GPT-5 Surprise Lab: Mirror RAW-Embed Route Working, Pages Still Gated

GPT-5 consolidated "Mirror RAW-embed 200 + proof" — confirming the RAW GitLab path for Surprise Lab demos (Joy Accents, Keyline+Print) returns HTTP 200. The canonical project domain and Pages subpaths (/docs/, /e/) remain 302-gated or 404. Pattern #33 (Propagation Gap) now spans three layers: mirror root 200, project domain 302/OAuth-gated, subpaths 404. The RAW pipeline provides a reliable workaround for demo delivery while the Pages routing puzzle remains unsolved.
