 **完成（本地）**：
 
 - 新增 `ai_agent_critic_reviewer_result_capture_v1` schema、committed snapshot 與 backend loader，固定 5 張 Agent scorecard、5 個 result capture contract、6 個 promotion gate 與 4 條 candidate route。
+- Loader 新增可見文案紅線防退化檢查，snapshot 若再出現 `工作視窗`、`對話內容`、`批准！繼續`、`In app browser`、`My request for Codex` 或舊英文內部逐字稿詞，API 會 fail closed。
 - 新增 `GET /api/v1/agents/agent-critic-reviewer-result-capture` 只讀 API 與測試；API 只回傳 scorecard、result capture contract、promotion gate、candidate route 與 redaction boundary。
 - 治理頁 `/zh-TW/governance?tab=automation-inventory` 新增 P2-105 區塊，顯示 OpenClaw Critic / Reviewer、Hermes redaction / operator report、NemoTron failure verifier 如何互判、接手與阻擋 unsafe promotion。
 - 更新 `AI_AGENT_AUTOMATION_WORKLIST_2026-06-04.md`、`AI_AGENT_INTERACTION_LEARNING_PROOF_2026-06-11.md` 與 MASTER §3.2 / §5，將 P2-105 標記為完成，下一步改為 `P2-106` owner-approved result capture dry-run。
