    - Phase 67 candidate queue review decision approval：新增 `services/market_intel/candidate_queue_review_decision_approval.py`、POST `/api/market_intel/manual_sample_review/candidate_queue_review_decision_approval` 與 UI approval gate 按鈕，檢查人工決策草案是否可進入下一個 CLI-only transaction preview；API/UI 不更新 review_state、不寫 decision record、不建立 approval record、不讀 token、不掛 scheduler；版本同步至 V10.255。
    - Phase 68 candidate queue review decision transaction：新增 `services/market_intel/candidate_queue_review_decision_transaction.py`、POST `/api/market_intel/manual_sample_review/candidate_queue_review_decision_transaction` 與 UI transaction preview 按鈕，將 approval update preview 轉成 `review_state` update statement、payload hash 與 rollback plan；API/UI 不更新 review_state、不開 DB connection、不執行 CLI、不讀 token、不掛 scheduler；版本同步至 V10.256。
    - Phase 69 candidate queue review decision writer CLI gate：新增 `services/market_intel/candidate_queue_review_decision_writer_cli.py`、`scripts/market_intel_review_decision_writer.py`、POST `/api/market_intel/manual_sample_review/candidate_queue_review_decision_writer_status` 與 UI writer gate 按鈕，先建立 shell-only review_state writer gate 與 command bundle；writer implementation 本階段保持 disabled，API/UI 不讀 token、不執行 CLI、不連 DB、不更新 review_state、不掛 scheduler；版本同步至 V10.257。
+   - Phase 70 candidate queue review decision writer preflight：新增 `services/market_intel/candidate_queue_review_decision_writer_preflight.py`、POST `/api/market_intel/manual_sample_review/candidate_queue_review_decision_writer_preflight` 與 UI preflight 按鈕，檢查 writer status、review_state update payload、狀態轉換與禁止 token 進 API；API/UI 即使收到 execute/apply_real_write 也不連 DB、不執行 CLI、不更新 review_state、不 commit、不讀 token、不掛 scheduler；版本同步至 V10.258。
+   - V10.259 補 Phase 70 preflight 合約與 OCLearn queue 時區：preflight 補 planned/read-only catalog probe 欄位、dedupe unique index 檢查與 route 重複註冊清理；OCLearn embedding queue 的 created_at/updated_at/stale cutoff 改為台北 naive，避免 UTC/台北時間差讓 processing 任務卡住。
    - V10.248 補市場情報 390px preview panel QA：sample review 工具列改為 textarea + 可換行 action rail，移除舊的硬編 8 欄 grid；`check_responsive_overflow` 新增 `--screenshot-all`，本機 390x844 `/market_intel` 真頁面 QA 通過且 overflow=0。
    - V10.250 補 Code Review Gemini 備援遙測護欄：Ollama 主路徑失敗時 `fallback_to` 明確指向 `code_review_openclaw_gemini`，測試鎖住「Gemini 不得記成 `code_review_openclaw` 主 caller」；AI Calls 觀測台會把 legacy `code_review_openclaw + gemini` 顯示成 Gemini 備援，避免誤判 Gemini-first。
    - Schema smoke：`tests/test_market_intel_skeleton.py` 檢查 `Base.metadata` 內含 ADR-035 八張 `market_*` tables。
