The Driver: a public plugin that is not yet a production map shows under Experimental until it is. A
profile's .meta.json declares "stage": "production" | "experimental" (default experimental; a bundle is
production if any profile says so) and "heavy": true for a live WebGL owner. generate-tree carries both into
manifest.json, so the Studio and the gallery read the same field and neither keeps a list.
The seven production bundles are marked: dashboard-plus-grid, research-map-plus-grid, regions-dashboard,
my-upg-100-list, doxa-simple-map, cities-internet, gospel-resources. The Studio rail keeps its capability
sections for them and puts every experimental bundle (gospel-internet among them) in one final Experimental
section. The gallery's auto-discovered Experimental folder skips a production bundle. gospel-internet-board
joins HEAVY_ELEMENTS (it can own two WebGL contexts). check:studio-rail asserts the split.
