 # Omarchy ISO
 
-The Omarchy ISO streamlines [the installation of Omarchy](https://learn.omacom.io/2/the-omarchy-manual/50/getting-started). It includes the Omarchy Configurator as a front-end to archinstall and automatically launches the [Omarchy Installer](https://github.com/basecamp/omarchy) after base arch has been setup.
+[![Nightly ISO Build](https://github.com/omacom/omarchy-iso/actions/workflows/nightly-build.yml/badge.svg?branch=quattro&event=schedule)](https://github.com/omacom/omarchy-iso/actions/workflows/nightly-build.yml?query=branch%3Aquattro+event%3Aschedule)
 
-## Downloading the latest ISO
+The Omarchy ISO is the only supported way to install Omarchy. It includes the Omarchy Configurator and installs Arch Linux and the Omarchy packages from the bundled mirror. It then runs target system setup in the chroot, creates the user, and runs `omarchy-provision-user` for that user.
 
-See the ISO link on [omarchy.org](https://omarchy.org).
+## Get Omarchy
+
+1. [Download the ISO](https://omarchy.org).
+2. Write it to a USB stick. Use [balenaEtcher](https://etcher.balena.io/) on Mac or Windows, or [caligula](https://github.com/ifd3f/caligula) on Linux.
+3. Turn off Secure Boot and/or TPM in the BIOS.
+4. Boot from the stick.
+5. Answer the configuration questions and select a drive.
+
+The install takes under a minute on the fastest machines and up to 5 minutes on an older computer.
+
+### Verify the download
+
+Verify the ISO before you write it to the stick. Otherwise, a corrupted download causes a pacman "invalid or corrupted package" error several minutes into the install.
+
+Every release ISO has a `.sha256` file and a `.sig` file next to it. Run these commands to download and verify the ISO of the latest release of [omacom/omarchy](https://github.com/omacom/omarchy/releases):
+
+```bash
+version=$(curl -fsSL https://api.github.com/repos/omacom/omarchy/releases/latest | jq -r .tag_name)
+version=${version#v}
+curl -fLO "https://iso.omarchy.org/omarchy-$version.iso"
+curl -fsSLO "https://iso.omarchy.org/omarchy-$version.iso.sha256"
+sha256sum -c "omarchy-$version.iso.sha256"
+```
+
+Use the `.sig` file to verify the ISO against the Omarchy signing key.
+
+### More in the manual
+
+- [Getting started](https://omarchy.org/manual/getting-started/): the install step by step, installing for another owner, and installing without encryption.
+- [Dual-boot install](https://omarchy.org/manual/dual-boot-install/): install Omarchy in the free space of a drive, beside Windows or another OS.
+- [Unattended installs](https://omarchy.org/manual/unattended-installs/): let the ISO install itself from a configuration on a second drive, with no keyboard and no wizard.
+
+# For maintainers
+
+The rest of this file covers building, testing and publishing the ISO.
+
+## What is published, and where
+
+| What | Where | When |
+| --- | --- | --- |
+| Release ISO | `https://iso.omarchy.org/omarchy-<version>.iso` | Each release |
+| Edge ISO | `https://nightly.omarchy.org/edge/<version>/omarchy-edge-<version>.iso` | Every night |
+| VM image of edge | `https://nightly.omarchy.org/edge/<version>/omarchy-edge-<version>.qcow2` | Every night |
+| VM image of the latest release | `https://nightly.omarchy.org/stable/<version>/<run>/omarchy-<version>.qcow2` | Once per release |
+| `latest.json` | `https://nightly.omarchy.org/edge/latest.json` and `.../stable/latest.json` | With each nightly build |
+
+Every ISO and every VM image has a `.sha256` file next to it. The release ISO also has a `.sig` file. Each VM image has an `unpacked/` folder next to it.
+
+On nightly.omarchy.org, a published file is never replaced. Only `latest.json` changes. It is written last, after every file of the version has been fetched back through the CDN and compared.
+
+## The nightly build
+
+`.github/workflows/nightly-build.yml` runs every night for two channels:
+
+- `edge`: builds the ISO from the edge channel: the edge packages and mirrors, and the edge builds of Omarchy (`omarchy-dev`).
+- `stable`: uses the latest release. The latest release of omacom/omarchy determines the version. The ISO comes from iso.omarchy.org and is used only if its signature matches the release key. A scheduled run skips a release that is already published. A manual run builds it again.
+
+Each ISO goes through the same install test that runs for pull requests: an unattended install, then a boot of the installed system. `test/vm-image/vm-seal` then turns the installed disk into a VM image, and `test/vm-image/vm-verify` boots that image and checks it. Nothing is published unless every check passes.
+
+A separate job publishes. It is the only job with the bucket's key, and it runs only on `quattro`. To try a change, run the workflow manually on a branch. That run builds and checks everything and publishes nothing.
+
+`test/vm-image/nightly-plan` decides which channels a run builds and where they are published. `test/vm-image/nightly-layout` lays out the files and writes `latest.json`. `test/unit/nightly-test.sh` tests both.
+
+## latest.json
+
+| Field | What it is |
+| --- | --- |
+| `version` | Edge: the build's date and run number, `2026.10.09.431`. Stable: the release, `4.0.4`. |
+| `channel` | `edge` or `stable`. |
+| `built_at` | When this file was written, after the image passed its checks. UTC, `2026-10-09T18:02:35Z`. |
+| `url` | The ISO that was installed. Edge: on nightly.omarchy.org. Stable: the release ISO on iso.omarchy.org. |
+| `sha256`, `size` | The ISO's SHA-256 and its size in bytes. |
+| `iso_commit` | The omarchy-iso commit the nightly build ran from. |
+| `omarchy_version` | The version of the Omarchy package in the image. |
+| `omarchy_commit` | Edge: the omarchy commit that package was built from. Stable: empty. |
+| `kernel` | The image's kernel release, as reported by `uname -r`. |
+| `vm.url`, `vm.sha256`, `vm.size` | The VM image: its URL, SHA-256 and size in bytes. |
+| `vm.unpacked` | The URL of the image's `unpacked/` folder, ending in `/`. |
+| `vm.unpacked_files` | Every file in that folder. |
+| `vm.user`, `vm.password` | The account for the desktop and `sudo`. |
+| `vm.ssh` | SSH authentication: keys only. Password authentication is off. |
+
+The version is also in the edge ISO's file name.
+
+## VM images
+
+VM images are for testing. Users download the release ISO from iso.omarchy.org.
+
+A VM image is Omarchy already installed, as one `.qcow2` file. There is an image of the edge channel, rebuilt every night, and an image of the latest release. Every boot is a new machine, with a new machine ID and new SSH host keys.
+
+The user is `omarchy` and the password is `omarchy`. SSH takes keys only.
+
+### Boot the image by itself
+
+The image boots through UEFI with no other file. Run these commands on a Linux machine with QEMU, read and write access to `/dev/kvm`, `curl` and `jq`:
+
+```bash
+latest=https://nightly.omarchy.org/edge/latest.json    # or .../stable/latest.json
+image=$(curl -fsSL "$latest" | jq -r .vm.url)
+curl -fLO "$image"
+curl -fsSLO "$image.sha256"
+sha256sum -c "${image##*/}.sha256"
+
+cp /usr/share/edk2/x64/OVMF_VARS.4m.fd vars.fd
+qemu-system-x86_64 -enable-kvm -cpu host -smp 4 -m 4G \
+  -drive if=pflash,format=raw,readonly=on,file=/usr/share/edk2/x64/OVMF_CODE.4m.fd \
+  -drive if=pflash,format=raw,file=vars.fd \
+  -drive file="${image##*/}",if=virtio,snapshot=on \
+  -device virtio-vga
+```
+
+The firmware paths are Arch's. `snapshot=on` keeps the downloaded image unchanged. The image is a 4 to 5 GB download.
+
+### Boot it faster, with SSH
+
+The `unpacked/` folder next to each image holds what a direct boot needs:
+
+| File | What it is |
+| --- | --- |
+| `vmlinuz`, `initrd`, `cmdline` | The image's own kernel, initramfs and kernel arguments. |
+| `vm-boot` | A script that boots the image directly into its kernel and gives it an SSH key. |
+| `SHA256SUMS` | Checksums of the files above. |
+
+A direct boot skips the firmware and the boot loader: SSH answers after about 6 seconds instead of about 20. Download the folder next to the image, then run `vm-boot`. It also needs `qemu-img` and `ssh`:
+
+```bash
+unpacked=$(curl -fsSL "$latest" | jq -r .vm.unpacked)
+for file in $(curl -fsSL "$latest" | jq -r '.vm.unpacked_files[]'); do curl -fsSLO "$unpacked$file"; done
+sha256sum -c SHA256SUMS
+chmod +x vm-boot
+
+./vm-boot "${image##*/}"             # boots, prints how to log in, runs until Ctrl-C
+./vm-boot "${image##*/}" uname -r    # boots, runs the command over SSH, powers off
+```
+
+`vm-boot` makes a new SSH key for each boot. It runs the machine on an overlay under `/var/tmp`, so the downloaded image is never changed, and deletes the overlay on exit. Set `VM_STATE_DIR` to put the overlay somewhere else.
+
+To get the URL of the edge ISO, run `jq -r .url` on the same `latest.json`.
+
+## Autoinstall
+
+The [manual's page](https://omarchy.org/manual/unattended-installs/) is the one for users; this is the same feature in full.
+
+The shipped ISO installs itself with no keyboard when it finds its configuration on a second drive. Attach a drive labeled `cidata` alongside the ISO and the installer copies the config off it and skips the configurator; with no such drive, nothing changes and the wizard runs as usual. No rebuild, no extra boot entry.
+
+`cidata` is the cloud-init `NoCloud` label, so Proxmox, libvirt, and Packer already know how to attach one.
+
+### Configuration files
+
+These are the configurator's own output files, so the way to get a starting set is to run one interactive install and copy what it wrote into `/root`.
+
+| File | Required | Purpose |
+|------|----------|---------|
+| `user_configuration.json` | Yes | archinstall config: disk, hostname, timezone, keyboard |
+| `user_credentials.json` | Yes | Username and password hash |
+| `user_full_name.txt` | No | Git full name |
+| `user_email_address.txt` | No | Git email |
+| `user_encrypt_installation.txt` | No | `true` when `user_configuration.json` carries a `disk_encryption` block; defaults to false |
+| `authorized_keys` | No | SSH public keys in sshd's own format, one per line |
+| `tailscale_authkey` | No | Tailscale auth key; the machine joins your tailnet on first boot |
+
+Both required files must be present or the installer falls back to the configurator. (A `defer-provisioning` marker file can stand in for `user_credentials.json`: user creation is then deferred to first boot.) Generate the password hash for `user_credentials.json` with `openssl passwd -6 "yourpassword"`.
+
+Encryption itself is configured by the `disk_encryption` block inside `user_configuration.json` — which carries the passphrase in plaintext, so treat a drive built from an encrypted install accordingly. The flag file must match it: it drives the encrypted install's SDDM autologin and the final boot validation, not the encryption.
+
+`authorized_keys` is the same file sshd reads — copy your own or write one key per line:
+
+```
+ssh-ed25519 AAAA... you@host
+```
+
+When `authorized_keys` is present, autoinstall installs it as the user's `~/.ssh/authorized_keys`, enables `sshd`, and adds a `ufw allow ssh` rule — a stock Omarchy install ships openssh with the service disabled and its firewall opens neither port 22 nor anything else beyond LocalSend and Docker's DNS. Networking needs nothing extra; NetworkManager is already enabled with DHCP. Password SSH authentication is left at the distro default. An `authorized_keys` with no keys in it fails the install rather than producing a machine nobody can reach.
+
+When `tailscale_authkey` is present (one key, blank lines and `#` comments ignored), the install adds the `tailscale` package from the ISO's bundled mirror — nothing is fetched from the network at install or boot — and stages the join for first boot: the key lands at `/etc/tailscale/authkey` (root-only), `tailscaled` is enabled, ufw allows traffic in on `tailscale0`, and a background unit runs `tailscale up` once the network is actually up, retrying until it succeeds without holding up the boot. After a successful join the key is deleted and the unit disables itself; until then both survive reboots, so a machine installed offline joins whenever it first gets connectivity. The node appears on the tailnet under the configured hostname. Use a reusable, pre-authorized (tagged) key so one drive image serves many machines — or an ephemeral key for disposable VMs.
+
+The region follows `timezone`, exactly as in an interactive install: a timezone listed in one of the runtime's region profiles (`default/regions/*/timezones`, such as `Asia/Shanghai` for `cn`) selects that profile's mirrors and repositories, and anything else is global. Set `omarchy_install.region` in `user_configuration.json` to pick one explicitly, for example `"cn"` on a deferred-provisioning install, which carries `UTC` until first boot. Every ISO bundles every profile's packages, so a regional install still needs no network.
+
+### Building the drive
+
+```bash
+mkdir cidata
+cp user_configuration.json user_credentials.json authorized_keys cidata/
+genisoimage -output cidata.iso -volid cidata -joliet -rock cidata/
+```
+
+### Proxmox example
+
+```bash
+qm create 101 --name my-omarchy \
+  --bios ovmf --machine q35 --cpu host --cores 4 --memory 8192 \
+  --ostype l26 --scsihw virtio-scsi-single \
+  --efidisk0 local-lvm:0,efitype=4m,pre-enrolled-keys=0 \
+  --scsi0 local-lvm:40,discard=on,iothread=1 \
+  --net0 virtio,bridge=vmbr0 --vga virtio --serial0 socket \
+  --ide2 local:iso/omarchy.iso,media=cdrom \
+  --ide3 local:iso/cidata.iso,media=cdrom \
+  --boot order='scsi0;ide2'
+
+qm start 101
+```
+
+Boot order is disk first: the empty disk falls through to the ISO on the first boot, and the installed system boots from disk afterwards. The machine reboots into Omarchy on its own when the install finishes.
+
+Encrypted autoinstalls are not fully unattended — the LUKS passphrase prompt still needs someone at the first boot.
 
 ## Creating the ISO
 
-Run `./bin/omarchy-iso-make` and the output goes into `./release`. You can build from your local $OMARCHY_PATH for testing by using `--local-source` or from a checkout of the dev branch (instead of master) by using `--dev`.
+Run `./bin/omarchy-iso-make`; output goes into `./release`. By default the ISO uses the Omarchy packages and tracks the `quattro` branch, from the stable mirror. Pass `--edge` to use `omarchy-dev` and `omarchy-settings-dev` from the edge mirror.
 
-### Environment Variables
+For local development, build the ISO from sibling checkouts:
 
-You can customize the repositories used during the build process by passing in variables:
-
-- `OMARCHY_INSTALLER_REPO` - GitHub repository for the installer (default: `basecamp/omarchy`)
-- `OMARCHY_INSTALLER_REF` - Git ref (branch/tag) for the installer (default: `master`)
-
-Example usage:
 ```bash
-OMARCHY_INSTALLER_REPO="myuser/omarchy-fork" OMARCHY_INSTALLER_REF="some-feature" ./bin/omarchy-iso-make
+./bin/omarchy-iso-make --local-source ../omarchy-installer ../omarchy-pkgs
 ```
 
+Despite the local folder name, the first argument is the Omarchy source checkout (runtime commands, configs, setup scripts, themes, shell, migrations). The installer itself lives in this ISO repo.
+
+The configurator asks for the language on its first screen: English or Simplified Chinese. Chinese reruns the installer in cage + foot, a console that draws Chinese, with Noto Sans Mono CJK unpacked from the offline mirror's `noto-fonts-cjk`. It opens on the keyboard screen, offers only keyboards with a US keymap (cage keeps a US layout) and preselects Chinese (Simplified, Pinyin); every later screen and the install progress read in Chinese. Esc there goes back to a bilingual language screen, where English returns to the VT, which applies the chosen keymap. Without a working display or the font, Chinese continues in English on the VT. Either way a Chinese install sets the target's `LANG` to `zh_CN.UTF-8` through archinstall's `locale_config`. The language never decides the region: that follows the timezone. The Chinese text lives in `OMARCHY_ZH` tables beside the English it replaces.
+
+Use `--dev` or `--rc` to build against those package channels. Both `--dev` and `--edge` select the dev packages from the edge mirror.
+
 ## Testing the ISO
 
 Run `./bin/omarchy-iso-boot [release/omarchy.iso]`.
 
+Run `./test/all` for the fast, VM-free tests under `test/unit/`, which cover cidata autoinstall loading and the orchestrator's phases without needing a built ISO.
+
+To exercise installation alongside existing Windows-style partitions, run
+`./bin/omarchy-iso-test-windows-disk [release/omarchy.iso]`. It creates a
+synthetic disk in `/tmp` with an existing ESP and data partition plus ample
+unallocated space, then offers to start an interactive installation on it. The
+fixture exercises Windows partition preservation but does not contain Windows.
+
+## Acceptance testing the ISO
+
+Run `./bin/omarchy-iso-test [release/omarchy.iso]` to install the ISO into a headless VM by driving the real interactive install flow — the harness reads each screen via QMP screendumps + OCR and answers with virtual keystrokes, so the configurator wizard, install dashboard, reboot prompt, and SDDM login are all exercised exactly as a user would. It then boots the installed system, sends real VM keyboard shortcuts for the primary shell and window-management actions, and runs the in-guest acceptance suite (`test/acceptance` in the omarchy repo). The suite checks session and service health, the complete core-package manifest, user defaults, representative applications, menus, panels, live weather, launchers, visual selectors, notifications, clipboard, and other interactive shell behavior.
+
+Visual checkpoints are saved as `success-<step>.png` or `failure-<step>.png` alongside the serial and install logs in `test-runs/<iso>/runs/<timestamp>/`. Independent test files and applications continue after a failure so one broken surface does not hide the rest of the report. The harness then stops the VM and opens the ordered screenshots in `imv` for quick visual review.
+
+The harness syncs the acceptance suite from `$OMARCHY_PATH` when it is available. The install phase produces a reusable base image, so iterating against another checkout is fast:
+
+```bash
+./bin/omarchy-iso-test release/omarchy.iso --install-only        # once per ISO
+./bin/omarchy-iso-test release/omarchy.iso --reuse-base \
+  --sync-omarchy ../omarchy                                      # fast loop against local tests
+```
+
+Pass `--encrypt` to drive the encrypted install flow (including typing the LUKS passphrase at boot) instead of the unencrypted one. Pass `--no-preview` to collect the same visual artifacts without opening them in `imv` when the run finishes.
+
+## Integration testing the ISO
+
+Scenarios under `test/integration.d/` boot a real ISO install in QEMU and assert on what the running system actually does. The runner installs the ISO once — unattended, from a generated cidata drive — and saves the result as a reusable base image; every scenario then boots a throwaway overlay of that base with its own copy of the firmware vars, so neither disk nor NVRAM state leaks between runs. Shared machinery (VM lifecycle, QMP screendump + OCR console driving, virtual keystrokes, guest SSH, the cidata build) lives in `test/integration.d/base-test.sh`, so a new scenario is one file.
+
+```bash
+./test/integration release/omarchy.iso                   # install once, run all scenarios
+./test/integration release/omarchy.iso --reuse-base      # fast loop against the saved base
+./test/integration release/omarchy.iso factory-reset     # a single named scenario
+```
+
+The first scenario is `factory-reset`: it proves `omarchy-system-factory-reset` hands a machine on without destroying a shared ESP. The installed ESP gets a Windows entry with payload plus a second Linux cloned under a foreign machine-id with its own boot directory and UKIs; a real factory reset is then driven through a guest pty, and the harness asserts the foreign entries survive both the staged reset and first-boot provisioning, that the old Omarchy identity is fully retired, and that the machine reaches first-boot setup unattended.
+
+Artifacts — screenshots, the fixtured/staged/final `limine.conf`, the reset typescript, and the factory-reset log — land under `test-runs/<iso>-integration/runs/<timestamp>-<scenario>/`, and `--no-preview` skips the `imv` review just like the acceptance harness.
+
+## Upgrade testing
+
+`test/upgrade-test` checks what an existing user gets. It takes an installed system, moves it to another channel with `omarchy-channel-set`, reboots it, and checks what came back: the update's exit status, skipped migrations, that the reboot comes back by itself into an installed kernel, failed units, the desktop, the user's wallpaper and the boot menu.
+
+```bash
+./test/integration release/omarchy.iso boot                                # installs once, leaves the installed disk
+./test/upgrade-test test-runs/omarchy-integration edge upgrade-evidence    # edge or rc
+```
+
+The evidence folder gets `report.md`, the update's output, and a picture of the desktop before and after.
+
+The "Upgrade test" workflow does both steps from a release's ISO. Start it by hand, from the latest release to edge by default:
+
+```bash
+gh workflow run upgrade-test.yml -f to=edge
+```
+
+It only runs when started. When the branch it ran on has a pull request, the result is posted there as one comment and updated in place on later runs.
+
 ## Signing the ISO
 
-Run `./bin/omarchy-iso-sign [gpg-user] [release/omarchy.iso]`.
+Run `./bin/omarchy-iso-sign [release/omarchy.iso]`. The signing key is retrieved from the shared Omarchy vault with the 1Password CLI.
 
 ## Uploading the ISO
 
-Run `./bin/omarchy-iso-upload [release/omarchy.iso]`. This requires you've configured rclone (use `rclone config`).
+Run `./bin/omarchy-iso-upload [release/omarchy.iso]`. This requires rclone configuration (`rclone config`). The `.sig` and `.sha256` sidecars go up with the ISO when they exist beside it.
 
 ## Full release of the ISO
 
-Run `./bin/omarchy-iso-release` to create, test, sign, and upload the ISO in one flow.
+Run `./bin/omarchy-iso-release VERSION` to create, test, sign, and upload the ISO in one flow. Add `--rc` to release an RC build instead.

+Usage: omarchy-iso-test-windows-disk [--recreate] [--gap] [release/omarchy.iso]
+
+Creates or validates a synthetic Windows-style test disk with:
+  - a 512MiB EFI partition containing EFI/Microsoft
+  - an existing ext4 data partition with a preservation marker
+  - more than 64GiB of contiguous unallocated space for Omarchy
+
+This exercises Windows partition detection and preservation; it is not a
+bootable Windows installation.
+
+--gap builds the same fixture with a hole in the partition numbering: a third
+partition is created and then deleted, leaving slot 3 free while slot 4 stays
+in use. parted fills the lowest free slot, so the installer must create its
+partitions as 3 and 5 and read those numbers back. The contiguous fixture
+cannot catch that class of bug, because there "lowest free" and "highest + 1"
+are the same number.
+
+Options:
+  --recreate  Replace the existing test fixture
+  --gap       Build the numbering-hole variant (separate disk image)
+  -h, --help  Show this help

+# Plan: aarch64 (Generic UEFI ARM64) build for omarchy-iso
+
+## Context
+
+omarchy-iso currently produces a single x86_64 Arch Linux live ISO. The build is x86-baked from top to bottom — profile arch, package list filename, microcode, kernel choice (`linux-t2`), bootloader configs (BIOS syslinux + UEFI GRUB), squashfs BCJ filter, Node.js download URL, QEMU smoke-test, release filename, and CI runner.
+
+Target: a parallel **generic UEFI aarch64** ISO — boots on Ampere servers, AWS Graviton VMs, Snapdragon X laptops, ARM dev kits. Anything that exposes vanilla UEFI + ACPI. Apple Silicon (Asahi) and SBCs (U-Boot/rpi-firmware) are out of scope.
+
+**Assumption:** cross-repo dependencies are someone else's problem to land first. This plan only covers omarchy-iso. The hard prerequisites are listed up front so it's clear what blocks the first green build.
+
+---
+
+## Hard prerequisites (NOT in this plan, but block any green build)
+
+These exist outside omarchy-iso. Flagged for visibility — without them, nothing here boots:
+
+1. **aarch64 base packages must exist somewhere we can pacman from.** Vanilla Arch (`geo.mirror.pkgbuild.com`) is x86_64-only — there is no `core/os/aarch64`. The realistic source is **Arch Linux ARM** (`mirror.archlinuxarm.org`) for `core`/`extra`/`alarm`/`aur`. Decision required: target Arch Linux ARM as the aarch64 base distribution.
+2. **`pkgs.omarchy.org/{stable,edge}/aarch64/`** must serve a real repo. Probed today, both return 404. omarchy-pkgs already has multi-arch build support per its README, so this is a publish step, not a port.
+3. **Omarchy ISO architecture guard** must allow supported architectures or scope any x86_64-only checks behind an explicit guard.
+4. **archinstall + Limine** must work end-to-end on aarch64. archinstall supports it; Limine supports aarch64 UEFI. Worth a manual verification before committing to this bootloader path on ARM.
+
+---
+
+## Approach
+
+Add an `--arch aarch64` flag to `bin/omarchy-iso-make`. Branch on it everywhere x86_64 is currently assumed. Don't fork the profile directory — overlay arch-specific files at build time so the two architectures share one source of truth.
+
+Output artifact naming already uses no arch suffix until release-time renaming, so two parallel builds coexist cleanly.
+
+---
+
+## Concrete changes
+
+### 1. Build entrypoint — `bin/omarchy-iso-make`
+
+- Add `--arch x86_64|aarch64` flag (default `x86_64` for backward compat).
+- Pass `OMARCHY_ARCH` env var into the container.
+- Switch the docker image / platform per arch:
+  - x86_64: `archlinux/archlinux:latest` (unchanged)
+  - aarch64: `archlinuxarm/archlinuxarm:latest` (or `menci/archlinuxarm` — pick whichever publishes a recent multi-arch image), with `--platform linux/arm64`. Native arm64 host preferred; QEMU emulation works but is slow.
+- Don't change pacman cache mount on the host: pacman keeps per-arch subdirs, so the cache is safe to share.
+
+### 2. Profile — `configs/profiledef.sh`
+
+Change `arch` and the squashfs BCJ filter at runtime. Either:
+- Keep one `profiledef.sh` and have `builder/build-iso.sh` `sed` the arch line + BCJ filter (`x86` → `arm`) before `mkarchiso` runs, **or**
+- Source `OMARCHY_ARCH` directly inside `profiledef.sh` (mkarchiso sources this file with bash, so env access is fine).
+
+`bootmodes` also needs to drop `bios.syslinux` for aarch64 (BIOS boot is x86-only) — `bootmodes=('uefi.grub')` on ARM.
+
+### 3. Build script — `builder/build-iso.sh`
+
+- **Line 56–57**: Node.js URL grep. Branch on `OMARCHY_ARCH`:
+  - `x86_64` → `linux-x64.tar.gz`
+  - `aarch64` → `linux-arm64.tar.gz`
+- **Line 73**: package additions. Drop `linux-t2` for aarch64 (T2-only x86 kernel) — use plain `linux`. Write to `packages.${OMARCHY_ARCH}` instead of hardcoded `packages.x86_64`.
+- **Line 77**: read same `packages.${OMARCHY_ARCH}` for offline mirror enumeration.
+- **archiso releng overlay** (`cp -r /archiso/configs/releng/*`): the upstream `releng` profile ships only `packages.x86_64`. For aarch64, copy `packages.x86_64` to `packages.aarch64` and prune obviously x86-only entries (`memtest86+`, `intel-ucode`, `amd-ucode`, `edk2-shell` x64 binary, `syslinux`). Land this as a small fixup step in `build-iso.sh` rather than a full fork of `releng`.
+
+### 4. archinstall package list — `builder/archinstall.packages`
+
+Drop microcode for aarch64 — `intel-ucode` and `amd-ucode` don't exist for ARM. Either:
+- Two lists (`archinstall.packages.x86_64`, `archinstall.packages.aarch64`), or
+- One list with sentinel comments and a filter step in `build-iso.sh:80` that drops microcode lines when `OMARCHY_ARCH=aarch64`.
+
+The second is less duplication for one-line drift.
+
+### 5. Bootloader configs
+
+aarch64 has no BIOS — only UEFI. Drop the syslinux path entirely on ARM.
+
+- **Skip on aarch64**: `configs/syslinux/*` (BIOS syslinux), `configs/grub/*` references to `shellx64.efi`/`shellia32.efi` (lines 81–85 of `grub.cfg`).
+- **`configs/efiboot/loader/loader.conf`**: change `default 01-archiso-x86_64-linux.conf` to a per-arch entry. Either two loader.conf files (selected by build-iso.sh) or rename the entry generically (`01-archiso-linux.conf`) and keep one file.
+- **`configs/efiboot/loader/entries/01-archiso-x86_64-linux.conf`**: produce an aarch64 sibling (`01-archiso-aarch64-linux.conf`) at build time — same template, drop microcode initrd lines, swap title. The kernel/initrd paths use `%ARCH%` already in `grub.cfg` but are hardcoded `x86_64` in this file (line 3–4).
+- **`configs/grub/grub.cfg` and `loopback.cfg`**: remove or guard the x86_64 conditionals. The `%ARCH%` placeholder gets substituted by mkarchiso from `profiledef.sh:arch`, so the kernel/initrd paths flip automatically. Manually-written `grub_cpu == 'x86_64'` blocks (lines 34–39, 68, 81–85) should drop on aarch64 builds — easiest done with a build-time sed for the aarch64 path, or by extracting them into a separate `grub-x86_64.cfg.fragment` only included on x86 builds.
+
+The cleanest cut: keep one `grub.cfg` shared, strip the x86 shell/memtest fragments at build time when `OMARCHY_ARCH=aarch64`. Don't fork the file.
+
+### 6. mkinitcpio preset — `configs/airootfs/etc/mkinitcpio.d/linux-t2.preset`
+
+Names `vmlinuz-linux-t2` and `initramfs-linux-t2.img`. The filename is the pkgbase and the alpm hook keys off it, so aarch64 does not rename this file — it simply does not ship it, and releng's own `linux.preset` covers the stock kernel. Drop `linux-t2` from `arch_packages` on aarch64 and the boot entries point at `vmlinuz-linux` / `initramfs-linux.img`.
+
+### 7. Configurator — `configs/airootfs/root/configurator`
+
+Lines 320–325:
+```bash
+if lspci -nn 2>/dev/null | grep -q "106b:180[12]"; then
+  kernel_choice="linux-t2"
+else
+  kernel_choice="linux"
+fi
+```
+T2 detection is harmless on aarch64 (`lspci` returns no match), so `kernel_choice` falls through to `linux`. **No change strictly required**, but clearer to wrap the lspci probe in `[[ $(uname -m) == "x86_64" ]]` so the intent reads correctly. Cheap.
+
+The archinstall JSON's `mirror_config.custom_servers` (lines 422–424) points at `mirror.omarchy.org`, `mirror.rackspace.com/archlinux`, `geo.mirror.pkgbuild.com` — none of these serve aarch64. For aarch64 the list must be `mirror.archlinuxarm.org` and friends. Branch the JSON template on `OMARCHY_ARCH` (or `uname -m` at runtime, since this file runs on the live ISO).
+
+### 8. pacman configs — `configs/pacman-online-{stable,rc,edge,offline}.conf`
+
+The `$arch` placeholder is pacman-resolved (matches `Architecture = auto`), so `https://stable-mirror.omarchy.org/$repo/os/$arch` adapts automatically — **as long as the mirror serves aarch64**. The omarchy mirror is the bottleneck (prerequisite #2). The `arch-mact2` repo is x86-only by definition; gate it behind arch on aarch64 builds (drop the section).
+
+### 9. Smoke-test scripts — `bin/omarchy-iso-boot`, `bin/omarchy-vm`
+
+Detect arch from the ISO filename (or accept a flag) and switch:
+- x86_64: `qemu-system-x86_64`, `/usr/share/edk2/x64/OVMF_CODE.4m.fd` + `OVMF_VARS.4m.fd` (unchanged).
+- aarch64: `qemu-system-aarch64`, `-machine virt -cpu max`, `/usr/share/edk2/aarch64/QEMU_CODE.fd` + `QEMU_VARS.fd` (Arch package: `edk2-armvirt`).
+
+Both scripts hardcode the OVMF path; small, mechanical fix.
+
+### 10. Release script — `bin/omarchy-iso-release:52`
+
+```bash
+latest_iso=$(\ls -t "$BUILD_RELEASE_PATH"/*${OMARCHY_ARCH}-"$ISO_REF".iso | head -n1)
+```
+Hardcoded `x86_64` glob. Take an arch arg, or do `*${OMARCHY_ARCH}-${ISO_REF}.iso`. The ISO filename already contains arch (set by archiso from `profiledef.sh`), so this just needs the glob parameterized.
+
+### 11. CI — `.github/workflows/nightly-build.yml`
+
+Add a matrix:
+```yaml
+strategy:
+  matrix:
+    arch: [x86_64, aarch64]
+    include:
+      - arch: x86_64
+        runner: ubuntu-latest
+      - arch: aarch64
+        runner: ubuntu-24.04-arm   # GitHub-hosted ARM runner, GA
+```
+Pass `--arch ${{ matrix.arch }}` to the build. Upload artifacts named per-arch.
+
+If GitHub-hosted ARM runners aren't available on this org's plan, fall back to QEMU emulation on `ubuntu-latest` (slow, ~3-4× build time) or self-hosted.
+
+---
+
+## Files to modify (summary)
+
+Code:
+- `bin/omarchy-iso-make` — add `--arch` flag, branch docker image/platform
+- `bin/omarchy-iso-boot` — branch QEMU binary + OVMF path
+- `bin/omarchy-vm` — same as iso-boot
+- `bin/omarchy-iso-release` — parameterize ISO glob
+- `builder/build-iso.sh` — main branching: Node.js URL, package list filename, releng overlay fixups, kernel package
+- `builder/archinstall.packages` — filter microcode on aarch64 (sentinel comments + filter step)
+- `configs/profiledef.sh` — env-driven `arch` + BCJ filter + bootmodes
+- `configs/efiboot/loader/loader.conf` — per-arch default entry
+- `configs/efiboot/loader/entries/01-archiso-x86_64-linux.conf` — generate aarch64 sibling at build time
+- `configs/grub/grub.cfg`, `loopback.cfg` — strip x86-only fragments on aarch64
+- `configs/airootfs/etc/mkinitcpio.d/linux-t2.preset` — omit on aarch64 (drop linux-t2 there; releng's linux.preset covers the stock kernel)
+- `configs/airootfs/root/configurator` — branch archinstall JSON mirror list on `uname -m`; optionally guard lspci T2 probe
+- `.github/workflows/nightly-build.yml` — matrix x86_64/aarch64
+
+No new files unless we go the dual-list route on archinstall.packages or efiboot loader entries; preferred path is build-time templating to keep one source of truth.
+
+---
+
+## Verification
+
+**Local (host is x86_64):**
+1. `bin/omarchy-iso-make --arch x86_64` — must produce a byte-similar ISO to today's nightly (smoke test for regressions in the refactor).
+2. `bin/omarchy-iso-make --arch aarch64` — succeeds (slow under QEMU binfmt; expect 30-60 min).
+3. `bin/omarchy-iso-boot release/omarchy-*-aarch64-*.iso` — boots to the configurator under `qemu-system-aarch64 -machine virt`. Walk through the picker, confirm archinstall lays down a working system, reboot into the installed system.
+4. Live-iso shell: `pacman -Sy && pacman -Si linux` returns an aarch64 package from `mirror.archlinuxarm.org`.
+
+**On real hardware (post green QEMU run):**
+- AWS Graviton VM (`c7g.medium`, dd ISO to a volume, attach as boot) — fastest cloud check, no hardware needed.
+- One physical ARM64 UEFI box if available (Ampere dev kit, Snapdragon X laptop, etc.) — the long pole.
+
+**CI:**
+- Both matrix legs go green on a manual `workflow_dispatch` before merging.
+- Nightly produces both ISOs as artifacts.
+
+---
+
+## Open risks (call out before implementation)
+
+1. **mkarchiso on aarch64 is less-trodden ground.** It accepts `arch="aarch64"`, but the upstream Arch project doesn't dogfood it. Expect to file/patch around small bugs in archiso's helper scripts. Keep the archiso submodule pin tight so a regression doesn't surprise nightly.
+2. **Limine + LUKS + Btrfs + Snapper on aarch64** — every one of these works individually on ARM, but the combination is what omarchy ships. Worth one manual end-to-end pass before declaring done.
+3. **Apple T2 / linux-t2 / `arch-mact2` repo** are silently dropped on aarch64; users mistakenly trying to install the aarch64 ISO on a T2 Mac will get an obviously-wrong result. The configurator could refuse to install when arch mismatch is detected, but that's outside this plan.

+# Consumer Secure Boot Plan: Microsoft Shim + MOK + UKI
+
+## Goal
+
+Support Omarchy installs on consumer laptops that ship with UEFI Secure Boot enabled and trust the Microsoft UEFI CA, without requiring users to disable Secure Boot.
+
+This plan targets normal consumer hardware, especially Windows dual-boot machines. OEM-controlled hardware with Omarchy-owned firmware keys is a separate path.
+
+## Current State (August 2026)
+
+Where the repo stands today, and what that changes about this plan:
+
+- The ISO builds with `bootmodes=('bios.syslinux' 'uefi.grub')` (`configs/profiledef.sh`): an unsigned GRUB as `BOOTX64.EFI` loading an unsigned kernel and initramfs. Firmware that trusts only the Microsoft UEFI CA rejects the ISO at the first stage, so Secure Boot must be disabled today.
+- The vendored mkarchiso already supports a `uefi.systemd-boot` bootmode (mutually exclusive with `uefi.grub`), so the live-ISO half of `shim -> systemd-boot -> UKI` needs no archiso surgery — a bootmode switch plus signing.
+- The installed system already boots a UKI: the orchestrator's `finalize_limine_boot` phase has mkinitcpio build the UKI onto the ESP, and `validate_boot` asserts it exists. "Build an installed UKI" is no longer new work; the new work is signing that UKI and choosing a second stage that enforces signatures.
+- Kernel updates already regenerate the UKI through the target's mkinitcpio pacman hooks. The update flow below reduces to adding a signing step and fallback retention to machinery that exists.
+
+The critical path is external: the Microsoft-signed shim. That requires an EV code-signing certificate for the Omarchy org, a shim built from a reviewed upstream release with Omarchy SBAT identity and NX compatibility, and a `shim-review` submission — historically weeks to months of calendar time, with standing obligations afterward (SBAT revocation response, resubmission when the embedded cert or shim version changes). Start it first; every phase below except release signing can proceed in parallel on dev test keys in QEMU.
+
+## Core Architecture
+
+Use a Microsoft-signed first-stage shim, then boot only signed Omarchy-controlled artifacts.
+
+```text
+Firmware Secure Boot
+  -> Microsoft-signed Omarchy shim
+    -> MokManager when key enrollment is pending
+    -> signed second-stage boot manager
+      -> signed Unified Kernel Image (UKI)
+        -> encrypted Omarchy root
+```
+
+For the installed OS, use machine-local Machine Owner Key (MOK) signing for UKIs generated during install and later kernel updates.
+
+## Why MOK For Installed Systems
+
+Omarchy's installed UKI is machine-specific because it includes or depends on install-time data such as:
+
+- Kernel command line for encrypted root.
+- Initramfs generated for the installed system.
+- Kernel package version selected at install or update time.
+
+We must not ship Omarchy's private release signing key on the ISO or installed system. Therefore:
+
+1. The official ISO is signed by Omarchy release infrastructure.
+2. During install, generate a machine-local Secure Boot keypair.
+3. Enroll the public certificate through MokManager.
+4. Sign installed UKIs and update-generated UKIs with the local private key.
+5. Store the local private key only on the encrypted installed root, never on the ESP.
+
+This preserves offline tamper resistance for `/boot` while avoiding any central private key on user machines.
+
+## Scope Constraints
+
+- UEFI only.
+- Microsoft UEFI CA trust path only for consumer machines.
+- No custom firmware key enrollment for v1 consumer installs.
+- No TPM auto-unlock for Omarchy root in v1.
+- No attempt to modify Windows BitLocker protectors or TPM ownership.
+- Secure Boot mode uses signed UKIs only; no unsigned external kernel, initramfs, or command line files.
+- Secure Boot mode may use a different boot manager than the current Limine path until Limine has a proven verified-boot story.
+
+## Bootloader Decision
+
+Installed systems already boot a UKI through Limine, so the boot *artifact* needs no change. But signing Limine as an EFI binary is not sufficient if Limine will then load unsigned payloads or take direction from an unsigned `limine.conf`. For v1 Secure Boot support, use a boot path with a small, enforceable verification surface:
+
+```text
+shim -> systemd-boot -> signed UKI
+```
+
+Policy:
+
+- Keep Limine as the normal non-Secure-Boot bootloader unless we later prove Limine enforces signed payloads correctly.
+- Use systemd-boot only for Secure Boot installs if that is the fastest reliable path.
+- Boot only UKIs with embedded command line and initramfs.
+- Disable or avoid unsigned boot entry editing in Secure Boot mode.
+
+If later validation proves Limine can enforce signed payloads behind shim, this plan can swap the second stage while keeping the shim, MOK, UKI, and signing architecture.
+
+## Required Artifacts
+
+### Omarchy Shim Artifacts
+
+These are release artifacts, not generated on normal developer machines:
+
+- `shimx64.efi`, signed by Microsoft UEFI CA.
+- `mmx64.efi` / MokManager artifact compatible with the shim.
+- Optional `fbx64.efi` fallback artifact if needed by the selected shim packaging.
+- Shim SBAT metadata owned by Omarchy.
+- Omarchy public release certificate embedded in shim.
+
+Do not depend on another distribution's shim as a permanent product strategy. Omarchy needs its own shim submission, SBAT identity, revocation path, and release process.
+
+### Omarchy Signing Material
+
+Release infrastructure owns:
+
+- Omarchy Secure Boot release private key, stored offline or in an HSM-backed CI secret store.
+- Omarchy Secure Boot release public certificate, embedded in shim and shipped for verification.
+
+Installed systems own:
+
+- Machine-local MOK private key, stored on encrypted root with `0600` permissions.
+- Machine-local MOK public certificate, enrolled through MokManager.
+
+Private keys must never be committed to this repo.
+
+## Build-Time Flow
+
+Add a Secure Boot-capable ISO build mode.
+
+```text
+bin/omarchy-iso-make --secure-boot
+```
+
+Build behavior:
+
+1. Switch the UEFI bootmode from `uefi.grub` to `uefi.systemd-boot` in `configs/profiledef.sh` (mkarchiso forbids running both). BIOS syslinux stays as-is; Secure Boot is UEFI-only.
+2. Add Microsoft-signed Omarchy shim artifacts to the ISO UEFI boot path.
+3. Build the live environment boot payload as a UKI.
+4. Sign the live UKI with the Omarchy release key in official builds.
+5. Sign any second-stage EFI binary with the Omarchy release key.
+6. Assert that every Secure Boot UEFI entry uses the signed shim path.
+7. Assert that no unsigned kernel/initramfs path is offered in Secure Boot UEFI mode.
+
+Local developer builds should support a dev-signing mode for QEMU validation:
+
+```text
+OMARCHY_SECURE_BOOT_SIGNING_MODE=dev
+```
+
+Dev mode creates local test keys and is only expected to boot in QEMU firmware enrolled with those test keys. It must not be presented as Microsoft Secure Boot compatible.
+
+## Installed-System Flow
+
+When the live installer detects Secure Boot enabled:
+
+1. Show a Secure Boot explanation before disk mutation.
+2. If Windows is detected, follow the shipped dual-boot BitLocker policy (decrypt, not suspend — see the configurator's existing checks) and warn the user to have the recovery key available.
+3. Install Omarchy's shim to its own ESP directory, for example `EFI/Omarchy`.
+4. Do not modify `EFI/Microsoft`.
+5. Generate a machine-local MOK keypair under the installed encrypted root.
+6. Build an installed UKI with embedded kernel, initramfs, command line, and OS release data.
+7. Sign the installed UKI with the machine-local MOK private key.
+8. Sign the selected second-stage boot manager with the machine-local MOK private key, unless it is release-signed and expected to remain static.
+9. Schedule public certificate enrollment with `mokutil --import`.
+10. Tell the user they must complete MokManager enrollment on the next reboot.
+11. Preserve current firmware boot order by default on dual-boot machines.
+
+Expected first reboot sequence after install:
+
+```text
+Firmware -> Omarchy shim -> MokManager -> user enrolls Omarchy machine key -> reboot -> Omarchy shim -> signed boot manager -> signed UKI -> LUKS unlock
+```
+
+## Kernel Update Flow
+
+Secure Boot installs need deterministic UKI regeneration and signing after kernel or initramfs changes.
+
+The regeneration half already exists: the target's mkinitcpio pacman hooks rebuild the UKI on kernel or initramfs changes. Add the signing half — a hook ordered after the UKI build that:
+
+1. Signs the freshly built UKI with the machine-local MOK private key.
+2. Writes it atomically to the ESP.
+3. Keeps at least one previously booted signed UKI as fallback.
+
+Failure policy:
+
+- If signing fails, do not replace the currently bootable UKI.
+- If ESP space is low, keep the current UKI and fail loudly.
+- If the local signing key is missing, block the update from producing an unsigned boot artifact.
+
+## File Changes
+
+### `bin/omarchy-iso-make`
+
+Add flags:
+
+```text
+--secure-boot       build Secure Boot-capable ISO flavor
+--secure-boot-dev   build with local test keys for QEMU only
+```
+
+Pass mode and signing configuration into the Docker build environment.
+
+### `builder/build-iso.sh`
+
+Add Secure Boot build support:
+
+- Copy shim artifacts into the UEFI boot path.
+- Build live UKI.
+- Sign live UKI and second-stage EFI artifact.
+- Fail official Secure Boot builds if release signing material is unavailable.
+- Write `/root/omarchy_secure_boot_mode` into the live environment.
+- Assert that Secure Boot boot entries do not point at unsigned payloads.
+
+### `builder/secure-boot/`
+
+Add non-secret Secure Boot build inputs:
+
+- Public release certificate.
+- SBAT template.
+- Artifact manifest with expected shim/MokManager checksums.
+- Developer test-key generation script for QEMU only.
+
+Do not store private keys in this directory.
+
+### `configs/airootfs/root/configurator`
+
+Add Secure Boot detection and UX:
+
+- Detect UEFI Secure Boot state through efivars and/or `mokutil --sb-state`.
+- Detect Windows through ESP vendor paths and partition metadata (the dual-boot path's `detect_windows_esp` and BitLocker checks already exist — extend, don't duplicate).
+- Explain one-time MokManager enrollment.
+- Write `secure_boot.sh` with simple shell state for the install orchestrator.
+
+Example state:
+
+```bash
+SECURE_BOOT_ENABLED=true
+SECURE_BOOT_INSTALL=true
+SECURE_BOOT_BOOTLOADER=systemd-boot
+SECURE_BOOT_UKI=true
+SECURE_BOOT_MOK_COMMON_NAME="Omarchy Machine Owner Key"
+```
+
+### `configs/airootfs/usr/share/omarchy-iso/orchestrator/`
+
+Add Secure Boot install support to the install phases:
+
+- Read the `secure_boot.sh` state the configurator wrote.
+- When `SECURE_BOOT_INSTALL=true`, install the shim boot path and the enforcing second stage instead of (or in front of) the plain Limine setup in `_configure_limine_boot`.
+- Generate the machine-local MOK keypair on the installed encrypted root.
+- Sign the UKI that `finalize_limine_boot` already builds.
+- Schedule MOK enrollment with `mokutil --import`.
+- Install the UKI signing hook alongside the existing mkinitcpio hooks.
+- Preserve dual-boot firmware boot order unless explicitly promoted.
+- Extend `validate_boot` to assert the UKI on the ESP carries a valid signature.
+
+### Target System Files
+
+Add installed files similar to:
+
+```text
+/etc/omarchy/secure-boot.conf
+/etc/kernel/cmdline
+/etc/pacman.d/hooks/90-omarchy-uki.hook

+/boot/EFI/Linux/omarchy-linux-fallback.efi
+```
+
+Exact paths can change during implementation, but signed boot artifacts must stay under Omarchy-owned ESP directories.
+
+## Package Requirements
+
+Live ISO and installed Secure Boot path need tools for:
+
+- Building UKIs.
+- Signing PE/COFF EFI binaries.
+- Importing MOK certificates.
+- Inspecting Secure Boot state.
+
+Candidate packages:
+
+```text
+sbsigntools
+efitools
+mokutil
+openssl
+systemd
+```
+
+Validate Arch package availability before implementation. Do not assume an official Arch `shim-signed` package exists.
+
+## Dual-Boot Policy
+
+On Windows dual-boot machines:
+
+- Never modify Windows boot files.
+- Never clear or change TPM state.
+- Never change BitLocker protectors.
+- Preserve existing firmware default boot order by default.
+- Warn that adding a boot entry or changing ESP contents can trigger BitLocker recovery.
+- Follow the shipped dual-boot policy: tell users to turn BitLocker off in Windows and let the drive finish decrypting before installing (the configurator already enforces this; suspending alone proved insufficient — see #105).
+
+If the user chooses to make Omarchy first in boot order, capture the old `BootOrder` and provide rollback guidance.
+
+## Security Model
+
+Protected against:
+
+- Offline replacement of unsigned kernels on the ESP.
+- Offline modification of initramfs or kernel command line when UKI signature verification is enforced.
+- Accidental boot of unsigned Omarchy boot payloads in Secure Boot mode.
+
+Not protected against in v1:
+
+- A compromised running root user signing malicious future UKIs with the local MOK key.
+- Evil-maid attacks that trick the user into enrolling a malicious MOK.
+- Attacks requiring TPM-measured boot or remote attestation.
+
+Mitigations:
+
+- Store local private key only on encrypted root.
+- Make MokManager enrollment instructions explicit and brand-specific.
+- Display expected certificate fingerprint before reboot.
+- Keep release signing key outside shipped media.
+- Keep SBAT metadata current for revocation response.
+
+## QEMU Validation
+
+Use QEMU with OVMF Secure Boot enabled and test keys enrolled.
+
+Test matrix:
+
+1. Secure Boot ISO boots with test shim/test db in OVMF.
+2. Unsigned live UKI fails to boot.
+3. Tampered live UKI fails to boot.
+4. Secure Boot install completes to empty disk.
+5. First installed boot enters MokManager enrollment flow.
+6. After MOK enrollment, installed Omarchy boots and prompts for LUKS unlock.
+7. Tampered installed UKI fails to boot.
+8. Kernel update regenerates and signs a new UKI.
+9. Failed signing leaves previous UKI bootable.
+10. Dual-boot disk with Windows-style ESP preserves `EFI/Microsoft` and boot order.
+
+QEMU cannot fully prove Microsoft production trust. Hardware validation is required with firmware that trusts Microsoft UEFI CA and has Secure Boot enabled.
+
+## Hardware Validation
+
+Minimum hardware tests:
+
+1. Microsoft Secure Boot enabled laptop boots official Secure Boot ISO.
+2. Windows dual-boot install preserves Windows boot.
+3. BitLocker-decrypted install boots both OSes cleanly afterward.
+4. BitLocker-active install warning is visible before any disk mutation.
+5. Installed Omarchy boots only after MOK enrollment.
+6. Secure Boot remains enabled after install.
+7. Kernel update boots with newly signed UKI.
+8. Manually tampered UKI is rejected.
+9. Firmware boot order is preserved unless user opted to promote Omarchy.
+
+## Rollout Plan
+
+### Phase 1: Research And Decisions
+
+- Kick off the EV certificate purchase and `shim-review` submission prep immediately — this is the calendar-bound item that gates Phase 4, and nothing else depends on it being done first.
+- Confirm shim submission requirements and timeline.
+- Confirm selected second-stage boot manager (systemd-boot unless Limine's signature enforcement is proven).
+- ~~Confirm UKI generation mechanism on Arch~~ — resolved: mkinitcpio already builds the installed UKI today.
+- Confirm package availability for signing and MOK workflows.
+- Decide local MOK key storage and update-hook policy.
+- Decide the DKMS/out-of-tree module signing story (see Open Questions — this is a v1 blocker, not a nice-to-have).
+
+### Phase 2: Dev Secure Boot In QEMU
+
+- Add dev keys and QEMU OVMF Secure Boot harness.
+- Build a dev-signed live UKI.
+- Boot ISO in QEMU with test keys.
+- Prove unsigned and tampered payload rejection.
+
+### Phase 3: Installed UKI + MOK Flow
+
+- Generate local MOK key during install.
+- Build and sign installed UKI.
+- Schedule MokManager enrollment.
+- Boot installed system in QEMU after enrollment.
+- Add kernel update hook and fallback UKI handling.
+
+### Phase 4: Official Shim And Release Signing
+
+- Build Omarchy shim with SBAT metadata and embedded release cert.
+- Submit shim artifacts for Microsoft signing.
+- Integrate signed shim artifacts into official build pipeline.
+- Add release signing with HSM/offline key handling.
+
+### Phase 5: Consumer Dual-Boot UX
+
+- Add Secure Boot and BitLocker warnings to configurator.
+- Preserve Windows boot order by default.
+- Add MOK enrollment instructions and certificate fingerprint display.
+- Validate on real Windows hardware.
+
+## Acceptance Criteria
+
+- Official Secure Boot ISO boots on Microsoft Secure Boot hardware without disabling Secure Boot.
+- Secure Boot install does not ship or expose Omarchy release private keys.
+- Installed Omarchy boots through shim after MOK enrollment.
+- Installed Omarchy root remains LUKS-encrypted and passphrase-unlocked.
+- Kernel updates produce signed UKIs automatically.
+- Tampered UKIs fail to boot.
+- Windows ESP contents are preserved.
+- Windows boot order is preserved by default.
+- Secure Boot mode never offers an unsigned kernel/initramfs boot entry.
+
+## Open Questions
+
+- Whether Limine can enforce signature verification on the UKIs and config it loads; if not proven, Secure Boot installs use systemd-boot as the second stage while non-Secure-Boot installs keep Limine.
+- Whether the local MOK private key should be encrypted with a user-supplied passphrase or stored root-only on encrypted root.
+- How to support signed out-of-tree kernel modules, especially proprietary GPU drivers or DKMS packages. **This must be answered for v1:** once Secure Boot is enforcing, unsigned modules will not load, and NVIDIA laptops are exactly the consumer hardware this plan targets. The module signing hook must sign with the machine-local MOK alongside the UKI.
+- How snapshot booting (factory reset restores from Btrfs snapshots) should work when each bootable kernel must be a signed UKI.
+- Whether official builds should always be Secure Boot-capable or ship a separate Secure Boot ISO flavor.
+- What user-facing recovery path should exist if MOK enrollment is skipped or fails.
