# Get Exercise Previews

`GET /student-practice/exercise-previews`

Student-safe batch previews of library exercises.

Used by the chat's training-session card to hydrate `<exercise_ref>`
items before the student accepts the session (and by the teacher chat's
add-exercises card). Ids may belong to `public_exercises` (library gate
applies) or `annales_exercises` (review-flagged rows excluded). The
projection NEVER includes the solution; inaccessible or unknown ids are
silently dropped (the card degrades gracefully). Results come back in
the requested order.

## Query parameters

- `ids` string[], required
- `subject` 'maths' | 'physique-chimie', nullable — Optional matière scope; omitted → any matière.
