-[1.1.1]: https://git.sovransystems.com/Sovran_Systems/Sovran_SystemsOS/releases/tag/v1.1.1
-
-
-## [Unreleased]
-
-### Changed
-  - Replaced Brave Browser with Brave Origin (the new `brave-origin` nixpkgs
-    package) as the desktop's default browser: installed package, dock
-    favorite, Browsers app-folder entry, `xdg.mime.defaultApplications`, and
-    the `$BROWSER` session variable now all point at Brave Origin, and the
-    Sovran Hub launcher runs it.
-  - On installs upgrading from the old Brave package, the desktop theme init
-    now migrates `brave-browser.desktop` → `brave-origin.desktop` in the dock
-    favorites, the Browsers app folder, and the user's `mimeapps.list`, so
-    the dock icon and default-browser handler survive the switch without a
-    manual re-pin.
-
-### Fixed
-  - The Hub launcher now uses a persistent per-user browser profile
-    (`$XDG_STATE_HOME/sovran-hub-browser`) instead of a throwaway `/tmp`
-    profile that was deleted on exit. The throwaway profile wiped the
-    `hub_manual_logout` marker cookie on every close, so `/auto-login`
-    silently logged the user straight back in after they signed out and
-    reopened the Hub window. The persistent profile makes explicit logout
-    stick (until the next password login) while still skipping Brave Origin's
-    one-time startup dialog.
-  - The Hub now redirects to the login page when an API request finds an
-    expired browser session, instead of leaving the dashboard tile grid in a
-    loading state while `/api/services` continues returning 401 every five
-    seconds.
-  - Explicitly logging out now suppresses the desktop launcher's local
-    auto-login after the Hub window is closed and reopened. A successful
-    password login clears that preference.
-  - Sessions are now persisted to `/var/lib/secrets/hub-sessions.json` so the
-    browser login survives the Hub service restart that `nixos-rebuild switch`
-    performs during activation. Previously the in-memory session store was
-    wiped by that restart, the `/api/rebuild/status` poll started returning
-    401, and the rebuild modal spun forever showing "Applying changes…" while
-    the switch result was never displayed.
-  - Rebuild and update modals now bail out and reload the page after sustained
-    polling failures instead of hanging indefinitely.
-  - Rebuild/update scripts stream `nixos-rebuild` output into the live log
-    (it was buffered until completion, making long rebuilds look frozen).

-
-
-## [Unreleased]
-
-### Fixed
- Report the version of the configured BTCPay Server package in the Hub instead of the different package version from unstable nixpkgs.
- Installer VM compatibility: legacy BIOS VM boots now install with GRUB, UEFI VM installs avoid depending on NVRAM boot-entry writes, VM users get clearer disk/resource guidance, and the internet check falls back to HTTPS when ICMP is blocked.
- **Manual Backup now matches the system role**: on the Desktop Only role the Hub's
-  "What gets backed up" list no longer shows Node / Server + Desktop items
-  (nix-bitcoin secrets, `/var/lib` system service data, and the database/blockchain
-  caveats), and the backup script skips those stages entirely — Desktop Only backups
-  now mirror only the NixOS configuration (`/etc/nixos`) and home directory (`/home`).
-  The free-space estimate, stage numbering, backup manifest, and completion message
-  are all role-aware; Node and Server + Desktop backups are unchanged.

-# Contributing to Sovran Systems OS
-
-First off, thank you for considering contributing to Sovran_SystemsOS! 🎉
-
-## Development and Release Repositories
-
-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.
-
-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.
-
-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 Arena.ai to work through significant coding challenges and troubleshooting hurdles. We will continue to use AI to help keep Sovran_SystemsOS stable and maintained.

-
-## Security model
-
-### Local-first operation
-
-The Hub and core data run on operator-owned hardware. The Hub is intended for a
-trusted local network and must not be port-forwarded to the internet. Public
-services, DDNS, software updates, and optional third-party relays require
-external networks and are outside a “fully offline” model.
-
-The local Hub currently uses HTTP. Authentication does not encrypt local network
-traffic, so use a trusted LAN and avoid public or guest Wi-Fi.
-
-### In-repository Bitcoin stack
-
-Bitcoin and Lightning modules are maintained under `modules/bitcoin/`. They were
-adapted from nix-bitcoin, but Sovran builds do not import or fetch nix-bitcoin.
-The `nix-bitcoin.*` option namespace and `/etc/nix-bitcoin-secrets` path remain
-only for upgrade compatibility.
-
-### Supply chain and integrity
-
-`flake.lock` pins flake inputs, and fetched source archives use fixed hashes.
-Builds still depend on pinned Nixpkgs, NixVim, btc-clients-nix, upstream source
-archives, and any configured binary cache. Keeping the Bitcoin modules in this
-repository reduces an external dependency; it does not remove supply-chain
-risk.
-
-The Hub integrity check verifies Nix store contents and compares the running
-system with a build from local `/etc/nixos`. It does not authenticate the release
-publisher or protect against an attacker who already controls root and can
-change both the system and local configuration.
-
-### Access and service isolation
-
- Firewall enabled by default
- Public SSH and remote desktop disabled by default
- Separate service users and systemd sandboxing where supported
- Administrative service ports bound to loopback where practical
- Tor enforced for supported Bitcoin traffic and onion services
- Public web services exposed only when enabled by the operator
-
-Tor reduces network exposure for configured Bitcoin services. It is not a
-guarantee against every IP leak, application bug, or traffic-analysis attack.
-
-### Restricted support access
-
-Support uses a per-session SSH key on the non-root `sovran-support` account.
-Sessions expire after 24 hours and have a small allowlist of `sudo` commands.
-Wallet paths receive deny ACLs unless the operator explicitly removes them.
-Disabling support removes the key and reapplies the ACLs.
-
-Support events are written to `/var/log/sovran-support-audit.log`. This is a
-local audit log, not a cryptographically tamper-evident record.
-
-## Out of scope
-
-Sovran_SystemsOS cannot protect against:
-
- Compromised root or administrator credentials
- Stolen recovery words, private keys, or backups
- Malicious or compromised hardware, firmware, or build infrastructure
- Services the operator deliberately exposes or weakens
- Physical access without appropriate disk and firmware protections
-
-## Operator basics
-
- Verify downloads and stop if the checksum does not match.
- Apply stable security updates promptly.
- Use unique passwords and keep SSH/RDP off when not needed.
- Prefer a well-reviewed hardware signer for meaningful Bitcoin balances.
- Keep tested, offline backups in separate secure locations.
- Never share recovery words or private keys with support.
- Disable support access when the session ends and review the audit log.
-
-No software can provide absolute security. Review your configuration and threat
-model before storing important funds or data.

-
-            IMPORTANT:
-            If you want to expose the mempool frontend to the internet, you
-            should create a custom nginx config that includes TLS, backend caching, rate limiting
-            and performance tuning.
-            For this task, reuse the config snippets from option `services.mempool.frontend.nginxConfig`.

-# ── Server-local domain loopback overrides ────────────────────────────────────
-#
-# Some routers (especially newer ISP-provided devices) do not support NAT
-# loopback (hairpin NAT).  When a request originates on this computer and
-# targets a public domain name that resolves to the router's WAN address, the
-# router may refuse to loop the connection back in — causing Nextcloud, WordPress
-# background jobs, and other server-side callbacks to fail even when the service
-# is fully operational from the internet.
-#
-# This module installs a one-shot systemd service,
-# ``sovran-hosts-update.service``, that reads the configured service domains
-# from ``/var/lib/domains/`` at boot (and whenever triggered by the Hub after a
-# domain is saved) and writes ``127.0.0.1`` entries for them into a dedicated
-# Sovran-managed block in ``/etc/hosts``.
-#
-# With those entries in place:
-#   • Requests originating on this computer resolve the public domain name to
-#     127.0.0.1, reach Caddy directly, and never touch the router.
-#   • Caddy still receives the correct public hostname via TLS SNI so virtual-
-#     host routing and certificate validation continue to work.
-#   • The Sovran Hub can verify Caddy reachability locally without needing NAT
-#     loopback.
-#
-# Limitation: this does not help other devices on your home network (phones,
-# laptops).  Those devices resolve domains via the router's DNS and still depend
-# on NAT loopback (or require manual router DNS overrides).  For now, only
-# server-originated requests benefit from this override.
-#
-# On NixOS, /etc/hosts is normally a symlink into the Nix store and is
-# regenerated by the system activation script.  The ``system.activationScripts``
-# hook below converts it to a writable file each time the system is activated
-# (i.e. after every ``nixos-rebuild switch``) and then injects the Sovran block.

-Subject: [PATCH] allow disabling mining pool fetching in offline environments
-
-Previously, Mempool strictly required fetching mining pool data from
-Github and failed when this was not possible, e.g. in offline
-environments.
-
-This patch allows disabling pool fetching.
-When disabled, empty pool data is inserted into the DB, which
-effectively turns off block pool classification.
