TURTLE KINGDOM — VERIFICATION NOTES
Classroom edition 1.0 | 17 September 2026

WHAT WAS CHECKED
- The 56-page PDF was rendered in a PDF renderer. All pages were inspected using contact sheets; representative detailed pages were inspected at a larger size. No page overflow or out-of-page text was found.
- The self-contained HTML was rendered in Chromium from its bytes. All 52 image instances loaded.
- Search, 40 step cards, the 36-step core progress count, image enlargement/closing, note export, JSON backup, reset and backup import were exercised successfully.
- An original turtle-image download and the prepared foam-image download matched their source files byte for byte.
- Desktop and mobile rendering were checked. Both tested viewport widths fit without document-level horizontal overflow after responsive fixes.
- The packaged HTML's 68 local resource references and its internal anchors were checked. No referenced local file or anchor was missing.

WHAT WAS NOT VERIFIED
- These instructions were not executed end-to-end in Photoshop. Tool behaviour was researched in Adobe documentation, but source selections, mask output, transformations, Blend If and colour matching still need a short preflight in the school's installed Photoshop version.
- The managed test browser blocked direct file and localhost navigation. The standalone HTML's bytes were therefore tested in an in-memory Chromium document. Persistent local storage across reopening a downloaded file was not verified. The unavailable-storage warning and manual note/backup export path were tested. Students should export at the end of every session.
- Original stock-image reuse and public-distribution permissions were not all verified. Read Asset_Credits.csv and retain the original credit bands and filenames. Do not treat inclusion as a grant of publication rights.

REFERENCE IMAGES
The step checkpoints and main reference are teaching composites/diagrams assembled from the supplied photographs. They are not actual Photoshop screenshots and are not a pixel-perfect prediction of every student's result. The earlier AI concept is separately labelled inspiration only.

SOURCE DETAIL
Both elaborate castle source photographs are 300 x 400 pixels. Their enlargement will be softer than the AI concept. The 1600 x 1200 document is a practical screen-sized classroom target, not a high-resolution print promise.

CONTENTS
36 core steps, 4 optional extensions, 8 original source images, 8 prepared supports, 31 teaching checkpoint/diagram image files, editable lesson text/JSON and the illustrated PDF. No finished layered PSD is supplied; students build their own.
