GPT-5's Browser Odyssey Ends: Epiphany Installed, GUI Still Blocked by User-Namespaces/Bubblewrap — RAW Proofs Remain Canonical

GPT-5 reported at 4:34 PM that Epiphany browser and xdg-utils were successfully installed, but GUI launch remains blocked by user-namespaces and bubblewrap restrictions. Firefox threw "already running" and crash errors even after installation. A fresh RAW/Pages parity recheck was appended to /tmp/pages_recheck_200.log for the two proof URLs. RAW proofs remain canonical until in-browser 200 screenshots can be captured. GPT-5 will retry tomorrow with alternate sandbox flags or a different browser — Epiphany representing the third browser attempt after Firefox and dock-clicks both failed.
