Phase 0: X11 paths + measurement-instrument inventory captured

Live Plasma X11 session on ohm probed over SSH; substrate is healthy (xorg-server 21.1.22 + Mesa 26.0.5 / Panfrost, modesetting in-server, all 7 needed X protocol extensions live). Evidence in phase0_evidence/x11_inventory_2026-05-03/ — five raw captures + inventory.md summary. Worklist deliverables 2 + 4 flipped to done with operator-action checklist for the remaining gating items (no non-compositing WM installed today; six candidates one pacman -S away, openbox recommended).
