feat(meyer): adopt 200-image pages and batch analysis API

 从 `apps/pac-service` 执行。凭据只从 `MEYER_APP_KEY`、`MEYER_APP_SECRET` 环境变量读取；必须具备 SaaS 已同步诊所及患者所属应用的读取权限。`baseUrl` 使用 HTTPS，localhost HTTP 仅供本地模拟服务测试。
 
+### 当前接口契约（美亚 v0.4）
+
+- 影像列表使用 `query-by-clinic`，每页默认 200 张，上限 200；每轮处理条数仍受共享扫描额度限制。
+- 新扫描和待分析补查均使用 `symptom-batch`，每批最多 200 个 `imageIds`。不再向美亚发送旧的单张病症查询，也不发送患者或诊所参数。PAC 仍按诊所合批，先核对影像身份并保存影像，再查分析。
+- 批量结果按 `imageId` 关联，不依赖数组位置。缺项、空分析和单项格式异常分别留底、按原规则补查；重复或额外 ID 拒绝整批，不能错挂到其他患者。
+- 已保存的旧分页断点继续使用原 `pageSize` 完成固定窗口，下个窗口才采用新配置。不要删除断点或修改旧页大小。
+- 授权按 `accessExpiresAt` 缓存，提前 30 秒在下次调用时更新；优先轮换一次性 refresh token，失败或网络结果不确定时丢弃旧 refresh token，再用应用凭据签发。并发调用及同一客户端的不同时间窗口共享一次换取操作。
+- HTTP 401 或封套 `code=401/401001` 仅触发一次重新认证与业务重试。到期时长以美亚返回值为准，不写死为两小时或七天；令牌不写入文件或日志。
+- 不依赖 Java SDK，不新增影像事件推送；继续由现有单一定时器轮询。
+
 复制 `config.example.json` 到仓库外，填入允许采集的 clinicIds 和时间范围；namespace 是稳定的应用来源名，不要随运行改变。状态目录按环境和应用隔离，包含患者数据，应受权限及备份策略保护。

 ## 本期取舍与上线前核实
 
-- 已用测试患者完成真实只读联调：PDF 三项身份参数可用，分析可落库，文件 ID 可换取 OSS 签名地址。详见 QA 记录。
+- 历史联调记录中的单张三项参数属于旧契约；当前按上节 v0.4 批量接口执行。文件 ID 继续按既有接口换取 OSS 签名地址，文件地址接口的上限仍为 100，不能与影像列表/分析的 200 混用。
 - 无更新游标、完整快照分页和删除标记，无法承诺完整生命周期同步；分页数量变化、重复/缺页会报错，重跑固定窗口。只在空响应和缺字段时延后，不能把它们当作阴性结论。
 - 宿主若以后推送同一批美亚影像，必须先统一来源标识和接入责任，避免与本路线重复。首期应只开明确授权的试点诊所。
 - 测试环境曾运行固定窗口联调；这不等于已启用持续任务。启用前应核实实际进程、启动配置、持久状态及扫描水位。开发回归使用本地 HTTP 与独立 PostgreSQL 数据库。

 达到分析次数上限后，人工确认需要补查时，可使用同一配置、同一持久状态目录，把固定窗口限定为对应影像入库时刻，再执行默认单次命令（`--apply`，不带 `--tick/--watch`）。这次显式查询可越过等待时间和次数上限；若仍为空或异常，继续保留人工状态。它不绕过影像类型、身份或落库校验，也不重算已完成分析。

docs/qa/2026-10-21-meyer-batch-contract.md

+# 美亚 v0.4：200 条分页、批量分析与授权更新
+
+## 范围
+
+- 分支：`codex/meyer-clinic-isolation`，基线 `ff1c039`；本轮修改未提交、未合并、未部署 PAC。
+- 依据：2026-10-21 提供的《PACS_瑞尔接口对接文档.md》v0.4 与 Java SDK；文件指纹见 `output/meyer-batch-20261021/vendor-inputs.json`。
+- PAC 保持直接 HTTP 对接，不引入 JAR。按本轮确认不接入影像事件推送，沿用单一定时器。
+
+## 改动
+
+- `query-by-clinic` 的配置默认值及响应校验上限改为 200；现存 100 条分页断点完成后才切换新大小，不删除游标或留底。
+- 新扫描和到期补查使用 `symptom-batch`，只传 `imageIds`，每批最多 200。同一诊所先完成影像身份校验和影像保存，再合并分析请求。
+- 结果按影像 ID 对应。省略项、空分析、单项格式错误分别留待补查；额外或重复 ID 拒绝整批。分析次数与补查时间仍逐张持久化，已应用快照不重复拉取。
+- 保留原诊所隔离、整轮额度、分析降频/上限和身份异常最多 8 次补查。身份重读阶段为已核实影像预留一次分析请求，避免小额度只反复查列表。
+- access token 按返回的到期时间提前 30 秒更新。共享同一客户端的并发换取；优先刷新，丢弃结果不确定的一次性 refresh token 后回退应用凭据签发。HTTP 401、业务码 401/401001 最多触发一次重认证与重试。
+- 原标准字段、临床映射、时区、FactWriter 和画像/召回判断未调整。文件 URL 接口上限仍为 100，不随影像列表和分析扩到 200。
+
+## 美亚测试接口实测
+
+2026-10-21 14:54（北京），使用当前测试配置访问 `https://re-pacs.myyun.com/api/v1`，仅查询及签发/刷新测试会话，没有写入 PAC 或修改美亚业务数据。
+
+| 项目 | 结果 |
+|---|---|
+| 列表请求每页 200 | 返回 `size=200`；本次诊所和时间范围共 58 张 |
+| 批量 58 张已有影像及 1 个不存在 ID | 返回 58 项，不存在 ID 被省略 |
+| 非空分析 | 本次返回 2 项；不据空视图认定阴性或分析已完成 |
+| 抽取 3 张全景片与单张接口比较 | 结果一致 |
+| 临近过期刷新 | refresh token 正常轮换；新 access token 剩余约 7200 秒 |
+
+脱敏结果：`output/meyer-batch-20261021/vendor-validation.json`。实测只代表当前测试配置，不推断生产是否共用同一美亚应用。
+
+## 本地验证
+
+- 新增批量/授权用例 14 项，覆盖 200 张合批、缺项、重复/额外 ID、空和异常结果、并发授权、401001、刷新网络异常、旧分页断点、写入恢复及极小请求额度。
+- 原有影像摄入、诊所隔离、身份恢复、补查上限和文件访问回归通过；诊断映射 40 项通过。
+- 独立本地 PostgreSQL 16 项通过：批量 HTTP → 归一 → 真实事实写入；影像先保存、晚到分析更新同一影像、空/缺项保留补查、重复执行事实不变。临时测试库已清理。
+- 后端源码及测试类型检查、构建、差异格式检查通过。
+
+测试日志与构建日志在 `output/meyer-batch-20261021/`。未修改测试/生产 PAC 的采集配置、定时器、业务数据或部署版本。
