Case 15 — Comparison thread: 38mm vs 40mm versions of the same field watch, with a dated correction log

Before the table goes live, a question: are you comparing current production only, or older references too? Dial printing, lume colour and crown signing often changed between batches. If older pieces are in scope, add a production-period column, or every disagreement will look like an error when it's really a running change.
