+# A5 Map Label Integration
+
+## Launch Contract
+
+`pages/a5/index?phone=13800138000&link_id=42`
+
+- `phone`: auto-query phone; manual query remains available without it.
+- `link_id`: A5 link ID for configuration, business documents and completion files.
+- Legacy `/h/<id>` scenes and URL Link encoded separators are accepted.
+- No corp token, host, package or default short link is used by A5.
+- agent-h5 resolves the link from `agentLink.linkId`, `linkId`, then `/h/<id>`.
+
+## Environments
+
+- Development: `TARO_APP_API_A5=http://ag-test.batiao8.com`
+- Production: `TARO_APP_API_A5=http://ag.batiao8.com`
+
+HTTP is configured as requested. Before a WeChat release, provision HTTPS with a valid certificate and update the environment value. Configure request/upload/download legal domains, including returned file CDN domains. HTTP is not a release-ready WeChat endpoint.
+
+## API Contract
+
+- `GET /h5/link?id=<link_id>`: link configuration and customer service.
+- `GET /h5/order?phone=...&page=1&size=20&status=2`: paid orders, filtered to map_label. This follows the H5 first-20 query behavior.
+- `PUT /h5/order`: `{ id, biz_info: JSON.stringify(...) }`.
+- `GET/POST /h5/file`: `link_id`, `LinkId`, `scene`, `scene_id`; uploads use multipart field `file`.
+- `DELETE /h5/file?id=...`: delete a document.
+- Business scenes: license `order_biz1`, storefront `order_biz2`, identity `order_biz3`.
+- Storefront uploads carry `extra.loc` (front/left/right labels in Chinese).
+- Completion scenes: `order_process_gd`, `order_process_bd`, `order_process_tx`.
+- Complaint: `POST /api/user/feedback`, matching agent-h5's declared API contract. This route was not found in the local agent-api router. Per the requested temporary UI behavior, only HTTP 404 for this POST is treated as success so the page shows its normal success message and returns. No feedback is persisted in that case. Other HTTP, business and network failures still surface. Remove this fallback when the endpoint is available.
+
+The H5 development proxy removes its `/api` prefix. Mini-program business requests therefore use `/h5/...` directly, without corp signing, token bootstrapping or presigned Qiniu upload.
+
+## Verification
+
+- `pnpm test`
+- `pnpm build:weapp`
+- In agent-h5: `pnpm exec vitest run src/utils/weixinMiniProgram.test.ts src/ui/map_label/utils/miniProgramEntry.test.ts`
+- In agent-h5: `pnpm build`
+
+Open the mini-program project in WeChat DevTools, using `dist` as the mini-program root. Set the compile page to `pages/a5/index` and use an authorized test phone and matching A5 link ID. Check auto-query, pending-submission status, three required storefront slots, optional license/identity slots, example previews, map return, deletion, resubmission refresh, platform screenshots, PDF opening and complaints. Revisit the original index to verify it still uses the corp service.
+
+No real customer orders were submitted or modified during implementation verification.
