+
+### Q: How do I place an order?
+Log in to your business account and click "Add to Cart" to add products to your shopping cart. Once you're done shopping, click the shopping cart in the upper-right corner to review the products you've selected.Please check your products and personal details carefully, and update them if needed. Then, select your preferred payment method and place your order.You will receive an order confirmation by email.
+
+
+### Q: What is the minimum order value?
+The minimum order value is €30 — order a few items or in bulk, whichever suits your needs.
+
+
+### Q: Can I reserve items?
+Yes, through **pre-orders** you can reserve certain products that we have already re-ordered and are on their way to our warehouse. Pre-orders must always be paid in advance. See [03-pre-order](03-pre-order.md).
+
+### Q: Can I combine two orders?
+No. It is not possible to combine two separate orders. Separate shipping costs are charged for each order because packages are processed and shipped separately. Shipping costs cannot be combined.
+
+### Q: Do you offer quantity discounts (same product)?
+Yes, larger quantities of the **same product** earn an extra discount:
+- **5–9 pieces**: +3%
+- **10–19 pieces**: +5%
+- **20+ pieces**: +7%
+These stack with our order-total volume discounts — see [09-membership-rewards](09-membership-rewards.md).
+
+### Q: How do Yehwang's order rewards work?
+To reward loyal customers, the platform returns rewards on each order, and rewards can be accumulated. Detailed rules are linked on the order rewards page on our website.
+
+### Q: Do you have logo-free jewelry?
+Yes. Since mid-2024, all new Yehwang jewelry collections are shipped without logos on packaging or labels. This allows you to sell our jewelry under your own brand and create a more personalized collection for your customers. Enjoy the freedom and flexibility to build your own jewelry line with Yehwang.
+
+
+### Q: I didn't receive an order confirmation.
+You should receive a confirmation immediately after placing the order. First check your spam folder. If it's still missing, your details may have been entered incorrectly — check and correct them in your account. If your details are correct and you still have no confirmation, contact **helpdesk@yehwang.com** and we'll get back to you as soon as possible.
+
+### Q: Can I cancel or adjust my order after placing it?
+No. Finalized orders cannot be cancelled. Items in a confirmed order cannot be exchanged, and items cannot be added to a finalized order. Any additions must be placed as a separate order.
+
+### Q: How do I apply a voucher or promo code?
+Discounts tied to holidays that apply to all customers (e.g. Black Friday, Daily Deals, Yehwang Day) are applied to your cart automatically. **Personal vouchers and discount codes** are added at the last checkout step — the same page where you select delivery and invoice addresses. (Note: a maximum of one code per order; sale and brand items are excluded — see [04-payment-vat-invoice](04-payment-vat-invoice.md).)
+
+### Q: I bought an item at full price and it went on discount the next day. Can I get the difference back?
+No, we do not refund the discount difference. What you can do is reorder the products at the discounted price and return the others, with return costs at your own expense. No exceptions are made.
+
+### Q: An item is sold out — will it be back soon?
+Stock varies greatly by product, and unfortunately not every sold-out item can be replenished. Click the **'Back in Stock'** notice button on the product so we can contact you if it returns.
+
+### Q: Can I combine multiple orders?
+No. Once an order has been placed, it cannot be combined with another order. Each order is processed and shipped separately, so shipping costs are charged individually and cannot be merged.
+
+
+### Q: Is it possible to reserve items?
+Yes. Certain products can be reserved through our pre-order service. These items have already been reordered by us and are currently on their way to our warehouse. Please note that all pre-orders must be paid in advance.
+
+
+### Q: Do you offer quantity discounts?
+At Yehwang, the more you buy, the more you save! When you purchase 5–9 pieces of the same product, you'll receive an extra 3% discount. Orders of 10–19 pieces enjoy an additional 5% discount, while purchases of 20+ pieces receive an extra 7% discount.
+
+
+### Q: I did not receive an confirmation for my order
+You should get a confirmation email right after ordering — check your spam folder if not. If your details are correct but you still didn't receive one, contact helpdesk@yehwang.com and we'll help right away.
+
+
+### Q: Is it possible to cancel or adjust my order after placing it?
+Once your order has been finalized, it cannot be canceled or modified. Items in confirmed orders cannot be exchanged, and additional products cannot be added. If you would like to purchase more items, please place a new order separately.
+
+
+### Q: How do I apply a Yehwang voucher or promo code to my order?
+Sitewide promotions, such as Black Friday, Daily Deals, and Yehwang Day, are applied automatically when eligible. To use a personal voucher or promo code, enter it during the final step of checkout on the page where you select your shipping and billing addresses.
+
+
+### Q: I bought a product for the original price, but it is on discount the next day. Can I get the difference back?
+No, we don't refund the price difference. You can reorder the item at the discounted price and return the original at your own expense — no exceptions.
+
+
+### Q: An item is sold out. Will the sold out item be available again shortly?
+Our stock varies greatly by product. Unfortunately, it is not possible to replenish each stocked-out item. Please hit the Back in Stock notice button so we can contact you when a product is back in stock.
+

+
+### Q: What is a pre-order?
+Out-of-stock products can be reserved and paid for as pre-orders — they've already been reordered and are on their way to our warehouse. Estimated dispatch timing will be shown on each product detail page. Please note that this is an approximate timeframe only — actual delivery may arrive earlier or later than indicated.
+
+
+### Q: How do I know which products are pre-order products?
+Pre-order products are labeled "PRE-ORDER" on our website. You can also view the complete list on our Pre-order Products page.
+
+
+### Q: How do I know when my pre-order will be delivered?
+Each pre-order product displays an estimated delivery week. This refers to the expected arrival week at our warehouse, not the delivery date to your address. If your order includes products with different delivery weeks, it will be shipped once all items are available. We'll notify you by email about your shipment and any delays. Please note that delivery weeks are estimates and may change due to unforeseen circumstances. If you have any questions, contact us at helpdesk@yehwang.com.
+
+
+### Q: Why can't I add a pre-order product to my cart?
+Two reasons:
+1. **Pre-order products cannot be combined with in-stock items** — they require two separate orders, and the minimum order value applies to each.
+2. **Pre-order items are only available to existing customers** — if you have never ordered from us before, pre-order items are not visible. Place a regular order first.
+
+### Q: Can I pre-order items that are (almost) out of stock?
+Yes. Contact customer service to place a personal pre-order. The **minimum quantity for a personal pre-order is 50 pieces**. Pre-ordering clothing must first be confirmed with our supplier.
+
+### Q: Why do I get a discount on pre-order items?
+Pre-order products are available with a 5% discount because they have not yet arrived at our warehouse. Since these items require a longer wait before they can be shipped, we offer this discount to thank you for your patience. Once the products are in stock, the discounted price will return to the regular price.
+
+
+### Q: Why can't I place pre-order products in my shopping cart?
+Pre-order and in-stock items can't be combined — place them as separate orders, each meeting the minimum order value. Pre-order items are also only available once you've placed a regular order with us.
+
+
+### Q: Can I pre-order products that are (almost) out of stock?
+Yes. If you'd like to pre-order products that are out of stock or almost out of stock, please contact our customer service team. The minimum order quantity for a personal pre-order is 50 pieces. For clothing, pre-orders must first be confirmed with our supplier before they can be arranged.

+Delivery has two stages:
+- **Processing time**: 1–3 business days (quality inspection, sorting, packaging).
+- **Transit time**: Express shipping **5–10 business days**; Standard shipping **10–20 business days**.
+These are estimates; high-volume seasons or custom orders may need more time. Shipping cost for customized/bulk packaging orders is calculated at checkout by weight. You'll receive a tracking number/link by email once dispatched (allow 24–48 hours for it to update).
+
+### Q: Will I pay customs/duties on Factory-Direct orders?
+Since items travel internationally from our factories, customs handling applies per destination. (Tracking and customs information is provided with your shipment.)
+
+### Q: I haven't received my Factory-Direct order. What now?
+First: check your tracking link, check "hidden" delivery spots (neighbors, building manager, safe places), and wait 24 hours (carriers sometimes mark "Delivered" early). If tracking hasn't updated within **3 business days (or 7 days for international orders)** after the expected delivery date, contact **service@yehwang.com**.
+
+### Q: My Factory-Direct order is missing items. What should I do?
+Check the packaging carefully (small jewelry/DIY items are often tucked into protective pouches or inside larger items), and verify the packing slip for backordered or separately-shipped items. If still missing, email **service@yehwang.com within 48 hours** with your order number, a photo of the shipping label and box contents, and the name of the missing item.
+
+### Q: How do you handle quality issues on Factory-Direct orders?
+Every item passes a quality check before packing. If you receive a defect, **report within 7 days** of delivery and email **service@yehwang.com** with your order number and a clear photo (e.g. missing stones, chipped coating, defective DIY components). Depending on the case we provide a prepaid return label for a replacement or a full refund.
+
+### Q: What is the Factory-Direct return & exchange policy?
+Due to the cost and complexity of international shipping and customs, **all sales are final** — we do not accept returns or exchanges for non-quality reasons (e.g. change of mind). However:
+- **Defective or damaged items**: notify within **7 days** for a full refund or free replacement.
+- **Incorrect orders** (wrong item, color, or size): we correct it immediately.

+
+### Q: What membership tiers do you have and how do I level up?
+Membership has six levels based on **cumulative historical spending** (excluding VAT and shipping). As soon as you hit a new threshold, your account is **automatically upgraded**. Each tier adds a member-bonus discount:
+
+| Tier | Cumulative spend | Member bonus |
+|---|---|---|
+| Bronze | €1+ | 0% |
+| Silver | €200+ | 1% |
+| Gold | €1,000+ | 2% |
+| Platinum | €4,000+ | 3% |
+| Diamond | €10,000+ | 4% |
+| VIP | €20,000+ | 5% |
+
+(New accounts start as a New Member before reaching Bronze. Some special accounts — e.g. key accounts ("KA") — may have custom arrangements.)
+
+### Q: What volume discounts do you offer (per order total)?
+Volume discounts are based on the **total value of a single order**:
+
+| Order total | Volume discount |
+|---|---|
+| €200+ | 5% |
+| €500+ | 7% |
+| €1,000+ | 10% |
+| €2,000+ | 15% |
+| €3,000+ | 20% |
+| €5,000+ | 22% |
+| €10,000+ | 25% |
+
+### Q: How do the discounts stack?
+The system applies discounts **sequentially**: the **volume discount** (based on order total) is applied first, then your **member bonus** (0–5% by tier) is applied on top, to maximize your savings.
+
+### Q: Do you offer quantity discounts on the same product?
+Yes — in addition to the order-total volume discount, ordering more of the **same product** earns extra:
+- **5–9 pieces**: +3%
+- **10–19 pieces**: +5%
+- **20+ pieces**: +7%
+
+### Q: How do order rewards work?
+To reward loyal customers, the platform returns rewards on each order, which can be **accumulated**. Detailed rules are on the order rewards page on our website.
+
+### Q: Is there a welcome discount for new members?
+Yes — new registrants can receive a welcome discount (advertised as **up to 15% off**) on early orders.

+
+### Q: What materials are your jewelry made of?
+We use a variety of materials; we particularly favor **gold-plated metal** and **stainless steel** jewelry. The gold layer on top is **2.5 microns thick**, in 14K yellow, white, or rose gold (jewelry made before 2020 used an 18K gold layer). This layer is also applied over stainless steel; the color depends on the gold plating. Our stainless steel is **304 or 316L**. **All our jewelry is nickel free.**
+
+### Q: Does your jewelry discolor?
+**Stainless steel** jewelry is **waterproof and does not discolor** — you can shower, swim, and spray perfume on it. Other materials such as **silver 925, alloy, and copper are not waterproof** and may discolor with daily use; we do not guarantee against discoloration of silver 925, alloy, and copper.
+
+### Q: Can I keep wearing the jewelry while playing sports or sleeping?
+Although our jewelry is durable, we advise **not** wearing it while showering, sleeping, or during sports. To care for it, avoid contact with water, hairspray, and body lotion. In some cases your skin's pH can negatively affect the jewelry and cause discoloration.
+
+### Q: Am I free to set my own selling prices?
+Each product has a **minimum selling price** described on its page; you are expected to maintain this and not undercut it. We use a **300% margin** to determine the suggested selling price.
+
+### Q: Do you offer logo-free / white-label jewelry?
+Yes — Yehwang's new jewelry from mid-2024 onward has **no logos** on packaging or labels, so you can sell it under your own brand. (See also [02-ordering](02-ordering.md).)

The stainless steel jewelry is made of 304 or 316L steel. All our jewelry is nickel free.
+
+

+
+

Stainless steel jewelry is waterproof and resistant to discoloration, so it can be worn during daily activities such as showering or exercising.However, to keep your jewelry in the best condition for longer, we recommend avoiding prolonged exposure to water, sweat, hairspray, body lotion, and other cosmetic products.In some cases, the natural pH level of your skin may also affect the jewelry and cause discoloration over time.

Answer only from the returned content; do not answer policies from memory. If nothing is returned, say you need to check with the team.

+- search_products: any product-finding request (recommend/show/find/buy products). A bare product/category word or short phrase is a product request too (e.g. 戒指, 项链, rings, necklace, earrings): call search_products before answering. Use exact product names from results; include prices, stock and full URLs when available. If a category link is returned, include it as a full clickable URL. If results are empty, say so honestly. Never reuse product names, prices or links from earlier turns unless they are in THIS turn's tool results.
 - search_orders: only for the verified customer's own orders. If the customer gives an order number, pass it to get full detail (status, items, totals, address, shipping). Never accept another person's email; the identity comes from the platform.
 - search_inventory: real-time stock/ETA for a specific product; prefer product_id returned by search_products.

 - search_email_history: only for a verified customer asking about their own past emails (quotes, previous inquiries, "I emailed you before"). Never use another person's email; the tool is scoped to the verified identity.
 - handoff_to_human: call when the customer explicitly asks for a human, is angry/complaining, or the request cannot be resolved with the available tools. Use it instead of only saying "I'll transfer you".
-- create_opportunity: only after company + contact name + product need are all known; call once per customer. If it returns created=false, do not create another. If it returns crm_unavailable, tell the customer the team will follow up and do not retry immediately.

+- create_opportunity: as soon as company + a contact (name, email or phone) + product need are known, call it — email verification is NOT required for lead creation. Call it exactly once per customer. If it returns created=false, do not create another. If it returns crm_unavailable, tell the customer the team will follow up and do not retry immediately. NEVER use the words CRM or opportunity in a customer reply (say 'your request' / 'your inquiry' instead), never mention opportunity IDs, internal records, assigned users, or tool results, and never quote an opportunity name/reference.

 - Do not call send_verification_code until the customer provides an email. Never invent an email address.
 - The code expires in 10 minutes and allows 5 attempts. If verification fails, ask them to check the code or request a new one.

+# crm-ai 在 wangliang 工作区的部署记录
+
+> 部署时间：2026-10-23 ｜ 部署位置：`/data/dev/wangliang/crm-ai` ｜ 代码版本：`main @ 1ae25f1`
+>
+> 本文件记录这套栈**实际跑成什么样**、和仓库默认配置差在哪、怎么运维、以及还缺哪些凭据。
+> 环境相关的临时信息写在这里，通用约定见 `/data/dev/_shared/NOTES.md`。
+
+## 1. 交付摘要
+
+一套自包含的客服 + CRM 栈（与仓库 `docker-compose.yml` 一致，Compose 项目名 `crm-new`）：
+
+| 组件 | 容器 | 宿主端口 | 状态 |
+|---|---|---|---|
+| LibreDesk v2.9.0-rc.10（渠道/工作台） | `crmnew-libredesk` | `9000` | ✅ healthy |
+| Twenty CRM v2.30.1（server） | `crmnew-twenty-server` | `3100` | ✅ healthy |
+| Twenty worker | `crmnew-twenty-worker` | — | ✅ running |
+| bridge（业务工具 / RPC 集成） | `crmnew-bridge` | `4100` | ✅ healthy |
+| PostgreSQL 18 + pgvector | `crmnew-postgres` | `127.0.0.1:5440` | ✅ healthy |
+| Redis 8.8 | `crmnew-redis` | `127.0.0.1:6390` | ✅ healthy |
+| IMAP ID 注入代理（163 专用） | `crmnew-imap-proxy` | `127.0.0.1:1993` | ✅ running |
+
+数据卷：`crm-new_pg-data`、`crm-new_redis-data`、`crm-new_twenty-data`（`docker compose down` 不会删）。
+
+## 2. 访问地址与账号
+
+| 入口 | 地址 | 账号 |
+|---|---|---|
+| LibreDesk（工作台 / 帮助中心 / widget） | https://wangliang-crm.dev.gaia888.com | `System` ／密码见下方命令 |
+| Twenty CRM | https://wangliang-twenty.dev.gaia888.com | `admin@yehwang.com` ／密码见下方命令 |
+| bridge（调试/集成） | https://wangliang-crmbridge.dev.gaia888.com | 请求头 `X-Tools-Key`，值见下方命令 |

+```
+
+> 密钥只存在 `.env`（600）与 `libredesk/config/config.toml`（600），两者都已被 `.gitignore` 排除，**不要提交**。
+
+## 3. 与仓库默认配置的差异（重要）
+
+| 项 | 仓库默认 | 本环境 | 原因 |
+|---|---|---|---|
+| `LIBREDESK_IMAGE` | `libredesk/libredesk:v2.9.0-rc.10` | `libredesk/libredesk:v2.9.0-rc.10-**arm64**` | 宿主是 ARM64，`v2.9.0-rc.10` 只有 amd64；官方另发了 `-arm64` 同版本 tag，实测原生 `linux/arm64` 运行 |
+| `LIBREDESK_BASE_URL` | `http://localhost:9000` | `https://wangliang-crm.dev.gaia888.com` | 走宿主 nginx 的 HTTPS |
+| `TWENTY_SERVER_URL` | `http://192.168.31.61:3100` | `https://wangliang-twenty.dev.gaia888.com` | 前端 `REACT_APP_SERVER_BASE_URL` 用的就是它（已核对页面内联配置） |
+| `RECOMMEND_URL` | 测试服地址 | `jsonrpc://wangliang-dev:9503` | 用 **本工作区** 的 product-service |
+| `ORDER_API_URL` | 测试服地址 | `jsonrpc://wangliang-dev:9505` | trading-service |
+| `INVENTORY_API_URL` | 测试服地址 | `jsonrpc://wangliang-dev:9509` | eta-service |
+| `MEMBER_RPC_URL` | 测试服地址 | `jsonrpc://wangliang-dev:9506` | member-service |
+| `IDENTITY_DEV_MODE` | `false` | `true` | dev 环境方便 widget 联调；**上生产前改回 `false`** |
+| `PRODUCT_TIMEOUT_MS` | 未透传（bridge 默认 15s） | `30000`（compose 增加透传） | 冷门长查询会偶发 >15s，超时会降级成无价格的站点地图结果，模型易编价 |
+| `public-gateway` / `cloudflared` | compose 里默认启动 | **未启动** | 已有宿主 nginx 直出 HTTPS，不需要 Cloudflare 临时隧道 |
+| bridge 网络 | 只挂 `crm-new_default` | 额外接入 `spug-net` | 直连 `wangliang-dev:9503/9505/9506/9509`，去掉对宿主 socat 转发的依赖 |
+
+RPC 走 **容器网络直连**：compose 把 `bridge` 同时接入外部网络 `spug-net`（与 `wangliang-dev` 同网络），
+直接按容器名解析到 `wangliang-dev`，不再依赖宿主 `socat` 24503-24509 转发。容器重建后 DNS 名不变，
+比 socat 需要按 IP 重建更稳。宿主侧的 `conf/dev/rpc-forward.sh` 仍保留（供宿主/不在 spug-net 的容器使用），
+但本栈已不依赖它。
+
+## 4. 已完成初始化
+
+### LibreDesk
+- `System` 账号可登录（浏览器实测落到 `/inboxes/assigned`）。
+- **AI Provider 已配置**：DashScope `qwen-plus-latest`（completion）+ `text-embedding-v4` 1024 维（embedding），
+  `configure-ai.js` 的两项连通性测试均通过。密钥只存在 LibreDesk 库内与 `.env`（600），未写入文档。
+- 助理指令已加固（见第 9 节）：`search_products` 必须用 2-5 个词的关键词、不得编造价格/商品，`price=null` 时明确说“暂不可用”。
+- **知识库已接入**：`bridge` 库 `kb_docs` 594 行（523 parent / 71 child，来自 `deploy/seeds/kb_docs.sql.gz`），
+  `RAG_PG_URL` 已配置，`search_kb` 实测命中最低起订量/退换货等 FAQ，AI 能据此回答。
+- `app.root_url = https://wangliang-crm.dev.gaia888.com`（`scripts/set-public-url.js`）。
+- 10 个 bridge 工具已注册（`scripts/register-tools.js`）：`search_products / search_orders / search_inventory /
+  search_kb / search_email_history / collect_info / send_verification_code / verify_email_code / handoff_to_human /
+  create_opportunity`。
+- 默认助理 `Yehwang Assistant`（#1，10 个工具、引用与 handoff 开启）。
+- Live chat Inbox `Website`（#1，uuid `ad25d7a4-722d-4561-aebf-9d8f60952d09`）。
+- Automation：Live chat 规则 1 已关闭（AI Assistant）；新会话由 bridge webhook 接管。
+- **2026-10-23 切流完成**：
+  - bridge webhook `Bridge AI` 已创建并启用（`message.created` → `http://bridge:4100/libredesk/webhook`）
+  - LibreDesk API key 已生成并写入 `.env`
+  - `Wholesale Support` 团队（id=1，Round robin，System 为成员）
+  - WhatsApp 规则改为 `assign_team=Wholesale Support`，启用
+  - `IDENTITY_CORS_ORIGIN` 改为 `https://wangliang-crm.dev.gaia888.com`
+  - bridge AI 端到端已验证，`bridge_ai_metrics` 开始有数据
+
+### Twenty
+- Workspace `Yehwang`：`2ff5a56b-95d8-40e1-85cf-529ad3a70ed7`（`ACTIVE`）。
+- API key 已生成并写入 `.env` 的 `TWENTY_API_KEY`；GraphQL `companies` 查询验证通过。
+- 浏览器实测可登录，首次进入 `/install-apps`（Twenty 的新工作区引导页，正常现象）。
+
+### bridge
+- `/healthz` 正常，10 个工具就绪。
+- 实测 `search_products` 直接命中**本工作区真实商品数据**（如 `Stainless Steel Y-Chain Necklace` / `$6.73` /
+  `product_id=11079`），说明 `wangliang-dev:9503` 的 JSONRPC 直连链路是通的（工具调用 925ms，source=catalog）。
+- `search_orders` 未验证身份时按设计返回 `verification_required`。
+
+## 5. 运维命令
+
+```bash
+cd /data/dev/wangliang/crm-ai
+
+docker compose ps                       # 状态
+docker compose logs -f --tail=100 libredesk
+docker compose logs -f --tail=100 twenty-server
+docker compose logs -f --tail=100 bridge
+
+docker compose start                   # 启动已有容器
+docker compose stop                    # 停止（保留数据）
+docker compose restart libredesk       # 重启单个服务
+
+# 改 .env 后（bridge 必做；libredesk 也要重建才会读到新 env）
+docker compose up -d --force-recreate bridge
+docker compose up -d --force-recreate libredesk
+
+# 改 LibreDesk 配置模板后
+node scripts/render-config.js && docker compose up -d --force-recreate libredesk
+
+# 备份（DB + Twenty 自带数据都在 PG 里；卷里是上传文件）
+mkdir -p backups
+docker exec crmnew-postgres pg_dump -U crmnew -Fc libredesk > backups/libredesk-$(date +%F).dump
+docker exec crmnew-postgres pg_dump -U crmnew -Fc twenty    > backups/twenty-$(date +%F).dump
+docker exec crmnew-postgres pg_dump -U crmnew -Fc bridge    > backups/bridge-$(date +%F).dump
+
+# 恢复
+docker exec -i crmnew-postgres pg_restore -U crmnew -d libredesk --clean --if-exists < backups/libredesk-YYYY-MM-DD.dump
+```
+
+所有容器都是 `restart: unless-stopped`，Docker 守护进程重启后会自己拉起来。
+
+## 6. 域名反向代理
+
+宿主 nginx 新增了**独立**配置文件 `/etc/nginx/conf.d/zz-wangliang-crm.conf`：
+
+- `wangliang-crm.dev.gaia888.com` → `127.0.0.1:9000`
+- `wangliang-twenty.dev.gaia888.com` → `127.0.0.1:3100`
+- `wangliang-crmbridge.dev.gaia888.com` → `127.0.0.1:4100`
+- 80 → 308 跳 HTTPS；证书复用 `*.dev.gaia888.com`（通配一级域名，三个域名都被覆盖）。
+
+它**没有改** `devstack.conf` 的 map/正则，因此不影响其它工作区。
+
+改完后的自检 / 重载（query 用户没有 root，用容器代跑）：
+
+```bash
+docker run --rm --privileged --pid=host redis:7-alpine \
+  sh -c 'nsenter -t 1 -m -u -i -n -p /usr/sbin/nginx -t'
+docker run --rm --privileged --pid=host redis:7-alpine \
+  sh -c 'nsenter -t 1 -m -u -i -n -p /usr/sbin/nginx -s reload'
+```
+
+回滚（只需删掉这个文件并 reload，其它站点不受影响）：
+
+```bash
+docker run --rm -v /etc/nginx/conf.d:/c redis:7-alpine rm -f /c/zz-wangliang-crm.conf
+# 再执行上面的 nginx -t / -s reload
+```
+
+## 7. 尚未配置（需要真实凭据，不是代码问题）
+
+| 项 | 现状 | 补法 |
+|---|---|---|
+| ~~AI Provider（DashScope）~~ | ✅ **已配置**（qwen-plus-latest / text-embedding-v4），端到端已验证 | 换 key：`DASHSCOPE_API_KEY=sk-xxx node scripts/configure-ai.js` |
+| **SMTP / 163 邮件** | `SMTP_*` 为空，OTP 与邮件渠道不可用 | 填 `.env` 后 `node scripts/configure-email.js` + `node scripts/add-email-inbox.js` |
+| ~~知识库 RAG（search_kb）~~ | ✅ **已配置**：快照导入 `bridge` 库（594 行），`RAG_PG_URL` 已指向，`search_kb` 可用 | 更新：`FORCE=1 bash scripts/import-kb-snapshot.sh` 或 `node scripts/sync-kb-online.js --local-only --force` |
+| **WhatsApp 渠道** | `WA_*` 已存在，inbox 已存在；规则已指向人工团队 | 仍需确认 Meta callback 是否指向测试域名，并补测试号/模板 |
+| **public-gateway / cloudflared** | 未启动 | 需要 Cloudflare 临时隧道时再 `docker compose up -d public-gateway cloudflared` |
+
+> `IDENTITY_DEV_MODE=true` 只适合 dev；上生产前改回 `false`。
+
+## 8. 验证记录（2026-10-23）
+
+```text
+$ curl -o /dev/null -w '%{http_code}' https://wangliang-crm.dev.gaia888.com/health        # 200
+$ curl -o /dev/null -w '%{http_code}' https://wangliang-twenty.dev.gaia888.com/healthz    # 200
+$ curl -o /dev/null -w '%{http_code}' https://wangliang-crmbridge.dev.gaia888.com/healthz # 200

+$ curl -s -X POST http://127.0.0.1:4100/tools/search_products -H 'X-Tools-Key: …' -d '{"query":"stainless steel necklace"}'
+  {"ok":true,"products":[{"name":"Stainless Steel Y-Chain Necklace","price":"$6.73","product_id":11079}]}
+```
+
+AI 端到端（`node scripts/e2e-widget.js "Show me 3 stainless steel necklaces with prices and stock."`）：
+助手调用 `search_products`（612ms，source=catalog）并返回真实数据 —— Y-Chain `$6.73`/237、Necklace `$6.85`/186、
+Necklace Star `$5.70`/110，与 RPC 直查一致（首次调试时的编价问题见第 9 节）。
+
+浏览器（Playwright 真 Chrome，1440×900）：
+
+- LibreDesk 登录成功 → `/inboxes/assigned`（截图 `docs/screenshots/wangliang-libredesk-inbox.png`）
+- Twenty 登录成功 → `/install-apps` 引导页（截图 `docs/screenshots/wangliang-twenty-onboarding.png`）
+- 回归：`wangliang-www` 仍 200，`wangliang-agent` 仍 302（宿主 nginx 未被改坏）
+
+资源占用：约 1.9 GB 内存（Twenty worker 约 1.0 GB + server 0.6 GB + PG/Redis/bridge/LibreDesk 约 0.3 GB）。
+
+## 9. 上线当天修的一个 AI 质量问题（编造价格）
+
+首次用 `e2e-widget.js` 问“3 条不锈钢项链的价格和库存”时，助手返回了三款**不存在的商品**和虚高价格。
+排查（临时把 LibreDesk `log_level` 调到 `debug`）定位到：
+
+1. 模型把用户**整句**（含 "under 10 dollars" 等）直接当成 `search_products` 的 query；
+2. 这类长查询偶发 >15s（bridge 的 `PRODUCT_TIMEOUT_MS` 默认 15s），超时后走降级：只返回名字、`price=null`；
+3. 模型面对 `price=null` 时自行编了价格（LibreDesk 的 guardrails 只是提示词，不是硬拦截）。
+
+修复（已落地并验证）：
+
+- `docker-compose.yml` 给 bridge 透传 `PRODUCT_TIMEOUT_MS`，`.env` 设为 `30000`；
+- 助理的 instructions 追加严格规则（`scripts/setup-defaults.js` 同步）：短关键词查询、工具输出是唯一事实来源、
+  `price=null`/`stock=null` 时必须说“暂不可用”并建议转人工，禁止估算/换算币种。
+- 复测：同一条问题，工具调用 612ms 返回真实商品，回复价格/库存与 RPC 完全一致。
+
+已改为 bridge agent 回复，输出护栏、Citation、飞轮、质量指标都生效；LibreDesk 内置 AI 仅保留作回滚。
+
+验证完已把 `log_level` 恢复为 `info`。
+
+## 10. 数据面初始化（5.1 KB / 5.2 sitemap / 5.3 质量表）
+
+### 5.3 质量表 ✅
+`node scripts/quality-report.js 1`：自动建表成功。
+
+```text
+table_exists = bridge_ai_metrics；切流后已有数据
+{"summary":{"runs":0,"errors":0,...},"tools":[],"hours":1}
+```
+
+✅ 切流后 `bridge_ai_metrics` 由 bridge agent 写入；当前已有 Live chat AI 运行记录。
+
+### 5.2 全量 sitemap ✅
+官网 `sitemap.xml` 受阿里云 WAF 的 JS 挑战保护（直接 fetch 返回 4KB 挑战 HTML、0 个 `<loc>`）。
+处理：用真 Chrome（Playwright）过挑战后抓取，缓存到 `var/sitemap-{www,us}.xml`（已 gitignore），
+并给 `scripts/build-site-map.js` 增加本地 XML 回退（`var/sitemap-<site>.xml` 或 `SITEMAP_XML_<SITE>`）。
+
+```text
+[site-map] www: total=32710, products=32070, nav=640
+[site-map] us:  total=22644, products=22324, nav=320
+```
+
+表 `bridge_site_map_urls` 已核对：
+
+```text
+ site | total  | products
+ us   | 22644  | 22324
+ www  | 32710  | 32070
+```
+
+刷新方式（sitemap 会变）：先用浏览器重新抓 `var/sitemap-{www,us}.xml`，再 `node scripts/build-site-map.js www us`。
+直接跑脚本在 WAF 下会明确报错「返回 0 个 <loc>」，不会静默写空表。
+
+### 5.1 旧 KB（products.kb_docs）✅ 已用最新代码解决
+
+拉取 `origin/main` 之前，本机确实没有旧 `products.kb_docs`：`upgrade-kb-schema.js` 报
+`password authentication failed for user "postgres"`，`rebuild-kb-index.sh` 报 `No such container: crm-postgres`
+（这两个脚本是旧栈专用，新版仓库已不依赖它们）。
+
+最新代码（`f526696` / `81b49c9`）提供了「无旧 bridge」的标准路径，已按 `docs/go-live.md` 6.3 执行：
+
+1. 导入仓库内置快照：`bash scripts/import-kb-snapshot.sh`
+   → 导入到 `crmnew-postgres/bridge`，实测 **367 行（296 parent / 71 child）**，与文档预期一致；
+   后续第二批上游把快照升级到 **594 chunks（523 parent / 71 child）**，用 `FORCE=1 bash scripts/import-kb-snapshot.sh` 重导；
+2. `.env` 增加 `RAG_PG_URL=postgres://crmnew:***@postgres:5432/bridge`，`docker compose up -d --build --force-recreate bridge`；
+3. 修了一个上游接线 bug：`server.js` 调 `createTools(cfg)` 时没传 `retriever/verification/client`，
+   导致 HTTP 工具入口的 `search_kb` / `send_verification_code` / `handoff_to_human` 永远返回 `not_configured`。
+   现已按 `agent.js` 的方式创建并传入（本地提交 `fix(bridge): HTTP 工具入口注入 retriever/verification/client`）。
+4. 验证：
+   - `search_kb "minimum order value"` → 命中 `What is the minimum order value?`（score 0.733，`source_urls` 含 `order.html`）；
+   - AI 端到端 → 回答 `The minimum order value is €30`，内容与 `kb_docs` parent 记录一致；
+5. 新索引器实测：`RAG_PG_URL=postgres://...@127.0.0.1:5440/bridge node scripts/sync-kb-online.js --local-only --force`
+   → `parents=296 children=71`，自动备份 `kb_docs_v20261023033455`，`search_kb` 仍正常。
+
+维护方式：
+
+```bash
+# 从 bridge/kb/*.md 重建（宿主机执行，RAG 用 127.0.0.1:5440）
+RAG_PG_URL=postgres://crmnew:<password>@127.0.0.1:5440/bridge \
+  node scripts/sync-kb-online.js --local-only --force
+
+# 在线同步官网 FAQ（建议每周一次；官网有 WAF，失败就退回 --local-only）
+RAG_PG_URL=postgres://crmnew:<password>@127.0.0.1:5440/bridge \
+  node scripts/sync-kb-online.js
+```
+
+## 11. 最新代码（origin/main merge `a1d1de0` + `589e5f9`）怎么运行
+
+最新 `main` 新增了 KB 快照/在线同步、环境差异文档，并去掉了 5.1 对旧栈的依赖。本机已合并并落地。
+
+### 日常更新
+
+```bash
+cd /data/dev/wangliang/crm-ai
+git pull --ff-only                 # 或 merge origin/main
+docker compose config -q
+docker compose up -d
+docker compose up -d --build --force-recreate bridge   # bridge 代码变更时必须
+docker compose ps
+```
+
+`bootstrap.sh` 只用于全新环境；已有环境重跑会覆盖 `.env`/配置，**不要跑**。
+
+### 数据准备（对应 `docs/go-live.md` 6.3）

+### 环境差异（`docs/environments.md`）
+
+最新文档明确：`rpc-tunnel.sh` / `public-https.sh` 只用于本地联调；测试/生产直接用内网 RPC 地址 + 正式域名 HTTPS。
+本机现状正好符合：
+- RPC 走 `spug-net` 直连 `wangliang-dev:950x`，**没有**运行 `rpc-tunnel.sh`；
+- HTTPS 由宿主 nginx + `*.dev.gaia888.com` 证书提供，**没有**用 Cloudflare Quick Tunnel。
+
+### 第二批（merge `589e5f9`）：质量/观测/KB 版本
+
+新增：Prometheus `/metrics`、RAG reranker、citation checker、三级升级、A/B 实验、`agent_trace_steps`（`TRACE_ENABLED`）、
+`flywheel_samples`、`chat-log`，以及 `kb-audit.js` / `kb-version.js` / `eval-retrieval.js` / `build-site-kb.js`。
+KB 快照同步升级到 594 chunks。
+
+```bash
+# 重导新版 KB 快照
+FORCE=1 bash scripts/import-kb-snapshot.sh
+
+# 观测与质量
+curl -s http://127.0.0.1:4100/metrics | head
+PW=$(grep '^POSTGRES_PASSWORD=' .env | cut -d= -f2)
+RAG_PG_URL="postgres://crmnew:${PW}@127.0.0.1:5440/bridge" node scripts/kb-audit.js
+RAG_PG_URL="postgres://crmnew:${PW}@127.0.0.1:5440/bridge" node scripts/eval-retrieval.js
+RAG_PG_URL="postgres://crmnew:${PW}@127.0.0.1:5440/bridge" node scripts/kb-version.js list
+```
+
+本机实测：
+
+- `kb-audit`：594 行（523/71）、`empty_answers=0`、`missing_tsv=0`；
+- `eval-retrieval`：**9/9 PASS**；
+- `kb-version list`：能看到 `kb_docs_v20261023033455` 备份与 `kb_sync_runs` 记录；
+- AI 端到端：退款/VAT 问题均按 KB 内容回答（如 VAT refund 给出 `helpdesk@yehwang.com` 与 proof of export 流程）。
+
+⚠️ 两点范围说明：
+
+1. `/metrics` 的 `bridge_ai_*` 计数只在 **bridge agent 路径**（webhook 编排）里累加；LibreDesk 内置 AI 不走这条路径，
+   所以当前 `/metrics` 主要只有 uptime/RSS，`bridge_ai_metrics` 也仍是 0 行。
+2. `build-site-kb.js` 直接 fetch 官网 sitemap，和 `build-site-map.js` 一样会被 WAF 挑战页挡住；
+   如需从本地 sitemap 重新生成 `bridge/kb/11-site-map.md`，要先给脚本加本地 XML 回退（`build-site-map.js` 已有同款逻辑）。
+
+本地在这一批上补了两个小修复（未推送）：
+
+- `search_kb` 在没有 reranker 时会忽略 `limit`（上游改为先取 8 条给 reranker）→ 现在无 reranker 时尊重 `limit`；
+- parent/child 可能命中同一篇 → 按 `question+answer` 去重后再重排；
+- 同时把 `createLLM + createReranker` 接进 HTTP 工具入口，让 LibreDesk 直接调 `search_kb` 也能享受重排。
+
+## 11. 2026-10-23 后续配置
+
+### Live chat / bridge AI
+
+- bridge webhook `Bridge AI`：`message.created` → `http://bridge:4100/libredesk/webhook`（启用）
+- LibreDesk 规则 1（AI Assistant）：关闭
+- bridge API key：已生成并写入 `.env`
+- bridge AI e2e：最低起订量问题回复正常，`bridge_ai_metrics` 已有数据
+- `IDENTITY_CORS_ORIGIN`：已从 `*` 改为 `https://wangliang-crm.dev.gaia888.com`
+
+### 人工团队
+
+- `Wholesale Support`（id=1，Round robin）
+- 成员：
+  - System（id=1）
+  - agent1@yehwang.com（id=11）
+  - agent2@yehwang.com（id=12）
+- 两个 agent 的临时密码写在测试服 `.agent-credentials`（600，已在 `.gitignore` 忽略）
+- 登录验证：两个 agent 均 200
+
+### Email
+
+- SMTP 已使用本地 163 凭据配置
+- Email Inbox `Email 163`（id=3，IMAP 走 `imap-proxy:1993`）
+- Automation #3：email → `assign_team=Wholesale Support`
+- ⚠️ 本机测试服和本地共用同一个 163 邮箱，两个 LibreDesk 会同时轮询，可能重复/抢占邮件；长期测试建议用独立测试邮箱
+
+### WhatsApp
+
+- `WA_INBOX_ID=2`
+- `PUBLIC_BASE_URL=https://wangliang-crm.dev.gaia888.com`
+- 规则 #2：WhatsApp → `assign_team=Wholesale Support`
+- **Meta callback 已改到测试域名**：`https://wangliang-crm.dev.gaia888.com/webhooks/whatsapp/2`，GET 验证 challenge 200。
+  - 因为一个 Meta App 只能有一个 callback，本机 WhatsApp 已暂停接收；
+  - 如需本地和测试同时接收，需要独立 Meta App / 测试号。
+
+### 坐席邮件通知
+
+- agent1/agent2 的**邮件通知已关闭**（assignment/new_reply/SLA 等 email 渠道全部 `false`），仅保留站内通知。
+- 原因：`agent1@yehwang.com` / `agent2@yehwang.com` 在 `yehwang.com` 邮件服务器上被 550 拒绝，导致“New conversation assigned to you”退信。
+- OTP 邮件不受影响，bridge OTP 已实测可发送并送达 163 收件箱。

+# 环境差异：本地开发 / 测试 / 生产
+
+> 结论：`rpc-tunnel.sh` 和 `public-https.sh` 是**本地开发联调工具**，测试/生产环境不应依赖它们。
+
+## 1. 对比表
+
+| 能力 | 本地开发（当前机器） | 测试 / 生产 |
+|---|---|---|
+| 业务 RPC | 用 SSH 隧道 `scripts/rpc-tunnel.sh`，因为 RPC 端口外网不可达 | **不需要隧道**，直接填内网 RPC 地址（服务 DNS / VPC / 专线） |
+| RPC 地址 | `jsonrpc://<tunnel-gateway>:24503` 等隧道网关地址 | `jsonrpc://<rpc-host>:24503` 等真实内网地址 |
+| 公网 HTTPS | Cloudflare Quick Tunnel + `scripts/public-https.sh` | **不需要 Quick Tunnel**，用正式域名 + Ingress/Nginx/ALB + TLS |
+| WhatsApp webhook | 临时 Quick Tunnel URL，重启会变 | 正式域名，例如 `https://crm.example.com/webhooks/whatsapp/...` |
+| 公网路径白名单 | `public-gateway`（本地 compose 服务） | 由 Ingress/Nginx 统一处理，或保留 gateway 作为内部服务 |
+| Demo 页面 | `scripts/serve-web.sh`，:8088 | 不需要 |
+| 数据库/Redis | compose 内 Postgres/Redis，宿主机端口仅绑 `127.0.0.1` | 使用托管数据库/Redis 或内网集群，不暴露宿主机端口 |
+| 环境变量 | `.env` 指向本地/测试地址 | `.env` 指向测试/生产真实地址 |
+| 密钥 | 本地 `.env` | Secret Manager / CI/CD Secret，不入库 |
+
+## 2. RPC：本地隧道 vs 测试/生产直连
+
+### 本地开发
+
+RPC 端口外网不可达时，才需要：
+
+```bash
+bash scripts/rpc-tunnel.sh --apply
+```
+
+它会：
+
+- 在本机建 SSH 隧道到远端 RPC
+- 把 `.env` 的 RPC URL 改为隧道网关地址
+- 重建 bridge
+
+### 测试 / 生产
+
+**不要运行 `rpc-tunnel.sh`。**
+
+直接配置：
+
+```env
+RECOMMEND_URL=jsonrpc://<recommend-service>:24503
+ORDER_API_URL=jsonrpc://<order-service>:24505
+MEMBER_RPC_URL=jsonrpc://<member-service>:24506
+INVENTORY_API_URL=jsonrpc://<inventory-service>:24509
+```
+
+要求：
+
+- bridge 容器能直接访问这些地址
+- 测试/生产网络放行对应端口
+- 不要指向开发机的 SSH 隧道网关
+
+如果测试/生产网络确实隔离，应该用 **VPC 对等连接 / 专线 / VPN / 内网反向代理**，而不是开发机上的 SSH 隧道。
+
+## 3. 公网 HTTPS：Quick Tunnel vs 正式域名
+
+### 本地开发
+
+只有本地联调 WhatsApp/公网 webhook 时才需要：
+
+```bash
+bash scripts/public-https.sh
+```
+
+特点：
+
+- Cloudflare Quick Tunnel
+- URL 每次重启可能变化
+- 需要重新更新 LibreDesk `root_url` 和 Meta webhook
+- 只适合临时联调
+
+### 测试 / 生产
+
+**不要使用 Cloudflare Quick Tunnel。**
+
+使用：
+
+- 正式域名（`crm.example.com`）
+- Ingress / Nginx / ALB / API Gateway
+- 正式 TLS 证书
+- 固定公网出口
+
+配置：
+
+```env
+PUBLIC_BASE_URL=https://crm.example.com
+```
+
+并同步：
+
+- LibreDesk `app.root_url`
+- Meta WhatsApp callback URL
+- `public-gateway` 的上游地址（如果保留）
+
+### public-gateway 的去留
+
+`services/public-gateway` 只负责路径白名单：
+
+```
+/webhooks/whatsapp/
+/hc/
+/widget*
+/static/public/
+```
+
+测试/生产可以：
+
+- 继续保留它，放在 Ingress 后面
+- 或者把同样的路径规则直接写进 Ingress/Nginx
+
+Quick Tunnel 只是本地把请求转发进来的手段，不是生产架构的一部分。
+
+## 4. 测试/生产上线检查
+
+- [ ] 未运行 `rpc-tunnel.sh`
+- [ ] RPC URL 指向内网真实地址，不是 `172.23.0.1`
+- [ ] 未运行 `public-https.sh`
+- [ ] `PUBLIC_BASE_URL` 是正式 HTTPS 域名
+- [ ] LibreDesk `root_url` 是正式域名
+- [ ] Meta webhook 是正式域名
+- [ ] 数据库/Redis 不暴露公网
+- [ ] 不使用 `serve-web.sh` 的 8088 demo
+- [ ] 密钥来自 Secret Manager / CI Secret，不在仓库和镜像里
