Why: card sections were placeholders (policy requires goal, requirements and test plan before evidence/review); the gitlinks point the composite at the I4 sub-repo commits so make test validates the real combination. Evidence: make test green in this worktree at these gitlinks (log kept locally; CI is authoritative); card edit is SELF. Impact: task card content + submodule pointers (backend 9aa51e5, frontend 01b853f). Refs: WP3-I4.
