Mode: simulated paper/website walkthrough, 29 September 2026. No child, family, teacher outside the author team, or funder participated. This is a defect-finding exercise, not an outcome study.
Teacher tomorrow
I open the start route, check the two original sources and choose Day 13. I have a blank A4 mat, broad cards and the book-swap row: 46 groups of 18. The lesson gives a 5-minute retrieval, 7-minute model, 10-minute child route, 9-minute challenge and 4-minute evidence note. The key has 828 cards and 72 below limit with a second product route. I can put only Day 13 clean card in a child stack. The setup needs about two paper piles and a readable Source A; no printer is required because the text route replicates the mat. I must fit 35 minutes in addition to English/maths subject blocks and any other required subjects.
Learner with two participation routes
I choose the games plan because I like invented stations. With paper I write 24×37, benchmark 25×40≈1,000, then calculate 888 and explain why the benchmark overshoots. If writing is slow or painful, I point to factor and place cards and direct an adult to record my partition. My mathematical choice is still mine; adult help is logged. A heard source can show what I understood, but it cannot be called independent reading. The flyer cannot tell me who prefers anything. I may decline public presentation, use a private visitor, or make a text/AAC recommendation. The learner cards have no 828/888/928 answers or key link.
Funder or reviewer audit
I can follow the public exact-source crosswalk to ACARA row and wording, reproduce the hash check, read the ownership and font ledger, and see both the lesson count and the unbuilt remainder in the parent year. The 900-card model deliberately avoids unverified cost, popularity and local-place claims. The measurable deliverable is ten authored project blocks with original source and print aids; no classroom effect, state compliance, inclusive-access certification or full-year coverage is claimed. The teacher key is publicly inspectable but labelled staff copy; schools must withhold it until using an assessment. Here Days 15/20 studio examples are explicitly guided after the subject checks.
Defects caught and corrected in this pass
- A rough 25×40≈1,000 estimate might be mistaken for proof that 24×37 breaches the cap. Day 12 now says the estimate triggers an exact calculation, and the key shows 888 fits.
- The garden flyer uses “easily fits” although 29×32=928. Day 14 has learners test and fairly correct that claim, while Day 18 preserves the original factors before showing a new 28×32=896 plan.
- A polished recommendation could hide no arithmetic or source check. Day 19 requires an inspectable product, rule and source limit; the visitor tries to reproduce the reasoning.
- The print PDF may be readable on paper but lacks a tagged-PDF claim. A complete plain-text/tactile route travels beside it and is the digital fallback.
Next human gate: a Year 5 teacher and learners with varied access routes should run an actual block, record timings/first responses and revise. This run-through does not substitute for them. Original SubjectNest review prose © NeuroForgeIO Pty Ltd 2026, CC BY 4.0; credit, link and note changes.
