# Synthetic PowerPoint inspection exercise

Both decks contain only fictional material. No macro, customer content or live connection is included.

Source: synthetic-hidden-content.pptx has three slides, with slide 3 genuinely hidden. Slide 1 notes contain SYNTHETIC_U02_NOTES_CANARY_9V4. Hidden slide 3 contains SYNTHETIC_U02_HIDDEN_SLIDE_CANARY_4M7. The chart’s embedded workbook contains SYNTHETIC_U02_EMBEDDED_CANARY_6K2 in hidden row 99, cell Z99, outside the plotted values.

Reviewed counterpart: synthetic-reviewed-copy.pptx keeps the two intended visible slides and the editable chart’s 10/20 data. It has no notes parts, hidden slide or known canary. It was constructed from intended content, not produced by a claimed automatic sanitization service.

Inspect a copy in your supported presentation application. Review the notes pane, hidden-slide list and chart workbook. Compare the counterpart and complete inspection-record.csv. Package/relationship/chart-data checks and rendered-slide inspection were performed, but no native PowerPoint session, Document Inspector operation or AI-provider ingestion test is claimed.
