Cut restated "what", domain-glossary framing, cross-file consumption
narration, and against-alternative justification from in-file comments;
keep only non-obvious "why" and load-bearing pointers. Drop the
`generateCompletions` line (a no-op restatement of the upstream default)
and its comment.
Install Claude Code through home-manager's native programs.claude-code
module, matching how the tmux and fish Modules use their home-manager
options rather than a raw home.packages entry. The feature Module at
modules/claude-code/claude-code.nix stays thin — just the enable option
and the delegation — and writes no settings, so login and first-run
configuration remain interactive and no auth material enters the repo.
Signing in without a browser (needed over the console or SSH) is
documented in modules/claude-code/authentication.md: the paste-code OAuth
flow, where the printed URL is opened on another device and the code
pasted back, and the ANTHROPIC_API_KEY path for non-interactive use.
The neogaia toplevel builds with claude-code-2.1.209 included.
Add an nvim Module that configures Neovim declaratively through nixvim,
wired as a flake input and consumed as its home-manager module. Options,
globals, keymaps, and plugin settings are typed Nix; the colorscheme
call and two autocmds live in modules/nvim/config.lua via extraConfigLua.
Plugins come from nixpkgs (no plugin manager, no runtime cloning); git,
ripgrep, and fd are provided from Nix; treesitter grammars are built by
Nix so no runtime compiler is needed.
Functionally matches the previous config (plugins, keymaps, options, the
nord colorscheme, markdown conceal, the Neogit blame toggle), verified
headless against the generated init.
Configure tmux through home-manager's programs.tmux: the settings it exposes
as options (prefix, keyMode, mouse, baseIndex, clock24, escapeTime,
historyLimit, terminal) are set as options, and every setting it has no option
for is read verbatim from modules/tmux/extra.conf. No tmux plugin manager is
used. The generated config is behaviourally identical to the reference, verified
by parsing it with a live tmux binary.
Move the login-shell switch behind a new modules.fish.defaultShell
option (default false; neogaia opts in). Convert every non-eza alias to
an abbreviation, set preferAbbrs and pin generateCompletions, and switch
the command line to vi-style editing. Cap navigation at four dots and
drop psmem/psmem10/dir/vdir/please. Comment the installed packages.
Translate the CachyOS fish snapshot into a home-manager Module: the
fastfetch greeting, the bat-backed manpager, the done and bang-bang
plugins (from nixpkgs, not a plugin manager), the history/backup/copy
helper functions, and the eza and navigation aliases. Pacman-specific
aliases are dropped or replaced with NixOS equivalents (update ->
nixos-rebuild switch, cleanup -> nix-collect-garbage). Enabling the
Module also makes fish the user's default login shell.
Turn the booted laptop into a usable, remotely reachable console: enable
NetworkManager so wifi can be joined from the console and an SSH daemon so
the rest of the setup can be driven over the network. Set the base locale to
timezone America/New_York, locale en_GB.UTF-8, and console keymap us.
These live inline in the neogaia Host rather than behind enable Modules,
matching the single-Host MVI precedent; a shared locale/networking Module can
be extracted once a second Host needs the same settings. SSH keeps default
password auth on, as first-boot access relies on the hand-set bootstrap
password until key/sops-based auth lands post-install.
Remove modules/zram.nix — it only wrapped the native zramSwap.enable toggle
without adding anything — and enable zram inline on neogaia instead. Rewrite
the touched comments to describe only the current file content, and record
the in-file-comment convention in CLAUDE.md.
Select the CachyOS kernel per-Host via boot.kernelPackages, enable Intel
microcode and redistributable firmware (ath10k for the QCA6174 wifi), and
move zram behind a toggle Module. Declare the chaotic binary cache in the
base Nix settings (extra-substituters/keys) so the built system fetches the
kernel from nyx-cache rather than compiling it.
Add disko as a flake input (following nixpkgs) and wire its NixOS module
into the host-builder, so any Host can declare a disk layout while the
layout itself stays a per-Host concern.
neogaia's layout (hosts/neogaia/disk.nix): one GPT NVMe disk with a
systemd-boot EFI system partition and a LUKS container holding btrfs with
@root/@home/@nix subvolumes. The initrd prompts for the passphrase on a
normal boot. Swap is RAM-backed zram, so there is no on-disk swap
partition; zramSwap is enabled directly for now (task 0003 lifts it into
a toggle Module). The task-0001 placeholder fileSystems are removed since
disko now derives them.
Address PR review feedback: in-file comments should describe only what the
file currently is, not task numbers, external tooling, or past/future states.
- hosts/neogaia: drop the "replaced by disko in task 0002" / "arrive in later
tasks" framing; describe the filesystems and hardware profile as the
placeholder values they are.
- lib: drop the "no null-placeholder traversal hack" comparison to a prior
implementation.
- system: drop "no impure environment lookup" from the user.name description
and the sops/post-boot roadmap from the user comment.
26.05 is the latest stable NixOS release as of now (26.11 is still the
in-development branch that nixos-unstable reports); the previous 25.05 pin
was a release behind.
- flake.nix / flake.lock: stable overlay tracks nixos-26.05.
- neogaia system.stateVersion and the base home.stateVersion set to 26.05
(fresh install, so aligning to the current stable release).
- Refresh the "latest stable release" references in CONTEXT.md, the spec,
and the task file to match.
Other inputs are rolling branches (nixos-unstable, nixpkgs-unstable,
chaotic nyxpkgs-unstable) or master (home-manager, per spec), so they carry
no version to bump.
Stand up the walking skeleton the rest of the laptop MVI extends and
re-verifies against: the whole neogaia Host evaluates and its system
toplevel builds (nix flake check green).
- flake.nix: hand-rolled flake (no flake-parts). Base nixos-unstable, plus
nixpkgs-unstable and nixos-25.05 for the per-package unstable/stable
overlays, home-manager (nixpkgs followed), and chaotic-nyx (deliberately
not following our nixpkgs, to keep its binary cache usable). checks build
each Host toplevel.
- lib/: trimmed helper lib — the Auto-loader (recursive .nix discovery, no
null-placeholder hack), the host-builder, and the script-from-file helper.
Deps inherited explicitly; no with lib.my, no nixosModules output.
- system/: shared base config — the unstable/stable overlays, the user
option (defaults to alexion, in wheel, drives system + home-manager user
in lockstep), flakes, git, and home-manager as a NixOS module.
- modules/example.nix: Auto-loader / Enable-convention reference Module,
inert until enabled.
- hosts/neogaia/: minimal laptop Host — placeholder filesystems, bootloader,
and hardware profile, all superseded by disko in task 0002.
- CLAUDE.md: project agent instructions with a Gotchas section (nix on the
CachyOS dev host, the chaotic overlay/cache behaviour, tea/Gitea).
