## Boundaries a teacher keeps visible

- `23/36≈63.9%` describes **selected Hatch/Ring paper tiles**; `25/48≈52.1%` describes **all fictional paper tiles**. Neither measures real people's reading, visual access, preference, environmental effect, engineering performance or safety. A single maker's in-house line check was not independently repeated. Source C is from the same team as B, not corroboration.
- Any second reviewer, specific print settings, sheet-use tally/offcut choice or public usability study in learner plans is **proposed**, not observed. No new real result is supplied. Real user research would need permission, privacy, appropriate accessibility expertise and local procedures; it is not part of this pack.
- The two checks and teacher-targeted key are publicly accessible. They are fresh relative to lessons, not secure exams. Adapt values/context when prior access affects an assessment inference, and collect first work before feedback.
- No state/territory overlay, First Nations language/cultural content, translation, local community claim, full Year 10 or Years 9–10 band completion, or demonstrated educational impact is asserted. The desk run-through verifies only the supplied pack.
