TRA-236 — Course domain model: - courses/models.py: Course → Module → Lesson → Page hierarchy with UUID PKs, ordering fields, required_seconds navigation gate, version tracking, and UniqueConstraint per (parent, order) pair - courses/migrations/0001_initial.py: initial migration (applies cleanly on a fresh DB) - tests/test_course_domain.py: migration smoke, relation integrity, cascade delete, ordering, and uniqueness-constraint tests TRA-238 — Dwell-time tracking: - tracking/models.py: Enrollment, PageProgress (can_advance property), and DwellEvent models appended alongside existing AuditEvent - tracking/services.py: record_dwell_event, compute_eligible_seconds (pure), check_navigation_gate, _recompute_accumulated — reconnect merging within RECONNECT_TOLERANCE_SECONDS and anti-idle cap at MAX_VALID_EVENT_SECONDS - tracking/migrations/0001_initial.py: updated to include all four models (AuditEvent, Enrollment, PageProgress, DwellEvent) with FK dependencies on courses.Course and courses.Page - tests/test_dwell_tracking.py: event replay, reconnect tolerance, anti-idle cap, gate pass/block, and can_advance DB integration tests Co-Authored-By: Paperclip <noreply@paperclip.ing>
