Remarks
The structured filters live on Selection, which a lexical search applies too. What this type adds is the part that belongs to a timeline alone: the end it is read from, and the fingerprint a continuation cursor is checked against.
The reading direction belongs to the filter rather than sitting beside it, because a continuation cursor names a boundary in one total order over one filtered set. Treating the direction as a separate concern would let a cursor issued while reading newest-first be presented while reading oldest-first, which names a row and an arbitrary window around it. Fingerprint therefore covers the direction along with the filters.
