First boot: the machine asks, you answer.

• The full name you want attached to the administrator account; it is asked before the account is created.
• Two passwords, chosen and remembered: root's, which commits setup permanently, and your own user's.
• For each wired interface, an answer: IPv4 (DHCP, static or off), IPv6 if you want it, plus DNS servers and the package repository URL.
• A few minutes of console attention: the prompts are short and plain, and once setup finishes the machine reboots straight into the configured system.

The wizard owns the console after platform boot work completes: bootloader, kernel, real root, init, then the boot-level platform services, and only then the setup prompts on a console that has finished printing. On OpenRC it runs in the boot runlevel; on systemd a gate holds the multi-user transaction until setup completes. Either way the operational system (gettys, sshd, firewall, network) starts only after setup.

• The root password is set first and is the commit point: from that moment setup will not run again on any later boot, whatever else is still unconfigured.
• An administrator account is created (member of wheel, /bin/bash shell) with its own password, after a full name is recorded.
• Every wired interface is walked in turn: IPv4 mode (DHCP, static or off) is asked first, then whether IPv6 is wanted and its mode. Nothing is applied until every interface has been answered, and stepping back re-asks instead of carrying a mistake forward.
• Wireless interfaces are skipped: automatic wireless setup is not implemented, so Wi-Fi is configured by hand after first boot.
• DNS servers and the package repository URL are chosen; login shell defaults are installed; the machine identity is minted; SSH host keys are ensured best-effort (the SSH daemon's own first start regenerates anything missing, so a failure here is repaired later and is not reported as incomplete setup).
• Every step gets at most three attempts, then is recorded as unfinished rather than looping forever; anything skipped stays visibly listed with how to finish it by hand. Setup cannot be re-armed and never re-runs.
• When the run was launched by the boot path, the machine reboots straight into the configured system; a manual run simply exits without rebooting a live machine.

• No hostname prompt: the hostname was baked at build time (--hostname, defaulting to saphira or saphirad by init system).
• No locale or timezone prompts: those are post-install concerns, configured on the running system.
• No graphical anything: the wizard is plain console text, deliberately dependency-free, because it must run before any terminal type is meaningful.
• No second boot mode: first boot is an init-level concern, never a bootloader selection. The boot menu carries no setup entry.
