Fetch a public web page and return clean Markdown with stable citation anchors, a content
Fetch a public web page and return clean Markdown with stable citation anchors, a content hash, and a retrieval timestamp — plus evidence of hidden text, invisible Unicode, and prompt-injection attempts found in the page. Strict SSRF protection on every redirect hop. Returns a per-span verdict with the decoded payload, not a confidence score. Zero retention.
