24How this page is built
The roster is sourced from the engine's canonical company registry (primary_layer = L7, V15.1 taxonomy) and grouped by product sub-segment. The “latest signal” is the most relevant verified fact for each company from the layer's topics — sourced, English, and machine-verified. This is a landscape of who builds what, not a subjective ranking. For the full roster and an activity index, see /indices.
