Picture the whole framework, then pin the element-kind language layer. System platform layer — rebuild the semantics likec4 can't draw (ADR-0001..0004): - Prelude: opaque Identifiers carrier (ProjectId/RunId/SessionId/Principal) - System/Run: RunState + Terminal subset (set completeness left OPEN, no invented pending) - System/Lock: lock owner=run (typed), LockTable exclusivity, WellFormed invariant (a lock holder must be a non-terminal run — couples Lock and Run) - System/Permission: read<edit<manage role lattice, capability derivation, can_mono monotonicity theorem; force-release sits outside the lattice (admin-only) - System/Audit: intentionally thin (mostly plumbing, OPEN) Courseware product layer — split the single Lesson file into focused modules and fix doc tautology: Primitives / Element / Lesson / Render / Diagnostic, plus QuestionBank and Course skeletons (core relations OPEN, not invented). Diagnostic upgrades WarnsIgnored into a severity-tagged checker rule. Element schema + rich-content model (ADR-0006, ADR-0007): - docs/adr/0006: kind schema is declarative JSON Schema; field types are built-in scalars plus a `content` extension; a `content` value is typst source taken as module body; rich content must carry a VirtualPath (else click-to-jump and relative import break — verified against typst source); import boundary = within the engineering file + @package - docs/adr/0007: on-disk form is a real directory tree (agent/grep friendly); VirtualPath = real relative path; layout conventions deferred - spec/Courseware/RichContent: prose anchor for rich content (opaque VPath, RichContentRef); ElementData kept abstract — JSON/typst internals are implementation detail, not contract lake build green (18 jobs), no sorry, toolchain v4.31.0.

# Course —— 课程编排(骨架,规则 OPEN)
|
|
|
|
ADR-0005:工程文件的粒度是**单节课**;course / 单元**不是**工程文件,而是 lesson
|
|
的**编排**。
|
|
|
|
但"编排"的具体规则未决策:course 是 lesson 的有序列表,还是带层级(单元 → 课)的
|
|
树?编排里 lesson 是被引用还是被包含?跨 lesson 有无约束(目标覆盖、前后置)?这些
|
|
都是 `OPEN`。
|
|
|
|
按宪法第 2 条,本模块**不臆造**编排结构——不建 `Course := List Lesson`(那会偷偷
|
|
承诺"扁平有序、无层级")。只在此 surface:课程编排待专门 ADR。本文件当前不引入任何
|
|
承诺性声明。
