unprobed
Human or synthetic? Provenance evidence for a URL: archive first-capture date, domain age, authorship markup, curated source tier, AI disclosures and stylometric signals, aggregated into a calibrated 0-100 human-origin score with every piece of evidence. Add deep=true for an LLM stylometric assessment.
Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
