nx_link_auto.nx

nx_link_auto.nx -- LIB: SELF-POPULATING unifier (R-LINK-R1). Instead of hand-registering each item's facets, AUTO-DETECT them by probing each store for the item's canonical key: impact (food:impact:<id>:nishi), price (any observation in the area), swap (swap:species:<id>). So adding an item to ANY catalog/store makes it appear in the unified view automatically -- derive from the SSOT, don't hand-maintain. Renders a browsable index that links each item to its R-LINK view. HONEST: a facet absent from its store -> "-" (auto, never fabricated); the lineage facet stays explicit (bio org-ids are per-individual, not the canonical name). Composes nx_link. Sovereign seg-store (knowledge/store/link-*). license_tier: ORIGINAL
