    - Phase 54 manual sample candidate queue transaction：新增 `/api/market_intel/manual_sample_review/candidate_queue_transaction` POST 與 UI transaction preview 按鈕，將 queue row preview 轉成 `market_alert_review_queue` idempotent insert statement、payload hash 與 rollback plan；不開 DB connection、不開 transaction、不 commit、不建立 approval record；版本同步至 V10.227。
    - V10.228 補 PPT 視覺 QA 背景狀態卡：新增 `/observability/ppt_audit/vision_status` 與頁面 Vision QA 狀態卡，讓立即視覺 QA 排入後可看 queued/running/completed/error 與最近審核摘要，不必刷新猜測。
    - V10.229 修正 PPT 視覺 QA 多 worker 狀態漂移：將 queued/running/completed/error 寫入 `/app/data/ppt_vision_audit_status.json` runtime state，所有 Gunicorn worker 共用同一份狀態並阻擋重複排入。
+   - Phase 55 candidate queue writer CLI gate：新增 `/api/market_intel/manual_sample_review/candidate_queue_writer_status` POST、`scripts/market_intel_candidate_queue_writer.py` 與 UI writer gate 按鈕，定義 `MARKET_INTEL_QUEUE_WRITE_APPROVAL` 一次性 token、execute/apply flags、備份、migration smoke 與 rollback gate；本階段仍不開 DB connection、不寫 `market_alert_review_queue`、不 commit、不掛 scheduler；版本同步至 V10.230。
    - Schema smoke：`tests/test_market_intel_skeleton.py` 檢查 `Base.metadata` 內含 ADR-035 八張 `market_*` tables。
    - Desktop UI QA：本機只註冊 `market_intel_bp` 的 Flask harness 載入 `/market_intel`，確認 Phase 15、候選預覽、writer preview、安全 flags、點陣暖紙視覺正常，console error 0。
    - API QA：`/api/market_intel/schema_smoke` 通過 7 張表與 `market_platforms` 必要欄位檢查；`/api/market_intel/platform_seed_writer_plan` 回傳 4 筆 dry-run upsert preview，`writes_executed=false`，四平台皆 `blocked_dry_run_only`。
