## Results

```json
{
  "known_birth_match": 3336,
  "common_lifespan": 600,
  "forced_death": 2736,
  "independent_source_binding": "File18 names2736 explicitly",
  "novelty": "whole-edge synthesis of established source data"
}
```

## Finding

Equal births and equal 600-year lives force equal deaths; the explicit source biography confirms that this is the intended matched state.

## Reassessment

Follow the stage translation to show how the same SP construction meets MT.
