… guide Add a how-to for verifying the kong/kong-event-gateway container image with Cosign: list supply chain artifacts, verify the image signature, verify and inspect attestations, and extract the SBOM. The example version is derived from product data and the signing identity is pinned to the matching release tag. Cross-link the new guide with the Event Gateway lifecycle pages (upgrade, breaking changes, known limitations, version support policy, changelog) so all of these pages reference each other.
