-- Phase 6D — ROOT 01: Computing & Linux Foundations. Adds 6 modules/activities under the
-- existing (PLANNED, zero-content) root-01-computing-linux-foundations course row seeded by
-- Phase 6A's 022_course_content.sql. Every lab activity references a NEW scenario file
-- (scenarios/data/linux-*.json) using the existing, generic scenario/validation engine — see
-- docs/ROOT_FOUNDATIONS_LAB_STRATEGY.md §1 for why no new activity type or mechanism was
-- needed. Every lesson/demonstration/knowledge_check/guided_exercise/reflection activity
-- references a real content file under content/root/root-01-computing-linux-foundations/.
