Entity layer, not the claim layer — 22 districts with their real adjacency, 8 metro lines, the six interpretive layers and the six discourse anchors, and the contested claims as their own nodes. Neighbourhoods and sites are counted in their district (open a district for the list). Layer–anchor edges are the relational core: a layer engages an anchor when governed claims read through it turn on that anchor (thicker = more claims; dashed = thin, under 3 claims or one source). Orange dashed edges are literature gaps: no claim yet, but research on Tehran exists there (see triage/GAP_REPORT.md). Cells with neither are non-positions and are not drawn. A contested claim links to its place, its layer, its anchors and the claim it contradicts. Dashed edges are unverified — every metro district-coverage edge is dashed, because that mapping was never sourced. Drag a node to pin it, double-click the canvas to release every pin; click for detail; scroll to zoom. The layout settles and stops.
