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.
