The device ingest staged every reflection to the card twice - once for what the sort and the
cut read, once again for the observations the cut kept - and the second staging was a full
copy of the reflections into pinned memory and over the bus. Where the whole set of reflections
and the ingest's own peak beside it fit a quarter of the card (decided on the card's total
memory, so the answer depends on the card and not on the moment), the first upload now goes
into one resident copy, and the observations are taken from it in a single extract; the second
staging stays as the fallback where the copy does not fit, and where the card reads host
memory in place. The extract kernel also hands over the predicted positions, which the host
had gathered itself from a downloaded index array, and the two pinned staging buffers are kept
across the ingest instead of being allocated per staging. Same observations, same order, same
bits.
