I checked the extracted region values, units, zero and missing-value distinction against the PDF. Now create an actual downloadable English PPTX named regional_chart_rebuilt.pptx, with three 16:9 slides based only on the attached synthetic source and verified regional_data.csv.

1. Q3 regional revenue: a native editable PowerPoint column chart, not a screenshot or drawn bars. Include all four regions including the reported zero, label the unit EUR thousands, and use a zero baseline. Embed its editable workbook data. Include source PDF page 1.
2. Data audit: a native editable PowerPoint table showing the Q2 and Q3 region values plus clearly distinguished reported-value sums. Render the not-reported value as a dash with a visible definition; keep the reported zero as 0. Include source PDF page 1.
3. Interpretation limits: keep coverage differences explicit. If you calculate the reported-sum change, label it as not like-for-like. A common-region comparison must identify its regions. Do not explain why a value is zero or invent a business cause. Cite PDF pages 1-2.

Use editable text, readable labels, restrained white/orange styling, and visible synthetic-data disclosure. Do not flatten slides. Return a short downloadable build_checks.md describing the objects delivered and any limitations; do not claim visual or PowerPoint checks you have not actually performed. Do not browse, generate images or change the source values.
