iblai-api-studio-subsection

A subsection (sequential) sits inside a section and holds units. It is also the grading unit of Open edX: the assignment type and due date live here, and a subsection marked with a type from the grading policy is what gets graded. Same /xblock/ endpoints as sections, different metadata.

Before you start

1. Preflight: node .claude/skills/iblai-api-studio-auth/scripts/studio-login.mjs --check prints two oks; otherwise run /iblai-api-studio-auth first — do not attempt the calls below.
2. A section locator from /iblai-api-studio-section (or the outline read).
3. For graded subsections: the assignment type exists in /iblai-api-studio-grading, and the course's pacing is decided (/iblai-api-studio-settings) — due dates behave differently on self-paced courses.
