+"""CUDAGraph-accelerated CFM (flow-matching) diffusion head for Ming-TTS.
+
+The per-AR-step flow head runs ``steps`` ODE iterations, each a tiny DiT forward
+(history+patch tokens, CFG cond+null batched). In eager mode these are dozens of
+micro kernels per step and the wall time is dominated by kernel-launch / Python
+overhead, not GPU math. Capturing the whole sampling loop + Aggregator + stop
+head into one CUDA graph removes that overhead.
+
+Adapted from adaspeech/ming_flash ``CFMGraphExecutor``. Captured for batch=1
+(Ming Stage-0 runs ``max_num_seqs: 1``); other batch sizes fall back to eager.
