为什么：同一类问题被反复问、Agent 反复写出同一个形状的 SQL，就该沉淀成一份口径；以前 from-run 保留 Agent，沉淀出的模板没有固定 SQL，以后永远比对不上。第 2 波的统计在 E2 反馈、E3 认证队列上照实写了「目前没有数据」，这一波补上能补的。
做了什么（新增 ledger/certify.py）：
- GET /api/ledger/certify-queue（搭建者）：确定性重复（问数据运行里被报告引用、没对上口径的查询，按数据源 + normalize_sql 文本分组，≥3 次运行且来自 ≥2 段对话；跨运行变化的字面量是参数候选，展示的形状不带取值）、问题聚类（app/chat/questions 全站唯一的那份）、被反复用的答案（导出 ≥2 次用第 2 波的 report.exported 审计、做成过应用看蓝图来源、在画布里打开或提取过看工作流 origin）。每项给代表问题、轮次、相关口径、是否已固化。
- POST /api/ledger/certify-queue/dismiss：「不是口径」写审计 ledger.certify.dismiss，之后不再进队。
- 固化成口径草稿（from-run 加 freeze、peers 后转调 certify.freeze）：报告引用的查询变成固定 SQL 的取数节点，跨轮变化的字面量换成 '{{ input.pN }}'（缺省值取代表运行的），单行结果的数值列成口径卡指标，报告核对规则按受管要求写、契约 report_from + metrics_from + required（多行加 cells）；过 validate_graph 和受管门禁。新工作流 origin.sources 记来源问题。
- 发布之后补比：api/workflows.commit_publish 提交后调 certify.after_publish，来源运行按新口径补比一次（新的 trigger=certified，界面写「按之后发布的口径回看」，时间线和账本接口同一句）。
- 统计：E2 加对过账的答案数、参数经人核对的、指标由人选的次数（反馈照实写第 4 波）；E3 认证队列的转化（固化、发布、不是口径）。
测试：tests/test_ledger_certify.py（参数推断与模板、三种信号进队、门槛、不是口径、固化草稿过受管门禁、发布后来源运行补比成等价已证明并出队、再问标等价已证明、统计）。

"""沉淀：可沉淀的问题（认证队列）和「固化成口径草稿」（next-round 02 做法 8，app/ledger/certify.py）。
|

|

真的跑三次问数据（两段对话、同一个 SQL 形状、日期不同，虚构店铺库），等后台比对做完：
|
||
- 队列：确定性重复进队（3 次运行、2 段对话），变了的字面量是参数候选、不变的是常量，形状里不带取值；同一个问题问了 3 次
|
||
进问题聚类；导出过两次的、做成过应用的答案进「被反复用的答案」；点「不是口径」写审计后不再进队；
|
||
- 固化：报告引用的查询变成固定 SQL 的取数节点，跨轮变化的日期成为入口参数（缺省值取代表运行的），常量 'paid' 照写；单行
|
||
结果的数值列成口径卡指标；出口契约 report_from + metrics_from；过 validate_graph 和受管级别的发布门禁；origin.sources 记

「等价已证明」；

- 统计 E3：认证队列的转化（固化、发布、不是口径）有数了。
