    - V10.220 補 Phase 50 UI POST CSRF header：`manual_sample_review/evaluate` 保持 CSRF 保護，頁面 fetch 送出 `X-CSRFToken`，不豁免安全檢查。
    - Phase 51 manual sample candidate handoff：新增 `/api/market_intel/manual_sample_review/candidate_handoff` POST 與 UI handoff 按鈕，將已通過審核的 sample result 轉成只讀候選活動 preview payload；不保存 handoff、不建立 review queue、不寫 market_*、不允許候選導入、不掛 scheduler；版本同步至 V10.222。
    - Phase 52 manual sample candidate queue draft：新增 `services/market_intel/manual_sample_candidate_queue.py`、`/api/market_intel/manual_sample_review/candidate_queue_draft` POST 與 UI queue 草案按鈕，將 handoff 候選轉成只讀人工審核 queue draft；不建立正式 queue、不保存草案、不寫 market_*、不自動核准候選、不掛 scheduler；版本同步至 V10.223。
+   - V10.224 補 PPT 報表覆蓋矩陣：`/observability/ppt_audit_history` 將每個定義簡報同列串起 DB 寫入、線上預覽、視覺 QA 與交付狀態，並提供預覽、預熱、重跑操作，避免只顯示「目標已產生」。
    - 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`。
