Evidence boundary
Each code citation points to a teaching opportunity and two narrow fresh transfer samples, not verified student attainment. The count scenarios are invented, so possible combinations do not imply actual game use, accessible print, reader behaviour or classroom outcomes. State/territory syllabus alignment, language editions, First Nations knowledge and broader Year 9 curriculum need separate authorised review.
