ZOOMSYNTH reconstructs packet-level traces from second‑level counters by stacking a transformer that models trends with an extreme‑value branch into a tree of upscalers, enabling multi‑stage super‑resolution. The system uses GTT modules assembled into a CLTM tree, adds a CLIP‑style rule adaptor for ACLs, and releases a 1.8B pretrained model trained on 16 GB (expanded to 1.7 TB counters). Results show quality comparable to packet-input baselines, real‑time synthesis at up to 1e9× upscaling within one second, +27.5% anomaly detection and +9.8% service recognition gains.
