| Original scenarios, drawn-feature card recipes, direct-comparison protocols and twenty optional swaps | All classroom situations and numbers are invented. Card categories are mutually exclusive in each prepared set; arithmetic and group totals are checked. Capacity and mass results depend on **teacher preflight of actual equipment**, not an image or manufacturer label. | © NeuroForgeIO Pty Ltd 2026, [CC BY 4.0](https://creativecommons.org/licenses/by/4.0/) for original teaching expression/data.

| Six original A4 SVG/PDF visual aids, full text and tactile alternatives | Generated from original lines, containers, labels and comparison prompts by [local print generator](print/generate_print.py). PDF text is selectable; colour is never the sole category cue. The check-preparation sheet is public by URL and teacher-targeted. | Original diagram expression CC BY 4.0. PDFs can embed [DejaVu Sans](print/DEJAVU-FONT-LICENSE.txt) under its separate font terms. PDFs are untagged; text/tactile adaptations remain necessary. |
| [Verifier](verify_pack.py), print generator and [SHA-256 receipt](manifest.json) | Validate exact pinned rows, 10 timed days, 30 routes, 20 swaps, fresh checks, arithmetic, A4 output, local links and file hashes. | Original code Apache-2.0 ([licence](CODE-LICENSE.txt)). A passing receipt checks authored artifacts, **not** educator approval, classroom trial or accessibility certification. |

There is no claim that a pictured round leaf belongs to a named plant, that a fictional card distribution reflects local ecology, or that shelter material properties have been scientifically tested. No biological behaviour is inferred beyond what a drawing visibly shows. No small loose pieces, personal finance/home data, forced disclosure, unreviewed translation or invented First Nations language/culture are part of this packet. The two answer keys are public and therefore unsuitable for secure assessment.
