Errors

abox.ErrGuestTooOld on the one SDK, pkg/abox.

Demonstrates a missing golden image, then ErrGuestTooOld when Open hits a guest older than protocol 4.

CLI

Missing golden image:

abox --probe-vm
# guest image missing … (run: make image)

Old session disk (guest older than protocol 4):

abox --resume <id>
# guest protocol N cannot enforce brokered MCP and command approvals; rebuild the guest image and start a new session

make build && make image-update
abox                          # new session; do not resume the old id

--probe-vm can still list files on that old disk. Troubleshooting.
