+- `PATCH /api/auth/me` 同样要求幂等键。`POST /api/auth/change-password` 是例外：其成功响应包含新 access token，不能将该 token 持久化到幂等回放表；客户端不得自动重试此操作。
 - 更新可编辑资源时，读取响应携带 `revision`；客户端在 `PATCH`/`PUT` 中提交 `If-Match: "<revision>"`。版本已变化返回 `409 VERSION_CONFLICT` 和最新 `current_revision` 摘要。`revision` 是并发控制版本；不要把水印的渲染 `current_version` 当作它。
 - 耗时动作（店铺凭据验证、仓库同步、媒体处理）先返回 `202 Accepted`，并在资源中返回 `operation`。客户端轮询 `GET /api/operations/{operation_id}`；后续可追加 SSE，不改变资源接口。
 - 所有启动异步工作的业务写入，必须在同一 PostgreSQL 事务中写入业务资源/`operation` 和 `outbox_events`；独立 Dispatcher 再投递 BullMQ。BullMQ 和 Redis 不得作为任务存在或最终业务结果的唯一事实。
