# Desk run-through and known limits

**Educator route.** I took Days 11–14 in order as a new teacher: Source A names a low-stakes object; Source B requires a private school-verified backup; Source C distinguishes a permission refusal from help for a different option; Day 14 combines without reversing a no. The key preparation that cannot come from this public pack is the school's real A/B adult route and immediate response procedure. If that is not filled, teach only the fictional reading and postpone route rehearsal. On Day 15, the newly held silver stencil tray case asks for exact source lines before the key appears. This is a desk review of the written sequence, not a classroom trial.

**Learner and access route.** I walked a no-speaking, no-touch, no-acting route through Days 13 and 18. Pointing/AAC/private source reading reaches the same respectful response or pause reasoning. Broad tactile labels are offered only by choice and secured to avoid loose small pieces. A child can stop or pass without explaining. The educator still must test an individual's actual access, literacy, language and AAC setup locally; text alternatives do not certify accessibility.

**Movement route.** I traced START–A–B on the fictional map, then checked whether the record might mistake adult marker movement for child skill. The lessons and key require **PHYSICAL ACTIVITY NOT OBSERVED** unless a locally approved, chosen, safe actual action occurs and is dated/observed separately. A visible/aural cue is individually agreed, and no race, throw, forced contact or body position is required. Day 20's ferry board is a new paper-only case; it cannot score physical HPE movement. This is a desk simulation, not an observed child outcome.

**Funder and rights route.** A funder can trace exact official rows, original asset hashes, licences and the QCAA boundary without interpreting a fictional child as an impact result. The pack has no measured uptake, learning gain, safety certification or efficacy claim. It needs paid or voluntary educator review and actual classroom feedback before a stronger public claim.

**Checks run on freeze.** The deterministic verifier checks exact official workbook descriptions, ten timed lessons, thirty routes, twenty swaps, ten optional bridges, held-case ID matching across scripts/check/key, fresh-case phrase separation, six A4 SVG/PDF pairs, source/rights text, local links, Markdown list spacing and file hashes. PDF text and visual previews are inspected separately. These checks cannot replace safeguarding, local equipment inspection, individual accessibility review or a classroom pilot.
