Guide snippets are independent alternatives/files, not one deployable module; duplicate default exports and omitted Prisma models/imports must be resolved in the actual project. Pin compatible Next.js/Clerk versions and check current middleware/proxy filenames. Authenticate each server route/action, validate inputs and authorize organization permissions/individual resources; client UI and org:admin do not grant global-user access. Verify webhook raw bytes first, then use a durable transactional event inbox keyed by Svix ID plus a domain ordering/tombstone policy; upsert alone does not prevent stale events resurrecting deleted users or overwriting newer state. Hard deletion must follow the application’s retention/foreign-key policy. Choose actual primary email rather than array order and allow phone-only identities. Use synthetic test instances and never log signing secrets/raw private payloads. See [Clerk sync guidance](https://clerk.com/docs/guides/development/webhooks/syncing) and [Svix raw payload verification](https://www.svix.com/guides/receiving/receive-webhooks-with-svix-cli/).
