07 Remediation
Update to a build including commit ec97209, which moves revalidateProducts out of the file-scoped "use server" module into a server-only module and restricts its only network-reachable caller (GET /api/cron/catalog-sync) with an internal credential check. Do not export unauthenticated mutations from a file-scoped "use server" module; gate any cache-invalidation action behind an admin/session check or remove the client-callable export entirely.
