The spec/ Lean semantic master had no conformance gate, no codegen, and
no CI tie to implementations — alignment was carried entirely by human
review, the same mechanism that carries the ADRs. In practice the ADRs
plus greppable code comments were already the load-bearing artifacts,
so spec/ was the most expensive kind of stale documentation.
- delete spec/ and the spec-check CI workflow
- README: constitution rewritten around ADRs as decision truth
- AGENTS.md/CLAUDE.md: discipline re-anchored (new decisions -> new ADR,
never rewrite ADR history; supersede instead)
- code comments: re-anchor 'Mirrors Spec.X' invariants to ADR numbers
(cph-diag, cph-check, cph-model, hub runner/capacity/org, prisma)
- leave ADR bodies and .scratch audit snapshots untouched (history);

Integrate the WU-B (structured targets) and WU-C (numbly, config) changes.
cph-typst:
- World resolves any @preview/* package from the in-repo vendored dir
(<render_dir>/vendor/typst-packages/preview/<name>/<version>/), fully offline —
no typst-kit download. Proven: build_pdf_with_real_render compiles the real
render package (which imports @preview/numbly:0.1.0) through the embedded
engine, PDF out.
- Driver threads each target's presentation config: looks up the TargetConfig by
name, emits `config: (numbering: (heading: (...)))` (escaped) when an override
is present, else `config: (:)` (render default).
- target_precheck guards artifact/target: FileTree → blocking diagnostic (MVP is
single-file, deferred per ADR-0009); --target not declared → blocking
diagnostic; no-targets lesson still defaults through.
cph-check:
- Migrated to Lesson.targets: Vec<TargetConfig> (target_names() / target.name at
the 6 sites). Pipeline unchanged (already matches ADR-0010 phases). Documented
that !has_errors() implements Spec.Courseware.Legal (no error-level diagnostic).
Workspace: fmt + clippy -D warnings + all tests green.

Stand up the Rust implementation of the rule-based checker (the thing that
"stands in Lean's position" at product runtime). Single repo-wide cargo
workspace at the repo root so future components (e.g. an exporter) can reuse
shared crates.
- workspace: 6 member crates under crates/; cph-schema/cph-typst/cph-check/
cph-cli are stubs for later WUs that compile clean today.
- cph-diag: shared diagnostic vocabulary. Severity { Warning, Error } mirrors
Spec.Courseware.Diagnostic.Severity exactly (two-valued, no info/note — a
contract decision documented in-code since there's no CI gate for alignment).
Closed DiagCode set with stable string forms; Diagnostic with optional span +
fix hint; Display renders `error[CODE]: msg / --> file:line:col / hint: …`.
- cph-model: the ADR-0008 loader. Reads manifest.toml ([project]/[info]/ordered
[[parts]]/[targets.*]) + each part's element.toml into an ordered Lesson
(mirrors Lean `Lesson = List (Element P)`). Structure-only: cross-checks
part.kind == element.toml kind, rejects `..` traversal; does NOT do schema
validation (WU-3), content-file existence (WU-3), or typst (WU-4).
`load(root) -> (Option<Lesson>, Vec<Diagnostic>)`: Some even on collectible
part errors, None only on hard manifest failure.
- 13 tests (7 cph-diag, 6 cph-model incl. static fixtures doubling as format
docs). build + test + clippy -D warnings + fmt --check all green.
Judgment call flagged for review: cph-diag has no ManifestMalformed code, so
manifest-structure errors map to SchemaViolation (TODO noted in-code).
