Second collision in one delivery: origin/staging advanced from c8d9ec64 to
e1db5762 while the test suite was running and claimed 256-259, so the three
records in this batch move to 260, 261 and 262 with their cross-references
updated. Titles differ from every remote record, so BUG-254's rule assigns new
numbers rather than merging.
BUG-260's related-records field now states the limit this exposes: searching
for the highest number before appending only holds at the moment of writing
and cannot survive the remote advancing before the push.
