-## Architecture
-
-```
-profile (enable features)
-  → features (bundle applications/system + add packages)
-    → applications (system.nix + home.nix)
-    → system (NixOS config)
-```
-
-### Module Patterns
-
-**Simple Module** — Single file for NixOS-only or Home Manager-only configs:
-
-```nix
-{ lib, config, ... }:
-let cfg = config.my.system.audio;
-in {
-  options.my.system.audio.enable = lib.mkEnableOption "Audio";
-  config = lib.mkIf cfg.enable { ... };
-}
-```
-
-**Complex Module** — Directory with `default.nix`, `system.nix`, `home.nix`:
-
-```
-modules/applications/<app>/
-├── default.nix    # Master enable + imports
-├── system.nix     # NixOS config
-└── home.nix       # Home Manager config (sharedModules)
-```
-
-**Feature Module** — Bundles multiple applications/system modules:
-
-```nix
-{ lib, config, ... }:
-let cfg = config.my.features.gui.desktop;
-in {
-  options.my.features.gui.desktop.enable = lib.mkEnableOption "Desktop";
-  config = lib.mkIf cfg.enable {
-    my.applications = { niri.enable = true; gtk.enable = true; ... };
-  };
-}
-```
-
-**Profile** — Thin layer that only enables features:
-
-```nix
-{
-  my.features = {
-    gui.desktop.enable = true;
-    dev.agent.enable = true;
-  };
-}
-```

+# iOS Simulator 初期セットアップ
+
+この手順は `m2` の macOS 環境で、stable Xcode と最新の stable iOS Simulator Runtime を使える状態にするためのもの。
+
+## 前提
+
+- `m2` が `workload.development` profile を有効にしていること
+- Mac App Store に Apple Account でサインイン済みであること
+- dotfiles を最新化していること
+
+Xcode 本体は `applications.xcode` が Mac App Store 版を管理する。Simulator Runtime は Apple が管理する mutable state のため、Nix store には入れず専用 dev shell から導入する。
+
+## 1. macOS 設定を反映する
+
+リポジトリ直下で nix-darwin の設定を反映する。
+
+```bash
+sudo darwin-rebuild switch --flake .#m2
+```
+
+これにより `/Applications/Xcode.app` に stable Xcode がインストールされる。
+
+Xcode のインストールで Mac App Store の認証エラーになる場合は、App Store を一度開いてサインイン状態を確認してから再実行する。
+
+## 2. iOS Simulator Runtime を導入する
+
+初回セットアップは次の1コマンドで行う。
+
+```bash
+nix develop .#ios -c ios-simulator-install
+```
+
+`ios-simulator-install` は次を順に実行する。
+
+1. `/Applications/Xcode.app` が存在することを確認
+2. `xcode-select` の Developer Directory を stable Xcode に切り替え
+3. Xcode の first-launch components を導入
+4. 利用可能な新しい hardware support components を確認
+5. 選択中の Xcode に対応する最新の iOS Simulator Runtime をダウンロードしてインストール
+6. Xcode のバージョンとインストール済み Simulator Runtime を表示
+
+途中で `sudo` の認証を求められる場合がある。
+
+## 3. インストールを確認する
+
+```bash
+xcodebuild -version
+xcode-select -p
+xcrun simctl list runtimes
+xcrun simctl list devices available
+```
+
+`xcode-select -p` は次を指していること。
+
+```text
+/Applications/Xcode.app/Contents/Developer
+```
+
+`xcrun simctl list runtimes` に iOS runtime が表示されればセットアップ完了。
+
+## 4. Simulator を起動する
+
+```bash
+open -a Simulator
+```
+
+Simulator の Device メニューから、インストール済み runtime で利用可能な iPhone を選択する。
+
+## Runtime の更新
+
+Xcode を stable の新しいバージョンへ更新した後は、同じコマンドを再実行する。
+
+```bash
+nix develop .#ios -c ios-simulator-install
+```
+
+Xcode の選択、first-launch components、hardware support、iOS Simulator Runtime の状態をまとめて更新できる。
+
+## トラブルシューティング
+
+### Xcode が見つからない
+
+次のエラーが出る場合、先に nix-darwin の設定を反映する。
+
+```text
+Xcode is not installed at /Applications/Xcode.app.
+```
+
+```bash
+sudo darwin-rebuild switch --flake .#m2
+```
+
+### Simulator Runtime が見えない
+
+まず runtime 一覧を確認する。
+
+```bash
+xcrun simctl list runtimes
+```
+
+iOS runtime がない場合は再度インストーラーを実行する。
+
+```bash
+nix develop .#ios -c ios-simulator-install
+```
+
+### Command Line Tools 側を参照している
+
+```bash
+xcode-select -p
+```
+
+が `/Library/Developer/CommandLineTools` を指している場合でも、`ios-simulator-install` が `/Applications/Xcode.app/Contents/Developer` へ切り替える。
+
+手動で直す場合は次を実行する。
+
+```bash
+sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer
+```

+# nix-builder bootstrap
+
+The host configuration can be built before its cache signing secret exists.
+Harmonia's socket remains stopped until SOPS installs the signing key at
+`/run/secrets/harmonia/signing-key`.
+
+## Proxmox storage layout
+
+The host configuration expects three filesystems. Keep the build scratch space
+separate from the store so a large build cannot fill the root filesystem.
+
+| Mount point          | Suggested size | Contents                        |
+| -------------------- | -------------- | ------------------------------- |
+| `/`                  | 48 GiB         | NixOS and mutable system state  |
+| `/var/lib/nix-build` | 192 GiB        | Disposable build scratch space  |
+| `/nix/store`         | 1 TiB          | Fleet closures and binary cache |
+
+The build-server policy starts emergency store GC below 64 GiB free and aims
+for 128 GiB free. Persistent roots under `/var/lib/nix-fleet/roots` protect the
+latest fleet builds from that GC. It also limits Nix to two concurrent
+derivations while allowing each derivation to use every vCPU assigned to the
+VM.
+
+For the two dedicated ext4 data filesystems, remove the default root-reserved
+blocks once after formatting; keep the root filesystem's reserve intact:
+
+```bash
+sudo tune2fs -m 0 /dev/disk/by-label/nix-build
+sudo tune2fs -m 0 /dev/disk/by-label/nix-store
+```
+
+## Initial deployment
+
+Once the VM is reachable as `moons@nix-builder`, deploy it from the repository:
+
+```bash
+nix run .#deploy -- .#nix-builder
+```
+
+deploy-rs uses the target's `ssh-ng` store, so the system closure is built on
+the builder rather than copied from the laptop. Automatic and magic rollback
+remain enabled.
+
+## Add the host SOPS recipient
+
+After the VM has a stable SSH host key, derive its age recipient:
+
+```bash
+ssh-keyscan -t ed25519 nix-builder 2>/dev/null | ssh-to-age
+```
+
+Add the recipient to `.sops.yaml` and add a creation rule for
+`secrets/hosts/nix-builder/*.yaml`. The admin YubiKey recipient should remain in
+the same key group for recovery.
+
+## Generate the cache signing key
+
+Run this on a trusted Nix machine, preferably with the temporary files on a
+tmpfs:
+
+```bash
+nix-store --generate-binary-cache-key \
+  cache.app.homelabs.run-1 \
+  harmonia.private \
+  harmonia.public
+```
+
+Create `secrets/hosts/nix-builder/system.yaml` with SOPS and store the complete
+contents of `harmonia.private` at `harmonia.signing-key`:
+
+```yaml
+harmonia:
+  signing-key: cache.app.homelabs.run-1:REDACTED
+```
+
+Copy the complete contents of `harmonia.public` to
+`modules/systems/nix/homelab-cache/public-key`. The private plaintext file must
+not be committed or retained.
+
+After committing both encrypted/public files, select
+`networking.homelab-cache-client` on each client host.
+
+Redeploy the builder and verify the cache after installing the secret:
+
+```bash
+nix run .#deploy -- .#nix-builder
+curl --fail http://nix-builder:5000/nix-cache-info
+```
+
+## Normal operation
+
+Run `fleet-build` on the builder to build and root every NixOS host, or pass a
+list of host names to build only those hosts. Run `fleet-deploy` with the normal
+deploy-rs target syntax when additional fleet nodes have been added to
+`flake/deploy.nix`:
+
+```bash
+fleet-build
+fleet-build x1g13 galleria
+fleet-deploy .#nix-builder
+```
