Declarative JSON Schema per kind (segment/example/lemma/sop), embedded as real .json artifacts (ADR-0006) and validated by a small hand-rolled interpreter (properties/required/type/enum/additionalProperties + the `x-cph-content` marker) — no jsonschema-crate churn for a one-optional-string scalar surface. `x-cph-content: true` marks content fields (not in element.toml; require sibling <field>.typ); everything else is an element.toml scalar. `validate(desc)` is self-contained: UnknownKind for unknown kinds, MissingContentFile (path named in message) for absent required .typ, SchemaViolation for bad scalars; lemma proof optional ⇒ no diagnostic when absent. 8 tests green.

crates/
These crates implement the rule-based lesson checker that aligns to the
semantic master in spec/: it reads an engineering-file (one lesson, ADR-0005)
laid out per ADR-0008 (declarative manifest.toml + per-element
element.toml), validates structure and content, and emits diagnostics.
cph-diag (the shared diagnostic vocabulary), cph-model (the ADR-0008 loader),
and cph-typst (the typst World / compile / span-mapping layer) are
deliberately reusable by future components such as an exporter, which is why
they live in this repo-wide crates/ directory rather than under any single
component; cph-schema (kind JSON Schemas + validation), cph-check
(orchestration + render-coverage) and cph-cli (the cph command-line
entrypoint) are the checker proper.
