Aus dem Log (q="Königsberger klopse"): 11 rezeptwelt-Treffer kamen durch alle URL-Filter, wurden aber von hasRecipeJsonLd als non-recipe gedroppt. Ursache: rezeptwelt.de nutzt Microdata (itemtype=schema.org/Recipe) statt application/ld+json. - hasRecipeJsonLd → hasRecipeMarkup: prüft jetzt zusätzlich per Regex auf itemtype=(https?://)schema.org/Recipe. Alter Export bleibt als Deprecated-Weiterleitung erhalten. - Log zeigt jetzt auch die ersten 3 gedropten URLs als dropped samples, damit neue Problem-Domains einfach zu diagnostizieren sind. - Migration 010 räumt alle thumbnail_cache-Einträge mit has_recipe=0 aus — die waren mit dem alten Check falsch-negativ und müssen neu klassifiziert werden. Tests: 4 neue Cases für hasRecipeMarkup (JSON-LD, http/https Microdata, Negativ-Fall). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
