+# gbook
+
+`gbook` is a personal laptop/workstation running Arch Linux.
+
+## Identity
+
+- Inventory id: `gbook`.
+- Hostname: `gbook`.
+- OS: Arch Linux.
+- IP assignment: dynamic.
+
+## Network
+
+The laptop does not have a static IP address.
+
+Observed addresses:
+
+- `192.168.1.76` on `home-lan`, observed 2026-05-10.
+- `192.168.2.49` appeared in pfSense ARP with the same MAC, but this needs confirmation before being treated as a normal operating address.
+
+Agents should identify this device by hostname and owner context first, not by a fixed address.
+
+## Observed Services
+
+Observed on `192.168.1.76`:
+
+- SSH on TCP `22`, OpenSSH 10.2.
+- HTTP on TCP `80`, Apache httpd 2.4.66 with PHP 8.5.4.
+- Ajenti on TCP `5000`.
+
+## Documentation Policy
+
+Because this is a personal laptop with dynamic addressing, document:
+
+- stable hostname;
+- OS family and role;
+- intentionally exposed local services;
+- SSH access method if the owner explicitly wants agents to use it.
+
+Do not treat the current IP address as stable, and do not document local user passwords, private keys, browser sessions, or personal data paths.

+
+The Arch Linux laptop `gbook` does not have a static IP address.
+
+Current observed candidate on `home-lan`:
+
+- Address: `192.168.1.76`.
+- SSH on TCP `22`, OpenSSH 10.2.
+- HTTP on TCP `80`, Apache httpd 2.4.66 with PHP 8.5.4.
+- Ajenti on TCP `5000`.

+pfSense ARP also showed the same MAC on `192.168.2.49`, but that IoT-network presence needs confirmation before treating it as a normal operating address.
