"""
e2e_approval_chain.py — Mutation E2E for the approval workflow.

Walks the full happy path:

  1. APPROVER logs in, lists `?mine=1` → must contain ≥1 pending request.
  2. APPROVER approves the first stage (POST /approve) → state stays
     `in_progress`, current_stage advances.
  3. ADMIN logs in, lists `?mine=1` → must contain the same request now
     pointing to the admin stage.
  4. ADMIN approves the second (final) stage → state becomes `approved`
     and the underlying `encoach.exam.custom` flips to status='published'.
  5. STUDENT logs in and re-fetches /api/student/my-exams (sanity check).

Exits 0 on success, 1 on the first failure.
