"""冻结幂等键（manifest, context）对真实库集成测试。
|
||
|
||
example_context_freeze 是 append-only 表（触发器禁止 UPDATE/DELETE），
|
||
无法物理清理测试行；因此本测试零新增：回读一条既有冻结行，按其
|
||
manifest+context 原值重放，验证幂等回读同一行、不新增。
|
||
|
||
"同清单不同上下文各得其所"由 2026-08-23 两阶段烟测实证（候选 164 的
|
||
冻结在旧 manifest 单键下永远落不了库，迁移后落库成功并通过接受前置检查），
|
||
并由迁移 114 的 (manifest, context) 唯一索引在库级保证。

||
|
||
跑法（需可达 muse-example）：
