# PChome Mapping Backlog Read-Only Report (2026-06-28)

正式環境目前以 `/api/ai/pchome-growth/opportunities` 作為 PChome 業績成長作戰清單來源。接續商品對應率優化時，先用只讀 reporter 取得 mapping backlog，不直接碰正式 DB。

## 產品優先順序

1. 先守住正式版本真相：production `/health` 必須是最新版本來源，本機只當 source candidate。
2. AI 自動化營收閉環優先：正式 `needs_mapping_count=16` 先處理 direct mapping，再處理 review candidate，不退回人工逐筆找商品。
3. AI Agent 決策必須 machine-verifiable：每個候選、證據補齊、單位價判斷、待確認項都要有 confidence、guardrails、trace、資料品質與可回滾下一步。
4. 主流專業產品網站化必須同步推進：首頁 / Dashboard 要直接呈現缺口、價值、下一步與可執行 package，不得只顯示工程 API 或 raw endpoint。
5. 外部來源治理要跟上：MOMO 是已接入來源，其他主流平台至少要有來源契約或待接入狀態；所有資料要正規化成 offer evidence。
6. 再做小批次 no-write operator package / persistence dry-run / verifier，確認可回滾、可重跑、可讀回。
7. 最後才推 DB apply authorization / signing / closeout 鏈；這些是底層 apply 安全工程，不得搶在產品缺口、AI 自動化與專業網站化前面。

- Dashboard no-write UI 已顯示 `auto_receipt_count` 與 `manual_review_required_count`，首頁不觸發外站 GET、不 persistence。
- production-derived evidence/source preview 目前 `task_count=6`、`tasks_with_blockers=6`、`missing_field_counts=image=6, availability=6, price=1, unit_price_or_package_basis=0`、`fetch_gate_candidate_count=6`；price 缺口樣本是 review candidate `DDABN0-A900IH795-000`。
- AI automation 只先產生 Ollama-first read-only assist plan；preview 不呼叫 LLM、不允許 Gemini、不寫 DB。
- 不執行 backfill POST。
- 不寫 DB、不掛 scheduler、不派 Telegram。
- 若版本 guard blocked，不應宣稱本地或 Gitea 是最新正式版本。

## 下一步

1. 進入 future DB apply authorization signing-issuer closeout / final signable request package：只收斂 signing issuer guard 的 signable boundary、source chain、same-run production truth、post-apply verifier、secret rejection 與 no-signing/no-write guarantees；仍不讀 secret、不在此步簽發 database apply authorization，也不直接 DB apply。
2. 以 Google Product / Merchant listing structured data 的 `Product.image`、`Offer.availability` 為解析目標。
3. 順手追 review candidate price payload 邊界，確認缺口是來源 payload 欄位缺失還是 summary 映射缺失。
4. image / availability / price payload 邊界都補齊並通過 production readback 後，才進入 operator write approval / backfill POST 小批次。
