nx_cdmap_export_gate.nx

nx_cdmap_export_gate.nx -- referee for the position map's EXPORT (datavis DV6, nx_cdmap_raster_lib, 2026-09-15). A planted page carries a :root token block and a small cdmap svg with one of every construct the emitter writes (frame rect with stroke, dashed gridline, momentum polyline with the arrow marker, filled polygon, a bubble with a translucent fill and a momentum ring, a bold haloed label, anchored axis titles, a -90 rotated title, a cdnote group, an uppercase muted quadrant word, a rotation the subset does not draw, and an element outside the subset). The gate composes the library IN-PROCESS and holds the render to the pixels: the token colours land where the elements are, the translucent bubble blends by the declared opacity, the dash is ON where the phase says on and OFF where it says off, the arrow tip is ink, the labels leave dark ink in their boxes, the rotated title leaves ink in a vertical band, and every count on the stats record equals the fixture's census. Both files are then written through rs_export and read back (PNG signature and IHDR dimensions; SVG namespace present and every colour variable resolved). Negative controls drive the named refusals (no figure, no tokens, no font, a scale out of range) and a determinism tooth renders twice. When the live search page is on disk it is exported to /tmp and announced through gv_kv, never gv_need. license_tier: ORIGINAL
