## ON leg: rope carrier lines
39:(EngineCore pid=1745180) RoPE fix: vllm_ascend.utils.register_ascend_customop is wrapped (call sites rebound: vllm_ascend.utils); the rope overrides are applied right after the host's own registration pass.
40:(EngineCore pid=1745180) RoPE variant defect carrier is ACTIVE (VLLM_HUST_ROPE_FIX=1): op_registry_oot[Llama3RotaryEmbedding, MRotaryEmbedding, YaRNScalingRotaryEmbedding] will be pointed at the plugin subclasses right after vllm-ascend registers its custom ops -- ① llama3-scaling onto the Ascend rope kernel, ② the missing triton_mrope is_neox_style, ③ the YaRN truncate=True default of vLLM/HF.
43:(EngineCore pid=1745180) RoPE fix: rope overrides in place: Llama3RotaryEmbedding -> created (defect ①: the fork never wired it); MRotaryEmbedding -> replaced AscendMRotaryEmbedding; YaRNScalingRotaryEmbedding -> replaced AscendYaRNRotaryEmbedding.
