Three roles: `Student`, `Instructor`, `Admin`. No centralized middleware — each route's loader/action checks `getCurrentUserId(request)` from `app/lib/session.ts` and verifies roles inline. Instructor routes also check course ownership (`course.instructorId`). + +### Route patterns + +Actions use **intent-based dispatch**: a single `action()` handles multiple operations via a hidden `intent` form field, validated with Zod discriminated unions. Example: the instructor route handles `update-title`, `add-module`, `delete-lesson`, etc. all in one action. + +### Validation + +Three Zod helpers in `app/lib/validation.ts`: `parseFormData()`, `parseParams()`, `parseJsonBody()`. Route params are validated with `parseParams(params, schema)`. Form data with `parseFormData(formData, schema)`. + +### Path alias + +`~/*` maps to `app/*` (configured in tsconfig.json). + +## Testing patterns + +Tests live alongside services as `*.test.ts` files.
