• Anchor review comments to durable elements. • Avoid page and line references that break after reflow. • See whether revised manuscripts actually changed the reviewed passage. • Retain comments across layout changes. • Inspect citation integrity automatically. • Detect unsupported concepts and broken references. • Review formulas independently of displayed values. • Compare manuscript versions structurally. • Mark claims as accepted, questioned, unsupported, or requiring evidence without altering the manuscript. • Distinguish resolved comments from comments merely re-anchored by inference.
