-## CachyOS with Steamify Live ISO
-CachyOS 26.08 with Steamify built in: install CachyOS and turn the PC into a Steam Machine in one go.
-Its version is the Steamify version on it plus the build date and time (UTC, when the release starts on GitHub; a release on `master` is `v<Steamify version>-<date>-<HHMM>`, e.g. `v2.9.3-2026.09.29-2015`). A new Steamify release starts one (a test build for now); by hand: Run workflow on "ISO 1/2 · Tag and release (GitHub)".
-Releases: GitHub creates the tag and a release with the notes; the ISO itself (over GitHub's 2 GB limit) is built on the Gitea mirror and attached to its release for that tag (git.upriser.nl).
-
-**Features:**
-
-* **ISO:** named after its release tag (`steamify-cachyos-2.9.3-2026.09.29-2030-x86_64.iso`; built by hand, without a tag: `local`), labelled after the Steamify version on it and the build time (`STEAMIFY_2_9_1_20260929_1432`, was CachyOS's `COS_<year><month>`); CachyOS Hello installs it like CachyOS's own
-  release (the ISO's own release, its tag without the v, is in `/etc/steammachine-iso-build` and the boot menu)
-* **Installer (CachyOS - Steamify Installer):**
-  * A Steamify page after the packages page: which Steam Machine parts to set up (rows from
-    `steamify.sh --defaults --list`, the newest Steamify fetched before Calamares starts) and where
-    the PC starts (gaming mode or the desktop)
-  * The Summary lists every chosen item and where the PC starts
-  * The new user's Steam Machine setup runs during the install (`steamify-install`, a Calamares step
-    before cleanup): the first boot is already a Steam Machine
-  * Only what Steamify supports is offered: KDE Plasma, and the boot loaders Limine, systemd-boot and
-    GRUB (not rEFInd)
-* **Live session:** keeps CachyOS's own name; the power-off fix is built for the ISO's kernels, and
-  the login has the Vapor look
-
-**Fixes:**
-
-* **systemd-boot:** the installed system gets its "Linux Boot Manager" EFI boot entry, first in the
-  boot order. cachyos-installer runs `bootctl install` in a chroot, where bootctl leaves the EFI
-  variables alone, so the entry was missing: the PC could only boot through the disk's fallback path
-  (`\EFI\BOOT\BOOTX64.EFI`). Most PCs find it early and boot normally, but firmware that tries the
-  network first waits minutes on every boot (QEMU/OVMF: PXE, HTTP boot and the EFI shell come first),
-  and anything else that writes the fallback file (another OS) takes the boot over.
-  `steamify-install` now registers it with `efibootmgr` from the live system, with the ESP's real
-  disk and partition (bootctl in the chroot writes an entry without a partition, which the firmware
-  can't load); the output is in `/var/log/steamify-bootentry.log`
-* **Installer:** Steamify's install-time logs (`/var/log/steamify-install.log`,
-  `steamify-bootentry.log`) are readable after the first boot: `/var/log` is its own btrfs subvolume
-  (`@log`) that wasn't mounted yet when Steamify ran, so they ended up hidden under it
-* **Installer:** Steamify's setup never asks for a password (its sudo rule is read after CachyOS's
-  `%wheel` rule); Calamares starts with the Boost version it was linked against
-* **Build:** finishes cleanly as root and reports no error after a successful build; the Steamify page's
-  Calamares module is built with the ISO and left out when Calamares' version differs

-  `--fremont`, Start in: desktop): Summary listed the choices, the

-  CachyOS's Calamares source against the current `cachyos-calamares-next`
-  (no prebuilt `.so` in git), with `built-for`; `calamares-online.sh` leaves
-  the Steamify page out when the Calamares it runs differs (the step then
-  installs everything on) instead of risking "Initialization Failed".
-- **Steamify 2.6.0** released (`--defaults`, install-time mode).
-- **Live session** (VM, `--fremont`): Vapor look and layout (Steam Deck
-  wallpaper) at the live login; the power-off module is built for both ISO
-  kernels and loaded at boot, in the VM it returns "No such device" (no
-  AMDI0030 GPIO controller), as designed. Whether it keeps the real Steam
-  Machine off is part of the hardware test.
-- **Regression test 2.6.0 on an existing desktop install** (test VM from
-  ssh-ready, `--fremont`): full first run, re-apply, notifications/CEC/theme
-  off and on again. No errors; user units enabled and running, theme applied
-  and restored live, no first-login autostart with a session.
-- **ISO name**: `steamify-cachyos-<date>-x86_64.iso` (`iso_name` in
-  `archiso/profiledef.sh`); the volume label stays `COS_<yyyymm>`.
-- **VM install from the ISO (2026-09-27, `f42859a`):** a VM install from the ISO (Hello's
-  Install, no manual fixes) ran Steamify's step: every component OK,
-  `exit: 0`, SDDM autologin into gamescope. First desktop login (session switched to plasma in the VM) passed too:
-  Vapor layout, the app opened with everything on. The first-login script
-  runs the newest *release*, so it only works once 2.6.0 is released (in the
-  test it was pointed at the bundle).
-  The VM's text
-  console doesn't show (virgl): read the installed disk with
-  `qemu-nbd -r` + `mount -o ro,rescue=nologreplay,subvol=@` (logs in `@log`).

+- [x] **Always from `master`**: `iso-1-github-tag.yml` takes `kind` (release, dev, auto); steamify-cachyos' `bundle.yml` asks
+      for `release` (a version published from main) or `dev` (an unreleased version on a release branch).

+- [x] **`steamify.nodownload`** (kernel command line) or `STEAMIFY_NO_DOWNLOAD=1`: the live session keeps the ISO's own Steamify
+      (`calamares-online.sh` would replace it by the newest release), and `steamify-install` passes it on, so the installed system's
+      first login runs the ISO's bundle too. For testing an unreleased Steamify; tested with Steamify 2.11.0 (three installs).
+- [x] **The mirror's build is started by dispatch** after the mirror has the new tag object (a replaced tag starts no run by

+- [x] **Build badge** in the GitHub release: running, then succeeded / failed / cancelled (secret `GH_RELEASE_TOKEN` on the
+      mirror), linked to the public Gitea run.
+- [x] **Generated release notes** and title (`CachyOS <base> with Steamify <version> (<date> UTC)`): base version, Steamify's
+      changelog section, commits since the previous release; the mirror's release uses the same text.
+- [x] **Retention** of at most 10 dev and 10 real releases, deleting the mirror's release with its ISO too (PR #22; first
+      clean-up still to be seen, above).
+- [x] **Old hand-written `CHANGELOG.md` section** (`## CachyOS with Steamify Live ISO`) removed: the release notes are generated.
+- [x] **Same-day replacement of a real release** (2026-09-30): the official build for `v2.9.6-260930` replaced the test build's
+      release on the mirror (ISO asset 42 -> 50, new title and generated notes, badge green with the public run link).
+- [x] **Release notes** leave out the workflow and docs commits (`ci`, `docs`, `…(ci):`) in their list of ISO changes.
+- [x] **The ISO is built on the Gitea mirror's runner** (`iso-2-gitea-build.yml`) and hosted there (over GitHub's 2 GB limit);
+      the VM tests run locally (`scripts/vmtest.sh --install` in steamify-cachyos-dev), not on the runners.
+- [x] **Build in the test VM instead of on the Steam Machine**: superseded by the runner above.
 
-- **Branding**: only the installer carries Steamify's name; check with the
+### Installer, live session and Steamify (2026-09-27 to 2026-09-29)
-  CachyOS team whether that and the ISO file name are fine with them.
