xPRIMEray Visual Milestone Inventory

Historical archaeology pass — rendered outputs, diagnostic overlays, and milestone images from the xPRIMEray repository. Organized chronologically. Separates live engine capability from engineering harness and post-process analysis.


Era 0 — First Light: Interactive GRIN Rendering (Feb 2026)

The earliest screenshots show xPRIMEray operating as an interactive Godot scene: GRIN field bending visible in real-time, multiple field sources active, camera movement captured.
