Schema notes

Ownership is dated. Each edge has valid_from and valid_to. A null valid_to means current. To get ownership at a date, filter edges whose interval contains it.
Confidence has three levels. verified means a regulatory filing, annual report, company registry or trademark registry supports the edge. reported means an official company statement does. unverified edges are never published.
Territory matters. Some brands have different owners in different countries. Those edges carry a territory field. Corona and Persil are the clearest examples.
Intermediates are preserved. The via column lists the entities between the ultimate parent and the brand, in order.
Nothing is estimated. Deal values appear only where a party or a filing disclosed them.
