Selected Year 8/Years 7 and 8 curriculum descriptions	ACARA Australian Curriculum Version 9.0 downloads, accessed 29 September 2026. Original whole-curriculum XLSX at `products/curriculum-studio/research/sources/acara-australian-curriculum-v9-download-2026-09-29.xlsx`, SHA-256 `db446882d2c00cf7c085a03e250e2442fda6c44011fc114680c46c1dc7a822c3`. Selected exact source rows and wording imported in local `products/curriculum-studio/data/frameworks/acara-v9.json` and generated into crosswalk.	ACARA wording is separately attributed below. No code is claimed complete. Recheck source version and update/sync frequency for any later platform release.
Sources A–G, fresh A/B checks, choices, scripts and worked examples	Written as fictional material for SubjectNest on 29 September 2026. Staff key and verifier check arithmetic, units, factual reach and check separation. All sample data are constructed; teacher-recorded practical data must remain distinct.	© NeuroForgeIO Pty Ltd 2026, CC BY 4.0. No real student, supplier, site, cultural motif or artwork is represented.
Three A4 SVG/PDF aids and offline model tool	Original local vector generator and HTML/JavaScript in this pack. PDFs are deterministic outputs; the tool uses no account, storage or network request. Complete text/tactile aids and offline paper route cover the visual/digital representations.	Original design/text under CC BY 4.0; generator and verifier source code carry Apache-2.0 SPDX notices. The embedded DejaVu font subset retains separate font rights. No assistive-technology compatibility or user benefit is certified.
Science, economics and design claims	Source C is a classroom-scale paper test plus constructed fallback trial counts, not a structural engineering finding. Source E's tokens and quote changes are invented, not market prices. Artist/reader notes are perspectives, not observed population responses.	A local teacher checks practical safety. Do not extrapolate to real mounting, supply markets, accessibility or attendance.
Local curriculum, language and cultural authority	No state/territory syllabus mapping, real place study, First Nations language/ICIP, translation or local approval has been performed.	A school must source broader literature and place/cultural material under appropriate rights and authority, review jurisdiction requirements and validate any translation before use.

Source arithmetic and interpretation checks

B: R(n)=24+18n; T(n)=2R(n)=48+36n. At n4: R96, T192; at n5: R114, T228. Two-rail total is not one-rail width.
C: constructed flat tabs 1,2,1 average 4/3≈1.33; folded 4,4,5 average 13/3≈4.33. The three-tab mean difference is constructed and not a real installation capacity. A descending paper tab can be discussed as potential-to-kinetic energy; no energy quantity was measured.
D: 5+15d≤50 permits whole d0–3; d3=50, d4=65. It counts demonstrations, not visitors.
E: at p4, F20/G16; p8, F28/G32; p6 is 24/24. The invented G six-token what-if at p4 is 24. p counts total panels, whereas B's n counts panels per rail.
Fresh check numbers/answers are in the publicly accessible formative assessment and teacher key, not in teaching pages or the offline tool.
