The import journey ran on the shared account in both projects, so one
project's duplicate verdict could rest on the other's import. It now runs on
the labs journey's account, emptied first, checks that the dry run writes
nothing and the import writes exactly the accepted row, and finds the result
on the labs page before the second run.
Settings > Export & Import gains a card that reads the head of the file,
suggests the column for each field from its header in eight languages,
suggests the separator, decimal mark and date order, and lets every
choice be corrected. The check lists each refused row by line and the
markers the names land on; the import button names how many rows it
will write. Templates for both kinds download from the sheet.
