| [Official ACARA v9 downloads/workbook](https://www.australiancurriculum.edu.au/downloads), dated [source snapshot](source-snapshot.json), and [QCAA ACiQ v9 P–10 Mathematics](https://www.qcaa.qld.edu.au/p-10/aciq/version-9/learning-areas/p-10-mathematics) | Official pages checked 29 September 2026. The locally retained official workbook and import pin all twelve Foundation Mathematics content descriptions by exact code, source row, level and wording in the [crosswalk](CURRICULUM-CROSSWALK.md). QCAA provides the Queensland Prep entry point; this is not QCAA approval of our sequence. | ACARA official wording © ACARA and governed by its [terms](https://www.australiancurriculum.edu.au/copyright-and-terms-of-use). QCAA page remains QCAA content; no page text or resource art is reproduced. |
| Ten original scripts, learner routes, twenty worked swaps, two fresh checks and public key | All examples, source counts, paper displays, audience prompts and arithmetic are invented and desk-checked. A paper audience is labelled model; authentic feedback/work is recorded only if it exists privately. | Original teaching expression/data © NeuroForgeIO Pty Ltd 2026, [CC BY 4.0](https://creativecommons.org/licenses/by/4.0/): credit, link licence, indicate changes. No real child, school, shop or population result. |
| Nine original [A4 SVG/PDF aids](print/TEXT-ALTERNATIVES.md) with text/tactile recipes | Generated from local vector code; one-page A4 PDFs rendered/visually inspected. Check A source counts and Check B part/add/pattern/length geometry verified. Shapes/pictograms have labels/outlines, not colour-only cues. | Original vector expression CC BY 4.0. PDF may embed [DejaVu Sans under separate font terms](print/DEJAVU-FONT-LICENSE.txt). PDFs are **untagged**; use the exact [text/tactile alternatives](print/TEXT-ALTERNATIVES.md). |
| [Deterministic verifier](verify_pack.py), [SHA-256 manifest](manifest.json), [desk review](RUN-THROUGH.md) | Checks exact source hash/rows, ten 25-minute lessons, thirty routes, twenty swaps, fresh public check values, A4/source geometry, local links and file hashes. | Original code Apache-2.0 ([licence](CODE-LICENSE.txt)). A pass proves artifact consistency only, not classroom efficacy, accessibility certification, full-year attainment or formal Queensland assessment compliance. |

**Public formative boundary:** The teacher-targeted key and source pages are public by URL. Keep first child-controlled responses before feedback; if prior access matters, make a fresh local case and key. Store real child records in approved private systems. Do not infer capacity, mass or duration from a drawing, compare differently scaled printouts as though direct, or invent personal, cultural, translation or First Nations data.
