Lift the business decisions the MVP made into the Lean master, per constitution rule 5. lake build green (20 jobs), no sorry. - Artifact.lean: `inductive Artifact | singleFile | fileTree` — product shape is part of a target's value (ADR-0009); it determines the assemble/reduce step. - Render.lean reworked target-centric (ADR-0009, amends ADR-0005's matrix): `TargetSpec` carries `artifact` + a per-kind `renders` map (field visibility lives in this map); `RenderConfig.spec : TargetId → Option TargetSpec`; `covers` rewritten (target must exist AND its map covers the kind) — semantics continuous with ADR-0005 so renderIgnored still typechecks. `BuildStepForm` (declarative | shell) is a structural anchor for the build form (shell hatch = ADR-0005's medium-only category b) without replicating the schema. - Diagnostic.lean extended: `DiagKind` (7 classes) + `DiagKind.severity` (six error, renderIgnored warning); `Oracle` makes external-facility verdicts (compiles/refsResolve/dataConforms/contentFilesPresent) an explicit implementation boundary; `Legal` = no error-level diagnostic (backfills ADR-0005's deferred full-legality), with renderIgnored deliberately excluded (it's a warning). - Pipeline.lean: the 5 phases (load→structural→schema→compile→coverage) as structure — order + the compile gate (compile runs only on zero prior errors) + load halts the pipeline. Algorithms stay out of Lean (depth ceiling). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

# Artifact —— export target 的产物形状
|
|
|
|
ADR-0009:一个 export target 是**一次 build**,产出一个**有类型的产物**(artifact)。
|
|
产物的**形状**是 target 值的一部分——"产出单个文件还是一棵文件树"是真分歧点,因为它
|
|
改变 `cph build` 到底吐出什么、消费方期待什么,故进契约。
|
|
|
|
本模块只钉**形状**这一层。具体后端/格式(用哪个 PDF 引擎、哪种 markdown 方言)是
|
|
ADR-0009 显式 OPEN 的,不在此承诺。

export 产物的形状(`PINNED`, ADR-0009)。
|
|
|
|
- `singleFile` —— 一份打包文档(讲义 PDF、教案 PDF)。
|
|
- `fileTree` —— 一棵文件树 + 索引(第三方平台 archive)。
|
|
|
|
**为什么这是分歧点而非实现细节**:产物是单件还是多件,决定 reduce/assemble 这一步
|
|
怎么折叠(见 `Render`:`singleFile` 按 lesson 序拼成一份文档再编译——这也是交叉引用
|
|
`@ref` 与 例题N 计数器能工作的前提;`fileTree` 每 part 一文件 + 索引),也决定
|
|
`cph build` 写一个文件还是一个目录。后端/格式(typst→PDF、markdown 方言…)仍 OPEN,
|
|
故此处**只枚举形状**,不带后端标签。
