Context Before
Rubin CPX was originally architected as a GDDR7-based accelerator optimized for prefill, based on three key considerations:
Evidence
Context After
HBM’s increased bandwidth is structurally underutilized in prefill.

③ Semantic Frame

}④ Canonical Entity Mapping
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
Prefill 主要受 FLOPs 限制，而不是 bandwidth 限制，因此 HBM 的不可替代性較低。

}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

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