A point-in-time, fully-cited corporate relationship map from free official data (13F co-ownership · federal awards · legal hierarchy).
⚠️ Display-only context — every edge is cited, click any edge to open its source.
Sector edges are sector-level (not firm-to-firm); gov edges are prime-only (agency→firm).
This is not a signal — whether any relationship predicts returns is unvalidated (that's a later, backtested phase).
