Fix the abstraction level review flagged. lake build green (20 jobs), no sorry.
- Artifact.lean: bare enum → ADT with fields — singleFile(filepath) /
fileTree(root, outputs:glob). The product semantics (one file where, vs a tree
of what) are pinned in fields + doc, not erased behind empty constructors.
Paths/globs carried as String (semantics in doc; no filesystem algebra).
- Render.lean: Step inductive (typstCompile(template) | shell(run)) replaces the
loose BuildStepForm. TargetSpec = artifact + steps:List Step + covers:Kind→Prop
(the old renders:Kind→Option RenderRule is gone — coverage is now a plain
declaration; the render "how" lives in the typstCompile template). covers /
renderIgnored semantics continuous with ADR-0005.
- Primitives.lean: RenderRule field removed (the per-target payload is retired per
ADR-0011); a note records where the "how" now lives.
- Diagnostic.lean unchanged in meaning (covers signature stable; Legal still
quantifies over declared targets).

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).

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
