Discharge the layout question ADR-0007 deferred. Fix the engineering-file
on-disk arrangement so the checker recovers lesson order/membership without
evaluating typst:
- manifest.toml at root: [project] + [info] + ordered [[parts]] (kind+path) +
[targets.*]. Array order IS lesson order (ADR-0005). Subsumes the samples'
project.toml/info.toml and replaces main.typ's `#let parts`.
- element.toml per element folder: explicit kind + scalar fields (self-describing,
parent-dir grouping not load-bearing).
- content fields are convention-named <field>.typ siblings; the kind's JSON Schema
(ADR-0006) is the source of truth for which .typ files must exist. Drops the
samples' per-element main.typ wiring (now generated, not hand-authored).
Surfaced gaps (deferred): per-file render override (ADR-0005 says the matrix is
overridable in-file; MVP keeps rules in the render layer, no override), 题库
on-disk layout, manifest richness (per-part metadata, sectioning).

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.

First product-core concept in the semantic master spec: a curriculum
engineering file is one lesson, modeled as an ordered sequence of typed
element instances over an open kind universe.
- docs/adr/0005: lesson model decision narrative + deferred OPEN items
- spec/Spec/Courseware/Lesson.lean: Primitives carrier (KindId/ElementData/
TargetId/RenderRule kept abstract), Element, Lesson, RenderConfig, and the
first checker seed (WarnsIgnored: used-kind-with-no-render-rule => warning)
- wire Spec.lean -> Spec.Courseware; drop placeholder Basic.lean
