POST /api/studio/courses/:id/convert (owner only, CSRF-guarded by core) queues
studio.convert-import; GET /api/studio/jobs/:id reports progress. Read-only
responses say whether the caller may convert. Resolves TODO(studio) (ruling R9).

- Critical 1 (CSRF): core wrap refuses every POST/PUT/PATCH/DELETE whose Origin
(Referer as fallback) is not publicUrl's origin or STC_ALLOWED_ORIGINS, and
any body that is not application/json (multipart only on declared upload
routes). Better Auth routes go through the same guard; only declared
identity-provider callbacks (SAML ACS/SLO, OAuth callbacks) are exempt.
Better Auth trustedOrigins use the same list. Session cookie stays Lax
(Strict breaks OAuth/OIDC/SAML returns); documented.
- Important 4 / learner minor 4: the first-owner claim and the role row are
one transaction guarded by "no owner yet"; only a unique violation means
learner; any other error fails the sign-up with 500 and removes the
half-created user. Serialised per DB handle (Bun's SQLite connection).
- Important 2 / learner minor 12: code zips stream entry by entry (large
files stored in 256 KB chunks with a data descriptor and incremental
CRC-32), so memory stays at one chunk; the cap is now 1 GiB (ZIP32).
- Important 3 / learner minor 10: the e2e runs the production wiring
(productFeatures order, AI drafts through the real sink) against a
restricted course and asserts 404/401 for learner and anonymous on
course, lesson, media, cover, code, zip, notes, progress, attempts, AI
chat, library, search and AI status; a real Range request (206, 416);
forged writes (foreign Origin, text/plain, no Origin) are 403 and the MCP
test command never runs.
- Minors 7-9: compose passes every documented variable; the health check
uses STC_PORT; productFeatures checks the studio-before-AI order.

Contracts and core:
- Feature gains auth and stop; FeatureFactory; core composeServer builds the
context, runs the factories, then the job queue from the union of their jobs
(R8/R14). startServer uses it; main.ts composes learner, import, studio, AI.
- AppConfig/loadConfig own the layout and settings: courseDirs include
<dataDir>/courses and <dataDir>/worktrees, studioReposDir, cacheDir,
importRoots, uploadMaxMb, aiAllowedBaseUrls, transcribeUrl, python.
resolveConfig derives the same for tests; cachePaths shares the importer's
cache layout.
- canView: the global author role views every course (R14); the learner,
studio and AI packages all call it.
- migrate(db, packages): core first, then packages in name order.
- Media: nosniff on every response, a sandbox CSP on svg/html/js; a Range on
an empty file is 416.
- courseUrl/lessonUrl and the lesson route patterns live in @stc/contracts.
Packages:
- import, studio and AI read AppConfig instead of process.env; the importer
refuses ids used by studio/repos.
- learner migrations run through core migrate; library covers fall back to
the importer's cached candidate behind a canView-checked route.
- studio preview renders through the learner LessonView (anchors honoured,
draft URLs); AI drafts go to the studio draft branch for studio courses (as
the requesting user) and to <dataDir>/drafts otherwise, and the generator
page says which.
Web: tsconfig paths for @stc/<feature>/web browser entries; features.ts
imports them by package name; nav.roles hides links by role.
Tests: compose, config, canView, media headers, migrations order, covers,
preview, nav, SPA bundle without server code, and an end-to-end flow on
SQLite and Postgres.

C1: writes lstat every path component and refuse symlinks (dangling included),
check the parent's real path after mkdir, and open with O_NOFOLLOW.
I1: only https://, ssh:// and git@host: remotes; protocol.file/ext/fd=never on
every fetch and push; global/system git config ignored.
I2: STC_UPLOAD_MAX_MB cap (default 100) by Content-Length and while streaming;
extension allowlist (415); stcourse.yaml refused; 409 unless overwrite=true;
sandboxing CSP on draft raw files.
I3: owner-only visibility/source.kind rule checked on the merged result at
publish and sync, and at resolve; publish also validates the merged tree.
I4: bare repos in <dataDir>/studio/repos/<id>.git; imported courses read-only.
I5: list status comes from the bare repo; drafts are created lazily.
