"""M11b-2c: 测试夹具 DDL 与列契约对齐补丁（只改 tests/，不动业务代码与表定义 JSON）。

根因（实测）：tests/test_m11b2_single_tx.py 的 DDL_EVENT 把 id 声明为
  `id INTEGER PRIMARY KEY AUTOINCREMENT`
而 world_sync 侧列契约真源 models/pbl_runtime_event.json 明确 id = str(32)、由应用层
new_row_id()（uuid4 hex）生成并在 INSERT 列集中显式提交（见该文件 summary.comment
「id 生成方 · 单一口径，QC #4」）。写路径插入 32 位十六进制字符串到 INTEGER 主键列
=> sqlite3.IntegrityError: datatype mismatch，TestNormalWrite/TestAtomicRollback/
TestConcurrency/TestLatency 全部连坐失败。属夹具建表与契约不一致，修夹具即可。

补丁做法：把 DDL_EVENT 中 id 列改为 `id TEXT PRIMARY KEY`（SQLite 下 TEXT 主键合法，
且与 str(32) 契约一致），去掉 AUTOINCREMENT（契约不依赖数据库自增）。
