Artifact comments can name which page of a multi-file artifact they're attached to.
Page anchors in comment listings are only emitted when an internal flag is on.

What
Comment listings can carry a marker naming the file, that is the page, of a multi-file artifact a thread is anchored to, with a separate row when that anchor could not be read during a fetch. The preamble that introduces a comment block was extended to explain that only the marker line comes from the tool and everything after it is data from the viewer. This section of the Artifact description is emitted only when its internal flag is on.
