feat(checker): cph-typst — embed typst 0.15, driver-gen, compile, PDF (WU-4)
The heart of the pipeline. Embeds the typst 0.15 compiler as a library to compile-check a lesson and export a PDF, with diagnostics mapped back to source spans (the product's value). - LessonWorld: a typst World over the engineering-file directory tree. vpath = real relative path (ADR-0007); the per-target driver is mounted in-memory as `main` (.cph/driver-<target>.typ, never written to disk); @local/cph-render is resolved from render_dir (CPH_RENDER_DIR / with_render_dir), no package install or network. Fonts via typst-kit FontStore (system CJK). - Driver generation: from the manifest, per target — static root-relative `include` of each content file (⇒ module body content, ADR-0006), assembled into the frozen `display(info, target, parts)` call; optional lemma proof emitted only if proof.typ exists; example `source` scalar threaded through. - Diagnostics: typst SourceDiagnostic (errors + warnings) → cph_diag::Diagnostic. 0.15 DiagSpan handled via span.id() + WorldExt::range → file-relative SourceSpan with 1-based line/col; driver-internal spans re-pointed with a "generated driver" hint, never dropped. typst hints/trace carried through. - Engine API: new / with_render_dir / compile_check / build_pdf. - 6 tests incl. build_pdf_with_real_render — full World→driver→cph-render→PDF producing real PDF-1.7 output (student 42KB / teacher 54KB). clippy/fmt clean. Also fixes render/typst.toml `compiler = ">=0.15.0"` → `"0.15.0"`: typst 0.15's manifest parser rejects a `>=` comparator on the compiler field (the 0.14 CLU WU-2 tested against was lenient). This unblocks loading the real render package. Pinned: typst/typst-pdf/typst-syntax/typst-library/typst-layout/typst-kit =0.15.0. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

//! Map typst [`SourceDiagnostic`]s to [`cph_diag::Diagnostic`]s.
|
||||
//!
|
||||
//! ## Span mapping (typst 0.15 specifics)
|
||||
//!
|
||||
//! In 0.15 a diagnostic's `span` is a [`typst::syntax::DiagSpan`] (not the bare
|
||||
//! `Span` of 0.14). To locate it we:
|
||||
//! 1. `span.id() -> Option<FileId>` for the owning file (`None` ⇒ detached, so
|
||||
//! no span is emitted);
|
||||
//! 2. `WorldExt::range(span) -> Option<Range<usize>>` for the byte range — this
|
||||
//! handles every `DiagSpanKind` variant internally (numbered source spans
|
||||
//! *and* raw external byte ranges), so we never match the enum by hand;
|
||||
//! 3. compute 1-based line/col from the file's [`typst::syntax::Source`] via
|
||||
//! `lines().byte_to_line_column` (0-based ⇒ `+1`).
|
||||
//!
|
||||
//! A span whose `FileId` is the generated **driver** is re-pointed: its `file`
|
||||
//! is set to the driver vpath and a hint flags it as driver-internal (a
|
||||
//! driver-gen bug indicator) rather than dropped or mis-attributed to a user
|
||||
//! file. Spans in the `cph-render` package are reported with an
|
||||
//! `@local/cph-render:…` pseudo-path.

//! Driver generation: turn a [`Lesson`] + target into a typst entrypoint that

|

//!
|

//! ## Decisions
|

//!
|

//! - **Include-path style: root-relative (`/segments/…`).** The lesson root is

||||
//! mounted as the typst project root ([`crate::world::LessonWorld`] uses
|
||||
//! `VirtualRoot::Project`), so a leading-`/` path resolves against the root

//! regardless of where the driver itself sits. This keeps include paths
|
||||
//! identical to the part `path`s recorded in the manifest, independent of the
|
||||
//! driver's `.cph/` location.
|
||||
//! - **Content via `include`, not `import`** (ADR-0006): a `content` field's
|
||||
//! value is the module *body*, which `include` yields (`import` would expose
|
||||
//! only `#let` exports).
|
||||
//! - **`@local/cph-render`** is referenced by the standard package import; the
|
||||
//! World resolves it from the render directory (see `crate::world`).
|
||||
//! - **Optional `proof`** (lemma) is emitted only when `<part.dir>/proof.typ`
|
||||
//! exists on disk.
|
||||
//! - **Scalars** (example `source`) come from `part.descriptor.scalars` and are

||||
//! emitted as escaped typst string literals.

//!
|

//! ## File resolution

//!
|

//! - **The driver** (`main()`): mounted in-memory at `VirtualRoot::Project` +
|

//! vpath `/.cph/driver-<target>.typ`. `source()` returns it from the field;
|
||||
//! it is never written to disk. Its root-relative `include "/segments/…"`
|
||||
//! paths therefore anchor at the lesson root.
|
||||
//! - **Project files**: any `FileId` with `VirtualRoot::Project` is read from
|
||||
//! `root.join(vpath.realize)`. Used for content `.typ`, images, `toml()`, etc.
|
||||
//! - **`@local/cph-render`**: a `FileId` whose root is the render package spec
|
||||
//! is read from `render_dir.join(vpath.realize)`. This avoids installing the
|
||||
//! package into the typst local-package directory (MVP: no environment
|
||||
//! coupling). Any *other* `@package` id yields a `NotFound` error (the MVP
|
||||
//! render package has no external `@preview` dependencies).
|
||||
//!
|
||||
//! Sources are cached in a `Mutex<HashMap<FileId, Source>>` so repeated
|
||||
//! accesses during one compilation are cheap, as the `World` contract expects.
