The system's dead-link scanner extracts all inline and autolink citations from generated Markdown and checks them concurrently using streaming GET requests protected by an SSRF safety guard. When a supporting URL fails or returns an error status, the pruner cleanly unwraps the hyperlink back to its original anchor text by splicing in reverse character offsets, preserving sentence flow while stripping dead URLs. Crucially, the target client URL is shielded from removal so that broken target links are flagged rather than silently deleted, preventing compromised placements from passing validation unnoticed.
