ThearchyHelios 2f90f0eb3a 口径台账：固定执行、验证审阅发布与增量重导入 
- QueryCore 固定执行（K09）：按已发布的不可变口径跑一次，交回类型化标量、发布/manifest 引用与逐查询证据
- 依赖闭包（K08）：按选中的指标算出要拷的取数节点、要的入口字段，接进 derive / compose / metrics
- SQL 模板参数完整性（K01）：试跑、组合问数、派生图、运行时取数共用一套语义，缺参数在渲染前就拒
- 受限字段变更服务（K03）与口径领域边界（K01）：改动打在整图深拷贝上，身份与证据归属不可改
- 版本化受控模板绑定（K04）：业务口径按显式绑定落到 SQL，对不上就报 unsupported / needs_update
- 验证记录（K05）与最小审阅：样例匹配不等于正式批准，审批人只从服务端身份取
- 发布依据清单（K07）：发布时按不可变图物化内容寻址清单，正式用途按它判
- 增量重导入（K11）与 B/L/R 三方合并、受限自然语言修改提案（K12）：只产候选，落图仍走既有写路径
- 接口与前端：口径草稿页接上字段变更、绑定状态、验证与重导入，新增 caliber-drafts / studio 检查脚本

验证：前端 tsc -b 通过。

"""SQL 模板参数完整性（开工任务书 v3 · K01，§4.4）：ledger/params 一套语义，各入口同一结果。
- 认模板里的参数（引号里的字 / 裸写 / 注释里）、未声明的字段、缺值的字段（含声明成可选、又没有缺省值的）；写在表名列名
里、认不出写法的照实拒（单元一层，函数返回机器码）；
- 组合式问数拷进来的取数节点：值在拷的时候渲染进 SQL（只渲染这一次），节点上写一份与**这条渲染好的 args** 绑定的
参数契约：跑一次真实的问数运行，断言**实际发给数据库的那条 SQL** 就带着值里的 {{ }} 文本（字面量，不再被解释）；
- 契约与它注解的语句绑定哈希：复制走、改过 SQL 之后契约作废，那个节点回退成普通模板（正常渲染、正常判参数，带 {{ }}
的语句绝不原样发出去）；
- 派生图（口径探针）同样：入口参数值里的 {{ }} 是字面量，各入口同值同语义；
- 缺参数（声明成可选、没有缺省值；开放入口里显式传了空串）、未声明参数：**零 SQL**——数一下 run_query 被调了几次，就是 0；
显式空串算没给，作者声明的 `default=""` 才算声明式省略（两条都有真实运行反例）；
- 查询快照记源模板哈希、规范化输入哈希、参数契约与写在哪儿，承载方式照实写 inline_text（不假装驱动绑定）；
- 对账图里「这次的取数」放的是执行过的语句：运行时的模板渲染不再碰它。
数据是虚构店铺库（tests/ledger_samples.py）。
