Context Before

Illustratively, consider two hypothetical VR NVL deployments with 1.6T and 800G logical ports respectively. A 1-plane, 3-layer network with one 1.6T logical ports achieves only a maximum cluster size of 93,312 GPUs, or:

2(115,2001,6002)3=2(722)3=93,312

Evidence

By one 1.6T logical port, we mean that the two 800G OSFP cages connected to each GPU are connected to a single, dual-port 1.6T transceiver at the leaf layer because the two 800G ports are effectively performing the function of one 1.6T port – and hence the term “logical”.

② Atomic Claim

所謂 1 個 1.6T logical port，是指每顆 GPU 連接的 2 個 800G OSFP cages，在 leaf layer 接到單一 dual-port 1.6T transceiver；因為兩個 800G ports 實際共同執行一個 1.6T port 的功能，所以稱為 logical。

⑤ V2 Draft（需要修正時直接編輯）

Inline repair

只編輯以下三個 Draft 區塊。完成後將 review_action 設為 REQUEST_REPAIR，再手動執行 Repair Preview。
執行腳本前，Draft 不會寫入 Claim Store 或 Graph。

⑥ 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
