What It Checks

Structural (fast, no rendering):

• AP-01: Wall of Text (>40 words/textbox, >75 words/slide)
• AP-02: Font Size Below Projection Minimum (<18pt body, <24pt title)
• AP-05: Orphan/Widow Lines
• AP-06: Elements Outside 5% Safe Margins
• AP-09: Missing Speaker Notes (<50% of content slides)
• AP-10: Slide Count vs Talk Duration Mismatch
• AP-11: Placeholder Residue (TODO, Lorem ipsum, Click to add)
• AP-14: Too Many Bullet Points (>6 per slide)
• AP-16: Missing Title Slide
• AP-17: Missing Closing/CTA Slide
• AP-19: Text Overflow/Clipping (auto-shrunk below 90%)
• AP-20: Element Overlap (>25%)
• AP-24: Dead/Empty Slides

Contrast & Colour:

• AP-07: Low Contrast Text-on-Background (<7:1 for projection)
• AP-08: Clashing Colours (complementary at high saturation, red-green)
• AP-25: Colourblind Safety (deuteranopia simulation)

Cross-Slide Consistency:

• AP-03: Too Many Font Families (>2)
• AP-04: Inconsistent Bullet Styles
• AP-15: Consecutive Bullet-Heavy Slides (>3 in a row)
• AP-18: Inconsistent Heading Sizes
• AP-23: Branding/Logo Inconsistency

Image Quality:

• AP-12: Image Resolution Too Low for Placement Size
• AP-13: Image Aspect Ratio Distortion (>5%)

Keynote Slide Checks (strategy-aware):

• AP-26: Palette Drift — dominant colours in full_render/backdrop_render images compared against brand palette (RGB distance threshold)

When strategy-map.json exists in the deck directory, QA routes checks per slide:

• full_render slides: skip text checks (AP-01, AP-02, etc.), run image quality + palette drift
• backdrop_render slides: run all standard checks + palette drift
• composed slides: standard 25 checks (unchanged)

Animations & Charts:

• AP-21: Excessive Animation/Transition Types (>2)
• AP-22: Poor Data-Ink Ratio (3D charts, minor gridlines)

Output

QAReport JSON with:

• verdict: pass | pass_with_warnings | fail
• summary: counts of errors, warnings, info
• findings: per-finding entries with slide_number, severity, category, description, suggested_fix, auto_fixable

Verdict Rules

• fail: any finding with severity 'error'
• pass_with_warnings: no errors, but warnings exist
• pass: no errors, no warnings
