A valid request must present a well-formed UUID-v4 in the path segment {session_id} AND a first-party Origin/Referer (or none). Requests carrying a known-foreign Origin/Referer are refused 403. Per-IP rate limiting applies. All responses carry Referrer-Policy: strict-origin-when-cross-origin.'

Recorded signatures are enforced server-side (helper `nda_signed`), not by trusting a client header.'
