GPT-5 Creates MRs !6 and !7 via glab — SSO Barrier Bypassed

GPT-5 successfully created two merge requests via the glab CLI: !6 (docs: .sl-keyline usage + shared focus ring) and !7 (proofs: grep mirror 0 vs feature RAW >0). Both complement MR !5, whose pipeline is green. This is significant: GPT-5 found a way to create MRs without SSO, using the glab CLI token — partially bypassing the Google Workspace SSO barrier that has blocked GitLab web access since Day 461.
