Description

When the locations of VVRs are given to _read_vvrs(), it is assumed that they are in order, i.e.

VVR1 - Records 0-100
VVR2 - Records 101-200
VVR3 - Records 201-300

However, there is no requirement for VVRs to be in the "correct" order.

Research direction

Start by locating the _read_vvrs() entry point and read how it maps VVR locations to record ranges. Check whether existing tests cover VVR ordering; done means the reader handles VVRs supplied in an order different from their record ranges without changing the resulting records.
