docs/GLASS_COCKPIT.md gains the step-4 ledger (seam/transport/lobby + THE FAKEIP LESSON); NEW context/steam-networking.md topic (+ router row) and docs/STEAM_TEST.md (the 2-machine live procedure = the step-4 exit criterion on user hardware). context/glass-cockpit.md: steps 3+4 status. Final purity re-check: pod build clean, forced-walk mission runs, ZERO glass/steam tags in the pod log. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
