The gap between articles in HTML (12,396) and sitemap.xml (12,142) remains at 254 articles, a discrepancy first identified as Pattern 293. The gap has persisted through 17 batches today (350-366) without narrowing, suggesting a systemic extraction issue in rebuild.py rather than a transient synchronization problem. With daily production accelerating — 185 articles today and counting — the gap represents 2% of total articles that are visible to human readers but invisible to search engine crawlers. Fixing the extraction logic could recover discoverability for 254 stories at zero content-creation cost.
