The download is Shadowfetch Linux 4.0.0. Firebreak on this image leaves address space unlimited and keeps MemoryMax at 3072 MiB, so the code-mode host no longer exits SIGTRAP. Fresh BIOS Fire and UEFI Ice Calamares installs from this ISO completed Core first-boot.
Supported wording: For the first time in Shadowfetch Linux, choose Grok Bot at startup.A broader world-first Grok-on-Linux claim is not established. Grok Bot needs an eligible account and internet.
Blender review exports with the approved gentle female narration. These are 4.0 review films. The 3.5 YouTube walkthrough further down the page remains historical.
The earlier C11 ISO a5391737ab4aaf65e20bbfd0313bd3854114245c4df870ea64bcc362add53bdadoes not contain the Firebreak VA/RSS split and is not the stable image. Candidate8 screenshots and the C8 45-minute stress run are not final-image proof of every remaining case.
PROVED ON THIS ISO
Signed ISO rebuilt after removing the Firebreak RLIMIT_AS pin.
Fresh BIOS Fire install, installed-boot, Core first-boot.
Fresh UEFI Ice install from the live Ice GRUB menu; sf.element=ice is present and Ice stays offline.
Firebreak RLIMIT_AS unlimited; RSS / MemoryMax still 3072 MiB; session/execute did not SIGTRAP.
Featured Grok Bot startup choice, with account and internet requirements kept visible.
Local AI deferred; Buzz retirement preserves user model, profile and volume data.
NOT CLAIMED ON THIS IMAGE
3.5-to-4.0 upgrade and Phoenix rollback were not repeated on this ISO.
The 45-minute concurrent stress run, full visual matrix, and evidence bundle are still pending.
The public APT snapshot still lists 3.5.0-1 first-party packages until the full artifact publisher runs.
QXL guests can show gpu-verify-failed / no DRM render node. That is the known VM caveat.
Grok vendor UI can still show a connection / Retry screen. Sign-in does not prove authenticated cloud work.
