## Question

Do the two named coarse partitions and the path retaining both source nodes have the same inverse head?

## Finding

LXX Regular shares the Flood/Noah coarse endpoint, but retaining both source nodes raises the head990.

## Reassessment

Test SP without modifying its accepted Fall head or Noah600 interval.

## Checks

```json
{
  "expected_heads": true,
  "same_source_total": true
}
```
