Immutable event values. `Gap.after` is the last cursor delivered to the caller. Unknown loss is `None`. A gap ends continuity and is followed by End; recover with a fresh capture and a new subscription. Data preserves bytes, including NUL and invalid UTF-8. It is future observed output, not rendered text or historical reconstruction.
