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);
fix live references in open readiness tickets
[targets.*] reworked: artifact is now an inline table with a type discriminator
({type="single-file",filepath} / {type="file-tree",root,outputs}) and steps is an
ordered array-of-tables ({type="typst-compile",template} / {type="shell",run}).
numbering removed entirely (presentation lives in the template per ADR-0011).
TargetConfig { name, artifact: Artifact, steps: Vec<Step> }; Artifact and Step
mirror Spec.Courseware.Artifact / Spec.Courseware.Step (doc-cited). Sensible
defaults so a bare [targets.student] still works: single-file build/<name>.pdf +
one typst-compile exports/<name>.typ. Malformed artifact/step type → non-fatal
SchemaViolation with fallback. 8 tests green.

manifest.toml [targets.*] upgraded from bare names to structured build configs.
Lesson.targets: Vec<String> → Vec<TargetConfig> { name, artifact, numbering }.
ArtifactKind { SingleFile, FileTree } mirrors Spec.Courseware.Artifact.
NumberingConfig.heading: Option<Vec<String>> — None means "use framework
default" (render package owns it), so absence is distinguishable from a value.
Empty [targets.x] body = all defaults, no diagnostics. Malformed config (bad
artifact value, non-array numbering.heading) → non-fatal SchemaViolation, target
kept with defaults. Enabled toml `preserve_order` so target declaration order is
real (the old Vec<String> never actually preserved order). target_names() helper
for call sites that only want names. 8 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).
