`themes/engine/sddm.nix` defaulted `services.displayManager.autoLogin`
to `enable = true; user = "nomarchy";` (both mkDefault). The installer
flow overrode both with the real username at normal priority, so this
was invisible there — but a hand-migrated user (per docs/MIGRATION.md)
who imported `nomarchy.nixosModules.system` without setting
`autoLogin.user` would auto-login as a nonexistent "nomarchy" user and
SDDM would error. `docs/MIGRATION.md` even documented the override as a
post-import chore.
Flipped the default to `enable = lib.mkDefault false`. Installer
generates `enable = true` directly so its flow is unchanged. Migration
flow now gets the safe default — opt-in instead of opt-out — and the
docs row is updated to reflect the new shape.
The hardcoded "nomarchy" username fallback for `autoLogin.user` is the
same class of bug as the impermanence persistence block was. A future
roadmap row to consolidate "primary user" across impermanence,
autoLogin, and any future modules might be worthwhile, but it's
deferred — this commit is the immediate fix.
Found during Pillar 8 audit of first-boot UX.
`nomarchy-welcome` wrote a "starter" `~/.config/home-manager/home.nix`
for users without one. Two problems:
1. Wrong path. The installer-generated canonical home.nix lives at
`/etc/nixos/home.nix` and is imported via the flake (both
home-manager.users and the standalone homeConfigurations). Nothing
in the installer flow ever reads `~/.config/home-manager/home.nix`
— it's a dead file.
2. Broken content. The starter is missing `home.username`,
`home.homeDirectory`, `home.stateVersion`, and doesn't import
`nomarchy.nixosModules.home`. Even on a hand-migration path it
wouldn't evaluate as a standalone HM config.
So in the installer flow it's dead, and in the migration flow it's
broken. Removed Step 4 entirely. The git-init step (was Step 5) is
now Step 4. Hand-migrated users follow `docs/MIGRATION.md`, which has
the correct home.nix template.

Laptop, Desktop, Accessibility, and Gaming presets all shipped on
2026-04-26 but were still tagged (Next). Reorders the pillar so the
two genuinely open items (dGPU auto-detect, Surface support) lead.
Pillar 3 audited script existence; Pillar 8 audits feature behavior.
Adds a per-component sweep methodology (10 components, one PR each on
wave/qa-<component>) and lists it on the Now board so the next session
can pick it up without re-deriving scope.
Cleanup pass on Pillar 4: removes two "(Now)" entries (software-profile
multi-select, form-factor → laptop preset) already in the Shipped log,
and promotes the two remaining open items ("What's installed?" summary,
non-LUKS branch) to the Now board.
