Technical specifications retain the source’s original units and evidence status. Hardware counts, compute rates and power are not equivalent; launched hardware does not establish demonstrated performance. Supplier counts include suppliers and hosts only, reflect current filters and cover this directory, not the entire market. “No record” means no disclosure captured; it does not mean the work is unawarded. Latest developments use source dates, not routine review or collection dates.
