$ / oz	price	premium	metal content	dealer	product	price is for	captured

no rows match

$ / oz is the price of one troy ounce of contained metal — it puts a $45,000 monster bag and a $64 round on the same axis. Premium is computed live against each product's own metal and weight, resolved from its title — never stored, so it cannot go stale. Freshness measures when a source was last successfully fetched, not when a price last moved — under write-on-change those are different questions. Sources not seen in 3x their cadence are excluded from rankings, not merely greyed. Products whose metal content can't be determined show — rather than a wrong number.
Freshness compares each row's capture time to its source's expected cadence: fresh aging stale — excluded from rankings
