1. File Structure Validation: Ensure the presentation strictly adheres to OpenXML (.pptx) standards, utilizing built-in slide masters and layouts rather than blank slides with floating text boxes. 2. Accessibility Checks (WCAG): Verify that every slide has a unique title placeholder to aid navigation. Ensure all non-decorative images, charts, and graphs contain descriptive alt-text. 3. Logical Reading Order: Analyze the z-order of shapes in the slide XML (where back-to-front visual order dictates screen reader sequence) to ensure text is processed logically. 4. Cognitive Load & Formatting: Apply standard presentation heuristics, such as flagging slides that violate the 6x6 rule (more than 6 bullets or 6 words per line) or use fonts smaller than 18pt. 5. Visual Contrast: Calculate the luminosity contrast ratio between text and background elements, requiring a minimum of 4.5:1 for standard text.

## Grounding (do this at runtime)
Do NOT answer precise facts (codes, identifiers, sections, current values) from memory — use the document/data the user provides, and base the answer only on what it returns.
