 - **消息严格 FIFO**：队头失败并退避时，后续消息仍不能越过它。只有队头完成或按失败策略进入终态后，队列才继续推进。收报重扫和水位设计必须防止较小 ID 漏入队而被后续消息越过。
-- **动态状态单写者**：`FLIGHT_SCHD` 运营航班表和快照 `SCHD_GEN` 只由主泵单线程写入。生产单实例通过 PG advisory lock 保护，不能通过增加实例或处理线程直接扩容。
+- **动态状态单写者**：`FLIGHT_SCHD` 运营航班表和快照 `SCHD_GEN` 只由主泵单线程写入。事务通过 `PIPELINE_LOCK` 的 `FLIGHT_SCHD_WRITER` 行执行 `SELECT ... FOR UPDATE` 互斥；该方案在 PG/Oracle 11g 均无需数据库扩展或额外 DBA 特权。不能通过增加实例或处理线程直接扩容。
 - **身份去重**：同一业务身份只能绑定一条有效处理记录，重复报文不应再次产生业务副作用。具体身份组成和重放规则见设计文档。
 - **快照可恢复**：快照覆盖、旧数据清理和版本推进需要原子性与重放保护；不能在恢复时把旧代数据重新写回。
 - **作业不与消息混排**：`PUMP_JOB` 是独立队列，只在没有消息队头或队头处于退避窗口时执行。执行窗口与饥饿边界需要明确验证。

+## 9. ACM2-29 修正落盘：全宽表·零子表（Zero-Subtable Wide Table）
+
+R2 的「`*_TXT` 过渡 + 按需升独立子表」经 `docs/legacy/SIS_AODB_RMS-V0.1.md` 报文样例核验与
+成都现场（双流/天府）地服实际规律复核，确认为对 XSD 理论上限（maxOccurs="99"）的过度设计，
+正式废除。16 个明细集合全部收敛为 `FLIGHT_SCHD` 宽表的标准 VARCHAR 标量列或紧凑格式化字串，
+零子表、零 CLOB（V1.2.0 迁移落地）：
+
+- **平铺标量列**（槽位号即报文序号属性，可按需直接追加普通 B-tree）：登机门 `GATE1/2+PGOT/PGCT/GOTM/GCTM/GTYP`
+  ×2 组；值机柜台 `CHKC1..3` 全属性（同柜台分舱复用条目写侧抹平去重）；转盘 `BELT1/2` 全属性
+  （计划时刻 `BPCOT/BPCCT` 专属前缀避免与值机同名）；计划机位 `PSST1/2`；离港通道 `CHUT1/2`
+  （等级/类型 `CHCLS/CHTYP` 专属前缀）。槽位数按现场规律定界（2/3/2/2/2），超界条目按定案丢弃。
+- **单值/里程碑标量列**：延误 `DELY_CODE/DELY_STRT/DELY_DURA/DELY_REMC`（业务上任意时刻仅 1 个
+  有效延误，覆盖语义）；靠撤桥 `ABTM_A/ABTM_D`（桥号沿用派生列 ABDG）；轮挡 `CHOT_ON/CHOT_OFF`
+  （机位沿用派生列 STND）；异常 `FDIV/FRET/FLAB` 前缀标量列（规范 1:0..1 单值异常）。
+- **紧凑 VARCHAR 字串列**（无界/航路型集合，11g VARCHAR2 内联存储，非 CLOB）：
+  `ROUT_PATH/ERUT_PATH`（≤7 站紧凑航路 `"APCD/SCAT/SCDT,..."`）；`SRVT_TEXT/VIPF_TEXT/MAFL_TEXT`
+  （服务/VIP/共享列表条数无 XSD 上限，存 JSON 数组；超长由列约束 fail fast，不静默截断）。
+- **消息语义**：运营资源 = 单资源集合级全量快照替换（集合键出现即整集合覆盖，缺槽位置 NULL，
+  序号属性 "0" 为显式删除标记）；外层航班字段仍为字段级增量合并（仅新增/覆盖）。
+- **读侧视图**：由平铺列重建 16 个集合键，与 legacy `flightInfo` hash 同构——KAFKA_SCHD 线格式
+  （FLTR JSON 数组）与 FS7 Diff 逐字段比对均依赖该同构视图，存储形态变化不出仓储边界。
+  已知保真边界：`ABTM/CHOT` 只保留里程碑时刻（资源号沿用 ABDG/STND 派生列）；航路空串属性
+  与缺失属性在紧凑字串中合并为空槽位；`FDIV/FRET/FLAB` 自由文本键名待阶段 2 Handler 钉死。
+- **出站序列化**：`FlightFieldsJson` 对契约结构字段解析 JSON tree 输出原生数组/对象，
+  杜绝集合被再次编码成字符串的双重转义。
+- **I5 单写者锁修正**：不再依赖 PG advisory lock/11g `DBMS_LOCK`。V1.2.0 创建 `PIPELINE_LOCK`
+  单行锁表，处理事务对 `FLIGHT_SCHD_WRITER` 行执行 `SELECT ... FOR UPDATE`；连接断开、提交或
+  回滚时由数据库释放，PG 与 11g 同构，无 DBA 特权依赖。
+
+16 个 `*_TXT` 文本列由 V1.2.0 全部删除；运营查询索引（如 `GATE1/CHKC1/DELY_CODE`）按需以普通
+B-tree 逐列追加，11g/PG 零方言成本。
+
+Oracle 11g 的 `MERGE INTO` 方言、Flyway 11.2 支持版本和 ojdbc 认证组合仍必须在目标数据库环境
+中完成平台决策与集成验收；不能用 PostgreSQL 测试结果替代该外部环境证据。
