This card is immutable after the public lock timestamp. It is a four-score
pregame prediction, not a certainty claim.

## Validation completed

- 100 of 100 historical input rows passed model admission.
- Two independent model output directories produced byte-identical cards.
- 21 contradiction rows were evaluated.
- 42 of 42 declared stress forks passed.
- C4 retention rates were 100%, 95.8333%, 100%, and 76.25%.

## Validation boundary

The admitted data, calculations, twin output, candidate ordering, and stability
results were checked. Exact historical copies of three execution-time source
files were not retained, so this public freeze does not claim the strongest
possible end-to-end historical provenance certification.
