| Claim or asset | Evidence/source | Boundary and reuse |
|---|---|---|
| Decimal rails and fraction equivalences | Exact arithmetic in staff checks, independently recalculated; same-size whole and equal gaps are explicit. | These are mathematical models, not measurements of a real route, site or person's access. All examples and layout are original SubjectNest, CC BY 4.0. |
| Fictional invitation, instruction, explanation and opinion | Original source cards authored for this project. | No real visitor, school policy, local place, family statement or First Nations perspective is asserted. A real setting needs source and permission review. |
| A4 exhibit rail aid | Original SVG drawn for this pack, converted to PDF locally; text/tactile alternative contains the same prompts. | Both formats are original CC BY 4.0. PDF may contain system font embedding under the font's separate licence; font note. No external image, music or recording. |
| Teaching sequence and access options | Original scripts and a simulated desk run-through. | Educator, child, family, disability specialist and local syllabus review are still pending. Options are not fixed learner types; no learning impact is claimed. |
Safety and privacy: Use broad paper parts, dry tabletop materials and school-approved shared space. No sharp tool, glue, hot water, pupil photograph/voice, personal route or account is required. A student can choose no touch and a private audience; record an adult's action separately from the child's decision. A genuine safety or welfare disclosure belongs in the school's safeguarding process, outside this fictional task. If adapted for a real community exhibit, consult the people and knowledge holders whose information is used; do not fill First Nations language or cultural gaps with invented or automated translations.
