First-party · SDK from edge
SDK and every ID5 call served first-party from edge.pakopress.dev (same registrable domain as the page). The variant that survives iOS 27.
Third-party · SDK from edge
SDK and calls served from the ID5-hosted edge edge.eu-2-id5-sync.com (third-party). Not on the iOS 27 block list; stop-gap for partners without the publisher's domain.
First-party · SDK from jsDelivr
SDK loaded from jsDelivr (neutral CDN); dynamic calls go first-party to edge.pakopress.dev. The edge handles only the calls.
Third-party · SDK from jsDelivr
SDK loaded from jsDelivr; dynamic calls go to the ID5-hosted edge edge.eu-2-id5-sync.com (third-party).
/a7q3 is the per-deployment proxy prefix. The first-party pages need an edge on
edge.pakopress.dev/a7q3/*; the third-party pages need edge.eu-2-id5-sync.com/a7q3/*.
partnerId: 173 is a placeholder; consent is static for the demo.
