ThearchyHelios 538799e70d 沉淀:认证队列、固化成口径草稿、发布后补比;账本统计补上对账与认证队列的转化(口径账本做法 8、10,拍板 L9)
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)。

"""账本(BE-3,只读):工作流版本被哪些应用钉住、生效计数;生效记录查询。设计文档 §2.9 L4。
不另建存储:ActionRecord 本身带着工作流、版本、graph_hash、能力版本、payload_hash、回执;「口径 → 应用」就是固定这一版的
应用版本。用在发布弹窗、退役确认、版本列表三处。
口径账本(docs/design/next-round/02-口径账本.md)在这里加的接口:
- GET /api/runs/{run_id}/ledger(runs_router,和证据同一道门):一次运行里每个数的口径标签、整题判断、每条查询的比对、能做的
动作、出具过的正式运行、对过的账(app/ledger/view.py);
- GET /api/ledger/stats(router,搭建者):账本自身给出的统计 E1–E4,从比对工件、运行、审计现算(app/ledger/stats.py);
- POST /api/ledger/answers/{run_id}/issue(answers_router,登录即可,第 3 波):按口径正式出具(app/ledger/issue.py,拍板
L1、L5:参数只从比对工件取,使用者只能按他有权使用的应用固定着的版本出具);
- POST /api/ledger/answers/{run_id}/reconcile(同上):口径对账,点开才跑一次确定性派生的只读图(app/ledger/reconcile.py);
- GET /api/ledger/certify-queue、POST /api/ledger/certify-queue/dismiss(router,搭建者,第 3 波):可沉淀的问题、「不是口径」
(app/ledger/certify.py)。这几个新接口都不放给访问密钥(auth/keys.KEY_ROUTES 不登记)。
