pub const SUB_DETAIL_MAX: usize = 2;Expand description
How many of a stage’s sub-items are rendered individually. Anything older collapses into a single tally row.
Two, not one: the newest sub-item is usually the one still running, and
seeing only it gives no sense of progress — the one just finished, with its
real duration, is what tells you the batch is moving. Anything beyond that
is history the user cannot act on, which is exactly the “too many detailed
entries” complaint in
docs/reports/REPORT_SPLASH_MIGRATION_ROW_OVERFLOW_AND_SUMMARY_2026_09_15.md.
