① SA Source

• Source: 開啟完整 SA 文章
• Section: STX
• Line hint: 383

Context Before

BF-4 in STX. Source: Nvidia, SemiAnalysis

Evidence

Unlike the BF-4 in the VR NVL72, which consists of a Grace CPU and a single CX-9 NIC, the BF-4 in the STX reference design includes one Vera CPU, two CX-9 NICs, and two SOCAMM modules. Each STX box contains two BF-4 units, totaling two Vera CPUs, four CX-9 NICs, and four SOCAMM modules. For the whole STX rack, it has a total of 16 boxes, implying 32 Vera CPUs, 64 CX-9 NICs, and 64 SOCAMMs.

Context After

② Atomic Claim

每個 STX box 含兩個 BF-4 units。

④ Canonical Entity Mapping

Role	Surface Label	Canonical Target
entity	STX	04_knowledge_base/NVIDIA STX Reference Storage Rack
context_0	BF-4	BlueField-4

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
