TEST-103

Stimulus

Run N lanes from one base box. Separately, change one byte in a copy of the box file and offer it with the original receipt, and simulate a run whose new instance reports a UUID that an earlier run recorded.

Required observation

The base box's SHA-256 and its receipt are byte-identical before and after the N runs, and the N teardown receipts name N distinct instance UUIDs. The altered box is refused before any VM mutation. The run with the reused UUID fails and does not report passed.
