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 the project docs 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.
- CLAUDE.md: project agent instructions with a Gotchas section (nix on the
CachyOS dev host, the chaotic overlay/cache behaviour, the forge CLI).
Capture the design work for the NixOS migration before any implementation:
- .claude/CONTEXT.md: domain glossary (Host, Module, Skeleton, Auto-loader,
Enable convention, unstable/stable overlay)
- .claude/adr/0001-sops-nix-for-secrets.md: secrets tooling decision
- .claude/spec/laptop-mvi.md: frozen minimum-viable-install spec for neogaia
- reference/: read-only snapshot of the current CachyOS configs (secrets and
state excluded), plus ENVIRONMENT.md profiling the live environment to guide
replication
Add a PreToolUse hook that reminds the main agent not to author test
files directly, and change the implement skill to always use
test-driven-development rather than only where possible.
implement: sync main and cut task-<NNNN>-<slug> before work, with
stop-and-ask guards for a dirty tree, a diverged main, and an unmerged
blocker. Replaces the no-commit rule with one commit, a push, and a PR
carrying the review's Risk block plus any unaddressed findings.
test-driven-development: every test is written by a general-purpose
sub-agent that never reads the implementation; the main agent writes the
code and never edits a test.
Wire Stop and Notification hooks in ~/.claude/settings.json to a new
~/.claude/hooks/attention-bell.sh, which rings the terminal bell in the
session pane so tmux monitor-bell flags the background window.
The hook runs detached (no controlling tty), so it walks its process
ancestry to the claude process and writes the BEL to that pane tty.
Also replaces the dead settings.json symlink (pointed at a now-missing
~/wrk/claude path) with a real tracked file.
The skill wasn't firing reliably, so instead of polluting the global
config with a skill that only helped *sometimes*, convert it into
project-specific instructions in .config/dot
Future work on this project (dotfiles) should always start from this
directory, even if changes are made outside. This helps Claude keep
the scope narrow.
dotcli is my utility script for everything dotfiles.
A bootstrap command is included in the README.
A test suite and the necessary scaffolding for extending
dotcli is also included.
