- 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。

"""K10：同一份查询快照被执行两次（两条一模一样的取数）时的证据身份与消费。
|
||
|
||
同一次运行里两条完全相同的查询（循环里同一个节点跑两次、或者两个节点写了同一条 SQL）结果一样、查询
|
||
快照的内容 id 也一样（内容寻址：同内容只存一份）。以前按 artifact 认，第二次会把第一次盖掉：
|
||
|
||
- 封存读取（engine/evidence_reader）：sealed.queries 是按 artifact 的，两条并成一条；
|
||
- 目录与 make_eid（engine/evidence）：两条 query 条目的 eid 一模一样，图上、文档里分不出是哪一次；
|
||
- HTTP 证据（api/evidence）：点开 [[v:Q2.r0.x]] 时出处链又把 artifact 反查成 Q1；
|
||
- 应用取快照（apps/resolve）：同一节点的两次执行并成一条，exec 取第几次就不准了。
|
||
|
||
这份文件盯住这几条，并保证旧行为不变：**新条目**（带 query_id / execution_id / attempt）按
|
||
(artifact, node_id, exec, execution_id) 这一类复合身份索引，同一份快照两次执行各得一个 eid、两条点得开的
|
||
记录；**老条目**（一个执行身份字段都没有）照旧只按 artifact 算 eid、按 artifact 找，一个字都不变；
|
||
旧文档、复算、重放不变量都不受影响。
|
||
|
||
数据全是合成的（虚构零售库的一份地区销售额快照、真跑一次 app.analysis 的结论），落成一次封存运行后走真实的
|
||
HTTP 证据接口与真实的复算，不连真实业务库、不读密钥。工具/模型可见的结果里不因此多出 SQL 正文或绑定值。
