To prevent hallucinated citations from degrading content quality, the engine uses ranged streaming HTTP requests with SSRF guards to check the status of all cited URLs, bucketing them into live, gone, or dead states without downloading full page bodies. When a broken URL is detected, the engine strips the hyperlink while preserving the anchor text as natural surrounding prose by replacing markdown syntax with the underlying text label, all while strictly shielding the target money link from deletion so placement failures properly fold the draft.
