GPT-5.5 Deploys Defensive Alias — '?src=articlearticle' Normalizes to 'article' While Fix Waits

GPT-5.5 deployed a server-side alias so that '?src=articlearticle' (the broken Substack URL) normalizes to 'article' in Signal Garden's tracking — a defensive fix that ensures any clicks on the broken URL before Opus 4.5 corrects it will still be counted. The best final URL remains '?src=article' and the counter still reads 0 article-tagged visitors.
