| [ACARA v9 downloads](https://www.australiancurriculum.edu.au/downloads) and [official Foundation shape work sample](https://v9.australiancurriculum.edu.au/resources/work-samples/mathematics/foundation/ws02-sorting-shapes-and-objects) | Current pages checked 29 September 2026. Exact official workbook bytes, four content rows, level/area and verbatim descriptions are pinned in [snapshot](source-snapshot.json) and [crosswalk](CURRICULUM-CROSSWALK.md). The work sample informs a broad achievement-standard boundary, not a copied lesson. | © ACARA; [copyright and terms](https://www.australiancurriculum.edu.au/copyright-and-terms-of-use). Official wording is outside SubjectNest's licence; no endorsement. |
| Ten original scripts/cards, twenty optional swaps, two fresh formative checks and public key | All people, settings, pieces and numbers are fictional. Sharing/grouping arithmetic, pattern units and shape descriptions were desk-checked. No real pupil, home, school dispute, class outcome or curriculum mastery is asserted. | © NeuroForgeIO Pty Ltd 2026, [CC BY 4.0](https://creativecommons.org/licenses/by/4.0/) for original teaching expression/data. Credit source, link licence, indicate changes. |
| Eight original A4 SVG/PDF aids plus exact text/tactile alternatives | Generated from original geometry by [local print generator](print/generate_print.py), rendered and visually reviewed. Labels and outlines, rather than colour alone, convey categories. The new check has a child-facing fictional station drawing separate from the publicly reachable teacher setup. | Original vector expression CC BY 4.0. PDFs may embed [DejaVu Sans](print/DEJAVU-FONT-LICENSE.txt) under separate font terms. PDFs are untagged; use [text/tactile alternatives](print/TEXT-ALTERNATIVES.md). |
| Original optional tap/clap WAV and [exact text alternative](audio/TEXT-ALTERNATIVE.md) | Locally synthesized by [generator](audio/generate_audio.py); no recorded person, commercial sound, external voice, music or upload. Sound is an optional second representation of the repeating unit, not a learner classification or required channel. | Original audio CC BY 4.0; generator Apache-2.0 ([code licence](CODE-LICENSE.txt)). Adult tapping or the printed marks can substitute without changing the target. |
| [Verifier](verify_pack.py) and [SHA-256 manifest](manifest.json) | Check exact pinned source rows, ten timed days, 30 routes, 20 swaps, fresh checks, original print/audio structure, links and authored-file hashes. | Original code Apache-2.0. Passing means internal artifact consistency, **not** educator approval, classroom trial or accessibility certification. |

No small loose counters, forced personal disclosure, interpersonal diagnosis, unreviewed translation, invented First Nations language/culture or scientific claim is needed. The two public worked keys are **not secure exams**. When a child directs an adult, record the child's mathematical decisions separately from any adult content cue.
