+- Incorrect `lib.mkIf` usage in the NWC wallets module
+- Duplicate systemd LND strings
+- `git fetch` tag-clobber errors against Gitea (now uses `--force`)

 First off, thank you for considering contributing to Sovran_SystemsOS! 🎉
 
-## This Github Repo
+## Development and Release Repositories
 
-This repo is for the development of Sovran_SystemsOS and serves as its connection to the GitHub ecosystem. The main repo for Sovran_SystemsOS is hosted at https://git.sovransystems.com/Sovran_Systems/Sovran_SystemsOS/src/branch/stable. All activity in this GitHub repo is tested and eventually mirrored to the main repo on Gitea, as the ethos of Sovran_SystemsOS is self-sovereignty.
+The GitHub repository is the primary location for Sovran_SystemsOS development
+and collaboration and serves as the project's connection to the GitHub
+ecosystem. Most work is contributed through feature branches and pull requests
+that target GitHub `main`. Development may also begin in a local branch or on
+`staging-dev` at the project's self-hosted Gitea instance:
+https://git.sovransystems.com/Sovran_Systems/Sovran_SystemsOS.
 
-Please note: this repo may contain new features and code not yet in the stable branch on Gitea, and this code is not fully tested.
+GitHub `main` and Gitea `staging-dev` are kept synchronized as the active
+development line, although one may briefly lead the other while changes are
+being integrated. The canonical, release-ready code is maintained on Gitea's
+[`stable` branch](https://git.sovransystems.com/Sovran_Systems/Sovran_SystemsOS/src/branch/stable),
+in keeping with the self-sovereignty ethos of Sovran_SystemsOS.
 
-Moreover, Sovran_SystemsOS has been improved with the help of AI. We have used Copilot to work through significant coding challenges and troubleshooting hurdles. We will continue to use AI to help keep Sovran_SystemsOS stable and maintained.
+The workflow is:
+
+1. Most development and project collaboration — including issues, pull
+   requests, and reviews — happens through GitHub, with completed work
+   integrated into `main`.
+2. Work may also originate locally or on Gitea `staging-dev`. Accepted changes
+   are synchronized between GitHub `main` and Gitea `staging-dev`.
+3. When changes are complete and tested, they are promoted to Gitea `stable`,
+   which is the code used by released Sovran_SystemsOS builds.
+
+Please note: GitHub `main` and Gitea `staging-dev` may contain new features and
+code not yet in `stable`, and that code may not be fully tested.
+
+Moreover, Sovran_SystemsOS has been improved with the help of AI. We have used Copilot and Arean.Ai to work through significant coding challenges and troubleshooting hurdles. We will continue to use AI to help keep Sovran_SystemsOS stable and maintained.

+## Try it first in a virtual machine
+
+**Curious, but not ready to replace your current operating system?** Start with
+Sovran_SystemsOS in a virtual machine (VM). A VM runs Sovran_SystemsOS in a
+window on your existing Windows, macOS, or Linux computer, using a virtual disk
+file instead of your computer's internal drive. You can explore the desktop,
+Sovran Hub, Sparrow, Bisq, and the installation experience before changing how
+you use any physical machine.
+
+This is a low-commitment way to decide whether Sovran_SystemsOS is right for
+you:
+
+- **Keep your current OS.** Closing or deleting the VM leaves the host operating
+  system in place.
+- **Learn at your own pace.** Familiarize yourself with the desktop and tools
+  without needing to make it your daily computer on day one.
+- **Choose your next step with confidence.** When you are ready, install it on
+  a dedicated computer, or keep using the VM as a learning environment.
+
+You can use the same ISO with [VirtualBox](https://www.virtualbox.org), VMware,
+QEMU/KVM, Proxmox, and similar x86_64 VM software. For a first look, select
+**Desktop Only**, allocate at least **8 GB RAM**, and create a **256 GB or
+larger dynamically allocated virtual disk**. The full VM setup and installer
+requirements are in [Installing in a virtual machine](#installing-in-a-virtual-machine-optional).
+
+> **A VM is for evaluation and learning, not a substitute for a dedicated,
+> hardened setup.** Do not use a trial VM to hold meaningful Bitcoin, recovery
+> phrases, passwords, or other sensitive data. Avoid attaching physical drives
+> to the VM, and be deliberate about shared folders, clipboard sharing, and
+> network settings. The installer only changes the disk you select, but you
+> should always review VM disk selections before confirming an install.

+## About Bitcoin wallet entropy
+
+When you create a Bitcoin wallet in Sparrow Wallet, you generate a **24-word
+seed phrase**. You should also apply a **128-bit BIP39 passphrase**. These are
+**two independent entropy sources** — both are required to recover your wallet,
+and neither one alone is sufficient.
+
+**Create each entropy source on different hardware.**
+
+The seed phrase is generated by Sparrow Wallet on your Sovran_SystemsOS machine.
+The 128-bit passphrase should be generated on a separate device — for example:
+
+- A **GrapheneOS** phone using Bitwarden's passphrase generator
+- A different computer running the **Diceware** program
+
+This way, no single device ever produces or holds both sources of randomness.
+If one device is ever compromised, the other entropy source remains unknown to
+an attacker. Your wallet cannot be recovered without **both**.
+
+This is not a recommendation against hardware wallets, dice, or any other
+well-tested method of creating entropy. Those are established and valuable
+approaches. If you use a hardware wallet, verify for yourself that its entropy
+generation — both the software and the hardware — is sound and follows best
+practices.
+
+The takeaway is simply this: **how your entropy is created matters, and
+generating your two entropy sources on two physically separate devices is a
+strong practice to understand before setting up a Bitcoin wallet** with the
+software included in Sovran_SystemsOS.
+
+**You must do your own research.** The information above is basic educational
+context to help you build your own best practices — not financial advice and not
+a substitute for your own due diligence.

+We actively monitor and patch security vulnerabilities in Sovran_SystemsOS. Because the operating system is built on [NixOS](https://nixos.org), stable releases receive security updates backported from upstream Nixpkgs as well as our custom software updates.
+
+| Version | Supported | Notes |
+|:---|:---:|:---|
+| **1.0.x** (Stable) |  Yes | Active stable release line. Patches are backported regularly. |
+| **staging-dev** |  Yes | Development line; updated frequently but may contain untested code. |
+| **Legacy (< 1.0.0)** |  No | Please upgrade to the latest stable release to ensure you have active security updates. |
+
+---
+
+## 2. Reporting a Vulnerability
+
+We take the security of self-custody systems, private clouds, and communications servers extremely seriously. If you discover a vulnerability, **please do not open a public issue, forum thread, or submit a public pull request.** 
+
+Instead, report vulnerabilities privately through one of the following secure channels:
+
+1. **Email:** Send an encrypted or plain-text email to [support@sovransystems.com](mailto:support@sovransystems.com).
+   - If sending sensitive information, please contact us first to establish a secure PGP-encrypted communication channel.
+2. **GitHub Private Vulnerability Reporting:** If you are viewing this on GitHub, you can report vulnerabilities privately via the **Security** tab of this repository under **Vulnerability reporting**.
+
+### What to Include in a Report:
+To help us triage and resolve the issue quickly, please include:
+- A clear description of the vulnerability and its potential impact.
+- Step-by-step instructions to reproduce the issue (including any scripts or configuration snippets).
+- The version of Sovran_SystemsOS you tested (found in the Hub header or `/etc/nixos/VERSION`).
+- Any potential remediation steps or suggestions you may have.
+
+### Our Response and Disclosure Process:
+1. **Acknowledgment:** We will acknowledge receipt of your report within **24–48 hours** and provide a tracking reference.
+2. **Triage:** We will investigate and verify the vulnerability privately. We may reach out to you for clarifying details.
+3. **Remediation:** If verified, we will develop a patch on a private security branch.
+4. **Release:** We will coordinate a release date with you and publish the patch to Gitea `stable` and GitHub `main`.
+5. **Advisory:** A public security advisory will be published, giving full credit to you for the discovery (unless you request anonymity).
+
+We ask that you practice **coordinated vulnerability disclosure**, giving us reasonable time to patch the vulnerability before disclosing it publicly to protect other operators' funds and data.
+
+---
+
+## 3. The Sovran_SystemsOS Security Architecture
+
+Understanding our underlying threat model and architectural decisions will help you evaluate the system's security.
+
+### A. Local-First Threat Model
+- **No Cloud Dependency:** Your data, keys, and credentials live entirely on your physical hardware.
+- **Local network Hub Access:** The Sovran Hub is served directly on your local network (`sovransystemsos.local`). It is protected by authentication and **never** automatically exposed to the public internet.
+- **Localhost Auto-Login:** Auto-login to the Hub is restricted strictly to local connections from `127.0.0.1` or `::1` (e.g., when accessing it directly from the local GNOME desktop). LAN and WAN clients must authenticate via password.
+
+### B. Declarative & Reproducible NixOS Foundation
+- **No Supply Chain Drift:** Dependencies, packages, and system components are strictly pinned using Nix flakes (`flake.lock`).
+- **Reproducible Integrity Checks:** Operators can verify system integrity at any time via the Hub (`/api/security/verify-integrity`), which runs `nix store verify --all` to check binary consistency and rebuilds the system state from local files to guarantee it matches the expected configuration.
+- **Default-Hardened Base:** Firewalls are enabled by default (`networking.firewall.enable = true`), public SSH and remote desktop are disabled by default, and legacy kernel modules like `rxrpc` are blacklisted to reduce the kernel's attack surface.
+
+### C. Restricted Tech Support ("Zero-Trust Support")
+To prevent support staff or malicious actors from accessing your private wallets, the operating system employs a unique **"Zero-Trust Support"** architecture:
+- **Restricted System Account:** Support sessions use a restricted, non-root account (`sovran-support`) with heavily scoped shell access and limited `sudo` privileges (restricted strictly to viewing logs, editing configuration, and rebuilding or restarting services).
+- **POSIX ACL Wallet Lockout:** Enabling support immediately triggers POSIX ACLs (`setfacl -m u:sovran-support:---`) to block the support user from reading, writing, or traversing sensitive directories (such as `/etc/nix-bitcoin-secrets`, `/var/lib/bitcoind`, `/var/lib/lnd`, and `/home`).
+- **User-Controlled Timed Unlock:** Support staff can *only* access wallet files if the operator explicitly grants a time-limited unlock from the Hub interface. This unlock automatically expires, re-locking the directories.
+- **Tamper-Evident Auditing:** All support actions (enabling, disabling, wallet unlocking, or locking) are logged in a tamper-evident audit trail (`/var/log/sovran-support-audit.log`) readable directly by the operator.
+
+### D. Native Cryptographic Isolation
+- **Tor Network Integration:** Upstream Bitcoin services (Knots/Core, Electrs, LND) utilize native Tor integration, preventing your home IP address from leaking to the public network or third-party node providers.
+- **Isolated Lightning Wallets:** Nostr Wallet Connect (NWC) uses isolated, sandboxed Lightning wallets with specific spending limits and access presets (e.g., receive-only), keeping your main node funds completely isolated from individual apps.
+
+---
+
+## 4. Security Best Practices for Operators (Users)
+
+No software can provide absolute security. You are the ultimate sovereign of your machine. Follow these best practices to keep your system and assets secure:
+
+### 🔑 1. Split Wallet Entropy
+When setting up a Bitcoin wallet, **generate your two entropy sources on separate, unconnected hardware**:
+- **Seed Phrase:** Generated by Sparrow Wallet on your Sovran_SystemsOS machine.
+- **BIP-39 Passphrase (128-bit):** Generated on a separate device (e.g., a GrapheneOS phone using a trusted password generator or offline Diceware dice).
+- *Why?* If either device is compromised, your wallet remains secure because an attacker needs **both** independent sources of randomness to recover it.
+
+### 💾 2. Implement a Robust Backup Strategy
+- **Off-Machine Backups:** Never store your only wallet backups, seed phrases, or descriptor backups on the same computer as your running wallet.
+- **Descriptor & Channel Backups:** If using Lightning (LND), regularly back up your Static Channel Backups (SCB) and store them off-site. A node hardware failure can permanently lock up channel funds without a fresh SCB.
+- **Ext4 Backups:** If using the Hub's Manual Backup utility, ensure you are backing up to a dedicated **ext4-formatted** external drive. This preserves Linux-native security metadata, permissions, and POSIX ACLs.
+
+### 🛡️ 3. Maintain Network and Access Hygiene
+- **Public SSH Off:** Keep SSH remote access disabled in the Hub unless you actively need it. If enabled, Fail2Ban is active, but you should still enforce a strong system password.
+- **Strong Diceware Passwords:** Ensure the system `free` and `root` users have strong passphrases. Avoid re-using passwords across services.
+- **Guest Networks:** Do not access the Sovran Hub over public or guest Wi-Fi networks. These networks often lack isolation, exposing local network traffic to other devices.
+- **Disable RDP When Done:** Turn off Remote Desktop (RDP) once your administrative session is finished.
+
+### 🧑‍💻 4. Hardening Support Sessions
+If you require technical support from Sovran Systems:
+- **Enable SSH and Support on-demand:** Only enable SSH Remote Access and Support sessions when actively working with a technician, and **disable** them immediately when the session is over.
+- **Confirm Removal:** The Hub's support page includes a "Verify Removal" feature. Always use it to ensure public keys have been fully stripped from the system.
+- **Restrict Wallet Access:** Only unlock your wallet directories if absolutely necessary for the support session, and choose the shortest possible duration. Re-lock manually as soon as the troubleshooting steps are complete.
+- **Review Audit Logs:** Periodically inspect the support audit log via the Hub interface to review exactly when support sessions were toggled or unlocked.
