updated sovran-bitcon

The Hub vendored a second copy of the NWC stack
(app/sovran_systemsos_web/nwc_hub_manager.py, nwc_audit.py,
nwc_lnurl_service.py, nwc_wallet_cli.py) and built its own nwc-wallet /
nwc-lnurl binaries from it. That copy drifted from the pinned Alby Hub
API contract (appId vs toAppId) and duplicated code that Sovran_Bitcoin
already ships and fixes.

Changes:
- Delete the four vendored modules; server.py now imports the canonical
  implementation directly (from sovran_nwc import nwc_hub_manager) from
  the sovran-nwc package (pkgs.sovran-bitcoin.nwc). API fixes in
  Sovran_Bitcoin now propagate to the Hub web app automatically.
- sovran-hub-web launcher: add <sovran-nwc>/lib/sovran-nwc to
  sys.path so the import resolves.
- Stop shipping nwc-wallet / nwc-lnurl binaries from sovran-hub-web:
  the flake already provides them (env-wrapped nwc-wallet with
  NWC_* vars via albyhub.nix, and nwc-lnurl.service via lnurl.nix).

Requires a Sovran_Bitcoin rev containing the toAppId fix (and the
LNURL module audit-log fix); bump the flake input afterwards:
  nix flake update sovran-bitcoin

Test:
  - nixos-rebuild switch
  - Hub Wallet Connections tab still lists/creates wallets
  - nwc-wallet list works from the operator shell
  - journalctl -u nwc-lnurl shows no import/contract errors

+
+## [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 `$BROWSER` session variable now all point at Brave Origin, and the
+    Sovran Hub launcher runs it.
+  - On installs upgrading from the old Brave package, the desktop theme init
+    now migrates `brave-browser.desktop` → `brave-origin.desktop` in the dock
+    favorites, the Browsers app folder, and the user's `mimeapps.list`, so
+    the dock icon and default-browser handler survive the switch without a
+    manual re-pin.
+
+### Fixed
+  - Zeus Connect QR in the Hub was invalid: the LND-only `lndconnect`
+    wrapper used flags Zeus/`lndconnect` do not understand (`--cert`,
+    `--macaroon`), read a non-existent onion path (`free/lnd.onion`),
+    and collided with LND's P2P hidden service. The wrapper now matches
+    the nix-bitcoin contract — dedicated `lnd-rest` onion on port 8080,
+    `--nocert` over Tor, admin macaroon in the URI — so scanning the Hub
+    QR in Zeus works again.
+  - The Hub launcher now uses a persistent per-user browser profile
+    (`$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).
+  - The update modal now reconciles persisted update state after a page/RDP
+    reconnect, bounds every status request with a timeout, prevents overlapping
+    async polls, and reports an explicit "status unavailable" state with a
+    Retry Status action instead of spinning forever. Verbose Nix logs are
+    rendered incrementally and bounded so they cannot stall the browser UI.
+  - Successful staged updates now record the exact NixOS generation. The Hub
+    keeps showing "Restart required" until that generation is active, then
+    clears the marker after reboot (with log-based recovery for older updates).
+  - Pending-reboot state is now derived from NixOS itself — the boot default
+    (`/nix/var/nix/profiles/system`) versus the running `/run/current-system`
+    — instead of from Hub-written marker files. Updates performed from a
+    terminal or support session (which never touch the Hub's status files)
+    previously left a stale `REBOOT_REQUIRED` marker the Hub could never
+    clear, pinning the "Restart required" badge forever even after many
+    reboots. The marker self-heals to `IDLE` on the next status read whenever
+    boot default and running system agree, and recording the informational
+    `.generation` marker can no longer fail an otherwise successful update.

 ## About Bitcoin wallet entropy
 
-When you create a Bitcoin wallet in Sparrow Wallet, you generate a **24-word
+Wallet recovery words control the funds. Never share them with a website,
-seed phrase**. You should also apply a **128-bit BIP39 passphrase**. These are
+support technician, cloud service, or chat application.
-**two independent entropy sources** — both are required to recover your wallet,
-and neither one alone is sufficient.
 
-**Create each entropy source on different hardware.**
+For meaningful balances, prefer a well-reviewed hardware signer and follow its
+verified backup process. A BIP39 passphrase is optional, advanced protection;
+it is not a replacement for the recovery words. If you use one, back it up
+separately—losing either item can make the wallet unrecoverable.
 
-The seed phrase is generated by Sparrow Wallet on your Sovran_SystemsOS machine.
+Keep durable offline backups in separate secure locations. Test recovery before
-The 128-bit passphrase should be generated on a separate device — for example:
+relying on a wallet, and begin with a small amount.
-
-- 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.

 ## Security approach
 
-Sovran_SystemsOS is designed around local ownership and explicit control.
+Sovran_SystemsOS uses layered controls:
 
-Its security foundations include:
+- Pinned flake inputs and hash-pinned source archives
+- Bitcoin and Lightning modules maintained in this repository
+- Firewall enabled; public SSH and remote desktop disabled by default
+- Separate service users, systemd sandboxing, and loopback bindings where practical
+- Tor enforcement for supported Bitcoin services
+- Restricted, time-limited support access with scoped `sudo`
+- Operator-controlled public service exposure
 
-- Reproducible builds from pinned flake inputs
+See [`SECURITY.md`](SECURITY.md) for the threat model, limitations, reporting,
-- Firewall enabled by default
+and operator guidance. No operating system can protect funds after recovery
-- Public SSH disabled by default
+words, administrator credentials, or the root account are compromised. Apply
-- Remote desktop disabled by default
+updates and keep tested offline backups.
-- Hub authentication
-- Local-network Hub access through `sovransystemsos.local`
-- Tor integration for the Bitcoin stack
-- User-controlled service exposure
-- Declarative system configuration
-- Restricted technical-support access
-- Auditable open-source code
-
-No operating system can guarantee complete security. Users should still apply
-updates, protect credentials, maintain backups, secure their local network,
-and review any services they choose to expose publicly.
-
-Bitcoin users must also securely back up wallet seed phrases, descriptors,
-channel backups, and other recovery information. Never store your only wallet
-backup on the same computer that holds the wallet.

+### Bitcoin stack
 
----
+Bitcoin and Lightning modules are maintained in the standalone
+[Sovran_Bitcoin](https://github.com/naturallaw777/Sovran_Bitcoin) repository
+and consumed as a flake input. OS-specific customizations (Second_Drive paths,
+operator user, Hub integration) are bridged by
+`modules/sovran-bitcoin-integration.nix`. The `nix-bitcoin.*` option namespace
+and `/etc/nix-bitcoin-secrets` path remain only for upgrade compatibility.
 
-## 3. The Sovran_SystemsOS Security Architecture
+### Supply chain and integrity
 
-Understanding our underlying threat model and architectural decisions will help you evaluate the system's security.
+`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.
 
-### A. Local-First Threat Model
+The Hub integrity check verifies Nix store contents and compares the running
-- **No Cloud Dependency:** Your data, keys, and credentials live entirely on your physical hardware.
+system with a build from local `/etc/nixos`. It does not authenticate the release
-- **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.
+publisher or protect against an attacker who already controls root and can
-- **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.
+change both the system and local configuration.
 
-### B. Declarative & Reproducible NixOS Foundation
+### Access and service isolation
-- **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")
+- Firewall enabled by default
-To prevent support staff or malicious actors from accessing your private wallets, the operating system employs a unique **"Zero-Trust Support"** architecture:
+- Public SSH and remote desktop disabled by default
-- **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).
+- Separate service users and systemd sandboxing where supported
-- **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`).
+- Administrative service ports bound to loopback where practical
-- **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.
+- Tor enforced for supported Bitcoin traffic and onion services
-- **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.
+- Public web services exposed only when enabled by the operator
 
-### D. Native Cryptographic Isolation
+Tor reduces network exposure for configured Bitcoin services. It is not a
-- **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.
+guarantee against every IP leak, application bug, or traffic-analysis attack.
-- **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.
 
----
+### Restricted support access
 
-## 4. Security Best Practices for Operators (Users)
+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.
 
-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:
+Support events are written to `/var/log/sovran-support-audit.log`. This is a
+local audit log, not a cryptographically tamper-evident record.
 
-### 🔑 1. Split Wallet Entropy
+## Out of scope
-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
+Sovran_SystemsOS cannot protect against:
-- **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
+- Compromised root or administrator credentials
-- **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.
+- Stolen recovery words, private keys, or backups
-- **Strong Diceware Passwords:** Ensure the system `free` and `root` users have strong passphrases. Avoid re-using passwords across services.
+- Malicious or compromised hardware, firmware, or build infrastructure
-- **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.
+- Services the operator deliberately exposes or weakens
-- **Disable RDP When Done:** Turn off Remote Desktop (RDP) once your administrative session is finished.
+- Physical access without appropriate disk and firmware protections
 
-### 🧑‍💻 4. Hardening Support Sessions
+## Operator basics
-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.
 
----
+- 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.
 
-Thank you for helping us maintain a highly secure, private, and sovereign computing operating system!
+No software can provide absolute security. Review your configuration and threat
+model before storing important funds or data.

+
+The ONLY reliable indicator that a reboot is pending is NixOS itself: the
+system profile (``/nix/var/nix/profiles/system``), which ``nixos-rebuild``
+points at the newest generation on every ``boot`` AND every ``switch``, versus
+``/run/current-system``, the generation actually running since the last boot.
+When the two differ, a staged generation has not been booted yet.

+``REBOOT_REQUIRED`` status was written by an updater older than the marker
+feature — left the Hub showing "Restart required" forever: the recorded

+# ── Unified public-IP detection (privacy-first) ─────────────────────────────
+#
+# One script, one cache file, every consumer on the system reads the same
+# value. Previously the public IP was detected independently in three places,
+# each phoning home to a different third party:
+#   * the Hub (server.py _get_external_ip) → api.ipify.org / ifconfig.me /
+#     icanhazip.com over HTTPS on every /api/network call and every
+#     background-loop tick
+#   * DDNS (ddns-update.py) → myip.opendns.com via OpenDNS
+#   * LiveKit → STUN (its own embedded detection)
+#
+# This module replaces all of that with a single script
+# (/var/lib/sovran/public-ip.py) that detects the IP once per TTL using the
+# least-exposing mechanism available, and caches it in
+# /var/lib/secrets/external-ip. Consumers (Hub, DDNS, LiveKit) read the cache
+# and only invoke the script when it is missing or stale.
+#
+# Detection chain (first success wins, stops immediately):
+#   1. pin         — sovran_systemsOS.elementCalling.externalIP (baked in)
+#   2. cache       — /var/lib/secrets/external-ip if newer than cacheTTL
+#   3. STUN        — UDP binding request (one packet, no application data,
+#                    no HTTP metadata; the same protocol every WebRTC client
+#                    uses). Server configurable via publicIP.stunServer.
+#   4. DNS         — "myip.opendns.com" A query via publicIP.dnsResolver
+#                    (single DNS query, no HTTP headers)

+"""Sovran restricted journal helper.
+
+A root-owned, non-user-writable diagnostic tool that wraps journalctl with
+a strict allowlist of safe flags.  Replaces the ``journalctl *`` sudo rule
+in tech-support.nix.
+
+Accepted flags:
+  --unit / -u <name>        must be one of the explicitly approved service units
+  --lines / -n <N>          positive integer (max 10000)
+  --priority / -p <level>   0-7 or emerg/alert/crit/err/warning/notice/info/debug
+  --since <datetime>        ISO 8601 date/datetime (no paths, no filesystem roots)
+  --until <datetime>        ISO 8601 date/datetime (no paths, no filesystem roots)
+  --output / -o <format>    short | short-iso | cat | json | verbose
+
+At least one ``--unit`` flag is required; whole-journal queries are rejected.
+All other flags, paths, directories, roots, namespaces, and output
+destinations are rejected with a non-zero exit code.
