The Queue page reports what upload already did

All 36 version updates landed and all 36 still read as outstanding:
to_add.csv and to_update.csv are diff-time snapshots that never shrink,
and the page showed them without consulting the upload log. Rows now
carry their last attempt's outcome — pending / done / failed, plus
"retired" for jobs a later review decision withdrew — and each section
heads with a tally instead of a raw row count. A note explains that
finished rows persist until the next diff rebuilds the queue, and that
the log is the permanent record.

On Eric's data: to_update now reads 36 done, 0 pending.
