TEACHING EXPORTS — REAL PRODUCT OUTPUTS, 2026-10-12

source.pdf is a self-authored two-page English sample with three classroom questions and an answer key. It contains no student data.
native/teaching-interactive.html and native/teaching-slides.html are untouched product downloads. Their differences are the initial reading/slides mode and its corresponding toggle-button label. Unzip and open an HTML file in your browser; review the full question and answer content before using it. This sample embeds its formulas and script, but cold offline opening and print output were not tested.
native/teaching-export-original.pptx is the first teaching-copy export, with the table appearing as literal HTML markup and an extra running header on question 3.
native/teaching-export-edited.pptx is a second product download after an actual editor change to question 3: table markup replaced with two explicit data lines, and the extra header removed. The first two slides were unchanged. This does not demonstrate automatic table reconstruction.
checks.json describes the actual checks, hashes and limits.

One PDF upload, one parse start and one organizer task were used. AI supplementary explanations and image enhancement were off. All three source answer pairs were reviewed and saved at revision 1. Teaching-copy edits did not change the organizer or the HTML outputs.
All three HTML answers are combined answer/explanation blocks. The answers are embedded in the file, so hiding them is a display feature, not a security control or grading service.
PPTX has three slides, ten formula SVG images with PNG fallbacks and timing data. Formulas are not native Office math objects. The original has no native table object. Browser classroom preview and same-browser local-save recovery were tested; PowerPoint/WPS playback and cross-device recovery were not.
The teaching editor/PPTX pending-review footers remain present despite confirmed source pairings. Recheck content, labels, font size, wrapping, formula display and answer reveal on the actual presentation computer.
Keep the original PDF and native outputs for comparison.
