The Type column reflects the data feed's event category (for example stock split vs stock dividend). When the feed labels a generic split but the ratio is reverse (e.g. 1:10), we show reverse stock split. Optional editorial context for a row appears next to the split ratio as an info icon (hover or keyboard focus on desktop; tap on mobile). The same text is listed under Row notes when that block is expanded.
