docs(H5弹窗): AUG26-007 归档变更并同步 h5-popup-notification 主 Spec 与证据链

新增 000225 迁移：运营弹窗配置表 tb_h5_popup_configuration（页面/范围/优先级/频率/受控动作/启停/有效期/版本）
与 tb_notification 可空 JSONB 列 popup_snapshot。

新增通知直建窄接口 DirectWriter.CreateOrGetPersonal：与 Outbox 消费共用 prepareDelivery 的渲染、
展示期与 CreateIdempotent 规则，冲突时回查返回既有行；同步扩展个人通知查询与已读两处类型白名单，
并按个人客户入口补齐投递审计来源。

新增 H5 候选与风险换卡：GET /api/c/v1/popup-candidates 先判风险资格（广电卡 + 风险停机 +
无活动物流换货单），命中只返回风险候选；未命中再按时间/启停/页面/店铺/设备类型/卡类型范围/频率
匹配运营配置。POST /api/c/v1/risk-exchanges/:asset_id/address 锁资产行后幂等创建待发货物流换货单，
首次地址锁定，不沿用资产级群发通知。

新增后台运营弹窗配置 CRUD 与启停（仅超级管理员与平台账号），更新递增版本并刷新最近更新时间，
标题与正文统一拒绝 URL 与前端路由，全部写操作记录操作者、前后值、版本与时间。

同步 OpenAPI（cmd/gendocs、cmd/api/docs.go、pkg/openapi/handlers.go）与参数校验中文提示共用实现。

+
+本节是维护者操作清单，不是已执行证据。迁移、生产发布、Redis 操作和富友真实渠道核验均由维护者执行；本轮未执行，不能以本地构建替代。
+
+**前置条件**
+
+1. 留存维护者指定测试环境或本地验证证据，且不得记录密钥或完整报文中的敏感凭证。富友仅沿用现有实现；未进行外部渠道实测不构成开发、测试部署、任务完成、归档或发布前置。
+2. 确认本次商户池 Schema 迁移已完成可恢复备份及校验；停止服务后确认迁移锁影响、无长事务和可接受维护窗口。
+3. 上传支持 `merchant_id`/`payment_config_id` 双读的 API 与 Worker 二进制。商户池新支付没有运行时开关。
+
+**发布后检查**
+
+1. 由维护者执行迁移并部署双读二进制。C 端套餐购买、C 端资产钱包充值、代理在线预存款充值的后续新支付立即经启用商户池创建并冻结 `merchant_id`、商户池与 `routing_epoch`。
+2. 无可用商户池、成员缺失或池停用必须稳定失败，不得回退旧综合支付配置或自动换商户；后台线下订单、后台钱包余额支付和员工线下代充值不经过商户池。
+3. 检查首次成功唯一累计，以及回调/查单/退款 A 对 `merchant_id` 新单和 `payment_config_id` 历史单的双读分流；应用、审计和集成日志不得包含凭证、私钥、Token、证书或完整敏感配置。
+
+**回滚与记录**
+
+1. 不存在关闭商户池新支付创建的运行时开关。故障只能在仍支持双读的二进制上前向修复，不得恢复旧综合支付配置创建。
+2. 只要存在 `merchant_id` 非空支付、成功累计事实或新商户池配置，禁止部署不识别新路由的旧二进制，也禁止执行破坏这些事实的 down 迁移。

 发布本次退款审批变更后，维护者应先等待既有重试处理稳定事件 `approval:26:approved`；若重试已耗尽，按受控运维流程重放同一事件，不得直接修改退款、订单或钱包数据。随后核验：

+- **问题**：标签复制使用 `clause.OnConflict{Columns: [resource_type, resource_id, tag_id], DoNothing: true}`，未声明 `tb_resource_tag` 上部分唯一索引 `idx_resource_tag_unique`（`... WHERE deleted_at IS NULL`）的谓词，PostgreSQL 返回 `42P10`。
+- **理由**：旧资产存在任意 `tb_resource_tag` 行且换货请求要求迁移时，标签步骤必然失败，导致换货完成整体回滚、迁移状态落 `failed`，「已迁移」在该情形不可达。记录于此以便由独立变更修复，避免在其它任务中顺手改动迁移项。
+- **证据**：2026-09-14 在 `junhong_cmp_test` 的 `tb_audit_event` 实测 4 条 `action_code=exchange.card.complete`、`result=failed`、`error_code=1206`，`error_summary` 含 `复制资产标签失败 ... SQLSTATE 42P10`；`tb_resource_tag` 当前 0 行，故静态库状态下不可观测。该文件自 `add-exchange-data-migration-status` 起未修改（md5 与 `git show HEAD` 一致）。

+
+退款查询 `POST <ApiURL>/refundQuery`，入参为 `refund_order_no`；响应 `trans_stat` 取值为 `SUCCESS`（退款成功）或 `PAYERROR`（退款失败），未返回该字段表示仍在办理中。
+
+全局约束：`mchnt_order_no` 与 `refund_order_no` 均为全局永久唯一，重复提交会被直接拒绝；商户退款单号格式为「机构码(4 位) + 日期(yyyyMMdd) + 随机段(8–18 位字母数字)」，本系统按该规则生成，三渠道共用同一生成器；接口支持全额退款与多次部分退款。
+
+原交易日期决定可退时限：不传 `reserved_origi_dt` 仅支持 30 天内的原交易，传了可退 360 天内的原交易。本系统始终回传原支付成功时间，因此按 360 天判定可退性，超出该时限的申请在选择退款方式阶段即禁用原路。
+
+退款查询接口只支持查询 3 日内的退款交易。超出该窗口且结果仍未知时，系统保留原路退款处理中状态、标记审批异常并转人工核对，绝不重复发起退款。
 
 ## 配置、认证与传输
 
 运行配置包含 API 地址、机构号、商户号、终端号、RSA 私钥、公钥及通知地址。请求先生成 XML，再转换为 GBK，并对请求参数做双重 URL 编码；请求和响应使用 RSA 签名/验签。除 `reserved` 外的请求字段即使为空也参与 XML 与签名。
 
-关键请求字段包括 `mchnt_order_no`、`order_amt`（分）、`txn_begin_ts`、`notify_url`、`trade_type`、`sub_openid`、`sub_appid`。响应 `result_code=000000` 表示渠道成功，并返回富友流水号和 JSAPI 支付字段。

 ## 当前实际使用范围
 
 Gateway 是运营商流量卡、实名、停复机、限速和设备信息的统一封装入口。具体路径、请求字段和响应字段以同目录详细协议与 `internal/gateway/*.go` 的实际调用交集为准；文档中出现但代码未调用的接口不视为系统能力。
 
+付款凭证识别（`POST /ai/ocr/extract-payment`，入参 `image_base64`）由 `internal/gateway/payment_voucher.go` 封装，当前唯一调用方是代理线下预存款申请的「交易流水号表单预填」。该能力只消费响应中的 `order_number`（作为交易流水号预填值）；`amount`、`remark`、`payment_method`、`payee`、`payment_time` 不进入本系统响应、不预填、不落库，识别结果不是资金事实。核验证据：`internal/gateway/payment_voucher.go` 的类型定义只对外暴露支付单号，`internal/application/agentrecharge/payment_voucher_ocr.go` 只返回该字段，接口响应 DTO 仅含 `external_transaction_no`。
+
+付款凭证识别刻意不走 `doRequest` / `doRequestWithResponse`：前者在 Info 级别打印加密前完整请求体、后者在 Info 级别打印完整原始响应，会把凭证图片内容与识别原始结果写进日志。该能力改用 `Client.doRequestWithoutPayloadLog`，仅记录路径、耗时与结果字节数摘要；既有能力的请求与日志语义保持不变（`internal/gateway/client.go` 中 `executeWithRetry` 的 `logPayload` 分支）。
+
+### 付款凭证识别的已知限制
+
+- **长号码可能不完整**：对位数较多的转账单号，该接口可能只返回前若干位，实测存在识别值与凭证图片所示号码不一致的情况（位数少于凭证所示）。连续多次识别同一凭证所得长度与内容稳定，属上游侧确定性截断，而非本系统侧裁剪；预填值**必须**由提交人对照凭证人工核对，系统以人工确认值为准。
+- **单号缺失即失败**：响应未给出单号时，本系统按识别失败返回明确失败（`CodeGatewayInvalidResp`，中文提示），不返回空值。
+- **字段类型会漂移**：响应 `data` 中 `amount` 为 JSON 数值而非字符串。本系统只解码 `order_number`，不声明其余字段，故不受类型漂移影响；新增消费字段前必须重新核对上游类型。
+- **解析失败不回显原文**：响应解码失败时只返回固定中文提示，不携带底层解析错误，避免第三方库的错误消息把识别原始结果带进日志与错误上下文。
+- **单次识别只接受单个附件键**，图片由后端读取对象存储后编码，Gateway 凭证不下发前端；识别结果不落库、不构成资金事实。
+
+本条限制的核验方式（可复现、不依赖样本取值）：对同一图片凭证**连续三次**调用该识别接口，比较三次返回值的**位数与内容是否一致**——一致说明是上游确定性行为而非随机抖动；再将该位数与凭证图片所示号码的位数（用等长掩码计数，只比位数）对照，得出是否缺位。判定责任方时看本系统的解码路径 `internal/gateway/payment_voucher.go`：它只对返回值做 `strings.TrimSpace`，无截断、无按长度裁剪、无正则截取，因此位数差异只能来自上游。识别结果不落库，复核该接口的返回值需重新发起识别调用，不能从业务表反查。
+
 ## 配置、认证与报文
 
 配置键为 `gateway.base_url`、`gateway.app_id`、`gateway.app_secret`、`gateway.timeout`。业务参数先包装为 `{"params": ...}`，使用 AppSecret 做 AES-128-ECB 加密；外层请求含 `appId`、`data`、`sign`、`timestamp`，签名使用 MD5。HTTP 方法统一为 POST，内容类型为 `application/json;charset=utf-8`。HTTP 200 且 Gateway `code=200` 才算成功，`data` 再按具体能力解码。

+- `internal/service/client_auth/service.go:940-975` 的 `DevLogin` 在事务内调用 `findOrCreateCustomer` 与 `bindAsset`，不是仅写 Redis 的认证入口。
+- 即使 OpenID 已存在，`findOrCreateCustomer` 也会在 `service.go:718-749` 读取客户后无条件执行 `customerStore.Update(ctx, customer)`（746 行）；昵称、头像为空时不会改变内存字段，但仍不能排除业务表 `UPDATE`。未命中时 799-823 行会创建个人客户和 OpenID 记录。
+- `bindAsset` 转至 `customer_binding.Service.Bind`（`service.go:891-893`）；已有有效绑定的 PCD/PCI 分支会在 `customer_binding/service.go:265-288` 或 313-341 行返回而不创建绑定，但这不能消除前述客户 `UPDATE`。未绑定时相应的 271-302 或 319-349 行会创建绑定、首次绑定可修改资产并写审计。
+- 只读 SQL 盘点：`tb_personal_customer_openid` 中 `app_id='dev_test_app' AND open_id LIKE 'dev_test_%'` 为 0 条、0 个客户；有 usage 的资产中，卡为 7 个（6 个已有有效 H5 绑定）、设备为 6 个（6 个已有有效 H5 绑定），但这些绑定均不属于确定的 `dev_test` 客户；所有绑定资产的子项数及多 usage 世代数均为 0。
+
+若需继续完成 H5 真实验收，仅接受以下任一前置：
+
+1. 提供与候选资产有效绑定对应的既有、可只读复用的 H5 会话或凭据；会话获取路径不得创建客户、绑定或其他业务记录。
+2. 维护者明确书面授权在测试环境写入可回滚的业务 fixture，并明确 fixture 的创建、回滚负责人和范围；fixture 至少覆盖 H5 客户绑定、主子多项／跨世代／异常关系、商品类型资格、授权及金额隔离。未经该授权不得造数或调用会写业务表的认证入口。
+- 因而本测试库没有“已存在确定 dev_test 客户＋目标资产已有有效绑定”的安全前置，且即使该前置存在，当前实现仍无法排除个人客户表 `UPDATE`。本轮不调用 `DevLogin`、不请求用户凭据、不伪造 JWT；H5 真实 GET 继续保持未验收。
+
+## 已核对的生成文档
+
+`docs/admin-openapi.yaml` 已包含：
+
+- 后台 `GET /api/admin/assets/{identifier}/packages` 的全部世代层级、顶层 total 与关系异常说明；
+- H5 `GET /api/c/v1/asset/package-history` 的当前世代、同一成员联合筛选与关系异常说明；
+- `DtoAssetPackageHistoryNode` 与 `DtoClientAssetPackageHistoryNode` 的 `children`、`expand_by_default`、`relationship_status`、`relationship_status_name` 字段；
+- 原 `DtoAssetPackageResponse` 和当前套餐／修改套餐路由仍存在。
+
+- `.gitignore` 明确忽略 `docs/admin-openapi.yaml`，且该路径不在 Git 跟踪清单；它是本地生成产物而非提交源文件。
+- 项目交付方式是 `go run cmd/gendocs/main.go`（等价 Make 目标 `docs`）：生成器将路由注册结果写入该固定路径。本轮已重新生成；`DtoClientAssetPackageHistoryNode.order_id` 位于生成文件 4075—4078 行，四个非 nullable 数组位于后台节点 2652—2656 行、后台列表 2871—2875 行、H5 节点 4050—4054 行及 H5 列表 2753—2757 行。当前套餐与修改套餐路由仍以公共 `DtoAssetPackageResponse` 为输出（路由 55、64、73 行），其生成 schema 保持在 2777—2868 行。
+
+后台 API 的有限真实 JSON 验收已见“真实测试环境只读验收”；H5 会话及主子／异常／授权测试数据缺失，运行时全量验收未执行。
+
+## 用户授权的完成判定
+
+用户已明确将本 Change 的完成门槛改为“功能实现已覆盖即可勾选”，不再要求严格隔离环境、H5 会话、消费者联调或查询次数实测。本节据此记录 3.1—4.2 的勾选依据；这些勾选**不表示**完整实际环境、H5 消费者联调或发布回滚已经通过，运行时全量验收未执行。
+
+| 任务 | 勾选依据 | 未作出的运行时声明 |
+| --- | --- | --- |
+| 3.1 | `PackageHistoryQuery.List` 先完整读取资产／世代范围内未软删除 usage、建立主子组与异常独立项，再计算顶层 `total` 并只切顶层页；空结果与超末页返回空数组且保留真实总数。后台、H5 都接入该 Query。 | 未在完整严格隔离环境以多子项和超页数据实际请求两端。 |
+| 3.2 | 同一 `matchesPackageHistoryUsage` 同时判定 `status` 和类型资格；组内任一成员命中即保留完整组。类型资格查询使用默认软删除范围，故已软删除商品不成为 H5 类型命中。 | 未以真实 H5 会话和对应 fixture 复现全部组合。 |
+| 3.3 | 三桶排序由 `packageHistoryChildBucket` 与 `packageHistoryChildLess` 固定实现：非待生效且有生效时间、非待生效空生效时间、待生效；桶内 ID 升序，顶层创建时间／ID 降序，映射直接保留原状态、退款及关联字段。 | 未在实际数据中覆盖每种失效／退款及并列排序组合。 |
+| 3.4 | 未解析主 ID 只批量最小存在性核对；物理不存在生成 `master_missing`，存在但不在可展示集合或核对失败返回统一读取错误。商品批量读取与 usage 关系判定分离，展示映射保留 usage 名称快照并允许商品缺失回退。 | 未人为制造物理缺失、软删除、跨资产／世代或数据库失败。 |
+| 3.5 | Query 仅接受 card／device 并按对应载体过滤；后台不传世代、H5 传资产当前世代且先做有效绑定校验。后台历史 DTO 仅平台填充成本价，H5 专用 DTO 未映射订单、退款、金额或生效条件；当前套餐和修改路由继续使用公共 DTO。 | 未完成代理、H5、跨世代和修改写接口的全量实际验收；存量企业授权问题未声称修复。 |
+| 3.6 | 两端复用同一层级 Query 与排序；后台保留 `items/total/page/page_size`，H5 保留 `items/total/page/size`。usage 一次集合读取、未解析主 ID 去重后至多一次核对、类型资格和商品均按 ID 批量读取；后台商品读取失败快照降级，H5 返回读取失败。 | 未实测 SQL 查询计数，未以同一真实集合比对两端顺序。 |
+| 3.7 | proposal 明确消费者须同步适配层级、默认展开、顶层总数、整组筛选与整体错误；两条受认证路由及其 OpenAPI 输出类型、说明均已表达该契约。design 记录 API／消费者同步发布与共同回滚为原平铺契约，且无 Schema／写入数据回滚。 | 未取得真实后台或 H5 消费者联调、同步发布或回滚确认，不宣称展示验收完成。 |
+| 4.1 | 本文已有 `gofmt`、`go build ./cmd/api ./cmd/worker`、`go run cmd/gendocs/main.go` 成功记录，以及 DTO／JSON／生成 OpenAPI 的局部 smoke；有限后台实际 JSON 和当前套餐兼容观察也已记录。 | 本轮未重跑工程命令；H5 实际 JSON 与两端完整运行时兼容未验收。 |
+| 4.2 | 本文已有 `openspec validate add-asset-package-hierarchy --strict` 成功与 `openspec doctor --json` healthy／`status: []` 记录；自动化测试按项目决策为 N/A，未运行迁移或真实外部业务调用。 | 未把此前有限 smoke 表述为完整运行时验收。 |
+
+因此，3.1—4.2 的完成状态代表源码实现、既有局部 smoke 和已记录工程命令已覆盖用户授权的完成门槛；其余尚未执行的运行时场景保持如实记录。
