Context Before

STX

Evidence

To expand the scope of CMX, NVIDIA also launched STX. STX is a reference rack architecture using Nvidia’s BF-4 based storage solution to complement VR compute racks. The reference architecture effectively specifies exactly how many drives, Vera CPUs, BF-4 DPUs, CX-9 NICs, and Spectrum-X switches are needed for a given cluster.

② Atomic Claim

STX reference architecture 會明確規定一個 cluster 需要多少 CX-9 NICs。

• Epistemic Mode: ASSERTED
• Mapping Status: COMPLETE

③ Semantic Frame

{
  "additional_nodes": [],
  "frame_type": "RELATION",
  "object": {
    "id": "04_knowledge_base/ConnectX-9",
    "label": "CX-9 NIC"
  },
  "predicate": "SPECIFIES_REQUIRED_COUNT_OF",
  "qualifiers": {
    "condition_text": "given cluster",
    "numeric_mentions": [],
    "temporal_mentions": []
  },
  "subject": {
    "id": "04_knowledge_base/NVIDIA STX Reference Storage Rack",
    "label": "STX"
  }
}

④ Canonical Entity Mapping

Role	Surface Label	Canonical Target
subject	STX	04_knowledge_base/NVIDIA STX Reference Storage Rack
object	CX-9 NIC	ConnectX-9

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。

V2 Atomic Claim Draft

STX reference architecture 會明確規定一個 cluster 需要多少 CX-9 NICs。

V2 Semantic Frame Draft

V2 Revision Metadata Draft

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

Review state

Markdown 內文不是正式 approval。只有 Apply bridge 寫入的 Decision Ledger event 才是正式決策。
