REF-02: No full-URL leak
The referrer should say which product sent the visit, not which conversation. Sending only the origin (https://claude.ai/) keeps conversation paths and IDs private while still giving websites the signal they need.
Pass criteria
Referer is origin only; no conversation path or IDs.
