# Contract requests from WP-B (Importer)

1. **`loadConfig` should add `<dataDir>/courses` to `courseDirs`.** The importer writes courses there. Worked around in `apps/server/src/main.ts` (the main guard pushes it) and in `packages/feature-import/dev/serve.ts`. `/api/import/info` reports `coursesDirServed` and the UI warns when it is false.
2. **`startServer` accepts feature factories** (`Feature | ((ctx) => Feature)`). A `Feature` needs `ServerContext`, but `ServerContext.jobs` is built from the features' job handlers. `importFeature(ctx)` only reads `ctx` while a job or request runs, so `main.ts` now builds `ctx` first, resolves the factories, then assigns `ctx.jobs`. The edit is about ten lines in `apps/server/src/main.ts`; Phase 2 should keep or replace it.
3. **Web entry for features.** `apps/web` must not pull a package's server code into the browser bundle. `@stc/feature-import` exposes a browser-safe entry as `./web` (package.json `exports`), but the root tsconfig `paths` (`@stc/*` to `packages/*/src`) cannot resolve `@stc/feature-import/web`, so `apps/web/src/features.ts` imports it by relative path. Suggest a tsconfig `paths` entry per feature, or a `src/web.ts` convention.
4. **Derived cache layout (no contract defines one).** Written by the importer, to be read by the learner and AI packages:
   - `<dataDir>/cache/decks/<courseId>/<deckId>/p-001.jpg ...` (1280px wide JPEGs) and `text.json` (`[{ page, text }]`);
   - `<dataDir>/cache/covers/<courseId>/frame-N.jpg` and `deck-<deckId>.jpg` (cover candidates);
   - `<dataDir>/cache/transcripts/<courseId>/<lessonId>.json` (`{ lessonId, text, segments: [{ start, end, text }] }`).
   Suggest a `cacheDir`/`deckPageUrl` helper in core, and a media route for `cache/decks` so the deck viewer can load pages.
5. **Video lessons have no description field.** Packt clips come with a one-line description. It is dropped, because `transcript` is the only Markdown a video lesson can carry and the transcription job writes it.
6. **`STC_IMPORT_ROOTS`** (":"-separated, default `<dataDir>/import-inbox`, created when `importFeature` is built) is read inside the import package. Core config could own it later.
