DannyDannyDanny d4dbd73a8c feat(nixos): add phantom-ship host and streamline server installer ✨

- New host config: phantom-ship.nix (SSH, auto-rebuild, nix-ld, Ethernet)
- Hardware stub: phantom-ship-hardware.nix (replaced by install script)
- Add phantom-ship to flake.nix with home-manager
- Install script now auto-provisions post-install:
  - Clones dotfiles to /etc/dotfiles
  - Installs SSH public key (SSH_PUBKEY_FILE env var)
  - Generates hardware config
  - Supports INSTALLER_HOSTNAME and INSTALLER_DISK env vars
- Fix bootstrap-install.sh default branch to main
- Update CLAUDE.md and server-installer-usb.md

Build commands

# macOS (from ~/dotfiles/nixos)
darwin-rebuild switch --flake .

# NixOS servers (SSH from mac, or on server)
sudo nixos-rebuild switch --flake .#sunken-ship
sudo nixos-rebuild switch --flake .#phantom-ship

# WSL
sudo nixos-rebuild switch --flake ~/dotfiles/nixos#wsl

# Update flake + rebuild (fish alias: nixupdate)
cd ~/dotfiles/nixos && sudo nix flake update && sudo darwin-rebuild switch --flake ~/dotfiles/nixos#Daniel-Macbook-Air

# Installer ISO (Linux only, cannot build on macOS)
cd ~/dotfiles/nixos && nix build .#installer-iso

Rebuild protocol

Never run rebuild commands automatically. When changing Nix config files, always ask the user to rebuild first. Do not assume packages are available until after a successful rebuild.

Flake architecture

Flake: nixos/flake.nix — single flake for all hosts
Inputs: nixpkgs-unstable, nix-darwin, home-manager, nixos-wsl, disko, zen-browser
Host configs in nixos/hosts/:
- daniel-macbook-air.nix — hostname Daniel-Macbook-Air (aarch64-darwin, nix-darwin)
- sunken-ship.nix — NixOS home server (x86_64-linux, WiFi + AirPlay)
- phantom-ship.nix — NixOS home server (x86_64-linux, Ethernet)
- wsl.nix — WSL (x86_64-linux)
- server-install.nix — disko-install target (LUKS)
Home Manager: integrated on macOS, WSL, and sunken-ship; user config in nixos/home/danny/home.nix
Shared modules: nixos/fish.nix (fish + bash), nixos/ollama.nix
Darwin config name: Daniel-Macbook-Air (must match in rebuild commands)

Repo rules

Public repo — no keys, tokens, or identifying secrets. Use scp or config outside the repo.
SSH keys: one key per purpose (e.g. id_ed25519_github, id_ed25519_servers). Use IdentityFile + IdentitiesOnly yes in ~/.ssh/config. Keys stay outside the repo.
Commit and push before testing on sunken-ship — the server clones/pulls from origin.

Server (sunken-ship)

SSH: ssh -i ~/.ssh/id_ed25519_sunken_ship danny@sunken-ship
Remote rebuild: ssh ... 'cd /etc/dotfiles/nixos && sudo nixos-rebuild switch --flake .#sunken-ship'
Auto-rebuild timer: dotfiles-rebuild — every 15 min. Check with systemctl is-active dotfiles-rebuild.timer.
WiFi connected; stays reachable when ethernet is unplugged.
Services: UxPlay (AirPlay receiver on Scarlett Solo)

Server (phantom-ship)

SSH: ssh danny@phantom-ship
Remote rebuild: ssh ... 'cd /etc/dotfiles/nixos && sudo nixos-rebuild switch --flake .#phantom-ship'
Auto-rebuild timer: same pattern as sunken-ship.
Ethernet only (no WiFi).

Ollama

Custom nix-darwin module at nixos/ollama.nix (upstream PR not yet merged). Enabled on macOS via nixos/hosts/daniel-macbook-air.nix. Runs as a launchd user agent with ollama serve.

Alacritty (macOS)

Terminal colors follow System Settings → Appearance: programs.alacritty imports ~/.config/alacritty/active-colors.toml; scripts/alacritty-sync-system-theme.sh copies Catppuccin latte/mocha there when the OS mode changes. nix-darwin launchd.user.agents.alacritty-system-theme polls every 30s; fish runs the same script on interactive startup. After changing Nix, one darwin-rebuild switch. Details: assets/alacritty/README.md.

Shell

Fish is the default shell. Bash auto-execs fish unless the parent process is already fish. Vi keybindings with fzf integration. Zoxide aliased to cd.
