading `/var/lib/sovran-hub/config.json` (falling back to `/etc/nixos/role-state.nix`) and adjusts its behaviour accordingly.
-
-### Server + Desktop (default)
-
-All services are enabled: Bitcoin, Matrix Synapse, Vaultwarden, WordPress, Nextcloud.
-
-| Stage | Status | Notes |
-|-------|--------|-------|
-| Stage 1 — NixOS config | ✅ Backed up | Full server configuration |
-| Stage 2 — Secrets | ✅ Backed up | `/etc/nix-bitcoin-secrets` |
-| Stage 3 — Home directory | ✅ Backed up | Desktop user data |
-| Stage 4 — System data (`/var/lib`) | ✅ Backed up | Includes Vaultwarden, bitcoind, LND, sovran-hub config, domains, secrets, and all other service data under `/var/lib` (logs excluded) |
-
-This produces the largest backup. All four stages generate meaningful data.
-
-### Desktop Only
-
-All server services are disabled (`bitcoin = false`, `synapse = false`, `vaultwarden = false`, `wordpress = false`, `nextcloud = false`). Only GNOME desktop is active.
-
-| Stage | Status | Notes |
-|-------|--------|-------|
-| Stage 1 — NixOS config | ✅ Backed up | Simpler config (no server services) |
-| Stage 2 — Secrets | ⏭️ Skipped | `/etc/nix-bitcoin-secrets` is not applicable for Desktop Only role |
-| Stage 3 — Home directory | ✅ Backed up | **The most important data for this role** |
-| Stage 4 — System data (`/var/lib`) | ✅ Backed up | Full `/var/lib` backup with `/var/lib/lnd` excluded for Desktop Only role |
-
-This produces the smallest and fastest backup. Stages 1 and 3 are the primary sources of meaningful data.
-
-### Node (Bitcoin-only)
-
-Only the Bitcoin ecosystem is active: `bitcoind`, `electrs`, `lnd`, `rtl`, `btcpay`, `mempool`, and `bip110`. All other server services are disabled.
-
-| Stage | Status | Notes |
-|-------|--------|-------|
-| Stage 1 — NixOS config | ✅ Backed up | Node-specific configuration |
-| Stage 2 — Secrets | ✅ Backed up | `/etc/nix-bitcoin-secrets` |
-| Stage 3 — Home directory | ✅ Backed up | User data |
-| Stage 4 — System data (`/var/lib`) | ✅ Backed up | **Critical** — includes Lightning wallet/channel data plus all other `/var/lib` service data |
-
-All four stages run, matching Server + Desktop behaviour. Some non-Bitcoin service directories under `/var/lib` may be sparse or absent depending on role.
-
---
-
-## Backup Manifest
-
-After all stages complete, the script writes a `BACKUP_MANIFEST.txt` file inside the timestamped backup directory. This file records the date, hostname, detected role, target drive, and a directory listing of everything that was backed up.
-
---
-
-## Running the Backup
-
-The backup is triggered from the Sovran Hub web UI. You can also run it directly:
-
-```bash
-# Auto-detect the first external USB drive
-sudo bash /path/to/sovran-hub-backup.sh
-
-# Specify a target drive explicitly
-sudo BACKUP_TARGET=/run/media/<user>/<drive> bash /path/to/sovran-hub-backup.sh
-```
-
-The script requires at least **10 GB** of free space on the target drive and will refuse to write to internal system drives.
-
-Logs are written to `/var/log/sovran-hub-backup.log` and the current status (`RUNNING`, `SUCCESS`, or `FAILED`) is tracked in `/var/log/sovran-hub-backup.status`.

-This guide covers the Sovran Systems remote deployment system built on [Headscale](https://headscale.net) — a self-hosted, open-source implementation of the Tailscale coordination server. Freshly booted ISOs automatically join a private WireGuard mesh VPN without any per-machine key pre-generation.

-
-**Components:**
- **`sovran-provisioner.nix`** — NixOS module deployed on a separate VPS; runs Headscale + provisioning API + Caddy.
- **Live ISO** (`iso/common.nix`) — Auto-registers with the provisioning server and joins the Tailnet on boot.
- **`remote-deploy.nix`** — Post-install NixOS module that uses Tailscale/Headscale for ongoing access.
-
---
-
-## Part 1: VPS Setup — Deploy `sovran-provisioner.nix`
-
-### Prerequisites
-
- A NixOS VPS (any provider) with a public IP
- Two DNS A records pointing to your VPS:
-  - `hs.yourdomain.com` → VPS IP  (Headscale coordination server)
-  - `prov.yourdomain.com` → VPS IP  (Provisioning API)
- Ports 80, 443 (TCP) and 3478 (UDP, STUN/DERP) open in your VPS firewall
-
-### DNS Records
-
-| Type | Name                  | Value      |
-|------|-----------------------|------------|
-| A    | `hs.yourdomain.com`   | `<VPS IP>` |
-| A    | `prov.yourdomain.com` | `<VPS IP>` |
-
-### NixOS Configuration
-
-Add the following to your VPS's `/etc/nixos/configuration.nix`:
-
-```nix
-{ config, lib, pkgs, ... }:
-
-{
-  imports = [
-    ./hardware-configuration.nix
-    /path/to/sovran-provisioner.nix   # or fetch from the repo
-  ];
-
-  sovranProvisioner = {
-    enable = true;
-    domain        = "prov.yourdomain.com";
-    headscaleDomain = "hs.yourdomain.com";
-
-    # Optional: customise defaults
-    headscaleUser = "sovran-deploy";   # namespace for deploy machines
-    adminUser     = "admin";           # namespace for your workstation
-    keyExpiry     = "1h";              # pre-auth keys expire after 1 hour
-    rateLimitMax  = 10;                # max registrations per window
-    rateLimitWindow = 60;              # window in seconds
-  };
-
-  # Required for Caddy ACME (Let's Encrypt)
-  networking.hostName = "sovran-vps";
-  system.stateVersion = "24.11";
-}
-```
-
-### Deploy
-
-```bash
-nixos-rebuild switch
-```
-
-Caddy will automatically obtain TLS certificates via Let's Encrypt.
-
-### Retrieve the Enrollment Token
-
-```bash
-cat /var/lib/sovran-provisioner/enroll-token
-```
-
-Keep this token secret — it is used to authenticate ISO registrations. The token is auto-generated on first boot and stored at this path. You never need to set it manually. Just `cat` it from the VPS and copy it to `iso/secrets/enroll-token` before building the ISO.
-
---
-
-## Part 2: Admin Workstation Setup
-
-Join your Tailnet as an admin so you can reach deployed machines:
-
-### Install Tailscale
-
-Follow the [Tailscale installation guide](https://tailscale.com/download) for your OS, or on NixOS:
-
-```nix
-services.tailscale.enable = true;
-```
-
-### Join the Tailnet
-
-```bash
-sudo tailscale up --login-server https://hs.yourdomain.com --accept-dns=false
-```
-
-> **Note:** The `--accept-dns=false` flag prevents Tailscale from taking over your system DNS resolver. This is important if you are behind a VPN (see [Troubleshooting](#troubleshooting) below).
-
-Tailscale prints a URL. Open it and copy the node key (starts with `mkey:`).
-
-### Approve the Node in Headscale
-
-On the VPS, first find the numeric user ID for the `admin` user, then register the node:
-
-```bash
-# Look up the numeric ID for the admin user (Headscale 0.28.0 requires -u <id>)
-headscale users list -o json
-
-# Register the node using the numeric user ID
-headscale nodes register -u <admin-user-id> --key mkey:xxxxxxxxxxxxxxxx
-```
-
-Your workstation is now on the Tailnet. You can list nodes:
-
-```bash
-headscale nodes list
-```
-
---
-
-## Part 3: Building the Deploy ISO
-
-### Add Secrets (gitignored)
-
-The secrets directory `iso/secrets/` is gitignored. Populate it before building:
-
-```bash
-# Copy the enrollment token from the VPS
-ssh root@<VPS> cat /var/lib/sovran-provisioner/enroll-token > iso/secrets/enroll-token
-
-# Set the provisioner URL
-echo "https://prov.yourdomain.com" > iso/secrets/provisioner-url
-```
-
-These files are baked into the ISO at build time. If the files are absent the ISO still builds — the auto-provision service exits cleanly with "No enroll token found, skipping auto-provision", leaving DIY users unaffected.
-
-### Build the ISO
-
-```bash
-nix build .#nixosConfigurations.sovran_systemsos-iso.config.system.build.isoImage
-```
-
-The resulting ISO is in `./result/iso/`.
-
---
-
-## Part 4: Deployment Workflow
-
-### Step-by-Step
-
-1. **Hand the ISO to the remote person** — they burn it to a USB drive and boot.
-
-2. **ISO boots and auto-registers** — `sovran-auto-provision.service` runs automatically:
-   - Reads `enroll-token` and `provisioner-url` from `/etc/sovran/`
-   - `POST https://prov.yourdomain.com/register` with hostname + MAC
-   - Receives a Headscale pre-auth key
-   - Runs `tailscale up --login-server=... --authkey=...`
-   - The machine appears in `headscale nodes list` within ~30 seconds
-
-3. **Approve the node (if not using auto-approve)** — on the VPS:
-   ```bash
-   headscale nodes list
-   # Note the node key for the new machine
-   ```
-
-4. **SSH from your workstation** — once the machine is on the Tailnet:
-   ```bash
-   # Get the machine's Tailscale IP
-   headscale nodes list | grep sovran-deploy-
-
-   # SSH in
-   ssh root@100.64.x.x    # password: sovran-remote (live ISO default)
-   ```
-
-5. **Run the headless installer**:
-
-   The `--deploy-key` is your SSH public key that gets injected into `root`'s `authorized_keys` on the deployed machine. This grants full root access for initial setup. Generate it once on your workstation if you haven't already:
-   ```bash
-   ssh-keygen -t ed25519 -f ~/.ssh/sovran-deploy -C "sovran-deploy"
-   ```
-   After deployment is complete and you disable deploy mode, this key is removed.
-
-   ```bash
-   sudo sovran-install-headless.sh \
-     --disk /dev/sda \
-     --role server \
-     --deploy-key "$(cat ~/.ssh/sovran-deploy.pub)" \
-     --headscale-server "https://hs.yourdomain.com" \
-     --headscale-key "$(headscale preauthkeys create -u $(headscale users list -o json | jq -r '.[] | select(.name=="sovran-deploy") | .id') -e 2h -o json | jq -r '.key')"
-   ```
-
-6. **Machine reboots into Sovran_SystemsOS** — `deploy-tailscale-connect.service` runs:
-   - Reads `/var/lib/secrets/headscale-authkey`
-   - Joins the Tailnet with a deterministic hostname (`sovran-<hostname>`)
-
-7. **Post-install SSH and RDP**:
-   ```bash
-   # SSH over Tailnet
-   ssh root@<tailscale-ip>
-
-   # RDP over Tailnet (desktop role) — Sovran_SystemsOS uses GNOME Remote Desktop (native Wayland RDP)
-   # Retrieve the auto-generated RDP password:
-   ssh root@<tailscale-ip> cat /var/lib/gnome-remote-desktop/rdp-password
-   # Then connect with any RDP client (Remmina, GNOME Connections, Microsoft Remote Desktop):
-   #   Host: <tailscale-ip>:3389   User: sovran   Password: <from above>
-   ```
-
-8. **Disable deploy mode** — edit `/etc/nixos/custom.nix` on the target, set `enable = false`, then:
-   ```bash
-   sudo nixos-rebuild switch
-   ```
-
---
-
-## Part 5: Post-Install Access
-
-### SSH
-
-```bash
-# Over Tailnet
-ssh root@100.64.x.x
-```
-
-### RDP (desktop/server roles)
-
-Sovran_SystemsOS uses **GNOME Remote Desktop** (native Wayland RDP — not xfreerdp). The RDP service auto-generates credentials on first boot.
-
-**Username:** `sovran`
-**Password:** auto-generated — retrieve it via SSH:
-```bash
-ssh root@<tailscale-ip> cat /var/lib/gnome-remote-desktop/rdp-password
-```
-
-Connect using any RDP client (Remmina, GNOME Connections, Microsoft Remote Desktop) to `<tailscale-ip>:3389`.
-
---
-
-## Security Model
-
-| Concern | Mitigation |
-|---------|-----------|
-| Enrollment token theft | Token only triggers key generation; it does not grant access to the machine itself |
-| Rogue device joins Tailnet | Visible in `headscale nodes list`; removable instantly with `headscale nodes delete` |
-| Pre-auth key reuse | Keys are ephemeral and expire in 1 hour (configurable via `keyExpiry`) |
-| Rate limiting | Provisioning API limits to 10 registrations/minute by default (configurable) |
-| SSH access | Requires ed25519 key injected at install time; password authentication disabled |
-| Credential storage | Auth key written to `/var/lib/secrets/headscale-authkey` (mode 600) on the installed OS |
-
-### Token Rotation
-
-To rotate the enrollment token:
-
-1. On the VPS:
-   ```bash
-   openssl rand -hex 32 > /var/lib/sovran-provisioner/enroll-token
-   chmod 600 /var/lib/sovran-provisioner/enroll-token
-   ```
-
-2. Update `iso/secrets/enroll-token` and rebuild the ISO.
-
-Old ISOs with the previous token will fail to register (receive 401).
-
---
-
-## Monitoring
-
-### List Active Tailnet Nodes
-
-```bash
-# On the VPS
-headscale nodes list
-```
-
-### List Registered Machines (Provisioning API)
-
-```bash
-curl -s -H "Authorization: Bearer $(cat /var/lib/sovran-provisioner/enroll-token)" \
-  https://prov.yourdomain.com/machines | jq .
-```
-
-### Health Check
-
-```bash
-curl https://prov.yourdomain.com/health
-# {"status": "ok"}
-```
-
-### Provisioner Logs
-
-```bash
-journalctl -u sovran-provisioner -f
-```
-
-### Headscale Logs
-
-```bash
-journalctl -u headscale -f
-```
-
---
-
-## Cleanup
-
-### Remove a Machine from the Tailnet
-
-```bash
-headscale nodes list
-headscale nodes delete --identifier <id>
-```
-
-### Disable Deploy Mode on an Installed Machine
-
-Edit `/etc/nixos/custom.nix`:
-
-```nix
-sovran_systemsOS.deploy.enable = false;
-```
-
-Then rebuild:
-
-```bash
-nixos-rebuild switch
-```
-
-This stops the Tailscale connect service.
-
-### Revoke All Active Pre-Auth Keys
-
-```bash
-# List pre-auth keys (Headscale 0.28.0: no --user flag on list)
-headscale preauthkeys list
-
-# Expire a specific key — use numeric user ID (-u <id>)
-# First find the user ID:
-headscale users list -o json
-# Then expire the key:
-headscale preauthkeys expire -u <user-id> --key <key>
-```
-
---
-
-## Troubleshooting
-
-### VPN Conflicts (Mullvad, WireGuard, etc.)
-
-**Symptom:** `tailscale up` hangs or fails with `connection refused` on port 443, even though `curl https://hs.yourdomain.com/health` works fine.
-
-**Cause:** VPNs like Mullvad route all traffic — including Tailscale's control-plane connections — through the VPN tunnel. Additionally, Tailscale's DNS handler (`--accept-dns=true` by default) hijacks DNS resolution and may prevent correct resolution of your Headscale server even when logged out.
-
-**Solution:**
-1. Disconnect your VPN temporarily and retry `tailscale up`.
-2. If you need the VPN active, use split tunneling to exclude `tailscaled`:
-   ```bash
-   # Mullvad CLI
-   mullvad split-tunnel add $(pidof tailscaled)
-   ```
-   Or in the Mullvad GUI: **Settings → Split tunneling → Add tailscaled**.
-3. Always pass `--accept-dns=false` when enrolling to avoid DNS hijacking:
-   ```bash
-   sudo tailscale up --login-server https://hs.yourdomain.com --authkey <key> --accept-dns=false
-   ```
-
---
-
-### "RATELIMIT" in tailscaled Logs
-
-**Symptom:** `journalctl -u tailscaled` shows lines like:
-```
-[RATELIMIT] format("Received error: %v")
-```
-
-**Cause:** This is **NOT** a server-side rate limit from Headscale. It is tailscaled's internal log suppressor de-duplicating repeated connection-refused error messages. The real underlying error is `connection refused`.
-
-**What to check:**
-1. Is Headscale actually running? `curl https://hs.yourdomain.com/health`
-2. Is your VPN blocking the connection? (see VPN Conflicts above)
-3. Is there a firewall blocking port 443?
-
---
-
-### "connection refused" on Port 443
-
-If `tailscale up` fails but `curl` works, the issue is usually DNS or VPN:
-
-```bash
-# Does curl reach Headscale successfully?
-curl -v https://hs.yourdomain.com/health
-
-# Force IPv4 vs IPv6 to identify if it's an address-family issue
-curl -4 https://hs.yourdomain.com/health
-curl -6 https://hs.yourdomain.com/health
-
-# Check what IP headscale resolves to
-dig +short hs.yourdomain.com
-
-# What resolver is the system using?
-cat /etc/resolv.conf
-```
-
-If curl works but tailscale doesn't, tailscaled may be using a different DNS resolver (e.g. its own `100.100.100.100` stub resolver). Fix: pass `--accept-dns=false`.
-
---
-
-### Headscale User ID Lookup (0.28.0)
-
-Headscale 0.28.0 removed `--user <name>` in favour of `-u <numeric-id>`. To find the numeric ID for a user:
-
-```bash
-headscale users list -o json
-# Output: [{"id": "1", "name": "sovran-deploy", ...}, ...]
-
-# One-liner to get the ID for a specific user
-headscale users list -o json | jq -r '.[] | select(.name=="sovran-deploy") | .id'
-```
-
-Then use the numeric ID in subsequent commands:
-```bash
-headscale preauthkeys create -u 1 -e 1h -o json
-headscale nodes register -u 1 --key mkey:xxxx
-```

-# Tech Support: Security Design, User Flow, and Incident Response
-
-## Overview
-
-The Sovran Hub includes a **Tech Support** feature that lets Sovran Systems
-staff remotely diagnose and fix issues on a user's machine via SSH — without
-ever having access to private keys or wallet funds.
-
-Wallet protection is the default. The user must make an active, time-limited
-choice to grant support staff access to wallet files, and can revoke that
-access at any time.
-
---
-
-## Implementation Details
-
-### Restricted User Instead of Root
-
-When a user enables support access the Hub:
-
-1. Ensures the `sovran-support` system user exists (declared declaratively in
-   `modules/core/tech-support.nix`; the Hub also provisions it on demand as a
-   fallback on non-NixOS systems).
-2. Writes the Sovran Systems public SSH key **only** to
-   `/var/lib/sovran-support/.ssh/authorized_keys`, not to root's
-   `authorized_keys`.
-3. Applies POSIX ACLs (`setfacl -R -m u:sovran-support:---`) to every wallet
-   directory that exists on disk, denying all access by the support user.
-4. Records a timestamped `SUPPORT_ENABLED` event in the audit log at
-   `/var/log/sovran-support-audit.log`.
-
-When the session ends (or if the Hub cannot create the restricted user), the
-key is removed and all ACLs are revoked immediately.
-
-### Protected Wallet Paths
-
-The following directories are locked by default when a support session starts:
-
-| Path | Contents |
-|------|----------|
-| `/etc/nix-bitcoin-secrets` | nix-bitcoin generated secrets |
-| `/var/lib/bitcoind` | Bitcoin Core chainstate and wallet |
-| `/var/lib/lnd` | LND wallet and channel database |
-| `/home` | User home directories |
-
-Paths are only locked if they exist on disk at the time the session starts.
-
-### POSIX ACL Mechanics
-
-POSIX ACLs on Linux handle access checks in this order:
-
-1. If the process UID matches the file owner UID → use owner permissions
-2. **If there is a matching named-user ACL entry → use that entry's
-   permissions** (clamped by the mask entry)
-3. If any group matches → use group permissions
-4. Otherwise → use "other" permissions
-
-Setting `u:sovran-support:---` creates a named-user ACL entry with no
-permissions. Because the named-user entry is checked before the group/other
-entries, the support user cannot access those directories regardless of the
-"other" permission bits.
-
-`setfacl` and `getfacl` are provided by the `acl` package, which is added to
-`environment.systemPackages` by `modules/core/tech-support.nix`.
-
-### Fallback to Root (When Restricted User Cannot Be Created)
-
-If the `sovran-support` user does not exist and cannot be created (e.g.,
-`users.mutableUsers = false` and the declarative module has not been deployed
-yet), the Hub falls back to adding the support key to root's
-`authorized_keys`. The modal prominently warns the user when this has happened
-so they can decide whether to end the session.
-
-### Audit Log
-
-Every session event is appended to `/var/log/sovran-support-audit.log`:
-
-```
-[2025-01-15 14:32:01 UTC] SUPPORT_ENABLED: restricted_user=True acl_applied=True protected_paths=4
-[2025-01-15 14:45:00 UTC] WALLET_UNLOCKED: duration=3600s expires=2025-01-15 15:45:00 UTC
-[2025-01-15 15:45:00 UTC] WALLET_RELOCKED: auto-expired
-[2025-01-15 16:01:22 UTC] SUPPORT_DISABLED
-```
-
-The last 100 lines of this log are accessible from the Hub UI while a session
-is active (or after it ends, until the page is refreshed).
-
---
-
-## Security Tradeoffs
-
-### What This Protects Against
-
- **Accidental wallet exposure** — support staff cannot read wallet files
-  during a normal session; they must ask the user to explicitly grant access.
- **Credential theft** — private keys in the wallet directories are not
-  visible to the `sovran-support` user by default.
- **Scope creep** — the restricted user account limits the blast radius of an
-  SSH session compared to direct root access.
-
-### Known Limitations
-
-| Limitation | Mitigation |
-|------------|------------|
-| Support user still has system-wide bash access | Restrict with `ForceCommand` or AppArmor in the NixOS config if a narrower scope is required |
-| ACLs apply only to directories that exist at session start | If new wallet directories are created during a session, they are not auto-protected. Re-lock and re-enable support to pick up new paths |
-| Root fallback grants full access | The Hub UI warns the user prominently; users should end the session if they are uncomfortable |
-| `setfacl` / ACL filesystem support required | The `acl` package is declared in `tech-support.nix`; most Linux filesystems (ext4, btrfs, xfs) support ACLs by default |
-| Wallet access grant is time-limited but lazy-expired | Expiry is checked on the next `/api/support/status` poll (every 10 seconds in the UI); there is a small window after expiry |
-
-### Defense-in-Depth Recommendations
-
-For environments that require stronger isolation, consider layering one or
-more additional controls:
-
- **`ForceCommand`** in `sshd_config` (or `~/.ssh/authorized_keys` command
-  prefix) to restrict the support user to a specific diagnostic script.
- **`ChrootDirectory`** in the `sshd_config` `Match User sovran-support` block
-  to confine the session to a prepared directory tree.
- **AppArmor or SELinux** profiles that deny the support process read access
-  to wallet paths at the kernel level.
- **Namespace/bind-mount overlays** (e.g., via a wrapper systemd unit) to
-  present a sanitized filesystem view.

-## User Flow
-
-```
-User opens Hub  →  Clicks "Tech Support" in sidebar
-        │
-        ▼
-Modal: "Need help from Sovran Systems?"
-        • Explains what will happen
-        • Shows Wallet Protection notice
-        • User clicks "Enable Support Access"
-        │
-        ▼

-## Incident Response
-
-### Scenario 1 — You accidentally granted wallet access and are unsure what was copied
-
-**Immediate steps:**
-
-1. Click **"Re-lock Wallet Now"** in the Hub modal, or click
-   **"End Support Session"** to simultaneously revoke SSH access and wallet
-   access.
-2. Open the **Audit Log** from the Hub modal and note the timestamps of
-   `WALLET_UNLOCKED` and `WALLET_RELOCKED` events.
-3. Check `/var/log/auth.log` (or `journalctl -u sshd`) for SSH login events
-   by `sovran-support` during the unlocked window.
-
-**Assessment:**
-
- If no SSH login occurred during the wallet-unlocked window, your keys are
-  safe.
- If an SSH login did occur, treat private keys as potentially compromised.
-
-**Recovery if keys may be compromised:**
-
-| Wallet | Recovery action |
-|--------|----------------|
-| LND | Move all funds out using `lncli sendcoins` to a freshly generated on-chain address; close channels; recreate wallet |
-| Sparrow | Sweep funds to a new wallet generated on an air-gapped device |
-| Bisq | Withdraw all BSQ and BTC to external wallets; delete the Bisq data directory and recreate |
-| nix-bitcoin secrets | Rotate all secrets with `nix-bitcoin-secrets generate` and redeploy |
-
-**Report the incident:**
-
-Contact Sovran Systems immediately at support@sovransystems.com with:
- The audit log output (`/var/log/sovran-support-audit.log`)
- The SSH auth log for the affected time window
- A description of what you were troubleshooting
-
---
-
-### Scenario 2 — Support session cannot be ended (button fails or server is unresponsive)
-
-**Manual key removal (run as root on the device):**
-
-```bash
-# Remove from support user's authorized_keys
-rm -f /var/lib/sovran-support/.ssh/authorized_keys
-
-# Remove from root's authorized_keys (fallback / legacy)
-sed -i '/sovransystemsos-support/d' /root/.ssh/authorized_keys
-
-# Remove wallet unlock state
-rm -f /var/lib/secrets/support-wallet-unlock
-
-# Re-apply wallet ACL protections
-setfacl -R -m u:sovran-support:--- /etc/nix-bitcoin-secrets \
-  /var/lib/bitcoind /var/lib/lnd /home 2>/dev/null || true
-
-# Restart sshd to drop any active connections
-systemctl restart sshd
-```
-
---
-
-### Scenario 3 — You see an unexpected SUPPORT_ENABLED in the audit log
-
-This should never happen without physical or remote access to the Hub web
-interface. If you see an unexpected entry:
-
-1. Immediately run the manual key removal commands above.
-2. Change the Sovran Hub web interface password.
-3. Check `/var/log/nginx/access.log` (or Caddy access logs) for unexpected
-   requests to `/api/support/enable`.
-4. Consider rebooting the device to clear any in-memory state.
-5. Report the incident to Sovran Systems.
