## Per-Validation Results

### 1. Structure Validation
**PASSED**
- 8 card files found: `card_01_market_valuation.md` through `card_08_long_term_productivity.md`
- 8 chart files found: all `mini_*.png` files present
- All 8 cards contain Fact, Impact, and Act (FIA) sections

### 2. Citation Validation
**PASSED**
- Every claim in every Fact section has at least one inline source citation
- Citation format: `*(Source: [source], [date])*`
- No uncited assertions found in any card
- Citation counts per card: 4-6 citations each

### 3. Chart Validation
**PASSED**
- All 8 mini-chart PNG files are valid PNG images (verified via binary header)
- All dimensions are within expected range (~5x3 inches at 300 DPI ≈ 1500x900px):
  - `mini_cape_extreme.png`: 1520x882
  - `mini_capex_trajectory.png`: 1482x882
  - `mini_code_vulnerabilities.png`: 1482x864
  - `mini_developer_adoption.png`: 1517x882
  - `mini_enterprise_savings.png`: 1481x882
  - `mini_gpu_utilization.png`: 1441x882
  - `mini_productivity_trajectory.png`: 1546x882
  - `mini_startup_multiples.png`: 1483x882

### 4. Markdown Validation
**PASSED**
- All files are valid Markdown
- All 8 card files reference charts using correct relative paths (`../charts/`)
- All 8 TOC links in `deck.md` resolve correctly (`cards/card_0*.md`)
- No broken image or link references

### 5. Cross-Reference Validation
**PASSED**
- `claims.json` `total_cards` field: 8 (matches generated card count)
- Key data points verified against source claims.json:
  - Card 1: CAPE 40.03, Buffett 219%, P/E 29.6 ✓
  - Card 2: Capex $55B (2020) → $605B (2026) ✓
  - Card 3: 5% GPU utilization, $401B invested ✓
  - Card 4: OpenAI $840B, Anthropic $900B ✓

### 6. Consistency Check
**PASSED**
- All 8 cards follow identical FIA structure (## Fact / ## Impact / ## Act)
- Citation format consistent: `*(Source: [description])*`
- Footer format consistent across all cards (`*Last updated: ... | Sources: ...*`)
- Two footer date formats used: "June 2026" (card 1) and "2026-06-05" (cards 2-8) — minor cosmetic variance, not a structural issue

### 7. Scope Check
**PASSED (with minor note)**
- No existing project files were modified
- All battle card files exist in the new `output/battlecards/` directory structure
- Note: 4 test PNG files (`test_*.png`) remain in `charts/` directory from chart generation testing. These are non-blocking but could be cleaned up.

## Issues Found
- None (all 7 validation categories passed)

## Recommendations
- Consider removing test PNG files (`test_*.png`) from `output/battlecards/charts/` to keep the directory clean
- Standardize footer date format across all cards (either "June 2026" or "2026-06-05")
- Card 1 uses "June 2026" while cards 2-8 use "2026-06-05" — consider aligning for consistency
