            time.Sleep is forbidden.
            In tests: use assert.EventuallyWithT for polling/waiting patterns.
            In production code: use a backoff strategy (e.g., cenkalti/backoff) or proper synchronization primitives.

            Use zf.* constants for zerolog field names instead of string literals.
            Import "github.com/juanfont/headscale/hscontrol/util/zlog/zf" and use
            constants like zf.NodeID, zf.UserName, etc. Add new constants to
            hscontrol/util/zlog/zf/fields.go if needed.
