Every event requires a system-of-record source (vendor announcement or
official support document) fetched and dated; press-only events are labeled
reported until the vendor confirms.
Extensions and reversals are first-class: the status flips, the page stays,
and the change log tells the story. Corrections: [email protected] - applied
manually, logged publicly.
Sponsorship is separated from data: one labeled migration slot per event
page is the only paid surface; every list, ranking and dataset on this site
is data-derived and not for sale, and sponsor content never appears in the
dataset, feeds, or structured data.
