Recency Priority

Work the active surface newest-first, ranked by each object's updated frontmatter date (fall back to file modification time when updated is absent). Concentrate scrutiny on the freshest material — recently-touched objects are where active thinking lives and where new mismatches, overlaps, and gaps appear. Long-untouched objects are assumed settled and rank lower, but are never excluded: they remain valid link targets, merge destinations, and canonical homes, and still get a structural check (broken links, orphaning).
