   and `ensure-kernel-headers.service` installs missing ones at boot (a
   pacman hook can't run pacman), which triggers DKMS's install hook. The module creates
   `/sys/class/leds/valve-leds*`.
+- `bios` is an *action* (`ACTIONS` in `lib/menu.sh`), not an on/off
+  component: never preselected (not even on a first run), never re-applied
+  by `a`, not listed in the state overview, and `bios_status` is always off.
+  Only selectable when Valve's version differs from the installed one
+  (`component_selectable`, greyed out otherwise). Download, SHA-256 and the
+  fwupd device check (`get-details --json`: no `UpdateError`) come before the
+  warnings. The warning box uses `█` for its frame: Konsole draws a long
+  coloured row of `#` narrower, so the right edge wouldn't line up.
+  Keep both confirmations (y/N, then typing `UPDATE`) and the warnings; the
+  firmware comes from the newest `holo-X.Y` repo (`.files` db names the
+  `.cab`, `.db` gives the SHA-256), and fwupd itself refuses non-Fremont
+  hardware. In the VM, test it with `WIZARD_BIOS_DRY_RUN=1` (skips only the
+  device check, never flashes) and a faked version (dev-env
+  `BIOS_VERSION=F7F0107 ./run.sh --fremont`).
+- The entry point loops: menu, run, "back to the menu" (or `[m]`/`[r]` when a
+  restart is needed), until `q`; the restart question is asked once at the
+  end. Scripted input that runs out ends the loop like `q`.
 - `Relogin=true` means a gamescope that fails to start is relaunched in a
   tight loop; keep that in mind when changing session handling.
 
 ## Checking changes
 
+The bundle puts every module in one file, so shellcheck sees all their
+`local` variables together: don't reuse a name another module uses as an
+array (e.g. `g` in `lib/state.sh`), or CI's shellcheck on the bundle fails.

+An opt-in BIOS update for the Steam Machine, and a menu that comes back after
+every run.
+
+- `2f9b2a5` **feat: Opt-in BIOS update for the Steam Machine**
+  - New menu item (Steam Machine only, never ticked by default) showing the
+    current BIOS version and the newest from Valve's `fremont-hw-support`.
+  - Two large warnings and two confirmations (y/N, then typing `UPDATE`),
+    checksum-verified download, installed with fwupd; the wizard then offers
+    the restart that writes it, with a warning to keep the power on.
+- `40c9ee6` **fix: BIOS update only when newer, device check first, aligned warnings**
+  - The item is greyed out and can't be ticked unless Valve has a newer BIOS.
+  - Before any warning: SHA-256 of Valve's package, then fwupd confirms the
+    firmware fits this machine's hardware; otherwise it stops.
+  - Warning box drawn with a solid red frame whose edges line up, and the
+    menu's "Now" column aligned.
+- `b70c9d6` **fix: shellcheck in the bundle, and the docs for the BIOS checks**
+  - A variable name in `lib/bios.sh` clashed with `lib/state.sh` in the bundle
+    (CI's shellcheck would fail); README, AGENTS.md and this changelog updated.
+- `54fc9e3` **feat: Menu comes back after each run, BIOS dry run, version 0.8.0**
+  - After a run the menu returns with the new state; quit with `q`. When
+    something needs a restart, choose between back to the menu (`m`) and
+    restart now (`r`); quitting asks once more.
+  - A staged BIOS update greys the item out until the restart.
+  - `WIZARD_BIOS_DRY_RUN=1` walks through the whole BIOS update (download,
+    checksum, both warnings) but only prints the install and never flashes.
+  - README: the menu loop and the BIOS update step by step.
+- `45a8757` **fix: BIOS dry run also walks through the restart choices**
+  - A dry run counts as staged, so `[m]`/`[r]` and the restart question on `q`
+    show up; in dry-run mode restarting only prints what it would do.
+- `429e840` **fix: Shorter BIOS labels so the menu fits 80 columns**
+  - "now F7F0107, newest F7F0108 (own risk)", "F7F0108 waits for a restart",
+    "F7F0107 is up to date"; shorter dry-run line.

+
+It can only be ticked when Valve has a newer BIOS than yours; when you're up
+to date, when the newest version can't be looked up (offline), or when an
+update is already waiting for a restart, it's greyed out.
+
+When you run it, the wizard:
+
+1. downloads Valve's package and checks its **SHA-256** against Valve's
+   repository, so it's exactly Valve's file;
+2. asks **fwupd** whether the firmware is for this very machine (fwupd compares
+   the firmware's hardware IDs with the device) and stops if it isn't;
+3. shows a large red **warning** with the current and the new version, and asks
+   whether you understand the risks (default: no);
+4. shows the warning **again** and only continues when you type `UPDATE`;
+5. hands the firmware to fwupd, which writes it during the **next restart**:
+   choose "restart now" or restart later yourself.
+
+**At your own risk:** a failed or interrupted BIOS update can leave the machine
+unable to start. Keep it on mains power, and never turn off the power, unplug
+it or press the power button while it updates, including during the restart;
+the screen can stay black for several minutes.
+
+To walk through it without flashing anything, run the wizard with
+`WIZARD_BIOS_DRY_RUN=1`: it downloads and checks the package and shows both
+warnings, skips fwupd's device check, and only prints the install command.
