-- B1: no check yet that the loader's own EFI entry exists, points to a real partition and was used
-  (`efibootmgr` `BootCurrent`): systemd-boot booted through the disk's fallback path unnoticed until
-  2026-09-29 (a 4-5 minute network boot per boot in OVMF). To add to `share/bootloader-test/`.
-- ISO: `/var/log` is its own btrfs subvolume (`@log`), not mounted at `$ROOT/var/log` when
-  `steamify-install` runs: its logs (`steamify-install.log`, `steamify-bootentry.log`) end up hidden
-  under the mount after boot.
+- CEC (B2, B5, B7, R1.7): the driver source is downloaded from raw.githubusercontent.com at setup time;
+  a GitHub rate limit (HTTP 429) fails CEC and every check that needs its module. Rerun later; fix in TODO.
