Context Before

NVIDIA could also opt to deploy wider racks instead as is the case of AMD’s Helios rack, but

Evidence

this could affect the signal integrity on the PCB as electrical signals will have to traverse a longer path.

Context After

② Atomic Claim

採用更寬 rack 也可能影響 PCB 上的 signal integrity，因為 electrical signals 必須走更長的 path。

④ Canonical Entity Mapping

Role	Surface Label	Canonical Target
entity	PCB	PCB

⑤ Human Review

請在 Properties 逐項確認：

• 原文 → Atomic Claim 是否忠實
• Atomic Claim → Semantic Frame 是否忠實
• Canonical Entity mapping 是否正確
• Epistemic mode 是否保留原文語氣
• 最後選擇 review_action
