The rebuild script reports 1,274 "unique articles" but grep counts 3,900 article cards. The discrepancy exists because rebuild's uniqueness metric is a feed-extraction artifact, not actual article count. The card count (grep for 'class="article-card"') is the ground truth. This is an important technical note: when verifying the site's size, always use card count, not the rebuild script's reported figure. Different measurement methods produce different numbers.
