-When invoking `navigator.runAdAuction()`, `directFromSellerSignalsHeaderAdSlot` is used to lookup the signals intended for that auction. `directFromSellerSignalsHeaderAdSlot` is a string that should match the `adSlot` value contained in some `Ad-Auction-Signals` response served from the origin of that auction's seller. Note that for multi-seller or component auctions, each component auction can specify its own `directFromSellerSignalsHeaderAdSlot`, and the response should be served from that component auction's seller's origin. Different sellers may safely use the same `adSlot` names without conflict. If `directFromSellerSignalsHeaderAdSlot` matches multiple `adSlot`s from header responses, one of those `adSlot` responses will be chosen arbitrarily.

Note that for multi-seller or component auctions, each component auction / top-level can specify its own `directFromSellerSignalsHeaderAdSlot`, and the response should be served from that component / top-level auction's seller's origin. Different sellers may safely use the same `adSlot` names without conflict. If `directFromSellerSignalsHeaderAdSlot` matches multiple `adSlot`s from header responses, one of those `adSlot` responses will be chosen arbitrarily.
 
 The JSON will be parsed by the browser, and passed via the same `directFromSellerSignals` worklet functions parameter as in [the subresource bundle](#251-using-subresource-bundles) version of DirectFromSellerSignals, with `sellerSignals` only being delivered to the seller, `perBuyerSignals` only being delivered to the buyer for each buyer origin key, and `auctionSignals` being delivered to all parties. Since the top-level JSON value is an array, multiple `adSlot` responses may be set for a given Ad-Auction-Signals header.
 
-Since both `directFromSellerSignals` and `directFromSellerSignalsHeaderAdSlot` (the parameters on `navigator.runAdAuction()`) set the same `directFromSellerSignals` parameter on the worklet functions, it is not valid to use both `directFromSellerSignals` and `directFromSellerSignalsHeaderAdSlot` in the same auction. However, component auctions in the same top-level auction do not all need to use the same type of DirectFromSellerSignals (and it's also valid if only some component auctions use DirectFromSellerSignals).

 Failure to find a matching `adSlot` results in the fields of the `directFromSellerSignals` object passed to worklet functions being set to null, similar to the [subresource bundle version](#251-using-subresource-bundles).
