Lost a firm date
Launches whose firm date was replaced by a placeholder period
Placeholder rolls and firmings (recorded, not slips)
Launch Library parks an undated launch at the end of a period (“NET 2026” is stored as Dec 31, 2026). When that placeholder moves, nothing was announced and nothing slipped, so these rows are listed for completeness and never counted.
Caught up: changes our sync saw late (not counted)
These date changes were recorded in this period but did not happen in it: the launch was outside the part of the manifest our sync was refreshing when its date changed, so we only saw the change later. They are listed so nothing is hidden, and are in none of the figures above.
