"""The v4 task matrix: v3 plus what 1.6 added.

Track A added ``pid_roundtrip``; track E adds ``page_setup_truth`` — apply an
ISO A3 landscape page setup, plot through ``batch_plot`` and read the sheet
size back from the PDF's own ``/MediaBox``. The published competitor reports
were never asked either question and the chart shows them ``not_run`` — the
same rule v3 set for its five.
