VR-COV-VR-ECHO-CANCEL

回到這篇 SA Coverage

① SA Source

Context Before

B0+A0=BA0

An inverted copy of the local TX must therefore be generated at the local RX for proper echo cancellation:

Evidence

B0+A0=BA0+(−A0)=B0

Context After

The diagram below illustrates this dynamic:

② Atomic Claim

The source writes the cancellation expression as B0+A0=BA0+(−A0)=B0; this records the source notation without endorsing the entire equality chain.

  • Mapping Status: COMPLETE

③ Semantic Frame

  "context_nodes": [],
  "entity": {
    "id": "04_knowledge_base/Echo cancellation",
    "label": "Echo cancellation"
  },
  "frame_type": "ATTRIBUTE",
  "qualifiers": {

  },
  "value": {

    "value_text": "B0+A0=BA0+(−A0)=B0"

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

The source writes the cancellation expression as B0+A0=BA0+(−A0)=B0; this records the source notation without endorsing the entire equality chain.

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。
